In unidimensional absolute identification tasks, participants identify stimuli that vary along a single dimension. Performance is surprisingly poor compared with discrimination of the same stimuli. Existing models assume that identification is achieved using long-term representations of absolute magnitudes. The authors propose an alternative relative judgment model (RJM) in which the elemental ...

This paper concerns the improvements of NO2 forecast due to satellite data assimilation. The Ozone Monitoring Instrument (OMI) aboard NASA Aura satellite provides observations of NO2 columns for air quality study. These satellite observations are assimilated, with the optimal-interpolation method, in an air quality model from Polyphemus, in order to improve NO2 forecasts in Europe. Good consist...

This study tests whether potential differences in the perceptual robustness of speech sounds influence continuous-speech processes. Two phoneme-monitoring experiments examined place assimilation in Korean. In Experiment 1, Koreans monitored for targets which were either labials (/p,m/) or alveolars (/t,n/), and which were either unassimilated or assimilated to a following /k/ in two-word uttera...

The dynamics of spoken word recognition are acutely sensitive to competition among similar-sounding words. Here, we take advantage of this sensitivity to examine the manner in which native Italian speakers who are late learners of English perceive English vowels. Native Italian speakers and native English speakers listened to recordings of naturally produced words (”pin,” ”pen,” and ”pan”) and ...

5 This paper details a strategy for modifying the source code of a complex model so that the 6 model may be used in a data assimilation context, and gives the standards for implementing a data 7 assimilation code to use such a model. The strategy relies on keeping the model separate from any 8 data assimilation code, and coupling the two through the use of Message Passing Interface (MPI) 9 func...

We will argue that the beginnings of words are perceptual “islands of reliability” in connected speech, and that their perceptual and temporal properties allow them to drive critical aspects of spoken word recognition including lexical segmentation. This argument rests on three generalizations derived from research in speech science, phonology, and psycholinguistics. We suggest that word onsets...

A variety of data assimilation approaches have been applied to enhance modelling capability and accuracy using observations from different sources. The algorithms have varying degrees of complexity of implementation, and they improve model results with varying degrees of success. Very little work has been carried out on comparing the implementation of different data assimilation algorithms usin...
