Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Computer Science

Background:

  • The Sternberg memory test is a widely used cognitive task to assess working memory capacity.
  • Previous implementations of the Sternberg test may lack flexibility in stimulus presentation and noise manipulation.
  • Developing adaptable software tools is crucial for advancing memory research.

Purpose of the Study:

  • To present a versatile software package for the modified Sternberg memory test.
  • To enable the evaluation of subject performance through reaction time analysis.
  • To offer multiple experimental variations within a single program.

Main Methods:

  • A software package developed in Turbo Pascal.
  • Implementation of six distinct versions of the modified Sternberg memory test.
