Trait and State Self-Esteem

Trait and State Self-Esteem

The term self-esteem is often used generically, to refer to how people feel about themselves. However, according to research, there are three distinct constructs that should not be used interchangeably (Brown & Marshall, 2006).

Facial Feedback Hypothesis

Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Area of Science:

Neuroscience
Affective Science
Computational Psychiatry

Background:

Understanding the neural basis of affective states is crucial for treating mood and anxiety disorders.
Affective regulation involves complex temporal dynamics of brain networks.
Electroencephalography (EEG) microstate analysis provides a method to study these dynamics.

Purpose of the Study:

To explore the temporal dynamics of brain networks during self-generated positive and negative affective states.
To identify valence-specific mechanisms of spontaneous affective regulation.
To inform the development of biomarkers for mood and anxiety disorders.

Main Methods:

Utilized EEG microstate analysis.
Investigated temporal dynamics of five distinct microstates.
Compared baseline resting state with self-generated positive and negative affective states.

Main Results:

Noteworthy modulations in microstate dynamics were observed during affective states.
Negative valence states showed increased attention-associated microstates and decreased salience-related microstates.
Positive valence states exhibited more visual/autobiographical memory microstates and fewer auditory/language microstates.

Conclusions:

EEG microstate analysis reveals distinct neurodynamic patterns in affective regulation.
Valence-specific mechanisms of affective regulation were identified.
Findings have implications for developing biomarkers for mood and anxiety disorders.
