Test 2 Flashcards
What are the two views of the brain/mind distinction?
- Physiological approach
2. Cognitive Approach
Explain the physiological approach to the brain/mind distinction.
The brain and the mind are the same thing; everything is just a chemical reaction
Explain the cognitive approach to the brain/mind distinction
The physical brain and our mind are separate; the mind is in the brain, but is not the same thing
Explain The Physiological Approach
-We are born with a brain that is programmed to perform certain functions to ensure our survival.
When related to the physiological approach responses…
- Responses are automatic; we do not have to learn them
- Responses can be measure physically
The physiological approach for the study of media effect…
Give us insights into how all humans are the same; how the media affect our basic human programming.
The Brain vs. The Media
- The brain is old, it has developed over millions of years
- Media are new, are only a few hundred years old
The results of The Brain vs. The Media
- Brains has not had enough time to adapt to new stimuli of media
- Media are interpreted by our brain as real-world stimuli
Automatic Processes
- Hard-wired into our brain
- Run automatically with no need for us to think about them ex. breathing & heart beating
Quasi-atuomatic Processes
- Psychophysiological –> cognitive
- goal is to move from limbic system to cortical part of brain. -ex. fight or flight
What are the four types of physiological processes?
- Perceptual processes
- Automatic survival mechanisms
- Sexual mechanisms
- Neurophysiological responses
Explain the perceptual process
help us orient to our environments by selecting certain types of stimuli to attend to.
Explain Automatic survival mechanisms
Body readies itself to fight or escape a threat
Explain sexual mechanisms
Driven by the biological need to reproduce
Neurophysiological responses
Complex set of chemical and electrical processes that media can influence
Name four ways in which one can measure physiological responses
- Brain waves
- Skin conductance
- Heart rate
- Facial EMG
Explain EEG
- Measures: brain wave activity
- Assesses: Relaxation, focus
Explain GSR
- Skin Conductance
- Measures: Electricity conducted between fingers
- Assesses: Arousal, excitation, interest
Explain ECG/EKG
- Measures: Heart rate, beats per minute
- Assesses: Orienting response & attention
Explain EMG
- Measures: Electrical potential generated by muscles (ex. eyebrows)
- Assesses: Emotions (e.g., frustration, surprise)
Most media effects research has focused on…
Triggering function
What are the two triggering effects?
- Orienting reflex
2. Arousal
Explain orienting reflex
- Our brains continually monitor all incoming information
- When something changes, the orienting reflex causes us to pay attention to it
The orienting reflex is accompanied by:
- Decrease in muscle activity
- Lower heart rate
- Shorter, faster breathing
Triggering physiological effects: What are the four types of arousal?
- Generalized Brain Arousal
- Fight/flight reflex
- Sexual arousal
- Excitation Transfer
Explain Generalized Brain Arousal
Orienting reflex energizes brain and stimulates brain activity, which makes attention possible.
How do we know the brain is aroused?
MRI scans
Examples of physiological media effects:
- Fast-paced media stories increase skin conductance
- Exciting content increases heart rate
Explain Fight/Flight Reflex
- We experience vicarious response to character’s fight/flight
- Triggers our attention and our own fight/flight reflex
Explain Sexual arousal in media
-Erotic material presented in media messages triggers sexual arousal, this response is automatic
Excitation Transfer
- Arousal from one activity transfers to another
- Can’t distinguish remaining excitement from new excitement
What are the two altering effects:
- Habituation
2. Altering brain waves
Explain Habituation
When the media present the same pattern of stimuli over and over again, they lose their power to elicit the same degree of reflex over time
Example of Habituation
Desensitization to violent media
Can habituation be positive
Yes
Alpha Blocking:
Beta waves block alpha waves when paying attention to something
What are the four reinforcing physiological effects
- Orienting reflex
- Passivity
- Arousal
- Narcotization
Explain orienting reflex and arousal
- Orienting to stimuli leads to pleasure
- So we orient and are aroused again and again
Explain passivity
- Consuming media passively, rather than actively
- Reading is more active in contrast to watching tv
Explain Narcotization
- Long-term build-up of orienting –> arousal
- Become dependent on media and keep seeking more of it
The Cognitive Approach
Human thinking is governed by the mind, which is located in the brain but is not the same thing as the physical brain
The cognitive approach and media effects
Gives us insights into the many differences that exist across the array of humanity
What are the nature of cognitive effects
- Social Learning
- Instructional
- Education
What are the types of the cognitive processes
- Inferring patterns
2. Generalizing Patterns
Explain Inferring patterns
Building an idea about someone/something by repeated media exposure
Explain Generalizing patterns
New information alters an existing pattern and the pattern becomes more stable
Acquiring Effects
We acquire a lot of information through media
Acquiring effects about the real world
- Current events
- Political candidates
- Brand/product advertisements
- Science
Acquiring effects about the media world
- Fictional narratives and characters
- TV production
