This explanation is consistent with recent studies which support the involvement of the medial temporal lobe in both episodic and semantic memory.58 Alternatively, since PD patients

exhibit impaired duration productions, we can deduct from this that “reference memory” corresponds to procedural memory, which is generally altered in these patients.45 Thus, the representation of time would result in the past experience of time judgment in daily life. We would know what a second signifies, just as we know how to cook. The procedural selleck kinase inhibitor memory necessary for the production task would thus depend on subcortical structures. Attention and executive functions also seem to play an important role Inhibitors,research,lifescience,medical in duration reproduction and production tasks. Further neuropsychological studies, combining Inhibitors,research,lifescience,medical neurological and psychiatric disorders, using the same time estimation tasks for the same duration range, will contribute to a better understanding of the complex interactions between cognition and time estimation.
Autism spectrum disorders (ASDs) are characterized by pervasive deficits in social interaction and communicative behavior, along with restricted and repetitive behavior

patterns,1 that impact multiple domains of functioning throughout the lifespan.2 Deficits in complex3,4 social-communicative (or social functioning) outcomes Inhibitors,research,lifescience,medical are often considered ”core,“ and are the primary target of cognitive and psychosocial interventions.5,6 Considerable research, much of it conducted over the last 10 years, has begun to identify evidence-based interventions for ASD.7 However, as the body of literature Inhibitors,research,lifescience,medical on such interventions evolves, the operative question

begins to move beyond “what works,” towards the more nuanced questions of “why and how does it work, for whom, under what conditions,” 8,10 as well as “when” (ie, at what stage of cognitive and psychosocial development). Treatment research related to ASD has barely begun to explore the common and unique processes by which these interventions “work,” the conditions under which they “work best,” and for whom each type of treatment might be optimal. 4-Aminobutyrate aminotransferase Such research is crucial towards Inhibitors,research,lifescience,medical moving the field beyond the initial treatment package efficacy trials11 characteristic of the early stages of treatment research, and towards a more mature phase in which cognitive and psychosocial interventions may be customized and optimized. In this paper, we first review the most prominent types of psychosocial interventions for “core” social-communicative deficits in ASD. Then, we identify an array of promising and emerging theoretically and empirically derived mechanisms that may underlie these interventions—that is, the “why and how” of them.12 (Throughout this manuscript, the reference to “mechanism” is primarily associated with mechanisms of change [ie, active treatment ingredients or therapeutic processes], as it is used in the intervention research literature.
