Effects of methylphenidate (Ritalin) on selective attention in hyperactive children

This study investigated the effect of methylphenidate (Ritalin) on the selective attention of hyperactive children designated as favorable or adverse responders to stimulant medication. Using a type II incidental learning paradigm, it was found that children in the drug condition recalled more central and less incidental stimuli than those children in the placebo condition. While no differential effects on recall were found for responder type, methylphenidate did affect the spontaneous overt labeling of central stimuli by the favorable responder group. Results were interpreted in terms of the role of methylphenidate in narrowing the focus of attention. Implications for the classification of hyperactive children as favorable and adverse responders were also discussed.This paper is based on a master's thesis completed by the first author in the Department of Psychology, University of Guelph, under the supervision of the second author.

Early rejected status and later social adjustment: A 3-year follow-up

Sociometric measures and rates of social interaction were obtained from 186 kindergarten children. Subjects were classified into popular, rejected, and average status groups on the basis of sociometric data. Teachers' ratings on the Bristol Social Adjustment Guides were obtained when the children were in grade 2 and again in grade 3. Analyses of variance showed rejected children to be significantly more acting-out than popular or average children by grade 3. Rejected children were rated as less physically attractive, doing less well in reading and in arithmetic. Negative peer nomination in kindergarten was more predictive of later acting-out in grades 2 and 3 than rate of interaction.Research was funded by Alberta Mental Health Advisory Council, and Alberta Advisory Committee for Educational Studies.

Children's Use of Different Information Types When Learning Homophones and Nonce Words

This study examines whether 3-year-olds are able to use ontological distinctions in homophone and nonce word acquisition. In the homophone (denotation-1 present) condition, children heard stories introducing second meanings of homophones; for example, a skate (i.e., fish). Stories contained perceptual information, information about theory-based properties, or filler material. Children identified the referent from 3 drawings depicting the familiar meaning, the secondary meaning, and a distractor. In the homophone (denotation-1 absent) condition, the picture of the familiar meaning was replaced with a distractor. The nonce word condition, a control condition, was identical to the homophone (denotation-1 present) condition except that a nonce word replaced the homophone. Children were rarely able to construct a second homophone interpretation when the familiar denotation was available. Interestingly, in the remaining conditions, children used information about the animate-inanimate distinction in choosing the referent. We discuss children's use of this ontological distinction when inducing word meaning.     

The development of communication: When a bad model makes a good teacher

Five experiments were conducted on what 6-year-old children learn about communication by switching listener and speaker roles with competent and incompetent adults and peers. Experiment I demonstrated that children become better communicators to adults after listening to competent adults, competent peers, and incompetent peers, but not incompetent adults. The age of the listener was shown to have an effect in Experiment II, with children becoming less effective communicators when speaking to a peer after listening to an incompetent peer but better communicators when speaking to an adult after listening to an incompetent peer. Experiments III, IV, and V were designed to determine why children do not improve or deteriorate after listening to incompetent adults. It is not deficient memory: Children remember well the ambiguous messages of adults (Experiment IV). It is not implicit demands to be polite to an adult (Experiment III). It is that children think the ambiguous messages of an adult are competent (Experiment V). Mixing the authority and prestige of an adult with incompetent messages leads the child to ignore the adult's behavior as a standard for his or her own performance. These results suggest that social learning of communication skills might occur best when the child can learn what not to do by interacting with peers and what to do when interacting with adults.     

Social information processing and sociometric status: Sex,age, and situational effects

Theoretically based measures of social information-processing patterns in specific situations were developed and administered to popular, average, socially rejected, and socially neglected girls and boys in the first, third, and fifth grades (total n=95). Measures included interpretations of peers' intentions, quantity and quality of responses generated to problematic stimuli, evaluations of responses, and enactments of particular responses. Three kinds of situations were generated empirically as stimuli: being teased, being provoked ambiguously, and initiating entry into a peer group. Deviant children (rejected and neglected) were found to respond deficiently compared to average and popular children, but only in the situation in which they were teased. Older children performed more competently than younger children in all three situations. Interactions among gender, sociometric status, and age also were found. Findings were interpreted as evidence of the elusiveness and complexity of social information-processing defects among low sociometric status children.The authors wish to acknowledge the support of the staff of the Monroe County Community School Corporation in the conduct of this research.

Selective attention in children with reading problems: A developmental study of incidental learning

The performance of poor readers and control children at three grade levels, first, third, and fifth grades, was compared on an incidental learning task adapted by Hagen (1967). A significant group by task interaction in a repeated measures ANOVA indicated that reading ability was differentially related to performance on the tasks. Relative to control children at all grade levels, poor readers obtained lower scores on the central task and higher scores on the incidental task. The absence of a grade × task × reading ability interaction indicated that selective attention follows the same developmental course in poor readers as in control children. The data suggest that the development of selective attention as reflected in performance on this task is delayed from 2 to 4 years in poor readers.We wish to thank the Sachem School District for permission to test the children, Mr. Morgan, reading specialist, and the teachers and children involved for their cooperation.

Stereotyping of sex role in preschoolers in relation to age,family structure,and parental sexism

Forty-eight boys and 48 girls aged between 32 and 64 months were tested for stereotyping of sex role using a toy-preference technique. Scores for overt and covert measures of sexism and awareness of the dimension of sex-role stereotyping were also obtained from both parents of each child, as well as information on the target child's siblings. Analysis indicated the developmental nature of stereotyping of sex role in both boys and girls and the surprising finding that older siblings are much more important in the development of such stereotyping than are sexist parents. The influence of the child upon parental attitudes is also apparent. These findings and their interrelationships are discussed, suggesting new directions for research.The author wishes to thank Ann Barry, Director of the Glen Kindergarten, for her assistance in developing the materials used here and her extensive testing of the children included in this study.

The Use of Deception as a Compliance-Gaining Strategy

This study argues that the persuasive message behaviors of truthful and deceptive communicators may differ strategically. Participants (N = 283) responded to three interpersonally oriented persuasive situations and wrote out instances of compliance-gaining messages. Approximately half the respondents were required to use deception in their persuasive messages. A comparison of truthful and deceptive compliance-gaining messages revealed significant differences in the types of persuasive messages generated: Truthful persuaders composed messages involving positive and negative sanctions; deceptive persuaders composed messages based on rationale or explanation.     

Sustained attention in normal and in reading-disabled youngsters with and without ADDH

Three groups of children — one normal, one reading-disabled, and one reading-disabled with an additional diagnosis of attention deficit disorder with hyperactivity (ADDH)-were administered the Continuous Performance Test and compared on correct detections and three types of commission errors. All three groups showed a decline in sustained attention over the course of the task but not differentially according to diagnostic group. When younger and older subgroups were compared, the reading-disabled children were found to make significantly more correct detections with increased age, but not when the reading disability was accompanied by ADDH. The latter group of children also were differentiated by a type of commission error, previously associated with impulsive responding, that remained prominent in the older subgroup of dually diagnosed children. Reading-disabled children were differentiated by a second type of commission error which possibly was associated with inattention or short-term memory deficit and which diminished with age.The author would like to thank the staff of St. Patricks School and in particular its principal Sister Patrick Mary for her able administrative support of the study.

Popular and unpopular children's interactions during cooperative and competitive peer group activities

Popular and unpopular fourth-grade boys were videotaped as each attempted to gain entry into a cooperative and a competitive task involving two classmates who were average in popularity. During the competitive procedure, the unpopular entry children were more likely than their popular counterparts to break rules, emit silly noises, and appeal to authority. Children average in popularity directed more positive behaviors toward their well-liked classmates and more derisive and dominating behavior toward unpopular peers. Unpopular children exhibited less negative and immature behavior in the benign, tension-free atmosphere of the cooperative project and their peers were more tolerant toward them than during the competitive game. The findings suggest that contextual factors influence the social skills exhibited by the unpopular child. Implications for the treatment of peer relationship problems are discussed.This article is based on a doctoral dissertation by the first author under the direction of the second author.

Sensorimotor skills and language comprehension in autistic children

The objectives of this study were to examine the level of sensorimotor concepts of young autistic children and to relate these concepts to language comprehension. A sample of 16 autistic children with a mean mental age of 24.8 months was administered a standardized scale of sensorimotor intelligence and of receptive language. The autistic children demonstrated surprisingly sophisticated sensorimotor skills, particularly object permanence. While their initial performance was inferior to that of normal controls matched on mental age, particularly in their use of objects in combination, the difference between groups diminished on the second test administration. On the receptive language measure, the autistic children were less able to identify words correctly. The sensorimotor behavior of autistic children who demonstrated language comprehension did not differ from those who showed no language comprehension, except that the former group tended to use an object as an instrument somewhat more frequently. The fact that the autistic children were so impaired in language even with fairly good sensorimotor skills suggests that these skills, particularly object permanence, play a minor role in their language acquisition.Support for this research was provided by Biobehavioral Research Support Grant 516, Grant 12–41 from the March of Dimes, NIMH Postdoctoral Fellowship No. 1 F32 MH07550-01 (Ungerer), and NIMH Grant MH 33815-01.

Children's ability to make tentative interpretations of ambiguous messages

Consistent with prior research, 5- and 6-year-old children overestimated their knowledge of the intended referent of ambiguous messages. Yet they correctly revised their interpretations of ambiguous messages in light of contradicting information that followed immediately, while maintaining their initial interpretations of unambiguous messages (Experiment 1). Children of this age were able to integrate information over two successive ambiguous messages to identify the intended referent (Experiment 2). However, unlike 7- and 8-year-olds, they were no more likely to search for further information following ambiguous messages compared with unambiguous ones (Experiment 3). We conclude that although 5- and 6-year-olds' interpretations of ambiguous messages are not tentative at the outset, they can use source monitoring skills to treat them as tentative retrospectively, at least over short time spans.     

The development of communication: Attribute variation leads to contrast failure

Groups of 5-year-olds in two experiments described multidimensional triangles for a listener. The attribute differentiating referent triangles from nonreferent triangles in Experiment I was constant across trials for the simple condition group, while any one of three attributes was distinctive on a given trial for the complex condition group. One-adjective messages by subjects in the simple condition were virtually always informative; in the complex group, such messages were predominantly ambiguous. The boundaries of the variation effect were assessed in Experiment II. In addition to the simple-complex variation of the relevant attributes, the values of the irrelevant attributes either varied across trials in the diverse groups or remained constant in the constant groups. One-adjective messages were informative only in the simple-constant group; in the other groups, such messages were predominantly ambiguous. Thus, young children can base their communications on a comparative analysis of stimulus arrays, but performance deteriorates when there is any variation in relevant or irrelevant attributes. These results were discussed in relation to various theories of the development of meaning and communication: the cognitive overload theory, the broad context theory, and the perceptual saliency theory.     

Reading comprehension and understanding idiomatic expressions: a developmental study

The aim of the present study was to investigate idiom comprehension in school-age Italian children with different reading comprehension skills. According to our hypothesis, the level of a child's text comprehension skills should predict his/her ability to understand idiomatic meanings. Idiom comprehension in fact requires children to go beyond a simple word-by-word comprehension strategy and to integrate figurative meaning into contextual information. In a preliminary phase, we used a standardized battery of tests (Cornoldi & Colpo, 1998) to assess the ability of second graders and fourth graders to comprehend written texts. Three groups were identified at each age level: good, medium, and poor comprehenders. Children were then presented with familiar idiomatic expressions which also have a literal meaning (e.g., "break the ice"). Idioms were embedded in short stories: in Experiment 1 only the idiomatic interpretation was contextually appropriate, in Experiment 2 a literal reading of the string was also plausible in the context. A multiple-choice task was used in both experiments: children were asked to choose one answer among three corresponding to: (a) the idiomatic meaning; (b) the literal meaning; and (c) an interpretation contextually appropriate but not connected with the idiomatic or literal meaning of the idiom string. The results of both experiments showed that the ability to understand a text indeed predicted children's understanding of idioms in context. To verify whether possible improvements in children's comprehension skills might produce an increase in figurative language understanding, Experiment 3 was carried out. A group of poor comprehenders who participated in Experiments 1 and 2 was tested eight months later. The results of Experiment 3 showed that children whose general comprehension skills improved their performance on an idiom comprehension test.     

Of sex roles and strollers: Female and male attention to toddlers at the zoo

Research supports the conclusion that adults interact differently with children of different sexes. Laboratory and home studies indicate that fathers/adult males are the primary agents of sex typing and that mothers/adult females are the primary caretakers, especially regarding the managerial aspects of child care. Little attention, however, has been directed at the public display of these differences and their covariance. Observations were made of 6414 visitors to the Sacramento zoo, with 524 adult females, 524 adult males, and 524 toddler triumvirates targeted for specific analyses of adult-child interactions and caretaking behaviors. Males were significantly more likely to carry female toddlers than male toddlers, while females made no such distinction. Adult females were more likely than adult males to push the child's stroller. Related research on the father's role in sex-typing behavior and the role of the division of child care between parents in the maintenance and reproduction of gender roles is discussed.This research was supported by a University of California at Davis Faculty Research Grant to the second author. We thank R. J. Mitchell for his contributions, both in and out of his stroller.     

Developmental and individual differences in preschoolers' recognition memories: The influences of gender schematization and verbal labeling of information

Eighty-three 37-92-month-old children's gender schematization and recognition memories for gender-typed content were assessed. Verbal labeling of stimuli and age were positively associated with children's memories. Highly gender schematic children displayed better memories for gender-role consistent information and committed more gender transformation errors than less gender schematic children. Interactions between children's gender schematization, age, and labeling condition were observed. Labeling of stimuli facilitated less schematic children's memories for gender-role consistent information. Gender schematization was positively associated with younger children's memories, suggesting younger children's memories are more strongly mediated by gender schematization than older children's. Results support the position that studies of gender schema development require an integrated approach recognizing individual and developmental differences in gender schematic processing.Completion of this project was facilitated by funds received while the author was a National Institute of Mental Health Postdoctoral Fellow at the University of Denver: Grant 5T32 MH 15780-09.

Response to Abrusán,Shaw, and Elbourne

In my book Category Mistakes (OUP 2013), I discuss a range of potential accounts of category mistakes and defend a pragmatic, presuppositional account of the phenomenon. Three commentators discuss the book: Márta Abrusán focuses on a comparison between my book and Asher’s Lexical Meaning in Context, suggesting that Asher’s theory has the advantage of accounting not only for category mistakes, but also for additional phenomena such as so-called ‘coertion’ and ‘co-predication’. I argue that Asher’s account of all three phenomena is deficient, and, moreover, that it is far from clear that the latter two phenomena are related to that of category mistakes. James Shaw challenges two of my arguments against the MBT view. I respond to these challenges. Paul Elbourne provides a novel argument in support of my account of category mistakes, involving multi-sentence discourses and ERP experiments. I show that it is not entirely straightforward for my account to explain this data, but that his argument does ultimately provide support for my view.     

Fred Rogers and children’s spirituality: valuing the uniqueness of others and caring for others

Mister Rogers' Neighborhood was a safe haven advocating kindness, empathy, and caring for all children. Making everyone feel loved, Fred Rogers captured the attention and curiosity of young children across America with his compassionate manner, intentional listening skills, and respect for all individuals by encouraging children to feel good about themselves. This article explores the ministry of Fred Rogers and how his approach to children's spirituality focused on valuing the uniqueness of each individual, human connections through play, and caring for others by recognizing spiritual moments and teaching the whole child while appreciating the uniqueness of others. His genuine and patient presence had a healing quality, creating a world for children in which real learning and unconditional love could flourish. The messages of tolerance and acceptance by recognizing and respecting other's beliefs, and unconditional love and care, were beacons of hope for all.
