Webb1 juli 2024 · Some studies suggest probabilistic learning may be inefficient in youths compared to adults, while others suggest it may be more efficient in youths in mid adolescence. Here we used a probabilistic reinforcement learning task to test how youth age 8-17 (N = 187) and adults age 18-30 (N = 110) learn about stable probabilistic … Webb2 mars 2024 · Study 1: Probabilistic reward learning performance increases during adolescence We collected developmental data from human participants on a well-characterised 3-choice probabilistic decision-making task ( Fig 1) adapted from paradigms previously used in macaques and adult humans [ 6, 14, 16, 22, 49 ].
Impairment of probabilistic reward-based learning in schizophrenia.
WebbIn reinforcement learning, rewards capture the notion of short-term gains. The objective of an agent, however, is to learn a policy that maximizes the cumulative long-term reward. … Webb8 maj 2024 · Subjects completed trials of a probabilistic reward learning task which involved choosing one of two stimuli. During the first phase of each trial a cue indicated whether participants would be allowed to freely make a choice between the two squares or whether the computer would choose for them and they had to follow that choice. companies that don\u0027t advertise
