“…On the contrary, our results showed no evidence that biases change linearly during childhood when the mean age of the participants was entered as a moderator variable. However, the study with the youngest mean age was 5.6 years (De Agostini et al 1999), which is already within the age range where spatial biases are believed to emerge, and so we are unable to conclude whether children younger than this have a spatial bias (Bradshaw et al 1988;De Agostini et al 1999;Failla et al 2003;Girelli et al 2017;Hausmann et al 2003;Hoyos et al 2020;Patro et al 2018). We would encourage researchers to provide separate data for children at each year of age so that a more accurate picture of developmental trajectories in early childhood can be identified in future studies.…”

“…2) Sex: Six studies reported separate data for girls and boys (Asenova and Andonova-Tsvetanova 2019;Chokron and De Agostini 1995;De Agostini et al 1999;Dellatolas et al 1996;Hoyos et al 2020;van Vugt et al 2000). Due to the small number of studies that reported separate data for boys and girls, we also calculated the percentage of male participants in each study where this data was available (11 studies did not report this data and were excluded from this analysis: Boles et al 2009;Dennis et al 2005;Girelli et al 2017;Hausmann et al 2003;Ickx et al 2017;Liu et al 2012;Michel et al 2011;Ninaus et al 2017;Roeltgen and Roeltgen 1989;Rolfe et al 2008;Sheppard et al 2002).…”

“…In children, leftward line bisection biases are often observed from around 5-7 years of age (Bradshaw et al 1988;De Agostini et al 1999;Failla et al 2003;Girelli et al 2017;Hausmann et al 2003;Hoyos et al 2020), but there is little evidence of a bias to either side of space in children younger than this (Patro et al 2018). The gradual maturation of the corpus callosum during childhood has been touted as an explanation for this phenomenon, a structure which promotes the integration of perceptual information across the left and right cerebral hemispheres (Pulsipher et al 2009).…”

“…Alternatively, the development of pseudoneglect in later childhood may, at least partially, be related to cultural factors, such as reading direction (Chokron and De Agostini 1995). The development of reading skills during this period of childhood, and in particular the requirement to initially attend to the left side of a word or sentence, could be a driving factor in the development of leftward biases in native left-to-right reading children (Hoyos et al 2020).…”

Young adults exhibit a subtle, group-level asymmetry of lateral spatial attention favouring the left hemispace over the right (pseudoneglect). We have recently shown that leftward biases are maintained in older adults aged ≥50 when measured using the line bisection task (Learmonth and Papadatou-Pastou 2021). Here we present a meta-analysis of spatial biases in children aged ≤16 years. Databases (PsycINFO, Web of Science, and Scopus) and pre-print servers (bioRxiv, medRxiv, and PsyArXiv) were searched up to 8th March 2021 for studies involving children aged ≤16, who were tested using the line bisection or landmark task, and who had not been recruited as an atypically developing group. Thirty-six datasets from 33 studies, involving 2515 children, were included. A small leftward bias was identified overall (Cohen’s d = -.18, 95% CI = -.36, -.01). No spatial bias was identified when the 33 line bisection studies were analysed separately (d = -.16, 95% CI = -.35, .04). Moderator analysis of the line bisection task found a strong influence of the hand that was used to bisect the line, with right-handed actions resulting in right-biased bisections, and left-handed actions in left-biased bisections (symmetrical neglect). Bisections were slightly more leftward in studies that included a higher percentage of boys relative to girls. Age, hand preference, and the control group status of the children did not moderate spatial biases and we found no evidence of small study publication bias. However, the number of studies included in each moderator analysis was small. This meta-analysis confirms that pseudoneglect is present in children, but its detection is dependent on the task that is used.

Developmental changes in neural lateralization for visual‐spatial function: Evidence from a line‐bisection task

Studies of hemispheric specialization have traditionally cast the left hemisphere as specialized for language and the right hemisphere for spatial function. Much of the supporting evidence for this separation of function comes from studies of healthy adults and those who have sustained lesions to the right or left hemisphere. However, we know little about the developmental origins of lateralization. Recent evidence suggests that the young brain represents language bilaterally, with 4-6-year-olds activating the left-hemisphere regions known to support language in adults as well as homotopic regions in the right hemisphere. This bilateral pattern changes over development, converging on left-hemispheric activation in late childhood. In the present study, we ask whether this same developmental trajectory is observed in a spatial task that is strongly right-lateralized in adults-the line bisection (or "Landmark") task. We examined fMRI activation among children ages 5-11 years as they were asked to judge which end of a bisected vertical line was longer. We found that young children showed bilateral activation, with activation in the same areas of the right hemisphere as has been shown among adults, as well as in the left hemisphere homotopic regions. By age 10, activation was right-lateralized. This strongly resembles the developmental trajectory for language, moving from bilateral to lateralized activation. We discuss potential underlying mechanisms and suggest that understanding the development of lateralization for a range of cognitive functions can play a crucial role in understanding general principles of how and why the brain comes to lateralize certain functions.

Development of laterality: Asymmetrical human behaviors and perceptual biases

Many asymmetries characterize human functioning at the behavioral level, such as handedness (right-handedness, left-handedness, mixed-handedness) and the cerebral level. Atypical laterality is frequently mentioned in scientific literature as part of the clinical picture of several neurodevelopmental and psychiatric disorders. Thus, understanding the neurodevelopmental mechanisms underlying laterality could shed light on the etiology of cognitive and motor difficulties. The goal of this thesis is twofold. Firstly, the theoretical objective was to investigate the involvement of the prenatal environment in the development of handedness. The influence of the vestibular system, fetal presentation, and other perinatal factors related to pregnancy complications and birth stressors were tested. Our results show no influence of the fetal presentation on the subsequent development of handedness. Perinatal adversities such as prematurity, low birthweight, and poor neonatal health reflected by very low Apgar scores however, appear to be risk factors which increase the prevalence of atypical handedness and motor impairments. Secondly, the applied objective was to simultaneously detect the different perceptual biases implicated in graphomotor productions. A 3D-2D transcription graphic task was proposed for identifying global patterns of drawing asymmetries, underpinned by cerebral lateralization, biomechanical constraints, and sociocultural influences. Our results suggest that cerebral lateralization, modulated by handedness and sex, influence graphomotor asymmetries in both children and adults. However, this influence is weaker in adults, which could be due to sociocultural influences.
