Stimulus devaluation induced by action stopping is greater for explicit value representations.

Area of Science:

• Cognitive Neuroscience
• Behavioral Economics

Background:

• Action stopping near reward cues has been shown to reduce subjective stimulus value.
• Exploratory analyses suggested explicit knowledge may moderate this devaluation effect.

Purpose of the Study:

• To systematically investigate the influence of explicit knowledge on stopping-induced stimulus devaluation.
• To replicate and extend previous findings on action stopping and value reduction.

Main Methods:

• Replication of a prior study involving implicit learning of stimulus-value associations.
• A treatment phase where some stimuli were paired with action stopping.
• An auction phase to assess subjective stimulus value and correlation with explicit knowledge.

Main Results:

• The study successfully replicated the core finding that action stopping reduces stimulus value.
• A significant interaction revealed that the devaluation effect was larger for participants with greater explicit knowledge of stimulus values.

Conclusions:

• The stopping-induced devaluation effect is robust and modulated by explicit knowledge.
• Findings suggest potential applications for behavioral therapies targeting the devaluation of real-world stimuli.
• Open-source code is provided to facilitate further research into stopping-induced devaluation mechanisms.
