Mood-induced changes on the Implicit Association Test in recovered depressed patients

A mood induction paradigm was used to examine dysphoria-related changes in two types of cognitive processing in individuals who had previously experienced depression. Formerly depressed patients (n = 23) and never-depressed controls (n = 27) completed the Dysfunctional Attitudes Scale, a self-report measure of effortful processing, and performed the Implicit Association Test, an automatic-reaction time task that measures evaluative bias, before and after a negative-mood induction. The formerly depressed group showed both an increase in endorsement of dysfunctional attitudes and a more negative evaluative bias for self-relevant information after the induction, relative to controls--however, there was no association between the mood-linked changes observed on these two measures. The shift in evaluative bias shown by the formerly depressed group was similar to that seen in a group of 32 currently depressed individuals. These findings suggest that even a mild negative mood in formerly depressed individuals can reinstate some of the cognitive features observed in depression itself.     

Haptics and projection: drawings by Tracy, a blind adult

Outline drawings in a raised form were made by a blind woman, Tracy, who has been blind from very early in life. Highly practiced in drawing, she reports she is largely self-taught. To invoke matters of projection, she was asked to represent an object with faces slanting away from the observer, a fixed array from different vantage points, and sets of objects in depth. In particular, she drew a cube balanced on a vertex, three objects from different vantage points, receding rows of glasses, and a house. Her drawings included features of parallel and polar projection. Her use of these features may reflect an appreciation of direction from a vantage point, which observers deal with via haptics in everyday tasks. Tracy may have advanced drawing-development skills common to the blind and the sighted.     

Immediate breast reconstruction and psychological adjustment in women who have undergone surgery for breast cancer: a preliminary study

Current debate exists regarding the timing of reconstructive surgery following mastectomy for breast cancer, with research pointing in favour of immediate reconstruction. This cross-sectional study sought to compare the psychological outcome of breast cancer treatment in women who had either received mastectomy and immediate reconstruction using autogenous tissue (n?=?30), or mastectomy alone (n?=?34), and also determine adjustment factors in this population as a whole. Participants completed measures of depression, anxiety, body image, self-esteem, coping and perceived social support at a time point 3?-?15 months after initial surgery. No significant differences were revealed between the two groups on any of the outcome measures. Poor body image, low self-esteem, and a tendency to use coping strategies characterized by helpless/hopelessness and anxious preoccupation, rather than fighting spirit, were highly predictive of distress. Reasons for the lack of differences between the two groups are explored.     

Evaluation of an individualized treatment program for adolescent shoplifters

This paper evaluates an individualized treatment program for adolescent shoplifters. Two hundred eighty-six juveniles charged with shoplifting were randomly assigned to treatment and control groups. Treatment contracts included combinations of fines, community service, monetary restitution, written essays, anti-shoplifting videos, apology letters, and individual and/or family counseling. Results revealed that 88% of the treatment group fully completed their treatment contracts. Furthermore, following intervention, the treatment group was rated significantly higher than the control group on personal responsibility and significantly lower on the likelihood of recidivism. Finally, compared to the control group, the treatment group displayed significantly less recidivism over a two-year follow-up period. Regression analyses revealed that several at-risk background variables were significantly associated with less successful treatment outcomes.     

Variable-interval reinforcement schedule value influences responding following REM sleep deprivation

The effects of rapid-eye movement sleep deprivation (REMSD) in rats were studied in relation to variable-interval (VI) reinforcement schedule value. Initially, lever pressing was maintained on a VI 30-s schedule of food pellet delivery. After a baseline was established, rats were repeatedly exposed to 96 hr of REMSD and control conditions of an equivalent duration. Responding decreased following REMSD but not after exposure to control conditions. Lever pressing was then maintained on a VI 15-s schedule of food pellet delivery and exposure to the REMSD and control conditions was repeated. Under this condition following repeated REMSD exposures, rates of lever pressing became similar to baseline responding. A VI 30-s schedule of food pellet delivery was then reinstated and REMSD and control conditions were repeated. Lever pressing following exposure to the REMSD condition decreased for 3 of 4 rats. Results suggest that VI schedule value influences the effects of REMSD on responding.     

The invalidity of disclaimers about the effects of social feedback on self-esteem

Despite the fact that several theories suggest that people's self-esteem is affected by social approval and disapproval, many individuals steadfastly maintain that how other people regard them has no effect on how they feel about themselves. To examine the validity of these beliefs, two experiments compared the effects of social approval and disapproval on participants who had indicated either that their self-esteem is affected by how other people evaluate them or that their self-esteem is unaffected by interpersonal evaluation. Results of both studies converged to show that approval and disapproval clearly affected the self-esteem of even those individuals who denied that social evaluations affected their feelings about themselves.     

Development of an abstract category representation for the spatial relation between in 6- to 10-month-old infants

Nine experiments examined the formation of an abstract category representation for the spatial relation between by 6- to 10-month-old infants. The experiments determined that 9- to 10-month-olds, but not 6- to 7-month-olds, could form an abstract category representation for between when performing in an object-variation version of the between categorization task. The results also demonstrated that 6- to 7-month-olds could form category representations for between in the object-variation version of the between categorization task but that such representations were specific to the particular objects presented. The evidence confirms that representations for different spatial relations emerge at different points during development, and suggests that each representation undergoes its own period of development from concrete to abstract.     

Effects of sleep deprivation on free-operant avoidance

Two studies examined effects of sleep deprivation on free-operant avoidance by rats. In Experiment 1, a 5-s shock-shock (SS) interval and 20-s response-shock (RS) interval produced baseline performances, which were reestablished after each experimental manipulation. Once baselines were established, animals were exposed to 24, 48, or 96 hr of sleep deprivation and equivalent periods of home cage and food restriction as a control condition. Compared to baseline, sleep deprivation increased response rates by increasing the proportion of brief interresponse times (IRTs); response rates changed little in the control conditions. Percentage of shocks avoided did not systematically change across conditions. In Experiment 2, the RS interval was manipulated (10, 20, and 40 s), while the SS interval (5 s) and level of sleep deprivation (48 hr) were held constant. Across RS intervals, sleep deprivation increased response rates via a shift toward brief IRTs. In addition, sleep deprivation increased the percentage of shocks avoided as an inverse function of RS intervals.
