The present study combines functional magnetic resonance imaging (fMRI) and reaction time (RT) measurements to further elucidate the influence of syllable frequency and complexity on speech motor control processes, i.e., overt reading of pseudowords. Tying in with a recent fMRI-study of our group we focused on the concept of a mental syllabary housing syllable sized ready-made motor plans for high- (HF), but not low-frequency (LF) syllables. The RT-analysis disclosed a frequency effect weakened by a simultaneous complexity effect for HF-syllables. In contrast, the fMRI data revealed no effect of syllable frequency, but point to an impact of syllable structure: Compared with CV-items, syllables with a complex onset (CCV) yielded higher hemodynamic activation in motor “execution” areas (left sensorimotor cortex, right inferior cerebellum), which is at least partially compatible with our previous study. We discuss the role of the syllable in speech motor control.

Endogenous Prostaglandins

Muscles of the stomach possess the ability to synthesize several prostaglandins. These compounds function as local regulatory agents by influencing the motor performance of the muscle cells. In the distal stomach the dominant effect of endogenous prostaglandins is to decrease the amplitude of contractions and decrease the ability of the muscles to respond to excitatory stimuli. Prostaglandins also have a chronotropic role in the distal stomach, and they are responsible for the frequency effect of gastrin pentapeptide. In the proximal stomach prostaglandins have an opposite role; they promote tonic contraction. Because of the diverse effects of prostaglandins, they probably have complicated effects on gastric motility. In general, emptying of solids should be retarded by endogenous prostaglandins, whereas emptying of fluids may be facilitated by these compounds. Overproduction of prostaglandins may produce abnormal motility patterns and affect gastric emptying. A case of gastric pseudoobstruction apparently involving prostaglandins is discussed.

The Right

Abstract The hub role of the right anterior insula (AI) has been emphasized in cognitive neurosciences and been demonstrated to be frequency-dependently organized. However, the functional organization of left AI (LAI) has not been systematically investigated. Here we used 100 unrelated datasets from the Human Connectome Project to study the frequency-dependent organization of LAI along slow 6 to slow 1 bands. The broadband functional connectivity of LAI was similar to previous findings. In slow 6-slow 3 bands, both dorsal and ventral seeds in LAI were correlated to the salience network (SN) and language network (LN) and anti-correlated to the default mode network (DMN). However, these seeds were only correlated to the LAI in slow 2-slow 1 bands. These findings indicate that broadband and narrow band functional connections reflect different functional organizations of the LAI. Furthermore, the dorsal seed had a stronger connection with the LN and anti-correlation with DMN while the ventral seed had a stronger connection within the SN in slow 6-slow 3 bands. In slow 2-slow 1 bands, both seeds had stronger connections with themselves. These observations indicate distinctive functional organizations for the two parts of LAI. Significant frequency effect and frequency by seed interaction were also found, suggesting different frequency characteristics of these two seeds. The functional integration and functional segregation of LDAI and LVAI were further supported by their cognitive associations. The frequency- and seed-dependent functional organizations of LAI may enlighten future clinical and cognitive investigations.

Systematic Effects

The present study investigated the nature of the inhibitory syllable frequency effect, recently reported for normal readers, in a German-speaking dyslexic patient. The reading impairment was characterized as a severe deficit in naming single letters or words in the presence of spared lexical processing of visual word forms. Three visual lexical decision experiments were conducted with the dyslexic patient, an unimpaired control person matched to the patient and a control group: Experiment 1 manipulated the frequency of words and word-initial syllables and demonstrated systematic effects of both factors in normal readers and in the dyslexic patient. The syllable frequency effect was replicated in a second experiment with a more strictly controlled stimulus set. Experiment 3 confirmed the patient’s deficit in activating phonological forms from written words by demonstrating that a pseudohomophone effect as observed in the unimpaired control participants was absent in the dyslexic patient.

Relevant Role

Research has shown that syllables play a relevant role in lexical access in Spanish, a shallow language with a transparent syllabic structure. Syllable frequency has been shown to have an inhibitory effect on visual word recognition in Spanish. However, no study has examined the syllable frequency effect on spoken word recognition. The present study tested the effect of the frequency of the first syllable on recognition of spoken Spanish words. A sample of 45 young adults (33 women, 12 men; M = 20.4, SD = 2.8; college students) performed an auditory lexical decision on 128 Spanish disyllabic words and 128 disyllabic nonwords. Words were selected so that lexical and first syllable frequency were manipulated in a within-subject 2 × 2 design, and six additional independent variables were controlled: token positional frequency of the second syllable, number of phonemes, position of lexical stress, number of phonological neighbors, number of phonological neighbors that have higher frequencies than the word, and acoustical durations measured in milliseconds. Decision latencies and error rates were submitted to linear mixed models analysis. Results showed a typical facilitatory effect of the lexical frequency and, importantly, an inhibitory effect of the first syllable frequency on reaction times and error rates.

Language Exposure

<p>Even though <em>–ing</em> form is acquired earlier based on the natural order hypotheses of L2 morpheme acquisition, it remains difficult for L2 learners to acquire mainly for those who are not frequently exposed to the targeted linguistic feature inputs. A number of investigations were already carried out to find out the frequency effect on the acquisition of verbs as a complement (gerund and infinitive), yet this paper was designed to identify the role of frequency on the acquisition of English <em>–ing</em> form structure by Indonesia L2 learners. Participants consisted of four groups from different semester (1,3,5, and 7). Each semester also indicated various language exposure experienced by L2 learners. Each group comprised 10 participants. Data were collected by employing the writing test to elicit <em>–ing</em> form production including interview and observation. The coding of students’ composition was carried out to determine the correct productions—which were scored to interpret frequency effect on students’ acquisition and their misconceptions in composing a sentence containing –<em>ing</em> forms. The findings revealed that the rate of frequency inputs of –<em>ing</em> form structure accessed by learners fairly contributed to students’ constructional schemas in accordance with the high score. Each word possessed various frequency inputs of distribution which then led them to any deviant production.  In addition, intra-lingual errors were responsible for any misconception perceived by learners (overgeneralization, ignorance of rule restriction, and false concepts hypothesized). </p>

Psycholinguistic Variables

AbstractSeveral studies have been carried out in various languages to explore the role of the main psycholinguistic variables in word naming, mainly in nouns. However, reading of verbs has not been explored to the same extent, despite the differences that have been found between the processing of nouns and verbs. To reduce this research gap, we present here SpaVerb-WN, a megastudy of word naming in Spanish, with response times (RT) for 4562 verbs. RT were obtained from at least 20 healthy adult participants in a reading-aloud task. Several research questions on the role of syllable frequency, word length, neighbourhood, frequency, age of acquisition (AoA), and the novel variable ‘motor content’ in verb naming were also examined. Linear mixed-effects model analyses indicated that (1) RT increase in with increasing word length and with decreasing neighbourhood size, (2) syllable frequency does not show a significant effect on RT, (3) AoA mediates the effect of motor content, with a positive slope of motor content at low AoA scores and a negative slope at high AoA scores, and (4) there is an interaction between word frequency and AoA, in which the AoA effect for low-frequency verbs gradually decreases as frequency increases. The results are discussed in relation to existing evidence and in the context of the consistency of the spelling–sound mappings in Spanish.
