Prospective Person Memory: The Role of Self-Efficacy,Personal Interaction,and Multiple Images in Recognition of Wanted Persons

Prospective person memory refers to recognition of individuals one has been asked to be on the lookout for, such as wanted criminals or missing persons. Past field experiments have tended to find very low rates of identification. The present experiments examine whether multiple pictures, personal interaction, and increased self-efficacy would improve prospective person memory. Participants viewed a mock wanted person alert and were told that if they saw the person depicted in the alert they could win a cash prize. The alert either showed a single picture of the target person or multiple pictures. The target individual then showed up at the dining hall participants routinely had lunch. Some participants had peronal interaction with the target and some participants were led to believe that the likelihood of encounter was quite high. Despite these manipulations, only a small number of participants reported seeing the target individual.     

A Test of Sex Estimation in Subadults Using the Elevation of the Auricular Surface from Four Samples of Known Age and Sex

Biological sex is foundational to the work of forensic anthropologists and bioarcheologists. The lack of reliable biological sex estimation methods for subadults has, thus, greatly limited forensic and bioarcheological analyses. Auricular surface elevation showed promise as a subadult sex estimation method in previous studies. This study examined two auricular surface elevation evaluation methods on four subadult samples of known age, sex, and ancestry. Samples were scored as “male,” “female,” or “indeterminate” and results were examined with chi‐square analysis. No consistent sex estimation pattern, accuracy, or predictive value was produced between samples. Only one test was significant using Fisher's exact test analysis (FET = 7.501, p < 0.022): the composite approach on the Hamann‐Todd sample. While age, sample size, or developmental factors may play a role in these results, clearly sample variation does as well. This study found auricular surface elevation was not a useful subadult sex estimation method.     

Metric Assessment of the Pubic Bone Using Known and Novel Data Points for Sex Estimation,

Biological sex estimation of skeletal remains is essential in forensic and archaeological analyses. Anthropologists most often use the pelvis, which is the most sexually dimorphic element both morphologically and metrically. While nonmetric pubic bone features have been studied extensively, few metric studies have examined this individual bone for dimorphism. For this study, three observers examined three previously identified and ten novel measurements of the pubic body on a modern sample of isolated pubic bones from the Maricopa County Forensic Science Center (FSC), in Phoenix, Arizona (n = 400). A relationship between pubic body measurements and biological sex was demonstrated, with significant correlations. Discriminant function analyses found that five measurements, four of which were novel, discriminated between males (89%) and females (86%). Observer experience level did not significantly impact the results. These five measurements were reliable and show promise for inclusion in metric methods for assessment of sex.
