Lobes Flashcards
(30 cards)
What is the Cerebral Cortex?
Wrinkled part of the brain; controls mental processes such as thought.
The cerebral cortex is integral for higher-level functions in humans.
How many lobes does the Cerebral Cortex have?
4 lobes
The four lobes are frontal, parietal, occipital, and temporal.
What is the main function of the Frontal Lobe?
Movement & thinking
The frontal lobe is crucial for executive functions and voluntary motor control.
What does the Parietal Lobe control?
Touch sensation & spatial relationships
It processes sensory information from the body.
What is the primary function of the Occipital Lobe?
Visual cortex
It is responsible for processing visual information.
What does the Temporal Lobe process?
Sounds, including speech
It plays a key role in auditory perception and memory.
What is the Motor Cortex?
An area behind the frontal lobes that controls movement.
It is responsible for the planning, control, and execution of voluntary movements.
What is the function of the Sensory Cortex?
Receives info from skin senses & from the movement of body parts.
It integrates sensory input for processing.
What are Association Areas involved in?
Higher mental functions: learning, remembering, thinking & speaking
These areas connect different types of information for complex cognitive tasks.
What is Broca’s area responsible for?
Producing language
It is located in the left hemisphere of the brain.
Define Broca’s Aphasia
Understand language, hard to find words; aware of their problems
This condition affects speech production but comprehension remains intact.
What is Wernicke’s area responsible for?
Speech comprehension
It is crucial for understanding spoken language.
Define Wernicke’s Aphasia
Difficulty understanding speech; speech is intelligible but uses nonsense words; unaware of their disability
This condition results from damage to Wernicke’s area, impacting comprehension.
What is the Corpus Callosum?
The structure that connects the two hemispheres of the brain.
It facilitates communication between the left and right hemispheres.
True or False: The brain is protected by the skull and three membranes called meninges.
True
These protective layers also include cerebrospinal fluid that acts as a shock absorber.
What is the condition called when there is too much fluid in the brain?
Hydrocephalus
This condition can lead to increased intracranial pressure.
What is reaction time (RT)?
RT is related to brain hemispheres and involves processing speed and response execution
RT is influenced by task type, motor control, and inter-hemispheric communication.
How does reaction time influence cognitive psychology?
It provides insight into mental processes, such as decision-making, attention, and memory
Psychologists use RT to study how quickly individuals perceive, process, and respond to stimuli.
What are the effects of stimulus complexity on reaction time?
It impacts processing speed
Complexity can either slow down or speed up RT depending on the nature of the stimulus.
How do attention and distraction affect reaction time?
Divided attention or distractions can increase response time
This indicates the importance of focused attention in cognitive processing.
What impact does cognitive aging have on reaction time?
Cognitive abilities, including reaction time, change with age
Older adults may experience slower reaction times compared to younger individuals.
What role do neurological conditions play in reaction time?
They can indicate potential cognitive impairments
Measuring RT helps assess cognitive function in individuals with neurological disorders.
Which hemisphere is associated with faster reaction times for language tasks?
Left Hemisphere
It is dominant in right-handed individuals for language and sequential problem-solving.
What tasks are associated with faster reaction times in the right hemisphere?
Visual-spatial tasks, recognizing faces, and processing emotions
The right hemisphere is key for responding to non-verbal stimuli.
