The ability to track moving objects is a crucial skill for performance in everyday spatial tasks. The tracking mechanism depends on representation of moving items as coherent entities, which follow the spatiotemporal constraints of objects in the world. In the present experiment, participants tracked 1 to 4 targets in a display of 8 identical…

Patients with traumatic brain injury show clear impairments in behavioural flexibility and inhibition that often persist beyond the time of injury, affecting independent living and psychosocial functioning. Functional magnetic resonance imaging studies have shown that patients with traumatic brain injury typically show increased and more broadly…

Three studies were conducted to examine the relation of spatial visualization to solving kinematics problems that involved either predicting the two-dimensional motion of an object, translating from one frame of reference to another, or interpreting kinematics graphs. In Study 1, 60 physics-naive students were administered kinematics problems and…

The accuracy and bias of estimates of whisker length based on box, line, and midgap plots were examined. For each type of graph, 20 different undergraduates (n=60) viewed 48 single-plot graphs. Whisker-length estimates for box and line plots were more accurate and less biased than those for midgap plots. (TJH)

To study graphic representation in different cultures, 1,279 children, adolescents, and university students from English, Hebrew, and Arabic language cultures produced graphic representations of spatial, temporal, quantitative, and preference relations in three experiments. Findings are discussed in relation to subjects' age and language culture.…
