IMPLY

IMPLY: A program for the construction of deduced intervals on secondary contrasts from confidence intervals on primary contrasts - Kevin D. Bird and Emily M. Bird

IMPLY produces deduced intervals (DIs) on any number of secondary contrasts from a set of confidence intervals (CIs) on (J - 1) linearly independent primary contrasts on J means (Bird, 2011). IMPLY also provides the coefficient vectors used to express the secondary contrasts as linear combinations of the primary contrasts.

Before running IMPLY, you will need to have obtained the lower and upper CI limits for each primary contrast from a statistical package or a program such as PSY. Click here to download PSY. IMPLY is written in the freely available programming language R, which you will need to have installed on your computer. Click here to download R.

    My research program addresses the development of memory and emotion during infancy and early childhood and takes a developmental cognitive neuroscience approach. I am particularly interested in the development of relational memory and the role it might play in representational flexibility. My recent work has looked at age-related changes in episodic memory and future thinking during early childhood and the development of rapid facial mimicry in infancy.
