Timing and Intensity Variability in the Metronomic Speech of Stuttering and Nonstuttering Speakers
- Comparison of Measures of Variability of Speech Movement Trajectories Using Synthetic Records. Lucero, Jorge C. // Journal of Speech, Language & Hearing Research;Apr2005, Vol. 48 Issue 2, p336
In speech research, it is often desirable to assess quantitatively the variability of a set of speech movement trajectories. This problem is studied here using synthetic trajectories, which consist of a common pattern and terms representing amplitude and phase variability. The results show that...
- Variability in Word Duration as a Function of Probability, Speech Style, and Prosody. Baker, Rachel E.; Bradlow, Ann R. // Language & Speech;Dec2009, Vol. 52 Issue 4, p391
This article examines how probability (lexical frequency and previous mention), speech style, and prosody affect word duration, and how these factors interact. Participants read controlled materials in clear and plain speech styles. As expected, more probable words (higher frequencies and second...
- Issues in Quantifying Variability From a Dynamical Systems Perspective. Hamill, Joseph; Haddad, Jeffrey M.; McDermott, William J. // Journal of Applied Biomechanics;Nov2000, Vol. 16 Issue 4, p407
Examines the significance of quantifying variability in dynamical systems. Approaches in evaluating movement coordination; Discussions on temporal analysis of movement; Relation between relative motion and coordination.
- Movement Variability As a Clinical Measure for Locomotion. Heiderscheit, Bryan C. // Journal of Applied Biomechanics;Nov2000, Vol. 16 Issue 4, p419
Examines the role of variability in human movement. Associations between movement variability and gait stability and unsteadiness; Significance of joint coordination in locomotion; Information on stride characteristic variability in neuromuscular diseases.
- Giftedness and variability in strategic processing on a multitrial memory task: Evidence for stability in gifted cognition. Coyle, Thomas R.; Read, Lenore E. // Learning & Individual Differences;1998, Vol. 10 Issue 4, p273
This study examined strategic variability and variability-performance relations in intellectually gifted (mean IQ = 142.31; n = 85) and non-gifted (mean IQ = 112.44; n = 81) children who received five trials on an organizational memory task. Children were presented with different sets of...
- Category variability, exemplar similarity, and perceptual classification. Cohen, Andrew L.; Nosofsky, Robert M.; Zaki, Safa R. // Memory & Cognition;Dec2001, Vol. 29 Issue 8, p1165
Evaluates the exemplar models of perceptual classification on individuals by storing exemplars in memory and classify objects in learning. Patterns of generalization to transfer stimuli; Role of category variability in classifying judgement; Effects of category variability.
- The Effect of Category Variability in Perceptual Categorization. Stewart, Neil; Chater, Nick // Journal of Experimental Psychology. Learning, Memory & Cognition;Sep2002, Vol. 28 Issue 5, p893
Exemplar and distributional accounts of categorization make differing predictions for the classification of a critical exemplar precisely halfway between the nearest exemplars of 2 categories differing in variability. Under standard conditions of sequential presentation, the critical exemplar...
- DIAGNOSING FICTIONAL DISEASES: AGE AND VARIABILITY OF TRAINING CONTENT IN CONCEPT FORMATION. Bertsch, Sharon; Sanders, Raymond E.; Hall, Rosalie // Psychological Reports;Apr2001, Vol. 88 Issue 2, p459
Investigates the effect of variability in the content used during training on concept learning, retention and transfer and the extent to which this training manipulation interacts with age. Learning about an imaginary disease by reviewing symptoms of fictional patients; Suggestion of an...
- Symmetry versus sequentiality related to prior training... Holth, Per; Arntzen, Erik // Psychological Record;Spring98, Vol. 48 Issue 2, p293
Presents a study which identifies sources of both intra- and intersubject variability in the formation of symmetry. Examination on the proportions of subjects showing symmetry after they were trained with stimuli varying their degree of sequential dependence; Recording of collateral responses...
