Genetic and environmental correlations among 11 Wechsler Intelligence Scale for Children-Revised (WISC-R) subtests were estimated from a sample of 143 twin pairs using the methodology of multivariate behavioral genetics. The genetic correlations among subtests varied in magnitude and exhibited a pattern similar to corresponding phenotypic correlations. Correlations due to within-pair environmen...

Current techniques of repeated suicide risk assessment are not reliably predictive, and research into new methods is needed. The judgment of clinicians relies partly on nonverbal signs such as facial expressions. If differences in patients and/or interviewer's facial expressions appeared between subjects who were to make subsequent attempts (Repeaters) and those who were not (NonRepeaters), thi...

The RiskTrack project aims to help in the prevention of terrorism through the identification of online radicalisation. In line with the European Union priorities in this matter, this project has been designed to identify and tackle the indicators that raise a red flag about which individuals or communities are being radicalised and recruited to commit violent acts of terrorism. Therefore, the m...

Behavioral medicine research often seeks to examine relatively complex theoretical models and clinical processes. Traditional designs, based on retrospective self-report in the natural environment or laboratory-based studies, cannot assess complex and temporally dynamic psychological, behavioral, and physiological processes in the natural environment. An alternate research approach, Ecological ...

OBJECTIVES Following studies conducted during the immediate newborn stage, we investigated whether one-week-olds' neurobehavioral functioning was differentiated by feeding method. We also examined whether feeding-method effects differed among infants of adolescent mothers. METHOD Participants were infants (N = 83) of breast-feeding (N = 41) and formula-feeding (N = 42) mothers. Approximately ...
