Chapter 5 - Consciousness Flashcards
Two messages being said at the same time example an iPod playing two different things in each ear
Dichotic listening
The process of seeking out stimuli and focusing on them
Attention
What is consciousness?
Subjective awareness of internal and external stimuli (how mentally alert you are)
What is the cocktail party effect?
A shift in your attention when you hear something personal like your name.
What is change blindness?
Failure to detect changes in a scene when there is a brief visual disruption. Occurs when people are told to look for a change In a movie between scenes, the bloopers
Your inability to notice a new event (B) while attending to another event (A)
Unintentional blindness
Ex. The submarine commander who was looking for only enemy ships and crashed into an ally ship
What is Dual task interference?
Stroop task, your ability to form one task interferes with your ability to complete another task
Ex. Word is blue but the colour is black
Hemineglect
Ignoring one side of everything
What scans brain waves?
Electroencephalogram
Gives info about muscle tone
Electromyogram
What is the purpose of beta waves?
You are alert, 13-30Hz (high frequency) small amplitude
What is the desynchronization pattern?
When your neurons are working independently ex. A choir are all singing different pitches
Responsibilities of alpha waves
Relaxed on eyes closed
8-12 Hz (medium frequency) bigger amplitude
Pattern is more synchronized ex. Choir has soprano alto tenor bass
What is nominal fallacy?
Naming something with explaining it
What are the 4 stages of sleep?
Stage 1: theta activity (3.5-7.5 Hz, lasts about 10 minutes)
Stage 2: theta activity, sleep spindles (12-14 Hz, lasts about 15 minutes) the k complexes drown out external environment so we stay asleep
Stages 3 & 4: (slow wave sleep) delta waves. (Large in amplitude low in frequency, 3.5 Hz)
