Imagination allows us to escape our current time, place, or perspective in favor of an alternative context, whether that may be fanciful or mundane. So imagination is a mechanism for specifying and maintaining a context that differs from our more...

While the "modal model of memory" is still widely taught and accepted as a general theory, an enormous amount of recent research has focused on how short-term memory enables higher cognitive processes like those involved in planning, goals, and executive...

The capacity to use and manipulate symbols has been heralded as a uniquely human capacity (although we know at least a few cases where that seems untrue). The cognitive processes involved in symbol use have proven difficult to understand, perhaps...

Many will agree that algebra is difficult to learn - it involves planning, problem-solving, the manipulation of symbols, and the application of abstract rules. Although it's tempting to imagine a specialized region of the brain for each of these processes,...

The analytic depth of cognitive neuroscience is, in many ways, a curse. Those aspects of high-level cognition most relevant to real-world applications are the least understood at a neurobiological level, and those mechanisms that are well-understood neurobiologically are too simple...

It could be argued that any single level of scientific analysis is at once too simple (since there are always important emergent phenomena at higher levels) and also too complex (poorly-understood phenomena inevitably lurk at lower levels). If I wanted...

Theories with the fewest assumptions are often preferred to those positing more, a heuristic often called "Occam's razor." This kind of argument has been used on both sides of the creationism vs. evolution debate (is natural selection or divine creation...
