Learning and applying model-based visual context
I believe that context's ability to reduce the ambiguity of an input signal makes it a vital constraint for understanding the real world. I specifically examine the role of context in vision and how a model-based approach can aid visual search and recognition. Through the implementation of a system …

Spontaneous speech recognition using visual context-aware language models
… Fuse that performs speech understanding for visual object selection. An experimental task was created in which people were asked to refer, using speech alone, to objects arranged on a table top. During training, Fuse acquires a grammar and vocabulary from a "show-and-tell" procedure in which …

Expectation-based comprehension of linguistic input: facilitation from visual context
Context fundamentally shapes real-time human language processing, creating linguistic expectations that drive efficient processing and accurate disambiguation (Kuperberg and Jaeger, 2016). In naturalistic language understanding, the visual scene often provides crucial context (Ferreira et al., …

Human Visual Navigation: Effects of Visual Context, Navigation Mode, and Gender
Abstract This thesis extends research on human visual path integration using optic flow cues. In three experiments, a large-scale path-completion task was contextualised within highly-textured authentic virtual environments. Real-world navigational experience was further simulated, through the …

Monitoring eye movements to uncover the role of visual context in the access to verb-complement information during sentence comprehension
This study examined the role of sentence and visual context in the access to verb-complement information, using an eye-tracker paradigm. Two sets of sentences were contrasted, a highly constraining causative construction in which there was a close conceptual relation between the verb and its direct …

Language Modeling from Visually Grounded Speech
… fully leveraging multimodal inputs, particularly visual context, remains underexplored. This thesis addresses this gap by developing novel language modeling techniques directly from visually grounded speech. We first introduce the Audio-Visual Neural Syntax Learner (AV-NSL), an unsupervised parser …

Choosing referring expressions
… the referent’s salience in the prior linguistic context, but much less is known about how non-linguistic context affects the referent’s salience and the choice of expression. Recent research has suggested that the referent’s non-linguistic salience has no effect on the choice of pronouns and …

Program Comprehension Through Sonification
… in part to clutter in the software developer's visual environment and the need for frequent visual context changes. Non-speech sound has been shown to be useful in understanding the behavior of a program as it is running. Aims: This thesis explores whether using sound to help understand the …

Visual Analytics and Interactive Machine Learning for Human Brain Data
This study mainly focuses on applying visualization techniques on human brain data for data exploration, quality control, and hypothesis discovery. It mainly consists of two parts: multi-modal data visualization and interactive machine learning. For multi-modal data visualization, a major challenge …

Competing Cues in Ambiguous Speech Comprehension: The Role of Visual Competition and Linguistic Context
… to quickly resolve ambiguity, drawing on both context and word-meaning frequency information to correctly comprehend words with multiple meanings. While it is well established that more common meanings are accessed more easily and that strong context supports disambiguation, less is known about …

On the Screen, In the Mind: An ERP Investigation into the Interaction Between Visuo-Spatial Information and Spatial Language During On-Line Processing
… <p>Results indicated that linguistic and visual context impacted ERPs to words in these phrases. Beginning with linguistic context, all prepositional phrases yielded negative slow-wave activity in parietal and occipital sites, while conjunction phrases did not. Because this negativity is …

The effects of learning schedules and external visual information on implicit sensorimotor adaptation of upper limb movements.
… motor adaptation, and its sensitivity to visual context cues. We first demonstrate that the extent of implicit adaptation depends on how motor errors are introduced during a training paradigm. We find the largest extents of implicit adaptation when participants can adapt to small but …

The Effect of Celebrity Gaze-Cueing on Binary Choice Decision Making

Efficient language processing: the role of memory and visuo-spatial context
… al., 2014) and pragmatic (Sedivy et al., 1999) contextual information can be rapidly integrated during the comprehension process. In this dissertation, I explored the use of this information during on-line language processing and how it is supported by learning and memory mechanisms. In Chapter …

A computational model to connect gestalt perception and natural language
… a computational model that connects gestalt visual perception and language. The model grounds the meaning of natural language words and phrases in terms of the perceptual properties of visually salient groups. We focus on the semantics of a class of words that we call conceptual aggregates …

Target-directed Locomotion: A Critique Of The Short-term Memory For Spatial Locations Proposed By Thomson
… second part of the thesis examined the role of visual context in the control of locomotor accuracy. Being able to see the target led to highly accurate locomotion. Performance was less accurate when subjects had feedback of the area surrounding the target, but not of the target itself. …
