This study was designed to look at the differences in visuospatial abilities between boys and girls before they can speak fluently. At the mandatory two year follow up visit, children were given the opportunity to build a tower and a bridge. In children whose birth weight was > or = 2500 g, the capacity for erecting a tower was the same in both sexes, but for building a bridge striking differences were noted according to their sex. Among the 376 children of this category, 41 out of 199 boys (21%) were able to build a bridge in comparison with 15 out of 177 girls (8%). This difference is highly significant. In children whose birth weight was < or = 2500 g, no differences were noted either for building a tower or a bridge. By showing that boys outnumber girls among the most skilled toddlers in spatial abilities, this work confirmed the action of a male related factor on cerebral lateralisation.
本研究旨在观察男孩和女孩在能够流利说话之前视觉空间能力的差异。在强制性的两年随访中，让孩子们有机会搭建一座塔和一座桥。对于出生体重≥2500克的儿童，搭建塔的能力在两性中相同，但在搭建桥方面，根据性别观察到了显著差异。在这一类别的376名儿童中，199名男孩中有41名（21%）能够搭建桥，而177名女孩中有15名（8%）能够搭建桥。这种差异非常显著。对于出生体重≤2500克的儿童，在搭建塔或桥方面均未观察到差异。通过表明在空间能力最熟练的幼儿中男孩数量多于女孩，这项研究证实了男性相关因素对大脑侧化的作用。
