Draganski et al (2004)

Draganski et al: Aim

To see if the human brain structure can change in response to environmental demands

Draganski et al: Participants

26 participants (23 female and 3 male)

Draganski et al: Method

• Juggling group had to learn juggling routine and practice at least a minute a day

• MRI scan done before learning juggling, after mastering routine, and three months without practicing

• Non-juggling group lived normally

Draganski et al: Results

• At 2nd scan, jugglers had more grey matter in areas of brain associated w/ visually detected movement, motor control, and info learning (ex. mid temporal lobe)

• Less gray matter after 3 months but still more than non-juggling group

Draganski et al: Conclusion

• Practicing watching balls move and learning to move in response strengthened the neural connection in brain responsible for activity

• Brain matter associated w/ an activity will decrease if not practicing it

Draganski et al: Strengths

• Clear cause and effect

Draganski et al: Limitations

• Small sample size

• Much of the study took place at home, so uncontrolled

Draganski et al: Connection to Localization of Function

Shows LoF through specific areas of the brain growing

Draganski et al: Connection to BIT

Use of MRI machine showed brain growth

Draganski et al: Connection to Neuroplasticity

• neuroplasticity - brain’s ability to adapt to experience

• Shows neuroplasticity bc participant brains grew when learning new skill
