Error detection and error memory in spatial navigation as reflected by electrodermal activity

The study investigated spatial navigation by means of electrodermal activity (EDA). Two groups of healthy subjects (group 1, age <38; group 2, age ≥38) were recorded during navigation through two 3-D virtual mazes differing in difficulty, that is, Maze Simple (MazeS) and Maze Complex (MazeC). Our results show (1) an effect of difficulty, that is, larger skin conductance responses (SCRs) and slower velocity profiles while navigating through MazeC as compared to MazeS. (2) An effect of age, that is, larger SCRs and faster velocity profiles in younger subjects (group 1) compared to older subjects (group 2). (3) An effect of maze region, that is, SCRs increased when subjects entered dead ends with group 1 (young group) decreasing in velocity, whereas group 2 (old group) increased in velocity. (4) And an error memory effect, that is, subjects who remembered an error at a given decision point (crossroads preceding dead ends in MazeC) from previous trials, and then if they did not repeat that error, elicited decreased SCRs as compared to subjects who did not remember and subsequently repeated an error. The latter aspect is the most impactful as it shows that EDA is able to reflect error detection and memory during spatial navigation. Our data designate EDA as suitable monitoring tool for identification and differentiation of the affective correlates underlying spatial navigation, which has recently attracted researchers’ attention due to its increased use in 3-D virtual environments.     

The impact of uncertainty and communal coping on mental health following natural disasters

Abstract

Feelings of uncertainty are a central feature of the disaster experience. Surprisingly, though, there is very little systematic quantitative research about the impact of uncertainty on disaster survivors. Moreover, communal coping has increasingly received attention as a potential buffer of the negative effects of stressors but that literature is also limited in its application to disasters. This investigation applies research in the domain of uncertainty, together with the Theoretical Model of Communal Coping to better understand the experience of a community exposed to three wildfires in a one year period. A random-digit dialing procedure was used to gather data from 402 individuals. Participants completed measures of mental health, uncertainty, and communal coping in the context of their experience with the most personally stressful of the three wildfires. All analyses were examined separately for those who were evacuated and those who were not. Results support the negative impact of uncertainty across both evacuated and nonevacuated sub-samples and show a strong buffering role for communal coping among those who evacuated. The implications of these findings for the understanding of wildfire survivors' experiences are noted and future directions are proposed.

Brain Fag: A Case Study Showing the Diagnosis and Therapy in Nigeria

The co-occurrence of somatic complaints along with other forms of mental illness such as depression, anxiety and brain fag is well documented in mental health literature. In Africa, the notion that somatic complaints are a variant of depression is popular. However objective empirical efforts to prove this notion are inconclusive. The common co-occurrence of somatic complaints along with depression, anxiety and brain fag complaints in Nigeria may put clinicians in a dilemma in making diagnostic and therapeutic decisions for their clients. In this paper the authors applied the Harmony Restoration Therapy (HRT) in the management of somatic, depressive, anxiety and brain fag symptoms of a client. The HRT is a psychotherapeutic framework based on the Africa world view of health and illness where health is harmony and illness is disharmony in one’s world of relationships. The case was used to illustrate the co-morbidity of depression, anxiety, somatization and Brain Fag and tries to contribute to how Brain Fag can be treated.

When forewarning backfires: Paradoxical effects of elaborating social feedback on entrapment in a losing course of action

Entrapment occurs if people persist with losing courses of action. In two experiments, we show how elaborating social feedback (i.e., premature praise or forewarning regarding the chosen course of action) can have paradoxical effects on entrapment. The participants acted as head of a translation department and had to choose one out of four possible translation strategies for their employees. After choosing, they read four arguments (presumably written by former participants) which were either all in favor of the strategy chosen, all against it, or mixed. Half of the participants only read these arguments, whereas the other half elaborated on them by providing written comments (Experiment 1). The results showed that elaborating on other persons' arguments led to stronger entrapment, independently of whether the arguments were positive or negative. This pattern was due to biased argument processing: Whereas confirming thoughts were generated for positive arguments, negative arguments were refuted. Experiment 2 confirmed that this biased argument processing caused subsequent entrapment. These results indicate that elaborating any type of argument can lead to heightened entrapment and, hence, forewarning can backfire. Copyright © 2009 John Wiley & Sons, Ltd.     

Gender Stereotypes in Portuguese Television Advertisements

This study examined the portrayal of men andwomen in a sample of Portuguese television commercials,attempting to replicate and extend past investigationsdone in America, Australia, Britain, and Italy. The aim was to update Portuguese research andto compare findings across cultures. Three hundred andfour evening commercials were content analyzed by tworaters, one male and the other female, to check reliability. The attributes of each of theircentral figures were classified into 11 categories:gender, mode of presentation, credibility, role,location, age, argument, reward type, product type,background, and end comment. Strong evidence of differencesin the presentation of male and female characteristicswas obtained. The implications of results for thedevelopment and maintenance of gender roles arediscussed.
