Psychiatric disorder in the children of antisocial parents.

Background: Although parents with psychiatric disorders are likely to have children with psychiatric problems, the nature of disorder risk to offspring of antisocial parents has received limited attention.

Method: We examined the prevalence of common externalizing and internalizing disorders in the pre-adolescent and late adolescent offspring of antisocial parents. Lifetime diagnoses for a sample of 11-year-old twins (958 males, 1042 females) and a sample of 17-year-old twins (1332 males, 1434 females), as well as their parents, were obtained through in-person interviews.

Genetic and environmental influences on adolescents' perceptions of current family environment.

Previous studies of the genetic and environmental components of the Family Environment Scale (FES) have typically reported that scales relating to familial acceptance are moderately to strongly genetically influenced while measures of control are more environmentally influenced. These reports relied on retrospective recall, which is not as reliable as recall of current environment. To investigate the genetic contribution to contemporaneous perceptions of one's rearing environment, the responses on the FES of 471 17-year-old male twins (141 complete MZ twin pairs, 73 complete DZ twin pairs, 43 incomplete twin pairs) participating in the Minnesota Twin-Family Study (MTFS) were analyzed.

Neural correlates of age-related declines in the formation and realization of delayed intentions.

Neural correlates of age-related declines in prospective memory were studied by using event-related brain potentials (ERPs) in a task in which individuals formed and later realized simple intentions. The behavioral data revealed that prospective responding was less accurate and slower in older than in younger adults. The electrophysiological data revealed age-related differences in the amplitude of modulations of the ERPs associated with the encoding of intentions, the detection of cues, and disengagement from the ongoing activity.

Effects of intention load and background context on prospective remembering: an event-related brain potential study.

Prospective remembering reflects the ability to realize intentions that must be delayed over some period of time. Recent evidence indicates that distinct modulations of the event-related brain potentials may be associated with the detection of a prospective memory cue (N300) and the recovery of an intention from memory (LPC, slow wave). The present experiments examined the degree to which these modulations were influenced by task manipulations that were expected to differentially influence cue detection and memory-related processes.
