Marriage amendments and psychological distress in lesbian, gay, and bisexual (LGB) adults.

Abstract: An online survey of lesbian, gay, and bisexual (LGB) adults (N = 1,552) examined minority stress (I. H. Meyer, 2003) and psychological distress following the 2006 general election in which constitutional amendments to limit marriage to 1 man and 1 woman were on the ballot in 9 states. Following the November election, participants living in states that passed a marriage amendment reported significantly more minority stress (i.e., exposure to negative media messages and negative conversations, negative amendment-related affect, and LGB activism) and higher levels of psychological distress (negative affect, stress, and depressive symptoms) than participants living in the other states. Multiple hierarchical regression analyses revealed significant positive main effects of minority stress factors and state ballot status on psychological distress. In addition, the association between amendment-related affect and psychological distress was significantly higher in states that had passed a marriage amendment compared with other states. Discussion of these findings emphasizes that marriage amendments create an environment associated with negative psychological outcomes for LGB individuals.

Coh-Metrix: Capturing Linguistic Features of Cohesion

Abstract: This study addresses the need in discourse psychology for computational techniques that analyze text on multiple levels of cohesion and text difficulty. Discourse psychologists often investigate phenomena related to discourse processing using lengthy texts containing multiple paragraphs, as opposed to single word and sentence stimuli. Characterizing such texts in terms of cohesion and coherence is challenging. Some computational tools are available, but they are either fragmented over different databases or they assess single, specific features of text. Coh-Metrix is a computational linguistic tool that measures text cohesion and text difficulty on a range of word, sentence, paragraph, and discourse dimensions. This study investigated the validity of Coh-Metrix as a measure of cohesion in text using stimuli from published discourse psychology studies as a benchmark. Results showed that Coh-Metrix indexes of cohesion (individually and combined) significantly distinguished the high- versus low-cohesion vers...

A Social Feedback Loop for Speech Development and Its Reduction in Autism

Abstract: We analyzed the microstructure of child-adult interaction during naturalistic, daylong, automatically labeled audio recordings (13,836 hr total) of children (8- to 48-month-olds) with and without autism. We found that an adult was more likely to respond when the child's vocalization was speech related rather than not speech related. In turn, a child's vocalization was more likely to be speech related if the child's previous speech-related vocalization had received an immediate adult response rather than no response. Taken together, these results are consistent with the idea that there is a social feedback loop between child and caregiver that promotes speech development. Although this feedback loop applies in both typical development and autism, children with autism produced proportionally fewer speech-related vocalizations, and the responses they received were less contingent on whether their vocalizations were speech related. We argue that such differences will diminish the strength of the social feedback loop and have cascading effects on speech development over time. Differences related to socioeconomic status are also reported.
