Mental Rotation: The Effects of Processing Strategy, Gender and Task Characteristics on Children's Accuracy, Reaction Time and Eye Movements’ Pattern

The effects of gender, strategy and task characteristics on children's mental rotation
(MR) behavioral measures and eye movements were studied. Eye movements reflect
thinking pattern and assist understanding mental rotation performance.
Eighty-three fourth-grade children (44 boys and 39 girls) were administered the
Computerized Windows Mental Rotation test (CWMR) while having their eye
movements monitored and completed a Strategy Self-Report (global/local/combined)
and a Spatial Span (WM) subtest. Difficulty level affected performance and
was reflected in a different eye movement pattern. Boys were more accurate than
girls, but they did not differ in their eye movement pattern. Eye movement pattern
was related to strategy, accuracy and reaction time, revealing that the global and
combined strategy were more effective compared with local strategy. WM was
found to correlate with accuracy at the easy level of the test. The usage of eye
movement measures assists in elaborating our knowledge regarding MR performance
among children and enable a wider understanding regarding the interaction
between gender, strategy and difficulty level.
