According to the newly published sixth edition of APA publication manual (p 73), people who participate in an experiment are no longer referred to solely as participants. They can now referred to as participants and subjects. Originally, people were referred to as subjects, and at some point the term participant was adopted and the term subject was reserved for animals (I’m not a historian).
It’s nice that we are “allowed” to use the term subjects again as it is consistent with the long standing acronym Ss.
