discrimination and perception (da capo, in the Italian sense)

"Keith Hughes" wrote in message ... snip Real scientists investigate observed, or observable (i.e. inferred or extrapolated from existing predicates, though not directly observed) phenomena. You really need to get a grip on the difference between theory and speculation. A "what if" without any experiential underpinnings is speculation, and while that speculation may be of interest to some specific individual, or group, scientific investigation of such is unwarranted. Keith, when dealing with music and a judgement as to how realistically a piece of equipment in a system reproduces it in approximation of the real thing, the judgement is of necessity subjective. Agreed. Their is no such thing as "objective" music. Actually, there clearly is "objective" music, in that it physically exists, and can be objectively observed and measured. If you mean that music has no *intrinsic* aesthetic quality outside of the context of an individuals' subjective appreciation of such, then I would agree. So while experimentation of necessity must find a way to "objectify" the subjective, using the tools of psychology and the social sciences, it is not essential to do so to form the contextual hypothesis. The point, Harry, is that an hypothesis requires *some* evidence, though that evidence need not be sufficient for formulation of a theory. Psychological and behavioral sciences are predicated on observations, just like the 'hard' sciences are. That these are externally observable manifestations of internal, subjective, processes is irrelevant. There are still objective data upon which investigations are then based, or directed. When a postulate is posed, sans evidence or observation, that is speculation. Nothing inherently wrong with speculation, we all do it, but let's call it what it is. In fact, such "inner examination" has been the wellspring of much progress both in psychology and in the social sciences. Well...that could be debated as well :-) However, when performing such "inner examination" one must always be cognizant that one is a) using a tool to measure itself (i.e. using the mind to examine itself) which has many rather obvious opportunities for error, and b) to the extent that the results of such examinations *are* accurate, they are not tethered to objective reality (and therefore useless scientifically) unless the external stimulus can be defined and measured. Full characterization of an independent variable is of no utility when the concomitant dependent variables are unknown (or unknowable). A major difference here, it seems to me, is between you engineers Pardon me, but I'm not an engineer. I'm a cellular biologist by training, although I did take an AA in electronics some years after university. who are comfortable treating the problem as one of traditional sound-based auditory measurement, and others of us who see the problem as more complex and when it comes to musical synthesis by the brain, as more contextual in nature. I think everyone here agrees with that Harry. You are, however, conflating two rather disparate, and qualitatively distinct processes. Clearly the appreciation of music is affected by context (and of course, let us not forget that visual stimulation is part of that context). But just as clearly, the only audible contextual component is what is 'measured' by the ears. If a stimulus does not cause an auditory response, there is nothing for the brain to 'synthesize' with (at least not based on auditory information). Nobody would dispute that eventually any hypothesis as argued here would have to be reduced to factual evidence. But to do so requires funding, time, and an organizational resource devoted to testing. That is beyond the ken of we amateurs, who gather here because of our hobby. But it doesn't make the speculation invalid. No it doesn't, Harry. However, let's recognize that it *is* speculation, and however interesting that might be to hobbyists like us, such speculations are not the interest of funded researchers, and never will be. And that was the basis of my post, i.e. scientists are *not* typically interested in speculation, there are far too many observations, for which the underlying mechanisms are not characterized, for time and money to be spent on researching speculations.

The sad thing is that no one has, with any real scientific insight, responded to the issues I raised on this group. Instead, the predominant response has been an obstructionist, defensive position like yours. You can't say I wasn't patient. Mark |

Mark Well, Mark, we gave you several reasons why no one has any scientific interest in pursuing your question further. You just prefer to interpret that lack of interest as something defensive and obstructionist from us. But hey, you can always continue that with people like Michael Mossey, right? |

Mark DeBellis wrote: Chung wrote: Harry Lavo wrote: Mark, you should realize by now that you are not engaging scientists in scientific speculation. And the reason is that nothing that Mark has said so far on this subject is of the remotest scientific interest to any scientist. Let me get this straight. What I've said is, if context affects perception, then it sure doesn't look to me like DBT's are going to be a good way to find out how it does. So, why would they be? DBT's are for measuring audible differences. So many "contexts" are non-sonic in nature. Therefore it does not interest me to discuss how DBT's are not good for controlling contexts. For instance, the appearance of a piece of audio gear affects perception. DBT's clearly are not a good way to find out how appearances actually affect perception. Which has nothing to do with what I've been asking: if you go back and look at my example, it's obviously the sonic context that I'm talking about. Of course, there is a strain of thought on this newsgroup that holds that "Sighted testing is unreliable" is an adequate response to *any* question or claim, no matter how irrelevant it may be in fact. And you, Chung -- a proponent of DBT's for determining significant sonic differences Actually, subtle differences... -- think it's an adequate response to this to say, basically, that the question doesn't interest you, and wouldn't interest any scientist, because I haven't defined the question well enough? The question you "defined" does not make sense to a scientist. Says you. The relevant science here is psychology, and the question is whether certain perceptual processes that take place over time are best measured by DBT's. So, for example, are DBT's well suited to measure a difference in perceived loudness between two events, if the sonic contexts of those events have an influence on perceived loudness? And are DBT's well suited to help us discover whether, and how, sonic context affects perceived loudness? I explained what I thought the problems we either the comparison is time-distal or it eliminates context, and some explanation would then be needed of why it is OK to eliminate context. Sorry if that doesn't "make sense" to you. But your insistence on measurement is misplaced. Specifying a method of measurement may be part of some scientifically rigorous *answer* to the question, but it's not a condition on the question itself; for the latter, what's required is *reference* to the process that, later on, gets measured. Otherwise, questions like "How do we measure X?" or "What is a correct definition of X?" can't even get off the ground. Mark |

Mark You said that we are taking an obstructionist/defensive position on your questions. I try hard to understand what you are saying in the above paragraph, and I still have no idea what you are talking about. If you want people to respond, you have to ask questions that can be understood. 1. What do you mean by perceived loudness? I know we can compare two sounds and come up with a qualititative response of which one *appears* to sound louder. Are you talking about which one of two sounds appear louder? How do we measure perceived loudness? 2. What exactly is sonic context? 3. How can you control sonic context? 4. Why would your questions be of interest to anyone? Let me try to ask a question using your particular style, and maybe you can see the pointlessness of this type of questions: Our mood seems to affect our perception. How can anything measure the effects of our moods on our perception? Is that an interesting question to scientists? |

For example, the scientists who test anti-depressants have not retreated from an attempt to quantify mood. Mike |
