The problem of this study is to investigate the differences in perceived parental behavior patterns, child rearing attitudes, and learning disabilities in natural and adoptive families. The purposes of this study are to compare the child rearing attitudes of adoptive and natural parents, to compare the child's perception of parental behavior in adoptive and natural families, to discover if the two groups differ in their ability to predict their children's perceptions of parental behavior, and to investigate the incidence of learning disabilities among adoptive children. Findings indicate that significant differences exist between natural and adoptive parents as measured by the PAS and the CRPBI-R. Adoptive fathers are not as likely as natural fathers to feel it is impossible to change a child from his already determined way of behaving and believe parental or environmental influences to be more important than natural or inherent causations. The younger the child was at the time of adoption, the better the adoptive parents were able to predict what the child would report about parental discipline. Adoptive parents are also found to be more accepting of childhood behaviors and feelings and have more mutual trust and understanding of their children than are natural parents. There is not a significantly greater proportion of adopted children in Plan A than natural children.

The problem of this investigation was to compare the linguistic competence of learning disabled and emotionally disturbed pupils by means of two performance tasks. Sixty subjects, seven-and-eight-year old monolingual public and private school pupils, were assigned to three groups of twenty subjects each, learning disabled, emotionally disturbed and normally achieving children. The majority of those in the learning disabled and the normally achieving groups were from middle-class families, with the majority of fathers owners of small businesses. A majority (17) of the emotionally disturbed group attended the public schools.

This thesis concerns the role of the Social Care Worker in interventions into unacceptable sexual behaviour in people who have a learning disability. It takes as point of departure ways in which support organisations and individual members of staff become aware that a service user’s sexual behaviour needs to be addressed. This raises issues about the service user’s human rights, confidentiality, and the concept of what it is to be ‘professional’ which can affect information sharing between support organisations and also between fellow support workers. In the case of the latter this relates to the workers status within the organisation, relations of power/knowledge which also has implications for the status of these workers as ‘professionals’. The thesis goes on to determine the support workers’ perceptions of what Bourdieu has termed, their ‘field’. That is to say, those behaviours they feel they can address without consulting health professionals. In addition to this, criteria used to decide when it is appropriate to consult health professionals is also described which thus demarcates their ‘field’ as perceived by the social care workers. The subsequent roles of the SCW whether working with or without input of health professionals is then discussed in terms of the individual worker’s ‘proximity’ or working relationship with the service user in question, and also their status within the support organisation. Findings suggest that some front-line workers who can claim closer ‘proximity’ to the service user may not have the same level of information about the behaviour as their managers who work off-site and do not have their direct care. Consideration is then given to accounts of situations in which input from health professionals is sought but is not forthcoming leaving SCWs and their organisations to deal with the behaviour in-house. Some of these such as sexual assault and rape are thus being treated in the community when otherwise the individuals concerned would be treated in locked NHS wards. Thus a new ‘field’ emerges requiring of the SCW a level of responsibility and skill that goes unacknowledged. The thesis ends by considering the feelings of workers involved in interventions into unacceptable sexual behaviour and concludes with recommendations on the education and support these workers require. Acknowledgement of the work they do and re-assessment of their status as workers is also recommended.

Developmental dyscalculia (DD) is a learning disability that is characterized by severe difficulties with acquiring age-appropriate mathematical skills that cannot be attributed to insufficient education, language skills, or motivation. The prevalence rate is estimated at 3-6%, meaning that a substantial portion of the population struggles to learn mathematics to such a large degree that it affects overall well-being and academic prospects. However, our understanding of the etiology of DD is incomplete and there are competing hypotheses regarding the characteristics of DD and its underlying causal factors. The purpose of the current thesis is to contribute to our understanding of DD from the perspective of cognitive psychology and cognitive neuroscience. To this end, we identify children with DD to identify the cognitive determinants of DD that hamper their ability to learn basic mathematics. It is believed that human beings are endowed with an innate ability to represent numerosities, an ability phylogenetically shared with other species. We investigate whether the purported innate number system plays a role in children with DD insofar as  failures in this system may undermine the acquisition of symbolic representations of number. Although some researchers believe DD is a monolithic learning disability that is genetic and neurobiological in origin, the empirical support for various hypotheses suggests that DD may be shaped by heterogeneous characteristics and underlying causes. The present thesis, and the studies presented therein, provides support for the notion that DD is indeed heterogeneous. We identify at least two subtypes of DD that are characterized by specific deficits in number processing, and one subtype that could more aptly be labelled as a mathematical learning disability, the causal factors of which are likely limited to deficits in non-numerical abilities. In addition, we locate candidate neurocognitive correlates that may be dysfunctional in DD. / Dyskalkyli är en specifik inlärningssvårighet som karaktäriseras av stora svårigheter med att tillgodogöra sig matematikkunskaper som inte kan härledas till bristande undervisningsmöjligheter, språkfärdigheter, eller motivation. Prevalensen av dyskalkyli uppskattas till 3-6%, vilket innebär att en ansenlig andel av populationen har sådana besvär att lära sig matematik att det påverkar deras allmänna välbefinnande och akademiska möjligheter. Förståelsen för dyskalkyli är emellertid knapphändig, men ett flertal konkurrerande hypoteser har föreslagits avseende dess karaktäristika och kausala faktorer. Syftet med denna avhandling är att öka vår förståelse av dyskalkyli utifrån ett kognitionspsykologiskt perspektiv och utifrån kognitiv neurovetenskap. Följaktligen identifierade vi skolbarn med specifika och stora matematiksvårigheter för att sedermera undersöka vilka kognitiva faktorer som underminerar deras förmåga att förvärva grundläggande matematikfärdigheter. Rådande uppfattning är att människan är utrustad med en medfödd förmåga att uppfatta och representera antal, vilket är en förmåga som vi fylogenetiskt delar med andra arter. Vi undersöker huruvida detta medfödda antalsuppfattningssystem är involverat vid utvecklandet av dyskalkyli hos barn, där ett dysfunktionellt antalsuppfattningssystem kan underminera förmågan att tillgodogöra sig symboliska representationer av antal. Gängse uppfattning gör gällande att dyskalkyli är en enhetlig och homogen inlärningssvårighet som genetiskt och neurobiologiskt betingad. Dock har ett flertal hypoteser angående orsaken till dyskalkyli fått empiriskt stöd, vilket möjliggör tolkningen att dyskalkyli snarare är en heterogen inlärningssvårighet med olika kausala faktorer och egenskaper. Föreliggande avhandling ger stöd för denna senare tolkning. Vi identifierar åtminstone två  subtyper av dyskalkyli, som vardera karaktäriseras av specifika svårigheter med numeriska färdigheter, samt en subtyp som mer korrekt bör benämnas som matematiska inlärningssvårigheter där bidragande faktorer sannolikt kan härledas till icke-numeriska förmågor. Vidare så identifierar vi potentiella neurokognitiva korrelat som är dysfunktionella vid dyskalkyli.

Using a multiple gating procedure, five elementary principals were identified as special education leaders. This descriptive study uses a multiple-case study design to explore principal’s (a) understanding and perceptions of instructional strategies associated with improved outcomes for students with learning disabilities (LD), and (b) their instructional leadership practices utilized to promote educators’ instruction of students with LD. Findings reveal that the majority of participants (n = 4) expressed at least a moderate understanding of effective instruction for students with LD, perceived implementation of these practices as necessary (n = 5), but reported mixed perceptions regarding feasibility. As expected, the five participants also described different levels of utilizing instructional leadership practices to promote educator’s instruction of students with LD. However, the two participants with advanced special education degrees were distinct from the others with respect to their combined high understanding, positive perceptions, and instructional leadership practices utilized to promote educators’ instruction of students with LD. Overall propositions indicate: (a) principals in this study who possessed higher understanding of effective instructional practices for students with LD and were interested in improving this understanding, were more apt to engage in instructional leadership practices to promote effective instruction for students with LD, (b) principal’s prioritization of developing a collaborative vision and practices among educators to promote effective instruction of students with LD may be beneficial to improving instruction for students with LD, and (c) principal’s intentional interaction and support with both general and special educators may lead to higher levels of collaboration among educators as well as more effective instruction for students with LD. / text

This study was designed to determine the factorial validity of specific components of the Reitan-Indiana Neuropsychological Battery with a learning disabled population. Scores of 42 children, 38 males, 4 females, ages 6.2 to 8.8 years were compiled on specific tests of the Reitan-Indiana. Principal component factoring of the original correlation matrix was followed by principal factoring, using a 4 factor solution; varimax rotation with six iterations produced the desired reduction of the correlation matrix; four factors emerged for the learning disabled population, which accounted for 53% of the variance: verbal intelligence, psychomotor speed, achievement, and memory. The factor structure that emerged was not consistent with the surface factors of the battery as conceptualized by its author suggesting that this battery may lack construct validity when used with a learning disabled population.

This study investigated the development of acquisition and long term retention processes in Learning Disabled (LD) and Non-Learning Disabled children aged 7-12. One hundred six subjects were randomly assigned to memorize either a list of unrelated words (with free recall), or a list of taxonomically related words (with recall cued by category). Each subject had a 16 word list presented in visual and auditory modes. The repeated recall paradigm alternated study and test trials, with a buffer activity between trials. The acquisition phase ended when the subject reached 100% criterion. After an interval of two weeks, each subject was given 5 additional recall tests. Acquisition results indicated significant main effects for age, group (LD, Non-LD) and list type (unrelated, categorized) on measures of trial-of-last-error and total-errors. Overall, the groups which acquired the lists most quickly were the older and Non-LD subjects, with the categorized list. There was a List x Group interaction on the trial-of-last-error. With the categorized list, only age was significant, and conversely, with the unrelated list, only group was significant. On the retention measures, there were main effects for list and group, with a List x Group interaction. The only significant age effect was with total-words on the categorized list. Over the five trials (repeated measures), there was a significant effect for trials. A consistent hypermnesia effect (increase in net recall) was predominant. Further model-based analyses (Brainerd, Kingma, Howe, & Reyna, 1988) revealed storage failure, rather than retrieval failure to be the major action in children's forgetting. Learning Disabled children had significantly more storage failure than the Non-LD children. Both groups had more storage failure on the unrelated lists. There was retrieval relearning with all groups. Results are discussed within the framework of the disintegration/redintegration theory, which pertains to the gradual weakening and redintegration of bonds that unite features to form a trace.

Hypotheses were proposed suggesting that learning disabilities predispose individuals toward anxiety and that special education intervention moderates the manifestation of anxiety. A regression analysis was performed with the outcome variable of Total Anxiety from The Revised Children's Manifest Anxiety Scale (RCMAS; Reynolds &amp; Richmond, 1985) with data from 91 elementary students with learning disabilities. Predictor variables included Wechsler Intelligence Scale for Children-Revised (WISC-R; Wechsler, 1974) Full Scale Intelligence Quotient (IQ), absolute WISC-R Verbal-Performance IQ differences, discrepancies between WISC-R Full Scale IQs and Woodcock-Johnson Psycho-Educational Battery (WJPEB; Woodcock &amp; Johnson, 1977) achievement scores, percentage of special education intervention per day and percentage of special education per student's total school experience. A stepwise regression analysis resulted in Full Scale IQ (R² =.075) and percentage of special education per day (R² change =.050), as the only variables entered and retained in the equation to predict RCMAS Total Anxiety. The relationship between special education per day and Total Anxiety was positive (Pearson r =.27), which was opposite the hypothesized direction. When entered last in the complete prediction model, special education per day had a significant (p < .05) part correlation of.23. Full Scale IQ had a significant Pearson correlation with RCMAS Total Anxiety (r = -.27) but the part correlation (r = -.20) did not retain significance when the effects of the other predictor variables were held constant. The Learning Disabilities (LD) subject group had a mean Total Anxiety score of 50.6 (SD = 11.7), which was not significantly different than the RCMAS normative group. Separate stepwise regression analyses with outcome variables of the RCMAS factor scores identified predictor variables of Full Scale IQ, percentage of special education per day, or both as best predictors. Special education per total school experience had a significant part correlation (r = -.23) with the Physiological Anxiety factor when entered last in the complete prediction model. The need for cross-validation and further study is emphasized. Alternative explanations for the results of the present study are presented.
