The needs for precisely estimating a student's academic performance have been emphasized with an increasing amount of attention paid to Intelligent Tutoring System (ITS). However, since labels for academic performance, such as test scores, are collected from outside of ITS, obtaining the labels is costly, leading to label-scarcity problem which…

The ability to spell correctly is a fundamental skill for participating in society and engaging in professional work. In the German language, the capitalization of nouns and proper names presents major difficulties for both native and nonnative learners, since the definition of what is a noun varies according to one's linguistic perspective. In…

The so-called depth charge sentences (e.g., "no head injury is too trivial to be ignored") were investigated in a comprehension experiment measuring both whether participants understood the stimuli and how certain they were of their interpretation. The experiment revealed that three factors influence the difficulty of depth charge type…

Salience influences grammatical structure during production in a language-dependent manner because different languages afford different options to satisfy preferences. During production, speakers may always try to satisfy all syntactic encoding preferences (e.g., salient entities to be mentioned early, themes to be assigned the syntactic function…

In a touch-screen paradigm, we recorded 3- to 7-year-olds' (N = 108) accuracy and response times (RTs) to assess their comprehension of 2-clause sentences containing "before" and "after". Children were influenced by order: performance was most accurate when the presentation order of the 2 clauses matched the chronological order…

Nowadays, machine learning techniques are being used in several Natural Language Processing (NLP) tasks such as Opinion Mining (OM). OM is used to analyse and determine the affective orientation of texts. Usually, OM approaches use affective dictionaries in order to conduct sentiment analysis. These lexicons are labeled manually with affective…

AutoTutor uses conversational intelligent agents in learning environments. One of the major challenges in developing AutoTutor applications is to assess students' natural language answers to AutoTutor questions. We investigated an AutoTutor dataset with 3358 student answers to 49 AutoTutor questions. In comparisons with human ratings, we found…

Speakers typically design definite referring expressions to uniquely identify the intended referent with respect to the alternatives in the referential context, and addressees interpret these expressions with respect to the contextual alternatives. Although it is clear that the relevant context includes entities in the immediate context, less…

This paper investigates the interpretation that Italian-speaking children and adults assign to negative sentences with disjunction and negative sentences with conjunction. The aim of the study was to determine whether children and adults assign the same interpretation to these types of sentences. The Semantic Subset Principle (SSP) (Crain et al.,…

A number of new psycholinguistic variables has been proposed during the last years within embodied cognition framework: modality experience rating (i.e., relationship between words and images of a particular perceptive modality--visual, auditory, haptic etc.), manipulability (the necessity for an object to interact with human hands in order to…

Learning new vocabulary from context typically requires multiple encounters during which word meaning can be retrieved from memory or inferred from context. We compared the effect of memory retrieval and context inferences on short- and long-term retention in three experiments. Participants studied novel words and then practiced the words either…

With its international constituency, the Seventh-day Adventist Church has a large a membership that primarily comprises non-native English speakers. Students have had challenges in understanding and appreciating the writings of one of the church's co-founders, Ellen White. The purpose of this study was to analyze the Testimonies for the Church and…

Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia, accounts for an estimated 60 percent to 80 percent of cases. AD has two subtypes: Early-onset and Late-onset Alzheimer's disease. Both types are characterized by a decline in memory, problem-solving and other cognitive skills that affect a person's…

Two experiments are presented that explore online counterfactual processing in autism spectrum disorder (ASD) using eye-tracking. Participants' eye movements were tracked while they read factual and counterfactual sentences in an anomaly detection task. In Experiment 1, the sentences depicted everyday counterfactual situations (e.g., "If…

A critical task for tutors is to provide learners with suitable reading materials in terms of difficulty. The challenge of this endeavor is increased by students' individual variability and the multiple levels in which complexity can vary, thus arguing for the necessity of automated systems to support teachers. This chapter describes…
