Perception and perceptual memory play crucial roles in fear generalization, yet their dynamic interaction remains understudied. This research (N = 80) explored their relationship through a classical differential conditioning experiment. Results revealed that while fear context perception fluctuates over time with a drift effect, perceptual memory…

Evidence accumulation models have enabled strong advances in our understanding of decision-making, yet their application to examining learning has not been common. Using data from participants completing a dynamic random dot-motion direction discrimination task across four days, we characterized alterations in two components of perceptual…

Categorization researchers have long debated the possibility of multiple category-learning systems. The need persists for paradigms that dissociate explicit-declarative category-learning processes (featuring verbalizable category rules) from implicit-procedural processes (featuring stimulus-response associations lying beneath declarative…

According to an aptitude-treatment interaction experiment (Lehmann et al., "Metacognition and Learning, 11," 89-105, 2016, N = 47, published in "Metacognition and Learning"), perceptually disfluent texts facilitated retention and comprehension performance (but not transfer performance) only for learners with higher working…

Introduction: The introduction of competence-based approach in international educational official documents has been justified by the development of more active learning methods to respond to social and equality challenges for students. Competence is defined as a situated activity composed of several components, especially knowledge built in…

The aim of this dissertation is to investigate the mechanisms involved in phonetic learning of an unfamiliar accent, focusing on understanding what processes underlie changes to phonetic category structure, how such learning affects subsequent online lexical processing, and whether the same mechanisms that underlie learning for a single speaker…

The role of top-down control in divergent creativity remains heavily debated. An outstanding question about the state dynamics of creativity concerns acute shifts between heightened and lowered creative states. Particularly, do transitions between creative states incur a "switch cost" as observed in other domains of cognition? Prior…

Teachers are confronted with multiple stimuli during instruction. To teach responsively, they must be able to identify and address classroom incidents that are critical for student learning. In the literature, the term "noticing" is used to refer to teachers' perception and interpretation of such incidents, as well as the associated…

The role of awareness has been under investigation in second language (L2) acquisition research for many years. Williams' study (2005) has attracted particular interest and has been actively reexamined from a variety of perspectives, and the replications and extensions of the research currently form a research horizon on the intersection of…

The research aimed to construct an instructional model for creative writing for Mattayomsueksa Three students (Grade 9), to develop the model according to a criterion of 80/80, and to examine the results of the model in use. The research methodology consisted of three phases: phase one studied the current states, problems and needs for teaching…

Young children are able to categorize animals on the basis of unobservable features such as shared biological properties (e.g., bones). For the most part, children learn about these properties through explicit verbalizations from others. The present study examined how such input impacts children's learning about the properties of categories. In a…

This dissertation explores the processes that drive perceptual adaptation to variation in speech by examining how sources of prediction and uncertainty modulate perceptual learning processes. In particular, we examined how the perceptual system leverages different types of information during adaptation, varying in the degree to which they predict…

Prior research shows that representational competencies that enable students to use graphical representations to reason and solve tasks is key to learning in many science, technology, engineering, and mathematics domains. We focus on two types of representational competencies: (1) "sense making" of connections by verbally explaining how…

Prior research shows that representational competencies that enable students to use graphical representations to reason and solve tasks is key to learning in many science, technology, engineering, and mathematics (STEM) domains. We focus on two types of representational competencies: (1) "sense making" of connections by verbally…

We examined how feedback delay and stimulus offset timing affected declarative, rule-based and procedural, information-integration category-learning. We predicted that small feedback delays of several hundred milliseconds would lead to the best information-integration learning based on a highly regarded neurobiological model of learning in the…
