The current study employed model-based cluster analysis in a sample of male adolescent offenders (n = 94) to examine subtypes based on psychopathic traits and anxiety. Using the Psychopathy Checklist: Youth Version (PCL:YV;
Forth et al. 2003) and the self-report Antisocial Process Screening Device (APSD; Caputo et al. 1999), analyses identified three clusters in males that varied in the severity of psychopathic traits (low, moderate, and high)
and anxiety. The high psychopathic group exhibited more negative personality traits and was judged to be at greater risk for
dangerousness whereas the low psychopathic group exhibited more positive personality traits and was judged to be at lower
risk for dangerousness. Implications regarding potential developmental differences between adolescent and adult psychopathy,
as well as treatment considerations are discussed. 相似文献

Many studies report chronic deficits in visual processing in children born preterm. We investigated whether functional abnormalities in visual processing exist in children born preterm but without major neuromotor impairment (i.e. cerebral palsy). Twelve such children (< 33 weeks gestation or birthweight < 1000 g) without major neuromotor impairment and 12 born full‐term controls were assessed at 8–12 years of age by means of ophthalmological assessment (visual acuity, colour vision, stereopsis, stereoacuity, visual fields, ocular motility, motor fusion), cognitive tests of visual‐motor, visual‐perceptual and visual‐spatial skills and pattern‐reversal visual evoked potentials (PR‐VEPs). All participants also underwent magnetic resonance imaging (MRI) of the brain and neuromotor assessments. No significant differences were found between the groups on the ophthalmological, visual cognitive, neurological, neuromotor or MRI measures. The P100 component of the PR‐VEP showed a significantly shorter latency in the preterm compared with the full‐term participants. Whilst this P100 finding suggests that subtle abnormalities may exist at the neurophysiological level, we conclude that visual dysfunction is not systematically associated with preterm birth in the context of normal neurological status. 相似文献

Thematic organization is the association of information that is observed within a given time frame or event, and taxonomic organization is characterized by class membership based on featural overlap. Research in cognitive psychology has suggested a developmental progression in preference from thematic organization to taxonomic organization, with a preference for taxonomic organization seen as cognitively more advanced. However, recent research has found thematic preferences in adults and shown that organizational preference can be influenced by context and experience. This study expanded on previous findings of individual differences and explored preferences across different domains. Specifically, preferences for knowledge organization were measured between student type (history and psychology) and across content type (general and history). The results indicated that history material was more likely to be organized thematically than general material. 相似文献

The purpose of this article is to discuss curriculum-based measurement (CBM) as it is currently utilized in research and practice and to propose a new approach for developing measures to monitor the academic progress of students longitudinally. To accomplish this, we first describe CBM and provide several exemplars of CBM in reading and mathematics. Then, we present the research context for developing a set of seven curriculum-based measures for monitoring student progress in math problem solving. The rationale for and advantages of using statistical equating methodology are discussed. Details of the methodology as it was applied to the development of these math problem solving measures are provided. 相似文献

Perceptual input changes constantly in an unpredictable fashion, often changing before our somewhat sluggish perceptual systems have adequately processed this input. This can give rise to source confusion—how do we know whether a given perceptual activation is due to the current input, or a previous input that had yet to be completely processed? We propose that activity‐dependent neural accommodation naturally limits this source confusion by suppressing items once they have been identified. We review behavioral paradigms from different literatures that measure the correlates of persistence and accommodation. Of the various accommodative mechanisms, we focus on synaptic depression, deriving a rate‐coded expression that can be used to produce accommodating dynamics in any neural network with real valued activation. We implement this expression in a hierarchical model of perception termed, “a neural mechanism for responding optimally with unknown sources of evidence” (nROUSE). This model can be viewed as a more detailed version of the more abstract ROUSE model of Huber, Shiffrin, Lyle, and Ruys (2001), which produces accommodated levels of feature evidence through an optimal calculation. We apply nROUSE to three short‐term priming experiments that manipulated prime duration. 相似文献

College students perceive their risks for negative outcomes from sexual behavior as lower than that of their peers. We examined whether similar biases would occur when undergraduates rated their own, their close friends', and the typical college student's attitudes regarding casual sex and sexual responsibility. Participants rated their own attitudes relative to all others' as the least permissive and most sexually responsible. Close friends' attitudes were rated as less permissive and more responsible than the average college student's. Finally, individuals with unrestricted sociosexual orientations and men attributed more permissive and less sexually responsible attitudes to both themselves and close friends than did individuals with restricted sociosexual orientations and women. These latter effects were absent when rating the typical college student. 相似文献

The aim of this study was to compare callous-unemotional (CU) traits versus the multidimensional psychopathy construct in their ability to predict future and stable antisocial behavior. At baseline, a community sample of 996 Cypriot 12-year old adolescents (52% girls) completed measures that tap conduct problems (CP) and psychopathic traits, including CU. CP, aggression, and substance use were self-reported at 1–3 year follow-ups. Youths were assigned to six mutually exclusive groups based on their baseline levels of CP and psychopathic traits. Youth with CP scoring high on all three psychopathic traits dimensions (Psychopathic Personality?+?CP) showed the most robust and highest risk for future and stable CP, aggression, and substance use, followed by youth who were high on all three psychopathic traits dimensions but displayed no concurrent CP (Psychopathic Personality Only) and CP youth with low levels of psychopathic traits (CP Only). Youth with CP who merely manifested callous-unemotional traits (Callous-Unemotional?+?CP) were only at risk for future CP. The findings suggest that the CU traits-based approach for subtyping children with CP is less informative compared to a subtyping approach using various psychopathic traits dimensions in predicting future and stable forms of various antisocial outcomes. These findings and their consistency with prior work indicate the need for additional research to examine the various psychopathic traits dimensions rather than focusing solely on CU traits, especially for CP subtyping purposes. 相似文献

This study examined relations among interpersonal, affective, and impulsive-irresponsible psychopathic traits, emotional capacities, and recidivism rates in 144 detained adolescents. Emotional skill was conceptualized using a range of constructs, including face and voice processing, emotional intelligence, and self-reported cognitive and affective empathy. In addition, the relation between these concepts and recidivism three years after the initial assessment was examined. Results indicated that interpersonal traits were positively associated with better facial identification of fearful faces, whereas affective traits were associated with worse facial identification of sad and happy faces as well as angry voices. Impulsive-irresponsible traits were associated with reduced emotional intelligence. Differential predictive utility of the three psychopathic traits dimensions was also evidenced. Findings highlight the need to consider the broad concept of psychopathy, but also its underlying dimensions. 相似文献

The collection of very large text sources has revolutionized the study of natural language, leading to the development of several models of language learning and distributional semantics that extract sophisticated semantic representations of words based on the statistical redundancies contained within natural language (e.g., Griffiths, Steyvers, & Tenenbaum, 2007 ; Jones & Mewhort, 2007 ; Landauer & Dumais, 1997 ; Mikolov, Sutskever, Chen, Corrado, & Dean, 2013 ). The models treat knowledge as an interaction of processing mechanisms and the structure of language experience. But language experience is often treated agnostically. We report a distributional semantic analysis that shows written language in fiction books varies appreciably between books from the different genres, books from the same genre, and even books written by the same author. Given that current theories assume that word knowledge reflects an interaction between processing mechanisms and the language environment, the analysis shows the need for the field to engage in a more deliberate consideration and curation of the corpora used in computational studies of natural language processing. 相似文献
