The present research investigated in a dual task design the effects of extraversion level and structural task properties on the recall of an incidentally learned text. First, the hypothetical relation between arousal level and attentional selectivity was tested. Second, the relation between structural levels in the text and recall of text elements was studied. It was found that (a) extraverts performed significantly better on incidental recall compared to introverts; (b) the nuclear sentences at the top of the hierarchical structure were the best recalled sentences, independently of arousal level; (c) the effect of differences in arousal on recall was only significant in case of the top sentences. The effect was absent in case of specificúsecondary sentences. 相似文献

The relationship of characteristics of the social environment to the adaptation of adolescents from high-risk predisposing environments was examined. Specifically, the degree to which adolescents' perceptions of various dimensions of their family and school environment as well as sources of social support related to differential levels of personal well-being and academic adjustment was explored. Multiple regression analyses revealed differences in the salience of the dimensions of the social environment as a function of the particular sphere of functioning under consideration. Implications of the findings for developing a model for understanding the relative vulnerability of individuals at risk as well as of the design of preventive interventions are discussed. 相似文献

Information is given about a series of studies with Allsopp and Feldman's ASB scale (1976) in its Spanish version, which compliments the information collected in Silva, Martorell and Clemente (1986a). It deals with test-retest reliability with an interval of 12 months; with comparisons between anonymous and non-anonymous data, and comparison between self-evaluation and evaluation by others. The results support the metric quality of the ASB scale, inviting revision of some of the common criticisms made of these types of instruments. 相似文献

This study explores consumers' behaviour regarding sustainable mobility options. A mixed-methods approach was adopted to examine the impact of bio-altruistic values, egoistic values, environmental attitudes, attitudes regarding sustainable mobility, perceived behavioural control and subjective norms on the likelihood of choosing sustainable mobility options. To collect the data, an online survey was applied to a sample of 645 Portuguese consumers, which included one single non-mandatory open-ended question to understand which factors could contribute to increase respondents' likelihood to choose more sustainable transport modes. As most studies in the mobility field are quantitative, combining both quantitative and qualitative data provided a greater in-depth analysis with richer findings. Firstly, findings revealed that attitudes towards sustainable mobility, subjective norms, perceived behaviour control, and egoistic values influence the likelihood of choosing sustainable mobility options. However, environmental attitudes, altruistic and biospheric values do not impact this choice. Secondly, consumers highlight that the existence of a broad public transport network, safe bicycle lanes, and accessible prices would contribute to their likelihood of adopting more sustainable mobility behaviours. The content analysis of 402 answers allowed to discover new dimensions that influence sustainable mobility behaviour, such as safety, respect towards bicycle users, mindset adjustment, willpower, and especially physical efforts associated with long distances, bad weather, orography, and the difficulty to transport materials or other people. Based on both quantitative and qualitative findings, the paper provides key recommendations for politicians, urban planners, and transport organisations, that according to respondents, would contribute to increase their use of sustainable mobility. 相似文献

The objective of the present study was to examine if the Outcome Bias also occurs in pilots flying under instrument flight rules (IFR). In a scenario-based survey, 60 pilots evaluated weather-related decisions made by hypothetical pilots. Participants rated the decisions as better, less risky, and regarded the probability that they would have made the same decision as higher when they were followed by a positive outcome, than when they were followed by a negative outcome. This effect showed likewise for novice pilots and for experienced pilots. These findings could be relevant for the flight-related decision-making of pilots, which sometimes is affected by the decisions made by third-party pilots. In particular, decisions made by other pilots that have led to positive outcomes might be hastily followed, whereas those that have led to negative outcomes might be hastily rejected. 相似文献

Benzodiazepine receptor ligand influences on acquisition: suggestion of an endogenous modulatory mechanism mediated by benzodiazepine receptors 总被引:2,自引:0,他引:2
In rats, pretraining ip administration of the central benzodiazepine receptor antagonist, flumazenil (5.0 mg/kg), or of the inverse agonist, n-butyl-beta-carboline-3-carboxylate (BCCB) (0.2 or 0.5 mg/kg), facilitated retention of a step-down inhibitory avoidance task; the central agonists, clonazepam and diazepam (0.4 or 1.0 mg/kg), had an opposite effect, and the peripheral agonist, 4'-chlordiazepam (1.25 or 6.25 mg/kg), was without effect. Pre- but not post-training flumazenil (2.0 mg/kg) blocked the effect of BCCB (0.5 mg/kg), clonazepam (1.0 mg/kg), or diazepam (1.0 mg/kg) given also pretraining. The post-training administration of all of these drugs had no effect on retention of the avoidance task. Flumazenil (5.0 mg/kg) and BCCB (0.5 mg/kg), given before training, enhanced retention test performance of habituation to a buzzer but not of habituation to an open field. In the three tasks studied, none of the drugs used had any appreciable effect on training session parameters. These results suggest that there is an endogenous mechanism mediated by benzodiazepine agonists, sensitive to inverse agonists, that normally down-regulates acquisition of certain behaviors; this mechanism becomes activated only when the tasks involve or occur with a certain degree of stress or anxiety (i.e., inhibitory avoidance or habituation to the buzzer) and not in less stressful or anxiogenic tasks (i.e., habituation to an open field). 相似文献

This study was designed to analyze whether Mental Rotation (MR) played a role as a mediating variable for sex-related differences in Visualization (VZ). Two psychometric tests measuring MR and VZ were applied to a representative sample of 309 males and 390 females in their last year of high school. Three non-zero correlations between sex and MR, sex and VZ, and MR and VZ were found, and the effect of sex on VZ was eliminated when MR was introduced as a covariable. When three subgroups of different VZ ability were made by dividing up the VZ distribution by the first and third quartiles, sex-differences were only found for the high-scorers group, for which previous results were replicated. Results clearly indicate that MR is a plausible mediator variable for sex differences in VZ when such differences do exist. Theoretical, methodological and practical consequences of these results are discussed. 相似文献

Tested a theoretical model on the effects of social role identity, illness intrusion, and competence on psychological well-being among 109 low-income Latinas with arthritis. All six roles studied were rated as highly important identities. Sex-role nontraditionalism was associated with less importance of the homemaker, mother, and grandmother roles. Negative affect increased as a function of intrusions into valued identities. Having important role identities contributed to feelings of competence (i.e., self-esteem and self-efficacy), which in turn, contributed to psychological well-being. Competence also mediated the effects of pain, identity, and illness intrusions on psychological well-being. Results suggest competence processes play an important role in well-being. 相似文献
