Speakers’ knowledge of alternations is asymmetrical: Evidence from Seoul Korean verb paradigms

This paper investigates whether and how speakers track the relative frequency of different patterns of alternation in the lexicon, by investigating speakers’ behavior when they are faced with unpredictability in allomorph selection. We conducted a wug test on Seoul Korean verb paradigms, testing whether speakers can generalize reliable lexical patterns. The test was performed in two directions. In forward formation test, the pre-vocalic base and pre-consonantal non-base forms were the stimulus and response, respectively, whereas in backward formation test, the stimulus–response relation was switched. The results show patterns approximating statistical patterns in Seoul Korean verb lexicon, thus confirming the lexical frequency matching reported in many previous studies. However, contrary to the conventional assumption, the results of the backward formation test are consistent with lexical frequencies relevant for the forward formation, not backward formation. This observed asymmetry is broadly consistent with the single base hypothesis (Albright 2002a, b, 2005, 2008), in which forward, as opposed to backward formation rules play a privileged role in speakers’ morphological grammar.

Free Variation

In this review, I assess a variety of constraint-based formal frameworks that can treat variable phenomena, such as well-formedness intuitions, outputs in free variation, and lexical frequency-matching. The idea behind this assessment is that data in gradient linguistics fall into natural mathematical patterns, which I call quantitative signatures. The key signatures treated here are the sigmoid curve, going from zero to one probability, and the wug-shaped curve, which combines two or more sigmoids. I argue that these signatures appear repeatedly in linguistics, and I adduce examples from phonology, syntax, semantics, sociolinguistics, phonetics, and language change. I suggest that the ability to generate these signatures is a trait that can help us choose between rival frameworks.

Shock Training

It has been reported, previously, that as escape-from-shock training progressed, Ss increasingly held the lever down. This was true both when shock termination was contingent upon a lever press (press training) and when it was contingent upon release following a press (release training). Moreover, changes in holding were not primarily reflected by changes in response duration but, rather, by shifts in the relative frequencies of responses which were held until the reintroduction of shock, particularly, in press training, escapes which were held until the reintroduction of shock (punished escapes) and, in release training, extra responses which were held until shock returned (punished extras). Finally, the writer had observed some indications that interruption of release training temporarily reduced holding. The present study was undertaken to determine whether the decremental effect of rest on holding is a reliable phenomenon and whether it is obtained with press as well as with release training. Ss were trained at one of four degrees of inter-session time (0, 1, 5, or 10 days of rest) and under either the press or release training procedure. In press training the over-all effect of inter-session time on holding (change in relative frequency of punished escapes) was not significant. The pattern of effects was comparable to those attributed to fatigue or other inhibitory factors which dissipate rapidly during rest. In release training, the effect of inter-session time on holding (change in relative frequency of punished extras) was predominantly decremental. That is, in release training, rest reduced holding. These results are comparable to those commonly attributed to the establishment of competing or interfering stimulus-response relations during rest. A theoretical analysis of response chaining accounted for the interaction of training procedure and inter-session time and indicated, as did supporting data, that delays in training reduced the strength of extra presses, i.e., their initiation, and did not reduce holding per se.

Computer Monitors

The use of computer monitors to provide technology-based written feedback during clinical sessions, referred to as “bug-in-the-eye” (BITi) feedback, recently emerged in the literature with preliminary evidence to support its effectiveness (Carmel, Villatte, Rosenthal, Chalker & Comtois, 2015; Weck et al., 2016). This investigation employed a single-subject, sequential A-B design with two participants to observe the effects of implementing BITi feedback using a smartwatch on the clinical behavior of student clinicians (SCs). Baseline and treatment data on the stimulus-response-consequence (S-R-C) contingency completion rates of SCs were collected using 10 minute segments of recorded therapy sessions. All participants were students enrolled in a clinical practicum experience in a communication disorders and sciences (CDS) program. A celeration line, descriptive statistics, and stability band were used to analyze the data by slope, trend, and variability. Results demonstrated a significant correlative relationship between BITi feedback with a smartwatch and an increase in positive clinical behaviors. Based on qualitative interviews and exit rating scales, SCs reported BITi feedback was noninvasive and minimally distracting. Preliminary evidence suggests BITi feedback with a smartwatch may be an effective tool for providing real-time clinical feedback.
