Cognitive biases in the perception of discrimination: The importance of format

Previous work has shown that people seem less able to perceive sex discrimination on a personal level than on a societal level. The present experiment was performed to test the hypothesis that this phenomenon is in part an information-processing bias; that is, the perception of discrimination is more difficult when one makes case-by-case comparisons than when one encounters information in aggregate form. The experiment demonstrated the importance of formatting for the perception of discrimination. Among subjects with little or no emotional investment in the issue of sex discrimination, the format of the pertinent information has a large effect on information processing: subjects perceived less discrimination when they encountered the relevant information in little chunks than when they saw the total picture at a single shot.     

Client-therapist intimacy: responses of psychotherapy clients to a consumer-oriented brochure

Psychotherapy clients read two consumer-oriented brochures: a general brochure on psychology and a brochure on the topic of client-therapist intimacy. Half of the participants read the general brochure first and the brochure on client-therapist intimacy second, and half the participants did the reverse. Participants reported favorable reactions to the brochures, indicating they thought both should be made available to psychotherapy clients; that neither were too long, too sensitive, or too difficult to read; and that the brochures should be made available early during the therapeutic process. After reading the client-therapist intimacy brochure, participants also showed some changes in Likert-type scores measuring attitudes regarding intimate contact between clients and therapists. Although participants were more negative about issues of sexual misconduct after reading the client-therapist intimacy brochure, they did not indicate a decrease in trust of therapists, nor did they indicate a greater likelihood of filing a false complaint. We concluded that therapists' reservations about presenting clients with factual information regarding therapist sexual exploitation of clients are not empirically founded.     

PERCEPTIONS OF BEHAVIORAL CONSISTENCY:

Abstract— Actors view behavior relevant for personality traits as more variable than observers do. This study was designed in replicate this actor-observer effect (AOE) in a common-target paradigm, test whether actors, observers, or both are intuitively aware of the AOE, and examine the effects of social projection on people's awareness of the AOE. Within each actor-observer pair, subjects described the actor on a series of trait adjectives and rated the consistency of relevant behavior. They then predicted the other person's ratings. The AOE emerged, and actors, but not observers, were aware of the effect On average, actors correctly predicted that observers rated actors' behavior as more consistent than actors themselves did Correlational analyses showed that actors and observers were equally prone to project their own ratings lo their matched partners     

Synelfin Regulation during the Critical Period for Song Learning in Normal and Isolated Juvenile Zebra Finches

Male zebra finches (Taeniopygia guttata) learn to sing during a critical period in adolescence. We previously described a presynaptic protein, synelfin, whose mRNA is increased early in this critical period in a brain nucleus specifically implicated in song learning, lateral MAN (lMAN). In the current study, in situ hybridization was used to map this change in gene expression to the subregion of lMAN that projects to the robust nucleus of the archistriatum (RA), the principal motor output of the telencephalic circuit that controls song production. Using confocal immunofluorescence microscopy, we detected numerous puncta of synelfin immunoreactivity that apparently represent presynaptic terminals from lMAN in the RA of young males. Synelfin immunoreactivity in RA declined abruptly between 40 and 45 days of age, a time of major synaptic reorganization in RA. This change did not occur until about 10 days after the decline in synelfin mRNA in cell bodies within lMAN, indicating a relatively slow turnover of the protein in presynaptic terminals and suggesting that some of the functional changes that occur during the critical period may arise from regulatory decisions that were initiated a week or more earlier. Depriving birds of tutoring did not halt or delay the decline of synelfin mRNA in lMAN. This change in gene expression must not be a consequence of early song learning, but may reflect an innate or programmed step in song circuit development.     

Perceptual learning in visual category acquisition

The attribute structure of a set of dot patterns was studied by having subjects segment (parse) the dots of each pattern into parts or subunits by drawing circles around groups of dots from each pattern. These parsing data were obtained for subjects who had no prior experience with the patterns and for subjects who had previously learned to identify the patterns as members of one of four categories. Analyses of the parsing data indicated that category learning increased the salience of large subunits that were similar in orientation for patterns that were members of the same category. This evidence for perceptual learning was obtained even when the category training procedure required learning to identify the patterns individually, suggesting that attribute abstraction and item learning are not incompatible. It was also obtained without an increase in overall intersubject agreement. The latter result led us to question the usefulness of intersubject agreement as an index of category knowledge.     

VISUO-PERCEPTIVE AND VISUO-MOTOR PERFORMANCE OF CHILDREN WITH READING DISABILITIES

N ielsen , H. H. & R inge , K. Visuo-perceptive and visuo-motor performance of children with reading disabilities. Scand. J. Psychol ., 1969, 10 , 225–231.—Twenty 9–10-year-old children with reading disability were compared with twenty normal readers on Frostig Test of Visual Perception, Bender Visual Motor Gestalt Test and Goodenough Draw-a-Person Test. Contrary to prediction, the results showed more similarity than difference in performance level between the two groups, only the Bender Test discriminating significantly ( p<0.05 ). It was concluded that impaired visual perception and visuo-motor dysfunction did not seem important correlates of reading disability.     

Stress-related immune changes in middle-aged and older women: 1-year consistency of individual differences.

This study reviews prior research and reports longer-term consistency of stress-related immune variables in middle-aged and older women who performed mental math and speech tasks 2 times 1 year apart. Leukocyte subsets, mitogen-induced lymphocyte proliferation, and natural killer cell activity were measured at baseline, after tasks, and after 30-min recovery. Epstein-Barr virus (EBV) antibody titers were assessed at baseline. Pearson coefficients and standardized maximum-likelihood estimates of year-to-year covariances for leukocyte subsets and EBV titers showed moderately high to high baseline and posttask consistency and lower recovery consistency; consistency for other functional immune assays and reactivity scores for all variables was moderate to low. Results support longitudinal study of psychosocial context effects on tonic immune function and posttask scores.
