Bridging Psychometric and Cognitive Models of (General) Intelligence: An Investigation Based on Process Overlap Theory
… attempt to explain the robust findings in cognitive ability testing, such as the positive manifold, from two different perspectives: psychometric or cognitive. Both approaches have their own limitations and are sometimes incompatible with each other. Therefore, contemporary theories of …

Modelling the behaviour of a process control operator under stress
… control operator is proposed. There exists many cognitive models, each of which attempts to model a specific class of human behaviour. One major effect of stress is the cause of errors, both physical and cognitive. In order to model the effects of stress, two cognitive models, a cognitive model …

A laboratory investigation of stress-induced eating behaviour
… theory, and the continuum and new generation cognitive models of BN. The second main aim was to ascertain the existence of information processing and memory biases for scheme-relevant cues unrelated to eating [self-directed ego threat] in the two target populations. Results from these analyses …

Social recovery following first-episode psychosis: the role of negative symptoms and motivation
… reduced motivation (Foussias & Remington, 2010). Cognitive models of negative symptoms propose that expectancy appraisals are involved in the expression and maintenance of negative symptoms (Rector, Beck, & Stolar, 2005; Staring & Van der Gaag, 2010). Theories of motivation (e.g. expectancy-value …

Cognitive Vulnerability to Depression: A Longitudinal Study using Eye-gaze Tracking to Study Attentional Biases in Never Depressed, Non-Relapsed, and Relapsed Individuals
Cognitive models of depression propose that attentional biases are an important cognitive vulnerability in those with a history of depression (e.g., Gotlib & Joormann, 2010; Yiend, 2010; Beck & Haigh, 2014). This study prospectively examined attentional biases in never and previously depressed …

Appraisals of Anomalous Experiences in Need for Care versus Non-Need for Care Groups: Examining the Cognitive Route of Impact of Victimisation Life Events
… are not adversely impacted by such experiences. Cognitive models of psychosis highlight appraisals as key to moving people along the psychosis continuum. Victimisation has also been implicated in both clinical and non-clinical populations. The role of appraisals in providing a cognitive route …

Cognitive Diagnostic Model, a Simulated-Based Study: Understanding Compensatory Reparameterized Unified Model (CRUM)
… and administrators assist students succeed. Cognitive diagnostic modeling (CDM) has the potential to provide valuable information for stakeholders to assist students identify their skill deficiency in specific academic subjects. Cognitive diagnosis models are mainly viewed as a family of …

HiBi: A hierarchical bigram model for associative learning
… people gradually abandon traditional statistical models in favor of deep neural architectures. While effective in learning input-output mappings from two arbitrary distributions, the complex nature of neural models makes them hard to interpret. In this thesis, we introduce a more interpretable …

The role of shame, schemas, cognitions, paranoia and memories in social anxiety following psychosis: a comparison with typical social anxiety
… (2011), it explored factors associated with both cognitive models of social anxiety (Clark & Wells, 1995; Rapee & Heimberg, 1997) and models of social anxiety in psychosis (Birchwood et al., 2006; Lockett, 2011). Methods. The study employed a quantitative cross-sectional design to compare …

Cognitive and Behavioral Model Ensembles for Autonomous Virtual Characters
Cognitive and behavioral models have become popular methods to create autonomous self-animating characters. Creating these models presents the following challenges: (1) Creating a cognitive or behavioral model is a time intensive and complex process that must be done by an expert programmer (2) The …

Improving and Extending Behavioral Animation Through Machine Learning
… three key problems: (1) deliberative behavioral models (i.e., <em>cognitive models</em>) are slow to execute; (2) interactive virtual characters cannot adapt online due to interaction with a human user; (3) programming of behavioral models is a difficult and time-intensive process. This …

Human inspiration for autonomous vehicle tactics
… the strategies and tactics behind them. Human cognitive models and decision making theories were utilized to determine the cognitive processes underneath the decisions as displayed by the human subjects' think aloud reports and surveys.

Remembering the past : multimodal imaging of cortical contributions to episodic retrieval
… framework adopted in this thesis builds upon cognitive models that suggest that episodic retrieval can be decomposed into two classes of computations: (1) recovery processes that serve to reactivate stored memories, making information from a past episode readily available, and (2) control …

Cognitive Modeling and conceptual complexity in translation, multimodal communication, and constructionalization
This PhD dissertation explores cognitive modeling applied to three different areas of analysis: constructionalization, translation, and multimodality. Its aim is to account for the great potential of cognitive models and cognitive operations in the conceptualization and understanding of both …

Sentence processing in aphasia : single case treatment studies
… Assessment of the subjects was guided by models of normal sentence production and comprehension, and involved several new tests which were developed to investigate particular aspects of processing. The assessment phase generated hypotheses about where the processing system was breaking …
