I am so sorry for asking, but i have been unable to find a solution (and i've tried hard). When i add a @author syntax in my rmarkdown script (corresponding to my created bib.file) and knit the file the authors are cited correctly. But when i cite the authors the next time it does not do author et al. (year) but displays all authors again! I have already tried loading other publkic available .rmd and .bib files (that have appropriate citations) but when i knit them myself, the same problem appears. How can i fix this?
I would really appreciate any advices, thanks in advance! <3
Edit: For example, a BibTex entry would look like this:
@article{Zygar-Hoffmann2018,author = {Zygar-Hoffmann, Caroline and Hagemeyer, Birk and Pusch, Sebastian and Sch{\"{o}}nbrodt, Felix D.}, doi = {10.1002/per.2145}, journal = {European Journal of Personality}, number = {3}, pages = {306--324},title = {{From Motive Dispositions to States to Outcomes: An Intensive Experience Sampling Study on Communal Motivational Dynamics in Couples}}, volume = {32}, year = {2018} }.
An in my rmarkdown (papaja template) text i write:
The influence of rather stable motives on behavior is proposed to be (fully) mediated by the current motivation [@Zygar-Hoffmann2018]. The latter describes a varying state that results from an individual’s motive, the current situation and their interaction [@Zygar-Hoffmann2018].
Now i would expect that when knitting the second citation appeared as "Zygar et al. (2018)" but unfortunately it doesn't. I have the latest Version of R, RStudio, MacTex and Mac OS Big Sur installed.
