“…The greater asymmetry for participants during the place condition relative to the remove condition was expected, since the increased task difficulty and greater accuracy demands of the place condition have both been linked with greater lateral asymmetries (Bryden et al, 2007;Vasconcelos & Rodrigues, 2008). Prior studies using the Grooved Pegboard Test to investigate manual asymmetries showed a greater RT when placing the pegs (higher ID) than when removing the pegs (lower ID; Bryden & Roy, 2005;Fernandes, Souza, Sales, & Apolina´rio-Souza, 2018;Lelis-Torres et al, 2017;Salvador et al, 2017). This difference observed in right-and left-hand performance among these participants may have been attributable to contralateral hemisphere specialization for voluntary movement organization and control (Elliott & Roy, 1996).…”

Association Between the Catechol-O-Methyltransferase (COMT) Val158Met Polymorphism and Manual Performance Asymmetries

Within the cognitive domain, neuroscience and cognitive psychology researchers have investigated the relationship between handedness and cognitive skills. However, there have been few studies of the three-way association between manual asymmetry, its genetic components, and cognition even though this line of research could further an understanding of asymmetry. One enzyme involved in cognitive functions related to the dopaminergic system and to the prefrontal cortex is the catechol-O-methyltransferase (COMT), and it has a trimodal activity distribution in the human population due to its functional polymorphism known as Val158Met. This study investigated whether this COMT polymorphism is associated with asymmetries in the performance of a manual dexterity task. Forty-two right-handed undergraduate students ( Mage = 25.12, SD = 5.84; 15 women, 27 men) performed two trials each of place and remove conditions of the Grooved Pegboard Test with each hand (right and left), counterbalancing the order of the initial or starting hand. We calculated the mean time to perform the task for both hands on both trials and found, as hypothesized, that the Met/Met group gave a more asymmetrical performance than the Val/Met group under the place condition because dopamine levels reduced flexible behavior for the Val/Met group. We suspect that the place condition requires greater interhemispheric connectivity, as it requires a greater cognitive flexibility, and highly asymmetrical individuals are said to be less flexible. The findings of this study suggest a significant association between the COMT polymorphism and manual asymmetry in healthy populations.

“…O Grooved Pegboard Test é composto por uma superfície com 25 orifícios, cada um possuindo uma reentrância posicionada em diferentes direções, e uma superfície côncava onde são colocados os pinos (FIGURA 1). Os pinos também possuem uma reentrância, que deve coincidir espacialmente com a do orifício para que haja encaixe (SALVADOR et al, 2017;FERNANDES et al 2018).…”

“…Inicialmente os voluntários deveriam encaixar os 25 pinos em um receptáculo, um por vez, o mais rápido possível, na ordem prescrita. Conforme realizado nos estudos de Salvador et al (2017) e Fernandes et al (2018), durante a realização da tarefa com a mão direita, o preenchimento dos receptáculos ocorreu da esquerda para a direita, de cima para baixo, já o movimento realizado com a mão esquerda no sentido inverso, da direita para a esquerda, de cima para baixo.…”

INTRODUÇÃO: A destreza manual pode ser definida como a habilidade e a facilidade na utilização das mãos, como escrever, dedilhar um instrumento musical, lançar e apanhar. A lateralidade pode ser conceituada como a preferência de utilização por um dos membros em detrimento ao outro e se confirma, por exemplo, em indivíduos destros e canhotos, influenciando nos distintos desempenhos das mãos. OBJETIVO: Comparar a destreza manual em destros e canhotos através da tarefa de colocar e retirar pinos no Grooved Pegboard Test. MÉTODOS: A amostra foi composta por 20 voluntários saudáveis, de ambos os sexos, com idade entre 18 e 40 anos, dividida em dois grupos, sendo: 5 homens e 5 mulheres de população destra e 5 homens e 5 mulheres de população canhota. Referente ao índice de dominância lateral, os indivíduos destros apresentaram índice médio de 97% e os indivíduos canhotos de 91% no Inventário de Dominância Lateral de Edimburgo. RESULTADOS: Na condição de colocar os pinos foram observadas diferenças entre as mãos dos destros [t(df=9)=-7,16; p=0,01] e dos canhotos [t(df=9)=4,80; p=0,01], o uso da mão preferida apresentou melhor desempenho relacionado ao uso da mão não preferida. Já para a condição de retirar os pinos não foram observadas diferenças entre as mãos direita e esquerda para os destros [t(df=9)=-1,96; p=0,08] e nem para os canhotos [t(df=9)=1,27; p=0,23]. Em relação ao índice de assimetria não foram observadas diferenças entre os grupos, apesar de parecer que as assimetrias se destacam em tarefas nas quais a demanda cognitiva é maior do que a demanda energética. CONCLUSÃO: O desempenho nas tarefas de destreza manual foi diferente para a mão preferida tanto para destros quanto para canhotos, sendo que a mão preferida apresentou melhor desempenho quando comparada à mão não preferida.Comparison of manual dexterity in individuals with distinct lateralityABSTRACT BACKGROUND: A manual dexterity can be defined as the skill and ease of using the hands, such as writing, strumming a musical instrument, throwing and catching. Laterality can be conceptualized as the preference of use by one of the members over the other and it is confirmed, for example, in right-handed and left-handed individuals, influencing the different performances of the hands. OBJECTIVE: To compare manual dexterity in right-handed and left-handed users by placing and removing pins in the Grooved Pegboard Test. METHODS: The sample consisted of 20 healthy volunteers, of both sexes, aged between 18 and 40 years, divided into two groups: 5 men and 5 women from the right population and 5 men and 5 women from the population left-handed. Regarding the lateral dominance index, right-handed individuals had an average index of 97% and left-handed individuals, 91%, in the Edinburgh Lateral Dominance Inventory. RESULTS: In the condition of placing the pins, differences were observed between the right-handed [t(df=9)=-7.16; p=0.01] and left-handed [t(df =9)=4.80; p=0.01], where the use of the preferred hand showed better performance related to the use of the non-preferred hand. As for the condition of removing the pins, no difference was observed between the right and left hands for the right-handed [t(df=9)=-1.96; p=0.08] and neither for the left-handed [t(df=9)=1.27; p=0.23]. Regarding the asymmetry index, no differences were observed between the groups, although it seems that the asymmetries stand out in tasks where the cognitive demand is greater than the energy demand. CONCLUSION: The performance in the tasks of manual dexterity was different for the preferred hand for both right-handed and left-handed people, with the preferred hand presenting a better performance when compared to the non-preferred hand.

This study investigated the influence of chronotype on motor behavior in a manual dexterity task performed at different times of the day. Sixteen healthy adults of each chronotype (morning, evening, and neither), as measured by the Morningness–Eveningness Questionnaire, practiced both conditions of the Grooved Pegboard Test either in the morning or in the afternoon to early evening. The “neither” chronotype (65.12 ± 7.46) was outperformed (ps ≤ .03) by both the morning (56.09 ± 7.21) and evening (58.94 ± 7.53) chronotypes when the task had higher cognitive and motor demand but was not outperformed in the task with lower demand (morning = 18.46 ± 2.11; evening = 19.34 ± 2.79; neither = 21.47 ± 2.54; p > .05). No difference between the morning and evening chronotypes was found at the different times of the day (ps > .05), suggesting that a manual dexterity task is not sufficiently demanding to be influenced by chronotype.
