Value-modulated attentional capture depends on awareness.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Attention Research

Background:

• Value-modulated attentional capture (VMAC) is thought to be an automatic process where stimuli associated with rewards gain attentional priority.
• The role of awareness in learning VMAC has been unclear, with previous research suggesting it might be implicit.

Purpose of the Study:

• To investigate the role of awareness of stimulus-reward contingencies in the learning of VMAC.
• To determine if explicit instructions about contingencies are necessary for VMAC to emerge.

Main Methods:

• A replication study and a second experiment with between-group instruction manipulation were conducted.
• Participant awareness of stimulus-reward contingencies was assessed.
• Meta-analytic evidence from existing studies was also analyzed.

Main Results:

• VMAC was absent when participants were not explicitly informed about the stimulus-reward contingency.
• Only the instructed group showed VMAC in the second experiment.
• Participants who became aware of contingencies, even without initial instructions, showed VMAC.
• Meta-analysis confirmed larger VMAC effects in studies with explicit instructions.

Conclusions:

• The learning process underlying VMAC may not be entirely implicit.
• Awareness of stimulus-reward contingencies appears crucial for the development of VMAC.
• Explicit instructions significantly enhance VMAC learning.
