Studies assessing the reliability of the Borg rating of perceived exertion (RPE) scale for regulating exercise training intensity have reported mixed results. Differences in experimental designs and analytical techniques make it difficult to compare results. The purpose of this study was to examine the reliability of perceptually-based treadmill (TM) exercise. Eleven subjects (42.5 ± 19.5 yrs) completed a maximal test (GXT) and 3 RPEproduction trials (PT) on a TM. Each PT consisted of two 10-minute bouts where subjects selected speeds and grades to elicit an intensity equated with an RPE of 11-12 (RPE-L) and RPE of 15-16 (RPE-H). Speed and grade, heart rate (HR), oxygen uptake (V02), and ventilatory equivalent for oxygen (VE/V02) were assessed throughout the GXT and the last 3 minutes of each PT. Blood lactate concentration (BLC) was assessed at RPE-L and RPE-H during the GXT and at the completion of each PT intensity. Reliability was assessed using an ANOVA with repeated-measures, intraclass correlations, and absolute differences (ABS A) across the PTs at each intensity. No significant meangroup differences were noted in any of the physiological variables at either intensity across the PTs. Reliability coefficients were higher for the selected workload and the metabolic measures than for HR or BLC. Reliability increased across trials for all measures, and as a function of intensity for V02 (L = 0.91 & H = 0.98), HR (L = 0.60 & H = 0.84), and BLC (L = 0.50 & H = 0.64). Mean ABS A evaluated the inter-trial reliability for HR (bpm) and V02 (METS) at the low intensity PT 1 vs. PT2 = 013 bpm; A3.3 METS, PT 1 vs. PT3 = 010 bpm ; A3.3 METS, and PT2 vs. PT3 = A7 bpm; 01.6 METS and the high intensity PT 1 vs. PT2 = 011 bpm; A2.5 METS, PT 1 vs. PT3 = 011 bpm; A3.4 METS, and PT2 vs. PT3 = A9 bpm; A2.2 METS, respectively. Mean ABS A decreased for HR and V02 between PT2 vs. PT3. These data suggest that reliability of perceptually-based TMexercise varies among physiological measures and various analytical techniques, and individual variation in physiological data across PTs should be considered prior torecommending RPE for the self-regulation of exercise. / School of Physical Education

This meta-analysis investigated the efficacy of counseling to favorably change self-concept; the effectiveness of the Tennessee Self Concept Scale (TSCS) in measuring self-concept change; and whether the TSCS is consistent with other self-concept instruments in measuring self-concept change when used in the same research study. The meta-analysis inclusion criteria were: one or more psychotherapy or counseling treatments administered to the subjects; comparison of two groups, including an alternate treatment or control condition; investigated self-concept change; pre-post-test measurements of self-concept dependent variable were reported; sample was randomized and/or matched for equivalence; and sufficient information was reported to calculate or reconstruct an effect size.

In a study investigating the ability of subjects and their close friends or relatives (close-others) to recognize subject personality test results under conditions which controlled for the Barnum effect, 64 male and female undergraduate psychology students were administered the California Psychological Inventory (CPI). Each subject later attempted to choose his or her own unidentified CPI profile from among three, and a close-other of the subject independently made the same selection. It was found that 57.81% of subjects and 45.31% of close others were able to correctly identify subject profiles; these results were significant at the .0001 and .05 levels respectively. The 53.12% rate of agreement between subjects and close-others in profile selection also proved significant, p < .001. In contrast with results from a previous study (Carlson, 1985), it was found that subject self-perception and CPI description correspond to a highly significant ·degree.

The purpose of this study was to investigate the effects of a 500 Hz and 3,150 Hz one-third octave band augmentation on the speech discrimination ability of listeners with cochlear hearing impairments. The results were analyzed both within the experimental group of subjects included in the present study and in comparison with data collected on a control group of normal hearing subjects reported earlier.

Professional research project (Au.D.)--University of South Florida, 2002. / Title from PDF of title page. / Document formatted into pages; contains 34 pages. / Includes bibliographical references. / Text (Electronic thesis) in PDF format. / ABSTRACT: The self-perceived hearing aid benefit of 38 participants was examined. Of the 38 subjects, 8 were found to have an auditory processing disorder as measured by the Dichotic Sentence Identification (DSI). When compared to the non-APD subjects, there were essentially no significant differences on the APHAB or COSI outcome measures. However, two of the 5 scales of the CHPI did show significant differences. In conclusion, these results do not support the notion of APD having a negative effect on hearing aid benefit. No finding in this study was robust and although there were several trends supporting that APD may impede an individual from receiving their full potential of benefit, this finding is not necessarily so. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

Copy and recall drawings of the Rey Complex Figure obtained during the standard clinical testing of patients with well-localized epileptic foci before and after left frontal-, left temporal-, right temporal-lobe resection were re-scored blind as to lesion site using standard protocol (18 elements scored 0, 1/2, 1, or 2 based on whether they are drawn and placed correctly for a total out of 36). They were also scored for which, and how many, elements were missing, distorted, displaced, and/or repeated. Contrary to previous findings, no main effects of side or lobe or side-by-lobe interactions were found on copy and recall scores obtained either before or after surgery, and all patients' recall improved equally from pre-operative to follow-up testing. Furthermore, patients' lesion site could not be predicted on the basis of any single measure or across all measures of performance. While group differences had been found on the previously assigned scores, the between-group overlap was almost complete and the original scoring was not done blindly. These results suggest that, despite previous claims, the Rey Complex Figure, a widely-used measure of non-verbal memory, is not an effective tool for localizing neural disturbance in temporal- and frontal-lobe epilepsy patients.
