Cognitive Control Number May 11, Faculty Cognitive Control Prefrontal cortex in the anatomy of the mammalian brain is the cerebral cortex that covers the frontal lobe from the front part (Mars, 2012). Recent researchers have explained the integral link between the functions of the prefrontal cortex and the personality of an individual. The prefrontal cortex, a brain region has been indicated to have a critical role in personality expression, planning complex cognitive behaviour, moderation of the social behaviour and in decision-making. The orchestration of actions and goals in line with the internal goals are a basic role played by this brain part. Research shows that the destruction of the anterior two-thirds of this part of the brain leads to deficits in judgement, orientation, concentration, abstract ability and problem-solving ability. The prefrontal cortex performs an executive function. The executive function comprises the ability to distinguish between conflicting thoughts, the ability to differentiate good from bad, same and different, and the future consequences of current activities. It helps one to predict future outcomes, work towards a defined goal and make expectations based on individual actions and social control. The social control function ensures that one can suppress urges that may result in unacceptable social outcome if not suppressed.
The damage to the prefrontal cortex results in an executive dysfunction (Passingham & Wise, 2012). The executive dysfunction refers to the disruption of the efficacy of the executive functions. The executive functions are a group of cognitive processes that control, regulate and manage other cognitive processes. The executive dysfunction refers on most occasions to both the behavioural symptoms and the neurocognitive deficits. The situation results in mental disorders and numerous psychopathologies. It also results in long term and short term changes in non-clinical control. Goal-oriented behaviour is thus affected.

...?Analyse and evaluate the role played by top-down factors in both visual and auditory misperceptions. Please refer to relevant empirical evidence in your answer. Top-down factors are considered very important in the cognitive psychology of perception. Top-down theories suggest that what is already in the mind (what people are thinking) greatly influence the way that something is perceived to that individual. This is part of a theory known as constructivism, which suggests that cognition is what shapes the world (Eysenck & Keane, 2005). These factors play an important role in recognition, as what is already known about an object is allows us to understand who are friends and relations are from what we...

Literature analysis: Hasler, Kersten and Sweller 2007 - Learner Control, Cognitive Load and Instructional Animation

...?Hasler, Kersten and Sweller 2007 - Learner Control, Cognitive Load and Instructional Animation The in this paper were investigating how much influence learner controls had on the understanding of instructions in primary school students. The researchers used three versions of an audio visual presentation and a narration only presentation to teach children about the concepts of day and night. The three animations used were system paced, learner paced using discrete segments or learner paced using stop and play buttons. The two learner paced groups scored significantly higher than the system based groups despite the tools given to them (the stop and play buttons) only being used in a few...

...? Cognitive Processes s Cognitive Processes Introduction According to Robinson-Riegler and Robinson-Riegler (2008), learning is a natural task carried out by humans to facilitate better and more fulfilling life development. In general, human beings learn through, observation or even through other classical methods. Humans learn how to adapt to specific disciplines as well as how to ignore some unnecessary responsive stimulus though classical methods. However, in applying the available learning methods, human beings must pass through a comprehensive cognitive process. There are several types of stimulus or cognitive processes common in human growth and development....

Does the unconscious cognitive effect Cognitive Activity

...of neurological and psychological science is the power and nature of automatic thinking or unconscious response to certain cognitive activity. The unconsciousness of mind can be viewed as a shadow of conscious mind that interacts with the conscious mind without being known by an individual (Lau & Passingham, 2007). Every individual has unconscious mind, however, it does not comprise a part of brain like hypothalamus or any other part. Contextually, it undoubtedly functions in an individual’s life that affects the individual’s feeling, thoughts and decisions.

The assessment was done on the task...

Consciousness and Cognitive Control

Traditional thinkers confirm their argument by citing various activities that are controlled by individual influence such as neurological cases of extinctions, neglect, and blindsight (Wilfried Heiko and Andrea, 2010). The knowledge of possible reasons for inconsistencies in human actions will, therefore, play a vital role in understanding some of the factors that affect individual actions. Based on the presented evidence, the consciously registered events play a critical role in influencing individual behaviors and reactions to emerging activities. Traditional studies have confirmed that unconscious stimuli have a critical role in influencing individual behaviors. A classic demonstration of this case is particularly related to va...
