Disgust provides an advantage in episodic memory. Research suggests this advantage applies not only to inherently disgusting stimuli but also to neutral stimuli associated with disgust. However, it remains unclear whether neutral stimuli sharing categorical features with disgust-associated stimuli (but lacking direct association) also benefit from this advantage. To investigate this, a categorical conditioning paradigm was employed. Objects from two categories (vehicles and furniture) were paired with either disgust-related images (US+) or neutral images (US-). In the first stage, participants viewed 30 objects from each category individually. In the second stage, category conditioning involved a separate set of 30 objects from each category. Episodic memory was tested immediately after learning or after a 24-hour or 1-week delay. It was hypothesized that objects from the disgust-associated category would be remembered better, even without direct association, due to acquired disgust value. Emotional ratings showed that participants rated CS+ stimuli as more disgusting and negative than CS- stimuli in the second stage, with no difference in the first stage. ROC analysis revealed superior recognition accuracy and liberal bias for categorical stimuli presented in the second stage compared to the first. CS+ stimuli were remembered more accurately and with greater liberal bias than CS- stimuli, regardless of stage or delay. Disgust-associated categories retrospectively enhance episodic memory, underscoring the nuanced influence of disgust on memory processes.
