How Fears Are Learned and Unlearned


Chapter 5: Learning

Learning Outcomes

  • Analyze the psychological mechanisms underlying maladaptive avoidance behavior in anxiety disorders
  • Apply psychological theories to real-life scenarios involving anxiety and avoidance
  • Evaluate the effectiveness of different therapeutic approaches based on the underlying cause of avoidance

Key Terms

classical conditioning
learning in which the stimulus or experience occurs before the behavior and then gets paired or associated with the behavior
conditioned stimulus (CS)
stimulus that elicits a response due to its being paired with an unconditioned stimulus
extinction
decrease in the conditioned response when the unconditioned stimulus is no longer paired with the conditioned stimulus
spontaneous recovery
return of a previously extinguished conditioned response
stimulus generalization
demonstrating the conditioned response to stimuli that are similar to the conditioned stimulus

Exercise Anxiety

Esme is a 19-year-old college freshman who used to love running. But after a panic attack during a treadmill workout last year, she stopped exercising altogether. She now avoids gyms, running paths, and even walking briskly across campus. This pattern reflects stimulus generalization, where fear spreads to situations that resemble the original panic trigger.

Her avoidance has started affecting her social life and academics. She skips classes held in large lecture halls and avoids group projects. Esme's therapist suspects her behavior is more than just fear; it may be maladaptive avoidance, a key feature in anxiety disorders.

1. On Your Own

Which of the following best describes Esme's behavior? Select the best answer.

Why Does Esme Avoid?

Esme's therapist explains that her avoidance may stem from one or more neurobehavioral processes:

  • heightened threat appraisal because Esme overestimates the danger of her racing heart
  • habitual avoidance because she's developed a pattern of avoiding physical activity
  • trait avoidance tendency because Esme may have a natural inclination to avoid discomfort

Understanding which process is dominant can help tailor her treatment. For example, exposure therapy may help if threat appraisal is the issue, while habit reversal might be better for habitual avoidance. The following is a summary of the processes, their descriptions, Esme's example, and the best treatment approach, according to Esme's therapist.

Table 1Neurological Processes and Their Treatments as Related to Esme's Situation
Process Description Esme's example Best treatment approach
threat appraisal overestimating danger avoids running due to fear of panic exposure therapy, cognitive restructuring
habitual avoidance automatic, cue-based avoidance skips class without evaluating fear habit reversal, behavioral activation
trait avoidance tendency dispositional tendency to avoid avoids group work despite low fear acceptance and commitment therapy (ACT), values-based interventions

Treatment and Research Implications

Esme begins exposure therapy, gradually reintroducing physical activity in safe, controlled ways. Her therapist also tracks her fear responses and avoidance patterns to identify which neurobehavioral process is most active.

Understanding these processes helps clinicians tailor treatments. For instance:

  • Exposure therapy is most effective when avoidance is driven by threat appraisal.
  • Habit reversal training may be better for habitual avoidance.
  • ACT can help individuals with high trait avoidance focus on values-based actions rather than fear-based decisions.

In research, maladaptive avoidance is studied using paradigms like:

  • extinction-resistant avoidance: when avoidance persists even after the threat is gone
  • avoidance generalization: when fear spreads to similar but safe situations
  • competing reward paradigms: when avoidance leads to missed opportunities for positive outcomes

These models help psychologists understand how avoidance develops, persists, and can be treated. Esme's case, though personal, reflects a broader psychological truth: Avoiding fear may feel safe, but facing it is often the path to healing.

3. On Your Own

Which of the following are potential consequences of maladaptive avoidance? Select the three that apply.

Correct! Reduced social interaction, academic impairment, and increased anxiety are all potential consequences of maladaptive avoidance.

Broader Psychological Context

Esme's story is a powerful illustration of how maladaptive avoidance can become a self-reinforcing cycle in anxiety disorders. In psychology, avoidance is considered a negative reinforcement strategy. It removes an aversive stimulus, such as fear or discomfort, which makes the behavior more likely to occur again. While this may offer short-term relief, it often leads to long-term impairment.

Avoidance also interferes with learning that feared situations are often safe or manageable. This process is shaped by classical conditioning, where a neutral experience like running becomes associated with panic through repeated pairing. Over time, running itself becomes a conditioned stimulus (CS): a trigger that elicits fear because of its connection to the panic episode.

This cycle is central to many anxiety-related disorders, including:

  • social anxiety disorder: avoiding social situations due to fear of embarrassment
  • posttraumatic stress disorder (PTSD): avoiding trauma reminders to escape distress
  • obsessive-compulsive disorder (OCD): avoiding triggers that provoke obsessive thoughts

Avoidance and Anxiety Disorders

Avoidance is not just a symptom. It is a central mechanism that drives and maintains anxiety disorders, including PTSD and OCD. It can be deceptively comforting, offering short-term relief from distress, but ultimately it reinforces fear and limits personal growth.

Esme's progress is slow but steady. She is now walking to class and has even joined a study group. Her therapist continues to monitor her responses and adjusts treatment as needed. This is especially important because spontaneous recovery can occur. That is when old fear responses briefly return even after progress has been made.

Reflect & Respond

Answer the following questions to reflect on key ideas from the case study. Remember to print your work before leaving this page!

  1. How did Esme's avoidance behavior initially help her cope with anxiety, and how did it become maladaptive over time? Consider the short-term relief versus long-term consequences.
  2. Which neurobehavioral process, such as threat appraisal, habitual avoidance, or trait avoidance tendency, do you think played the biggest role in Esme's behavior? Why?
  3. How might Esme's treatment plan differ if her avoidance was primarily driven by habit rather than fear? Think about how different therapies target different mechanisms.
  4. Can you think of a time when you or someone you know avoided something out of fear or discomfort? Was the avoidance adaptive or maladaptive?
  5. Why is it important for psychologists to understand the underlying cause of avoidance behavior rather than just treating the symptoms?
