Simulate the C(ues) T(endency) A(ction) model of motivation

Description

Dynamic motivational models such as the Dynamics of Action (Atkinson and Birch, 1970, Revelle, 1986) may be reparameterized as a simple pair of differential (matrix) equations (Revelle, 1986, 2008). This function simulates the dynamic aspects of the CTA.

Usage

cta(n = 3, t = 5000, cues = NULL, act = NULL, inhibit = NULL, consume = NULL, ten = NULL, type = "both", fast = 2, compare = FALSE)

Arguments

n number of actions to simuate
t length of time to simulate
cues a vector of cue strengths
act matrix of associations between cues and action tendencies
inhibit inhibition matrix
consume Consummation matrix
ten Initial values of action tendencies
type show actions, tendencies, both, or state diagrams
fast display every fast time (skips
compare Compare?

Details

A very thorough discussion of the CTA model is available from Revelle (2008).

Value

graphical output

cues echo back the cue input
inhibition echo back the inhibitory matrix
time time spent in each activity
frequency Frequency of each activity
ten final tension values
act final action values
