Jealousy 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. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

The primary objective of this research was to describe and analyze the behavior of children and identify factors that control the situation or did not respond. To collect data we used two sets of rules available commercially: Senha and Boole. Both games were applied to six male children, aged 8 years and 10 months and 10 years. The design was composed of two experimental conditions: the basic procedure and additional procedures. The procedure-based contained three levels of difficulty (level 1, level 2 and level 3), which were overcome by the issue of response-solution. The additional procedures were added when the participant failed to give the answer with the solution within the criteria proposed in the basic procedure. The responses of the participants determined the manipulations performed. The analysis of the behavior of children showed some manipulation of stimuli to encourage the issue of response-solution in each of the games. However, a manipulation that was central to both was the deduction, which was identified through verbal and nonverbal responses of participants. The difficulty encountered in making a deduction appeared in conditional sentences. Only one participant acted under control of conditional rules to solve the problem correctly. Password for the game, specifically, an aspect that was seen as relevant was linked to the fact that the participant can not or do inductions. The manipulation of variables being the center of this process, the deductions and inductions made by the participants, specifically the derivation and / or formulation of rules, may be regarded as directory prerequisite to problem-solving software. The lack or a failure in the implementation of such manipulation impossible to issue the response-solution for the individual, which could be demonstrated in the results presented. Whereas formal education seeks to train individuals able to solve problems, the results of research become important in that they point to intervening variables that allow the installation of a repertoire suitable for solving problems of logic / O processo comportamental da resolução de problemas lógicos consiste em, frente a um conjunto de condições, o indivíduo manipular variáveis (comportamentos preliminares) que alteram a situação ou o próprio indivíduo gerando estímulos discriminativos que controlam respostas posteriores, e analisar os dados decorrentes de tais manipulações possibilitando a emissão da resposta-solução. O objetivo primordial da presente pesquisa foi descrever e analisar o comportamento de crianças e identificar que elementos das situações controlam ou não o responder. Para coleta de dados foram utilizados dois jogos de regras disponíveis comercialmente: Senha e Jogos Boole. Ambos os jogos foram aplicados a seis crianças do sexo masculino, com idades entre 8 anos e 10 meses, e 10 anos completos. O delineamento foi composto por duas condições experimentais: procedimento-base e procedimentos adicionais. O procedimento-base continha três níveis de dificuldade (nível 1, nível 2 e nível 3), que eram superados pela emissão da resposta-solução. Os procedimentos adicionais foram inseridos quando o participante não conseguiu emitir a resposta-solução dentro dos critérios propostos no procedimento-base. As respostas dos participantes determinaram as manipulações realizadas. A análise do comportamento das crianças evidenciou algumas manipulações de estímulos que favoreceram a emissão da resposta-solução em cada um dos jogos. Porém, uma manipulação que se mostrou fundamental em ambos foi a dedução, que foi identificada através das respostas verbais e não verbais dos participantes. A dificuldade encontrada ao fazer uma dedução apareceu nas frases condicionais. Apenas um participante agiu sob controle de regras condicionais e conseguiu resolver o problema corretamente. Para o jogo Senha, especificamente, um aspecto que foi observado como relevante estava ligado ao fato do participante conseguir ou não fazer induções. Sendo a manipulação de variáveis o centro desse processo, as deduções e induções apresentadas pelos participantes, mais especificamente a derivação e/ou formulação de regras, podem ser consideradas como repertório pré-requisito para resolução de problemas lógicos. A falta ou uma falha na execução de tal manipulação impossibilitou a emissão da respostasolução pelo indivíduo, o que pôde ser demonstrado nos resultados apresentados. Considerando que a educação formal busca a formação de indivíduos capazes de resolver problemas, os resultados obtidos na pesquisa tornam-se importantes na medida em que apontam para variáveis intervenientes que possibilitam a instalação de um repertório adequado à resolução de problemas lógicos

No. of bitstreams: 1 Isabela Garcia Rosa Hispagnol.pdf: 844136 bytes, checksum: 26976ae19f0875a7298a15ef40b8bb85 (MD5) Previous issue date: 2017-10-16 / Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq / The relationship of care in early childhood is considered one of the most important aspect on the child’s physical and emotional development. The conditions under which this relationship occurs profoundly influence the child's construction of himself and the way he relates to the world around him. Adverse events such as violence, accidents, disasters, when perceived as a threat to life or physical integrity, impact not only the child who has experienced such a situation but also those who take care of her. This paper aims to understand the impact of a potentially traumatic situation on the care relationship, through the experience of the primary caregiver of a child up to twelve years of age who has experienced unintentional injury. The epistemology used was the Theory of Attachment developed by John Bowlby. It is a multiple case study with semi-structured interview to address the caregiver's experience. Three mothers of children between two and ten years of age participated in this qualitative study. From the result of the interviews the following categories of meanings were constructed: construction of the behavior of caring, which contemplated the internalized mother, the idealized mother and the possible mother; reactions and feelings at the moment and soon after the incident with the child; post-traumatic reactions; need to provide protection; balance between the various systems; the child's reactions to the event; new homeostasis among then. The changes regarding the caregiver system were related to certain factors such as: the previous emotional structure of the mother; the characteristics of the event; the perception of danger; and self-perception as a mother. The possible consequences for children's emotional development were also discussed. It was pointed out the necessity of new researches that approach this subject / A relação de cuidados na primeira infância é tida como primordial para o desenvolvimento físico e emocional do ser humano. As condições sob as quais esta relação ocorre influenciam profundamente a construção da criança acerca de si mesmo e o modo como se relaciona com o mundo a sua volta. Eventos adversos como violência, acidentes, desastres, quando percebidos como uma ameaça à vida ou à integridade física, impactam não só a criança que passou por tal situação como também a quem dela cuida. Este trabalho tem como objetivo compreender o impacto de uma situação potencialmente traumática na relação de cuidados, pela experiência do cuidador principal de uma criança de até doze anos que tenha passado por uma situação de ferimentos não intencionais. A epistemologia utilizada foi a Teoria do Apego desenvolvida por John Bowlby. Trata-se de um estudo de casos múltiplos instrumentos, com entrevista semidirigida para abordar a experiência do cuidador. Três mães de crianças entre dois e dez anos participaram deste estudo qualitativo. A partir do resultado das entrevistas foram construídas as seguintes categorias de significados: construção do comportamento de cuidar, que contemplou a mãe internalizada, a mãe idealizada e a mãe possível; as reações e os sentimentos no momento e logo apos o incidente com a criança; as reações póstraumáticas; a necessidade de dar proteção; o equilíbrio entre os diversos sistemas; as reações da criança ao evento; nova homeostase da dupla. As mudanças com relação ao sistema cuidador estavam relacionadas a determinados fatores como: a estrutura emocional prévia da mãe; as características do evento; a percepção de perigo; e a autopercepção como mãe. Foram discutidas as possíveis consequências para o desenvolvimento emocional das crianças, bem como foi apontada a necessidade de novas pesquisas que abordem este tema

Family Child Care Homes (FCCHs) are the second largest provider of non-relative care in the U.S. However, despite providing care for nearly 1.9 million children under the age of 5, little is known about the physical activity levels of children attending FCCHs. This dissertation sought to provide new information with regards to physical activity in children attending FCCHs. The purpose of the first study was to objectively measure physical activity in children attending FCCHs. 114 children (60 boys and 54 girls) 3.7 �� 1.1 years of age from 47 FCCHs wore an ActiGraph GT1M accelerometer for the duration of child care attendance during a randomly selected week. Counts were classified as sedentary (SED), light (LPA), or moderate-to-vigorous (MVPA) using the cut-points developed by Pate et al. (2006). Total physical activity was calculated by summing time spent in LPA and MVPA. Non-wear time was estimated by summing the number of consecutive zero counts accumulated in strings of 10 minutes or longer. Children were included in the analyses if they had 2 or more monitoring days in which wear time was ���75% of the attendance time. On average, children accumulated 25.9 �� 5.7 min of SED, 10.1 �� 4.2 min of MVPA, and 34.1 �� 5.7 min of total physical activity per hour of attendance. Further analysis revealed that among healthy weight children, 4 year-olds exhibited significantly lower levels of SED and significantly higher levels of MVPA and total physical activity than 2- and 3- year-olds. Among 4-year-olds, overweight and obese children exhibited significantly higher levels of SED and significantly lower levels of MVPA and total PHYSICAL ACTIVITY than healthy weight counterparts. The results from this study indicated that preschool-aged children attending FCCHs are mostly sedentary and accumulate low levels of MVPA during the child care day. The purpose of the second study was to assess the validity of two proxy report instruments designed to measure physical activity in children attending FCCHs. Valid self-report measures are needed for large scale intervention studies and/or population-based surveillance studies in which more burdensome objective measures are not feasible. In Year 1 of the study, FCCH Providers (N=37) completed the Burdette parent proxy report, modified for the family child care setting, for 107 children aged 3.4 �� 1.2 years. In Year 2, 42 Providers completed the Harro parent and teacher proxy report, modified for the family child care setting, for 131 children aged 3.8 �� 1.3 years. Both proxy-reports were assessed for validity using objectively measured physical activity as a criterion measure (accelerometry). Significant positive correlations were observed between scores from the modified Burdette proxy report and objectively measured total physical activity (r = 0.31, p < 0.01) and MVPA (r = 0.33, p < 0.01). Across levels of Provider-reported activity, both total physical activity and MVPA increased significantly in a linear dose-response fashion. Provider-reported MVPA scores from modified Harro proxy report were not associated with objectively measured physical activity. These findings suggested that the modified Burdette proxy report may be a useful measurement tool in larger-scale physical activity studies involving FCCHs in which objective measures, such as direct observation or accelerometry, are not practical. The purpose of the third study was to evaluate the effects of two strategies to increase the use of portable play equipment in FCCHs ��� a community-based train-the-trainer physical activity intervention (INT), and the same trainer-the-trainer intervention supplemented with monthly emails promoting the use of portable play equipment (INT+). We hypothesized that Providers completing the standard train-the-trainer intervention would report significantly greater portable play equipment use than Providers completing the food allergy control training (CON). We further hypothesized that Providers completing the supplementary email intervention would report significantly greater portable play equipment use than Providers completing standard train-the-trainer intervention or the food allergy control training. A total of 50 FCCH Providers from Marion, Linn, Benton, Washington, and Lane County, Oregon were randomized to the INT or CON conditions. Twelve Providers from Lincoln County were assigned to the (INT+). The type, variety, and frequency of portable play equipment use was measured by means of self-report via a checklist and two items from the previously validated NAP-SACC Self-Assessment instrument. FCCH Providers who completed the INT reported significantly greater use of portable play equipment than Providers completing the CON training. However, portable play equipment use among Providers completing the INT+ was not significantly different from that reported by Providers in the INT or CON. Notably, neither intervention had a significant impact on the amount or variety of portable play equipment. The results showed that a comprehensive trainer-the-trainer intervention to increase physical activity in FCCHs could successfully increase the use of portable play equipment in the home. However, supplementing the intervention with monthly emails encouraging the use of PPE was not effective. / Graduation date: 2013

This study addresses young children's involvement with comfort objects, including why children have them, how they are used, when attachments to such objects are cause for concern and how teachers and parents can respond to promote the young child's development. The child's becoming and development is examined in this study. The researcher also reviews major transitional object theories in terms of origin, development and psychological meaning. This study aims to explore this phenomenon from a psychological - educational perspective and to formulate a set of guidelines for parents and professionals whose children use comfort behaviour. Information was collated from case studies, a questionnaire and a detailed study of literature. / Psychology of Education / M. Ed. (Guidance and Counselling)
