The Effects of Shaping and Instruction-based Procedures on Behavioral Variability during Acquisition and Extinction
… of shaping steps designed to reduce acquisition variability. Another group of subjects was instructed in the correct response topography and was told there was no penalty for attempting other sequences. The first group of subjects produced high variability during extinction despite reduced …

Person Memory: The Role of Processing Strategy, Expectancy, and Level of Incongruity in The Processing of Interindividual and Intraindividual Behavioral Variability
… Subjects were presented with a list of behavioral information about a target individual or group. Individual items varied in the level of incongruity they had to a prior expectancy and strong support was found for this hypothesis in several different experiments. Experiment 1 tested the …

Conditioned Helplessness and Human Escape Behavior
… in human subjects, and, secondly, the amount of behavioral variability that can be accounted for in terms of locus of control as measured by Rotter's Internal-External control scale (I-E scale).

The sword in the stone : lithic raw material in the Middle Stone Age at Pinnacle Point Site 5-6, southern Cape, South Africa
… time - a significant step towards understanding behavioral variability and complexity among early modern humans.

Genetic Functional Dissection of the Synaptic Output of a Dual-Function Integrating Neuron
… circuit that contributes to sensory integration, behavioral variability, generation of behavioral states, and learning. RIM releases both glutamate and the biogenic amine tyramine (~noradrenaline) and forms gap junctions with neurons that govern various aspects of C. elegans locomotion. RIM is the …

Analysis of Behavior in Populations of Swimming Microbes
… biological system to study patterns of behavioral variability. We selected motility as the behavior of interest because it is common throughout biology and can be recorded and analyzed relatively easily. We chose to work with a microbe, Tetrahymena thermophila, as a model organism for …

Neural Correlates of Audiovisual Speech Perception In Aphasia and Healthy Aging
… I tested SJ five years after her stroke with behavioral testing and determined that she is able to integrate auditory and visual information in speech. In order to understand the neural basis of SJ’s intact multisensory integration abilities, I examined her and 23 age-matched controls with …

Genetic Variation in Neurotransmitter Receptors Generates Behavioral Diversity
… Whereas diversity enriches society, extreme behavioral deviations can be pathological, so it is important to identify the causes of behavioral variability. It is clear that both the environment and genetics contribute to behavioral diversity in all animals, but the nature of the specific …

On the High-Dimensional Geometry of Neuronal Population Dynamics
… and avoidance behaviors — which induced maximum behavioral variability. We found that the visual encoding of object size is robust at the population level, despite the highly variable activity of single neurons. This robustness despite variability was due to the multi-dimensional geometry of the …

Foraging in space and time
… was the aim of this PhD-project, to show which behavioral strategies are expressed as mechanisms to cope with the constraints, which contribute to the natural selection pressure acting on individuals. For this purpose, small mammals were exposed to different levels and types of predation risk …

A study of cultural variability and relational maintenance behaviors for international and domestic proximal and long distance interpersonal relationships.
This thesis examined 228 college students' reported use of relational maintenance behaviors and strategies and their reported perception of the degree of relational satisfaction and solidarity with the relational partners they chose to identify. The study gathered extensive data with the intention …
