Abstract

Evidence from physiological studies has been integral in many causal theories of behavioral and emotional problems. However, this evidence is hampered by the heterogeneity characterizing these problems. The current study adds to prior work by identifying neuro-physiological markers associated with heterogeneity in conduct problems (CP), callous-unemotional (CU) traits, and anxiety. Participants were classified into the following groups: (a) low risk, (b) anxious (predominately high anxiety), (c) primary (scored high on CP and CU traits but low on anxiety), and (d) secondary (high anxiety, CU traits, and CP). Developmental differences were also examined by including two different samples assessed during young adulthood (Study 1: n = 88; Mage = 19.92; 50% female) and childhood (Study 2: n = 72; Mage = 5.78, SD = 1.33; 39 males). Participants in both studies were recruited from community samples (Study 1: n = 2,306; Mage = 16, SD = .89; Study 2: n = 850; Mage = 5.01, SD = .95). Physiological responses (heart rate, skin conductance, startle modulation) were recorded while children and adults watched negative affective and neutral scenes. Medial prefrontal activation (oxygenated hemoglobin) was also measured in young adults. Finding...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
