Knowledge of the individual parts would not yield understanding of the whole, except by seeing the role of the parts as an expression of the whole organism. The concept of integrative levels may help to clarify a nonreductionistic approach to natural events. According to this notion, the order of sciences in Figure 1, from physics up to sociology, reflects levels of integration. Thus, in place of reductionistic continuity, there is discontinuity at each level, beginning at physics. At each higher level, new qualities emerge that were not apparent at lower levels. The implication is that events at each level must be studied at their own level instead of being forced into a lower mold. To reduce phenomena at a higher level to a lower level would be to lose the attributes and structure of the observations that initiated inquiry. The Role of the Hypothetical Construct In some sciences, such as physics and biology, some phenomena can be analyzed to the point at which sight and touch give out and the investigator is forced to resort to submicroscopical concepts-an undesirable situation and certainly not one to be emulated. The relationship between what is perceived and what is conceived in explanatory terms sometimes becomes highly attenuated. This time, a field approach of the interbehavioral type is adopted in investigating psychological occurrences. A first requisite here will be to broaden views to include organism and stimulus object. The center of interest now concerns not what might be imagined to be going on inside the organism, but what transpires between the organism and stimulus object. Their interaction is of paramount, but not exclusive, preoccupation because there are additional observable variables. The interaction requires light to mediate visual interactions and air for auditory interactions. No event occurs in a vacuum, so the setting factors or surrounding conditions in which the event occurs must be noted. All of these aspects of the total event must be seen in system, in their totality. It is hardly possible to overstress the equal emphasis given to the stimulus object, a view that certainly deglamorizes the organism. Scientists come to accept certain events that fit a dependable regularity or "ideal of natural order" as selfexplanatory. These occurrences are accepted as the starting point or base for explaining other things. A rejection of the rock-bottom concept would be illustrated by an investigator who insisted on tearing apart the Earth and the Moon in an attempt to find the "cause" of gravity. They accept gravity as a fact that requires no further explanation, and go to work convinced that gravitation just is. They do not need to dissect it for some imaginary internal "cause" of behavior any more than the astronomer feels compelled to search within the bowels of the Earth or the Moon for the "cause" of gravity. Nonreductionists accept the organism as one of the variables and as a starting point for inquiry, an inquiry that relates the unitary, integrated organism to the stimulus and to other components of the total field. In summary, the difference between reductionistic physiological psychologists and the nonreductionistic variety is what they accept as rock-bottom. On the contrary, the nonreductionist looks on the organism as an important locus of variables than can affect the psychological event. An example using two scenarios in which a boy is reading a book can help make the point in a broad way. In both Event A and Event B, the boy and the book are interacting under definite and specific conditions. Thus the boy in Event B is not the same boy as the one who participated in Event A. Reading that proceeded smoothly in Event A has been interfered with in Event B by a variable localizable within the biological matrix of the boy. This procedure can only lead us back to "merely conceivable" explanations, which themselves call for verification before they can be used. Our consideration of the nervous system as a necessary but not sufficient condition of psychological occurrences paves the way for an expanded inquiry into the question of the organism as a locus of variables.

Group Behavioral Treatment Many universities and hospitals offer professionally led group behavioral treatment for obesity medicine 72 400mg mesalamine mastercard, consisting typically of 16 to treatment tinnitus cheap mesalamine 400mg visa 20 weekly meetings treatment 5th metatarsal fracture buy mesalamine 400 mg lowest price. Key components are food records medications list purchase mesalamine 400mg otc, monitoring of physical activity, behavioral strategies to prevent overeating, and cognitive strategies to promote effective coping with stressors and eating triggers. Calorie prescriptions are given, and increasing both programmed and lifestyle physical activity is strongly emphasized. Physical Activity Professionals debate diet approaches, but there is clear consensus that physical activity is central to weight control and leads to benefits apart from weight loss. Other findings suggest that exercising at home leads to better adherence than does going out to a center and that exercising in several small bouts (i. Recent research raises the possibility that people can be fit at any size and that being fit and fat is better than being unfit and normal weight. This is a helpful concept, as it provides incentive for all individuals to increase their level of physical fitness, regardless of its impact on weight and body size. Increasing activity may be easier than losing weight; hence, some in the field believe that activity should be emphasized over weight loss. The following ideas have been proposed: (1) Regulate food advertising aimed at children; (2) prohibit fast foods and soft drinks from schools; (3) subsidize the sale of healthy foods; (4) tax unhealthy foods; and (5) provide resources for physical activity. The impact of these policy changes on the health of a community is worthy of further study. Conclusion Obesity, along with the poor diet and inactivity that cause it, are major contributors to disease. Obesity is now associated with more chronic illness and greater health care costs than is smoking. The nation must be bold in its response to the epidemic, or the problem will grow worse. Prevention must be a priority, but safe and effective treatments must be available to both adults and children who struggle with their weight. The two most common procedures are gastric bypass and vertical banded gastroplasty. These procedures seem to be gaining popularity, and further research is needed on how best to evaluate candidates and identify predictors of successful outcomes. Laparoscopic procedures are technically complicated but can greatly reduce surgical complications and speed recovery. Different treatments work for different people, so it is unlikely that one best treatment will ever emerge. A more fruitful avenue for research may be to search for the best fit between individuals and programs. Wernicke brought these observations together with new data from aphasic patients with temporal lobe lesions, providing the first neuroanatomical account of both language comprehension and production (Wernicke, 1874). Stigma of Obesity Obesity is a highly stigmatized condition, and obese individuals experience bias and discrimination in many domains of life, including education, employment, and access to medical care. Some argue that the stigma of obesity serves as an incentive for people to try to lose weight. This is faulty logic-if social pressure to be thin worked, we would not have an obesity epidemic. A climate of blame and criticism not only makes weight loss more difficult but also can lead to emotional distress and further eating disturbance. Research is needed on how to ameliorate the stigma of obesity and provide effective coping methods to those who experience it. These word forms (the phonological lexicon in more recent terminology) contain information about the sounds of words, essential for decoding speech sound input and for guiding the production of words. Damage to A thus causes impaired speech comprehension as well as incorrect selection or sequencing of phonemes during speaking (phonemic para- Public Policy Approaches While individual treatments may work for specific people, we believe that reversing the obesity epidemic requires 1034 Table 1. Repetition, which requires both speech sound decoding and production, is also impaired, typically with severe paraphasia. In the classical version of the model, the sound images of words being read must be activated by input from the visual center (center O in the diagram) before reading comprehension can occur, and the sound images of words one intends to write are used to guide the motor images used for writing (stored in center E in the diagram). The deficits resulting from a lesion in A are collectively called Wernicke aphasia. Lesions restricted to the left planum temporale appear to cause only the paraphasic speech component without comprehension disturbance or alexia (Benson et al.

Evidence for and Against the Limbic System Construct Extensive research suggests that limbic structures are important in emotional behavior. Much of the clinical evidence for the unified network concept has come from studies of psychomotor seizures (Jasper, 1964), although recent functional imaging studies in humans also support the notion of a limbic system concept (George et al. Critics of the limbic system construct (Kotter & Meyer, 1992; LeDoux, 1996) point out that no two authorities can agree on which structures should be included in the limbic system. Also, limbic structures are connected with virtually all areas of the brain, so critics argue that one should then consider the whole brain the limbic system. Moreover, if the limbic system is defined functionally as that part of the brain involved in emotion, evidence suggests that the neocortex may be important in the regulation and recognition of emotions and that limbic regions such as the hippocampus and cingulate are important in functions other than emotion, such as memory, cognition, and selective attention. Conclusions Extensive preclinical and clinical observations have suggested that the limbic system structures are critical in emotional behavior. Limbic structures have also been found to be important in social behavior, cognition, and autonomic responses. The limbic system, however, has extensive direct interconnections with all brain regions, and the extent to which the limbic system functions as a network itself remains to be determined. Perhaps the limbic system concept will lose its heuristic appeal as we improve our definitions of emotional states, and the roles of discrete structures and small circuits important in motivation (Kalivas, Churchill, & Romanides, 1999), fear (LeDoux, 1996), and other emotional behaviors. Alternatively, as some imaging studies suggest, we may actually confirm that emotional behaviors do not arise from the activity of single brain regions, but instead emerge from the coordinated action of many connected structures. New techniques in functional imaging and noninvasive regional brain stimulation will allow for direct testing of the limbic system construct in normal function and in psychiatric and medical disorders. Le grand lobe limbique et la scissure limbique dans la serie des mammiferes (Comparative anatomy of the cerebral cortex. Two great figures of that time, William James and Sigmund Freud, loomed large in this issue. Both were trained in medicine and psychology, but viewed themselves as psychologists; both were attracted to philosophy; and both were to receive renown as writers. It is fitting that Freud should have met William James in 1909 on his only visit to America. As he evolved psychoanalysis, he always understood that humanistic studies were vital to his thinking, and he criticized the lack of such studies in the medical curriculum, especially for the training of someone who was to become a psychoanalyst. The specific writers who influenced him were many, including Shakespeare, whose works he had read in English as a youth; Goethe, whom he was fond of quoting; and Dostoyevski, whose psychological acumen he so admired. Humans are linguistic beasts, and Freud recognized that any comprehensive theory of human behavior must come to grips with this simple fact. Freud used the analysis of language as the foundation on which he erected his theoretical edifice. Concepts with linguistic referents inform his analysis of dreamwork, including censorship, condensation, displacement, secondary revision, and symbolization. Similarly, he elaborated how wit and joking are forms of language that reveal the complex workings of the mind. Moreover, Freud evolved a "talking cure," the technique of psychoanalytic therapy in which two people converse as a means of alleviating neurotic suffering. The concern with transformational processes provides a fundamental meeting ground for psychology and literature. We interpret literature and we interpret dreams, and in this way recognize that hermeneutics, the study of the interpretive process, is central to psychology and literature. Freud was preoccupied with these transformational processes in his theory not only in cognition-as in the distinctions of unconscious versus conscious, primary process versus secondary process, repressed versus return of the repressed, and manifest dream versus latent dream-but also in transformation or vicissitudes of instincts, as in love versus hate. This transformational or two-language nature of psychoanalysis brings it into congruence with a number of contemporary approaches to language, including the structuralist approach of the French psychoanalyst Jacques Lacan and the deconstructionist approach of Jacques Derrida. Edelson, who notes that both men posit the presence of deeper structures forming the basis of surface structures, as well as stress the importance of transformational operations by which the language of the deep structure is represented in the language of the surface structure. Fodor is led to speculate on the "vocabulary" of the code by which the private language is transformed into the public language. Literature of the late nineteenth and early twentieth centuries, as in the works of Proust and Joyce, exemplifies the concern with levels of language. It is as if Joyce wished to write in the private language that forms the substrate of all literary works. It is poetry, however, that reveals most directly the transformation process from the private to the public language.
