Weapons and violence: A review of theory and research

Weapons are used in approximately one quarter of all violent incidents and the majority of homicides in the US, and the UK. Despite their overwhelming contribution to violent harm, theories of weapon related behaviors are scarce, and little is known of their correlates. This paper reviews available theories of weapon related behavior and identifies a number of motivations for weapon carrying, such as self defense, victim coercion, causing harm and self presentation. Correlates of weapon carrying and weapon use such as age, gender, socioeconomic status, exposure to weapons and history of aggression are explored and a number of limitations to current research approaches are identified. The review concludes with a discussion of future directions for research.     

Feelings of control: Contingency determines experience of action

The experience of causation is a pervasive product of the human mind. Moreover, the experience of causing an event alters subjective time: actions are perceived as temporally shifted towards their effects [Haggard, P., Clark, S., & Kalogeras, J. (2002). Voluntary action and conscious awareness. Nature Neuroscience, 5(4), 382-385]. This temporal shift depends partly on advance prediction of the effects of action, and partly on inferential “postdictive” explanations of sensory effects of action. We investigated whether a single factor of statistical contingency could explain both these aspects of causal experience. We studied the time at which people perceived a simple manual action to occur, when statistical contingency indicated a causal relation between action and effect, and when no such relation was indicated. Both predictive and inferential “postdictive” shifts in the time of action depended on strong contingency between action and effect. The experience of agency involves a process of causal learning based on statistical contingency.     

The influence of perceptual and semantic categorization on inhibitory processing as measured by the N2–P3 response

In daily activities, humans must attend and respond to a range of important items and inhibit and not respond to unimportant distractions. Our current understanding of these processes is largely based on perceptually simple stimuli. This study investigates the interaction of conceptual-semantic categorization and inhibitory processing using Event Related Potentials (ERPs). Participants completed three Go–NoGo tasks that increased systematically in the degree of conceptual-semantic information necessary to respond correctly (from single items to categories of objects and animals). Findings indicate that the N2 response reflects inhibitory processing but does not change significantly with task difficulty. The P3 NoGo amplitude, on the other hand, is attenuated by task difficulty. Further, the latency of the peak of the P3 NoGo response elicited by the most difficult task is significantly later than are the peaks detected during performance of the other two tasks. Thus, the level of complexity of conceptual-semantic representations influences inhibitory processing in a systematic way. This inhibition paradigm may be a key for investigating inhibitory dysfunction in patient populations.     

The Prospect of a Global Ethic on HIV/AIDS: The Religions and the Science–and–Religion Dialogue

This article introduces essays from a 2001 symposium on a global ethic and the issue of the spread of HIV/AIDS. The symposium began with the assumption that we can determine the possibility for such a global ethic if we both explore the potential of an interreligious dialogue and do so in the context of a science–and–religion dialogue. I argue that while the possibilities for a global ethic, in particular addressing the issue of HIV/AIDS, may be debated, the results of this symposium suggest that the dialogue ought to be continued and that there is significant potential in the interfaith dialogue for creating models for both an ethic and specific strategies for action.

Introducing Mindfulness to Clinical Psychologists in Training: An Experiential Course of Brief Exercises

A 14 session, structured, mindfulness skills group utilizing short (10 min) practices was undertaken by clinical psychologists in training as a voluntary lunchtime activity. The present study was a preliminary investigation into whether a short course of brief mindfulness exercises could facilitate the development of personal understandings of mindfulness without requiring a significant time commitment that might impinge upon participants’ ability to take part. Quantitative and qualitative evaluations suggested that the course could be a useful experiential introduction to mindfulness for clinicians. The results also suggested that the format of frequent, brief exercises could have utility for conducting mindfulness-based training in time-limited environments but further research is required to examine the effects of frequency and duration of practice on the development of mindfulness skills.     

A Propensity Score Analysis of Homework Adherence-Outcome Relations in Cognitive Behavioral Therapy for Depression

Little is known about whether or not a consistently high level of homework adherence over the course of therapy benefits patients. This question was examined in two samples of patients who were receiving individual Cognitive Behavioral Therapy (CBT) for depression (Ns = 128 [Sequenced Treatment Alternatives to Relieve Depression: STAR-D] and 183 [Continuation Phase Cognitive Therapy Relapse Prevention: C-CT-RP]). Logistic and linear regression and propensity score models were used to identify whether or not clinician assessments of homework adherence differentiated symptom reduction and remission, as assessed by the Hamilton Depression Rating Scale-17 (HDRS-17), the Quick Inventory of Depressive Symptomatology–Self-Reported Scale (QIDS-SR), and the QIDS–Clinician Scale (QIDS-C). CBT-related response and remission were equally likely between both high and low homework adherers in both studies and in all models. But in propensity adjusted models that adjusted for session attendance, for both the STAR-D and C-CT-RP samples, greater homework adherence was significantly associated with greater response and remission from depression in the first and last 8 sessions of CBT. Our results suggest that homework adherence can account for response and remission early and late in treatment, with adequate session attendence.
