Commentary: Wild psychometrics: Evidence for ‘general’ cognitive performance in wild New Zealand robins, Petroica longipes

Studies into the psychometric structure of human intelligence and cognitive ability have identified a " g " or general factor, e.g., Buckhalt (2002), and in comparative psychology, in primates: Reader et al. (2011) and in rodents: Matzel et al. (2003). As well as this " g " factor, intelligence is conceptualized as possessing multiple specific intelligences. Due perhaps to more recent discoveri...

Individual differences in cognitive flexibility.

I s it better to be flexible, or persistent? A colleague once said that the secret to success in science is perseveration (no, not mere perseverence—that wouldn’t get you very far at all). Yet we all believe that the highest levels of cognitive function are associated with extreme flexibility—the ability to juggle many things at once and not get hung up on just one. Indeed, this ability to jugg...

Individual differences in cognitive arithmetic.

Unities in the processes involved in solving arithmetic problems of varying operations have been suggested by studies that have used both factor-analytic and information-processing methods. We designed the present study to investigate the convergence of mental processes assessed by paper-and-pencil measures defining the Numerical Facility factor and component processes for cognitive arithmetic ...
