Abstract Two lexical decision experiments were conducted to study the recognition of two-character Chinese monomorphemic and compound words by adult native Chinese readers. In Experiment 1, the words appeared non-spaced, whereas in Experiment 2 a space was inserted between the two characters. An interaction between word type and spacing reflects a trend for spacing to slow down the recognition of monomorphemic words and speed up that of compound words. The word frequency effect was steeper for monomorphemic than compound words. The number of strokes in the first and the second character influenced the recognition time for compound words, but not for monomorphemic words. The results are interpreted in the light of the parallel dual route model of morphological processing. The holistic route is more prevalent in recognizing Chinese monomorphemic, while the morphological decomposition route is more prevalent in processing Chinese compound words.

This chapter describes neurolinguistic aspects of morphology, morphological theory, and especially morphological processing. It briefly mentions the main processing models in the literature and how they deal with morphological issues, i.e. full-listing models (all morphologically related words are listed separately in the lexicon and are processed individually), full-parsing or decompositional models (morphologically related words are not listed in the lexicon but are decomposed into their constituent morphemes, each of which is listed in the lexicon), and hybrid, so-called dual route, models (regular morphologically related words are decomposed, irregular words are listed). The chapter also summarizes some important findings from the literature that bear on neurolinguistic aspects of morphological processing, from both language comprehension and language production, taking into consideration neuropsychological patient studies as well as studies employing neuroimaging methods.

Surface frequency and proficiency modulate visual morphological processing in second language (L2) learners, but less is known about auditory morphological processing. Moreover, working memory affects morphosyntactic processing, but it is unclear whether it also modulates word structure processing. In the present study, Spanish monolinguals and beginner and advanced L2 learners of Spanish completed an auditory lexical decision task in Spanish containing verbs varying in morphological complexity, an individual surface frequency task, and a working memory task. Beginner L2 learners needed more time to process infrequent morphologically complex words, but monolinguals and advanced L2 learners were unaffected by morphological complexity or surface frequency. Also, working memory did not modulate morphological processing. Taken together, the findings suggest a dual-route mechanism at initial stages of L2 acquisition and a whole-word route for Spanish monolinguals and advanced L2 learners. The findings also support the extension of dual-route models to L2 populations and suggest that the selection of a morphological processing route results from linguistic rather than cognitive reasons.

In the current study, we investigated the mechanism of medium-scale traveling ionospheric disturbance (MSTID) triggering spread-F in the low latitude ionosphere using ionosonde observation and Global Navigation Satellite System-Total Electron Content (GNSS-TEC) measurement. We use a series of morphological processing techniques applied to ionograms to retrieve the O-wave traces automatically. The maximum entropy method (MEM) was also utilized to obtain the propagation parameters of MSTID. Although it is widely acknowledged that MSTID is normally accompanied by polarization electric fields which can trigger Rayleigh–Taylor (RT) instability and consequently excite spread-F, our statistical analysis of 13 months of MSTID and spread-F occurrence showed that there is an inverse seasonal occurrence rate between MSTID and spread-F. Thus, we assert that only MSTID with certain properties can trigger spread-F occurrence. We also note that the MSTID at night has a high possibility to trigger spread-F. We assume that this tendency is consistent with the fact that the polarization electric field caused by MSTID is generally the main source of post-midnight F-layer instability. Moreover, after thorough investigation over the azimuth, phase speed, main frequency, and wave number over the South America region, we found that the spread-F has a tendency to be triggered by nighttime MSTID, which is generally characterized by larger ΔTEC amplitudes.
