Electrodermal activity during passive and active listening tasks of 43 healthy preschool children (aged 4 yr., 8 mo. to 6 yr., 5 mo.) was studied. The procedure included the following phases: baseline recording (3 min.), a passive listening task, instructions, and an active listening task. An increase in mean amplitude of skin conductance response (SCR) was found during the active listening task over the level for the passive listening task over 10 trials. On the passive listening task from Trial 1 to Trial 10, habituation of mean SCR amplitude occurred. The younger children, moreover, exhibited significantly greater habituation than the older children. Habituation of mean SCR amplitude did not occur during the active listening task. No significant difference was found in mean SCR amplitude during the active listening task for the two age groups. The children seemed to pay more attention during the active listening task than during the passive listening task. The younger children, moreover, are believed to have shorter attention spans. 相似文献

Abstract: Two studies were conducted to examine the relationship between ingroup identification, responsibility attribution, and attitude toward support provision. The data were collected from the participants of a simulated society game named SIMINSOC (Simulated International Society; Hirose, 1997 ). The global society in the game includes two rich regions and two poor regions, and the poor regions need to obtain support from rich regions for survival. In the two studies, participants were randomly assigned to either rich or poor regions, were engaged in various activities in the game, and answered questions concerning the identification, responsibility attribution, and attitude toward support provision. The results indicated that responsibility attributions were biased to favor the ingroups. Furthermore, poor regions believed that they should be supported more than the rich regions intended to provide support. Structural equation analyses suggested that the intergroup bias in attribution was increased when identification toward the ingroup was strong. The discussion considers the implications of the findings for interactions between groups. 相似文献

The authors developed a data-based profiling system in order to support offender profiling. The system stored incident records of prior offenders. Inputting offence details of an unsolved incident, a probability score was assigned to each prior offender in the system; the score represented the behavioral similarity with the unsolved incident. The system then ranked all offenders in the system according to the probability scores, and prioritized the high-ranked offenders as possible suspects. Moreover, the system inferred the characteristics of unknown offenders by accumulating characteristics of the high-ranked offenders. The system achieved promising accuracy, especially for linking crimes to perpetrators. In 45 out of 81 simulation trials, the target offenders were retrieved as a rank score of 1 from among 868 sex offenders. 相似文献

What are the benefits of negative thinking and negative affect? Although previous studies in evolutionary psychology, social psychology, and clinical psychology have clarified the question, there has been no definitive study asking people directly about the perceived benefits. In the present study, 119 Japanese undergraduates were asked how they recognized the benefits of negative thinking and negative affect. Their answers were analyzed qualitatively. The answers were arranged into 30 smaller categories and 12 superordinate ones. The benefits were divided into "benefits to the self" and "benefits to interpersonal relations". Finally, the conditions necessary for the negative thinking and negative affect being benign, and possible cultural differences, were discussed. 相似文献

Permanent lesions in the medial prefrontal cortex (mPFC) affect acquisition of conditioned responses (CRs) during trace eyeblink conditioning and retention of remotely acquired CRs. To clarify further roles of the mPFC in this type of learning, we investigated the participation of the mPFC in mnemonic processes both during and after daily conditioning using local microinfusion of the GABA(A) receptor agonist muscimol or the NMDA receptor antagonist APV into the rat mPFC. Muscimol infusions into the mPFC before daily conditioning significantly retarded CR acquisition and reduced CR expression if applied after sufficient learning. APV infusion also impaired acquisition of CRs, but not expression of well-learned CRs. When infusions were made immediately after daily conditioning, acquisition of the CR was partially impaired in both the muscimol and APV infusion groups. In contrast, rats that received muscimol infusions 3 h after daily conditioning exhibited improvement in their CR performance comparable to that of the control group. Both the pre- and post-conditioning infusion of muscimol had no effect on acquisition in the delay paradigm. These results suggest that the mPFC participates in both acquisition of a CR and the early stage of consolidation of memory in trace, but not delay eyeblink conditioning by NMDA receptor-mediated operations. 相似文献

To examine associations of suicidal ideation with somatic symptoms, 863 outpatients were studied in a psychosomatic clinic in Japan. All subjects were diagnosed according to the third and fourth editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R and DSM-IV). They completed the Cornell Medical Index Questionnaire to assess suicidal ideation and 15 major somatic symptoms. Mood states were rated using the Profile of Mood States (POMS). In the study, 266 patients (31%) reported suicidal ideation. The age- and sex-adjusted odds ratios (typically in the range of 1.5 to 2.5) of somatic symptoms for suicide ideation showed significant differences (all ps < .05) for 13 of 15 symptoms. The total number of somatic symptoms predicted suicidal ideation (p < .05), controlling for the significant effects of sex, education, marital status, and the POMS Depression scale scores through multiple regression analysis. Evaluation of somatic symptoms might be important to assess suicidal ideation in a psychosomatic medicine population. 相似文献

We investigated how motion lines drawn in the background of a running human silhouette affect motion impressions of a runner in a static image. Observers evaluated the strength and direction of motion impression. The results show that parallel lines do not enhance frontoparallel motion impressions, while converging lines do so in an in-depth direction. This is a counter-example to the hypothesis that motion lines in the background represent motion streaks of the background when one visually tracks a moving object. 相似文献

Two studies examined the effect of interpersonal attitude on reactions toward others' expression of anger or depression, Participants read a story in which their schoolmate experienced a negative event and expressed anger or depression, and reported their perceptions, affective reactions, and behavioural intentions such as support or rejection. The results indicated that an expression of anger elicited more negative reactions than an expression of depression only when a person whom participants disliked expressed the emotion. Furthermore, structural equation modelling indicated that the effect of interpersonal attitude on sympathy, blame, and support intention was mediated by the perception of the distressfulness of the event. The discussion considered the processes through which the expression of negative emotions evokes positive or negative interpersonal reactions. 相似文献

Background. Student learning theory (SLT) has established associations between students’ approaches to learning and their perceptions of the learning environment. SLT may provide a useful framework for researching student learning within the Japanese tertiary sector. Aims. The study aims to explore and validate the Course Experience Questionnaire (CEQ) and the Revised Study Process Questionnaire (R-SPQ-2F) in the Japanese four-year tertiary context. Sample. Mixed-major students from one Japanese four-year tertiary institution voluntarily completed the CEQ (n= 370). A separate group of students completed the CEQ and R-SPQ-2F (n= 269). Methods. CEQ data from the first sample were analysed using exploratory factor analysis (EFA). CEQ and R-SPQ-2F data from the second sample were analysed using confirmatory factor analysis (CFA). Results. EFA of the CEQ resulted in four factors: Good Teaching (GT), Generic Skills (GS), Appropriate Workload (AW), and Appropriate Assessment (AA). CFA confirmed these factors with the second sample. CFA of the R-SPQ-2F resulted in an item parcel-based, two-factor model. Correlations between some CEQ and R-SPQ-2F constructs were consistent with previous results. However, other findings from this research suggest that SLT constructs may be constituted differently in the Japanese context. Conclusions. This study represents an initial investigation of key SLT constructs in the Japanese context. Results suggest some SLT constructs are meaningful in this context, but further scale development may be desirable before more advanced modeling is employed. 相似文献
