Time perspective (TP) is a pivotal cognitive process through which people perceive, interpret, and negotiate their physical and social worlds. This study identifies unique patterns in the quality of social relationships that were associated with different TP dimensions. Low support and high conflict with family characterized past-negative TP. Large networks and high support from family distinguished past positive TP. Large networks with more support and companionship from friends/acquaintances typified present hedonistic TP. Having highly supportive significant others was associated with high future TP. Multidimensional time perspective is an essential cognitive process influencing human social behavior. © Taylor & Francis Group, LLC.
