- 微分診断のためのバイオマーカーとしてのRewPの可能性を評価する.
主な方法:
- うつ病や恐怖症の病理学的特徴を調べた
- これらの特性の指数との報酬ポジティビティ (RewP) の関連性を分析した.
- ネガティブ・エフェクティビティ (NA) のような共有要因を特定するために,共有変数と構造方程式モデリングを制御するために回帰モデリングを使用した.
主要な成果:
- RewPとうつ病と恐怖症の特徴の間の相反的な関連性が見つかりました
- これらの相反する関係は,共有の差を制御した後に強化された.

01:14Avoidance Learning and Learned Helplessness
1.9K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

01:29Personality Theory by Eysenck and Eysenck
655
Hans and Sybil Eysenck developed a widely recognized theory of personality, which emphasizes the role of temperament and genetically based differences in shaping individual traits. Their theory posits that biological factors primarily determine personality and can be understood through two main dimensions: extroversion/introversion and neuroticism/stability.
In the extroversion/introversion dimension, highly extroverted people are sociable, outgoing, and easily connect with others. In contrast,...
