Grouping by closure influences subjective regularity and implicit preference
Journal Title: i-Perception - Year , Vol 3, Issue 8
Abstract
A reflection between a pair of contours is more rapidly detected than a translation, but this effect is stronger when the contours are closed to form a single object compared to when they are closed to form 2 objects with a gap between them. That is, grouping changes the relative salience of different regularities. We tested whether this manipulation would also change preference for reflection or translation. We measured preference for these patterns using the Implicit Association Test (IAT). On some trials, participants saw words that were either positive or negative and had to classify them as quickly as possible. On interleaved trials, they saw reflection or translation patterns and again had to classify them. Participants were faster when 1 button was used for reflection and positive words and another button was used for translation and negative words, compared to when the reverse response mapping was used (translation and positive vs. reflection and negative). This reaction time difference indicates an implicit preference for reflection over translation. However, the size of the implicit preference was significantly reduced in the Two-objects condition. We concluded that factors that affect perceptual sensitivity also systematically affect implicit preference formation.

Hearing mouth shapes: Sound symbolism and the reverse McGurk effect
In their recent article, Sweeny, Guzman-Martinez, Ortega, Grabowecky, and Suzuki (2012) demonstrate that heard speech sounds modulate the perceived shape of briefly presented visual stimuli. Ovals, whose aspect ratio (re...

The utility of defocus blur in binocular depth perception
The question of whether defocus blur is a quantitative cue for depth perception is a topic of renewed interest. A recent study suggests that relative defocus blur can be used in computing depth throughout the visual fiel...
View-based matching can be more than image matching: The importance of considering an animal's perspective
Using vision for navigation is important for many animals and a common debate is the extent to which spatial performance can be explained by “simple” view-based matching strategies. We discuss, in the con...
