Dichotic listening and left-right confusion

The present study examined the relationship between individual differences in dichotic listening (DL) and the susceptibility to left-right confusion (LRC). Thirty-six men and 59 women completed a consonant-vowel DL test, a behavioral LRC task, and an LRC self-rating questionnaire. Significant negative correlations between overall DL accuracy and LRC rates in men (behavioral task) and self-ratings in women, indicated that the more participants struggled with left-right discrimination, the fewer DL syllables they reported correctly. However, there was no relationship between LRC and the typical right ear advantage. Thus, there is a sex- and task-dependent relationship between LRC and overall DL accuracy, but not between LRC and ear asymmetry. It is concluded that (a) atypical ear asymmetries, as in certain clinical populations, cannot be explained by associated deficits in left-right discrimination, and (b) LRC can negatively affect task performance, even when participants do not have to make explicit "left" versus "right" decisions.     

A Qualitative Assessment of the Sex Education Needs of Married Iranian Women

Despite a comprehensive reproductive health program there is little sex education available in Iran. In this article we present results of a study conducted to identify content area for a proposed sex education program for married Iranian women. Twenty-one married female clients (23–45 years) and 18 reproductive health providers, recruited from urban health clinics in Tehran using non-probability sampling, participated in four focus group discussions. Sexual health information needs related to reproductive tract and sexually transmitted infections, “acceptability” of certain sexual practices such as oral and anal intercourse, and the sexual response cycles and physiology of men and women. Women’s sexual concerns related to communication, incompatibility of sexual interests and desire, and their ability to maintain a strong marriage. Two themes cut across women’s responses to all questions: modesty and maintaining a strong marriage. Results contributed to the design of a sex education program that addressed the specific information needs and concerns of Iranian women.     

Integrating Sex and Couples Therapy: A Multifaceted Case History

Traditionally, sexuality has not been a focus in couples therapy training, research, or practice, although it is an important, often complex issue for many couples. This article tells the story of a couple presenting for sex therapy due to their unconsummated marriage, and is told to exemplify how sex therapy and couples therapy can be integrated in order to best meet the needs of couples. As the story unfolds, the multilayered facets of the presenting issue are revealed. The therapy incorporates and weaves together family of origin history, intrapsychic and cognitive issues, relational dynamics, patterns of interaction, and physiological/medical concerns into a postmodern couples therapy with behavioral interventions. This combined approach recognizes the value of each method on its own and their greater usefulness when blended together.     

An experimental test of the effects of gender constancy on sex typing

This study provides an experimental test of the hypothesis that level of gender constancy understanding affects children’s sex typing. Preschool-age children (N = 62, mean age = 47 months) were randomly assigned to experimental lessons that taught that biological traits (including gender) are either fixed (pro-constancy condition) or mutable (anti-constancy condition). Posttests revealed that the lessons were effective; children in the pro-constancy condition showed higher gender constancy and appearance–reality distinction scores than did children in the anti-constancy condition. Sex typing did not, however, differ between treatment conditions at immediate and 3-month posttesting.     

Value priorities and preferences for a relationship partner

Despite extensive research into preferences for a romantic partner, previous work has not addressed the role of individual values in informing desires for a partner. The present study employed a recent comprehensive model of values [Schwartz, S. H. (1994). Beyond individualism-collectivism: new cultural dimensions of values. In U. Kim, H. C. Triandis, C. Kagitcibasi, S-C. Choi, & G. Yoon (Eds.), Individualism and collectivism: theory, method and application (pp. 81–119). Newbury Park, CA: Sage] to examine the role of values and sex, age and education in partner preferences. One hundred general population respondents from two British towns completed the Schwartz Value Survey and rated the desirability of 13 partner characteristics. Correlational analyses confirmed 12 of the 17 expected relationships between value scores and partner preferences whilst regressions conducted on three preference factors underlined the importance of the sex and education of the respondent in their rating of some partner ideals. We conclude by considering the need for future studies of partner preferences to combine the study of values with a range of demographic factors studied across a number of cultural settings.     

Sex differences in the IQ-white matter microstructure relationship: A DTI study

Sex differences in the relationship between general intelligence and brain structure are a topic of increasing research interest. Early studies focused mainly on gray and white matter differences using voxel-based morphometry, while more recent studies investigated neural fiber tracts using diffusion tensor imaging (DTI) to analyze the white matter microstructure. In this study we used tract-based spatial statistics (TBSS) on DTI to test how intelligence is associated with brain diffusion indices and to see whether this relationship differs between men and women. 63 Men and women divided into groups of lower and higher intelligence were selected. Whole-brain DTI scans were analyzed using TBSS calculating maps of fractional anisotropy (FA), radial diffusivity (RD), and axial diffusivity (AD). The results reveal that the white matter microstructure differs between individuals as a function of intelligence and sex. In men, higher intelligence was related to higher FA and lower RD in the corpus callosum. In women, in contrast, intelligence was not related to the white matter microstructure. The higher values of FA and lower values of RD suggest that intelligence is associated with higher myelination and/or a higher number of axons particularly in men. This microstructural difference in the corpus callosum may increase cognitive functioning by reducing inter-hemispheric transfer time and thus account for more efficient brain functioning in men.     

Up by upwest: Is slope like north?

Terrain slope can be used to encode the location of a goal. However, this directional information may be encoded using a conceptual north (i.e., invariantly with respect to the environment), or in an observer-relative fashion (i.e., varying depending on the direction one faces when learning the goal). This study examines which representation is used, whether the sensory modality in which slope is encoded (visual, kinaesthetic, or both) influences representations, and whether use of slope varies for men and women. In a square room, with a sloped floor explicitly pointed out as the only useful cue, participants encoded the corner in which a goal was hidden. Without direct sensory access to slope cues, participants used a dial to point to the goal. For each trial, the goal was hidden uphill or downhill, and the participants were informed whether they faced uphill or downhill when pointing. In support of observer-relative representations, participants pointed more accurately and quickly when facing concordantly with the hiding position. There was no effect of sensory modality, providing support for functional equivalence. Sex did not interact with the findings on modality or reference frame, but spatial measures correlated with success on the slope task differently for each sex.     

Sex differences in the effects of visual contact and eye contact in negotiations

Previous research has proposed that the ability to see others would benefit negotiations. We argue that this view is too narrow and that the impact of visual contact on negotiated agreements depends on the meaning individuals ascribe to either its presence or absence. Based on previous research showing that females are more likely to understand others in the presence of visual contact while males understand others better in the absence of visual contact, we explore how visual contact, eye contact, and sex affect the quality of negotiated agreements in a meta-analysis (Study 1) and a laboratory experiment (Study 2). The two studies combined show that because direct communication via the face facilitates a shared understanding for two unacquainted females, their agreements are of higher quality when they have visual contact compared to when they do not (Study 1), and if they have visual contact, their agreements are better when they have eye contact than when they do not (Study 2). Because communication via the face increases discomfort between two unacquainted males, their agreements are of higher quality when they do not have visual contact (Study 1), and if they do have visual contact, their agreements are better when they have no eye contact than when they do (Study 2).
