Guitar Research & Evidence-Based Practice 5

Question 1

A researcher uses 'purposive sampling' to recruit guitarists for a study on professional stage fright. This means participants were selected because:

Accepted Answer

They possess specific characteristics relevant to the research question

Answer

Purposive sampling deliberately selects participants who have the characteristics, experiences, or knowledge most relevant to the study's purpose.

Question 2

Which of the following practice strategies has the STRONGEST empirical support for skill retention in motor learning research applicable to guitar?

Accepted Answer

Distributed practice (shorter, more frequent sessions)

Answer

Distributed (spaced) practice has robust empirical support for long-term retention compared to massed practice, a finding well-established in motor learning research.

Question 3

An IRB (Institutional Review Board) review is required before conducting research involving human participants primarily to:

Accepted Answer

Protect participants' rights, welfare, and confidentiality

Answer

IRBs exist to safeguard human research participants by reviewing studies for ethical standards, informed consent procedures, and risk minimization.

Question 4

In a guitar performance study, researchers find r = 0.85 between hours of deliberate practice and sight-reading scores. What does this correlation indicate?

Accepted Answer

There is a strong positive association between practice hours and sight-reading scores

Answer

A correlation of r = 0.85 indicates a strong positive relationship, but correlation alone does not establish causation.

Question 5

Which term describes a guitar teacher's willingness to change instructional methods when credible new research contradicts traditional approaches?

Accepted Answer

Reflective practice and evidence responsiveness

Answer

Reflective practice involves critically evaluating one's methods against evidence and adjusting accordingly, a core competency in evidence-based teaching.
