“…Participants saw one version of the posters that either said that each of the wanted persons were wanted for committing armed grocery store robberies (i.e., accurate context expectations) or armed bank robberies (i.e., inaccurate context expectations). Each poster was displayed by itself for 15 s. We chose this presentation duration because Lampinen, Peters, and Gier () found that people spent approximately 13 s looking at missing child posters.…”

Prospective person memory refers to the task of being on the lookout for a missing or wanted person. In both laboratory and field-based tasks, prospective person memory performance has been poor. In the current study, we examined two factors that could be manipulated in the real world to increase successful recovery of missing or wanted persons: expectations of encounter and the cost of reporting wanted persons. Participants completed a computer task that simulated normal day-to-day tasks (i.e.., grocery shopping) while looking for four "wanted" persons.Participants who were given accurate context expectations made more accurate sightings and more inaccurate sightings than participants who were given inaccurate context expectations. The cost of reporting a sighting did not affect sighting rates.These findings indicate that people are more likely to notice a wanted person in their environment when they expect to encounter the wanted person in that environment.

“…Thus, the number of qualified people can be highly limited. Also, it is often ineffective to just rely on people's memory to find the child [31,32]. It might be difficult to obtain sufficient information to locate the child quickly.…”

Finding a missing child is an important problem concerning not only parents but also our society. It is essential and natural to use serendipitous clues from neighbors for finding a missing child. In this paper, we explore a new architecture of crowd collaboration to expedite this missioncritical process and propose a crowd-sourced collaborative mobile application, CoSMiC. It helps parents find their missing child quickly on the spot before he or she completely disappears. A key idea lies in constructing the location history of a child via crowd participation, thereby leading parents to their child easily and quickly. We implement a prototype application and conduct extensive user studies to assess the design of the application and investigate its potential for practical use.

“…Similarly, Lampinen et al (2012b) randomly assigned 50 American university student participants to observe four mock missing children appeals or 12 mock missing children appeals displayed on a large board (Lampinen et al 2012a, b). Participants were able to spend as much or as little time observing the appeals (Lampinen et al 2012a, b).…”

“…Hence, identification ability may be influenced by the time available to encode the information. In relation to missing children appeals, Lampinen et al (2012b) argue that if an individual is only able, or willing, to give a limited amount of time to an item, then an increase in the amount of information required to be encoded would result in less time available per item. Thus, the ability to encode the information successfully would significantly reduce.…”

“…Despite its importance and wide use, the research literature exploring the effectiveness of missing children appeals in recognising children is limited (Drivsholm et al 2017;Lampinen and Moore 2016;Lampinen & Sweeney, 2014). Moreover, it is suggested that individuals are generally quite poor at recognising unfamiliar faces (Davis and Valentine 2009;Burton 2006, 2008), especially when their attention is elsewhere (Lampinen et al 2012b;Miles 2005;Nobel and Shiffrin 2001). Therefore, the current study sought to fill this gap in our understanding by aiming to explore the effectiveness of missing children photograph appeals on the ability to accurately identify the child from a sequential lineup.…”

The study objectives were (1) to determine if there were any associations between the time spent observing fictional appeals and identification accuracy, (2) to establish if the number of missing children photographs observed influences identification accuracy and (3) to determine whether the number of missing children appeals observed influences identification accuracy following a short 3-day delay. A two-stage approach was utilised. Two hundred and forty-two participants observed one, four or eight mock missing children photographs followed by a short word memory distraction task and a target present line-up identification task. The second stage comprised of another target present line-up identification task presented after a short 3-day delay. One-way between-group ANOVAs indicate that observing one missing child photograph has significantly greater overall identification accuracy and lower identification error than viewing four or eight photographs immediately after observing the appeal and following a 3-day delay. Additional analyses found that the identification accuracy was significantly higher immediately after observation compared with the identification accuracy following a 3-day delay. The findings demonstrate the necessity for improving missing children appeals. Due to the exploratory nature of the study, additional research is required to explore these factors further. Keywords Child rescue alerts. Missing children. Missing persons. Publicity appeals. Recall accuracy An estimated 340,000 missing persons incidents are created each year within the UK, equal to one report every 90 seconds (Missing People 2018; National Crime Agency [NCA] 2017). Of these, approximately 60% relates to missing children although this is likely to be a significant underestimation (Hayden and Shalev-Greene 2016; Hill et al. 2016; Kiepal et al. 2012; Shalev et al. 2009). A common approach in this situation is for the police, family, friends, and charities to release a photograph of the missing children through the media in the hope that the public can help identify and locate the missing child (Lampinen et al. 2009; Lampinen et al. 2012a; Sweeney and Lampinen 2012). The use of the media is a vital resource for the police as it allows the photograph of the missing child to be viewed by a limitless number of individuals in a very short period of time (Fyfe et al. 2014; Taylor et al. 2013).
