Revealing the nuanced associations between facets of trait impulsivity and reactive and proactive aggression

Although impulsivity has been repeatedly associated with aggression, specific associations between facets of impulsivity and reactive (RA) and proactive (PA) have yet to be fully elucidated. This may be due, in part, to overlapping variance among facets of impulsivity and between RA/PA. The current study systematically examined associations among these variables using both bivariate correlations as well as path analysis. In addition to raw aggression scores, we isolated the variance unique to both RA/PA by regressing RA onto PA (and vice versa), and saving these residual aggression scores. Participants included 384 racially-diverse undergraduates. Results indicated facets of impulsivity uniquely characterize RA/PA, particularly using residual aggression scores. RA was uniquely characterized by higher levels of Negative Urgency followed by low Perseverance, as well as high Premeditation and low Positive Urgency. In contrast, PA was uniquely characterized by higher levels of Positive Urgency, and to a lesser degree, high Premeditation. Results indicate facets of impulsivity represent potentially different underlying pathways to specific subtypes of aggression. As such, impulsivity, particularly in the context of affect, may be especially important to consider in relation to specific subtypes of aggression.     

Rumination and suicidal ideation: The moderating roles of hope and optimism

The current study aimed to investigate whether the correlation between rumination and suicidal ideation is moderated by the presence of hope and optimism. It was hypothesized that both hope and optimism would moderate (weaken) the relationship between rumination and suicidal ideation. Two hundred and ninety-eight participants completed self-report measures of hope, optimism, rumination (brooding and reflection), and depression. Results demonstrated that both hope and optimism weakened the relationship between rumination and suicidal ideation, as well as the relationships between both subscales of rumination and suicidal thinking. These results were found when controlling for symptoms of depression. Results suggest that a ruminative thinking style may be most harmful when an absence of hope or optimism is also present.     

海洛因戒除者的行为冲动性： 基于DDT和IGT任务反应模式的探讨

以61名男性海洛因戒除者和32名正常成年男性为被试,探讨了海洛因戒除者在延迟折扣任务和Iowa赌博任务两种决策条件下的冲动性反应模式及其关系。结果发现,海洛因戒除者的决策行为受其对即时强化的超敏感性或“即时收益优先”模式控制,其高冲动性特质既表现为对强化物长远价值的非敏感性,又表现为对强化物潜在风险的耐受性;该类人群上述两方面的特征虽有一定关联,但二者分别反应了其行为冲动性的两个相对独立的维度,且具有跨戒除时相的相对稳定性     

Ruminative self-focus and autobiographical memory

Many studies have shown a positive relationship between elevated dispositional self-focus and emotional disorder. Trapnell and Campbell (1999) proposed that this relationship was only true for ruminative forms of self-focus, reflective self-focus being associated with psychological health. The present study aimed: (1) to examine the replicability of Trapnell and Campbell's (1999) questionnaire-based differentiation of reflective and ruminative dispositional self-focus; (2) to see whether reflection and rumination could also be differentiated using measures of autobiographical memory; (3) to see whether such memory measures could elucidate mechanisms underlying different forms of dispositional self-focus. 130 volunteers retrieved autobiographical memories to neutral cue words and completed questionnaires. Questionnaires differentiated reflection and rumination: reflection correlated with openness to experience, whereas rumination correlated with neuroticism, replicating previous findings that it is specifically ruminative self-focus that is maladaptive. Memory measures also differentiated reflection and rumination: reflection was unrelated to the affective qualities of memories, whereas rumination correlated with measures of the happiness, unhappiness and at-oneness of memories. Dispositional ruminative self-focus, like neuroticism, was specifically related to increased accessibility of memories of events where individuals felt “not at all at-one with things”. This style of memory access could underpin dispositional ruminative self-focus, which is closely linked to neuroticism.     

Reflections of the student teacher

This paper explores the concept of reflection and its changing role in the journey of the student teacher. It presents part of the findings of a year-long investigation into the reflective practice of student teachers during their training year. Specifically, it investigates the reflections of the student teachers’ lessons during the PGCE (Post/Professional Graduate Certificate of Education) year at a higher education institution (HEI) in England. The strengths and weaknesses of the student teachers’ lessons are analysed and how these reflections change as they reach Newly Qualified Teachers (NQT) status.     

Reflecting and talking about private lives and professional consequences

The section of Part 1 of the Editorial called Arguing for autobiographical reflection and data set out an argument for the use of the sociological imagination where the emphasis is not placed on an aggregated view but on the individual voice. This voice speaks openly of its experience in the situation under examination, in this case, in the educational institution attached to some form of religious tradition. The second part of the Editorial picks up these points made earlier about the qualitative approach and clears the ground, methodologically speaking, for the range of voices in a variety of contexts and autobiographic narratives expressed in the symposium that is Part B. The voices do not speak of unthinking acceptance, of the closed mind and future: their common characteristic is questioning. It is this process that we now examine in itself.     

The concept of reflection: a systematic review and thematic synthesis across professional contexts

Reflection is widely endorsed by professional bodies and practitioners are required to document professional learning to evidence standards of professionalism. Due to the lack of a consensual definition for reflection, there is confusion regarding ‘what reflection is’. Prior to the development of an empirical evidence base that explores reflection, it is important to develop a consensually agreed concept and definition to guide experimental research. The aim of this systematic review is to understand the concept of reflection by performing a synthesis of existing conceptually oriented qualitative studies. Fourteen sources were included in a thematic synthesis that resulted in the construction of four analytical themes: cognitive, integrative, iterative and active. These themes were explored in relation to existing research and a novel definition of reflection was proposed. It is hoped that this review will encourage further enquiry into the concept and process of reflection.
