Answer #1

8. The answer is b. reliability. This is because reliability refers to consistency of scores, items of the test, over a period of time. There are two types of reliability – internal and external reliability. Internal reliability assesses the consistency of results across items within a test, and external reliability refers to the extent to which a measure varies from one use to another.

9. The answer is b. attachment. This is because attachment involves a deep and enduring emotional bond, that connects one person to another across time and space. It is characterised by specific behaviors in children, such as seeking proximity to the attachment figure when upset or threatened, and this emotional bond later becomes a mental representation of that person's future intimate relationships. Further, attachment theory explains how the parent-child relationship emerges and influences subsequent development.
