House brokers typically intuit that any type of warmth cause people to buy houses more frequently. Is this empirical reality? The authors investigated this through people's attachment towards advertised houses. A wealth of research has now linked thermoregulation to relationships (cf. IJzerman et al., 2015), and here the authors purport that this extends to people's relationships with house as a more novel solution to an ancient problem: Shielding from the cold. The present package tests a preregistered idea that colder temperatures increase people's need to affiliate and, in turn, increase people's estimations of how homely a house is (measured through communality). The hypotheses of the first two studies were partly right:The authors only found that actual lower temperatures (not motivation and through a cup and outside temperature) induced people to find a house more communal, predicted by their need to affiliate. Importantly, this even predicts whether people find the house more attractive, and increases their willingness to pay for the house (Studies 1 and Study 2). The third study did not pan out as predicted, but still affected people's need to affiliate. The authors reason that this was caused by a methodological shortcoming (namely not directly being affected by temperature). The present work provides novel insights into how a house becomes a home.Keywords: grounded cognition, social thermoregulation, need for affiliation, home, communality, attachment
Homely Thermoregulation: How Physical Coldness Makes an Advertised House a HomeThroughout history, humans have been searching and creating spatial demarcationsfor example alcoves, grottos, huts, and eventually houses -keeping its members safe not only from predation, but also warm under temperatures endangering survival. Because of this vital role in survival, people have formed models of houses with functions beyond survival, as houses can fulfill an belonging need by making it a home (e.g., Dovey, 1985;Fullilove, 1996), or, as attachment theory would have it, a "safe haven" (Manzo, 2003;Moore, 2000).Here, we propose that the cognitive mechanisms framing those spatial demarcations as "home" are derived from the same physiological mechanisms that originally helped us to be shielded from the cold through other people.Amongst early humans and other mammals, conspecifics helped in keeping us warm in order to decrease the metaboblic costs of a cold environment (cf. IJzerman and colleagues, 2015). But as effective as relationships may be in relating to others, a house may well have (partly) replaced those socially borne functions, in the same way as lower temperatures sparks attachment to other people and can be fulfilled through renting romance movies (Hong & Sun, 2012) or feeling nostalgic (Zhou et al., 2012). We will explicate and empirically validate how houses offer a socially supportive function -fulfilling the "need to affiliate" through "feeling at home" -all of it fulfilling thermoregulatory needs. Finally, we think that the link between tem...
