ABA Fundamentals

Transformation of avoidance response functions in accordance with same and opposite relational frames.

Dymond et al. (2007) · Journal of the experimental analysis of behavior 2007
★ The Verdict

Avoidance can be learned through language alone, so assess relational networks, not just direct trauma.

✓ Read this if BCBAs treating anxiety, phobia, or rigid avoidance in any setting.
✗ Skip if Clinicians working only on skill-building with no avoidance issues.

01Research in Context

01

What this study did

Dymond et al. (2007) taught adults to pick Same or Opposite relations between shapes.

Next, one shape was paired with mild shock. Participants could press a key to avoid the shock.

The team then tested new shapes that were only linked through the trained relations. No shocks were given to these new shapes.

02

What they found

People who learned Same/Opposite relations avoided the new shapes too, even though they were never shocked.

Control participants, who got no relational training, did not avoid the new shapes.

Avoidance can emerge from language relations alone, without direct bad experiences.

03

How this fits with other research

Dymond et al. (2018) review shows this lab result matches real-life anxiety. Clients may fear places or people simply because they are related to past trauma through words, not direct harm.

Paliliunas et al. (2022) took the idea further. They taught kids with autism hierarchical relations in a game of I Spy. Like Simon’s adults, the children showed new responses without extra training. The 2022 study extends relational training to a clinical population and to hierarchical frames.

Older animal studies such as Zeiler (1968) and Hineline et al. (1969) showed avoidance in rats and pigeons, but only through direct shock. Simon’s work reveals a purely human pathway: avoidance born from language, not pain.

Why it matters

If your client avoids school, apps, or people they have never met, ask what words link these stimuli to past aversive events. You can test and break those links with Same/Opposite or hierarchical relational training. Start by mapping the client’s equivalence network, then retrain key relations to reduce derived avoidance.

03Original abstract

Research on the emergence of human avoidance behavior in the absence of direct contact with an aversive event is somewhat limited. Consistent with work on derived relational responding, the present study sought to investigate the transformation of avoidance response functions in accordance with the relational frames of Same and Opposite. Participants were first exposed to nonarbitrary and arbitrary relational training and testing in order to establish Same and Opposite relations among arbitrary stimuli. The training tasks were; Same-A1-B1, Same-A1-C1, Opposite-A1-B2, Opposite-A1-C2. Next, all possible combinatorially entailed (i.e., B-C and C-B) relations were tested. During the avoidance-conditioning phase, one stimulus (B1) from the relational network signaled a simple avoidance response that cancelled a scheduled presentation of an aversive image and sound. All but one of the participants who met the criteria for conditioned avoidance also demonstrated derived avoidance by emitting the avoidance response in the presence of C1 and the nonavoidance response in the presence of C2. Control participants who were not exposed to relational training and testing did not show derived avoidance. Implications of the findings for understanding clinically significant avoidance behavior are discussed.
