Md. Lucas et al., LATERALITY OF CRADLING IN RELATION TO PERCEPTION AND EXPRESSION OF FACIAL AFFECT, The Journal of genetic psychology, 154(3), 1993, pp. 347-352
A dominant leftward cradling bias has been observed in women in non fe
eding interaction with infants. Reasons tor this behavior have been so
ught in behavioral asymmetries, but none have sufficiently justified t
he presence of this leftward pattern. Recently, the cradling bias has
been linked to affective processing, considered to be a specialized fu
nction of the nondominant (right) hemisphere (Manning & Chamberlain, 1
990). This study investigates Manning and Chamberlain's (1990) suggest
ions that a relationship exists between leftward cradling and the inte
rpretation and expression of affect. Eighty-six nulliparous women were
tested for this relationship by correlating direction of cradling bia
s with visual field dominance for perception of facially expressed emo
tion and expression of affect. No significant relationship was found t
o directly support the hypotheses.
