Working Memory01:24

Working Memory

399
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Measures of Intelligence

7.7K
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Human-Computer Interaction

Background:

  • The N-Back task is a standard measure of working memory.
  • Assessing working memory is crucial for understanding cognitive function.
  • Gamified approaches can enhance engagement in cognitive tasks.

Purpose of the Study:

  • To introduce TAG-ME Again, a serious game designed to assess working memory.
  • To evaluate the convergent validity of TAG-ME Again with the established N-Back task.
  • To explore the reliability of a gamified working memory assessment tool.

Main Methods:

  • Two experiments were conducted to assess convergent validity.
  • Experiment 1 involved 31 adults correlating game performance with N-Back task measures (reaction time, accuracy).
  • Experiment 2 involved 66 university students with equated stimulus-response mappings and spatial demands between game and task.

Main Results:

  • Significant correlations were found between TAG-ME Again and the N-Back task across both experiments.
  • The strongest correlations were observed for the more difficult 3-Back condition.
  • Equating task parameters in Experiment 2 yielded significant correlations for 2-Back and 3-Back levels.

Conclusions:

  • TAG-ME Again demonstrates convergent validity with the N-Back task.
  • The serious game is a reliable and potentially more engaging tool for assessing working memory.
  • Gamification can be effectively applied to cognitive assessment tools.
