Abstract
We identified the important micro-relations that are perceived when attempting to recognize patterns in stimuli consisting of multiple dynamic objects. Skilled and less-skilled participants were presented with point light display sequences representing dynamic patterns in an invasion sport and were subsequently required to make familiarity based recognition judgments in three different conditions, each of which contained only a select number of features that were present at initial viewing. No differences in recognition accuracy were observed between skilled and less-skilled participants when just objects located in the periphery were presented. Yet, when presented with the relative motions of two centrally located attacking objects only, skilled participants were significantly more accurate than less-skilled participants and their recognition accuracy improved further when a target object was included against which these relative motions could be judged. Skilled participants can perceive and recognize global patterns on the basis of centrally located relational information.
Highlights
The ability to perceive and recognize patterns between features is critical in allowing humans to function and interact in a range of activities
We examined if skilled performers could perceive and recognize global patterns in displays that contained multiple objects on the basis of localized patterns and micro relations between limited numbers of display features
In light of the above findings, we were interested in testing whether the relative motion information between localized display features in dynamic stimuli was sufficient to recognize a larger pattern and, if so, whether relationships between certain display features provided more important information than other sources
Summary
The ability to perceive and recognize patterns between features is critical in allowing humans to function and interact in a range of activities. It is most apparent in allowing people to interact socially as they quickly and effortlessly recognize patterns between facial features to judge whether others are familiar or strangers (Want et al, 2003) and to judge affect and emotion (Bassilli, 1978, 1979). Chase and Simon (1973) subsequently replicated this finding but reported that when chess pieces were arranged randomly, the expert advantage was lost and memory performance was no different to Recognizing Dynamic Patterns that observed for less-skilled players. The results indicated the experts did not possess superior generic memory per se, but rather as a result of extended practice they developed domain specific knowledge structures which underpinned their expertise in the particular domain (Ericsson et al, 2009)
