A psychophysical study of visual texture
… his scheme, there seems to be a complete lack of psychophysical investigation of this notion in the literature. The above considerations led to the formulation of the present problem. Specifically, the relationship between a set of physical measure· operations and a set of observer responses on a …

Presentness: Developing Presence Through Psychophysical Actor-Training
… here and now as shaped by the performer’s psychophysical engagement with his or her surrounding. It is, thus, a tangible aspect of presence that can be enhanced and developed through training. Presentness developed through training is an acting skill although it does not necessarily …

The neural and psychophysical bases of memorability
… the first characterization of the neural and psychophysical bases of memorability. First, I show that memorability is highly consistent in the domain of face images, despite their similar perceptual features and same basic-level category, and examine what facial attributes are predictive of …

An investigation of team lifting using psychophysical methods
… affect the results of team lifting tasks. The psychophysical methodology has been used for almost 30 years in trying to determine the maximum acceptable weight of lift for industrial workers. Though two previous studies of team lifting used the psychophysical approach, no effort was made to …

The Correlation Between Biomechanical Loads and Psychophysical Ratings
… about how subjective ratings, the core of the psychophysical methodology, relate to physical (biomechanical) loads. A fundamental assumption of this method is that humans are capable of estimating biomechanical and physiological loads that are placed on the body. Based on this assumption, …

The psychophysical and physiological assessment of cochlear-origin tinnitus
A clinical evaluation protocol of cochlear-origin tinnitus that included psychological and physiological tests was proposed and administered to seven subjects. Among several components of the results, the combination of the Distortion Product Otoacoustic Emission(DPOAE) level, Input/Output slope, …

A psychophysical investigation of quantum cognition: An interdisciplinary synthesis
… on the applicability of quantum cognition to psychophysical perceptual processes. Specifically, we experimentally tested several a priori hypotheses concerning 1) constructive measurement effects in sequential perceptual judgments and 2) noncommutativity in the measurement of psychophysical …

Factors affecting color appearance and measurement by psychophysical methods
… magnitude estimation and magnitude production psychophysical methods. Changes in color appearances resulting from variations in correlated color temperature of adapting illumination, luminance factors of samples, illuininance, and surround induction conditions were scaled by a group of seven …

Psychophysical aspects of clinical perimetry: studies in ageing and disease
… overall hypothesis that through optimising the psychophysical task, contrast sensitivity can be determined more accurately. Methods: Subjects with normal ocular health and patients with glaucoma were recruited to undertake psychophysical testing using a variety of instruments. Normal subjects …

Ergonomics of single-handed pulling : a biomechanical and psychophysical assessment
The description of biornechanical events measured during manual materials handling (MMH) activities has been a major focus for ergonomists attempting to understand the relationships between performance factors and injury mechanisms. Pulling exertions, while being frequently observed in occupational …

A psychophysical investigation of audio-visual timing in the millisecond range.
The experiments described in this thesis use psychophysical techniques and human observers to investigate temporal processing in the millisecond range. The thesis contains five main sections. Introductory chapters provide a brief overview of the visual and auditory systems, before detailing our …

Mechanical and psychophysical studies of surface wave propagation during vibrotactile stimulation
… for precise spatial localization. A series of psychophysical experiments was conducted using a three-by-three array of motors in which the ability of subjects to localize the point of stimulation in an array was determined at each of the three body locations. The results from these experiments …

Emotional Impacts on Driver Behavior: An Emo-Psychophysical Car-Following Model
This research effort aims to create a new car-following model that accounts for the effects of emotion on driver behavior. This research effort is divided into eight research milestones: (1) the development of a segmentation and clustering algorithm to perform new investigations into driver …

Psychophysical assessment of load-carrying in internal and external-frame backpacks
The psychophysical method of adjustment was used to determine whether slight changes in load position and comfort could have significant effects on the maximum backpack load acceptable to subjects. Four males and four females, who were accustomed to walking with backpacks, were given 15 minutes to …

Predicting Shoulder Fatigue for Long Durations Using Psychophysical Measures Obtained from Short Trials
… unique analysis techniques used to look at the psychophysical data may prove useful for further investigation into predictive verification. A generalized mathematical model, a type of approach, was also developed to represent changes in the psychophysical measures over time. This research can …
