Since laboratory mice (residence mice) and rats (brown rats) are greatly used as scientific models to further our idea of biology, an awesome deal has arrive at be identified with regards to their cognitive capacities. Brown rats here show cognitive bias, where by information and facts processing is biased by whether they are within a positive or detrimental affective condition.[78] As an example, laboratory rats properly trained to reply to a certain tone by pressing a lever to receive a reward, and to press A different lever in reaction to a unique tone in order to keep away from getting an electric shock, are more likely to respond to an intermediate tone by choosing the reward lever if they have got just been tickled (a thing they appreciate), indicating "a hyperlink between the instantly measured favourable affective state and decision earning below uncertainty in an animal model."[79]
