There is disagreement in the literature about the exact nature of the phenomenon of empathy. There are emotional, cogni- tive, and conditioning views, applying in varying degrees across species. An adequate description of the ultimate and proximate mecha- nism can integrate these views. Proximately, the perception of an object's state activates the subject's corresponding representations, which in turn activate somatic and autonomic responses. This mechanism supports basic behaviors (e.g., alarm, social facilitation, vicar- iousness of emotions, mother-infant responsiveness, and the modeling of competitors and predators) that are crucial for the reproduc- tive success of animals living in groups. The Perception-Action Model (PAM), together with an understanding of how representations change with experience, can explain the major empirical effects in the literature (similarity, familiarity, past experience, explicit teach- ing, and salience). It can also predict a variety of empathy disorders. The interaction between the PAM and prefrontal functioning can also explain different levels of empathy across species and age groups. This view can advance our evolutionary understanding of empa- thy beyond inclusive fitness and reciprocal altruism and can explain different levels of empathy across individuals, species, stages of de- velopment, and situations.

Empathy: Its ultimate and proximate bases.

This article reviews the various literatures on the adjustment of children of depressed parents, difficulties in parenting and parent-child interaction in these families, and contextual factors that may play a role in child adjustment and parent depression. First, issues arising from the recurrent, episodic, heterogeneous nature of depression are discussed. Second, studies on the adjustment of children with a depressed parent are summarized. Early studies that used depressed parents as controls for schizophrenic parents found equivalent risk for child disturbance. Subsequent studies using better-defined samples of depressed parents found that these children were at risk for a full range of adjustment problems and at specific risk for clinical depression. Third, the parenting difficulties of depressed parents are described and explanatory models of child adjustment problems are outlined. Contextual factors, particularly marital distress, remain viable alternative explanations for both child and parenting problems. Fourth, important gaps in the literature are identified, and a consistent, if unintentional, "mother-bashing" quality in the existing literature is noted. Given the limitations in knowledge, large-scale, long-term, longitudinal studies would be premature at this time.

Children of depressed parents: an integrative review.

Empathy accounts for the naturally occurring subjective experience of similarity between the feelings expressed by self and others without loosing sight of whose feelings belong to whom. Empathy involves not only the affective experience of the other person’s actual or inferred emotional state but also some minimal recognition and understanding of another’s emotional state. In light of multiple levels of analysis ranging from developmental psychology, social psychology, cognitive neuroscience, and clinical neuropsychology, this article proposes a model of empathy that involves parallel and distributed processing in a number of dissociable computational mechanisms. Shared neural representations, self-awareness, mental flexibility, and emotion regulation constitute the basic macrocomponents of empathy, which are underpinned by specific neural systems. This functional model may be used to make specific predictions about the various empathy deficits that can be encountered in different forms of social and neu...

Maternal depression and parenting behavior: a meta-analytic review

A large body of literature documents the adverse effects of maternal depression on the functioning and development of offspring. Although investigators have identified factors associated with risk for abnormal development and psychopathology in the children, little attention has been paid to the mechanisms explaining the transmission of risk from the mothers to the children. Moreover, no existing model both guides understanding of the various processes' interrelatedness and considers the role of development in explicating the manifestation of risk in the children. This article proposes a developmentally sensitive, integrative model for understanding children's risk in relation to maternal depression. Four mechanisms through which risk might be transmitted are evaluated: (a) heritability of depression; (b) innate dysfunctional neuroregulatory mechanisms; (c) exposure to negative maternal cognitions, behaviors, and affect; and (d) the stressful context of the children's lives. Three factors that might moderate this risk are considered: (a) the father's health and involvement with the child, (b) the course and timing of the mother's depression, and (c) characteristics of the child. Relevant issues are discussed, and promising directions for future research are suggested.

Risk for psychopathology in the children of depressed mothers: a developmental model for understanding mechanisms of transmission.

The purpose of the study was to assess the degree to which depressed mother-infant dyads, relative to nondepressed mother-infant dyads,matched behavior states on a continuous scale from negative to neutral to positive affect. Furthermore, interaction synchrony in these two groups was determined by measuring the coherence of the dyads' behavior time series

Behavior-State Matching and Synchrony in Mother-Infant Interactions of Nondepressed versus Depressed Dyads.

To determine whether the "depressed" behavior (e.g., less positive affect and lower activity level) of infants noted during interactions with their "depressed" mothers generalizes to their interactions with nondepressed adults, 74 3-6-month-old infants of "depressed" and nondepressed mothers were videotaped in face-to-face interactions with their mothers and with nondepressed female strangers. "Depressed" mothers and their infants received lower ratings on all behaviors than nondepressed mothers and infants. Although the infants of "depressed" versus nondepressed mothers also received lower ratings with the stranger adult, very few differences were noted between those infants' ratings when interacting with their mother versus the stranger, suggesting that their "depressed" style of interacting is not specific to their interactions with depressed mothers but generalizes to their interactions with nondepressed adults as early as 3 months of age.

Infants of depressed mothers show "depressed" behavior even with nondepressed adults.

Sharing and synchrony of behavior states and heart rate were assessed by spectral and cross-spectral analyses of the interaction data of 16 “depressed” and nondepressed mothers and their 3-month-old infants. The depressed mothers and their infants shared negative affective behavior states more often and positive behavior states less often than the nondepressed dyads. Cross-spectral analyses of the mothers' and infants' behavior and heart rate time series suggested the following: (a) greater coherence of mother-infant behavior states in nondepressed versus depressed dyads, with mothers leading at less than 1-s lags; (b) greater coherence of infant behavior/mother heart rate for the nondepressed versus depressed dyads; (c) no group differences for mother behavior/infant heart rate, for mother behavior/heart rate, for infant behavior/heart rate, or for mother/infant heart rate; and (d) greater coherence across partner behavior (mother/infant behavior) than within-partner behavior and physiology (mother behavior/heart rate or infant behavior/heart rate).

Sharing and synchrony of behavior states and heart rate in nondepressed versus depressed mother-infant interactions☆

Mothers who scored zero on the Beck Depression Inventory ( N = 25) were compared to “depressed” mothers (high scores on the Beck) ( N = 39) and nondepressed mothers ( N = 98) during face-to-face interactions with their 5-month-old infants. The interaction videotapes were rated on the Interaction Rating Scales and were coded second-by-second for attentive/affective behavior states. The zero Beck mothers and their infants received lower ratings and were in less positive behavior states (alone or together) than the high scoring Beck “depressed” mother/infant dyads and even more frequently than the nondepressed mother/infant dyads. The lower activity levels, lesser expressivity, and less frequent vocalizing were suggestive of “depressed” behavior in both the mothers and their infants. In addition, the infants of the zero Beck mothers had lower vagal tone and lower growth percentiles (weight, length, and head circumference) than the infants of nondepressed mothers, although they did not differ from the infants of depressed mothers on these measures. These data suggest that mothers who report no depressive symptoms may present as much, if not greater risk, for their infants than mothers who do report depressive symptoms on the Beck Depression Inventory.
