A good conversationalist knows that asking closed-ended questions is no way to make real friends.
Additionally, online testing can be extremely fast and efficient in a way that lab-based testing cannot. This post is a review of things I have learned in the process.
It summarises what I did not know but now wish I had when I was planning my first study and answers some questions I got asked by others along the way. As someone who has learned programming on Guide questions for all experiments own from free online courses, I can confirm that this is not as difficult as some people think it to be and it really is quite fun for some tips on where to get started this TED blog post is quite useful.
At the same time, many people do not know how to code and do not have the time to learn. The good news is that for many experiments, the current survey software available online remains flexible enough to create large number of experiments although the potential complexity is naturally limited.
With online testing, one can reach participants who are simply interested in psychology experiments and volunteering in a way that is preferable to testing psychology undergraduates who are coerced into participating for course credit.
Once you have an experiment to advertise, the challenge is to find the easiest route by which to reach these people. There are many websites that focus directly on advertising online experiments.
The most powerful way for a single individual to reach participants is, quite unsurprisingly, social media. Once a few people start sharing the link, the interest can spread very quickly. The simplest thing to do is to post your study on your Facebook page or Twitter account. One of the biggest successes for me though, remains reddit.
Reddit has a very strong community and people spend time their because they are actively searching for new information and interesting projects. There are a number of subreddits that are specific to psychology so yet again, visited by people interested in these particular topics.
To give a few examples: The last resource I have tried a number of times is using more general advertising sites such as craigslist. In that sense it can be a good place to reach participants and the sample will be fairly diverse. This for me has never been as successful as using social media but a few times it has worked fairly well.
Really what this means is that data collected online might include more noise, making it easier to miss existing effects, than traditional lab-based experiments.
As already mentioned, Crump et al. The range of tasks they have chosen demonstrates nicely that the same results can be obtained in the lab as well as on the Internet. The simplest way is to measure the time participants took to complete the study. If you are using existing survey software, this information is usually automatically provided.
If you are programming the study yourself, requesting a timestamp for when the study begins and for when it ends is an easy way to track the same kind of information.
If participants are abnormally slow or fast in completing a task, then one might have sufficient reasons to exclude the data. One of the biggest problems I have encountered is a participant completing one part of the task e.
As such it can be useful to provide such pointers along the way to make sure participants answer all questions without forcing them to do so. One could simply ask participants to describe briefly what it is that they are expected to do in the experiment.
This way one has data against which to check whether participants understood the instructions and completed the task as anticipated. It will probably also help to ensure that participants pay close attention to the instructions. This is particularly useful if the task is fairly complex.
This means that online testing is definitely most suitable to studies, which are up to 15 or 20 minutes in length to complete and this might be something to consider.
It is also certain that tasks, which are more engaging, will have lower dropout rates. A good incentive I have found is to give participants at the end of an experiment a breakdown of their performance.
I have had many participants confirm that they really enjoyed the feedback on how they performed on the memory task. Such feedback is a simple but efficient way to increase participation and decrease dropout rates.
It is not something that would be common but it could happen.
An experiment is a procedure carried out to support, refute, or validate a tranceformingnlp.comments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale, but always rely on repeatable procedure and logical analysis of the results.
