Selection of exercise intensity using perceptual cues during television distraction
The selection of exercise intensity during television distraction was studied in 20 highly-fit males (VO2peak: 63.2 +/- 10.7 ml·kg -1·min-1) between the ages of 28 and 45 years. It was hypothesized that the perception of exercise intensity during cardiovascular exercise would be influenced by …

Perceptual Cues and Subjective Organization in a Virtual Information Workspace
… retrieval; however, the potential benefits of perceptual depth cues have not been systematically studied.</p> <p>The present study used a computer task to examine the effectiveness of three types of virtual desktops. A two-dimensional (2D) virtual desktop display, lacking in the cues that give …

On the effects of masking of perceptual cues in hearing-impaired ears
… subject’s strategy? From the 3DDS findings of perceptual cues (Li and Allen 2011; Li et al. 2012), results from two perceptual masking experiments (Li and Allen 2011; Kapoor and Allen 2012), and analysis of work by Han (2011) and Trevino and Allen (2013), we generalize the errors made by an HI …

Perceptual cues of consonant sounds and impact of sensorineural hearing loss on speech perception
… based on the information of identified speech cues. A psychoacoustic method, named three-dimensional deep search (3DDS), is developed to identify the perceptual cues of consonant sounds in natural speech. Unlike the conventional method of synthetic speech, which requires a prior hypothesis …

A cross-linguistic study of certain temporal features of speech in stuttering and nonstuttering children
… temporal coarticulatory speech features in the perceptually fluent speech of 120 South African children. The aim was to test, in a limited way, the postulate that stuttering may be essentially a disorder of speech timing. Comparisons were made between English- and Afrikaans-speakers, between …

Understanding language through visual imagination
… way children learn language through exposure to perceptual cues. The model generates videos by sampling the visual features of objects described in the target sentences over time. The evaluation results show that the model can reliably generate videos for sentences describing multiple concurrent …

A verification experiment of the second formant transition feature as a perceptual cue in natural speech
… the acoustic features that are used as perceptual cues in human speech perception. A brief history of this research is given, with emphasis on one important feature, the second formant (F2) transition. A review of historical arguments made for and against its role in the perception of …

An ecological perceptual aid for precision vertical landings
… which often involve the loss of outside visual perceptual cues or the control of flight parameters within tight constraints. These challenges are often associated with a high mental workload, therefore, a precision landing aid that addresses and helps to mitigate these challenges, and reduce …

Display Techniques in Information-Rich Virtual Environments
… information types. This research explores the perceptual and usability impacts of data representations and layout algorithms for the next-generation of integrated information spaces. We propose Information-Rich Virtual Environments (IRVEs) as a solution to challenges of integrated information …

The Effects of Facial Cues on Consumer Judgment and Decision-Making
… dissertation investigates the roles of facial cues in consumer behavior. Specifically, the research examines the effect of facial structural resemblance, facial expressions, and other perceptual cues—in both individual and group settings—on consumer judgment and decision-making. Essay 1 …

Techniques for understanding hearing-impaired perception of consonant cues
We examine the cues used for consonant perception and the systematic behavior of normal and hearing-impaired listeners. All stimuli were presented as isolated consonant-vowel tokens, using the vowel /A/. Use of low-context stimuli, such as consonants, aids in minimizing the influence of some …

Verification of feature regions for stops and fricatives in natural speech
The presence of acoustic cues and their importance in speech perception have long remained debatable topics. In spite of several studies that exist in this eld, very little is known about what exactly humans perceive in speech. This research takes a novel approach towards understanding speech …

Speech rhythm: the language-specific integration of pitch and duration
… (ii) acknowledges the role of several acoustic cues, and (iii) explores whether the relative significance of these cues differs between languages. This thesis, the originality of which derives from its adoption of these three perspectives combined, indicates new directions for progress. A series …

A theory of speech perception in normal and hearing-impaired ears
… We aim to study speech perception and decode perceptual cues in speech by conducting psychoacoustic experiments on several subjects by presenting them with nonsense consonant-vowel (CV) syllables in various kinds of masking noise at di fferent signal-to-noise ratios (SNRs). Our research with a …
