Spatial location judgements by right and left-handers.
An attempt was made to replicate the left-hand advantage found by Roy and Mackenzie (1978) for a bimanual thumb-positioning task. As in their experiment strongly right-handed male and female subjects took part, and in addition strongly left-handed male and female subjects took part. Their findings were not fully replicated. A weak left-hand advantage was found for only one of the three error measures used (constant error). Significant interactions of sex with handedness were found for absolute and constant error. The difficulty of replication and current findings are discussed in terms of possible variations in subject strategy which warrant further investigation.
