Adult attachment,the transition to parenthood,and depressive symptoms

Testing a model suggested by J. Bowlby (1988), this study investigated how a personal vulnerability (attachment ambivalence) interacts with perceptions of deficient spousal support before and during a major life stressor (the transition to parenthood) to predict pre-to-postnatal increases in depressive symptoms. Highly ambivalent women who entered parenthood perceiving either less support or greater anger from their husbands experienced pre-to-postnatal increases in depressive symptoms at 6 months postpartum. The associations between these 2 prenatal interaction terms and pre-to-postnatal increases in depressive symptoms were mediated by perceptions of declining spousal support across the transition period. Moreover, for highly ambivalent women, the association between prenatal and postnatal depression scores was mediated by perceptions of the amount of support available from their husbands.     

Using Concept Mapping to Operationalize Mental Well-Being for Men and Boys

A primary purpose of many prevention-oriented interventions is to improve the general well-being and quality of life for individuals and their communities. Unfortunately, well-being is often poorly defined, with definitions embracing related issues of quality of life, happiness, and physical health. Mental well-being as a concept is also poorly defined, particularly for different population groups. As part of a larger study to assess community-level prevention efforts aimed at men and boys, a participatory approach was used to operationalize mental well-being from a male-centered, community-based perspective using concept mapping. A set of 96 statements perceived as important aspects of mental well-being for men and boys were developed and sorted by 90 participants from the study communities. The 8-cluster solution was selected as the most parsimonious and the best conceptual fit in relation to the mental well-being concept, namely, positive self-worth, supportive community, community connections, positive masculinity, responsive institutions, strong social connection, dignity and respect, and safety. These eight clusters of mental well-being, which were classified into two overarching domains of socio-environmental and emotional well-being, can provide a basis by which to assess community-based programs aimed at this population.     

Child care effects in context: quality, stability, and multiplicity in non-maternal child care arrangements during the first 15 months of life

Main and interactive effects of child care quality, stability, and multiplicity on infants' attachment security, language comprehension, language production, and cognitive development at 15 months were examined using data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care. Thirty-nine percent of the infants in this sample experienced arrangement change, and 46% experienced multiple concurrent arrangements during the first 15 months. As in previous studies, concurrent quality, average quality, and quality slope significantly predicted cognitive and language development. There was some evidence that certain forms of unstable child care--including nonfamilial change, familial to nonfamilial change, and within-home to out-of-home change--were associated with poorer language development. Multiple child care arrangements involving family members positively predicted language comprehension; multiple care involving a mix of family and non-relative caregivers negatively predicted language comprehension. Interactions among variables exhibited "effects in context." That is, under conditions of low or moderate quality in the primary care arrangement, the use of fewer multiple arrangements was associated with higher language scores; under conditions of high primary care quality, the use of more multiple arrangements was associated with higher language scores.     

Landscaping analyses of the ROC predictions of discrete-slots and signal-detection models of visual working memory

A fundamental issue concerning visual working memory is whether its capacity limits are better characterized in terms of a limited number of discrete slots (DSs) or a limited amount of a shared continuous resource. Rouder et al. (2008) found that a mixed-attention, fixed-capacity, DS model provided the best explanation of behavior in a change detection task, outperforming alternative continuous signal detection theory (SDT) models. Here, we extend their analysis in two ways: first, with experiments aimed at better distinguishing between the predictions of the DS and SDT models, and second, using a model-based analysis technique called landscaping, in which the functional-form complexity of the models is taken into account. We find that the balance of evidence supports a DS account of behavior in change detection tasks but that the SDT model is best when the visual displays always consist of the same number of items. In our General Discussion section, we outline, but ultimately reject, a number of potential explanations for the observed pattern of results. We finish by describing future research that is needed to pinpoint the basis for this observed pattern of results.     

For a New Look at ‘Lexical Errors’: Evidence from Semantic Approximations with Verbs in Aphasia

The ability to understand the similarity between two phenomena is fundamental for humans. Designated by the term analogy in psychology, this ability plays a role in the categorization of phenomena in the world and in the organisation of the linguistic system. The use of analogy in language often results in non-standard utterances, particularly in speakers with aphasia. These non-standard utterances are almost always studied in a nominal context and considered as errors. We propose a study of the verbal lexicon and present findings that measure, by an action-video naming task, the importance of verb-based non-standard utterances made by 17 speakers with aphasia (“la dame déshabille l’orange”/the lady undresses the orange, “elle casse la tomate”/she breaks the tomato). The first results we have obtained allow us to consider these type of utterances from a new perspective: we propose to eliminate the label of “error”, suggesting that they may be viewed as semantic approximations based upon a relationship of inter-domain synonymy and are ingrained in the heart of the lexical system.     

Fathers' and Mothers' Emotional Accessibility and Youth's Developmental Outcomes

ABSTRACT

This study examined the association between parents' emotional accessibility and youth's functioning. Participants included 154 parents who completed measures of parental emotional accessibility and their children's emotional and behavioral problems. Results showed that mothers are more emotionally accessible to their children. Mothers' emotional accessibility was associated negatively with youth's emotional and behavioral problems; whereas, fathers' emotional accessibility was associated with only youth's behavioral problems. This study highlights the importance of examining parental emotional accessibility when studying youth's development, utilizing parental perceptions to learn about youth and family functioning, and actively including fathers in family research studies.     

The influence of relationship status, mate seeking, and sex on intrasexual competition

Researchers have little explored individuals' perceptions of same-sex attractiveness in terms of the influence of relationship status. By using intrasexual competition as a conceptual framework, the authors predicted that romantically involved individuals would protect their relationship by derogating competitors. Although previous researchers have strongly predicted this result, in the present study the relationship status had a negligible impact on competition, for which relationship commitment, sociosexual orientation, and self-monitoring did not account. Also, among uninvolved individuals, the authors expected those individuals seeking mates would use competitor derogation more than would those individuals not seeking mates, but there was no significant difference. Finally, because the vehicle for this investigation was attractiveness, an area in which women compete, the authors proposed that women would derogate more fiercely than would men. However, the results did not support this hypothesis either. The authors discuss future directions for research.     

Cognitive and emotional processes during dreaming: a neuroimaging view

Dream is a state of consciousness characterized by internally-generated sensory, cognitive and emotional experiences occurring during sleep. Dream reports tend to be particularly abundant, with complex, emotional, and perceptually vivid experiences after awakenings from rapid eye movement (REM) sleep. This is why our current knowledge of the cerebral correlates of dreaming, mainly derives from studies of REM sleep. Neuroimaging results show that REM sleep is characterized by a specific pattern of regional brain activity. We demonstrate that this heterogeneous distribution of brain activity during sleep explains many typical features in dreams. Reciprocally, specific dream characteristics suggest the activation of selective brain regions during sleep. Such an integration of neuroimaging data of human sleep, mental imagery, and the content of dreams is critical for current models of dreaming; it also provides neurobiological support for an implication of sleep and dreaming in some important functions such as emotional regulation.
