Subclaims¶

q2 i? No significant overall group effect was observed on view-invariant object recognition, but EH mice showed a significant preference for the rotated object whereas the OC group explored rotated and non-rotated objects equally. → Gattas 2022

q2 · i? · causal · r2

View-invariant object recognition experiment (sample 10 min, 5-min delay) 3 months post-enrichment in the four-group design. The ANOVA group effect was not significant, F(3, 36) = 1.468, p = 0.240, partial η2 = 0.109; only the EH-vs-novelty contrast was tested significantly.

"The OC group, to the most extent (numerically), treated both rotated and non-rotated objects as familiar, exploring them equally (Fig. 5d). Conversely, a paired-samples t-test showed that the EH group displayed a preference for the rotated object, suggesting that this group tended to perceive the rotated object as novel t(9) = −3.046, p = 0.014."
