This evidence suggests that both caffeine and coffee flavour exert a similar beneficial effect on the early stages of information processing, that is leads to greater perceptional sensitivity.
People get in a better mood and have pleasure from coffee to relax and to cope with stress.
These effects are supported by observations and questionnaire data, indicating that effects of coffee may depend in particular on psychological factors such as expectancies on the effects of caffeine and its beverage coffee, situational factors and the pleasure people have when they drink coffee. For these reasons it is argued to do more ecologically valid research on the effects of coffee as it is enjoyed in daily life by the regular consumer. Some suggestions are given as for the design of such studies. Managed by Traffic Interactive . All rights reserved.
