The authors propose a general modeling framework called the general monotone model (GeMM), which allows one to model psychological phenomena that manifest as nonlinear relations in behavior data without the need for making (overly) precise assumptions about functional form. Using both simulated and real data, the authors illustrate that GeMM…

This study sought to test the most efficient representation mode with which children with hearing impairment could express a story while producing connectives indicating relations of time and of cause and effect. Using Bruner's (1973, 1986, 1990) representation stages, we tested the comparative effectiveness of Virtual Reality (VR) as a mode of…

Children with mental retardation have pronounced difficulties in using cognitive strategies and comprehending abstract concepts--among them, the concept of sequential time (Van-Handel, Swaab, De-Vries, & Jongmans, 2007). The perception of sequential time is generally tested by using scenarios presenting a continuum of actions. The goal of this…

Compares the ages at which infants living under different conditions in two orphanges in Athens, Greece achieve levels of object construction and imitation, both verbal and gestural. Home-reared infants of the same age range were also examined using two of the Uzgiris-Hunt Ordinal Scales of Infant Psychological Development. (WY)

To compare the adolescent's mode of thinking on one specific measure of cognition, conservation of volume, with his mode of thinking on a task simulating a familiar real-life situation, a study was made using 162 students (76 males and 86 females, 13.4 to 17.7 years of age, grades 7,8,9,10,12). The students, grouped according to age into four…
