Often being an ecologically valid and a versatile tool, the detour paradigm has been used to study diverse cognitive skills like insight, social learning, inhibitory control and route planning.Due to the relative ease of administrating detour tasks, the paradigm has lately been used in large-scale comparative studies in order to investigate the evolution of inhibitory control.We also review relevant developmental studies, and those investigating the neurological underpinnings of successful detour behavior.

b Inward detour task requires locomotion detour around a V-shaped transparent/fence barrier.

c Plexiglas-hole task requires a reaching detour through one of the two holes in a Plexiglas panel placed upright between the subject and the reward.

In this paper, we review one of the oldest paradigms used in animal cognition: the detour paradigm.

The paradigm presents the subject with a situation where a direct route to the goal is blocked and a detour must be made to reach it.

He believed that detours, which required moving away from the goal in order to ultimately reach it, were good tests of whether the goal-directedness was first worked out in the mind (Köhler , Online Resource 1).

The paradigm has also been used in developmental studies on human children, and in neuropsychological studies.He tested chimpanzees, dogs and chickens when they faced a wire fence barrier with a reward on the other side.His aim was to study their potential “insight” capacities.Here we review the detour paradigm and some of its cognitive requirements, we identify various ecological and contextual factors that might affect detour performance, we also discuss developmental and neurological underpinnings of detour behaviors, and we suggest some methodological approaches to make species comparisons more robust.One of the oldest paradigms in animal cognition research involves the use of a see-through obstacle that must be detoured in order to reach the visible goal on the opposite side.First, we discuss different types of detour tasks in relation to the cognitive skills they address.We examine various factors that may influence detour behaviors, including ecological, evolutionary and task-specific factors.h Detour-choice task requires the subject to turn its back to the goal that is placed on top of a tower, and select among two poles, only one of which leads to the tower where the goal is placed ).Chickens execute better detours with horizontal grid pattern fence barriers compared to vertical grid ones, likely because the vertical grid barriers offer better goal visibility for a moving animal (Regolin et al.Moreover, the barriers come in different shapes (U-, V-, I-, L-, J-shaped) and materials.Some barriers are fully transparent (e.g., glass), and some are semitransparent (e.g., fence/mesh).
