Orientations for the successful categorization of facial expressions and their link with facial features.
Horizontal information was recently suggested to be crucial for face identification. In the present paper, we expand on this finding and investigate the role of orientations for all the basic facial expressions and neutrality. To this end, we developed orientation bubbles to quantify utilization of the orientation spectrum by the visual system in a facial expression categorization task. We firs...
متن کاملStimulus type, level of categorization, and spatial-frequencies utilization: implications for perceptual categorization hierarchies.
The type of visual information needed for categorizing faces and nonface objects was investigated by manipulating spatial frequency scales available in the image during a category verification task addressing basic and subordinate levels. Spatial filtering had opposite effects on faces and airplanes that were modulated by categorization level. The absence of low frequencies impaired the categor...
متن کاملDiscrimination thresholds for smiles in genuine versus blended facial expressions
Genuine smiles convey enjoyment or positive affect, whereas fake smiles conceal or leak negative feelings or motives (e.g. arrogance, contempt, embarrassment), or merely show affiliation or politeness. We investigated the minimum display time (i.e. threshold; ranging from 50 to 1,000 ms) that is necessary to distinguish a fake from a genuine smile. Variants of fake smiles were created by varyin...
متن کاملA Label Superiority Effect in Children’s Categorization of Facial Expressions
In three studies (N’s = 360, 68, 160), children (2 to 7 years of age) were asked to categorize various facial expressions. The emotion category was specified to the child by its label (such as happy), its facial expression (such as a smile), or both. From the youngest to the oldest children and for all 3 emotion categories examined (happiness, anger, and sadness), results showed a Label Superio...
متن کاملImproved categorization of subtle facial expressions modulates Late Positive Potential.
Biases in facial expression recognition can be reduced successfully using feedback-based training tasks. Here we investigate with event-related potentials (ERPs) at which stages of stimulus processing emotion-related modulations are influenced by training. Categorization of subtle facial expressions (morphed from neutral to happy, sad or surprise) was trained with correct-response feedback on e...
