The Influence of Cognition on Affect01:29

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 interpreted as...

科学领域:

  • 数字表型化
  • 神经科学
  • 精神病学

背景情况:

  • 情绪障碍 (如抑郁症和双相情绪障碍) 会导致影响日常生活的认知障碍.
  • 需要客观,被动地监测MD的认知功能,以便更好地管理.
  • 智能手机打字动态为这种监控提供了潜在的途径.

研究的目的:

  • 研究智能手机打字动态对MD患者认知功能的预测能力.
  • 评估被动打字数据是否可以预测认知表现.
  • 通过MD和健康对照来比较打字动态和认知之间的关系.

主要方法:

  • 127名参与者使用BiAffect键盘约28天,收集输入元数据.
  • 进行了两次神经心理评估,间隔至少14天.
  • 主要组件分析和结构方程建模用于分析类型特征和预测认知测试性能.

主要成果:

  • 较慢的打字速度预测了健康对照者的认知表现较差,但这种关系在MD患者中较弱或更可变.
  • 在MD和健康对照组中,按键动态同样预测了Trail-Making测试B部分的性能.
  • 根据认知测试和参与者组,输入速度和其他按键动态显示出不同的预测实用性.

结论:

  • 按键动态是评估认知功能的生态有效,被动的方法.
  • 作为认知生物标志物的类型动态的实用性在不同认知领域和人群中有所不同.
  • 需要进一步的研究来完善数字表型化在心理健康方面的认知评估.
