Physical/verbal aggression: Sex differences in style1

Two studies exploring the use of physical/verbal aggression are reported, the first using women and the second using men as subjects. Both studies allowed subjects to choose between and control the intensity of two response modes: verbal aggression (insults) and physical aggression (electric shock). Aggressive style was investigated over two levels of arousal, sex of experimenter, and sex of provocateur-victim. Results indicated that women aggressed discriminatively in the verbal mode as a function of their arousal, while men were capable of aggressing discriminatively in both the verbal and physical modes. Men who had been disagreed with and punished by a female victim-provocateur in the presence of a male experimenter or by a male victim in the presence of a female experimenter demonstrated high levels of physical aggression compared to the other groups.     

General guidelines for conducting behavior modification programs in public school settings

Tentative guidelines for initiating behavior modification programs are presented. Discussion focuses on the importance of initial introduction of these procedures to teachers, the relation of teacher personality variables to technique selection, factors to consider when evaluating children for modification, and suggestions for on-going participation and withdrawal of the psychologist as an active agent in such programs.     

Reliability of laterality effects in a dichotic listening task with words and syllables

Large and reliable laterality effects have been found using a dichotic target detection task in a recent experiment using word stimuli pronounced with an emotional component. The present study tested the hypothesis that the magnitude and reliability of the laterality effects would increase with the removal of the emotional component and variations in word frequency. Thirty-two participants completed both a dichotic syllable detection task and a dichotic word detection task. In both tasks, stimuli were pronounced in a neutral tone of voice. Each task was completed twice to allow the estimation of test-retest reliability. Results failed to confirm the hypothesis since they were generally similar to those obtained in the previous study. A significant right ear advantage (REA) was found only with the word task. Although no ear advantage was found for the syllable task, somewhat better reliability was demonstrated compared to that obtained with words. The present findings suggest that including an emotional component does not reduce the reliability or magnitude of auditory laterality effects. In fact, the emotional component may have forced participants to focus on the language aspects of the stimuli. This might partly account for the reduced reliability in words and the absence of REA in syllables. Motivational factors inherent to the within-subject design used here are also discussed.     

Attractiveness and Income for Men and Women in Management1

It is commonly believed that attractive people are more successful, but the empirical support for this belief is mixed. A number of role-playing, laboratory studies have demonstrated that more attractive men are more often hired, but the laboratory data for women are less consistent. Few studies have explored the effects of attractiveness on actual hiring and starting salaries for men or women. Even less work has been done on the impact of attractiveness once on the job. It was predicted that there would be positive effects for attractiveness and that the effects would be stronger as people worked longer on their jobs. To test this prediction, a sample of 737 male and female MBA graduates from the years between 1973 and 1982 was used to explore how facial attractiveness relates to starting and later salaries. Results indicated that more attractive men had higher starting salaries and they continued to earn more over time. For women, there was no effect of attractiveness for starting salaries, but more attractive women earned more later on in their jobs. By 1983, men were found to earn $2600 more on the average for each unit of attractiveness (on a 5-point scale) and women earned $2150 more. Implications for research in this area are discussed.     

Temporal learning in random control procedures

Experiments 1 and 2 delivered conditioned stimuli (CSs) at random times and unconditioned stimuli (USs) at either fixed (Experiment 1) or random (Experiment 2) intervals. In Experiment 3, CS duration was manipulated, and US deliveries occurred at random during the background. In all 3 experiments, the mean rate of responding (head entries into the food cup) in the background was determined by the mean US-US interval, and the mean rate during the CS was a linear combination of responding controlled by the mean US-US and mean CS onset-US intervals; the pattern of responding in time was determined by the interval distribution form (fixed or random). An event-based timing account, Packet theory, provided an explanation of the results.     

Brief Report- Adults' Freely Produced Emotion Labels for Babies' Spontaneous Facial Expressions

English-speaking Canadian, Cantonese-speaking Hong Kong Chinese, and Japanese speaking Japanese adults were shown 13 still photographs of the facial expressions of Chinese babies subjected to various emotion-elicitation procedures. Some respondents were asked to give an emotion label of their choice for each photograph, others to judge its pleasant-unpleasant quality. Only facial expressions taken during the “happy”; condition showed agreement by a majority across all three cultural samples on a specific basic emotion. Agreement on the pleasant-unpleasant quality of the baby's expressions was higher, but still varied with culture.
