This is the abstract:
Metaphors such as icy stare depict social exclusion using cold-related concepts; they are not to be taken literally and certainly do not imply reduced temperature. Two experiments, however, revealed that social exclusion literally feels cold. Experiment 1 found that participants who recalled a social-exclusion experience gave lower estimates of room temperature than did participants who recalled an inclusion experience. In Experiment 2, social exclusion was directly induced through an on-line virtual interaction, and participants who were excluded reported greater desire for warm food and drink than did participants who were included. These findings are consistent with the embodied view of cognition and support the notion that social perception involves physical and perceptual content. The psychologicalexperience of coldness not only aids understanding of social interaction, but also is an integral part of the experience of social exclusion.
The paper does pretty much what it says on the box. In experiment 1 a total of 65 subjects (undergraduate students, the rat of social psychology) were told they would perform a series of unrelated tasks. In the first they recalled either an experience where they felt very socialy excluded, or socially included. Then they were asked to estimate the temperature in the room. Subjects who had recalled being excluded gave lower estimates (their mean estimate was about 2.5 degrees Centrigrade lower) than subjects who had recalled being included.
In experiment 2 a total of 52 subjects played the popular cyberball game (in which a virtual ball is passed between the player and two virtual players, with the fraction of passes to the subject being a proxy for levels of inclusion). They were then asked to rate the desirability of 5 different products including a warm drink and a warm food and a cold drink and a cold food. Excluded subjects rated the warm food and drink as more desirable (by about 1 point on a 7 point Likert scale) than controls, while rating the cold food and drink neither better nor worse.
So if you're wondering whether your guests feel welcome or not, ask whether they want tea or a soda...
As so often with social psychology, the interesting result is described in terms of a fairly qualitative theory sketch in terms of 'schemas'. It would be good to know more about this from the perspective of cognitive neuroscience.
