Abstract:
The Grooved Pegboard Test, in its standard use, has well-documented utility. However, a revised methodology needs further study, leading us to investigate whether duration of eye fixation could predict performance on different task conditions of the Grooved Pegboard Test (place and remove pegs) with the preferred and nonpreferred hands. Fifty-two right-handed undergraduate students (33 male and 19 female), with a mean age of 22.22 (±3.57) years, performed the Grooved Pegboard Test. SensoMotoric eye-tracking glasses with a binocular time resolution of 30 Hz were used to measure eye fixation. The videos were recorded in iView software, and data were analyzed using BeGaze software. The number and duration of eye fixations were statistically different with preferred and nonpreferred hands and also differed across tasks. Simple linear regression showed eye fixation duration to predict movement time in the place task (preferred hand: R2 = 31%; nonpreferred hand: R2 = 41%) and in the remove task (preferred hand: R2 = 11%; nonpreferred hand: R2 = 25%). Thus, duration of eye fixation during the Grooved Pegboard Test differentially predicted performance with each hand and on preferred and different subtests of this instrument.

Abstract:
The purpose of the study was to evaluate the capacity of an expanded set of force steadiness tasks to explain the variance in the time it takes young men and women to complete the grooved pegboard test. In a single experimental session, 30 participants (mean ± SD) (24.2 ± 4.0 yr; 15 women) performed the grooved pegboard test, two tests of hand speed, measurements of muscle strength, and a set of submaximal, steady contractions. The steadiness tasks involved single and double actions requiring isometric contractions in the directions of wrist extension, a pinch between the index finger and thumb, and index finger abduction. Time to complete the grooved pegboard test ranged from 41.5 to 67.5 s. The pegboard times (53.9 ± 6.2 s) were not correlated with any of the strength measurements or the reaction time test of hand speed. A stepwise, multiple-regression analysis indicated that much of the variance ( R2 = 0.70) in pegboard times could be explained by a model that comprised two predictor variables derived from the steadiness tasks: time to match the target during a rapid force-matching task and force steadiness (coefficient of variation for force) during a single-action task. Moreover, the pegboard times were significantly faster for women (51.7 ± 6.8 s) than men (56.1 ± 4.9 s). Participants with slower pegboard times seemed to place a greater emphasis on accuracy than speed as they had longer times to match the target during the rapid force-matching task and exhibited superior force steadiness during the single-action task.

Abstract:
Abstract: There is limited knowledge of the neurocognitive effects of the serotonin precursor 5-hydroxytryptophan (5-HTP), which is sold over-the-counter as a nutritional supplement. Animal studies have demonstrated that exogenous 5-HTP promotes the production of ectopic serotonin in dopaminergic neurons—an effect that may reduce dopamine output in these cells. Behavioral studies in humans have demonstrated specific 5-HTP induced cognitive deficits on the Iowa Gambling Task and the Tower of London task that are likely the result of reduced forebrain dopamine. However, it remains unclear if 5-HTP induced performance decrements observed on the Tower of London task were the result of a motor or cognitive impairment. The objective of this double-blind, placebo-controlled study was to clarify this point by determining if oral administration of 150 mg of 5-HTP disrupts fine motor control, as measured by the Grooved Pegboard Test. Seventy five university undergraduates received either a placebo or 5-HTP and completed the Grooved Pegboard Test. The groups did not differ in the amount of time needed to complete the place (p = 0.67) and remove (p = 0.48) components of the Grooved Pegboard Test. Therefore, 5-HTP induced reductions in performance on the Tower of London task appear to be cognitive in nature, and are unlikely to be the result of fine motor impairment (as measured by the Grooved Pegboard Test). These results also provide important safety information for 5-HTP by demonstrating that a 150 mg oral dose does not generally alter fine motor function.

Abstract:
This study investigated the relation between tests of manual dexterity and attentional functions with 49 normal, right-handed medical students (26 women, 23 men, ages 19–30 years) who were assessed with a Purdue Pegboard Test, Grooved Pegboard Test, and a Test for Attentional Performance, comprising measures of tonic and phasic alertness and divided attention. Weak to moderately high partial correlations controlling for finger size were obtained between pegboard test performance of the left hand and phasic alertness ( r = .31–.5O). Purdue Pegboard Assembly subtest scores were weakly correlated with divided attention ( r = −.39). These findings suggest that attention is an important determinant of performance for manual dexterity tests of the nondominant hand.

Abstract:
Normative values for the Finger Tapping and Grooved Pegboard Tests were developed on a sample of 360 normal volunteers stratified according to gender, three educational groups ranging from 7 to 22 years, and four age groups subdivided between the ages of 16 to 70 years. Retest reliability was estimated for both measures. The Finger Tapping Test showed significant gender differences, since women were substantially slower, particularly in the older age groups. On the Grooved Pegboard Test, a converse gender difference was noted, since women were substantially faster than men. A smaller effect with increasing age resulted, and better educated individuals performed faster. If these motor and visuomotor tests are to be applied, then stratified normative estimates need to be implemented to provide viable clinical judgements.

Abstract:
Goal-directed movements that involve greater motor variability are performed with an increased risk that the intended goal will not be achieved. The ability to estimate motor variability during such actions varies across individuals and influences how people decide to move about their environment. The purpose of our study was to identify the decision-making strategies used by middle-aged and older adults when performing two goal-directed motor tasks and to determine if these strategies were associated with the time to complete the grooved pegboard test. Twenty-one middle-aged (48 ± 6 yr; range 40–59 yr, 15 women) and 20 older adults (73 ± 4 yr; range 65–79 yr, 8 women) performed two targeted tasks, each with two normalized target options. Decision-making characteristics were not associated with time to complete the test of manual dexterity when the analysis included all participants, but slower pegboard times were associated with measures of greater movement variability during the target-directed actions. When the data were clustered on the basis of pegboard time rather than age, relatively longer times for the faster group were associated with greater motor variability during the prescribed tasks, whereas longer times for the slower group were associated with increased risk-seeking behavior (α) and greater variability in the targeted actions. NEW & NOTEWORTHY This study was the first to examine the association between decision-making choices and an NIH Toolbox test of manual dexterity (grooved pegboard test) performed by middle-aged and older adults. Significant associations were observed between decision-making choices and time to complete the test when the analyses were based on pegboard times rather than chronological age. This result indicates that decision-making choices of middle-aged and older adults, independent of age, were associated with time to complete a test of manual dexterity.

Abstract:
Clinical experience has shown that patients performing the Grooved Pegboard Test have difficulty maintaining the manualized right-to-left placement strategy with their left hand. This study sought to investigate possible differences in placement time on the Grooved Pegboard task between participants using the standardized left hand approach and a reversed manualized left hand placement strategy (i.e., left-to-right). The participants included 63 male and female undergraduate volunteers between the ages of 18 and 25 years. All participants had no history of neurologic disease/trauma, or conditions that would affect motor functioning of the right and left upper extremities. Data were analyzed using a 3-way mixed-design ANOVA. Results revealed a significant main effects for gender (F(1, 59) = 5.215, p = .026) and handedness (F(1, 59) = 6.362, p = .014). Of primary interest was the main effect for placement direction, which was not significant, F(1, 59) = .120, p = .731. No significant interaction was observed (all p > .40). Recommendations for the use of this test in applied neuropsychological settings are offered.<br>B.S.<br>Bachelors<br>Sciences<br>Psychology

Abstract:
碩士<br>國立臺灣大學<br>心理學研究所<br>107<br>Background: The Purdue Pegboard Test and the Grooved Pegboard Test are important neuropsychological tools to evaluate manual dexterity, processing speed, and multiple cognitive abilities. However, a lack of data regarding the recent Taiwanese normative and psychometric property limits their clinical utility. Objective: This study aimed to establish the North Taiwan normative data of the Purdue Pegboard Test and the Grooved Pegboard Test for normal adults aged ≥ 50 years. Psychometric properties and influences of demographical variables on the performance on the test were investigated. Method: The study recruited 242 normal adults aged ≥ 50 years in north Taiwan who were stratified by demographic variables. A subgroup of 30 participants selected additionally by stratified random sampling according to the demographic variables were administered the Digit Symbol-Coding subtest of the Wechsler Adult Intelligence Scaled-Third Edition (Taiwan version) for criterion-related validity examination. A subgroup of 30 participants, who were selected by stratified random sampling according to the demographic variables, were retested with a testing interval of at least one month later for test-retest reliability examination. Besides, 27 patients with neurocognitive disorder due to type 2 diabetes mellitus, alcohol, and neurotoxin were collected retrospectively through medical record in National Taiwan University Hospital for investigating the clinical validity. Results: Age and gender effects rather than an education one were evident in performing the Purdue Pegboard Test. Furthermore, an age effect rather than gender and education effect was evident in performing the Grooved Pegboard Test. The results also showed adequate test-retest reliability, and criterion-related, construct, and clinical validity for the Purdue Pegboard Test and the Grooved Pegboard Test. The normative data showed good representativeness, recency, and relevance. Conclusion: The Purdue Pegboard Test and the Grooved Pegboard Test have adequate reliability and validity. Based on the significant evidence of demographic effects on test performance, the present study provides age and gender demographic-corrected Purdue pegboard normative data and a referential table for percentile ranks for research and clinical settings. The present study also provides age demographic-corrected Grooved pegboard normative data and a referential table for percentile ranks for research and clinical settings.
