Pensieve: Technologies to Support Reminiscence

You are invited to take part in a research study of how technologies can help people remember the past.

What the study is about

The purpose of this study is to study a tool we have developed to help people remember to reminisce, using information they have placed on the web as well as general prompts to support reminiscing. Many people report that they do not spend enough time remembering the past.

What we will ask you to do

If you agree to be in this study, we will send you one to three emails per day containing a prompt related to the study. Some of these prompts will be general reminders to reminisce; a few will include questions that ask you about your reminiscing; and if you give us permission, we will use content from your own blogs, flickr photos, or Facebook account to generate the prompts. You are encouraged to reply to these emails whenever you have anything you would like to tell us about the prompt, your reminiscing, or the project in general. The study will last as long as you would like to keep receiving the prompts.

Risks and benefits

We hope that the tool will help you make more effective use of your digital memories and reminisce in ways that on balance will make you happier. The tool will not be able to tell, however, whether a particular picture or blog post might trigger good or bad memories for you, so there is some chance it will present things that might bring back unpleasant memories.

In the research papers we hope to produce from this study, we will likely want to include both interview quotes and information that is sent to participants. We will make every effort to ensure that your identity cannot be inferred from the information in those quotes and snippets, including carefully choosing information we think is not identifying and anonymizing the quotes, but we cannot promise absolute confidentiality in this way.

Finally, because this study takes place over the internet, it is possible, though unlikely, that other people may intercept and read the emails we send with prompts and content, as well as any responses you provide.


There is no compensation for this study.
