We are interested studying the effects of sleep loss on attention and emotion. In this study, some people will be asked to restrict their sleep to 4 hours on one night, while others will be asked to sleep for 8 hours. Participants will then be asked to spend one afternoon in the Sleep Research Laboratory where EEG will be recorded to measure brain activity while performing various computer tasks of attention and emotion.
Here are the details of what would be expected of you:
1. First, we will get some information from you on the phone today to see if you meet our basic criteria for participation.
2. If you are suitable for the study, we will then ask you to attend a 1 1/2-hr ORIENTATION session where you will tour the Sleep Lab, and be given a full consent form – this provides details about the study – and you can decide whether or not you are interested in full participation at that time. You will then complete a series of questionnaires, have your heart rate recorded, and practice the computerized cognitive tasks that we will use in the main study. The questionnaires will ask questions about your physical and mental health, sleep habits and personality. These questionnaires will confirm that you meet all of the eligibility requirements for this study.
3. If you wish to participate, you will then be asked to complete a sleep/wake diary from home each morning and wear an Activity Monitor (that looks like a wrist watch) for a period of one week prior to participation in the study. You will be asked to keep a regular sleep/wake schedule that week, sleeping for about 8 hrs each night from approximately 11pm-7am (or midnight-8am).
If you are deemed ineligible or if you choose not to participate in the laboratory study, there will be no compensation for the pre-study screening (that is, the orientation session, and sleep diaries/activity monitor for the week prior to the main study day). If you do not complete the main part of the study for whatever reason, all of the information you provided in pre-study screening will be destroyed.
4. For the main part of the study, you will be scheduled to spend one afternoon in the Sleep Laboratory, from 1-6pm for a performance assessment. You will have your brain activity recorded using an electrode cap while performing computer tasks. You will also be asked to provide saliva samples at various times by spitting into a test tube because we are measuring hormones. Also, you may or may not be asked to restrict your sleep on the prior night.
Are you interested? [yes] – Ok, I have a few questions for you to make sure you are suitable for the study. If you are the type of person we are looking for, we will schedule your orientation appointment.
