(1) Subjects were interviewed using the Tennessee Self-Concept Scale (Fitts, 1965), the Personal Stress Inventory, and a causal explanations questionnaire.
(2) The general conclusion drawn from the two experiments was that motor capacity, as assessed by Fitts' tapping task, is not an extremely useful measure.
(3) For experimental data generated from five Ss, (a) the distribution tended to be unimodal and more peaked than a normal distribution, (b) the skewness of the distribution was predominantly positive and (c) the standard deviation, in addition to the mean, of movement time was significantly affected by the complexity of the task as measured by Fitts' index of difficulty, while the skewness and the kurtosis were not.
(4) When interaction among variables exists, the dual-task paradigm can not simply be modeled as a Sternberg memory task plus a Fitts target acquisition, rather, new performance metrics for the memory search and target acquisition tasks require that all the significant variables in the MWPE protocol be modeled.
(5) In this article, the relative fittnesses of heterozygotes (with both electromorphs active) and homozygotes (with activity demonstrable for only one or the other electromorph) for the Zw locus are described.
(6) Eighty-eight undergraduate students completed the Jenkins Activity Survey, which measures the Type A personality; the Tennessee Self-Concept Scale (TSCS; Fitts, 1965); the Marlowe-Crowne Social Desirability Scale; the A-Trait Scale (Spielberger, Gorsuch, & Lushene, 1970), and the Eysenck Personality Inventory.
(7) Serial tapping by 5-, 7- and 9-yr.-old boys and girls, as measured by Fitts' Law, was recorded.
(8) All Ss were given Fitt's test of attitude towards school.
(9) On a modification of the Fitts Reciprocal Tapping task children moved a stylus (held in the hand or attached to a special shoe worn on the foot) between two metal targets separated by different distances.
(10) However, evidence of severe nonlinearities in the measured humam movement responses did not support the use of linear control models in explaining the empirical validity of Fitts' law in predicting human motor performance.
(11) The classic finding for relatively long movements is that movement time, measured from leaving the initial position until contact with the target, depends on both distance and target size according to a relationship known as "Fitts' law."
(12) Subjects performed a spatially constrained stylus-to-hole Fitts reciprocal movement task designed to simulate high-incentive manual assembly operations while providing basic information regarding changes in human move and positioning capabilities.
(13) These included the Fitts law psychomotor task, the Stroop colour-word test, the Sternberg short term memory scanning test, the short term memory span test, and the continuous recognition memory test.
(14) Movements performed with closed eyes were characterized with higher peak speeds and unchanged variability in seeming violation of the Fitt's law and in a good correspondence to the model.
(15) In the Fitts paradigm the subject moves a stylus to the left or right of an initial rest position to reach targets that vary in size and in distance from the initial position.
(16) Self-concept was measured by Fitts' Tennessee Self-concept Scale and scored using both Clinical and Counselling forms.
(17) The effects of task complexity on movement ipsilateral to lesion were examined using the Fitts tapping task [Fitts, P.M., J. exp.
(18) Ireland's foreign minister and deputy premier Eamon Gilmore tonight congratulated McDonnell on becoming leader of the party founded by John Hume and Gerry Fitt.
(19) The violation of Fitts' Law was confined to the easy target hand.
(20) Results supported Fitts' original theory that various limb segments may show different maximum information processing rates.
