Space-time interference: The asymmetry we get out is the asymmetry we put in

Area of Science:

• Cognitive Psychology
• Neuroscience
• Perception

Background:

• Temporal judgments are often more influenced by spatial factors than vice versa.
• This asymmetry is commonly interpreted as spatial representations having primacy over temporal ones, aligning with conceptual metaphor theory.
• However, this contradicts the idea of a common neuronal magnitude system.

Purpose of the Study:

• To review evidence for symmetric interference between time and space perception.
• To explore explanations for asymmetric interference, specifically regarding spatial size/temporal duration and distance traveled/travel time.
• To challenge the notion of hierarchical representations of time and space.

Main Methods:

• Review of existing empirical evidence on the interaction between spatial and temporal magnitude processing.
• Analysis of experimental paradigms and stimuli used in studies of time-space interactions.
• Theoretical discussion integrating working memory and stimulus-driven factors.

Main Results:

• Accumulating evidence supports a genuinely symmetric interference between time and space.
• Asymmetric interference can arise from working memory processes and the inherent speed of dynamic stimuli.
• The observed asymmetry (space affecting time more than vice versa) is likely due to biased experimental designs and stimuli.

Conclusions:

• The interaction between time and space perception is fundamentally symmetric.
• Asymmetries in interference are not indicative of hierarchical representations but rather methodological artifacts.
• Future research should consider the impact of experimental design on perceived time-space interactions.
