Companion Animals and other Factors Affecting Young Children's Development

ABSTRACT

This study focuses on three factors presumed to affect young children's development: their age, the quality of their home environments, and the child-pet relationship. Three sets of analyses are presented: effects associated with pet ownership (pet presence), effects associated with the strength of the child-pet relationship, and the combined effects of age, home environment, and the child-companion animal relationship. This study includes both a parent survey (n = 88) and in-home assessments (n = 44) of the three- to six-year-old children. The analyses support the hypothesis that normal preschool children's intellectual, motor, and social development is associated with the presence of a companion animal and increases with their age, the quality of their home environment, and their relationship with a companion animal. While the children's age and the quality of their home environments were associated with measures of the children's cognitive, motor, and social development, the companion animal effect was limited to the young children's social development including their empathy for other children.     

Developmental Phases of Personality Formation in Childhood (I)

One of the problems that has contributed to a refinement of the "functional procedure of double stimulation" in experiments is the problem of concept formation in children. To form an idea of the significance of this experimental method for the study of children's concepts, it must be viewed against the background of other methods that have been used to deal with the same problem. The psychology of children's concepts not only is of tremendous theoretical interest but also undoubtedly has applied psychological importance since the accumulation of concepts, their nature, and the way they are used are unquestionably correlated with a child's level of intellectual development and are, to some extent, indicators of that level.     

Sibling and environment correlates of children's achievement: Sex group differences

Abstract

Regression surface analysis was used to examine associations between sibling variables and measures of academic achievement and intellectual ability at different levels of social status and family environment variables for girls and boys. The sample was 460 Anglo‐Australian families, each with an 11‐year‐old child. Family environments were defined by parents’ aspirations for their children and parents’ instrumental and affective orientations. Regression models included terms to account for possible linear, interaction, and curvilinear relations between sib size and birth order and measures of word knowledge, word comprehension, mathematics performance, and intellectual ability. The findings indicated that the sibling variables were poor predictors of children's cognitive performance. Typically, sib size and birth order were not related to children's academic performance at different levels of family environment scores.     

Predictors of accurate maternal perception of their preschool child's weight status among Hispanic WIC participants

Childhood obesity is a growing problem in the United States. Parental perception of their children's weight status is a key factor that needs to be considered when developing prevention programs for preschool children. Using a randomly selected sample of participants of Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Los Angeles County, we assessed accuracy of maternal perceptions of their children's weight status by comparing children's weight classification to the mothers' response to the question “Do you consider your child to be overweight, underweight or about right weight for (his) (her) height?” Additionally, we identified possible predictors of accurate maternal perception of their children's weight status by conducting a logistic regression model with child's gender, child's birth weight, maternal age, maternal BMI, maternal education, maternal acculturation level, and maternal language preference as potential predictors. Almost all mothers in the study classified their overweight or obese child as being about the right weight (93.6% and 77.5% of mothers, respectively). Maternal BMI and child's birth weight were the only predictors of maternal perception of their child's weight. Both were negatively associated with accuracy, with higher maternal BMI and higher infant birthweight associated with less accurate maternal perception of child weight. Parents need to be educated on the importance of childhood obesity and how to identify if their children are overweight or obese. If parents fail to recognize that their overweight child is overweight, then it is unlikely that they will recognize that interventions targeting obesity are relevant to their families.     

Drawing a Close to the Use of Human Figure Drawings as a Projective Measure of Intelligence

The practice of using children''s human figure drawings (HFDs) to assess their intellectual ability is pervasive among psychologists and therapists in many countries. Since the first systematic scoring system for HFDs was published in 1926, their continued popularity has led to the development of several revised versions of the test. Most recently, the Draw-A-Person Intellectual Ability Test for children, adolescents, and adults (DAP:IQ) was published. It is the most up-to-date form of HFD test designed to assess intellectual functioning across a wide age range. In the present study, we assessed the validity of the DAP:IQ as a screening measure of intelligence in both children and adults. In Experiment 1, 100 4- to 5-year-old children completed the DAP:IQ and the Wechsler Preschool and Primary Scale of Intelligence-Third Edition. In Experiment 2, 100 adults completed the DAP:IQ and the Wechsler Abbreviated Scale of Intelligence. In both experiments, we found only weak to modest correlations between scores on the DAP:IQ and the Wechsler tests. Furthermore, when we compared individual''s scores on the two tests, the DAP:IQ yielded high false positive and false negative rates when screening for borderline and superior intellectual functioning. Based on these findings, and based on the lack of validity of previous HFD tests, we conclude that practitioners should not rely on HFD tests as a projective measure of intelligence.     

The Development of Purpose During Adolescence

While there has been much research on adults' abilities to detect deception, there have been very few studies examining both children's and adults' abilities to detect children's real, spontaneous lies. The present study asked both children and adults to make judgments of children's true and false reports. Participants (N = 156) were shown videotaped sessions of children who were either spontaneously lying or telling the truth. Results indicate that both children's and adults' accuracy for detecting children's true statements was below chance. However, older children were significantly better at detecting lies than both younger children and adults.     

扁桃体部分切除术最新进展

扁桃体切除术是耳鼻咽喉科最常见的手术之一,临床上治疗由于扁桃体肥大所致的儿童睡眠阻塞性呼吸暂停综合征,最常用的手术方式为双侧扁桃体切除术。扁桃体在儿童生长发育过程中具有重要的免疫功能,完全切除扁桃体对儿童的免疫功能具有一定的影响。且扁桃体全部切除术后常见一些并发症如出血及疼痛,这使得许多学者提出了扁桃体部分切除术。扁桃体部分切除术较扁桃体全部切除术相比,手术时间短、术后并发症少,在缓解儿童阻塞症状的同时,保留了一部分扁桃体,对于免疫功能也有一定的保留。本文将从扁桃体部分切除术治疗儿童睡眠呼吸暂停综合征的临床疗效以及术后出血、术后疼痛方面作一综述,为扁桃体部分切除术应用于临床提供合理依据。     

Assessment of objectively measured physical activity levels in individuals with intellectual disabilities with and without Down's syndrome

Objective

To investigate, using accelerometers, the levels of physical activity being undertaken by individuals with intellectual disabilities with and without Down''s syndrome.

Methods

One hundred and fifty two individuals with intellectual disabilities aged 12–70 years from East and South-East England. Physical activity levels in counts per minute (counts/min), steps per day (steps/day), and minutes of sedentary, light, moderate, vigorous, and moderate to vigorous physical activity (MVPA) measured with a uni-axial accelerometer (Actigraph GT1M) for seven days.

Results

No individuals with intellectual disabilities met current physical activity recommendations. Males were more active than females. There was a trend for physical activity to decline and sedentary behaviour to increase with age, and for those with more severe levels of intellectual disability to be more sedentary and less physically active, however any relationship was not significant when adjusted for confounding variables. Participants with Down''s syndrome engaged in significantly less physical activity than those with intellectual disabilities without Down''s syndrome and levels of activity declined significantly with age.

Conclusions

Individuals with intellectual disabilities, especially those with Down''s syndrome may be at risk of developing diseases associated with physical inactivity. There is a need for well-designed, accessible, preventive health promotion strategies and interventions designed to raise the levels of physical activity for individuals with intellectual disabilities. We propose that there are physiological reasons why individuals with Down''s syndrome have particularly low levels of physical activity that also decline markedly with age.     

Commentary: Impact of Father Involvement on Children's Developmental Trajectories: New Findings Panel for the National Fatherhood Forum

Numerous scholars have called for increased attention to, and sophistication in, understanding the family roles of fathers and their influence on children's development. The articles in this section provide notable moves forward in several arenas, focusing on traditionally understudied populations of fathers, employing a variety of data collection methodologies, and assessing leading theoretical models in the field. In this commentary, the authors review these strengths and delineate important next steps for fathering research. They call for increased research in three arenas: (1) attention to fathers' uniqueness through detailed study of the similarities and differences in mothers' and fathers' behaviors and effects on children; (2) a focus on generalizability, developing models and methods that can be applied across diverse samples of fathers; and (3) more rigorous development and assessment of models delineating fathers' influence on children's development, attending to both promotive and harmful effects of fathering.     

Is Parental Control over Children's Eating Associated with Childhood Obesity? Results from a Population‐Based Sample of Third Graders

Objective: Identifying parental behaviors that influence childhood obesity is critical for the development of effective prevention and treatment programs. Findings from a prior laboratory study suggest that parents who impose control over their children's eating may interfere with their children's ability to regulate intake, potentially resulting in overweight. These findings have been widely endorsed; however, the direct relationship between parental control of children's intake and their children's degree of overweight has not been shown in a generalized sample. Research Methods and Procedures: This study surveyed 792 third‐grade children with diverse ethnic and socioeconomic backgrounds from 13 public elementary schools. Parental control over children's intake was assessed through telephone interviews using a state‐of‐the‐art instrument, and children were measured for height, weight, and triceps skinfold thickness. Results: Counter to the hypothesis, parental control over children's intake was inversely associated with overweight in girls, as measured by body mass index, r = ?0.12, p < 0.05, and triceps skinfolds, r = ?0.11, p < 0.05. This weak relationship became only marginally significant when controlling for parents’ perceptions of their own weight, level of household education, and children's age. No relationship between parental control of children's intake and their children's degree of overweight was found in boys. Discussion: Previous observations of the influence of parental control over children's intake in middle‐class white families did not generalize to 8‐ to 9‐year‐olds in families with diverse socioeconomic and ethnic backgrounds. The present findings reveal a more complex relationship between parental behaviors and children's weight status.     

Parental attachment and children's memory for attachment-relevant stories

Despite evidence that parents’ attachment is associated with children's memory, less is known about the mechanisms underlying this association or the contexts in which the association is most meaningful. The present study examined whether parents’ attachment predicted children's memory for stories regarding attachment-related topics, whether the cohesiveness of children's stories mediated the association between attachment and memory, and whether the association varied by interview support at retrieval. Five- to six-year-olds completed attachment-relevant stories while parents provided information about their romantic attachment. Children's stories were coded for cohesiveness. A week later, children's memory for their stories was tested by either a supportive or nonsupportive interviewer. When the interview was nonsupportive, greater parental avoidance was associated with poorer memory, whereas when the interview was supportive, greater parental avoidance was associated with fewer errors. Findings provide insight into the context under which parents’ attachment is most influential in shaping children's memory.     

Attitudes toward homosexuals: A rejoinder

The differences in the positions adopted by Gallup and myself are highlighted: the developmental process underlying the origin of homosexuality is crucial, because Gallup's reason for parents reacting with hostility to homosexuals is that they will affect their children's sexual orientation. My alternative, a two-process imprinting model, involves a different developmental process, the implications of which are that cross-gender behavior in childhood, rather than seduction by adults, is important for developing homosexual orientation. Criticisms of my alternative explanation of Gallup's findings in terms of xenophobia are also addressed, but it is emphasized that Gallup's hypothesis ultimately relies on the accuracy of his seduction theory of homosexual orientation.     

Individual differences in children's innovative problem-solving are not predicted by divergent thinking or executive functions

Recent studies of children''s tool innovation have revealed that there is variation in children''s success in middle-childhood. In two individual differences studies, we sought to identify personal characteristics that might predict success on an innovation task. In Study 1, we found that although measures of divergent thinking were related to each other they did not predict innovation success. In Study 2, we measured executive functioning including: inhibition, working memory, attentional flexibility and ill-structured problem-solving. None of these measures predicted innovation, but, innovation was predicted by children''s performance on a receptive vocabulary scale that may function as a proxy for general intelligence. We did not find evidence that children''s innovation was predicted by specific personal characteristics.     

Neural Activity during Natural Viewing of Sesame Street Statistically Predicts Test Scores in Early Childhood

It is not currently possible to measure the real-world thought process that a child has while observing an actual school lesson. However, if it could be done, children''s neural processes would presumably be predictive of what they know. Such neural measures would shed new light on children''s real-world thought. Toward that goal, this study examines neural processes that are evoked naturalistically, during educational television viewing. Children and adults all watched the same Sesame Street video during functional magnetic resonance imaging (fMRI). Whole-brain intersubject correlations between the neural timeseries from each child and a group of adults were used to derive maps of “neural maturity” for children. Neural maturity in the intraparietal sulcus (IPS), a region with a known role in basic numerical cognition, predicted children''s formal mathematics abilities. In contrast, neural maturity in Broca''s area correlated with children''s verbal abilities, consistent with prior language research. Our data show that children''s neural responses while watching complex real-world stimuli predict their cognitive abilities in a content-specific manner. This more ecologically natural paradigm, combined with the novel measure of “neural maturity,” provides a new method for studying real-world mathematics development in the brain.     

Children's ideas of animals' internal structures

Children's understanding about animal internal structure can be affected by several factors which are poorly understoodby teachers. We conducted a large sample study (n=702) of children aged 6–16 years (Grades 1-9) examining children's responses to animals of various size, species and dimensions (2D and 3D objects), and exploring factors which might affect the development of their knowledge. Each child made a drawing of what they thought was inside a specimen animal. We found that using 2D representations of an animal negatively affected the content of children drawings.The effect of animalsize was shown only in children's understanding of skeletons, but not organ systems. The effect of animal species showedclear significant effect of children's ideas on both organ systems and skeleton. Investigation showed that parents' education level, children's experiences with animal-rearing and age significantly affected their scores from organ system. Surprisingly, school books were most frequently cited as sources of children's knowledge rather than their own experience, or information from the internet, encyclopaedias, television or parents.     

Identifying the intergenerational effects of the 1959–1961 Chinese Great Leap Forward Famine on infant mortality

Using the 1959–1961 Chinese Great Leap Forward Famine as a natural experiment, this study examines the relationship between mothers’ prenatal exposure to acute malnutrition and their children's infant mortality risk. According to the results, the effect of mothers’ prenatal famine exposure status on children's infant mortality risk depends on the level of famine severity. In regions of low famine severity, mothers’ prenatal famine exposure significantly reduces children's infant mortality, whereas in regions of high famine severity, such prenatal exposure increases children's infant mortality although the effect is not statistically significant. Such a curvilinear relationship between mothers’ prenatal malnutrition status and their children's infant mortality risk is more complicated than the linear relationship predicted by the original fetal origins hypothesis but is consistent with the more recent developmental origins of health and disease theory.     

Weaving carpets, weaving lives: Childhood and ethnicity in downtown Kathmandu

In the developing metropolis public perceptions about caste and ethnicity are influenced by historical trends in decisions about occupations; but what does this mean for children whose families decide they work? In Kathmandu's carpet industry, a large percentage of workers are Tamang, an ethnic group who represent a small percentage of the country's population. Organisations working with Tamang child labourers have predominantly used quantitative research data to construct their intervention strategies. This has left many factors unexamined. This paper discusses qualitative and quantitative research data generated by a team of Nepali practitioners striving to address child labour issues. The purpose of their study was to examine the social and cultural factors influencing child migration and the quality of life for children in the carpet industry. The methodology included participatory indicators of children's social, economic, physical and psychological well-being. The paper will draw on children's perspectives to highlight the role of ethnicity in opportunity and exploitation.     

Parents' Socializing Behavior and Children's Participation in Math,Science, and Computer Out-of-School Activities

This study examined associations between multiple parental behaviors and children's participation in out-of-school math, science, and computer activities for children in 2nd (n = 125), 3rd (n = 123), and 5th grade (n = 200). Mothers and fathers reported how often they encouraged their children's activities, participated in activities with their child, provided activity-related materials, and participated in activities themselves, as well as how often their children participated in activities. The youth described how often they participated in math, science, and computer activities. Results indicate that parents' behavior is a strong, positive predictor of children's participation. Although there were significant mean level gender differences, relations between parents' behavior and children's participation were similar for boys and girls.     

The extended relationship between child cardiovascular risks and academic performance measures

Objective: To examine the relationship between children's overweight status and other cardiovascular risk fitness factors and academic performance among fifth‐grade students. Research Methods and Procedures: Using a sample of 968 fifth‐grade students (50.7% boys; mean age = 10.6 years), children's cardiovascular risks (BMI, blood pressure, acanthosis nigricans) and fitness measures were compared with their mean group performance scores across four subscales (mathematics, reading/language arts, science, and social studies) of a statewide standardized academic performance test. Results: Of this sample, 39% were either at risk for being overweight or were already overweight; slightly over one half were of normal weight. Initial findings revealed a significant relationship between children's weight category and their reading/language arts, mathematics, and science test scores even after controlling for a proxy of socioeconomic status. When additional cardiovascular risk and fitness measures were included in the model, however, children's BMI status had no association. Instead, a composite fitness index, children's blood pressure, sex, and proxy of socioeconomic status were significantly associated with children's academic test scores. Discussion: This study expanded our understanding of the connection between children's overweight risks and academic performance by examining the impact of other cardiovascular risk factors such as high blood pressure and measures of fitness. These findings support the development and implementation of childhood cardiovascular risk surveillance programs that evaluate not only children's overweight risks but also their fitness, risk for type 2 diabetes, and/or high blood pressure by showing a relationship between some of these risks and children's academic test performance.
