Kindergarten Ss were presented with 16 pictorial items in four category sets or a partially random ordem with one item from each category composing the four presentation sets. The pictures were presented either on conceptually related background pictures or on white backgrounds. The categorically grouped presentation facilitated free recall performance, both in terms of number of items recalled and the speed with which the items were recalled, and increased the amount of clustering in recall. Categorical clustering in recall was associated with shorter within- than between-category intervals and for those Ss who recalled items from each of four categories successively, the over-all temporal pattern in recall closely approximated that found with adults. No background effects were found. 相似文献

k-SAT is a fundamental constraint satisfaction problem. It involvesS(m), the satisfaction set of the conjunction of m clauses,each clause a disjunction of k literals. The problem has manytheoretical, algorithmic and practical aspects. When the clauses are chosen at random it is anticipated (butnot fully proven) that, as the density parameter m/n (n thenumber of variables) grows, the transition of S(m) to beingempty, is abrupt: It has a "sharp threshold", with probability1 o(1). In this article we replace the random ensemble analysis by apseudo-random one: Derive the decay rule for individual sequencesof clauses, subject to combinatorial conditions, which in turnhold with probability 1 o(1). This is carried out under the big relaxation that k is not constantbut k = log n , or even r log log n . Then the decay of S isslow, "near-perfect" (like a radioactive decay), which entailssharp thresholds for the transition-time of S below any givenlevel, down to S = . 相似文献

A paradox at the heart of language acquisition research is that, to achieve adult‐like competence, children must acquire the ability to generalize verbs into non‐attested structures, while avoiding utterances that are deemed ungrammatical by native speakers. For example, children must learn that, to denote the reversal of an action, un‐ can be added to many verbs, but not all (e.g., roll/unroll; close/*unclose). This study compared theoretical accounts of how this is done. Children aged 5–6 (N = 18), 9–10 (N = 18), and adults (N = 18) rated the acceptability of un‐ prefixed forms of 48 verbs (and, as a control, bare forms). Across verbs, a negative correlation was observed between the acceptability of ungrammatical un‐ prefixed forms (e.g., *unclose) and the frequency of (a) the bare form and (b) alternative forms (e.g., open), supporting the entrenchment and pre‐emption hypotheses, respectively. Independent ratings of the extent to which verbs instantiate the semantic properties characteristic of a hypothesized semantic cryptotype for un‐ prefixation were a significant positive predictor of acceptability, for all age groups. The relative importance of each factor differed for attested and unattested un‐ forms and also varied with age. The findings are interpreted in the context of a new hybrid account designed to incorporate the three factors of entrenchment, pre‐emption, and verb semantics. 相似文献

According to some philosophers who accept a propositional conception of evidence, someone's evidence includes a proposition only if it is true. I argue against this thesis by appealing to the possibility of knowledge from falsehood. 相似文献

Religion can play a positive role in preventing all types of abuse. Consequently, it is often difficult to believe that religion or a particular manner of religious awareness can also be conducive to the degradation and humiliation of individuals, and that it can be maneuvered to justify abusive behavior. In this article we discuss the emotional repercussions of religious-related abuse in the family, an aspect that is rarely documented in the field of psychotherapy, but has many negative consequences. Religious-oriented emotional abuse is traceable to several levels of human functioning: the individual's internal level of experiencing themselves, the interpersonal and systemic levels, where the individual enters relationships, as well as within the framework of the individual's relationship with God. 相似文献

In a study of the ratings of managers' behaviour made by themselves, their supervisors, subordinates, and peers, it was found that degree of similarity between self-ratings and ratings by colleagues was significantly associated with three aspects of rating content: the observability of a behaviour, its desirability, and the degree to which it concerned technical rather than interpersonal activities. However, these associations with rating content depended on which of two indices of between-rater similarity was studied, in terms of either the correlation or the difference between ratings. The desirability of behaviour more influenced correlation measures of similarity, and the type of behaviour had more influence on difference scores: managers over-rated their interpersonal activities but not their technical effectiveness. 相似文献

Previous research has indicated that the effects of in‐group social value on mental health are mediated by the extent to which individuals identify with their in‐group. Other research has shown that in‐group identification leads to positive mental health because it provides in‐group members with a psychological basis for social support. We examine how the individual's perception of the social value of the in‐group leads to positive mental health, integrating the effects of identification with and support from the in‐group. As predicted, the relationship between higher social value and decreased mental health (e.g. depression, perceived stressful events) is mediated by higher in‐group identification, which in turn leads the members to expect support from the in‐group but not the out‐group. An integrated model of the effects of perceived in‐group social value, identification, and support on mental health is proposed, and the implications are discussed. 相似文献

Self-harm behaviour traditionally has been associated with borderline personality disorder. In this study, we examined the relationship between borderline personality symptomatology and intentionally distancing oneself from God as self-punishment, based on the assumption that such self-punishment may represent a form of self-harm behaviour. Data from four previous samples of primary care outpatients collected over a two-year period were combined (N?=?1511). Borderline personality was assessed with two measures: the borderline personality scale of the Personality Diagnostic Questionnaire-4 (PDQ-4) and the Self-Harm Inventory (SHI). Point-biserial correlation coefficients revealed that those who endorsed distancing oneself from God as punishment scored relatively higher on both the PDQ-4 (r?=?0.40, p?<?0.001) and the SHI (r?=?0.46, p?<?0.001). Similarly, when compared to respondents who denied ever having distanced themselves from God as punishment, those who did were more likely to exceed the clinical cut-off score on the PDQ-4 (47.3% vs. 10.9%, X2 ?=?152.53, p?<?0.001) and the SHI (57.3% vs. 11.4%, X2 ?=?224.12, p?<?0.001). Findings support our hypothesis that distancing oneself from God as punishment may be a form of self-harm behaviour associated with borderline personality symptomatology. 相似文献

Two experiments assessed whether similarity between the two elements of a compound would influence the degree of mediated extinction versus recovery from overshadowing in human causal judgements. In both Experiments 1 and 2, we assessed the influence of extinguishing one element of a two-element compound on judgements about the other element. In Experiment 1 we manipulated the physical similarity of the two elements of the compound; in Experiment 2, we used equivalence and distinctiveness pretraining in order to vary their functional similarity. We found that these procedures influenced mediated extinction and recovery from overshadowing as a function of both physical and acquired similarity and distinctiveness, respectively. The implications of these results for previously reported differences between humans and nonprimate animals are discussed. 相似文献

Current theories of object recognition in human vision make different predictions about whether the recognition of complex, multipart objects should be influenced by shape information about surface depth orientation and curvature derived from stereo disparity. We examined this issue in five experiments using a recognition memory paradigm in which observers (N = 134) memorized and then discriminated sets of 3D novel objects at trained and untrained viewpoints under either mono or stereo viewing conditions. In order to explore the conditions under which stereo-defined shape information contributes to object recognition we systematically varied the difficulty of view generalization by increasing the angular disparity between trained and untrained views. In one series of experiments, objects were presented from either previously trained views or untrained views rotated (15°, 30°, or 60°) along the same plane. In separate experiments we examined whether view generalization effects interacted with the vertical or horizontal plane of object rotation across 40° viewpoint changes. The results showed robust viewpoint-dependent performance costs: Observers were more efficient in recognizing learned objects from trained than from untrained views, and recognition was worse for extrapolated than for interpolated untrained views. We also found that performance was enhanced by stereo viewing but only at larger angular disparities between trained and untrained views. These findings show that object recognition is not based solely on 2D image information but that it can be facilitated by shape information derived from stereo disparity. 相似文献
