The Influence Of Visual Perspective On The Cognitive Effort Required For Mental Representation, Jeffrey P. Hong

Theses and Dissertations (Comprehensive)

Mental representation is the process by which an individual simulates an event in their mind’s eye. This process is the foundation of the ability to remember the past, engage in prospective thinking, or imagine fictitious scenarios. An individual can mentally represent any event through their own eyes—the first-person perspective or from the viewpoint of an external observer—the third-person perspective. The perspective of representation influences outcomes related to memory, visuospatial processing, affect, social cognition, clinical diagnoses, and language processing. In turn, an individual’s tendency to favour either perspective is shaped by related factors.

The current research consists of four experiments, designed …

Evaluating Neural Networks As Cognitive Models For Learning Quasi-Regularities In Language, Xiaomeng Ma

Dissertations, Theses, and Capstone Projects

Many aspects of language can be categorized as quasi-regular: the relationship between the inputs and outputs is systematic but allows many exceptions. Common domains that contain quasi-regularity include morphological inflection and grapheme-phoneme mapping. How humans process quasi-regularity has been debated for decades. This thesis implemented modern neural network models, transformer models, on two tasks: English past tense inflection and Chinese character naming, to investigate how transformer models perform quasi-regularity tasks. This thesis focuses on investigating to what extent the models' performances can represent human behavior. The results show that the transformers' performance is very similar to human behavior in many …

Derivational Development: Derivational Word Processing In Three English-Speaking Populations, Lisa Suzanne Kemp

LSU Doctoral Dissertations

Native-English speaking adults use morphological decomposition to understand complex words (e.g. farmer becomes farm-er). Whether decomposition is driven by semantic organization is still unclear. It is also unclear whether ESL adults and elementary age children use the same word processing strategies as native speaking adults. This study tested an identical experimental procedure across three English-speaking populations: native speaking adults, non-native speaking adults and elementary age children. The first task tested how readers use base and suffix information in complex words and nonwords when the word featured only a base word, only a suffix, both a base and …

Enhanced Explicit Vocabulary Learning Compared To Implicit Grammar Learning In Adults, Leah Brainin, Marc Joanisse

Western Research Forum

Compared to young children, the language learning process is much more difficult and less successful in adulthood. Little is known about how non-linguistic cognitive processes contribute to these age-dependent differences. We argue that language learning involves both explicit declarative memory processes to learn vocabulary and implicit procedural memory processes to learn grammatical patterns. In this preliminary study, we aimed to quantify the relative contribution of declarative versus procedural learning in adults via an artificial language learning task. Participants ages 18 to 29 heard novel singular and plural words associated with images of common objects. The grammar of the language consisted …

Time, Perspectives, Verbs, And Imagining Events, Jeffrey P. Hong

Theses and Dissertations (Comprehensive)

During the processing of verbs, readers form internal representations of the events described by those verbs. Two key elements in the construction of event representations are temporal information, given by the verbs that describe the represented events, and the visual perspective from which the events are represented. The current study is composed of two experiments aimed at examining the roles these two factors play in event representation. Specifically, the study aimed to determine how temporal information and visual perspective are represented during event imagination.

Experiment 1 investigated the role of temporal information associated with verbs, given by grammatical aspect (GA) …
