      Background. Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that is affecting an alarming number of individuals, with estimates of 1 in 88 children in the United States (Centers for Disease Control and Prevention [CDC], ).Theories regarding the cause of autism are numerous and highly debated, as the disorder affects persons from every racial, ethnic, and Cited by: Initial analysis including all trials indicated no effect of experimental condition on self-nominated driving speeds, χ 2 (2) = , p A limitation of this analysis is that the posted speed limits for the roads depicted in the clips varied from 60 km/h to km/h, meaning there was greater variation within conditions than between Author: Vanessa Beanland, Vanessa Beanland, Rachael A. Wynne. Each trial (total duration: 12 s) started with a fixation cross (duration, 2 s), followed by an instruction screen (1 s), indicating the category of pictures to which the participant needed to respond (furniture, tools, or toys) and the speed of the trial (“>” for a slow trial, “>>>” for a fast trial).

Beggars in Spain is the sort of sf novel that posits a basic idea and extrapolate from that the foundation to look at the ramifications and implications of this idea from all possible angles.

The effects of repeated trials and prolonged fixation on error in the Müller-Lyer figure. by R. H. Day Download PDF EPUB FB2

Two groups of Ss received monocular repeated trials with a large display of the Brentano version of the Muller-Lyer illusion. Intraocular transfer of practice effects of one group was compared to interocular transfer for the other by: 1. An experiment with the Müller-Lyer figure is reported in which variation in instructions resulted in a change in the magnitude of the visual illusion under normal viewing conditions.

Variation in instructions did not, however, have a differential effect on the magnitude of the illusion when Ss inspected the figure by means of a point source of light attached to one by: 2.

Two experiments are reported in which a decrement in the magnitude of the Müller-Lyer illusion was found if free eye movements were allowed.

Little or no decrement was obtained if Ss fixated one point of the figure during inspection. In one experiment eye movements were recorded. Saccades across the perceptually short side of the Muller-Lyer figure were found to be shorter than across the Cited by:   Distinctive fin effects supported the hypothesis that cue distinctiveness contributes to the illusion, but showed also that it depends on modality-specific conditions, and is not the main factor.

book 15 Ss were assigned to 1 of 3 viewing conditions to examine the effects of steady fixation and eye movements on decrement of the Müller-Lyer illusion. In Condition 1, a large number of brief tachistoscopic exposures were given with regular intervals during the inspection period and the Ss were instructed to fixate the center of the by: 1.

Muller-Lyer Illusion (Cultural effects) Only Western cultures are tricked by the arrows into seeing one line as shorter than the other because the rectangularly constructed world makes them perceive corners as turning inward, and as being inside buildings.

The fourth property is no longer true as the various repeated trials are not independent. The result of the first trial has an effect on the possible result of the second trial, etc. Using the tree we can find the probability of various events as in Example Example Of 20 balls in a.

The pattern of these results suggests that theories of Müller-Lyer decrement must incorporate a factor attributable to, or correlated with, inspection time, whose effect in reducing illusion magnitude is confined mainly to the first 1 or 2 min of active visual inspection of the Brentano illusion by: The detrimental effects of a ringing phone on cognitive performance were investigated in four experiments.
