In past gender identity research, little attention has been paid to the determinants of the various dimensions of gender identity (felt pressure for gender differentiation, gender contentedness, and within-gender typicality). This study examined whether children’s self-perceptions and social behaviors influence changes in gender identity over time.

Show moreIn past gender identity research, little attention has been paid to the determinants of the various dimensions of gender identity (felt pressure for gender differentiation, gender contentedness, and within-gender typicality). This study examined whether children’s self-perceptions and social behaviors influence changes in gender identity over time. One hundred and ninety-five fourth- through seventh-graders completed self-report and peer-report questionnaires during the fall and spring of a school year. This study found that both felt pressure for gender differentiation and within-gender typicality are fluid, rather than stable, constructs during childhood. It also found that sex plays a significant role in not only which constructs influence gender identity, but which components of gender identity are influenced.

- Richter, Craig G., Charles E. Schmidt College of Science, Center for Complex Systems and Brain Sciences
- Abstract/Description
-
It is well established that anticipation of the arrival of an expected stimulus is accompanied by rich ongoing oscillatory neurodynamics, which span and link large areas of cortex. An intriguing possibility is that these dynamic interactions may convey knowledge that is embodied by large-scale neurocognitive networks from higher level regions of multi-model cortex to lower level primary sensory areas. In the current study, using autoregressive spectral analysis, we establish that during the...
Show moreIt is well established that anticipation of the arrival of an expected stimulus is accompanied by rich ongoing oscillatory neurodynamics, which span and link large areas of cortex. An intriguing possibility is that these dynamic interactions may convey knowledge that is embodied by large-scale neurocognitive networks from higher level regions of multi-model cortex to lower level primary sensory areas. In the current study, using autoregressive spectral analysis, we establish that during the anticipatory phase of a visual discrimination task there are rich patterns of coherent interaction between various levels of the ventral visual hierarchy across the frequency spectrum of 8 - 90 Hz. Using spectral Granger causality we determined that a subset of these interactions carry beta frequency (14 - 30 Hz) top-down influences from higher level visual regions V4 and TEO to primary visual cortex. We investigated the functional significance of these top-down interactions by correlating the magnitude of the anticipatory signals with the amplitude of the visual evoked potential that was elicited by stimulus processing. We found that in one third of the extrastriate-striate pairs, tested in three monkeys, the amplitude of the visual evoked response is well predicted by the magnitude of pre-stimulus coherent top-down anticipatory influences. To investigate the dynamics of the coherent and topdown Granger causal interactions, we analyzed the relationship between coherence and top-down Granger causality with stimulus onset asynchrony. This analysis revealed that in an abundance of cases the magnitudes of the coherent interactions and top-down directional influences scaled with the length of time that had elapsed before stimulus onset., Together these results reveal a complex network of coherent and top-down directional interactions that predict the amplitude of early components of the visual evoked potential in primary visual cortex and vary in strength on the basis of the length of the stimulus onset.

Working memory (WM) is an important cognitive function that, among other duties, allows temporary storage of visual representations of objects observed in the sensorium. The visual aspect of this core cognitive function enables our perception of the identity of objects and where those objects are located in space at any particular time to help direct attention.

Show moreWorking memory (WM) is an important cognitive function that, among other duties, allows temporary storage of visual representations of objects observed in the sensorium. The visual aspect of this core cognitive function enables our perception of the identity of objects and where those objects are located in space at any particular time to help direct attention. In a typical working memory task, a cue is presented beforehand to guide attention to which objects in an array to encode. The performance of our WM abilities can be improved on memory tasks by a retrospective cue resented after the encoding process of working memory. Several mechanisms have been proposed to explain etrospective cue benefits in WM performance, including the removal of irrelevant information from WM, attentional enhancement of the cued representation, protection of the cued representation from subsequent decay or interference, or retrieval head start.

Show moreMany studies have been devoted to investigating the process by which individuals make dispositional attributions about the people that they encounter. Typically, individuals are more likely to seek future interactions with target individuals if those target individuals have a positive or rewarding disposition. Interactions with target individuals possessing negative or punishing dispositions reduce the likelihood that target individual will be selected for future interactions. An initial false positive trait ascription will be self-correcting with future interactions. An initial false negative trait label will likely remain stable if future interactions are not forced. The importance of quick accurate disposition identification carries important evolutionary implications as well as normal-life implications. Results from an experiment support the ability of subjects to accurately identify the true trait of target individuals with limited dispositional information.

Show moreThis study examines the influence of various facets of perceived risk on the attitudes toward really new services (RNS) and adoption intentions. Although there is considerable research examining perceived risk and consumer adoption of innovations, three aspects of the relationship have been neglected. First, much of the research on really new innovations is product-focused with little attention to services. Second, there is limited research examining perceived risk as a multidimensional construct. Third, consumer characteristics that affect the relationship between perceived risks and adoption intentions have not been included in most of the innovation studies. Thus, this study seeks to provide answers to the questions of “which types of perceived risk are more likely to affect adoption intentions of RNS?” and “which consumer characteristics affect the relationship between perceived risks and adoption intentions of RNS?”. The findings of the study show the influence of perceived risk in the service innovations area. We contribute to theory and practice by identifying the specific risks that cause consumers to resist adopting RNS as well as showing the explanatory power of Regulatory Focus Theory (RFT) to understand why consumers react differently when they encounter service innovations.

Show moreIn the present study, it was examined whether the spatiotemporal dynamics of transitions towards target dominance in motion-induced blindness (MIB) were wave-like, similar to those in binocular rivalry. The spatiotemporal dynamics of transitions towards dominance in MIB were further compared with those in binocular rivalry to reveal a potential neural locus of MIB. Across a series of experiments, the relationship between target length, stimulus structure, presentation location and the latency for circular arc segment-shaped targets to reappear was examined, respectively. It was found that target reappearance durations increase with target length, as if they reappear in a gradual, wavelike fashion. Target reappearance durations were decreased for collinear compared to radial targets, but they were not influenced by the location of target presentation. The results suggest MIB target reappearances are associated with traveling waves of dominance, and early visual cortex is a likely neural substrate in which these wave-like transitions occur.

Show moreAlthough it is well known that the pupil responds dynamically to changes in ambient light levels, the results from this dissertation show for the first time that the pupil also responds dynamically to changes in spatially distributed attention. Using a variety of orientating tasks, subjects alternated between focusing attention on a central stimulus and spreading attention over a larger area. Fourier analysis of the fluctuating pupil diameter indicated that: 1) pupil diameter changed at the rate of attention variation, dilating with broadly spread attention and contracting with narrowly focused attention, and 2) pupillary differences required changes in attentional spread; there were no differences in pupil diameter between sustained broad and sustained spread attention. Given that broadly spread attention increases the relative activation of large receptive fields and narrowly focused attention increases the relative activation of small receptive fields (Balz & Hock, 1997), the results of this study indicate that these attentional effects on receptive field activation can be mediated by changes in pupil diameter. That is, under broad attention, the corresponding pupillary dilation observed would increase spherical aberration, blurring the image thereby reducing high spatial frequency information and decreasing the activation of relatively small cortical receptive fields compared to relatively large receptive fields. This increased perception of low spatial frequencies would be beneficial in cases where attention is spread over a large area. Alternatively, under narrow attention the resulting pupillary constriction reduces spherical aberration sharpening the image and preserving high spatial frequency information resulting in a relatively increased response of small receptive fields.

- THE "OBLIQUE EFFECT" IN THE SPATIAL REPRESENTATION OF CHILDREN FOR THE HORIZONTAL AND VERTICAL PLANE.
- Creator
- HILTON, THOMAS FREDERICK, Florida Atlantic University
- Abstract/Description
-
The effect of stimulus plane orientation (horizontal vs vertical) on mirror-image oblique discrimination was investigated for children 5 to 8 years of age. A significant difference in learning rate favoring the vertical plane presentation was obtained. Tracing the stimuli had no effect on learning rate in either the horizontal or vertical plane. The results were explained in terms of egocentricity in the child's representation of spatial relations.

This study tested the hypothesis that children's mental representations of their family experiences cause them to have reactions during peer interactions that lead to their victimization by peers. It was suggested that a perception of the self as helpless and a perception of the parent as controlling or threatening causes children to exhibit debilitated behavior among peers that contributes to their victimization. Also, certain perceptions of self and parent may contribute to aggression toward peers. Results for boys were in accord with hypotheses, in that both victimization and aggression were predicted by interactions of perceptions-of-self with perceptions-of-parent. Results for girls were less predictable from the formulation.

H may be useful alternative to variance from the mean in identifying individuals for whom a trait is meaningful despite the high variability of endorsements. Low H indicated order. H correlated negatively with SC, SE, SS, ratings of traits, roles, and importance as predicted. SC accounted for some of the variance of the relations; SS, however, was found to play a greater role in the relations of entropy and global properties.

Show moreCan a distributed anatomical and functional architecture serve as the basis for sufficiently complex perceptual phenomena? In addressing this question, the conceptual notion of dynamical system and its relation to other paradigms is considered including its definition. The principal goal is to develop a dynamical framework on which to ground the theoretical study of perception and other physical phenomena. As an entry point, the perceptual dynamics of auditory streaming are modeled using a neurally inspired dynamical model of auditory processing. Traditional approaches view streaming as a competition of streams, realized within a tonotopically organized neural network. In contrast, streaming can be viewed as a dynamic integration process involving locations (information convergence zones) other than the sensory specific neural subsystems. This process finds its realization in the synchronization of neural ensembles. Consequently, the model employs two interacting dynamical systems. The first system responds to incoming acoustic stimuli and transforms them into a spatiotemporal neural field dynamics. The second system is a classification system coupled to the neural field and evolves to a stationary state in the absence of input. The states of the classification system at any time t are identified with a single perceptual stream or multiple streams. Several results in human perception are modeled including temporal coherence and fission boundaries (van Noorden, 1975), and crossing of motions (Bregman, 1990). The model predicts phenomena such as the existence of two streams with the same pitch. So far, this has not been explained by the traditional stream competition models. A psychophysical study provides proof of existence of this phenomenon. Using set theoretical expressions on fMRI data, evidence was found showing that the percept of auditory streaming involves regions (convergence zones) other than just the primary auditory areas. This is a necessary condition for the existence of the network architecture proposed in the auditory streaming model. Networks specific and common to both amplitude and frequency streaming were identified. This lends support to models of perception conceived as interacting neural subnetworks acting as functional differentiation areas and information convergence zones for the classification of the perceptual world as suggested by the introductory question.

This specific memory error involves improperly pairing two or more feature memories together in the long-term store. In our study, these features were the action and the actress performing the action. Our study involved 51 participants. Participants were shown target events in Week 1 and asked to retrieve the target events from a larger group of events in Week 2. While findings did not show the expected interaction of conjunction events to object presence or absence, objects without an object showed a significantly higher acceptance rate. A secondary analysis revealed an interaction effect between head-focus and recognition item type, meaning participants did view events without an object differently from objects with an object.

Show moreWhen motion occurs in a scene, the quality of video degrades due to motion smear, which results in a loss of contrast in the image. The characteristics of the human vision system when smooth pursuit eye movements occur are different from those when the eye fixates on an object such as a video screen during motion. Smooth pursuit eye movements dominate in the presence of dynamic stimuli. In the presence of smooth pursuit eye movements, the contrast sensitivity for increasing target velocities shifts toward lower spatial frequencies. The sensitivity for low spatial frequencies during motion is higher than for a stationary case. This dissertation will propose a method to improve the perceptual quality of video using temporal enhancement prefiltering technique based on the characteristics of Smooth Pursuit Eye Movements (SPEM). The resulting technique closely matches the characteristics of the human visual system (HVS). When motion occurs, the eye tracks the moving targets in a scene as opposed to fixating on any portion of the scene. Hence, psychophysical studies of smooth pursuit eye movements were used as a basis to design the temporal filters. Results of experiments show that temporal enhancement results in improved quality by increasing the apparent sharpness of the image sequence. In this dissertation, a study of research describing how motion affects the image quality at the camera lens and the human eye is presented. This dissertation uses that research to develop a temporal enhancement technique to improve the quality of video degraded by motion.

Show moreThe way we think about ourselves is reflected in, and shaped by, the way we think about our actions. The identification of action can vary from mechanistic, low level depictions to far more comprehensive, high level depictions. This study tests the supposition that comprehensive understanding of action is a precondition for coherence in self-concept and that failure to generate stable, high level action identifications interferes with the formation of a stable and personally certain self-concept. It was predicted (and the results confirmed) that persons who experience fragmented action understanding (i.e., relatively low level action identification) demonstrate less coherence in their overall self-evaluative stance and greater self-uncertainty and self-instability. The relationships between self-concept and coherence (i.e., self-stability and self-certainty) and action identification level was studied in both a context-free manner and with respect to specific social roles. The results expand our understanding of the nature and impact of the organizational processes at work within the self system.

The main hypothesis that expected self-reactions would show the strongest relationship to school outcomes was supported for both sexes. Some evidence of best friend influences was found for girls, with best friend reactions to positive affect in girl targets a positive predictor of achievement, and best friend reactions to positive affect in boy targets a negative predictor. Both boys' and girls' anticipated positive self-reactions to high academic performance in male (but not female) targets were strong predictors of children's own achievement scores and grades.

Although other work has demonstrated a processing advantage for multimodal stimuli, research on infants' responsiveness to nonnative contrasts so far has not examined whether concurrent auditory and visual speech information can modulate perceptual narrowing. Thus, the current study investigated the influence ofbimodally specified speech sounds on infants' sensitivity to a nonnative phonemic contrast. Six-month-old and 10- to 12-month-old infants were tested in a habituation/test procedure for discrimination of an audiovisual nonnative speech contrast (Hindi /tal dental vs. /Tal retroflex stop). Findings showed that infants at both ages exhibited evidence of discrimination following habituation to one of the speech sounds. These findings suggest that the usually observed decline in responsiveness to nonnative speech contrasts is limited to audibly specified contrasts and that concurrent visual speech information enhances the discriminability of such contrasts.

Third-order synthetic neural networks are applied to the recognition of isodensity facial images extracted from digitized grayscale facial images. A key property of neural networks is their ability to recognize invariances and extract essential parameters from complex high-dimensional data. In pattern recognition an input image must be recognized regardless of its position, size, and angular orientation.

Show moreThird-order synthetic neural networks are applied to the recognition of isodensity facial images extracted from digitized grayscale facial images. A key property of neural networks is their ability to recognize invariances and extract essential parameters from complex high-dimensional data. In pattern recognition an input image must be recognized regardless of its position, size, and angular orientation. In order to achieve this, the neural network needs to learn the relationships between the input pixels. Pattern recognition requires the nonlinear subdivision of the pattern space into subsets representing the objects to be identified. Single-layer neural networks can only perform linear discrimination. However, multilayer first-order networks and high-order neural networks can both achieve this. The most significant advantage of a higher-order net over a traditional multilayer perceptron is that invariances to 2-dimensional geometric transformations can be incorporated into the network and need not be learned through prolonged training with an extensive family of exemplars. It is shown that a third-order network can be used to achieve translation-, scale-, and rotation-invariant recognition with a significant reduction in training time over other neural net paradigms such as the multilayer perceptron. A model based on an enhanced version of the Widrow-Hoff training algorithm and a new momentum paradigm are introduced and applied to the complex problem of human face recognition under varying facial expressions. Arguments for the use of isodensity information in the recognition algorithm are put forth and it is shown how the technique of coarse-coding is applied to reduce the memory required for computer simulations. The combination of isodensity information and neural networks for image recognition is described and its merits over other image recognition methods are explained. It is shown that isodensity information coupled with the use of an "adaptive threshold strategy" (ATS) yields a system that is relatively impervious to image contrast noise. The new momentum paradigm produces much faster convergence rates than ordinary momentum and renders the network behaviour independent of its training parameters over a broad range of parameter values.
