(Attention warning: massive speculation ahead.) Auguries often seem made up, useless. Is that why they are useful? Dove figured that the birds must be serving as some kind of ecological indicator. Perhaps they gravitated toward good soil, or smaller trees, or some other useful characteristic of a swidden site. After all, the Kantu’ had been […]... Read more »

Attention deficit hyperactivity disorder (ADHD), characterized by inattention, hyperactivity, and impulsivity, is a common childhood disorder. ADHD can often persist into adolescence and adulthood. The prevalence of ADHD is thought to be between 6-7% among children and adolescents and ~5% among adults (Willcutt, 2012).
Increasingly, evidence from multiple studies has pointed to comorbidity between ADHD and eating disorders (EDs). For example, one study found that young females with ADHD we........ Read more »

How well can psychotherapists and their clients judge from personal experience whether therapy has been effective? Not well at all, according to a paper by Scott Lilienfeld and his colleagues. The fear is that this can lead to the continued practice of ineffective, or even harmful, treatments.The authors point out that, like the rest of us, clinicians are subject to four main biases that skew their ability to infer the effectiveness of their psychotherapeutic treatments. This includes the mistak........ Read more »

Acknowledging that some topics have the ability to furrow brows when it comes to autism research, mercury and autism is becoming something of a frequent talking point on this blog as a function of a whole slew of articles appearing in the peer-reviewed domain. If I were to [very tentatively] summarise the collected literature so far, it would be to say something like:Mosaic of mercury @ Wikipedia (i) there is quite a bit more research to be done on some sources of mercury being 'l........

Are we selfish? Economists like to say that, to a first approximation, we are. In other words, that we tend to seek to maximize our own rewards, in a more or less rational manner. The trouble is that this theory (at least, a straightforward interpretation of it) doesn’t describe how people behave in many situations.

We expect of our jurors and judges calm, reasoned evaluation of the evidence. Of course we know the reality is rather different - prejudice and emotional reactions will always play their part. Now two new studies add insight into the ways people's legal judgements depart from cool objectivity.Beatrice Capestany and Lasana Harris focused on two main factors - the disgust level of a crime, and whether or not the perpetrators' personality was described in biological terms. Seventeen participants we........ Read more »

It’s hard to find the best person for the job through an interview. New research uncovers part of the problem: judging a candidate’s calibre becomes trickier when we’re also trying to sell them the benefits of joining the organisation.In an initial study, participants were asked to interview a person (another participant) who was acting as an applicant for a fictional position. Half the interviewers were told their priority was to get a good sense of the applicant, while the rest had to pr........ Read more »
