Fifth-grade and kindergarten boys and girls were exposed to a violent televised episode that was introduced as a fictional portrayal (fantasy condition) or as a news broadcast (reality condition). Additional groups were given no information (no-instructional-set condition) about the violent stimulus or were not exposed to the violent episode (no-TV condition). Aggressive responses and helping responses were recorded immediately following exposure. Boys were most aggressive in the reality and no-TV conditions. They were less aggressive in the noinstructional-set condition and least aggressive in the fantasy condition. In almost direct contrast, girls were most aggressive in the fantasy and no-instructional-set conditions and least aggressive in the reality and no-TV conditions. A posteriori analyses of this interaction effect revealed that girls were less aggressive than boys in the no-TV condition and in the reality condition, but not in the fantasy condition nor the no-instructional-set condition. These effects held for both older and younger children.  相似文献

Models of speech processing typically assume that speech is represented by a succession of codes. In this paper we argue for the psychological validity of a prelexical (phonetic) code and for a postlexical (phonological) code. Whereas phonetic codes are computed directly from an analysis of input acoustic information, phonological codes are derived from information made available subsequent to the perception of higher order (word) units. The results of four experiments described here indicate that listeners can gain access to, or identify, entities at both of these levels. In these studies listeners were presented with sentences and were asked to respond when a particular word-initial target phoneme was detected (phoneme monitoring). In the first three experiments speed of lexical access was manipulated by varying the lexical status (word/nonword) or frequency (high/low) of a word in the critical sentences. Reaction times (RTs) to target phonemes were unaffected by these variables when the target phoneme was on the manipulated word. On the other hand, RTs were substantially affected when the target-bearing word was immediately after the manipulated word. These studies demonstrate that listeners can respond to the prelexical phonetic code. Experiment IV manipulated the transitional probability (high/low) of the target-bearing word and the comprehension test administered to subjects. The results suggest that listeners are more likely to respond to the postlexical phonological code when contextual constraints are present. The comprehension tests did not appear to affect the code to which listeners responded. A “Dual Code” hypothesis is presented to account for the reported findings. According to this hypothesis, listeners can respond to either the phonetic or the phonological code, and various factors (e.g., contextual constraints, memory load, clarity of the input speech signal) influence in predictable ways the code that will be responded to. The Dual Code hypothesis is also used to account for and integrate data gathered with other experimental tasks and to make predictions about the outcome of further studies.  相似文献

Middle- and lower-class children who had been treated by E in a warm or aloof manner were given a discrimination learning task under one of six conditions forming a 3 × 2 design: three reinforcement types (Verbalintoned, Verbal-nonintoned, or Symbolic) and reinforcement for correct or incorrect responses. In accordance with Zigler's valence theory of social reinforcement, lower-class girls and middle-class children of both sexes tended to perform better when they had previously received warm treatment. No significant differences among the three types of reinforcers occurred in either SE group, thus failing to support the implications of several theories about the relative effectiveness of social and nonsocial reinforcers and tonality factors related to SES.  相似文献

Selective exposure as a reaction to cognitive dissonance has long eluded researchers working in the realm of dissonance theory. It is proposed here that the difficulties in selective exposure paradigms have resulted from inadequate designs, and more particularly, it is likely that many of the previous findings are due to confoundings. The present experiment manipulates the variable of choice with the intent of controlling for a variety of possible confounds. The experiment shows a simple, theoretically predicted effect: Selective exposure, favoring supporting over nonsupporting information, increases to the degree that an onerous task is undertaken with volition.  相似文献

Two experiments were conducted to examine the relationship between stress level and learned helplessness in human subjects. Experiment I subjected subjects to loud or moderate noise in order to induce differential stress. Half of the subjects within each stress group were unable to escape from a series of noise bursts, whereas the other half could terminate each burst by manipulating appropriate switches. After the pretreatment series, the same noise was again delivered to subjects, all of whom could now escape or avoid noise by making an appropriate response on a shuttle box. Inescapable (helplessness) pretreatment interfered with escape learning in the second (test) phase of the study under both levels of stress. Experiment II was a partial replication of the first study using only loud noise. The interference effect during test trials was greater than in the first study. In addition to these findings, measures of a coronary-prone behavior pattern were related to differential susceptibility to the interference effect under both high stress and moderate stress conditions. These results were interpreted in terms of differing perceptions of threat imposed by lack of environmental control.  相似文献

One hundred and twenty-five college students rated a total of 74 jokes, chosen by stratified sampling, on funniness and on 13 other scales suggested by humor theories. Highly similar factor structures were found with two sets of jokes. Ratings of surprise, resolution, and originality correlated strongly with funniness and helped define a factor on which funniness ratings loaded. Scales pertaining to painfulness, anxiety, or importance of joke topic were positively correlated with funniness but defined a factor essentially independent of it. Partial correlations suggested that these scales were related to funniness through their common relationship with incongruity and resolution scales. Ratings of how much a joke made subjects “feel free” correlated much more highly with ratings of incongruity and resolution than with ratings of painfulness, anxiety, or importance of joke topic. Results were interpreted as providing support for an incongruity-resolution theory of humor, and for the interdependency of affective factors with incongruity-resolution mechanisms.  相似文献

The present investigation sought to identify personality correlates of occupational status. Because occupational status is a direct function of occupation, the relationship between personality and status was examined both within and across occupational groups using Holland's 1973 typology. Four two-way analyses of covariance of 16PF (Sixteen Personality Factor Questionnaire, Form A) second-order personality factors were performed using data from 175 employed adult males. No single personality factor was associated with status across occupational types. Among Social occupations, the low-status group had higher Extraversion and lower Anxiety scores than the high-status group. In general, the relationship between personality factors and occupational types provided additional confirmation of Holland's theory using an employed adult sample.  相似文献

Decrements in taste-aversion learning produced by extensions of the interval between the CS flavor and poisoning (the US) may be attributed to decay of the CS trace during long CS-US intervals. Kalat and Rozin (1973) alternatively proposed that such decrements occur because during extended CS-US intervals subjects learn that the CS is safe. They sought to show that trace decay is not responsible for the CS-US delay gradient by demonstrating that learning is disrupted even if the CS is reintroduced during extended CS-US intervals. The present experiments show that such a second CS presentation during conditioning may (1) enhance subsequent intakes of the CS solution whether or not subjects are poisoned, and/or (2) facilitate aversion learning, the facilitation being greater the closer the second CS exposure is to poisoning. These results question the adequacy of previous evidence for the contribution of learned safety to the CS-US delay gradient and suggest that some other process is also involved.  相似文献

Prediction models employing multiple linear regression of raw scores, multiple linear regression of factor scores, the single best predictor, and a nine-point decision rule index were compared. The subjects were 296 clients undergoing vocational counseling and evaluation. Predictor variables included performance ratings, demographic variables, and WAIS subtest scores; the criterion was employment status upon program completion. The least statistically sophisticated model, employing the single best predictor, was the most successful approach. Considerable shrinkage in power of prediction was demonstrated upon cross-validation particularly for multiple linear regression of raw scores model, indicating the necessity of cross-validating prediction schemes. Additional suggestions are made to those designing prediction studies.  相似文献

Active observer (participant) subjects were induced to make either a high or a low intimacy disclosure about themselves to a partner. Their (videotaped confederate) partner then disclosed either intimately or non-intimately in return. The impressions and attributions of these subjects were compared to the predictions of passive observer subjects (non-participants) who were each furnished with the original instructions, heard a tape recording of a different active observer's disclosure, and watched the same videotape of the confederate that person had seen. As expected, both active observers' responses and passive observers' predictions indicated a preference for the intimate partner. In addition, passive observers' attraction predictions were less positive than active observers' reports. But contrary to the hypotheses, passive observers predicted that active observers would attribute the partner's disclosure more to personalistic causes than was actually the case, and guessed inaccurately that active observers would interpret the partner's intimacy as an indicator of attraction. The methodological implications of these active-passive observer differences for research in self-disclosure and relationships are discussed.  相似文献

In an effort to extend our knowledge of career development, two indices of career maturity were investigated in a sample of 6029 high school seniors sampled from 57 Texas public school districts. The study investigated both the degree to which late adolescents choose occupations whose educational requirements match their stated educational goals and the degree to which students' vocational interests are compatible with their occupational choices. The correlations between educational plans and educational requirements of the chosen occupations were .41 or less. Of the subjects who claimed to have at least considerable understanding of their first choice career, only about half planned to achieve the amount of education appropriate to enter that occupation. Subjects' perceptions of how well they understood their occupational choices were also negligibly related to the compatibility of their vocational interests and their career choices. Although educational understanding and interest compatibility both contribute to realism of occupational choices, the correlation between these two indices of career maturity accounted for less than 1% of the variance.  相似文献

It is proposed here that individuals use their social interactions as opportunities to verify and confirm their self-conceptions. In a series of empirical investigations, three unique strategies of self-verification are examined. In Investigation I, participants were more likely to seek social feedback when they believed that it would confirm their self-conceptions. In Investigation II, participants elicited reactions from their interaction partners that confirmed their self-conceptions, especially when they suspected that their interaction partners' appraisals might disconfirm their self-conceptions. In Investigation III, participants preferentially recalled social feedback that confirmed their self-conceptions. Thus, within each of three distinct phases of the social interaction, people sought to verify their self-conceptions. The interplay of different strategies of self-verification and the conditions under which they will occur are discussed.  相似文献

A conceptual framework for the examination of alcohol and drug use as employee responses to work environments is proposed. Three sets of substance use antecedents are discussed. These are distancing forces, attractions, and constraints. Examples of these antecedents within the organizational setting are provided, and the dynamic interrelationships among them explored. Conditions for the use of different types of substances are also identified.  相似文献

Research in dream recall frequency has failed to isolate psychological variables which clearly and reliably differentiate frequent dream recallers from infrequent recallers. The present study tested the hypothesis that frequent recallers have a greater capacity for visual imagery than infrequent recallers. Subjects selected on the basis of reported dream recall frequency were administered a Paired-Associate Learning task designed to measure visual imagery, a rating scale of imagery clarity and vividness, and a subjective measure of imagery controllability. The results provide support for the hypothesis and, together with other evidence, suggest that a generalized capacity for visualization may contribute to the quality of the dreaming experience and, consequently, to its recallability.  相似文献

Subjects were angered by an instigator and then given a choice of two targets of aggression: one was a friend of the anger instigator and the other not. In addition, subjects were given a choice of more versus less intense aggression against these two targets. Angered subjects chose to give more intense aggression—regardless of whether the target was associated with the anger instigator. Thus, release of affect (opportunity to aggress intensely) predominated over association as a determinant of displacement.  相似文献

A theory of self-awareness was applied to aggression. In Experiment I, men were given an opportunity to aggress against women in the presence of a mirror, an audience, or neither. The mirror significantly inhibited aggression, but the audience did not. In Experiment II, an audience inhibited aggression, but only when there was frequent eye contact between the aggressor and the audience. These results were consistent with the predictions derived from the theory.  相似文献

Forty bilinguals from several language backgrounds were contrasted to a group of English-speaking monolinguals on a verbal-manual interference paradigm. For the monolinguals, concurrent finger-tapping rate during speech output tasks was disrupted only for the right hand, indicating left-hemisphere language dominance. Bilingual laterality patterns were a function of language used: native (L1) versus second acquired (L2), and age of L2 acquisition. Early bilinguals (L1 + L2 acquisition prior to age 6) revealed left-hemisphere dominance for both languages, whereas late bilinguals (L2 acquired beyond age 6) revealed left-hemisphere dominance only for L1 and symmetrical hemispheric involvement for L2.  相似文献

Paired-associate learning by children was investigated as a function of age (4 vs 7 yr), stimulus type (line drawing, color photograph, or object) and mode of elaboration (visual or verbal). Photographs and objects were associated with more learning than drawings at both ages and with both types of mediational elaboration. Only indirect evidence could be obtained for the prediction that differences among the three types of pictorial stimuli decrease with age. A previously reported Age × Elaboration interaction suggesting a relative disadvantage of visual elaboration for the younger children was not replicated.  相似文献
