CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn their report, Lehner et al. (2017) adopt the Pavlovian-to-Instrumental Transfer (PIT) paradigm to compare the ability of different rewards to drive behavior. The PIT-tests the extent to which a Pavlovian cue (i.e., a reward-associated cue) can elicit instrumental responses independently paired with the same (specific PIT), or a similar (general PIT), reward (Garofalo and di Pellegrino, 2016). During PIT-test, instrumental responses—previously associated with a reward—are performed under extinction, while task-irrelevant Pavlovian cues are concurrently presented. The crucial question is: can an external stimulus that recalls a reward, modulate reward-seeking behavior? Such a mechanism has both adaptive (e.g., effectively providing for needed food), and maladaptive implications (e.g., looking for food even when not necessary; see Everitt et al., 2001).

| Abstract: | In their report, Lehner et al. (2017) adopt the Pavlovian-to-Instrumental Transfer (PIT) paradigm to compare the ability of different rewards to drive behavior. The PIT-tests the extent to which a Pavlovian cue (i.e., a reward-associated cue) can elicit instrumental responses independently paired with the same (specific PIT), or a similar (general PIT), reward (Garofalo and di Pellegrino, 2016). During PIT-test, instrumental responses—previously associated with a reward—are performed under extinction, while task-irrelevant Pavlovian cues are concurrently presented. The crucial question is: can an external stimulus that recalls a reward, modulate reward-seeking behavior? Such a mechanism has both adaptive (e.g., effectively providing for needed food), and maladaptive implications (e.g., looking for food even when not necessary; see Everitt et al., 2001). | |
