S-R Compatibility

Question 1

What does S-R Compatibility stand for?

Answer 1

• Stimulus-Response Compatibility

Question 2

Explain a simplified understanding of S-R Compatibility

Answer 2

• Reaction time is faster and more accurate when spatial relations are congruent
• Stimulus and response location compatible

Question 3

What is the evidence for S-R compatibility?

Answer 3

2 Choice RT task
- Faster ipsilateral than contralateral

Question 4

What is more favoured explaination of S-R compatibility?

Answer 4

• Pre-programmed cognitive response

Question 5

Why is it important to understand S-R compatibility?

Answer 5

• Key in everyday tasks (from lab to use of machinery)
• Insight to cognitiv e processes between perception and action

Question 6

What are some key points for S-R compatibility?

Answer 6

• Stimulus and Response coded in terms of spatial location
• When Stimulus and Response spatial locations match it is the most compatible
• SRP effects attributed to greate efficiency in translating input-output
• Can be explicit or implicit

Question 7

Define and Describe the characterisitcs of spatial coding

Answer 7

• Stimulus and response are represented in terms of spatial locations
• Can be location or symbol
• When stimulus/response match, response are faster and more accurate
• SRC effects attributed to more efficient cognitive translation between stimulus-response codes

Question 8

What is the difference between cognitive coding and anatomical pathway mechanisms?

Answer 8

Cognitive Coding
- Translation of stimulus to response
Anatomical Pathway
- Involves hemispher transferring information

Question 9

How can frame of reference impact compatiblity effects?

Answer 9

• based on subject perception and vertical axis of vision

Question 10

Define Orthogonal Spatial Compatibility and describe the purpose of examining orthogonal spatial relations

Answer 10

• when stimulus and response dimensions dont correspond, more salient elements of each will stand out and be mapped together

Question 11

Describe and Explain teh Basis of the Salient feautres Coding Principle

Answer 11

• Stimulus and response sets can be coded in terms of the salient features of each dimension
• Translation is faster when salient features of a stimulus and response are mapped together

Question 12

Define and Describe the Simon Effect

Answer 12

• Respond to stimulus feature
• Location of Stimulus Irrelevant
• Stimulus features are mapped to spatial responses

Question 13

Distinguish betwen the spatial compatibility and simon effects

Answer 13

• One which location of stimulus is relevant and one is not
• Simon effect reduces SRC effect over time
