Psychological gender, hand preferences, and sex differences in book-carrying styles

Individuals with stronger sex-role identities may be expected to show greater conformity to sex-typed behaviors. Proceeding from this assumption, the sex-role status and sex of students using different styles of carrying books were compared. This study also examined whether over-all hand preference or age were related to carrying styles or sex-role status. Subjects completed a questionnaire comprised of the 24-item Personal Attributes Questionnaire of Spence and Helmreich, a 6-item scale of hand preference and a self-rating of sex-role identity. Afterwards, each subject's carrying style was covertly observed and recorded. Most subjects carried their materials in a sex-typical way or in book bags (for which no sex-typed carrying styles were discovered). As in previous studies, men in this study scored higher than women on masculinity and androgyny and lower on femininity. Hand preference was not related to sex-role status. Carrying style was not significantly correlated with any of the predictor variables for men, perhaps because almost no variance in carrying style was observed among them. Women who used masculine carrying styles tended to be older, have greater instrumentality, and a more masculine identity.     

Organism-environment mutuality epistemics,and the concept of an ecological niche

The concept of an ecological niche (econiche) has been used in a variety of ways, some of which are incompatible with a relational or functional interpretation of the term. This essay seeks to standardize usage by limiting the concept to functional relations between organisms and their surroundings, and to revise the concept to include epistemic relations. For most organisms, epistemics are a vital aspect of their functional relationships to their surroundings and, hence, a major determinant of their econiche. Rejecting the traditional dualism of organism and environment, an econiche is defined as the reciprocal (dual) of a functionally specified class of organisms (FSTU). From this perspective, an econiche necessarily implies a certain type of organism, and a class of functionally similar organisms implies a special econiche.The econiche concept is also discussed in relation to other ecological terms that reflect the distributional patterns of organisms, such as habitat, and the concept of an empty niche is criticized.Special thanks are due to Michael Turvery for his part in many stimulating discussions of some of the problems and concepts addressed in this paper. I am also grateful to him and to Claudia Carello, Tim Johnston, Bill Mace, Bernard Patten, Ed Reed, Robert E. Shaw, Bill Warren, and an anonymous reviewer for their comments on earlier drafts of this paper.     

Left-handedness and spatial reasoning abilities: The deficit hypothesis revisited

Left-handers with an inverted handwriting posture have been found by Levy and Reid to have relatively bilateral representation of tachistoscopically tested verbal and spatial functions. On the assumption that such bilateral representation is inefficient, it was hypothesized that left-inverted subjects (N = 20) would score lower than left- and right-handers with normal handwriting postures (Ns = 64, 66 respectively) on spatial reasoning. Results were consistent with the hypothesis. Possible alternative explanations and directions for future research are outlined.     

Relationship problems and extradyadic romantic and sexual activity in a web‐sample of Norwegian men and women

The purpose of this paper is to describe the prevalence of self‐reported types of extradyadic romantic and sexual activity among adult Norwegians and to explore the role of infidelity in breaking up a permanent relationship. The results are based on 1,001 web interviews with persons ranging in age from 18 to 67 years. The majority of respondents reported having engaged in some kind of extradyadic romantic and/or sexual activity. Forty‐five percent of the women and 39% of the men claimed they had experienced a previous breakup from a marriage or cohabiting relationship. Among those aged 50 years or older, the most important reasons for breaking up a previous relationship were infidelity (38%) and lost love (38%). More men (44%) than women (33%) reported infidelity. Respondents younger than 50 years were more motivated by boredom. Among respondents below the age of 50 years, the most frequently reported reasons for considering termination of a present relationship were quarreling (37%), poor sex life (29%), and “other” reasons (25%). Accordingly, infidelity was not identified as an essential factor for considering a breakup from the present relationship.     

Digital speech recording and playback system using a multiprocessor architecture

This paper describes a digital speech recording system capable of digitizing, storing, and playing back speech signals of arbitrary duration. The maximum duration for continuous speech processing is limited only by disk storage capacity. The system is based on a multiprocessor architecture, with a main processor responsible for file processing and outboard processor I/O control. As implemented, the main processor is a DEC LSI-11/23 microcomputer with 1 MB of main memory and a large-capacity Winchester disk. The outboard processor is an Intel 8085 with 2K local memory for speech buffering. Digitization is accomplished using logarithmic PCM at 8-kHz sampling frequency. Interprocessor communication is achieved with a 16-bit parallel data bus, and the necessary electrical connections and handshaking signals are discussed in detail. The local software modules are described, with attention given to timing and communications protocol considerations.     

Motion sickness history, food neophobia, and sensation seeking

Motion sickness is believed to be caused by conflicting sensory signals, a situation that mimics the effects of ingesting certain toxins. Thus, one might suspect that individuals who have experienced a relatively high frequency of motion sickness may be particularly vigilant about avoiding anything that produces nausea, induding potentially nauseating toxins. Consequently, they may be more resistant to trying new foods, i.e., be more food neophobic, since unfamiliar foods can have unexpected adverse effects due to toxins or allergens. Likewise, many highly stimulating experiences can trigger motion sickness, so individuals who are more susceptible may be more prone to avoid such experiences, i.e., be less sensation seeking. Finally, it was expected that food neophobia would be more frequent in individuals low on sensation seeking tendencies. Self-reported motion sickness history in 308 adults (M= 18.8 yr.; SD = 1.6) was correlated with scores on the Arnett Inventory of Sensation Seeking and the Food Neophobia Scale. As predicted, greater history of motion sickness was associated with lower Sensation Seeking scores. Food Neophobia was not correlated with motion sickness history but, as expected, was negatively correlated (r = -.42) with scores on Sensation Seeking. Further research is recommended that measures actual sensitivity to motion sickness.     

Sex-linked carrying styles and the attribution of homosexuality.

We used pairs of slides showing 3 women and 3 men displaying 2 sex linked carrying styles to examine differences in the attribution of homosexuality as a consequence of behavioral displays that are either sex typical or sex atypical. We hypothesized that the participants would be less likely to view targets displaying sex-typical behaviors as gay men or as lesbians. Each of 2 groups of U.S. university students rated targets in 6 slides on homosexuality and 3 other traits. The mean difference in rated homosexuality for typical versus atypical carrying styles was small but statistically significant. Thus, the results provide some empirical support for the common belief that effeminate men and masculine women are more likely to be seen as homosexual, at least by U.S. university students.     

Advertising Effectiveness and Attitude Change Vary as a Function of Working Memory Capacity

Prior research has confirmed that the amount of attention paid to an advertisement will influence its effectiveness when it comes to changing consumer attitudes. This study expands on this understanding by exploring how individual differences in the ability to control attention (i.e., working memory capacity; WMC) might further moderate the effect of attention on advertising. Participants who varied in WMC were evaluated on their attitudes towards a consumer brand before and after viewing a video advertisement. While the advertisement did make participants more positive towards the product overall, this change in attitude was directly related to participants' ability to control attention and the degree to which the ad fostered the activation of autobiographical memories. Further, these changes in attitude were unrelated to how well the ad was remembered. This suggests that individual differences in attentional control can influence how advertisements impact customer attitude and the acceptance of persuasive messaging.
