Abstract
Objectives
This research aimed to systematically review the acute effects of amphetamine (AMP), a dopamine-releasing agent, on working memory (WM) and other cognitive performances. The investigation also aimed to review the impact of personality traits on the subjective and objective effects of AMP and possible links between personality traits and effects of AMP.
Methods
Previous double-blind controlled studies assessing the main effects of AMP on WM and other cognitive performances in healthy volunteers were systematically reviewed. An electronic search was performed in the PUBMED and SCOPUS databases. Narrative reviews of the influence of personality traits on the subjective and objective effects of AMP were included.
Results
Nineteen WM studies were included in the current review. Seven studies found effects of AMP on spatial WM, but only one study found the effect of AMP on verbal WM. Thirty-seven independent studies on other aspects of cognitive performance were identified. Twenty-two reported effects of AMP on cognitive functions. Studies also showed that personality traits are associated with the subjective effects of AMP. However, few studies reported the impacts of personality traits on the objective (such as WM) effects of AMP.
Conclusion
Overall, findings indicate that AMP has mixed-effects on spatial WM and other cognitive functions, but it lacks effects on verbal WM. Although there are insufficient studies on objective measures, studies also indicated that the subjective effects of AMP administration are linked to between-person variations in personality traits.
期刊介绍:
Human Psychopharmacology: Clinical and Experimental provides a forum for the evaluation of clinical and experimental research on both new and established psychotropic medicines. Experimental studies of other centrally active drugs, including herbal products, in clinical, social and psychological contexts, as well as clinical/scientific papers on drugs of abuse and drug dependency will also be considered. While the primary purpose of the Journal is to publish the results of clinical research, the results of animal studies relevant to human psychopharmacology are welcome. The following topics are of special interest to the editors and readers of the Journal:
-All aspects of clinical psychopharmacology-
Efficacy and safety studies of novel and standard psychotropic drugs-
Studies of the adverse effects of psychotropic drugs-
Effects of psychotropic drugs on normal physiological processes-
Geriatric and paediatric psychopharmacology-
Ethical and psychosocial aspects of drug use and misuse-
Psychopharmacological aspects of sleep and chronobiology-
Neuroimaging and psychoactive drugs-
Phytopharmacology and psychoactive substances-
Drug treatment of neurological disorders-
Mechanisms of action of psychotropic drugs-
Ethnopsychopharmacology-
Pharmacogenetic aspects of mental illness and drug response-
Psychometrics: psychopharmacological methods and experimental design
