DESCRIPTION:Wei-Hsiang Lin\, BMI\nHybrid by invitation only.\n\nMaking dec
 isions is one of the most crucial tasks in our daily lives. Several factor
 s possibly affect how one makes decisions. For example\, social dominance 
 orientation (SDO)\, a personality trait reported to be associated with lea
 dership\, may play an important role. Here\, we investigated how SDO shape
 s decisions in a variety of decision-making tasks by exploring how several
  behavioral patterns were associated with the dominance trait. We recruite
 d 146 participants via the online platform Prolific. Each participant comp
 leted seven questionnaires to measure their dominance and personality trai
 ts as well as six different cognitive tasks. The tasks captured a wide var
 iety of decision-making scenarios such as value-based (lottery choice task
 )\, perceptual-based (emotion discrimination task) decisions\, and goal-di
 rected behavior (reinforcement learning). Additionally\, two control tasks
  (Go No/Go task and simple reaction time task) were used to measure execut
 ive function and motor speed. Firstly\, we found a negative correlation be
 tween the dominance trait and reaction time of decision-making tasks\, sug
 gesting a predisposition for high dominant individuals to act faster. No c
 orrelation was found for the control tasks\, suggesting that the fast reac
 tions of dominant individuals in decision-making tasks are not merely expl
 ained by superior motor ability or increased impulsivity. Additionally\, t
 here was no significant relation between dominance trait and accuracy or o
 ther decision-related variables\, such as risk aversion\, reward discounti
 ng\, or the proportion of making optimal actions in the reinforcement lear
 ning framework. Hence\, high dominance individuals outperform those of low
  dominance individuals in making decisions in terms of speed\, which does 
 not pertain to their motor or executive abilities. Comparatively\, high do
 minance individuals do not demonstrate superior performance or display uni
 que strategies across a wide range of decision-making scenarios.\n
