Humans have a remarkable ability to perceive, identify, recognize and interpret biological movements. Point-light diplays (PLD) is the only method used to represent trajectories of human movements in visual material. Biological movement recognition might be disturbed in some disorders.
The aim of the study was to examine if people with central nervous system (CNS) tumors bear deficits in recognizing biological movement. In addition, authors of this study decided to examine whether these deficits are associated with cognitive functions (especially executive functions).
The study was performed at Neurosurgical Department of the Institute of Psychiatry and Neurology in Warsaw, Poland. The patients who were admitted to Neurosurgical Department in the purpose of brain tumour removal were recruited to the study group. The control group consisted of healthy people. Neuropsychological tools (ACE-III, Rey figure, CTT, Ruff Figural Fluidity Test, WAIS-R Digit Span) and a program for biological motions recognition.
In terms of age, education level and gender no statistical differences were observed between the control group and the research group. Our study revealed statistically significant differences in the recognition of biological movement in the control and study group. The correlation analysis between EF and biological movement recognition were found in the following domain of neurophysiological tests: RFFT unique combinations, M-ACE, ACE-III visual-spatial functions, CTT interference indicator.
People affected by brain tumours have impaired ability to recognize biological movements.
