Area of Science:

  • Psychology
  • Psychophysiology
  • Behavioral Science

Background:

  • Implementing complex psychological and psychophysiological experiments requires specialized software.
  • Existing tools may lack flexibility in stimulus presentation and response recording.
  • Accurate data collection is crucial for reliable experimental outcomes.

Purpose of the Study:

  • To introduce Affect 4.0, a novel software package designed for psychological and psychophysiological research.
  • To highlight the software's capabilities in presenting diverse stimuli and recording precise behavioral data.
  • To provide researchers with a free, user-friendly tool for experimental design and execution.

Main Methods:

  • Affect 4.0 software was developed for presenting visual, acoustic, and tactile stimuli.
  • The software supports complex stimulus sequencing, including semirandomized and response-contingent designs.
  • Response latencies and analog behavioral input are registered with millisecond accuracy.

Main Results:

  • Affect 4.0 enables the creation of intricate experimental paradigms.
  • The software achieves high temporal precision in stimulus delivery and response measurement.
  • User-friendliness was a key design consideration, facilitating implementation.

Conclusions:

  • Affect 4.0 offers a robust and accessible solution for conducting advanced psychological and psychophysiological research.
  • The software's capabilities in stimulus control and data acquisition can enhance experimental research.
  • Availability free of charge lowers the barrier to entry for researchers.
