Teacher Attitudes towards the Inclusion of Children with Mild Hearing Impairments into the Regular School Settings

The study examined the attitudes of a sample of Zimbabwean teachers towards the inclusion of children with mild hearing impairments. Two hundred and forty-six primary school teachers participated in the study. The teachers completed the modified Attitude Toward Mainstreaming Questionnaire (ATMQ) (Larrivee & Cook, 1979). In addition, they also completed four measures on implementation concerns of inclusive education of children with mild hearing impairments (i.e., academic, management, social, and knowledge concerns). Analysis related the scores from these four measures to teachers' attitudes, school type, class sizes, professional qualifications and position in the school. Compared with teachers with lower professional qualifications, teachers with higher professional qualifications had more favourable attitudes towards children with hearing impairment. Teachers who taught at ordinary schools with special needs resource units had more favourable attitudes towards students with hearing impairment than those at schools without such units. Resource unit teachers welcomed social inclusion of children with mild hearing impairments. School administrators were concerned about the practice of including children with hearing impairments in regular school setting before inducting teachers.

The impact of conventional versus robust norming on cognitive characterization and clinical classification of MCI and dementia

We examined the impact of conventional versus robust normative approaches on cognitive characterization and clinical classification of MCI versus dementia. The sample included participants from the National Alzheimer's Coordinating Center Uniform Data Set. Separate demographically adjusted z-scores for cognitive tests were derived from conventional (n = 4273) and robust (n = 602) normative groups. To assess the impact of deriving scores from a conventional versus robust normative group on cognitive characterization, we examined likelihood of having a low score on each neuropsychological test. Next, we created receiver operating characteristic (ROC) curves for the ability of normed scores derived from each normative group to differentiate between MCI (n = 3570) and dementia (n = 1564). We examined the impact of choice of normative group on classification accuracy by comparing sensitivity and specificity values and areas under the curves (AUC). Compared with using a conventional normative group, using a robust normative group resulted in a higher likelihood of low cognitive scores for individuals classified with MCI and dementia. Comparison of the classification accuracy for distinguishing MCI from dementia did not suggest a statistically significant advantage for either normative approach (Z = −0.29, p = .77; AUC = 0.86 for conventional and AUC = 0.86 for robust). In summary, these results indicate that using a robust normative group increases the likelihood of characterizing cognitive performance as low. However, there is not a clear advantage of using a robust over a conventional normative group when differentiating between MCI and dementia.     

Instructive feedback: Effects of number and type

We evaluated the effects of presenting two instructive feedback stimuli of the same and different types for each target behavior taught. Four elementary school students with mild mental retardation were taught to name photographs of places of interest in the local community using constant time delay and instructive feedback. Initially, the four students were taught one set of photographs with one instructive feedback stimulus (name of the street on which the place was located) for each target photograph. All students learned to name all photographs, and three learned to name the street on which the place was located. The three students who learned to name the street for the place in the photograph were then taught three sets of photographs. Each set included two instructive feedback stimuli for each target photograph: Set 2 had one street name and one activity that occurred in the place; Set 3 had two activities per photograph, and Set 4 had one street name and one activity. The three students learned to name the photographs, but only learned to name the activities and not the street names that were presented through instructive feedback. These finds are discussed in terms of the factors that may control acquisition of instructive feedback stimuli and the implications for practice and future research.     

Cognitive effects of mild head injury in children and adolescents

A comprehensive review of recent neuropsychological studies of mild head injury (MHI) involving children and adolescents is presented. The seminal work of Rutter and his colleagues is reviewed. An alternative conceptualization of MHI as proposed by various researchers is elaborated and further research investigating the cognitive sequelae of MHI is reviewed. MHI is discussed within the context of development and information processing models. Finally, the sequelae of MHI are reviewed with respect to academic functioning. Methodological problems inherent in studies of MHI are identified and discussed. The studies reviewed here support the conclusion that both the cognitive and emotional consequences of MHI should receive serious evaluation.     

The Effects of Relaxation and Postural Training on External Perception: Improvement of Visual Acuity, Visual Field, and Hearing Acuity

This study examined the effects of muscular relaxation and postural training on external perception using a visual acuity test, a visual field test, and a hearing acuity test. Eighteen undergraduate students were randomly assigned to experimental and control groups. The experimental group underwent muscular relaxation and postural training. Each subject in this group was administered the tests before and after the training. Each subject in the control group carried out the tests before and after participating in a 30-min conversation with the experimenter. On all three tests, the experimental group improved significantly more than the control group.     

A taxonomy of neurobehavioral functions applied to neuropsychological assessment after head injury

Neuropsychological dysfunctions after traumatic brain injury are classified into a taxonomy to plan a comprehensive examination, and organize and report findings for diagnosis and treatment: consciousness, information processing, sensorimotor, neurophysiological, cerebral personality disorders, intelligence, memory, language, stress, psychodynamic, identity and weltanschauung, adaptation, complex adaptive functions, and development of children. Widerange sampling enhances the detection of acute and late-developing dysfunctions, and diagnosis of complex syndromes. Historical, personality, and injury data are components of the assessment. Issues discussed include underestimation of brain injury, malingering, interaction of symptoms, symptom persistence, and noncerebral lesional contributors to impairment after mild head injury.     

Gesturing helps memory encoding in aMCI

Encoding in episodic memory is a step often impaired in patients with amnestic Mild Cognitive Impairment (aMCI). However, procedural memory processes are still relatively preserved. In line with previous research on the enactment effect, we investigated the potential benefit of encoding words combined with imitative gestures on episodic memory. Based on the Grober and Buschke’s free/cued recall procedure, we developed the Symbiosis test in which 13 patients with aMCI and 16 healthy elderly participants learned 32 words belonging to 16 different semantic categories either in a verbal encoding (A) or a bimodal (B; verbal and motor imitation) condition, using a blocked ABBA/BAAB procedure. Overall, memory retrieval was better in healthy participants than in patients with aMCI, and better for cued retrieval in the bimodal encoding (gesture cues) than the verbal encoding (category cues) condition, but there was no interaction effect between group and encoding conditions. These results show that performing concomitant gestures can enhance cued episodic memory retrieval in patients with aMCI and in healthy elderly controls. The Symbiosis test broadens the scope of the enactment effect, from action phrases to isolated words learning in patients with aMCI. Future work should investigate how bimodal encoding provides novel perspectives for memory rehabilitation in patients with aMCI.     

Longitudinal examination of objectively-measured physical activity and sedentary time among children with and without significant movement impairments

BackgroundChildren with Developmental Coordination Disorder (DCD) tend to be less active than typically-developing (TD) children. Current evidence, however, is based on cross-sectional and self-reported activity, and little is known about sedentary time among children with significant movement impairments such as DCD. The current study examines the longitudinal patterns of objectively measured physical activity and sedentary time in children with and without possible DCD (pDCD).MethodsData is from a longitudinal nested case-control study, with 103 participants (n = 60 males ages = 12 and 13 at baseline). Participants averaging ⩽16th percentile on the Movement Assessment Battery for Children were considered having significant movement impairments and pDCD (n = 49). All participants wore accelerometers for seven days.ResultsThere were significant main effects for time (Estimate = −23.98, p < .01) and gender (Estimate = 59.86, p < .05) on total physical activity, and time spent being sedentary (Estimate = 15.58, p < .05). Significant main effects for pDCD (Estimate = −5.38, p < .05) and gender (Estimate = 26.89, p < .01), and time by gender interaction (Estimate = −7.50, p < .05) were found for moderate-to-vigorous physical activity (MVPA). Sedentary time did not differ between children with and without DCD.ConclusionsResults suggest children with pDCD engaged in less MVPA compared to TD children. Consistent patterns of MVPA over time, however, suggest that the divergence in MVPA occurs earlier in childhood. Further longitudinal research following a younger cohort is necessary to identify the specific point that differences in MVPA emerge.     

Visual associations cued recall A Paradigm for Measuring Episodic Memory Decline in Alzheimer’s Disease

Repeated measurements of episodic memory are needed for monitoring amnestic mild cognitive impairment (aMCI) and mild Alzheimer’s disease (AD). Most episodic memory tests may pose a challenge to patients, even when they are in the milder stages of the disease. This cross-sectional study compared floor effects of the Visual Association Test (VAT) and the Rey Auditory Verbal Learning Test (RAVLT) in healthy elderly controls and in patients with aMCI or AD (N = 125). A hierarchical multiple regression analysis was used to examine whether linear or quadratic trends best fitted the data of cognitive test performance across global cognitive impairment. Results showed that VAT total scores decreased linearly across the range of global cognitive impairment, whereas RAVLT total scores showed a quadratic trend, with total scores levelling off for 90% of aMCI patients and 94% of AD patients. We conclude that the VAT shows few if any floor effects in patients with aMCI and mild AD and is therefore a potentially promising cognitive test for monitoring episodic memory impairment.
