Modulating effects in learned helplessness of dyadic dominance-submission relations

In this experiment, learned helplessness was studied from an ethological perspective by examining individual differences in social dominance and its influence on the effects of helplessness. Ninety animals were used, 30 randomly selected and 60 selected because of their clear dominance or submission. Each condition (dominant, submissive, and random) was distributed in three subgroups corresponding to the triadic design. The test consisted of an escape/avoidance task. The results showed that the animals in the uncontrollable condition performed worse than those in the controllable and no treatment conditions. Social submission and dominance reduced vulnerability of the subjects against learned helplessness. Submission had a facilitating effect on subsequent learning, independently of whether pretreatment was controllability or uncontrollability. Learned mastery was observed in the submissive condition, because submission benefited the subjects in the controllable condition in comparison with the untreated subjects, and dominance impaired the subjects in the controllable condition.     

The role of attention in the occurrence of the affordance effect

It has been demonstrated that visual objects activate responses spatially corresponding to the orientation (left or right) of their graspable parts. To investigate the role of attention orienting in the generation of this effect, which we will refer to as affordance effect, we ran three experiments in which the target stimulus could either correspond or not with a dynamic event capturing attention. Participants were required to press a left or right key according to the vertical orientation (upward or inverted) of objects presented with their handles oriented to the right or to the left. In Experiments 1 and 2, the objects were located above or below fixation, while in Experiment 3, to assess the contemporary presence of the affordance and Simon effects, the objects were located to the left or right of fixation. The results showed that while the affordance effect, when evident, was always relative to the target object, irrespective of its attentional capturing properties, the Simon effect occurred relative to the event capturing attention. These findings suggest that automatic and controlled processes of visual attention may play a differential role in the occurrence of the two effects.     

Mediating relationship between body mass index and the direct measures of the Theory of Planned Behaviour on physical activity intention

This research examines (a) the interrelationships between body mass index (BMI), the direct measures of the Theory of Planned Behaviour (TPB) and physical activity intention and (b) the potential mediation effects of the direct measures of the TPB in the relationship between BMI and physical activity intention in a sample of Australian adults. A total sample of 1,062 respondents participated in a computer-assisted telephone-interview (CATI) survey comprised of a standardised introduction; questions regarding TPB and physical activity; and standard demographic questions. BMI for each participant was calculated from self-reported height and weight. Separate regression analyses were performed to examine the mediating effects of each of the direct measures of the TPB on the predictive relationship between the BMI and physical activity intention, as proposed by Baron and Kenny (Journal of Personality and Social Psychology, 51(6), 1173 - 1182, 1986). Findings indicated that the direct measure of attitude and perceived behavioural control mediated the relationship between BMI and physical activity intention. However, the direct measure of subjective norm failed to act as a mediating mechanism. To date there has been no research that has examined the mechanism by which body mass may affect physical activity behaviour. Given the current focus for health promotion specialists on promoting physical activity as a strategy for reducing overweight and obesity, a theoretical understanding of weight-related barriers to physical activity may aid in the development of future interventions and community physical activity programs, particularly those targeting overweight and obese populations.     

Future Thinking in Young Children

ABSTRACT— The study of future thinking is gaining momentum across various domains of psychology. Mentally projecting the self forward in time (i.e., mental time travel) is argued to be uniquely human and of vital importance to the evolution of human culture. Yet it is only recently that developmentalists have begun to study when, and how, this capacity emerges. I begin by outlining the concept of mental time travel, along with newly developed methodologies to test children's ability to mentally project the self into the future. Data suggest that this ability is in place by ages 4 or 5 but also reveal conditions under which children may experience difficulty accurately predicting their future desires. I conclude by discussing how the research on children's mental time travel can be used to further our understanding of the development of future-oriented behaviors, including planning and delaying gratification.     

Weight Halo Effects: Individual Differences in Perceived Life Success as a Function of Women's Race and Weight

The question of whether or not life success halo effects occur for weight for Black and White women was examined in an experiment using a 2 (race of woman) × 2 (weight of woman) × 2 (sex of participant) design and measures of perceived life success, attractiveness, and personality. The thinner White woman was expected to receive higher life success, attractiveness, and personality ratings than the heavy White woman. However, the heavy Black woman was expected to receive higher ratings than the thinner Black woman. The results were consistent with expectations. These results are discussed in terms of prior research on beauty, weight, and stereotyping.     

A database for semantic, grammatical, and frequency properties of the first words acquired by Italian children.

The CFVlexvar.xls database includes imageability, frequency, and grammatical properties of the first words acquired by Italian children. For each of 519 words that are known by children 18-30 months of age (taken from Caselli & Casadio's, 1995, Italian version of the MacArthur Communicative Development Inventory), new values of imageability are provided and values for age of acquisition, child written frequency, and adult written and spoken frequency are included. In this article, correlations among the variables are discussed and the words are grouped into grammatical categories. The results show that words acquired early have imageable referents, are frequently used in the texts read and written by elementary school children, and are frequent in adult written and spoken language. Nouns are acquired earlier and are more imageable than both verbs and adjectives. The composition in grammatical categories of the child's first vocabulary reflects the composition of adult vocabulary. The full set of these norms can be downloaded from www.psychonomic.org/archive/.

Patterns of Parental Rearing Styles and Child Behaviour Problems among Portuguese School-Aged Children

The majority of studies investigating the effects of parental behaviour on the child’s adjustment have a dimensional approach. We identified the existence of various patterns in parental rearing styles and analysed the relationship between different parenting patterns and behavioural problems in a group of school-aged children. A longitudinal, multi-informant study was conducted. The sample consisted of 519 school-aged children from the Portuguese general population. Parental rearing styles were measured using the EMBU-C, a questionnaire that evaluates children’s perception of parental rearing dimensions. The assessment of child behavioural problems included the evaluation of internalizing and externalizing problems, and data from multiple reporters (parents and teacher). One year later, after a school transition, the adjustment of a sub-sample of 220 children was evaluated again. Cluster analysis identified four types of parental rearing styles: low support, supportive-controller, rejecting-controller, and supportive. In both assessment periods, low support and rejecting-controller parenting patterns showed higher levels of behavioural problems than the supportive and supportive-controller parenting patterns. These patterns show significant differences between them regarding behavioural problems and have a higher predictive value regarding externalizing problems (versus internalizing problems).     

Perceived political self‐efficacy: Theory,assessment, and applications

Political efficacy is addressed within the framework of social cognitive theory and a new measure to assess perceived political self‐efficacy is presented. Three studies document the validity of the new scale of measurement. The first study (N = 1673) examined the psychometric properties of the scale in accordance with classical test theory. This led to the identification of a unidimensional factor structure, including perceived political self‐efficacy in promoting one's own political opinion, in sustaining the political programs of the party to which one belongs, and in monitoring one's own political representatives' commitment. The second study (N = 632) further confirmed the internal and construct validity of the scale; criterion validity was also investigated using several indicators of political interest and participation. The third study (N = 1176) showed that politicians holding offices have higher levels of perceived political self‐efficacy than partisans and voters, further corroborating the criterion validity of the scale.
