Counterfactual thinking and stereotypes: The nonconformity effect

Past research has shown that counterfactual thinking (‘if only…’) is related to judgements of responsibility for negative events. It has also shown that behaviours deviating from the target's own behavioural standard (intrapersonal norm) are likely to trigger counterfactuals—the so‐called exceptional‐routine effect. In the present research, we demonstrate that behaviours deviating from a social category's behavioural standard (social norm) are also likely to trigger counterfactuals—what may be called the nonconformity effect. Two studies investigated counterfactual thinking regarding a rape case, classifying counterfactuals according to their conformity versus nonconformity to relevant social norms, and their focus on actions versus inactions. In Study 1, participants with higher endorsement of the rape victim stereotype generated more counterfactuals on the victim's non‐conforming inactions than did participants with lower stereotype endorsement. The presence of a nonconformity effect was confirmed in Study 2, where participants rated their agreement with externally generated counterfactuals. Moreover, in Study 2, counterfactuals focused on the victim's non‐conforming inactions predicted responsibility attribution to the victim through the mediating role of perceived avoidability of the event.

The factor structure of the Eysenck Personality Profiler in Russia

One hundred and seventy seven males and 399 females completed a translated short version of the Eysenck Personality Profiler (EPP-S). Two hundred and ninety four Ss also completed the EPQ. By means of item analysis, further shortening of the EPP was achieved, while retaining adequate psychometric characteristics and convergent validity with EPQ scales. Confirmatory factor analysis (CFA) confirmed the Eysenck hierarchical model of personality with three basic dimensions and showed stability of the EPP factor structure across genders and sub-samples of different origin. However, CFA showed that only E and P were independent, while N was correlated with E and P.     

Towards mouse models of perseveration: a heritable component in extinction of operant behavior in fourteen standard and recombinant inbred mouse lines

Extinction of instrumental responses is an essential skill for adaptive behavior such as foraging. So far, only few studies have focused on extinction following appetitive conditioning in mice. We studied extinction of appetitive operant lever-press behavior in six standard inbred mouse strains (A/J, C3H/HeJ, C57BL/6J, DBA/2J, BALB/cByJ and NOD/Ltj) and eight recombinant inbred mouse lines. From the response rates at the end of operant and extinction training we computed an extinction index, with higher values indicating better capability to omit behavioral responding in absence of reward. This index varied highly across the mouse lines tested, and the variability was partially due to a significant heritable component of 12.6%.To further characterize the relationship between operant learning and extinction, we calculated the slope of the time course of extinction across sessions. While many strains showed a considerable capacity to omit responding when lever pressing was no longer rewarded, we found a few lines showing an abnormally high perseveration in lever press behavior, showing no decay in response scores over extinction sessions.No correlation was found between operant and extinction response scores, suggesting that appetitive operant learning and extinction learning are dissociable, a finding in line with previous studies indicating that these forms of learning are dependent on different brain areas. These data shed light on the heritable basis of extinction learning and may help develop animal models of addictive habits and other perseverative disorders, such as compulsive food seeking and eating.     

Communication in social networks: Effects of kinship,network size,and emotional closeness

Communication is important in preventing social relationships from decaying over time. This study examined the effects of social network size, emotional closeness, and type of relationship (kinship vs. friendship) on communication patterns in the social networks of 251 women. Participants with large kin networks had longer times to last contact to both kin and friends. Participants with high levels of emotional closeness in their networks had shorter times to last contact. The effect of emotional closeness on time to last contact was greater for kin than for friends. These results demonstrate that time to last contact is closely tied to emotional closeness and suggest that the costs of maintaining kin relationships are lower than the costs of maintaining friendships.     

Friend or foe? The role of latent inhibition in predator and non-predator labelling by coral reef fishes

In communities of high biodiversity, the ability to distinguish predators from non-predators is crucial for prey success. Learning often plays a vital role in the ability to distinguish species that are threatening from those that are not. Many prey animals learn to recognise predators based on a single conditioning event whereby they are exposed to the unknown predator at the same time as alarm cues released from injured conspecifics. The remarkable efficiency of such learning means that recognition mistakes may occur if prey inadvertently learn that a species is a predator when it is not. Latent inhibition is a means by which prey that are pre-exposed to an unknown species in the absence of negative reinforcement can learn that the unknown animal is likely not a threat. Learning through latent inhibition should be conservative because mistakenly identifying predators as non-predators can have fatal consequences. In this study, we demonstrated that a common coral reef fish, lemon damselfish, Pomacentrus moluccensis can learn to recognise a predator as non-threatening through latent inhibition. Furthermore, we showed that we could override the latent inhibition effect by conditioning the prey to recognise the predator numerous times. Our results highlight the ability of prey fish to continually update the information regarding the threat posed by other fishes in their vicinity.     

Shared service centers and professional employability

This paper presents case study evidence of evolutionary changes in business support functions resulting in a fundamental hollowing out of the professional space over time and distance, creating the ‘hourglass’ profession. In an IT-enabled, boundaryless world, many professional activities can now be undertaken, in the manner of the Martini slogan, ‘any time, any place, anywhere’.This paper aims:

• ? 

  To investigate the shared service center as an emerging organizational form with the potential to drive fundamental change in the nature and location of professional work.

• ? 

  To explore the impact of these changes for individual professional workers, and to highlight the need for a greater focus on individual employability as the driver of an overall career trajectory.
