Our manipulation of speed-accuracy instructions was expected to primarily affect the detection of motion coherence rather than the discrimination of motion direction (i.e., left vs. right).
Because of the manipulation of the speed, the durations of one stimulus sequence for the 2×, 1.5×, 0.5×, and 0.25× groups were 30, 40 s, 2, and 4 min, respectively.
Already, his manipulation of time, speeding it up and slowing it down according to the needs of his story, and his scanting of the routine and banality that make up most of life's substance take unrealistic liberties.
The present findings are consistent with the results of earlier studies with humans, although it remains to be determined why the manipulation of biological motion speed had differential effects on the performance, depending on whether the speed was increased or decreased.
It is noteworthy that the manipulation of the rotational speed of a DC motor is used only to exemplify a physically covert interference in an NCS.
The recorded version is approximately in B-flat major; owing to manipulation of the recording speed, the finished version is not in standard pitch (some, for instance consider that the tonic is A).
The findings from the LNS task were the strongest, suggesting that the processing load for individuals with either ADHD subtype may be more taxing when multiple executive functions are required such as in LNS which demands sequencing, manipulation of information, processing speed, auditory memory and perhaps visual-spatial imagery [ 51].
Microbial communities could be ideal for the general study of SADs as well, as the degree of manipulation possible, speed and cost associated with a census of bacteria are far more amenable to testing a large number of hypotheses than with communities of plants or animals.
Moreover, work by Kühnen and Oyserman [49], found that manipulation of self-focus improved speed and accuracy on tasks that were congruent with the primed self focus.
Experiment 4 demonstrated that shoaling behaviour was substantially influenced by speed manipulation of biological motion.
