The present study, including children at risk for developing Attention Deficit Hyperactivity Disorder (ADHD), examined the idea that complex executive functions (EFs) build upon more simple ones. This notion was applied in the study of longitudinal interrelations between core EF components — simple and complex inhibition, selective attention, and working memory (WM) — at age 5 and 6 as well as their predictive relations to ADHD symptoms at age 7. The results showed that simple inhibition and selective attention at age 5 independently predicted complex inhibition and WM at age 6. In addition, EFs primarily predicted symptoms of inattention rather than hyperactivity/impulsivity even at this young age. Finally, age 6 complex inhibition was shown to act as a mediator in the relations between simple inhibition and selective attention at age 5 and symptoms of inattention at age 7. These findings provide novel longitudinal support for the theory that fundamental EF components show a progression with age toward more complex executive control (see Garon et al. Psychological Bulletin 134(1):31–60 2008). Further, complex inhibition, implicating both inhibition and WM, seems to be a particularly strong correlate of ADHD symptoms in young children and should as such be the focus of future studies examining the relation between cognitive function and ADHD symptoms from a developmental perspective.  相似文献

Adolescent depression is a major public health concern. Depression and depressive symptoms are more prevalent in adolescent females and are associated with high-risk sexual behavior. Only one third of adolescents receive professional help for their depression, although about 90% visit their primary care providers on average 2–3 times per year. It is imperative that health professionals seek additional methods in the identification and treatment of depressive symptoms. This paper presents findings of the presence of clinically significant depressive symptoms in African American female adolescents receiving routine health care services within an adolescent primary care reproductive health clinic. Results revealed higher rates of depressive symptoms in this subsample of African American adolescent females when compared to the national sample, suggesting that primary care reproductive health clinics are a viable setting for the identification of depressive symptoms among low income, African American female adolescents. Psychosocial interventions and recommendations for the integration of primary care reproductive health, and behavioral health consultation services are presented.  相似文献

The study of formal theories of agents has intensified over the last decade since such formalisms can be viewed as providing the specifications for building agent-based systems. One such theory views agents as having beliefs, desires and intentions (BDI). The BDI paradigm provides us with the means of describing different types of agents; a desirable quality, since agent-based systems are employed in various domains with diverse characteristics and therefore different requirements. This is accomplished by adopting a set of constraints that describe how the three attitudes are related to each other, called a notion of realism. Although three such notions have been explored in the literature, namely strong realism, realism and weak realism, no systematic attempt has been undertaken to study other available options. In this paper we explore the dynamics and possible interrelations between the three attitudes and we propose notions of realism for heterogeneous BDI agents. We explore a wider range of possibilities by considering a combination of the types of relations between accessible worlds. Moreover, we distinguish between two broad categories of agents, bold and circumspect, according to the relation between beliefs and intentions. We explore several interesting notions of realism for such agents and we argue that these come close to the desiderata for rational BDI agents.  相似文献

The theoretical tenets of academic engagement, as outlined by Schaufeli and colleagues, have received limited attention. There is credence to indicate that Schaufeli et al.'s conceptualization has educational implications. Extending this avenue of inquiry, we report two longitudinal studies that explore the motivation‐related attributes of engagement within the framework of self‐efficacy. A number of research questions were developed for examination—for example, does enactive learning experience influence academic achievement, via students' engrossment (i.e. absorption) of a subject matter? Does students' sense of resilience and persistence (i.e. vigor) heighten their self‐efficacy beliefs for academic learning? For the two studies (Study 1: 311 Year 11 students; Study 2: 249 Year 12 students), utilizing different cohorts, we measured these constructs at multiple time points. Existing Likert‐scale inventories were administered repeatedly, and data collected were analysed using causal modeling procedures. MPlus 7.2 yielded a number of key findings—for example: (a) the positive impact of Time 1 enactive learning experience on Time 2 absorption and vigor, (b) the positive impact of Time absorption on Time 3 self‐efficacy, (c) the positive impact of Time 2 absorption on Time 4 achievement and (d) the positive impact of Time 1 self‐efficacy on Time 2 absorption and vigor.  相似文献

Many young children are reared today in both family and child-care settings. The relation that exists between these two settings has important implications for child care. Bronfenbrenner's (1979) ecological model is used as a way to view the interrelations among children, families, and child-care programs. Data from a study of infants in day care provide information on the time infants spend in family and day-care contexts, how parents and caregivers view children's behavior in these two settings, and rates of otitis media (ear infections) and other illnesses for these children. Results show that infants spend about twice as many hours per day awake with parents as in day care. Regarding child behaviors, parents and caregivers seem to have similar behaviors they like and dislike, but they each see particular children quite differently with respect to these behaviors. Finally, infants in this sample were diagnosed with illnesses 60% to 70% of the time. Findings are discussed in terms of the ecological model with particular attention given to relations between parents and caregivers.  相似文献

The present article discusses advances in psychotherapy research with children and adolescents. Effective intervention extends beyond identifying treatment techniques. Understanding the scope of dysfunctions and threats to adjustment and the course of development are central. Three central themes are highlighted. First, the scope of clinical dysfunctions, at-risk behavior, and conditions to which children are exposed are discussed. Second, the role of development in adjustment is illustrated by examples of research on negative affect, social behavior, and empathy. Finally, advances in psychotherapy outcome research are described with illustrations of treatment applications in the schools. The importance of treatment informed by developmental theory and the role of the school in identifying dysfunction and intervening are discussed in light of current advances in research.  相似文献

Berlyne, D. E. Interrelations of verbal and non-verbal measures used in experimental aesthetics. Scand. J. Psychol., 1973, 14, 177–184.MdashIn Experiment I, 40 miscellaneous visual patterns were rated on 12 scales. Factor analysis of correlations over patterns indicates three factors, provisionally labeled Complexity-Uncertainty. Hedonic Value, and Cortical Arousal. Factor loadings and significant differences among estimated factor scores are discussed with special reference to (1) relations with Osgood's dimensions (2) scales indicative of pleasure and discomfort and (3) scales indicative of arousal. Experiment II measured looking time. Relations between this measure and verbal judgments are examined.  相似文献

Both shared and unique genetic risk factors underlie the two symptom domains of attention deficit hyperactivity disorder (ADHD): inattention and hyperactivity-impulsivity. The developmental course and relationship to co-occurring disorders differs across the two symptom domains, highlighting the importance of their partially distinct etiologies. Familial cognitive impairment factors have been identified in ADHD, but whether they show specificity in relation to the two ADHD symptom domains remains poorly understood. We aimed to investigate whether different cognitive impairments are genetically linked to the ADHD symptom domains of inattention versus hyperactivity-impulsivity. We conducted multivariate genetic model fitting analyses on ADHD symptom scores and cognitive data, from go/no-go and fast tasks, collected on a population twin sample of 1,312 children aged 7–10. Reaction time variability (RTV) showed substantial genetic overlap with inattention, as observed in an additive genetic correlation of 0.64, compared to an additive genetic correlation of 0.31 with hyperactivity-impulsivity. Commission errors (CE) showed low additive genetic correlations with both hyperactivity-impulsivity and inattention (genetic correlations of 0.17 and 0.11, respectively). The additive genetic correlation between RTV and CE was also low and non-significant at ?0.10, consistent with the etiological separation between the two indices of cognitive impairments. Overall, two key cognitive impairments phenotypically associated with ADHD symptoms, captured by RTV and CE, showed different genetic relationships to the two ADHD symptom domains. The findings extend a previous model of two familial cognitive impairment factors in combined subtype ADHD by separating pathways underlying inattention and hyperactivity-impulsivity symptoms.  相似文献

We attempted to disentangle the interrelations between hopelessness, loneliness, and suicidal ideation, by comparing two conceptually driven models of their relationships, prospectively among 234 undergraduates, using a series of multiple regression/correlation equations. Model 1 framed loneliness as a risk factor for future suicidally that operates via its influence on hopelessness (the mediational view). Model 2 viewed hopelessness as a source variable that is predictive of both loneliness and suicidally, and postulated no relation between loneliness and suicidality beyond hopelessness. Model 2 received support, whereas Model 1 did not. We discuss the implications of our findings for the nomological status of hopelessness and loneliness as correlates of suicidality, and for exploration of the structural interrelations of suicide-related variables in general.  相似文献

Meng and Bader have presented evidence that a Case conflict is a more effective cue for garden-path reanalysis than a number conflict is, for German wh-sentences with subject–object ambiguities. The preferred first-pass analysis has the wh-trace in subject position, although object position is correct. In a speeded grammaticality judgment task, perceivers accepted Case-disambiguated examples more often and more rapidly than number-disambiguated examples, although comprehension questions indicated that both were eventually understood correctly. For ungrammatical sentences, a Case mismatch error resulted in more false positive grammaticality judgments than a number mismatch error. We offer an explanation for why Case and number features differ in these two ways in their effects on sentence processing. We propose, within the Diagnosis Model of garden-path processing, that reanalysis triggered by a Case mismatch guides the parser more effectively toward the correct structure. Case is a positive symptom, which carries information about the new structure that must be built. By contrast, a number mismatch is a negative symptom; it invalidates the incorrect structure without showing how to rebuild it. This difference in the transparency of garden-path repair can also account for the greater overacceptance of Case-disambiguated ungrammatical sentences. The speeded grammaticality judgment task is designed to encourage hasty responses. Usually, these are hasty rejections of garden path sentences that, on calmer reflection, the parser would find acceptable. Conversely, over-hasty acceptance could occur if some initial progress is made in resolving a grammatical problem. Thus, a higher rate of false positives on ungrammaticals is to be expected where reanalysis proceeds successfully for a while before blocking.  相似文献

PTSD symptoms related to school bullying have rarely been investigated, and never in national samples. We used data from a national survey to investigate this among students from grades 8 and 9 (n?=?963). The prevalence estimates of exposure to bullying were within the range of earlier research findings. Multinomial logistic regression showed that boys were 2.27 times more likely to be exposed to frequent bullying than girls. A latent variable second-order model demonstrated an association between frequency of bullying exposure and PTSD symptoms (beta?=?0.49). This relationship was not moderated by gender. However, the average levels of PTSD symptoms as well as clinical range symptoms were higher for girls. For all bullied students, 27.6% of the boys and 40.5% of the girls had scores within the clinical range. A mimic model showed that youth who identify as being both a bully and a victim of bullying were more troubled than those who were victims only. Our findings support the idea that exposure to bullying is a potential risk factor for PTSD symptoms among students. Future research could investigate whether the same holds for PTSD through diagnostic procedures, but this will depend on whether or not bullying is decided to comply with the DSM-IV classification of trauma required for diagnosis. Results are discussed with regard to their implications for school interventions.  相似文献

Prolonged grief disorder, characterized by severe, persistent and disabling grief, has recently been added to the DSM-5-TR and ICD-11. Treatment for prolonged grief symptoms shows limited effectiveness. It has been suggested that prolonged grief symptoms exacerbate insomnia symptoms, whereas insomnia symptoms, in turn, may fuel prolonged grief symptoms. To help clarify if treating sleep disturbances may be a viable treatment option for prolonged grief disorder, we examined the proposed reciprocal relationship between symptoms of prolonged grief and insomnia. On three time points across 6-month intervals, 343 bereaved adults (88% female) completed questionnaires to assess prolonged grief, depression, and insomnia symptoms. We applied random intercept cross-lagged panel models (RICLPMs) to assess reciprocal within-person effects between prolonged grief and insomnia symptoms and, as a secondary aim, between depression and insomnia symptoms. Changes in insomnia symptoms predicted changes in prolonged grief symptoms but not vice versa. Additionally, changes in depression and insomnia symptoms showed a reciprocal relationship. Our results suggest that targeting insomnia symptoms after bereavement is a viable option for improving current treatments for prolonged grief disorder.  相似文献

The present study was conducted with 549 women and men who were employed in gender-typical occupations or who were in vocational training, further qualification, or retraining for one of these job. We examined whether a gender-typical occupation is related to gender-role conflicts of women and men in work settings and whether self-esteem moderates the experiences of conflict. Generally, we cannot confirm influence of gender-typical jobs on experience of conflict. The results, however, supply evidence for the fact that women experience higher gender-role conflicts than men in all occupations. Women and men of low self-esteem engaged in typically female occupations experience especially high gender-role conflict.  相似文献

A clear differentiation between artists and nonartists was found in both formal quantitative and informal qualitative analyses. The results of the present study lend statistical support to the discriminatory power of the Rorschach in identifying artistic creativity. Artists and nonartists were carefully matched as to sex, age, verbal intelligence and education. The Rorschach Group Method was utilized to compare the two groups on all formal scoring categories of both the Klopfer and Beck systems. In addition to formal scoring, possible discriminating aspects in the verbalization of responses were analyzed qualitatively.  相似文献
