Previous researchers have manipulated forewarning by providing premessage information about the topic and position of the upcoming communication, or the communicator's persuasive intent. Subjects in the present experiment were force-warned either 10 min prior to the communication, or just before the message began of the speaker's topic and position, persuasive intent, or topic only. As hypothesized, forewarning of the communicator's persuasive intent inhibited persuasion regardless of the length of the delay period, but forewarning of the topic and position required a delay in order to confer resistance to subsequent persuasion, suggesting that although both manipulations have been called “forewarning they may lead to reduced persuasion through different mechanisms. Foreknowledge of the source's topic, but not his position also increased resistance to persuasion when followed by a delay period. The results were discussed in terms of both cognitive and motivational mechanisms that may underly the persuasion inhibiting effects of forewarning. 相似文献

The effect of varying trials per day conditions on the CS-US interval or interstimulus interval (ISI) function in rabbit nictitating membrane response conditioning was studied in two experiments. Experiment 1 showed that a 1250-msec ISI was more effective than a 250-msec ISI when there was 1 trial/day. Experiment 2 showed that as the number of trials per day decreased from 20 to 1, the superiority of the 250-msec ISI group over the 1250-msec ISI group declined, with a reversal at 1 trial/day. Results are interpreted in terms of the role of a hypothesized CS-elicited short-duration orienting response in CR performance. 相似文献

Infant rats that were either removed from the nest each day (handled) or left undisturbed (nonhandled) were, in adulthood, given 72 food-reinforced runway acquisition trials followed by 24 trials of extinction training with or without shock. Handled and nonhandled control animals were given runway training without food reinforcement. Reinforced rats ran faster than nonreinforced rats, and handled rats ran faster than nonhandled rats during the initial trials of runway acquisition irrespective of the reinforcement condition. Nonhadled rats stopped running sooner than handled rats when shock was introduced in the goalbox, but differences between handled and nonhandled rats given extinction training without shock were small. Results of a second experiment showed no differences between handled and non-handled rats in the magnitude of the depression effect after an incentive shift. It was concluded that infantile handling had little effect on frustration-motivated behavior, but did affect fear-motivated behavior. 相似文献

Two contradictory hypotheses regarding the effect of self-attention or self-awareness on task performance are considered. Recent research on test anxiety indicates that self-awareness interferes with task performance by decreasing the proportion of attention paid to the task. Wicklund and Duval's (1971) theory of objective self-awareness predicts the opposite: that self-awareness will induce a person to try harder and to perform at a higher level. Experimental evidence indicates that both hypotheses are correct, each at a different level of evaluation. The results are discussed in terms of their implications for a unified social-psychological theory of evaluative self-awareness which could account for findings now classed under separate headings such as test anxiety, self-awareness, and social facilitation. 相似文献

The purpose of this research was to determine the specific behaviors and cues which 104 assessors perceived as indicating the presence of psychological variables shown to be related to competent job behavior. The cue systems utilized were found to be reminiscent of theory Y conceptions of effective job behavior. Implications of the lack of correlation of cue utilization with assessor characteristics are discussed. 相似文献

The intermediate-hue transposition of first- and second-grade children was investigated in two experiments. In Expt. 1, it was found that seriation pretraining increased the amount of far transposition regardless of whether or not the same hues were used in pretraining and subsequent tasks. In Expt. 2, seriation pretraining produced more far transposition than did same-different pretaining and a no-pretraining control. The latter two conditions were not significantly different. Three assumptions about the effects of perceptual pretraining on subsequent transposition were described and related to the data. 相似文献
