Summary
Asking about video game habits before cognitive tasks benefits gamers but hinders non-gamers, potentially biasing study results on gaming and cognitive performance.
Area of Science:
- Cognitive Psychology
- Human-Computer Interaction
- Experimental Psychology
Background:
- Video game research often involves questionnaires about playing habits.
- The timing of these questionnaires in relation to cognitive tasks is not well understood.
- Potential for expectancy effects to influence task performance.
Purpose of the Study:
- To investigate if questionnaire timing (before vs. after tasks) impacts gamer and non-gamer performance.
- To determine if this timing influences cognitive-motor task outcomes.
- To identify potential biases in video game research.
Main Methods:
- 131 participants (gamers and non-gamers) completed cognitive-motor tasks (choice-RT, Simon, task-switching, digit span).
- Participants answered a video game habits questionnaire either before or after task performance.
- Performance metrics included reaction times and accuracy.
Main Results:
- Gamers showed faster reaction times in the Simon task when the questionnaire was administered before tasks.
- Non-gamers exhibited slower reaction times in the Simon and task-switching tasks when the questionnaire was administered before tasks.
- These findings suggest a response expectancy effect influenced by questionnaire timing.
Conclusions:
- Administering video game questionnaires before cognitive tasks can create expectancy effects.
- These effects can positively impact gamers and negatively impact non-gamers.
- Researchers should consider questionnaire timing to avoid biasing studies on video games and cognitive performance.
