Sensitive maintenance: a cognitive process underlying individual differences in memory for threatening information

Dispositional styles of coping with threat influence memory for threatening information. In particular, sensitizers excel over repressors in their memory for threatening information after long retention intervals, but not after short ones. We therefore suggested that sensitizers, but not repressors, employ active maintenance processes during the retention interval to selectively retain threatening material. Sensitive maintenance was studied in 2 experiments in which participants were briefly exposed to threatening and nonthreatening pictures (Experiment 1, N = 128) or words (Experiment 2, N = 145). Following, we administered unannounced recognition tests before and after an intervening task that generated either high or low cognitive load, assuming that high cognitive load would impede sensitizers' memory maintenance of threatening material. Supporting our hypotheses, the same pattern of results was obtained in both experiments: Under low cognitive load, sensitizers forgot less threat material than repressors did; no such differences were observed under high cognitive load.     

The Influence of Two Cognitive-Linguistic Variables on Incidental Word Learning in 5-Year-Olds

The relation between incidental word learning and two cognitive-linguistic variables—phonological memory and phonological awareness—is not fully understood. Thirty-five typically developing, 5-year-old, preschool children participated in a study examining the association between phonological memory, phonological awareness, and incidental word learning. Children were exposed to target words in a read-aloud story that accompanied a wordless picture book. Target word comprehension was assessed before and after two readings of the story. Phonological awareness predicted incidental word learning but phonological memory did not. The influence of phonological awareness and phonological memory on word learning may be dependent on the demands of the word learning task.     

Of sex roles and strollers: Female and male attention to toddlers at the zoo

Research supports the conclusion that adults interact differently with children of different sexes. Laboratory and home studies indicate that fathers/adult males are the primary agents of sex typing and that mothers/adult females are the primary caretakers, especially regarding the managerial aspects of child care. Little attention, however, has been directed at the public display of these differences and their covariance. Observations were made of 6414 visitors to the Sacramento zoo, with 524 adult females, 524 adult males, and 524 toddler triumvirates targeted for specific analyses of adult-child interactions and caretaking behaviors. Males were significantly more likely to carry female toddlers than male toddlers, while females made no such distinction. Adult females were more likely than adult males to push the child's stroller. Related research on the father's role in sex-typing behavior and the role of the division of child care between parents in the maintenance and reproduction of gender roles is discussed.This research was supported by a University of California at Davis Faculty Research Grant to the second author. We thank R. J. Mitchell for his contributions, both in and out of his stroller.     

DIMENSIONS OF FAMILY RELATIONSHIPS ASSOCIATED WITH DEPRESSIVE SYMPTOMATOLOCY IN MOTHERS OF YOUNG CHILDREN

Although mothers of young children have a higher incidence of depressive symptomatology than do either women who are not mothers or men, very little is known about the psychological nature of this phenomenon. This study examines the way in which psychological dimensions of family relationships are associated with or contribute to this increased risk in married Caucasian mothers raising first-born children. The relationships between maternal depressive symptomatology and recollections of parental relationships during childhood, marital satisfaction, and maternal separation anxiety were examined. Hierarchical regression analyses revealed that these three factors explained 35.5% of the variance in maternal depressive symptomatology. These results, in addition to significant zero-order correlations, are discussed in light of the existing psychological literature.     

Using Prolonged Exposure and Cognitive Processing Therapy to Treat Veterans With Moral Injury-Based PTSD: Two Case Examples

Moral injury refers to acts of commission or omission that violate individuals’ moral or ethical standards. Morally injurious events are often synonymous with psychological trauma, especially in combat situations—thus, morally injurious events are often implicated in the development of posttraumatic stress disorder (PTSD) for military service members and veterans. Although prolonged exposure (PE) and cognitive processing therapy (CPT) have been well established as effective treatments for veterans who are struggling with PTSD, it has been suggested that these two evidence-based therapies may not be sufficient for treating veterans whose PTSD resulted from morally injurious events. The purpose of this paper is to detail how the underlying theories of PE and CPT can account for moral injury-based PTSD and to describe two case examples of veterans with PTSD stemming from morally injurious events who were successfully treated with PE and CPT. The paper concludes with a summary of challenges that clinicians may face when treating veterans with PTSD resulting from moral injury using either PE or CPT.     

The role of shape recognition in figure/ground perception in infancy

In this study we sought to determine whether infants, like adults, utilize previous experience to guide figure/ground processing. After familiarization to a shape, 5-month-olds preferentially attended to the side of an ambiguous figure/ground test stimulus corresponding to that shape, suggesting that they were viewing that portion as the figure. Infants’ failure to exhibit this preference in a control condition in which both sides of the test stimulus were displayed as figures indicated that the results in the experimental condition were not due to a preference between two figure shapes. These findings demonstrate for the first time that figure/ground processing in infancy is sensitive to top-down influence. Thus, a critical aspect of figure/ground processing is functional early in life.
