The purpose of this study was to examine the extent to which working memory resources are recruited during statistical learning (SL). Participants were asked to identify novel words in an artificial speech stream where the transitional probabilities between syllables provided the only segmentation cue. Experiments 1 and 2 demonstrated that segmentation performance improved when the speech rate was slowed down, suggesting that SL is supported by some form of active processing or maintenance mechanism that operates more effectively under slower presentation rates. In Experiment 3 we investigated the nature of this mechanism by asking participants to perform a two-back task while listening to the speech stream. Half of the participants performed a two-back rhyme task designed to engage phonological processing, whereas the other half performed a comparable two-back task on un-nameable visual shapes. It was hypothesized that if SL is dependent only upon domain-specific processes (i.e., phonological rehearsal), the rhyme task should impair speech segmentation performance more than the shape task. However, the two loads were equally disruptive to learning, as they both eradicated the benefit provided by the slow rate. These results suggest that SL is supported by working-memory processes that rely on domain-general resources. 相似文献

Alcohol use is frequently involved in crime, making it crucial to understand the role of alcohol in facial recognition to maximize correct perpetrator identifications. Although the majority of the alcohol and face recognition research has investigated recognition with retrospective confidence judgments, we examined the effects of alcohol intoxication on face recognition with prospective metacognitive judgments. Participants (N = 54 university students without a history of hazardous alcohol/substance use) consumed either alcohol (mean breath alcohol concentration of 0.06 at pretest and 0.07 at post‐test) or a non‐alcoholic placebo drink. Participants then studied unfamiliar male and female faces and made judgments of learning (JOLs) for each face (i.e., predicted the likelihood of recognizing that face on a future memory test). After a brief distractor task, participants completed an old–new recognition test on which they attempted to distinguish the studied faces from new faces. It was found that the alcohol manipulation had minimal effect on face recognition performance or judgments of learning. Our results suggest that theory‐based cues about the effects of alcohol might play a greater role in retrospective judgments than prospective judgments. Although not a primary focus of the study, face recognition was better for male faces than female faces, and this occurred for both female and male participants. Limitations and implications of the research are discussed. 相似文献

Children's emotion dysregulation and depressive symptoms are known to be affected by a range of individual (parent, child) and systemic (parent–child, marital, and family) characteristics. The current study builds on this literature by examining the unique role of coparental affect in children's emotion dysregulation, and whether this association mediates the link between parent and child depressive symptoms. Participants were 51 mother–father–child triads with children aged 7 to 12 (M age = 9.24 years). Triads discussed a time when the child felt sad and a time when the child felt happy. Maternal and paternal displays of positive affect were coded, and sequential analyses examined the extent to which parents were congruent in their displays of positive affect during the emotion discussions. Results indicated that interparental positive affect congruity (IPAC) during the sadness discussion, but not the happiness discussion, uniquely predicted parent‐reported child emotion dysregulation, above and beyond the contributions of child negative affect and parental punitive reactions. The degree of IPAC during the sadness discussion and child emotion dysregulation mediated the association between maternal, but not paternal, depressive symptoms and child depressive symptoms. Findings highlight the unique role of coparental affect in the socialization of sadness in youth and offer initial support for low levels of IPAC as a risk factor for the transmission of depressive symptoms in youth. 相似文献

Parental ADHD symptomatology and related impairments have been robustly associated with youth ADHD across decades of work. Notably, these factors may impede typical development of child self-regulation capabilities through both neurobiological and interpersonal processes. High heritability of estimates for the disorder further suggest that these effects are likely genetically-mediated, at least in part. Variation within the dopamine D4 receptor gene (DRD4) has been shown to moderate parental influences on youth ADHD. Use of a multiplex family design (i.e., samples of families that included multiple affected members) may facilitate identification of additional gene variants of interest and advance understanding of gene-environment interplay in regard to parenting. Thirty multiplex families consisting of 114 individuals (66 youth, 48 parents) completed a multi-stage, multi-informant diagnostic and neurocognitive assessment, measures of parenting, and provided saliva samples for DNA analyses. Sanger sequencing of the DRD4 gene yielded 16 rare variants; a polygenic risk score was computed for both parents and youth. Generalized estimating equations (GEE) examined the predictive effects of parental ADHD symptoms, parental neurocognitive functioning, and poor parenting dimensions on youth ADHD as well as moderation of these effects by parental and youth DRD4 variants. Findings indicated that parental DRD4 variants moderated the impact of parental ADHD and neurocognitive functioning on youth ADHD symptoms. Youth DRD4 variants moderated the impact of parental inconsistent discipline on child ADHD. In all cases, stronger associations were observed for those individuals with more risk variants. These exploratory findings highlight the potential utility of a multiplex family design for examining the interplay between parent and child characteristics in predicting youth outcomes. 相似文献

Black Mountain College is remembered as an artistic utopian alternative to institutional learning. Its faculty and students included some of the most important creative thinkers of the 20th century. Its foundation was built on the philosophy of “learning by doing.” But what made Black Mountain such a dynamic educational environment? Today, the financial burden of higher education places a lasting strain on students that inhibits creative growth. Does the educational structure of the college system impede our learning? Black Mountain was a legendary educational experiment, which offers a model for contemporary art education. 相似文献

This study examined the role of anxiety sensitivity as an explanatory variable in the link between two temperamental dimensions (i.e., behavioral inhibition and negative affect) and anxiety disorder symptom severity in a sample of children with anxiety disorders. Forty-four children (52?% African American) between 8 and 12 years of age and their mothers participated in this study. An assessment battery consisting of diagnostic interviews, questionnaires, and behavioral assessment of behavioral inhibition was administered. Findings revealed that anxiety sensitivity was a significant explanatory variable linking child self-reports of behavioral inhibition and negative affect to anxiety disorder symptom severity. For parent-completed measures, only direct effects of behavioral inhibition on anxiety disorder symptom severity were found. The clinical implications of our findings, including the importance and feasibility of anxiety sensitivity and behavioral inhibition assessments as part of routine clinical care of children with anxiety disorders are discussed, along with the limitations of our study. 相似文献

Geoffrey Loftus, Editor of Memory & Cognition from 1994 to 1997, strongly encouraged presentation of figures with error bars and avoidance of null hypothesis significance testing (NHST). The authors examined 696 Memory & Cognition articles published before, during, and after the Loftus editorship. Use of figures with bars increased to 47% under Loftus's editorship and then declined. Bars were rarely used for interpretation, and NHST remained almost universal. Analysis of 309 articles in other psychology journals confirmed that Loftus's influence was most evident in the articles he accepted for publication, but was otherwise limited. An e-mail survey of authors of papers accepted by Loftus revealed some support for his policy, but allegiance to traditional practices as well. Reform of psychologists' statistical practices would require more than editorial encouragement. 相似文献

Researchers and educational writers provide many views on what characteristics and skills the college graduate should possess (P. D. Gardner, 1998). Given the rapidly changing nature of knowledge in all disciplines and the subjectivity of grading systems, we argue the best indicator of a successful college education is a student's ability to think complexly about difficult problems. In this paper we examine students' levels of intellectual development to inform our understanding of how college experiences affect students' abilities to think in complex ways about difficult problems. Using both qualitative and quantitative research techniques, we examine and compare the experiences of 19 senior college students who were rated at opposite ends of the Perry scheme of intellectual development. The 19 students were purposefully selected to represent the high and low ends of the Perry scale from an overall sample of 27 senior students at a large eastern university. Ten students from the original sample of 27 demonstrated the most advanced cognitive development with Perry scale ratings of 5–7. Nine students had Perry ratings below 4; this was the lowest rating represented in the sample. We examine the similarities and differences between these two sets of students' academic profiles, and their comments about their curricular experiences, and how the Perry scale reflects on these results. We then discuss how these similarities and differences relate to students' development of the desirable characteristics of a college graduate, implications for faculty and administrators, and the relationship of these results to prior studies using the Perry scheme. 相似文献
