The Turner syndrome: cognitive deficits, affective discrimination, and behavior problems

Individuals with sex chromosomal anomalies are known to be at increased risk for learning problems and in some cases social or behavioral problems. Girls with an absent or structurally abnormal second sex chromosome (the Turner syndrome) have been found to have cognitive problem solving deficits and immature, inadequate social relationships. The present study attempted to link cognitive and social problems by assessing the girls' ability to process affective cues. 17 girls with karyotypes consistent with a diagnosis of Turner syndrome were compared to a group of 16 short-stature girls of comparable age, verbal intelligence scores, height, and family socioeconomic status on the Affective Discrimination Task, which required interpretation of affective intention from facial expression. The results revealed that the Turner syndrome girls were less accurate at inferring facial affect than the short-stature controls. Analyses revealed that the Turner syndrome girls performed more poorly on spatial, attentional, and short-term memory cognitive tasks and had more psychosocial problems than the short-stature controls. Ability to discriminate facial affect may be another area of cognitive weakness for girls with the Turner syndrome and may underlie the psychosocial problems found in this sample.     

Using CD‐ROM ‘electronic talking books’ to help children with mild reading difficulties improve their reading fluencg

Abstract

This article explains how ‘electronic talking books’ might be used to help children who have mild reading difficulties improve their oral reading fluency. Observations made during a study of three middle primary students with mild reading difficulties are analysed in order to address some associated practical issues.

It has been suggested that CD‐ROM ‘electronic talking books’ may be used to help children improve their oral reading fluency (Ford, Poe & Cox, 1995; Glasgow, 1996–7; Lewis, 2000). However, there has been little discussion about the issues teachers may need to consider in planning, implementing and evaluating interventions using them. The purpose of this article is to describe some facilitating factors and problems that emerged during a study into the use of electronic talking books to improve reading fluency, and to present some possible solutions to the problems. Although the participants of this study were nine‐year‐old boys who experienced mild reading difficulties, many of the issues that arose should be applicable to teaching students with a wider range of reading ability/disability.     

Differential risk for developmental reading disorders in the offspring of compensated versus noncompensated parents

When one or both parents have a history of developmental reading disorder (RD) in childhood, the risk to their offspring for developing reading problems is substantially increased. However, risk research has usually assumed a stability of reading problems across the lifespan (i.e., if a parent was affected in childhood, he or she remains affected in adulthood). Yet, some individuals with RD in childhood compensate for the disorder as they grow older. Both an environmental and genetic hypothesis would predict that the risk for RD in offspring will vary as a function of parental compensation. This study examined whether risk to offspring was dependent on the parents' successful or unsuccessful compensation for their childhood reading problems. Two large family data sets were analyzed (N=907). Diagnoses with either an age discrepant or IQ discrepant criteria essentially showed that having at least one still affected parent (i.e., RD both as a child and as an adult) put the offspring at a higher risk for RD than having at least one compensated parent (i.e., RD as a child but not as an adult). The lowest risk to an offspring occurred when both parents were never affected (i.e., not RD as a child or as an adult). The implications of these findings are discussed with regard to counseling and early diagnosis of reading problems.     

Closing a Virtuous Circle: Reciprocal Influences Between Theory and Practice in Studies of Reading Intervention

Abstract

The authors reflect on findings from three studies of different approaches to reading intervention (Al Otaiba et al., Denton et al., and Miller et al., all found in this issue). It is argued that the science of interventions for reading disorders is advanced and that these and other related studies provide a strong evidence base for guiding educational policy in this area. Reading interventions need to be based on theories of reading development and reading difficulty. Current causal models of reading development arguably have focused almost exclusively on the cognitive processes underlying reading development and how best to remediate deficiencies in such processes. Such models are typically silent on broader influences (motivational, attentional, and socio-cultural) on learning, however. It is concluded that future theories will need to be broadened in order to develop more effective interventions for children with a variety of reading and language learning difficulties.     

Patterns of performance on the Stroop Color and Word Test in children with learning,attentional, and psychiatric disabilities

The study presented here investigated the performance of children with learning, psychiatric, and attentional disabilities on the Stroop Color and Word Test. Forty‐three children diagnosed with a full battery of tests as learning disabled (LD [reading]) in grades K through 6 were matched on age, gender, ethnicity, and grade with 43 normal controls. They were also matched with groups of 43 children with psychiatric disorders and 43 children with attentional problems. All subjects were given the Stroop test, which took about 4 minutes per subject. The results indicated clear differences between the groups, with the LD and the psychiatric/attention deficit/hyperactivity disorder (ADHD) groups generating unique profiles different from the normal controls. The children with LD showed slower reading speed and less interference, while the subjects with ADHD and diagnoses showed impairment only on the Color‐Word score. A discriminant analysis using the three basic Stroop scales was able to significantly differentiate the LD group from the non–learning‐disabled (NLD) group (89%) and the LD group from a joint Psychiatric/ADHD group (86%). However, results were poorer for differentiating a joint LD/ADHD group from the NLD group (68%) and the LD from the ADHD group (59%). © 2002 Wiley Periodicals, Inc.     

Comorbidity of PTSD in anxiety and depressive disorders: Prevalence and shared risk factors

The present study aims to assess comorbidity of posttraumatic stress disorder (PTSD) in anxiety and depressive disorders and to determine whether childhood trauma types and other putative independent risk factors for comorbid PTSD are unique to PTSD or shared with anxiety and depressive disorders. The sample of 2402 adults aged 18–65 included healthy controls, persons with a prior history of affective disorders, and persons with a current affective disorder. These individuals were assessed at baseline (T0) and 2 (T2) and 4 years (T4) later. At each wave, DSM-IV-TR based anxiety and depressive disorder, neuroticism, extraversion, and symptom severity were assessed. Childhood trauma was measured at T0 with an interview and at T4 with a questionnaire, and PTSD was measured with a standardized interview at T4. Prevalence of 5-year recency PTSD among anxiety and depressive disorders was 9.2%, and comorbidity, in particular with major depression, was high (84.4%). Comorbidity was associated with female gender, all types of childhood trauma, neuroticism, (low) extraversion, and symptom severity. Multivariable significant risk factors (i.e., female gender and child sexual and physical abuse) were shared among anxiety and depressive disorders. Our results support a shared vulnerability model for comorbidity of anxiety and depressive disorders with PTSD. Routine assessment of PTSD in patients with anxiety and depressive disorders seems warranted.     

‘I just find it boring’: Findings from an affective adolescent reading intervention

Research suggests that reading engagement and motivation are strong predictors of reading performance. Reading motivation may decline as students approach adolescence, resulting in less time spent with text. To date, there has been no research on how practitioners might directly support students to address affective factors in reading. In this exploratory case study, three disengaged, Year 8 readers received five sessions of an affective intervention aimed at helping them explore and challenge their own ambivalence towards reading. Quantitative and qualitative data from pre‐, post‐ and three‐month follow‐up indicated a range of benefits in relation to reading engagement and motivation, including improved self‐efficacy, increased participation and the usefulness of talking about affective factors in reading. Findings are further examined and implications for practitioners are discussed.     

ADHD and reading disability in male adults: is there a connection?

The present study examined the comorbidity between attention-deficit/hyperactivity disorder (ADHD) and reading disability (RD) in male adults. Participants were 120 men, of whom 24 were classified as having ADHD. The basis for the diagnosis was two self-report scales validated by interviews and background data. An extensive battery was used to assess phonological abilities and various aspects of reading skills. No differences were obtained between adults with and without ADHD on measures of either phonological processing skills or word decoding, indicating a low comorbidity with RD. This finding was valid even when different criteria were used to diagnose RD. However, the two groups differed in reading comprehension, with individuals with ADHD performing poorly in tests of reading comprehension. These results are compatible with the view that reading comprehension involves many of the higher cognitive control functions assumed to be impaired in ADHD. However, these attentional control functions are not critical to word recognition, which is determined by a more encapsulated phonological processing module. The pattern of associations between ADHD and RD observed in the present study is explained with reference to the differential attentional demands of the two aspects of reading.     

Referral reasons for learning disabled students

Referral information for 269 LD students in grades one through five was examined. Referral reasons were classified according to three major types: (a) academic, (b) behavior, and (c) academic and behavior. These major referral types also were analyzed according to particular concern (e.g., reading deficits, attentional problems, etc.). The results indicated that the majority of students were referred for either academic (42%) or both academic and behavioral (41%) reasons; referrals initiated solely for behavior problems accounted for only 17% of the total. The grade level analysis revealed that academic concerns were less likely to be noted in the first and fifth grades, and that the number of referrals diminished as grade level advanced (51% of the sample was diagnosed by second grade). Referral statements within each major referral type tended to be general, as opposed to specifying particular concerns to be explored in the evaluation. Preservice and in-service training recommendations are given.     

GENDER MODERATES ASSOCIATION BETWEEN EMOTIONAL‐BEHAVIORAL PROBLEMS AND TEXT COMPREHENSION IN CHILDREN WITH BOTH READING DIFFICULTIES AND ADHD

Evidence suggests that higher order linguistic functioning such as text comprehension is particularly vulnerable to emotional modulation. Gender has been identified as an important moderating variable in emotional expression such that girls tend toward internalizing emotions (e.g., sadness, anxiety) whereas boys tend toward externalizing emotions (e.g., anger, combativeness), which may influence the relationship between emotion and text comprehension. The present study examined whether gender moderates the relationship between emotional‐behavioral problems and text comprehension among children (n = 187; boys = 115, girls = 72) with both word reading difficulties (RD) and attention‐deficit/hyperactivity disorder (ADHD), a sample widely acknowledged to be at increased risk for developing emotional‐behavioral problems such as anxiety, poor academic self‐concept, and delinquency. A moderated regression analysis tested for the significance of two separate interaction terms (i.e., gender × externalizing problems, gender × internalizing problems) after controlling for gender, IQ, basic reading skills, cognitive‐linguistic processes closely related to reading, attentional problems, internalizing problems, and externalizing problems. Results indicated that gender significantly and uniquely moderates the relationship between emotional‐behavioral problems and text comprehension. Specifically, text comprehension was relatively lower among girls with relatively higher externalizing problems, whereas no such association was observed among boys. These results contribute to our understanding of cognition–emotion interactions within reading development and raise important implications.     

Norman geschwind lecture: Geschwind’s lesson

Norman Geschwind had a profound effect on behavioral neurology, not only on the basis of his research and theories expressed during his lifetime, but also through the impact that he had on colleagues privileged to train under him or have their work personally influenced by him. My work falls into the latter category. Novel associations between brain function/structure and behavior characterized his professional contributions, and offer a model for those who follow in his footsteps. He correctly predicted that like aphasic disorders, developmental dyslexia might be associated with deficits in color naming expressed currently as deficits in Rapid Automatized Naming. He stimulated anatomic research regarding patterns of asymmetry and microscopic architecture leading to the establishment of the Orton Dyslexia Neuropathology Laboratory at Beth Israel Hospital, Boston. He predicted an association between autoimmune disorders and reading disorders, an association that proved to be of genetic origin. He further predicted that reading disorders, like language disorders, would be cross-cultural and, similarly, their mechanism of production would be cross-cultural, although affected perhaps by the structure of the language to be learned. His suspicion that the clinical impression of male gender preponderance in dyslexia was accurate and carried biologic significance has recently been reconfirmed by colleagues at the Mayo Clinic in Rochester, Minnesota. Finally, with respect to dyslexia, one should not be surprised that since affect is influenced by brain architecture, developmental disorders characterized by altered brain architecture might be associated with affective or other psychiatric phenomena. My own work suggests that the altered neuroanatomy in dyslexia may be accompanied by altered clinical neurophysiology, offering the possibility that in some developmental disorders, behaviors, including academic aptitude and cognitive function, might benefit from medications designed originally to lower the risk of clinical seizures. Perhaps Geschwind’s greatest lesson is to not assume that all we have been taught as dogma is truth. Rather, we must have a willingness to make clear perceptions and draw conclusions that come closer to the reality of the causal relationship between brain and behavior.     

Immune disorders and dyslexia

The Geschwind-Behan-Galaburda hypothesis of cerebral lateralization postulates an association between immune disorders and learning disabilities. So far, the empirical evidence for such a relationship has been ambiguous. The present study is an attempt to investigate the hypothesis in a population where all the individuals were affected by immune disorders. Thus, 29 students in a special school for asthmatic children (total number of students in the school: 32) were investigated. A number of reading tests with special focus on word decoding were administered. The parents filled in a detailed questionnaire on the prevalence of reading difficulties and immune disorders among the other family members. The proportion of students with reading problems — especially phonological problems — was much higher than would be expected in a normal population. Among the family members we also found an elevated incidence of both reading problems and immune disorders. A cautious interpreptation of these findings leads to tentative and partial support of the Geschwind-Behan-Galaburda hypothesis.     

Physical punishment, childhood abuse and psychiatric disorders

OBJECTIVES: Physical punishment, as a means of disciplining children, may be considered a mild form of childhood adversity. Although many outcomes of physical punishment have been investigated, little attention has been given to the impact of physical punishment on later adult psychopathology. Also, it has been stated that physical punishment by a loving parent is not associated with negative outcomes; however, this theory has not been empirically tested with regard to psychiatric disorders. The main objective of the present study was to investigate three categories of increasing severity of childhood adversity (no physical punishment or abuse, physical punishment only, and child abuse) to examine whether the childhood experience of physical punishment alone was associated with adult psychopathology, after adjusting for sociodemographic variables and parental bonding dimensions. METHODS: Data were drawn from the nationally representative National Comorbidity Survey (NCS, n=5,877; age 15-54 years; response rate 82.4%). Binary logistic and multinomial logistic regression models were used to determine the odds of experiencing psychiatric disorders. RESULTS: Physical punishment was associated with increased odds of major depression (AOR=1.22; 95% CI=1.01-1.48), alcohol abuse/dependence (AOR=1.32; 95% CI=1.08-1.61), and externalizing problems (AOR=1.30; 95% CI=1.05-1.60) in adulthood after adjusting for sociodemographic variables and parental bonding dimensions. Individuals experiencing physical punishment only were at increased odds of adult psychopathology compared to those experiencing no physical punishment/abuse and at decreased odds when compared to those who were abused. CONCLUSIONS: Physical punishment is a mild form of childhood adversity that shows an association with adult psychopathology.     

语文课堂教学任务的反思与重构——西部地区中学语文课堂教学低效现象研究

课堂教学任务是为达到课堂教学目标对课堂教学活动内容所做的系统性规定与要求。长期以来语文课堂教学存在的“任务错位”现象,是导致语文课堂教学效率低下的主要原因。要改变这种状况,就要科学认识语文课堂教学任务的构成要素及其关系,重构语文课堂教学任务要素系统。语文课堂教学任务要素包括境、情、知、思、读、写、听、说、悟。这九种任务要素又可以分为三个层次。其中“境、情、知、思”是基础层任务要素,“读、写、听、说”是操作层任务要素,“悟”是发展层任务要素。

Taxonomic separation of attention deficit disorders and developmental reading disorders

This investigation compared the behavior ratings and psychometric profiles of children with attention deficit disorders (ADD) and children with developmental reading disorders (DRD). ADD children showed no qualitative reading or spelling problems, although they were slightly behind expected levels of academic achievement. DRD children were significantly more impaired in academic attainment and showed evidence of qualitative disturbances in reading and spelling. DRD subjects did not differ from control subjects on ratings of hyperactivity, which was one of the defining variables of the ADD group. This evidence is interpreted as adding to a growing testimony that indicates that ADD and DRD are distinctly separate groups of disorders.     

The veridicality of punitive childhood experiences reported by adolescents and young adults

OBJECTIVE: The primary goal of the present research was to determine whether retrospective reports of childhood disciplinary experiences and perceptions of that discipline correspond to actual childhood events and whether the accuracy of that report was influenced by the affective state of the respondent. METHOD: Eighty-three adolescent and young adult males completed a retrospective measure of physical child maltreatment, Assessing Environments (AEIII), and the Brief Symptom Inventory (BSI). As children the participants had been observed naturalistically in their homes interacting with their parents an average of 10 years earlier. RESULTS: Analyses were consistent with the hypothesis that both current mood and actual observations of parent-child interactions during childhood predict self-reported recollections of childhood maltreatment by one's parents. Further the veridicality of such recollections appears to depend upon the objective specificity versus the perceptive nature of the questions used to elicit the recollections. CONCLUSIONS: The findings suggest that assessment instruments suitable for obtaining information regarding earlier childhood victimization must utilize behaviorally specific items. Thus, items that are either global or intimate a normative comparison should be avoided.     

The relationship between young children’s enjoyment of learning to read,reading attitudes,confidence and attainment

Background: While there is a considerable body of research exploring the relationship between older primary school children’s reading attitudes, confidence and attainment, there is a noticeable lack of research with younger children. Furthermore, there is relatively little research exploring the extent to which children’s reading attitudes, confidence and attainment are related to their enjoyment of learning to read.

Purpose: To understand the relationship between young children’s reading attitudes, reading confidence, enjoyment of learning to read and reading attainment.

Sample: Two hundred and three children (103 boys) with an average age of 6 years and 9 months (.32 years standard deviation) participated in this study. Children were from 11 primary schools in England, located within a wide range of socio-economic neighbourhoods.

Design and methods: All children completed questionnaires examining their attitudes to reading, reading confidence (using Progress in International Reading Literacy Study items) and enjoyment of learning to read. Children also completed an assessment of word reading. All assessments were administered individually.

Results: Children’s attitudes to reading, reading confidence and enjoyment of learning to read correlated with their word reading skill; however, only reading attitudes and reading confidence predicted variance in reading success. With regard to gender differences, girls reported more positive reading attitudes than boys, even after controlling for differences in reading skill.

Conclusions: Results highlight that the relationship between children’s reading skills and the affective aspects of learning to read develops from a young age. Therefore, methods of reading instruction need to foster affective aspects of reading, in addition to developing cognitive skills to best support young children’s reading development.     

The Attentional Blink in Developing Readers

The attentional blink refers to a reduction in accuracy that occurs when identifying the second of two targets presented within approximately 500 msec of each other. This research explored individual differences in the attentional blink in a sample of 86 children (aged 8–10) with normally developing reading skills. The attentional blink was examined in relation to general reading performance as well as specific orthographic and phonological reading subprocesses. No associations were evident between attentional blink duration and reading ability. However significant correlations did exist between each of the three reading measures and mean second target correct given first target correct (T2|T1) performance across all lags, with less skilled readers exhibiting inferior performance regardless of the temporal lag between first and second targets. Performance on a rapid naming task mediated some of the relationship between mean T2|T1 performance and reading, yet the association remained significant when this factor was accounted for.     

Effects of reading and writing on cerebral laterality in good readers and children with dyslexia.

The present study evaluated the idea that the hemisphere-specific cognitive demands of reading and writing may induce task-specific maladaptive patterns of language lateralization in children with dyslexia. Situation-specific lateralization was examined in a repeated measures design under three dichotic listening conditions: baseline, concurrent reading, and concurrent writing. Twelve males with phonological dyslexia, 8 to 12 years old, were compared to 12 age-matched and 12 younger reading-matched good readers. Lateralization patterns were examined for condition-specific relationships to pseudoword decoding, word recognition, reading comprehension, spelling, and arithmetic. The results show that dyslexia is not related to incomplete lateralization or to a failure to inhibit verbal processing in the right hemisphere during reading and writing. Reading increased the lateralization of the children with dyslexia, which had a negative relation to arithmetic; writing caused a decrease in lateralization, which was linked specifically to deficits in phonological decoding and visual word recognition. The results suggest that children with dyslexia suffer from a selective linguistic vulnerability to left-hemisphere interference from the idiosyncratic attentional and processing demands of particular school tasks. Dyslexia is a much more dynamic and environmentally sensitive disorder than previously thought.
