Individuals with higher magical ideation (MI) showed inconsistent arm folding and hand clasping preferences. This suggests a link between cognitive style and lateralized bodily asymmetries, potentially indicating reduced hemispheric specialization.

Area of Science:

  • Cognitive Neuroscience
  • Psychology
  • Human Behavior

Background:

  • Inconsistent postural preferences have been noted in psychiatric groups.
  • Lateralized body posture preferences, such as arm folding and hand clasping, are common but their cognitive correlates are not fully understood.

Purpose of the Study:

  • To investigate the relationship between magical ideation (MI) and postural preferences in healthy individuals.
  • To explore potential links between cognitive styles and lateralized limb asymmetries.

Main Methods:

  • Assessed arm folding (AF) and hand clasping (HC) postures in 361 healthy right-handed adults.
  • Measured varying degrees of magical ideation (MI) within the participant group.
  • Analyzed the association between congruent/incongruent postural combinations and MI scores.

Main Results:

  • Most subjects preferred congruent postures (left-arm-top AF, left-thumb-top HC).
  • Incongruent postural combinations, especially right-arm-top AF with left-thumb-top HC, were associated with higher MI scores.
  • A significant association was found between MI and lateral preferences for limb postures, varying across body parts.

Conclusions:

  • Magical ideation is associated with specific patterns of lateralized postural preferences.
  • Inconsistent limb posture asymmetries may reflect reduced hemispheric asymmetries, potentially linked to schizotypal personality traits.
