Welcome to the WAVES Laboratory
Welcome to the WAVES Emotion Lab at Florida Atlantic University!
The purpose of the WAVES Emotion Lab is to understand the factors that contribute
to the development of socio-emotional Wellness during infancy and childhood. Our
focus is on investigating the physiological and behavioral underpinnings of Affective
development. Recognizing the Value of parental socialization practices, we strive to
investigate Emotions that contribute to the development of optimal Socio-emotional
Current theories and research into brain development note that the frontal lobes
continue to develop throughout early childhood. Our goal is to examine the factors
that contribute to risk and resilience in the development of emotional response.
Individual differences in temperament and social interactive attachments to parents
impact the trajectory to emotionally competent functioning during childhood. Our research,
funded in part by the National Institutes of Mental Health, is designed to explore and
understand the contributors to optimal infant and child development.
Nancy Aaron Jones is an Associate Professor of Psychology and Biomedical Science. She directs the WAVES Emotion Lab,
which investigates biological and socio-emotional factors that influence development, specifically focusing on the processes
by which individual differences in emotional resilience and maternal psychopathology influences infant and childhood
development. Dr. Jones' research is built on the developmental psychophysiological theory that both biological and social factors
interact during development and influence our emotional lives. E-mail: email@example.com
Krystal D. Mize, Ph.D. graduated from FAU’s Evolutionary Psychology program in 2008. Her graduate research centered on the evolved
nature of jealousy. Specifically her thesis work focused on homicide between intimate partners (an extreme outcome of jealousy) and her
dissertation project was on affective and behavioral responses to the loss of maternal attention to a social rival (infant jealousy).
Dr. Mize’s research interests are eclectic. Beyond her extensive involvement in the WAVES Emotion Lab research, Dr. Mize is interested
in a variety of other interpersonal relationship issues, including differential parental investment, romantic and sexual relationships,
and intra-sexual competition. She is interested in religious beliefs, greed and denial as they are related to environmental values as well.
Although her research interests are diverse, the overarching theme to Dr. Mize's work is examining the evolved psychology underlying behaviors.
Dr. Mize works with the WAVES Emotion Lab as a Senior Research Manager, overseeing much of the research that goes on in the laboratory.
Aviva Pessoa (on leave)
Aviva Pessoa, M.A. earned her bachelor’s degree in Psychology from Tulane University in 2002. She earned her Master’s in April after
completing data analysis associated with part one of the emotion socialization study. Aviva’s main research interest involve the role parents
play in the development of emotions in early childhood with an emphasis on the complex system that defines the relationship between parents
and children in the development of emotion. In particular, she is interested in the development of optimal emotion regulation and the physiological
systems which underlie selective attention to emotional information conveyed by parents. E-mail: firstname.lastname@example.org
Jillian Hardin worked as an undergraduate RA in the WAVES Emotion Lab and is currently a Ph.D. student in the lab. She oversees the Kangaroo Care
Project, which examines how touch and breastfeeding facilitate mother-infant bonding and the development of optimal physiological patterns in
infancy. Her research interests include the effects of maternal depression on infants and the role of breastfeeding in buffering impaired mother-infant
communication in these dyads. E-mail: email@example.com
Maria Corbett is a Ph.D. student in neuroscience. Her major interests are to study interventions that reduce psychological stress and anxiety in
school aged children. The human responses to stress and anxiety are twofold, often involving a physiological and an emotional component. Maria's current
research goals are to investigate if a correlation exists between self reported measures of anxiety and the amount of cortisol released into the system.
Cortisol is one of the main stress hormones released by the hypothalamic pituitary adrenal axis (known commonly as the 'stress access'. Sustained
hyper-activation of this system can lead to long term deleterious effects that manifest behaviorally as health problems. Additionally, sustained exposure
to cortisol and other corticosteroids have deleterious effects on the health of neurons at the cellular level. Maria's research is examining if a
'mindfulness meditation' intervention can impact the two components of stress response; the emotional reporting of it and its physiological manifestations
as measures by salivary cortisol samples. We are hoping that mindfulness meditation, an empirically supported stress and anxiety reducer in adults, can help
to modulate both of these in school aged children. Specifically, we will be taking 3 cortisol samples at distinct time points, as well as pre and post
intervention measures of attention / executive function, emotional regulation, state/trait anxiety, test anxiety, and mindfulness. E-mail: firstname.lastname@example.org
Melannie Pineda is a new doctoral student in the lab. She graduated from FAU and completed her undergraduate Honor's Thesis project in the WAVES lab. Melannie's
thesis project involved looking at the stability of EEG and jealousy responses in infants between the ages of 9-months and 12-months of age. For her Master's
thesis, Melannie would like to branch out to study the role of oxytocin and cortisol in early development. E-mail: email@example.com.
Sarah Worch joined the lab as a volunteer and is currently a new Master's level student at FAU. Her thesis research with the lab is focused on changes in creativity levels
as a function of 10-weeks of meditation practice in school age children. E-mail: TBA

Emotions are ubiquitous and impart meaning to everyday experiences and social interactions. Our lab focuses on studying the development of emotions from infancy
through early childhood, employing neuro- and psychophysiological perspectives. We study the factors that precipitate both risk and resilience during development. We
are particularly interested in individual differences in temperament that are associated with positive emotions, approach styles and pro-social behaviors which are
likely to improve social relationships and developmental outcomes. We also study how maternal depression and mood influences infant and child development as well as
how family support can attenuate those risk factors.
We currently are recruiting participants for the following important studies:
- Early and Extended Touch Intervention on Mother-Infant Bonding
The objective of this study is to examine the effects of early touch (Kangaroo Care, KC) and extended touch through stable breastfeeding patterns on infant
physiological and behavioral regulation in a group of depressed and non-depressed mothers and their infants. We are examining oxytocin levels in mothers during
the prenatal and postnatal times as well as taking measures of mother-infant bonding and emotional interactive experiences. Infants are evaluated behaviorally
and physiologically several times during the first months of life. Our ultimate goal is to uncover the factors that precipitate optimal dyadic interactions
(bonding) and infant physiological functioning during early development in order to attenuate interactive problems that may occur in depressed mother-infant dyads.

- Infant Jealousy
The infant jealousy project examines infant's emotional responses to the loss of their mothers’ exclusive attention in two conditions, when she attends to a social
item and when she attends to a non-social item. Several studies are underway in the lab on this topic with the aim of examining behavioral and physiological (EEG)
responses to the loss of maternal attention.
- 12-month study: The first study is designed to explore temperamental factors, including tonic EEG activity as it relates to the infant’s emotional
responses in 12-month infants.
- 9-month study: The second study is an extension of the former one, designed to further evaluate the physiological responses of younger infants during
the loss of their mother's exclusive attention to a social rival relative to a non-social rival.
- The third element of this research is to evaluate the longitudingal physiological patterns and behavioral stability of responses to the loss of maternal attention
as infants approach their first birthday. We also hope to examine the effects of maternal mood on the development of the brain and infant emotions during these early
- Meditation and Physiology
The primary objective of this research is to evaluate the effects of meditation on children’s emotional well-being and physiological development using a pre- and
post-manipulation research design. Several projects are in progress based on this study. Currently, the EEG and cortisol data for our ongoing meditation research is
under analysis. Additionally, we have a new meditation study involving pre-adolescent children begining in fall 2012. The goal of this new study is to extend on our
previous protocol by exploring heart rate recovery as a function of engaging in 10-weeks of meditation practice.
The following studies are being prepared for future theses or publications:
- Victimization Research
The victimization research is designed to investigating factors that contribute to aggression in children. Specifically, we are interested in physiological correlates
of aggression and victimization via autonomic reactivity during baseline and mild stress related events. Three main questions are being examined in this study. The first
goal of this study is to determine if there are physiological differences in highly aggressive versus highly victimized children. Next, we are evaluating if any
differences in these temperaments affect feelings about empathy. The final focus of the victimization research is on whether or not there are specific types of
aggression associated with lower levels of arousal. The overarching aim of this line of research is to create a psychophysiological profile of aggressive and victimized
children as a means of better assessing the etiology of these behaviors, with the ultimate goal of developing optimal intervention strategies to prevent violence in schools.
- Newborn Empathy Research
Humans may be predisposed, both physiologically and behaviorally, to respond to others who are in distress (Eisenberg et al., 2001; Hoffman, 2000). Mirror neurons fire
both when an individual experiences an event and when they witnesses the event occurring to another individual (Preston & deWaal, 2002). Therefore, mirror neurons may
serve as a mechanism for a biological preparedness for empathic responding. In fact, Jones (2012) has shown that even newborns respond to another’s distress and that this
is related to individual differences in temperamental reactivity.Heart rate (HR), Heart period (HP), and heart rate variability (HRV) are related to the behavioral
dimensions of reactivity and self-regulation (Bar-Haim, Marshall & Fox, 2000; Porges 1974) and have been shown to be dependable and stable measures of autonomic nervous
system response. Maternal depression has been associated with dysregulated emotional reactivity and regulation during infancy and potentially affects the physiological and
behavioral responses of a neonate (i.e., Field et al., 2007). The present research examines the relationship between neonates’physiological and behavioral responses to real
and digitally modulated distress sounds of other neonates as a function of maternal depression.
- Breastfeeding Research
There are several research projects in the WAVES Emotion Lab that involve breastfeeding. Feeding method, breast versus bottle, has been shown to support neurodevelopmental
trajectories in infancy (Jing, Gilchrist, Badger, & Pivik, 2010). Optimal neurodevelopment underlies healthy emotional patterns in early development.
- The present study examines the effect of different feeding patterns in relation to infant’s brain development through an examination of EEG coherence. EEG coherence
is a measure of the connectivity between different regions of the brain; specifically, it is a measure of the relationship of two different electrode sites at a specific
frequency band (Fox et al., 2004). Findings from the study indicate that infants who are breast fed show more mature brain development compared to infants who are fed
milk formulas, with infants who are breast fed for longer durations receiving greater benefits over those who are breast fed for shorter durations.
- Previous research (Smith & Ellwood, 2011) that examined socio-emotional interaction for infants who are breastfed has demonstrated optimal developmental outcomes
yet this has not been studied in infants of depressed mothers. Infants of depressed mothers show deficits in emotional processing as well as dysregulated interactive
patterns with their mothers. The early postnatal period (Fox & Rutter, 2011) has been implicated as a sensitive period for infant brain and behavioral development.
Therefore, deficits in processing and dyadic interactive patterns may be attenuated if interventions are implemented early in the postpartum months. Breastfeeding can
facilitate the establishment of positive mother-infant interaction patterns, which is important for optimal infant development (Field, 1992). Furthermore, Smith and Ellwood
(2011) suggest that breastfeeding increases maternal-infant contact resulting in enhanced psychological and physiological development as well as attachment. The purpose
of this study is to determine if stable breastfeeding patterns can protect infants of depressed mothers from the negative socio-interactive patterns normally observed in
depressed mother-infant dyads and ultimately lead to a healthier trajectory of socio-emotional development.
- Preschool Moral/Empathy Development Research
The preschool moral/empathy development research is a two-part, short-term longitudinal study investigating the effects of maternal and paternal mood and depression status on
the development of empathy in children. We are investigating whether child temperament and parental mood and emotionally-valenced interactive style influence the development of
prosocial/helping responses, like empathy.
- Part 1- ECG and emotional interaction
This portion of the study takes place in the home of the participant. Parents are asked to complete several questionnaires, including an assessment of family emotional
interaction, a depression inventory, and a demographic form. They then participate in a happy and sad story-reading task with their child while we monitor the child’s
heart rate (using portable ECG equipment). Both mothers and fathers participate!
- Emotion Socialization
The emotion socialization study grew out of the preschool study. This study extends these research efforts to examine familial influences on the child’s
understanding of emotions which are based on parental practices and interactive style. Emotion socialization has been a hot topic in the study of emotions
in early childhood. Parental expressivity, responsiveness, emotion coaching, the quality of parent-child interaction, and their relationship with young children’s
emotion regulation and affect-based cognitive understanding are the factors examined in this research
- Part 2- EEG and prosocial behaviors
This portion of the study takes place in our laboratory located on the FAU campus in Jupiter, FL. The mother is asked to complete several self- and child-report surveys,
including an assessment of maternal mood and child expressive vocabulary. The child’s brain activity is monitored using non-invasive EEG equipment while participating in an
emotion-inducing movie-watching task. We also evaluate the child’s responses to two helping/prosocial tasks.
