Brown rats exhibit cognitive bias, where by data processing is biased by whether or not they are in a beneficial or damaging affective condition.[78] By way of example, laboratory rats educated to reply to a particular tone by pressing a lever to get a reward, also to press another lever in response to another tone in order to stay away from getting An electrical shock, are more likely to reply to an intermediate tone by deciding on the reward lever if they've just been tickled (something they take pleasure in), indicating "a url concerning the instantly calculated constructive affective point out and final decision generating beneath uncertainty within an animal product."[79]
