While viewing faces, human adults often demonstrate a natural gaze bias towards the left visual field, that is, the right
side of the viewee’s face is often inspected first and for longer periods. Using a preferential looking paradigm, we demonstrate
that this bias is neither uniquely human nor limited to primates, and provide evidence to help elucidate its biological function
within a broader social cognitive framework. We observed that 6-month-old infants showed a wider tendency for left gaze preference
towards objects and faces of different species and orientation, while in adults the bias appears only towards upright human
faces. Rhesus monkeys showed a left gaze bias towards upright human and monkey faces, but not towards inverted faces. Domestic
dogs, however, only demonstrated a left gaze bias towards human faces, but not towards monkey or dog faces, nor to inanimate
object images. Our findings suggest that face- and species-sensitive gaze asymmetry is more widespread in the animal kingdom
than previously recognised, is not constrained by attentional or scanning bias, and could be shaped by experience to develop
adaptive behavioural significance. 相似文献

This study examined parent-child interactions and parent characteristics in families of nonproblem children and attention deficit hyperactivity disorder (ADHD) children with lower (ADHD-LOD) and higher (ADHD-HOD) levels of oppositional-defiant behavior. Families of ADHD children were recruited from a parent training program. Observed and parent-reported child behavior problems were highest in the ADHD-HOD group. Observed parent behavior revealed few differences, but daily reports indicated that parents in both ADHD groups used more negative-reactive and fewer positive parenting strategies than control parents. Maternal psychological functioning differed between the ADHD and nonproblem groups, but not between the two ADHD groups. Fathers of ADHD-HOD children reported more psychological disturbance than controls. Parenting self-esteem was lowest in the ADHD-HOD group and highest in the nonproblem group. The results support the LOD and HOD distinction, but also suggest that, although certain difficulties are more common in the families of ADHD-HOD children, families of ADHD-LOD children also differ from controls on a number of dimensions.This research was supported by grants from the Medical Research Council of Canada and the British Columbia Health Research Foundation. Appreciation is extended to Josie Geller, Kim Behrenz, Susan Greaves, and Sonia Pietzsch who assisted with data collection and coding, and to the families who generously gave their time to participate in the research. Thanks also to two anonymous reviewers for their comments. 相似文献

The potential for communication through the kinesthetic aspect of the tactual sense was examined in a series of experiments employing Morse code signals. Experienced and inexperienced Morse code operators were trained to identify Morse code signals that were delivered as sequences of motional stimulation through up-down displacements (roughly 10 mm) of the fingertip. Performance on this task was compared with that obtained for both vibrotactile and acoustic presentation of Morse code using a 200-Hz tone delivered either to the fingertip through a minishaker or diotically to the two ears under headphones. For all three modalities, the ability to receive Morse code was examined as a function of presentation rate for tasks including identification of single letters, random three-letter sequences, common words, and sentences. Equivalent word-rate measures (i.e., product of percent correct scores and stimulus presentation rate) were nearly twice as high for auditory presentation as for vibrotactile stimulation, which in turn was about 1.3 times that for motional stimulation. The experienced subjects outperformed the inexperienced subjects by amounts that increased with task complexity. For example, the former were able to receive sentences at 18 words/min with motional stimulation, whereas the latter, following 75 h of training, were unable to perform this task. The present results and those of other research with tactual communication systems are compared, particularly regarding estimates of information-transfer rates. 相似文献

Relationships among maternal characteristics, ratings of child behavior, and observed mother-child interactions were examined in a sample of 40 4- to 12-year-old children with externalizing disorders. Mothers and children were observed in a task interaction and mothers provided self-reports of depressed mood, parenting self-esteem, marital satisfaction, social support, and life stress. Child behavior was rated by both mothers and teachers. Several significant correlations were found among observed mother and child behaviors and among maternal self-report measures. However, few significant relationships were found between maternal characteristics and observed mother or child behavior. Although life stress predicted increased child negativity, maternal depressed mood was related to more appropriate child behavior. Mother and teacher ratings of child behavior demonstrated few significant relationships with other measures. These results suggest that, in samples comprised primarily of children with attention deficit disorder from socially advantaged families, few relationships exist between maternal characteristics, parenting behavior, and child behavior.This study was part of a doctoral dissertation conducted by the first author at Florida State University, under the direction of the second author, and supported by the Social Sciences and Humanities Research Council of Canada. Portions of the data also appear in a chapter by Johnston titled A behavioral-family systems approach to assessment: Maternal characteristics associated with externalizing behavior in children. In R. Prinz (Ed.),Behavioral assessment of children and families (Vol. 4, pp. 163–189). Greenwich, CT: JAI Press. The authors express appreciation to Alan Lang, Barbara Licht, and Richard Tate, for their thoughtful comments. We are grateful to Beverley Atkeson and a dedicated group of coders and to Dr. C. E. Cunningham and the staff of the Chedoke Child and Family Center for their support. Finally, our thanks to the families who participated. 相似文献

This study was designed to test the hypothesis that systematic variations in listener behavior can have an important influence on both speaker behavior and communicative success among children. In particular, we investigated the idea that systematic variations in listener behavior might have not only within-trial effects on the adequacy of speakers' messages and the accuracy of communication among children, but also cumulative effects on speakers' initial messages across trials. Effects of stimulus complexity were also examined. Pairs of 7- and 9-year-old children participated in a referential communication game, with the younger child serving as speaker and the older one as listener. Half of the listeners were given a plan for effective listening which emphasized the importance of asking questions if the speakers' messages were ambiguous. Replicating earlier findings, the plan manipulation was successful in encouraging listeners to ask questions when necessary. The major result was that listener questions not only had the expected trial-by-trial effect on message adequacy and communicative accuracy, but also showed a cumulative effect on speaker performance. When exposed to systematic listener feedback, speakers improved their initial messages over trials. Stimulus complexity was not a major determinant of performances. These findings suggest that provision of systematic listener feedback may be an effective method for teaching speaker skills to young children. 相似文献

The present study suggests a method with which to assess the interrelations between different types of pretend play. In contrast to standard methods in this area, the various types of pretend play were measured within an interactive play scenario. The pretend play tasks were included in a semi‐structured play sequence and presented to young children between 24 and 30 months of age (N=30). Self‐ and doll‐directed pretence, object substitution, pretence with realistic objects, and self‐initiated pretend play, as well as the understanding that an object had been given two identities was tested. The capacity for dual representation was assessed by asking for the real and pretend identity of an object. Age differences were found in the overall score for elicited pretence but not for all items separately. Individual items also differed in difficulty and thus are of potential use for assessing intraindividual differences in pretend play. Findings are discussed in the context of current theories and methods concerning the development and assessment of pretend play. 相似文献

Research suggests that an overgeneral autobiographical memory style (i.e., retrieval of general memories when instructed to retrieve a specific episodic memory) represents a vulnerability marker for depression. Although adolescence is a period of high risk for the emergence of depression, little research has investigated the associations among overgeneral memory, psychopathology, and risk factors longitudinally in a community sample in this age group. We, therefore, investigated overgeneral memory, psychopathology (depression and anxiety), and rumination (an established risk factor for psychopathology) longitudinally in 269 typically-developing youth (125 females, 144 males) across 3 annual assessment points. We sought to determine whether 1) overgeneral memory would predict psychopathology across the entire sample, and 2) whether associations would vary as a function of longitudinal rumination growth. Across the entire sample, overgeneral memory did not predict psychopathology. For youth who reported elevated, and increasing, patterns of rumination over time, transient relationships between overgeneral memory and subsequent increases in anxiety were found. We conclude that overgeneral memory may represent a vulnerability marker for adverse psychological outcomes only for youth at risk for psychopathology. 相似文献
