<b>written in LISP.</b>
 
<b>model of human cognition; </b> derived from cog psych and brain imaging.
 
does Tower of Hanoi, memory for text or list of words, language comprehension, aircraft control.
 
<b>Running a model automatically produces a step-by-step simulation of human behavior which specifies each individual cognitive operation (i.e., memory encoding and retrieval, visual and auditory encoding, motor programming and execution, mental imagery manipulation). Each step is associated with quantitative predictions of latencies and accuracies. The model can be tested by comparing its results with the data collected in behavioral experiments.</b>
 
 
In recent years, ACT-R has also been extended to make <b>quantitative predictions of patterns of activation in the brain</b>, as detected in experiments with <a title="FMRI" class="mw-redirect" href="/wiki/FMRI">fMRI</a>. In particular, ACT-R has been augmented to predict the shape and time-course of the <a title="Blood-oxygen-level dependent" class="mw-redirect" href="/wiki/Blood-oxygen-level_dependent">BOLD</a> response of several brain areas, including the hand and mouth areas in the <a title="Motor cortex" href="/wiki/Motor_cortex">motor cortex</a>, the left <a title="Prefrontal cortex" href="/wiki/Prefrontal_cortex">prefrontal cortex</a>, the anterior <a title="Cingulate cortex" href="/wiki/Cingulate_cortex">cingulate cortex</a>, and the <a title="Basal ganglia" href="/wiki/Basal_ganglia">basal ganglia</a>.
