Summary
Overthinking, specifically verbalizing golf-putting actions, impairs skilled athletes' motor skill memory. This verbal overshadowing effect did not impact lower-skilled golfers, suggesting memory interference.
Area of Science:
- Cognitive Psychology
- Motor Learning
- Neuroscience
Background:
- Athletes report overthinking hinders motor skill performance.
- Verbal overshadowing describes how articulating perceptual experiences can impair memory recall.
Purpose of the Study:
- To investigate if verbalizing motor actions causes performance deficits in athletes.
- To explore the link between overthinking, verbal overshadowing, and motor skill memory.
Main Methods:
- Participants learned a novel golf-putting task.
- Golfers of varying skill levels either described their putting actions or performed a control verbal task.
- Performance was re-assessed after the verbal task.
Main Results:
- Describing putting actions significantly impaired higher-skilled golfers' performance.
- Lower-skilled golfers showed no performance decrement after verbalization.
- The effect extended beyond simple dual-task interference.
Conclusions:
- Verbalizing motor skills can negatively impact long-term memory for those skills.
- This suggests a competition between procedural and declarative memory systems.
- Findings support the idea that overthinking can disrupt motor skill execution through memory mechanisms.

Hierarchy of Motor Control
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.
Self-Presentation: Self-Monitoring and Self-Handicapping
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...
Steps in the Modeling Process
Albert Bandura's theory of observational learning identifies four critical processes: attention, retention, motor reproduction, and reinforcement or motivation.
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...

Self-Discrepancy Theory
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
Social Facilitation
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.
Hindsight Biases
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?
