stress reduction course (MBSR), and were compared to a control group. There were no significant differences between the groups, meaning that the MBSR course did not affect attentional control. However, an active randomized controlled trial showed that a mobile-based mindfulness app with extensive self-assessment features may have long-term benefits for attentional control in healthy participants. Mindfulness influences non-directed attention and other things like emotional well-being. Learning Modular approaches view cognitive development as a mosaic-like process, according to which cognitive faculties develop separately according to genetically predetermined maturational timetables. Prominent authors who take a modular approach to cognitive development include Jerry Fodor, Elizabeth Spelke and Steven Pinker. In contrast, other authors such as Annette Karmiloff-Smith, Mark Johnson and Linda Smith have instead advocated taking a more interactive or dynamical systems approaches to cognitive development. According to these approaches, which are known as neuroconstructivist approaches, cognitive systems interact over developmental time as certain cognitive faculties are required for the subsequent acquisition of other faculties in other areas. Amongst authors who take neuroconstructivist approaches to development, particular importance has been attached to attentional control, since it is thought to be a domain-general process that may influence the subsequent acquisition of other skills in other areas. The ability to regulate and direct attention releases the child from the constraints of only responding to environmental events, and means they are able to actively guide their attention towards the information-rich areas key for learning. For example, a number of authors have looked at the relationship between an infant's capacity to exercise attentional control and their subsequent performance during language acquisition. Working memory capacity has been studied to understand how memory functions. The ability to predict the effectiveness of someone's working memory capacity comes from attentional control mechanisms. These mechanisms help with the regulation of goals, behavior, and outside distractions, which are all important for effective learning. Visual attentional control Our brains have distinct attention systems that have been shaped throughout time by evolution. Visual attention operates mainly on three different representations: location , feature, and object-based. The spatial separation between two objects has an effect on attention. People can selectively pay attention to one of two objects in the same general location. Research has also been done on attention to non-object based things like motion. When directing attention to a feature like motion, neuronal activity increases in areas specific for the feature. When visually searching for
