![]() Statistical analyses and modeling of data support the idea according to which these results may be explained by a slowing down of the internal clock in the depressive participants. The sadness scores assessed by the Brief Mood Inventory Scale (BMIS) also suggest that the emotional state of sadness in the depressive participants goes some way to explaining their temporal performance. Holmes, 1999), the graphic experiment generation software PsyScope (Cohen, MacWhinney, Flatt, &. Test instructions were reviewed with the subject by the examiner via the scanner intercom system before the onset of each run. In a previous paper (Roche, Stewart, & Barnes. This article provides important instructions on how to update your software. The data were analyzed using FMRIB Software Library 4.1 (FSL, Analysis Group, FMRIB, Oxford, UK). Responses were made using a fiber-optic response buttons, using the fingers of the right hand. Participants viewed stimuli projected onto a screen through a mirror mounted on the head coil. These results thus indicate that the probe durations were underestimated by the depressive participants. The start of the fMRI scan was triggered automatically from PsyScope software. Here you can find the legacy software update and image links for download. Stimuli were presented using a laptop running PsyScope (Cohen et al., 1993). In contrast, the sensitivity to time was similar in these two groups of participants. The responses were made using the K and D keys on the computer keyboard. Psyscope A collection of psychology software for the Mac platform. Most of it is for the PC environment, but many of the links are to Mac and other platform sites. They were seated in front of a computer that controlled the stimuli and recorded the data using PsyScope software for Macintosh. This is an extensive list of psychology related software and with many links to other sites with software. Furthermore, the higher the depression score was, the shorter the signal duration was judged to be. The participants were tested individually in a quiet room in Blaise Pascal University, Clermont-Ferrand, France. Psiscope website is under construction Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. ![]() The data showed that the bisection function was shifted toward the right, and that the point of subjective equality was higher in the depressive than in the non-depressive participants. The participants performed a temporal bisection task in which they had to categorize a signal duration of between 4 ms as either as short or long. The behavioral tasks were presented using an Apple G4 Macintosh computer (Apple Computer, Cupertino, CA), programmed with PsyScope software (Cohen et al., 1993).Within the scanner, the stimulus display was projected by an Epson PowerLite 703c liquid crystal display projector (Epson America, Long Beach, CA) onto a Plexiglas screen positioned at the end of the bore. This study examined changes in time perception as a function of depressive symptoms, assessed for each participant with the Beck Depression Inventory (BDI).
