Bernardo; Oliveira, José; Lemos, Raquel; Da Silva Rodrigues, Daniel; da Silva, Joaquim AlvesBackground/Objective: Screening for depression in patients with cancer can be difficult due to overlap between symptoms of depression and cancer. We assessed validity of the Beck Depression Inventory (BDI-II) in this population. Method: Data was obtained in an outpatient neuropsychiatry unit treating patients with and without cancer. Psychometric properties of the BDI-II Portuguese version were assessed separat...
Explicit knowledge of task structure is a primary determinant of human model-ba...
Castro-Rodrigues, Pedro; Akam, Thomas; Snorasson, Ivar; Camacho, Marta; Paixão, Vitor; Maia, Ana; Barahona-Corrêa, J. Bernardo; Dayan, PeterExplicit information obtained through instruction profoundly shapes human choice behaviour. However, this has been studied in computationally simple tasks, and it is unknown how model-based and model-free systems, respectively generating goal-directed and habitual actions, are affected by the absence or presence of instructions. We assessed behaviour in a variant of a computationally more complex decision-makin...
