{"pk":5383,"title":"The valuation cost decreases as a function of extended exposure to a risky-choice procedure","subtitle":null,"abstract":"Several studies in  pigeons and rats have reported a predictable relation between latencies  during no-choice trials and the ulterior preference in choice trials.  The Sequential Choice Model  (SCM) was proposed in 2008 to account for these results, and more  importantly to make precise predictions about the correlation between  latency and preference. Eight male Wistar rats were exposed to 48  sessions in a risk-sensitive procedure, each session was  composed by 10 blocks of trials (2 no-choice and 4 choice trials). We  analyzed data taking latencies of response and testing the SCM’s  predictions. Our data support partially the SCM’s predictions, but a  monotonic decrease to a floor effect in all latencies  of response does not allow confirming all predictions. The results are  discussed regarding a decrease in the valuation cost as a result of  extended exposure, and arguing that diminishing latencies in this  particular procedure contributed to increase the whole  rate of reinforcement.","language":"en","license":{"name":"Creative Commons Attribution 4.0","short_name":"CC BY 4.0","text":"Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.
