Повний текст джерелаThe vigilance decrement is the decline in performance over time that characterizes tasks requiring sustained attention. Resource Theory proposes that the vigilance decrement is due to information processing assets that become depleted with use. Resource theorists must thus identify these assets and the process of how resources are depleted and replenished. The Microlapse Theory of Fatigue (MTF) identifies the resource that is depleted when performing a sustained attention task as the central executive attentional network. The depletion of the central executive network resource results in microlapses or brief gaps in attention that prevent the perception and processing of information. The MTF can explain various effects in the sustained attention literature regarding how resources are depleted. However, the MTF alone cannot explain the event rate effect or the motivation effect because it does not include replenishment mechanisms that can occur during a sustained attention task. To better understand the process of replenishment, participants were assigned to varying event rate and external motivation conditions in a novel paradigm that could measure the perceptual processing of a trial over time. These stages of processing included when participants looked at the first stimulus, looked at the second stimulus, and responded. In Experiment 1, it was found that the vigilance decrement was more severe for faster event rates, consistent with Resource Theory and counter to the MTF. In Experiment 2, the event rate effect was replicated, but unexpectedly, external motivation did not impact the vigilance decrement. In both experiments it was found that for the stages of processing that involved looking at the stimuli, more slowing was found as event rate increased. Additionally, more slowing was detected earlier in the processing of a trial than later. These results supported the process of microlapses inducing the vigilance decrement due to not having enough time to perceive, encode, and respond to stimuli, as described by the MTF. It was interpreted that the interaction between time-on-task and event rate was due to opportunistic breaks that occurred more frequently in slower event rate conditions. The finding that more slowing occurred earlier in processing was interpreted as evidence for internal rewards related to learning impacting the speed of processing a trial. To explain these findings, I propose the Microlapse Theory of Fatigue with Replenishment (MTFR) a process model similar to MTF, but that includes additional replenishment mechanisms related to opportunistic rest periods and internal rewards. The Microlapse Theory of Fatigue with Replenishment (MTFR) closely correlates to the empirical data and is an important step forward in the effort to build a comprehensive model of sustained attention.

Повний текст джерелаIntrodução: O Transtorno de déficit de atenção e hiperatividade (TDAH) é o transtorno infantil mais prevalente do mundo e se relaciona com deficiências de catecolaminas em testes físicos, bioquímicos e cognitivos; por outro lado alguns exercícios são conhecidos como potentes estimuladores de catecolaminas, tanto central quanto e perifericamente. Objetivo: Testar a hipótese das catecolaminas (CA) centrais como as responsáveis pelo aumento na velocidade de reação vistas após atividades físicas e medir o impacto que esforços físicos agudos supra limiares apresentam na atenção sustentada de 25 crianças diagnosticadas com TDAH, conforme os critérios do DSM-IV. É possível que a prática desportiva possa ser positiva no manejo dos sintomas de TDAH. Método: As crianças foram divididas entre usuárias (US) e não usuárias (NUS) de Metilfenidato (MTP), os grupos foram comparados quanto a aspectos antropométricos, cognitivos e fisiológicos assim como os efeitos crônicos da droga, sobre a cognição, imediatamente após atividades físicas intensas. Resultado: A performance cognitiva após esforços físicos não foi, de maneira relevante, modificada pelo MTP. Observamos melhoras significativas no tempo de resposta, assim como normalização da impulsividade e das medidas de vigilância por meio do CPT teste. Conclusão: Estes resultados sugerem que a melhora cognitiva usualmente vista após a prática desportiva não são CA dependentes; adicionalmente exercícios físicos podem ser de auxílio no alívio dos sintomas de TDAH.
Attention deficit hyperactivity disorder (ADHD) is related to a deficiency of central catecholamines (CA) in cognitive, biochemical, and physical tests, and pharmaceutical intervention may have no effect if it is not accompanied by changes in the environment. The objective of our study was to test the hypothesis that central CA are responsible for the increase in speed reaction seen after physical activity (PA) and to measure the impact of high intensity PA on the sustained attention of 25 children diagnosed with ADHD consistent with the Disease Statistical Mental-IV (DSM-IV) criteria. It is possible that practicing sports assists in the management of the disorder. The children were divided between users (US) and non-users (NUS) of methylphenidate (MTP), and the groups were compared to evaluate the effect of the drug on cognition after PA. Post-exercise performance on Conner’s Continuous Performance Test-II (CPT) was not affected by MTP, we observed significant improvements in response time, and we saw normalization in the impulsivity and vigilance measures. These results suggest that the improvements in cognition after physical effort are not CA dependent. Additionally, our results suggest that children’s attention deficits can be minimized through PA irrespective of treatment with MTP. Additional studies are necessary to confirm that exercise mitigates the harmful symptoms of ADHD.

Повний текст джерелаThe overarching aim of this dissertation is to examine the role of human motion processing complex, MT+ during sustained perception and attention. MT+ is comprised of sub-region MT, which processes motion in the contralateral visual field (i.e., left hemisphere MT processes motion in the right visual field and vice versa), and sub-region MST, which processes motion in both the contralateral and ipsilateral visual fields. Whereas previous transcranial magnetic stimulation (TMS) research has provided compelling evidence that region MT+ is necessary for low-level motion processing, Chapter 1 describes an experiment testing whether the sub-region MT is necessary for contralateral low-level motion processing. Chapter 2 describes an experiment that dissociates low-level sensory attentional modulation in MT+ from high-level attentional control processing in the parietal cortex (i.e., during sustained attention). Chapter 3 describes an experiment investigating the role of MT+ during aesthetic processing when viewing visual art. Importantly, this experiment tests whether the aesthetic is tied to not only low-level motion processing in MT+ but also high-level processing in frontal regions. Taken together, the results across the three experiments provide novel evidence for the role of MT+ during low-level motion processing during sustained perception and attention. Moreover, these low-level motion processing effects together with the observed high-level processes in frontal-parietal regions provide neural mechanisms for the cognitive processes of sustained perception and attention

Повний текст джерелаThe purpose of this project was to gain more knowledge about the effects of normal aging on sustained attention ability and attentional control mechanisms underlying this ability. To that end, we combined the use of behavioral, subjective and electrophysiological (event-related potentials) measures. Behavioral results evidenced differential effects of age on sustained attention ability according to the approach used: deterioration in detection tasks, and preservation in inhibition tasks. Electrophysiological data evidenced several special features of seniors regarding the recruitment of attentional control mechanisms in a situation of sustained attention: overall greater activation of these mechanisms, stable or increased activation of these mechanisms over the course of the task, and a more frontal topography of the regions underlying these mechanisms

Повний текст джерелаIntroduction: Sustained attention is known to be dysfunctional in psychotic disorders. Sustained attention is the ability to remain focused on a specific time-locked stimulus within a task. We aimed to determine whether there are specific group differences between CON and three psychotic disorders: SCZ, MPD and BPD, then to determine differences between these psychotic disorders. This included differences in behavioural performance and prominent electrophysiological event-related potential (ERP) wave components during cueing and target processing of a visual sustained attention task. Further we aimed to characterize ERP waveform component relationships across and within these groups for demographics, substance use, behavioural performance, and clinical variables, the last limited to the psychotic groups. Lastly, we investigated the effects of prescribed medications on ERP wave components within the psychotic groups. Methodology: 103 participants (29 schizophrenia (SCZ), 28 bipolar disorder with a history of psychosis (BPD), 21 methamphetamine-induced psychotic disorder (MPD), and 30 controls (CON)) underwent electroencephalography (EEG) record while completing a visual continuous performance task. Participants were presented with 60 trials with three consecutive S’s, the presentation of the third S required a behavioural response. Prominent ERP waveform components were extracted from cues and target stimulus. Group differences were determined by ANOVA with Bonferroni post-hoc correction or multivariate Kruskal-Wallis test dependent on data distribution. Relationships between ERP wave components were determined appropriate with Spearman’s Rank order correlation analyses.

Повний текст джерелаPrésentement, le développement différencié des sous-composantes de l'attention et des fonctions exécutives durant les âges préscolaires n'est pas entièrement compris. Bien qu'il existe un grand corps de recherche portant sur la maturation de l'attention et les fonctions exécutives dans les enfants d'âge scolaire, il reste encore beaucoup à apprendre concernant l'émergence de ces compétences chez les enfants d'âges préscolaires. Il est nécessaire de délimiter les compétences et les carences attentionnelles dans le développement typique pour qu'on puisse utiliser ces informations pour mieux comprendre et définir les trajectoires des habilités attentionnelles dans le développement atypique; précisément, dans les troubles du développement neurologique qui se caractérisent par des difficultés attentionnelles. En utilisant des paradigmes informatiques adaptés, la présente étude a examiné le développement de l'attention soutenue, l'inhibition et la mémoire de travail visuelle et auditive chez soixante-dix enfants au développement typique âgés de 3 à 6 ans. Les résultats montrent que des améliorations de performance liées à l'âge ont émergé à travers les trois tâches cognitives et les modalités visuelle et auditive, suggérant que les paradigmes adaptés utilisés sont suffisamment sensibles pour capturer des variations de performance associées aux changements développementaux.

Повний текст джерелаThe influence of attention in decision making processes is usually evaluated using two-alternative choice tasks in which the subjects react relying on detection and discrimination of two discrete stimuli. The possibilities of manipulating attentional demands in this kind of task is relatively restricted. The experimental design employed in the present experiments aimed at providing ways to manipulate the attentional demands during performance of an auditory task. This was achieved by presenting variable sequences of non-informative 6 kHz beeps, bilaterally, followed by one distinctive (either 3 or 10 kHz) informative beep presented either (1) bilaterally such that the frequency identifies the required response (Experiment 1) or (2) unilaterally such that the place of presentation identifies the required response (Experiment 2). In Experiment 1 data showed a decrease in both reaction times for target stimuli and percentage of comission errors as a function of the number of non-informative stimuli. These effects occurred early in training for both, 3 and 10 kHz target stimuli, and only for 10 kHz target stimulus after reversal of training. Interestingly, reaction times for 10 kHz target stimuli were longer relative to those seen for 3 kHz target stimuli. In contrast, reduction of the percentage of comission errors was stronger in trials using 10 kHz target stimuli. In Experiment 2 reaction times increased as a function of the increase in the number of non-informative stimuli. In addition, reaction times for 10 kHz target stimuli presented in the left side were longer as compared to both 10 kHz target stimuli presented in the right side and 3 kHz stimuli presented in both sides. Congruently, a smaller percentage of correct responses and a greater percentage of comission errors were seen when the 10 kHz target stimuli were presented in the left side. The percentage of correct responses and reaction times reduction were greater in the Experiment 2 as compared to Experiment 1, suggesting that in the present experimental conditions, identification of the place for stimulus presentation is prompter as compared to the difference in the frequency of the target stimuli. Together these results show that engagement and maintenance of attentional resources along time vary as a function of the peripheral and simbolic nature of the target stimuli. The frequency of target stimuli presented after a variable sequence of non-informative stimuli also interferes in performance of the subject
