Effect of episodic specificity induction on divergent thinking: A meta-analytic study

Area of Science:

• Cognitive Psychology
• Creativity Research

Background:

• Episodic Specificity Induction (ESI) involves training in episodic recall.
• The constructive episodic simulation hypothesis suggests ESI enhances divergent thinking by aiding memory access for idea generation.

Purpose of the Study:

• To meta-analyze the impact of ESI on divergent thinking performance.
• To investigate potential publication bias in ESI research.

Main Methods:

• A meta-analysis was conducted on 21 samples from 16 experiments across ten studies.
• Divergent thinking performance metrics including fluency, flexibility, originality, and elaboration were assessed.

Main Results:

• A small, potentially nullified effect of ESI was found on fluency and flexibility after correcting for publication bias.
• No significant effects of ESI were observed on qualitative aspects of divergent thinking, such as originality and elaboration.
• Publication bias assessments yielded mixed results, suggesting underrepresentation of null findings.

Conclusions:

• The positive effects of ESI on divergent thinking appear minimal and potentially inflated by publication bias.
• Further research is required to identify specific ESI components that might genuinely enhance creative thinking.
