A depressive state can manifest in different ways, including lack of sleep or appetite, loss of energy, and even a loss of interest in doing things. It is also manifested by problems of concentration, feelings of guilt, excessive feelings of failure and even, sometimes, by suicidal ideation (Provencher, Soucy Chartier, & Mirabel-Sarron, 2015). If this state contains concentration problems, it may affect the processing of temporal information given the prominent role of attention in temporal tasks (see Chapter 9). Moreover, a typical symptom in people with depression is related to the experience of time that seems to flow much more slowly.
