Factors underlying visual illusions are illusion-specific but not feature-specific.
TLDR
It is suggested that most illusions make up their own factor, as in perceptual learning, which suggests that there is no unique common mechanism for the tested illusions.
Individual differences in the Müller-Lyer and Ponzo illusions are stable across different contexts
TLDR
Although strong intra-illusion correlations are found for both Müller-Lyer and Ponzo illusions, a mixed-effects model analysis did not reveal any significant interaction between context and age, and found only weak inter- Illusion correlations, suggesting that the structure underlying these two spatial illusions includes several specific factors.
Motor response specificity in perceptual learning and its release by double training.
TLDR
It is shown that perceptual learning with mouse adjustments transfers to the untrained hand, but only for the trained adjustment condition, and that a double training procedure enables transfer from the mouse adjustment to the button press condition.
Sex-related differences in vision are heterogeneous
TLDR
A practical consequence of the results is that it is important to control for sex in vision research, and that findings of sex differences for cognitive measures using visually based tasks should confirm that their results cannot be explained by baseline sex differences in visual perception.
Linking perceptual learning with identical stimuli to imagery perceptual learning.
TLDR
It is shown that perceptual learning with identical stimuli occurs in the visual domain, too, and two paradigms were linked by telling observers that only the very same bisection stimulus was presented in all trials and asked them to imagine the central line to be offset either to the left or right.
Is the perception of illusions abnormal in schizophrenia?
Stimulus blanking reveals transsaccadic feature transfer
TLDR
It is found that shortly blanking a contrast-defined object during and after saccades allows to recover a detailed representation of its orientation, allowing participants to perform better on the trans-saccadic orientation task.
