Money for microbes—Pathogen avoidance and out‐group helping behaviour

Humans have evolved various adaptations against pathogens, including the physiological immune system. However, not all of these adaptations are physiological: the cognitive mechanisms whereby we avoid potential sources of pathogens—for example, disgust elicited by uncleanliness—can be considered as parts of a behavioural immune system (BIS). The mechanisms of BIS extend also to inter‐group relations: Pathogen cues have been shown to increase xenophobia/ethnocentrism, as people prefer to keep their societal in‐group norms unaltered and “clean.” Nonetheless, little is known how pathogen cues influence people's willingness to provide humanitarian aid to out‐group members. We examined how pathogen cues affected decisions of providing humanitarian aid in either instrumental (sending money) or non‐instrumental form (sending personnel to help, or accepting refugees), and whether these effects were moderated by individual differences in BIS sensitivity. Data were collected in two online studies (Ns: 188 and 210). When the hypothetical humanitarian crisis involved a clear risk of infection, participants with high BIS sensitivity preferred to send money rather than personnel or to accept refugees. The results suggest that pathogen cues influence BIS‐sensitive individuals' willingness to provide humanitarian aid when there is a risk of contamination to in‐group members.     

Behavioural automaticity moderates and mediates the relationship of trait self-control and physical activity behaviour

Objectives: Trait self-control has been shown to be associated with physical activity behaviour. However, in contrast with the theoretical assumption underlying the strength model of self-control, self-control seems to be more important for automatic compared with controlled behaviours. It is argued that self-control might facilitate the formation of adaptive habits (behavioural automaticity) and therefore enhance health behaviour through an indirect effect. The credibility of this hypothesis was empirically assessed in a proof-of-concept study.

Methods: In a prospective design study with two laboratory sessions, participants (N = 124) completed standardised questionnaires assessing trait self-control and behavioural automaticity as predictors (1st session) and actual physical activity behaviour (after one week) as the dependent variable (2nd session).

Results: The predictive power of self-control was stronger for participants with high behavioural automaticity compared with participants with low behavioural automaticity. Furthermore, automaticity mediated the relationship between self-control and behaviour.

Discussion: Behavioural automaticity appears to be a helpful construct for specifying the relationship between self-control and physical activity. Our results support the approach of effortless self-control and self-control success, an extension of the strength model of self-control which assumes that self-control is helpful in creating effective routines. In future studies, causal relationships should be examined using more robust and rigorous research designs.     

Revisiting a meta-analysis of helpful aspects of therapy in a community counselling service

This small scale mixed methods study examines helpful events in a community counselling setting, categorising impacts of events according to Timulak’s [(2007). Identifying core categories of client-identified impact of helpful events in psychotherapy: A qualitative meta-analysis. Psychotherapy Research, 17, 305–314] meta-synthesis of significant events research. Comparisons were made between the types of impacts reported as helpful by clients receiving cognitive behavioural therapy (CBT) or relational integrative counselling. Seventy-five clients identified 291 significant events on 216 Helpful Aspects of Therapy (HAT) forms. The findings broadly reflect all nine impacts identified by Timulak (2007). The study also suggests that a potential new category, ‘voicing’ may exist. Differences between the types of impacts reported as helpful by clients in CBT and integrative therapy showed a higher percentage of CBT clients reporting ‘behavioural change/problem solution’, ‘reassurance’ and ‘client involvement’ as helpful. Differences in other categories were not statistically significant.     

Positive and negative behavioural intentions towards refugees in Turkey: The roles of national identification,threat, and humanitarian concern

The present research investigated positive and negative behavioural intentions towards Syrian refugees in Turkey. The behavioural intentions were examined in relation to national identification, perception of threat, and humanitarian concerns. A questionnaire was conducted among Turkish participants (n = 605) and the results showed that respondents made a distinction between negative and positive behavioural intentions towards Syrian refugees. Further, higher national identification was associated with more negative and less positive behavioural intentions, and perception of threat was responsible for these associations. In addition, humanitarian concern was associated with more positive behavioural intentions and less negative ones. Additionally, stronger humanitarian concern weakened the association between threat perceptions and negative behavioural intentions but also strengthened the association between higher threat and lower positive behavioural intentions.

Trait BIS predicts alpha asymmetry and P300 in a Go/No‐Go task

Inspired by the revised Behavioural Inhibition System (BIS) theory the present study probed the association between individual differences in Trait BIS and electroencephalogram indicators of conflict processing/inhibition. Sixty‐nine male participants either high or low in Trait BIS completed a Go/No‐Go task while the electroencephalogram was recorded. As expected, Trait BIS was associated with the No‐Go‐anteriorisation of the P300 event‐related potential (i.e. an index of response inhibition presumably generated in the dorsal anterior cingulate—an area implicated in conflict processing) and with No‐ Go‐related changes towards left frontal alpha activity (i.e. presumably more activity in right prefrontal cortex—an area implicated in response inhibition). These findings support the role of conflict processing attributed to BIS functioning in the revised theory. Copyright © 2009 John Wiley & Sons, Ltd.     

Extinction of drug cue reactivity in methamphetamine-dependent individuals

Conditioned responses to drug-related environmental cues (such as craving) play a critical role in relapse to drug use. Animal models demonstrate that repeated exposure to drug-associated cues in the absence of drug administration leads to the extinction of conditioned responses, but the few existing clinical trials focused on extinction of conditioned responses to drug-related cues in drug-dependent individuals show equivocal results. The current study examined drug-related cue reactivity and response extinction in a laboratory setting in methamphetamine-dependent individuals. Methamphetamine cue-elicited craving was extinguished during two sessions of repeated (3) within-session exposures to multi-modal (picture, video, and in-vivo) cues, with no evidence of spontaneous recovery between sessions. A trend was noted for a greater attenuation of response in participants with longer (4-7 day) inter-session intervals. These results indicate that extinction of drug cue conditioned responding occurs in methamphetamine-dependent individuals, offering promise for the development of extinction- based treatment strategies.     

Balanced states of mind in psychopathology and psychological well-being

The balanced states of mind (BSOM) model proposes that coping with stress and psychological well-being is a function of the BSOM ratio of positive thoughts to the sum of positive and negative thoughts. Based on different BSOM ratios, different BSOM categories are constructed to quantitatively differentiate levels of coping with stress and psychological well-being. The cognitive content-specificity hypothesis states that there are unique themes of semantic content in self-reported automatic thoughts particular to depression or anxiety. This study investigated the BSOM model and its cognitive content-specificity for depression, anxiety, anger, stress, life satisfaction, and happiness, based on negative and positive automatic thoughts. Three hundred and ninety-eight college students from Singapore participated in this study. First, BSOM ratio and positive automatic thoughts were positively correlated with life satisfaction and happiness, and negatively correlated with stress, anxiety, depression, and anger. In contrast, negative automatic thoughts were positively correlated with stress, anxiety, depression, and anger, and negatively correlated with life satisfaction and happiness. Second, levels of psychopathology and psychological well-being were statistically differentiable among the BSOM categories for depression, happiness, perceived stress, and life satisfaction; and less statistically differentiable among the BSOM categories for anxiety and anger, as expected based on the BSOM model and cognitive content-specificity hypothesis. Third, the results were more supportive of the BSOM model for depression, followed by happiness, perceived stress, life satisfaction, anxiety, and anger in terms of percentage of variance accounted for by BSOM categories, as expected based on the cognitive content-specificity hypothesis. Taken together, the results suggested that the more moderately positive thoughts one has (balanced by negative thoughts), the better mental health outcomes one has. Implications and limitations of these findings are discussed.     

Group-based problem-solving therapy in self-poisoning females: A pilot study

Aims: The treatment of suicidal behaviour remains limited in efficacy. This pilot study assessed the effectiveness of a time-limited, group-based problem-solving therapy intervention compared with a treatment as usual control group, in females who self-poison. Method: A total of 18 clients were equally randomised to treatment or control groups. All clients were assessed using standardised questionnaires for depression, hopelessness, suicidal ideation and social problem-solving skills, at pre-treatment, post-treatment and two months follow-up. Results: The treatment group experienced significant reductions in levels of depression, hopelessness, suicidal ideation and improvements in self-assessed social problem-solving skills. Improvements in mental health and aspects of self-assessed problem-solving skills for the treatment group continued to be evident at two months follow-up. The control group did not change significantly over time on mental health measures or social problem solving abilities. Conclusion: Although limited by small sample size, the results suggest that group-based problem-solving therapy is effective in the management of deliberate self-poisoning. This paper is a unique contribution in that it examines the implementation of problem solving therapy with a homogenous population and in a group format. Methodological concerns and directions for future research are discussed.     

Linking serial residential burglary: comparing the utility of modus operandi behaviours,geographical proximity,and temporal proximity

Whilst case linkage is used with serious forms of serial crime (e.g. rape and murder), the potential exists for it to be used with volume crime. This study replicates and extends previous research on the behavioural linking of burglaries. One hundred and sixty solved residential burglaries were sampled from a British police force. From these, 80 linked crime pairs (committed by the same serial offender) and 80 unlinked crime pairs (committed by two different serial offenders) were created. Following the methodology used by previous researchers, the behavioural similarity, geographical proximity, and temporal proximity of linked crime pairs were compared with those of unlinked crime pairs. Geographical and temporal proximity possessed a high degree of predictive accuracy in distinguishing linked from unlinked pairs as assessed by logistic regression and receiver operating characteristic analyses. Comparatively, other traditional modus operandi behaviours showed less potential for linkage. Whilst personality psychology literature has suggested we might expect to find a relationship between temporal proximity and behavioural consistency, such a relationship was not observed.
