We investigated whether the accuracy of grammatical morphemes in second language (L2) learners’ writing is associated with usage-based distributional factors. Specifically, we examined L2 English inflectional availability (i.e., token frequency) and contingency frequency relative to other forms same lemma) inflected word form as well formulaicity context which it occurs predictability given sur...

Abstract Children's remarkable ability to generalize beyond the input and resulting overregularizations/ irregularizations provide a platform for discussion of whether morphology learning uses analogy-based, rule-based, or statistical procedures. The present study, testing 115 children (aged 3 10) on an elicited production task, investigated acquisition irregular distribution in Turkish causati...

Sliding Token is a natural reconfiguration problem in which vertices of independent sets are iteratively replaced by neighbors. We develop techniques that may be useful in answering the conjecture that Sliding Token is polynomial-time decidable on bipartite graphs. Along the way, we give efficient algorithms for Sliding Token on bipartite permutation and bipartite distance-hereditary graphs.

We developed courseware for teaching reactive tokens. Reactive tokens are audio or visual signals that structure discourse, and are sent by discourse participants who do not have the floor to those who do. Cultures with much in common sometimes differ markedly in their reactive tokens. Nonnative language learners need to learn how to interpret and convey reactive tokens in order to be perceived...

In a recent note, Marcus (1995) suggests that the rate of overregularization of English irregular plural nouns is not substantively different from that of English irregular past tense verbs. This finding is claimed to be in conflict with the predictions of connectionist models (Plunkett & Marchman, 1991, 1993) which are said to depend solely on the dominance of regular over irregular forms in d...

Without intonation, this causal relation might be interpreted in multiple ways. The speaker might reason, “There would be no parking either on one of those sides”. This conclusion is then based on the argument, “It’s street sweeping day, or something”. This causal relation is interpreted as such by the speaker herself. We can describe such a causal relation as relatively subjective (cf. e.g. Pa...

In a national research project we assessed gender-related communicative patterns in 20 teams from diverse organizations. The sub-sample for this study consisted of two teams with one gender token each: a female token in an industrial team of eleven persons and a male token in a kindergarten team of eight persons. We focused on dominance and support-related behaviour in verbal and nonverbal comm...

Given two independent sets I, J of a graph G, and imagine that a token (coin) is placed at each vertex of I. The Sliding Token problem asks if one could transform I to J via a sequence of elementary steps, where each step requires sliding a token from one vertex to one of its neighbors so that the resulting set of vertices where tokens are placed remains independent. This problem is PSPACE-comp...

We present a design for a Wi-Fi user-authentication token that tunnels data through the SSID field, packet timing, and packet length. Previous attempts to build an online-banking transaction-signing token have been only moderately successful, due in large part to usability problems. Average consumers, especially in the United States, are simply unwilling to transcribe strings of digits from PC ...
