Violent groups

This article reviews relevant empirical studies and theoretical formulations in an effort to gain insight into the many violenceprone groups that have come to public attention in recent years. Research findings show group members tend to score high on variables like anger at family members and overcontrolled hostility, often are in developmental transition at the time they join the groups, and gain relief from significant emotional distress through group membership. Leader characteristics, group norm forming and group control processes particular to these kinds of groups are also described in an effort to develop further understanding.Parts of this paper were presented in New York City at a September 1979 symposium on forensic psychology and psychiatry sponsored by the New York Academy of Science.     

Frequency of measurement and data utilization as factors in standardized behavioral assessment of academic skill

A study was conducted to investigate the effects on students' spelling achievement of variations in teacher assessment procedures. Teachers measured student spelling performance at a constant level of task difficulty using different measurement frequencies and different rules to interpret the data. Each teacher wrote two consecutive 3-week goals for improved spelling performance for two sets of 100 spelling words and then measured student performance either daily or weekly by dictating randomly selected words from each 100-word list. Teachers were trained to apply either a predetermined set of decision rules or their own judgment to the data to decide if the spelling program they had implemented for the student was effective. Ineffective programs were changed or modified. Results indicated that daily measurement was significantly more effective than weekly measurement in increasing spelling achievement and that, under certain conditions, decision rules were more effective than teacher judgment in determining when to make program changes or modifications.This research was conducted pursuant to Contract 300-77-0491 between the Bureau of Education for the Handicapped (now called Special Education Programs) and the University of Minnesota Institute for Research on Learning Disabilities.     

Employee self-esteem: A review of the literature

Theories and empirical findings about self-esteem derived from the work role and its activities are reviewed. First, self-esteem is defined and problems inherent in its measurement are discussed. Theoretical perspectives relating self-esteem to the work role and activities are then outlined. Problems of a methodological nature, common to most of the evidence, are highlighted prior to reviewing the intrinsic and extrinsic job characteristics which influence self-esteem. The evidence pertaining to the moderating effects of chronic global self-esteem on such relationships is incorporated. The attitudinal and behavioral correlates of high employee self-esteem are then presented, followed by the influence of chronic self-esteem level on occupational choice. Suggestions are made for future research in line with the methodological and conceptual problems encountered.     

The overjustification effect

After reviewing the literature on overjustification (defined as any situation in which an external reinforcer is tied to an activity that would have been performed without that reinforcer), it was concluded that reattribution cannot adequately account for response decrements following the removal of reinforcers. An alternative explanation was proposed involving the concept of “reward contrast,” in which it is argued that individuals compare their actual or expected outcomes following a response with previous outcomes. When this comparison is favorable, the response is strengthened; when unfavorable, the response is weakened. Based upon the notion of reward contrast, an experiment was performed in which 16 albino rats were permitted to wheel-run for 33 days. After 11 acquisition and 5 baseline days, rats in the experimental group were reinforced for running at their baseline rate, while control rats continued to run for no reinforcement. Following 5 days of reinforcement, experimental animals were put into extinction. As hypothesized, albino rats displayed typical over-justification effects during extinction. As also hypothesized, these effects were temporary, with a gradual return to baseline over repeated extinction trials.     

The socialization of sex-differentiated skills and academic performance: A mediational model

Using a multifactorial model, sex differences in academic performance were examined in a sample of 347 elementary school children. As expected, girls' academic performance averaged higher than boys'. Path analysis confirmed initial hypotheses that girls' advantage is partially due to their characteristic of greater responsiveness to social cues and compliance with adult direction. This advantage was partially offset in this model by boys' greater visual-spatial skill, which also was a predictor of academic success. Access to stereotypic masculine toys and activities at home was, for both sexes, a predictor of children's visual-spatial ability. As expected, socioeconomic variables, including mothers' occupation and fathers' level of education, also influenced the environmental, social, and cognitive factors predicting academic success. These results indicate that boys' and girls' differential development of specific cognitive and social skills may play an important role in establishing sex differences in academic performance.     

Gendered Reason: Sex Metaphor and Conceptions of Reason

Reason has regularly been portrayed and understood in terms of images and metaphors that involve the exclusion or denigration of some element—body, passion, nature, instinct—that is cast as “feminine.” Drawing upon philosophical insight into metaphor, I examine the impact of this gendering of reason. I argue that our conceptions of mind, reason, unreason, female, and male have been distorted. The politics of “rational” discourse has been set up in ways that still subtly but powerfully inhibit the voice and agency of women.
