The spatial scale of perceptual memory in ambiguous figure perception.
Ambiguous visual stimuli highlight the constructive nature of vision: perception alternates between two plausible interpretations of unchanging input. However, when a previously viewed ambiguous stimulus reappears, its earlier perception almost entirely determines the new interpretation; memory disambiguates the input. Here, we investigate the spatial properties of this perceptual memory, takin...
متن کاملExpectation and satiation accounts of ambiguous figure-ground perception
An expectancy account of figure-ground shifts, promoted as an alternative to satiation theory, was tested. One-hundred and three subjects in six conditions (Experiment 1) were either informed or uninformed about 12 to 13 ambiguous figures, and had either unlimited time or 30 sec in which to respond. In two of the conditions, head and eye movements were restricted, and in one condition, incident...
متن کاملCoherent EEG indicators of cognitive binding during ambiguous figure tasks.
We tested the hypothesis that perception of an alternative image in ambiguous figures would be manifest as high-frequency (gamma) components that become synchronized over multiple scalp sites as a "cognitive binding" process occurs. For 171 combinations of data from 19 electrodes, obtained from 17 subjects and 10 replicate stimuli, we calculated the difference in correlation between the respons...
متن کاملThe Necker cube—an ambiguous figure disambiguated in early visual processing
How can our percept spontaneously change while the observed object stays unchanged? This happens with ambiguous figures, like the Necker cube. Explanations favor either bottom-up factors in early visual processing, or top-down factors near awareness. The EEG has a high temporal resolution, so event related potentials (ERPs) may help to throw light on these alternative explanations. However, the...
متن کاملVoluntary versus Involuntary Perceptual Switching: Mechanistic Differences in Viewing an Ambiguous Figure
Here we demonstrate the mechanistic differences between voluntary and involuntary switching of the perception of an ambiguous figure. In our experiment, participants viewed a 3D ambiguous figure, the Necker cube, and were asked to maintain one of two possible interpretations across four different conditions of varying cognitive load. These conditions differed in the instruction to freely view, ...
