The time course of resource allocation in spider-fearful participants during fear reactions

The dynamics of resource allocation to pictures of spiders and other animals in spider-fearful participants was investigated. The task of the participants was to respond rapidly and accurately to various probe stimuli superimposed on pictures of different animals. These were arguably fear relevant (spiders, snakes, and wolves) and fear irrelevant (beetles, turtles, and rabbits). The probes were shown with different stimulus onset asynchronies (SOAs) from picture onset to address the dynamics of resource allocation. A larger allocation of resources to spider pictures than to pictures of all other animals, with no difference between the latter regarding resource allocation was found. For the task that demanded more resources the fear-related physiological responses decreased, suggesting that controlled processing modulates fear responses.     

Intending or Pretending? Automatic Evaluations of Goal Cues Discriminate True and False Intentions

This research presents a novel approach to discriminating between true and deceptive statements about intended future behavior. Arguing that true intentions are goal‐directed, we predict that people who genuinely intend to pursue a reported goal will implicitly evaluate goal‐relevant cues positively, whereas people who do not intend to pursue the goal will not. Participants in an experiment were instructed to tell the truth about a planned future behavior (true intention) or to falsely report that same behavior to mask their actual mock‐criminal intention (false intention). As predicted, an evaluative priming task showed that participants with true intention exhibited implicit positive evaluations of cues relevant to the reported goal, whereas participants with false intention did not. Subsequent analyses showed that implicit positivity significantly discriminated between true and false intentions. The findings are discussed in terms of theoretical contributions and implications for the development of future detection tools. Copyright © 2012 John Wiley & Sons, Ltd.     

Philo’s Argument from Evil in Hume’s Dialogues X: A Semantic Interpretation

Philo's argument from evil in a much-discussed passage in Part X of Hume's Dialogues concerning Natural Religion (1779) has been interpreted in three main ways: as a logical argument from evil, as an evidential argument from evil, and as an argument against natural theology's inference of a benevolent and merciful God from the course of the world. I argue that Philo is not offering an argument of any of these sorts, but is arguing that there is a radical disanalogy between the meanings of terms like ‘merciful’ and ‘benevolent’ when applied to God and human beings respectively. Drawing on the new ‘Irreligious Interpretation’ of Hume's philosophy developed by Paul Russell (2002, 2008), I suggest that the underlying aim of Philo's argument appears to be to show, in opposition to Christian teaching, that these terms, when applied to God, are in effect meaningless.     

Bottled memories: On how alcohol affects eyewitness recall

This study investigated how different doses of alcohol affected eyewitness recall. Participants (N = 126) were randomly assigned to three groups with different blood alcohol concentration (BAC), either a control group (mean BAC 0.00%, N = 42), a lower alcohol dose group (mean BAC 0.04%, N = 40), or a higher alcohol dose group (mean BAC 0.06%, N = 44). After consumption, participants witnessed a movie of a mock crime and were interviewed one week later. The main results showed that witnesses with the higher intoxication level recalled fewer details compared to witnesses with the lower intoxication level. The amount of alcohol consumed did not have an impact on the accuracy rate. No sex differences were found. The results are discussed in the light of past research. We conclude that more studies are needed before recommendations can be made to an applied setting.     

Globalisation and global justice

The discussion about justice has often been limited to a specific territory, i.e. a nation. However, globalisation has undermined the relevance of this presupposition. John Rawls's theory of justice is a starting point for contemporary discussions about justice. But, contrary to Rawls's view, principles of global justice should not only include principles of non-interference and respect for universal human rights, but also a principle of democratic legitimacy of global governance and a principle of global distributive justice. The notion of global justice is not uncontroversial. It is argued that the meaning of justice differs between different communities and, thus, one cannot hope for a universal approval of the concept of global justice, that a principle of global distributive justice does not take into account that global differences in wealth are caused by differences in the ambitions of individuals and nations and that the idea of global justice overlooks crucial institutional differences between a nation and the global situation. However, these arguments are not conclusive.     

Intensive video gaming improves encoding speed to visual short-term memory in young male adults

The purpose of this study was to measure the effect of action video gaming on central elements of visual attention using Bundesen's (1990) Theory of Visual Attention.To examine the cognitive impact of action video gaming, we tested basic functions of visual attention in 42 young male adults. Participants were divided into three groups depending on the amount of time spent playing action video games: non-players (< 2 h/month, N = 12), casual players (4–8 h/month, N = 10), and experienced players (> 15 h/month, N = 20). All participants were tested in three tasks which tap central functions of visual attention and short-term memory: a test based on the Theory of Visual Attention (TVA), an enumeration test and finally the Attentional Network Test (ANT). The results show that action video gaming does not seem to impact the capacity of visual short-term memory. However, playing action video games does seem to improve the encoding speed of visual information into visual short-term memory and the improvement does seem to depend on the time devoted to gaming. This suggests that intense action video gaming improves basic attentional functioning and that this improvement generalizes into other activities. The implications of these findings for cognitive rehabilitation training are discussed.     

Role stressors and exposure to workplace bullying: Causes or consequences of what and why?

Stressful working environments are commonly assumed to create conditions that can lead to bullying. Although environmental factors may relate to both exposure to and perpetration of workplace bullying, empirical knowledge is still limited regarding how environmental factors and bullying is causally linked. In line with interpretations of previous cross-sectional findings, the present study investigated an individual-level target-oriented model of role stressors as antecedents of exposure to workplace bullying, applying a two-wave longitudinal sample of the Norwegian working population. Results from structural regression analyses failed to identify any significant relationships between the role stressors and subsequent exposure to workplace bullying. However, prior exposure to workplace bullying accounted for subsequent variation in role ambiguity, role conflict, and role overload alike. The findings of the present study question conclusions regarding causality made in previous cross-sectional research on work-related factors as antecedents of exposure to workplace bullying. We argue that future research may benefit from adopting multilevel and actor-oriented perspectives in order to more fully understand how causal relationships between environmental factors and workplace bullying unfold.     

Assessing knowledge-intensive work environment: General versus situation-specific instruments

The aim of the present study is to examine to what extent general and situation-specific work environment instruments capture the salient work characteristics in a knowledge-intensive context. We conducted qualitative open-ended interviews with 30 employees (24 men and six women) from a Norwegian university department. The information from the interviews was content-analysed and coded on the scales of five work environment instruments; two general instruments (the General Nordic Questionnaire for Psychological and Social Factors at Work [QPSNordic] and the Job Diagnostic Survey [JDS]) and three situation-specific instruments (Assessing the climate for creativity [KEYS], Situational Outlook Questionnaire [SOQ], and the Organizational Climate Measure [OCM]). The results showed that situation-specific work environment instruments covered significantly more statements about the work environment than the general instruments. More statements could be categorized on the organization and individual levels, compared to group and leadership levels. The situation-specific instruments covered more statements than general instruments at the organization level. These statements were mainly related to the organizational context, social and relational characteristics, and encouragement of creativity and organizational impediments to creativity. The findings support the value of situation-specific instruments for assessing the work environment in knowledge-intensive organizations.     

Meditators and non-meditators on sustained and executive attentional performance

In order to gain a deeper understanding of the mindfulness construct and the mental health benefits associated with mindfulness-based programmes, the relation between mindfulness and its proposed core component attention was studied. Buddhist and Western mindfulness meditators were compared with non-meditators on tasks of sustained (SART) and executive (the Stroop Task) attention. Relations between self-reported mindfulness (FFMQ) and sustained and executive attention were also analysed. No significant differences were found between meditators and non-meditators either in sustained or executive attention. High scores on the FFMQ total scale and on Describe were related to fewer SART errors. High scores on Describe were also related to low Stroop interference. Mindfulness meditators may have an increased awareness of internal processes and the ability to quickly attend to them but this type of refined attentional ability does not seem to be related to performance on attention tests requiring responses to external targets.     

On the subject of homosexuality: What Freud said

The article explores Freud's writing on homosexuality, from his early hypotheses, expressed in his letters to Fleiss to his last observations in The Outline of Psychoanalysis, published in 1940 after his death. We trace the continuities as well as changes in his thinking, and have organized the paper conceptually, under the headings: 1) Bisexuality 2) Narcissism and Object choice, 3) On Normality and Pathology, and 4) The Quantitative factor and Aggression. We show that Freud was the first to confirm the existence of homosexualities, that he offers no black and white solution to the question of normality and pathology, although he contributes to the understanding of the vehemence that surrounds the subject, and that, in the considerable body of work, he has offered a rich and varied foundation for further thinking on the subject.
