Stroop-like effects of derived stimulus-stimulus relations.

Area of Science:

• Cognitive Psychology
• Learning and Memory
• Human Behavior

Background:

• Automaticity in behavior is typically established through consistent reinforcement of specific actions.
• Reinforcement learning can also lead to the derivation of novel associations not directly reinforced.

Purpose of the Study:

• To investigate whether derived relations, established without direct reinforcement, can induce automatic effects.
• To examine the conditions under which derived associations influence cognitive tasks, specifically the Stroop task.

Main Methods:

• Participants were trained to derive associations between nonsense words and color words.
• These derived associations were then tested using a Stroop task where nonsense words served as distractors.
• Attention allocation to distractor words was manipulated during the Stroop task.

Main Results:

• Derived color-word associates induced significant Stroop effects, indicating automatic interference.
• The Stroop effect was contingent on sufficient attention being allocated to the distractor words.
• The observed effect was driven by response conflict, suggesting a lexical-level association.

Conclusions:

• Derived associations can indeed lead to automatic processing effects under specific training and attentional conditions.
• These effects appear to operate at the lexical level, linking the derived word to its associated color.
• Derived associates did not achieve direct access to semantic color representations in this study.
