Concepts, Perception And The Dual Process Theories Of Mind, Marcello Frixione, Antonio Lieto

Baltic International Yearbook of Cognition, Logic and Communication

In this article we argue that the problem of the relationships between concepts and perception in cognitive science is blurred by the fact that the very notion of concept is rather confused. Since it is not always clear exactly what concepts are, it is not easy to say, for example, whether and in what measure concept possession involves entertaining and manipulating perceptual representations, whether concepts are entirely different from perceptual representations, and so on. As a paradigmatic example of this state of affairs, we will start by taking into consideration the distinction between conceptual and nonconceptual content. The analysis of …

Change Detection In Rhesus Monkeys And Humans, Deepna T. Devkar, Deepna T. Devkar

Dissertations & Theses (Open Access)

Visual working memory (VWM) is the temporary retention of visual information and a key component of cognitive processing. The classical paradigm for studying VWM and its encoding limitations has been change detection. Early work focused on how many items could be stored in VWM, leading to the popular theory that humans could remember no more than 4±1 items. More recently, proposals have suggested that VWM is a noisy, continuous resource distributed across virtually all items in the visual field, resulting in diminished memory quality rather than limited quantity. This debate about the nature of VWM has predominantly been studied with …

Who Or What Should I Be Like? The Self-Assessment Of Sexual Desire, Caroline Maykut

UNLV Theses, Dissertations, Professional Papers, and Capstones

The construct of sexual desire has been notoriously difficult to capture and measure, in part as a function of questionable methods of sexual desire assessment. Due to problems finding an accurate, objective marker of sexual desire, research has relied on self-report. One notable difficulty with self-reported desire assessment is the lack of information on the context in which these assessments are made. The only available data focuses on relative assessment of sexual desire within couples, and ignores broader social and cultural contexts. The present study investigated men and women's perception of sexual desire discrepancies between themselves and other people and …

Blue Is In The Eye Of The Beholder: A Cross Cultural Study On Color Perception And Memory, Mark Douglas Lowry

USF Tampa Graduate Theses and Dissertations

According the linguistic relativity hypothesis, the language one speaks affects how one thinks. Because languages differ in how they categorize color, linguistic relativity has often been tested by conducting experiments on color perception and memory. This study examines the linguistic relativity hypothesis using ecologically valid stimuli: pictures of eyes. Because Russian-speakers are more likely to describe blue/grey eyes as grey, whereas English speakers are more likely to describe them as blue, English and Russian participants were asked to match the overall color of blue eyes to a color scale. There were three conditions. In the first condition (perception), participants saw …

The Perception Of The Economy Influencing Public Opinion On Immigration Policy, Jeff Sanchez

e-Research: A Journal of Undergraduate Work

Does the majority express interest concerning immigration on the basis of perceived personal economic circumstance and security, or on the basis of its perception of the state of the national economy? This study explains how perception of the state of the economy influences opinion on immigration policy. This study finds that an individual's preferences for varying immigration policies are rooted in his or her perception of the state of the national economy, rather than being narrowly determined by his or her perception of their own economic circumstance and security.

The Effects Of Room Color On Stress Perception: Red Versus Green Environments, Teresa M. Kutchma

Journal of Undergraduate Research at Minnesota State University, Mankato

The purpose of the study was to investigate the effects of red versus green room colors on individual perception of stress. Room color was found through previous studies to have specific effects on psychomotor activity and emotional states. Correlations were found between red room color and emotional and physical stimulation, while green was associated with inhibitory effects. Additionally, Goldstein’s theory of color perception showed that red has stimulating effects on human behavior. Subjects consisted of 15 female and 15 male college freshmen at Minnesota State University, Mankato. An experimental booth was used for red, green and white room conditions. Subjects …

An Examination Of The Relationship Between Attachment Style And Body Image In Adolescent Girls: A Focus On The Mother-Daughter Relationship, Jaclyn Bex

Dissertations - ALL

Using Bowlby's attachment theory and a family systems perspective, this study explored the relationships between attachment between mother and daughters, daughter's body image, and the daughter's perception of what her mother thinks of her body. It was hypothesized that secure attachment would correlate with satisfied body image in the daughters and the belief that their mother's had a satisfied image of the daughter's body. Participants were female undergraduate students recruited from a private university. Participants completed self-report questionnaires about attachment (Inventory of Parent and Peer Attachment, IPPA), body image (Contour Drawing Rating Scale, CDRS), and a researcher created demographic questionnaire. …

Short-Term Visual Deprivation, Tactile Acuity, And Haptic Solid Shape Discrimination, Charles E. Crabtree

Masters Theses & Specialist Projects

The visual cortex of human observers changes its functionality in response to visual deprivation (Boroojerdi et al., 2000). Behavioral studies have recently documented enhanced tactile abilities following a short period of visual deprivation (Facchini & Aglioti, 2003; Weisser, Stilla, Peltier, Hu, & Sathian, 2005). The current study investigated the effects of visual deprivation on two unique tactile tasks. While Facchini and Aglioti observed significant effects of visual deprivation, neither Wong, Hackeman, Hurd, and Goldreich (2011) nor Merabet et al. (2008) observed these effects. Corroborating these more recent results, no difference in grating orientation discrimination performance was observed between the sighted …

The Perception Of Distance On A Real Geographic Slope, David Alan Bunch

Dissertations

Ooi, Wu, and He (2001) have shown that for objects resting on flat, horizontal surfaces, those that appear in the lower sector of the visual field are perceived as close to the observer and objects located near the visual horizon are perceived as further from the observer. Researchers have hypothesized that observers utilize the angle subtended between the horizon and the line of sight to the target object as information for distance.In a previous investigation Hajnal, Bunch, and Kelty-Stephen (2014) showed that an object’s physical angle of declination below the horizon is not uniquely utilized when making distance estimates to …

Human Centered Design Applied To Perceptual Paradigms, Jonathan T. Fancher

All NMU Master's Theses

This thesis gives three examples of projects that apply knowledge from areas such as human centered design, computer science, and psychology to study sensation and perception. All three of these projects were created to gather information on how humans interact with their surrounding environment and the world. For instance the first area of discovery included the way humans interact within their perceptual and personal space through an interactive table. The second project looks at exploring the neural mechanisms that affect Haptic Hallucinations by creating a device that can give the feeling of bugs crawling on or below the surface of …

Affect Perception In Computer Mediated Communication, Rachel E. Townsend, Chris Allen

Student Research Symposium

The perception of affect influences the subjective perception of an individual’s environment (Isbell & Burns, n.d.). Accurate affect perception leads to increased resilience and positive coping mechanisms when faced with daily life stressors (Robinson, 2012). Communication technologies have revolutionized the ways in which individuals connect to one another professionally and socially (Walther, 1996). This study investigated accurate affect perception in computer mediated communication (CMC) from a multidisciplinary perspective.

Communication research posit several theories to accommodate the ways in which we communicate using CMC (J. B. Walther, 1996). Personality research has documented the correlation between the traits extraversion and neuroticism with …

Anger In The Courtroom: The Effects Of Attorney Gender And Emotion On Juror Perceptions, Christian B. May

Honors College Theses

This study sought to examine the effects of gender stereotypes of emotional expression on jurors’ perceptions of an attorney’s competence. Participants watched a video of a closing statement of a male or female attorney expressing either anger or neutral emotions and were asked to give a verdict and rate the attorney’s competence. Participants rated an angry male attorney highest in competence and an angry female attorney lowest in competence. Results also showed that participants who viewed a male attorney were more likely to attribute the attorney’s emotions to the situation compared to participants who viewed a female attorney. The implications …

Effects Of Perceptual Fluency On Reasoning And Pupil Dilation, Juan Diego Guevara Pinto

Honors College Theses

Research on perceptual disfluency has examined the effects of perceptually demanding stimuli on information processing and reasoning, suggesting that disfluent stimuli elicit slower and more effortful processing. Recent criticism of perceptual disfluency, however, suggests that the effects disfluent stimuli have on processing are marginal, and that they are mediated by individual differences. Participants completed a computerized reasoning task presented in either a fluent (i.e., easy-to-read font) or disfluent format (i.e., hard-to-read font) while pupil diameter was measured by an eye-tracker system. Pupillometry is an established reliable measure of mental activity that reflects differences in cognitive load. Results showed no performance …

Touch-Screen Technology For The Dynamic Display Of 2d Spatial Information Without Vision: Promise And Progress, Roberta L. Klatzky, Nicholas A. Giudice, Christopher R. Bennett, Jack M. Loomis

Spatial Information Science and Engineering Faculty Scholarship

Many developers wish to capitalize on touch-screen technology for developing aids for the blind, particularly by incorporating vibrotactile stimulation to convey patterns on their surfaces, which otherwise are featureless. Our belief is that they will need to take into account basic research on haptic perception in designing these graphics interfaces. We point out constraints and limitations in haptic processing that affect the use of these devices. We also suggest ways to use sound to augment basic information from touch, and we include evaluation data from users of a touch-screen device with vibrotactile and auditory feedback that we have been developing, …

Working Memory And Music Perception And Production In An Adult Sample, Keara L. Gillis

Undergraduate Honours Theses

This study examined the relationship between working memory and music perception and production in an adult population. Music perception and production was assessed using The Vocal Auditory Motor Development Assessment (VAMDA). Working memory was examined using both a forward and backward digit span test. A significant positive correlation was found between working memory and melody discrimination, while no significant relationship was found between working memory and pitch discrimination and production. Result implications and future research directions are discussed.

Hemispheric Processes In The Perception Of Art, A Literature Review, Megan Levy

Megan Levy

A literature review on Jeffrey Coney’s and Christine Bruce’s “Hemispheric Processes in the Perception of Art” (Journal of the International Association of Empirical Aesthetics, Empirical Studies of the Arts, Vol. 22(2) 181-200, 2004) presenting the results of their exploratory study on lateral asymmetry in the aesthetic evaluation of European art. This literature review proposes that Lateralization Theory, and specifically hemispheric preferences in art, are vast fields full of mystery and surprises, which require continuous research work within a deep understanding of the historical context. Coney’s and Bruce’s study is an example of interesting hard work which invites curiosity and replication, …

Examining The Relationship Between Familiarity And Reliability Of Automation In The Cockpit, Rian Mehta, Steven Rice, Scott Winter

Publications

This study sought to determine the correlation between familiarity and perceptions of reliability, as associated to specific aviation-related automated devices. Participants’ experience levels ranged from non-pilots to novice pilots to certified flight instructors. It was hypothesized that familiarity has a direct correlation with ratings of reliability for various aviation-related automated devices and that the correlation across devices for each participant would be positive. The researchers expected to find a difference in the familiarity-reliability relationship as a function of experience. Findings showed that there was a significant positive correlation between familiarity and reliability for every single automated device. A positive correlation …

What You See Is What You Forget : Alcohol Cue Exposure, Affect, And The Misinformation Effect, Camille Crocken Barnes

Legacy Theses & Dissertations (2009 - 2024)

Previous research has suggested that both alcohol cues and positive affect increase the tendency to incorporate false information into memory. This series of studies sought to determine if affect mediates the influence of alcohol cues on incorporation of false information into memory. Initially, a pilot study was completed to determine the individual differences that predict which individuals experience a heightening of positive affect following visualization exercises involving alcoholic beverages. Next, a study was conducted to determine if this affect increase from exposure to alcohol cues leads to increased acceptance of misinformation into memory. Participants' memories were tested while they were …

The Difference In Perception Of Gerotranscendence Between College Students And Healthy, Community-Dwelling Older Adults, Duc Viet Lai

All Graduate Theses, Dissertations, and Other Capstone Projects

Within the field of gerontology, some notable attempts to explain the aging process include activity theory, disengagement theory, Erikson's eight stages model, and socioemotional selectivity theory. The theory of gerotranscendence, recently developed by Lars Tornstam (1989), incorporates some aspects of these theories, and seeks to provide an overarching theme to the process of aging. The theory of gerotranscendence explains a shift in meta-perspective that a person experiences as they live, from a more materialistic and pragmatic view of the world to a more cosmic and transcendent one. Corresponding with this shift, the gerotranscendent individual exhibits certain behaviors, some of which …
