Media Effects Research
2
The Early Years
  • The history of media research begins in the
    period leading up to WWII when radio was
    beginning to make an impact on the cultural
    world.
  • Two important early works
  • Cantril and Allport, 1935, The Psychology of
    Radio
  • Cantril, Gaudet, and Herzog, 1940, The Invasion
    From Mars A study in the Psychology of Panic.

3
The Early Years
  • Early media effects theory The Hypodermic Needle
  • Term coined by Lasswell, 1935
  • The injection of ideological bias that
    contaminated radio listeners in the manner of
    brainwashing.

4
The Early Years
  • Much of the academic literature about media in
    the early days of radio and television had a
    strong negative flavor.
  • Two biggest influences on media theory
  • North American sociology
  • The Frankfurt School

5
Critics of Early Approaches
  • The overly negative hypodermic needle approach
    to mass media received much criticism.
  • The critical theories (predominantly European)
  • Marshall McLuhan
  • Challenged the view that media is inherently
    dangerous.
  • the medium is the message
  • global village
  • Postmodernism a historical period a
    theoretical position.
  • Refers to a a break with tradition characterized
    by the collapse of the traditional values.
  • Media can bring different cultures together,
  • Breaking away from the high culture may not be
    a bad thing.

6
Critics of Early Approaches
  • The empirical science
  • Postmodern theories had little impact in the
    North America
  • However, the scientists have incorporated some
    core concerns from the critical theories into
    their research.
  • Critical theorists, on the other hand, largely
    ignored and discredited scientific methods.
  • This is where modern approaches to media started
    to diverge from each other.

7
Critics of Early Approaches
  • The limited effects paradigm
  • Some media content may influence some people some
    of the time under some circumstances.
  • The effects of media are often indirect

8
The Effects Tradition
  • The media effects tradition has probably had
    the greatest impact of all media research on
    public.
  • Concerns of the psychological effects of media
    are so common that they are rarely questioned
    outside of academia, except for the industry
    itself.

9
The Effects Tradition
  • In the broadest sense, media effects research
    explores the social, psychological and behavioral
    consequences of media exposure, particularly
    those consequences that are negative.

10
The Effects Tradition
  • The key question to ask is
  • WHO sends WHAT message to WHOM, WHEN, in WHAT
    WAYS, and with WHAT EFFECT?

11
The Effects Tradition
  • Media effects research can be organized across a
    five basic dimensions
  • content
  • timing
  • type
  • direct versus indirect effects
  • explanatory mechanisms

12
Content
  • Media effects are the result of exposure to
    different media content. Media effects scholars
    often study, for example, the impact of
    advertising, news, as well as many other forms of
    entertainment programming.
  • Two of the most frequently studied types of media
    content in the effects tradition are portrayals
    of violence and sex

13
Timing
  • Media effects can occur either immediately or
    long time after exposure. Some effects of media
    exposure may last only for a few minutes (e.g.,
    physiological arousal) whereas others may last
    for a long time, even for a lifetime (e.g.,
    attitudes and beliefs about the world). Other
    effects are perpetuated across time through
    repeated exposure to the media.

14
Types of Effects
  • Most research about negative media effects focus
    on individuals physiological, cognitive,
    emotional, attitudinal, and behavioral changes
    through media exposure.
  • e.g., arousal, fear, happiness, learning, etc.

15
Direct/Indirect Effects
  • Media effects can happen directly as a result of
    an individuals exposure to media content
    unmitigated or mediated by other people or
    processes. Or, individuals can be affected by
    media indirectly through changes in ones social
    environment, the presence of other people or a
    variety of other contextual features of the media
    consumption situation.

16
Explanatory Mechanisms
  • WHY do certain effects happen? Through what
    process do they happen? How? This is the most
    important and interesting question to ask.
  • e.g, media effects happens through physiological
    arousal. The nervous system reacts to media input
    and causing viewer to think or act in certain
    ways.
  • Media effects happens through cognitive process.
    People think about the incoming message
    understand it and then affected by it.
  • A mix of the two
  • Other factors include personality, context of
    viewing, etc.

17
Methods of Media Effects Research
  • Almost exclusively quantitative, especially
    experimental.
  • Cares about the causal relationship (the word
    effects should give this away).
  • Stemmed firmly in the experimental psychology
    tradition.

18
Theories of Media Violence (an example of media
effects research
  • Theories are not truths.
  • They are intelligent speculations supported by
    empirical evidence.
  • Some theory received more support empirically
    than others.
  • However, intuitive theories often have more
    believers regardless of actual evidence.

19
Theories of Media Violence
  • Functions of theories
  • Description
  • Prediction (practical for social research)
  • Explanation (the ultimate goal of science)

20
Theories of Media Violence
  • Explanatory mechanisms the whys
  • Biological
  • Cognitive
  • Psychological
  • Social
  • Comprehensive (multiple perspectives)

21
Theories of Media Violence
  • Human behavior is influenced by many factors
  • Internal vs. Environmental
  • Nature vs. Nurture

22
A Biological Perspective
  • Fear and aggression are two of the primary
    survival tools for human.
  • We either flight (fear) or fight (aggression)
    when facing a threat from the environment.

23
A Biological Perspective
  • Media violence triggers biological
    (physiological) changes, specifically a general
    arousal, similar to how people respond to a real
    life threat (flight or fight).

24
A Biological Perspective
  • Our assessment or appraisal of this arousal may
    have two outcomes
  • Fear the situation is threatening
  • Excitement the situation is challenging
  • Fear ? discomfort, anxiety, and possibly
    emotional harm
  • Excitement ? aggression

25
A Biological Perspective
Fear
Flight
Exposure to Media Violence
General Arousal
Fight
Challenge
26
A Biological Perspective
  • Excitation Transfer Theory (Dolf Zillmann)
  • Violent Media ? general arousal.
  • Physiological arousal leaves residual excitation.
  • This excitation is being transferred to the
    subsequent real life event.
  • This leads to aggression in real life.

27
A Cognitive Perspective
  • Human consciousness and self-control is powerful
    enough so that mere physiological arousal may not
    be enough to cause real life aggressive behavior.
  • Thus, the impact of media violence is ore
    cognitive than biological.
  • How do we cognitive process media messages is the
    key here.

28
A Cognitive Perspective
  • Recall an earlier lecture on the cognitive
    perspective
  • Associationistic cognitive structure
  • Schematic cognitive structure

29
A Cognitive Perspective
Acceptance of violence
Exposure to Media Violence
Cognitive Processes
Real life violence
Learning of violence
Existing knowledge memory structure
Familiarity with violence
30
A Cognitive Perspective
  • Priming Theory
  • Media primes or activates violent nodes (e.g.,
    gun, killing, murder) in the associative memory
    network.
  • The activation of these nodes in turn activates
    other linked nodes in this network through the
    process of spreading activation.
  • This process leads to an increase in the
    accessibility (familiarity) of violent thoughts.
  • When facing threats or challenges in real life
    (e.g., a guy pushed in a crowed subway) we are
    more likely to access violent thoughts in our
    cognitive network.
  • This leads to real life violence.

31
A Psychological Perspective
  • There are a number of psychological factors that
    are not included by the biological and cognitive
    perspectives.
  • But they are equally powerful sources of
    influence

32
A Psychological Perspective
  • A psychological perspective emphasizes on the
    importance of individual differences.
  • Gender
  • Motivation
  • Personality
  • Cognitive ability
  • Self-awareness
  • Self-esteem
  • And many more

33
A Psychological Perspective
  • The Confluence Model of Aggression (Neil
    Malamuth)
  • Media impact is considered only within the
    confluence of other psychological factors
    relevant to a particular behavior.
  • In other words, we should not worry about
    everyone being influenced by mass media. We
    should focuses on those people who are more
    easily influence due to certain psychological
    pre-dispositions.
  • e.g., HEAVY PORNOGRAPHY USE PREDICT GREATER
    SEXUAL AGGRESSION ONLY FOR MEN HIGH IN RISK FOR
    SEXUAL AGGRESSION.

34
A Social Perspective
  • We are not isolated beings. We live in a social
    world.
  • Biology and psychology are not enough to make us
    behave in certain ways.
  • We have to consider the social factors.

35
A Social Perspective
  • Media can influence society
  • Violence as a social norm (e.g., war coverage on
    TV, high amount of violence on TV, etc).
  • It enhances a heroic cowboy culture
  • It changes our social perception
  • But media is only one of the social factors that
    may contribute to real life violence.

36
A Social Perspective
  • Our Society also has a number of pre-dispositions
  • Availability of guns in the society
  • High level of stress among citizens (e.g., long
    working hours)
  • Individualism
  • Education
  • Poverty

37
A Comprehensive Perspective
  • A good theory must be empirically testable.
  • Thus a good theory is usually narrow and with
    constrains.
  • Thus one theory can never explain everything.
  • Thus recent efforts in media violence research is
    to synthesize different theories.

38
A Comprehensive Perspective
Social factors
Cognitive factors
Attitude emotion behavior
Psychological factors
Biological factors
Media violence
39
A Comprehensive Perspective
  • A good idea but
  • Lack of specification
  • Impossible to be empirically tested
  • The relations are way to complex to be meaningful
  • The most accurate map of the world is the world
    itself, but it will be a useless map in terms of
    its function.

40
A Comprehensive Perspective
  • A good synthesis of theories must
  • Include only those theories that are well-tested.
  • Be logical and not have internal contradictions.
  • Limit only to relevant factors and variables.
  • Empirically testable.

41
A Comprehensive Perspective
  • Some examples of good comprehensive theories
  • Social Cognitive Theory (Banduras own revisions
    of the social learning theory) a cognitive
    theory that considers several psychological and
    social factors.
  • General Affective Aggression Model (Craig
    Anderson) has both emotional and cognitive
    components, and accounts for long term and short
    term effects.
