Why do babies have the video deficit? (a term)
Symbolic representation
What is symbolic representation
- can’t tell that something is representing something else -has to develop -don’t know it’s a representation of reality
- scale models -screen study
Correlational designs
- examine relationship btw 2 variables
- both measured as they exist -doesn’t equal causation
Experimental designs
-participants randomly assigned -independent variable is manipulated & dependent variable is measured -everything the same except for the IV
What are some problems with experimental designs?
- lack of generalizability
- ways of measuring dependent variable
- can be time consuming
- ethics
- extraneous variables
Longitudinal designs
- same participants over time
- often w/ correlational
- help further potential causal effect
- direction -which effects which
- can use w/ experimental
Natural experiment
- common in economics
- naturally-occurring circumstances “randomly” creates differences btw individuals
- ex. Notel
What were the results of Notel getting a cable channel?
Children were more aggressive, there were more gender stereotypes -reading scores went down & creative thinking

-change in gender attitudes and fertility -more female autonomy -less children were born
Content analysis
-analyze the content of media -what is being shown/represented -define and identify
Limitations of content analysis?
- doesn’t tell us the effects of content
- difficult to define
- time consuming
Limitations of correlational designs?
- can’t give info on cause & effect
- only 2 variables
- difficulties in operational definitions
- challenges in accuracy of measurements
Limitations of experimental designs?
- expensive
- ethics
- generalizability
- extraneous variables
- how you measure -variability -accuracy
Limitations of longitudinal designs?
- high drop out rates
- very expensive & time consuming
- hard to tell what your effects are due to
- cohort effects (due to context)
Limitations of natural experiments?
- difficult to replicate
- extraneous variables
How do you get around the limitations of studies?
combine
- meta-analysis
- other studies
What do youth consume media?
- Uses and Gratifications perspective
- Self-Determination Theory
