Implementation and evaluation of a Danish test battery for auditory processing disorder in children

Abstract

A Danish APD test battery is now available for clinical use with normative data.

Development of central auditory processes in Polish children and adolescents at the age from 7 to 16 years

“…These findings indicate that the development of dichotic listening in Polish children is completed until 13 years of age. Basically, our outcomes are consistent with previous reports (Kelly, 2007;Mattsson et al, 2018;McDermott et al, 2016;Neijenhuis et al, 2002;Pedersen, Dahl-Hansen, Christensen-Dalsgaard, & Brandt, 2017;Stollman et al, 2004), however, most authors investigated the improvement in listening of dichotic digits in children younger than 12 years arguing that CAP continue to develop until this age and the results of older groups are relatively stable and comparable to those obtained by adults (Keith, 2000;Bellis, 2003;Kelly, 2007;Mattsson et al, 2018;McDermott et al, 2016, Schochat & Musiek, 2006. Our DDT results are comparable with those provided by Neijenhuis et al (2002) in children (aged 7-12 years), adolescents (14-16 years) and adults (in both right and left ear the values in the latter two groups were almost the same but the 12-year-olds still performed worse compared to them).…”

“…1, Table 2). A similar, 10%-difference between 8-and 9-year-olds, was also reported by other authors (Mattsson et al, 2018;Pedersen et al, 2017;Włodarczyk et al, 2019). The course of age-related improvement in the DDT may also reflect developmental changes in divided attention since the measures of both these functions found to be inter-correlated (Stavrinos et al, 2018).…”

“…Comparable with the previous studies (e.g. McDermott et al, 2016;Pedersen et al, 2017) in the youngest groups for both DPT and FPT scores there were large standard deviations which systematically decreased with age. Since the developmental variability of cortical responses is thought to be indicative for sustained attention (Strait, Slater, Abecassis, & Kraus, 2014) and, for example, FPT performance was thought to correlate with academic skills and real-life listening difficulty (Tomlin et al, 2015), the age-related improvement (both higher correctness level and lowered variability of the scores) in children in acoustic pattern recognition may just reflect development of general cognitive functions (attention, working memory).…”

“…Cameron et al, 2016;Kelly, 2007;McDermott et al, 2016). Interestingly, the youngest age groups in our study (7-and 8-year-olds) appear to achieve less correct responses in the left ear DDT compared with their peers from other countries (Cameron et al, 2016;Kelly, 2007;McDermott et al, 2016;Pedersen et al, 2017). This observation could be explained by the fact that, unlike to the test versions used in the aforementioned studies, the digit sequences to repeat in the Polish task, were longer (not only mono-but also bi-syllabic words were included).…”

A European Perspective on Auditory Processing Disorder-Current Knowledge and Future Research Focus

“…Auditory processing evaluation in the clinical setting is largely based on psychoacoustic test batteries of verbal and non-verbal stimuli ( 42 – 50 ) and may be ancillary completed with electrophysiological or objective audiological measures, such as acoustic reflex thresholds, tympanometry, ABR (speech and noise ABR included), or OAEs (suppression included). APD diagnosis (Table 1 ) is a highly demanding time consuming procedure with multidisciplinary information on the client’s profile being essential to test selection.…”
