The nature of individual differences in working memory capacity: active maintenance in primary memory and controlled search from secondary memory

Studies examining individual differences in working memory capacity have suggested that individuals with low working memory capacities demonstrate impaired performance on a variety of attention and memory tasks compared with individuals with high working memory capacities. This working memory limitation can be conceived of as arising from 2 components: a dynamic attention component (primary memory) and a probabilistic cue-dependent search component (secondary memory). This framework is used to examine previous individual differences studies of working memory capacity, and new evidence is examined on the basis of predictions of the framework to performance on immediate free recall. It is suggested that individual differences in working memory capacity are partially due to the ability to maintain information accessible in primary memory and the ability to search for information from secondary memory.     

Construct validity of the helplessness/hopelessness/haplessness scale: correlations with perfectionism and depression

In a sample of 117 undergraduates, helplessness scores and the discrepancy scores on a measure of perfectionism predicted depression scores, providing evidence for construct validity for the hopelessness, helplessness, and haplessness scales.     

Generating Relations Elicits a Relational Mindset in Children

Relational reasoning is a hallmark of human higher cognition and creativity, yet it is notoriously difficult to encourage in abstract tasks, even in adults. Generally, young children initially focus more on objects, but with age become more focused on relations. While prerequisite knowledge and cognitive resource maturation partially explains this pattern, here we propose a new facet important for children's relational reasoning development: a general orientation to relational information, or a relational mindset. We demonstrate that a relational mindset can be elicited, even in 4‐year‐old children, yielding greater than expected spontaneous attention to relations. Children either generated or listened to an experimenter state the relationships between objects in a set of formal analogy problems, and then in a second task, selected object or relational matches according to their preference. Children tended to make object mappings, but those who generated relations on the first task selected relational matches more often on the second task, signaling that relational attention is malleable even in young children.     

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.     

Gender Differences in Mother-toddler and Father-toddler Verbal Initiations and Responses during a Caregiving and Play Context

Contextual variations in mother-child and father-child verbal communication were examined among 80 U.S. families from Kansas who were predominately Caucasian (85%) and middle-class. There were 41 girls and 39 boys between 15- and 18-months-old observed with their mothers and fathers in separate play and caregiving laboratory situations. Parent and child behaviors were coded for verbal initiation and response strategies. MANOVA’s revealed more differences between mother’s and father’s verbal communication strategies in the play context than the caregiving context. Boy’s and girl’s verbal communication was relatively similar across contexts. The interactions between gender and context are discussed in relation to gender role development in the family.     

Mother–child and father–child mutuality in two contexts: consequences for young children's peer relationships

This study examines the role that context plays in links between relative balance, or mutuality in parent–child interaction and children's social competence. Sixty‐three toddlers and their parents were observed in a laboratory play session and caregiving activity (i.e. eating snack). Mutuality was operationalised as the relative balance in (a) partners' compliance to initiations, and (b) partners' expression of positive emotion. Caregivers rated children's social competence with peers, and children's prosocial and aggressive behaviour with peers was observed in their childcare arrangement. Contextual differences were observed in the manifestation of parent–child mutuality, with both mother–child and father–child dyads displaying higher mutual compliance scores in the play context than in the caregiving context. Father–child dyads also displayed higher levels of shared positive emotion during play than during the caregiving context. There were no differences in a way that parent–child mutuality during play and caregiving was associated with children's social competence with peers. Overall, the results suggest that parent–child mutuality is a quality of parent–child interaction that has consistent links to children's peer competence regardless of the context in which it occurs.

The embodied nature of spatial perspective taking: Embodied transformation versus sensorimotor interference

Humans are able to mentally adopt the spatial perspective of others and understand the world from their point of view. We propose that spatial perspective taking (SPT) could have developed from the physical alignment of perspectives. This would support the notion that others have put forward claiming that SPT is an embodied cognitive process. We investigated this issue by contrasting several accounts in terms of the assumed processes and the nature of the embodiment. In a series of four experiments we found substantial evidence that the transformations during SPT comprise large parts of the body schema, which we did not observe for object rotation. We further conclude that the embodiment of SPT is best conceptualised as the self-initiated emulation of a body movement, supporting the notion of endogenous motoric embodiment. Overall our results are much more in agreement with an ‘embodied’ transformation account than with the notion of sensorimotor interference. Finally we discuss our findings in terms of SPT as a possible evolutionary stepping stone towards more complex alignments of socio-cognitive perspectives.     

Young children’s analogical reasoning across cultures: Similarities and differences

A cross-cultural comparison between U.S. and Hong Kong preschoolers examined factors responsible for young children’s analogical reasoning errors. On a scene analogy task, both groups had adequate prerequisite knowledge of the key relations, were the same age, and showed similar baseline performance, yet Chinese children outperformed U.S. children on more relationally complex problems. Children from both groups were highly susceptible to choosing a perceptual or semantic distractor during reasoning when one was present. Taken together, these similarities and differences suggest that (a) cultural differences can facilitate better knowledge representations by allowing more efficient processing of relationally complex problems and (b) inhibitory control is an important factor in explaining the development of children’s analogical reasoning.     

Prenatal and postnatal anxiety in Mexican women giving birth in Los Angeles

Examined psychosocial factors related to prenatal and postnatal anxiety in 291 primiparous Mexican women giving birth in Los Angeles. Characteristics of health care providers preferred by more anxious and less anxious women were also assessed. Higher prenatal anxiety was associated with less desire for an active role during labor, lower assertiveness, higher pain expectation at delivery, lack of support from family members other than the husband, and preferences for health care providers who are female and Latino. All groups of women preferred health care providers who provided good medical explanations and who were knowledgeable, friendly, and sympathetic. Postnatal anxiety was significantly lower than prenatal anxiety. Negative attitudes toward the baby and number of complications during labor and delivery, however, were related to postnatal anxiety adjusted for prenatal anxiety.
