Date of correction: July 16, 2010 Reason for correction: - Correction: ABSTRACT Details: Wrong : The purpose of this study was to investigate a mediating function of hostility for overt aggression. It was hypothesized that hostile persons would respond more readily to aggressive stimuli than to friendly ones delivered by other persons.
Twenty-one High-hostility subjects and 21 Low-hostility subjects, selected from 90 male college students based on two scales (Suspicion and Resentment) from the Buss-Durkee Inventory, were introduced into the experimental situation of a competitive nature: If a subject showed a faster reaction time on a given trial than his opponent (an experimental confederate), he became a shocker and delivered one of five intensity levels of electric shock to the opponent. If the opponent showed a faster reaction time, he became a shocker. Sixty trials, equally divided into three blocks, were administered to each subject. The subjects were assigned to one of three experimental conditions: Aggressive, Friendly, or Neutral. In the Agressive condition, shock intensities set by the opponent against the subject became gradually stronger as the trial block advanced, while in the Friendly condition, they became weaker. There were no consistent changes in shock strength in the Neutral condition. Dependent measures were intensity and duration of the shocks delivered by subject and the product of the two. The subject's rate of wins was fixed at 50%.
The major findings were as follows: (a) Non-hostile subjects delivered stronger shocks to the aggressive opponents and weaker shocks to the friendly ones. However, hostile subjects failed to vary their shock level regardless of the changes in the opponents. (b) Hostile subjects delivered longer shocks to the aggressive opponent while non-hostile subjects did not. (c) Non-hostile subjects delivered electric shocks aggressively to the aggressive opponent in terms of shock energy as defined by intensity×duration, while they delivered shocks friendlily to the friendly opponent. On the other hand, hostile subjects also responded aggressively to the aggressive opponent but they did not respond friendlily to the friendly opponent.
It was suggested that hostile persons, unlike non-hostile ones, can not respond friendlily to friendly others, and that they tend to use an indirect means such as duration of shock in aggressing others. This tendency would seem to reflect their suspiciousness and tendency to deceive others.
Right : It was hypothesized that a hostile person would respond more readily to aggressive stimuli than to friendly ones delivered to him from other persons. Hostile and non-hostile subjects were selected from male college students based on the Buss-Durkee Inventory. Subjects were given opportunites to deliver electric shocks against their opponents (confederates) on trials competing for reaction time. Measures of their aggression were intensity, duration of shocks and their product. The results showed that non-hostile subjects responded aggressively to the aggressive opponent and friendlily to the friendly opponent, and that hostile subjects responded aggressively to the aggressive opponent without responding friendlily to the friendly opponent.

Abstract

It was hypothesized that a hostile person would respond more readily to aggressive stimuli than to friendly ones delivered to him from other persons. Hostile and non-hostile subjects were selected from male college students based on the Buss-Durkee Inventory. Subjects were given opportunites to deliver electric shocks against their opponents (confederates) on trials competing for reaction time. Measures of their aggression were intensity, duration of shocks and their product. The results showed that non-hostile subjects responded aggressively to the aggressive opponent and friendlily to the friendly opponent, and that hostile subjects responded aggressively to the aggressive opponent without responding friendlily to the friendly opponent.
