Sex stereotypes and implicit personality theory. II. A trait-inference approach to the assessment of sex stereotypes

Two experiments were conducted to assess sex stereotypes using the trait-inference method originated by Asch (1946). In both, subjects were asked to make inferences about the personality of a male or a female stimulus target who was introduced by a brief list of traits. In Experiment 1 this trait list described the target as either good or bad in intellectual activities and as either warm or cold while in Experiment 2 the introductory list comprised traits which are relatively neutral in terms of evaluation. Subjects rated the stimulus persons on adjective scales selected to reflect dimensions of personality perception reported in previous research. In both studies, male targets were rated significantly higher than females in terms of the Intellectual Desirability dimension. In addition, female targets tended to be rated higher on Communion in Experiment 1 (p<.06), and lower than males on Potency in Experiment 2 (p<.07). No differences as a function of stimulus sex were obtained for Social Desirability, Activity, and Agency. The results suggest that the dimension of implicit personality theory most closely associated with perceived sex differences is a combination of Intellectual Desirability and Potency. The male end of this dimension is relatively well defined by traits which convey a hard-headed, rational approach to problem solving. The female end is much less elaborated and consists of traits reflecting soft-heartedness.     

Communication of Genetic Risk Information to Daughters in Families with Fragile X Syndrome: The Parent’s Perspective

Parental approaches to communicating information about genetic disorders to their children may be an important determinant in how the children manage stress as well as their adjustment and adaptation to that information. We explored communication patterns through structured interviews with 46 parents of daughters who learned about their genetic risk status as minors. Three different levels of knowledge about fragile X syndrome were explored: 1) informing that it has been diagnosed in the family and is an inherited disorder, 2) informing about the possibility of a daughter being a carrier, and 3) if testing had been done, informing the daughter of her actual carrier status. Additionally, parental perceptions of their daughter’s understanding of the information were explored along with frequency of discussions. We found that communication about genetic risk was initiated by the parents. Five disclosure patterns were identified with variations in style, content, and frequency of communication related to the information that was being disclosed. Aspects of resilient communication were present for all levels of disclosure; however, as the information became more personally relevant for the daughter such as disclosure about the possibility of “being a carrier” for fragile X syndrome and there was uncertainty regarding potential outcomes, the conversations included fewer resilient characteristics. Uncertainty about what and how to present information may negatively affect a parent’s ability to include elements of resilient communication when disclosing genetic risk information.     

Prevalence and associated factors with body image dissatisfaction among adults in southern Brazil: A population-based study

We investigated the prevalence of body image dissatisfaction (BID) and associated factors in Florianopolis, Brazil. BID was analyzed in a sample (N = 1720) of adults through the Figure Rating Scale. The independent variables were sociodemographic factors, health behaviors, and morbidities. A multinomial logistic regression analysis was used. More men (14.2%) than women (6.1%) presented BID by being lighter than ideal (LI). Conversely, more women (66.6%) than men (46.3%) showed BID by being heavier than ideal (HI). BID by being HI was higher among older women, those with high BMI and those with a partner. In men, lower BMI and the presence of common mental disorders were associated with BID due to being LI. Advanced ages, alcohol abuse, physical inactivity, and obesity were associated with BID due to being HI. We must consider different public health interventions for men and women to reduce BID in Brazilian adults.     

Localizing complex neural circuits with MEG data

During cognitive processing, the various cortical areas, with specialized functions, supply for different tasks. In most cases then, the information flows are processed in a parallel way by brain networks which work together integrating the single performances for a common goal. Such a step is generally performed at higher processing levels in the associative areas. The frequency range at which neuronal pools oscillate is generally wider than the one which is detectable by bold changes in fMRI studies. A high time resolution technique like magnetoencephalography or electroencephalography is therefore required as well as new data processing algorithms for detecting different coherent brain areas cooperating for one cognitive task. Our experiments show that no algorithm for the inverse problem solution is immune from bias. We propose therefore, as a possible solution, our software LOCANTO (LOcalization and Coherence ANalysis TOol). This new package features a set of tools for the detection of coherent areas. For such a task, as a default, it employs the algorithm with best performances for the neural landscape to be detected. If the neural landscape under attention involves more than two interacting areas the SLoreta algorithm is used. Our study shows in fact that SLoreta performance is not biased when the correlation among multiple sources is high. On the other hand, the Beamforming algorithm is more precise than SLoreta at localizing single or double sources but it gets a relevant localization bias when the sources are more than three and are highly correlated.     

A glass rodent enclosure: Gerbil City

A glass housing unit for the study of rodent burrowing behavior is described. The results of 18 months of burrowing for a family ofMeriones unguiculatus are depicted. The system can be used to investigate relationships among the animals’ behaviors, communication processes, and ecology.     

The Effects of Names on Perception of Intelligence, Popularity, and Competence

Three experiments were conducted to explore the effects of first names on judgments of intelligence, popularity, and competence. In Experiment 1, first names that were used more often in the past than they are now (called Older Generation names) were rated by a sample of college-aged judges as less popular and less intelligent than were first names that are used more often now than in the past (called Younger Generation names). In addition, male first names tended to have higher ratings of these same qualities than did female first names. In Experiments 2 and 3, either resumes or personal ads were used to provide additional information to the raters. Results similar to those found in Experiment 1 were obtained. In general the present experiment used groups of names rather than individual names so as to control for possible irrelevant and idiosyncratic differences that might be found among individual names. Relevance to research in which men and women are compared was discussed.
