Coupling between reaching movement direction and hand orientation for grasping.
In a previous work, we demonstrated that orientation of the hand in the horizontal plane (azimuth) at the time of grasping depends on the direction of the reaching movement in the horizontal plane. Here we report three experiments to further investigate the generality of this coupling. Azimuth of the hand for grasping was studied while subjects were reaching for objects placed at various locati...
متن کاملFractionated Reaction Times and Movement Times of Down Syndrome and Other Adults With Mental Retardation
A fractionation technique was employed to determine the locus of reaction time delay in Down syndrome (DS) and other adult subjects with mental retardation (MH). Twenty-three subjects (8 nondisabled, 8 MH, and 7 DS) responded to a light, sound, and combination lightlsound signal. Dependent measures of premotor time, motor time, total reaction time, and movement time were obtained during a 20" e...
متن کاملReaction Times and Movement Times: Benefits of Practice to Younger and Older Adults
The purpose of this study was to examine the effect of practice on simple reaction time (RT), movement time (MT), and response consistency for two arm-reaching tasks of graded complexity in younger and older adults. Forty subjects, 20 younger adults (age range = 20-29 years) and 20 older adults (age range = 60-82 years), were randomly subdivided into practice and control groups. All subjects we...

15 صفحه اولAugmented feedback influences upper limb reaching movement times but does not explain violations of Fitts' Law
Fitts' (1954) classic theorem asserts that the movement time (MT) of voluntary reaches is determined by amplitude and width requirements (i.e., index of difficulty: ID). Actions associated with equivalent IDs should elicit equivalent MTs regardless of the amplitude and/ or width requirements. However, contemporary research has reported that amplitude-based contributions to IDs yield larger incr...
