Scalar inference, the process by which we infer meanings stronger than what was explicitly said, has long been a central topic of investigation in theoretical semantics-pragmatics, as well as in psycholinguistics. Upon encountering the sentence "Mary ate some of the deep dish", for instance, hearers regularly compute the pragmatic…

When you look at an image, what do you see? What does the image say to you? What do you think about? What meaning do you infer? These questions may blur together, but they can be expanded individually and uniquely into a multitude of responses. Your initial thoughts are yours. You are silently debating meaning within yourself. If I interject a new…

A considerable amount of research has emerged in recent years concerning second language (L2) learner sensitivity to various information types. From this, Clahsen and Felser proposed the Shallow Structure Hypothesis (SSH) to account for increased learner sensitivity to certain kinds of non-structural (e.g., contextual, discoursal, semantic, and…

Notions of accessibility bring to question the perceived deficits in narrative comprehension for autistic people. This deficit has been positioned as having a cognitive processing disposition towards local coherence, rather than global coherence. Rather than a unitary deficit in the individual, reduced performance on inferential narrative…

This mixed methods study investigates the effect of cultural and sociolinguistic textures of talk on authentic discussion patterns and whether reading comprehension and inferencing are affected in an online booktalk environment with adolescents. The research will also investigate the contextual features of the classroom community to be studied to…

Choosing specific implementational details is one of the most important aspects of creating and evaluating a model. In order to properly model cognitive processes, choices for these details must be made based on empirical research. Unfortunately, modelers are often forced to make decisions in the absence of relevant data. My work investigates the…

Purpose: The goal of the current research study was to advance our knowledge of cognitive-communicative disorders following traumatic brain injury (TBI) by identifying the cognitive and communicative processes underlying narrative discourse ability. The study (1) examined the role of working memory (WM) and inferencing in narrative discourse, (2)…

Insects are the most abundant and diverse group of animals on Earth. Though as a group they do far more ecological good than harm, previous studies have shown that human attitudes toward insects are mainly negative. Attitudes have affective (emotions) and cognitive (beliefs, mental representations) components that interact to influence behavior.…

This study compared an expert-based cognitive model of domain mastery with student-based cognitive models of task performance for Integrated Algebra. Interpretations of student test results are limited by experts' hypotheses of how students interact with the items. In reality, the cognitive processes that students use to solve each item may be…

The most important information conveyed by language is often contained not in the utterance itself, but in the interaction between the utterance and the comprehender's knowledge of the world and the current situation. This dissertation uses psycholinguistic methods to explore the effects of a common type of inference--causal inference--on language…

The difficulties introductory statistics students have with formal statistical inference are well known in the field of statistics education. "Informal" statistical inference has been studied as a means to introduce inferential reasoning well before and without the formalities of formal statistical inference. This mixed methods study…

This qualitative study examines children's comprehension of conventional, wordless, and postmodern picturebooks. The research question was: How do children construct meaning of conventional, wordless, and postmodern picturebooks? More specific questions were: 1) What are the reading strategies that children use as they make sense of…

Rate of change is an important concept for students to study, and little is known about the ways in which secondary students make sense of rate of change. In this qualitative study I examined how four high school students who have not taken calculus reasoned about changing quantities when interacting with mathematical tasks involving multiple…

The testing effect, where retrieval practice aids performance on later tests, may be a powerful tool for improving learning and retention. Three experiments test the potentials and limitations of retrieval practice for retention and comprehension of the content of science texts. Experiment 1 demonstrated that cued recall of paragraphs, but not…

Students with learning disabilities (LD) often struggle with reading comprehension (Shaywitz, 2003), even after attaining basic decoding skills. Similar proportions of students with LD have also been found to differ from their typical peers in some aspect of social adjustment (Kavale & Forness, 1996). Yet there is very little known about the…
