Summary
The study found that Stimulus-Response Compatibility and Hand Position interact, meaning their effects are not independent. This interaction explains why certain experimental outcomes occur, aligning with Simon
Area of Science:
- Cognitive Psychology
- Human Factors Research
Background:
- The Simon, Hinrich, and Craft (1970) experiments investigated factors influencing performance.
- Stimulus-Response Compatibility (SRC) effects are typically explained by stimulus-response similarity.
Purpose of the Study:
- To explain the non-additive effects of Stimulus-Response Compatibility and Hand Position.
- To propose a model accounting for the interaction between SRC and hand position.
Main Methods:
- Manipulation of two factors: Stimulus-Response Compatibility and Position of Hands.
- Analysis of the interaction effects between these two factors.
Main Results:
- The effects of Stimulus-Response Compatibility and Hand Position were found to be non-additive.
- Two automatic responses are triggered by stimuli, leading to two Stimulus-automatic Response mappings.
- These mappings can be positively or negatively correlated based on experimental conditions.
Conclusions:
- The proposed model, based on correlated automatic response mappings, successfully predicts experimental data.
- The interaction between Stimulus-Response Compatibility and Hand Position explains the observed non-additive effects.
