Self-awareness,Perspective-taking,and Egocentrism

The present experiment examined the effect of self-awareness on adult perspective-taking and egocentrism. After having indicated their own opinion on an ecology-related topic, university students estimated a fellow student’s opinion on the same matter. Participants did so either in front of a mirror or not, and either after having received a cue for the fellow student’s most probable opinion—his perspective—or not, resulting in a 2 (self-awareness: Low vs. high) × 2 (cue: Yes vs. no) between persons design. As expected, self-aware participants were more likely to correctly estimate the fellow student’s most probable opinion, reflecting perspective-taking, if a cue for his/her perspective was provided. Moreover, self-awareness also reduced participants’ false consensus beliefs (i.e., egocentrism)—when they had a cue for the fellow student’s perspective. The results conceptually replicate and extend previous findings on self-awareness, perspective-taking, and egocentrism.     

Basic psychological needs and neurophysiological responsiveness to decisional conflict: an event-related potential study of integrative self processes

Fulfillment of the basic psychological needs for competence, relatedness, and autonomy is believed to facilitate people’s integrative tendencies to process psychological conflicts and develop a coherent sense of self. The present study therefore used event-related potentials (ERPs) to examine the relation between need fulfillment and the amplitude of conflict negativity (CN), a neurophysiological measure of conflict during personal decision making. Participants completed a decision-making task in which they made a series of forced choices according to their personal preferences. Three types of decision-making situations were created on the basis of participants’ unique preference ratings, which were obtained prior to ERP recording: low-conflict situations (choosing between an attractive and an unattractive option), high-conflict approach-approach situations (choosing between two similarly attractive options), and high-conflict avoidance-avoidance situations (choosing between two similarly unattractive options). As expected, CN amplitudes were larger in high- relative to low-conflict situations, and source localization analyses suggested that the anterior cingulate cortex was the generating structure of the CN. Most importantly, people reporting higher need fulfillment exhibited larger CN amplitudes in avoidance–avoidance situations relative to low-conflict situations; to a lesser extent, they also exhibited larger CN amplitudes in approach–approach situations relative to low-conflict situations. By contrast, people reporting lower need fulfillment exhibited CN amplitudes that poorly discriminated the three decision situations. These results suggest that need fulfillment may promote self-coherent functioning by increasing people’s receptivity to and processing of events that challenge their abilities to make efficient, self-congruent choices.     

The British state ‘security syndrome’ and Muslim diversity: challenges for liberal democracy in the age of terror

This paper explores the securitisation of British Muslims within a global context in which tensions are reignited by the threat that Islamist terrorism, and Islam more generally, are considered to pose to the West. While Western involvement in Muslim-majority countries continues to fuel the idea of a ‘clash of civilisations’, domestic responses to terrorism and extremism take forward its rhetoric. At the heart of 15 years of wide-ranging responses lies the state ‘security syndrome’. Operating through the paradigm of risk reduction, the British state has reasserted its primary role as the distributor of security in ways that move beyond the surgical targeting of violent Islamists and their supporters and instead risk impacting on Muslims qua Muslims. Counter-terrorism and anti-extremism notions and practices that conflate security risks and cultural threats signal that Great Britain is a liberal democracy that is yet to fully foster positive inter-community relations and achieve social cohesion.     

Maternal aggression toward infanticidal males of different social status in wild house mice (Mus musculus domesticus)

Maternal aggression was examined in wild female mice (Mus musculus domesticus) derived from animals trapped in Alberta, Canada. Lactating females were tested for their behavior toward intruder males during the time of postpartum estrus while housed in a two-cage apparatus containing a defensible nest area. Prior to being used as intruders, sexually naive males were screened for their behavior toward a newborn pup (83% exhibited infanticide). Only infanticidal males were then housed in pairs and allowed to establish a dominance hierarchy. Dominance status was further verified by a urine marking test. The dominant and subordinate infanticidal males were then placed into a lactating female's cage and observed for 1 hr. The test was terminated immediately when a male began to attack the pups. Lactating females attacked the males in both groups, but subordinate males received more intense attacks than dominant males. Dominant males elicited significantly more fear/defense behavior than subordinate intruders. All of the dominant males and only one submissive male attacked the pups. Females were thus successful in blocking infanticide only by infanticidal subordinate males. Since females do not persist in attacking males with high fighting ability, one function of maternal aggression could be to assess the fighting, and resource holding, potential of a future mate. © 1994 Wiley-Liss, Inc.     

Antipredator behavior of Swiss-Webster mice in a visible burrow system

Swiss-Webster mice living in a visible burrow system (VBS) reacted to presentation of a live cat in the surface area of the VBS by retreat to the burrows and reductions in nondefensive behaviors such as eating and drinking. Live eat-exposed subjects remained in the burrows 14 hr or more, while subjects exposed to a toy (plush) cat prior to live cat exposure reemerged almost immediately and made many contacts with the toy cat. However, subjects exposed first to the cat and later to a toy cat showed intermediate surface reemergence times and cat contacts during toy cat tests, indicating strong sensitization effects of prior live cat exposure. Previous studies indicated that rats in this situation show retreat to the burrows, surface avoidance, and reduction in nondefensive behaviors. The mouse pattern was similar, with the notable exception that in the first 5min block after cat presentation, mice rapidly alternated retreat to the burrow chambers with reappearance in the tunnel segment near the surface, to scan the surface visually and sniff. Movement during this time block involved a stretch attend posture characteristic also of risk assessment activities in rats. Such visual and olfactory inspection of the cat is not seen in rats in the VBS. This difference may be related to the finding that rats, but not mice, emit ultrasonic “alarm cries” during and after cat exposure. © 1995 Wiley-Liss, Inc.     

Offensive and defensive bite-target topographies in attacks by lactating rats

The attacks by resident lactating Wistar rats on sexually naive conspecifics of both sexes were examined. Male and female intruders were equally attacked in terms of frequency and number of bites, but the topographies of biting seen in these encounters were different. Similarly to male-male agonistic interactions, females were attacked in a fashion which avoided bites to the head and snout (“offensive” attack), whereas males were frequently bitten on such vulnerable regions (“defensive” attack). This dichotomy in bite pattern suggests that different motivations and functions underlay maternal aggression in these situations. The defensive attack on males may be a deterrent to infanticide since only male intruders counterattack lactating females and kill their pups. The attack on females may be concerned with resource competition.
