Abstract

In conjunction with Sophie Whitfield and Shirley Coleman ISRU, Newcastle University

The purpose of this talk is to explain the analysis of data associated with Activities of Daily Living (ADLs) and theorise about what is physically happening on the basis of the results. The ADLs are initially ordered sequentially using Mokken scaling. Previous work has validated this ordering method. An initial analysis of a number of individuals time to lose ADLs is compared to the overlapping of four harmonic functions which shows a reasonable fit. After ordering the times to lose an ADL, it was found that the modal time occurs near or at a Fibonacci number, this number decreasing as the ADLs become less complex. This observation is validated by re-analysing the data using a Pareto distribution and analysing the harmonic means. On analysing the modes in more detail, it is possible to identify the same bodily movement used within different ADLs. The time of loss of this movement is plotted against the time to gain this movement during child development and a linear relationship results. These analyses are the first data validation of Katz’s observations in 1963 of this relationship.
