Emotional Expression by Infants through Vocalization. Perceptual Evaluation.

Individual Differences in Infant Development of Emotional Expression through Vocalization

Developmental aspects of emotional expression through vocalizations by infants were investigated using perceptual experiments by normal hearing adults. The voices used were 517 samples recorded from 6 infants at 6, 9,12 and 17 months of age, The results were as follows. 1) Two-way ANOVA with the factors of individuality and age showed significant effects of infant and infantage interaction on t...

Rapid perceptual integration of facial expression and emotional body language.

In our natural world, a face is usually encountered not as an isolated object but as an integrated part of a whole body. The face and the body both normally contribute in conveying the emotional state of the individual. Here we show that observers judging a facial expression are strongly influenced by emotional body language. Photographs of fearful and angry faces and bodies were used to create...

Emotional memory is perceptual.

In two experiments it was investigated which aspects of memory are influenced by emotion. Using a framework proposed by Roediger (American Psychologist 45 (1990) 1043-1056), two dimensions relevant for memory were distinguished the implicit-explicit distinction, and the perceptual versus conceptual distinction. In week 1, subjects viewed a series of slides accompanied with a spoken story in eit...

Generalized perceptual linear prediction features for animal vocalization analysis.

A new feature extraction model, generalized perceptual linear prediction (gPLP), is developed to calculate a set of perceptually relevant features for digital signal analysis of animal vocalizations. The gPLP model is a generalized adaptation of the perceptual linear prediction model, popular in human speech processing, which incorporates perceptual information such as frequency warping and equ...
