Prevalence Of Learned Grapheme-Color Pairings In A Large Online Sample Of Synesthetes, Nathan Withhoft, Jonathan Winawer, David M. Eagleman

Faculty Publications

In this paper we estimate the minimum prevalence of grapheme-color synesthetes with letter-color matches learned from an external stimulus, by analyzing a large sample of English-speaking grapheme-color synesthetes. We find that at least 6% (400/6588 participants) of the total sample learned many of their matches from a widely available colored letter toy. Among those born in the decade after the toy began to be manufactured, the proportion of synesthetes with learned letter-color pairings approaches 15% for some 5-year periods. Among those born 5 years or more before it was manufactured, none have colors learned from the toy. Analysis of the …

Dissociation Predicts Later Attention Problems In Sexually Abused Children., Julie B Kaplow, Erin Hall, Karestan C Koenen, Kenneth A Dodge, Lisa Amaya-Jackson

Faculty Publications

OBJECTIVE: The goals of this research are to develop and test a prospective model of attention problems in sexually abused children that includes fixed variables (e.g., gender), trauma, and disclosure-related pathways.

METHODS: At Time 1, fixed variables, trauma variables, and stress reactions upon disclosure were assessed in 156 children aged 8-13 years. At the Time 2 follow-up (8-36 months following the initial interview), 56 of the children were assessed for attention problems.

RESULTS: A path analysis involving a series of hierarchically nested, ordinary least squares multiple regression analyses indicated two direct paths to attention problems including the child's relationship to …

Pathways To Ptsd, Part Ii: Sexually Abused Children., Julie B Kaplow, Kenneth A Dodge, Lisa Amaya-Jackson, Glenn N Saxe

Faculty Publications

OBJECTIVE: The goal of this research was to develop and test a prospective model of posttraumatic stress symptoms in sexually abused children that includes pretrauma, trauma, and disclosure-related pathways.

METHOD: At time 1, several measures were used to assess pretrauma variables, trauma variables, and stress reactions upon disclosure for 156 sexually abused children ages 8 to 13 years. At the time 2 follow-up (7 to 36 months following the initial interview), the children were assessed for posttraumatic stress disorder (PTSD) symptoms.

RESULTS: A path analysis involving a series of hierarchically nested ordinary least squares multiple regression analyses indicated three direct …

A 12-Year Prospective Study Of The Long-Term Effects Of Early Child Physical Maltreatment On Psychological, Behavioral, And Academic Problems In Adolescence., Jennifer E Lansford, Kenneth A Dodge, Gregory S Pettit, John E Bates, Joseph Crozier, Julie Kaplow

Faculty Publications

OBJECTIVE: To determine whether child physical maltreatment early in life has long-term effects on psychological, behavioral, and academic problems independent of other characteristics associated with maltreatment.

DESIGN: Prospective longitudinal study with data collected annually from 1987 through 1999.

SETTING AND PARTICIPANTS: Randomly selected, community-based samples of 585 children from the ongoing Child Development Project were recruited the summer before children entered kindergarten in 3 geographic sites. Seventy-nine percent continued to participate in grade 11. The initial in-home interviews revealed that 69 children (11.8%) had experienced physical maltreatment prior to kindergarten matriculation.

MAIN OUTCOME MEASURES: Adolescent assessment of school grades, standardized …

Child, Parent, And Peer Predictors Of Early-Onset Substance Use: A Multisite Longitudinal Study, Julie B Kaplow, Patrick J Curran, Kenneth A Dodge

Faculty Publications

The purpose of this study was to identify kindergarten-age predictors of early-onset substance use from demographic, environmental, parenting, child psychological, behavioral, and social functioning domains. Data from a longitudinal study of 295 children were gathered using multiple-assessment methods and multiple informants in kindergarten and 1st grade. Annual assessments at ages 10, 11, and 12 reflected that 21% of children reported having initiated substance use by age 12. Results from longitudinal logistic regression models indicated that risk factors at kindergarten include being male, having a parent who abused substances, lower levels of parental verbal reasoning, higher levels of overactivity, more thought …
