Positive behavioral synchrony (PBS) between mothers and children involves the bidirectional exchange of verbal and nonverbal communication. Respiratory sinus arrhythmia (RSA) synchrony reflects the concordance between mother-child physiological states. Both PBS and RSA synchrony can be undermined by psychopathology symptoms. Latinx and Black families may experience contextual stressors that contribute to heightened symptoms of psychopathology, yet minimal research has examined relations between psychopathology symptoms with PBS and RSA synchrony in these families. The present study assessed associations between maternal depressive and child internalizing symptoms, mother and child negative affect (NA), and PBS and RSA synchrony in a sample of 100 Latina and Black mothers (Mage  = 34.48 years, SD = 6.39 years) and their children (Mage  = 6.83 years, SD = 1.50 years). Dyads engaged in a video-recorded stress task where RSA was collected continuously. Videos were later coded for PBS and mother and child NA. Mothers reported on their depressive and child's internalizing symptoms. Maternal NA was associated with weak PBS and negative RSA synchrony. Neither depressive and internalizing symptoms nor child NA were associated with PBS or RSA synchrony. Results highlight the potency of maternal NA on behavioral and physiological synchrony in Latinx and Black families.

Socioemotional Development during Infancy01:30

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

Parenting Styles01:27

Parenting Styles

Diana Baumrind's four parenting styles — authoritarian, authoritative, neglectful, and permissive — each influence children's socio-emotional development differently.
Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Socioemotional Experience and Gender Development

Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...

Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Negative and Cognitive Symptoms of Schizophrenia01:30

Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...
