Both the amount of relearning sessions and the number of days in between each session have a major impact on retention (the repetition effect and the spacing effect ...
A 2016 study by Kumar et al. [13] chemically analyzed these secretions, concluding that they may be required in chemosensory mediated communication [14] and mate choice. Similarly, in the less aggressive herb-field mouse, males are observed to groom females for longer durations and even allow females to not reciprocate. [ 15 ]
