Navigating decision space: Causal structure improves performance in a branching choice task.

Area of Science:

• Cognitive Psychology
• Decision Science
• Human-Computer Interaction

Background:

• Prior research indicates causal structure impacts episodic memory recall.
• The current study extends this to decision-making in goal-directed tasks.

Purpose of the Study:

• To investigate if causal structure benefits performance in decision-making tasks.
• To determine the role of episodic memory and specific cues in this benefit.

Main Methods:

• Participants navigated 'coherent' (causally linked) and 'fragmented' (statistically linked) decision trees.
• Experiments manipulated the presence of an initial exploration phase, process images, and text labels.

Main Results:

• Participants performed significantly better (fewer attempts) in coherent trees.
• This advantage was largely independent of episodic memory (exploration phase).
• Removing process images or text labels individually did not eliminate the benefit; only removing both did.

Conclusions:

• Causal coherence enhances goal-directed decision-making.
• Cues like process images and text labels facilitate decision-making without extensive learning.
• The benefit of causal structure is robust and not solely dependent on episodic memory.
