The ability of the saccadic system to change motor plans in scanning letter strings.

Comparison of Effectiveness of Motor-Working Memory Training and Perceptual-Motor Exercises on Digit Span and Letter–Number Sequencing in Educable Children with Intellectual Disabilities

Background and Objective: Appropriate programs should be provided to improve the function of memory, learning, and the effects of processing efficiency in the daily life of children with intellectual disabilities. Therefore, the present study aimed to compare the effectiveness of motor-working memory training and perceptual-motor exercises on digit span and letter-number sequencing in educable ...

Influence of foveal distractors on saccadic eye movements: A dead zone for the global effect

Three experiments investigated the global effect with foveal distractors displayed in the same hemifield as more eccentric saccade targets. Distractors were x-letter strings of variable length and targets corresponded to the central letter of letter strings (e.g., 'xxxkxxx'). Results showed that only foveal distractors longer than four letters (about 1 degree) deviated the eyes in a center-of-g...

The planning of refixation saccades in reading

The planning of the refixation saccade, i.e. the second saccade on 9- and 11-letter-strings, was assessed in two reading experiments that examined the influence of a length change at different times during the first fixation on a letter string. The results showed that the saccadic system was able to modify the first motor program if the new length information was available 150-190 ms before the...

Nonlinear vibration analysis of axially moving strings in thermal environment

In this study, nonlinear vibration of axially moving strings in thermal environment is investigated. The vibration haracteristics of the system such as natural frequencies, time domain response and stability states are studied at different temperatures. The velocity of the axial movement is assumed to be constant with minor harmonic variations. It is presumed that the system and the environment...
