The use of virtual reality in the study, assessment, and treatment of body image in eating disorders and nonclinical samples: a review of the literature

This article reviews research into the use of virtual reality in the study, assessment, and treatment of body image disturbances in eating disorders and nonclinical samples. During the last decade, virtual reality has emerged as a technology that is especially suitable not only for the assessment of body image disturbances but also for its treatment. Indeed, several virtual environment-based software systems have been developed for this purpose. Furthermore, virtual reality seems to be a good alternative to guided imagery and in vivo exposure, and is therefore very useful for studies that require exposure to life-like situations but which are difficult to conduct in the real world. Nevertheless, review highlights the lack of published controlled studies and the presence of methodological drawbacks that should be considered in future studies. This article also discusses the implications of the results obtained and proposes directions for future research.     

How modality specific is the iambic-trochaic law? Evidence from vision

The iambic-trochaic law has been proposed to account for the grouping of auditory stimuli: Sequences of sounds that differ only in duration are grouped as iambs (i.e., the most prominent element marks the end of a sequence of sounds), and sequences that differ only in pitch or intensity are grouped as trochees (i.e., the most prominent element marks the beginning of a sequence). In 3 experiments, comprising a familiarization and a test phase, we investigated whether a similar grouping principle is also present in the visual modality. During familiarization, sequences of visual stimuli were repeatedly presented to participants, who were asked to memorize their order of presentation. In the test phase, participants were better at remembering fragments of the familiarization sequences that were consistent with the iambic-trochaic law. Thus, they were better at remembering fragments that had the element with longer duration in final position (iambs) and fragments that had the element with either higher temporal frequency or higher intensity in initial position (trochees), as compared with fragments that were inconsistent with the iambic-trochaic law or that never occurred during familiarization.     

Short-term memory performances during sustained wakefulness in patients with obstructive sleep apnea-hypopnea syndrome

Both working and immediate memories were assessed every 4h by specific short-term memory tasks over sustained wakefulness in 12 patients with obstructive sleep apnea and hypopnea syndrome (OSAHS) and 10 healthy controls. Results indicated that OSAHS patients exhibited lower working memory performances than controls on both backward digit span and complex Sternberg tasks. Speed and accuracy on Sternberg tasks were affected by memory load in both groups. However, immediate memory was not impaired in OSAHS patients. Diurnal and nocturnal SaO(2) were correlated with speed and accuracy high-speed memory scanning performance on Sternberg tasks in patients. These results suggest specific working memory deficits associated with OSAHS over sustained wakefulness with a possible deficiency in the central executive responsible for the higher information processing, in addition to a potentially insufficient storage capacity. Among OSAHS patients, working memory ability involved in high-speed memory scanning may be impaired by chronic hypoxemia.     

Factor structure of the Spanish adaptation of Tarrant's Group Identification Scale

In this study, the factor structure of the Spanish version of Tarrant's Group Identification Scale is analyzed. This scale is based on the social identity theory and measures cognitive, evaluative, and affective aspects of group identification. Although this scale has been considered unidimensionally with adolescents, it is based on previous group identification scales considered multidimensionally. From confirmatory analysis, some factor models were tested in two independent samples of adolescents: Spanish (N= 1,795) and Mexican (N= 1,494). The three-factor model (self-categorization, group evaluation, and commitment to the group) produced the best fit in both samples. Results are compatible with the multidimensional structure hypothesis of group identification.     

Family Gender Role and Guilt in Spanish Dual-Earner Families

In dual-earner families the balance between work and family demands facilitates the development of guilt feelings when parents perceive a non-fulfillment of their responsibilities in childcare. Specifically, women who aspire to personal and professional development on the basis of more egalitarian gender role models must deal with the traditional stereotypes that maintain an intensive maternity mandate that prioritizes the family. On the other hand, for men the role change is primarily in the family setting with the development of a new father role more involved in the care of their children, which is not easily compatible with the more traditional breadwinner role. This study explored the feelings of guilt about parenting in 251 employed Spanish parents with children between 3 and 6 years of age, through the Scale of Guilt Feelings about Parenting, and its relationship with traditional stereotypes of maternal and family role. The scale addresses diverse situations pertaining to child rearing in which work requirements do not allow parents full availability for the care of their children. This availability is present in the model of intensive maternity and in the new father role model. Results indicate the presence of similar and high levels of guilt in fathers and mothers, although in men guilt is related to a non-traditional family role ideology, whereas in women guilt is related to a more traditional maternal role stereotype.     

A Woman’s Place and a Man’s Duty: How Gender Role Incongruence in One’s Family Life Can Result in Home-Related Spillover Discrimination at Work

The purpose of this study was to investigate how gender role incongruence in terms of women being primary wage earners and males being secondary wage earners in their families could affect them at work. Using an experimental design and a sample of 306 college students, I explored how females who are the primary wage earners in their families and males who are the secondary wage earners are perceived and evaluated in a work setting. I proposed, and found, that female primary wage earners are seen as the least overqualified and are given lower reward recommendations than equally qualified male peers (i.e., peers with exactly the same credentials and job performance). Male secondary wage earners are seen as being the most overqualified and are given higher reward recommendations than equally qualified female peers. Results demonstrate how the lack of fit model, which has been shown to penalize women who succeed in traditionally masculine domains (Dipboye, Acad Manag Rev 10:16–127, 1985; Heilman, Res Organ Behav 5:269–298, 1983, J Soc Issues 57:657–674, 2001), can be applied to situations where gender-incongruent behavior exists in the form of women being primary wage earners in their families. I refer to this phenomenon as “home-related spillover discrimination,” named after the spillover effects that derive from societal expectations that are transferred into employment situations (Nieva and Gutek, Acad Manag Rev 5:267–276, 1980). The practical implication of this finding is that this may present a new form of sex discrimination against women that has not yet been considered. This is the first study to show how violating stereotypical roles in terms of family wage earner status can influence outcomes in work settings.     

The Jekyll and Hyde of emotional intelligence: emotion-regulation knowledge facilitates both prosocial and interpersonally deviant behavior

Does emotional intelligence promote behavior that strictly benefits the greater good, or can it also advance interpersonal deviance? In the investigation reported here, we tested the possibility that a core facet of emotional intelligence--emotion-regulation knowledge--can promote both prosocial and interpersonally deviant behavior. Drawing from research on how the effective regulation of emotion promotes goal achievement, we predicted that emotion-regulation knowledge would strengthen the effects of other-oriented and self-oriented personality traits on prosocial behavior and interpersonal deviance, respectively. Two studies supported our predictions. Among individuals with higher emotion-regulation knowledge, moral identity exhibited a stronger positive association with prosocial behavior in a social dilemma (Study 1), and Machiavellianism exhibited a stronger positive association with interpersonal deviance in the workplace (Study 2). Thus, emotion-regulation knowledge has a positive side and a dark side.     

Psychometric update of the Social Anxiety Screening Scale (SASS/EDAS) in a Spanish adolescent population

The aim of this work was to update the validation of the Social Anxiety Screening Scale (SASS/EDAS) in a sample of Spanish adolescents. To achieve this, one study with a sample of 1489 students in secondary education, of ages 14 to 17 years, were carried out. The psychometric properties of EDAS were examined through confirmatory factor analysis, reliability (Cronbach's alpha), temporal stability (test-retest), and concurrent criterion validity. The results supported the three-independent-factor structure (avoidance, distress and interference), that showed best fit indices compared to alternative models. They also showed that the scores of participants on EDAS scales were reliable in terms of internal consistency (alpha > .80) and moderately reliable concerning temporal stability (r = .48-.60) over a five-week period. The correlations between the EDAS factors and other social anxiety measures were positive and significant. Data provide empirical evidence of the estimation of reliability and validity of this scale. Future work should extend the validation of the EDAS in clinical samples.     

The use of the effect size in JCR Spanish journals of psychology: from theory to fact

In 1999, Wilkinson and the Task Force on Statistical Inference published "Statistical Methods and Psychology: Guidelines and Explanation." The authors made several recommendations about how to improve the quality of Psychology research papers. One of these was to report some effect-size index in the results of the research. In 2001, the fifth edition of the Publication Manual of the American Psychological Association included this recommendation. In Spain, in 2003, scientific journals like Psicothema or the International Journal of Clinical and Health Psychology (IJCHP) published editorials and papers expressing the need to calculate the effect size in the research papers. The aim of this study is to determine whether the papers published from 2003 to 2008 in the four Spanish journals indexed in the Journal Citation Reports have reported some effect-size index of their results. The findings indicate that, in general, the followup of the norm has been scanty, though the evolution over the analyzed period is different depending on the journal.
