The impact of clinical depression on working memory.
Gary Christopher,John MacDonald +1 more
TL;DR: It is found that depression affects the allocation of attention and all elements of working memory and is proposed that the source of general disruption in both depressed and anxious patients may be a competition between attempts to direct attentional resources to the task in hand and away from the distractive and intrusive effects of automatic negative thoughts.
Journal ArticleDOI
Effects of repeated doses of caffeine on mood and performance of alert and fatigued volunteers
TL;DR: The results showed that caffeine led to a more positive mood and improved performance on a number of tasks, evidence against the argument that behavioural changes due to caffeine are merely the reversal of negative effects of a long period of caffeine abstinence.
Journal ArticleDOI
Looking age-appropriate while growing old gracefully: A qualitative study of ageing and body image among older adults
TL;DR: Thematic analysis highlighted four themes: appearance indicates capability and identity; physical ability trumps appearance; felt pressures to age ‘gracefully’ while resisting appearance changes; and gender and cultural differences.
Journal ArticleDOI

TL;DR: Using participants who had consumed their normal daily quota of caffeine this study alleviated this potential confound as all participants were not withdrawn at the time of testing.
Journal ArticleDOI
Effects of caffeine in overnight-withdrawn consumers and non-consumers
TL;DR: Caffeine generally improved mood and cognitive performance, relative to placebo, in both subjects groups, and the withdrawal hypothesis is not an adequate explanation for the effects of caffeine.
