“…For one thing, there are substantial errors in the reports of the times at which stimuli are presented and keys are pressed (e.g., Danquah et al, 2008;McCloskey et al, 1983). Although people might be more accurate about reporting their own internal processes than they are about reporting such externally observable events, there is certainly no guarantee that they are.…”

“…This clock-based measurement of subjective times is not without critics, of course. Some have argued that problems with the clock itself are partly responsible for inaccuracies of stimulus and key press time reports (e.g., Danquah et al, 2008;Joordens et al, 2002; but see Joordens, Spalek, Razmy, & Van Duijn, 2004). Others have suggested that the clock-based measurement process may alter the neural activity associated with very intentions and actions that it is intended to measure (e.g., Lau, Rogers, & Passingham, 2006).…”

“…Accordingly, many studies have examined how accurately people can report the times of stimulus presentations and the times of their overt responses (e.g., Danquah, Farrell, & O'Boyle, 2008;Joordens, Van Duijn, & Spalek, 2002;McCloskey, Colebatch, Potter, & Burke, 1983;Pockett & Miller, 2007), because the times of these physical events can be determined with great precision. In contrast, a person's decision to act is a mental event, so there is no decisive objective marker of when that event took place.…”

“…As mentioned, the accuracy of Libet's method for measuring the onset times of W has been questioned and criticized many times (see Glynn 1990, Gomes 2002, Joordens et al 2002, and Danquah et al 2007, for instance). This issue has been addressed in a more recent experiment conducted by John-Dylan Haynes and colleagues (Soon et al 2008).…”

The neuroscientific study of free will: A diagnosis of the controversy

Benjamin Libet's work paved the way for the neuroscientific study of free will.Other scientists have praised this research as groundbreaking. In philosophy, the reception has been more negative, often even dismissive. First, I will propose a diagnosis of this striking discrepancy. I will suggest that the experiments seem irrelevant, from the perspective of philosophy, due to the way in which they operationalize free will. In particular, I will argue that this operational definition does not capture free will properly and that it is based on a false dichotomy between internal and external causes. However, I will also suggest that this problem could be overcome, as there are no obvious obstacles to an operationalization of free will that is in accord with the philosophical conception of free will.

“…Una de las críticas que se ha hecho ha sido la amplia variabilidad en las diferencias entre distintos sujetos respecto al juicio emitido sobre el tiempo de ocurrencia de eventos internos 28 , dos de las mediciones cruciales en el experimento de Libet. Si la diferencia es muy grande entre un sujeto y otro, habría que replantearse la validez de este tipo de mediciones y los correlatos que pueden desprenderse de ahí (ya sea entre sí, o en relación con las mediciones objetivas realizadas por el equipo de Libet).…”

ResumenUna idea fundamental para sostener conceptos éticos fundamentales, tales como el de autonomía, responsabilidad etc., lo es la "libertad". La aporía determinismo/libertad ha estado presente en la filosofía desde el mundo antiguo. Sin embargo, tras el desarrollo de las neurociencias, se ha planteado que la libertad es una mera ilusión y que los seres humanos estamos determinados neurobiológicamente en nuestro actuar. Este trabajo presenta los trabajos pioneros de Benjamín Libet sobre este tema (una aproximación que utilizó electroencefalografía y electromiografía), a la vez que realiza una crítica sobre las interpretaciones del propio Libet. Palabras-clave: Bioética. Neurociencias. Filosofía. Resumo Liberdade e ética: o trabalho de Benjamin LibetUma ideia fundamental para sustentar conceitos éticos fundamentais, tais como autonomia, responsabilidade, etc., é a "liberdade".

Palavras-chave: Bioética. Neurociências. Filosofia. Abstract Freedom and ethics: Benjamin Libet's workA fundamental idea to sustain basic ethical concepts such as autonomy, responsibility, etc., is "liberty". The determinism/freedom aporia has been present in philosophical tradition since ancient world. However, after the development of neuroscience, it has been argued that freedom is merely an illusion and human beings are neurobiologically determined in our actions. This paper presents the pioneering work of Benjamin Libet on this subject (an approach that used electroencephalography and electromyography), also a critique on Libet interpretations of his results.
