Cognitive Dissonance01:38

Cognitive Dissonance

36.8K
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...

Social Cognitive Perspective on Personality01:30

Social Cognitive Perspective on Personality

994
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...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

391
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Virtual Work

The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

Personal Identity01:25

Personal Identity

322
Personal identity is the deeply felt sense of self that individuals cultivate over time, intricately woven from intrinsic qualities they consider essential to their existence—qualities such as morality, intelligence, and friendliness. These attributes serve as vital internal benchmarks, guiding individuals in evaluating whether their actions resonate with their true selves.When personal identity takes center stage in one's life, individuals often emphasize their distinctiveness,...

Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

1.5K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Area of Science:

  • Gerontology and Cognitive Science
  • Digital Health and Medical Technology

Background:

  • Global rise in dementia prevalence necessitates improved cognitive screening methods.
  • Traditional tools often focus narrowly on memory, neglecting other cognitive domains.
  • Virtual reality (VR) presents a potential, yet under-researched, screening modality for cognitive function.

Purpose of the Study:

  • To evaluate the feasibility and acceptability of a VR-based cognitive screening tool in a primary care setting for older adults.
  • To determine the VR module's efficacy in differentiating between cognitively intact and impaired individuals.

Main Methods:

  • A comparative study involved 60 participants (aged 65-85) in Singapore, categorized by Montreal Cognitive Assessment (MoCA) scores.
  • Participants completed a VR module assessing learning, memory, perceptual-motor, and executive functions.
  • Feasibility and acceptability were assessed via performance scores and a user-feedback questionnaire.

Main Results:

  • The VR tool was feasible, with completion times averaging around 20 minutes.
  • Participants reported positive perceptions and attitudes towards VR (mean scores 3.80-4.48/5).
  • VR performance scores significantly differentiated between cognitively intact and impaired groups (P<.001) and correlated with other cognitive tests (MoCA: 0.427).

Conclusions:

  • A VR-based cognitive screening tool is feasible and acceptable for older adults in primary care.
  • The VR tool demonstrated effectiveness in discriminating cognitive impairment.
