Psych 290 - Exam 1 Prep

Researchers recruited parents of infants who lived in urban settings and in rural settings. Parents were asked to rate their infant's disposition on a scale from 1 (very fussy) to 10 (very happy). Rural infants were rated as more fussy than urban infants. (inspired by 10.1002/jcop.22313)

What type of study is this?

• Non-Experimental

• Experimental

Researchers recruited parents of infants who lived in urban settings and in rural settings. Parents were asked to rate their infant's disposition on a scale from 1 (very fussy) to 10 (very happy). Rural infants were rated as more fussy than urban infants.

How is disposition measured?

• Self-report

• Naturalistic observation

• Performance based

• None of these

Researchers recruited parents of infants who lived in urban settings and in rural settings. Parents were asked to rate their infant's disposition on a scale from 1 (very fussy) to 10 (very happy). Rural infants were rated as more fussy than urban infants.

How precise is the measure of disposition?

• Nominal

• Ordinal

• Interval

• Ratio

How precise is the measure of setting/environment?

• Nominal

• Ordinal

• Interval

• Ratio

...Rural infants were rated as more fussy than urban infants.

Parents might rate their children as more happy than they really are.

This is a worry over...

• Reliability

• Validity

• Alternative explanation / confound

• External validity / generalizability

...Rural infants were rated as more fussy than urban infants.

Researchers also made video recordings of each infant and scored their disposition for how often they smiled. They found good agreement with the parent ratings.

What standard of science is being addressed?

• Test/Retest Reliability

• Inter-rater Reliability

• Inter-item or Internal Reliability

• Convergent Validity

• Criterion Validity (Predictive or Concurrent)

Researchers showed participants upsetting images and asked them to talk through their emotions. Some participants were instructed to speak in the first person ("I feel upset and sad") and others in the third person ("Jose is upset and sad"). An EEG was used to measure the number of stress-related brain events that occurred. Researchers found those who spoke in the third person had fewer stress-related brain events.
