The usual superiority in frequency-of-occurrence judgments of younger vs. older subjects was hypothesized to result from greater strategic encoding of the materials conveying frequency information. A subject-paced, visual search task was designed to control nontarget word encoding. Relative frequency judgments for the nontarget word pairs were equally accurate for younger and older subjects, and performance of both groups was above chance. Results suggest that strategic cover-task encoding can induce age differences in incidental frequency processing. Consistent with a nonoptimal as opposed to an optimal view, automatic processes require only minimal capacity for above-chance performance, but additional strategic resources can increase performance. When such additional resources are used more by younger than by older subjects, the former are better in frequency performance. 相似文献

The Cook and Medley (1954) Hostility (Ho) scale has been used in several important studies evaluating potential health consequences of hostility. A relative lack of compelling information about the construct validity of the Ho scale, however, has raised concerns about the appropriate interpretation of previous research. In this study, 60 married couples discussed a low conflict topic, a high conflict topic, and then a second low conflict topic. High Ho men responded to the high conflict topic with significant increases in self-reported anger and anxiety and overt hostile behavior, but low Ho men did not. Furthermore, compared to low Ho men, high Ho men blamed their wives more for their usual disagreements on the high conflict topic and saw their disagreement-engendering behavior as more intentional. Among women, Ho scores were weakly related only to overt hostile behavior. Finally, couples consisting of two low Ho persons displayed a uniquely agreeable interactional style. 相似文献

The word-length effect is the advantage that lists of short words show over lists of long words in immediate recall. Typically, the word-length effect is used as strong support for decay-based theories of immediate retention. However, the present two experiments show that the traditional word-length effect emerges only after several trials in an experimental session, a result reminiscent of earlier findings in distractor-based short-term forgetting experiments. These results suggest that any complete account of the word-length effect will need to consider a role for proactive interference. 相似文献

There has been a paucity of research that has investigated whether skilled performers of a complex sports skill can readily change their technique. This study was designed to investigate whether swimmers skilled in the conventional breaststroke technique could adjust readily to the wave action technique. Nine masters swimmers with well established and stable movement patterns for the conventional technique were coached in the wave action breaststroke technique. The swimmers were videotaped from the side during maximum speed trials of the conventional breaststroke technique before coaching and the wave action technique after ten 45-minute coaching sessions. The amplitude and phase of the waveforms comprising the vertical displacements of the body parts were determined by Fourier analysis. In response to the coaching, the amplitude of the fundamental frequency of the vertex of the head, shoulders, hips, and knees increased significantly (p < 0.01). The percentage of power contained in the fundamental frequency of the shoulder and hip vertical displacements also increased significantly (p < 0.01). All subjects changed the relative phase of the fundamental frequencies of the vertex, shoulder, and hip vertical displacements. It was concluded that in this complex skill, major changes to the low frequency waveforms comprising the motion were achieved readily. 相似文献

Forty boys and their parents completed measures of dissociation, state anxiety, and perceptions of parental behaviors. Mothers completed a behavior problems checklist about their sons. The results indicated a correspondence between fathers' and sons' dissociation scores. In addition, links were found between parental dissociation, parental inconsistency and rejection, and child dissociation. The findings are discussed in the context of several recently proposed models of the etiology of child dissociative disorders. 相似文献

The question of whether or not lexical information is accessed directly from a visual code or by a process of phonetic mediation was investigated in three lexical decision experiments. Phonetic similarity influenced decisions about visually presented words only when they were to be discriminated from orthographically regular nonwords. When consonant strings or random letter strings were used as nonwords, phonetic similarity effects were absent, and graphemic similarity exerted a powerful effect while evidence of semantic priming was found. This pattern was interpreted as evidence of direct lexical access, which is probably the normal processing mode for skilled readers. Phonetic coding, when it occurs, may be a storage strategy rather than a part of the addressing chain for lexical structures. 相似文献

The relationship between feminism and sex roles was explored in two studies. In female college students, sex-role types were measured by Baucom's (1976) MSC and FMN scales and by Bem's Sex-Role Inventory (Bem, 1974). Feminism was measured by the Attitude Toward Women Scale (AWS, Short Form) (Spence & Helmreich, 1972) and the Women's Liberation Scale (WLS) (Goldberg, 1976). Two groups of women were predicted to be more profeminist than others. (a) those scoring high on both masculinity and femininity and (b) those scoring high on masculinity and low on femininity. Results of the study supported both hypotheses using the AWS but not the WLS. In the second study, MSC and FMN served as the basis for forming sex-role types, and feminism was measured by participation in NOW. Again, a large number of women high on masculinity and low on femininity were feminists: however, women high on both masculinity and femininity were underrepresented in NOW. Different results in the two studies are discussed in terms of the different ways that feminism was measured. 相似文献

This study examined the generalization and maintenance effects of three phases of parent training (Instructions plus Feedback and two Self-management Training phases) on levels of disruptive child behavior and the accuracy with which parents implemented programs. Data were collected from five families in three main settings: the initial training setting (the home), a variety of generalization settings in the community, and the family breakfast. A multiple baseline across subjects design was used. Instructions plus Feedback comprised instructing parents to use a range of behavior management procedures and provided home-based differential feedback concerning accuracy of program implementation. Self-management Training phases involved training parents in goal setting, self-monitoring, and planning skills, specific to their performance of appropriate parenting skills in generalization settings. Results indicated that the Instructions plus Feedback phase was sufficient to produce reduced levels of problem behavior at home and high levels of accurate implementation, but generalization effects out of home were equivocal. Self-management maintained reduced levels of problem behavior at home but, in addition, resulted in generalization effects in community settings for both children and parents. Maintenance probes 3 months following the program revealed the effects had been maintained. 相似文献

Towards a model of stress and human performance 总被引:19,自引:0,他引:19
A F Sanders 《Acta psychologica》1983,53(1):61-97
An outline is presented of a model that aims to relate energetical and structural mechanisms of human information processing and to incorporate an interactionally defined stress notion in performance research. The first section summarizes objections to unidimensional notions of arousal and stress. It is concluded that further progress requires the analysis of joint cognitive-energetical processing structures. In the second section two current performance models - in terms of linear stages and resources - are briefly reviewed. Despite a number of problems and objections, it is decided to base the model upon linear stage notions of information processing. This is further elaborated in the third section. In accord with Pribram and McGuinness (1975) three energetical supply systems are proposed which are selectively related to specific cognitive processing mechanisms. Stress is defined as a state of imbalance in the energetical supply which is difficult to restore or to compensate. The final section is devoted to the discussion of some lines of evidence and to suggestions for future research. 相似文献

In three experiments, adult humans were tested in a feature-positive or feature-negative simultaneous symbol task. In Experiment 1, some persons focused on the correct side of the stimulus cards, whereas other persons focused on the not-correct side of the stimulus cards. The feature-positive group learned faster than the feature-negative group did in the correct side condition; the feature-negative group learned faster than the feature-positive group did in the not-correct side condition. In Experiments 2 and 3, all persons focused on both the correct and not-correct sides of the stimulus cards. Under these circumstances, feature-positive and feature-negative performances were comparable. These results indicated that the usual superiority of feature-positive over feature-negative learning results from a tendency to attend to only a portion of the stimulus array. 相似文献
