2. Careless Responding in Online Survey Research
   We are exploring seven different ways of encouraging study participants to carefully answer survey items in order to prevent the collection of poor-quality data. The study particularly focuses on participants recruited via crowdsourcing websites such as Amazon Turk.
   
   
3. Structural Validation and Development of Norms for the ATTID Scale
   The study uses a large, geographically representative sample to confirm the dimensional structure of the Attitudes Toward Intellectual Disability Scale (ATTID)
