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.     

Crossing the pillars of Hercules: the role of spatial frames of reference in error making

This paper introduces a perspective accounting for errors that may occur as a result of the human interaction with the three-dimensional (3D) space. Particularly, we are interested in errors that are caused by cognitively crossing the boundary between peripersonal and extrapersonal space. Several behavioural, neurophysiological, and neuropsychological perspectives are reviewed in order to develop the theoretical framework on which our ideas are founded. We argue that cognitively crossing the boundary implies switching from one frame of reference to another, which, as a consequence, implies specific costs. The results of five experiments (overall involving 76 participants) support our hypothesis, suggesting the existence of different action-oriented spatial frames of reference.     

The Structure of Predication

The paper discusses the structure of non-verbal predication, with particular reference to the role of the copula. Differently from the main tenets of contemporary logico-philosophical and linguistic theories, a model of predication is proposed where the verbal component (specifically, tense information) is regarded as central in establishing the syntactic and semantic relation between a predicate and its subject. It is thus possible to recover some of the insights of the pre-Fregean analysis of predication. The proposed solution has a number of significant consequences for the structure to be assigned to non-verbal predication, in particular for the semantics of small clause constituents, where the predication is established without the copula.     

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.     

Fathers' caregiving in low-income African–American and Hispanic–American families

The present study assessed fathers' and mothers' relative involvement in infant caregiving tasks in 34 low-income African–American and Hispanic–American families. Analysis showed that involvement in childcare differed as a function of the gender of the parent. Fathers spent one half the time mothers did in caregiving. However, fathers' and mothers' participation in caregiving did not vary as a function of ethnic group. African–American parents reported to have received more family support than Hispanic–American parents. Although relationships were noted between age, income, education, length of marriage, social support, and involvement in infant caregiving, these sociodemographic variables did not predict parents' participation in childcare. The results are discussed in relation to the preconceived notion that low-income, minority fathers are ‘uninvolved’. ©1997 John Wiley & Sons, Ltd.     

Less exploring by mouth occurs in newborns of depressed mothers

Twenty‐four newborns (M age = 12 days) of depressed and nondepressed mothers were assessed for oral perception of a nubby and smooth texture. Both groups of newborns discriminated between these textures and showed a sucking preference for the smooth texture. However, the newborns of depressed mothers spent 50% less time orally exploring the stimuli, one‐third less time exploring the more novel nubby texture, and 59% less time mouthing the smooth texture. Newborns of depressed mothers may have biological differences that affect their emotional arousal and emotional regulation (e.g., capacity for self‐soothing). © 2000 Michigan Association for Infant Mental Health.
