Biological Psychology publishes original scientific papers on the biological aspects of psychological states and processes. Biological aspects include electrophysiology and biochemical assessments during psychological experiments as well as biologically induced changes in psychological function. Psychological investigations based on biological theories are also of interest. All aspects of psychological functioning, to include psychopathology, are germane. The Journal concentrates on work with human subjects, but welcomes work with animal subjects conceptually related to issues in human biological psychology. Empirical reports are the core of the Journal but review articles as well as technical notes relevant to biological psychology are encouraged. A brief report section will publish well written papers of less than 900 words with minimal delays from the submission date. Book reports and critical commentary of relevance to our readership are also published. Finally, announcements are provided particularly of national and international meetings of interest to our readership.
