30 ENCOUNTER: <strong>Education</strong> for Mean<strong>in</strong>g and Social Justice<br />

Cognitive Development<br />

Confident she had unpacked the self-organiz<strong>in</strong>g<br />

nature of motor development, Thelen turned her attention<br />

to the cognitive doma<strong>in</strong>. She began by revisit<strong>in</strong>g<br />

the work of certa<strong>in</strong> explorers from the previous<br />

generation of developmental psychologists — Jean<br />

Piaget, Kurt Lew<strong>in</strong>, and Eleanor and James Gibson,<br />

among others — who had already begun to break<br />

away from the old-paradigm view that <strong>in</strong>telligence is<br />

exclusively a mental th<strong>in</strong>g and that learn<strong>in</strong>g is the passive<br />

absorption and storage of <strong>in</strong>formation. Piaget,<br />

Lew<strong>in</strong>, and the Gibsons were all holistic th<strong>in</strong>kers who<br />

viewed cognitive development as an active and <strong>in</strong>teractive<br />

construction process that <strong>in</strong>volves the body as<br />

well as the m<strong>in</strong>d. For them, development became the<br />

study of all of the means by which children learn to<br />

adapt successfully to the changes and challenges <strong>in</strong><br />

their respective environments.<br />

Thelen proceeded to weave <strong>in</strong>to this new orientation<br />

the recent neuroscientific discoveries that were<br />

unavailable to Piaget and the others. She drew heavily<br />

upon the research of the aforementioned Gerald<br />

Edelman, one of whose pr<strong>in</strong>cipal areas of <strong>in</strong>vestigation<br />

is the neural basis of cognitive development, and<br />

beyond that, of consciousness as a whole. Like the<br />

Gibsons before him, Edelman believes the process beg<strong>in</strong>s<br />

with perception. Whenever <strong>in</strong>fants see, hear,<br />

smell, or touch someth<strong>in</strong>g, their bra<strong>in</strong>s construct actual<br />

neural maps that emerge spontaneously from the<br />

chaotic <strong>in</strong>teraction of large groups of neurons <strong>in</strong> the<br />

bra<strong>in</strong>. There is no localized control center responsible<br />

for the mapp<strong>in</strong>g; rather the neural patterns that underlie<br />

perception are self-organiz<strong>in</strong>g. Moreover, the<br />

patterns are “plastic,” mean<strong>in</strong>g that their shape<br />

readily alters <strong>in</strong> synch with shifts <strong>in</strong> experience. Then,<br />

over time, the maps overlap and reassemble as babies<br />

beg<strong>in</strong> to sort their perceptions <strong>in</strong>to the categories that<br />

will become the basis of their concrete knowledge<br />

about the world. Categorization, too, is a self-organiz<strong>in</strong>g<br />

process (Thelen & Smith 1994, 136).<br />

Edelman’s mapp<strong>in</strong>g theory stands <strong>in</strong> stark contrast<br />

to the old-paradigm assumption that the categories<br />

which give order to our th<strong>in</strong>k<strong>in</strong>g — space,<br />

time, shape, color, causation, and so on — are fixed<br />

and have an <strong>in</strong>dependent existence like Newton’s<br />

laws. Accord<strong>in</strong>g to Edelman, there are no predeterm<strong>in</strong>ed<br />

categories because they are constantly chang<strong>in</strong>g<br />

and comb<strong>in</strong><strong>in</strong>g <strong>in</strong> orig<strong>in</strong>al ways depend<strong>in</strong>g on<br />

the context, history, and current state of the<br />

perceiver. Aga<strong>in</strong>, broad evolutionary parameters do<br />

exist; however, each <strong>in</strong>dividual m<strong>in</strong>d is uniquely<br />

shaped by experience and the dynamics of self-organization.<br />

Thelen, as did Piaget, ref<strong>in</strong>ed her <strong>in</strong>sights <strong>in</strong>to the<br />

basic nature of cognition by zoom<strong>in</strong>g <strong>in</strong> on the world<br />

of <strong>in</strong>fants. She started out by <strong>in</strong>vestigat<strong>in</strong>g babies’<br />

early efforts to reach and search because these<br />

goal-oriented behaviors play a fundamental role <strong>in</strong><br />

all subsequent perceptual-motor and rational-symbolic<br />

learn<strong>in</strong>g. Like Piaget — and <strong>in</strong> some <strong>in</strong>stances<br />

repeat<strong>in</strong>g certa<strong>in</strong> of his iconic experiments — she<br />

was able to show how cognitive development<br />

self-organizes <strong>in</strong> exactly the same manner as<br />

sensorimotor development, driven by a child’s <strong>in</strong>tr<strong>in</strong>sic<br />

motivation to explore and seek out novel and<br />

challeng<strong>in</strong>g experiences. Interest<strong>in</strong>gly, Piaget (1952,<br />

407-410) valued kids’ self-<strong>in</strong>itiated, self-directed discoveries<br />

so highly that he sometimes referred to<br />

them by the French word aliment, mean<strong>in</strong>g food.<br />

Along the way, Thelen was able to root out the<br />

Newtonian vestiges <strong>in</strong> Piaget’s th<strong>in</strong>k<strong>in</strong>g, the most<br />

prom<strong>in</strong>ent among them the idea that there is a universal<br />

template for cognitive development, which<br />

occurs <strong>in</strong> an orderly succession of stages. Her meticulous,<br />

high-magnification observations clearly<br />

showed that because every child’s <strong>in</strong>ner make-up<br />

and outer circumstances are unique, and because development<br />

emerges out of the dynamic <strong>in</strong>teraction<br />

between the two, the developmental process isn’t<br />

uniform at all. To use Thelen’s metaphor, development<br />

is “not a march<strong>in</strong>g band; it’s a teem<strong>in</strong>g mob.”<br />

(Thelen & Smith 1994, 21-22).<br />

Thanks to Esther Thelen and her associates, we are<br />

presented with an entirely new model whereby development<br />

self-assembles <strong>in</strong> context and <strong>in</strong> the moment,<br />

with the direction always com<strong>in</strong>g from with<strong>in</strong>. Or <strong>in</strong><br />

her words, “Development can happen <strong>in</strong> an organized<br />

way all on its own with neither an external<br />

teacher nor a bluepr<strong>in</strong>t for the developmental outcome.”<br />

(Thelen & Smith 1994, 170). Beg<strong>in</strong>n<strong>in</strong>g from<br />

the moment we are born it is a cycle of challenge, exploration,<br />

discovery, and new challenge that cont<strong>in</strong>ues<br />

until the day we die (Thelen & Smith 1994,<br />

323-325). And aga<strong>in</strong>, the process is self-motivated and
