Cognitive Science and its Discontents

Optimality and some of its discontents: successes and shortcomings of existing models for binary decisions.

We review how leaky competing accumulators (LCAs) can be used to model decision making in two-alternative, forced-choice tasks, and we show how they reduce to drift diffusion (DD) processes in special cases. As continuum limits of the sequential probability ratio test, DD processes are optimal in producing decisions of specified accuracy in the shortest possible time. Furthermore, the DD model ...

Quasiregularity and Its Discontents: The Legacy of the Past Tense Debate

Rumelhart and McClelland's chapter about learning the past tense created a degree of controversy extraordinary even in the adversarial culture of modern science. It also stimulated a vast amount of research that advanced the understanding of the past tense, inflectional morphology in English and other languages, the nature of linguistic representations, relations between language and other phen...

Anthropomorphism and its Discontents

The usefulness of an approach in science is a difficult beast to capture. Attempts to quantify the fertility of anthropomorphism can quickly degenerate into something akin to a scientific beauty contest (at worst) or a matter of counting publications or citations of protagonists (at best). Blumberg asks “whether individuals who explicitly engage in anthropomorphism have a track record of scient...

Assimilation and its discontents: between rhetoric and reality.

"It is in [the] conceptual interstices between theory, rhetoric, and reality that paradoxes (or at least what may appear as paradoxes) emerge. By focusing on paradoxes--on evidence that contradicts orthodox expectations and points instead to assimilation's discontents--the aim of this article is to test empirically the conception of assimilation as a linear process leading to improvements in im...
