Cognitive control influences stimulus-response (S-R) associations, impacting both stimulus-classification (S-C) and stimulus-action (S-A) mappings. Findings suggest a conflict adaptation mechanism underlies these effects.
Area of Science:
- Cognitive Psychology
- Neuroscience
Background:
- Stimulus-response (S-R) associations are fundamental to behavior.
- These associations comprise distinct stimulus-classification (S-C) and stimulus-action (S-A) components.
Purpose of the Study:
- To investigate the role of cognitive control in modulating S-R associations.
- To determine if S-C and S-A associations are independently influenced by cognitive control.
Main Methods:
- Two item-specific priming experiments were conducted.
- List-level proportion manipulations of S-C and S-A mapping repetitions/switches were employed.
- The impact on S-C and S-A association strength was assessed.
Main Results:
- Switching S-C or S-A mappings between prime and probe trials led to slower responses and increased errors.
- S-C and S-A switch effects were modulated by the list-level proportion of switches.
- Results supported a conflict adaptation mechanism over contingency or temporal learning.
Conclusions:
- Cognitive control mechanisms adaptively modulate S-R components.
- This adaptation influences both the encoding and retrieval stages of S-R associations.
- Findings offer insights into the cognitive control of S-R associations within item-specific priming.

pre-mRNA Processing
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...
Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
