As indicated above, a key goal of the project is to foster development of validated tasks that are feasible for

use in assessing the constructs in clinical trials or in practical clinical use. This process may be expected to proceed gradually over a series of years; tasks for some constructs may be available in the near future, while measures for others may require a longer period of exploratory research and validation. An integrative approach Despite its roots in the study of cognition in schizophrenia, RDoC incorporates a broad view in which cognition is Inhibitors,research,lifescience,medical not considered to be “special” or distinct from other functions, such as affective and social processes, that are served by the brain. Similar to the concerns about the consequences of scientific hyper-focus on categorical Inhibitors,research,lifescience,medical diagnoses, similar unintended consequences have followed the “cognitive revolution,” including reification of conceptual categories (eg, cognitive, affective, social) that have “no discrete Inhibitors,research,lifescience,medical reality in the brain”.9 Cromwell and Panksepp identify the “potentially invidious consequences” of this overuse of cognition (“cognitivism”), such as the tendency for “cognition”

to be “widely used as a moniker for practically all the interesting functions the brain performs to facilitate behavioral adaptations and survival” Inhibitors,research,lifescience,medical (p 2027). RDoC’s integrative approach XAV-939 datasheet includes cognition

as part of a conceptual framework that incorporates social processes, arousal/regulatory systems, and negative and positive valence systems as the major superordinate domains, because these behavioral systems and the neural circuits that implement them have Inhibitors,research,lifescience,medical all evolved to serve the motivational and adaptive needs of the organism. The scientific basis for drawing brain-based boundaries among these domains is evolving. As the identification of elements in the RDoC matrix proceeds and the patterns of overlap among and specificity within different domains become apparent, the behavioral and neural networks with selective specialization and those with highly integrated activities will become clearer. This has become apparent in the early stages of the RDoC process, as certain neural circuits have been included in the matrix because of their Thymidine kinase specific importance to a single construct and others (eg, circuits involving the amygdala, basal ganglia) because of their involvement across multiple constructs. An example of how an approach consistent with the RDoC matrix may advance research regarding cognitive functioning in psychotic spectrum disorders is provided in a recent paper examining a large Finnish cohort involving probands with a schizophrenia diagnosis and family members.
