Negative and Cognitive Symptoms of Schizophrenia01:30

Negative and Cognitive Symptoms of Schizophrenia

1.1K
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Language and Cognition

881
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Causes of Social Behavior II: Cognitive Processes

301
Cognitive processes affect social behavior by guiding how individuals perceive, interpret, and respond to social stimuli. These mental processes enable individuals to assess others' behaviors, attribute causes to their actions, and form expectations based on past experiences.Causes of Behavior and Social JudgmentsIndividuals determine the causes of others' behaviors by distinguishing between personal traits and external circumstances. For example, if a friend frequently arrives late, an...

Environmental Influences on Intelligence

1.2K
Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...

Cognitive Dissonance01:38

Cognitive Dissonance

29.1K
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...

Cognitivism

2.9K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Summary

Poverty worries may affect cognitive function in all income levels, not just the poor. Reanalysis suggests previous findings might be due to testing limitations rather than income itself.

Area of Science:

  • Cognitive Psychology
  • Socioeconomic Studies
  • Behavioral Economics

Background:

  • Previous research suggested poverty-related worries impair cognitive functioning.
  • Mani et al. presented laboratory experiments supporting this hypothesis.

Purpose of the Study:

  • To reanalyze the findings of Mani et al. regarding poverty worries and cognitive function.
  • To investigate the influence of income and financial worries on cognitive performance without dichotomization.

Main Methods:

  • Reanalysis of existing experimental data without dichotomizing income levels.
  • Examination of potential spurious interactions between income and experimental manipulation.
  • Assessment of ceiling effects in cognitive tests.

Main Results:

  • The reanalysis failed to corroborate the original findings.
  • Spurious interactions were identified, likely due to ceiling effects from short, easy tests.
  • The cognitive impact of financial worries may extend beyond impoverished populations.

Conclusions:

  • The original conclusion that poverty worries specifically impede cognitive functioning in the poor is not supported by this reanalysis.
  • Financial worries might have broader implications for cognitive function across different socioeconomic strata.
  • Methodological considerations, such as test design, are crucial in studies examining socioeconomic factors and cognition.
