Lateralized sensorimotor asymmetries in normal, learning-disabled and brain-damaged young adults

Left-right asymmetries in sensorimotor abilities (based on the Tactile Finger Localization, Fingertip Number Writing, Finger Tapping, Grip Strength, and Tactual Performance Tests of the Halstead-Reitan Battery) were compared among groups of 30 normal, 60 learning-disabled, and 20 brain-damaged adults aged 17 to 29 yr. The normal and learning-disabled groups (which did not differ) had significantly fewer asymmetries than the brain-damaged group. However, 36% of the learning-disabled group who had a Halstead Impairment Index greater than or equal to 0.4, also had significantly more sensorimotor asymmetries than the normals. These results support the idea of an association between neurobehavioral deficits and learning disabilities for this age group.     

The effects of special education labels on teachers' behavioral observations,checklist scores,and grading of academic work

This study addressed the question: Do special education labels bias teachers' evaluations of children? Thirty primary level teachers were given different labels for the same child: learning disabled, educable mentally retarded, emotionally disturbed, normal, or no label. Teachers made behavioral observations from the same video-tape, completed a checklist, and graded the same academic work purportedly completed by the target child. Teachers' behavioral observations and grading of the academic work were not influenced by the special education labels, but the checklist scores were. Implications for the philosophical debate about the effects of labeling and for methods of classroom data collection by teachers are discussed.     

Teachers' perceptions of remediation possibilities of Dutch students in special education

Background. Research suggests that referral practices of teachers in regular education are not only affected by the level of learning difficulties but also by student behaviour and the level of students' parental involvement in education. It was hypothesized that teachers maintain a notion of the ‘ideal’ student, who has relatively good academic skills, is well behaved and has highly involved parents. Aims. The main question of this study was whether special‐education teachers' perceptions regarding remediation possibilities are similarly affected by student behaviour and the level of students' parental involvement. Sample. Nineteen experienced Dutch school teachers in special education each evaluated four students: two with relatively high and two with relatively low academic performance. Methods. Three questionnaires to assess learning difficulties, behavioural problems and the level of parental involvement were developed. Results. Teachers' perceptions of remediation possibilities were related to the severity of the learning difficulties and academic skill. Academic skill, in turn, was strongly related to the perception of the children's behavioural problems and parental involvement, which, in turn, links the perception of remediation possibilities indirectly to children's behavioural problems and parental involvement. Conclusions. Special education teachers may also hold an image of the ‘ideal’ student. Students with high academic achievement levels are perceived as having fewer behavioural problems and more highly involved parents than students with low academic achievement levels. Whether this is due to justified or unjustified teachers' perceptions is a matter for future research. What is important is that stereotyping of students (justly or not) poses a serious problem for the Dutch reintegration policy.     

Communication deviances: a comparison between parents of learning-disabled and normally achieving students

This study explored the relationship between parents' communication deviances and children's placement in a learning disability class. Participants were the parents of 30 learning-disabled students and 30 average students attending junior high school. Samples of communication were taken from parents' participation in an experimental task. Using a "blind" sorting procedure, raters were able to identify 87% of the learning-disabled students' parents by their high communication deviance scores and 77% of the average students' parents by their low communication deviance scores on the experimental communication task (p less than or equal to .0001). Implications for future research on the etiology and remediation of learning disabilities are discussed.     

Time sharing and dichotic listening asymmetry in normal and learning-disabled children

Time-sharing and dichotic listening techniques were used to examine cerebral lateralization for language function in 48 normal and 48 learning-disabled children. All subjects were matched according to age, sex, and handedness. An analysis of results indicated that both nornal and learning-disabled children demonstrated left hemisphere lateralization of language function on the time-sharing and dichotic listening tasks. However, no developmental trends were evident for either group. Differences observed in the performance of the normal and learning-disabled children may relate to how each group utilizes “verbal strategies” and processes simultaneous information in the left hemisphere. The results strongly question the notion that attributes learning disabilities to incomplete or delayed language lateralization and lend support to the notion that cerebral lateralization is not a developmental phenomena.     

Relationships Between Trait Anxiety,Demographic Variables,and School Adjustment in Students with Specific Learning Disabilities

The present study investigated relationships between dimensions of anxiety, age, gender, and school adjustment in students with specific learning disabilities (SLD). The 177 students with SLD completed measures of anxiety and school adjustment. The results of a hierarchical regression analysis indicated that age and gender together were not significant predictors of attitude to school, and that after the influence of age and gender had been removed students with more physiological and social anxiety, but less worry tended to have poorer attitudes toward school. A second hierarchical regression indicated that younger students reported more negative attitudes toward teachers, and after controlling for age and gender, students with more social anxiety reported more negative attitudes toward teachers. Implications for school personnel are discussed.     

Psychometric properties of the Sutter-Eyberg Student Behavior Inventory with rural middle school and high school children

This study examined the psychometric properties of the Sutter-Eyberg Student Behavior Inventory (SESBI) in a rural sample of children and adolescents. Thirty-eight 5th- through 12th-grade teachers completed the SESBI on 726 children in their classrooms. High Cronbach's alphas supported the reliability of the SESBI scales in this population. Higher SESBI scores were obtained by boys than girls and by African American students than Caucasian students, more so at lower grades. Teacher's race did not affect SESBI scores. In contrast to children with developmental delay, children with learning disabilities obtained higher scores than others on the SESBI Intensity scale but not on the Problem scale. This suggests that teachers of children with learning disabilities recognize the higher frequency of problem behaviors in their students but do not consider these behaviors to be problems for themselves. On both SESBI scales, children with developmental delay were not distinguishable from peers without developmental delays.     

Does ethnicity matter? The impact of stereotypical expectations on in-service teachers’ judgments of students

Ethnic minority students face many disadvantages in school, which might be due in part to teachers’ stereotypical expectations and attitudes. Dual process theories of impression and judgment formation specify person information that confirms or disconfirms stereotypical expectations as determinants of how judgments are formed. While expectation-confirming information should result in stereotype-based judgments, expectation-disconfirming information should lead to more information-integrating processes. Moreover, attitudes should also be affected in a positive way when a person encounters expectation-disconfirming information. The current study experimentally investigated these hypotheses with regard to stereotypical expectations about ethnic minority students. Eighty-three experienced teachers were randomly divided into four different groups. One group judged a below-average ethnic minority student (confirming) and another group a below-average ethnic majority student. Two other groups judged either an above-average ethnic minority (disconfirming) or ethnic majority student. When assessing a below-average student, teachers judged the confirming ethnic minority student as less proficient in language than the ethnic majority student. These differences could not be found for mathematical achievement or between the above-average ethnic minority and majority students. Attitudes toward ethnic minority students were not affected in the expected way. Findings are discussed with respect to their implications for future research.     

Tests that discriminate between dyslexic and other learning-disabled boys

Dyslexic and nondyslexic boys within a single community's learning-disabled class were given a set of tests; performance on each of these tests has been reported to be significantly impaired in other dyslexic children compared to learning-disabled and normal groups. Linear discriminant function analysis revealed that error types rather than levels of performance best separated the carefully matched learning-disabled groups. Slow naming and high percentage of “dysphasic” errors characterized dyslexic boys. Visual temporal-spatial matching and “configuration-deficient” perceptual errors characterized the adequate readers who have other learning disabilities.     

How does it feel to become a teacher? Emotions in teacher education

Academic emotions are central ingredients in student teachers’ learning. They have been shown to affect cognitive performance, motivation and achievement (e.g. Linnenbrink-Garcia et al. in Contemp Educ Psychol 36(1):13–24, 2011). However, until recently the role of emotions in student teachers’ learning has largely been neglected (e.g. Ketonen and Lonka in Proc Soc Behav Sci 69(24):1901–1910, 2012). The study focused on exploring the spectrum of academic emotions experienced by 19 student teachers in different academic activities. The results showed that student teachers experience a wide variety of emotions during their studies. A total of 18 different positive emotions and 20 different negative emotions were reported. They explicated more positive than negative emotions. Further investigations showed that student teachers reported more emotional experiences embedded in individual activities than in social activities. The results implied that the spectrum of academic emotions experienced by student teachers is wider than previous literature suggests, and that student teachers experience a wide range of academic emotions in various academic activities provided by teacher education.     

Evidence for a double dissociation between spatial-simultaneous and spatial-sequential working memory in visuospatial (nonverbal) learning disabled children

The paper describes the performance of three children with specific visuospatial working memory (VSWM) impairments (Study 1) and three children with visuospatial (nonverbal) learning disabilities (Study 2) assessed with a battery of working memory (WM) tests and with a number of school achievement tasks. Overall, performance on WM tests provides evidence of a double dissociation between spatial-simultaneous processes, underpinning the memorization item positioning in a spatial configuration, and spatial-sequential processes, which allow memorization of the presentation order. In both groups of children of the two studies, a selective impairment either on spatial-sequential or on spatial-simultaneous working memory tasks was observed. These data support the existence of -simultaneous and -sequential modality-dependent processes in visuospatial working memory and confirm the importance of distinguishing between different subtypes of visuospatial (nonverbal) learning-disabled children.     

INCREASING INDICES OF HAPPINESS AMONG PEOPLE WITH PROFOUND MULTIPLE DISABILITIES: A PROGRAM REPLICATION AND COMPONENT ANALYSIS

We replicated a program to increase indices of happiness among people with profound multiple disabilities and conducted a component analysis of the program. The program involved presentation and contingent withdrawal of stimuli that had been identified as preferred based on preference assessments and staff opinion. The program was implemented with 3 adult students and was accompanied by increased happiness indices for each student. Subsequent implementation of the two types of stimuli indicated that preferred stimuli based on preference assessments were more consistently accompanied by increased happiness indices than were preferred stimuli based on staff opinion. Social validity measures supported the definition of happiness, in that raters' subjective opinions of the students' happiness coincided with the observed happiness indices. Results are discussed regarding the importance and practical implications of using preference assessments for determining stimuli for increasing happiness indices. Future research areas are suggested, focusing on increasing happiness and other quality-of-life indicators during the daily routines of people with profound disabilities.     

Communication Deviances and Clarity Among the Mothers of Normally Achieving and Learning-Disabled Boys.

The main purpose of the study was to reexamine the association between maternal communication deviances and learning disabilities in children. In this study, we adapted and extended the procedure used b Ditton, Green, and Singer (1987). A two-part experimental task was used: one in which the child could not request any clarification of mother's insruction, and another in which the mother and child could communicate. Both communication deviances and the clarity of mother's communication were analyzed. The subjects were 60 mother-child paires in which half of the children had learning disabilities and the other haalf were normally achieving children matched for age and parents' SES. The dyads were vedetaped in a laboratory setting. The mothers o f learning-disabled (LD) children were found to give less exact instructions and to present more ambiguous messages to the child than the mothers of non-LD children.     

Restricted interests and teacher presentation of items

Restricted and repetitive behavior (RRB) is more pervasive, prevalent, frequent, and severe in individuals with autism spectrum disorders (ASDs) than in their typical peers. One subtype of RRB is restricted interests in items or activities, which is evident in the manner in which individuals engage with items (e.g., repetitious wheel spinning), the types of items or activities they select (e.g., preoccupation with a phone book), or the range of items or activities they select (i.e., narrow range of items). We sought to describe the relation between restricted interests and teacher presentation of items. Overall, we observed 5 teachers interacting with 2 pairs of students diagnosed with an ASD. Each pair included 1 student with restricted interests. During these observations, teachers were free to present any items from an array of 4 stimuli selected by experimenters. We recorded student responses to teacher presentation of items and analyzed the data to determine the relation between teacher presentation of items and the consequences for presentation provided by the students. Teacher presentation of items corresponded with differential responses provided by students with ASD, and those with restricted preferences experienced a narrower array of items.     

A comparison of methods for calculating a severe discrepancy

Given the substantial rise in the number of students identified as learning-disabled, increasing attention has centered on methods for determining a severe discrepancy between ability and achievement. Using scores from 86 learning disabilities referrals, we compared four such methods (a z-score discrepancy, an estimated true score discrepancy, an unadjusted regression procedure, and an adjusted regression procedure). Each student was evaluated with the WISC-R, PIAT, and K-ABC. A high degree of agreement was found between z-score and estimated true score difference approaches. Less agreement was found between the unadjusted regression procedure and the other methods. It was concluded that the four methods cannot be used interchangeably in the calculation of severe discrepancies. Of the four methods that were analyzed, the unadjusted regression procedure selected the smallest percentage of students.     

Memory, acquisition, and category clustering in learning-disabled children.

In Experiment 1, single trial, immediate-free recall of learning disabled and nondisabled children was compared. The primacy effect in learning-disabled children was lower, suggesting that rehearsal or other types of elaborative encoding may be deficient in these children. In Experiment 2, acquisition of randomly presented categorical lists in a multitrial-free recall task was compared in learning disabled and nondisabled children. One-half of each group was required to learn the same number of words (34 per list), whereas list length for the other half exceeded the primacy effect of each child in immediate-free recall to the same degree. When the same number of items was learned, acquisition was slower in learning disabled than nondisabled children. When the number of items varied according to the primacy effect of each child, acquisition of both groups was similar. Clustering was lower in learning disabled than nondisabled children. In Experiment 3, multitrial-free recall acquisition of categorical lists was examined in a subject-paced task. When the number of words learned exceeded the primacy effect of each child to the same degree, trials to criterion were similar in both groups but, when the children learned the same number of items, learning-disabled children required more trials to criterion. Presentation rates were faster in learning-disabled children. Presentation rates were negatively correlated with trials to criterion and positively correlated with clustering and primacy in immediate-free recall, suggesting that study time may be taken up by clustering, rehearsal, and/or other encoding strategies. Deficient elaborative encoding may be responsible for the slower acquisition of learning-disabled children.     

Toward operationalizing a psychoeducational definition of learning disabilities

An operational definition of “learning disabilities” is presented from the standpoint that classificatory psychoeducational definitions must ultimately relate to educational processes. Thus the condition should be described in terms of abilities crucial to educational achievement, and noneducational criteria should not be employed. It is pointed out that the most generally accepted current definition — which identifies children as “learning-disabled” on the basis of behavioral criteria, while excluding others because of etiological and other nonbehavioral factors — overlooks functional similarities among such groups as educable mentally retarded and emotionally disturbed children. These similarities warrant the inclusion under the rubric of “learning-disabled” of some children who may also be grouped within other diagnostic categories. Consequently, the profferred definition is based on a primary concern with day-to-day learning and management issues. Concepts subtended by the definition are operationally defined, and its relationship to programming is discussed.
