Anxiety and Ironic Errors of Performance: Task Instruction Matters.

Area of Science:

• Psychology
• Cognitive Psychology
• Motor Control

Background:

• Wegner's theory of ironic processes suggests that attempting to suppress unwanted thoughts can paradoxically increase their occurrence.
• This theory has implications for mental control under pressure, particularly in performance contexts.

Purpose of the Study:

• To examine ironic processes of mental control in reactive motor performance under pressure.
• To investigate whether task instructions moderate the incidence of ironic errors in reactive motor tasks.

Main Methods:

• Five experiments were conducted using a reactive motor task involving reacting to colored balls under low- and high-anxiety conditions.
• Measures included anxiety, heart rate, heart-rate variability, and muscle activity to confirm anxiety manipulation effectiveness.

Main Results:

• Experiments 1, 2, and 4 demonstrated that anxiety significantly increased the number of ironic errors in the reactive motor task.
• Experiments 3 and 5 provided the first evidence that instructional interventions can mitigate anxiety-induced ironic performance errors.

Conclusions:

• Anxiety exacerbates ironic errors in reactive motor performance.
• Instructional strategies can effectively reduce performance decrements caused by anxiety-induced ironic processes.
