Functional Fixedness in Creative Thinking Tasks Depends on Stimulus Modality.

Area of Science:

• Cognitive Psychology
• Semantic Memory Research

Background:

• Pictorial examples in creative tasks can lead to fixation and suboptimal outcomes.
• Semantic memory research offers insights into the cognitive mechanisms behind this effect.

Purpose of the Study:

• To investigate how pictures versus words influence semantic knowledge access for object concepts.
• To determine if this influence differs between close-ended and open-ended creative tasks.

Main Methods:

• Participants generated uses (common, secondary, ad hoc) for objects presented as names, pictures, or both.
• Stimulus modality effects were measured using reaction times and a novel coding system for response type (top-down vs. bottom-up).

Main Results:

• Both quantitative and qualitative analyses showed task-dependent differences in stimulus modality effects.
• For ad hoc uses (open-ended), pictures led to more top-down-driven responses compared to object names.

Conclusions:

• Visual stimuli can increase fixation on existing knowledge, particularly in open-ended creative contexts.
• Findings contribute to understanding functional fixedness in creative thinking and semantic memory for objects.
