  When writing software code, developers typically prioritise functionality
over security, either consciously or unconsciously through biases and
heuristics. This is often attributed to tangible pressures such as client
requirements, but little is understood about the psychological dimensions
affecting security behaviours. There is an increasing demand for understanding
how psychological skills affect secure software development and to understand
how these skills themselves are developed during the learning process.
  This doctoral research explores this research space, with aims to identify
important workplace-based skills for software developers; to identify and
empirically investigate the soft skills behind these workplace skills in order
to understand how soft skills can influence security behaviours; and, to
identify ways to introduce and teach soft skills to computer science students
to prepare the future generation of software developers.
  The motivations behind this research are presented alongside the work plan.
Three distinct phases are introduced, along with planned analyses. Phase one is
currently in the data collection stage, with the second phase in planning.
Prior relevant work is highlighted, and the paper concludes with a presentation
of preliminary results and the planned next steps.
