Exam 2: Study Notes on the Effects of Violent Media on Aggression

Day 6: Exposure to Violent Media

Overview of the Study

  • The primary focus is on the effects of songs with violent lyrics on aggressive thoughts and feelings.
  • Critique raised about two major methodological issues:
    1. Claim of Fundamental Change
    • Challenge to the assertion that exposure to a single piece of media can fundamentally change an individual's behavior.
    • Lack of baseline data regarding participants' previous exposure to specific genres of music, which is critical for assessing changes.
    1. Weak Manipulation
    • In experimental studies, the manipulation should effectively induce the intended changes.
    • Question raised about whether listening to a single song could plausibly evoke hostility.
    • Example selected, Tool's song with only one aggressive line, deemed inadequate.
  • Conclusion on the choice of music genre: a more aggressive song could have been selected for better results.

Experiment 1

Procedure and Design
  • Independent Variable (IV): Song by Tool:
    • Violent ("jerk-off") versus Non-violent (four degrees).
    • Lyrics are interpreted differently although the songs are similar in nature.
  • Dependent Variables (DV):
    • State Hostility Scale: Measures immediate feelings of hostility (e.g., "At this moment, I feel hostile").
    • Trait Hostility: Assessment of regular hostility levels.
Results
  • The violent song produced a higher state of hostility, with a notable increase especially in females.
  • Criticism: No baseline measure was taken to assess pre-existing hostility levels.

Experiment 2

Procedure and Design
  • Similar to Experiment 1, but focused on:
    • New Dependent Variable: Aggressive Cognition, defined as the tendency to think aggressively.
    • Utilized a validated measure against trait hostility.
  • The hypothesis posited that individuals with higher trait hostility would perceive similarities in words more readily than those with lower scores.
Critique
  • 190 Instruments: Questioned the reliability as the measure derived from earlier research with potential biases.
  • Noted that all words in the inventory are ambiguous, affecting clarity of results.
Objective Words Used
  • 1. Alley
  • 2. Animal
  • 3. Bottle
  • 4. Red
  • 5. Movie
Aggressive Words Used
  • 1. Blood
  • 2. Butcher
  • 3. Choke
  • 4. Fight
  • 5. Gun
  • 6. Hatchet
  • 7. Hurt

Experiment 3

Procedure and Design
  • Expanded to include comparisons between four violent and four non-violent songs.
    • Example of collaborative music: Run DMC (rap) with Aerosmith.
Findings
  • Overall findings indicated a state-hostility effect based on violent lyrics, but other external activities disrupted this effect.
    • It was proposed that trait hostility accounted for the observed effect; individuals already inclined to hostility remained so after listening to the songs.
Statistical Analysis
  • Main analysis indicated that the violent song effect was in the predicted direction but was not statistically significant ($.16$).
  • Re-analysis of state hostility scores also indicated a lack of statistical correlation.
  • It was observed that aggressive words were more easily recalled.

Experiment 4

Procedure and Design
  • Introduction of humorous yet violent songs:
    • Conditions included violent songs presented in a humorous context (e.g., Jonny Cash versus Allan Sherman, and a comparison with a control group with no song).
Example Used
  • "A Boy Named Sue": Narrative involving a child confronting violence from his father (written by Shel Silverstein).
  • Humorous content versus violent context was analyzed.
Key Findings
  • The humorous aspect effectively canceled out the effects of violence.
  • Potential indication of inappropriate attempts at p-hacking noted; suggesting marginal differences presented as statistically nonsignificant should not be interpreted as conclusive evidence.

Experiment 5

Procedure and Design
  • Addressed both independent variables: humor and violence, with a control group (no song).
  • Used songs by Weird Al Yankovic as humorous and songs by Violent Femmes as non-humorous.
Findings
  • Both dependent variables: state hostility and aggressive cognition measured.
  • Results showed that humor did not eliminate the effects of violence.
  • Reported findings were once again statistically non-significant (.09).

General Conclusions

  • The findings indicated a consistent increase in state hostility and aggression, although authors acknowledged that data did not definitively support a causative effect from violent lyrics.
  • Speculation raised on the potential for long-term effects of exposure to violent songs, although acknowledged as a short-term priming effect in this study.
  • Conclusion: Individuals already predisposed to hostility might experience increased hostility after exposure to violent songs, while others may show a slight increase in hostility with a noted small difference.
  • Strong recommendation for obtaining baseline data to support conclusions in future studies.
  • Summary point: The manipulation employed in the experiments was deemed weak, undermining the claims made by the researchers.
