| Summary: | The present study was designed to investigate the role of motor response programming in the CI effect using the framework of the two-process model for programming (Klapp, 1996). Experiment 1 evaluated programming demands during random practice for single-element "dit'' and "dah'' Morse code responses with a self-select paradigm. It was shown that study time (ST) but not reaction time (RT) was influenced by the duration of the response. These findings indicated that the time to preprogram a response (i.e. ST) was a function of the duration of the response element while the time to sequence the response (i.e. RT) was not. Experiment 2 evaluated the demands of programming the duration of a response under random and blocked practice. ST was influenced by the duration of the response element only during random practice. This was interpreted to mean that programming processes associated with the duration of a response are bypassed during blocked practice. Neither the duration of the response or the practice schedule influenced RT. This was interpreted to mean that the practice groups handle sequencing demands of a single-element response equally. Experiment 3 investigate how single-element and four-element responses influenced ST and RT during random practice. The number of elements in the response influenced both ST and RT indicating that four-element responses place a higher demand on programming response element durations as well as on sequencing the elements of a response. Experiment 4 investigated the demands of programming responses that differed with respect to the number of elements during random and blocked practice. The number of elements in a response had a greater influence on ST during random practice than during blocked practice. This was interpreted to reflect the fact that blocked practice allows the processes associated with programming response element durations to be bypassed. The number of elements also influenced RT but this was equally so across practice conditions. Thus, the demands of sequencing single-element and four-element responses were handled equally by random and blocked practice. These results are discussed with regard to the CI effect as well as their significance for the motor response programming literature. |
