Reason and Intuition01:37

Reason and Intuition

5.9K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Introspection01:29

Introspection

Introspection, long upheld as a reliable route to self-knowledge, involves examining one's thoughts, emotions, and mental processes. It underpins many psychological practices, from mindfulness meditation to psychotherapy and self-help strategies. However, empirical evidence challenges the accuracy of introspection as a means of understanding oneself.Limitations of Introspective InsightSeminal work by Nisbett and Wilson demonstrated that individuals are frequently unaware of the true causes...

Borderline Personality Disorder is a complex and multifaceted mental health condition characterized by pervasive instability in interpersonal relationships, self-image, emotions, and impulse control. This instability manifests in extreme emotional reactions, fear of abandonment, and self-destructive behaviors. The disorder significantly impacts daily functioning, often leading to distress in both personal and professional domains.

Bullying

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Psychological and Sociocultural Causes of Schizophrenia

969
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Stress and Mental Health01:30

Stress and Mental Health

1.7K
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
Individuals with depression often experience challenges in both their personal and professional...

Area of Science:

  • Psychiatry
  • Psychology
  • Behavioral Science

Background:

  • Suicidal behavior is commonly believed to be impulsive.
  • This study challenges the notion that suicidal behavior is primarily impulsive.

Purpose of the Study:

  • To investigate the association between trait impulsivity and suicidal behavior.
  • To critically review the impulsivity of specific suicide attempts.
  • To propose a model where painful and fearsome behaviors mediate suicidal behavior in impulsive individuals.

Main Methods:

  • Conducted a meta-analysis on trait impulsivity and suicidal behavior.
  • Performed a critical review of research on the impulsivity of specific suicide attempts.

Main Results:

  • The meta-analysis revealed a small association between trait impulsivity and suicidal behavior.
  • Studies examining the mediating role of painful and provocative behaviors supported the proposed model.
  • Current research struggles to adequately measure the impulsivity of specific suicide attempts.

Conclusions:

  • Suicidal behavior is rarely impulsive and often involves forethought.
  • Painful and fearsome behaviors may enhance suicidal capacity in impulsive individuals.
  • Development of measures sensitive to episodic planning is crucial for future research.
