Individuals are not always aware of their mental content. We tested whether lack of awareness occurs in those who have experienced trauma, with and without posttraumatic stress disorder (PTSD). We also examined the role of proposed cognitive mechanisms (working memory and inhibition) in explaining unnoticed intrusions. Individuals with PTSD (n = 44), and varying levels of symptoms (high posttraumatic stress [PTS]: n = 24; low PTS: n = 37) reported on intrusive thoughts throughout a reading task. Intermittently, participants responded to probes about whether their thoughts were trauma related. Participants were “caught” engaging in unreported trauma-related thoughts (unnoticed intrusions) for between 24 and 27% of the probes in the PTSD and high PTS groups, compared with 15% of occasions in the low PTS group. For trauma-related intrusions only, participants lacked meta-awareness for almost 40% of probes in the PTSD group, which was significantly less than that observed in the other groups (~60%). Contrary to predictions, working memory and response inhibition did not predict unnoticed intrusions. The results suggest that individuals who have experienced significant trauma can lack awareness about the frequency of their trauma-related thoughts. Further research is warranted to identify the mechanisms underpinning the occurrence of unnoticed intrusions.  相似文献

Low-income families are more likely to have a child with an early-onset Behavior Disorder (BD); yet, socioeconomic strain challenges engagement in Behavioral Parent Training (BPT). This study follows a promising pilot to further examine the potential to cost-effectively improve low-income families’ engagement in and the efficiency of BPT. Low-income families were randomized to (a) Helping the Noncompliant Child (HNC; McMahon & Forehand, 2003), a weekly, mastery-based BPT program that includes both the parent and child or (b) Technology-Enhanced HNC (TE-HNC), which includes all of the standard HNC components plus a parent mobile application and therapist web portal that provide between-session monitoring, modeling, and coaching of parent skill use with the goal of improved engagement in the context of financial strain. Relative to HNC, TE-HNC families had greater homework compliance and mid-week call participation. TE-HNC completers also required fewer weeks to achieve skill mastery and, in turn, to complete treatment than those in HNC without compromising parent satisfaction with treatment; yet, session attendance and completion were not different between groups. Future directions and clinical implications are discussed.  相似文献

America's judicial system is both exceptionally punitive and demonstrably unjust toward racial minorities. While these dual realities are structured into America's institutions, we propose they are also partially sustained by the intersection of ideologies that are both racialized and sacralized. Using multiple waves of the General Social Surveys and a unique measure that asks Americans to choose between two forms of judicial injustice (wrongful conviction or erroneous acquittal), we examine how white racial identity intersects with biblical literalism to bolster America's bent toward unjust punitiveness. In the main effects, Americans who affirm biblical literalism are more likely to show a preference for convicting the innocent, as are whites compared to Black Americans. Examining interaction effects, however, we find whiteness moderates the influence of biblical literalism such that only white biblical literalists (as opposed to non‐white biblical literalists or white non‐biblical literalists) are more likely to prefer wrongful conviction. Indeed, in our full model, being a white biblical literalist is the strongest predictor of preferring wrongful conviction. We theorize that preference for wrongful conviction over erroneous acquittal stems, at least in part, from the combination of sacralized authoritarianism and perceived racial threat.  相似文献

Most adolescents experiment with alcohol, but a smaller percentage advance to heavy alcohol use (AU) and AU disorder (AUD). Understanding for whom and how early risk leads to AUD is of interest to prevention, treatment, and etiology of AUD. Informed by developmental and behavioral neuroscience theory, the current study tested whether temperament (effortful control, surgency, and negative affect), peer AU (multi-reporter), and AU with parents’ permission interacted to distinguish youth who experiment with alcohol from those who escalate to AUD. Community adolescents (N?=?765, 53% female) were assessed annually for seven years (Mage?=?11.8, range: 10–13 at Year 1; Mage?=?18.7; range?=?17–20 at year 7). Temperament by early experience interactions were expected to predict amount of AU. Amount of AU was expected to mediate the relationship between the interactions and AUD symptoms (assessed at Years 3 and 7, Mage?=?13.8 and 18.7) above and beyond a range of confounds (e.g., problem behavior and parental AU and AUD). Supporting hypotheses, effortful control and surgency interacted with AU with parents’ permission and peer AU, respectively, to predict higher amount of AU (R2?=?0.47) and AUD symptoms (R2?=?0.03). Results support developmental and behavioral neuroscience theory. High surgency and low effortful control in conjunction with peer AU and AU with parents’ permission were associated with large effects on AU and moderate mediated effects through AU to AUD. AU with parents’ permission was risky at low and high effortful control and protective when peers used alcohol.
