Title: Infant Jealousy Responses: Temperament and EEG.
Creator: Mize, Krystal D., Florida Atlantic University, Jones, Nancy Aaron, Bjorklund, David F., Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: Jealousy results from the fear of loss of an important relationship partner or his/her exclusive attention (Neu, 1980; Tov-Ruach, 1980). Infants are dependant on their caregivers for basic needs and emotional support. Therefore, if an infant perceives that a rival threatens the parent-child dyad relationship, it is possible that the infant will respond in a jealous manner just as adults do when their important relationships are threatened .

Show moreJealousy results from the fear of loss of an important relationship partner or his/her exclusive attention (Neu, 1980; Tov-Ruach, 1980). Infants are dependant on their caregivers for basic needs and emotional support. Therefore, if an infant perceives that a rival threatens the parent-child dyad relationship, it is possible that the infant will respond in a jealous manner just as adults do when their important relationships are threatened . Although infants have limited emotional understanding, Palmer and Palmer (2002) suggest that jealousy evolved out of other resource-protecting drives. Because parental care is a valuable resource, supporting survival, infants may have at least precursory jealousy capabilities. Research on infant jealousy is minimal however, Hart and Carrington (2002) characterized approach responses to the loss of maternal attention to a life-like doll as jealousy. The purpose ofthe current repeated-measures research design is to provide a conceptual replication of previous infant jealousy research. Whether infant jealousy responses are moderated by individuals approach or withdrawal tendencies, is still to be determined and is another focus of the current research. Temperamental characteristics may influence emotional responses and asymmetrical frontal brain activity is associated with individual differences in emotional responding (see Coan & Allen, 2004 for a review). Therefore baseline electroencephalography (EEG) is collected in the current research followed by subjecting 15 infants (mean age = 12.87 months) to two maternal ignoring conditions, one involving the mother attending to a social object (lifelike doll) and a control condition in which the mother attends to a non-social object (book). Results show that infants respond differentially to the two conditions with increased approach behaviors, arousal, and negative affect in the doll condition. The infants' responses in the social-object condition are identified as jealousy, suggesting that infants are capable of at least some complex emotional experiences. v

Title: A visual perception threshold matching algorithm for real-time video compression.
Creator: Noll, John M., Florida Atlantic University, Pandya, Abhijit S., College of Engineering and Computer Science, Department of Computer and Electrical Engineering and Computer Science
Abstract/Description: A barrier to the use of digital imaging is the vast storage requirements involved. One solution is compression. Since imagery is ultimately subject to human visual perception, it is worthwhile to design and implement an algorithm which performs compression as a function of perception. The underlying premise of the thesis is that if the algorithm closely matches visual perception thresholds, then its coded images contain only the components necessary to recreate the perception of the visual...
Show moreA barrier to the use of digital imaging is the vast storage requirements involved. One solution is compression. Since imagery is ultimately subject to human visual perception, it is worthwhile to design and implement an algorithm which performs compression as a function of perception. The underlying premise of the thesis is that if the algorithm closely matches visual perception thresholds, then its coded images contain only the components necessary to recreate the perception of the visual stimulus. Psychophysical test results are used to map the thresholds of visual perception, and develop an algorithm that codes only the image content exceeding those thresholds. The image coding algorithm is simulated in software to demonstrate compression of a single frame image. The simulation results are provided. The algorithm is also adapted to real-time video compression for implementation in hardware.

Title: The relations of peer perceptions to children's academic achievement.
Creator: Ashley, Elizabeth A., Florida Atlantic University, Perry, Louise C.
Abstract/Description: Two studies were conducted in which children's (Grades 3--8) perceptions of classmates' academic performance, school affect, and behavioral conduct were examined in relation to achievement outcomes as measured by standardized achievement test scores in language, mathematics, and science, and school grades in English, mathematics, and science.

Show moreTwo studies were conducted in which children's (Grades 3--8) perceptions of classmates' academic performance, school affect, and behavioral conduct were examined in relation to achievement outcomes as measured by standardized achievement test scores in language, mathematics, and science, and school grades in English, mathematics, and science. Study 1 was a longitudinal design and the main research question addressed was whether the way a child's peers perceive him or her with respect to school characteristics would be related to children's academic outcomes concurrently, and one year later. Support was found for several hypotheses advanced. Peers' perceptions were related to children's concurrent achievement test scores and school grades. Peers' perceptions were also generally predictive of the following year's school grades. Domain differences were found in that peers' perceptions of academic performance were more strongly predictive than affect or conduct domain judgments. Peers' perceptions were also more strongly related to school grades than to achievement test scores. The second study continued the examination of peers' perceptions with additional perceptions measured from children's self-judgments and teachers' ratings. In Study 2, the main question explored was whether peers' perceptions of children's academic qualities would be predictive of children's concurrent achievement outcomes beyond children's self-perceptions and teachers' perceptions. Results showed that even after controlling for both self and teacher judgments, peers' perceptions were strongly related to all school grades. Theoretical and practical implications of the research findings were discussed and suggestions for future research were offered.

Title: Global feedback in hierarchical motion pattern formation.

Show moreAn array of four motion quartets (stimuli for which either horizontal or vertical motion is perceived depending on quartet aspect ratio) is arranged in a diamond configuration such that two global motion patterns are formed: (1) Rotation---alternating counterclockwise and clockwise motion is perceived, and (2) Parallel path motion---the perceived motions of all the elements are simultaneously horizontal or simultaneously vertical. The perception of rotation resulted in global feedback that biases the motion perceived for an individual component motion quartet to be more consistent with rotation than aspect ratio. Stronger rotation produced greater bias. Under certain conditions, the feedback-induced bias occurred even though global rotation was not perceived. The results were interpreted in the context of neurophysiological evidence regarding neurons in Areas MT and MSTd, and a dynamical theory of motion pattern formation (Hock, Schoner & Giese, 2003; Nichols, Hock & Schoner, 2006).

Title: Selective exposure attribution theory: Implications for better than average biases.

Most research suggests that the effect results from motivations to inflate levels of self-esteem (Alicke, 1985). The present study challenged that an information-processing mechanism driven by selective exposure of persons to the behaviors of others may instead promote an overall negative dispositional asymmetry within a population. When subjects were asked to make assessments regarding a target's level of trait across situations permitting various levels of selective exposure, the data indicated an increased tendency to rate others more negatively when selective exposure was maximized. It was hypothesized that subjects had committed more "false negative attribution errors" and had corrected more "false positive attribution errors" upon drawing their conclusions.

Show moreCultural geographic theory uses dramatic language (place ballets , time-space routines, temporal rhythms , etc.) to describe how humans sense and dwell in places. Because the theory contemplates human behavior enacted upon a stage, it is applicable to theater studies. This thesis asserts that Hamlet's, Othello's, and Antony's treacherous lifeworlds undermine their spatiotemporal senses and initiate quests similar to those described by Anne Buttimer as searches "for order, predictability, and routine, as well as [...] for adventure and change" ("Grasping" 285). Hamlet's revenge plot is a pursuit of order and reclamation of his identity at Elsinore. Desdemona's murder is Othello's attempt to salvage his character, which he believed sullied by infidelity. Alexandria offers Antony a life opposite Rome's and sets him on a course of indecisiveness. These plays demonstrate that, at the point of cultural contact, routines are interrupted and identities destabilize. Tragically, the characters lose themselves in the turmoil.

By applying the so-called 'Smith-Waterman (SW) local alignment' and 'Needleman-Wunsch (NW) global alignment' approaches of bioinformatics, a test 2D-image in binary format is compared against a reference image so as to recognize the differential features that reside locally in the images being compared 2. SW and NW algorithms based binary comparison involves conversion of one-dimensional sequence alignment procedure (indicated traditionally for molecular sequence comparison adopted in bioinformatics) to 2D-image matrix 3. Relevant algorithms specific to computations are implemented as MatLabTM codes 4. Test-images considered are: Real-world bio-/medical-images, synthetic images, microarrays, biometric finger prints (thumb-impressions) and handwritten signatures. Based on the results, conclusions are enumerated and inferences are made with directions for future studies.

Previous studies of gaze behavior demonstrate a tendency to stare into a target’s eyes, however no studies investigate the differences between when participants believe they are engaging in a live interaction compared to knowingly watching a pre-recorded video, a distinction that may contribute to studies of memory encoding. This study examined differences in fixation behavior for when participants falsely believed they were engaging in a real-time interaction over the internet (“Real-time stimulus”) compared to when they knew they were watching a pre-recorded video (“Pre-recorded stimulus”). Results indicated that participants fixated significantly longer towards the eyes for the pre-recorded stimulus than for the real-time stimulus, suggesting that previous studies which utilize pre-recorded videos may lack ecological validity.

Abstract/Description: Research on Multiple Object Tracking (MOT) has typically involved 2D displays where stimuli move in a single depth plane. However, under natural conditions, objects move in 3D which adds complexity to tracking. According to the spatial interference model, tracked objects have an inhibitory surround that when crossed causes tracking errors. How do these inhibitory fields translate to 3D space?

However, under natural conditions, objects move in 3D which adds complexity to tracking. According to the spatial interference model, tracked objects have an inhibitory surround that when crossed causes tracking errors. How do these inhibitory fields translate to 3D space? Does multiple object tracking operate on a 2D planar projection, or is it in fact 3D? To investigate this, we used a fully immersive virtual-reality environment where participants were required to track 1 to 4 moving objects. We compared performance to a condition where participants viewed the same stimuli on a computer screen with monocular depth cues. Results suggest that participants were more accurate in the VR condition than the computer screen condition. This demonstrates interference is negligent when the objects are spatially distant, yet proximate within the 2D projection.

I used a three-part methodology to determine if color discrimination occurred. FIrst, I exposed naèive, light-adapted hatchlings to either a blue, green or yellow light. I manipulated light intensity to obtain a behavioral phototaxis threshold to each color, which provided a range of intensities we knew turtles could detect. Second, I used food to train older turtles to swim toward one light color, and then to discriminate between the rewarded light and another light color ; lights were presented at intensities equally above the phototaxis threshold. Lastly, I varied light intensity so that brightness could not be used as a discrimination cue. Six turtles completed this task and showed a clear ability to select a rewarded over a non-rewarded color, regardless of stimulus intensity. Turtles most rapidly learned to associate shorter wavelengths (blue) with food. My results clearly show loggerheads have color vision. Further investigation is required to determine how marine turtles exploit this capability.

Show moreJealousy is a response to a situation in which a person feels a combination of different emotions, such as love, anger, sadness and fear when an affectionate interaction is happening between a loved one and someone else. This paper discusses the definition and onset of infant jealousy, the physiological basis of jealousy, whether maternal factors play a role, as well as studies on jealousy and EEG patterns. It has been argued that infants, as young as six-months-old display jealous-like behaviors. During jealousy evocation conditions, infants demonstrate negative emotions such as protesting or crying, diminished distancing, and heightened gaze toward their mother during maternal inattention. Approach/withdrawal behaviors and electroencephalography (EEG) activation were studied in the context of an infant jealousy paradigm. In this investigation, 45 mother-infants dyads were exposed to a social versus non-social condition during maternal inattention. During the social condition, infants demonstrated increased approach-style gaze and reach and negative affect. EEG was collected during all conditions on a subsample of 15 infants and in agreement with adult jealousy literature (Harmon-Jones, Peterson, & Harris, 2009), infants displayed left midfrontal EEG asymmetry, and displayed more approach motivations during the social doll condition indicative of jealousy approach motivations.

Show moreJohn Crowley’s Little, Big is an innovative piece of fantasy writing. This thesis aims to prove that Crowley’s innovation lays the groundwork for new avenues in which fantastic space can be manipulated and constructed. Deep study in Euclidean geometry, modern physics, and occult astronomy reveal a new fantastic space, and a new concept for the threshold of Faerie. Crowley’s fantastic space is constructed as infundibular; with layers of concentricities that funnels his characters to their final destination of self-actualization and the heaven-like realm of Faerie. Crowley amalgamates the boundaries of Faerie and the primary world in an unusual fashion that is noted as Coalesced Fantasy: a fantasy wherein there is ultimately no dichotomy between Faerie and the primary world, as there is no division between the fantastic and science. This deliberate aim to blend boundaries is to establish an All in One theory. Faerie and the primary world oppose each other as antithetical conical space, and Crowley’s Edgewood house serves as the threshold to allow man to access the divinity and vastness of Faerie. Faerie (Divinity/macrocosm) and man (microcosm) exist in and amongst one another; everything is connected and every path intersects, spinning on a hyperbolic plane in this new, quantifiable space.

Show moreBackground: Light-adaptation is a multifaceted process in the retina that helps adjust the visual system to changing illumination levels. Many studies are focused on the photochemical mechanism of light-adaptation. Neural network adaptation mechanisms at the photoreceptor synapse are largely unknown. We find that large, spontaneous Excitatory Amino Acid Transporter (EAATs) activity in cone terminals may contribute to cone synaptic adaptation, specifically with respect to how these signals change in differing conditions of light. EAATs in neurons quickly transport glutamate from the synaptic cleft, and also elicit large thermodynamically uncoupled Cl- currents when activated. We recorded synaptic EAAT currents from cones to study glutamate-uptake events elicited by glutamate release from the local cone, and from adjacent photoreceptors. We find that cones are synaptically connected via EAATs in dark ; this synaptic connection is diminished in light-adapted cones. Methods: Whole-cell patch-clamp was performed on dark- and transiently light-adapted tiger salamander cones. Endogenous EAAT currents were recorded in cones with a short depolarization to -10mV/2ms, while spontaneous transporter currents from network cones were observed while a local cone holding at -70mV constantly. DHKA, a specific transporter inhibitor, was used to identify EAAT2 currents in the cone terminals, while TBOA identified other EAAT subtypes. GABAergic and glycinergic network inputs were always blocked with picrotoxin and strychnine. Results: Spontaneous EAAT currents were observed in cones held constantly at -70mV in dark, indicating that the cones received glutamate inputs from adjacent photoreceptors. These spontaneous EAAT currents disappeared in presence of a strong light, possibly because the light suppressed glutamate releases from the adjacent photoreceptors. The spontaneous EAAT currents were blocked with TBOA, but not DHKA, an inhibitor for EAAT2 subtype, suggesting that a, non-EAAT 2 subtype may reside in a basal or perisynaptic area of cones, with a specialized ability to bind exocytosed glutamate from adjacent cones in dark. Furthermore, these results could be artificially replicated by dual-electrode recordings from two adjacent cones. When glutamate release was elicited from one cone, the TBOA-sensitive EAAT currents were observed from the other cone. Conclusions: Cones appear to act like a meshwork, synaptically connected via glutamate transporters. Light attenuates glutamate release and diminishes the cone-cone synaptic connections. This process may act as an important network mechanism for cone light adaptation.

Show moreOur everyday world consists of people and objects that are usually specified by dynamic and concurrent auditory and visual attributes, which is known to increase perceptual salience and, therefore, facilitate learning and discrimination in infancy. Interestingly, early experience with faces and vocalizations has two seemingly opposite effects during the first year of life, 1) it enables infants to gradually acquire perceptual expertise for the faces and vocalizations of their own race and, 2) it narrows their ability to discriminate the faces of other-race faces (Kelly et al., 2007). It is not known whether multisensory redundancy might help older infants overcome the other-race effect reported in previous studies. The current project investigated infant discrimination of dynamic and vocalizing other-race faces in younger and older infants using habituation and eye-tracking methodologies. Experiment 1 examined 4-6 and 10-12-month-old infants' ability to discriminate either a native or non-native face articulating the syllable /a/. Results showed that both the 4-6- and the 10-12-month-olds successfully discriminated the faces,regardless of whether they were same- or other-race faces. Experiment 2 investigated the contribution of auditory speech cues by repeating Experiment 1 but in silence. Results showed that only the 10-12-month-olds tested with native-race faces successfully discriminated them. Experiment 3 investigated whether it was speech per se or sound in general that facilitated discrimination of the other-race faces in Experiment 1 by presenting a synchronous, computer-generated "boing" sound instead of audible speech cues. Results indicated that the 4-6-month olds discriminated both types of faces but that 10-12-month-olds only discriminated own-race faces. These results indicate that auditory cues, along with dynamic visual cues, can help infants overcome the effects of previously reported narrowing and facilitate discrimination of other-race static, silent faces. Critically, our results show that older infants can overcome the other race-effect when dynamic faces are accompanied by speech but not when they are accompanied by non- speech cues. Overall, a generalized auditory facilitation effect was found as a result of multisensory speech. Moreover, our findings suggest that infants' ability to process other- race faces following perceptual narrowing is more plastic than previously thought.

Show moreA variety of classifiers for solving classification problems is available from the domain of machine learning. Commonly used classifiers include support vector machines, decision trees and neural networks. These classifiers can be configured by modifying internal parameters. The large number of available classifiers and the different configuration possibilities result in a large number of combinatiorrs of classifier and configuration settings, leaving the practitioner with the problem of evaluating the performance of different classifiers. This problem can be solved by using performance metrics. However, the large number of available metrics causes difficulty in deciding which metrics to use and when comparing classifiers on the basis of multiple metrics. This paper uses the statistical method of factor analysis in order to investigate the relationships between several performance metrics and introduces the concept of relative performance which has the potential to case the process of comparing several classifiers. The relative performance metric is also used to evaluate different support vector machine classifiers and to determine if the default settings in the Weka data mining tool are reasonable.

Show moreMother-child interactions that might predict peer victimization for children during middle childhood were examined. 184 middle class boys and girls in the 4th through 7th grades participated in the study. Child report measures of 6 dimensions of maternal parenting style and 7 types of child coping during mother-child conflict were developed. These family variables were reduced to a smaller set of variables and related to peer reports of children's victimization by peers, internalizing problems with peers, and externalizing problems with peers. Results indicate that, for boys, maternal overprotectiveness is associated with peer victimization for boys who use fearful or submissive coping during mother-child conflicts. Maternal overprotectiveness also predicts boys' internalizing problems with peers. Moreover, boys' internalizing problems with peers mediate the relation between maternal overprotectiveness and peer victimization. For girls, maternal hostility is associated with peer victimization for girls who are physically weak, and maternal hostility predicts internalizing problems with peers. As is the case with boys, internalizing problems with peers mediate the link between maternal hostility and victimization by peers. For both boys and girls, maternal hostility predicted externalizing problems with peers. A theory that explains gender differences in relations between maternal behaviors and peer victimization was advanced.

Title: Poor self-concept and victimization by peers: Untangling the direction of influence.
Creator: Egan, Susan K., Florida Atlantic University, Perry, David G.
Abstract/Description: The present study examines whether one aspect of problematic adjustment--poor self-concept--contributes to victimization, is a consequence of victimization, or both. A sample of 187 third- through seventh-grade children were tested in both the fall and spring of the academic year on four self-report, self-concept measures: (a) global self-esteem, (b) social self-esteem, (c) self-efficacy for assertion, and (d) self-efficacy for aggression. At both times of testing, children also reported...

A sample of 187 third- through seventh-grade children were tested in both the fall and spring of the academic year on four self-report, self-concept measures: (a) global self-esteem, (b) social self-esteem, (c) self-efficacy for assertion, and (d) self-efficacy for aggression. At both times of testing, children also reported classmates who manifested both victimized and aggressive behaviors. Results indicated that social self-esteem and self-efficacy were both antecedents of victimization even after controlling for T1 levels of victimization. Social self-esteem was also an outcome of victimization after controlling for T1 levels of social self-esteem. A secondary consideration of the research was to investigate whether poor self-concept is predictive or an outcome of aggression, and results are discussed. Theoretical explanations for the specific relations found are advanced.

Title: Allusions.
Creator: Nuruddin, Khaulah Naima, Prusa, Carol, Florida Atlantic University, Dorothy F. Schmidt College of Arts and Letters, Department of Visual Arts and Art History
Abstract/Description: Allusions explores the volatile nature of intimate relationships by revisiting and recovering my memory of dramatic experiences in my own intimate relationships then translating them into painted psychological scenes. These scenes are activated by symbolically charged objects and interrupted by openings or portals serving as points of entry or exit. The people involved are referred to by pieces of carefully chosen furniture situated in a space that has shifting perspectives and illogical...
Show moreAllusions explores the volatile nature of intimate relationships by revisiting and recovering my memory of dramatic experiences in my own intimate relationships then translating them into painted psychological scenes. These scenes are activated by symbolically charged objects and interrupted by openings or portals serving as points of entry or exit. The people involved are referred to by pieces of carefully chosen furniture situated in a space that has shifting perspectives and illogical planes, referencing the complexity of memory and the subjectivity of experience. Discordant color, texture, and layered information are used to heighten the drama of the moment. These painted panels and ceramic structures are a manifestation of my mental processing of interpersonal exchanges and remembered experiences through the development of a unique visual vocabulary in paint.

Title: Components of self.
Creator: Major, Christina Maya., Dorothy F. Schmidt College of Arts and Letters, Department of Visual Arts and Art History
Abstract/Description: My thesis exhibition is comprised of approximately eleven large-scale portrait paintings done primarily in oil paint on canvas. This body of work investigates the ways the identity of both artist and subject can coexist in a portrait and evolved from my desire to combine portrait painting with writing as well as to develop methods of using paint to express a merging of myself with the individual depicted in the portrait. My creative research has focused on the traditional form of the portrait...
Show moreMy thesis exhibition is comprised of approximately eleven large-scale portrait paintings done primarily in oil paint on canvas. This body of work investigates the ways the identity of both artist and subject can coexist in a portrait and evolved from my desire to combine portrait painting with writing as well as to develop methods of using paint to express a merging of myself with the individual depicted in the portrait. My creative research has focused on the traditional form of the portrait as a powerful form of representing an individual and how meaning can be expanded through scale, brushstroke, color, texture, composition and the many variables that portraiture deals with. I expanded on the traditional portrait painting by cataloguing my memories and thoughts along with the thoughts of the subject by painting under, into and over the subject in my own handwriting. My "hand" is visible both in the brushstroke and in the cursive writing, preserving my identity in a "readable" way both literally and through graphology, or handwriting analysis.
