Behavioral Science Flashcards
conformity
the changing of beliefs or behaviors in order to fit into a group or society.
Locus of control
The characterization of the source of influences on the events in one’s life; can be internal or external.
Explicit Memory
Memory that requires conscious recall, divided into facts (semantic memory) and experiences (episodic memory); also known as declarative memory.
Hypothalamus
Key player for emotional experience during high-arousal states, aggressive behavior, and sexual behavior.
- controls endocrine functions as well as autonomic nervous system
- plays in homeostasis
- receptors regulate metabolism, temperature and water balance
Thalamus
Important relay station for incoming sensory information, including all senses except for smell. Projects incoming signals to appropriate areas in the cerebral cortex
Cerebral cortex
outer covering of the cerebral hemispheres
-divided into four lobes
Frontal lobe
executive function, impulse control, long term planning, motor function, speech production (Broca’s area)
Parietal lobe
sensation of touch, pressure, temperature, and pain (somatosensory cortex); spatial processing, orientation, and manipulation
Occipital lobe
visual processing
Temporal lobe
Sound processing (auditory cortex), speech perception (Wernicke’’s area), memory and emotion (limbic sys)
Basal ganglia
coordinate muscle movements as they receive information from the cortex and relay this information to the brain and the spinal cord.
-smoothen movements and help maintain postural stability
Limbic system
comprises a group of interconnected structures looping around the central portion of the brain and is primarily associated with emotion and memory. (includes the amygdala and hippocampus)
Septal nuclei
involved with feelings of pleasure, pleasure-seeking behavior, and addiction
Amygdala
controls fear and aggression
Hippocampus
consolidates memories and communicates with other parts of the limbic system through an extension called the fornix
optic nerve
carries all the information from the associated eye
optic chiasm
contains crossing nasal fibers (the temporal visual field) from each eye
optic tract
carries all the information from the opposite visual field
-project directly to their respective occipital lobe.
Therefore, damage to the right occipital lobe will cause loss of the left visual field.
Also, a complete lesion of the right optic tract would therefore cause a loss of the left visual field from both eyes
nasal fibers
carry information from the temporal visual field
-cross at the optic chiasm
elaborative rehearsal
the association of information in short-term memory to information already stored in longterm memory; aids in long-term storage.
Melatonin
A serotonin derivative secreted by the pineal gland that is associated with sleepiness
Forebrain
A portion of the brain that is associated with complex perceptual, cognitive, and behavioral processes such as emotion and memory.
Social constructionism
a theoretical approach that uncovers the ways in which individuals and groups participate in the formation of their perceived social reality
Accommodation
process by which existing schemata are modified to encompass new information
