Trait and State Self-Esteem

11.5K
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).

Polygenic Traits

69.1K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Attachment Styles01:24

Attachment Styles

442
Jeffrey Simpson's attachment theory suggests that early caregiver relationships shape lasting patterns of behavior and emotional regulation, known as attachment styles. These patterns are organized along two key dimensions: self-esteem and interpersonal trust. The intersection of these dimensions produces four primary attachment styles that typically persist throughout life and significantly influence how individuals form and maintain relationships.Secure Attachment StyleIndividuals with a...

Parenting Styles

Diana Baumrind's four parenting styles — authoritarian, authoritative, neglectful, and permissive — each influence children's socio-emotional development differently.
Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
Authoritative...

Traits and States

560
Personality traits represent consistent patterns in behavior, thoughts, and emotions, reflecting an individual's tendencies across various situations. For example, extraversion, a well-known trait, manifests in individuals as talkative, energetic, and enthusiastic behaviors. These traits are stable over time, offering a reliable framework for predicting how people might act in different contexts. However, they do not define every moment of an individual's life. In contrast to traits,...

Area of Science:

  • Cognitive Neuroscience
  • Psychology
  • Neuroimaging

Background:

  • Anecdotal evidence suggests individual differences in problem-solving strategies, specifically insight versus analytical thought.
  • The existence of stable, trait-like differences in cognitive styles and their neural underpinnings remains largely unexplored.

Purpose of the Study:

  • To investigate the existence of stable individual differences in cognitive styles, specifically the tendency towards insight versus analytical problem-solving.
  • To determine if these cognitive style differences are associated with trait-like variations in resting-state brain activity.
  • To explore the predictive power of resting-state brain activity on problem-solving strategies.

Main Methods:

  • Recorded resting-state electroencephalograms (RS-EEGs) from participants on four separate occasions over seven weeks.
  • Assessed participants' problem-solving strategies using anagrams and compound remote associates problems, solvable by either insight or analysis.
  • Analyzed the relationship between resting-state brain activity patterns and consistent problem-solving approaches.

Main Results:

  • Individual tendencies to solve problems via insight or analysis were consistent across tasks and time.
  • Trait-like differences in resting-state brain activity, including frontal-posterior activity balance and temporal-lobe hemispheric asymmetries, were identified.
  • These brain activity patterns predicted individual problem-solving strategies weeks in advance.

Conclusions:

  • A stable insight-analytic dimension of cognitive style exists and is predictable from resting-state brain activity.
  • Resting-state brain activity provides a neural basis for individual differences in cognitive styles.
  • This research opens new avenues for neuroscience-based intellectual, educational, and vocational assessments.
