A true denial or a false confession? Assessing veracity of suspects' statements using MASAM and SVA

Previous research on statement analysis has mainly concerned accounts by witnesses and plaintiffs. In our studies we examined true and false statements as told by offenders. It was hypothesized that SVA and MASAM techniques would enhance the ability to discriminate between true and false offenders' statements. Truthful and deceptive statements (confessions and denials) were collected from Swedish and Polish criminal case files. In Experiment 1, Swedish law students (N = 39) were asked to assess the veracity of statements either after training in and usage of MASAM or without any training and using their own judgements. In Experiment 2, Polish psychology students (N = 36) assessed veracity after training in and usage of either MASAM or SVA or without prior training using their own judgements. The veracity assessments of participants who used MASAM and SVA were significantly more correct than the assessments of participants that used their own judgements. The highest accuracy rate was for true confessions using MASAM (77,53%) and the lowest accuracy rate was for false denials using MASAM (38,78%). Both total SVA and MASAM scores differentiated between lies and truths. The criteria most strongly associated with correct assessments were: logical structure, contextual embedding, self - depreciation, volume of statement, contextual setting and descriptions of relations. Results show, that SVA is a better lie detection tool, than MASAM and trained coders are better at distinguishing between truths and lies than lay evaluators. The results are discussed in relation to statement analysis of offenders' accounts

Genome-wide analysis of multi-ancestry cohorts identifies new loci influencing intraocular pressure and susceptibility to glaucoma

Elevated intraocular pressure (IOP) is an important risk factor in developing glaucoma, and variability in IOP might herald glaucomatous development or progression. We report the results of a genome-wide association study meta-analysis of 18 population cohorts from the International Glaucoma Genetics Consortium (IGGC), comprising 35,296 multi-ancestry participants for IOP. We confirm genetic association of known loci for IOP and primary open-angle glaucoma (POAG) and identify four new IOP-associated loci located on chromosome 3q25.31 within the FNDC3B gene (P = 4.19 × 10 '8 for rs6445055), two on chromosome 9 (P = 2.80 × 10 '11 for rs2472493 near ABCA1 and P = 6.39 × 10 '11 for rs8176693 within ABO) and one on chromosome 11p11.2 (best P = 1.04 × 10 '11 for rs747782). Separate meta-analyses of 4 independent POAG cohorts, totaling 4,284 cases and 95,560 controls, showed that 3 of these loci for IOP were also associated with POAG
