Brown rats show cognitive bias, wherever information and facts processing is biased by whether they are within a optimistic or adverse affective state.[78] For instance, laboratory rats educated to reply to a specific tone by pressing a lever to get a reward, and to press A different lever in reaction to a different tone so as to steer clear of acquiring An electrical shock, usually tend to respond to an intermediate tone by picking out the reward lever if they have just been tickled (anything they enjoy), indicating "a url concerning the straight measured favourable affective condition and selection earning underneath uncertainty within an animal product."[79]
