کنترل تکانه

کنترل مهاری که به آن مهار پاسخ نیز می‌گویند، یک فرایند شناختی است و به‌طور خاص‌تر، یک عملکرد اجرایی - این به فرد اجازه می‌دهد تا از انگیزه‌های خود و پاسخ‌های رفتاری طبیعی، عادی یا مسلط به محرک‌ها (a.k.a. همان پاسخ‌های پیش توان) جلوگیری کند تا رفتار مناسب تری را که با تحقق اهداف آنها سازگار است ، انتخاب کند.^[۱] خود کنترلی جنبه مهمی از کنترل مهاری است.^[۲]^[۳] به عنوان مثال، سرکوب موفقیت‌آمیز پاسخ رفتاری طبیعی برای خوردن کیک هنگامی که فرد هوس آن را می‌کند در حالی که رژیم غذایی به سر می‌برد نیاز به استفاده از کنترل مهاری دارد.

قشر جلوی پیشانی، هسته دمی و هسته ساب تالاموس برای تنظیم شناخت کنترل مهاری شناخته شده‌اند. کنترل بازدارندگی هم در اعتیاد و هم در اختلال بیش فعالی با کمبود توجه مختل می‌شود.^[۴] در بز��گسالان سالم و افراد مبتلا به ADHD ، کنترل مهاری با دوزهای کم (درمانی) متیل فنیدیت یا آمفتامین در کوتاه مدت بهبود می‌یابد.^[۱]^[۵] کنترل مهاری نیز ممکن است در طولانی مدت از طریق ورزش هوازی مداوم بهبود یابد.^[۲]^[۳]

تست‌ها

آزمون کنترل مهاری نوعی آزمایش عصب روانشناختی است که توانایی فرد را برای غلبه بر پاسخ رفتاری طبیعی، عادی یا مسلط به محرک برای پیاده‌سازی رفتارهای goal-oriented پذیرانه سازگارترکند.^[۱] برخی از آزمایش‌های عصب روانشناختی که کنترل مهاری را اندازه‌گیری می‌کنند شامل Stroop task, go/no-go task, Simon task, Flanker task, antisaccade tasks, delay of gratification tasks, and stop-signal tasksاست.

تفاوت‌های جنسیتی

زن‌ها تمایل دارند که ظرفیت پایه بیشتری برای اعمال کنترل بازدارندگی بر رفتارهای ناخواسته یا عادت داشته باشند و به عوامل متناسب با محیط تعدیل کننده نسبت به مردها واکنش متفاوتی نشان دهند.^[۶]^[۷] به عنوان مثال، گوش دادن به موسیقی به‌طور قابل توجهی سرعت مهار پاسخ را در زنان بهبود می‌بخشد، اما میزان مهار پاسخ را در مردان کاهش می‌دهد.

Data to date from studies of aging provide strong evidence of exercise-linked benefits related to task switching, selective attention, inhibition of prepotent responses, and working memory capacity; furthermore, cross-sectional fitness data suggest that working memory updating could potentially benefit as well.

Front Hum Neurosci. 8: 747. doi:10.3389/fnhum.2014.00747. PMC 4179677. PMID 25324754. Recent theory (e.g. , Temporal Self-Regulation Theory; Hall and Fong, 2007, 2010, 2013) and evidence suggest that the relation between physical activity and cognitive control is reciprocal (Daly et al. , 2013). Most research has focused on the beneficial effects of regular physical activity on executive functions-the set of neural processes that define cognitive control. Considerable evidence shows that regular physical activity is associated with enhanced cognitive functions, including attention, processing speed, task switching, inhibition of prepotent responses and declarative memory (for reviews see Colcombe and Kramer, 2003; Smith et al. , 2010; Guiney and Machado, 2013; McAuley et al. , 2013). Recent research demonstrates a dose-response relationship between fitness and spatial memory (Erickson et al. , 2011) ... The effects of physical activity on cognitive control appear to be underpinned by a variety of brain processes including: increased hippocampal volume, increased gray matter density in the prefrontal cortex (PFC), upregulation of neurotrophins and greater microvascular density ... Together, this research suggests that an improvement in control processes, such as attention and inhibition or interference control, is associated with an improvement in self-regulation of physical activity. ... Increasingly, research shows that cognitive control abilities are malleable, and that cognitive training can produce positive cognitive outcomes and improvements in daily function (Willis et al. , 2006; Hertzog et al. , 2008) that can have long-lasting effects (Rebok et al. , 2014). Approaches to cognitive training are numerous and varied; however, the relative superiority of different approaches with regard to training and transfer continue to be debated.

In particular, in both animals and humans, lower doses maximally improve performance in tests of working memory and response inhibition, whereas maximal suppression of overt behavior and facilitation of attentional processes occurs at higher doses.
