“…According to the selective association account, the consoling ID speech segment might be selectively associated with the sad (or nonsmiling) face, but so might the arousing ID speech be selectively associated with the smiling face. Furthermore, if infants can extract adult-appropriate affect from emotionally charged AD speech, a point for which there is currently insufficient data to permit a strong conclusion (see Aldridge, 1994), selective associations should have occurred in the sad AD conditions.…”

“…The current sad AD speech sample was rated by adults as conveying sad affect to infants and yet was not associated with a sad face by 4-month-olds. It is unclear, however, to what extent young infants can extract adult-appropriate affect from AD speech (see Aldridge, 1994). It may be that the greater attentional salience of the ID speech register highlights affective messages conveyed through ID speech, increasing the probability that infants will extract affective messages.…”

The role of affective correspondence between signal and outcome in associative learning was studied in 2 experiments with 4-month-olds. In Experiment 1, an infant-directed (ID) speech segment, categorized by adults as having consoling acoustic properties for infants, was either paired or unpaired with smiling or sad face reinforcers. In other groups, a sad adult-directed (AD) speech segment signaled the smiling or sad faces. Later, all speech segments were tested for their ability to increase infants' visual interest in a checkerboard. Positive summation was observed only when the consoling ID speech segment had signaled the sad face. In Experiment 2, an arousing ID speech segment signaled the smiling or sad face. Positive summation was evident in both conditions. These results show that infants sometimes selectively associate speech segments and faces. Discussion centers on the basis for the selective association.

“…That aside, in a few experiments, researchers have looked at infants’ preferences for vocal expressions. For example, Aldridge (1994) tested neonates using an operant-choice sucking procedure and found that they preferred to listen to happy compared with angry and sad voices. That neonates “worked harder” for the happy voice and “avoided” listening to the sad and angry expressions signifies a preference based on emotional content.…”

The literature on infants' perception of facial and vocal expressions, combined with data from studies on infant-directed speech, mother-infant interaction, and social referencing, supports the view that infants come to recognize the affective expressions of others through a perceptual differentiation process. Recognition of affective expressions changes from a reliance on multimodally presented information to the recognition of vocal expressions and then of facial expressions alone. Face or voice properties become differentiated and discriminated from the whole, standing for the entire emotional expression. Initially, infants detect information that potentially carries the meaning of emotional expressions; only later do infants discriminate and then recognize those expressions. The author reviews data supporting this view and draws parallels between the perceptions of affective expressions and of speech.
