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.     

Guest Editorial: Bildung-Psychology: The Substance and Structure of an Emerging Discipline

The present study examined (1) the ways investigative interviewers in forensic settings prepared children for substantive questioning, and (2) whether the techniques used and the amount of time spent in the pre-substantive phase were related to children's informativeness. Accuracy of the children's statements was not assessed. The sample included investigative interviews of a small sample of 75 alleged victims of sexual abuse in Malaysia, aged 5 to 15 years. Explanations of the conversational rules, purpose of the interview, and the children's roles as informants appeared to help the youngest children to be informative. The results also revealed possible limits to the potential benefits of rapport-building and suggest that interviewers should monitor the amount of time they spend preparing children for substantive questioning. Implications for addressing the limitations of the present research and directions for future research are discussed.     

Animal-Assisted Interventions in Children's Hospitals: A Critical Review of the Literature

There is a perception in the scientific and general communities that hospitalized children benefit from visits by animals. Animal-assisted interventions (AAI), including animal-assisted therapy and animal-assisted activities, usually involving dogs, are thus employed in pediatric hospitals. However, the actual prevalence of AAI in children's hospitals has been poorly documented in the literature. Furthermore, the evidence base for claims that children in hospital benefit from AAI is limited. There are nine existing research studies in the area, all with methodological challenges that make conclusive statements in either direction about the efficacy of AAI difficult. In this critical review we consider methodological considerations pertinent to evaluations of AAI interventions for hospitalized children. These include: definitions and terminology; cultural attitudes; children's receptivity to animals, including phobia, type of illness and health status of the child, familiar as opposed to unknown animals, and age of the child; animal welfare; zoonoses and allergies; and hospital staff attitudes toward AAI. We highlight the many difficulties involved in conducting research on AAI in pediatric settings. Given the limited information around AAI for hospitalized children, including the risks and benefits and the limitations of existing studies, future research is required. This should take into account the methodological considerations discussed in this review, so that our knowledge base can be enhanced and if and where appropriate, such interventions be implemented and rigorously evaluated.     

Bilingualism Accentuates Children's Conversational Understanding

Background

Although bilingualism is prevalent throughout the world, little is known about the extent to which it influences children''s conversational understanding. Our investigation involved children aged 3–6 years exposed to one or more of four major languages: English, German, Italian, and Japanese. In two experiments, we examined the children''s ability to identify responses to questions as violations of conversational maxims (to be informative and avoid redundancy, to speak the truth, be relevant, and be polite).

Principal Findings

In Experiment 1, with increasing age, children showed greater sensitivity to maxim violations. Children in Italy who were bilingual in German and Italian (with German as the dominant language L1) significantly outperformed Italian monolinguals. In Experiment 2, children in England who were bilingual in English and Japanese (with English as L1) significantly outperformed Japanese monolinguals in Japan with vocabulary age partialled out.

Conclusions

As the monolingual and bilingual groups had a similar family SES background (Experiment 1) and similar family cultural identity (Experiment 2), these results point to a specific role for early bilingualism in accentuating children''s developing ability to appreciate effective communicative responses.     

Facilitating the Communicative Competence of the Child Witness

Efforts to elicit reliable testimony from children are frustrated by developmental limitations on children's communicative competence. This study examines (a) how children cope when adults ask incomprehensible questions, and (b) whether interview perfonnance can be enhanced by facilitating children's comprehension monitoring and response strategies. One hundred and eighty children, half 6 and half 8-years-olds, were assigned randomly within age group to 1 of 3 treatment conditions (training, instructions, control) and I of 2 interviewer conditions (familiar, unfamiliar). Children's memories of a previously staged event were tested with interview questions varying in comprehensibility. Results suggest that when confronted with difficult-to-comprehend questions regarding easily recalled information, children in the control group tried to answer anyway but were as likely to respond incorrectly as correctly. In contrast, when children were instructed to verbalize their lack of comprehension, and given a rationale for doing so, they performed significantly better than the control group. Moreover, when children received instructions and prepared for the interview with practice detecting and coping with noncomprehension, the training group demonstrated marked improvements in interview performance compared with the other 2 groups. Results demonstrate that although children's limited communication skills present a barrier to reliable testimony, it is one that might be minimized by instructions or preparation of child witnesses.     

Pretrial preparations can improve a physician's value as an expert witness.

Many physicians appear in court as expert witnesses, but the quality of their testimony varies considerably, says a Nova Scotia judge. Pretrial preparation will improve the quality of a physician''s testimony, reduce stress and save time, says Judge Timothy Daley, who provides some suggestions about how to prepare to be an expert witness and what to expect in the courtroom.     

Two Randomized Trials Provide No Consistent Evidence for Nonmusical Cognitive Benefits of Brief Preschool Music Enrichment

Young children regularly engage in musical activities, but the effects of early music education on children''s cognitive development are unknown. While some studies have found associations between musical training in childhood and later nonmusical cognitive outcomes, few randomized controlled trials (RCTs) have been employed to assess causal effects of music lessons on child cognition and no clear pattern of results has emerged. We conducted two RCTs with preschool children investigating the cognitive effects of a brief series of music classes, as compared to a similar but non-musical form of arts instruction (visual arts classes, Experiment 1) or to a no-treatment control (Experiment 2). Consistent with typical preschool arts enrichment programs, parents attended classes with their children, participating in a variety of developmentally appropriate arts activities. After six weeks of class, we assessed children''s skills in four distinct cognitive areas in which older arts-trained students have been reported to excel: spatial-navigational reasoning, visual form analysis, numerical discrimination, and receptive vocabulary. We initially found that children from the music class showed greater spatial-navigational ability than did children from the visual arts class, while children from the visual arts class showed greater visual form analysis ability than children from the music class (Experiment 1). However, a partial replication attempt comparing music training to a no-treatment control failed to confirm these findings (Experiment 2), and the combined results of the two experiments were negative: overall, children provided with music classes performed no better than those with visual arts or no classes on any assessment. Our findings underscore the need for replication in RCTs, and suggest caution in interpreting the positive findings from past studies of cognitive effects of music instruction.     

Early prosociality is conditional on opportunity cost and familiarity with the target

Developmental research in the past decade has painted the picture of a gregarious child ready to engage in a range of prosocial behavior, but less is known about the situational factors that moderate this behavior. The present study investigated the effects of cost and familiarity on children's readiness to help the victim of a moral transgression. Opportunity cost was operationalized as the time and effort expended on providing help, that could otherwise be used to earn a reward from a productive task. Familiarity varied as a function of whether there was prior contact between the child and victim. Five- and six-year-olds in Singapore (N = 120) witnessed an adult transgressor destroy the victim's tower of blocks, responded to the victim's pleas for help in rebuilding her tower, and shared resources with both actresses. Contrary to our initial predictions, children helped a familiar victim less when cost was high as opposed to low, but helped an unfamiliar victim equally regardless of cost. Additionally, helping rates were low (30–60%) except in the least prohibitive condition (> 80%; Low-Cost, Familiar Victim), stemming from a combination of not having a productive task to occupy one's time and energy, and simultaneously a familiar target which increased one's intrinsic motivation to help. The conditional limits imposed on children's decision to help thus appear to be, “I'll help, if I know you and have nothing better to do!” In terms of resource sharing, children behaved selfishly toward both the victim and transgressor regardless of their familiarity with the victim. Altogether, our findings suggest that children consider self-interest when deciding whether to help and share with others.     

Sociodemographic and motivational characteristics of parents who volunteer their children for clinical research: a controlled study.

OBJECTIVE--To determine the sociodemographic and motivational characteristics of parents who volunteer their children for clinical research. DESIGN--A questionnaire was administered to parents who volunteered their children for a randomised, double blind, placebo controlled trial of a drug to treat asthma and to a control group of parents whose children were eligible for the trial but had refused the invitation. SETTING--A children''s hospital in Australia. SUBJECTS--68 Parents who had volunteered their children and 42 who had not; a response rate of 94% and 70%, respectively. MAIN OUTCOME MEASURES--Responses of parents to questionnaire designed to assess their perceptions, attitudes, and health seeking behaviour as well as sociodemographic data. RESULTS--Volunteering parents were less well educated with only 15% (10/68) of mothers and 16% (11/68) and of fathers having had a tertiary or university education compared with 26% (11/42) of mothers and 45% (19/42) in the non-volunteering group. Fewer volunteering parents had professional or administrative jobs than did non-volunteering parents (mothers 6% (4/68); fathers 9% (6/68) v mothers 14% (6/42); fathers 31% (13/42)). Volunteering parents had less social support, and they displayed greater health seeking behaviour and consumed more habit forming substances. They were motivated by a desire to help others and to contribute to medical research, but they were also searching for more information and better ways to help their own children. CONCLUSION--Parents who volunteer their children for medical research are significantly more socially disadvantaged and emotionally vulnerable.     

Does benefit justify research with children?

The inclusion of children in research gives rise to a difficult ethical question: What justifies children's research participation and exposure to research risks when they cannot provide informed consent? This question arises out of the tension between the moral requirement to obtain a subject's informed consent for research participation, on the one hand, and the limited capacity of most children to provide informed consent, on the other. Most agree that children's participation in clinical research can be justified. But the ethical justification for exposing children to research risks in the absence of consent remains unclear. One prevalent group of arguments aims to justify children's risk exposure by appealing to the concept of benefit. I call these ‘benefit arguments’. Prominent versions of this argument defend the idea that broadening our understanding of the notion of benefit to include non‐medical benefits (such as the benefit of a moral education) helps to justify children's research participation. I argue that existing benefit arguments are not persuasive and raise problems with the strategy of appealing to broader notions of benefit to justify children's exposure to research risk.     

Watch out! How a fearful face adds credibility to warnings of danger

People display facial expressions of fear to communicate danger to others and sometimes to exaggerate danger to manipulate an audience. Here we test whether fear expressions add credibility to a speaker's warnings of danger. Participants played an incentivized lie detection game in which they guess whether a confederate partner is lying or telling the truth. Participants viewed a video of their partner's message, after reading that there was a good chance (75%) their partner was instructed to lie. We manipulated across conditions whether the partner stated the message with a neutral or fearful expression. Experiment 1 finds that participants were more likely to believe the speaker's warning of danger when it was conveyed with a fear expression compared to a neutral expression. Experiment 2 finds that when a speaker instead claimed that a danger was absent, a fearful expression no longer added credibility to their message. These findings provide evidence that fear expressions add credibility to statements of danger, specifically, rather than any claim.     

Nephroblastoma: treatment during 1970-3 and the effect on survival of inclusion in the first MRC trial.

In 1970-3 313 children were diagnosed as having nephroblastoma in Great Britain. From the start of the first Medical Research Council nephroblastoma study in October 1970 until the end of 1973, 98 children (57% of all eligible children) were included in the trial. Of the 313 children, 288 (92%) had a nephrectomy, 248 (79%) received a course of radiotherapy, and 267 (85%) were given at least four days'' chemotherapy. The three-year survival rate was 58%; the rate among children in the trial (77%) was significantly better than that among children who were eligible for the trial but not included (58%). Children who had nephrectomies at specialised children''s and teaching hospitals had a higher survival rate than those treated elsewhere. All children with nephroblastoma should be treated according to well-defined protocols which take into account the age of the child and the stage of the tumour and include a full course of maintenance chemotherapy.     

Influence of Body Composition on the Accuracy of Reported Energy Intake in Children

Objective: Mis‐reporting dietary intake is a substantial barrier to understanding the role of dietary behavior in disease. Work with adults indicates that heavier individuals under‐report dietary intake and that under‐reporting may be macronutrient‐specific. Whether weight status and macronutrient intake influence the accuracy of dietary reports among children, however, is less clear. This research evaluated children's dietary reporting accuracy as a function of their relative weight, body composition, and macronutrient intake. Research Methods and Procedures: Participants included 146 4‐ to 11‐year‐old children. Reported energy intake was determined by interviewing children in the presence of parents, using three multiple pass, 24‐hour recalls. Children were classified as having had an under‐reported, accurately reported, or over‐reported dietary intake relative to total energy expenditure, as measured by doubly labeled water. Reporting accuracy was examined as a function of children's body weight, body composition (using dual energy x‐ray absorptiometry), and macronutrient intake. Results: Average reported intake was, on average, 14% greater than children's estimated expenditure (p < 0.01). Reporting accuracy varied as a function of children's relative weight and body composition; under‐reporting tended to occur among heavier children, having the highest body fat content (p < 0.0001) and relative weight (p < 0.0001). Discussion: These findings suggest that weight status influences the accuracy of dietary reports made by children and their parents. More research is needed to address possible psychological and social factors that introduce bias in reporting children's dietary data.     

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.     

Away-from-home food intake and risk for obesity: examining the influence of context

Objective: This study examined sociodemographic and cultural determinants of away‐from‐home food consumption in two contexts and the influence of frequency of away‐from‐home food consumption on children's dietary intake and parent and child weight status. Methods and Procedures: Parents of children (N = 708) in grades K‐2 were recruited from 13 elementary schools in Southern California. Parents were asked through a questionnaire the frequency with which they eat meals away from home and the restaurant they frequented most often. The height and weight of the parents and their children were measured to calculate BMI. Results: Consuming foods at least once a week from relatives/neighbors/friends (RNF) homes was associated with children's dietary intake and children's risk for obesity. For example, children of parents with weekly or greater RNF food consumption drank more sugar‐sweetened beverages. Parents of families who ate at restaurants at least weekly reported that their children consumed more sugar‐sweetened beverages, more sweet/savory snacks, and less water compared with families who did not frequent restaurants this often. The type of restaurant visited did not affect diet intake or obesity. More acculturated families exhibited less healthy dietary behaviors than less acculturated families. Discussion: Restaurants remain an important setting for preventing child and adult obesity, but other settings outside the home need to be considered in future intervention research. This may especially involve eating in the homes of RNF.

The Children's Treatment of Animals Questionnaire: A Rasch Analysis

ABSTRACT

The study of human–animal interactions is limited by a paucity of empirically validated measures of humane treatment of companion animals. The current study reports findings from a psychometric analysis of the Children's treatment of animals Questionnaire (CTAQ; thompson and Gullone 2003), an instrument that assesses children's humane interactions with nonhuman animals. Specifically, the current study extends what is known about the psychometric properties of the CTAQ by using traditional and item response theory analyses. The CTAQ was administered to a sample of 217 school-age children whose mothers were currently receiving residential or non-residential domestic violence services. Item-analysis, exploratory factor analysis, and parallel analysis were conducted to replicate previous psychometric evaluations of the CTAQ. Rasch analysis of the CTAQ was also conducted to provide a stringent test of unidimensionality and to identify potential invariance in item functioning across various demographic variables. The CTAQ showed adequate fit to the Rasch model; one modification, removal of item 5, was required. A Rasch principal components analysis of residuals indicated a single latent dimension among the remaining 12 items. Scale use was appropriate; Rasch-andrich thresholds increased with category values and no disordering of categories was evident. Examination of item-person maps indicated the sample was also well-targeted. Notably, evidence of differential item function was found across Spanish and English translations. Overall, findings indicate that the CTAQ is an appropriate unidimensional measure of children's humane treatment of animals. The measure is particularly well-suited for children ages 7 to 12 years who are at risk for exposure to and perpetration of animal cruelty. We recommend use of a 12-item version of the CTAQ to enhance the utility of the total score as a latent measure of children's humane treatment of companion animals.
