For effective prelinguistic communication, infants must be able to direct their attention, vocalizations, and nonverbal gestures in social interactions. The purpose of our study was to examine how different styles of caregiver responses influenced infant attentional and communicative behavior in social interactions, based on prior studies that have shown influences of responsiveness on attention, language and cognitive outcomes. Infants were exposed to redirective and sensitive behavior systematically using an ABA design to examine real-time changes in infants’ behavior as a function of caregiver responses. During the two baseline “A” periods, caregivers were instructed to play as they would at home. During the social response “B” period, caregivers were instructed to respond sensitively to infants’ behavior on one visit and redirectively on the other visit. Results demonstrated that when caregivers behaved redirectively, infants shifted their attention more frequently and decreased the duration of their visual attention. Caregiver responses also resulted in changes in vocal and gesture production. Infants decreased their production of caregiver-directed vocalizations, gestures, and gesture-vocal combinations during in the redirective condition. Results suggest that caregiver sensitive responding to infants’ attentional focus may be one influence on infants’ attentional and prelinguistic communicative behavior.  相似文献

Growing evidence suggests that visual information is processed differently in the near-hand space, relative to the space far from the hands. To account for the existing literature, we recently proposed that the costs and benefits of hand proximity may be due to differential contributions of the action-oriented magnocellular (M) and the perception-oriented parvocellular (P) pathways. Evidence suggests that, relative to the space far from the hands, in near-hand space the contribution of the M pathway increases while the contribution of the P pathway decreases. The present study tested an important consequence of this account for visual representation. Given the P pathway’s role in feeding regions in which visual representations of unified objects (with bound features) are formed, we predicted that hand proximity would reduce feature binding. Consistent with this prediction, two experiments revealed signs of reduced feature binding in the near-hand space, relative to the far-hand space. We propose that the higher contribution of the M pathway, along with the reduced contribution of the P pathway, shifts visual perception away from an object-based perceptual mode toward a feature-based mode. These results are discussed in light of the distinction between action-oriented and perception-oriented vision.  相似文献

Despite evidence for its health‐related benefits, little is known on the psychological predictors of the participation in leisure activities across the lifespan. Therefore, this study aimed to identify whether personality is associated with a variety of different types of activities, involving physical, cognitive, and social components. The samples included individuals from the second wave of the National Study of Midlife in the United States (N = 3,396) and community‐dwelling French individuals (N = 2,917) aged between 30 and 84. Both samples completed measures of the five‐factor model of personality. To create an activity index, we combined the physical, social, and cognitive (games and developmental) activities performed at least once a month. In both samples, individuals who scored higher on extraversion and openness were more likely to engage in a variety of activity types. The findings were consistent across two samples from different western societies and suggest that extraversion and openness contribute to social, cognitive, and physical functioning across the lifespan.  相似文献

Cognitive interference theories (e.g. attentional control theory, processing efficiency theory) suggest that high levels of trait anxiety predict adverse effects on the performance of cognitive tasks, particularly those that make high demands on cognitive resources. We tested an interaction hypothesis to determine whether a combination of high anxiety and low working memory capacity (WMC) would predict variance in demanding cognitive test scores. Ninety six adolescents (12‐ to 14‐years‐old) participated in the study, which measured self‐report levels of trait anxiety, working memory, and cognitive test performance. As hypothesized, we found that the anxiety‐WMC interaction explained a significant amount of variance in cognitive test performance (ΔR2 .07, < .01). Trait anxiety was unrelated to cognitive test performance for those adolescents with average WMC scores (β = .13, > .10). In contrast, trait anxiety was negatively related to test performance in adolescents with low WMC (β = ?.35, < .05) and positively related to test performance in those with high WMC (β = .49, < .01). The results of this study suggest that WMC moderates the relationship between anxiety and cognitive test performance and may be a determinant factor in explaining some discrepancies found in the literature. Further research is needed to fully understand the mechanisms involved.  相似文献

Although religion is an important influence on a variety of social attitudes, the relationship between religion and views on family planning remains underexplored, especially in terms of attitudes relating to public policy. Using data from a nationally-representative survey (N = 1,500) fielded in 1998, we examine the influence of religious affiliation, subcultural identification, and attendance on three aspects of attitudes toward contraception in the public sphere. Specifically, we explore opinions regarding the public consequences of contraception and the responsibility for making contraception available as part of health care services in the United States. More frequent religious attendance is linked to less-approving opinions about contraception and less support for its provision by the US government and health insurers. Catholic affiliation is not consistently associated with the examined opinions, and we find mixed results for conservative Protestants. Including religious subcultural identities yields additional information, with born-again Christians reporting less positive opinions about the consequences of contraceptive availability, while evangelical identity is linked to negative views on policy aimed at increasing access to family planning services. These findings contribute to knowledge about the relationship between religion and attitudes toward policy-relevant aspects of contraception, as well as the broader social influences of religious subcultural identification.  相似文献

Sensitivity to the extra-linguistic context, as exhibited by indexical and demonstrative expressions, and sensitivity to the linguistic context, as exhibited by, for example, anaphoric uses of third person pronouns, are regularly regarded as different and independent phenomena. The data on indexicals, demonstratives, and third person pronouns, however, call for a more unified notion of context and of context sensitivity. This paper aims to develop such a unified picture by generalizing the notion of anaphora to encompass extra-linguistic context dependency and generalizing the notion of a structured discourse context so that contexts contain antecedents for expressions that refer to entities in the extra-linguistic context.  相似文献

This study examines the links between employee perceptions of job insecurity, the work–nonwork interface, and stress‐related outcomes. Drawing on an adaptation perspective, we expect employees feeling greater job insecurity to engage in adaptive work behaviors including less use of work–nonwork support programs and greater willingness to let work permeate into one's personal life, which in turn will associate with greater work–nonwork conflict and emotional exhaustion. Data were collected from employees within a large energy company at 2 points in time. Results support the model, offering important insights into employee behavioral responses to job insecurity and key mechanisms through which insecurity may foster diminished employee well‐being.  相似文献

This study examined impairment in multiple domains of functioning in children with and without ADHD who present with high or low levels of sluggish cognitive tempo (SCT) while taking into account the total symptom ratings of ADHD. Participants were 584 children in kindergarten through eighth grade (55.7 % male, 91.7 % Caucasian), drawn from five archival datasets. Two, 2 (SCT groups: high and low) x 3 (ADHD Status: ADHD-I, ADHD-C, and non-ADHD) MANCOVAs were conducted with the total ADHD symptom ratings and child age as covariates. One MANCOVA was conducted on scores on the teacher Impairment Rating Scale (IRS; Fabiano et al. Journal of Clinical Child and Adolescent Psychology 35:369–385, 2006) and the other on the 6 scores on the parent IRS. The results indicated that the presence of SCT symptoms was associated with greater functional impairment at home according to parent report while it was associated with less functional impairment at school according to teacher report. Thus, the relationship between SCT symptoms and impairment differs depending on the informant and the context in which impairment is evaluated.  相似文献

One of the two stated objectives of the new “Research Note” section of Political Psychology is to present short reports that highlight novel methodological approaches. Toward that end, we call readers' attention to the “flanker task,” a research protocol widely employed in the study of the cognitive processes involved with detection, recognition, and distraction. The flanker task has increasingly been modified to study social traits, and we believe it has untapped value in the area of political psychology. Here we describe the flanker task—discussing its potential for political psychology—and illustrate this potential by presenting results from a study correlating political ideology to flanker effects.  相似文献

The purpose of the study was to examine students’ motivational profile at the beginning of a College program and to test whether these profiles were associated with students’ achievement through their relations with behaviors adopted during the semester. A prospective design with two time points of data collection was conducted in first-year students enrolled in a French University. Motivations were assessed at the beginning of the semester (510 participants at Time 1), and study strategies and temporal resources devoted to academics at the end of it (301 participants at Time 2). Administrative records were used to check for persistence in the program and to assess achievement. Cluster analyses revealed five distinct profiles: additive; self-determined; moderate; low; non self-determined. Furthermore, motivational profile was linked to final grade through the partial mediation of the percentage of classes attended. As a whole, students with a self-determined profile demonstrated the best academic adjustment, whereas those with a low or non self-determined profile displayed the poorest outcomes.  相似文献
