Local Violence, Attention, and Impulse Control (Sharkey et al., 2012)

A Chicago preschool study linked a nearby homicide in the prior week with lower attention, impulse control, and preacademic scores in the study sample.

What it means

Using Chicago School Readiness Project data from 2004–2006, researchers studied preschoolers in Head Start programs. Children assessed within a week of a homicide near home showed lower attention, impulse control, and preacademic skills. Caregiver distress also increased; the authors describe it as suggestive evidence for a possible pathway.

This study concerns acute outcomes in a specific Chicago preschool sample. It supports describing how nearby violence can interfere with self-regulation and readiness to learn; it does not establish permanent effects for all children.

See how this idea helps with a decision

Here is an example to work through. The linked source explains the idea or guest account. The next move is ICM guidance.

Where it shows up
An early-learning team is deciding how to respond when a violent incident occurs near a child's home shortly before classroom assessment.
A useful move
Review the study's one-week window and measures of attention, impulse control, and preacademic skills; use them to consider practical support for regulation and readiness, then check what children need locally.
What this does not prove
The evidence comes from Chicago preschoolers in Head Start; caregiver distress was a suggestive pathway, not a proven explanation for every child's response.
