We compared the predictions from several kinds of metamemory judgments (on the same set of items), both in terms of their predictive accuracy and in terms of the commonality of predictions. Undergraduates made judgments about the ease with which they could learn each item in a list (ease-of-learning judgments); then they learned every item, either to a minimal criterion of learning or with overlearning, and made judgments about how well they knew each item (judgments of knowing); finally, they returned 4 weeks later for a retention session and made feeling-of-knowing judgments on every time they could not recall, after which a recognition test assessed predictive accuracy. Ease-of-learning judgments had the least predictive accuracy. Surprisingly, however, the recognition of nonrecalled items was predicted equally well by judgments of knowing (made 4 weeks earlier) as by feeling-of-knowing judgments (made immediately prior to recognition). Moreover, those two kinds of judgments were only weakly correlated with each other, which implies that they do not tap memory in the same way.  相似文献

Do people feel that they are obliged to look after older parents and grandparents, support them financially, respect, obey, and maintain contact with them, as well as please them and make them happy? Two surveys of filial obligations were conducted in New Zealand involving 100 Chinese and 103 European families respectively. Across the 587 individuals from two generations, a widely shared obligation hierarchy emerged with social contact and respect on top of all others. Chinese were higher than Europeans on obedience and financial support as predicted, but also on most other obligations. Gender differences, contrary to prediction, were generally absent; but children were significantly higher than their parents on obedience. Obligations were moderately intercorrelated, and also correlated with corresponding expectations. K‐means cluster analysis was used in a novel way to discover three European and four Chinese family obligation types. Further family‐level analysis showed that parental income, grandparents’ residence, and motivations in communicating with elders differentiated the family types.  相似文献

Source memory has consistently been associated with prefrontal function in both normal and clinical populations. Nevertheless, the exact contribution of this brain region to source memory remains uncertain, and evidence suggests that processes used by young and older adults may differ. The authors explored the extent to which scores on composite measures of neuropsychological tests of frontal and medial temporal function differentially predicted the performance of young and older adults on source memory tasks. Results indicated that a frontal composite measure, consistently associated with source memory performance in older adults, was unrelated to source memory in young adults, although it was sensitive to a demanding working memory task. The memory composite score, however, predicted performance in the young group. In addition, item and source memory were correlated in young but not older people. Findings are discussed in terms of age-related differences in working memory and executive functions, and differential binding processes necessary for item and source memory. The requirement to integrate item and source information at encoding appears to place greater demands on executive or working memory processes in older adults than in younger adults.  相似文献

The genetic and environmental correlations between measures of normal (NEO-FFI) and abnormal personality (Dimensional Assessment of Personality Pathology: DAPP-BQ) were estimated in a sample of 545 volunteer general population twin pairs (269 monozygotic and 276 dizygotic pairs). The largest genetic correlations were observed between the 18 DAPP-BQ dimensions and NEO-FFI neuroticism (range = .05 to .81; median = .48), extraversion (range = -.65 to .33; median = -.28), agreeableness (range = -.65 to .00; median = -.38), and conscientiousness (range = -.76 to .52; median = -.31). The smallest genetic correlations were found between the DAPP-BQ dimensions and NEO-FFI openness (range = -.17 to .20; median = -.04). The environmental correlations are lower in magnitude but show the same pattern of correlations between DAPP-BQ and NEO-FFI scales. These results indicate that these two scales share a common broad-based genetic architecture, whereas the environmental influences show greater scale specificity.  相似文献

This selective review considers findings in genetic research that have shed light on how genes operate across development. We will address the question of whether the child is ‘father of the Man’ from a genetic perspective. In other words, do the same genetic influences affect the same traits across development? Using a ‘taster menu’ approach and prioritizing newer findings on cognitive and behavioral traits, examples from the following genetic disciplines will be discussed: (a) developmental quantitative genetics (such as longitudinal twin studies), (b) neurodevelopmental genetic syndromes with known genetic causes (such as Williams syndrome), (c) developmental candidate gene studies (such as those that link infant and adult populations), (d) developmental genome‐wide association studies (GWAS), and (e) DNA resequencing. Evidence presented here suggests that there is considerable genetic stability of cognitive and behavioral traits across development, but there is also evidence for genetic change. Quantitative genetic studies have a long history of assessing genetic continuity and change across development. It is now time for the newer, more technology‐enabled fields such as GWAS and DNA resequencing also to take on board the dynamic nature of human behavior.  相似文献

This study examined whether children 4- and 5-years-old (N = 156) can revise a physical science misconception from different types of picture books. A realistic fiction book and informational book with identical images matched in word count and reading difficulty level were compared to a control book about plants. In the pretest and posttest, children were asked to make predictions about pairs of objects that either had the same or different weight. The pretest scores showed that many children began with the misconception that heavier objects fall faster than lighter objects. Posttest scores revealed that children revised this misconception after reading the realistic fiction and informational picture books but not after reading the control book. These findings provide evidence that children as young as age 4 can acquire physical science knowledge from picture books and that both realistic fiction and informational books can be used effectively to expose children to science concepts.  相似文献

Taylor (1980) claims to show that the similarity in IQ between monozygotic twins reared apart (MZA's) in the three classic studies by Newman, Freeman, and Holzinger (1937), Shields (1962), and Juel-Nielsen (1965) is due to similarity in their environments. A reanalysis, using Taylor's classification of the twins into similar and dissimilar environments on the basis of four different criteria, but using the alternate IQ measure used in two of the studies, shows that his findings do not constructively replicate. Taylor's conclusion that “it seems reasonable to suggest that the IQ correlations characterizing pairs of individuals with absolutely identical genes and absolutely uncorrelated environments would be extremely low” cannot be substantiated from the evidence at hand.  相似文献

ABSTRACT

Use of verbal rehearsal is a key issue in memory development. However, we still lack detailed and triangulated information about the early development and the circumstances in which different forms of rehearsal are used. To further understand significant factors that affect children’s use of various forms of rehearsal, the present study involving 108 primary school children adopted a multi-method approach. It combined a carefully chosen word length effect method with a self-paced presentation time method to obtain behavioural indicators of verbal rehearsal. In addition, subsequent trial-by-trial self-reports were gathered. Word length effects in recall suggested that phonological recoding (converting images to names – a necessary precursor for rehearsal) took place, with evidence of more rehearsal among children with higher performance levels. According to self-paced presentation times, cumulative rehearsal was the dominant form of rehearsal only for children with higher spans on difficult trials. The combined results of self-paced times and word length effects in recall suggest that “naming” as simple form of rehearsal was dominant for most children. Self-reports were in line with these conclusions. Additionally, children used a mixture of strategies with considerable intra-individual variability, yet strategy use was nevertheless linked to age as well as performance levels.  相似文献

This paper reviews two studies on between-classroom variation in bullying by Mahdavi and Smith and by Atria, Strohmeier, and Spiel in this issue. Both studies demonstrated large variability between classrooms in the prevalence of bullying and the distribution of participant roles. The authors of the original studies consider this variability at odds with the influential participant roles and scapegoating approaches to bullying. In contrast, this review proposes that the essence of these theoretical approaches is to explain variance, both within and between classrooms, and over time. More explicit theorizing concerning determinants of between-classroom variance and assessment of classroom-level variables implicated by this theorizing are called for.  相似文献

Abstract: Two statistical meta-analyses synthesized 33 empirical studies which investigated the correlation between relationship satisfaction and two types of love: Erotic Love and Companionate Love, measured by various love scales based on four major theories by Rubin, Lee, Hatfield, and Sternberg. The results drawn by the Hunter-Schmidt method showed that satisfaction was highly correlated with Erotic Love, but that its correlation with Companionate Love was unclear due to heterogeneity in the total sample of the all Companionate Love studies. A moderator analysis indicated a potential moderator, that is, theoretical differences between Lee's Color Theory of Love and the other three theories. The result suggested that a Companionate Love named "Storge" in the Color Theory should not be mixed up with other friendship-style loves defined by other theories as the Storge subscale would measure a different psychological construct.  相似文献

The role of relatives' expressed emotion (EE) in mediating the efficacy of family interventions has been studied in randomized controlled trials (RCTs) involving people with schizophrenia and depression. Reanalysis of two RCTs (n=48) by Leff (1989) indicated that lowering relatives' EE and/or reducing social contact between the patient and family members accounted for the efficacy of the intervention for schizophrenia. However, this relationship has not been investigated previously with regard to depression, and this paper presents the results of a recent RCT which included measurement of EE and other possible mediating variables. In this study, amelioration of the critical attitude of the partner did not account for the superiority of couples therapy over antidepressant medication, since the same change occurred in the drug group. However, reducing the patient's exposure to the partner's hostility partially explained the efficacy of couples therapy. Further research on the process of change in families undergoing therapy is indicated to identify the variables that account for the efficacy of therapy.  相似文献

This study investigated whether the relation between implicit and explicit homonegativity measures is affected by self-presentation concerns, since previous research in this area has been inconclusive. In Experiment 1, 70 high-school students made evaluative ratings of pictures of homosexual and heterosexual couples. Self-presentation was manipulated by either instructing participants that the study concerned attitudes regarding sexual orientation (socially sensitive) or attitudes regarding age (less sensitive). The age-instruction led to increased homonegativity but not to a stronger correlation with an Implicit Association Test (IAT; Greenwald, McGhee & Schwartz, 1998) with homo/heterosexual couples. Concerns regarding the construct validity of the present implementation of the IAT were alleviated in Experiment 2, where heterosexual (n= 30) but not homosexual (n= 30) participants showed implicit homonegativity. The current findings are problematic for the interpretation of low correspondence between implicit and explicit attitude measures as being primarily an effect of self-presentation concerns.  相似文献

Expertise can be acquired through experience or through education, and many occupations demand a mixture of both. In this paper we evaluate the level of expertise acquired through these two routes by comparing credit decisions made by professional credit managers (who have learned through experience rather than education) and lecturers and students in management, (who have no experience but have learned the relevant concepts). We also tested a control group of laypeople with neither relevant formal education nor experience. Participants assumed the role of credit manager and made creditworthiness predictions and credit granting decisions for six companies with known performance. Lecturers and students generally outperformed credit managers on the prediction tasks, and the credit managers performed only slightly better than laypeople. In short, for at least one domain, it appears to be more efficient to learn from formal education than from experience. We argue that the prerequisites for successful learning are largely absent from the everyday experience of credit managers, but are present in an educational context.  相似文献

We investigated whether (a) depression prevention was associated with depressive symptoms and medial-frontal alpha asymmetry in adolescents; (b) alpha asymmetry mediated the association between participation in a prevention program and depressive symptoms; and (c) gender affects these associations. In our randomised control group study, we compared a universal prevention program (n = 40 adolescents, 14 females) with a non-intervention control condition (n = 39 adolescents, 20 females) in German secondary school students (mean age: 13.53 years, SD = 0.53). We collected data at baseline, post-intervention, 6-month, and 12-month follow-up using the Self-Rating Questionnaire for Depressive Disorders (SBB-DES) and resting medial-frontal alpha activity on F3 and F4. We found that girls benefitted from participating in the prevention program in regards to their depressive symptoms at 12-month follow-up but not alpha asymmetry. In boys, participation in the prevention program was associated with their alpha asymmetry at 6-month follow-up but not their depressive symptoms. Alpha asymmetry did not mediate the effects of the prevention program on depressive symptoms in either gender. Although participation in the prevention program was associated with both depressive symptoms and alpha asymmetry, those associations seem independent from each other. Possible explanations for this result pattern are discussed.  相似文献

There is some debate surrounding the cognitive resources underlying backward digit recall. Some researchers consider it to differ from forward digit recall due to the involvement of executive control, while others suggest that backward recall involves visuospatial resources. Five experiments therefore investigated the role of executive-attentional and visuospatial resources in both forward and backward digit recall. In the first, participants completed visuospatial 0-back and 2-back tasks during the encoding of information to be remembered. The concurrent tasks did not differentially disrupt performance on backward digit recall, relative to forward digit recall. Experiment 2 shifted concurrent load to the recall phase instead and, in this case, revealed a larger effect of both tasks on backward recall, relative to forwards recall, suggesting that backward recall may draw on additional resources during the recall phase and that these resources are visuospatial in nature. Experiments 3 and 4 then further investigated the role of visual processes in forward and backward recall using dynamic visual noise (DVN). In Experiment 3, DVN was presented during encoding of information to be remembered and had no effect upon performance. However, in Experiment 4, it was presented during the recall phase, and the results provided evidence of a role for visual imagery in backward digit recall. These results were replicated in Experiment 5, in which the same list length was used for forward and backward recall tasks. The findings are discussed in terms of both theoretical and practical implications.  相似文献

The purpose of this study was to explore whether (a) immigrant health care workers (HCW) are more at risk of bullying at work than Danish staff members, (b) this association is increased by previous exposure to bullying and (c) immigrants experience more bullying from supervisors, colleagues and clients/residents. We analyzed cross-sectional baseline data from 5,635 health care students of whom 10.4% were immigrants, and conducted a prospective analysis by following 3,109 of these respondents during their first year of employment. More than a third of the respondents had previous experiences with bullying. The baseline analyses showed that immigrants are more at risk of being bullied during both their theoretical education and trainee periods than their Danish co-students. At follow-up we found that 9.1% of the total cohort had been exposed to bullying at work during their first year of employment, hereof 1.8% frequently. "Non-Western" immigrants had a significantly higher risk of exposure to bullying at work during follow-up than the Danish respondents independent of previous experience with bullying. Danish and immigrant health care workers were more exposed to bullying from co-workers than from supervisors with no statistically significant difference between the Danes and the immigrant groups. Both "Western" and "non-Western" respondents were more at risk of bullying from clients/residents than the Danish respondents.  相似文献

We propose a theoretical framework that explores the accumulation of work interruptions and their effects. Most research studies have dealt with interruptions as isolated phenomena, ignoring the simultaneous or sequential occurrence of interruptions common in everyday life. We fill this gap and provide insight into the process of the accumulation of interruptions by mapping deep-level regulation onto an observable sequence of actions. Furthermore, we explain how cumulative interruptions can lead to qualitatively different effects because of the interaction and joint development of isolated effects, identifying some mediating and moderating factors. In doing so, we disclose the relationships between the effects of single interruptions found in laboratory studies and the impacts on health and well-being of multiple interruptions found in applied research.  相似文献

There is mounting evidence that physical aggression and nonaggressive, rule‐breaking delinquency constitute two separable though correlated subtypes of antisocial behavior. Even so, it remains unclear whether these behavioral subtypes have meaningfully different interpersonal correlates, particularly as they are subsumed within the same broad domain of antisocial behavior. To evaluate this, we examined whether hostile perceptions of others (assessed via exposure to a series of neutral unknown faces) were linked to level and type of antisocial behavior aggression vs. rule‐breaking, and moreover, whether this association persisted even when also considering the common association with negative affect (as manipulated via written recollection of one's best and worst life experiences). Analyses revealed that aggression, but not rule‐breaking, was uniquely tied to hostile perceptions of others. Furthermore, this association persisted over and above the common association of both hostile perceptions and aggression with negative affect (at both trait and state levels). Such results provide additional support for clinically meaningful differences between the behavioral subtypes of aggression and nonaggressive rule‐breaking and for the independent role of hostile perceptions in aggressive behavior.

To what extent does semantic information play a functional role in visual word recognition? Theories of word recognition vary in the importance assigned to semantic information in visual lexical decision, with past research suggesting that the nature of the foils is a crucial determinant of semantic reliance. Here, we explored the conditions under which semantic variables influence lexical decision. Normal readers performed visual lexical decision tasks in which imageability and semantic priming were manipulated, with nonword foils varying systematically in their orthographic and phonological similarity to the real words. The effects of imageability and semantic priming increased in magnitude as nonword foils became progressively more wordlike. These findings provide a clear illustration of the flexible use of semantic information to support normal visual word recognition.  相似文献
