I'm working on the SMILE project and I'm wondering how I should cite my articles.
Use the following example to format the citation for your primary article:
Powell, K.L., Roberts, G., & Nettle, D. 2012. Eye images increase charitable donations: evidence from an opportunistic field experiment in a supermarket. Ethology, 118, 1096-1101.
And use the following example to format the citation for your secondary article:
Foley, James A. 2013. Chimps feeding habits suggests long-term memory use. Nature World News. October 24, 2013.
Alternately, you could also follow this general format: Last name, First name M.I. Year. Article or Chapter Title. Page numbers. Journal Title.
