“…In addition, our data indicated that the SMA may be one of the key cerebral regions for attention-dependent quantification of time perception, though further neuroimaging studies are required to verify this source localization result in this study. The current findings improve our understandings of timing mechanisms and lay the ground for the investigation of patients with time perception deficits, such as attention-deficit hyperactivity disorder and Parkinson’s disease [41,42]. …”

The present study examined the neural mechanisms of attention modulation on timing using ERP and sLORETA measurements in a dual-task paradigm. We parametrically varied the attention to the durations of a 1000-Hz pure tone and further localized the cortical regions that were sensitive to the attention modulation on timing. Results demonstrated that the attention modulation might happen at early stage, approximately 200 ms after stimulus presentation. The P2 component at frontal area served as an early neural correlate of attention effects on timing. More importantly, the contingent negative variation (CNV) appeared at fronto-central area was sensitive to the attention effect. In addition, the supplementary motor area (SMA) was assumed to be one of the key regions for selectively attending to and estimating time. These findings provide temporal and spatial correlates of attention-modulated time processing and potentially help to investigate the neural mechanisms of patients with time perception deficits.

OBJETIVO:comparar os achados da avaliação comportamental do processamento auditivo temporal em crianças com e sem Transtorno do Déficit de Atenção com Hiperatividade.MÉTODOS:participaram desse estudo 30 crianças na faixa etária de 8 a 12 anos, sendo 15 do grupo controle e 15 do grupo pesquisa, com limiares audiométricos dentro dos padrões de normalidade. Como procedimentos foram realizados os testes temporais de padrão de frequência e de duração.RESULTADOS:na comparação entre o grupo controle e grupo pesquisa em ambos os testes - padrão de frequência e padrão de duração foram verificadas diferenças significantes entre os grupos, sendo que o grupo pesquisa apresentou resultados alterados em sua maioria, enquanto que todas as crianças do grupo controle apresentaram resultados normais. Foi possível observar ainda que todas as crianças de ambos os grupos tiveram resultados inferiores para o Padrão de Duração quando comparado aos resultados do Padrão de Frequência e.CONCLUSÃO:a avaliação comportamental do processamento auditivo temporal de crianças com e sem Transtorno do Déficit de Atenção com Hiperatividade, mostrou que os sujeitos com Transtorno do Déficit de Atenção com Hiperatividade apresentaram alterações, enquanto que o grupo sem Transtorno do Déficit de Atenção com Hiperatividade resultados normais em ambos os testes. O presente estudo possibilitou um maior conhecimento da via auditiva central das crianças com e sem Transtorno do Déficit de Atenção com Hiperatividade, porém, outros estudos ainda se fazem necessários, principalmente na literatura nacional, a fim de se conhecer melhor o funcionamento do processamento auditivo dessas populações.

Objectives: Children with attention-deficit hyperactivity disorder (ADHD) may have deficits in time perception, as assessed by the time estimation task and the time reproduction task, however its age-related trajectory is not yet determined. Therefore we examined the correlation between accuracy of time perception tasks and age, and the association between accuracy of estimation tasks and reproduction tasks.Methods: Sixty-three patients with ADHD, aged 8 to 18 years tested the tasks for five time durations (2, 4, 12, 45, and 60 seconds). Accuracy of tasks was assumed differences (absolute values) between raw results of tasks and original time durations. Spearman's correlation analysis was performed to determine correlation between accuracy of time perception tasks and age. Multivariate regression was used to determine the association of accuracy of estimation tasks with accuracy of reproduction tasks.Results: Age showed correlation with accuracy of estimation tasks, but not with that of reproduction tasks. We observed that the higher the accuracy in 12, 45, and 60 seconds duration time reproduction, the higher the accuracy in longer seconds duration time estimation.Conclusion: Age was correlated with time estimation accuracy whereas there was no impact on time reproduction accuracy. Association of each of the two time perception tasks, particularly in longer time duration, suggested specific impairments in time perception.
