The aim of this study was to investigate the cross‐sectional and longitudinal relationships between general parenting and body mass index (BMI) status of children between the ages of 4 and 7 in Australia. A nationally representative sample of 4,423 children (49% female) and their parents was used for the present study. Measures of parental demandingness and responsiveness were completed by parents at child age 4–5 years. Height and weight measurements of children were taken at child age 4–5, and again at 6–7, from which BMI status was calculated. No influence of mothers' parenting on child BMI status was shown, and fathers' responsiveness was found to be predictive of increased risk for overweight/obesity at 6–7 years. While the present study is complicated by measurement issues, findings suggest that increased risk for overweight in young children may be associated with responsiveness in fathers. Obesity prevention programs involving parents should take into account the influence of fathers' parenting on child BMI status.  相似文献

Decades of research on visual perception has uncovered many phenomena, such as binocular rivalry, backward masking, and the attentional blink, that reflect ‘failures of consciousness’. Although stimuli do not reach awareness in these paradigms, there is evidence that they nevertheless undergo semantic processing. Object substitution masking (OSM), however, appears to be the exception to this rule. In OSM, a temporally-trailing four-dot mask interferes with target perception, even though it has different contours from and does not spatially overlap with the target. Previous research suggests that OSM has an early locus, blocking the extraction of semantic information. Here, we refute this claim, showing implicit semantic perception in OSM using a target-mask priming paradigm. We conclude that semantic information suppressed via OSM can nevertheless guide behavior.  相似文献

Visual short-term memory (VSTM) research suggests that the adult capacity is limited to three or four multifeature object representations. Despite evidence supporting a developmental increase in capacity, it remains unclear what the unit of capacity is in children. The current study employed the change detection paradigm to investigate both the capacity and nature of the representations of VSTM in 7-year-olds, 10-year-olds, and adults. Two experimental conditions were used to compare memory performance for single-feature objects with that for multifeature objects. Results provided further and more convincing evidence for a developmental increase in VSTM. Furthermore, the “loading up” of features in the multifeature condition was found to incur no significant performance deficit in all age groups. These findings are explained in terms of a developmental increase in the number of integrated multifeature object representations in VSTM.  相似文献

Researchers suggest that observers of innocent suffering will negatively evaluate the victim as a strategy for maintaining their belief in a just world. We propose an alternative class of strategies and test whether individual differences in repressive coping style predict the type of strategy people will use. In the first two studies, we exposed repressors versus nonrepressors to victims whose suffering should pose a high versus low threat to the need to believe in a just world. Repressors had a greater tendency to positively reappraise the high threat victim's suffering. Nonrepressors had a greater tendency to negatively evaluate the high threat victim. A third study replicated the results for the high threat conditions and suggested that repressors' positive reappraisal is not because of a tendency to minimize suffering. Our research (i) demonstrates a class of strategies for preserving the belief in a just world other than negatively evaluating the victim and (ii) is among the first to examine directly an individual difference predictor of alternative just‐world preservation strategies.

Conversation is multi-modal, involving both talk and gesture. Does understanding depictive gestures engage processes similar to those recruited in the comprehension of drawings or photographs? Event-related brain potentials (ERPs) were recorded from neurotypical adults as they viewed spontaneously produced depictive gestures preceded by congruent and incongruent contexts. Gestures were presented either dynamically in short, soundless video-clips, or statically as freeze frames extracted from gesture videos. In a separate ERP experiment, the same participants viewed related or unrelated pairs of photographs depicting common real-world objects. Both object photos and gesture stimuli elicited less negative ERPs from 400 to 600 ms post-stimulus when preceded by matching versus mismatching contexts (dN450). Object photos and static gesture stills also elicited less negative ERPs between 300 and 400 ms post-stimulus (dN300). Findings demonstrate commonalities between the conceptual integration processes underlying the interpretation of iconic gestures and other types of image-based representations of the visual world.  相似文献

Delayed alternation and object alternation are classic spatial and non-spatial delayed response tasks. We tested 632 middle-aged male veteran twins on variants of these tasks in order to compare test difficulty, measure their inter-correlation, test order effects, and estimate heritabilities (proportion of observed variance due to genetic influences). Non-spatial alternation (NSA), which may involve greater reliance on processing of subgoals, was significantly more difficult than spatial alternation (SA). Despite their similarities, NSA and SA scores were uncorrelated. NSA performance was worse when administered second; there was no SA order effect. NSA scores were modestly heritable (h(2)=.25; 26); SA was not. There was shared genetic variance between NSA scores and general intellectual ability (r(g)=.55; .67), but this also suggests genetic influences specific to NSA. Compared with findings from small, selected control samples, high "failure" rates in this community-based sample raise concerns about interpretation of brain dysfunction in elderly or patient samples.  相似文献

Previous research has demonstrated a female advantage, albeit imperfectly, on tests of object location memory where object identity information is readily available. However, spatial and visual elements are often confounded in the experimental tasks used. Here spatial and visual memory performance was compared in 30 men and 30 women by presenting 12 abstract designs in a spatial array for recall and recognition (visual memory) and spatial location ("object" location memory). Object location memory was measured via a sensitive absolute displacement score defined as the distance in mms between the position assigned to the object during recall and the actual position it originally occupied. There were no sex differences in either the visual or spatial location tests. Controlling for age and estimated IQ scores made no impact on the results. These data suggest an absence of a sex difference in purely visual and spatial aspects of object location memory.  相似文献

Paranoia has been hypothesized to be negatively correlated with self‐esteem. However, hypotheses differ about how low self‐esteem might produce paranoia. The paranoia as defense model views paranoia as a defensive reaction against low self‐esteem. In contrast, the paranoia as expression model views paranoia in part as a reflection of low self‐esteem. In the current study, paranoia was negatively associated with global explicit self‐esteem, self‐competence, self‐liking and self‐serving attributional style, but unassociated with implicit self‐esteem as measured with the Implicit Association Test. In contrast, facets of narcissism, which also have been hypothesized to be associated with defensive self‐processing, were associated with defensiveness. Overall, these results suggest that paranoia is better represented by the expression model. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

The aim of this study was to examine occurrence of romantic relationships and relationship break‐ups among young adults in Hong Kong and Australia and to explore associations between relationship style, identity status, negative affect, cultural group, and relationship experiences. Data were collected from Chinese tertiary students in Hong Kong (n = 279) and Anglo‐Australian tertiary students in Melbourne, Australia (n = 204). Participants completed a questionnaire including demographics, romantic relationship items, the Love Schemas Scale measuring romantic relationship style, the Extended Objective Measure of Ego Identity Status, and the Depression Anxiety Stress Scale. Secure relationship style and more mature identity statuses were associated with having had a romantic relationship. Among those young people with romantic relationship experience, break‐ups were less common for those with a foreclosed identity status, skittish (avoidant) relationship style, and Hong Kong Chinese background. Negative mood was higher among those for whom a break‐up had been recent. Hurt experienced following a break‐up was greater when the break‐up was partner initiated and among those with less secure relationship styles and identity statuses. Overall, individual factors were stronger predictors of relationship status than cultural factors.  相似文献

Abstract

The causes cited by 218 participants for the hypothetical positive and negative life events on the Attributional Style Questionnaire (ASQ) and the dimensional ratings of the causes were examined to determine the match between the dimensional and categorical definitions of attributional style. Optimists (n = 105) and pessimists (n = 113) used different types of causes to explain the negative ASQ events, but not the positive events. However, optimists' and pessimists' causal explanations shared a number of features. The findings suggest that attributional styles depend, in part, on the event being explained and demonstrate that the ASQ events elicit specific types of causes.  相似文献
