The Quarterly Journal of Experimental Psychology is a leading international journal that publishes original articles on any topic within the field of experimental psychology. Papers of the highest standard are accepted over a wide variety of topics. The majority of papers published are substantial experimental reports. However, authoritative Review Articles and theoretical treatments are welcome, as are brief experimental reports that will be published rapidly in their own category of Short Articles. The journal covers the areas of learning, memory, motivation and cognitive processes in both non-human and human animals. This includes studies examining the acquisition and use of knowledge about the world, the nature of such knowledge, and the relationship between knowledge and behaviour. Studies are welcome that examine associative and causal learning, attention, memory, reasoning, problem solving, decision-making, mental imagery, action and motor control, perception, language and related topics. Manuscripts that examine the neural mechanisms underlying any of these psychological processes, and those that include the use of functional brain imaging techniques (e.g., fMRI, PET, EEG) are also invited. Similarly encouraged are theoretically driven experimental reports on the effects of healthy ageing, neurological damage or mental disorders within the major topic areas above, as are papers that report computational modelling of behavioural data. The journal encourages and accepts papers from all over the world, with articles from the UK, continental Europe, North America, and elsewhere in the world. The journal is read internationally, and its contributors and editorial board are similarly international.
