How much information is maintained at each of these different levels, and for how long, remains an open question (see, e.g., Bicknell et al., under review; Dahan, 2010), but it seems fair to assume that maintenance of lower level information within the internal representation of context is shorter-lived than higher level information. This literature also highlights the fact that, because language processing is highly interactive, with extensive communication across representational levels during processing (Elman, Hare, McRae, 2004; McClelland Rumelhart, 1981; Rumelhart McClelland, 1982), a comprehender can use many of these different types of information, encoded within her internal representation of context, to facilitate the processing of incoming information at almost any other level of representation (see Altmann Steedman, 1988; Crain Steedman, 1985; Tanenhaus Trueswell, 1995, for reviews and discussion). We next consider the computational implications of this type of interactivity for understanding the role of prediction in language comprehension. Computational insights In the probabilistic models of parsing we considered in section 1, the aim of the parser was to infer the structure of the sentence that was being communicated. This structure was conceptualized as generating words or word sequences. Several other generative probabilistic models of language have attempted to model inference at different levels and types of representation. For example, phonetic PM01183 dose categories can be understood as generating phonetic cues (Clayards et al., 2008; Feldman et al., 2009; Kleinschmidt Jaeger, 2015; Sonderegger Yu, 2010), while semantic categories (Kemp Tenenbaum, 2008) or topics (Griffiths, Steyvers, Tenenbaum, 2007; Qian Jaeger, 2011) can be understood as generating words. One simplifying feature of all these models is that they each generate just one type of input (although see Brandl, Wrede, Joublin, Goerick, 2008; Feldman, Griffiths, Goldwater, Morgan, 2013; Kwiatkowski, Goldwater, Zettlemoyer, Steedman, 2012, for exceptions in the developmental literature).

One Lasalocid (sodium) biological activity participant only spent 60 a month on alcohol and received other drugs in exchange for letting people use his apartment. Even though the amount spent on alcohol was small, the participant’s alcohol use resulted in his discharge from methadone treatment, after which he relapsed on heroin and had subsequent drug-related problems. Another participant reported receiving cocaine in return for helping drug dealers “run customers.” This participant had a long history of legal problems, hospitalizations, and social conflict associated with his drug use and was taking a large risk by working for drug dealers.

Although the threshold criterion to classify children as stuttering or normally fluent based on frequency of their disfluencies potentially can be set anywhere along the continuous scale of disfluency frequency, in the present study we selected what is known to be a "strict approach" (Swets, 1992). This approach sets a criterion that yields few false positive classifications (i.e., classifying someone as a CWS when, in fact, he or she is normally fluent). Hence we set our criterion to yield false positive classifications at .05 (similar to hypothesis testing procedures in which alpha is set to .05 or less). Thus, with specificity of .95, the 7 non-stuttered disfluencies criterion was identified as a threshold for CWS classification. The area under the ROC curve, a measure of strength of predictive capacity of the model over all cut points, for non-stuttered disfluencies was .61. This was better than chance (.50) but far from perfect (1.00). This indicated that the model fits moderately well and has fair discriminatory ability (Petrie Sabin, 2009), however the sensitivity of this model is relatively low (11 ). The sensitivity pecificity analysis for nonstuttered disfluencies is presented in Table 6. This table shows the trade-off between sensitivity and specificity. For example, a cut point of 10 non-stuttered disfluencies produces high specificity (99 ) but low sensitivity (2 ). The same approach was adopted for sensitivity pecificity analysis for number of total disfluencies. With the specificity criterion set at .95 (yielding false positive classifications on the order of .05), 8 total disfluencies was identified as a threshold for CWS classification. The area under the ROC curve for total disfluencies was .958, suggesting a very strong discriminatory ability at almost any cutting score.

DISCUSSION Characterizing sensor-charge movement in voltage-sensitive proteins provides a host of important information on protein function, including operating voltage range and maximum charge moved (Qmax). The latter metric aids in quantifying protein content within the membrane, and our data indicate that prestin may be present at densities higher than the long-held estimates (26,36). For over a decade, chloride has been believed to be a key player in prestin function (13?6), influencing the quantity of measured sensor charge. However, our new data point to a role of chloride in controlling prestin kinetics and not in limiting the quantity of charge movement. Indeed, we previously showed that the maximum OHC eM magnitude, which is expected to correspond to the charge moved, since eM is voltagedriven, is little affected by chloride (18). Does chloride underlie prestin’s voltage-driven charge movement? Zheng et al. (7) identified the OHC molecular motor as the fifth member of the mammalian SLC26 family of anion exchangers, of which 10 members have been identified (5,37). These anion exchangers facilitate the transmembrane movements of monovalent and divalent anions; however, prestin’s transport capabilities are controversial, with some studies showing transport capabilities and others not (38?3). It is interesting to note that the influence of Necrosulfonamide site anions on NLC had been observed before the identification of prestin. For example, lipophilic anions, but not cations, were shown to influence OHC eM and NLC (44), and it has been known since the mid 1990s that the anion salicylate blocks NLC and eM, working on the intracellular aspect of the OHC (45,46). Notwithstanding the controversy of anion transport, the existence of voltage-dependent displacement currents, or NLC, has been taken to indicate an evolutionary change that enables eM, since SLC26a5’s closest mammalian homolog, SLC26a6, lacks this capability, as assessed by standard high-frequency admittance techniques (13). Whether other SLC26 family members actually possess NLC is a subject for future investigation, since our data indicate that we must now consider the occurrence of charge movements that are slower than typically expected. Should other family members possess slow voltage-sensor charge movements,.Model at 140 mM and 1 mM chloride, respectively. The stimulus protocol and analysis were the same as the biophysical measures. Note the similarity to the biophysical data.
