The Hand Laterality Judgement Task (HLJT) has been used as a behavioural index of motor imagery ability for decades. In the task, the individual determines whether a picture of a hand that is rotated at different angles is right or left. Although it is generally assumed that motor imagery is used implicitly to solve the HLJT, recent work suggests that other cognitive strategies might also be triggered. In this review, we synthetise behavioural, neurophysiological and clinical evidence suggesting that in fact, two main cognitive strategies can be utilised to solve this task: motor imagery and visual imagery. Researchers and clinicians should be aware that whether people will use one strategy or the other will depend on a number of key factors. This highlights the importance of carefully analysing the underlying processes used to resolve the HLJT before using it in clinical contexts as a measure of MI ability. As MI-based processing might not always arise, the use of the HLJT as an objective index of MI ability should be considered with caution. |
