PSYCH 530 1st Edition Lecture 3 Outline of Last Lecture Outline of Current Lecture II. Experimental MethodA. True experimentsIII.Liebert and BaronIV. Josephson, 1987V. Albert Bandura’s theory of social learningCurrent Lecture- Advertisers spend billions of dollars due to the belief that T.V. can influence human behavior.- T.V. industry enthusiastically agrees, but nonetheless contends that its programs of violence do not have any such influence- Average American household has T.V. on for 7 hours/dayo 58% of T.V. shows contain violenceo Average cartoon shows a violent act every 3 minuteso Infants (<1 years old) are exposed to 1 hour/dayo Children watch 2-4 hours/day- Children at the age of 12 have seen 100,000 acts of violence (including 8,000 murders)- Longitudinal study: a study that follows one person for a long period of timeo Survey studies using longitudinal designs measure the viewing of violent T.V. programs inchildhood or adolescence and aggressive behaviors later in life.o Studies show positive correlations between exposure to violence and aggressive behavior (violent acts, assault, etc.); effect is even stronger with time.- Reverse causality is possible; aggressive kids may be more likely to watch violent T.V. the aggressiveness of a child causes them to choose violent T.V. programs- Third Variable: another explanation for why the results that were obtained were obtainedo Parents who neglect their kids may be responsible for aggressive behaviors, for leaving the T.V. set on all the time, or maybe the child lives in a violent neighborhoodThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute. It may not be the violent T.V. program at all- 700 families over 17 years were studied to observe long-term effects of exposure to violent T.V. o Positive correlation between exposure to violent and aggressive behavior Regardless of parental education, family income, and neighborhood violence.o Still a third variable could be genetics! A BViolent T.V.  AggressionCompetitive Race Faster CyclingStorks (birds) More babiesA BA B (reverse causality)Example: People believe that with more storks, more babies were born. However, in reality, more storks came because they liked roosting in houses and people were building larger houses because they were having more babies.Experimental Method: 1. Create laboratory simulation of real life processes2. Vary, or manipulate, one or two features of the situation; this is the Independent Variable (IV)a. IV is hypothesized to influence the outcome, or Dependent Variable (DV)b. We manipulate the IV and measure the DVTrue Experiment: 2 requirements:1. Experimental control: hold all other variables constant while manipulating the IV2. Random assignment to condition: participants are assigned to experimental conditions on a random basis—each participant has an equally likely chance of being in either condition.*if both requirements are met, we are able to make a causal inferenceChildren Reeling Fishing RodsAlone CompetitionXXXXXXXXX- If children reel fishing rods faster after meeting these requirements, it was BECAUSE OF competition causal inferenceViolent T.V. on Aggression Study5 years of Violent T.V. 5 years of Non-Violent T.V.XXXXXXXXX- We can’t always get control over the thing we want to study.o Parents won’t hand over their children to us for 5 years- However, if we were we able to implement control over the 5 year duration and there was more aggression, we could conclude that it was BECAUSE OF violent T.V. causal inferenceLiebert & Baron Study- 136 kids came in for a study- They watched T.V. in a waiting roomo They saw either “The Untouchables” (2 fistfights, 2 shootings, and 1 knifing) or an exitingtrack meet- After waiting one of the two programs, they were allowed to pay with toys (e.g. slinky, space station, guns)- Later, they were went into the experiment and played another game with other children1. Arrange conditions to isolate effect of IV (violent of program)a. Standardize conditions and assign participants randomly2. Vary only the IV:a. Experimental group: Violent filmb. Control group: Non-violent film3. Measure DV4. Compare 2 groupsExperimental Group (violent film) Control Group (non-violent film)More aggression-played with violent toys-more hostile in gamesJosephson, 1987- Violent T.V. programming (vs. bicycle race) and floor hockey games- Kids who were rated more aggressive by teachers showed the biggest effects—much more aggression in hockey game after violent T.V. show- “One-shot” studies don’t produce aggression in everyoneDo lab studies get at what we really want to know?- Can we generalize?- Can we build up to causal studies?o 5 year studies (filed studies) are needed, but they are extremely hard to doWhy does media violence affect viewers?1. “If they can do it, so can I” (weakens inhibition)2. “Oh, that’s how you do it!” (learning, modeling)3. “I think I’m feeling aggressive” (priming aggressive thoughts)4. “Ho hum…another brutal killing” (numbing effects of violence)5. “I better get him before he gets me” (media violence affects our view of the world)Albert Bandura’s theory of social learning- We learn social behavior (e.g. aggression) by observing other and imitating themo Bobo doll (inflated doll) experiment Teacher walks into room and pummels (with mallet), kicks, beat, and flung the Bobo doll and the kids imitate what they learn by watchingo Children who didn’t see violence never exhibited
