Researchers investigated whether children who spent time alone during outdoor play had difficulty forming relationships with other children. Three early-years centres agreed to participate. Caregivers of 36 children aged four to five gave permission, and the children were given a simple explanation and asked whether they agreed to be watched. Centre staff selected children who regularly attended the morning sessions.

The researchers conducted an overt, naturalistic observation during six morning play periods at each centre. Every two minutes, an observer recorded whether each child was playing alone, alongside others without a shared activity, or in a shared activity. Playing alone was defined as using materials without exchanging words or objects with another child. Researchers also wrote brief notes about what happened before and after these episodes. Children could ask observers to stop recording them.

The researchers initially treated frequent solitary play as evidence of relationship difficulties. Staff members questioned this interpretation, explaining that some children chose to finish a drawing or examine objects alone before joining others. The researchers therefore reviewed their notes for instances of children entering shared activities. Two observers independently classified a selection of the same episodes, but differed over whether silently watching another child's activity counted as playing alone.

Nine children were recorded as playing alone during more than half of their observation periods. Seven of these children also initiated a shared activity on at least two occasions. Notes indicated that some solitary episodes occurred after disagreements, while others occurred when children were concentrating on an activity they had chosen. The researchers concluded that solitary play could have several meanings and should not automatically be treated as a relationship difficulty. However, their report recommended that centres monitor children who frequently played alone, without specifying how the observations should be used.

Researchers investigated whether the length of time adults had lived in a neighbourhood was associated with their sense of belonging. They distributed a questionnaire to every household on six streets in one town. One adult per household was invited to respond anonymously. Of 240 questionnaires distributed, 96 were returned. Respondents reported how long they had lived locally and whether they owned or rented their homes.

The questionnaire contained eight statements, each answered on a five-point scale from strongly disagree to strongly agree. Statements included 'I attend organised neighbourhood events', 'I know the names of people living nearby' and 'I would feel comfortable asking a neighbour for help'. Researchers combined these responses into a belonging score. They had developed the statements from their own experiences of neighbourhood life and checked with five colleagues that the wording was understandable.

An optional final question asked respondents to describe anything that made them feel connected to the neighbourhood. Some described attending events, while others mentioned familiar shopkeepers, exchanging greetings or helping neighbours without attending organised activities. Several recent residents said that evening events were difficult to attend because of work or caring responsibilities. The researchers read these comments after calculating the scores but did not revise the scoring system.

Respondents who had lived locally for more than ten years had higher average belonging scores than those who had arrived within the previous two years. Longer-term residents were also more likely to own their homes and be retired. Some recent residents described feeling strongly connected despite receiving low scores. The researchers concluded that living in a neighbourhood for longer strengthens belonging. They proposed using their questionnaire to compare neighbourhoods elsewhere, although they had not investigated whether its statements would capture belonging in those settings.

Researchers investigated whether feedback about mistakes improved learning of unfamiliar written symbols. Forty adult volunteers were recruited through a public library notice. Participants were randomly allocated to two groups of twenty in an independent-measures experiment. Before learning began, everyone completed a short symbol-matching task to check that they could distinguish the symbols visually.

All participants studied the same twelve symbols and their meanings for ten minutes. They then completed three practice rounds. After each response, one group saw the correct answer and the message 'Incorrect answers show you what to practise next' whenever they made a mistake. The other group saw only the correct answer. Correct responses received the same brief acknowledgement in both groups. The computer controlled presentation time, and all participants completed the task individually in the same room.

The researchers approached mistakes as gaps in knowledge and expected the additional message to direct attention towards material requiring further study. After practice, participants completed an immediate test and rated how useful they had found the feedback. They were also invited to explain their rating in writing. Some participants described mistakes as useful information, whereas others described making mistakes as embarrassing even though no one else saw their responses. Participants knew that the study compared feedback, but were not told the predicted outcome until debriefing.

The group receiving the additional message had a higher average immediate test score and rated the feedback as more useful. Written comments suggested that some participants became more willing to attempt uncertain answers; others reported feeling under pressure to improve. No later test was conducted. The researchers concluded that presenting mistakes as useful improves learning and recommended the message for classroom use. They did not investigate whether participants would respond similarly when classmates could see their mistakes or when performance contributed to a course grade.
