The More the Merrier? Sibling Composition and Early Manifestations of Theory of Mind in Toddlers

Sibling relationships are argued to offer a rich social context for the development of young children’s theory of mind (ToM). There is evidence that the presence of siblings, particularly older siblings, may promote preschoolers’ ToM, but it has not been investigated among toddlers. This study evaluated differences in early manifestations of ToM between toddlers in different sibling compositions: 1) without a sibling, 2) with younger siblings only, and 3) with older siblings only. The sample included 227 toddlers who completed 2 tasks assessing their understanding of discrepant desires and visual perspectives. Results indicated that only children and those who had older siblings did not differ from each other on either task. However, on both tasks, toddlers with younger siblings performed significantly more poorly compared with those with older siblings. Moreover, children with younger siblings demonstrated poorer visual-perspective understanding compared with only children. It may be critical to take siblings’ birth order into account when investigating their respective effects on each other’s ToM, especially in toddlerhood.     

A threshold approach to understanding the origins of attachment disorganization

Disorganized attachment in infancy is known to predict a wide range of maladaptive outcomes, but its origins are poorly understood. Parental lack of resolution concerning loss or trauma has been proposed to result in atypical parenting behaviors, which in turn have a disorganizing effect on the parent-child relationship. The authors review the evidence for this transmission pathway, considering other factors (e.g., social environment, child characteristics) that might enrich understanding of the antecedents of disorganization. A threshold approach is proposed to explain (a) why different parental behaviors are linked to disorganization depending on prevailing social conditions and (b) why certain children appear more vulnerable to forming a disorganized attachment relationship.     

Asian cultural values gap, cognitive flexibility, coping strategies, and parent-child conflicts among Korean Americans

The study examined Korean American college students' perceived Asian cultural values gap between themselves and their parents, cognitive flexibility, and coping strategies. The relationships between these factors were studied with the intensities and types of parent-child conflicts. The results indicated that the participants adhered less strongly to Asian values than their parents. When faced with conflicts, the participants reported using problem solving coping strategy to the greatest extent, followed by social support coping strategy, and then avoidance coping strategy. Simultaneous regression analyses revealed a positive relationship between the participant-perceived parent-child values gap and the intensity of conflicts, particularly in the area of dating and marriage. There were inverse relationships between cognitive flexibility and the intensity of conflicts, specifically in the area of dating and marriage. A positive relationship was observed between the use of social support coping strategy and intensity of conflicts. Hierarchical regression analyses revealed a significant interaction effect in which participant-perceived parent-child values gap and cognitive flexibility were related to increased frequency of dating and marriage conflicts.     

Understanding Information Selection and Encoding from a Dynamic,Energy Saving,Evolved, Embodied,Embedded Perspective

This article uses the Dynamic Human Centric Communication Systems Theory to reconceptualize 4 selected attributes of attention from a human‐centric point of view. Information is defined with respect to its relationship in the environment to the human in terms of time and space. The 4 attributes considered are stability, imminence, motivational relevance, and task relevance. An experiment was conducted in which encoding was assessed using a signal detection analysis of a change detection task. Results supported the prediction that story and motivational relevance would have opposite effects on the encoding of stable information as a function of imminence. Differences in memory predictions made by traditional theoretical approaches and the DHCCST are discussed in light of the results of the experiment.     

Learnability of Pregroup Grammars

This paper investigates the learnability by positive examples in the sense of Gold of Pregroup Grammars. In a first part, Pregroup Grammars are presented and a new parsing strategy is proposed. Then, theoretical learnability and non-learnability results for subclasses of Pregroup Grammars are proved. In the last two parts, we focus on learning Pregroup Grammars from a special kind of input called feature-tagged examples. A learning algorithm based on the parsing strategy presented in the first part is given. Its validity is proved and its properties are examplified.     

Maximizing the efficacy of interoceptive exposure by optimizing inhibitory learning: A randomized controlled trial

Cognitive-behavioral treatments for panic disorder (PD) emphasize interoceptive exposure (IE) to target anxiety sensitivity (AS) but vary considerably in its manner of delivery. This randomized controlled trial was conducted to compare the efficacy of the low-dose delivery of IE exercises often prescribed in treatment protocols to an intensive form of IE hypothesized to optimize inhibitory learning. Participants (N = 120) with elevated AS were randomly assigned to one of four single-session interventions: (a) low-dose IE as prescribed in Barlow and Craske's Panic Control Treatment, (b) low-dose IE without controlled breathing or a lengthy between-trial rest period, (c) intensive IE, or (d) expressive writing control. Compared to the other conditions, intensive IE produced significantly greater reductions in AS and fearful responding to a straw breathing task from pretreatment to posttreatment. Maintenance of gains during the follow-up period did not differ between conditions. Changes in fear toleration and negative outcome expectancies fully mediated the superior efficacy of intensive IE over low-dose IE. The two low intensity IE conditions produced particularly high rates of fear sensitization on between-trial and outcome variables. The findings suggest that the intensive delivery of IE exercises has the potential to improve the efficacy of exposure-based treatments for PD.
