Document Summary
Children are observed as they behave spontaneously in real-life situations (pg 24), and record behaviour. Often involves going into homes, schools or playgrounds. Strengths: easy to use with infants and toddlers who cannot give a verbal. Findings are more likely to reflect (cid:494)natural(cid:495) behaviour (cid:523)i. e. high on ecological. Weaknesses: some behaviours are so infrequent (and/or undesirable) that response validity) they are not likely to be observed. Many things happening at once so hard to pinpoint cause of observed behaviour. The researcher creates a setting likely to elicit the behavior of interest (pg. Ex: create a task where the grammatical errors under interest are more likely to occur (try to increase frequency of that behaviour) Strengths: easy to use with infants and toddlers who cannot give a verbal response. Can be used to study behaviours that are rare or typically occur in private settings. Weaknesses: maybe invalid if the structured setting distorts the behaviour.
