Comprehension of televised stories by preschool children with ADHD.

Investigated visual attention to and story comprehension of televised stories in 4- to 6-year-old children with attention deficit hyperactivity disorder (ADHD) and comparison children. Half of the children in each group watched the program with toys in the room, and the other half watched without toys. Visual attention to the television was recorded, and story comprehension was assessed by performance on cued recall questions. All children attended significantly less when toys were present, but the difference when toys were present was greater for children with ADHD. The groups did not differ on recall of factual information when toys were absent. When toys were present, the comparison children showed no decrement in performance on factual questions, whereas the performance of children with ADHD was significantly worse. On questions testing causal connections, the children with ADHD performed more poorly than comparison children regardless of whether toys were present. Implications of these results for understanding and treating the academic and social difficulties of children with ADHD are discussed.     

Keeping track: the function of the current state buffer

The Current State Buffer has been proposed to account for our ability to keep track of significant stimuli in our immediate environment. The three experiments reported here were designed to test the independence of the Current State Buffer from the established components of Working Memory. Pre-schoolers were used in order to minimize the possible interference of other memory structures and complex strategies on the part of the subjects, thus allowing a cleaner test of the hypotheses. In the experiments, 180 pre-schoolers watched an Emu glove puppet tidy away toys into receptacles (the 'Tidy Emu Paradigm'), such that the number of pairings just exceeded their capacity for recall of the locations of toys in receptacles. We take this task to be a prototypical visuospatial Working Memory task. In the Object condition of Experiment 1, a Teddy was an object and was tidied away with the other toys. In the Character condition the Teddy was an animated character who interacted with the children and then went to sleep in one of the receptacles. Where Teddy was a character, all children remembered his location even though they had not been asked to; when he was an object only half of the children were correct despite explicit instructions to remember. More crucially, the location of the other toys was better recalled for children in the Character condition than those in the Object condition. These data are taken as evidence for the independence of the Current State Buffer from the Visuospatial Sketchpad. Other explanations, such as a von Restorff effect, are considered, and Experiments 2 and 3 test and reject these as possibilities.     

Comprehension of televised stories in boys with attention deficit/hyperactivity disorder and nonreferred boys

Two studies compared comprehension of televised stories by 7- to 12-year-old boys with attention deficit/hyperactivity disorder (ADHD) and nonreferred comparison boys. Boys watched one show with toys present and one with toys absent. Visual attention was continuously recorded, and recall was tested after each show. Across studies, visual attention was high with toys absent but decreased sharply with toys present for boys with ADHD. Groups showed similar levels of cued recall of discrete units of information regardless of differences in attention. When recall tasks and television story structure required knowledge of relations among events, the reduced attention of boys with ADHD interfered with recall. Although visual attention of comparison boys also decreased to some extent with toys present, there was no such decrement in recall. Implications of the difficulties children with ADHD have in integrated story comprehension are discussed.     

Development of attention and distractibility in the first 4 years of life

This observational study describes the early development of attention and discractibility. Under several conditions of distraction, 172 children at 10, 26, and 42 months of age played with toys. Attention to the toys was coded as casual, settled, or focused. All 3 levels of attention changed with age, withcasual attention decreasing and focused attention increasing. The 10-month-olds were more distractible than the other children, even during focused attention. The infants were most distracted by the auditory-visual distractor, whereas the oldest children were most distracted by the visual distractor. Some 42-month-olds showed evidence of being more focused in the presence of distractors. Overall, the results point to a developmental transition in the processes underlying attention during play.     

An economical,humane, and effective method for short—term suppression of hand mouthing

Self-injurious behavior (SIB) is a serious health hazard, especially among individuals with severe and profound mental retardation, sometimes leading to drastic therapeutic measures. Environments in which there are long periods with minimal opportunities for constructive activity are conducive to the development of SIB, but even highly motivated, hard-working caregivers sometimes have difficulty providing sufficient personal interactions to prevent it. In this case study, one person's self-injurious hand mouthing was significantly reduced by analyzing her toy play and consistently providing her with preferred toys. The results showed that careful and consistent attention to assuring that preferred materials are available for self-entertainment may be an effective and efficient method for managing some cases of SIB during times when other activities and treatments are unavailable.     

THE EVALUATION OF CHILDREN'S PLAY MATERIALS1

Although reliable data concerning toys' safety, durability, and appeal to children would be useful to parents, educators, and toy manufacturers, systematic procedures for evaluating toys and collecting such data have not been readily available. This paper describes a technology for carrying out such evaluations with children in free-play settings. Children entering the toy-evaluation area were each given a large tag, coded to indicate their names, age, and sex, to wear on the back of their shirt. Twenty-five toys were initially displayed on a table. Children were required by an adult to check out, and later return, any toy they selected for play. Every 5 min, an observer wrote down the tag number of any child playing with each of the 25 toys. The area was open for several hours daily, and at the end of each day a supervisor completed a toy-use questionnaire that identified problems associated with toy management, safety, and durability. Each interval in which a child was recorded as playing with a toy was considered five child-minutes of use for that toy. Data were summarized after each 5- to 10-day toy evaluation to indicate the total number of child-minutes of use attributed to each of the toys tested. The toys were then ranked from the most- to least-used. This measure of toys' overall use proved to be a reliable predictor of toys' appeal across many subjects and settings, and correlated well with our other analyses of toys' use. For example, toys used by individual children for long periods of time, and those toys most often chosen from the toy table were frequently the same toys that ranked high in overall child-minutes of use. Reliable differences in toys' appeal to boys and girls of different ages were observed. To test the generality of the toy-evaluation procedures, several experiments were conducted. To find out whether the popularity of certain toys depended on the number of children playing, a series of popular toys was made available first to only a single child at a time, then to any number of children. While certain toys required the presence of two or more children before they would be used, most toys were used by children both alone and in groups. The popularity of most toys, even the least-used toys, could be increased by having an adult play alone with the children. With some toys, an adult could maintain the play of several children at a time; with other toys, only one child at a time would be engaged. Another study showed a prolonged period of enforced sampling with little-used toys almost never increased their subsequent use once the enforced sampling procedures were discontinued. Finally, we found that having multiple copies of the same popular toys did not produce much more use of the toys than having single copies. The data produced by these evaluation procedures could be helpful to parents and educators in selecting desirable toys, and to manufacturers in improving the toys they develop and market. Future research might involve developing procedures that would encourage concerned adults to carry out toy evaluations in their own communities.     

Women’s sex-toy parties: Technology, orgasm, and commodification

This article presents participant-observation research from five female-only sex-toy parties. We situate the sale of sex toys in the context of in-home marketing to women, the explosion of a sex industry, and the emergence of lifestyle and body politics. We explore the significance of sex toys for women as marketed in female-only contexts, paying particular attention to the similarities and differences with Tupperware’s marketing of plastic that promises happiness to women. We argue that sex-toy sales follow the exact patterns of Tupperware sales but, since the artifacts sold are for the bedroom rather than the kitchen, foster an even greater sense of intimacy between the women—which has both positve and negative consequences for thinking critically about the commodification of sexuality, bodies, and lifestyles in our capitalist culture. Vibrators and other sex toys constitute the technological route to a self-reflexive body project of female orgasm. We ask to what extent such a body project, achieved primarily through an individualistic, capitalistic consumption model, can offer a critique of normative discourses of heterosexual sex and identity. Is this new plastic purchased at parties liberatory or just another form of containment? In other words, how much Tupperware does a woman really need to buy, before she’s been bought?     

Young children's interest in live animals

Animals are important stimuli for humans, and for children in particular. In three experiments, we explored children's affinity for animals. In Experiment 1, 11‐ to 40‐month‐old children were presented with a free‐play session in which they were encouraged to interact with several interesting toys and two live animals – a fish and a hamster. Experiment 2 used the same methodology with 18‐ to 36‐month‐old children and two additional animals – a snake and a spider – to examine whether children's behaviours would differ for benign and potentially threatening animals. Finally, in Experiment 3, a more controlled paired‐preference paradigm was employed to assess 18‐ to 33‐month‐old children's interactions with three live animals – a fish, hamster, and gecko – versus three physically similar toy animals. Across all three experiments, children interacted with the animals more often than with the toys. Further, they behaved differently towards the animals than the toys, talking about the animals more than the toys and asking more questions about them. The parents of the children also spent more time interacting with the animals, directing their children's attention more towards the animals than the toys. This research supports the idea that humans have an affinity for animals that draws their attention to animals, even when attractive toys are present.

The Child Attachment Interview: a psychometric study of reliability and discriminant validity

While well-established attachment measures have been developed for infancy, early childhood, and adulthood, a "measurement gap" has been identified in middle childhood, where behavioral or representational measures are not yet sufficiently robust. This article documents the development of a new measure--the Child Attachment Interview (CAI)--which seeks to bridge this gap. The CAI is a semistructured interview, in which children are invited to describe their relationships with their primary caregivers. The coding system is informed by the Adult Attachment Interview and the Strange Situation Procedure, and produces 4 attachment categories along with a continuous measure of attachment security based on ratings of attachment-related dimensions. The main psychometric properties are presented, including interrater reliability, test-retest reliability, and concurrent and discriminant validities, both for normally developing children and for those referred for mental health treatment. The CAI correlates as expected with other attachment measures and predicts independently collected ratings of social functioning. The findings suggest that the CAI is a reliable, valid, and promising measure of child-parent attachment in middle childhood. Directions for improvements to the coding system are discussed.     

Patterns of toy play: An analysis of sex differences

Kindergarten children were videotaped playing with female- and male-traditional toys as well as nonsex-typed toys. Coders calculated time spent by each child in behavioral categories (positive and negative comments, aggression, nurturance, movement, noise, and gadgetry) and rated children on scales (talkativeness, activity, familiarity, enjoyment, proximity, appropriateness, and gentleness). Sex differences were revealed on most dimensions. Boys were rated as familiar with, enjoying, and playing appropriately with two toys (male-traditional and nonsex-typed) and girls on the female-traditional toy. Girls paid more attention to details of the toys, while there were few differences on aggression and movement. Data suggest that children develop varying patterns of play with the same toy—based on their earlier experiences with play materials. Agents promoting these differences (parents, teachers, and peers) are discussed, as are implications of the findings for children's development of skills and cognitive abilities.Portions of this report were presented at the annual meeting of the American Psychological Association, Toronto, August 1978. The author wishes to thank the San Bernardino Unified School District for help in conducting the research, and Lorraine Gorski and Dan Kelso for their work as coders.     

The effects of methylphenidate on various types of activity level and attention in hyperkinetic children

The effects of methylphenidate on a number of objective measures of activity level and attention were assessed on three repeated occasions in four types of settings: free play, movie viewing, testing, and restricted play periods. Subjects were 36 boys between 5 and 12 years of age and of average intelligence. Of these, 18 were diagnosed as hyperkinetic and participated in a double-blind drug-placebo crossover design. The remaining 18 boys, matched in age and IQ with the hyperkinetic children, served as a control group and received no drugs. Results indicated that compared to placebo, methylphenidate significantly reduced wrist, ankle, locomotor, and seat movement activity in the hyperkinetic children regardless of the type of setting in which the measures were taken. Relatively fewer significant drug effects were noted on the measures of concentration or attention. While concentration to reaction time, maze performance, and a movie viewing task improved during drug treatment, the length of attention to toys in free play was not significantly improved. Parental ratings of activity level were also improved by the drug. The hyperkinetic children were also observed to increase their level of task-irrelevant activity over time while control children remained relatively stable in activity over repeated assessment. Despite the positive drug effects, clinical observations suggested that methyl-phenidate may have reduced the interest of some children in their environment.     

Noticing and commenting on what’s new: differences and similarities among 22‐month‐old typically developing children,children with Down syndrome and children with autism

Twenty 22‐month‐old typically developing children (TD), 11 children with Down syndrome (DS) and 10 children with autism (A), all functioning at a one‐ or two‐word linguistic level, were given eight series of four toys to explore. In each series, the first three toys (i.e. Trials 1–3) were identical, but the fourth toy (i.e. Trial 4) differed on a property or in identity. The children sat beside their mother and the experimenter while exploring the toys. Of interest was whether (1) the TD children would show more exploratory and communicative behavior related to the toys on Trials 1 and 4 than 2 and 3, and (2) how the response patterns of nontypically developing children would compare. The DS group showed a pattern of responding similar to that of the TD group with respect to their attention and interest in the toys, although a much lower rate of communicating with their mother. In contrast, the A group differed significantly from both other groups with respect to both the toys they found of interest and the timing of their topic initiations. Implications for observing declarative communication among children with Down syndrome and children with autism are discussed.     

Psychological and stress hormone correlates in early life: a key to HPA-axis dysregulation and normalisation

Substantial recent research has focused on examining hormone indicators of psychosocial stress and on how relationships between stress and hormone changes might be linked to chronic illness. Particular attention has been paid to disease progression in cancer and HIV/AIDS. This focus has generated a plethora of research which has contributed both theoretically and clinically to the understanding of disease experience and the rate of disease progression. Measurement of salivary cortisol levels and diurnal variation has substantially advanced research methodology. Applying the unifying concept of allostasis and accumulated lifetime stress, this review attempts to assess the relevance of psychological and stress hormone correlates to disease resistance and health, through an examination of such correlates on the experience and outcomes of stress during childhood. Focus is on the role and importance of naturalistic social stress experiences such as school transition in healthy children, with emphasis on salivary cortisol as an endocrine marker of HPA-axis activation. It is argued that differing research perspectives offer valuable insight into the often assumed but largely unexplored links between early life experience and subsequent physical health outcomes in adulthood. Longitudinal studies incorporating measures of acute physical health outcome and of learning and memory are clearly needed.     

Psychiatric diagnoses of infants and toddlers referred to a community mental health system

There has been increased interest in improving mental health assessment and treatment of young children. However, there are limited data regarding the prevalence of psychiatric disorders among infants and toddlers. The recent development of measures and classification systems that are specific to this age group has enabled researchers to begin to investigate the social, emotional, and behavioral problems of young children. The present study reviews the major research that has been conducted in this area and examines the prevalence of psychiatric diagnoses of infants and toddlers referred to a public community mental health system. The current investigation also compares the frequency of diagnoses of children who have been evaluated based on the Diagnostic and Statistical Manual (4th edition) with another group of children who were diagnosed based on the Diagnostic Classification: 0-3 system. Although there were some differences between the two samples and classification systems, analysis indicated that parent-child relational problems, adjustment difficulties, regulatory problems, and developmental disorders are some of the more common diagnoses prevalent among young children referred for outpatient treatment. As diagnostic measures and classification systems continue to improve, clinicians will have a better understanding of the mental health problems and treatment needs of young children.     

The Effects of Thematic Importance on Story Recall among Children with Attention Deficit Hyperactivity Disorder and Comparison Children

This study examined the recall of televised stories for younger (4-6 years) and older (7-9 years) children with and without attention deficit hyperactivity disorder (ADHD) under two different viewing conditions (toys present/toys absent). Each child watched two Rugrats television programs, once with toys present and once with toys absent. Immediately after viewing a program, the child completed a free recall of the observed story. Comparison children's recall increased more than ADHD children's as importance level increased, and comparison children recalled more information overall than children with ADHD. When toys were present, children with ADHD retold less coherent stories than comparison children, as indexed by smaller correlations between the story units recalled and the order of these units in the story. In summary, children with ADHD demonstrated multiple difficulties in story comprehension. These findings add to our understanding of the differences in higher-order cognitive processing abilities between children with ADHD and comparison children, and suggest important areas of focus in designing more effective academic interventions for children with ADHD.     

The Impact of Parenting Experience on Gender Stereotyped Toy Play of Children

The purpose of this study was to examine gender role socialization as a function of parenting experience in an actual toy play situation and as a function of adults' perceptions of typically gender-stereotyped children's toys. Each of 48 children (24 boys and 24 girls) played with 3 adults: either his or her own mother or father, a matched mother or father of another child, and a matched man or woman who was not a parent. The amount of time children and adults played with gender-specific toys, adults' categorization of toys into gender categories, and adults' desirability ratings of gender-specific toys were examined. The gender-sorting task revealed that adults did not agree with traditional expert categorizations of some of the toys, which suggests a shift in the perceived function of some traditionally stereotyped toys. Regardless of how parents sorted toys into categories, when playing with boys, most time was spent with masculine toys. With girls, however, there was greater flexibility in the categories of toys with which they played. Parenting experience influenced the perceived desirability of toys; parents found toys more desirable than nonparents but these differences did not affect the actual play session with children. These results suggest a change in perceptions of traditionally stereotyped toys and differences as a function of gender in what is appropriate gender-typing behavior.     

Toddlers’ Understanding of Peers’ Emotions

The second year of life sees dramatic developments in infants’ ability to understand emotions in adults alongside their growing interest in peers. In this study, the authors used a social-referencing paradigm to examine whether 12-, 18-, and 24-month-old children could use a peer's positive or negative emotion messages about toys to regulate their own behavior with the toys. They found that 12-month-olds decreased their play with toys toward which a peer had expressed either positive or negative emotion compared with play following a peer's neutral attention toward a toy. Also, 18-month-olds did not respond systematically, but 24-month-old children increased their toy play after watching a peer display negative affect toward the toy. Regardless of their age, children with siblings decreased their play with toys toward which they had seen a peer display fear, the typical social-referencing response. The authors discuss results in the context of developmental changes in social understanding and peer interaction over the second year of life.     

An analysis of choice making in the assessment of young children with severe behavior problems

We examined how positive and negative reinforcement influenced time allocation, occurrence of problem behavior, and completion of parent instructions during a concurrent choice assessment with 2 preschool-aged children who displayed severe problem behavior in their homes. The children were given a series of concurrent choice options that varied availability of parent attention, access to preferred toys, and presentation of parent instructions. The results showed that both children consistently allocated their time to choice areas that included parent attention when no instructions were presented. When parent attention choice areas included the presentation of instructions, the children displayed differential patterns of behavior that appeared to be influenced by the presence or absence of preferred toys. The results extended previous applications of reinforcer assessment procedures by analyzing the relative influence of both positive and negative reinforcement within a concurrent-operants paradigm.
