Overview of today’s lab activities

Ethics II & Reliability and Validity

This week has two major areas of focus - a deeper dive on the Ethics Application Portal, including information that will be required, and to recap Psychometric Reliability and Validity.

By the end of the session, you will have:

This week is focused on the following overarching learning objectives

  • Be fully prepared to submit a successful Ethics Application
  • Understand and be able to critically assess the strengths and limitations of psychological measures in terms of their reliability and validity.

Two main parts of the lab this week

Activities for this week

Ethics II

Familiarise yourself with the important Ethics resources available on the VLE. These include general Research guidelines, but some specific to online research too (should you plan to work online only).

Successfully logging in to the Goldsmiths Research Ethics portal and reviewing all the information you will be required to submit in support of your ethics application. By being aware of this, you can offset any problems.

Please pay close attention to detail

Any errors will result in an application being returned and a resubmission will be required.

Please see the worksheet on the VLE for detailed guidance

Reliability and Validity

The Worksheet this week has a comprehensive overview of 4 Validities and 4 Reliabilities, as well as ways to accentuate the quality of research tools.

This material is designed to poiint you towards more focussed assessments of research tools than you may have been considering up to this point.

It is not usually good enough to say “this tool lacks validity” - you need to go much deeper and argue your assessment.
