The future is here: A review of foresight systems in anxiety and depression

Abstract

Cognitive models of anxiety and depression have long suggested a central role for future-oriented thinking in these disorders. Experimental studies suggest that anxiety and depression are characterised by distinct future-oriented thinking profiles, and that these profiles are markedly different from those of asymptomatic adults. In this paper, we review these profiles and propose two explanatory models marked by two different neurocognitive systems. The Reconstructive Memory Model emphasises a role for emotionally driven learning and retrieval in episodic foresight (i.e., the construction of future-oriented scenarios), and the Valuation Model proposes that an overweighing of risk and uncertainty estimates can be invoked to explain the future-oriented thought patterns. We consider the effectiveness of interventions aimed at altering such thought patterns. We suggest that future research aimed at elucidating the neurobiological underpinnings of future-oriented thinking in anxiety and depression can play an important role in advancing development of effective biological and psychosocial interventions for these disorders.
