The effect of environmental enrichment with autistic-like behavior symptoms on a rattus norvegicus model

AIM: The aim of this study was to investigate the effect of environmental enrichment with autistic-like behavior symptoms on a Rattus norvegicus model. METHODS: The post-test control only group design is used in this study. The study sample is baby of Rattus norvegicus Sprague Dawley strain who were born to cows who gave birth for the 1^st time and children from cows who had been injected with valproic acid (VPA) who gave birth for the 1^st time. This study has been divided into three groups, namely, negative control, positive control, and intervention: the negative control group; the VPA without enrichment as positive control; and the VPA group with enrichment as intervention group. One-way ANOVA tests were used to data analysis. Data are processed using SPSS version 23.0. RESULTS: This study showed that the mean of social interaction in the negative control group was 359.11 ± 39.33 s higher than the positive control, namely, 182.00 ± 35.80 s and 244.56 ± 19.06 s for intervention. The mean of repetitive movement in the negative control group was 48.00 ± 9.03 s lower than the positive control, namely, 212.11 ± 41.43 s and intervention 160.00 ± 18.91 s. There has been an influence of environmental enrichment with social interaction and repetitive movements on a Rattus norvegicus model (p < 0.05). CONCLUSION: This study confirmed that there has been an influence of environmental enrichment with social interaction and repetitive movements on a Rattus norvegicus model.
