Question

sleepiness among participants. the weather also hurt their ability to think critically: the hotter it got, the less likely they were to question what they were told. the shift toward mindlessness may be rooted in our emotions. one common finding is a link between relative sunshine and happiness: although people who live in sunnier places, like southern california, are no happier than those who live in the harsher conditions of the midwest, day - to - day variations in sunshine make a difference. people get happier as days get longer and warmer in the approach to the summer solstice, and less happy as days get colder and shorter. they also report higher life satisfaction on relatively pleasant days. the happiest season, then, is summer. a good mood, generally speaking, has in turn been linked to the same type of heuristic, relatively mindless thinking that clore observed in his pleasant - weather participants. on the flip side, a bad mood tends to stimulate more rigorous analytical thought. weather - related mood effects can thus play out in our real - life decisions - even weighty ones. in one recent project, the psychologist uri simonsohn found that students were more likely to enroll in a university that was famous for its academic rigor if they visited on days that were cloudy. when the weather turned sour, he concluded, the value they placed on academics increased. according to clores study, warmer weather... a decreases happiness but improves critical thinking. b increases happiness but discourages critical thinking. c improves mood but has no impact on critical thinking. d improves productivity and distracts from unnecessary worries.
