what are impossible fiugures?
a shape or form in which different components produce conflicting and mutually exclusive interpretations.
how does it work?
a person looks at a two-dimensional picture.The vision center of the brain does much of its work subconsciously and automatically.It interprets the figure as a three-dimensional object
research Question
Do 4-month-old infants use certain types of pictorial depth information to differentiate between images of three-dimensionally possible and impossible objects?
methodology
30 participants across 3 experiments. participants were seated in a chair approximately 90 cm from the wire frame. An experimenter rotated the frame to present the central vertex as both convex and concave while the participant observed binocularly. Following a within-subjects design, participants completed 2 conditions with 6 trials per condition. Half of the participants received the monocular condition first, as a block of trials, and the other half received the binocular condition first. In each trial, participants were asked “does the middle point appear to be pointing out towards you or back away from you?” Between trials, participants were asked to look away from the display for a minimum of 2 s before continuing on to the next trial.
dependent variables
Looking time, measured in seconds
conclusions
4-month-olds use pictorial depth information to recognise impossible objects
