Supportive and problematic social interactions: A social network analysis

Assessed the number of sources of supportive and problematic social interactions in the total social network as well as the number who were the sources of consistently supportive or problematic interactions in a sample of 2nd year medical students. Number of problematic interaction sources was hypothesized to be more predictive of psychological and physical well-being than number of supportive interaction sources. Results showed that total supportive and total problematic interaction sources were equally predictive of life satisfaction. The presence of at least one individual who is a consistent source of problematic interactions was most predictive of lower life satisfaction. Results indicate the importance of studying both supportive and problematic social interactions. They also suggest that interactions with individuals that are consistently problematic may negatively impact upon well-being.     

Working through: 1914-1984

This paper reviews the various meanings given to "working through" by Freud and others. The relation of "working through" to "analysis" is discussed and illustrated.     

Optimism and coping as determinants of psychosocial adjustment to rheumatoid arthritis

Psychosocial adjustment in 66 patients with chronic rheumatoid arthritis, with a mean duration of 12 years with the disease, were evaluated in a prospective design, with 62% of the sample followed up 16 months later. It was predicted that dispositional optimism would predict adjustment over time and that perceived support and perceived control would be related to psychosocial adjustment at the time of concurrent measurement. At Time 1, psychosocial adjustment was associated with greater optimism and perceived support and less disability. Optimism at Time 1 was the only significant predictor of changes in adjustment at Time 2 controlling for Time 1 adjustment and Time 2 disability. It was found that optimism temporally precedes increases in psychosocial adjustment. In terms of coping strategies, wishful thinking was related to poorer social adjustment, whereas problem-focused coping was marginally related to positive adjustment. Neither coping strategy predicted adjustment across time. Optimism at Time 1 did predict problem-focused coping at Time 2. Perceived social support regarding a specific circumstance at a given point in time enables one to persist in solving a task. Interventions to enhance the quality of life of individuals coping with progressive deteriorative disease must look at the influence of their behavior and attitude on those who provide care for them.     

Sparing and recovery of function in spinal larval frogs (Rana catesbeiana): effect of level of transection.

Bullfrog tadpoles with cervical or midthoracic transection of the spinal cord were allowed to recover for 5 weeks, at which time axonal growth across the transection site was assessed by transport of horseradish peroxidase. Weekly behavioral tests included those for posture, spontaneous locomotion, cutaneously elicited swimming, and intersegmental coordination. Behavioral and electrophysiological assessments suggest that behavioral recovery depends, at least in part, on the growth of fibers across the transection site. Anatomical and behavioral recovery does not appear to differ with the level of spinal transection, but there was greater sparing of posture, spontaneous locomotion, and stimulus-induced locomotion in tadpoles with thoracic transection of the spinal cords.     

Multiple anchoring of category rating scales

A psychophysical experiment compared the effects of two different kinds of anchoring upon category ratings of the sizes of squares: (1) single anchoring in which the same square was presented on every anchoring trial, and (2) multiple anchoring in which squares of different sizes were presented on anchoring trials. Subjects did not rate the anchors, only those squares presented on alternate trials as the series stimuli. The major finding was that the two kinds of anchoring have similar effects. As with the single anchor, the multiple anchor establishes a new endpoint for the scale of judgment. The previously demonstrated relationship of increasing and then decreasing contrast as a function of the remoteness of the single anchor (Sarris, 1967, 1976) was found also for multiple anchoring.     

The components of psychic conflict and its consequences in mental life.

This paper surveys current psychoanalytic concepts of drives, unpleasure related to drives, defense and compromise formation, with special attention to the author's contributions to each subject during the years 1950-1978.     

On the evaluation of one-sided evidence

We examine predictions and judgments of confidence based on one-sided evidence. Some subjects saw arguments for only one side of a legal dispute while other subjects (called ‘jurors’) saw arguments for both sides. Subjects predicted the number of jurors who favored the plaintiff in each case. Subjects who saw only one side made predictions that were biased in favor of that side. Furthermore, they were more confident but generally less accurate than subjects who saw both sides. The results indicate that people do not compensate sufficiently for missing information even when it is painfully obvious that the information available to them is incomplete. A simple manipulation that required subjects to evaluate the relative strength of the opponent's side greatly reduced the tendency to underweigh missing evidence.
