A survey is made of a number of experiments conducted in our laboratory over the last six years. Our working hypothesis assumes that positive energy balance, which should not be prematurely defined as the cause of obesity, is itself caused by disturbances in appetite and satiation control which, given certain environmental conditions, can favour the occurrence of obesity. Three points are considered: (1) The hyperphagic reaction as a response to stress. The experimental findings suggest that the hyperphagic reaction is not primarily a biologically determined phenomenon but rather a learned response. The hyperphagic reaction is found more frequently in female and overweight persons. Most children react to stress with a decrease in food consumption. (2) Disturbances of satiation control. The food intake of obese Ss has a linear time function, whilst children and normal weight adults reveal a biological, negatively accelerated satiation curve. (3) Increased responsiveness to external cues. The concept of externality is extended to include the aspect of an internal-external stimulus discrepancy. The findings show that not only manifest obese Ss but also latent obese Ss are characterized by an increased responsiveness to external cues. In three different experiments with the same Ss it could be demonstrated that externality is to a greater or lesser extent independent of the experimental procedure. Finally, methodological aspects are discussed, because in studies on human appetite the possibility exists that experimental procedure, sample composition and laboratory conditions can exert a direct influence on the results.

Understanding the gains and losses experienced by the patient and his family aids in assessing the psychologic sequela of peripheral vascular surgery. Placing the patients' individual responses into the categories of: function, self-directiveness, self-definition, and future orientation offers a way to conceptualize the meaning of the illness to the patient. Factors such as physical mobility and integrity, self-concept and body image greatly influence the adaption process. Conceptually, these elements provide a framework upon which to base nursing intervention. Careful observation, skillful interviewing, and interpersonal support are appropriate nursing considerations when caring for the patient with peripheral vascular disease. The goal of adaption is a successful reintegration of the whole person,which comes from an acceptance of both gains and losses experienced in surviving peripheral vascular surgery.
Internally oriented patients' scores on Rotter's Internal-External Locus of Control Scale remained the same over treatment but those of externally oriented patients shifted toward greater internal control.
To investigate how coping behaviors may be preconditioned by assertiveness and locus of control, a questionnaire was given to 133 undergraduates of whom 87% reported recent tension attributed mainly to academic pressures. From a list of 22 common coping reactions, the students were asked to check those they use to deal with their tensions. The coping responses were also correlated with scores on an assertiveness inventory (AES) and Rotter's Internal-External Locus of Control (I-E) Scale. Reliance on one's own initiatives and turning to significant others were the responses most frequently reported as reactions to tension while seeking professional help was ranked last. Male students more frequently reported using marijuana or seeking sexual comfort than females, while females more frequently reported dysfunctional reactions such as spending endless hours thinking about the problem. The AES correlated significantly with problem-solving approaches. The IE Scale showed internals more inclined to meditate; externals indicated a greater likelihood to seek professional help, fantasize, or drink alcohol.
