A derived transfer of functions and the implicit association test

Area of Science:

• Behavioral Psychology
• Cognitive Science
• Linguistics

Background:

• Equivalence classes are formed through training, linking stimuli in a systematic way.
• Evaluative functions (positive/negative) can be associated with stimuli.
• The Implicit Association Test (IAT) measures reaction times to assess associations.

Purpose of the Study:

• To investigate if the Implicit Association Test (IAT) effect is influenced by the formation of equivalence classes.
• To examine the transfer of evaluative functions to derived stimulus relations.
• To explore the role of derived relations in modeling semantic categories.

Main Methods:

• Participants underwent training to establish four 4-member equivalence classes.
• Stimuli within equivalence classes were compounded with positive or negative evaluative functions.
• The Implicit Association Test (IAT) was used to measure the transfer of evaluative functions.

Main Results:

• Participants who passed an equivalence test showed a typical IAT effect (faster responses on consistent blocks).
• This IAT effect was not observed in participants who did not pass the equivalence test.
• Results indicate a link between successful equivalence class formation and the IAT effect.

Conclusions:

• The IAT effect may arise from formally untested derived relations within equivalence classes.
• Derived relations could serve as a valid behavioral model for semantic categories in natural language.
• This study supports the role of derived stimulus relations in cognitive processes.
