Phonological Complexity

Purpose This study examined the performance of Gulf Arabic–speaking children with developmental language disorder (DLD) on a Gulf Arabic nonword repetition (GA-NWR) test and compared it to their age- and language-matched groups. We also investigated the role of syllable length, wordlikeness, and phonological complexity in light of NWR theories. Method A new GA-NWR test was conducted with three groups of Gulf Arabic–speaking children: school-age children with DLD, language-matched controls (LCs), and age-matched controls (ACs). The test consisted of two- and three-syllable words that either had no clusters, medial clusters, final clusters, or medial + final clusters. Results The GA-NWR distinguished between the performance of children with DLD and the LC and AC groups. Results showed significant syllable length, wordlikeness, and phonological complexity effects. Differences between the DLD and typically developing groups were seen in two- and three-syllable nonwords; however, when compared on nonwords with no clusters, children with DLD were not significantly different from the LC group. Conclusions The GA-NWR test differentiated between children with DLD and their ACs and LCs. Findings, therefore, support its clinical utility in this variety of Arabic. Results showed that phonological processing factors, such as phonological complexity, may have stronger effects when compared to syllable length effects.

In the present study, we further examined (see Kamhi & Catts, 1986) the phonological processing abilities of language-impaired (LI) and reading-impaired (RI) children. We also evaluated these children's ability to process spatial information. Subjects were 10 LI, 10 RI, and 10 normal children between the ages of 6:8 and 8:10 years. Each subject was administered eight tasks: four word repetition tasks (monosyllabic, monosyllabic presented in noise, three-item, and multisyllabic), rapid naming, syllable segmentation, paper folding, and form completion. The normal children performed significantly better than both the LI and RI children on all but two tasks: syllable segmentation and repeating words presented in noise. The LI and RI children performed comparably on every task with the exception of the multisyllabic word repetition task. These findings were consistent with those from our previous study (Kamhi & Catts, 1986). The similarities and differences between LI and RI children are discussed.

The Individual

In our previous studies we supported the claim that the motor theory is modulated by task load. Motoric participation in phonological processing increases from speech perception to speech production, with the endpoints of the dorsal stream having changing and complementary weightings for processing: the left inferior frontal gyrus (LIFG) being increasingly relevant and the left superior temporal gyrus (LSTG) being decreasingly relevant. Our previous results for neurostimulation of the LIFG support this model. In this study we investigated whether our claim that the motor theory is modulated by task load holds in (frontal) aphasia. Person(s) with aphasia (PWA) after stroke typically have damage on brain areas responsible for phonological processing. They may present variable patterns of recovery and, consequently, variable strategies of phonological processing. Here these strategies were investigated in two PWA with simultaneous fMRI and tDCS of the LIFG during speech perception and speech production tasks. Anodal tDCS excitation and cathodal tDCS inhibition should increase with the relevance of the target for the task. Cathodal tDCS over a target of low relevance could also induce compensation by the remaining nodes. Responses of PWA to tDCS would further depend on their pattern of recovery. Responses would depend on the responsiveness of the perilesional area, and could be weaker than in controls due to an overall hypoactivation of the cortex. Results suggest that the analysis of motor codes for articulation during phonological processing remains in frontal aphasia and that tDCS is a promising diagnostic tool to investigate the individual processing strategies.
