Epistemic luck has been the focus of much discussion recently. Perhaps the most general knowledge-precluding type is veritic
luck, where a belief is true but might easily have been false. Veritic luck has two sources, and so eliminating it requires
two distinct conditions for a theory of knowledge. I argue that, when one sets out those conditions properly, a solution to
the generality problem for reliabilism emerges.

Three experiments explored whether response mode differences in perspective taking result from different spatial representations or different retrieval processes. Participants learned object locations and then, while blindfolded, pointed to or verbally described object locations from perspectives aligned or misaligned with their facing direction and aligned or misaligned with the learning perspective. Pointing was facilitated from the perspective aligned with the body during testing. Similar facilitation occurred when verbally labeling, but only when conducted in the context of pointing (e.g., after pointing). Without this pointing context, or after third-person strategy instructions, the effect of body alignment was eliminated for verbal responses. Pointing was less responsive to context and strategy. Across all conditions, performance was facilitated for the learning perspective. Taken together, these experiments indicate that response mode differences are due to differences in the retrieval process, which varies with strategy, rather than differences in the organization of the underlying spatial memory. 相似文献

This paper describes a short-term longitudinal study of the relation between violent victimization in the community and peer rejection among 199 children (mean age = 9.02 years) attending two urban Los Angeles area elementary schools. We used a multi-informant approach to assess victimization by community violence, peer group victimization, peer rejection, and impairments in emotion regulation. These data were collected annually for two consecutive school years. Violent victimization in the community predicted later peer rejection after accounting for the effects of initial levels of peer rejection. Analyses indicated that this relation was mediated by deficient emotion regulation skills. In addition, we found evidence that victimization by community violence and peer rejection are reciprocally related over time. The developmental implications of these findings are discussed. 相似文献

This study of Israeli and American preadolescent children examined characteristics of friendship in 44 children with high-functioning autism spectrum disorder (HFASD) compared to 38 typically developing children (TYP), as they interacted with a close friend Participants were 8-12 years of age (HFASD: Israel, n = 24; USA, n = 20; TYP: Israel, n = 23; USA, n = 15), and were matched on SES, receptive language vocabulary, child age, and gender (each study group included one girl). Multidimensional assessments included: individual behaviors of target children and observed child-friend interactions during construction and drawing scenarios; target child's and friend's self-perceived mutual friendship qualities; and mother-reported characteristics (friendship's duration/frequency; friend's age/gender/disability status). Overall, children with HFASD displayed a number of differences on individual and dyadic friendship measures. Both age and verbal abilities affected friendship behaviors. Children with HFASD and their friends perceived friendship qualities similarly, suggesting that preadolescents with HFASD have capacities for interpersonal awareness. Between-group similarities also emerged on several complex social behaviors, suggesting that friendship follows a developmental trajectory in autism and may enhance social interaction skills in autism. 相似文献

This study examined child anxiety sensitivity and family environment as mediators of the relationship between (1) parent psychopathology
and anxiety sensitivity and (2) child anxiety in a community sample of 157 youths aged 7–18 years. Parents completed measures
of anxiety sensitivity, psychopathology, and family environment. Youths completed measures of anxiety sensitivity and anxiety.
One structural equation model was tested with child anxiety sensitivity as a mediator of (1) parent psychopathology and parent
anxiety sensitivity and (2) child anxiety. Mediation was found with respect to parent psychopathology but not anxiety sensitivity.
A second structural equation model was tested with family environment (conflict and control) as a mediator of (1) parent psychopathology
and parent anxiety sensitivity and (2) child anxiety. Mediation was found with respect to parent psychopathology and anxiety
sensitivity. Possible explanations for these pathways are discussed, including information transmission from parents to children,
modeling anxiety-based reactions, temperament, and isolation of children from anxiety-provoking situations. 相似文献

The implications of adult relational aggression in adults for personality pathology are poorly understood. We investigated the association between relational aggression and features of DSM-IV personality disorders and psychopathy in a sample of undergraduates (N = 220). In contrast to the childhood literature, we found no significant difference in relational aggression between men and women. Unlike overt aggression, which correlated about equally highly with features of all three personality disorder clusters, relational aggression correlated significantly more highly with features of Cluster B than Clusters A or C. In addition, even after controlling for overt aggression, relational aggression correlated significantly with features of psychopathy, although only with Factor 2 traits. With the exception of sadistic personality disorder features, gender did not moderate the relationship between relational aggression and personality pathology. Further research on the psycho-pathological implications of relational aggression in more severely affected samples is warranted. 相似文献

Twenty-seven monolingual and 27 bilingual children aged between 6 and 7 years were assessed using the core subtests of the NEPSY, a children's neuropsychological assessment. Bilingual children scored lower than monolingual children in the Language domain and their performance was comparable with the monolingual children in the domains of Attention/Executive Functioning, Sensorimotor, Visuospatial, and Memory. The NEPSY correlates well with measures of academic achievement. It is concluded that the NEPSY is relatively insensitive to cultural factors and appears to be insensitive to bilingualism in the neuropsychological assessment of bilingual children in the United Kingdom. 相似文献

The experiment reported here examined implicit memory function, as measured through repetition priming, in amnestic mild cognitive impairment (MCI) to examine whether impairments exist in this aspect of memory function. Young adults, healthy older controls, Alzheimer's disease patients, and MCI participants were asked to perform two types of implicit memory tests (word stem completion and threshold identification repetition priming tasks), as well as a recognition test for studied items. As expected, young adults performed better than the other participants on the recognition test and the word stem completion task; there was equivalent priming across groups on the word identification task. While both the older control and MCI participants showed lower levels of priming on the word stem completion task relative to the young adults, the magnitude of priming was equivalent for these two groups, and reliably greater than that of the dementia participants. These results suggest that not all aspects of memory function are impaired in MCI relative to healthy aging. 相似文献

Common marmosets (Callithrix jacchus jacchus), human children, and human adults learned to find a goal that was located in the center of a square array of four identical landmarks. The location of the landmark array and corresponding goal varied across trials, so the task could not be solved without using the landmark array. In Experiment 1, a matrix of discrete goal locations was presented and the landmarks surrounded and were adjacent to the correct location during training. After training, an expansion test was given in which the distance between landmarks was increased. Marmosets, children (ages 5–9), and adults all readily learned to use the landmarks to search accurately during training. On the expansion test, adults uniformly searched in the center of the array. Monkeys and children concentrated their searching near the landmarks rather than in the center. The monkeys, but not the children, searched more often on the directionally appropriate side of the landmarks than on other sides of the landmarks. In Experiment 2, children (ages 3–5) were trained with a continuous search space and with the goal farther from the landmarks so that a beaconing strategy rule could not be used. Several of the children failed to acquire the training task. Of those who learned to find the goal, three searched in the middle on expansion tests but most searched nearer to the landmarks. The “middle rule” strategy that is uniformly used by adult humans does not appear to be a preferred strategy for children or non-human primates. 相似文献
