Detour behaviour in attack-trained dogs: Left-turners perform better than right-turners.
Detour behaviour was investigated in attack-trained dogs faced with a “U”-shaped vertical barrier behind which a figurant (target) was located. Left-turners took less time to detour the barrier than right-turners. The most logical explanation for the lateral asymmetries observed in dogs’ detour beha...

Left-turners took less time to detour the barrier than right-turners. The most logical explanation for the lateral asymmetries observed in dogs’ detour behaviour is to assume that they reflect preferential use of the right or the left eye in visual analysis of the target. Given that the lateral field of each eye of dogs projects mainly to the contralateral side of the brain, shorter latencies to solve the task observed in left-turners (right visual hemifield) with respect to right-turners (left visual hemifield) are consistent with specialisation of the left hemisphere in prey-catching behaviour. Overall our results supported previous evidence that cerebral lateralisation in vertebrates can directly affect visually guided motor responses and have practical implications for personnel involved in the selection of dogs trained specifically to assist police and other law-enforcement personnel in their work. pubtype: Academic Journal doctype: Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
