background: previous studies have shown that interaural-time-difference (itd) training can improve localization ability. surprisingly little is, however, known about localization training vis-à-vis speech perception in noise based on interaural time difference in the envelope (itd env). we sought to investigate the reliability of an itd env-based training program in speech-in-noise perception a...

In recent years, the notion that computers and robots will attain superhuman levels of intelligence in the next few decades, ushering in a new “posthuman” era in evolutionary history, has gained widespread attention among technology enthusiasts, thanks in part to books such as Ray Kurzweil’s The Singularity Is Near.

Humans can therefore be expected to possess evolved psychological mechanisms dedicated to controlling fire. Because techniques for starting, maintaining, and using fire differ across ecosystems, the postulated adaptations can be expected to take the ...
