Cognitive Dissonance01:38

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
Beck's Cognitive Therapy01:25

Beck's Cognitive Therapy

Cognitive therapy is a psychological approach designed to address distortions in thinking, which can lead to negative emotions and unrealistic beliefs. These cognitive distortions often influence how individuals interpret and respond to situations, exacerbating emotional distress. Below are some prevalent cognitive distortions, their characteristics, and examples of how they manifest in thought processes.

Dissociative Disorders01:27

Dissociative Disorders

Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

A hallmark feature of dissociative disorders is the dissociative fugue...
Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events, are a...
Fundamental Attribution Error01:14

Fundamental Attribution Error

According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is called the fundamental attribution...
Interference and Decay01:16

Interference and Decay

Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Summary

Natural disasters like earthquakes can disrupt cognitive function. This study found that greater self-reported cognitive disruption after the Christchurch earthquake correlated with more errors on a sustained attention task.

Area of Science:

  • Cognitive Psychology
  • Trauma Studies
  • Neuroscience

Background:

  • Natural disasters are known to increase stress and cognitive intrusions.
  • Previous research has not adequately assessed the impact of disaster-induced cognitive disruption on human performance.
  • Understanding cognitive impacts is crucial for post-disaster recovery.

Purpose of the Study:

  • To investigate the impact of the 2010 Christchurch earthquake on cognitive disruption.
  • To examine the relationship between self-reported cognitive disruption and performance on the Sustained Attention to Response Task (SART).
  • To determine if cognitive disruption affects performance independently of anxiety, depression, or sleep.

Main Methods:

  • Assessed self-reported earthquake-induced cognitive disruption.
  • Measured performance on the Sustained Attention to Response Task (SART).
  • Utilized correlational analysis, controlling for anxiety, depression, sex, and sleep.

Main Results:

  • A strong positive correlation was found between self-reported cognitive disruption and errors of commission on the SART (r=.80, p<.001).
  • This relationship remained significant even after controlling for potential confounding factors.
  • Cognitive disruption directly impacted sustained attention performance.

Conclusions:

  • Cognitive disruption following natural disasters significantly impairs human performance.
  • Post-disaster assessments should include cognitive self-regulation and conscious thought processes.
  • Beyond clinical measures like anxiety and depression, cognitive impacts are critical for understanding disaster effects.
