The relationship between self, value-based reward, and emotion prioritisation effects.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Behavioral Economics

Background:

• Humans exhibit systematic biases in perception, memory, attention, and decision-making.
• These biases prioritize information related to self, reward, and positive emotion.
• The precise relationship between these prioritization effects is not well understood.

Purpose of the Study:

• To investigate the associations between self, reward, and positive emotion prioritization effects.
• To explore individual differences in these cognitive prioritization mechanisms.
• To determine if common properties underlie these distinct biases.

Main Methods:

• Three experiments utilized a common associative matching procedure.
• Cluster and shift function analyses were employed to assess prioritization effects.
• Individual differences in response times were analyzed in relation to biases.

Main Results:

• Self-prioritization effects appeared independent of reward or emotion biases.
• Two distinct patterns emerged: faster responders showed linear reward-emotion associations, while slower responders showed non-associated large reward biases.
• Slower responders exhibited reward processing dominance at later stages, unlike faster responders.

Conclusions:

• The self-prioritization effect likely originates independently from value-based processing.
• Cognitive mechanisms for reward and positive emotion processing share commonalities but are influenced by individual differences.
• Findings contribute to understanding the interplay of fundamental behavioral drivers.
