Summary
Rapid cognitive neurotraining using movement discrimination effectively improved cognitive functions in individuals with Traumatic Brain Injury (TBI). This visual timing exercise offers a new, beneficial approach for mild TBI treatment.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Neurology
Background:
- Traumatic Brain Injury (TBI) affects 3.8 million Americans annually.
- Mild TBI often results in cognitive deficits requiring effective remediation strategies.
- There is a need for rapid brain training exercises to enhance cognitive function post-mild TBI.
Purpose of the Study:
- To determine if cognitive remediation via movement figure-ground discrimination improves vision and cognitive deficits after TBI.
- To investigate a potential paradigm shift in TBI treatment methods.
- To assess the efficacy of movement-discrimination neurotraining.
Main Methods:
- Movement-discrimination neurotraining was employed to address dorsal stream visual timing deficits.
- The study involved four male participants (ages 15-68) with TBI.
- Cognitive skills were evaluated using standardized tests and Magnetoencephalography (MEG) before and after 8-16 weeks of training.
Main Results:
- Movement-discrimination training successfully remediated low-level visual timing deficits and high-level cognitive functions.
- Improvements were observed in selective and sustained attention, reading fluency, processing speed, and working memory for all participants.
- MEG imaging indicated enhanced time-locked activity in the dorsal stream, attention, and executive control networks.
Conclusions:
- Visual movement discrimination training causally improves high-level cognitive functions, including attention, working memory, processing speed, and reading.
- Movement-discrimination training is a rapid and effective method for remediating cognitive deficits.
- This approach offers a novel and highly beneficial treatment for mild TBI.

01:20Traumatic Memory

Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

01:15Causes of Social Behavior II: Cognitive Processes
202
Cognitive processes affect social behavior by guiding how individuals perceive, interpret, and respond to social stimuli. These mental processes enable individuals to assess others' behaviors, attribute causes to their actions, and form expectations based on past experiences.Causes of Behavior and Social JudgmentsIndividuals determine the causes of others' behaviors by distinguishing between personal traits and external circumstances. For example, if a friend frequently arrives late, an...

02:46Uncertainty in Measurement: Reading Instruments

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

01:26Higher Mental Functions of Brain: Learning and Memory
2.1K
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

01:23System of Memory
7.3K
Memory is categorized into three major systems: sensory memory, short-term memory (STM), and long-term memory (LTM). These systems differ in their capacity and the duration for which they can hold information. Sensory memory captures raw sensory input from the environment, holding it for just a few seconds or less. For example, on hearing a brief, loud sound, like a car horn honking, the sound seems to linger in the mind for a moment even after it stops. This is an instance of sensory memory...
