Social Cognitive Perspective on Personality01:30

Social Cognitive Perspective on Personality

1.0K
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
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...

Magnetic Declination01:19

Magnetic Declination

495
Magnetic declination is the angle between true north, which aligns with the Earth's rotational axis, and magnetic north, which follows the direction of the Earth's magnetic field. This discrepancy exists because the magnetic poles do not coincide with the geographic poles. The value of magnetic declination depends on the observer's location on Earth and is subject to changes over time due to the dynamic nature of the Earth's magnetic field.The declination is called eastern when magnetic north...

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Summary

Personality and cognition remained stable in multiple sclerosis (MS) patients over five years. However, declines in Extraversion and Conscientiousness were linked to cognitive deterioration in the MS population.

Area of Science:

  • Neuroscience
  • Psychology

Background:

  • Previous research indicated stable personality and cognition in multiple sclerosis (MS) patients over three years.
  • Longer-term studies are needed to identify potential emerging personality dysfunction in MS.

Purpose of the Study:

  • To investigate personality and cognitive changes in multiple sclerosis patients over a five-year period.
  • To determine if cognitive decline is associated with specific personality trait changes in MS.

Main Methods:

  • Utilized the NEO Five-Factor Inventory for personality assessment and the Brief International Cognitive Assessment for MS for cognitive evaluation.
  • Classified patients into "Cog Stable" and "Cog Decline" groups based on cognitive changes over five years.

Main Results:

  • Across all participants, Extraversion and Conscientiousness showed a decline over the five-year study period.
  • The "Cog Decline" group exhibited a more pronounced decrease in Extraversion and Conscientiousness compared to the "Cog Stable" group.
  • These findings demonstrate a significant association between personality changes and cognitive deterioration in multiple sclerosis.

Conclusions:

  • While personality may show stability in the short term for MS patients, longer durations reveal declines in specific traits.
  • Cognitive decline in multiple sclerosis is demonstrably linked to changes in personality, particularly Extraversion and Conscientiousness.
