Gender and sexuality in young children's perspectives of AIDS

Abstract

Responses to AIDS have often neglected children. Drawing on a qualitative study of young children aged 7–9 years, this paper draws attention to their understandings of HIV and AIDS. It is argued that young children are able to give meaning to the disease in ways that link to their social contexts, where gender inequalities and sexual violence are common. Sexuality is a key dimension through which they express knowledge of the disease. Young children do know the links between sex and AIDS, and connect vulnerability to the disease in gendered ways. To address the missing voices of young children requires coordinated efforts, requiring systemic responses which support teachers in initiatives to address taboo subjects like sexuality, as well as the pervasive poverty in which the children in our study are located.     

Patterns in children's ability to recall explicit,implicit and metaphorical information

The purpose of this study was to examine the effects of grade level and recall task type on children's memory for explicit, implicit and metaphorical information following reading. Forty second and 40 fifth grade subjects balanced as to gender read four prose passages and were randomly assigned to cued and free recall conditions. A MANOVA produced significant main effects for grade level and task type on each of three dependent variables; EXPLICIT, IMPLICIT and METAPHOR recall measures. As predicted, fifth graders fared better than second graders and the cued condition exceeded free recall. Of greater significance was the finding that second graders were able to engage in metaphorical reasoning when the task was appropriately structured. The results suggest that providing externally generated, structured probes can greatly enhance children's reading recall at both grade levels and can enable children to demonstrate metaphorical comprehension prior to the age at which it spontaneously appears. In addition, significantly different patterns of recalled information were found within the two task conditions, patterns that remained stable across age groups.     

Individual differences in children's ability to profit from picture adjunct aids

A paired-associate memory task with pictures and words as items was used to categorize fourth graders into four learner types: HH, high picture-high word; HL, high picture-low word; LH, low picture-high word; LL, low picture-low word. Some children in each classification read prose passages with picture adjunct aids; other children read the passages without adjunct aids. Although free recall for the prose passage yielded inconclusive data, a constructed response test for facts in the prose passages revealed significant Aptitude × Treatment interactions, such that poor paired-associate learners (i.e., LLs) profited more than did good paired-associate learners (i.e., HHs) from picture aids on the prose task. The children's standardized reading scores were positively related to memory performance, but good and poor readers did not differ in their ability to profit from picture aids. It was suggested that less-strategic learners, such as those who perform poorly on paired-associate tasks, are more likely to be helped by externally provided mediational aids, while more-strategic learners are more likely to be helped by instructions to generate their own mediational aids.     

Young children's beliefs about the relationship between gender and aggressive behavior

Young children's beliefs about the relationship between gender and aggression were examined across 3 studies (N=121). In Study 1, preschoolers (ages 3 to 5) described relational aggression as the most common form of aggression among girls and physical aggression as the most common form among boys. In Study 2, preschoolers and a comparison group of 7- to 8-year-olds were likely to infer that relationally aggressive characters are female and physically aggressive characters are male. Study 3 revealed that preschoolers show systematic memory distortions when recalling stories that conflict with these gender schemas. These findings suggest that even before children reach school age, they have organized patterns of beliefs about gender that affect the way they process social information.     

Young children's number sense in Finland,Hong Kong and Singapore

This study examines young children's number sense in subjects from Finland (n=254), Hong Kong (n=246), and Singapore (n=130). Chinese, English and Finnish versions of the Early Numeracy Test (ENT; Van Luit et al., 1994) were used. Two highly correlated aspects of number sense were measured, one reflecting children's abilities to organize and compare quantities (i.e. relational skills), and the other pertaining to their ability to operate with number-word sequence (i.e. counting skills). The results showed significant age-related gain on the relational and counting scales. No gender or language differences were found. The children in Hong Kong and Singapore outperformed those in Finland in relational and counting tasks starting at the age of four years. The children in Singapore also had better relational and counting skills than those in Hong Kong. Differences in teaching were assumed to explain the findings.     

Young children's references to temporal attributes of allegedly experienced events in the course of forensic interviews

Developmental differences in references to temporal attributes of allegedly experienced events were examined in 250 forensic interviews of 4- to 10-year-old alleged victims of sexual abuse. Children's ages, the specific temporal attributes referenced, and the types of memory tapped by the interviewers' questions significantly affected the quantity and quality of temporal references produced. The findings documented age-related increases in 4- to 10-year-olds' references to temporal attributes, using the appropriate relational terminology, both spontaneously and in response to temporal requests. More references to temporal attributes were elicited from recall than from recognition memory, highlighting spontaneous reporting capabilities. Implications for theories concerning the developing understanding of temporal concepts and for the design of effective, age-appropriate, forensic interview techniques are discussed.     

Young children's learning and transfer of biological information from picture books to real animals

Preschool children (N = 104) read a book that described and illustrated color camouflage in animals (frogs and lizards). Children were then asked to indicate and explain which of 2 novel animals would be more likely to fall prey to a predatory bird. In Experiment 1, 3- and 4-year-olds were tested with pictures depicting animals in camouflage and noncamouflage settings; in Experiment 2, 4-year-olds were tested with real animals. The results show that by 4 years of age, children can learn new biological facts from a picture book. Of particular importance, transfer from books to real animals was found. These findings point to the importance that early book exposure can play in framing and increasing children's knowledge about the world.

Young children's inductions from natural kinds: the role of categories and appearances

Recent analyses of natural kind terms (e.g., dog, gold) suggest that people expect members of a kind to share unforeseen properties. The present study investigated the development of this expectation by studying children's inductive inferences. On each of a series of problems, 3- and 4-year-old children were taught a new fact about an object and then were asked whether it would generalize to: an object that looked like the original, that had the same label as the original, that looked like the original and had the same label, or that differed from the original in both respects. The results indicate that 3- and 4-year-olds drew more inferences based on category membership than on perceptual appearances, when both were available. Furthermore, children often based their inferences on category membership even when no label was provided. Thus even 3-year-olds assumed that natural kind categories include more than superficial features.

Young children's play qualities in same-, other-, and mixed-sex peer groups

This research examined how children's play varied as a function of the sex of the child, the sex of the play partner, and whether they played in dyads or groups. Children (mean age = 52 months) were observed during their free play. Data revealed that boys' same-sex play was more active-forceful, further from adults, and more stereotyped than girls' play, and that this pattern was generally exaggerated in groups versus dyads. Children rarely played only with children of the other sex (other-sex peers), but about one fourth of their interactions involved children of both sexes (mixed-sex peers). Compared with same- or dyadic other-sex play, mixed-sex play was more likely to occur near adults, and was intermediate in active-forceful and stereotyped activity choices. Findings confirmed that children's experiences in peer groups vary depending on the sex of the child and sex of play partners.     

Children's understanding of representational change and its relation to the understanding of false belief and the appearance-reality distinction

This research concerns the development of children's understanding of representational change and its relation to other cognitive developments. Children were shown deceptive objects, and the true nature of the objects was then revealed. Children were then asked what they thought the object was when they first saw it, testing their understanding of representational change; what another child would think the object was, testing their understanding of false belief; and what the object looked like and really was, testing their understanding of the appearance-reality distinction. Most 3-year-olds answered the representational change question incorrectly. Most 5-year-olds did not make this error. Children's performance on the representational change question was poorer than their performance on the false-belief question. There were correlations between performance on all 3 tasks. Apparently children begin to be able to consider alternative representations of the same object at about age 4.

Wallace and Grornit: the Curse of the Were-Rabbit -a study of modality, address, reading and response in contemporary children's film

This study examines the process of making meaning from a media text, exploring Curse of the Were‐Rabbit as a successful example of contemporary film‐making for children. It springs from working with a group of Year 8 students with literacy difficulties who made meaning from film with proficiency, skill and subtlety whilst struggling with the written word; it seeks to unpack the complexity of the process and hence reassess the value of media texts within the curriculum.     

Reporting possible sexual abuse: a qualitative study on children's perspectives and the context for disclosure

OBJECTIVE: The present study investigated the context in which children were able to report their child sexual abuse experiences and the children's views as to what made it difficult to talk about abuse and what helped them in the disclosing process. The aim was to study disclosures as they were occurring in their natural settings. METHOD: Data were obtained from therapeutic sessions and follow-up interviews from 20 families with 22 children. These children had said something that made their caregivers concerned about ongoing child sexual abuse. Qualitative analysis was conducted to capture the children's and caregiver's perspectives of the disclosure process. RESULTS: The children felt it was difficult to find situations containing enough privacy and prompts that they could share their experiences. They also were sensitive to others reactions, and whether their disclosures would be misinterpreted. When the children did disclose they did it in situations where the theme of child sexual abuse was in some form addressed or activated. The results indicate that disclosure is a fundamentally dialogical process that becomes less difficult if the children perceive that there is an opportunity to talk, and a purpose for speaking, and a connection has been established to what they are talking about. CONCLUSIONS: It is difficult for children to initiate a conversation about something secret, confusing and distressful, and where there are few conversational routines in a family for talking about such themes. Children also are sensitive to the needs of their caregivers and fear consequences for their family and offender. Children need a supportive structure or scaffold in order to reveal their experiences of child sexual abuse.     

Executive processes in appearance-reality tasks: the role of inhibition of attention and symbolic representation

Two studies addressed the role of representation ability and control of attention on solutions to an appearance-reality task based on two types of objects, real and representational. In Study 1, 67 preschool children (3-, 4-, and 5-year-olds) solved appearance-reality problems and executive processing tasks. There was an interaction between object type (real vs. representational) and question type (appearance vs. reality) on problem difficulty. In addition, representational ability predicted performance on appearance questions and inhibitory control predicted performance on reality questions. In Study 2, 95 children (4- and 5-year-olds) who were monolingual or bilingual solved similar problems. On appearance questions, groups performed equivalently but on reality questions, bilinguals performed better (once language proficiency had been controlled). The difference is attributed to the advanced inhibitory control that comes with bilingualism.
