This study investigated whether prompting children to generate predictions about an outcome facilitates activation of prior knowledge and improves belief revision. 51 children aged 9–12 were tested on two experimental tasks in which generating a prediction was compared to closely matched control conditions, as well as on a test of executive functions (EF). In Experiment 1, we showed that children exhibited a pupillary surprise response to events that they had predicted incorrectly, hypothesized to reflect the transient release of noradrenaline in response to cognitive conflict. However, children's surprise response was not associated with better belief revision, in contrast to a previous study involving adults. Experiment 2 revealed that, while generating predictions helped children activate their prior knowledge, only those with better inhibitory control skills learned from incorrectly predicted outcomes. Together, these results suggest that good inhibitory control skills are needed for learning through cognitive conflict. Thus, generating predictions benefits learning – but only among children with sufficient EF capacities to harness surprise for revising their beliefs. 相似文献

This article reviews the causal implications of latent variable and psychometric network models for the validation of personality trait questionnaires. These models imply different data generating mechanisms that have important consequences for the validity and validation of questionnaires. From this review, we formalize a framework for assessing the evidence for the validity of questionnaires from the psychometric network perspective. We focus specifically on the structural phase of validation, where items are assessed for redundancy, dimensionality, and internal structure. In this discussion, we underline the importance of identifying unique personality components (i.e. an item or set of items that share a unique common cause) and representing the breadth of each trait's domain in personality networks. After, we argue that psychometric network models have measures that are statistically equivalent to factor models but we suggest that their substantive interpretations differ. Finally, we provide a novel measure of structural consistency, which provides complementary information to internal consistency measures. We close with future directions for how external validation can be executed using psychometric network models. © 2020 European Association of Personality Psychology 相似文献

We investigated whether the memorability-based strategy, a process supporting the rejection of nonexperienced event occurrence, could be promoted through training. The performance of children who received memorability-based training was compared with that of (a) children who received source-monitoring training and (b) children who did not receive any specific training but were instructed to be as accurate as possible. Participants (142 6- to 10-year-olds) enacted common and bizarre actions. Eighteen days later, participants received misinformation about the first session. Five days after being misinformed, children were questioned about the first session. Compared with children in the no training condition, those in both training conditions reported significantly more true events, but only older children who received the memorability-based training were more likely to reject bizarre suggested events. Age interacted with action type when metacognitive assessments about false event rejection were examined, consistent with the idea that the use of the memorability-based strategy develops late during the elementary school years. 相似文献

In this study were examined differences in attentional style of athletes engaged in two open skill sports requiring high reactivity (karate and volleyball) in groups with high or low experience. 42 healthy men, 24 volleyball players, 12 of High Experience (first division Italian League players whose M age was 28 yr. (SD=5) and 12 of Low Experience (prejunior Italian team athletes whose M age was 19 yr. (SD= 2). and 18 karateka, 9 of High Experience (3rd and 4th dan black belt athletes whose M age was 31 yr., SD=5) and 9 of Low Experience (1st and 2nd dan black belt karateka whose M age was 32 yr., SD=5). Tests involved different types of attention: Alert, Go/No-Go, Divided Attention, and Working Memory. For each one, the reaction time (RT), variability, change in RT, and number of errors were analysed. Karateka of High Experience reacted faster than those of Low Experience on the simple RT test, Alert (M RT: 204 vs 237 msec., p< .01), while on the Divided Attention test, the High Experience subjects performed more poorly and committed more errors (M errors: 4.89 vs 1.44, p <.003). Young volleyball players of Low Experience reacted faster than colleagues of High Experience on the Alert (M RT: 187 vs 210 msec., p<.01) and Divided Attention tests (M RT: 590 vs 688 msec., p<.001) but committed more errors (Divided Attention test, M errors: 6.50 vs 3.08, p<.007). For the Divided Attention and Working Memory tests, correlations were positive among errors, RT, and RT variability but only for volleyball athletes of High Experience, suggesting they showed higher attention and stability in complex reactions than the group with Low Experience. No significant correlations were noted for either group of karateka on complex reactions. Results suggested that the attentional resources were engaged in different ways in the two groups of athletes and, in each group, there were differences between persons of High and Low Experience. 相似文献

Considering the many theoretical and methodological viewpoints in the field of evaluation, a guideline was established to facilitate the evaluation of social intervention programs. For this purpose, the goals of the evaluation were taken into account: (a) planning interventions, (b) learning and continuous improvement of interventions, (c) programming policies, and (d) transformation of society. These goals will determine the perspective of the analysis selected (focusing on the evaluand or the context) and the strategies for change employed (focusing on processes or results). The elements that, according to Shadish, Cook, and Levinton (1991), constitute the theory of evaluation (evaluand, value, building of knowledge, and uses) have also been considered. The analysis of all these components led to the elaboration of a guideline to orient the practice of evaluation from a pragmatic perspective, in accordance with the demands and needs of a certain social context. 相似文献

The aim of this study was to evaluate the efficacy of cognitive therapy (CT) in the treatment of generalized anxiety disorder
(GAD), as it would be reflected through both psychological and psychoneuroendocrinological parameters. For this purpose, a
group of outpatients with GAD were treated with CT for up to a maximum of 24 sessions. In order to assess psychological and
biological changes, anxiety-related symptoms were evaluated according to the Hamilton Anxiety Rating Scale (HAM-A), and the
hypothalamic-pituitary-adrenal (HPA) function was determined through assessment of circulating cortisol levels. A significant
decrease in the HAM-A scores, along with significant changes in plasma cortisol levels, were observed after completion of
treatment with CT. These observations contribute to demonstrate that the effect of certain psychotherapeutic approaches, such
as CT, may be observed at both psychological and biological levels. 相似文献

The human capacity for self‐awareness allows people to envision their eventual death and thus creates the potential for debilitating anxiety. Terror management research has shown that self‐awareness exacerbates the experience of mortality salience. I suggest that self‐awareness alone can induce mortality salience through dialectical thinking. If constructs include a concept and its opposite, then focusing on one aspect should also increase awareness of the opposite. Focusing on the existing object self should thus lead to the recognition of the non‐existent self that is implied. In study 1, participants experienced one of two self‐awareness manipulations (exposure to a mirror, perceiving the self as distinctive) or no manipulation; mortality salience was measured using a death‐relevant word completion task. Both self‐awareness conditions reported significantly higher mortality salience than the control condition. In study 2, participants exposed to their reflection reported increased death salience and life salience (as measured by death‐ and life‐relevant word completion tasks) than a control group, which directly suggests that self‐awareness leads people to dialectically consider opposing facets of the self. Terror management and objective self‐awareness theories might thus be more intimately tied than was previously thought. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

In 1980, Bloom and Fischler published a paper describing a set of sentence contexts (SCs) and their cloze probabilities (CPs).
This material has subsequently been employed in numerous studies of linguistic processing. We sought to define the completion
words and their CPs for Bloom and Fischler’s sentences in an inner-city British population in order to establish reliable
norms for subsequent studies in the U.K. One hundred and fifty incomplete SCs were presented to 73 volunteers. The CPs for
each of the words used to complete the SCs were computed. We then compared the CPs from our sample with those from Bloom and
Fischler. There were significant differences between CPs from each sample in 14% of the SCs analyzed (p < .01). Our data suggest that studies employing SCs and CPs may require locally defined norms if the test population differs
substantially from the original one. The consequences of employing SCs and CPs to study linguistic processing without normalization
are discussed. 相似文献

The present study was a qualitative exploration into the meaning of ethnic identity and its association with college adjustment in students attending ethnically diverse university campuses. The sample consisted of 103 participants recruited from 2 ethnically diverse universities in southern California. A constant comparative analysis of the interview data revealed 9 themes as being relevant to students' experiences of ethnicity within a multiethnic campus that reflect both the positive aspects and the negative aspects associated with campus diversity. Students' experiences with campus diversity varied by ethnic background and type of institution attended, as did the overall frequencies of reported positive and negative themes associated with diversity. The implications of these findings for ethnic identity, campus climate, and interethnic relations are discussed. 相似文献
