ABSTRACT— Processes of selective attention and emotion operate together in prioritizing thoughts and actions. Abundant evidence suggests that emotionally salient stimuli and affective states can determine how visual attention is allocated. However, the brain regions mediating the effects of attention and emotion include shared and reciprocally connected structures. This raises an intriguing question about a reciprocal effect: Does attention also influence emotional responses? Here we review a series of studies that show that indeed it does. The results indicate that attention has a negative affective impact for otherwise neutral visual stimuli (abstract patterns and unfamiliar faces) that must be ignored or otherwise inhibited during the performance of a task. Finding that selective attention has distinct affective consequences for visual stimuli represents a new, fundamental discovery about the relation between the two main systems of prioritization in the human brain. 相似文献

ABSTRACT— Newly licensed drivers are disproportionally involved in fatal crashes, and there is evidence that failure to attend to potentially relevant information is a major contributor to this problem. Corroborating this, in controlled scenarios on a driving simulator, we have found that younger drivers attend to (i.e., fixate) target regions in the virtual world that contain information about potential risks much less frequently than do more experienced drivers. We have developed a PC-based training program that substantially improves younger drivers' attention to these regions in the driving simulator and have recently replicated these training results on the road in a real driving situation. 相似文献

Research on early childhood predictors of violent behaviors in early adulthood is limited. The current study investigated whether individual, family, and community risk factors from 18 to 42 months of age were predictive of violent criminal arrests during late adolescence and early adulthood using a sample of 310 low-income male participants living in an urban community. In addition, differences in trajectories of overt conduct problems (CP), hyperactivity/attention problems (HAP), and co-occurring patterns of CP and HAP from age 1½ to 10 years were investigated in regard to their relationship to violent and nonviolent behaviors, depression, and anxiety at age 20. Results of multivariate analyses indicated that early childhood family income, home environment, emotion regulation, oppositional behavior, and minority status were all significant in distinguishing violent offending boys from those with no criminal records. In addition, trajectories of early childhood CP, but not attention deficit hyperactivity disorder, were significantly related to self-reports of violent behavior, depressive symptoms, and anxiety symptoms. Implications for the prevention of early childhood risk factors associated with adolescent and adult violent behavior for males are discussed. 相似文献

正念训练是指个体将注意力集中于当下体验的一种心理干预方法。先前研究表明正念训练可以促进其注意力、执行功能、情绪调节等的发展, 而正念训练对幼儿心理发展的作用机制并不清楚。因此, 为了考察正念训练对3~4岁幼儿注意力和执行功能的影响。采用前后测设计, 对正念组进行每周2次, 每次20~30分钟, 共12次的正念训练; 对照组不进行任何训练。结果发现:(1) 在注意力方面, 正念组与对照组前测差异不显著, 训练后正念组幼儿持续性注意力得分显著高于对照组。(2) 在执行功能方面, 正念组和实验组在抑制控制、认知灵活性以及工作记忆上前测得分差异不显著, 训练后正念组幼儿抑制控制和认知灵活性得分显著优于对照组, 而两组幼儿工作记忆差异不显著。研究表明, 正念训练促进了3~4岁幼儿注意力和执行功能的发展, 且在执行功能方面主要表现为对抑制控制和认知灵活性的提升。 相似文献

基于外源性线索-靶子范式, 采用2(线索-靶子间隔时间, stimulus onset asynchronies, SOA:400~600 ms、1000~1200 ms) × 3(目标刺激类型:视觉、听觉、视听觉) × 2(线索有效性:有效线索、无效线索)的被试内实验设计, 要求被试对目标刺激完成检测任务, 以考察视觉线索诱发的返回抑制(inhibition of return, IOR)对视听觉整合的调节作用, 从而为感知觉敏感度、空间不确定性及感觉通道间信号强度差异假说提供实验证据。结果发现:(1) 随SOA增长, 视觉IOR效应显著降低, 视听觉整合效应显著增强; (2) 短SOA (400~600 ms)时, 有效线索位置上的视听觉整合效应显著小于无效线索位置, 但长SOA (1000~1200 ms)时, 有效与无效线索位置上的视听觉整合效应并无显著差异。结果表明, 在不同SOA条件下, 视觉IOR对视听觉整合的调节作用产生变化, 当前结果支持感觉通道间信号强度差异假说。 相似文献

通过两个眼动实验考察金钱奖励和惩罚引起的动机对个体在不同空间线索条件下注意控制加工的影响。实验1采用朝向/反向眼跳范式, 被试通过内源性线索提供心理准备的情况下做出简单的朝向眼跳以及需要抑制优势反应的反向眼跳。结果发现, 相比无奖惩条件, 奖励条件下朝向眼跳任务的正确率更高, 惩罚条件下反向眼跳任务的正确率更高; 两种眼跳任务中有奖惩条件下的眼跳峰速度均比无奖惩条件高。实验2采用Go/No-go任务, 进一步探讨了由副中央凹加工外源性边缘线索从而不能提供充分心理准备的情况下奖励和惩罚对注意控制的影响。结果发现, 奖励条件下Go反应的眼跳潜伏期更短, 惩罚条件下No-go反应正确率更高, 眼跳峰速度在两种条件下均比无奖惩条件高。以上结果表明, 奖励和惩罚均能够促进个体的注意控制, 但二者的加工过程是分离的, 奖励能够改善趋近行为, 惩罚则能够显著促进抑制控制行为, 且奖励和惩罚在注意控制加工过程中具有不同的作用模式, 奖励能够更早唤醒注意控制系统从而更快地促进行为的发生与执行, 惩罚则能够通过调节注意资源促进以目标为导向的行为中对优势反应的抑制。 相似文献

We tested the response dynamics of the evaluative priming effect (i.e. facilitation of target responses following evaluatively congruent compared with evaluatively incongruent primes) using a mouse tracking procedure that records hand movements during the execution of categorisation tasks. In Experiment 1, when participants performed the evaluative categorisation task but not the non-evaluative semantic categorisation task, their mouse trajectories for evaluatively incongruent trials curved more toward the opposite response than those for evaluatively congruent trials, indicating the emergence of evaluative priming effects based on response competition. In Experiment 2, implementing a task-switching procedure in which evaluative and non-evaluative categorisation tasks were intermixed, we obtained reliable evaluative priming effects in the non-evaluative semantic categorisation task as well as in the evaluative categorisation task when participants assigned attention to the evaluative stimulus dimension. Analyses of hand movements revealed that the evaluative priming effects in the evaluative categorisation task were reflected in the mouse trajectories, while evaluative priming effects in the non-evaluative categorisation tasks were reflected in initiation times (i.e. the time elapsed between target onset and first mouse movement). Based on these findings, we discuss the methodological benefits of the mouse tracking procedure and the underlying processes of evaluative priming effects. 相似文献

依据交流语境特征创设了语言交流、共享对象的语言交流、共享对象和表情的语言交流,通过交流范式探查:交流语境对学习过程中学习者语言选择性注意的影响。结果显示:(1)语言交流条件下语言选择性注意整体水平最高;不同语境下选择性注意整体水平随交流时间进程而增高。(2)语言交流条件下语言选择性注意指向性水平最高;共享对象和表情条件最低,但集中性水平最高;总体上,指向性和集中性水平随学习进程相对稳定增高,但语言交流条件与共享对象条件下学习阶段1的集中性水平显著高于中间学习阶段。结果发现:交流语境不同时,不同非语言因素对于语言认知加工产生的影响作用不同;交流双方认知的协调过程同时受到语言和非语言因素的共同作用。概言之,非语言因素降低了语言选择性注意的整体水平和指向性水平;但表情因素提高了集中性水平。 相似文献
