Global/Local Processing In Incidental Perception Of Hierarchical Structure, Mark S. Mills
Global/Local Processing In Incidental Perception Of Hierarchical Structure, Mark S. Mills
Department of Psychology: Dissertations, Theses, and Student Research
The goal of the current thesis is to provide a framework for investigating and understanding visual processing of hierarchical structure (i.e., local parts nested in global wholes, such as trees nested in forests) under incidental processing conditions—that is, where processing of information at global and local levels is both uninformative (cannot aid task performance) and task-irrelevant (need not be processed to perform the task). To do so, a novel method combining two widely-used paradigms (spatial cueing and compound stimulus paradigms) is used for implicitly probing observers’ perceptual representations over the course of processing. This compound arrow cueing paradigm was used …

We examined the development of racial categorizations of faces spanning the European–East Asian (“White–Asian”) categorical continuum in children between the ages of four and nine as well as adults. We employed a stimulus set that independently varied skin color and other aspects of facial physiognomy, allowing the contribution of each to be assessed independently and in interaction with each other. Results demonstrated substantial development across this age range in children’s ability to draw on both sorts of cue, with over twice as much variance explained by stimulus variation in adults than children. Nonetheless, children were clearly sensitive to both skin …
Focusing On Selection For Fixation, John K. Tsotsos, Calden Wloka, Yulia Kotseruba
Focusing On Selection For Fixation, John K. Tsotsos, Calden Wloka, Yulia Kotseruba
MODVIS Workshop
Building on our presentation at MODVIS 2015, we continue in our quest to discover a functional, computational, explanation of the relationship among visual attention, interpretation of visual stimuli, and eye movements, and how these produce visual behavior. Here, we focus on one component, how selection is accomplished for the next fixation. The popularity of saliency map models drives the inference that this is solved; we suggested otherwise at MODVIS 2015. Here, we provide additional empirical and theoretical arguments. We then develop arguments that a cluster of complementary, conspicuity representations drive selection, modulated by task goals and history, leading to a …
Attention Strongly Modulates Reliability Of Neural Responses To Naturalistic Narrative Stimuli, Jason J. Ki, Simon P. Kelly, Lucas C. Parra
Attention Strongly Modulates Reliability Of Neural Responses To Naturalistic Narrative Stimuli, Jason J. Ki, Simon P. Kelly, Lucas C. Parra
Publications and Research
Attentional engagement is a major determinant of how effectively we gather information through our senses. Alongside the sheer growth in the amount and variety of information content that we are presented with through modern media, there is increased variability in the degree to which we “absorb” that information. Traditional research on attention has illuminated the basic principles of sensory selection to isolated features or locations, but it provides little insight into the neural underpinnings of our attentional engagement with modern naturalistic content. Here, we show inhumansubjects that the reliability of an individual’s neural responses with respect to a larger group …
The Effects Of Changing Attention And Context In An Awake Offline Processing Period On Visual Long-Term Memory, Timothy M. Ellmore, Anna Feng, Kenneth Ng, Luthfunnahar Dewan, James C. Root
The Effects Of Changing Attention And Context In An Awake Offline Processing Period On Visual Long-Term Memory, Timothy M. Ellmore, Anna Feng, Kenneth Ng, Luthfunnahar Dewan, James C. Root
Publications and Research
There is accumulating evidence that sleep as well as awake offline processing is important for the transformation of new experiences into long-term memory (LTM). Yet much remains to be understood about how various cognitive factors influence the efficiency of awake offline processing. In the present study we investigated how changes in attention and context in the immediate period after exposure to new visual information influences LTM consolidation. After presentation of multiple naturalistic scenes within a working memory paradigm, recognition was assessed 30 min and 24 h later in three groups of subjects. One group of subjects engaged in a focused …
