Current associative theories of contingency learning assume that inhibitory learning plays a part in the interference between outcomes. However, it is unclear whether this inhibitory learning results in the inhibition of the outcome representation or whether it simply counteracts previous excitatory learning so that the outcome representation is neither activated nor inhibited. Additionally, these models tend to conceptualize inhibition as a relatively transient and cue‐dependent state. However, research on retrieval‐induced forgetting suggests that the inhibition of representations is a real process that can be relatively independent of the retrieval cue used to access the inhibited information. Consistent with this alternative view, we found that interference between outcomes reduces the retrievability of the target outcome even when the outcome is associated with a novel (non‐inhibitory) cue. This result has important theoretical implications for associative models of interference and shows that the empirical facts and theories developed in studies of retrieval‐induced forgetting might be relevant in contingency learning and vice versa. 相似文献

Research indicates that the extent to which one becomes engaged, transported, or immersed in a narrative influences the narrative's potential to affect subsequent story-related attitudes and beliefs. Explaining narrative effects and understanding the mechanisms responsible depends on our ability to measure narrative engagement in a theoretically meaningful way. This article develops a scale for measuring narrative engagement that is based on a mental models approach to narrative processing. It distinguishes among four dimensions of experiential engagement in narratives: narrative understanding, attentional focus, emotional engagement, and narrative presence. The scale is developed and validated through exploratory and confirmatory factor analyses with data from viewers of feature film and television, in different viewing situations, and from two different countries. The scale's ability to predict enjoyment and story-consistent attitudes across different programs is presented. Implications for conceptualizing engagement with narratives as well as narrative persuasion and media effects are discussed. 相似文献

Representing the spatial appearance of objects and scenes in drawings is a difficult task for young children in particular. In the present study, the relationship between spatial drawing and cognitive flexibility was investigated. Seven- to 11-year-olds (N = 60) were asked to copy a three-dimensional model in a drawing. The use of depth cues as an indicator of spatial drawing was examined. Furthermore, cognitive flexibility was assessed by three measures: the Wisconsin Card-Sorting Test 64 (reactive flexibility), the Five-Point Test (spontaneous flexibility), and omission/inclusion (representational flexibility). The results revealed significant relationships between all measures of flexibility and the depth cues in children's drawings. However, only spontaneous and representational flexibility turned out to be significant predictors of the spatial drawing score. The results are discussed in light of the specific requirements of spatial representations in drawings. 相似文献

Abstract Losses are often equated for conceptual purposes, and it is often assumed that different types of losses result in similar grief reactions and exert similar effects on cognitive structures and coping patterns. This article examines the expectancies, beliefs, coping patterns, and psychological adjustment associated with loss due to death, parental. divorce, or illness and disability in a college student population. Loss groups did not differ from each other or from a no-loss group on cognitive variables, coping, or psychological adjustment. In instances in which associations between the cognitive measures and either coping or adjustment were indicated, the typical pattern was for loss groups to differ from the no-loss condition but not from each other. 相似文献

The present study examined the factor structure of a widely used measure of parenting style in three samples from Northwestern India. College Students (n = 195) completed Parental Authority Questionnaire (PAQ; Buri in J Pers Assess 57:110–119, 1991), and mothers of children attending high-school (n = 275), and middle-school (n = 145) completed its parent-report version Parental Authority Questionnaire-Revised (PAQ-R; Reitman et al. in J Psychopathol Behav Assess 24:119–127, 2002). Preliminary findings revealed that across three samples Cronbach’s alpha values ranged from poor to acceptable, with permissive parenting subscale of the PAQ/PAQ-R having the lowest value, whereas the authoritarian parenting had the highest value. Confirmatory factor analysis revealed that none of the models achieved satisfactory fit (i.e., CFI > .90). Exploratory factor analysis revealed that a two factor structure (with first component consisting of authoritative and permissive items, and the second component consisting of authoritarian items) rendered Cronbach’s alpha in the acceptable range. Only PAQ/PAQ-R authoritarian scale was correlated with youth adjustment problems across all three samples, while findings concerning authoritative and permissive scales were mixed. The findings suggest that only PAQ/PAQ-R authoritarian scale is reliable and valid in urban, middle-class, educated families in India, and encourage researchers to develop culturally relevant measures of parenting for this population. 相似文献

The aim of this study was to investigate the accuracy of the Portuguese version of Addenbrooke’s Cognitive Examination–Revised (ACE-R) in detecting and differentiating early stage subcortical vascular dementia (SVD) from early stage Alzheimer’s disease (AD). Ninety-two subjects (18 SVD patients, 36 AD patients, and 38 healthy controls) were assessed using the ACE-R. Between-group’s differences were evaluated using the Quade’s rank analysis of covariance. The diagnostic accuracy and discriminatory ability of the ACE-R were examined via receiver operating characteristic (ROC) analysis. The ACE-R was able to successfully discriminate between patients and healthy subjects. The mean ACE-R total scores differed between SVD and AD patients; there were also significant differences in attention and orientation and in memory measures between the groups. An optimal cut-off of 72/73 was found for the detection of AD (sensitivity: 97%; specificity: 92%) and SVD (sensitivity: 100%; specificity: 92%). 相似文献

We report two experiments that investigate practice effects on Stroop color-word interference in older and younger adults. Both experiments employed a computerized, single-item version of the Stroop task with a voice response, and both involved practice over hundreds of trials. Both experiments showed generally similar practice patterns, including a practice-related reduction in the size of the color-word interference effect. However, the older group continued to show a larger interference effect throughout practice. These findings indicate that older adults show the same trend in practice-related improvement on the Stroop task as younger adults. 相似文献

ABSTRACT We investigated the feasibility of using the Space Fortress (SF) game, a complex video game originally developed to study complex skill acquisition in young adults, to improve executive control processes in cognitively healthy older adults. The study protocol consisted of 36 one-hour game play sessions over 3 months with cognitive evaluations before and after, and a follow-up evaluation at 6 months. Sixty participants were randomized to one of three conditions: Emphasis Change (EC) – elders were instructed to concentrate on playing the entire game but place particular emphasis on a specific aspect of game play in each particular game; Active Control (AC) – game play with standard instructions; Passive Control (PC) – evaluation sessions without game play. Primary outcome measures were obtained from five tasks, presumably tapping executive control processes. A total of 54 older adults completed the study protocol. One measure of executive control, WAIS-III letter–number sequencing, showed improvement in performance from pre- to post-evaluations in the EC condition, but not in the other two conditions. These initial findings are modest but encouraging. Future SF interventions need to carefully consider increasing the duration and or the intensity of the intervention by providing at-home game training, reducing the motor demands of the game, and selecting appropriate outcome measures. 相似文献

Sixty-eight percent of U.S. adults are overweight/obese, and this epidemic has physical, psychosocial, and behavioral consequences. An internet sample of adults (N = 2997) perceiving themselves as larger than ideal in clothing size reported their body mass index (BMI), relative clothing size (RS; discrepancy between current and ideal size), and avoidance behaviors. Exploratory factor analysis of 10 avoidance items produced social avoidance and body display avoidance factors. A relative importance analysis revealed RS as a better predictor than BMI for avoidance. A hierarchical multivariate analysis of covariance found RS to predict both avoidance constructs. The relationship between RS and both avoidance constructs was stronger for women than men, and for younger as compared to older participants. Caucasians reported more body display avoidance than African Americans. This suggests that personal dissatisfaction with body size may deter involvement in varied life events and that women are especially avoidant of activities that entail displaying their bodies. 相似文献

In two experiments we employed calibration methods to investigate the realism of participants' confidence ratings of their own classification performance based on knowledge acquired after training on an artificial grammar. In Experiment 1 participants showed good realism (but overconfidence) for grammatical strings but very poor realism for non-grammatical strings. Method of training (string repetition in writing or mere exposure) did not affect the realism. Furthermore, the participants underestimated their overall performance. In Experiment 2, using a more complex grammar and controlling for two types of associative chunk-strength, participants showed good realism (but still overconfidence) for both letter and symbol strings, irrespective of grammaticality. Together, these experiments show that implicit learning can give rise to knowledge products that are associated with fairly realistic meta-knowledge. It is argued that both the zero-correlation criterion and the guessing criterion are misplaced when used to define implicit knowledge; two reasons being that confidence judgements may be affected both by implicit knowledge and by inferences. 相似文献
