New cross-cultural analysis suggests that g or “general intelligence” is a human universal

By Alex Fradera Intelligence is a concept that some people have a hard time buying. It’s too multifaceted, too context-dependent, too Western. The US psychologist Edwin Boring encapsulated this scepticism when he said “measurable intelligence is simply what the tests of intelligence test.” Yet the scientific credentials of the concept are undimmed, partly because intelligence is strongly associated with so many important outcomes in life. Now Utah Valley University researchers Russell Warne and Cassidy Burningham have released evidence that further strengthens the case for intelligence being a valid and useful concept. Their PsyArXiv pre-print presents a cross-study analysis suggesting a single intelligence-like factor underpins mental performance across a wide range of non-western cultures. Thanks to work pioneered by Charles Spearman, we know that in Western populations performance on a range of mental tasks seems to reflect a more basic mental ability, a “general intelligence” or simply g.  You can’t see g – it’s a statistical reality more than anything else, but it’s very robust, and modern research suggests that the g factor accounts for roughly half the variability in performance within and between people on all kinds of mental tests. Being strong verbally doesn’t guarantee you will be mathematical too, but it tips the odds strongly in your favour.  But it’s conceivable that g is not cultu...

ConclusionsThe use of adhesive can improve masticatory performance of new complete dentures users with normal mandibular ridges in the initial adaptation period up to 60 days after insertion. For resorbed ridges subjects, the use of adhesive had a negative impact on masticatory discomfort/disability OHRQoL at 30 days after insertion.

A 50-year-old man was referred to our hospital for VT. He underwent mechanical aortic and mitral valve replacement for infective endocarditis and embolic myocardial infarction in the left ventricular inferior wall during a surgery. Anti-arrhythmia drugs (AADs) such as sotalol and bisoprolol were initiated and implantable c...

Periaortitis mostly arises from the outer layers of the abdominal aorta and iliac arteries. However, other large arteries may also be involved, but rarely the thoracic aorta. Here we present a successful conservative treatment using prednisolone therapy for periaortitis of the aortic arch which shows various clinical symptoms.
