Evidence for a dichotomy between the planning of an action and its on-line control in
humans is reviewed. This evidence suggests that planning and control each serve a …

This paper aims to review a long-term research project exploring the chimpanzee mind
within historical and ecological contexts. The Ai project began in 1978 and was directly …

Miller (1956) summarized evidence that people can remember about seven chunks in short-
term memory (STM) tasks. However, that number was meant more as a rough estimate and …

Commentators expressed a wide variety of views on whether there is a basic capacity limit of
3 to 5 chunks and, among those who believe in it, about why it occurs. In this response, I …

Cowan's revisiting of the magic number is very timely and the case he makes for a more
moderate number than seven is persuasive. It is also appropriate to frame his case within a …

In this study, we compared the performances on an enumeration task (numerical labeling
task) of 1 chimpanzee (Pan troglodytes) and 4 humans. In this task, two types of trials, with …

It is our contention that the concept of planning in Glover's model is too broadly defined,
encompassing both action/goal selection and the programming of the constituent …

The aim of our commentary is to strengthen Cowan's proposal for an inherent capacity
limitation in STM by suggesting a neurobiological mechanism based on competitive …

Cowan assumes that chunk-based capacity limits are synonymous with the essence of a
“specialized STM mechanism.” In a single experiment, we measured the capacity, or span …

In the current study, we examined the planning abilities of rhesus monkeys (Macaca mulatta)
by training them on a five-item list composed of coloured photographs and then testing them …
