The Effects of "Errorless" Training and Testing on the Performances of Typically Developing Children During Acquisition and Retention.Arnadottir, Iris 12 1900 (has links)
This study examines the effects of two teaching procedures and two testing procedures (“Skip” and “Guess”) on acquisition, retention and generalization of learning. Three typically developing females between the ages of 8 and 11 learned the 24 lower case letters of the Greek alphabet. Half of the letters were taught with the “Skip” procedure and the other half with the “Guess” procedure. The “Skip” procedure produced faster and more efficient learning than the “Guess” procedure. The “Skip” procedure also resulted in better initial retention (4 weeks), but this effect disappeared in subsequent retention tests. The training conditions did not have differential effects on generalization tests across learning channels, except for the Free/Say channel.

A Spanish Version of the Children's Sleep Habits Questionnaire (CSHQ)Lara Ledesma, Duvia 01 June 2014 (has links)
This study was done to validate a widely used parent questionnaire that assesses sleep problems in children ages 4‑10. To date, no Spanish‑language sleep questionnaire is available for the Spanish‑speaking population. Research has found that sleep problems affect both typically developing children and children with developmental disabilities, potentially detracting from their quality of life. Spanish is the second most frequently spoken language in the United States, so it is of high importance to make available a Spanish‑language sleep questionnaire. The Children’s Sleep Habits Questionnaire (CSHQ) was chosen to be translated. The norming data for validation of the CSHQ‑S included 151 children from the community sample and 30 children from the clinical sample. A confirmatory factor analysis failed to replicate the purported internal structure of the English‑language CSHQ. Subsequent exploratory factor analysis yielded a unique 5‑factor solution which generally met criteria of reliability and validity. Our results show that children with disabilities experience more sleep problems than typically developing children. The CSHQ‑S can be considered to be a good Spanish‑language sleep measure in typically developing children and children with disabilities.

The Attitudes of typically developing adolescents towards their siblings with autism spectrum disorderVan der Merwe, Christine January 2014 (has links)

Abstract
Sibling relationships are amongst the most influential relationships in one’s life. Bringing autism spectrum disorder (ASD) into these interactional dynamics has a marked influence on these relationships for both the sibling with ASD and the typically developing siblings. The main aim of this study was to investigate how typically developing adolescents describe their present attitudes towards their sibling with ASD, compared to their attitudes when they were younger. Thirty typically developing adolescents who have siblings with ASD were selected to complete the survey instrument, namely the Modified Lifespan Sibling Relationship Scale (MLSRS). The survey instrument operated on the conceptualisation of attitudes as consisting of three components: affective, cognitive and behavioural. The results indicated that the majority of adolescents have very strong positive feelings towards their sibling (affective component), both at the time of the research and when they were younger. Their beliefs about their siblings and their relationship with them (cognitive component) have become more positive as they became older. Their actual interaction (behavioural component) was, however, found to be significantly lower than their feelings towards their siblings (both as adolescents and as younger children) and their beliefs about their relationships as adolescents. This study highlighted the need for children who develop typically to be taught how to interact effectively with their sibling with ASD and the need for siblings to be provided with age appropriate information about their sibling’s disorder. The results also indicate that although most of the children seemed to be coping well with the extra demands placed on them they would nevertheless still be able to benefit from support groups for siblings of children with ASD. / Dissertation (MA)--University of Pretoria, 2014. / gm2014 / Centre for Augmentative and Alternative Communication (CAAC) / unrestricted

The Effect of Locomotor Assisted Therapy on Lower Extremity Motor Performance in Typically Developing Children and Children with Cerebral PalsyScheidler, Capi Seeger 05 1900 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Background: Ambulation is critical to a child’s participation, development of selfconcept,
and quality of life. Children with cerebral palsy (CP) frequently exhibit
limitation in walking proficiency which has been identified as the primary physical
disability. Traditional rehabilitative treatment techniques to improve ambulation for
children with CP reveal inconsistent results. Driven gait orthosis (DGO) training is a
novel approach focusing on motor learning principles that foster cortical neural
plasticity.
Objective: The objectives are to determine if: (i) the lower extremity muscle activation
patterns of children with CP are similar to age-matched TD children in overground (OG)
walking, (ii) DGO training replicates muscle activation patterns in OG ambulation in TD
children, (iii) the lower extremity muscle activation patterns in OG walking of children
with CP are similar to their muscle activation patterns with DGO assistance, and (iv) DGO
training promotes unimpaired muscle activation patterns in children with CP.
Methods: Muscle activity patterns of the rectus femoris, semitendinosus, gluteus
maximus and gluteus medius were recorded in the OG and DGO walking conditions of
children with CP and age-matched TD. The gait cycles were identified and the data was
averaged to produce final average gait cycle time normalized values.
Results: In comparing the variability of the muscle activation patterns within the
subject groups, CP DGO walking was considerably lower than CP OG. In comparing the muscle activation patterns in each condition, consistent differences (p < .05) were noted
in terminal stance, pre-swing and initial swing phases of gait with the DGO condition
consistently revealing greater muscle unit recruitment.
Conclusion: The results indicate that training in the DGO provided the ability to practice
with measurably repetitive movement as evidenced by decreased variability. Consistent
differences were noted in muscle activation patterns in the terminal stance, pre-swing
and initial swing phases of gait when most of these muscles are primarily inactive. The
alteration in ground reaction force within the DGO environment may play a role in this
variance. With the goal of normalizing gait, it is important that the effect of these
parameters on ground reaction forces be considered in the use of DGO rehabilitation.

The development of children's perception of hierarchical patterns : an investigation across tasks and populations / Le développement chez l'enfant de la perception de pattern hierarchique : une investigation au travers de différentes tâches et populationsPuspitawati, Ira 07 October 2011 (has links)
Pas de résumé / The thesis investigated the development of children’s global/local processing hierarchical patterns introduced by Navon (1977). The objectives were to understand more comprehensively the developmental characteristics of children’s perception through their global and local processing of hierarchical patterns, by considering the effects of age, stimuli properties, duration of exposure to the stimuli and gender in a perceptual task and a drawing task. These effects were tested in 3 different populations: typically developing children, children with mental retardation and early blind children. The results revealed that typically developing children attended to both the local and global level of processing but these modes of spatial information processing operated independently. In a first step, children before 4 years of age showed dominance of local processing and then a more global processing developed at 4 years of age, and at 5 years of age integrated responses began to emerge. Early blind children showed similar developmental characteristics, although there was a protracted period of local processing dominance. Indeed, these children mainly produced local responses at ages of between 6 and 10 years, and then developed more global responses at 11-12 years and continued to integrate the two levels of analysis at later ages. On the other hand, global dominance was shown in children with mental retardation and their development was affected more by mental age than by chronological age. Moreover, their responses were shown to be sensitive to the fact that meaningful object could be located at the local level, enhancing local processing in this case. These results need further confirmations as the studies of global/local processing in atypical children are not numerous. In particular, the effect of duration of exposure to the stimuli should be further analyzed, because this factor did not seem to have a great effect in our experiments while it seemed more powerful in other studies carried out with adults. Replication of the study with children with mental retardation appears also important to plan for future work, because we can have some doubt relatively the absence of modification through ages of the way these children perceive hierarchical patterns. Finally, defining more precisely what may underlie the gender differences seems also worth to explore since gender did not show a major effect in our results.

The attitudes of typically-developing children towards participation with their siblings with severe speech and language disabilitiesHansen, Maryke 29 August 2012 (has links)
Sibling relationships and the interaction within these relationships play a central role in children’s general development and will therefore impact on functional outcomes of children with severe speech and language disabilities. Siblings of children with disabilities have often felt excluded from family interactions, possibly causing negative attitudes towards participation with their siblings, in turn impacting negatively on the functional outcomes of their siblings with disabilities. The main aim of this research is to determine the attitudes of typically-developing children towards participation with their younger siblings with severe speech and language disabilities in four everyday life situations, namely: play (major life areas), communication, activities of daily living as part of domestic life and interpersonal relationships (time and responsibility issues). Twenty-seven older, typically-developing siblings of children with severe speech and language disabilities were selected to complete the measuring instrument (SAS). The results indicated that the participants held the most positive attitudes towards participation in play (major life areas) but that they held less positive attitudes towards communication participation and that they were least positive about participation in interpersonal relationships (time and responsibility issues). This study succeeded in documenting attitudes of siblings towards participating in four everyday life situations with their younger sibling. It is envisaged that these results will provide tentative guidelines for how activity-based interventions can best be structured to support both the child with a disability and their sibling.
