Simply because laboratory mice (home mice) and rats (brown rats) are greatly utilized as scientific versions to more our idea of biology, an excellent deal has come to be known regarding their cognitive capacities. Brown rats exhibit cognitive bias, wherever data processing is biased by whether they are inside of a constructive or unfavorable affective point out.[seventy eight] For instance, laboratory rats skilled to respond to a particular tone by pressing a lever to get a reward, also to push One more lever in response to a distinct tone to be able to avoid getting An electrical shock, usually tend to reply to an intermediate tone by choosing the reward lever if they've just been tickled (some thing they take pleasure in), indicating "a hyperlink in between the straight measured favourable affective state and conclusion generating under uncertainty within an animal design."[79]
