Teaching and learning as a bi-directional activity: investigating dyadic interactions between child teachers and child learners

Building upon Vygotsky's ideas about the shift from other- to self-regulation in the “zone of proximal development,” we study how children, when teaching a board game that they previously co-constructed with a peer to a new child, reciprocally negotiate the roles of teacher and learner. From our investigation, we find that the quality of the relationship between teacher and learner changes from one reflecting guidance to one reflecting collaboration. This collaborative model of teaching and learning differs from more traditional models by which an active adult teacher is depicted as transmitting knowledge to a relatively passive child learner. Instead, we contend and demonstrate that the practice of teaching and learning is best viewed as a bi-directional interaction that results in the cognitive growth of both teacher and learner.     

Sensory modality and stimulus control in the pigeon: Cross-species generality of single-incentive selective-association effects

In earlier studies with rats, the effectiveness of the auditory element of a tone–light discriminative stimulus was enhanced when the conditioned incentive value of the compound was negative rather than positive. The present experiment systematically replicated these results in pigeons trained to press a treadle in the presence of a tone–light compound under food-reinforcement or shock-avoidance schedules. Positive incentive value was conditioned to the compound by associating it with either food or relative safety from shock. The compound was made negative in other groups by associating it with shock or the absence of food. When tone and light were presented separately following this training, control by the auditory element was significantly enhanced in the conditions designed to make the compound negative rather than positive. The similarity of this constraint on learning in rats and pigeons suggests that it involves a fundamental attentional and incentive-motivational process with widespread species generality.     

The buffering power of overt socially supportive and unsupportive behaviors from the significant other on posttraumatic stress disorder individuals’ emotional state

Background and objectives: Social support is one of the three strongest predictors of posttraumatic stress disorder (PTSD). In the present study, we aimed to assess the buffering power of overt socially supportive and unsupportive behaviors from the significant other, in a group with PTSD and a comparison group. Design and methods: A total of 46 individuals with PTSD and 42 individuals with obsessive-compulsive disorder (OCD) or panic disorder (PD) completed diagnostic interviews and an anxiety-oriented social interaction with a significant other. Heart rate of participants was continuously measured during this interaction and overt social behaviors from the significant other were recorded on videotape and coded using a validated system. Results: Changes in heart rate in PTSD participants correlated negatively with changes in overt socially supportive behaviors from their significant other (r from ?.36 to ?.50, p?<?.05), while changes in overt unsupportive social behaviors from their significant other did not yield any significant correlation (r from ?.01 to .05, p?>?.05). No such statistically significant association emerged in the group with OCD or PD (r from .01 to ?.27, p?>?.05). Conclusions: This study sustain the buffering power of overt supportive behaviors from the significant other on heart rate changes in PTSD.     

Parental Guidance and Children's Executive Function: Working Memory and Planning as Moderators During Joint Problem‐Solving

Cognitive aspects of children's executive function (EF) were examined as moderators of the effectiveness of parental guidance on children's learning. Thirty‐two 5‐year‐old children and their parents were observed during joint problem‐solving. Forms of guidance geared towards cognitive assistance were coded as directive or elaborative, and children's responses were recorded. Children were then assessed on an independent version of the same task. A parent‐rated composite of working memory and planning was used as a measure of EF. Directive guidance by parents was associated with more child errors during the joint activity, whereas elaborative guidance was associated with better performance. Parent‐rated EF moderated the relation, such that the relation between elaborative guidance and better performance was only significant for children with low EF. During the independent task, EF again moderated the relation between parent guidance and children's performance, such that children with low EF did worse when parents had provided more directive guidance; for children with high EF, directive guidance was associated with better independent performance. These findings suggest that the extent to which children's performance relates to different forms of parents' guidance varies, and elaborative assistance may be more helpful for children with low EF.

Emotion Regulation in At‐Risk Preschoolers: Longitudinal Associations and Influences of Maternal Histories of Risk

Emotion regulation is a key challenge of early childhood. The present study examined emotion regulation behaviour longitudinally from infancy to preschool. The continuity of emotion regulation was explored within the larger ecological context of maternal childhood histories of aggression and social withdrawal and maternal use of constructive and non‐constructive behaviours. Forty‐five mothers with childhood histories of aggression or social withdrawal from the Concordia Longitudinal Risk Project, a prospective, longitudinal, intergenerational study, participated with their preschool children. Infants' emotion regulation behaviour was observed during interactions with their mothers when they were 5½ months of age. Emotion regulation in these same children as preschoolers was coded during an interference task using the Preschooler Self‐Regulatory Scheme. Longitudinal findings demonstrated continuity in children's use of emotion regulation behaviours from infancy to preschool. Higher maternal childhood histories of risk, specifically social withdrawal, contributed to the prediction of preschoolers' increased attention‐seeking behaviours. Mothers' use of non‐constructive verbalizations predicted more maladaptive styles of emotion regulation in their preschoolers. The findings highlight the importance of helping children develop adaptive emotion regulation skills from a young age and have implications for the design of preventive intervention programmes to help parents foster children's emotion regulation abilities.

Does It Help or Hinder? Technology and Its Role in Healing Post Affair

For couples experiencing infidelity, technology can be either a source of comfort or a constant threat. Technology has created an atmosphere where individuals have access to more people, in more ways, and at more times than ever before. While this accessibility has increased partners' ability to connect with each other, it has also increased opportunities for infidelity and makes it easier to maintain an affair. From an attachment perspective, infidelity can lead to heightened sensitivities that alter how an individual experiences the availability, responsiveness, and engagement of their partner. Everyday interactions like text messages, phone calls, and computer use become potential threats that compromise the safety of the relationship. Using an extensive clinical vignette, this article highlights the systemic relationship between technology, attachment, and infidelity and provides clinicians with a framework to use when helping couples heal post affair.     

母亲-胎儿关系：概念、测量和影响因素

亲子关系并不仅仅始于出生之后,在怀孕期间孕妇就开始建立与胎儿的关系。母亲-胎儿关系是孕妇在怀孕期间对胎儿所产生的一种对胎儿的认知表征、投入的情感以及与胎儿的互动的关系,具有重要的理论与实践意义。目前用于测量母亲-胎儿关系水平的主要工具为母亲-胎儿依恋量表,母亲孕期依恋量表以及胚胎依恋量表。多种因素会对母亲-胎儿关系产生影响,主要包括孕妇年龄、文化等人口学因素,孕周、孕期检查等怀孕相关因素,以及人格特点、心理健康、社会支持等心理社会因素。未来研究要对研究方法进行整合、更多关注父亲-胎儿关系的发展特点,并尝试探索干预措施来提高这种亲子关系的质量。     

Social regulation of human gene expression

ABSTRACT— The relationship between genes and social behavior has historically been construed as a one-way street, with genes in control. Recent analyses have challenged this view, by discovering broad alterations in the expression of human genes as a function of differing socio-environmental conditions. The emerging field of social genomics has begun to identity the types of genes subject to social regulation, the biological signaling pathways mediating those effects, and the genetic polymorphisms that moderate socioenvironmental influences on human gene expression.
