The Effect of Dispositional Optimism in HRQOL in Patients with Chronic Musculoskeletal Pain Conditions in Greece

The purpose of this investigation was to study the influence of optimism in the quality of life of patients with musculoskeletal problems that were referred to Amfilohia Rehabilitation Center, because of chronic pain and kinetic difficulties. The sample consisted of 96 patients. The questionnaires that were used are the short form health questionnaire (12 questions; SF12), the life orientation test-revised (LOT-R) and a VAS scale for pain measurement. According to the regression analysis performed, dispositional optimism is an independent factor affecting both the physical (β = .249, p < .005) and mental composite score (β = .414, p < .0001) in patients with musculoskeletal problems, even after controlling for the effect of pain intensity.     

Scrutinization, Spatial Attention, and the Spatial Programming of Saccadic Eye Movements

Results are presented from an experiment in which subjects' eye movements were recorded while they carried out two visual tasks with similar material. One task was chosen to require close visual scrutiny; the second was less visually demanding. The oculomotor behaviour in the two tasks differed in three ways. (1) When scrutinizing, there was a reduction in the area of visual space over which stimulation influences saccadic eye movements. (2) When moving their eyes to targets requiring scrutiny, subjects were more likely to make a corrective saccade. (3) The duration of fixations on targets requiring scrutiny was increased. The results are discussed in relation to current theories of visual attention and the control of saccadic eye movements.
