scientific method
The process scientists use to guide their research
- Ask a question
- create a hypothesis that might answer the question
- design and conduct an experiment
- record result/data
- analyze and conclude
- report
correlation
correlation: relationship between two or more variables
- positive: variables change in same direction
- negative: variables change in different directions
research design groups
groups:
- experimental
- control
neurons
Cells in the brains that allow electrical signals to pass.
Comprises a
soma, the main body,
dendrites, little root-things that connect with the axon of other neurons,
And an axon where electrical signals pass to other neurons at the synapse
neurotransmitters and what they do
Neurotransmitter: a chemical messenger of the nervous system
Sleep deprivation (debt and rebound)
Sleep debt – result of insufficient sleep on a chronic basis.
Sleep rebound – a sleep-deprived individual will tend to take a shorter time to fall asleep during subsequent opportunities for sleep.
Why we sleep
Adaptive Function (Evolutionary Hypotheses)
- Sleep is essential to restore resources, and is an adaptive response to predatory risks, which increase in darkness (not much evidence for this).
Cognitive Function
- Sleep is important for cognitive function/memory; increased sleep deprevation = decreased memory
Benefits of sleep
- Maintaining a healthy weight, lowering stress levels, improving mood, increased motor coordination as well as many benefits related to cognition and memory formation.
Atkinson Shiffrin model
sensory input > sensory memory > STM > LTM
- Sensory memory – storage of brief sensory events, such as sights, sounds, and tastes.
- Short-term memory/working memory – a temporary storage system that processes incoming sensory memory.
- Long-term memory - the continuous storage of information
Types of Long-term memory
Explicit (declarative) memory – memories of facts and events we can consciously remember and recall/declare.
Implicit memory - memories that are not part of our consciousness, formed through behaviors unknowingly.
Cerebral Cortex
brainfacts.org/3d-brain
- outer top layer of brain
- split between left/right hemisphere
-contains frontal, temporal, parietal, and occipital lobes
- connected by corpus callosum
Thalamus
- located in center of brain
- relays sensory information
Limbic System
Involved in memory and emotion
- Amygdala: manages emotion memory and fear
- Hippocampus: associated with learning and memory
- Hypothalamus: regulates homeostatic processes
Hindbrain
Area in back of brain
- Medulla: controls automated processes: breathing, bld. pres., hrt. rt.
- Pons: connects brain and spinal cord, involved in activity during sleep
- Cerebellum: balance, coordination, movement, motor skills
eyewitness testimony reliability
Unreliable, people are suggestible and aren’t focusing on specific details in time of fight or flight
