Perceptual Learning Of Object Shape
… of familiar shapes. We used a paradigm of perceptual learning during visual search to explore what features human observers use to identify objects. Human subjects were trained to search for a target object embedded in an array of distractors, until their performance improved from chance …

Effects of Resting State On Perceptual Learning
… in humans have demonstrated that improvements in perceptual learning tasks occur following daytime rests. The neural correlates of how rest influences subsequent sensory processing during these tasks remain unclear. One possible neural mechanism that may underlie this behavioral improvement is …

Confidence and feedback in visual perceptual learning
The classical view that perceptual learning is highly specific to the stimulus properties used during training is being challenged by accumulating evidence of transfer under specific conditions. Perceptual learning in the adult brain may result from an element of cortical reorganisation at a …

Perceptual learning of context-sensitive phonetic detail
… this shortcoming, this thesis investigated perceptual learning of systematic phonetic detail relating to higher levels of linguistic structure, including prosodic, grammatical and morphological contexts. Furthermore, in contrast to many previous studies, this research used relatively natural …

Measurements of Malleable Visual Mechanisms Through High-resolution fMRI and Perceptual Learning
… sensory eye dominance could be altered using a perceptual learning technique. This study used orthogonal gratings during binocular rivalry to influence the temporal dynamics of sensory eye dominance through repeated training. Participants completed 12 days of a task meant to increase …

The Role of Facial Gestural Information in Supporting Perceptual Learning of Degraded Speech
… is remarkably successful, due in part to perceptual learning. Previous research has demonstrated more rapid perceptual learning of acoustically-degraded speech when listeners are given the opportunity to map the linguistic content of utterances, presented in clear auditory form, onto the …

Perceptual Learning, Long-Range Horizontal Connections And Top-Down Influences In Primary Visual Cortex
… A final set of experiments showed that prior to learning the same contour integration task, the responses did not contain any information about the stimulus position, that the information in the response increased in parallel with the animals performance during learning, and that the enhanced …

A Study in Texture Segmentation: Investigating the Role of Template Retuning in Perceptual Learning
… are recognized in observers performing perceptual tasks that may be the product of practice or the observer's familiarity with the task. These differences suggest the possibility of perceptual learning (PL), which could be linked to first-order information. The purpose of the present …

Roles of reward, memory, and cognitive control on visual perceptual learning and decision-making
A prevailing hypothesis of visual perceptual learning (VPL) is that for a feature to be learned, focused attention must be directed to that feature. Along these lines, top-down, task-related factors are also required for such learning to take place. The first aim of this thesis was to challenge …

Prenatal Perceptual Experience and Postnatal Perceptual Preferences: Evidence for Attentional-Bias in Perceptual Learning
… stimulation can interfere with prenatal perceptual learning. However, the nature and extent of this interference is not well understood. This study further assessed this issue by exposing three groups of bobwhite quail embryos to (a) no unusual prenatal stimulation, (b) a bobwhite …

Relationship among perceptual learning styles, productive vocabulary, and textbooks in English as a foreign language learning
Perceptual learning styles have been widely investigated in English as a Foreign Language (EFL). However, less attention has been paid to productive vocabulary and the perceptual activities and words included in English Language Teaching (ELT) textbooks. To our knowledge, the relation among these …

The Role of Parvalbumin Interneurons in Mouse Primary Visual Cortex during Visual Discrimination and Perceptual Learning
… roles in balancing cortical circuit activity and learning (Xu et al., 2010). PV cells are suggested to mediate feedforward inhibition and control gain modulation (Markram et al., 2004; Tremblay et al., 2016). Although increasing their activity may improve discrimination (Lee et al., 2012), …

A Study of the Perceptual Learning Styles of Fifth and Sixth Grade Remedial and Non-Remedial Math Students
… if there was a significant difference in the perceptual learning styles of remedial and non-remedial mathematics students. A further purpose was to determine if there were any combinations of learnings style variables and mathematics subtest scores that would serve as significant predictors of …

Perceptual Learning Style Preferences and Their Relationship to Language Learning Strategies in Adult Students of English as a Second Language
… have focused on different aspects of cognitive learning style--an individual's preferred means of processing information. Within the cognitive domain, perceptual learning style emerges as a neglected, yet significant factor in second language acquisition. Through the learner's perceptual …

Perceptual learning in foveal and peripheral contrast discrimination: exploring the effects of stimuli on learning and the effects of learning on spatial vision
… in the normal periphery and in amblyopia. Perceptual learning has been shown to improve spatial vision in amblyopia but has not previously been employed to investigate crowding in amblyopia. The purpose of this work was to investigate the effect of surrounding stimuli parameters on crowding …

Understanding the Impact of Differentiation and Unitization on the Perceptual Features Learned During Category Training
Perceptual representations are a foundational aspect of all cognitive processes that involve input from the external environment. Yet there is ample evidence that these perceptual representations are altered by experience in systematic ways. This work focuses on understanding how perceptual …

The role of perceptual learning in accounting for the own-race bias, the inversion effect, and the distinctiveness effect in recognition memory for faces from a developmental perspective
The rated distinctiveness of a face, the orientation in which a face is seen and the race of the face, are all factors that are known to affect subsequent recognition of faces. These three factors are known as the distinctiveness effect, the orientation effect and the own-race bias. The main …
