Soberanía, representación e independencia en Caracas, 1808-1811 (Estudios)

El artículo analiza el impacto que la crisis política de la monarquía española suscitó en Caracas, en donde tuvo lugar un intenso debate. En noviembre de 1808 se intentó erigir una junta, sin éxito. El 19 de abril de 1810 se constituyó la Junta Conservadora de los Derechos del Rey Fernando VII y, finalmente, el 5 de julio de 1811 se declaró la Independencia. El artículo analiza el contenido del debate acerca del ejercicio de la soberanía, así como la manera en que organizaron la representación política quienes tuvieron a su cargo la conducción de este proceso histórico, desde el inicio del movimiento juntista hasta la declaración de la indepedencia.

Working memory and working attention: What could possibly evolve?

The concept of “working” memory is traceable back to nineteenth century theorists (Baldwin, 1894; James 1890) but the term itself was not used until the mid-twentieth century (Miller, Galanter & Pribram, 1960). A variety of different explanatory constructs have since evolved which all make use of the working memory label (Miyake & Shah, 1999). This history is briefly reviewed and alternative formulations of working memory (as language-processor, executive attention, and global workspace) are considered as potential mechanisms for cognitive change within and between individuals and between species. A means, derived from the literature on human problem-solving (Newell & Simon, 1972), of tracing memory and computational demands across a single task is described and applied to two specific examples of tool-use by chimpanzees and early hominids. The examples show how specific proposals for necessary and/or sufficient computational and memory requirements can be more rigorously assessed on a task by task basis. General difficulties in connecting cognitive theories (arising from the observed capabilities of individuals deprived of material support) with archaeological data (primarily remnants of material culture) are discussed.
