The purpose of the study was to explore sensory processing patterns with children ages 5 to 12 years who are diagnosed with two subtypes of ADHD, inattention and hyperactive- impulsive and with children who do not have ADHD. The study delineated children with ADHD from a control group of children without ADHD and how sensory processing issues affect the population with ADHD. The participants were parents or caregivers of children aged 5 to 12 years diagnosed with ADHD and parents or caregivers of children aged 5 to 12 years without a diagnosis of ADHD. The participants totaled 45 with 26 participants in the ADHD group and 19 participants in the non ADHD group. Parents or caregivers completed the SSP Caregiver Questionnaire, the Sensory Processing Measure [SPM], and the Connors Parent Rating Scale-Revised: Short Form. The independent t-test was the statistical procedure used to determine whether the means of the ADHD and non-ADHD groups were statistically different from each other. A Pearson correlation was calculated to measure the degree of association between the children with ADHD and non-ADHD with the types of sensory processing patterns. Finding suggested that children who score high on these ADHD scales have more sensory processing difficulties. Children with hyperactivity ADHD scored a significantly higher mean then children with inattention on an auditory subtest and on a under responsive subtest. Children with inattentive ADHD scored a significantly higher mean than children with hyperactivity on a touch subtest. / Occupational Therapy

Auditory processing is the ability of the brain to manipulate and utilise the neural output of the ear based on the frequency, intensity, and temporal features of the incoming acoustic signal. An auditory processing disorder (APD) is a deficiency in this ability. One category of tests that examine auditory processing ability are the various versions of the "filtered words test" (FWT), whereby a monaural, low-redundancy speech sample is distorted by using filtering to modify its frequency content. Due to the richness of the neural pathways in the auditory system and the redundancy of acoustic information in spoken language, a normal listener is able to recognize speech even when parts of the signal are missing, whereas this ability is often impaired in listeners with APD. One limitation of the various versions of the FWT is that they are carried out using a constant level of low-pass filtering (e.g. a corner frequency of 1000 Hz), which is prone to ceiling and floor effects. The purpose of this study was to counter these effects by modifying the FWT to use a computer-based adaptive procedure, to improve the sensitivity of the test over its constant-level counterparts. The University of Canterbury Monosyllabic Adaptive Speech Test (UC MAST) was performed on 23 normal adults, and 32 normal children (7 to 11 years of age). The child participants also underwent the SCAN-C test for APD in Children (Revised). Findings indicated a significant maturational effect on the UC MAST. Adult participants performed significantly better on the UC MAST in comparison to the child participants. In addition, adult participants performed the UC MAST more reliably than their younger counterparts. No correlation was found between performance on the UC MAST and SCAN-C test. The development of the UC MAST is discussed and the clinical implications of the findings are explored.

Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Anne E. Beamish / The purpose of this research was to develop a mobile sensory garden to help children with Sensory Integration Disorders. Sensory Integration (SI) is how an individual processes sensory information. Issues with sensory integration can lead to behavioral disorders, which can cause difficulties with social-emotional skills, gross motor skills, fine motor skills, play skills, and self-help skills. The goal of the project was to develop a mobile sensory garden to help alleviate or reduce the negative aspects of Sensory Integration Disorders. The research involved qualitative research, projective design, and evaluative research on a mobile sensory cart that was used in an elementary school in Topeka, Kansas. Methods included: interviews, design/build, and observation. The current sensory room was inventoried in Williams Science & Fine Arts Elementary Magnet School in Topeka, Kansas, and the children who used were observed. The faculty at the school, including the principal, teachers whose students use the current sensory room, counselors, and other support faculty, were interviewed. Once the observations were analyzed, a mobile sensory garden cart was designed and built. The new cart was brought to the elementary school and placed in the sensory room. A second phase of observation assessed how the children interacted with the new mobile sensory garden cart. During the second phase of observation the children showed intense interest in the mobile sensory garden cart. Some of this can be attributed to it being a new item in the sensory room. Some of the most popular items included the zen garden, wood slices on the wooden dowel, and the plants. In the second week children transitioned to using both the sensory garden cart and the original items in the sensory room. When an item on the sensory garden cart best suited their needs, that item was chosen and when their needs were best suited by other items in the room then that item was chosen. Overall the mobile sensory garden cart was beneficial to the school and the children. It can be easily replicated and modified to fit the individual needs of the children and school.

Children with central auditory processing disorders (CAPD) have a normal pure-tone audiogram, however, they have difficulty understanding speech in the presence of background noise. The present study examined binaural hearing in normal children and those with possible CAPD. Each subject was administered the SCAN or SCAN-A, screening tests for CAPD, to determine whether they were at risk for CAPD. Participants were then subjected to several monaural and binaural speech tasks, in quiet and noise. Spondee words were utilized in each task, under headphone and soundfield conditions.

Masking Level Difference (MLD) tests are an established component of auditory processing test batteries; however, normative data for these tests vary according to procedure. In this study, forty normal, native-English speaking adults between the ages of 18 and 26 were tested for MLD via a newly developed computer software program using both an adaptive procedure (MLDA) and a Bekesy procedure (MLDB). The results from the two procedures were analyzed for sex differences and compared with each other. For both the MLDA and MLDB, the results showed statistically significant sex differences in the masked thresholds used to obtain the MLD (NoSo and NoSπ), but no significant difference in the calculated MLD value (NoSo - NoSπ). These results suggest that since the MLD was similar for both sexes, the normative data need not be reported separately by sex. The results also showed statistically significant differences between procedures, with the MLDA procedure producing higher MLDs than the MLDB procedure. The MLDA procedure lent itself to a d´ analysis, which could not be determined using MLDB due to the nature of a Bekesy assessment. For MLDA, d´ = 1.4, test sensitivity = 96.4%, and test specificity = 60.3%. The results of this study indicate that MLDA is a better testing procedure due to MLDA's higher MLD average and the statistical data available (d´, and measures of sensitivity and specificity) when using the MLDA procedure.
