AUDITORY/VISUAL PERCEPTION AND MOTOR

DSTP: Differential Screening Test for Processing Gail J. Richard • Jeanane M. Ferre

AGES: 6-0 through 12-11 TESTING TIME: 35 minutes ADMINISTRATION: Individual

The DSTP is the only test of its kind to differentiate among the various levels of audi- tory and language processing and identify areas for referral or further evaluation. It is a screening instrument to help professionals in determining whether additional diagnostic assessment is warranted and the specific areas of focus for further testing. The subtest areas of the DSTP represent the neurological continuum of processing acoustic stimuli. Critical skills are evaluated in three major levels: acoustic, acoustic- linguistic, and linguistic. Test vocabulary was carefully chosen to be within the linguis- tic capabilities of the target population.

INDEXES The five item sets—Phonemes in Isolation, Word Discrimination, Rhyming Sounds (all lan- guage-related), Tonal Patterns, and Environmental Sounds (all non-language-related)—are divided into two auditory scales: the Language Auditory Perception Index (LAPI) and the Nonlanguage Auditory Perception Index (NAPI). The LAPI and NAPI are combined to form the Composite Auditory Perception Index (CAPI), the best measure of auditory perception. The DTAP also has a Background Noise Index (BNI) and a No Background Noise Index (NBNI). The BNI requires the examinee to extract and perceive accurately a target set of sounds from background noise. Chosen as the background or noise field is a set of ambient classroom sounds that are carefully decibel controlled, chosen to enhance the ecological validity of the DTAP BNI as well as its clinical utility. These tasks are embedded in each item set that is routinely administered to each examinee and require substantial contributions from the capabilities of the right and left temporal lobes for accurate performance. COMPLETE DTAP KIT INCLUDES: Examiner’s Manual, 25 Examiner Record Forms, 25 Student Record Forms, and online access to administration audio files.

A carefully targeted measure of auditory perception unconfounded by reasoning.

DTAP: Developmental Test of Auditory Perception Cecil R. Reynolds • Judith K. Voress • Nils A. Pearson

AGES: 6-0 through 18-11 TESTING TIME: 30 minutes ADMINISTRATION: Individual or small group

The DTAP is a battery of five item sets that measure different, but interrelated, aspects of auditory perception. The comprehensive battery is designed to assess auditory perception without invoking higher order verbal reasoning or extensive memory capac- ity. Items are presented via audio files available online to standardize presentation of the language item sets and to include various nonlanguage sounds as well. The DTAP uses a simple response format easily understood and accommodated even by children in the primary grades. Using various language-related as well as non-language-related sounds, the examiner presents pairs of stimuli, and examinees indicate whether the pairs are the same or different. The DTAP can be administered by psychologists, speech–language pathologists, gen- eral and special educators, neuropsychologists, and diagnosticians who are interested in examining the auditory perception status of school-age children.
