We propose that people who are cold (vs. warm) have a higher (vs. lower) need for affiliation. In turn, we think that people who are cold (vs. warm) will rate houses as more communal (thus as a reflection of their motivation for warmth). In Study 1, we wanted to investigate whether taking away the motivation to get warm, when being in a cold situation, influences this warmth-evaluation link. Furthermore, we wanted to explore the effect on other related factors: Perceived quality and attractiveness. The house that was used for this investigation is a house that is for sale and will be presented as a real estate brochure. The experiment consists of three conditions. In the first condition (the ''staying outside'' condition) participants were approached outside, where it was cold. We expected participants in this condition to evaluate the house more positive on communality than an inside condition (and a condition in which we took desire for warmth away). We also explored whether similar effect occur on attractiveness and perceived quality. In the second condition (the ''going inside'' condition) participants were approached outside, where it was thus cold. In this condition however, we told participants that we start the experiment outside, but finish it inside. This way, we thought we could take away the motivation toward affiliation and warmth. In this condition we expected participants to evaluate the house as less positive on communality than the outside condition (but comparable to an inside condition). We again explore effects on attractiveness and perceived quality. In the final condition, participants were thus approached inside, where it was warmer. We expected all the effects to be mediated by a Need for Affiliation (which is thus induced by feeling cold). ## Summary of the hypotheses Study 1 ## - Hypothesis 1: Participants in the “staying outside” condition would evaluate a house more positive communality than participants in the “going inside” and control condition (a comparable effect may have emerged on perceived quality and attractiveness). We did not expect the effect to differ for the going inside and control condition. - Hypothesis 2: Participants in the “staying outside” condition would have a higher need for affiliation than participants in the “going inside” and control condition. Again, we did not expect differences between the going inside and control condition. - Hypothesis 3: Need for affiliation mediates the relationship between physical temperature and evaluation of a house such that participants in the “staying outside” condition (vs. going inside and inside conditions) would have a higher need for affiliation and this will lead to a more positive evaluation of communality of a house (a comparable effect may have emerged on perceived quality and attractiveness).
