Infants have an innate desire to form social bonds and jealousy protests are observed when an infant is trying to regain attention lost by a caregiver to a social competitor. The current study examined jealousy responses during the first year of life, between 6- to 9-months of age and 12- to 18-months of age, in response to loss of exclusive maternal attention, in addition to exploring implications for mother-infant attachment, EEG asymmetry, and cortisol reactivity and regulation.

The current study examined jealousy responses during the first year of life, between 6- to 9-months of age and 12- to 18-months of age, in response to loss of exclusive maternal attention, in addition to exploring implications for mother-infant attachment, EEG asymmetry, and cortisol reactivity and regulation. At both age groups, infants demonstrated increased approach behaviors when infants are faced with a social rival, in addition, left-frontal EEG asymmetry was associated with maternal-directed approach behaviors during the social rival condition. In the 6- to 9-month sample, left-frontal EEG asymmetry also demonstrated an association with infants regulatory abilities, measured by salivary cortisol. This study provides further evidence for the emerging links between social and emotional responses in infancy due to loss of exclusive maternal attention.

- 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. 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 .

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

Kangaroo care (KC), has been shown to promote healthy development for both pre-term and full-term infants, and to improve mother-infant bonding (Ludington-Hoe, 2011; Charpak et al., 2005). 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).

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.

Jealousy 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.

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.

Show morePrenatal maternal stress and mood, and early postnatal mother-infant interactions set the stage for the child’s psychobiological, neurological and social development. 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.

Children exhibit neotenous, or physically immature, features, such as a large rounded head relative to body size, adult-sized eyes, round cheeks, a small chin, and a short narrow nose. Bowlby (1969) and others (Eibl-Eibesfeldt, 1989; Hrdy, 2005) propose that, in species whose young depend on care from an adult, these features could enhance offspring survival.

Lorenz (1943) argued that adult humans are particularly attracted to these features, and that these characteristics, which he termed Kindchenschema or “baby schema,” trigger a cognitive system that processes and reacts specifically to infantile features for the purpose of enhancing motivation to engage in caretaking behaviors. The goal of the studies proposed here is to examine the behavioral, attentional, and emotional effects of baby schema.
