Electrophysiological markers of categorical perception of color in 7-month old infants

The origin of color categories has been debated by psychologists, linguists and cognitive scientists for many decades. Here, we present the first electrophysiological evidence for categorical responding to color before color terms are acquired. Event-related potentials were recorded on a visual oddball task in 7-month old infants. Infants were shown frequent presentations of one color (standard) interspersed with infrequent presentations of a color that was either from the same category (within-category deviant) or from a different category (between-category deviant) to the standard. Differences in the event-related potentials elicited by the stimuli were found that were related to the categorical relationship of the standard and the deviant stimuli. The data are discussed in relation to the processes that underlie categorical responding in infancy, as well as the debate about the origin of color categories in language and cognition.     

Fear of success: The influence of sex,sex-role identity,and components of masculinity

Phase I of this experiment was conducted to determine the nature of the relationship between fear of success and sex-role identity. Eighty female and 124 male subjects completed a measure of fear of success (the Sadd Fear of Success Scale, SFOS) and two sex-role scales (the Bem Sex Role Inventory, BSRI; and the Personal Attributes Questionnaire, PAQ). Subjects were subsequently classified by their responses to the BSRI and PAQ as either androgynous, masculine, feminine, or undifferentiated. The results indicated that androgynous and masculine individuals reported less fear of success than feminine or undifferentiated individuals, regardless of their sex. Subsequent analyses revealed that fear of success was more related to the absence of masculine traits than to the presence of feminine traits. Phase II of this investigation was conducted to determine whether a specific component of masculinity was related to the fear of success. The masculinity scales were factor analyzed and factor scores were regressed on the fear-of-success scores. Factor scores reflecting high self-confidence, decisiveness, analyticalness, and independence were related to low levels of fear of success; factor scores reflecting assertiveness, competitiveness, and opinionatedness were not related to the fear of success.     

Behavioral science in medical education: a 1987-1991 bibliography.

Holmes, et al. in 1988 compiled 61 studies in an updated bibliography of behavioral science in undergraduate and graduate medical education. Since then, 64 additional studies of behavioral science in medical education have been published and abstracted in Index Medicus and Psychological Abstracts, the sources for the bibliography.     

Differential recall of successes and failures: Its relationship to defensiveness,achievement motivation,and anxiety

Differential recall of completed and incompleted tasks under high and low stress was studied in 157 Ss. On the basis of repression, it would be expected that Ss identified as hysterics would recall fewer incompletions (ego threatening failures) under high than low stress. The results indicated that hysteria was not related to recall. On the other hand, Ss with high achievement motivation or low anxiety recalled more incompletions under high than low stress while there were no differences in their recall of completions under high and low stress. These results offered no support for repression. Furthermore, the relationships between recall and achievement motivation and anxiety suggest that the differential recall is due to differences in the original learning of the completed and incompleted tasks.     

Effectiveness of debriefing after a stress-producing deception

This experiment was carried out to determine if after deceiving Ss an E had sufficient credibility to effectively debrief the Ss. Ss in two stress groups were given false information indicating that when a signal light came on they would receive painful electric shocks. Ss in a no-stress group were not told about shocks. After being given the threatening instructions, Ss in one of the stress groups were debriefed concerning the deception (but the “shock electrodes” were not removed) while Ss in the other group were not debriefed. After this the signal light came on for all groups. Arousal was measured by pulse rates and self-reports. The results revealed that (a) the instructions about electric shocks increased the arousal levels of the two stress groups relative to the no-stress group, thus indicating that the deception was effective, and (b) after the signal light came on the stress group which had not been debriefed continued to show a high degree of arousal while the stress group which had been debriefed showed a reduction of arousal to the same low level of arousal as the no-stress group, thus indicating that the process of debriefing had been effective.     

The “Friendly visitor” program data: A reply to Denney

Conclusion In summary, Denney's failure to obtain the original results with her reanalyses can be attributed to the fact that she (a) scored some variables differently, (b) included an inappropriate subjects who was not entered into the original analyses, (c) excluded appropriate subjects who were used in the original analyses, (d) included an additional invalid dependent measure previously dicarded, and (e) may have used a different residualization algorithm. In view of these differences, it is not surprising that the multivariate and unvariate results that she obtained were different from those originally reported.We hope that now the procedural differences that account for the inconsistencies alleged by Denney are clear.     

Influence of personal and universal failure on the subsequent performance of persons with type A and type B behavior patterns

We conducted this experiment to compare the task performance of Type A and Type B persons following failure on a task in which no one succeeded (universal failure) versus failure on a task in which others had succeeded (personal failure). Postfailure performance was measured in terms of speed of completion of anagrams. Initial analyses indicated that the failure manipulation was effective in influencing the subjects' perceived cause of their failures, and that subjects were more anxious and depressed following personal failure than universal failure. More important, we found that Type A subjects performed better following personal rather than universal failure, whereas type of failure had no effect on the performance of Type B subjects. The results suggest that contrary to what is usually thought, Type A persons do not struggle for success indiscriminately. The results are discussed in terms of need for control and self-esteem.
