Individual differences in higher-level cognitive abilities do not predict overconfidence in complex task performance.

Even when people perform tasks poorly, they often report unrealistically positive estimates of their own abilities in these situations. To better understand the origins of such overconfidence, we investigated whether it could be predicted by individual differences in working memory, attentional control, and self-reported trait impulsivity. Overconfidence was estimated by contrasting objective and subjective measures of situation awareness (the ability to perceive and understand task-relevant information in the environment), acquired during a challenging air traffic control simulation. We found no significant relationships between overconfidence and either working memory or attentional control. However, increased impulsivity significantly predicted greater overconfidence. In addition, overall levels of overconfidence were lower in our complex task than in previous studies that used less-complex lab-based tasks. Our results suggest that overconfidence may not be linked to high-level cognitive abilities, but that dynamic tasks with frequent opportunities for performance feedback may reduce misconceptions about personal performance.

Should I trust you? Autistic traits predict reduced appearance-based trust decisions.

Facial impressions of trustworthiness guide social decisions in the general population, as shown by financial lending in economic Trust Games. As an exception, autistic boys fail to use facial impressions to guide trust decisions, despite forming typical facial trustworthiness impressions (Autism, 19, 2015a, 1002). Here, we tested whether this dissociation between forming and using facial impressions of trustworthiness extends to neurotypical men with high levels of autistic traits. Forty-six Caucasian men completed a multi-turn Trust Game, a facial trustworthiness impressions task, the Autism-Spectrum Quotient, and two Theory of Mind tasks. As hypothesized, participants' levels of autistic traits had no observed effect on the impressions formed, but negatively predicted the use of those impressions in trust decisions. Thus, the dissociation between forming and using facial impressions of trustworthiness extends to the broader autism phenotype. More broadly, our results identify autistic traits as an important source of individual variation in the use of facial impressions to guide behaviour. Interestingly, failure to use these impressions could potentially represent rational behaviour, given their limited validity.

Evaluation of Mental Health First Aid skills in an Australian university population.

AIM: University students have high rates of mental health problems; however, most delay or fail to seek help altogether. Tertiary settings can offer educational and social programmes to increase mental health awareness and in turn increase the number of students seeking help for their problems. This study aimed to explore students' and staffs' knowledge of mental health issues, confidence to intervene and application of skills following Mental Health First Aid (MHFA) training. METHODS: Students and staff at an Australian university who had completed MHFA training in the previous 24 months were invited to complete a validated online questionnaire. RESULTS: Of the 566 eligible participants, 107 (19%) completed the questionnaire. The majority (65%) had applied their skills to someone in need, with the highest number applying it to students. Notably, of those who had applied their skills 23 participants (33%) had applied them in a crisis situation, the most common being panic attacks followed by suicidal thoughts. Although most (98%) applied their skills in a face-to-face capacity, 53% also reported assisting someone via electronic mediums and social media. The mean score for the literacy test was considered high, 12/16 (SD = 1.7) for students and 13/16 (SD = 2.5) for staff. The majority (94%) reported more confidence in providing support following training. CONCLUSION: This study demonstrated that MHFA training on a university campus is associated with a high level of knowledge, confidence to intervene and apply MHFA skills to assist a student or friend in need, potentially impacting their long-term health outcomes and future professional careers.
