The Implications of Motor and Cognitive Inhibition for Hot and Cool Executive Functions: The Case of Quadrato Motor Training.

ABSTRACT: Enabling the ceasing of ongoing or prepotent responses and the controlling of interference, motor inhibition facilitates the development of executive functions (EFs) such as thought before action, decision-making, self-regulation of affect, motivation, and arousal. In the current paper, a characterization is offered of the relationship between motor inhibition and the executive functioning system, in the context of a proposed division into predominantly affective (hot) and cognitive (cool) components corresponding to neural trajectories originating in the prefrontal cortex. This division is central to understanding the effects of a specifically-structured sensorimotor movement training practice, known as Quadrato Motor Training (QMT), on hot and cool EFs. QMT's effects on crucial mechanisms of integrating different EF components are discussed.

Project description:Background:Executive functions (EFs) not only play an important role in shaping adolescent's goal-directed, future-oriented cognitive skills under relatively abstract, non-affective conditions (Cool EF), but also under motivationally significant, affective conditions (Hot EF). Empirical evidence suggest a link between EF, exercise and physical activity, specifically elite adult athletes appear to outperform amateur athletes in Cool EF; however, no previous studies have examined the relationship between Hot and Cool EFs and impulsivity during the developmentally sensitive period of adolescence comparing different types of sport (open- vs. closed-skills), and levels (elite athletes vs. amateurs). Methods:A total 86 boys and girls between 13 and 15 years of age (mean: 14.0, SD: 0.79) from different sports (track-and-field; team handball) were recruited. Participants were further divided into two groups: (a) 40 elite, and (b) 46 amateur athletes. They completed four Cool EF tasks including Trail-Making Test, Trail-Walking-Test, Flanker task, n-back-task, and one Hot EF task on Game of Dice task. Data on subjective impulsivity (UPPS Impulsive Behavior Scale; Barratt Impulsiveness Scale-15) was also collected. Results:There was a significant overall effect for expertise in favor of elite athletes (Wilks' Lambda = 0.61, F(14,69) = 3.19, p = 0.001, ?p2 = 0.393), but no overall main effect for type of sport or an interaction for expertise by type of sport. Specifically, elite athletes showed significantly better performances on dual tasks. For Hot EF, there were no main effects for type of sport, expertise level, training experience or training duration. We also found positive correlations among Cool EF and impulsivity measures, and between Hot EF and Impulsivity, but no significant relationship between Cool and Hot EF. Conclusion:The current understanding of the decisive cognitive abilities does not correspond to sporting reality, so that the tests frequently used are not sensitive enough to distinguish between elite and amateur athletes or different sports. However, it should also be remembered that the factors underlying complex sporting performance are multidimensional and are obviously difficult to trace back to selected partial aspects. Without being able to answer this question conclusively, we proposed a 4-D classification of experimental paradigms, in which we differentiate between tasks of different specificity, between Cool and Hot EF, and between task complexity, and type of sport.

Project description:BackgroundDementia is among the most common chronic noncommunicable neurodegenerative diseases. In the long term, it causes disability and loss of autonomy and independence. It is estimated that there are 35.6 million people with Alzheimer's disease worldwide. Several clinical aspects of this disease have been widely studied, but the main focus of study has been memory loss, which is one of the first symptoms. The present study proposes an innovative intervention that combines cognitive training and multisite transcranial direct current stimulation, which interferes with other clinical aspects of the subject.Case presentationIn this study, we present two subjects diagnosed with mild Alzheimer's disease. Subject 1 is an 82-year-old Brazilian Latin American woman with a high school education who was diagnosed with Alzheimer's disease 8 years ago and uses an Exelon patch. Subject 2 is an 88-year-old Brazilian Latin American woman with an incomplete primary education who was diagnosed with Alzheimer's disease 1 year ago and received medical orientation to temporarily discontinue medications for Alzheimer's disease. Both participants were subjected to intermittent cognitive training sessions and concomitant transcranial stimulation in three weekly 30-minute sessions in which a brain area was stimulated every 10 minutes for a total of 24 sessions, with a 2-month follow-up. Transcranial stimulation was applied to six different regions of the cortex: the dorsolateral prefrontal cortex bilaterally, the somatosensory association cortex bilaterally and Broca's and Wernicke's areas. Comparing the results of tests performed before and after the treatment period, a 1-point improvement was observed for both subjects on the Word Recall task of the Alzheimer Disease Assessment Scale, which evaluates symptoms related to the decline of episodic memory. Improvement in the executive functions domain was also observed through the results of the Stroop test, Victoria version.ConclusionsThe results from the two presented cases show that multisite transcranial stimulation associated with cognitive training is an effective adjuvant method for the treatment of patients diagnosed with mild Alzheimer's disease. Its effects can benefit patients' daily routines by reducing cognitive deficits by keeping intact areas active and/or compensating for lost functions. Trial registration NCT02772185.

Project description:Age-related decline in cognitive-motor multitasking performance has been attributed to declines in executive functions and physical fitness (motor coordinative fitness and cardiovascular fitness). It has been suggested that those cognitive and physical resources strongly depend on lifestyle factors such as long-term regular physical activity and cognitive engagement. Although research suggests that there is covariation between components of executive functions and physical fitness, the interdependence between these components for cognitive-motor multitasking performance is not yet clear. The aim of the study was to examine the contribution and interrelationship between executive functions, motor coordinative fitness, and cardiovascular fitness on street crossing while multitasking. We used the more ecologically valid scenario to obtain results that might be directly transferable to daily life situation. Data from 50 healthy older adults (65-75 years, 17 females, recruited in two different cities in Germany) were analyzed. Participants' executive functions (composite score including six tests), motor coordinative fitness (composite score including five tests), and cardiovascular fitness (spiroergometry), as well as their street crossing performance while multitasking were assessed. Street crossing was tested under single-task (crossing a two-line road), and multitask conditions (crossing a two-line road while typing numbers on a keypad as simulation of mobile phone use). Street crossing performance was assessed by use of cognitive outcomes (typing, crossing failures) and motor outcomes (stay time, crossing speed). Linear mixed-effects models showed beneficial main effects of executive functions for typing (p = 0.004) and crossing failures (p = 0.023), and a beneficial main effect of motor coordinative fitness for stay time (p = 0.043). Commonality analysis revealed that the proportion of variance commonly explained by executive functions, motor coordinative fitness, and cardiovascular fitness was small for all street crossing outcomes. For typing and crossing failures (cognitive outcomes), the results further showed a higher relative contribution of executive functions compared to motor coordinative fitness and cardiovascular fitness. For stay time (motor outcome), the results correspondingly revealed a higher relative contribution of motor coordinative fitness compared to executive functions and cardiovascular fitness. The findings suggest that during cognitive-motor multitasking in everyday life, task performance is determined by the components of executive functions and physical fitness related to the specific task demands. Since multitasking in everyday life includes cognitive and motor tasks, it seems to be important to maintain both executive functions and physical fitness for independent living up to old age.
