Cognitive Dissonance01:38

Cognitive Dissonance

36.8K
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...

Functional Brain Systems: Limbic System

6.9K
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

Higher Mental Functions of the Brain: Language

3.5K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Traumatic Memory01:20

Traumatic Memory

565
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...

Higher Mental Functions of Brain: Learning and Memory

1.9K
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...

Functional Brain Systems: Reticular Formation01:13

Functional Brain Systems: Reticular Formation

4.6K
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

Area of Science:

  • Neuroscience
  • Psychology
  • Rehabilitation Medicine

Background:

  • Dispositional optimism is linked to health outcomes in various populations.
  • The role of optimism in traumatic brain injury (TBI) recovery is understudied.
  • Cognitive complaints are common after TBI.

Purpose of the Study:

  • To investigate the association between dispositional optimism and cognitive functioning in individuals with TBI.
  • To determine if optimism influences cognitive recovery post-TBI.

Main Methods:

  • 171 participants with TBI completed optimism (LOT-R) and cognitive (BTACT) assessments.
  • Hierarchical regression analysis was used to analyze the data.
  • Optimism was assessed via self-report and structured interview.

Main Results:

  • Optimism was significantly and positively correlated with cognitive functioning after TBI.
  • This association remained significant after controlling for demographic and clinical factors.
  • Higher optimism predicted better cognitive performance post-injury.

Conclusions:

  • Dispositional optimism may enhance cognitive functioning in TBI survivors.
  • Further research should explore optimism-enhancing interventions for TBI cognitive recovery.
  • Optimism could be a key factor in TBI rehabilitation.
