S1-1 Translation and Response Selection (2)

Sensorimotor Transformations in Response Selection

Topics:

• S-R Compatibility and Cognitive Translation

• Cognitive and Spatial Coding in Response Selection

Readings:

• Chen J & Proctor RW (2012) on directional compatibility.

• Lee S et al. (2016) on control-display alignment.

Core Components:

1. Sensory System: Receives environmental/body info.

2. Motor System: Enables movement and object manipulation.

3. Control System: Analyzes sensory info for response commands.

Spatial Coding Characteristics:

• The Simon Effect and spatial compatibility effects differ.

• Cognitive vs. anatomical pathways analysis.

Key Findings:

• Spatial compatibility enhances response efficiency, defined as the degree of natural correspondence between stimuli and responses (Sanders & McCormick, 1993).

Reaction Time Parameters:

• Differentiation of ipsilateral and contralateral mappings.

• Empirical findings reveal that spatial compatibility is mainly influenced by response goal position rather than effector location.
