Verbal working memory and planning: learning to compare movement durations of objects

Area of Science:

• Cognitive Psychology
• Neuroscience

Background:

• Duration judgments are influenced by cognitive processes, including working memory.
• Understanding how learning affects these judgments and their relationship with working memory is crucial for cognitive science.

Purpose of the Study:

• To investigate the relationship between duration judgments and verbal/visual working memory.
• To examine the effect of learning logical planning on duration judgments and their association with working memory capacity.

Main Methods:

• Participants (N=30) judged longer durations of car movements on a monitor.
• They then learned to solve Piagetian tasks logically and retook the duration judgment task.
• Verbal and visual working memory capacities were assessed post-learning.

Main Results:

• Performance on Piagetian tasks correlated with verbal and visual working memory capacity.
• This correlation remained significant even after participants learned logical problem-solving strategies.
• The learning intervention did not significantly alter the relationship between working memory and duration judgments.

Conclusions:

• Cognitive strategies learned for logical tasks do not fundamentally change the interplay between working memory and duration perception.
• Working memory capacity appears to be a stable factor influencing duration judgments, irrespective of specific task-learning interventions.
