We tested the effect of a Rotated Protocol Immersion package on the emergence of observing responses as prerequisites for more complex verbal developmental capabilities. Three elementary aged students between the ages of 6 and 7 participated. They were diagnosed with autism spectrum disabilities. The treatment condition consisted of total…

To investigate the attributional processes mediating between outcome and expectancies and persistence, children's expectancies, attributions and response latency were measured. Children, equally divided into three age groups (three-five, six-eight, nine-twelve) were shown figures to match and were provided with experimentally controlled feedback…

Human development from about ages 2 to 5 is presented in terms of the history of a child conceptualized in terms of stimulus and response functions and his interactions in current situations which consist of organismic, physical, and social conditions. The concepts describing the changes that occur during this developmental period, such as…

Partial and methodologically questionable replications of the Luria experiments on the child's verbal regulation of his motor behavior have led to results and conclusions contradictory to Luria's findings. An error in the methodology of two of these replications is discussed as the reason for a new investigation of Luria's hypothesis. Several…
