Gilovich, Vallone, and Tversky's (1985) analysis of basketball data indicates that a player's chances of making a shot are not affected by the results of earlier shots. However, their basketball data do not control for several confounding influences. An analysis of horseshoe pitching, which does not have these defects, indicates that players do have modest hot and cold spells. 相似文献

Participant-witnesses viewed a crime video and attempted to identify the culprit from a culprit-absent lineup. The 253 mistaken-identification eyewitnesses were randomly given confirming, disconfirming, or no feedback regarding their identifications. Feedback was immediate or delayed 48 hr, and measures were immediate or delayed 48 hr. Confirming, but not disconfirming, feedback led to distortions of eyewitnesses' recalled confidence, amount of attention paid during witnessing, goodness of view, ability to make out facial details, length of time to identification, and other measures related to the witnessing experience. Unexpectedly, neither delaying the measures nor delaying feedback for 48 hr moderated these effects. The results underscore the need for double-blind lineups and neutral assessments of eyewitnesses' certainty and other judgments prior to feedback. 相似文献

This paper summarizes a conference held at the National Institute of Child Health and Human Development on December 6-7, 1999, on self-injurious behavior [SIB] in developmental disabilities. Twenty-six of the top researchers in the U.S. from this field representing 13 different disciplines discussed environmental mechanisms, epidemiology, behavioral and pharmacological intervention strategies, neurochemical substrates, genetic syndromes in which SIB is a prominent behavioral phenotype, neurobiological and neurodevelopmental factors affecting SIB in humans as well as a variety of animal models of SIB. Findings over the last decade, especially new discoveries since 1995, were emphasized. SIB is a rapidly growing area of scientific interest to both basic and applied researchers. In many respects it is a model for the study of gene-brain-behavior relationships in developmental disabilities. 相似文献

Zeno's paradoxes of motion and the semantic paradoxes of the Liar have long been thought to have metaphorical affinities. There are, in fact, isomorphisms between variations of Zeno's paradoxes and variations of the Liar paradox in infinite-valued logic. Representing these paradoxes in dynamical systems theory reveals fractal images and provides other geometric ways of visualizing and conceptualizing the paradoxes. 相似文献

Differential rates of participation in three categories of risk behaviors (i.e., sexual activity, substance use, violence) were explored, comparing gang members to nonmembers, within a sample of 1,143 inner-city African American adolescent females. The relationship between gang membership and risk behavior also was examined, by exploring the association between a variety of microsystemic influences (e.g., gang, family, school) and participation in risk behaviors. MANOVA analyses indicated that gang members, relative to nonmembers, reported higher rates of participation in each of the three categories of risk behaviors. Stepwise linear regression analyses indicated that gang membership was the variable with the most consistent predictive ability, across all categories of risk, as it entered early in all equations and remained in all three final models after controlling for other statistically significant contextual variables. Findings suggest that intervention efforts aimed at reducing adolescent females' participation in sexual activity, substance use, and violence should consider the influence of gang membership on the participation in these behaviors. 相似文献

The incarceration of mentally ill youth is a serious problem not receiving the same attention as in adults. In this study, we examine the prevalence of psychopathology and level of behavioral symptomatology in incarcerated youth versus youth receiving community mental health services or hospitalization. We randomly recruited youth from middle South Carolina served by a local CMHC (n = 60), youth served by the state adolescent inpatient program (n = 50), and youth in the S.C. Dept. of Juvenile Justice facilities from the same region (n = 75). We used the DISC-PC 2.3 to evaluate DSM-III-R diagnoses and the CBCL and YSR to evaluate behavioral symptomatology. On the DISC, incarcerated youth had significantly higher mean number of diagnoses and symptoms than CMHC youth, but lower numbers than hospitalized youth. Level of caseness (at least one diagnosis) was 86% in hospital youth, 72% in incarcerated youth, and 60% in CMHC youth. The groups differed in CBCL mean total T, internalizing T, and externalizing T scores as well as mean YSR internalizing T scores. Our results indicate the comparability in level of psychopathology in incarcerated and community-treated populations of youth, and the need to develop diversionary programs to prevent the entry of such youth into the juvenile justice system. 相似文献

Interviews with 98 teachers from a variety of schools were used to develop a definition of spiritual health, and to establish how these teachers thought spiritual health might best be fostered and what hindered its development in the school curriculum. A recurring theme, which seemed to be coming through the comments from teachers in this study, was the very important role that teachers play in helping students develop relationships. This was of vital importance as spiritual health was seen as being reflected in the quality of relationships that students develop with themselves, others, the environment, and with a Transcendent Other. The characteristics of teachers most frequently mentioned as desirable for the promotion of spiritual health were classified as follows:
? caring, sensitive, personal approach;
? concern for individuals;
? committed to personal beliefs and values.
Investigation of these teacher characteristics showed variation by gender, personal view of spiritual health, major curriculum concern, teacher and school type. Implications of these variations are discussed in this paper, together with the role of Spiritual Facilitator, to help nurture students' spiritual health. 相似文献

Neuropsychological characteristics and test behaviors of boys with early onset conduct problems. 总被引:6,自引:0,他引:6

School-age children and adolescents with conduct problems typically exhibit deficits in verbal IQ, language abilities, and executive functions. This study examined the extent to which this pattern was evident in a clinic group of preschool boys with early onset conduct problems who met criteria for oppositional defiant disorder (ODD) with and without attention deficit hyperactivity disorder (ADHD). A 2nd question focused on the strength of relation between clinic boys' uncooperative or inattentive test behaviors and their test performance. As expected, the clinic boys showed a neuropsychological profile highly similar to the one found in older conduct problem populations. Verbal tests distinguished clinic from matched comparison boys even after controlling for observers' ratings of disruptive behavior during testing. Clinic boys with ODD and ADHD had lower verbal and executive function scores than clinic boys with ODD alone. After general vocabulary knowledge and test behavior were controlled, clinic boys were found to have poorer vocabularies for describing affective states than comparison group boys. 相似文献

This paper reviews the current debate between differentiation and attachment in treating couples through exploring the tenets of crucible therapy (Schnarch, 1991) and emotionally focused couple therapy (Johnson, 2004). We provide a review of the two theories—as well as the two “pure form” example models—and explore the debate in light of the integrative movement in couple and family therapy (Lebow, 2014). We also examine points of convergence of the two theories and models, and provide clinicians and researchers with an enhanced understanding of their divergent positions. Both differentiation and attachment are developmental theories that highlight the human experience of balancing individuality and connection in adulthood. The two models converge in terms of metaconcepts that pervade their respective theories and approach. Both models capitalize on the depth and importance of the therapeutic relationship, and provide rich case conceptualization and processes of therapy. However, they substantially differ in terms of how they view the fundamental aspects of adult development, have vastly divergent approaches to how a therapist intervenes in the room, and different ideas of how a healthy couple should function. In light of the deep polarization of the two models, points of integration—particularly between the broader theories of attachment and differentiation—are offered for therapists to consider. 相似文献

Found in Translation: Late Bilinguals Do Automatically Activate Their Native Language When They Are Not Using It 下载免费PDF全文
In their paper “Do Bilinguals Automatically Activate Their Native Language When They Are Not Using it?”, Costa, Pannunzi, Deco, and Pickering (Cognitive Science, 2017) proposed a reinterpretation of Thierry and Wu's (2004, 2007) finding of native language‐based (Chinese, L1) ERP effects when they tested Chinese–English late bilinguals exclusively in their second language (English, L2). Using simulations in a six‐node Hebbian learning model (three L1 nodes, three L2 nodes), Costa et al. suggested that form overlaps in L1 between otherwise unrelated words create a persistent relationship between their L2 translations. In this scenario, words in the nascent L2 lexicon overlapping in their L1 translations would become linked during learning because of the form overlap in L1; once the L2 words are learned, the direct link between them would be sufficient to generate robust, apparently “L1‐mediated” priming without requiring any activation of L1 translations. Costa et al. contend that links between L2 words remain beyond the learning phase, even after links to L1 representations have been severed, and thus that their model affords an alternative account to (but not a rebuttal of) Thierry and Wu's claim of language non‐selective activation—or automatic activation of translation equivalents—in late bilinguals. In this response, we build on Costa et al.'s original simulation code, showing that it can only reproduce L1‐independent priming when implementing the L1 disconnection in their particular way. By contrast, when severing inter‐language connections bidirectionally, their model fails to retain any sizeable influence of L1 form overlap on L2 activations. The model is not the theory, however, and we discuss several issues that would need to be addressed in further attempts to model language non‐selective activation in late bilinguals. 相似文献
