Visual Agnosia

Visual Agnosia

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...

Steps in the Modeling Process

Steps in the Modeling Process

Albert Bandura's theory of observational learning identifies four critical processes: attention, retention, motor reproduction, and reinforcement or motivation.
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...

Implicit Memories

Implicit Memories

Implicit memories, also known as non-declarative memories, are long-term memories that function outside of conscious awareness. These memories influence behavior and skills without explicit knowledge. This type of memory is evident in tasks like playing tennis, snowboarding, and texting. Implicit memory has three subsystems: procedural memory, conditioning, and priming. This type of memory is essential in various activities, from everyday tasks to specialized skills.
One key aspect of implicit...

Repressed Memory

Repressed Memory

Repressed memories are a psychological phenomenon where memories of traumatic events are unconsciously blocked from a person's awareness. This process occurs as a defense mechanism, protecting the mind from the emotional impact of distressing or painful experiences. For example, a person who has experienced childhood trauma may grow up with no conscious recollection of the event. In such cases, the memories are thought to be buried deep within the subconscious, inaccessible to the conscious...

The Representativeness Heuristic

The Representativeness Heuristic

The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

Nonconscious Mimicry

Nonconscious Mimicry

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

Summary

This study on unilateral neglect found that visual feedback improved drawing performance in a patient with right hemisphere damage. This suggests spatial working memory deficits may contribute to neglect symptoms.

Area of Science:

Neuroscience
Cognitive Psychology
Rehabilitation Science

Background:

Unilateral neglect is a cognitive disorder often resulting from right hemisphere damage.
Patients with neglect struggle to attend to or represent stimuli on the contralesional side of space.
The role of visual feedback in compensating for neglect during drawing tasks is not fully understood.

Observation:

A patient with right hemisphere damage and left unilateral neglect was assessed on drawing from memory tasks.
Drawing performance was compared between conditions with and without visual feedback.
Conditions without visual feedback included being blindfolded or using a pen with the cap on.

Findings:

The patient exhibited significantly more neglect during drawing tasks performed without visual feedback compared to those with visual feedback.
This finding contrasts with some previous research on unilateral neglect.
The results suggest that visual feedback may aid in compensating for neglect.

Implications:

The findings suggest that spatial working memory deficits may play a role in this patient's pattern of neglect.
Visual feedback may be a valuable tool in cognitive rehabilitation for unilateral neglect.
Further research is needed to explore the mechanisms by which visual feedback aids neglect compensation.
