La anemia en niños menores de tres años es un problema de salud pública en el Perú y el mundo. Se estima que la causa principal de la anemia, aunque no la única, es la deficiencia de hierro. Existen muchos estudios y revisiones sobre cómo esta carencia en los infantes impacta negativamente en el desarrollo psicomotor y, a pesar de corregirse la anemia, los niños con este antecedente presentan, a largo plazo, un menor desempeño en las áreas cognitiva, social y emocional. Estos hallazgos se describen en estudios observacionales, de seguimiento, así como en experimentales con grupo control. La anemia puede disminuir el desempeño escolar, y la productividad en la vida adulta, afectando la calidad de vida, y en general la economía de las personas afectadas. Se describen algunos posibles mecanismos de cómo la deficiencia de hierro, con o sin anemia, podría afectar el desarrollo en la infancia; por ello, causa preocupación la alta prevalencia de anemia que se observa en este grupo de edad. La prevención de la anemia en el primer año de vida debe ser la meta para evitar consecuencias en el desarrollo de la persona a largo plazo. / Anemia in children younger than 3 years is a public health problem in Peru and worldwide. It is believed that one of the primary causes of anemia is iron deficiency. Numerous studies and reviews have reported that iron deficiency limited psychomotor development in children and that, despite the correction of anemia, children with iron deficiency experienced poorer long-term performance in cognitive, social, and emotional functioning. These outcomes were reported in observational studies, follow-up studies, and experimental studies with a control group. Anemia can decrease school performance, productivity in adult life, quality of life, and the general income of affected individuals. Here we describe possible mechanisms underlying the effect of iron deficiency, with or without anemia, on childhood development. The high rate of anemia in this age group is a cause for concern. Moreover, anemia should be prevented in the first year of life to avoid long-term negative effects on individual development. / La investigación ha sido financiada por el Instituto Nacional de Salud de Perú. / Revisión por pares

Past research into optimism and pessimism has tended to view these constructs as polar opposites of a fixed personality trait that function in mutually exclusive ways. In the field of child development in particular, this has led to theory-driven work that not only accepts this dichotomy but also uses it to drive and explicate larger issues of resilience and vulnerability. The current thesis challenges the assumptions underpinning this conceptual framework, and, through the use of divergent methodologies, seeks to establish children’s optimism as a dynamic and adaptive process with predictive value during the developmental period. In the first two studies, predictors and correlates of putative dispositional optimism and pessimism in children and adolescents were examined. A significant age-related decline in optimism was found, but importantly a degree of functional independence between optimism and pessimism was also observed. The third study elicited more specific optimistic expectancies using a vignette methodology. This was seen to share some congruence with the earlier measures of dispositional optimism, but the study also elucidated some of the parameters and realism constraining children’s optimism. Again an age-related decline in optimism was demonstrated that was distinct from any associated changes in pessimism. The fourth and final study involved a pilot examination of the dimensionality of the optimism construct, confirming its functional independence from pessimism, and also demonstrating the fluidity and receptivity of children’s optimistic processes from an intervention perspective. From these various studies, it is concluded that optimistic and pessimistic processes in children and adolescents reflect functionally distinct pathways and drive different aspects of vulnerability and well-being. A reconfiguration of the extant theory in this area seems warranted. Based on this conceptual and methodological critique, a preliminary proposal is put forward towards a more substantive approach to the development of optimism and pessimism during childhood and adolescence. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1317136 / Thesis (Ph.D.) -- University of Adelaide, School of Psychology, 2008

This dissertation examines associations among home noise exposure, language skills, and brain structure and function in children spanning multiple developmental stages. To measure home noise exposure, digital audio recordings of the home environment were obtained and used to calculate home noise levels. To examine brain structure in children, Study 1 leveraged magnetic resonance imaging (MRI). To examine brain function in response to speech sounds in toddlers, Study 3 leveraged electroencephalography (EEG) in order to elicit event-related potentials (ERPs) that have been related to language abilities. All studies also incorporated the use of standardized assessments of language to examine children’s developing language abilities and used either parent-report measures of language (Study 2) or direct assessments of children’s language abilities (Studies 1 & 3). Primary hypotheses included that higher home noise exposure would be associated with 1) reduced cortical thickness (Study 1), 2) lower scores on measures of language skills in infancy and childhood (Studies 1, 2, and 3), and reduced neural differentiation of speech sounds (Study 3). Together, these findings shed light on the potential impact of noise exposure on children’s brain and language development. By better understanding how factors in children’s everyday environments might influence neural and cognitive development, we can best inform efforts aimed at optimizing children’s developmental trajectories.

The aim of this study was to develop a Gestalt programme for parents of toddlers to empower them to contribute to the optimal development of their toddlers. Intervention research (Thomas & Rothman) as phase model was used as method for this study. During the first phase the managers or heads of three day-care centres were used to gain access to parents of toddlers. Parents were asked to complete a questionnaire with the objective to explore their attitude towards aspects such as communication with their toddlers, emotions of their toddlers and their disciplinary style. The questionnaire was also used to determine their needs with regard to the education of their toddlers. During the second phase a literature study was undertaken to explore the development of the toddler and the dynamics of the Gestalt approach. The Gestalt approach was used as cornerstone for the programme because of its holistic approach to the interaction between persons and the environment on all levels. This study concludes at Phase 4 by designing a prototype Gestalt programme for parents of toddlers. / Social Work / M. Diac (Play Therapy)

Die kwaliteit van die ouer-kindverhouding het 'n kardinale invloed op die emosionele, sosiale, kognitiewe en konatiewe ontwikkeling van die kind. In hierdie studie is die interaksies tussen die ouer en kind tydens die toepassing van die saamleestegniek bestudeer om te bepaal wat die invloed van die saamleestegniek op die verhouding tussen die ouer en die kind met leesprobeme is. Die studie is vanuit 'n kwalitatiewe benadering voltrek om insig te verkry in die spesifieke aspekte van die saamleestegniek wat die ouer-kindverhouding kan beinvloed. Die moontlikheid word verder ondersoek dat die ouer aspekte vanuit die saamleestegniek kan veralgemeen en daagliks in die ouer-kindverhouding kan toepas om sodoende die verhouding te verbeter. Die finale gevolgtrekking is dat die ouer 'n sleutel-rol vervul tydens die toepassing van die saamleestegniek. Indien die ouer die riglyne van die tegniek kan toepas, sal die verhouding tussen die ouer en die kind met leesprobleme verbeter. / The quality of the parent-child relationship plays an essential role in the sosio­-emotional development of the child. The interaction between parent and child is researched within the context of paired reading, to ascertain whether paired reading influences the relationship between the parent and the child with reading problems. This study is qualitative and gains insight into the unique experiences of the parents and children during paired reading. The researcher aims to identify specific aspects of paired reading that could influence the parent-child relationship. The possibility that certain educational aspects from paired reading can be applied to daily parent-child interaction to improve the relationship, is also researched. The final conclusion is that the parent performs a key role in the application of paired reading: If the parent adheres accurately to the guidelines of the technique, the relationship between the parent and the child with a reading disability will improve. / Psychology of Education / M.

The relationship between maternal sensitivity (MS) and child outcomes has been examined by earlier research. There is some evidence that MS plays a role in shaping temperament development in early childhood. Child temperament outcomes are a significant predictor for functioning in later life. The study is based on 952 mother-infant pairs from the Avon Longitudinal Study of Parents and Children (ALSPAC). MS was observed at 12-months and temperament at 24-months. Linear regression was used to investigate the association between MS and temperament, adjusting for a range of confounders (temperament at 6 months, gender, SES, maternal mental health, maternal preconceptions of her child, parental conflict, gestation and maternal age). Multiple imputation was used to account for attrition. Mother-child interactions rated as “cool/moderate” were associated with more difficult temperament on the dimensions of “approach” (Coef 0.35, CI 0.09, 0.60),“rhythmicity”(Coef 0.43, CI 0.19, 0.68) and “adaptability” (Coef 0.24, CI 0.00, 0.49). The associations remained after adjusting for confounders in the imputed data set. There is evidence that maternal warmth may be influential in the development of child temperament, particularly positive affect, sociability and affect regulation. Further research is needed to replicate these findings.

The majority of children in the UK live in households with two parents, yet most of the academic research on parenting focuses on the relationship between one parent and one child. More often than not, this one parent has been the mother. There is an expectation of father involvement in contemporary parenting, but the literature still tends to emphasise parenting as a one parent-one child interaction, measuring involvement of the father in terms of time spent with his child. The idea of collaboration, or collaborative parenting, drawing on research into coparenting in the US, considers the involvement of both parents with each other, with respect to the child, as an alternative way of conceptualising parental involvement. Collaboration is considered a useful concept, as it goes beyond the idea of parenting as being about time spent directly with the child. Unlike many factors which may predict child outcomes, a lack of collaboration could be addressed at the family level, through counselling or education. The aims of the research were to develop an understanding of the way in which parents work together, looking in particular at how this is affected by social support; whether there are associations between parental collaboration and the availability of time for family and leisure activities, and feelings about the balance between work and home life; whether parents who collaborate are more likely to adhere to expert advice on parenting matters; and whether there are associations with a child’s social, emotional and behavioural development. Emphasis was also placed on the methodology, as it entailed the development of a method for measuring the concept of collaboration, using data that was not designed for the purpose. The research was conducted through a combination of methods, comprising secondary analysis of data from the first four sweeps of the Growing Up in Scotland (GUS) study, and the conduct and analysis of 20 pairs of semi-structured interviews with parents who had previously taken part in this study. A condition of the funding received from the Scottish Government was to make use of the GUS data. The research found social support affected the process of collaboration in a number of ways: by enabling collaboration to take place; by removing the need for collaboration; by increasing the time available to collaborative couples; and by removing the need to plan ahead. Of particular note were the problems that were more likely to occur when couples neither collaborated, nor had support from outside the home. These are the couples who find that work impacts on their family the most. They are also the ones who are least likely to have time away from their children to do something for their own interest, and are the ones who are most likely to find it difficult to access advice. Collaborative couples tended to find more time available for activities with their children, as well as time for themselves. Positive associations were demonstrated between collaboration and a child’s social, emotional and behavioural development, but the strength of the association was not equal in all situations. When the mother was employed full-time, relatively strong associations were evident. When she was not in employment, and a number of other risk factors were present, relatively strong associations could again be seen. However, when the mother worked part-time, there did not appear to be any association between child behavioural development and collaboration. Associations were also demonstrated with the work-life balance of parents. Collaborative fathers professed less of an impact of the family on their work than non-collaborative ones. Similarly, collaborative fathers were less likely to say that long hours impacted on the time they had with their children than non-collaborative fathers, but there was no equivalent association for mothers. The impact of work on family was more likely to be lower for both parents when they acted collaboratively.

The purpose of this study is to describe six-to twelve-year-old children's views of childbirth using words and drawings of children who were present when a baby was born in order to understand children's conceptualization of birth. As background to the study, the accessibility of childbirth to children through time and space was reviewed in the Human Relations Area Files. The information revealed cultural units both allowing and forbidding attendance of children at birth. Interviews and drawings were used to collect data from 14 informants. Audiotape-recordings of the interviews were transcribed, analyzed and organized into meaningful categories, which were validated by six key informants. The categories represented the knowledge used by children to interpret childbirth and included: people who do things at birth, steps in a baby being born, things people do at birth, best parts of being there, worst parts of being there, things that are gross at birth, things that are scary at birth, and things for kids to know about being there. The relationships of the categories were discussed in themes inferred from the data by the researcher. The themes identified were: I never seen it before; the first time you don't know; it might not be scary for you, but it was for me; the more often you see it, the less it bothers you; dads, kids and ladies help; I can't stand to miss it; it's kind of gross for the person who has to watch; and you learn by being there. The themes are discussed in relation to the research questions, health care and concepts that guided the study (childbirth as a sociocultural event, culture of childhood, child's-eye view, and cognitive development). Health professionals, especially nurses, have the opportunity to prepare parents and children for birth, to facilitate family-centered birthing practices and to minimize the strains related to life processes, such as birth and development. Childbirth through children's eyes communicates the birth event as a situational crisis as well as a developmental opportunity.
