Although decision-making processes are typically studied with isolated individuals in the laboratory to control external factors, we mostly make decisions in a social environment in the presence of other individuals. The aim of the current study was to investigate the effects of social conditions on individuals' decision-making performance in economic and moral contexts. Forty-four pairs of participants of the same gender (42 females and 46 males) constituted the sample for this study. Each pair was required to complete both economic and moral tasks under three types of social conditions, namely, “individual,” “joint,” and “joint with gaze-cueing.” Furthermore, eye- and mouse-tracking technologies were utilized to record the participants' responses to the decision tasks. We hypothesized that even a minimal social context would influence people's decisions, as manifested in their gaze and mouse responses. The results revealed that the minimalist social condition in which participants do not communicate or interact with each other affected their decision-making performance. The interplay among social conditions, diverse task types, and stimuli type were identified as some of the factors that impact the decision-making process in this setting.
