Reaping the Rewards of Diversity: The Role of Identity Integration

How does diversity affect individuals and the groups in which they are embedded? This article examines this question using recent theory and research on Identity Integration (II). II refers to an individual's perceptions about whether two distinct social identities, or social groups to which individuals belong, are viewed as compatible (high II) or not (low II). A review of extant research suggests that individuals with high II are better at simultaneously accessing multiple identities and identity‐related knowledge and have improved well‐being and social outcomes. Expanding on this work, we argue that individuals who have higher II, and social collectives that foster II within their members, are more likely to reap the benefits of diversity.     

The impact of college‐level sex education on sexual knowledge,attitudes, and practices: The knowledge/sexual experimentation myth revisited

In recent years, many persons have opposed sex education believing that such courses will lead to increased participation in sexual intercourse by young people, but their fears are not supported by most previous research. The influence of sex education material integrated into functional marriage and family courses, however, has not been the subject of in‐depth, scientific investigations.

An anonymous questionnaire was administered to never‐married undergraduate students enrolled in a college‐level marriage and family course at a state university. A pretest and post‐test design was utilized with experimental groups of 50 women and 26 men and comparison groups of 60 women and 28 men.

The findings indicate that the sex education content had a significant impact on the experimental groups, especially for women. Substantial increases in knowledge regarding abortion and contraception, more favorable attitudes toward masturbation, and frequency of masturbation were reported by experimental group women as contrasted with comparison group women. Experimental group men indicated increased knowledge about female hygiene and contraception in contrast to comparison group men. From these findings, sex educators should be able to better meet the criticisms of sex education opponents given this greater understanding of the impact of sex education material on the sex lives of their students.     

Competitor effects in naming objects and famous faces

The prior production of an alternative name increases the time taken to name a famous face. For example, naming a picture of the comedy actor “John Cleese” by the name of the character he played in the TV series Fawlty Towers (Basil Fawlty) increases the time required to subsequently produce the name “John Cleese”. This effect has been termed the “nominal competitor effect”. In contrast prior production of a property associated with a famous person has no effect on naming speed. For example, prior production of the name of the TV series Fawlty Towers does not slow subsequent production of “John Cleese”. The experiments reported explored analogous effects in object naming. Experiment 1 examined the effects of prior production of an alternative name (e.g., from American English or British English) and a semantic associate on the time taken to name line drawings of objects. It was found that prior production of an alternative name slowed object naming, but prior production of the name of a semantic associate did not. Experiment 2 demonstrated that cueing a specific name (e.g., the British English name) was not a necessary condition for the nominal competitor effect on object naming. Experiment 3 demonstrated that the nominal competitor effect on naming famous faces was also observed under both cued and uncued naming instructions. The data from both object and face naming are interpreted within the terms of current models of speech production.     

Representational Pseudoneglect: A Review

Pseudoneglect, the tendency to be biased towards the left-hand side of space, is a robust and consistent behavioural observation best demonstrated on the task of visuospatial line bisection, where participants are asked to centrally bisect visually presented horizontal lines at the perceived centre. A number of studies have revealed that a representational form of pseudoneglect exists, occurring when participants are asked to either mentally represent a stimulus or explore a stimulus using touch in the complete absence of direct visuospatial processing. Despite the growing number of studies that have demonstrated representational pseudoneglect there exists no current and comprehensive review of these findings and no discussion of a theoretical framework into which these findings may fall. An important gap in the current representational pseudoneglect literature is a discussion of the developmental trajectory of the bias. The focus of the current review is to outline studies that have observed representational pseudoneglect in healthy participants, consider a theoretical framework for these observations, and address the impact of lifespan factors such as cognitive ageing on the phenomenon.     

The Before Baby Relationship Checkup: A Couples-Based Intervention to Reduce Relationship Risk Factors for Perinatal Mood and Anxiety Disorders

Relationship conflict and lack of partner support are risk factors for perinatal mood and anxiety disorders. An intervention to strengthen couples’ relationships before birth may reduce relationship risk factors for perinatal mood and anxiety disorders, though no research has explored this to date. The aims of this Stage 1 open-series non-experimental proof of concept study were to adapt the ‘Marriage Checkup’, an evidence-based intervention for relationship distress, as a preventative intervention for perinatal mood and anxiety disorders and to assess its feasibility and acceptability. Pregnant women receiving care at a university-based obstetric practice, and their partners, were recruited. Ten couples participated in the Before Baby Relationship Checkup, a personalized relationship health service offered in the obstetric clinic. Quantitative and qualitative data gathered suggests the intervention is feasible to implement in an obstetric setting, and acceptable to perinatal couples. Specific adaptations to the Marriage Checkup for perinatal couples are warranted and further testing is needed to evaluate efficacy.

     

Adaptive memory: fitness relevant stimuli show a memory advantage in a game of pelmanism

A pelmanism (matched-pairs) game was used in order to test the hypothesis that survival-relevant stimuli that are likely to have been present during human evolution (e.g., a snake in attack position) enjoy a memory advantage over other survival-relevant (but “modern”) stimuli (e.g., a threatening image of a gunman). Survival-relevant stimuli were matched for arousal and presented in one of two 5 x 4 grids, along with filler items. Participants were asked to match the pairs in the grids by clicking on successive squares to reveal stimuli. Participants made significantly fewer errors when matching evolutionarily relevant survival stimuli than when matching the other stimuli. Additionally, on incorrect trials, the attempted matches were significantly closer to the actual locations of evolutionarily relevant targets than to those of other stimuli. The results suggest that objects that likely posed a consistent threat throughout human evolutionary history are better remembered than other, equally arousing and survival-relevant, stimuli.

Visuospatial bootstrapping: Long-term memory representations are necessary for implicit binding of verbal and visuospatial working memory

It has recently been shown that presenting additional visuospatial information alongside to-be-remembered numbers in a digit span task enhances participants’ memory for those items. However, the mechanisms behind this visuospatial bootstrapping effect have remained unspecified. In this article, we report evidence that this effect involves an integration of information from verbal and visuospatial temporary memory with long-term-memory (LTM) representations and that the existence of a relevant LTM representation is necessary for bootstrapping to occur.
