Children with perinatal arterial ischemic stroke (PAIS) have increased rates of attention and executive functioning (EF) weaknesses. Research in other pediatric disorders has documented poor consistency between parent report of these skills and performance-based measures. We compared these data sources in children with PAIS. Forty full-term (≥37 weeks) children ages 3–16 (median = 7.2 years; 58% male) with PAIS completed neuropsychological testing and composite scores were created for seven attention and EF domains (Processing Speed; Attention; Working Memory; Verbal Retrieval; Inhibitory Control; Flexibility/Shifting; Planning). Parents completed “real-world” functioning questionnaires (ADHD Rating Scale-IV, BRIEF). Correlational analysis were used to compare parent and performance measures. Correlations between ADHD Rating Scale-IV scores and the performance-based Attention and Inhibition composite scores were nonsignificant. Significant negative correlations were found between the BRIEF GEC and performance-based Verbal Retrieval and Processing Speed composites, but remaining GEC/composite comparisons were nonsignificant. Analyses between parent report BRIEF index scores and the corresponding performance-based domain identified one significant negative correlation between the BRIEF Working Memory Index and the Working Memory composite score. While children with PAIS demonstrate difficulties in attention and EF on both parent report and performance measures, little significance was found in comparisons of these two types of measures. There may be several explanations for this dissociation: measures assessing different aspects of the same underlying construct; performance-based measures lacking ecological validity; and parents underestimating/underreporting their child’s deficits. Thus, multiple sources of informant and performance data are necessary to make more accurate conclusions about functioning in these domains.  相似文献

Whereas a growing interest in the development of attentional flexibility (AF) and in perseverative behavior, being one marker of this component, exists in neuropsychological studies and in the domain of developmental psychopathology (e.g., PKU, infantile schizophrenia, autism and Parkinson's disease) (Pennington &; Ozonoff, 1996 Pennington, B. and Ozonoff, S. 1996. Executive functions and developmental psychopathology. Journal of Child Psychology and Psychiatry, 37: 5188. [PUBMED][INFOTRIEVE][CSA][Crossref], [PubMed], [Web of Science ®] [Google Scholar]; Stahl &; Pry, 2002 Stahl, L. and Pry, R. 2002. Joint attention and set-shifting in young children with autism. Autism, 6(4): 383396. [PUBMED][INFOTRIEVE][CROSSREF][Crossref], [PubMed], [Web of Science ®] [Google Scholar]), only a few studies have concerned themselves with this subject in normal children. It is thus of interest to add more empirical data to the existing literature in this domain. Therefore, the aim of our study was to explore the development of AF and of perseverative errors in young preschool children with normal development, aged 1.5 to 6 years. Using set-shifting tasks of increasing difficulty level, three age groups were compared with respect to their AF skills.Results show a developmental factor underlying AF, with different levels of this form becoming more and more complex with age, ranging from a rudimentary visual form to a complex representational form of flexibility. Overall, few perseverative errors occurred and they decreased with age. Results are discussed from a developmental and neuropsychological perspective.  相似文献

The Dark Triad traits—Machiavellianism, narcissism, and psychopathy—are theorized to facilitate short-term, exploitative social tactics. Thus, the Dark Triad traits should be positively related to (a) similar short-term-focused traits such as impulsivity and sensation-seeking, and (b) risky behaviors. In two studies (N > 1400), we examined the relationships among the Dark Triad traits and impulsivity and sensation-seeking. In Study 2, we incorporated risk behaviors, including blackjack betting and temporal discounting of money. Both studies showed positive relationships among the Dark Triad traits and impulsivity and sensation-seeking. Study 2 showed positive relationships among the Dark Triad traits, blackjack betting, and steeper temporal discounting. An experimentally manipulated ego threat in Study 2 marginally moderated the narcissism–discounting relationship; ego-threatened participants had a significantly positive relationship, whereas those who were not threatened showed no relationship. We discuss implications of the Dark Triad traits for understanding risk behavior.  相似文献

Abstract

Coparenting – how couples relate to one another in their joint roles as parents – is predictive of a wide variety of family and child outcomes. The current study used a qualitative, phenomenological approach to understand how couples negotiate the coparenting relationship during the transition to parenthood. The principal researcher interviewed 16 men and women of eight heterosexual, dual-earning, new parent couples. Themes emerged which were both conducive to successful coparenting and inhibitive of successful coparenting. Gender distinctions emerged between men and woman in their experiences of coparenting negotiation. Clinical implications of the themes are discussed.  相似文献

Resumen

Sperber y Wilson (1986, 1987) ban propuesto un modelo psicológico que incorpora las implicaturas en los procesos pragmáticos de comprensión del lenguaje.

Los objetivos del trabajo eran: 1) Determinar empíricamente la realidad psicológica de las implicaturas conversacionales mediante un paradigma experimental nuevo; 2) Contrastar la hipótesis de Sperber y Wilson de que intervienen procesos lógicos en la comprensión no natural de interacciones lingüísticas.

A 120 sujetos se les presentaron dos conjuntos de estímulos lingüísticos: 32 interacciones conversacionales de pregunta-respuesta indirecta y 32 implicaturas que correspondían a las proposiciones lógicas a las que, supuestamente, deberían acceder para comprender las interacciones. Se medía el tiempo (en centésimas de segundo) que empleaban los sujetos en dar una respuesta de aceptación/rechazo a las interacciones y en verificar la veracidad o falsedad de las implicaturas.

Los resultados son favorables a la hipótesis de la realidad psicológica de las implicaturas conversacionales en la comprensión de las interacciones lingüísticas de carácter indirecto. Además, son compatibles con la hipótesis de que en tales procesos se efectúan funciones cognitivas de verificación, lo que constituye un apoyo empírico favorable al modelo de Sperber y Wilson (1986, 1987).  相似文献

There is a growing body of evidence suggesting the potential role of disgust propensity in blood-injection-injury (BII) phobia. The current study examined associations between disgust propensity and BII phobia symptom severity in Caucasian Americans (n=310) and Asian Americans (n=223). Asian Americans typically scored higher than Caucasian Americans on the BII and disgust measures. The present study also examined the structural relations between gender, cultural background, disgust propensity, and BII phobia symptom severity. According to the structural equation model, disgust propensity was significantly related to levels of BII phobia symptom severity and fully mediated the relationships between BII phobia symptom severity and the demographic variables of gender and cultural background. The implications of the results for cultural refinements to our understanding of disgust propensity and BII phobia are discussed.  相似文献

In this experiment, 23 preschool children participated in two adult-child shared storybook reading sessions over a 1-week period. The objective was to characterize the influence of various conditions of word exposure upon children's receptive and expressive learning of novel words occurring within storybook reading interactions. Specifically, the effects of two contrasting conditions were examined: (a) adults' questioning versus labeling of novel words, and (b) adults' use of perceptual versus conceptual questions about novel words. Results suggested that adults' labeling of novel words facilitated children's receptive word learning more so than questioning; however, this effect was not observed for expressive word learning. Results also suggested no difference in receptive or expressive word learning as a result of conceptual versus perceptual questions. Implications of these findings are discussed.  相似文献

ABSTRACT

The example of the Spanish poet’s amnesia, mentioned by Spinoza in the scholium of proposition 39 of part IV of the Ethics in order to elucidate his conception of death, has given rise to many controversies in the scholarly interpretations, which in most cases maintain that the poet dies and that Spinoza himself thought this way. However, the matter is more complex than it at first appears and in this article I take a different path by reconstructing this scholium anew and providing an alternative interpretation. The comparison with selected passages of part V highlights the presence of a bi-conditional between the ratio of motion and rest that a body possesses, and its aptitude to be affected and affect in many more ways. In particular, the latter allows us to acknowledge the continuity of the poet’s individuality, expressed in his mind–body union grounded by the parallelism theory. As a result, the poet case has a crucial explanatory role for Spinoza’s theory of the eternity of the human mind and if one misunderstands the former, the latter is also misconceived.  相似文献
