Title: AUTOMATIC SEQUENTIAL PRIMING OF DIGITS.
Creator: SYLVAN, ANITA., Florida Atlantic University
Abstract/Description: Previous research has shown that priming of digits is a function of the ordinal distance of the target digit from the priming sequence and that under certain conditions this effect may be automatic. The present experiment, which employs a choice RT task, was designed to test automaticity by manipulating subjects' expectancies and the time available for processing the priming sequence. Schematically valid primes (e.g., "1,2,3" preceding "4") were presented on 30%, 50%, or 70% of the trials to...
Show morePrevious research has shown that priming of digits is a function of the ordinal distance of the target digit from the priming sequence and that under certain conditions this effect may be automatic. The present experiment, which employs a choice RT task, was designed to test automaticity by manipulating subjects' expectancies and the time available for processing the priming sequence. Schematically valid primes (e.g., "1,2,3" preceding "4") were presented on 30%, 50%, or 70% of the trials to a given subject. Invalid primes (e.g., "5, 6, 7" preceding "4") were presented on the remaining trials. There was a highly significant effect of priming modified by interactions with exposure time and frequency. Employing a cost-benefit analysis to the frequency factor, it was found that the most frequently occurring prime resulted in decreased response latency but the less frequently occurring prime did not result in an increase in response latency (benefit wihout cost). On this basis, it is concluded that frequency influences an automatic process in this experiment. Since frequency interacts with priming, it is therefore argued that priming also affects an automatic process.

Title: PERCEPTUAL SEGREGATION AND THE CATEGORY EFFECT.
Creator: ROSENTHAL, ALAN., Florida Atlantic University, Hock, Howard S., Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: A category effect of alphanumeric characters in a visual search paradigm was examined to see whether the effect could be accounted for by the number of memory comparisons or by an early stage of perceptual processing. In Experiments 1 and 2, subjects searched for targets in either a within-category or between-category condition. The two experiments differed by the point in the trials where "catch trials" were presented. Experiment 3 used new configurations based on Gestalt principles which...
Show moreA category effect of alphanumeric characters in a visual search paradigm was examined to see whether the effect could be accounted for by the number of memory comparisons or by an early stage of perceptual processing. In Experiments 1 and 2, subjects searched for targets in either a within-category or between-category condition. The two experiments differed by the point in the trials where "catch trials" were presented. Experiment 3 used new configurations based on Gestalt principles which had been shown to influence target detection times at an early level of perceptual processing. The results of Experiments 1 and 2 favored a perceptual explanation mediating the effect. In Experiment 3, the critical interaction of category and Gestalt factors which would have demonstrated a competition in perceptually parsing the display fell short of significance.

Subjects received descriptions of a hypothetical individual and then gave trait judgments indicating how they perceived this person. Subjects continued to receive information and make judgments through ten successive trials. Correlations were performed between seven major variables evaluated over the course of the trials. Results showed that the major work of impression formation occurs early in the process and that less is accomplished as time goes on. It was also found that an information processing point of view accommodated much of the results quite nicely.

Title: HEMISPHERIC DIFFERENCES IN THE EFFECT OF STIMULUS FAMILIARITY ON PERCEIVED DURATION.
Creator: MURPHY, ARTHUR LORD, Florida Atlantic University
Abstract/Description: A paired-comparisons procedure was used to obtain relative duration judgements of identical pairs of normal (e.g. A vs. A) or rotated (e.g.V vs.V) letters. Each pair of letters was presented simultaneously for a duration of 50msec, with one letter in the LVF (left visual field, right hemisphere), and one in the RVF (right visual field, left hemisphere). It was hypothesized that LVF presentations of rotated letters would have a greater apparent duration . This was based on Hock, Kronseder, and...

It was hypothesized that LVF presentations of rotated letters would have a greater apparent duration . This was based on Hock, Kronseder, and Corcoran's (1975) demonstration that rotated letters presented in the LVF produce longer reaction times than RVF presentations on a visual comparisons task. The results were that subjects' "left" vs. "right" responses did not differ significantly for any of the conditions. Methodological considerations were cited as a possible reason for the failure to confirm the present hypo thesis.

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.

Show moreWhile academic research has begun to probe Internet users' underlying beliefs, attitudes, and purchase intent toward Internet advertising, there has been no attempt to develop an underlying theory comparing male versus female users' Internet versus print advertising content information processing. A logical place to begin examining Internet advertising is in the sphere of gender which is a critical factor in developing sales and marketing strategy and commonly used as a basis for market segmentation. Through the application of the selectivity model (Meyers-Levy 1989) and interactivity model (Bezjian-Avery, Calder, and lacobucci 1998), an attempt to predict gendered reactions to Internet versus traditional advertising is undertaken. The hypotheses drawn from the literature are tested using a 2 x 2 x 2 x 2 experimental design. The dependent variables examined are cognition, affect, and conation. The independent variables are gender, claim objectivity/subjectivity, perceived product risk category, and media. Results indicated a strong preference for objective versus subjective claims. Claim and product significantly impacted cognition and affect while gender and product significantly impacted conation. Several main and interaction effects were present and several hypotheses supported.

Three studies were designed to examine the effect of social distance on complexity of preferences (Study 1 & 3), level of linguistic categorization (Study 2), the breadth of object categories, prototypicality of anticipated activities, and coping experiences (Study 3). The results provided no support to extend the basic principle of psychological distance of CL T to a related social distance dimension.

Title: Peripheral Object Recognition in Naturalistic Scenes.

Show moreMost of the human visual field falls in the periphery, and peripheral processing is important for normal visual functioning. Yet, little is known about peripheral object recognition in naturalistic scenes and factors that modulate this ability. We propose that a critical function of scene and object memory is in order to facilitate visual object recognition in the periphery. In the first experiment, participants identified objects in scenes across different levels of familiarity and contextual information within the scene. We found that familiarity with a scene resulted in a significant increase in the distance that objects were recognized. Furthermore, we found that a semantically consistent scene improved the distance that object recognition is possible, supporting the notion that contextual facilitation is possible in the periphery. In the second experiment, the preview duration of a scene was varied in order to examine how a scene representation is built and how memory of that scene and the objects within it contributes to object recognition in the periphery. We found that the closer participants fixated to the object in the preview, the farther on average they recognized that target object in the periphery. However, only a preview duration of the scenes for 5000 ms produced significantly farther peripheral object recognition compared to not previewing the scene. Overall, these experiments introduce a novel research paradigm for object recognition in naturalistic scenes, and demonstrates multiple factors that have systematic effects on peripheral object recognition.

Learning trials were presented either in full sentences to resemble the adult learning environment, or in small increments that gradually increased to full sentences, resembling the steadily expanding processing capabilities of children. Trials were also presented randomly or ordered such that multiple examples of the same objects and verbs were presented consecutively. Language proficiency tests were administered after the lessons. A 2 (Presentation: incremental or full sentence) x 2 (Order of presentation: blocked or random) mixed ANOVA was used to analyze the data. The incremental conditions outperformed the sentence conditions on all proficiency measures. There was no significant effect of the blocking manipulation. This outcome suggests that a teaching method based on Newport's Less is More hypothesis can be advantageous in learning a foreign language.

Participants viewed video clips, each depicting an actor performing a unique extrinsic and intrinsic motion combination. One week later, they viewed a different series of retrieval video clips consisting of old (identical to encoding), extrinsic conjunction (extrinsic motion previously performed by different actor), intrinsic conjunction (intrinsic motion previously performed by different actor), and new (novel extrinsic or intrinsic motion) video clips. Participants responded "yes" to viewing the old video clips the most often, followed by conjunction video clips, and then new video clips. Furthermore, there were a greater number of "yes" event memory recognition responses for extrinsic conjunction items than intrinsic conjunction items.

In the choice condition, they produced the answer and gave a self report of how they solved it. In the no-choice condition, they were asked to use only retrieval. Naming latencies of numerals in both formats were assessed. Verbal problems were solved more slowly than digit problems in all conditions but format did not interact with problem size effect for reaction times. This latter result does not support an effect of presentation format on calculation processes. Participants also named faster digits than verbal numerals. Smaller reaction times and three times as many errors were associated with the no-choice compared to the choice condition. Mathematical aptitude also had an effect. High arithmetic skill was related to smaller reaction times, more retrieval use and fewer errors.

Younger adults were significantly worse at recognizing the conjunction items when the age of the actor was different from encoding to retrieval. This study supports the hypothesis that people are better able to recognize and distinguish others within a similar age range compared to people outside that range.

In order to challenge this paradigm, a two experiments are conducted on a chimpanzee to see if she possessed these properties. She successfully completed the cognitive tests on both experiments, thus implicating the human species as not unique in its abstractions.

Extrinsic motions are encoded as separate memory representations, making them more difficult to accurately associate with the correct actor. In the proposed experiment, I will examine the generality of this distinction in motion representation, and investigate whether the unitization of intrinsic motion with its corresponding actor occurs during reading comprehension tasks.

It’s Stock Prediction Engine functions autonomously when its skill-set suffices to achieve its goal, and it includes human-in-the-loop when it recognizes conditions benefiting from more complex, expert human intervention. Key to the system is a module that decides of human participation. It works by monitoring three mental states unobtrusively and in real time with Electroencephalography (EEG). The mental states are drawn from the Opportunity-Willingness-Capability (OWC) model. This research demonstrates that the three mental states are predictive of whether the Human Computer Interaction System functions better autonomously (human with low scores on opportunity and/or willingness, capability) or with the human-in-the-loop, with willingness carrying the largest predictive power. This transdisciplinary software engineering research exemplifies the next step of self-adaptive systems in which human and computer benefit from optimized autonomous and cooperative interactions, and in which neural inputs allow for unobtrusive pre-interactions.

Analyses revealed that when participants were given a choice of tools to solve a given problem, they were more likely to select a correct tool when options were similar in function and appearance. Additionally, participants were more likely to verbalize the need for a new tool when there was a lack of novel tool choices. However, the presence of a novel tool choice was linked to longer problem solving time. Findings are congruent with literature that suggests children possess the ability to select tools based on functional, not superficial, qualities, and can be easily distracted by the presence of novel stimuli.

Research from several developmental fields suggests that developing mechanisms of attention during the preschool years is crucial for both emotional and cognitive control. The current study shows that parental responsive behavior is important in understanding the development of voluntary attention.

We found a directional asymmetry in GC between FEF/IPS and VOC, and further identified retinotopically specific control patterns in top-down GC. This work may lead to deeper understanding of goal-directed attention, as well as the application of GC to analyzing higher-level cognitive functions in healthy functioning human brain.
