The focus of the study is to identify children with word-finding difficulty and other speech and communication difficulties such as stuttering, a procedure referred to as screening. Ideally, investigators want to screen all children in the reception classes in the schools with which investigators work. The procedures were designed so that they work with children who speak English or those whose first language is not English. A second aim concerns what teachers can do when a child does not pass the screen. Investigators have developed a type of treatment designed for children who have either word-finding difficulty or fluency difficulty. This project concerns the intervention for children with word-finding difficulty.

The treatment is conducted in a quiet room with pairs of children. The children with word-finding difficulty in each group are assessed individually for about 10 min before the treatment starts to establish a baseline for assessing improvement using a standardized task that tests for word-finding difficulty. A recording is taken, similar to that investigators obtained at the screening phase. The training takes place over three weeks (one session a week of 20-30 minutes' duration). Word-finding difficulty and fluency are reassessed at the end of the three-week period and at follow-up one week later.

The researcher will visit every participating child at school for approximately 10 minutes. Prior to that, the researcher will speak to the child's teacher to ensure that the sessions do not clash with any important class activities. Each child will be seen individually and will listen to a number of "nonsense" words one by one and will be asked to repeat the word. The child will be told that these are funny sounding made up word. The child will be audio-recorded while speaking to the researcher.

Each audio recording is then analysed anonymously at UCL for signs of fluency or word finding difficulty. All children occasionally show these signs and they are not usually a cause of concern. Some parents are then invited to volunteer their child for the experimental word-finding training based on these results. This does not necessarily mean that they have word-finding problems (e.g. for children acting as controls). Separate information sheets indicating what this involves will be given to parents.

Parents will also be given a link to a brief online questionnaire about the child's language history that they can fill out at their own time on their phone or computer. No identifiable information are collected and every parent will be assigned a number that matches the child's participation number. Only the researchers will have access to the questionnaire. There is no obligation on parents who have been contacted to have their children participate in the training.
