Component Numeracy Skills And Decision Making, Saima Ghazal

Dissertations, Master's Theses and Master's Reports - Open

Numeracy—i.e., one’s practical understanding of mathematics in context—is one of the strongest predictors of people’s general decision making skill, independent of other cognitive abilities (e.g., intelligence, working memory, attentional control). Despite notable scientific progress on the nature of numeracy and decision making, the cognitive and decision sciences have yet to investigate individual differences in numeracy components (e.g., algebra versus probability). In this dissertation, I report on my efforts to develop new measurement technology and quantitative models of cognitive and decision skills. Analyses include the first known investigations of the relations between the major adult component numeracy skills and general decision …
