Fischer

Fischer (2003) CT: Strength

- Method Triangulation (fMRI, semi-structured interviews, and a Likert scale questionnaire) → They used both objective and subjective measures.

- Internal Validity (Control i.e. same time each image was presented)

Fischer (2003) CT: Weakness

- Low Mundane Realism

- Order Effects (repeated measures design - was the brain activation impacted by which image was shown first?)

- Likert Scale (subjective) → Also Low Construct Validity

Fisher (2003) Research Method

True (lab) Experiment
Repeated Measures
IV: Neutral Object vs Loved Person
DV: Dopamine levels and areas of the brain activated.
