High electronic name agreement of 70 pictures in normative study of 5,290 Czechs for easy multicultural replication

The aim of this normative study was to verify recognition and name agreement of 70 black and white line pictures on a large Czech population sample using an electronic form. The set of pictures was selected based on previous research showing preliminary evidence of high name agreement with one word only. The pictures were arrayed into an electronic form that was distributed via the internet and filled in by 6,055 participants across the whole country. The group for final evaluation comprised of 5,290 respondents (age range 11-90 years, average ± SD: 53 ± 15 years, 77% of women, years of completed education: range 8-28 years, 15 ± 3 years) from all regions. The average name agreement for all pictures was 98%. Name agreement in the majority of pictures was not influenced by gender, age, and education. The most useful 14 pictures are entirely independent of all sociodemographic factors and include table, scissors, bell, ski, crown, chimney, glasses, steering wheel, heart, chain, ladder, horseshoe, bone, and alarm clock. The presented set of pictures named by one word only can be used for diagnostic or therapeutic purposes. The pictures and the electronic form are freely available for replication in other languages at our website www.abadeco.cz.
