Differences in extracurricular activity participation, achievement, and attitudes toward school between ninth-grade students attending junior high school and those attending senior high school

The purpose of this study was to determine the type of school organization that most benefited ninth-grade students. Results indicated that ninth graders in the junior high school setting participated significantly more in extracurricular activities and achieved significantly higher academically than did ninth graders in the senior high school setting.     

Peer-group association and adolescent tobacco use

Mosbach & Leventhal (1988) examined the relation of cigarette smoking to peer-group identification in rural Wisconsin adolescents. They found that among dirts (problem-prone youth), regulars (average youth), hot-shots (good social or academic performers), and jocks (athletes), youth most likely to smoke were dirts and hot-shots. We performed a replication with a Southern California cohort and also for use of smokeless tobacco. We hypothesized that jocks would be the main users of smokeless tobacco. We identified the same groups and an additional one, skaters (skateboarders or surfers). As Mosbach & Leventhal found, cigarettes were used most by dirts. Contrary to their results, but consistent with other research, we found that hot-shots were least likely to smoke. Contrary to our prediction, we found that skaters and dirts were more likely to use smokeless tobacco than were jocks. Our data show that both tobacco forms are used by problem-prone youth.     

Second-Guessing the Jury: Stereotypic and Hindsight Biases in Perceptions of Court Cases1

This research examined the effects of stereotypic beliefs and hindsight biases on perceptions of court cases. Subjects read evidentiary material pertaining to a criminal trial in which the defendant either was a stereotyped offender or was not. Additionally, some subjects were given outcome information about the verdict attained in the trial; half of these subjects were told that the defendant had been found guilty, and the other half were told that he had been found not guilty. The remainder were not given any outcome information. Subjects were than asked to predict the likely outcome of a trial based on the presented evidence. Typical hindsight bias effects were expected and obtained for nonstereotyped offenders; subjects considering these cases viewed the evidence as less incriminating when they were told the defendant had been found not guilty, and they found it to be more incriminating when they were told the defendant had been found guilty, when compared to the no-outcome-information group. However, no hindsight biases were evident in judgments of cases involving stereotyped defendants, who were seen as relatively more likely to be guilty regardless of the nature of outcome information presented. Particularly striking was the lack of impact of the “not guilty” outcome information on perceptions of the guilt of stereotyped defendants. These findings suggest that strong expectations held in foresight may not be amenable to modification in hindsight.     

Predicted and Recommended Behavior of a Woman as a Function of Her Inferred Helplessness in the Dowry and Wife-Beating Predicaments

Two experiments, using hypothetical situations, examined predictions and recommendations regarding a woman's behavior in the dowry and wife-beating predicaments as a function of her perceived helplessness. The dowry experiment described the situation of a stimulus person who has to decide whether to marry a boy under the dowry condition and had a 2 (subject's sex) × 2 (stimulus person's attractiveness) × 2(stimulus person's age) × 3 (stimulus person's socioeconomic status) factorial design, with estimated likelihood of marrying and recommendation to marry as the two dependent measures. The wife-beating experiment described the situation of a battered stimulus person who has to decide whether to leave her violent husband and had a 2 (subject's sex) × 2 (stimulus person's economic independence) × 2 (stimulus person's having children) × 3 (stimulus person's socioeconomic status) factorial design, with estimated likelihood of leaving the husband and recommendation to leave the husband as the two dependent measures. The subjects of the two experiments were undergraduate or graduate students of Bombay University, with 15 subjects per cell in the dowry experiment and 13 subjects per cell in the wife-beating experiment. Female subjects gave a stronger recommendation against marrying under the dowry condition and in favor of leaving the husband than did male subjects. The economically independent women was perceived as more likely to leave the husband than the dependent woman. Results of the wife-beating experiment suggested greater social constraints, under some conditions, on the middle class woman as compared to upper and lower class women in India.     

Temporal learning in 4 1/2- and 6-year-old children: role of instructions and prior knowledge

The present study investigates effects of different types of instructions (high-rate, interval, and minimal) during training with a fixed-interval schedule as a function of prior acquired temporal knowledge. A pretest was used to assess 4 1/2- and 6-year-old children's ability to understand the temporal parameters of a fixed-interval schedule of reinforcement. The results as a whole show that the control exerted by instructions given by the experimenter or elaborated by the subjects themselves on fixed-interval performance of young children depends on the interaction of two factors: development of verbal self-control skills and mastery of knowledge required by the rules forming the instructions.     

Maternal depressed mood and perceptions of child temperament

Research has suggested that women who experience postpartum depression are subsequently more likely to perceive their preschool-aged children as temperamentally difficult and maladjusted. However, previous studies have not controlled for the effects of concurrent depression levels on maternal ratings of child temperament or evaluated the accuracy of maternal reports. In the present study we assessed maternal and paternal ratings of child temperament 2 years after subjects had participated in a study of postpartum depression. The findings indicate that correlations between postpartum depression and subsequent child temperament ratings were accounted for statistically by concurrent levels of depression. Although fathers' ratings corroborated some aspects of maternal perceptions, levels of parental agreement were only moderately high. Moreover, discrepancies between the parents' reports were significantly associated with maternal depression, indicating that parental disagreement is more likely when the wife is dysphoric.     

Contingent reinforcement effects on movement responses of prison inmates to the Holtzman Inkblot Technique

Prison inmates were administered the Holtzman Inkblot Technique (HIT) under conditions of either verbal or nonverbal reinforcement of movement responses. Overall, there were no differences among the verbal, nonverbal, and control groups. Inmates charged with violent crimes were found to give the fewest movement responses. With crime category controlled, more movement responses were given under nonverbal conditions. There were no sex differences for movement responses but testing time increased significantly when administered by the female examiner.     

A comparison of two multidimensional health locus of control instruments

This study examined the factor structure, internal consistency reliability, and construct validity of the multidimensional health locus of control (MHLC) instruments developed by K.A. Wallston, B.S. Wallston, and DeVellis (1978) and Lau (Lau, 1982; Lau & Ware, 1981). Both measures were administered to a sample of Veterans Administration (VA) medical outpatients (N = 181). Only minimal evidence of convergence was found between corresponding scales of the two MHLC instruments. Low convergent validity appears attributable to the poor internal consistency reliability of the Lau-Ware subscales. Moreover, results of factor analysis largely supported the a priori factor structure of the K.A. Wallston et al. (1978) MHLC instrument but failed to support the factor structure of the Lau-Ware instrument. Health locus of control (HLC) dimensions that emerged from simultaneous factor analysis of both instruments were most consistent with a three-dimensional typology (i.e., Personal Control, Professional Control, and Chance) rather than the four-dimensional typology proposed by Lau (Lau, 1982; Lau & Ware, 1981). Implications for HLC conceptualization and measurement are discussed.     

Psychological assessment of catatonic schizophrenia

Probably due to the rarity of the disorder and the general inability of catatonic patients to cooperate with standardized assessment, no data exist documenting the psychological features associated with catatonic schizophrenia that may appear on psychological tests. This study utilized standard assessment techniques to examine clinical hypotheses regarding the psychogenic correlates of catatonic conditions from the performance of one man on psychological tests. In accordance with previous theory, test findings indicated frequent constriction, rigidity, and negativism in conjunction with compulsive traits. Experiences of cognitive and self-fragmentation were juxtaposed with a formal, mechanistic body ego; disorganization and discontinuity were countered with attempts at self-cohesion. Depressed feelings and human interest were apparent, although interpersonal relatedness was frequently characterized by an avoidant, distancing style.
