Abstract: Cognitive judgement bias (CJB) refers to the interpretation of ambiguous stimuli in a negative (pessimistic) or positive (optimistic) way. Negative CJB is observed in depression and anxiety disorders. To investigate this behaviour in preclinical animal models, animals learn to touch one stimulus to receive milkshake reward and withhold responding from a different stimulus to avoid noise and a flashing light. During probe testing, untrained ambiguous stimuli (mixtures of the two trained stimuli) are presented and the animal’s responding to these stimuli reflects their optimistic-like or pessimistic-like bias which serves as an indirect indicator of their affective state.
