A autokinetic illusion autokinetic effect is a phenomenon of human visual perception in which a stationary, small point of light in an otherwise dark or featureless environment appears to move. It was first recorded by a Russian officer keeping watch who observed illusory movement of a star near the horizon.
Attempts to show that in studies of the autokinetic illusion, if the interdependence of theories and measurement methods is first considered, a systematic account becomes possible.
Muzafer Sherif was born in 1906 in Izmir, Turkey. He earned a bachelor's degree and a master's degree in his native country but then went on to earn his Ph.D. at Columbia University in America.
Imaging the visual autokinetic illusion with fMRI. ... This autokinetic illusion increases with increasing fixation time. Eleven healthy subjects were examined by fMRI while fixating an LED in darkness for 35 s. BOLD signal changes of the first and the second half of the fixation period were compared. ...

This study was designed to test the following hypotheses: (a) reports of autokinetic movement increase with increasing exposure time; (b) reports of movement in the vertical plane occur with greater frequency than reports of movement in the horizontal plane. Forty Ss, who were told that they were radar watchkeepers, observed a pin point of light in a dark room for 30 min. and indicated the ...
Sex of the experimenter as a variable in the autokinetic illusion JOHN L. ALLEN, SUSAN J. SIPES, and GREGORY P. SIPES Sp",;ng Arbor College, Spring Arbor, Michigan 49283 Twenty·two female undergraduate students were tested for agreement with an experimenter's suggested direction of movement in an autokinetic illusion experiment.
The autokinetic effect occurs when a stationary point of light in an otherwise darkened room is perceived as moving. This effect can be enhanced or guided through the power of suggestion (e.g., people can be primed to see the light move and trace out certain words). One goal of this study was to
The present study examines the relationships between perceptual-deprivation tolerance and three variables: extraversion, the autokinetic (AK) phenomenon and field-dependence. In addition, the relationship between extraversion and autokinesis (AK) was investigated. ... Regarding the AK phenomenon, this is a perceptual illusion in which a single ...
Why would Muzafer Sherif, a social psychologist, choose the autokinetic effect (a perceptual illusion) to study social conformity? A) He wanted participants to feel pressure to obey his instructions. B) He wanted to construct a situation that was ambiguous. C) He wanted to use a dark room to foster a sense of cohesion in the group.
Sometimes called the autokinetic effect, autokinesis is a visual illusion where a light can appear to move when stared at in the dark. It occurs most often on dark nights in areas with few visual cues (such as other lights or other illuminated obj...
A recent paper by Alexander, Zucker and Brody (1970) reported findings contrary to Sherif's (1935) original results and the results of many subsequent replications.
One of the first researchers to study social influence in ambiguous situations. He looked at the autokinetic phenomenon, an illusion in which a stationary pinpoint of light in a totally dark room appears to move. Three people were individually put in a dark room and asked to estimate how many inches the stationary light appeared to move.
The present study tested the effects of awakening from the two phases of sleep on two additional visual illusions, the Necker cube and autokinetic illusions. 12 young adults were wakened from REM and NONREM sleep and tested on both illusions for three 1-min. trials, within 1 to 2 min. of the awakening.

Occurrences Edit. Illusory motion can occur in different circumstances. Stroboscopic images - Where a series of static images are viewed in sequence at a high enough rate that the static images appear blend into a continuous motion. An example is a motion picture. Optical art (Op art.) - Where artists use simple black and white patterns that create vivid illusions of motion, known as optical flow.
9/10/2013 · A study conducted by Eva Riedel, et al, published in 2005, "Imaging the visual autokinetic illusion with fMRI" "During fixation of a stationary, dim light-emitting diode (LED) in complete darkness, a subtle, apparent motion is perceived which is called autokinesis. This autokinetic illusion increases with increasing fixation time.
3/11/2019 · The Muller-Lyer illusion is a well-known optical illusion in which two lines of the same length appear to be of different lengths. The illusion was first created by a German psychologist named Franz Carl Muller-Lyer in 1889.
