To each their own: a review of individual differences and metaphorical perspectives on time

Approaching future rewards or waiting for them to arrive: Spatial representations of time and intertemporal choice

Our mental representation of the passage of time is structured by concepts of spatial motion, including an ego-moving perspective in which the self is perceived as approaching future events and a time-moving perspective in which future events are perceived as approaching the self. While previous research has found that processing spatial information in one's environment can preferentially activate either an ego-moving or time-moving temporal perspective, potential downstream impacts on everyday decision-making have received less empirical attention. Based on the idea people may feel closer to positive events they see themselves as actively approaching rather than passively waiting for, in this pre-registered study we tested the hypothesis that spatial primes corresponding to an ego-moving (vs. time-moving) perspective would attenuate temporal discounting by making future rewards feel more proximal. 599 participants were randomly assigned to one of three spatial prime conditions (ego-moving, time-moving, control) resembling map-based tasks people may engage with on digital devices, before completing measures of temporal perspective, perceived wait time, perceived control over time, and temporal discounting. Partly consistent with previous research, the results indicated that the time-moving prime successfully activated the intended temporal perspective-though the ego-moving prime did not. Contrary to our primary hypotheses, the spatial primes had no effect on either perceived wait time or temporal discounting. Processing spatial information in a map-based task therefore appears to influence how people conceptualise the passage of time, but there was no evidence for downstream effects on intertemporal preferences. Additionally, exploratory analysis indicated that greater perceived control over time was associated with lower temporal discounting, mediated by a reduction in perceived wait time, suggesting a possible area for future research into individual differences and interventions in intertemporal decision-making.

Spice up the moment: The influence of spicy taste on people's metaphorical perspectives on time

Embodied cognition contends that sensorimotor experiences undergird cognitive processes. Three embodied cross-domain metaphorical mappings constitute quintessential illustrations: spatial navigation and orientation underpin the conceptualization of time and emotion and gustatory sensation underlies the formulation of emotion. Threading together these strands of insights, the present research consisted of three studies explored the potential influence of spicy taste on people's metaphorical perspectives on time. The results revealed a positive correlation between spicy taste and the ego-moving metaphor for time such that individuals who enjoyed spicy taste (Study 1) and who consumed spicy (vs. salty) snack (Study 2) exhibited a predilection for the ego-moving perspective when cognizing a temporally ambiguous event. Because both spicy taste and the ego-moving metaphor are associated with anger and approach motivation, the latter two were postulated to be related to the novel taste-time relationship. Corroborative evidence for the hypothesis was found, which indicated that spicy (vs. salty) intake elicited significantly stronger anger toward and significantly greater approach-motivated perception of a rescheduled temporal event (Study 3). Taken together, the current findings demonstrate that spicy taste may play a role in people's perspectives on the movement of events in time and highlight the involved embodied interrelation between language, emotion, and cognition.
