Since laboratory mice (residence mice) and rats (brown rats) are widely employed as scientific products to more our idea of biology, an excellent offer has arrive at be regarded regarding their cognitive capacities. Brown rats exhibit cognitive bias, exactly where information and facts processing is biased by whether they are inside a positive or adverse affective point out.[78] For example, laboratory rats qualified to answer a selected tone by pressing a lever to get a reward, and also to press A further lever in reaction to another tone so as to avoid obtaining an electric shock, usually tend to reply to an intermediate tone by deciding on the reward lever if they've got just been tickled (a little something here they get pleasure from), indicating "a backlink concerning the directly measured optimistic affective point out and decision making less than uncertainty in an animal model."[79]
