Relation of transliminality and sensation seeking

The Revised Transliminality Scale and Zuckerman's Sensation Seeking Scale (Form V) were administered to 83 psychology undergraduates. Weak positive correlations suggested that participants scoring high on the Transliminality Scale tended to be more experience seeking and, overall, more inclined to score sensation seeking.     

‘Humane intervention’: the international protection of animal rights

This paper explores the international implications of liberal theories which extend justice to sentient animals. In particular, it asks whether they imply that coercive military intervention in a state by external agents to prevent, halt or minimise violations of basic animal rights (‘humane intervention’) can be justified. In so doing, it employs Simon Caney's theory of humanitarian intervention and applies it to non-human animals. It argues that while humane intervention can be justified in principle using Caney's assumptions, justifying any particular intervention on behalf of animals is much more difficult – and in present circumstances impossible. If these claims are correct, a number of important conclusions follow. First, all states lack legitimacy because of the horrors that they inflict upon animals. As a result of this, all states are prima facie liable to intervention by external agents. To remedy this situation, all states have the responsibility to massively transform their relationship with non-human animals, and to build international institutions to oversee the proper protection of their most basic rights.     

Load effects in attention: Comparing tasks and age groups

Attention is limited in terms of both capacity (i.e., amount of information attended) and selectivity (i.e., the degree to which non-attended information is nonetheless processed). One of the seminal theories in the field, load theory, predicts that these two aspects of attention interact in systematic ways. Specifically, load theory predicts that when the amount of information to attend is less than the available capacity, spare attention will naturally leak out to unattended items. While load theory has found a great deal of empirical support, the robustness of the findings has recently been called into question, in particular with respect to the extent to which the predictions are borne out across different tasks and populations. Here we report tests of perceptual load effects in two different tasks (change detection and enumeration) and in two populations (adults and 7- to 8-year-old children). Adults’ accuracies did not demonstrate the predicted interaction between the capacity and selection dimensions, whereas children’s performance, in addition to being overall worse than adults, did show the interaction. The overall lower accuracy of children was seen to be the result of a larger performance decrement in response to capacity demands, distracting information, and their interaction. Interestingly, while these results were seen at the level of the two tasks, there was no within-participants correlation across tasks. Overall, these results suggest that maturation-related changes attenuate the magnitude of distractor effects in attention, which in turn limits the evidence for interactions between capacity and selection in high-functioning populations.

     

Depression in South Asian women: Asian women's beliefs on causes and cures

A qualitative, grounded theory approach within a constructivist paradigm is employed to explore perceptions of causes and cures of depression in South Asian women. Ten Asian women suffering from depression and three of their carers were interviewed about their beliefs around the cause of their own and their relative's depression, and the implications of these beliefs for treatment. Findings suggested that understanding their experience of conflicting cultural expectations, distinctions between psychosocial, spiritual, physical health problems and communication problems (general and culture specific) were central to these women's experiences of depression The implications of results for services are discussed and limitations of the study considered in line with criteria developed for constructivist research.     

Experiential avoidance and aversive visual images: response delays and event-related potentials on a simple matching task

In Experiment 1, participants high (n=15) or low in avoidance (n=14), as measured by the Acceptance and Action Questionnaire, completed a simple matching task that required them to choose whether or not to look at an aversive visual image. Only the high-avoidance participants took longer to emit a correct response that produced an aversive rather than a neutral picture. Additionally, the high-avoiders reported greater levels of anxiety following the experiment even though they rated the aversive images as less unpleasant and less emotionally arousing than their low-avoidant counterparts. In Experiment 2, three groups, representing high-, mid- and low-avoidance (n=6 in each) repeated the matching task with the additional recording of event-related potentials (ERPs). The findings of Experiment 1 were replicated in terms of reaction times and subjective ratings. The ERPs confirmed that the participants attended to the content of the images and differentiated between the aversive and neutral image types. The ERPs also showed significantly greater negativity for electrodes over the left hemisphere relative to the midline for only the high-experiential avoidance (EA) group. Given the left hemisphere dominance for language, the data suggest that the high-EA group engaged in verbal strategies to regulate their emotional responses.     

Do generation and regulation of emotions interact? Examination of their relationships in young adults

Emotions can be generated in response to inherently emotional perceptual properties of a stimulus (‘bottom up’) and in response to cognitive interpretations of an event (‘top down’). Similarly, emotion regulation (ER) strategies may deploy bottom-up or top-down processes, however the specific nature of these processes remains unclear. In this study we sought to replicate and extend previous studies that have investigated the interaction between ER and emotion generation. Specifically, we examined the relationship between both methods of emotion generation and ER in a sample of 75 undergraduate students who completed self-report questionnaires and a behavioral task of ER. We attempted to extend previous research by testing whether the positive effect of cognitive reappraisal on top-down generated emotions was specific to reappraisal or true of multiple ER strategies. Overall there was a main effect of generation such that top-down generated emotion was better regulated by cognitive reappraisal, expressive suppression, and appraisal strategies. We also found a main effect of ER such that cognitive reappraisal was perceived as the most successful ER strategy. We argue that ER is a state-dependent process that includes dynamic cycles between emotion generation and regulation processes. We further discuss expressive suppression as a top-down emotion regulation strategy in the context of our study despite debated literature.
