BACKGROUND Although differences in brain anatomy in autism have been difficult to replicate using manual tracing methods, automated whole brain analyses have begun to find consistent differences in regions of the brain associated with the social cognitive processes that are often impaired in autism. We attempted to replicate these whole brain studies and to(More)
Language difficulties have been implicated to be a part of the broad autism phenotype in first-degree relatives of individuals with autism. Phonological processing difficulties in particular have been reported by some, but not all groups studying parents or siblings of probands with autism. In the present study, we examined a broad battery of language tasks(More)
BACKGROUND Synchronous neural oscillatory activity in the gamma range (30-80 Hz) has been shown to be abnormal in individuals with autism spectrum disorders (ASD) and their first-degree relatives in response to simple auditory stimuli. Gamma-band abnormalities in ASD probands have been seen in response to language stimuli, but this has not been investigated(More)
Previous structural imaging studies of autistic individuals have identified gray matter abnormalities. It remains unclear, however, which abnormalities contribute to the etiology of autism and, among these abnormalities, which reflect genetic factors. Using voxel-based morphometry, we compared regional gray matter volume in 23 parents of autistic children(More)
Friendship factors have been implicated in adolescent suicidality, but this relationship has not been verified across ethnicities. This study examined suicidality and friendship problems (i.e., social isolation, poor friendship quality, friends' school disconnection, and friends' delinquency) among Mexican American adolescents, an understudied, vulnerable(More)
Research suggests a link between friendships and suicidality among U.S. youth, but this link has not been confirmed across ethnicities. The relationship between friendships and suicidality among Mexican American and European American adolescents was examined in this study. Specifically, the role of friendship problems (i.e., social isolation, poor quality(More)
During adolescence, friends are increasingly important for support and values. Do friends also have a long-term impact on suicidality? This study explored the role of friendship problems (e.g., social isolation) and deviant friends during late adolescence on suicidal ideation and behavior 3 years later. Participants were 295 community adolescents (59 %(More)
OBJECTIVES In the United States, suicide rates are highest among European American older adults. This phenomenon calls attention to cultural factors, specifically, the suicide beliefs and attitudes of European Americans. Beliefs and attitudes matter in the vulnerability to suicide. As predicted by cultural scripts of suicide theory, suicide is most likely(More)
