Differential Effects Of Stimulus Context In Sensory Processing: Effets Différentiels Du Contexte De Présentation Des Stimuli Sur Les Processus Perceptifs, Yoav Arieh, Lawrence E. Marks Dec 2006

Differential Effects Of Stimulus Context In Sensory Processing: Effets Différentiels Du Contexte De Présentation Des Stimuli Sur Les Processus Perceptifs, Yoav Arieh, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

Stimulus contexts in which different intensity levels are presented to two sensory–perceptual channels can produce differential effects on perception: Perceived magnitudes are depressed in whichever channel received the stronger stimuli. Context differentially can affect loudness at different sound frequencies or perceived length of lines in different spatial orientations. Reported in the hearing, vision, haptic touch, taste, and olfaction, differential context effects (DCEs) are a general property of perceptual processing. Characterizing their functional properties and determining their underlying mechanisms are essential both to fully understanding sensory and perceptual processes and to properly interpreting sensory measurements obtained in applied as well …

Memory For Non-Focal Words, John Jones Dec 2006

Memory For Non-Focal Words, John Jones

Masters Theses & Specialist Projects

In two experiments a modified flanker paradigm was used to simultaneously present a focal word and an incidental non-focal word. The participants' task was to process the focal word in one of two conditions: naming aloud or a conceptual decision (concrete or abstract). The focal and non-focal words were either semantically related or not. Participants were instructed to direct their attention at the focal word. Furthermore, the presentation of the focal word was brief to reduce the possibility of eye movement to the non-focal word. Memory was measured with implicit and explicit memory tests. Evidence was found to suggest implicit …

Relationships In Aging, Cognitive Processes, And Contingency Learning, Sarah Reeder Aug 2006

Relationships In Aging, Cognitive Processes, And Contingency Learning, Sarah Reeder

Masters Theses & Specialist Projects

This study investigated the influence of age, processing speed, working memory,and associative processes on the acquisition of contingency information. Young and older adults completed positive (+.65) and negative (-.65) contingency tasks that measured their ability to discover the relationship between a symptom (e.g., FEVER) and a fictional disease (e.g., OLYALGIA). Both d' scores, i.e., contingency learning, and contingency estimates, i.e., contingency judgment, were examined. Participants were also asked to complete cognitive tasks that measure the constructs of processing speed, working memory resources, associative memory, and associative learning. Structural equation modeling was used to examine the direct and indirect relationships between …

Aging And Associative And Inductive Reasoning Processes In Discrimination Learning, Courtney Ortz Jun 2006

Aging And Associative And Inductive Reasoning Processes In Discrimination Learning, Courtney Ortz

Masters Theses & Specialist Projects

The purpose of this study was to investigate how associative and inductive reasoning processes develop over trials in feature positive (FP) and feature negative (FN) discrimination learning. Younger and older adults completed initial and transfer tasks with either consistent or inconsistent transfer. Participants articulated a rule on every trial. The measure of discrimination learning was the number of trials it took participants to articulate the exact rule. In the initial task, older adults articulated the rule more slowly than younger adults in FP discrimination and took marginally more trials to articulate the rule in FN discrimination than younger adults. Age …

Explorations Of Self: A Philosophical Inquiry, Meredith Rathbun May 2006

Explorations Of Self: A Philosophical Inquiry, Meredith Rathbun

Senior Honors Projects

Asking “Who am I?” seems to be something that everybody ponders. This concept of “I”—what is it? We all have an individual and unique “I”—something that has been with each of us since birth, something that has changed and grown, but also stayed the same in many ways. My question “What is The Self?” is imperative. What is it that experiences life, if not The Self? When a 99-year-old man watches his last sunset, reflecting on his life, what inside of him is doing that reflecting? As you read my ideas on this page, what inside of you is processing …

Methodological Challenges For Identifying And Coding Diverse Knowledge Elements In Interview Data, Victor R. Lee, Moshe Krakowski, Bruce Sherin, Megan Bang, Gregory Dam Jan 2006

Methodological Challenges For Identifying And Coding Diverse Knowledge Elements In Interview Data, Victor R. Lee, Moshe Krakowski, Bruce Sherin, Megan Bang, Gregory Dam

Instructional Technology and Learning Sciences Faculty Publications

This paper, as part of a symposium on the analysis of clinical interview data and the development of a framework for analyzing students' intuitive science knowledge, identifies and discusses methodological challenges encountered when specifying the knowledge elements and resources are invoked dynamically during a clinical interview. Drawing from interviews with middle school students about the seasons and an analysis of knowledge in terms of 'nodes', two classes of problems are identified: those associated with identification of nodes and those associated with their application as codes to a transcript-based data corpus. We posit that these challenges are common ones associated with …

Is Pigmentation Important For Face Recognition? Evidence From Contrast Negation, Richard Russell, Pawan Sinha, Irving Biederman, Marissa Nederhouser Jan 2006

Is Pigmentation Important For Face Recognition? Evidence From Contrast Negation, Richard Russell, Pawan Sinha, Irving Biederman, Marissa Nederhouser

Psychology Faculty Publications

It is extraordinarily difficult to recognize a face in an image with negated contrast, as in a photographic negative. The variation among faces can be partitioned into two general sources: (a) shape and (b) surface reflectance, here termed 'pigmentation'. To determine whether negation differentially affects the processing of shape or pigmentation, we made two sets of faces where the individual faces differed only in shape in one set and only in pigmentation in the other. Surprisingly, matching performance was significantly impaired by contrast negation only when the faces varied in pigmentation. This provides evidence that the perception of pigmentation, not …

Proximity In Context: An Empirically Grounded Computational Model Of Proximity For Processing Topological Spatial Expression., John D. Kelleher, Geert-Jan Kruijff, Fintan Costello Jan 2006

Proximity In Context: An Empirically Grounded Computational Model Of Proximity For Processing Topological Spatial Expression., John D. Kelleher, Geert-Jan Kruijff, Fintan Costello

Conference papers

The paper presents a new model for context-dependent interpretation of linguistic expressions about spatial proximity between objects in a natural scene. The paper discusses novel psycholinguistic experimental data that tests and verifies the model. The model has been implemented, and enables a conversational robot to identify objects in a scene through topological spatial relations (e.g. ''X near Y''). The model can help motivate the choice between topological and projective prepositions.
