J. Kounios et Rw. Smith, SPEED-ACCURACY DECOMPOSITION YIELDS A SUDDEN INSIGHT INTO ALL-OR-NONEINFORMATION-PROCESSING, Acta psychologica, 90(1-3), 1995, pp. 229-241
The existence of discrete all-or-none information processing has often
been assumed as a basis for stage models and also as an important cha
racteristic of nonlinear connectionist models; however, there has been
little or no hard empirical evidence supporting the existence of this
phenomenon. In search of such evidence, we applied speed-accuracy dec
omposition (Meyer et al., 1988), a technique for detecting partial res
ponse information, to the examination of the time-course of processing
in a (Gestalt) insight-like task, namely, anagram solution. This task
was chosen because the Gestalt psychologists conjectured that insight
is a sudden, discrete phenomenon. Supporting this view, we found litt
le or no evidence of partial information in two experiments, thereby p
roviding what may be the strongest evidence to date for all-or-none pr
ocessing.
