Deviant behaviors in rural elementary schoolchildren

A sample of 1567 third- and fourth-grade children in rural Illinois were rated on the Behavior Problem Checklist. The mean frequency of conduct problems, inadequacy-immaturity, personality problems, and socialized delinquency were analyzed by grade, sex, and age. Fourth graders and older children tended to have more problems than did third graders and younger children. Boys had more problems than did girls except on the personality-problem dimension.     

Attention,brightness contrast,and assimilation: The influence of relative area

A model of information transmission in the visual system which describes the effect of attention on apparent brightness is examined. This model states in part that the luminance of the portion of the visual field which captures the attention is overweighted in arriving at an overall average luminance level across the visual field. As this average must be computed with respect to both luminance and relative area, it is hypothesized that increasing the relative area of the portion of the visual field that captures the attention will result in a greater effect on the apparent brightness of all parts of the visual field. Two predictions, which involve the effect of relative area on apparent brightness, are experimentally tested and confirmed.     

The computer as experimenter in social psychological research

The effects of familiarity and exposure paradigm on evaluative meaning were investigated in four experiments involving 161 Ss. A DEC PDP-10 computer linked to a VB10-C display screen for 1/0 assigned Ss to condition, presented instructions, tested Ss’ understanding of the instructions, generated and displayed stimuli in various frequencies, and obtained evaluative ratings of the stimuli. Problems encountered, Ss’ reactions, and current and possible use of the computer in social psychological research are discussed.     

A review of behavioral approaches to weight control

Forty case reports and experimental studies of behavioral approaches to weight control were reviewed. The treatments, categorized as: aversive conditioning, covert sensitization, coverant conditioning, therapist controlled reinforcement and self-control of eating, were evaluated in terms of their empirical support. It was suggested that self-control procedures may be the most promising treatment, particularly when used in conjunction with therapist controlled reinforcement. Methodological difficulties and implications for future research were discussed.
