Neural correlates of audiovisual integration of semantic category information

Previous studies have found a late frontal-central audiovisual interaction during the time period about 150-220 ms post-stimulus. However, it is unclear to which process is this audiovisual interaction related: to processing of acoustical features or to classification of stimuli? To investigate this question, event-related potentials were recorded during a words-categorization task with stimuli presented in the auditory-visual modality. In the experiment, congruency of the visual and auditory stimuli was manipulated. Results showed that within the window of about 180-210 ms post-stimulus more positive values were elicited by category-congruent audiovisual stimuli than category-incongruent audiovisual stimuli. This indicates that the late frontal-central audiovisual interaction is related to audiovisual integration of semantic category information.     

Mother–Father–Child Triadic Interaction and Mother–Child Dyadic Interaction: Gender Differences Within and Between Contexts

Differences in mother and father behavior during a triadic interaction session, and differences in mothers’ behavior across triadic and dyadic interaction, were examined in 60 two-parent families with an 11- to 15-month-old child (30 boys, 30 girls). Results revealed that mothers were less involved, less sensitive, and more negative during triadic than during dyadic interaction. Mothers of sons displayed more emotion during triadic interaction than mothers of daughters did. Mothers were more involved with children than fathers were during triadic interaction, whereas fathers displayed more emotion than mothers did during triadic interaction. Fathers were more supportive of mothers, and mothers were more intrusive toward fathers, during triadic interaction. The results are discussed in terms of the role that context plays in gender-typed patterns of family interaction.     

Interactions between mothers and infants: impact of maternal anxiety

The aim of the study was to examine the impact of anxiety in the postnatal year on maternal contribution to mother-infant interaction. Participants were 32 mothers with high anxiety and 32 mothers with low anxiety, when their infants were aged 10-14 months. Mother-infant interaction was videotaped during a standardized play situation and coded blind to group status. High trait anxiety mothers showed less sensitive responsivity (p<.05) and reduced emotional tone (p<.05) during interaction. When participants scoring high in depressive symptomatology were removed for a subgroup analysis, the same pattern of results was obtained, suggesting that the observed differences in mother-infant interaction were due to group differences in anxiety.     

The role of inhibitory control in children's cooperative behaviors during a structured puzzle task

This study examined the role of inhibitory control (measured by Stroop interference) in children’s cooperative behaviors during a structured puzzle task. The sample consisted of 250 8-, 10-, and 12-year-olds (117 girls and 133 boys) attending classrooms in three primary schools in Northern Italy. Children individually completed an elaborated Stroop task, were paired with classmates into 125 dyads, and were observed during a 10-min puzzle task. Results confirmed that interaction partners exhibited similar levels of cooperative behaviors, and the cooperative behaviors of children predicted changes in the cooperative behaviors of their partners throughout the puzzle task. Cooperative behaviors of each interaction partner were predicted by the child’s own inhibitory control as well as the inhibitory control of the partner. Findings are discussed within a developmental contextual framework.     

Infants of “depressed” mothers interact better with their nondepressed fathers

To determine whether infants of “depressed” mothers interact better with their nondepressed fathers, twenty-six 3- to 6-month-old infants were videotaped during face-to-face interactions with their parents. The “depressed” mother group consisted of twelve 3- to 6-month-old infants and their “depressed” mothers and nondepressed fathers. The control group was composed of 14 nondepressed mothers and nondepressed fathers and their 3- to 6-month-old infants. In the “depressed” mother group, the nondepressed fathers received better interaction ratings than the “depressed” mothers. In turn, the infants received better interaction ratings when they interacted with their nondepressed fathers than with their “depressed” mothers. In contrast, nondepressed fathers and mothers and their infants in the control group did not differ on any of their interaction ratings. These findings suggest that infants' difficult interaction behaviors noted during interactions with their “depressed” mothers may not extend to their nondepressed fathers. The data are discussed with respect to the notion that nondepressed fathers may “buffer” the effects of maternal depression on infant interaction behavior.     

American and Chinese parental involvement in young children's mathematics learning

This study compared the involvement of American and Chinese mothers in their 5- and 7-year-old children's number learning in their everyday experience and during mother–child interaction on mathematics tasks pertaining to proportional reasoning. Results indicated that Chinese mothers of both the 5- and 7-year-old children were more likely to teach mathematics calculation in their everyday involvement with children's number learning than their American counterparts. No differences were found in maternal instruction between American and Chinese mothers during the mother–child interaction on mathematics tasks. However, maternal instruction was related to Chinese children's learning of proportional reasoning but negligibly related to American children's learning of proportional reasoning.     

Dyadic parent-child interaction during early childhood: contributions of parental and child personality traits

Individual differences in personality play a major role for functioning in a multitude of important life domains, including one's interpersonal relationships. The present study examined the effects of parental personality and child temperament traits on dyadic parent-child interaction during early childhood. Participants were a community sample of 145 mothers, 145 fathers, and their 3- to 6-year-old children. Child traits were assessed using standardized laboratory paradigms, parents reported on their own traits, and parent-child interaction was assessed observationally. Parental positive emotionality, negative emotionality, and constraint subtraits were related to parental responsiveness; the number and type of parental bids and the quality of parental responsiveness were also a function of child positive emotionality and effortful control subtraits and, for mothers, child negative emotionality subtraits. Child traits were related to their own interaction behaviors; children higher on positive emotionality subtraits made more social bids, and children higher on effortful control subtraits made more influence attempts and fewer negative bids; child positive emotionality and effortful control subtraits were associated with higher quality child responsiveness. Findings speak to coherence in personality constructs across the life span, with comparable traits measured in adults and early childhood-aged children demonstrating remarkably consistent effects on dyadic interaction behavior.     

The Facilitation of Children's Social Interaction by a Picture-Cue Training Program

A social-interaction training procedure employing picture cues (photographs of play materials in their settings), prompts, and reinforcement was investigated to determine its effcct on subject-peer and subject-teacher interaction. The picture cues were designed to facilitate social interaction between three socially deficient language-delayed 4- to 6-year-old children and their respective classroom peers. One target child was deaf, one was unusually aggressive, and one was an elective mute. The picture-cue technique was designed to minimize reacher involvement: it allowed onc child to invite another to interact by displaying a picture of the interaction desired. Despite the children's differences, appropriate social interaction increased dramatically over each child's bascline rate during the Picture-Cue Conditions, required less tcacher time than traditionaI prompting procedures, and increased the functional aspect of naturally maintaining contingencies. This result may have been influenced by prompting procedures used in earlier conditions. The results indicate that picture cues facilitate communication and allow independent social interaction, and thus are functional and efficient mediating devices.     

The Application of the Temperament and Character Inventory (TCI) in Predicting General Social Adaptation and Specific Social Behaviors in a Dyadic Interaction

The goal of this study was to evaluate the ability of the harm avoidance (HA) and cooperativeness (C) dimensions of the Temperament and Character Inventory (TCI) to predict general social adaptation as measured by the Social Adaptation Self-Evaluation scale and specific social behaviors during a dyadic social interaction. A sample of 58 healthy volunteers participated in a social interaction with confederates. Social adaptation was negatively associated with HA scores (β= -.49), but positively associated with C scores (β= - .46). Eye-contact patterns were predicted by C scores based on general linear modeling (GLM) analysis. The results suggest that TCI should be included for the evaluation of treatment effects on social functioning.

The link between maternal interaction style and infant action understanding

The present study investigates whether the maternal interaction style is related to 6-month-old infants' action interpretation. We tested 6-month-olds ability to interpret an unfamiliar human action as goal-directed using a modified version of the paradigm used by Woodward, A. L. (1999). Infant's ability to distinguish between purposeful and non-purposeful behaviours. Infant Behavior & Development, 22, 145-160 and Király, I., Jovanovic, B., Prinz, W., Aschersleben, G., & Gergely, G. (2003). The early origins of goal attribution in infancy. Consciousness & Cognition, 12, 732-751. Additionally, all infants and their mothers participated in a free play situation to assess maternal interaction styles as measured by the CARE-Index. According to mothers' distinct interaction styles, infants were divided into three groups. Results suggest that at 6 months of age infants of mothers with a modestly controlling interaction style are better at interpreting a human action as goal-directed than infants of sensitive and relative unresponsive mothers. The ability to understand human action as goal-directed might be a corollary of an adaptive strategy in infancy.     

知情交互作用的实证研究现状与展望

知情交互作用(the interaction of cognition-emotion)是指认知与情绪之间相互作用,相互影响,二者密不可分.当前,知情交互作用的研究主要涉及两个方面:一是认知对情绪的影响,即认知对情绪的产生和情绪调节的影响;二是情绪对认知的影响,即情绪对感知觉、记忆和思维的影响.本文从实证角度,综合相关文献选取各自领域具有代表性的最新研究成果进行了概要述评,并进一步指出未来的研究应该在无意识情绪的脑机制、情绪-想象的交互作用、情绪-语言的交互作用,以及知-情-行的整合等方面进一步探讨.     

Interaction with Others Increases Decision Confidence but Not Decision Quality: Evidence against Information Collection Views of Interactive Decision Making

We present three studies of interactive decision making, where decision makers interact with others before making a final decision alone. Because the theories of lay observers and social psychologists emphasize the role of information collection in interaction, we developed a series of tests of information collection. Two studies with sports collection show that interaction does not increase decision accuracy or meta-knowledge (calibration or resolution). The simplest test of information collection is responsiveness - that people should respond to information against their position by modifying their choices or at least lowering their confidence. Studies using traditional scenarios from the group polarization literature show little responsiveness, and even "deviants," who interact with others who unanimously disagree with their choice, frequently fail to respond to the information they collect. The most consistent finding is that interaction increases people′s confidence in their decisions in both sports predictions and risky shift dilemmas. For predictions, confidence increases are not justified by increased accuracy. These results question theories of interaction which assume that people collect information during interaction (e.g., Persuasive Arguments Theory). They also question the labeling of previous results as "shifts" or "polarization." We suggest that interaction is better understood as rationale construction than as information collection - interaction forces people to explain their choices to others, and a variety of previous research in social psychology has shown that explanation generation leads to increased confidence. In Study 3, we provide a preliminary test of rationale construction by showing that people increase in confidence when they construct a case for their position individually, without interaction.     

Developing and maintaining social interaction in profoundly retarded young males

Social interaction was increased in five profoundly retarded males using formal training, stimulus control, and rewarded generalization procedures. Seven behaviors were monitored for each boy to determine whether correlated changes occurred in maladaptive behaviors as social interaction varied over the several phases of a withdrawal design that included multiple-baseline features. All five boys increased their social interaction and reduced unoccupied and self-stimulatory behavior. These changes were maintained as continuous reinforcement was reduced to a single response-contingent reinforcer per 15- minute session. Four follow-up probes showed the stability of the changes.This study was conducted with the excellent cooperation of the staff of Little Boys Ward and the Foster Grandparent Program at Colin Anderson Center, St. Mary's, West Virginia, and with the continued support of W. E. Richards, superintendent.     

The role of vocabulary ability during visual word recognition in younger and older adults

The role that vocabulary ability plays in adult age differences in word recognition was investigated. In Experiment 1, 44 older adults (ages 61-93 years) were compared with 44 younger adults (ages 18-39 years) on a standard lexical-decision task, with ambiguous words, unambiguous words, and pseudowords serving as stimuli. In Experiment 1, the Wechsler Adult Intelligence Scale-Revised (WAIS-R; D. Wechsler, 1981) vocabulary performance was uncontrolled across the younger and older adults, and the older adults had higher WAIS-R scores. There was no Group x Stimulus interaction. In Experiment 2, the data from the same 44 older adults were compared with data from a new sample of 44 younger adults (ages 18-44). Both groups were then matched on WAIS-R performance. Results revealed a significant Group x Stimulus interaction. Reaction time differences between the younger and older groups on the ambiguous words and unambiguous words were identical. The differences in reaction times for words and pseudowords were greater in the older adults. The importance of vocabulary ability during word recognition and lexical processing is discussed.     

Correlates of premarital relationships among unmarried youth in Pune district, Maharashtra, India

CONTEXT: Although premarital partnerships-whether or not they involve sex-are widely discouraged in India, some youth do form such partnerships. It is important to know more about the nature of and the factors associated with these relationships. METHODS: Data are drawn from a community-based study of 15-24-year-olds in urban slum and rural settings in Pune District, Maharashtra. Multivariate analyses were conducted to identify associations between youths' individual, peer and family factors and their experience of romantic relationships and physical intimacy, including intercourse. RESULTS: Among young men, 17-24% had had a romantic relationship, 20-26% had engaged in some form of physical intimacy and 16-18% had had sex; the proportions among young women were 5-8%, 4-6% and 1-2%, respectively. Exposure to alcohol, drugs or pornographic films and having more frequent interaction with peers were positively associated with romantic and sexual relationships for both young women and young men. Educational attainment was negatively associated with both types of relationships for young women, but only with sexual relationships for young men. Closeness to parents was negatively associated with relationships only for young women. Young women whose father beat their mother were more likely than other young women to form romantic partnerships, and those beaten by their family had an elevated risk of entering romantic and sexual partnerships. Youth who reported strict parental supervision were no less likely than others to enter relationships. CONCLUSIONS: Program interventions should ensure that youth are fully informed and equipped to make safe choices and negotiate wanted outcomes, while positively influencing their peer networks; encourage closer interaction between parents and children; and be tailored to the different circumstances and experiences of young women and men.     

Understanding the properties of interactive televised characters

Children's television programming frequently uses interactive characters that appear to directly engage the viewers. These characters encourage children to answer questions and perform actions to help the characters solve problems in the televised world. Children readily engage in these interactions; however, it is unclear why they do so. To investigate this issue, 53 5-, 7-, and 9-year-olds made decisions about events occurring in the real world based on information provided by a live individual and by a televised interactive computer-generated character. Five-year-olds followed the advice of both the live individual and the televised computer-generated character, whereas 7- and 9-year-olds only followed the advice of the live individual. Results are discussed in terms of a transition from children believing that interactive televised characters can engage in a real communicative interaction to children understanding that this apparent interaction is an illusion.     

A Population Study of Victimization, Relationships, and Well-Being in Middle Childhood

The paper presents a population-based study on the association of victimization and peer and adult relationships with children’s life satisfaction, self-esteem, anxiety, and depressive symptoms. The study extends previous research by examining 2-, 3-, and 4-way higher-order interaction effects (moderation hypotheses) of adults and peer relationships, victimization, and gender on positive and negative aspects of children’s well-being. The study draws from a representative population-level sample of 2,792 4th graders (M _age = 9.70 years; 48.2 % girls). Data were obtained via student self-report survey on the Middle Years Development Instrument (MDI). Given the nested data (children within classrooms), we employed multi-level regression analyses. Positive relationships with adults and peers were most strongly associated with life satisfaction and self-esteem, whereas victimization was most strongly associated with depressive symptoms and anxiety. No significant 2- or 3-way interactions were identified. The 4-way interaction of gender, adult connectedness, peer connectedness, and victimization was significant for three outcomes; that is, victimization was particularly strongly associated with low life satisfaction, low self-esteem, and high depressive symptoms for girls with low self-reports of peer and adult connectedness. The findings have implications for promoting children’s well-being in school and community contexts, corroborating interventions that foster relationship-building skills and simultaneously reduce victimization.
