And if this ‘turning positive’ reflects adaptation generic 400 mg viagra plus free shipping natural erectile dysfunction treatment remedies, can this process of adaptation be explained in terms of functioning discount viagra plus 400 mg erectile dysfunction from smoking, and the paradox be eliminated? But to do so viagra plus 400mg with visa std that causes erectile dysfunction, I first operationalise functioning and individual experience generic viagra plus 400 mg with visa impotence herbal remedies, in section 3. Examples of lower-order functioning are standing, balancing, grasping, holding, and chewing. Again a lower-order functioning is muscle contraction, vision, proprioception, for example. Yet, an intentional activity, lasting for a moment, is usually performed in a context of a pursuit. Pursuits are not observable ex- cept for the present intentional activity that forms part of it. For the practice of re- habilitation, short-term pursuits might be usefully distinguished from long- term pursuits. My de- scription of daily living is to some extent similar to Whitbeck’s definition of health (12), but daily living does not automatically imply health. Daily living is the engagement in distinctively human activities that is directed towards (but not necessarily effectively supportive of) the person’s goals and aspirations. A way of representing levels of functioning based on the notion of a hierarchy of complexity. It is composed of sev- eral lower-level basic activities ba, each of which in its turn is composed of several basic functions bf. Several intentional activities form a short-term pursuit ptst and several short- term pursuits form a long-term pursuit ptlt. The symbol −< indicates from left to right ‘has as com- ponents’; from right to left ‘are component of’. In the following sections, I will operationalise the different levels of functioning. Individual experience will be operationalised using Lazarus’ description of appraisal (18). Relevant levels of functioning are intentional activity, basic activity and basic function. In Figure 3 the com- ponent aspect is reflected not by using branching but using a symbol for a set of components. The symbol −< indicates from left to right ‘has as components’; from right to left ‘are component of’. I propose the following description: An activity can be designated an intentional activity for a particular person – if an instant and single aim, or intention, pertains to that activity, and – if in relation to that activity a pursuit or aspiration can be identified that renders the attainment of the intention of that activity meaning- ful or valuable for that person. Communication Personal care Relationships • to inform • to sleep • to share objects • to explain •to eat and to drink • to take turns • to understand • to wash and to groom • to co-operate • to sympathise • to dress or undress • to join in • to comfort • to maintain continence • to greet • to cuddle Mobility Occupation • to make love •to use different forms • to provide for meals of transport • to carry out household activities • to go around walking • to carry out professional activities • to carry out leisure activities 1 Adapted from the Rehabilitation Activities Profile developed by Bennekom and Jelles (23). Outcomes of measurement of intentional activities can be related to performance as well as to reaching the intention. Also the attainment of an aspiration could serve as an outcome of measurement of intentional ac- tivity, but such an outcome represents a distal outcome, relating less di- rectly to the intentional activity. Outcomes relating to performance of an activity can be described in terms of action characteristics, e. Outcomes in terms of reaching the intention of an activity can be described in terms of intention or direct purpose such as: to get food inside the body (to eat), to get covered or kept warm (to dress), to get darts in the right field (to play). Similarly, the intention guiding the intentional activity to dress could be for example: earning one’s living as a mannequin. The intention directing the intentional activity to play darts could be for example to become the regional champion. But also the relevance of activ- ity and pursuit for the person concerned should be known (21). They can be considered the neutral equivalent of Nagi’s functional limitation (24,25). The distinction of basic activities is useful in clinical practice for a number of reasons. Thus they may clarify the relations between bio- medical conditions on the one hand, and intentional activities on the oth- er. Furthermore, in the practice of rehabilitation this level of functioning is very much the focus of the different disciplines. Examples are gross motor function, balance, reaching, grasping, and oral motor skills. These terms are used, among others, in physiotherapy, occupational therapy and speech therapy. I propose the following description: A function can be designated a ba- sic activity – if it forms a component of an intentional activity, and – if an identifiable receptive and executive aspect is interwoven in the function, and – if it can be performed consciously but usually is performed with a high degree of automaticity, and – if it is composed of body functions. Outcomes of measurement of basic activities will usually be in terms of performance, which can be expressed in pattern, sustenance, efficiency, range, and speed, for example. As regards assessment of basic activities, the meaning of the outcome of measurement often regards the underlying mechanism and, in case of disturbance, a certain diagnosis. The relevance of determining the mean- ing of the outcome also appears from the setting of measurement. Focusing Expressing Moving • directing attention • speaking • walking • sustaining attention • gesticulating • swaying leg • dividing attention •remembering Digesting Manipulating • swallowing • throwing Manifesting emotions • chewing • using scissors • showing empathy • kicking a ball • showing anger Positioning • showing joy • sustaining position • changing position Perceiving • keeping balance • looking • standing • listening • bending • tasting • kneeling • touching e. However, performance of such a basic activity on request will come very close to performing an intentional ac- tivity. The intention of such an activity is for example ‘showing the pro- fessional a certain movement or act’. This is in accordance with the ob- servation that the performance of a basic activity as part of an intention- al activity will be different from the performance in its own right and on request. Al- though basic functions are considered by many authors to be intrinsic characteristics of the person, whether impaired or not, functioning at this level still can be conceived of as interaction. For example, strong or weak muscle strength is called strong or weak in relation to counterforces from the environment. Such counterforces could for example be the profes- sional’s muscle strength in testing. They can help in assessing the condition of the body in terms of confirming or rejecting disease, injury, congenital or other dis- order, or ageing. Furthermore, they can provide information as to what extent organs or organ systems function well. I therefore propose the following description: a function is a basic function – if it is a component of a basic activity, and – if this function cannot be performed voluntarily in isolation, and – if a decrease can be directly related to disease, injury, congenital or other disorder, or ageing. Functions regarding movement, Visceral functions: Functions regarding including peripheral nerves: • heart-lung function exteroception: • muscle contraction • bowel function • hearing •proprioception •bladder function • seeing • range of motion • feeling Sexual functions: • smelling •orgasm • tasting • vaginal lubrication •erection • ejaculation Outcome of measurement of basic functions can be related to the pur- pose of measurement. For assessing a quality of a basic func- tion, grading along a continuum could be preferable. Thereafter I suggested three different categories of mo- mentary functioning: intentional activity, basic activity and basic function (Figure 4B). Figure 4B represents P being the subject and E being the envi- ronment of three different categories of functioning. Figure 4C represents three different categories of person and environment characteristics.

If one group of birds is exposed to another with a latent infection, then a severe disease outbreak can occur. While the carrier birds may be clinically inconspicuous, the virus may propagate at a low level 32 and shed through the feces, urine, respiratory secre- tions or exfoliated epithelial cells from the feathers or skin. In some cases, latently infected birds may succumb to disease, with the virus replicating very rapidly, and both groups of birds may become sick. Artificial incubation and shipping of eggs has been suggested as a method to protect a given population from introduction of an exogenous virus. Infected neonates can cause severe epornitics with high mortality in a nursery situation. Non- specific supportive care, antimicrobials to prevent secondary bacterial and fungal infections and good nutritional support, including the supplementation Helga Gerlach of vitamin C, remain the only available therapeutic regimens for most viral infections. Substantial viral disease outbreaks may be prevented by having a working knowledge of the transmission routes and pathogenesis of a par- ticular virus, by using specific diagnostic tests to detect clinical or subclinical infections, by practicing sound hygiene and by maintaining closed aviaries. Virus adaptation on specific host cells may be diffi- cult to overcome with the routine avian culture sys- tems, and great patience might be necessary when trying adaptation passages (at least ten or more). Continued international cooperation will be manda- tory for the expansion of knowledge in the field of avian virology.

The best forms of non-heme iron are ferrous succinate cheap viagra plus 400mg line erectile dysfunction age 40, glycinate order viagra plus 400 mg on-line erectile dysfunction daily pill, fumarate viagra plus 400mg low price erectile dysfunction blue pill, and pyrophosphate order viagra plus 400 mg without a prescription erectile dysfunction medication does not work. Of these, we prefer ferrous pyrophosphate that is micronized (made into a very small particle size) and then microencapsulated. The advantages of this form include that it is extremely stable, has no taste or flavor, is free from gastrointestinal side effects, and provides a sustained-release form of iron (up to 12 hours) with a high relative bioavailability, especially if it is taken on an empty stomach. High intakes of other minerals, particularly calcium, magnesium, and zinc, can interfere with iron absorption, so in treating iron deficiency it is recommended to take iron away from other mineral supplements. Good nonmeat sources of iron include fish, beans, molasses, dried fruits, whole grain and enriched breads, and green leafy vegetables. The table below provides the iron content per serving of some of the better sources of iron. For example, the absorption rate for the iron in calf liver is nearly 30%, while the absorption rate for the iron in vegetable sources is approximately 5%. Acute iron poisoning in infants can result in serious consequences: damage to the intestinal lining, liver failure, nausea and vomiting, and shock. Support for Vitamin B12 Deficiency Anemia In 1926, it was shown that injectable liver extracts were effective in the treatment of pernicious anemia. Soon after, active concentrates of liver became available for intramuscular as well as oral administration. Today, the use of liver and liver extracts has fallen out of favor in mainstream medicine. For pernicious anemia, standard medical treatment involves injecting vitamin B12 at a dose of 1,000 mcg per day for one week, but oral therapy has shown equal effectiveness (discussed in the section “Oral Versus Injectable B12,” below). The richest sources are liver and kidney, followed by eggs, fish, cheese, and meat. Vegans are often told that fermented foods such as tempeh and miso are excellent sources of vitamin B12. However, in addition to tremendous variation of B12 content in fermented foods, there is some evidence that the form of B12 in these foods is not the form that meets the human body’s requirements and is therefore useless. Although the vitamin B12 content of these foods is in the same range as beef, it is not known how well this form is utilized. Therefore, at this time we recommend that vegetarians, and particularly vegans, supplement their diets with vitamin B12. However, vitamin B12 is active in only two forms: methylcobalamin and adenosylcobalamin. Methylcobalamin is the only active form of vitamin B12 that is available commercially in tablet form in the United States. While methylcobalamin is active immediately upon absorption, cyanocobalamin must be converted by the body to either methylcobalamin or adenosylcobalamin. Cyanocobalamin is not active in many experimental models, while both methylcobalamin and adenosylcobalamin demonstrate exceptional activity. Injectable B12 Although it is popular to inject vitamin B12, injection is not necessary; the oral administration of an appropriate dosage, even in the absence of intrinsic factor, can result in effective elevations of vitamin B12 levels in the blood. In the United States, oral vitamin B12 therapy is rarely used despite the fact that it has been shown to be fully (100%) effective in the long-term treatment of pernicious anemia. Oral preparations containing intrinsic factor were tried, but some patients developed antibodies against intrinsic factor and therefore would not respond. Studies in the 1950s and 1960s soon documented that a small but constant proportion of an oral dose of cyanocobalamin was absorbed even without intrinsic factor through the process of diffusion, so by sufficiently increasing the dose, adequate absorption could be attained. A study in 1978 described 64 Swedish patients with pernicious anemia and other vitamin B12 deficiency states who were treated with 1,000 mcg of oral cyanocobalamin per day. Since that time numerous other studies have all confirmed the effectiveness of oral therapy with vitamin B for pernicious anemia. Physicians have erroneously been educated by medical texts that state that oral vitamin B12 therapy for pernicious anemia is “unpredictable,” has poor patient compliance, and is more costly. These same texts then state that oral cobalamin is effective and can be used when injection therapy is problematic, but the bias against oral treatment has already been established. In a survey of internists, 91% erroneously believed that vitamin B12 could not be absorbed in sufficient quantities without intrinsic factor. Interestingly, 88% of these doctors also stated that an effective oral vitamin B12 therapy would be useful in their practice and further added that it would be their preferred method of delivery if it was effective. Pharmacopoeia Anti-Anemia Preparations Advisory Board in 1959 to caution against oral therapy for pernicious anemia as being, “at best, unpredictably effective. It has been established that the average absorption rate of oral cyanocobalamin by patients with pernicious anemia is 1. Thus an oral dosage of 100 to 250 mcg per day results in a average absorption of 1. The bottom line is that higher dosages are necessary in order for most patients to benefit from oral therapy. It simply does not make any sense, especially since studies with oral cobalamin have shown excellent compliance. In many cases, the compliance is higher with an oral preparation, since many patients prefer taking a pill over getting a shot. The facts are that the two forms— injectable and oral—do not differ much in price for the vitamin B12 itself. The difference is in the cost charged to administer the vitamin B12 injection—anywhere from $20 in a private practice to $100 in a nursing home. It should be obvious that there is no basis for the dogmatic belief that vitamin B12 must be administered by injection in order to produce clinical benefit. In the treatment of pernicious anemia, the usual dosage recommended by most medical texts is 1,000 mcg weekly for eight weeks, then once a month for life. For oral vitamin B12, the recommended dosage is 2,000 mcg per day (14,000 mcg weekly) for at least one month, followed by a daily intake of 1,000 mcg. Support for Folic Acid Deficiency Anemia The diet should focus on foods high in folic acid: liver, asparagus, dried beans, brewer’s yeast, dark green leafy vegetables, and whole grains. Since folic acid is destroyed by heat and light, fruits and vegetables should be eaten fresh or with very little cooking. To replenish folic acid stores, 800–1,000 mcg of folic acid should be taken every day for up to one month. Folic acid is available as folic acid (folate) and folinic acid (5-methyltetrahydrofolate). In order to utilize folic acid, the body must first convert it to tetrahydrofolate and then add a methyl group to form 5-methyltetrahydrofolate (folinic acid). Therefore, supplying the body with 5- methyltetrahydrofolate bypasses these steps and is needed for those with a genetic inability to make the conversion. Folinic acid is the most active form of folic acid and has been shown to be more efficient at raising body stores than folic acid.

Possibilities that may exist to resolve this by greater interdependence amongst workers within the region are hampered by a serious lack of information discount viagra plus 400 mg visa erectile dysfunction performance anxiety, and correction of this situation would result in advantages in several respects viagra plus 400 mg with visa erectile dysfunction drugs in ghana. International agencies and governments providing aid play a major role in the above matters as well as in others such as the provision of consultant services and research contracts which are considered to be of great benefit discount viagra plus 400mg mastercard top rated erectile dysfunction pills. It is stressed that a correct attitude is as important as expertise for the realization of an expert assignment generic viagra plus 400mg with mastercard what causes erectile dysfunction yahoo. In conclusion it is suggested that under existing conditions, third-world workers could abandon the attitude of looking towards the developed countries as first choice for solutions to problems and seek to exploit the potential available among themselves for mutual benefit. In considering the problems associated with the introduction and develop­ ment of immunoassays in developing countries, it is necessary initially to draw attention to the fact that all countries categorized as belonging to the ‘devolping’ world cannot be considered as a single composite unit from the point of view of existing possibilities. This important proviso being made, the problems themselves may be considered as first, those concerned with organization and, second, those concerned with operation of assay services. The health services in many such countries, on which the majority of people depend, are provided by the Government entirely free of charge, or at heavily subsidized rates. As a result, Government authorities have defined systems of priority for allocation of funds from limited health budgets. It is of importance therefore that relevance to national developmental activities, and this not merely in the health field, be stressed at an early stage, and in so doing the following could be emphasized to advantage: (a) Relevance to major health problems for diagnosis and treatment; (b) Applicability to other fields given high national priority such as animal husbandry and agriculture; (c) Advantages provided for research into local problems in the above fields as well as in others. In the medical sphere, recent developments in immunoassay techniques, extending their applicability to nutritional, bacterial and parasitic disorders, underscore their relevance to developing countries where these constitute the major health problems. To cite an example, if it be desired to set up assays for gonadal steroid hormones and if the only justification made is that these would be of use in the investigation of disorders of reproductive endocrinology, the response is likely to be merely lukewarm. If, however, the potential value of the techniques when established to workers in other fields where they are of equally direct relevance, such as in animal husbandry — viz. The manner of initial approach could therefore be a vital one, particularly in third-world countries — and here again some are more rigid than others - where scientists are not given a free hand and virtually nothing can be done, even when no local funds are being utilized, unless it is shown to be in conformity with governmental policies. The question of location of immunoassay centres in the third world is an im portant one to be decided, when a choice is possible, based on criteria different to those that may be applied in the developed countries. Such a centre must not exist for mere prestige value or to serve a microscopic fraction of the community, such as for patients in a hospital. A primary consideration therefore would be the degree to which its services could be extended to include a large population within a wide geographical area, and the nature and magnitude of the practical problems that would follow. A further consideration would be the extent to which the potential of immunoassays, as having a multi-disciplinary applicability and relevance in many fields, could be realized by a sharing of facilities with other workers as far as possible. On the other hand, it is often the case that even where the above requirements could be met, under existing circumstances there is failure of implementation owing to administrative problems and bureaucratic obstinacy which, although doubtless also encountered elsewhere, exerts its worst counter­ productive effects in the poorer countries. Necessary administrative arrangements that are of minor concern in some countries may present formidable difficulties in others. If obdurate customs officials, who would give no more priority to a package of isotopes than to one containing mundane materials, are encountered the problem must be dealt with at an early stage at a sufficiently high level and in a formal and definitive way so that frustrating processes do not have to be gone through on every occasion. Similarly, some forethought may be required to arrange transport of materials to user laboratories from arrival points in the country if, as is often the case, significant distances are involved. Some of the best achievements as well as great disappointments have been seen in this area. This drastic step is not recommended, nor is it likely to be generally followed, but nevertheless certain reasons may be suggested as to why well-intentioned and expensive training is sometimes wasted. Up to now, most training of personnel from developing countries has been undertaken in advanced western laboratories, many of which have little awareness of conditions in the trainee’s homeland. In itself this is not necessarily a major drawback and may be overcome should there be close and direct communication between host and recipient laboratories whenever a trainee is sent to a foreign country, so that what is learned is relevant to what is needed. Very few western laboratories run training programmes consciously designed to suit the needs of developing countries, but it must be acknowledged here that those who are aware of this problem and do attem pt to organize such programmes have made a great contribution indeed towards the progress of immunoassay in such countries. What commonly happens is that a trainee, found a placement on an ad hoc basis, finds himself involved in whatever specialized interest the training laboratory happens to be pursuing at that time. Training thus tends to be in techniques rather than in principles, resulting in the trainee being not sufficiently knowledgeable or adaptable to work in a different field under different conditions on his return. These remarks must not be misconstrued to mean that training for personnel from developing countries is required only at a most basic or elementary level. It is not possible to make blanket generalizations with regard to the level of sophistication of training, which must be decided upon in each case depending on the degree of expertise and other resources available in the home country and the extent of upgrading of these that is required. The hallmark of good training in the context of developing countries is adaptability to local situations and the better the training the more proficient the trainee would be in this respect. Attention has already been drawn to the advantages of close contact between host and recipient laboratories on the question of training, but in the final analysis those likely to benefit most by exposure to advanced western laboratories would be chiefly academic personnel with high educational levels, perhaps pursuing postgraduate degrees, or else senior technicians with some experience. At a lower level there would be many advantages in organizing as much training as possible within the region, in selected laboratories and by means of training courses organized on a regional basis. Here, trainees would encounter conditions more allied to those prevailing in the home situation, the techniques employed and the equipment used would be more similar and, as a minor but sometimes important point, they would encounter less difficulty in the way of personal problems and adaption to different cultural environments. Having drawn attention to the advantages of making the best use of facilities within a region, wherever possible, on the subject of training, it could now be stated that the principle could be applied to an even greater effect to the question of provision of suitable equipment and consumable supplies. Almost all major equipment items in developing countries are of western manufacture, though exceptions to this rule are being increasingly found with some items being locally made or assembled under licence. A reasonable and realistic standpoint on the vexed question of the sort of equipment most suitable for developing countries can only be reached if the situation is viewed in its true perspective avoiding, on the one hand, such simplistic notions as that these countries have no manpower problem because, technicians are available ‘ad lib’ from the vast reservoir of the unemployed, and on the other hand, tub-thumping pronouncements that the third world is being duped to serve as the dumping ground of unsuitable equipment for the benefit of western manufacturers. The actual situation is that in many developing countries there is at present a sufficiently high level of expertise as would allow the use of reasonably sophisticated nuclear medicine instruments such as counters, and where this is not yet so the situation is fast changing. Any degree of sophistica­ tion is acceptable within the framework of these conditions. It follows that its equipment should be such as would enable it to perform this function efficiently. With regard to the second point, inattention, lethargy, and lack of proper planning are found to be more at fault for the present situation where instruments malfunction all too frequently and are allowed to remain in that condition for long periods, rather than lack of technical expertise itself. The importance of matters such as housing instruments in suitable conditions of temperature and humidity and the provision of clean and stable power supplies is not realized, or no attention is paid to it. The fact that collaboration and co-operation between different departments or institutions is not always readily forthcoming is not a feature of developing countries alone, but the problem appears to be most acute where the need is greatest and the ivory towers may be more impregnable. An an example, a laboratory may not be able to utilize the services of an electronics engineer or technician from a different institution for no other reason than that a financial heading cannot be found under which the travelling costs involved could be accounted, not that the funds are unavailable. Although this picture may seem depressing, these problems are entirely solvable but not easily, or as a matter of course, and attention to them needs to be paid, not after the problems have occurred but well in advance, at the planning stage itself. Instances may also be related of instruments obtained by laboratories with so little forethought that the most ordinary or common sense factors have been overlooked. The voltage of a country’s power supply may be found inappropriate to that for which the instrument is designed to operate, only after its arrival in the country. Battery-operated survey meters, radiation monitors, or portable thyroid uptake measurement units are found to be fitted with special types of batteries locally unavailable when similar models using standard batteries could have been obtained. Certain responsibilities in this regard also accrue on instrument manufacturers and suppliers.

His experiments proved that the best way to break a habit is to form a clear mental image of the desired end result viagra plus 400 mg generic erectile dysfunction brands, and to practice without effort toward reaching that goal 400 mg viagra plus sale erectile dysfunction las vegas. Dunlap found that either "positive practice" (refraining from the habit) or "nega- tive practice" (performing the habit consciously and volun- tarily) buy viagra plus 400 mg with mastercard erectile dysfunction treatment for diabetes, would have beneficial effect provided the desired end result was kept constantly in mind viagra plus 400 mg low cost erectile dysfunction san antonio. The im- portant factor in learning, in short, is the thought of an objective to be attained, either as a specific behavior pat- tern or as the result of the behavior, together with a de- sire for the attainment of the object. Greene, found- er of the National Hospital for Speech Disorders, New York City, had a motto: "When they can relax, they can talk. Chappell has pointed out that often the effort or "will power" used to fight against or resist worry, is the very thing that perpetuates worry and keeps it going. Physical relaxation also, in it- self, has a powerful influence in "dehypnotizing" us from negative attitudes and reaction patterns. Consciously "let go" the various muscle groups as much as possible without making too much of an effort of it. Just consciously pay attention to the various parts of your body and let go a little. You can let your hands, your arms, your shoulders, legs, become a little more relaxed than they are. Spend about five minutes on this and then stop paying any attention to your muscles. From here on you will relax more and more by using your creative mechanism to automatically bring about a relaxed condition. In short, you are going to use "goal pictures," held in imagination and let your auto- matic mechanism realize those goals for you. See these very heavy concrete legs sulking far down into the mattress from their sheer weight. They also are very heavy and are sinking down into the bed and exerting tremendous pressure against the bed. The strings which control your jaw and hold your lips together have slackened and stretched to such an ex- tent that your chin has dropped down loosely against your chest. All the various strings which connect the var- ious parts of your body are loose and limp and your body is just sprawled loosely across the bed. Your legs begin to collapse and continue until they consist only of deflated rubber tubes, lying flat against the bed. Next a valve is opened in your chest and as the air begins to escape, your entire trunk begins to collapse limply against the bed. Pick out your own relaxing picture from your past and call up detailed memory images. Maybe you remember sitting per- fectly relaxed, and somewhat drowsy before an open fire- place long ago. Could you feel the warm re- laxing sun, touching your body, almost as a physical thing? The more of these incidental details you can remember and picture to yourself, the more successful you will be. Daily practice will bring these mental pictures, or memories, clearer and clearer. Practice will strengthen the tie-in be- tween mental image and physical sensation. You will be- come more and more proficient in relaxation, and this in itself will be "remembered" in future practice sessions. There is a widely accepted fallacy that rational, logical, conscious thinking has no power over unconscious proc- esses or mechanisms, and that to change negative be-_ liefs, feelings or behavior, it is necessary to dig down and dredge up material from the "unconscious. It always tries to react appropriately to your current beliefs and inter- pretations concerning environment. It always seeks to give you appropriate feelings, and to accomplish the goals which you consciously determine upon. It works only upon the data which you feed it in the form of ideas, be- liefs, interpretations, opinions. Schindler, of the famous Monroe Clinic, Monroe, Wisconsin, won nation-wide fame for his outstanding success in helping unhappy, neurotic people regain the joy of living and return to productive, happy lives. One of the keys to his method of treatment was what he called "conscious thought control. Regard- less of the omissions and commissions of the past," he said, "a person has to start in the present to acquire some maturity so that the future may be better than the past. The present and the future depend on learning new habits and new ways of looking at old problems. This common denominator is that the patient has forgotten how, or probably never learned how, to control his present thinking to produce enjoyment. As we have pointed out earlier, all skill learning is accom- plished by trial and error, by making a trial, missing the mark, consciously remembering the degree of error, and making correction on the next trial—until finally a "hit," or successful attempt is accomplished. The successful re- action pattern is then remembered, or recalled, and "imi- tated" on future trials. This is true for a man learning to pitch horseshoes, throw darts, sing, drive a car, play golf, get along socially with other human beings, or any other skill. Thus, all servo-mechanisms, by their very nature contain "memories" of past errors, failures, pain- ful and negative experiences. These negative experiences do not inhibit, but contribute to the learning process, as long as they are used properly as "negative feedback data," and are seen as deviations from the positive goal which is desired. However, as soon as the error has been recognized as such, and correction of course made, it is equally impor- tant that the error be consciously forgotten, and the suc- cessful attempt remembered and "dwelt upon. Our errors, mistakes, failures, and sometimes even our humiliations, were necessary steps in the learning process. If we consciously dwell upon the error, or consciously feel guilty about the error, and keep berating ourselves because of it, then—unwit- tingly—the error or failure itself becomes the "goal" which is consciously held in imagination and memory. The un- happiest of mortals is that man who insists upon reliving the past, over and over in imagination—continually criti- cising himself for past mistakes—continually condemning himself for past sins. I shall never forget one of my women patients who tor- tured herself with her unhappy past, so much so that she destroyed any chance for happiness in the present. She had lived for years in bitterness and resentment, as a direct re- sult of a serious harelip that caused her to shun people, and to develop over the years a personality that was stunted, crabby, and completely turned against the world and everything in it. She had no friends because she imag- ined that no one would be friendly with a person who looked so "awful. She tried to make the adjustment and to begin living with people in harmony and friendliness, but found that her past experiences kept getting in the way. She felt that, despite her new appearance, she could not make friends and be happy because no one would forgive her for what she had been before the operation. She wound up making the same mistakes she had made before and was as un- happy as ever. She did not really begin to live until she learned to stop condemning herself for what she had been in the past and to stop reliving in her imagination all the unhappy events that had brought her to my office for surgery. Continually criticising yourself for past mistakes and errors does not help matters, but on the other hand tends to perpetuate the very behavior you would change. Memories of past failures can adversely affect present per- formance, if we dwell upon them and foolishly conclude —"I failed yesterday—therefore it follows that I will fail again today.
