Original investigation: participants who prefer low-tempo music will have, on average, a higher heart rate after listening to high tempo music than participants who prefer high tempo music.
sample
Size
- 77 Stage 1 psychology students
- Glenunga International High School, Adelaide
- Participants of similar socioeconomic status
-
Limitations
- Psychology students may have a confirmation bias, they may offer the response they believe are accurate.
- Difficult to generalise the affect of music on arousal to the greater population
- Results are only generalisable to the student population
Strengths:
- Representative of a wide range of ethnicities
- Representative of both genders
Reliability
- The heart rate monitor may have not worked accurately each time.
- some monitors may have worked better than others
-
Validty of music tracks
- some people might've responded better to a different type of high-tempo music
- unrepresentative of high-tempo music
- unable to generalise one song to the whole genre
-
Variables
IV: Music preference
- Subjective qualitative data
-
DV: Heart rate
- Objective quantatative data
- Polar beat heart rate monitor
EV'S:
- Gender, emotional state, music exposure preference, ingestion of substance (caffeine)
- was it music alone? or were participants thinking
-
- Repeated measures; all participants did music segment 1 first
- What the participants were doing before hand which could affect their arousal levels.
-
Ethics
- Informed consent was provided by a consent sheet before the investigation took place, this explained the aim and background of the investigation.
- Voluntary participation was ensured through the consent sheet explaining the aim, the participants were able to leave the investigation at any time.
- Confidentiality was maintained throughout the investigation through the use of anonymous ID numbers to replace names.
