“…Other studies have found similar pattern of results with other tasks (Marcel & Rajan, 1975;Young & Bion, 1980). Recognition tasks using chimeric faces have provided mixed results: while Roszkowski and Snelbecker (1982) found hemispheric asymmetry in children from 6 years of age, others have found it only from 10 years of age (Levine, 1981;Reynolds & Jeeves, 1978). We investigated the development of the right hemisphere advantage in face perception, gender recognition, and facial expression recognition in children between 5Á6 and 10 years of age using chimeric faces, since there is evidence to suggest the suitability of this method to examine the visual field bias from age 6 years of age.…”

Studies with adults have found a left bias in their perception of faces, which suggests a right hemisphere specialisation in processing facial information. Hemispheric asymmetry is observed during the first year of life but it is still unclear at what age such specialisation becomes adult-like during the prolonged period of face-processing development through childhood. In the present study we investigated the development of children's perceptions of gender and emotion using chimeric faces. Our results demonstrate that a right hemisphere bias, similar to that found in adults, is observed from 5 years of age. The results are discussed within a framework of developmental studies and we conclude that although children may be less efficient than adults at encoding faces, their basic manner of encoding is not fundamentally different from that of adults.

“…In this regard, it should be stressed that, whereas the leftward bias in face perception is usually observed in children of about 5 years (e.g., Roszkowski and Snelbecker, 1982 ; Levine and Levy, 1986 ; Kolb et al, 1992 ; Failla et al, 2003 ; Workman et al, 2006 ; Aljuhanay et al, 2010 ; Taylor et al, 2012 ), it is often reported to increase with age and reach an adult-like level by the age of about 10 years ( Chiang et al, 2000 ; Workman et al, 2006 ; Anes and Short, 2009 ; Balas and Moulson, 2011 ; Taylor et al, 2012 ; Watling and Bourne, 2013 ; for a review, see Watling et al, 2012 ). However, the use of different methods seems to provide data in favor of both earlier (e.g., eye tracking; Wheeler, 2010 ; Liu et al, 2011 ; Dundas et al, 2012b ) and later (e.g., moving window technique; Birmingham et al, 2012 ) emergence of an appreciable leftward bias in face processing.…”

“…However, one should not forget the possible contribution of motor representations in shaping attentional biases. In fact, the left hemispatial bias for face processing usually observed in right-handers is absent ( Jaynes, 1976 ; Heller and Levy, 1981 ; Roszkowski and Snelbecker, 1982 ; Hoptman and Levy, 1988 ) or weaker ( Luh et al, 1994 ) in left-handers. Moreover, left-handers turn out to be less affected by a leftward pseudoneglect ( Brodie and Dunn, 2005 ; see also the meta-analysis by Jewell and McCourt, 2000 ).…”

Healthy individuals tend to weigh in more the left than the right side of visual space in a variety of contexts, ranging from pseudoneglect to perceptual asymmetries for faces. Among the common explanations proposed for the attentional and perceptual advantages of the left visual field, a link with the prevalence of right-handedness in humans has never been suggested, although some evidence seems to converge in favor of a bias of spatial attention toward the region most likely coincident with another person’s right hand during a face-to-face interaction. Such a bias might imply an increased efficiency in monitoring both communicative and aggressive acts, the right limb being more used than the left in both types of behavior. Although attentional and perceptual asymmetries could be linked to right-handedness at the level of phylogeny because of the evolutionarily advantage of directing attention toward the region where others’ dominant hand usually operates, it is also legitimate to question whether, at the ontogenetic level, frequent exposure to right-handed individuals may foster leftward biases. These views are discussed in the light of extant literature, and a number of tests are proposed in order to assess our hypotheses.
