Summary of Neuropsicología de la Atención. Clase 5.

00:00:00 - 00:35:00

This video is about neuropsychology and the attentional process. It discusses how people with attentional deficits cannot orient their attention towards the left or the right side of the screen. The video also discusses attentional neglect and attentional simmetria.

• 00:00:00 This fifth video in the Neuropsychology of Attention series covers the cognitive processes involved in attention. We start by introducing the topic with a brief overview of the previous four videos. We then proceed to study the cognitive processes involved in attention by looking at the different stages it goes through. We explore the role of attention in memory, motivation, emotion, and language. We end the video by discussing the importance of attention and how it is essential for focusing on a specific task.
• 00:05:00 This video discusses the concept of attention, and how we can control it. It covers the idea that attention is a voluntary process, and that we are able to focus on one thing at a time. It also discusses the concept of focus, and how we can select which stimuli to pay attention to. Finally, it covers the idea of attentional selection, and how we are able to focus on specific pieces of information while ignoring other stimuli.
• 00:10:00 This video discusses the neuropsychology of attention, focusing on the attention system's hierarchical structure and its various regions. It covers different models of attention, as well as multiple definitions of the term "attention." The focus of this class is on the neurological structure of attention, and the various aspects of its operation that are covered include alertness, vigilance, and selective focus. The class also discusses the concept of attentional selectivity, which is defined as the ability to process information in a focused way while ignoring distractions. This video also covers the concept of attentional vigilance, which is the ability to maintain focus on a task for a prolonged period of time under conditions of distraction. Finally, the video discusses the concept of attentional control, which is the ability to manage information and stay focused on a task.
• 00:15:00 The video discusses the neuroscience of attention, discussing the three main processes involved in attention: cognitive control, selective attention, and vigilance. The video also discusses two models of attention, the Broadbent-Nordman model and the Model of Sensory-Motor Integration. The Model of Sensory-Motor Integration understands attention as a set of neuropsychological processes to focus consciousness on the relevant part of the external environment while suppressing the instruction of distracting stimuli. The video goes on to discuss the role of arousal in attention and how it affects cognitive control, selective attention, and vigilance.
• 00:20:00 The video discusses the two main attention systems in the brain: the arousal system and the attentional selectivity system. The arousal system is responsible for keeping attention active, while the attentional selectivity system decides which stimuli to attend to. The video explains that these two systems work together to keep attention focused on what's important. The video also discusses the role of different regions in the brain in attentional vigilance and attentional selection.
• 00:25:00 This class focuses on the neuropsychology of attention, covering topics such as the parietal cortex and frontal regions. It discusses how tasks that require vigilance, such as continuous execution, increase activity in the right frontal parietal network. Clinical data also suggest that damage to the frontal left changes the ability of family members to maintain voluntary attention. Parietal damage also affects orienting functions, and frontal lobe damage alters the ability to detect and respond to stimuli in a covert manner. Finally, we discuss the executive attention network, which plays a role in tasks such as response inhibition, conflict resolution, and stimulus selection.
• 00:30:00 The video discusses neuropsychology, focusing on attentional deficits. It discusses the model of Posner and Petersen, which states that the left hemisphere is better at attending to objects in the right visual field and the right hemisphere is better at attending to objects in the left visual field. The video also discusses attentional neglect, which is a disorder in which a person cannot attend to or process new stimuli effectively. Finally, the video discusses attentional simmetria, which is the pattern of brain activation that occurs when the left and right hemispheres are working together.
• 00:35:00 This video is about neuropsychology, and it covers the attentional process. The main point is that people with attentional deficits cannot orient their attention towards the left or the right side of the screen. Relative to other types of neglect, this may be more successful, but it can still be confusing because the term "attentional deficit" is used for a variety of different problems, such as alexia or praxis/constructive attention disorder. In this lesson, we're not interested in all of these classification schemes, but we do want to understand the concept of a patient with an attentional deficit not being able to disengage and orient their attention towards the lateral side of the lesion, which is typically on the right side. This is usually classified as a CDH (central deviance syndrome). We'll look at one disorder that is associated with sustained attention, and we don't need to know the full picture since it's going to be seen repeatedly throughout our career. Patients may also take our course material, which is a deficit that impacts executive function. This can lead to difficulties with task completion, as well as impaired working memory and executive function. We'll close the class with an invitation to join us for group sessions to discuss any questions
