Searching for inhibition of return in the rat using the covert orienting of attention task

Inhibition of return (IOR) is an important psychological construct describing inhibited responses to previously attended locations. In humans, it is investigated using Posner’s cueing paradigm. This paradigm requires central visual fixation and detection of cued stimuli to the left or right of the fixation point. Stimuli can be validly or invalidly cued, appearing in the same or opposite location to the cue. Although a rat version of the spatial cueing paradigm (the covert orienting of attention task) does exist, IOR has so far not been demonstrated. We therefore investigated whether IOR could be robustly demonstrated in adult male rats using the covert orienting of attention task. This task is conducted in holed wall operant chambers with the central three holes mimicking the set-up for Posner cueing. Across four samples of rats (overall n = 84), we manipulated the following task parameters: stimulus onset asynchronies (Experiments 1–3), cue brightness (Experiment 1b) and the presence of a central reorienting event (Experiment 4). In Experiment 1, we also investigated strain differences by comparing Lister Hooded rats to Sprague–Dawley rats. Although Lister Hooded rats briefly showed evidence of IOR (Experiment 1a, and see Online Resource 1 data), we were unable to replicate this finding in our other experiments using different samples of this strain. Taken together, our findings suggest that IOR cannot be robustly demonstrated in the rat using the covert orienting of attention task conducted in holed wall operant chambers.     

German Muslims and the ‘Integration Debate’: Negotiating Identities in the Face of Discrimination

Based on five focus groups (total N?=?56) with German Muslims, we analyze discourses on the experience of discrimination and feelings of national and religious attachment. The focus groups took place in mid to late 2010 in four German cities. Whereas only few participants describe personal discrimination by non-Muslim Germans, almost all participants complain about being collectively discriminated and rejected. This perception triggers processes of confirming their original cultural identity, primarily their Muslim affiliation and of strengthening the boundary towards the wider society. The analysis of the discourse shows the participants to fall back into an essentialized way of thinking that makes their ethnic being incompatible with being German; and they resort to their Muslim roots as a cultural resource for identity construction and self-worth. Others cope with their feeling of rejection by engaging in local politics and sports activities that allows them to attribute themselves a hyphenated identity as Turkish-Germans. The findings are discussed in terms of social identity, psychological essentialism, transnationalized religion, and boundary making.     

Attentional asymmetries in a visual orienting task are related to temperament

Spatial asymmetries are an intriguing feature of directed attention. Recent observations indicate an influence of temperament upon the direction of these asymmetries. It is unknown whether this influence generalises to visual orienting behaviour. The aim of the current study was therefore to explore the relationship between temperament and measures of spatial orienting as a function of target hemifield. An exogenous cueing task was administered to 92 healthy participants. Temperament was assessed using Carver and White's (1994) Behavioural Inhibition System and Behavioural Activation System (BIS/BAS) scales. Individuals with high sensitivity to punishment and low sensitivity to reward showed a leftward asymmetry of directed attention when there was no informative spatial cue provided. This asymmetry was not present when targets were preceded by spatial cues that were either valid or invalid. The findings support the notion that individual variations in temperament influence spatial asymmetries in visual orienting, but only when lateral targets are preceded by a non-directional (neutral) cue. The results are discussed in terms of hemispheric asymmetries and dopamine activity.     

An investigation of salespeople’s nonverbal behaviors and their effect on charismatic appearance and favorable consumer responses

The concept of charisma has gained considerable interest among social scientists in multiple disciplines. Nevertheless, research on charisma in the marketing field is scarce, and little is known about which specific nonverbal behaviors predict perceived charisma and lead to positive consumer responses. Therefore, the aim of this article is to identify nonverbal behaviors that lead to a salesperson’s perceived charisma in a personal selling context by means of high-precision, time-locked coding. This research explores aspects of body language that differentiate salespeople from each other and investigates whether such differences are antecedents of perceived charisma. The findings indicate that certain arm actions, arm postures, and action functions have a significant effect on charismatic appearance and can in turn produce favorable attitudes toward the salesperson.     

Youth as Partners, Participants or Passive Recipients: A Review of Children and Adolescents in Community-Based Participatory Research (CBPR)

Community-based participatory research (CBPR) is an orientation to research that places value on equitable collaborations between community members and academic partners, reflecting shared decision making throughout the research process. Although CBPR has become increasingly popular for research with adults, youth are less likely to be included as partners. In our review of the literature, we identified 399 articles described by author or MeSH keyword as CBPR related to youth. We analyzed each study to determine youth engagement. Not including misclassified articles, 27 % of percent of studies were community-placed but lacked a community partnership and/or participatory component. Only 56 (15 %) partnered with youth in some phase of the research process. Although youth were most commonly involved in identifying research questions/priorities and in designing/conducting research, most youth-partnered projects included children or adolescents in several phases of the research process. We outline content, methodology, phases of youth partnership, and age of participating youth in each CBPR with youth project, provide exemplars of CBPR with youth, and discuss the state of the youth-partnered research literature.     

Exhibitionistic Human Movement Responses of Strippers: An Attempt to Validate the Rorschach M

A group of women employed as strippers produced significantly more exhibitionistic M on the Rorschach than three other matched control groups. Results were interpreted as supporting the position that the human movement response is related to actual behavioral tendencies.
