Static hand postures influence spatial-numerical associations (SNAs), like the SNARC effect, even when using feet for responses. This suggests bodily states impact number-space mappings.

Area of Science:

  • Cognitive Psychology
  • Embodied Cognition
  • Neuroscience

Background:

  • Spatial-numerical associations (SNAs), exemplified by the SNARC effect, link smaller numbers to the left and larger numbers to the right.
  • SNAs are adaptable, influenced by sensorimotor experiences, particularly in hand-based tasks.

Purpose of the Study:

  • To investigate how static hand posture, independent of motor execution, affects the SNARC effect using a foot-response paradigm.
  • To test the embodied cognition hypothesis that passive postural cues can bias spatial-numerical mappings.

Main Methods:

  • 103 participants performed a digit magnitude classification task using foot pedals.
  • Hand posture was manipulated (fingers interlaced, palms down, palms up) as a task-irrelevant cue.
  • A foot-response paradigm was employed to isolate postural effects from motor execution.

Main Results:

  • Significant SNARC effects were observed in the palms-down and palms-up hand posture conditions.
  • No significant SNARC effect was found in the control (fingers interlaced) condition.
  • Numerical distance effects were consistent across all postural conditions.

Conclusions:

  • Static bodily configurations, even when task-irrelevant, can modulate spatial-numerical associations.
  • These findings support embodied cognition theories, showing current sensorimotor states influence numerical cognition.
  • Foot-based response paradigms offer a valuable method for dissociating postural influences from response modality in SNA research.
