Freshwater Mussels Vary in Substrate Preference and Mobility in Pairwise Behavioral Experiments
… thesis was to use pair-wise substrate choice experiments to examine whether mussel substrate preference and mobility (horizontal and vertical) would vary in Central and East Texas mussels. This included testing 10 species under normal thermal conditions (Chapter I), as well as a case study on …

Entwine VR: A Toolkit for Creating Behavioral Experiments that Utilize Virtual Reality
… industries, the interest in VR-focused behavioral research is continuously growing. VR offers a powerful platform that allows behavioral researchers to experiment with new environments in a way that is safe, accessible, and able to be replicated. Although there are many tools that help …

Skylight Polarization Patterns as Cues for Honey Bee Orientation; Physical Measurements and Behavioral Experiments
<p>This thesis reports the results of behavioral, theoretical, and physical studies of the use of solar and skylight cues by animals for orientation. The principal features of skylight radiation which may be important for orientation are reviewed, together with previous investigations of honey bee …

The Role of Actively Created Doppler shifts in Bats Behavioral Experiments and Biomimetic Reproductions
Many animal species are known for their unparalleled abilities to encode sensory information that supports fast, reliable action in complex environments, but the mechanisms remain often unclear. Through fast ear motions, bats can encode information on target direction into time-frequency Doppler …

Men who love women : behaviour of men towards women in virtual reality : case of Eve Online
… business. The research builds up on observation, behavioral experiments and interviews along with journal articles, reports from other studies on various subjects related, books and electronic sources. The conclusions showed that there is evidence of gender discrimination in the game. Females are …

Characterizing Image Recognition Difficulty in Artificial and Biological Visual Processing
… as defined by human psychophysics. Using behavioral experiments with humans, we are able to identify images that humans struggle to recognize and investigate the prevalence of these images in datasets and their effect on model performance. To shed light on how humans are able to recognize …

The sensory mediation of symbiosis between hyperiid amphipods and salps
… column were investigated through the sensory and behavioral basis of these symbioses in three genera of hyperiids, Vibilia, Lycaea, and Phronima, which differ in the nature of their association with a common host - salps. The investigation included the description of the distribution and …

Exploring Spatial Operations of Distractor Suppression in the Sense of Touch
… vision. In this study, we conducted a series of behavioral experiments to investigate the spatial flexibility of distractor suppression mechanisms in touch. Our aim was to understand how distractor suppression is spatially deployed in the hand, determine the spatial resolution of this …

Transfer Entropy Analysis of the Interactions of Flying Bats
… is disturbed as little as possible for behavioral experiments. Following is a transfer entropy analysis approach applied to the 3D paths of bats flying in pairs. The 3D trajectories are one-dimensionally characterized as inverse curvature time series to allow for entropy calculations. In …

Hierarchical reasoning in the brain
… and computational models. First, I developed behavioral experiments to examine the reasoning behavior in dynamic environments with two hierarchical sources of uncertainty. The rational behavior necessitates evidence integration under multiple sources of uncertainty to update internal belief …

An expectation model of referring expressions
… These predictions are tested in controlled behavioral experiments, in which participants read and answer questions about short texts. The results of these experiments are shown to be consistent with a model of reference as an expectation-based computational structure with different …

The Effects of Dendro[60]Fullerene on Neurobehavioral Outcome and Cerebral Vascular Function After Traumatic Brain Injury
… C staining in the hippocampus. Through these experiments a dose response curve was conducted to compare 10, 25 and 50-mg/kg doses of DF-1. 10-mg/kg was chosen as the most effective dose to be used in the remainder of experiments. Middle cerebral artery (MCA) experiments were performed to …

Toward an Integrative Study of Human-AI Interaction
… turn to group-AI interaction through large-scale behavioral experiments. Chapter 2 investigates how social information---both direct conversation and peer behavior indicators---affects individual reliance on algorithmic decision support. The study reveals that while social information modulates …

Emergent Capabilities of Generative Models: “Software 3.0” and Beyond
… definitions” of these properties. Through behavioral experiments, we verify that our method discovers image manipulations that causally affect human memory performance. Finally, we build on this framework by incorporating a powerful new pretrained text-image semantic similarity model to …

Models and Tools for Studying Infants’ Attention
… perceptual input, and show through large-scale behavioral experiments that infant looking is well described by this model. Chapter 3 then confronts the methodological challenges of studying infant gaze empirically: to obtain and process data from a single infant in an infant looking time …

Design and control of an anthropomorphic robot finger with multi-point tactile sensation
… influences behind them. The results of behavioral experiments with the tactilely-modulated control scheme are also described. The hope is to integrate the modular finger into an engineered analog of the human hand with a complete haptic system.

In-between fixation and movement : on the generation of microsaccades and what they convey about saccade generation
… the generation of saccades. In a series of five behavioral experiments, we tested implications of the model. Predictions were derived concerning (1) the behavior of microsaccades in a given task (microsaccade rate, amplitude, and direction), (2) the interactions of microsaccades and subsequent …

Allocation of Computational Resources in the Nervous System.
… orienting phenomena, as observed from both behavioral experiments and neuronal recordings. First, we review behavioral measurements related to selective attention and discuss models that account for these data. We show that reallocation of resources emerges as a natural property of systems …

MaGKeyS : a haptic guidance keyboard system for facilitating sensorimotor training and rehabilitation
… for a stationary right hand. A set of three behavioral experiments were executed to investigate the manner in which haptic guidance, via the MaGKeyS Prototype, facilitates rhythmic motor learning. In particular, the experiments examined the independent effects of haptic guidance on ordinal …
