cta {psych} | R Documentation |
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.
cta(n = 3, t = 5000, cues = NULL, act = NULL, inhibit = NULL, consume = NULL, ten = NULL, type = "both", fast = 2, compare = FALSE)
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? |
A very thorough discussion of the CTA model is available from Revelle (2008).
