Pewni badacze chcieli sprawdzić czy ocena produktu jest taka sama w zimnym i ciepłym pomieszczeniu. Badani oceniali produkt na skali 1-7 (gdzie wysokie wyniki oznaczają wysoką atrakcyjność). Połowa badanych oceniała produkt (nieznany proszek do prania) w pomieszczeniu, gdzie utrzymywano temperaturę 10 stC, a druga połowa w pomieszczeiu, gdzie było 25 stC. Badacze zakładali, że osoby, które znajdują się w ciepłym pomieszczeniu będą lepiej oceniały produkt, niż osoby, które dokonują ewaluacji w pomieszczeniu zimnym.
