Description

You need the ability to shift the focus of your attention from one object to another, depending on the situation. There are early-selection and late-selection models to propose what might draw your attention to a particular target and research has identified several brain areas that are involved in shifting attention. These processes of maintaining and shifting attention are important in your daily life, such as when driving, and they have clinical implications. Attention-deficit hyperactivity disorder (ADHD) is considered a disorder that impacts the ability to maintain or shift attention. Some consider ADHD both an overdiagnosed and underdiagnosed neurodevelopmental condition. Diagnosis can be challenging, but it is thought to affect about 7% of children and adolescents worldwide and about 11% of the population in the United States. Understanding attention and the biological basis of how to shift or maintain that attention may be the first step to treating the underlying cause of this disease.

Related to attention is the idea of consciousness. These terms are sometimes used interchangeably, but they can mean very different things. In the broader sense, consciousness is that emergent property that is fundamental to human existence and potentially separates us from other living things. Researchers have struggled to define and study consciousness, generally breaking it down into easy problems, which can probably be addressed with current research techniques, and hard problems, which are the “how” and “why” questions that cannot be addressed in an obvious way by today’s techniques.

For this Discussion, you will summarize the different models of attention and the brain areas involved. You will consider ADHD and the common pharmaceutical treatment. Finally, you will describe consciousness and the how researchers define the easy and hard problems of consciousness.  

To prepare:

Review this week’s Learning Resources, focusing on the models and types of attention and the regions of the brain involved in attention and shifts of attention. As you read about attention, consider the efficacy of multitasking. Finally, be sure you can differentiate between the easy and hard problems of consciousness.

By Day 3

Post a response to the following:

Describe the early-selection and late-selection models of attention.

Describe the brain areas involved in attention.

Differentiate between the areas involved in voluntarily shifting attention and those involved in reflexive shifts of attention.

Describe ADHD and explain a pharmaceutical and non-pharmaceutical treatment for the condition. Include an assessment of the effectiveness of each treatment.

Define consciousness and differentiate between the easy and hard problems of consciousness.

Models of Attention

Attention refers to one's awareness of specific stimuli. Occasionally most persons suffer
from the condition of hyperactivity and failure to pay attention effectively called ADHD. Persons
who have ADHD have trouble remembering things, are irritable, have reduced concentration,
and quickly get distracted. The brain is the chief organ responsible for attention. Moreover,
consciousness refers to a person's ability to be aware and respond to one's internal and external
surroundings. Attention and conscience are both useful for any healthy individual. There are
various treatments used to treat ADHD, which may be pharmaceutical like amphetamine or nonpharmaceuticals, such as psychotherapy or skills training.
The Early and Late Models of Attention
The selection models of attention explain how certain stimuli capture one's attention. The
selection models are utilized by neuro-researchers to explain when proposing when stimulus
information is attended to. Broadbent was a very renowned researcher who put forward the early
and late selection theories. The primary difference between the two approaches is that the early
selection theory proposes that physical aspects of stimuli are attended to while the late model
posits that the semantic aspects are the most significant determinants of an individual's present
focus of attention. In the early selection theory...

Excellent! Definitely coming back for more study materials.
