Getting ready: Results of a randomized trial of a relationship‐focused intervention on the parent–infant relationship in rural early head start

The purpose of this study is to investigate the effects of a relational intervention (the Getting Ready intervention) on parenting behaviors supporting the parent–infant relationship for families enrolled in Early Head Start home‐based programming. Two‐hundred thirty‐four parents and their children participated in the randomized study, with 42% of parents reporting education of less than a high‐school diploma. Brief, semistructured parent–child interaction tasks were videotaped every 4 months over a16‐month intervention period. Observational codes of parent–infant relationship behaviors included quality of three parental behaviors: warmth and sensitivity, support for learning, and encouragement of autonomy; two appropriateness indicators: support for learning and guidance/directives; and one amount indicator: constructive behaviors. Parents who participated in the Getting Ready intervention demonstrated higher quality interactions with their children that included enhanced quality of warmth and sensitivity, and support for their children's autonomy than did parents in the control group. They also were more likely to use appropriate directives with their children and more likely to demonstrate appropriate supports for their young children's learning. Results indicate an added value of the Getting Ready intervention for Early Head Start home‐based programming for families of infants and toddlers.     

Childhood abuse and neglect and cognitive flexibility in adolescents

Childhood maltreatment (CM) has been associated with diminished executive functioning in children and adults; however, there is a relative paucity of study of executive function in adolescents exposed to CM. Yet, executive dysfunction in adolescence may have important adverse consequences including increased vulnerability to risky behaviors and impaired school functioning. This study investigates the relationship between self-reported CM and an executive function, cognitive flexibility, in adolescents without identified psychiatric disorders. Effects of physical and emotional, abuse and neglect, maltreatment subtypes were explored. Thirty adolescents ages 12-17 years, 50% females, completed the retrospective self-report Childhood Trauma Questionnaire (CTQ) and were administered the Wisconsin Card Sorting Test (WCST). Correlational analyses assessed the relationship between WCST perseverative error scores norm-referenced for age and education with CTQ total scores. The relationship with nonperseverative errors, as well as with physical and emotional abuse and neglect CM subscores, were explored. Total CTQ scores showed significant associations with perseverative errors on the WCST, but not with nonperseverative errors. Significant associations with perseverative errors were seen for physical abuse and physical neglect among the CTQ subscales. The results suggest both physical abuse and physical neglect are associated with diminished cognitive flexibility in adolescents. These effects were detected in adolescents without identified psychiatric diagnoses suggesting the importance of considering executive dysfunction in adolescents exposed to CM who may not meet diagnostic criteria for an Axis I disorder and that tests of perseverative errors, such as those of the WCST, may be sensitive indicators of this dysfunction.     

Emotional health predictors of substance use initiation during middle school

This study aimed to evaluate whether emotional health factors, including anxiety and depression, stress, and social support, are associated with earlier youth initiation of alcohol and illicit substances during middle school (from the sixth to the eighth grade). Data for this study were from the Developmental Pathways Project, a longitudinal study of 521 youth sampled from the Seattle Public Schools. Discrete time survival analyses were used to assess the effects of depression, anxiety, stress, and support on initiation of substance use, measured every 6 months at five time points between sixth and eighth grade. Youth who had initiated prior to sixth grade had significantly higher levels of depressive symptoms. In multivariate survival analyses controlling for child race/ethnicity, gender, and socioeconomic status, and accounting for conduct problems, youth who reported higher levels of separation anxiety/panic symptoms were at decreased risk for early alcohol initiation. Children with higher levels of perceived teacher support had a significantly lower risk of alcohol initiation during early follow-up periods. Recent stressful life events in Grade 6 were associated with significantly greater risk of initiating an illicit substance by Grade 8. The current findings highlight the role of stress in the initiation of illicit substance use and suggest that teacher support is associated with lower risk for very early alcohol use. Future research examining anxiety as a predictor of substance use should distinguish between subtypes of anxiety.     

What a nostril knows: olfactory nerve-evoked AMPA responses increase while NMDA responses decrease at 24-h post-training for lateralized odor preference memory in neonate rat

Increased AMPA signaling is proposed to mediate long-term memory. Rat neonates acquire odor preferences in a single olfactory bulb if one nostril is occluded at training. Memory testing here confirmed that only trained bulbs support increased odor preference at 24 h. Olfactory nerve field potentials were tested at 24 h in slices from trained and untrained bulbs. A larger AMPA component and a smaller NMDA component characterized responses in the bulb receiving odor preference training. Field potential changes were not seen in a bulbar region separate from the lateral odor-encoding area. These results support models in which memory is mediated by increased olfactory nerve-mitral cell AMPA signaling, and memory stability is promoted by decreased NMDA-mediated signaling.     

Cortical asymmetries in speech perception: what's wrong,what's right and what's left?

Over the past 30 years hemispheric asymmetries in speech perception have been construed within a domain-general framework, according to which preferential processing of speech is due to left-lateralized, non-linguistic acoustic sensitivities. A prominent version of this argument holds that the left temporal lobe selectively processes rapid/temporal information in sound. Acoustically, this is a poor characterization of speech and there has been little empirical support for a left-hemisphere selectivity for these cues. In sharp contrast, the right temporal lobe is demonstrably sensitive to specific acoustic properties. We suggest that acoustic accounts of speech sensitivities need to be informed by the nature of the speech signal and that a simple domain-general vs. domain-specific dichotomy may be incorrect.     

The effects of print exposure on sentence processing and memory in older adults: Evidence for efficiency and reserve

The present study was an examination of how exposure to print affects sentence processing and memory in older readers. A sample of older adults (N = 139; Mean age = 72) completed a battery of cognitive and linguistic tests and read a series of sentences for recall. Word-by-word reading times were recorded and generalized linear mixed effects models were used to estimate components representing attentional allocation to word-level and textbase-level processes. Older adults with higher levels of print exposure showed greater efficiency in word-level processing and in the immediate instantiation of new concepts, but allocated more time to semantic integration at clause boundaries. While lower levels of working memory were associated with smaller wrap-up effects, individuals with higher levels of print exposure showed a reduced effect of working memory on sentence wrap-up. Importantly, print exposure was not only positively associated with sentence memory, but was also found to buffer the effects of working memory on sentence recall. These findings suggest that the increased efficiency of component reading processes that come with life-long habits of literacy buffer the effects of working memory decline on comprehension and contribute to maintaining skilled reading among older adults.     

Age-related neural differences in affiliation and isolation

While previous aging studies have focused on particular components of social perception (e.g., theory of mind, self-referencing), little is known about age-related differences specifically for the neural basis of perception of affiliation and isolation. This study investigates age-related similarities and differences in the neural basis of affiliation and isolation. Participants viewed images of affiliation (groups engaged in social interaction) and isolation (lone individuals), as well as nonsocial stimuli (e.g., landscapes), while making pleasantness judgments and undergoing functional neuroimaging (BOLD fMRI). Results indicated age-related similarities in response to affiliation and isolation in recruitment of regions involved in theory of mind and self-referencing (e.g., temporal pole, medial prefrontal cortex). Yet age-related differences also emerged in response to affiliation and isolation in regions implicated in the theory of mind, as well as self-referencing. Specifically, in response to isolation versus affiliation images, older adults showed greater recruitment than did younger adults of the temporal pole, a region that is important for retrieval of personally relevant memories utilized to understand others' mental states. Furthermore, in response to images of affiliation versus isolation, older adults showed greater recruitment than did younger adults of the precuneus, a region implicated in self-referencing. We suggest that age-related divergence in neural activation patterns underlying judgments of scenes depicting isolation versus affiliation may indicate that older adults' theory of mind processes are driven by retrieval of isolation-relevant information. Moreover, older adults' greater recruitment of the precuneus for affiliation versus isolation suggests that the positivity bias for emotional information may extend to social information involving affiliation.     

Psychoanalysis and the social construction of gender and sexuality (discussion)

Abstract

Grey C.C. Psychoanalysis and the Social Construction of Gender and Sexuality. Inter Forum Psychoanal 1992; 1:74-78. Stockholm. ISSN 0803-706X

The traditional psychoanalytic concept of homosexuality as pathology, as well as our etiological speculations, have been seriously challenged by scientific research. An alternative is proposed here viewing sexual identities (whether hetero- or homo-) as socially constructed. The meaning of sexual behavior thus arises from the interplay between unique individual experience and the cultural milieu in which the individual develops. The effects of exclusion and stigmatization are particularly salient to the identities of homosexual men and women in Western society, as are the effects of gender ideologies.     

The Influence of Attentional Style and Risk Perceptions on Intentions to Undergo Prophylactic Oophorectomy Among First-Degree Relatives

This study examined the predictors of women's intentions to undergo prophylactic oophorectomy. Eighty female first-degree relatives (FDRs) of ovarian cancer patients completed a measure of attentional style upon enrollment into a Family Risk Assessment Program. Following participation, measures of cancer risk perceptions, perceived benefits and costs of surgery, and intentions to undergo preventive surgery were obtained. Hierarchical regression analyses indicated that a high monitoring attentional style, as well as greater perceived risk of ovarian cancer and greater perceived benefits of the procedure, was associated with greater intentions to undergo prophylactic oophorectomy. In addition, a significant interaction between attentional style and perceived risk revealed that high monitors who felt at increased risk for ovarian cancer were less inclined to undergo surgery, whereas low monitors who perceived themselves to be at increased risk were more inclined to undergo surgery. The implications of the results for the design of counseling interventions are discussed.     

Instructed faking of the HEXACO reduces facet reliability and involves more Gc than Gf

Research on the role of intelligence in the capacity to fake personality tests tends to use the Big Five and g-factor models of personality and intelligence. The current study (N = 185 university students) examines instructed faking on the HEXACO and separately considers the role of fluid intelligence (Gf) and crystallized intelligence (Gc). Results demonstrate that: (a) participants can fake the HEXACO domains and facets to about the same extent as the Big Five; (b) faking has little effect on domain reliability but reduces facet reliability; and (c) faking involves Gc to a much greater degree than Gf. Results are discussed in terms of practical applications of facet scores, and process models of faking.
