The effects of an interdisciplinary infant stimulation—parent education intervention program upon infant development

An eight month infant-stimulation/parent-education program was presented to mother-child dyads participating in one of three types of classes: a structured twenty-two session group, an unstructured twenty-two session group, or a structured eleven session group. Infants (2–15 months) in all intervention groups as well as those from a control group were tested three times (pre-test, mid-test, post-test) during the course of the program using the Bayley Mental Test of Infant Development and the Uzgiris-Hunt Ordinal Scales of Psychological Development. Results tend to indicate that the intervention strategy was an effective method of parent education in enhancing infant gains on developmental indices. The results are discussed in relation to a preventative psychotherapeutic model.     

Reaction times as a measure of uncertainty

In this article, a method is presented to analyse relationships between detection or discrimination frequencies and reaction times in psychophysical tasks. It is shown in three empirical data sets that reaction time decreases as a linear function of the absolute value of the logit transforms of the response probabilities. Such a function stresses the characteristic uncertainty associated with subjects' responses and the relation between their response parameters and the response criterion used by the subjects.
