Response Channel Activation and the Temporoparietal Junction

When we learn to make one motor response to one visual stimulus and a different motor response to another, representations of these stimulus–response associations must be maintained to efficiently transduce perception into action. When an irrelevant distractor is presented adjacent to a target stimulus, interference is observed when the two stimuli are associated with conflicting responses, presumably due to response channel activation by the incompatible information. We have explored the neural bases of these interference effects. In a previous study, patients with hemispatial neglect showed normal interference from contralesional flankers. In another study, patients with lesions of the lateral prefrontal cortex were found not to show interference from distractors presented in the contralesional hemifield. The current study provided a more anatomically detailed investigation of the effects of posterior association cortex lesions on flanker interference. Patients with chronic, unilateral lesions involving the temporoparietal junction (TPJ), two of whom had hemispatial neglect, were compared with patients with lesions of the posterior association cortex not involving the TPJ. All patients performed a color discrimination task at fixation while a congruent or incongruent colored flanker was briefly presented (16.7 ms) in the adjacent contralesional or ipsilesional hemifield. Patients with TPJ lesions showed no interference effects from the contralesional flankers. These results suggest that the TPJ, in combination with the dorsolateral prefrontal cortex, is involved in transducing perception into action.     

The Representation of Arithmetic Facts in Memory: Results from Retraining a Brain-Damaged Patient

This single case study was designed to gather evidence regarding whether the mental representations mediating multiplication fact retrieval make use of single or multiple codes. MC is a brain-damaged volunteer whose numerical processing impairments were limited to multiplication fact retrieval. He relearned three sets of multiplication facts. Each set was relearned in one of three input formats: Arabic, written verbal, or spoken verbal. Following training all facts were tested in all input formats. MC's posttraining performance was virtually error free and showed no effects of input format. However, reaction-time data showed fact retrieval was fastest when the training format matched the test format. Results are discussed in relation to single- and multiple-code models of multiplication fact retrieval.     

The allocation of time to temporally defined behaviors: responding during stimulus generalization.

In one stimulus condition, reinforcement depended on rats holding a lever for a duration having both minimum and maximum boundaries. During a second light intensity, reinforcement was not available for some rats; for others, reinforcement depended on a second response duration requirement. Generalization test stimuli controlled the same response durations found during training, and the amount of time allocated to a given response duration depended on the proximity of the test stimulus to the training stimulus which controlled that particular duration. The results indicated that a gradient of stimulus control does not reflect an underlying continuous change in responding, but is a result of the mixing of responses previously controlled by stimuli present during conditioning.     

Investigating the relationship between working memory and emotion regulation in mothers

Recent work suggests that executive functions, specifically working memory, may facilitate emotion regulation (ER). Here we examined whether measures of visuospatial working memory and verbal working memory relate to ER in a group of recent mothers. We found that while visuospatial working memory was associated with, and predictive of, self-reported measures of ER and emotion dysregulation—verbal working memory was correlated to only one dimension of emotion dysregulation. These findings suggest that working memory may play a unique role in everyday regulatory functioning. We frame our results in terms of the broader implications they may have for the potential role of executive functioning in parenting.     

'Experiencing' Alpha: Finding and Embodying the Spirit and Being Transformed--Empowerment and Control in a ('Charismatic') Christian Worldview

This article analyses the Alpha Course, the 15-session evangelising programme designed by Holy Trinity Brompton. It argues that it is a popular form of evangelism influenced by the 'charismatic' movement, which aims to initiate participants into a particular religious 'experience'. It further argues that the course aims to stimulate participants to locate themselves, psychologically and socially, within a 'charismatic' worldview. The article aims to examine, phenomenologically, the Alpha 'experience', through an ethnographic analysis of the course and in particular its Holy Spirit weekend. The article relates Alpha to the wider beliefs and practices of the 'charismatic' movement and religious experience and assesses what it means for contemporary Christianity. It seeks to show that the initial 'experience' gained on the Alpha Course is continued within 'charismatic' experience in church meetings and services and looks at the personal empowerment and social control that may be at work.     

Successful emotion regulation requires both conviction and skill: beliefs about the controllability of emotions,reappraisal, and regulation success

To succeed in self-regulation, people need to believe that it is possible to change behaviour and they also need to use effective means to enable such a change. We propose that this also applies to emotion regulation. In two studies, we found that people were most successful in emotion regulation, the more they believed emotions can be controlled and the more they used an effective emotion regulation strategy – namely, cognitive reappraisal. Cognitive reappraisal moderated the link between beliefs about the controllability of emotion and success in emotion regulation, when reappraisal was measured as a trait (Study 1) or manipulated (Study 2). Such moderation was found when examining the regulation of disgust elicited by emotion-inducing films (Study 1), and the regulation of anger elicited by real political events (Study 2). We discuss the implications of our findings for research and practice in emotion regulation.     

‘It seems at the moment my career is dependent on factors outside of my control’: reflections on graduates’ experiences of employment and career enactment in an era of economic uncertainty and austerity

ABSTRACT

This paper explores contested notions of the purpose of education and careers work. The research for the paper examines public sector employee reactions to notion of a psychological contract breach, when cuts in funding put their jobs and careers at risk. It argues that, in this environment, the search for career fulfilment can be marked by feelings of cruel optimism, wicked problems and broken expectations. The findings are then used to present the case for further research, firstly, to address the notion of possible selves, as individuals explore alternative identity affirming career opportunities; and secondly, the impact of changes in public policy on the processes of psychological contracting between students and staff in further and higher education.     

Sojourners’ Ineffective Sociocultural Adaptation: Paranoia as a Joint Function of Distrust toward Host Nationals and Neuroticism

The present study examines how sojourners’ paranoia mediates the negative relationship between their distrust toward host nationals and sociocultural adaptation, and how sojourners’ neuroticism moderates this mediated relationship. By conducting a two-part survey study with U.S. undergraduate students who traveled abroad for academic programs, I found that only among neurotic sojourners, distrust toward host nationals was negatively related to sociocultural adaptation, mediated by paranoia. These findings suggest that distrust-related cognition and emotion as well as neuroticism are all important predictors of sociocultural adaptation, and shed light on the inquiry regarding sojourners’ adaptation and distrust/trust.
