Available in PDF, EPUB and Kindle. Book excerpt: Four experiments were conducted on the effects of broadband, high intensity noise on human performance. In two experiments the subjects' performance was measured on a Discrimination Task, based primarily upon visual discrimination and short term memory, and in the other two experiments performance was measured on a Hand-Tool Dexterity Test. Four different noise exposure conditions were used in each experiment: control (70 dB), 120 dB, 130 dB, and 140 dB (re 0.0002 dyne/sq cm). In one experiment using the Discrimination Task, the subjects wore earplugs, and in the other, subjects wore earplugs and an earmuff with one earcup to produce an asymmetrical noise exposure at the ears. These two types of ear protectors were worn also by the subjects in the two experiments using the Hand-Tool Dexterity Task. Decrements on the Discrimination Task were obtained at the two highest noise intensities for the asymmetrical exposure and no decrements were obtained for any symmetrical exposure. With the Hand-Tool Dexterity Test, significant decrements were obtained at the noise levels of 130 dB and 140 dB with symmetrical exposure, and at 140 dB with the asymmetrical exposure. The difference in performance between the two groups was due to a different initial level of ability on the task rather than due to symmetrical versus asymmetrical exposure conditions. The results indicate that asymmetrical exposure had a greater detrimental effect on the Discrimination Task than the symmetrical exposure, while there was no differential effect on the Hand-Tool Dexterity Test. These results are discussed as a possible effect of the action of high intensity noise on the vestibular system.

Book excerpt: Human Performance provides the student and researcher with a comprehensive and accessible review of performance, in the real world and essential cognitive science theory. Four main sections cover both theoretical and practical issues: Section One outlines the perspectives on performance offered by contemporary cognitive science, including information processing and neuroscience perspectives. Section Two presents a multi-level view of the performer as biological organism, information-processor and intentional agent. It reviews the development of the cognitive theory of performance through experimental studies and also looks at practical issues such as human error. Section Three reviews the impact of stress factors such as noise, fatigue and illness on performance. Section Four assesses individual and group differences in performance with accounts of ability, personality and aging.

Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been made to determine the effects of noise on human performance. Fourteen subjects performed a memory-decision-response task in relative quiet and while listening to tape recorded noises. Analysis of the data obtained indicates that performance was degraded in the presence of noise. Significant increases in problem solution times were found for impulsive noise conditions as compared with times found for the no-noise condition. Performance accuracy was also degraded. Significantly more error responses occurred at higher noise levels; a direct or positive relation was found between error responses and noise level experienced by the subjects.
Download or read book Short term and Working Memory written by Susan E. Gathercole and published by Psychology Press. This book was released on 2001 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This special issue ponders a detailed and contemporary analysis of the theoretical underpinnings of short-term and working memory. Articles focus on short-term memory for phonological, semantic, and spatial material, on executive function and on short-term forgetting. The empirical perspectives include the neuroimaging of short-term memory, short-term memory development and the neuropsychology and neurobiology of memory, in addition to laboratory-based experimental studies. Together, these articles identify significant current models and approaches to short-term and working memory, providing a broad set of perspectives which illustrate the wide impact of working memory on the understanding of human cognition.
