Hyperactivity in Children: A Focus on Genetic Research and Psychological Theories

Hyperactivity has attracted a large amount of research interest in recent years. Here we review developments in genetic research and in research testing psychological theories of the condition. Family, adoptee and twin studies indicate a strong role for genetic factors in the etiology of hyperactivity. Evidence is emerging also from molecular genetic studies, implicating specific genes that may be involved. At the level of cognitive functioning, a divided, focused or sustained attention deficit does not seem to be a core deficit in hyperactivity. Although children with hyperactivity often perform poorly on certain executive function tasks, there is disagreement about the interpretation of these findings. The association reported in some studies between a slow inhibitory process and hyperactivity may reflect a generally slow, variable in speed and inaccurate pattern of responding. Hypotheses about psychological mechanisms such as state regulation or delay aversion provide alternative, and particularly encouraging, interpretations of the findings. We discuss the possible integration of the two lines of research—those of genetic research and research on psychological mechanisms.     

外倾和神经质对情绪的影响

采用心理生理实验法和问卷法检验人格特质对情绪的影响。结果：高外倾的正情绪增强型调节多,正情绪也多;高神经质的负情绪增强型调节多,负情绪也多。厌恶情绪过程中,外倾的R-R间期增加大,躯体活动变化弱,快乐增加大,兴趣增加少;神经质的FT增加大,恐惧增强多。调节过程中,高外倾的FT增加大;神经质的FT增加弱,表情行为强度增强大。结论：外倾和神经质对厌恶情绪及其调节过程的情绪成分变化起复杂作用,配合其调节方式习惯,使各特质具有特别的情绪特点。     

激活右腹外侧前额叶提高抑郁症患者对社会疼痛的情绪调节能力：一项TMS研究

负性人际交往经历和负性社会事件是抑郁症的重要诱导因素, 而社会功能受损是抑郁症患者的重要特征之一, 患者通常表现出对社会疼痛的情绪失调。为了提高抑郁症患者在负性社交情境中或面对负性社会事件时的情绪调节能力, 本研究采用经颅磁刺激技术(transcranial magnetic stimulation, TMS), 考察抑郁症患者在腹外侧前额叶(the ventrolateral prefrontal cortex, VLPFC)被激活后其情绪调节能力的改变。结果表明, 当右侧VLPFC被TMS激活且患者采用认知重评策略调节情绪时, 实验组患者(n = 64)比对照组患者(n = 63)在社会排斥情境下报告了更弱的负性情绪体验, 这说明激活右侧VLPFC可以有效提高患者对社会疼痛的外显性情绪调节能力。本研究是采用TMS提高抑郁症患者情绪调节能力的首次尝试, 实验发现不但支持了VLPFC与认知重评策略的因果关系, 还为临床改善抑郁症等社会功能障碍患者的情绪调节能力提供了明确的神经治疗靶点。后续研究还需探讨多疗程TMS刺激方案、改变社会疼痛的诱发方式、对比左右侧VLPFC的治疗效果、尝试使用其他的情绪调节策略, 进一步验证本研究的结论, 优化TMS治疗方案。     

负性情绪对选择性注意抑制的影响及其调节——基于女大学生黄体期的研究

采用空间提示任务,研究经期不同时段女大学生负性情绪对选择性注意抑制的影响及有效的情绪调节策略。实验1选取黄体中后期与月经期女大学生各32名,使用视频材料诱发中性和负性情绪,结果发现黄体中后期被试选择性注意抑制能力显著低于月经期;实验2选取104名黄体中后期的女大学生,负性情绪诱发后分组采用沉思、分心与人际策略进行调节,结果表明三种策略均降低了个体负性情绪,提高了选择性注意抑制成绩。研究结论如下:黄体中后期女性更受负性情绪影响,注意抑制能力下降,但有效的调节策略可改善其负性情绪并提高注意抑制能力。     

Self‐reported inner speech use in university students

Remarkably little is known regarding what people talk to themselves about (inner speech use) in their everyday lives. Existing self‐directed speech measures (e.g., thought sampling and questionnaires) either uniquely capture inner speech frequency and neglect its content or classify self‐reported thoughts instances in overly simplistic categories determined by the researchers. In the current study, we describe an open‐format thought listing procedure as well as a refined coding scheme and present detailed inner speech content self‐generated by 76 university students. The most frequently self‐reported inner speech activities were self‐regulation (e.g., planning and problem solving), self‐reflection (e.g., emotions, self‐motivation, appearance, behavior/performance, and autobiography), critical thinking (e.g., evaluating, judging, and criticizing), people in general, education, and current events. Inner speech occurred most commonly while studying and driving. These results are consistent with the self‐regulatory and self‐referential functions of inner speech often emphasized in the literature. Future research avenues using the open‐format inner speech listing procedure and coding scheme are proposed.     

Individual differences in cognitive control processes and their relationship to emotion regulation

Cognitive control and emotional control share many similarities, but the specific relationship between these processes is not well understood. This study explored the relationship between three types of cognitive control (working memory updating, response inhibition and set-shifting) and two emotional regulation strategies (expressive suppression and cognitive reappraisal). Corrugator electromyography, behaviour and self-reports of affect were measured as indices of emotion regulation. Results indicate that working memory updating predicted negative affect reduction during reappraisal and during expressive suppression. This study specifically shows that the working memory component of cognitive control is associated with negative affect reduction. Response inhibition and set-shifting were not specifically related to negative affect reduction, but these variables did predict aspects of emotional behaviour and regulation. These results suggest a general role for cognitive control in some aspects of emotion regulation as well as a specific modulatory role for working memory updating in the regulation of negative affect.     

Psychometric properties of a measure of psychological factors among francophone adolescent learners in a South African setting

This study reported on the psychometric properties of a prospective measure of psychological wellbeing among immigrant francophone adolescent learners in high schools in the Western Cape, South Africa. The sample size comprised 170 participants (females = 51%; age range 14 to 20 years). Scores from the measure were analysed for internal consistency and factorial structure. The evidence suggests scores from the measure to be reliable for measuring emotional regulation, aggressiveness, empathy, and sympathy among the immigrant francophone adolescent learners.     

An examination of the roles of trauma exposure and posttraumatic stress disorder on emotion regulation strategies of Operation Iraqi Freedom,Operation Enduring Freedom,and Operation New Dawn veterans

Theories of posttraumatic stress disorder (PTSD) implicate emotional processes, including difficulties utilizing adaptive emotion regulation strategies, as critical to the etiology and maintenance of PTSD. Operation Iraqi Freedom, Operation Enduring Freedom, and Operation New Dawn (OIF/OEF/OND) veterans report high levels of combat exposure and PTSD. We aimed to extend findings suggesting that emotion regulation difficulties are a function of PTSD, rather than combat trauma exposure or common comorbidities, to OIF/OEF/OND veterans, in order to inform models of PTSD risk and recovery that can be applied to returning veterans. We tested differences in emotion regulation, measured with the Difficulties in Emotion Regulation Scale and Emotion Regulation Questionnaire, among trauma-exposed veterans with (n = 24) or without PTSD (n = 22) and healthy civilian comparison participants (n = 27) using multivariate analyses of covariance, adjusting for major depressive disorder, anxiety disorders, and demographic variables (age, sex, and ethnicity). Veterans with PTSD reported more use of expressive suppression and more difficulties with emotion regulation than veterans without PTSD and healthy comparison participants. Groups did not differ on cognitive reappraisal. Findings suggest the key role of PTSD above and beyond trauma exposure, depression, and anxiety in specific aspects of emotion dysregulation among OIF/OEF/OND veterans. Interventions that help veterans expand and diversify their emotion regulation skills may serve as helpful adjunctive treatments for PTSD among OIF/OEF/OND veterans.     

Cognitive Appraisal as a Predictor of Cognitive Emotion Regulation Choice

More attention has recently been focused on how a person may choose their emotion regulation strategies depending on the situation. The present research examined how people cognitively appraised a situation that they had actually encountered in their life and how this appraisal affected their subsequent cognitive emotion regulation strategies. Three hundred and twenty‐four participants were instructed to recall the most stressful situation in the last month, and to rate how they cognitively appraised the situation (threat, centrality, controllability, commitment, injustice/unfairness, expectedness, expectancy) and how they cognitively regulated their emotion (self‐blame, blaming others, acceptance, refocus on planning, positive refocusing, rumination, positive reappraisal, putting into perspective, catastrophizing). Multiple regression analysis revealed that even after control for other variables, such as age, sex, personality, the time when the situation occurred and the intensity of negative emotion, all criteria of cognitive appraisal except for expectedness predicted cognitive emotion regulation choice. Implications and limitations of this research are discussed.
