What I like is what I remember: Memory modulation and preferential choice.

Area of Science:

• Cognitive Psychology
• Decision Science
• Computational Neuroscience

Background:

• Memory is integral to decision-making, yet the interplay between memory processes and choice behavior remains poorly understood.
• Established memory regularities, such as primacy, recency, and semantic clustering, are well-documented in standard recall tasks.
• It is unclear if these memory patterns persist when decisions are based on memory content.

Purpose of the Study:

• To investigate how established memory regularities manifest in preferential choice tasks.
• To compare memory processes in standard list recall versus memory-based decision-making.
• To determine the influence of decision-relevant features on memory retrieval during choice.

Main Methods:

• Development of a novel experimental paradigm to contrast memory recall and preferential choice.
• Application of computational memory models to analyze data from two preregistered experiments.
• Quantitative assessment of memory regularities (primacy, recency, semantic/temporal clustering) in both task types.

Main Results:

• Primacy, recency, and semantic clustering effects were observed in preferential choice, similar to standard recall.
• Temporal clustering was significantly weaker in preferential choice compared to standard list recall.
• Item desirability emerged as a critical factor influencing memory retrieval during choice tasks.

Conclusions:

• Memory processes are distinct in preferential choice tasks compared to standard memory recall.
• Choice modulates memory retrieval by differentially emphasizing decision-relevant attributes, such as item desirability.
• Understanding how choice influences memory provides insights into cognitive decision-making mechanisms.
