Over the past decade, research in psychology, sociology, and economics has begun to incorporate online participant pools to varying extents. These online pools allow experimenters to increase the sample size and diversity of their participant groups, while also enabling experiments that would be nearly impossible to conduct in the lab, for example exploring interactions between thousands of participants within social networks.
Consonance is a fundamental aspect of music perception that has been studied for many centuries. Most of this work relies heavily on musical stimuli drawn from quantized musical scales (e.g., 12-tone equal temperament, or the Bohlen-Pierce scale), synthesized either using idealized harmonic complex tones or Western instrument sounds (e.g., piano, clarinet).
Over 90% of psychology experiments between 2003-2007 were conducted on WEIRD subjects, hailing from Western, Educated, Industrialized, Rich, and Democratic societies (Arnett 2008). Henrich et al. (2010) have argued that these populations constitute an extremely biased sample across several critical dimensions, manifested in paradigms from basic visual and spatial perception to social cognition.
As cognitive scientists, we are often interested in mapping the relationship between external stimuli (e.g., spoken sentences, musical chords, faces) and semantic features that the mind derives from these stimuli (e.g., happiness, sadness, pleasantness).
Sensorimotor synchronization (SMS), the rhythmic coordination of perception and action, is a fundamental human skill that supports many behaviors, from repetitive daily routines to the highest forms of behavioural coordination, including music and dance (see Repp, 2005; Repp & Su, 2013, for reviews).
Culture is deep inside us, in our ability to speak, in our sense of belonging, in our values. The capacity of our brain to adapt to and integrate culture is what makes us human: from birth, our mind is set to absorb concepts, technologies and social conventions that accumulated over thousands of generations.
