The effect of different ratios of practice (observation of action, motor imagery and combined training) on the consolidation of motor memory of girl children: a challenge to the cognitive load hypothesis

Efforts to further progress in practice and learning have introduced cognitive imagery and action observation. The aim of this study was to investigate the effect of different practice ratios on consolidation the motor memory of girls with cognitive load. This research was a quasi-experimental study with a pretest, acquisition and retention design. The statistical population of the study includes primary school students in the 18th district of Tehran in the academic year of 97-98 who were selected by convenience sampling method. 98 elementary school girl students in the age range of 8-12 years were randomly divided into 10 groups (physical practice, motor imagery, action observation, motor imagery - physical practice and action observation - physical practice) based on inclusion criteria. Were. Demographic, motion imaging (MIQ-R) and motion imaging resolution (VMIQ-2) questionnaires, Strope task and serial color matching task were used to collect information. Participants made an effort in the 1920 acquisition phase and 48 hours later in an 80-block memorial session. To analyze the data, analysis of covariance test 2 (assessment steps: acquisition, retention) × 5 (experimental groups) with repetition on the factor of assessment steps, SPSS software was used. The results of analysis of variance showed that the main effect of practice type and cognitive load type was significant (p <0.05). The results of Bonferroni post hoc test showed that the participants in the practice observation and imaging group with low cognitive load had the best performance and the participants in the practice group with low cognitive load had the weakest performance compared to the other groups. Performing practice in a combination of observation and imaging will lead to better performance in learning and consolidation motor memory.
