This study examined the effect of different types of loss of control on the quality and quantity of the frustration response in 4- to 6-month-old infants. To establish an expectancy, all infants received 4 minutes of contingency training in which infants were presented with slides and music after they performed a pulling response with their right…

Examined 8- to 10-month-olds' responses to standard procedures eliciting joy, fear, anger, and discomfort. Found that response parameters to standard procedures cohered strongly within each episode. Responses cohered across same-emotion episodes, except for anger. Responses and father-reported temperament related to infant's emotional tone in…

To make the point that infant emotions are more dynamic than suggested by Differential Emotions Theory, which maintains that infants show the same prototypical facial expressions for emotions as adults do, this paper explores two questions: (1) when infants experience an emotion, do they always show the corresponding prototypical facial…

Two experiments examined how different frustration contexts affect the instrumental and emotional responses of 4- to 5-month-olds. Both experiments showed that arm responses increased when the contingent stimulus was lost or reduced but decreased when control of the stimulus was lost under noncontingency. Facial expressions of anger, but not…

A cross-national study examined what Japanese, Chinese, and American infants communicated to naive observers in various contexts when facial information was not available. Found that cultural differences were manifested primarily in deviations from expected responses to situations; Chinese and Japanese were not rated as more surprised in the…

It is difficult to make progress in the study of emotions and emotional development if the meanings assigned to central constructs vary widely across investigators. This book clarifies and synthesizes the different ways in which emotion researchers approach fundamental questions about the nature of emotion and emotional development. Theorist and…
