The mental nose and the Pinocchio effect: Thermography,planning, anxiety,and lies

We applied thermography to cognitive neuropsychology, particularly as a somatic marker of subjective experience during cognitive and emotional tasks. We found significant correlations between changes in facial temperature and mental set. Specifically, the temperature of the nose tended to decrease during emotional tasks and increase during cognitive tasks. However, for stress tests or high arousal reactions to emotional stimuli, the direction of the thermal change depended on the nature of the setting, real or simulated. Detection of deception is a mixed field where cognitive effort, physiological stress, and empathy have evolved, affecting the direction of the thermal variation—higher or lower temperature of the tip of the nose and forehead. We found that the temperature change of the nose and forehead may enable detecting when people lie about facts (the Pinocchio effect markers). In general, one important contribution is to recover mental thermometry as a potent tool for neurocognitive studies.     

Heteronormative Relationship Education for Same‐Gender Couples

In recent years, same‐gender group‐based relationship education has emerged as a viable intervention to prevent relationship distress among same‐gender couples. However, many of these programs are conducted in metropolitan areas and lack the ability to reach rural populations. The current study sought to investigate whether two wide‐reaching web‐based heteronormative relationship education programs could positively impact same‐gender relationships. In a sample of 49 same‐gender couples, heteronormative relationship education had small (Cohen's d = 0.16–0.39) but reliably positive effects on key areas of relationship functioning and perceived stress relative to a waitlist control group. Additionally, when same‐gender couples were matched with different‐gender individuals with similar baseline characteristics, no reliable differences between the two groups emerged even though the program effects were sometimes half as large for same‐gender couples. Finally, same‐gender participants were as satisfied with the program as the matched different‐gender individuals. Though the results of the present study indicate that heteronormative relationship education can be helpful for same‐gender couples, additional tailoring should be undertaken to ensure that same‐gender couples experience as much benefit as possible. Estimates from the current study could be used in future studies to detect what might be small‐sized differences.     

The utilitarian core hypothesis: cases for testing the stability of languages in the wake of conquest

Based on the "utilitarian core hypothesis" that the most common words of a language develop early and resist change, the current exploratory study examined three test cases to suggest what happens to the common core of a language when its speakers are conquered. Whissell (1998) raised this issue by implication through demonstrating that the common core of English is largely Anglo-Saxon and thus survived the Norman Conquest. The notion that unique merits of English accounted for its success has a long history dating at least to Verstegan (1605/1976). We suggested that there are also instances of conquest in history illustrating the persistence of other languages despite the political subjugation of their speakers. Test cases included, in addition to the Norman Conquest of England, the Arab-Berber Conquest of most of the Iberian Peninsula, and Russian domination of modern Uzbekistan. The combined results suggest that persistence of a utilitarian core despite conquest is not an isolated instance. As a phenomenon it offers a more parsimonious account than do appeals to the special merits of English, Spanish, or Modern Uzbek. We have integrated these findings within a psychological framework pertaining to language use and change.     

The Processing of Grammatical Gender and Number in Spanish

The aim of the present study is to explore the representation and processing of inflectional morphology in Spanish. Experiment 1 compared the access time for words from the same base morpheme contrasted by the surface frequency of the masculine and feminine form, i.e., masculine-dominant items and feminine-dominant items. The results showed a surface frequency effect in both types of items. Experiment 2 compared the access time for masculine words having the same surface frequency but differing in their summed frequency (masculine plus feminine forms), the results showing no significant effect of this parameter. Finally, experiment 3 compared the access time for words from the same stem and contrasting by the surface frequencies for the singular and plural forms, i.e., singular-dominant and plural-dominant words. A clear frequency effect was observed for the singular-dominant words but not for plural-dominant ones. These results suggest that gender information is stored in the corresponding lexical entry and accessed from the full word form whereas the information about number is accessed from the stem corresponding to the singular form.     

Racial differences in birth outcomes: the role of general, pregnancy, and racism stress.

OBJECTIVE: This study examined the role of psychosocial stress in racial differences in birth outcomes. DESIGN: Maternal health, sociodemographic factors, and 3 forms of stress (general stress, pregnancy stress, and perceived racism) were assessed prospectively in a sample of 51 African American and 73 non-Hispanic White pregnant women. MAIN OUTCOME MEASURES: The outcomes of interest were birth weight and gestational age at delivery. Only predictive models of birth weight were tested as the groups did not differ significantly in gestational age. RESULTS: Perceived racism and indicators of general stress were correlated with birth weight and tested in regression analyses. In the sample as a whole, lifetime and childhood indicators of perceived racism predicted birth weight and attenuated racial differences, independent of medical and sociodemographic control variables. Models within each race group showed that perceived racism was a significant predictor of birth weight in African Americans, but not in non-Hispanic Whites. CONCLUSIONS: These findings provide further evidence that racism may play an important role in birth outcome disparities, and they are among the first to indicate the significance of psychosocial factors that occur early in the life course for these specific health outcomes.     

Parental Bonding and Its Effect on Adolescent Substance Use and Sexual Debut

The purpose of this study was to examine associations among parental bonding factors and the early onset of sexual behaviors and substance use. Significant differences were found in the levels of care among the parental status groups and among the ages of onset for alcohol use.     

Does Reducing Male Domination in Teams Attenuate or Intensify the Harmful Effects of Perceived Discrimination on Women's Job Satisfaction? A Test of Competing Hypotheses

This study tested competing theoretical predictions surrounding the moderating effect of male domination in teams on the relation between women's perceptions of gender discrimination and their job satisfaction. Using archival data from an all-female sample of active military personnel (n = 3,015) comprising 321 work teams, which fell on a continuum from less male dominated to more male dominated, we found that the extent to which teams were male dominated moderated the negative link between perceived gender discrimination and job satisfaction, such that perceptions of discrimination were more negatively related to job satisfaction for women working in teams that were less male dominated than for those working in teams that were more male-dominated. We conclude by discussing the implications of our findings for research and practice and highlight several avenues for future research.
