Title: Infant Socioemotional Responses When Faced with Social Threat: Implications For Neurophysiological and Bio-hormonal Processing.
Creator: Bernardo, Angela Maria, Jones, Nancy Aaron, Florida Atlantic University, Department of Psychology, Charles E. Schmidt College of Science
Abstract/Description: Infants have an innate desire to form social bonds and jealousy protests are an attempt to regain exclusive maternal attention from a social usurper. The current study examined neurophysiological and bio-hormonal processes related to jealousy responses during the first year and a half of life. Prior to and after the first year of life, infants express jealousy protest behavior when faced with a social threat.

Show moreInfants have an innate desire to form social bonds and jealousy protests are an attempt to regain exclusive maternal attention from a social usurper. The current study examined neurophysiological and bio-hormonal processes related to jealousy responses during the first year and a half of life. Prior to and after the first year of life, infants express jealousy protest behavior when faced with a social threat. Resting-state frontal EEG coherence indicated a developmental shift from bilateral connectivity in younger infants to increased frontal specialization in older infants in relation to jealousy responses. Furthermore, 6- to 9-month-old infants exhibited more frontal neuroconnectivity in the right hemisphere (i.e., an area related to negative emotions) of the brain compared to left when faced with social threat. Lastly, social threat activated HPA reactivity in infants higher in temperamental distress. This study provides further evidence for the emerging links between physiological and socioemotional responses in infancy due to loss of exclusive maternal attention.

Title: DEVELOPMENT OF INFANT AGENCY.
Creator: Sloan, Aliza T., Jones, Nancy Aaron, Kelso, J. A. Scott, Florida Atlantic University, Department of Psychology, Charles E. Schmidt College of Science
Abstract/Description: The mobile conjugate reinforcement (MCR) paradigm, made famous by Carolyn Rovee-Collier and her colleagues (Rovee & Rovee, 1969), has long been used to study infant learning and memory. In MCR studies, the infant's foot is tethered to a mobile hanging overhead, and the mobile responds directly to the infant's kicking. Infant kicking rate triples within a few minutes of interacting with the mobile. This result was classically interpreted as evidence of reinforcement learning. Kelso and Fuchs ...
Show moreThe mobile conjugate reinforcement (MCR) paradigm, made famous by Carolyn Rovee-Collier and her colleagues (Rovee & Rovee, 1969), has long been used to study infant learning and memory. In MCR studies, the infant's foot is tethered to a mobile hanging overhead, and the mobile responds directly to the infant's kicking. Infant kicking rate triples within a few minutes of interacting with the mobile. This result was classically interpreted as evidence of reinforcement learning. Kelso and Fuchs (2016) reinterpreted it as evidence that a coordinative structure, or functional synergy, forms between infant and mobile, triggering a positive feedback loop between the two. Positive feedback is proposed to give rise to an `Aha!' moment as the (prelinguistic) infant suddenly realizes it is an agent in control of the mobile's motion. While some have theorized the realization of self as causal agent emerges from organism-environment interactions, Kelso and Fuchs (2016) developed a mathematical model of the coordination dynamics between the infant and mobile, providing mechanistic explanations for the formation of agency. The current study was the first to measure movement of the mobile and analyze how dynamics of coordination between infant and mobile relate to possible transitions from spontaneous to intentional action. Novel measures of infant and mobile dynamics were used to test model predictions. Infant activity dropped drastically in response to non-contingent mobile movement and remained suppressed at the start of infant~mobile contingency, suggesting that mobile movement triggers a qualitatively different context for infants. This finding challenges the widely held assumption that mobile movement rewards and stimulates infant movement and calls into question the sufficiency of standard contingency detection cut-offs and explanations of conjugate reinforcement learning. Assessing coordination dynamics on a fine time scale using new analytical techniques made it possible to identify moments of agentive realization. Approaching agency as a relational phenomenon allowed for detailed characterization of the infant~mobile relationship and its role in the emergence of causal agency. In addition, the results revealed a number of surprising insights into agency formation such as the critical role of inactivity for agentive discovery and the possibility of intermediary stages or quasi-agentive states.

Title: Infants' perception of synthetic-like multisensory relations.
Creator: Minar, Nicholas J., Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: Studies have shown that human infants can integrate the multisensory attributes of their world and, thus, have coherent perceptual experiences. Multisensory attributes can either specify non-arbitrary (e.g., amodal stimulus/event properties and typical relations) or arbitrary properties (e.g., visuospatial height and pitch). The goal of the current study was to expand on Walker et al.'s (2010) finding that 4-month-old infants looked longer at rising/falling objects when accompanied by rising...

Multisensory attributes can either specify non-arbitrary (e.g., amodal stimulus/event properties and typical relations) or arbitrary properties (e.g., visuospatial height and pitch). The goal of the current study was to expand on Walker et al.'s (2010) finding that 4-month-old infants looked longer at rising/falling objects when accompanied by rising/falling pitch than when accompanied by falling/rising pitch. We did so by conducting two experiments. In Experiment 1, our procedure matched Walker et al.'s (2010) single screen presentation while in Experiment 2 we used a multisensory paired-preference procedure. Additionally, we examined infants' responsiveness to these synesthetic-like events at multiple ages throughout development (four, six, and 12 months of age). ... In sum, our findings indicate that the ability to match changing visuospatial height with rising/falling pitch does not emerge until the end of the first year of life and throw into doubt Walker et al.'s (2010) claim that 4-month-old infants perceive audiovisual synesthetic relations in a manner similar to adults.

Title: Multisensory Cues Facilitate Infants’ Ability to Discriminate Other-Race Faces.
Creator: Minar, Nicholas J., Bjorklund, David F., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: Our everyday world consists of people and objects that are usually specified by dynamic and concurrent auditory and visual attributes, which is known to increase perceptual salience and, therefore, facilitate learning and discrimination in infancy.

Show moreOur everyday world consists of people and objects that are usually specified by dynamic and concurrent auditory and visual attributes, which is known to increase perceptual salience and, therefore, facilitate learning and discrimination in infancy. Interestingly, early experience with faces and vocalizations has two seemingly opposite effects during the first year of life, 1) it enables infants to gradually acquire perceptual expertise for the faces and vocalizations of their own race and, 2) it narrows their ability to discriminate the faces of other-race faces (Kelly et al., 2007). It is not known whether multisensory redundancy might help older infants overcome the other-race effect reported in previous studies. The current project investigated infant discrimination of dynamic and vocalizing other-race faces in younger and older infants using habituation and eye-tracking methodologies. Experiment 1 examined 4-6 and 10-12-month-old infants' ability to discriminate either a native or non-native face articulating the syllable /a/. Results showed that both the 4-6- and the 10-12-month-olds successfully discriminated the faces,regardless of whether they were same- or other-race faces. Experiment 2 investigated the contribution of auditory speech cues by repeating Experiment 1 but in silence. Results showed that only the 10-12-month-olds tested with native-race faces successfully discriminated them. Experiment 3 investigated whether it was speech per se or sound in general that facilitated discrimination of the other-race faces in Experiment 1 by presenting a synchronous, computer-generated "boing" sound instead of audible speech cues. Results indicated that the 4-6-month olds discriminated both types of faces but that 10-12-month-olds only discriminated own-race faces. These results indicate that auditory cues, along with dynamic visual cues, can help infants overcome the effects of previously reported narrowing and facilitate discrimination of other-race static, silent faces. Critically, our results show that older infants can overcome the other race-effect when dynamic faces are accompanied by speech but not when they are accompanied by non- speech cues. Overall, a generalized auditory facilitation effect was found as a result of multisensory speech. Moreover, our findings suggest that infants' ability to process other- race faces following perceptual narrowing is more plastic than previously thought.

Title: Infant Jealousy Responses: Temperament and EEG.
Creator: Mize, Krystal D., Florida Atlantic University, Jones, Nancy Aaron, Bjorklund, David F., Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: Jealousy results from the fear of loss of an important relationship partner or his/her exclusive attention (Neu, 1980; Tov-Ruach, 1980). Infants are dependant on their caregivers for basic needs and emotional support.

Show moreJealousy results from the fear of loss of an important relationship partner or his/her exclusive attention (Neu, 1980; Tov-Ruach, 1980). Infants are dependant on their caregivers for basic needs and emotional support. Therefore, if an infant perceives that a rival threatens the parent-child dyad relationship, it is possible that the infant will respond in a jealous manner just as adults do when their important relationships are threatened . Although infants have limited emotional understanding, Palmer and Palmer (2002) suggest that jealousy evolved out of other resource-protecting drives. Because parental care is a valuable resource, supporting survival, infants may have at least precursory jealousy capabilities. Research on infant jealousy is minimal however, Hart and Carrington (2002) characterized approach responses to the loss of maternal attention to a life-like doll as jealousy. The purpose ofthe current repeated-measures research design is to provide a conceptual replication of previous infant jealousy research. Whether infant jealousy responses are moderated by individuals approach or withdrawal tendencies, is still to be determined and is another focus of the current research. Temperamental characteristics may influence emotional responses and asymmetrical frontal brain activity is associated with individual differences in emotional responding (see Coan & Allen, 2004 for a review). Therefore baseline electroencephalography (EEG) is collected in the current research followed by subjecting 15 infants (mean age = 12.87 months) to two maternal ignoring conditions, one involving the mother attending to a social object (lifelike doll) and a control condition in which the mother attends to a non-social object (book). Results show that infants respond differentially to the two conditions with increased approach behaviors, arousal, and negative affect in the doll condition. The infants' responses in the social-object condition are identified as jealousy, suggesting that infants are capable of at least some complex emotional experiences. v

Show moreJealousy is a response to a situation in which a person feels a combination of different emotions, such as love, anger, sadness and fear when an affectionate interaction is happening between a loved one and someone else. This paper discusses the definition and onset of infant jealousy, the physiological basis of jealousy, whether maternal factors play a role, as well as studies on jealousy and EEG patterns. It has been argued that infants, as young as six-months-old display jealous-like behaviors. During jealousy evocation conditions, infants demonstrate negative emotions such as protesting or crying, diminished distancing, and heightened gaze toward their mother during maternal inattention. Approach/withdrawal behaviors and electroencephalography (EEG) activation were studied in the context of an infant jealousy paradigm. In this investigation, 45 mother-infants dyads were exposed to a social versus non-social condition during maternal inattention. During the social condition, infants demonstrated increased approach-style gaze and reach and negative affect. EEG was collected during all conditions on a subsample of 15 infants and in agreement with adult jealousy literature (Harmon-Jones, Peterson, & Harris, 2009), infants displayed left midfrontal EEG asymmetry, and displayed more approach motivations during the social doll condition indicative of jealousy approach motivations.

Title: Kangaroo care with full-term infants: maternal behaviors and mother-infant bonding.

Current research on the maternal benefits of kangaroo care is scarce, primarily focuses on early KC, and is mostly qualitative in nature (Fegran, Helseth, & Fagermoan, 2008; Matos et al., 2010). The present study examined the effect of late KC on maternal behaviors, sensitivity, and mother-infant interactive mutuality when infants were 3 months of age. Mothers who used kangaroo care as directed were found to have greater bonding scores and less anxiety about caring for their infants as measured through the Postpartum Bonding Questionnaire. Kangaroo care was also found to have an effect on mothers’ ability to effectively calm their infants after an arm restraint task. Further research on the usefulness of late intermittent KC with full-term infants is needed.

While a large body of research connecting maternal depression to infant EEG asymmetry exists, the current study sought to add to the sparse literature on maternal anxiety and infant EEG. Mother-infant dyads were assessed prenatally during the third trimester, soon after birth, at 6 weeks and 3 months postnatal. Association between maternal depression and later development of right mid-frontal alpha asymmetry was confirmed, while trends suggested maternal anxiety may be associated with lateral frontal alpha asymmetry. Greater maternal sensitivity and anxiety were each associated with lower post-stressor cortisol in infants with right frontal asymmetry. Greater time spent in mutual gaze was associated with positive infant affect. Finally, quality mother-infant dynamics encourage positive infant affect and healthy physiological stress regulation even when brain patterns associated with dysregulation have been established.

Show moreThe current study examined the effects of kangaroo care on breastfeeding practices, infant stress reactivity, and biobehavioral measures of mother-infant bonding across the first 3 months postpartum. Additionally, the role of breastfeeding in infant cortical maturation in the frontal lobe was examined. Thirty two mother-infant dyads participated in the current study; 16 mother-infant dyads were randomly assigned to the kangaroo care group and 17 mother-infant dyads were assigned to the control group. Mothers in the kangaroo care group received training on proper kangaroo care procedures by a trained administrator during the first 1-2 weeks postpartum. Mothers in the kangaroo care group were asked to use the kangaroo care procedure for 1 hour per day for 6 weeks. Maternal perceptions of fetal attachment, mood, feeding intentions, and urinary oxytocin measurements were assessed prenatally. At a newborn visit, infant neurobehavioral functioning and urinary oxytocin measurements were assessed. Maternal mood and feeding practices were also assessed at the newborn visit. At 3 months postpartum, mother-infant dyads were assessed on urinary oxytocin measurements. Mother-infant dyads were recorded during a play session and feeding session. Infant baseline EEG recordings were taken over a 5 minute period. Infant cortisol measurements were collected from infant saliva before and after a mild behavioral stressor, an infant arm restraint procedure. Maternal perceptions of postpartum bonding, mood, infant temperament, and feeding practices were also assessed. Results indicate that kangaroo care produced medium to large effects on cortisol reactivity, dyadic bonding, and breastfeeding practices if kangaroo care was practiced for the recommended amount of time. Kangaroo care produced medium to large effects on oxytocin levels in motherinfant dyads regardless of use. Cortical measures of infant frontal activity indicated that all infants in the samples displayed functional maturity of the frontal lobe. Kangaroo care can be used a viable, low-cost tactile procedure that can be implemented after birth to aid in breastfeeding practices, mother-infant bonding, and lower infant stress reactivity. Infants in the study who received at least one breastfeeding session displayed advanced patterns of frontal activation. Further study is needed to determine if peripheral oxytocin measurements are 1) reliable and 2) are indicative of dyadic bonding behaviors.

Show moreJealousy is understood as a system of physiological, behavioral, and emotional responses, yet few studies have examined these aspects of jealousy simultaneously in infants. Further, jealousy paradigms have not been examined as a potential stressor in infancy and thus typical cortisol reactivity and regulation patterns in response to jealousy paradigms have not been observed. In addition, the contribution of attachment security to infant expressions of jealousy has been vastly understudied. The present study seeks to fill the current gaps in the infant jealousy literature by investigating quantitative and qualitative changes in infant jealousy across the first two years of life. Data was collected longitudinally and mother- infant dyads were asked to participate when infants were 12- months and 24-months of age. Associations between behavioral jealousy responses, baseline EEG activity, stress reactivity and attachment security were examined. Differences in approach behaviors and behavioral arousal were found across conditions and were consistent with previous studies (Hart & Carrington, 2002; Mize & Jones, 2012). Findings relating to EEG activity pointed to a relationship between left EEG asymmetry and global approach behaviors across time. Cortisol reactivity was found to be associated with attachment security but reactive cortisol concentrations compared to baseline cortisol concentrations do not indicate that the paradigm was an effective stressor. Attachment security was found to be associated with proximity behaviors in 12- month olds but not 24-month olds. Finally, a linear regression revealed that attachment security, EEG asymmetry, and cortisol reactivity at 12-months are significant predictors of behavioral jealousy responses at 24-months. Changes in behavioral and physiological measures across time indicate that jealousy continues to develop during the second year of life but may have different underlying processes than the processes that contribute to jealousy expression in 12-month-olds.
