School Readiness Study

The School Readiness Study is a longitudinal study that follows children from 3–7 years of age to better understand how self-regulation and externalizing problems develop, from a bio-psycho-social perspective. In this project, we place special emphasis on the development of neural functioning, as measured by electroencephalography/event-related potentials (EEG/ERP), and how neural development influences the development of children’s self-regulation and externalizing problems. EEG is a method of measuring meaningful differences in children’s self-regulation through ERPs—EEG activity that occurs in response to stimuli—which may be a powerful way of reliably detecting patterns of brain activity that predict behavioral outcomes.

1 Study Glossary

timepoint: each 9-month interval when the target child (TC) comes in for Lab Visit 1 (LV1), Lab Visit 2 (LV2), etc.; 4 time points total per TC (T1–T4)
wave: expected age of target child (TC) in months (36, 45, 54, 63, 72, 81, 90)
cohort: subgroup of participants that reflects the age at which the participant was recruited

Cohort	Age Recruited (months)	TCIDs
1	36	1001–1199
2	45	1201–1399
3	54	1401–1599
4	63	1601–1799

LV1: First lab visit (behavioral tasks, parent–child interaction tasks)
LV2: Second lab visit (EEG)
Target Child (TC): the child participant
TCID: the participant ID of the target child
Primary Caregiver (PC): the parent/caregiver of the target child
Parenting Partner (PP): the Parenting Partner of the child’s Primary Caregiver
Secondary Caregiver (SC): the Secondary Caregiver of the child; could be a teacher, babysitter, nanny, grandparent, other relative, or another caregiver who knows the child well

2 Sample

The sample is a community sample of children and their parent(s)/caregiver(s) in addition to a secondary caregiver (e.g., teacher, babysitter). The sample is recruited from 12 counties within a 50-mile radius of Iowa City, Iowa.

2.1 Inclusion Criteria

The inclusion criteria for each cohort are:

Cohort 1: 3, 3.75, 4.5, or 5.25 years old
Cohort 2: 3.75, 4.5, 5.25, or 6 years old
Cohort 3: 4.5, 5.25, 6, or 6.75 years old
Cohort 4: 5.25, 6, 6.75, or 7.5 years old

2.2 Exclusion Criteria

The exclusion criteria are:

The child is older than 7.5 years of age (i.e., the child has aged out of study)
Anyone who does not consent
Children whose Primary Caregiver does not speak English
The child does not have normal or corrected-to-normal vision and hearing (i.e., the study tasks would not be valid for assessing the child’s skills)
The child has extremely poor expressive and receptive language skills in English (i.e., the child would not be able to speak or understand basic task instructions)
The child does not have a permanent guardian (i.e., the child is in foster care or is a ward of the State)

3 Research Design

Each participant is assessed every 9 months for each of 4 timepoints, a total of 2¼ years. Lab Visit 1 and Lab Visit 2 are completed approximately one week apart at each timepoint.
