Cognitive flexibilityCognitive flexibility is an intrinsic property of a cognitive system often associated with the mental ability to adjust its activity and content, switch between different task rules and corresponding behavioral responses, maintain multiple concepts simultaneously and shift internal attention between them. The term cognitive flexibility is traditionally used to refer to one of the executive functions. In this sense, it can be seen as neural underpinnings of adaptive and flexible behavior.
Executive dysfunctionIn psychology and neuroscience, executive dysfunction, or executive function deficit, is a disruption to the efficacy of the executive functions, which is a group of cognitive processes that regulate, control, and manage other cognitive processes. Executive dysfunction can refer to both neurocognitive deficits and behavioural symptoms. It is implicated in numerous psychopathologies and mental disorders, as well as short-term and long-term changes in non-clinical executive control.
Syndrome de dysrégulation dopaminergiqueLe syndrome de dysrégulation dopaminergique (SDD) est un ensemble de troubles du comportement touchant des patients parkinsoniens traités par médicaments antiparkinsoniens. Cet ensemble se décompose en troubles du comportement ; punding ; dépendance au médicament. trouble de l'humeur : le patient se retrouve tantôt avec un sentiment de type maniaque (estime de soi, sentiment d’invulnérabilité ...), tantôt avec un tableau dépressif (fatigue, tristesse de l'humeur ...).
Stimulus controlIn behavioral psychology (or applied behavior analysis), stimulus control is a phenomenon in operant conditioning (also called contingency management) that occurs when an organism behaves in one way in the presence of a given stimulus and another way in its absence. A stimulus that modifies behavior in this manner is either a discriminative stimulus (Sd) or stimulus delta (S-delta). Stimulus-based control of behavior occurs when the presence or absence of an Sd or S-delta controls the performance of a particular behavior.
