When gains loom larger than losses: reversed loss aversion for small amounts of money

Previous research has generally shown that people are loss averse; that is, they weigh losses more heavily than gains. In a series of three experiments, we found that for small outcomes, this pattern is reversed, and gains loom larger than losses. We explain this reversal on the basis of (a) the hedonic principle, which states that individuals are motivated to maximize pleasure and to minimize pain, and (b) the assumption that small losses are more easily discounted cognitively than large losses are.     

Investigating Web‐Based Recruitment Sources: Employee testimonials vs word‐of‐mouse

Although the internet has dramatically changed recruitment practices, many web‐based recruitment sources have not yet been investigated. The present study examines the effects of web‐based employee testimonials and web‐based word‐of‐mouth (i.e., ‘word‐of‐mouse’) on organizational attraction. The source credibility framework is used to compare these company‐dependent and company‐independent recruitment sources. In a sample of potential applicants for a head nurse position, word‐of‐mouse was associated with higher organizational attractiveness than web‐based employee testimonials. However, potential applicants were more attracted when testimonials provided information about individual employees than about the organization. Conversely, word‐of‐mouse was associated with higher organizational attractiveness and more organizational pursuit behavior when it focused on the organization instead of on employees. Most of these effects were mediated by credibility perceptions.     

Football hooliganism: comparing self‐awareness and social identity theory explanations

The emergence of research interest in group violence in general and football hooliganism in particular has been explained by various models generally relying on situational or individual differences accounts. Yet, these two research traditions have largely evolved independently, showing little or no interaction. In the present study (N = 109), we integrate measures of these two approaches and the results reveal that social identity was more predictive of self‐reported physical aggression than of loss of private and public self‐awareness. Moreover, attitudes towards violence were the most marked predictor variables of both physical and verbal aggression. In the discussion, the moderator effect of social identity and attitudes about violence on physical aggression is elaborated upon. Copyright © 2007 John Wiley & Sons, Ltd.     

Axis I screens and suicide risk in jails: a comparative analysis

Mental health professionals conducting screenings in jail settings face formidable challenges in identifying inmates at risk for major depression and suicide. Psychologists often rely on correctional staff to provide initial appraisals of those inmates requiring further evaluation. In a sample of 100 jail detainees, the effectiveness of two specialized screens (the Referral Decision Scale and Mental Disability/Suicide Intake Screen or MDSIS) and one general screen (Personality Assessment Screener or PAS) was evaluated. For suicidal ideation, the MDSIS composite score evidenced promise (sensitivity = 1.00; specificity = 0.71). In ruling out major depression, the PAS Negative Affect subscale was useful for the inmate participants.     

Does negative mood influence self-report assessment of individual and relational measures? An experimental analysis

The present study was designed to test the influence of negative mood on the self-report of individual and relational correlates of depression and marital distress. The authors applied a combined experimental mood induction procedure, based on music, autobiographical recall, and environmental manipulation. Results showed that the mood manipulation was effective, and the depressed Mood Induction Procedure (MIP) and neutral MIP groups did not differ in their self-rated measures of the above-mentioned variables. In conclusion, the authors argue that these measures are generally insensitive to depressed mood, providing an important contribution to this literature.     

Both exposure to a novel context and associative learning induce an upregulation of AKAP150 protein in mouse hippocampus

A-kinase anchoring protein 150 (AKAP150) is a multi-enzyme signaling complex that coordinates the action of PKA, PKC, and PP2B at neuronal membranes and synapses. We measured levels of AKAP150 protein in the hippocampus 6h after training mice in a contextual fear conditioning paradigm. In contextual fear conditioning mice learn to associate a context with a footshock presentation. Mice were divided in four experimental groups with different training protocols: naive, no footshock exposure, immediate footshock exposure, and footshock 3min after exposure to the context. We found that AKAP150 protein levels were increased upon exposing mice to the novel context independent of the training protocol. However, when the animals were habituated to the experimental context, only mice that learned to associate the context with the footshock showed an upregulation of AKAP150. We suggest that upregulated levels of AKAP150 contribute to processing the exposure to a novel context and associative learning.     

Online mental health treatment: concerns and considerations.

Concerns and considerations have emerged as mental health professionals contemplate the provision of mental health treatment over the Internet. This paper identifies perceptions of online mental health treatment among a national sample of 2,098 social workers, psychologists, and other professionals. These professionals were unlikely to provide online mental health treatment, although some used the Internet as an adjunct to clinical practice. They noted specific concerns related to the provision of mental health treatment online, including confidentiality of client information and liability issues. We explore these issues and discuss implications for professionals who provide mental health treatment.     

More than mere mimicry? The influence of emotion on rapid facial reactions to faces

Within a second of seeing an emotional facial expression, people typically match that expression. These rapid facial reactions (RFRs), often termed mimicry, are implicated in emotional contagion, social perception, and embodied affect, yet ambiguity remains regarding the mechanism(s) involved. Two studies evaluated whether RFRs to faces are solely nonaffective motor responses or whether emotional processes are involved. Brow (corrugator, related to anger) and forehead (frontalis, related to fear) activity were recorded using facial electromyography (EMG) while undergraduates in two conditions (fear induction vs. neutral) viewed fear, anger, and neutral facial expressions. As predicted, fear induction increased fear expressions to angry faces within 1000 ms of exposure, demonstrating an emotional component of RFRs. This did not merely reflect increased fear from the induction, because responses to neutral faces were unaffected. Considering RFRs to be merely nonaffective automatic reactions is inaccurate. RFRs are not purely motor mimicry; emotion influences early facial responses to faces. The relevance of these data to emotional contagion, autism, and the mirror system-based perspectives on imitation is discussed.     

The joint effects of personality and workplace social exchange relationships in predicting task performance and citizenship performance

This field study examines the joint effects of social exchange relationships at work (leader-member exchange and team-member exchange) and employee personality (conscientiousness and agreeableness) in predicting task performance and citizenship performance. Consistent with trait activation theory, matched data on 230 employees, their coworkers, and their supervisors demonstrated interactions in which high quality social exchange relationships weakened the positive relationships between personality and performance. Results demonstrate the benefits of consonant predictions in which predictors and outcomes are matched on the basis of specific targets. We discuss theoretical and practical implications.
