The objective was to validate Regulatory Sensory Processing Disorders’ criteria (DC:0-3R, 2005) using empirical data on the presence and severity of sensory modulation deficits and specific psychiatric symptoms in clinical samples. Sixty toddlers who attended a child mental health unit were diagnosed by a clinical team. The following two groups were created: toddlers with RSPD (N?=?14) and those with “other diagnoses in Axis I/II of the DC:0-3R″(OD3R) (N?=?46). Independently of the clinical process, parents completed the Infant Toddler Sensory Profile (as a checklist for sensory symptoms) and the Achenbach Behavior Checklist for ages 1?–5 (CBCL 1?–5). The scores from the two groups were compared. The results showed the following for the RSPD group: a higher number of affected sensory areas and patterns than in the OD3R group; a higher percentage of sensory deficits in specific sensory categories; and a higher severity of behavioral symptoms such as withdrawal, inattention, other externalizing problems and pervasive developmental problems in CBCL 1?–5. The results confirmed our hypotheses by indicating a higher severity of sensory symptoms and identifying specific behavioral problems in children with RSPD. The results revealed convergent validity between the instruments and the diagnostic criteria for RSPD and supported the validity of RSPD as a unique diagnosis. The findings also suggested the importance of identifying sensory modulation deficits in order to develop an early intervention to enhance the sensory capacities of children who do not fully satisfy the criteria for some DSM-IV-TR disorders. 相似文献

Conduct problems are among the most discussed behavioral problems during childhood and adolescence. Given their heterogeneity, in recent years, researchers on this topic have called for delineation of early-onset conduct problems on the basis of affective, interpersonal and behavioral traits that resemble adult psychopathy. The present study aims to analyze, from both a cross-sectional and longitudinal perspective, whether early psychopathic traits allow identification of a group of individuals defined by severe and persistent behavioral problems. To achieve this goal, data from a sample of 192 children (aged 6 to 11) were analyzed; from this sample, 133 children were followed-up in a new data collection that took place three years later. From the data obtained with the mCPS and CBCL (parents), and APSD and TRF (teachers), we observed that children who showed early psychopathic traits, also showed greater frequency, severity and persistence of conduct problems. These results suggest the need to take into account the role of psychopathic traits (particularly, affective and interpersonal) as risk factors to delimit the most serious and persistent patterns of externalizing behavior. 相似文献

How might artificial neural networks (ANNs) inform cognitive science? Often cognitive scientists use ANNs but do not examine their internal structures. In this paper, we use ANNs to explore how cognition might represent musical properties. We train ANNs to classify musical chords, and we interpret network structure to determine what representations ANNs discover and use. We find connection weights between input units and hidden units can be described using Fourier phase spaces, a representation studied in musical set theory. We find the total signal coming through these weighted connection weights is a measure of the similarity between two Fourier structures: the structure of the hidden unit's weights and the structure of the stimulus. This is surprising because neither of these Fourier structures is computed by the hidden unit. We then show how output units use such similarity measures to classify chords. However, we also find different types of units—units that use different activation functions—use this similarity measure very differently. This result, combined with other findings, indicates that while our networks are related to the Fourier analysis of musical sets, they do not perform Fourier analyses of the kind usually described in musical set theory. Our results show Fourier representations of music are not limited to musical set theory. Our results also suggest how cognitive psychologists might explore Fourier representations in musical cognition. Critically, such theoretical and empirical implications require researchers to understand how network structure converts stimuli into responses. 相似文献

Drawing on the proactive motivation model and theories of motivation, the current study examined customer-initiated support as an antecedent of employees’ proactive customer service performance (PCSP) and investigated the mediating role of proactive motivations and the moderating role of serving culture. We conducted two multilevel studies to test the proposed hypotheses. In study 1, we collected diary data from 158 nurses across 10 working days, and results showed that the relationship between nurses’ daily experience of customer-initiated support and their PCSP was mediated by self-efficacy, work meaning, and positive affect. In study 2, we collected multilevel multi-source data from 373 nurses nested within 80 units and found that nurses’ experience of customer-initiated support was positively related to their supervisor-rated PCSP via role-breadth self-efficacy and work meaning, but not through positive affect. Further, team-level serving culture strengthened the positive relationship between customer-initiated support and role-breadth self-efficacy. These findings shed light on understanding the effect of customer-initiated support as an external factor on prompting service employees’ proactive behaviors, potential motivational mediators to explain the underlying mechanisms, and potential boundary conditions inside of service organizations to strengthen the positive effects of customer-initiated support. 相似文献

Over the past decade, ethical leadership has increasingly become one of the most popular topics in the areas of leadership and business ethics. As a result, there now exists a substantial body of empirical research addressing ethical leadership issues, but the findings reported by this body of research are highly fragmented. The topic has advanced to the stage where a review and synthesis of existing literature can provide great value and help move the scholarly conversation forward. The primary purposes of this article are to (a) review empirical findings from the ethical leadership literature utilizing a framework consisting of the antecedents, mediators, moderators and outcomes of ethical leadership, and (b) suggest a set of interesting research opportunities, thereby facilitating future investigation. We base our synthesis on a review of 62 empirical studies on ethical leadership that were published between 2005 and mid-2015. 相似文献

Discontinuous precipitation in a two-phase Zn-rich Zn-6.3at.%Ag alloy has been studied. It has been shown that the eta/epsilon interphase boundaries have the ability to initiate discontinuous precipitation as do the eta/eta grain boundaries. The back-polishing method is used to show the interconnection between a discontinuous precipitate colony and the eta/epsilon interphase boundary. The reaction front velocity of discontinuous precipitation initiated at the eta/eta grain boundary is 12-90% higher than that of discontinuous precipitation initiated at the eta/epsilon interphase boundary under various ageing temperatures. 相似文献
