- 心理学 心理学 心理学
- 附着理论 附着理论
背景情况:
- 无组织的依恋 (DA) 与自主兴奋和大脑连接的失调有关.
- 很少有研究使用脑电图 (EEG) 来调查DA背后的特定神经变化.
研究的目的:
- 在成人附着面试 (AAI) 之前和之后,在一个非临床样本中调查EEG微态参数,以无组织的附着 (DA).
- 探索DA患者与情绪处理和心态化相关的大脑活动的潜在差异.
主要方法:
- 在AAI之前和之后,对50名参与者进行了两次闭眼休息状态 (RS) EEG记录.
- 使用Cartool软件分析了EEG微态参数 (平均持续时间,时间覆盖率,发生率).

03:34Theory of Romantic Attachment in Adulthood

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.

Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that...

01:14Piaget's Stage 1 of Cognitive Development
623
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

02:30Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

110
Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...

01:29Personality Theory by Eysenck and Eysenck
460
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,...
