As a dual behavioral and computational neuroscience research project, this study first tested reproductive effects on attention, learning, and decision making using the Attentional Set-Shifting Task (AS-ST) and then a Machine Learning model was constructed to simulate perceptual judgments and decision making through reinforced learning. In the behavioral task, response times and errors from 5 primiparous (one-time mothers) and 4 nulliparous (never pregnant) Sprague-Dawley rats were recorded during four increasingly complex attention modulation and paired associative learning tasks. The Machine Learning model reconstructed each task's decision problems through representation of internal and external conditions, valuation, action, and outcome evaluation to …
