用户运动信息反馈形式对体感操作用户体验的影响——一项基于Kinect的可用性研究

体感交互是新兴的人机交互方式;当前,相关的人因学研究相对缺乏。本研究采用典型任务结合主观评价法,首次探索了用户运动信息反馈形式对体感交互用户体验的影响。笔者从易学性、控制性、情感与心理负荷四个方面,比较了有、无人形反馈形式对游戏体感菜单操作可用性的影响。结果发现,二者在心理负荷上无差异,无人形反馈在易学性上优于有人形,但有人形反馈在控制感上优于无人形,且更受用户喜爱。基于该结果,笔者建议在体感操作界面上使用有人形反馈。     

Relationship of Attachment Style to Personality Factors and Family Interaction Patterns

This study investigated the relationships among attachment, personality style, and family interaction patterns. The results revealed that avoidant attachment style was associated with indirect affect expression as measured by somatic complaints, social isolation, family disengagement, and family conflict avoidance. Anxious/ambivalent style was associated with more overt expression of depression and anxiety. Family factors were not significantly related to either the anxious/ambivalent or secure styles. The implications and potential therapy benefits for use of attachment theory in family therapy and directions for future research are also addressed.

A prelinguistic gestural universal of human communication

Several cognitive accounts of human communication argue for a language-independent, prelinguistic basis of human communication and language. The current study provides evidence for the universality of a prelinguistic gestural basis for human communication. We used a standardized, semi-natural elicitation procedure in seven very different cultures around the world to test for the existence of preverbal pointing in infants and their caregivers. Results were that by 10-14 months of age, infants and their caregivers pointed in all cultures in the same basic situation with similar frequencies and the same proto-typical morphology of the extended index finger. Infants' pointing was best predicted by age and caregiver pointing, but not by cultural group. Further analyses revealed a strong relation between the temporal unfolding of caregivers' and infants' pointing events, uncovering a structure of early prelinguistic gestural conversation. Findings support the existence of a gestural, language-independent universal of human communication that forms a culturally shared, prelinguistic basis for diversified linguistic communication.     

Intergenerational Transmission of Risks for Problem Behavior

The intergenerational transmission of risk factors for problem behaviors was examined across three generations. Two hundred fifty-four 2-year-old toddlers, one or two of their parents, and one grandmother of each toddler were studied. Grandmothers and parents were individually interviewed. Data were analyzed for the male and female toddlers combined. Correlations and hierarchical multiple regression analyses were performed. Findings indicate that the grandmother–parent relationship, parental personality attributes, marital harmony, and drug use and the parent–toddler relationship, predict the toddlers' behavior. The investigation provides evidence for a longitudinal, intergenerational process whereby the grandmother–parent relationship and the parents' personality and behavioral attributes are transmitted across generations through their association with the parent–child relationship.     

Identifying the nature of impairments in executive functioning and working memory of children with severe difficulties in arithmetic

An age-matched achievement-matched design was used to examine whether the executive functioning and working memory impairments exhibited by children with severe difficulties in arithmetic (SDA) are better viewed as developmental lags or as cognitive deficits. Three groups of children were included: 20 SDA children, 20 typically achieving children (CM) matched in chronological age with the SDA children, and 20 younger typically achieving children (AM) matched in achievement with the SDA group. While children with SDA did not exhibit impairments in color-word inhibition and verbal working memory, they did demonstrate impairments in shifting, quantity-digits inhibition, and visuospatial working memory. As children with SDA did not perform more poorly than their AM counterparts on any of these tasks, impairments in specific areas of executive functioning and working memory appear to reflect developmental lags rather than cognitive deficits.     

Interaction between mother and pre-term infant at 34 weeks post-conceptional age

The impact of premature birth and perinatal medical status on early mother–infant interaction was assessed in 75 dyads with pre-term infants divided into three groups. Infants' gestational age at birth and need for neonatal intensive care intervention differentiated the groups: group 1, 23–31 weeks with intensive care; group 2, 32–35 weeks with intensive care; group 3, 32–35 weeks with no intensive care. The methodological approach was based on observations of the dyads performed when the infant reached a post. conceptional age of 34 weeks (4 weeks before estimated due date of delivery). The observations were conducted in the neonatal nursery during cleaning, face-to-face and feeding interactions. Significant group differences were found in infant distress, maternal sensitivity to the infant and dyadic behaviours of positive interaction. Group 1 dyads showed higher scores or more desirable performance than dyads of group 3. Group 2 dyads usually achieved intermediate scores and performed better than dyads of group 3, especially during the feeding situation. We suggest that, in addition to a possible emergence of maternal compensatory mechanisms in the higher-risk groups, the amount of dyadic experience after birth affects the quality of mother–infant interaction at this early stage.     

Reinforcement of probe responses and acquisition of stimulus control in fading procedures

Stimulus control of pigeons' key pecking was transferred from colors to lines by the method of stimulus fading. Fading was conducted with the addition of probes consisting of the line stimuli presented alone at each fading level. Probe responding was used to measure stimulus-control acquisition by the lines. Effects of reinforcement and nonreinforcement of probe responding upon acquisition of stimulus control were assessed using a single-organism repeated-acquisition design in which three fades were conducted serially. Probe responding was not reinforced in the first and third fade but was in the second. Reinforcement of probe responding substantially reduced the number of fading levels needed to complete fading. The outcome of a control experiment ruled out the possibility of accounting for these results in terms of the specific stimuli used in each fade or in terms of the sequential exposure to the three discriminations. Although probes permitted measurement of stimulus-control acquisition in fading, a measurement/acquisition interaction was also present.     

The Role of Parenting Programmes in the Prevention of Child Maltreatment

Child maltreatment is a major worldwide concern and continuing high rates of abuse demand action. This article examines the role of parenting programmes as a strategy to prevent child maltreatment in the population as a whole and also as a targeted intervention for parents who have abused, or are at risk of abusing, their children. We argue that a blend of universal and targeted interventions is needed to reduce the prevalence of child maltreatment. Parenting interventions that concurrently target positive parenting and effective child management skills, dysfunctional parental attributions, and increasing parents' capacity to regulate their emotions are particularly useful. A variant of the Triple P—Positive Parenting Program, known as Pathways Triple P, is discussed to illustrate the value of this approach. Contextual factors that need to be addressed in working with child protection cases are also discussed. The role of training and supervision is discussed in the context of disseminating evidence‐based parenting programmes, and future directions for research are presented.     

Neonatal imitation, gaze aversion, and mother-infant interaction

A relationship between elicited imitation in neonates and social interaction has been proposed by several investigators. The present work examines if such a relationship can be found when studying neonatal imitation, gaze aversion, and mother-infant interaction. Thirty-two infants were observed at 2 to 3 days, 3 weeks, and 3 months of age. Imitation of tongue protrusion and mouth opening was assessed in all three observations. In addition, a face-to-face interaction between mother and child was included when the child reached 3 months of age. The most striking result was a negative relationship between the infants' brief gaze aversion observed at 3 months of age while interacting with their mothers and the infants' imitative reactions at 2 to 3 days, 3 weeks, and 3 months of age. Behaviorally, these patterns indicate that high-imitating infants tend to display fewer episodes of brief gaze aversion when interacting with their mothers.     

祖辈共同养育背景下多重依恋关系及对幼儿社会-情绪性发展的影响

采用依恋Q-Set分类程序考察72名幼儿(M=17.51个月)的母子依恋和祖孙依恋的安全性,用《婴幼儿社会-情绪性评价量表》(ITSEA)同时评估了幼儿的社会-情绪性(包括外显行为域、内隐行为域、失调域和能力域)的发展状况。结果发现:(1)在祖辈参与共同养育的背景下,大多数幼儿可以形成安全型的母子依恋和祖孙依恋,母子依恋的安全性高于祖孙依恋;(2)母子依恋和祖孙依恋存在着中等强度的相关,36%幼儿的母子依恋和祖孙依恋的安全性水平不一致;(3)回归分析表明,与祖孙依恋的安全性相比,母子依恋的安全性对幼儿的社会-情绪性发展的各领域具有更大的相对预测力,支持主导性假说;(4)拥有高安全性母子依恋和祖孙依恋的幼儿,其外显行为域和内隐行为域的得分显著低于其他3组,高安全性母子依恋或祖孙依恋不能补偿对方的低安全性依恋的消极影响。在失调域上,母子依恋和祖孙依恋的安全性存在着交互效应。
