Abstract

In the last 50 years, the study of brain development has brought major discoveries to education and medicine, changing the lives of millions of children and families. However, collecting behavioral and neurophysiological data from children has specific challenges, such as high rates of data loss and participant dropout. We have developed a science camp method to collect data from children using the benefits of positive peer interactions and interactive and engaging activities, to allow researchers to better collect data repeatedly and reliably from groups of children. A key advantage of this approach is that by increasing participant engagement, attention is also increased, thereby increasing data quality, reducing data loss, and lowering attrition rates. This protocol describes the step-by-step procedure for facilitation of a science camp, including behavioral, electrophysiological, and participatory engagement activities. As this method is robust but also flexible, we anticipate that it can also be applied to different demographics and research needs.

Before start

Planning

1 Research Team

The large number of participants’ data typically collected using this method requires a large group of researchers. The group of assistants could be academics, clinicians, clinical staff, community professionals, and/or students. All should follow a proper experimental training to conduct the tasks of the protocol and understand how to work with children (including clinical child populations if necessary). All must have completed criminal background checks prior to data collection. Once the background checks have been approved, assistants should sign an agreement of collaboration and participate in the specific training sessions offered by the research group. The training should include an experimental aspect and a clinical aspect (if needed). The experimental aspect of the training should evaluate the previous knowledge of the research team members and create a plan to provide the knowledge they are missing. 

After the training, all research team members should be prepared for the activity they were assigned. The group assigned to the administration of psychometric tests should complete the required training for each test (i.e., training varies greatly depending on the test). The groups assigned to a behavioral test that requires the use of a computer and electrophysiological measurement system, or any other equipment designed to make physiological recordings from participants should know how to connect and test all equipment; how to properly manipulate and clean them; how to run the task and record the data.In addition, they should know what to do if the participants refuse to participate in the activity (i.e., What room to direct the participants, what activities to offer instead, etc.).

2 Piloting

Several pilot testing sessions might be needed until all the assistants are capable of mastering the procedures and can do so in a specific timeframe. In the first pilot session, it is recommended that research team members take turns role-playing as participants, as children are not present at this stage. During the clinical part of the pilot stage, general and specific aspects of working with children should be included. Clear rules and expected behavior should always be stated from the beginning.

All research team members should know the characteristics of the group that they will work with and be prepared to act according to the participant’s needs, triggers, and level of functioning. One strategy to support this learning phase is to present case studies that represent different situations that teach assistants how to respond to each one. The pilot stage should be repeated as much as needed by the research team members.

3 One Day Prior

In order to ensure a successful group data collection, it is important to set up all data collection stations and run the experiments at least once on the day before the experiment, allowing the research group enough time to solve any last-minute issues that could arise. The research team members should receive clear instructions about who and how to contact for help if specific problems arise. Necessary checklists and information sheets should be provided for each research team member.

4 Day of the Data Collection

The day starts with an entry meeting in which the children and their parents are welcomed. All the parents sit down and receive a presentation (i.e., using pictures and videos) with the description of each activity and how the science camp works. Children are grouped within their age range. The research team provides children with their name tags and working materials such as t-shirts with different colors per group. The groups are gathered, and the parents and the children are introduced to their group leader (i.e., a research team member in charge of that group) and to their group mates. Time should be allotted to answer questions from parents and children. After introductions, children receive a card to help them collect one sticker for each activity completed. Research team members then lead their groups through the circuit of the science camp. Each group leader will stay the whole day with their group. It provides stability and reassurance for the children.Parents are welcome to stay in the registration room and participate in workshops, or they can run errands and come back before the exit meeting.At the end of the day, the protocol ends with an exit meeting. During this meeting, all groups of children, research team members and parents are reunited for a debriefing and answer any questions they may have. A recap of the event (i.e., showing pictures of the event to the parents) and prizes are provided. The research team will also inform the parents when they will be able to receive a report of the day.No individual report is shared with participant information but a global day description of what the children have done during the science camp protocol explaining the goal of the studies is encouraged to create a long-term relationship with the parents and their child.

4.1 Data Acquisition

To achieve a science camp protocol, we carefully planned a step-by-step one-day agenda. Different rooms are conditioned for different activities (see example in Fig 1). During the camp (approximately 9:00 a.m. to 5:00 p.m.), participants visit each of the stations where they will perform research-related and non-research related activities.Depending on the research question and the characteristics of the participants' population, the activities, set up, and duration should be adapted.They will receive breaks in between each activity to be able to rest and engage with other participants (see example in Fig 2).  In addition to the research and fun stations, it is necessary to prepare a room big enough to hold meetings with all the parents and participants.Fun station are two extra rooms for breaks, in these rooms there is always a research team member prepared to receive any participants who need a break. One of them is called the calm room; this room is always quiet. The second room is called the playroom; in this room, participants can take a break from the planned activities, and they have some extra options for fun activities to participate in (i.e., play board games, sing, draw or work on crafts).

In summary, the implementation of a science camp protocol will typically use at least three different types of stations. The first is for the behavioural evaluations; the second is the ‘fun’ stations, and the third is the electrophysiological station.

4.2 Science camp behavioral assessment The configuration of the rooms allows us to have the required privacy for psychometrics application or behavioural assessment simultaneously. It is important to have separate workstations with light divisions (i.e., Wood or plastic panels) to prevent children from interfering with each other’s activities in the same room (please see example in Fig 3).

4.3 Science camp electrophysiology recordings

For the EEG station, our research group uses 5 EEG systems (i.e., the number of systems will depend on the space possibilities). The EEG station should be located in a room where EEG systems can be at least 3 meters apart and have one cleaning station in the center of the room (See Fig 4). Our data verification tests showed that 3 meters was enough to effectively minimize the signal contamination between systems. Having the cleaning station in the center of the room is convenient towards preparation of the stations between groups.After the accent of the participants, they are guided to their station (one per participant). Two research assistants manage each station (i.e., two research assistants per station and participant). Within the first 20 minutes, the two research assistants explain the tasks' instructions to each participant and prepare the settings (i.e., capping the participants and training them on the task).In this setup, an essential factor is the orientation of the participants (i.e., not seeing each other), as this will limit the distraction and subsequent loss of data. During this time (the first 20 minutes), participants are also allowed to talk with the research assistants and move in their seats. For some participants, research assistants could also propose watching a short children's movie to the participants.The total length of the EEG recording depends on the research questions, task design and population. Previous tasks with children for our research group lasted up to 30 minutes, providing breaks between experimental blocks to allow them to stretch and move in their seats. Between groups, 15 minutes are necessary to clean and prepare the settings for the next group.In total, 13 research assistants are needed in this station example. Each EEG system is operated by 2 research assistants. There is also one assistant coordinating the groups’ transitions, overseeing the overall data collection, and providing extra support if needed, another assistant ready to provide technical support and one more assistant working exclusively in the cleaning station preparing the supplies for all the groups.

4.4 Science camp fun stations

These rooms can have a flexible configuration, but they should be safe for child play. These stations are where the participants have fun and interact with each other. For example, they can play board games, sing, draw or work on crafts. These stations can be adapted to the space and to the activities available and best suited to the participant populations. There is no need for a special configuration or separation between participants.
