Hypotheses

Hypothesis 1

We hypothesize that:

  • H0: There are no group differences in procrastination scores between cognitive groups (normative cognitive function; MCI; Dementia).
  • H1: There are group differences in procrastination scores between cognitive groups (normative cognitive function; MCI; Dementia)

Hypothesis 2

We hypothesize that:

  • H0: There is no association between procrastination and cognitive decline transitions
  • H1: Higher scores on a measure of procrastination are associated with:
    • Increased risk of transitioning from normative cognitive function to MCI / dementia \((\beta = x, p < .05)\)
    • Increased risk of transitioning from MCI to Dementia \((\beta = y, p < .05)\)

In order to test our hypotheses we will be using both a non-parametric ANOVA and a post-hoc test to compare procrastination scores between cognitive groups, and a discrete time Markov Model to assess the association between procrastination and cognitive decline transitions.
