Interactions between homogeneous conditioned motor reflexes during conditioned reflex switching: transfer of learning and interference.

Studies in rabbits of the time course of the formation of conditioned reflex switching of homogeneous reflexes showed that learning involved three main stages, characterized by the extent of stability of the conditioned reflexes, their interaction, and the level of switching. Formation of conditioned reflex switching was found to involve transfer of motor learning and interference of motor reflexes.

[The interaction of homogeneous motor conditioned reflexes during conditioned-reflex switchover: the transfer of learning and interference].

The dynamics of elaboration of the conditioned switchover (CSw) of homogeneous motor conditioned reflexes (CR) with different lateralization of the motor skill was studied in rabbits. Learning of CSw was shown to pass three basic stages characterized by different degree of consolidation of the CRs, by interaction between the two CRs, and by manifestation of CSw. Stages I and II reflected the process of afferent and efferent generalization of CRs and CSw, stage III was associated with specialization of CRs and CSw. Both positive and negative transfer of motor learning as well as interference between the two motor skills took place during CSw elaboration. The highest rate of CSw acquisition was observed in rabbits displaying positive motor transfer.

[The statistical evaluation of the reliability of learning curve differences].

A nonparametric method of statistical analysis of two related binary sequences of "1" and "0" is presented. This technique enables comparison between the dynamics of probability of appearance of 1" in the two sequences. This test can be applied to the problem of statistical comparison between the dynamics of learning of a "stimulus-reaction" type when the appearance of reaction to the stimulus is labeled as "1" and its absence as "0". The graphical interpretation is given and IBM-PC/AT program is characterized which realizes the advanced method.
