Theory suggests that the vision-for-perception and vision-for-action processing streams operate under very different temporal constraints (Glover, 2004; Goodale, Jackobson, & Keillor, 1994; Graham, Bradshaw, & Davis, 1998; Hu, Eagleson, & Goodale, 1999). With the present study, children and young adults were asked to estimate how far a cued target…

The study sought to provide norms for a simple test of visual perception of verticality (subjective visual vertical). The study was designed as a cohort study with a balanced design. The setting was the Rehabilitation Department of a University Hospital. Twenty-two healthy adults, of 23-58 years, 11 men (three left handed) and 11 women (three left…

Two experiments were reported that aimed at investigating the development of spatial analysis of hierarchical patterns in children between 3 and 9 years of age. A total of 108 children participated in the drawing experiment, and 224 children were tested in a force-choice similarity judgment task. In both tasks, participants were exposed to…

Children ages 4, 6, and 8 years and adults performed self-selected, continuous, unimanual and bimanual coordination tasks for 30 s. The length of time performing the task was investigated as a potential control parameter. As hypothesized, all groups spent less time in antiphase than in in-phase coordination as the trial continued. These results…

We assessed 110 left-handed and 322 right-handed children aged from 3 to 10 years, using Bishop's card-reaching task. Manual body midline crossings were observed. A regular developmental trend was observed from 3 to 10 years: older children crossed the body midline more frequently when reaching for cards than did younger children. The factor age…
