Learned helplessness, depression, and anxiety.

Area of Science:

• Psychology
• Clinical Psychology
• Cognitive Psychology

Background:

• The learned helplessness model of depression posits that individuals with depression perceive reinforcement as independent of their responses, particularly in skill-based tasks.
• Understanding these perceptual distortions is crucial for developing effective depression treatments.

Purpose of the Study:

• To investigate whether depressed individuals perceive outcomes in skill tasks as response-independent, aligning with the learned helplessness model.
• To examine expectancy changes in skill versus chance tasks among depressed-anxious, nondepressed-anxious, and nondepressed-nonanxious college students.

Main Methods:

• Participants estimated their success probabilities in skill and chance tasks.
• Group comparisons were made between depressed-anxious, nondepressed-anxious, and nondepressed-nonanxious students.
• Performance on a discrimination learning problem and latency to terminate aversive noise were assessed.

Main Results:

• Depressed-anxious subjects showed less expectancy change in skill tasks compared to nondepressed-anxious subjects.
• Expectancy changes in chance tasks were similar between depressed-anxious and nondepressed-anxious groups.
• No significant differences were found between nondepressed-anxious and nondepressed-nonanxious groups in either task type.

Conclusions:

• Depressed individuals may perceptually distort outcomes of skilled responses as being uncontrollable or response-independent.
• These deficits in learning response consequences may be specific to depression and reflect learned helplessness.
• Findings support the learned helplessness model's prediction of altered response-outcome expectancies in depression.
