Attraction and altruism: With a little help from my friends

The present experiment was designed to determine whether the reinforcement value of an altruistic response is a function of attraction toward the victim and/or the affective state of the subject. Subjects (N = 95) received positive or negative evaluations from a victim or from a bystander and subsequently performed an altruistic response which terminated shock delivery to a victim on a series of 14 trials. Analyses of variance indicated that the acquisition of an altruistic response was greatest when attraction toward the victim was most positive (p < .0001) and nonexistent when attraction toward the victim was least positive. The results were consistent with the proposition that attraction rather than affect mediates altruistic reinforcement. Those subjects receiving negative evaluations from the victim failed to acquire the altruistic response, suggesting that failure to help may function as a form of passive aggression.     

Sex differences in preadolescent self-disclosure

Both amount and content of self-disclosure may vary with sex role. Both adult and preadolescent females have been reported as engaging in greater amounts of self-disclosure than males; the present study attempted to replicate these findings with preadolescents, and to investigate sex differences in the content of self-disclosure. A self-disclosure questionnaire covering a wide range of subjects was administered to 307 urban children. The sex difference on the total number of items revealed to a friend closely approached significance, with girls showing greater disclosure. When only intimate content items were examined, the sex difference reached clear significance. Content analysis showed that girls were more willing to reveal items related to emotionality, anxiety, and dependence.     

Private self-consciousness, canned laughter, and responses to humorous stimuli

Sefl-focused attention is hypothesized to (a) intensify emotional responses; (b) diminish susceptibility to suggestion; and (c) increase the consistency of self-report and behavior. These hypotheses were tested by having 82 undergraduates varying in private self-consciousness (PrSC) listen to humorous stimuli presented either with (laugh track group) or without (no laugh track group) canned laughter. Subjects' funniness ratings and overt laughter served as dependent measures. Regression analyses revealed that PrSC and funniness ratings were negatively correlated in the laugh track group, but uncorrelated in the no laugh track group. In contrast, PrSC and overt laughter were positively correlated in both groups. The association between funniness and laughter appeared stronger in high than in low PrSC subjects. Interpreted in light of research indicating that funniness ratings represent affect-free evaluations of humor stimuli, whereas laughter represents amusement, these results suggest that self-focus (a) intensified subjects' amusement; (b) decreased the extent to which their evaluations of the stimuli were biased by canned laughter; and (c) increased the consistency between their (self-reported) cognitive and (overt behavioral) affective responses (although this finding was equivocal).     

Gender differences in math and english achievement: A longitudinal study

This study investigated gender-related developmental trends in math and English achievement as measured by classroom grades and standardized test scores. The sample consisted of 30 males and 30 females followed from 6th through 12th grade. Previous research suggests that developmental trends in male and female achievement may differ as a function of assessment context. Thus, it was hypothesized that female math and English classroom grades would remain stable over time but that achievement test scores in both subject areas would decline. For males, it was hypothesized that performance in both assessment contexts would remain stable. Results confirmed these hypotheses. Results also suggest that school-related responsibility is related to performance in both assessment contexts for females but not for males. The need to consider personal goals when assessing differences in academic ability and performance capabilities is discussed.     

Self-Ratings of Personality: A Naturalistic Comparison of Normative, Ipsative, and Idiothetic Standards

ABSTRACT The purpose of this research is to examine some of the implicit standards that individuals may use when they rate themselves on personality dimensions Specifically, we compared ratings based on instructions that specified normative, ipsative, or idiothetic creteria with ratings obtained when subjects used their own (implicit) standards In a series of three studies, we found that each of the explicit ratings was highly similar to the implicit-standard ratings and that there were substantial individual differences in the relative similarity of each of the explicit ratings to the implicit ratings However, because the normative instructions elicited less extreme responses than any of the other instructions, there was a small but consistent tendency for them to be less similar to the ratings based on implicit standards than the ipsative or idiothetic ratings The implications of this research for personality assessment and self-evaluation are discussed     

Evaluation of self-contained training procedures for the Time-Sample Behavioral Checklist

The comparative effectiveness of two time-limited modes of training observers to code the behavior of clients in residential treatment programs on the Time-Sample Behavioral Checklist (TSBC) was evaluated. The susceptibility of training procedures to consensual observer drift and the predictability of TSBC mastery from trainee characteristics were also examined. Two equated groups of undergraduate students (N=15 each) participated in full-time training on the TSBC and another instrument for 27 days, followed by criterion testingin vivo and on videotapes. One group was trained by experienced personnel using procedures known to be effective but potentially subject to consensual observer drift. The other group was trained using a previously untested set of written and videotape procedures that do not rely on experienced personnel. Comparative effectiveness and observer drift were evaluated by multivariate and univariate ANOVAs on mastery scores reflecting both pattern agreement and level differences between each trainee and criterion codings. The new, more efficient training procedures were found to be as effective as the original training procedures in the degree of mastery achieved by trainees. Original training procedures were found to be resistant to consensual observer drift, with such a phenomenon appearing in only 1 instance of 156 opportunities. The high degree of mastery achieved by trainees during the time-limited training period was comparable to that previously achieved with the original training procedures. No meaningful predictions of coding mastery were found, with only one trainee characteristic being significantly related to one of six mastery criteria. The results document procedures that are both efficient and resistant to invalidity for training observers in the use of multidimensional observational systems, as well as providing guidelines for the development of standardized procedures.This article is based on a thesis submitted to the Graduate College of the University of Illinois at Urbana-Champaign in partial fulfillment of the requirements for the Ph.D. degree in psychology by the first author and under direction of the second author.
