Where were those rabbits? A new paradigm to determine cerebral lateralisation of visuospatial memory function in children.

Groen MA, Whitehouse AJ, Badcock NA, Bishop DV - Neuropsychologia (2011)

Bottom Line: In a group of 24 adults we found this child-friendly version gave similar results to the original version of the task.In addition, fourteen children aged 6-8 years successfully completed the child-friendly fTCD task, showing a negative lateralisation index, indicating right hemispheric specialisation at the group level.Additionally, we assessed effects of task accuracy and reaction time on the lateralisation index.

Single-trial data for the LI for individuals categorised as showing right-lateralised activation on the Rabbits task, across trials at which: adults located ≤67, 83 or 100% of rabbits correctly (left panel), or children located ≤50, 75 or 100% of rabbits correctly (right panel). Each dot represents the LI on a single trial. Horizontal lines indicate the mean LI at a particular accuracy level. The number of trials included at a given accuracy level are in parentheses.

Mentions: Second, we assessed associations between task accuracy and the direction and size of the LI. No differences in accuracy were found between people who were right- or left-lateralised on the respective tasks (Circles: t(20) = 0.02, p = .984; Rabbits: Avg t(22) = 1.21, p = .238, Tac t(22) = 1.62, p = .119). On the single-trial level for people who showed right-lateralised activation, no significant differences in the size of the LI were found at different accuracy levels (H(2) = 2.05, p = .359; Fig. 3).
