Trust lies at the heart of person perception and interpersonal decision making. In two studies, we investigated physical temperature as one factor that can influence human trust behavior, and the insula as a possible neural substrate. Participants briefly touched either a cold or warm pack, and then played an economic trust game. Those primed with cold invested less with an anonymous partner, revealing lesser interpersonal trust, as compared to those who touched a warm pack. In Study 2, we…

Damage to the insula is associated with abnormal interpersonal trust
Electrodes as social glue: measuring heart rate promotes giving in the trust game.
The ‘warm’ side of coldness: Cold promotes interpersonal warmth in negative contexts
The relationship between the experience of physical temperature and interpersonal outcomes is context dependent and participants touching cold objects were more likely to complain and those touching warm objects were less likely to complaining compared with the control group.
1 Chapter 9 . Trust and Emotions
In the current chapter, we review research investigating the influences of affective states on trust. To delineate the behavioral and neural effects of emotions on trust decisions we consider
The Caudate Signals Bad Reputation during Trust Decisions
The findings suggest that the caudate is involved in signaling and integrating reputations gained through experience into trust decisions, demonstrating a neural basis for this key social process.
The Role of Temperature in Moral Decision-Making: Limited Reproducibility
It is proposed that, at least in the range of temperatures from 21 to 27°C, the cool temperature effect in moral decision-making is not a robust phenomenon.
The Effect of Haptic and Ambient Temperature Experience on Prosocial Behavior
Temperature is an ever-present feature of the environment, but we are still unsure how changes in temperature experience affect human behavior. On the one hand, some studies have shown that higher
The Effects of Temperature Priming on Cooperation in the Iterated Prisoner's Dilemma

Temperature priming on 30 pairs of British university students with hot and cold objects on frequency of cooperation in a game of iterated Prisoner's Dilemma found participants were found to cooperate significantly more frequently when primed with hot objects than with cold objects, supporting the assertion that physical warmth sensation positively affects interpersonal trust evaluation.


Experiencing Physical Warmth Promotes Interpersonal Warmth
“Warmth” is the most powerful personality trait in social judgment, and it is hypothesized that experiences of physical warmth would increase feelings of interpersonal warmth, without the person's awareness of this influence.
The Thermometer of Social Relations
These studies corroborate recent findings in the field of grounded cognition revealing that concrete experiences ground abstract concepts with which they are coexperienced and show a systemic interdependence among language, perception, and social proximity.
Perceptions of moral character modulate the neural systems of reward during the trust game
As expected from previous studies, activation of the caudate nucleus differentiated between positive and negative feedback, but only for the 'neutral' partner, suggesting that prior social and moral perceptions can diminish reliance on feedback mechanisms in the neural circuitry of trial-and-error reward learning.
The Sunny Side of Fairness
Analysis of self-reported happiness and neural responses to fair and unfair offers provides evidence that fairness is hedonically valued and that tolerating unfair treatment for material gain involves a pattern of activation resembling suppression of negative affect.
Evaluating face trustworthiness: a model based approach.
This model generated novel faces with an increased range of trustworthiness and used these faces as stimuli in a functional Magnetic Resonance Imaging study, although participants did not engage in explicit evaluation of the faces, the amygdala response changed as a function of face trustworthiness.
From affective value to decision‐making in the prefrontal cortex
Functional magnetic resonance imaging was used to measure activations produced by pleasant warm, unpleasant cold, and affectively complex combinations of these stimuli applied to the hand to investigate whether these are separable processes.
Does Rejection Hurt? An fMRI Study of Social Exclusion
A neuroimaging study examined the neural correlates of social exclusion and tested the hypothesis that the brain bases of social pain are similar to those of physical pain, suggesting that RVPFC regulates the distress of socialclusion by disrupting ACC activity.
Cold and Lonely
The psychological experience of coldness not only aids understanding of social interaction, but also is an integral part of the experience of social exclusion.
