Developmental Psychology on Dynamic Systems - Dictionary of Arguments

Upton I 56
Dynamic System Theory/Developmental psychology/Upton: Smith et al. (1999)(1) (…) argue that, although successful completion of the >A-not-B task does suggest a qualitative change in infant behaviour, this change in behaviour actually represents a number of quantitative changes in a complex dynamic system. The A-not-B error is explained in terms of general processes of goal-directed reaching; the erroneous reach back to A is seen as the result of a number of processes that enable the infant to look, discriminate locations, control their posture and plan a motor response. All these processes are brought together and self-organised by the task of reaching for a particular object in a particular context. In this perspective, behaviour and cognition are not separate and there are no causal mechanisms, such as an object concept, that generate a thought or behaviour. In this model what we commonly call knowledge and concepts are distributed across and embedded in behavioural processes.
