背景情况:

关于病态认知障碍如何影响情绪反应抑制的研究有限.
老龄化会影响情绪反应的抑制,但它与认知衰退的相互作用还未得到充分研究.
轻度认知障碍 (MCI) 是痴呆症的临床前阶段,对理解认知和情绪调节变化至关重要.

研究的目的:

研究情绪对轻度认知障碍 (MCI) 患者反应抑制的影响.
检查是否双重竞争框架,考虑到有限的认知资源,解释了MCI中的情绪反应抑制联系.
为了确定MCI中响应抑制的神经相关的特定情绪影响.

主要方法:

利用两个不同的情绪停止信号任务来评估反应抑制.
在患有MCI的个体和潜在的对照组 (隐含) 之间比较表现.
分析了电生理学测量 (N2和P3延迟) 和行为结果 (准确性,反应时间).

主要成果:

负面情绪显著延长了N2延迟时间,表明认知处理延迟.

Blind Procedures

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Social Facilitation

Social Facilitation

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Factors Affecting Perception

Factors Affecting Perception

Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Lazarus's Cognitive Appraisal Theory

Lazarus's Cognitive Appraisal Theory

Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...

The Influence of Affect on Cognition

The Influence of Affect on Cognition

Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

The Influence of Cognition on Affect

The Influence of Cognition on Affect

Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...
