A demonstration sued with methods in which neural function is deliber of the clinical potential of this method comes fom a re ately perturbed.

Cognitive neurosci modeling and how it has ben used by cognitive neurosci ence is no exception. It is a feld that emerged in part entists, and we review a powerful analytical and modeling because of the invention of new methods, some of which tool—brain graph theory, which transforms neuroimag use advanced tools unavailable to scientists of previous ing data into models that elucidate the netork proper generations (se Chapter 1; Sejnowski & Churchland, ties of the human brain. In this chapter, we discuss how these methods cognitive neuroscience has depended on the clever ways work, what information can be derived fom them, and in which scientists have integrated paradigms across all their limitations. The chapter concludes other players in the neurosciences, fom neurologists with examples of this integration. Cognitive neuroscience is distinctive in the study of Behavioral Methods the brain and behavior, because it combines paradigms Cognitive neuroscience has ben informed by the prin developed in cognitive psychology with methods em ciples of cognitive psychology, the study of mental ployed to study brain structure and function. They also sek to identif the internal processing— Representations and the acquisition, storage, and use of information—that underlies this performance. A basic assumption of cogni Transformations tive psychology is that we do not directly perceive and Two key concepts underlie the cognitive approach: act in the world. Rather, our perceptions, thoughts, and actions depend on internal transformations or 1. Tese mental representations undergo nize it as something that we have experienced before and transformations. Cognitive psychologists design Mental Representations We usually take for granted experiments to test hypotheses about mental operations the idea that information processing depends on internal by adjusting what goes into the brain and then seing representations. Put more simply, information is input thinking of an image, a word description, or a math into the brain, something secret happens to it, and out ematical formula Cognitive psychologists are detectives of representing the “circular” or “spherical” concept trying to fgure out what those secrets are. The context would help dictate which representa ti edost’n rtaem ni awth rreod eht tlteser ni a rwdo tional format would be most useful. For example, if we rea, eht ylon pirmtoatn gihtn si ath het rifs nda satl wanted to show that the ball rolls down a hill, a pictorial telre eb tat het ghitr clepa. Now take another shot at it: Posner (1986) at the Universit of Oregon, provides a powerful demonstration that even with simple stimuli, Aoccdrnig to a rsehearcr at Cmabrigde Uinervtisy, the mind derives multiple representations (Figure 3. The rset can be a total both vowels, both consonants, or one vowel and one con mses and you can sitll raed it wouthit porbelm. The participant presses one buton if the leters is bcuseae the huamn mnid deos not raed ervey lteter are fom the same category, and the other buton if they by istlef, but the wrod as a wlohe. It is sur One version of this experiment includes fve condi prisingly easy to read the second passage, even though tions. In the physical-identit condition, the to leters are only a few words are correctly spelled. In the phonetic-identit condition, the and last leters of each word are in the correct position, to leters have the same identit, but one leter is a capi we can accurately infer the correct spelling, especially tal and the other is lowercase. Tere are to tpes of same when the surrounding context helps generate expecta category conditions, conditions in which the to leters tions for each word. In one, both help us discern the content of mental representations, leters are vowels; in the other, both leters are consonants. The dependent variable is the event be manipulating one variable and observing its effect on ing studied. It is what you (the researcher) the independent variable is displayed on the horizontal axis have changed. Finally, in the diferent-category condition, the to leters The results of Posner’s experiment suggest that we are fom diferent categories and can be either of the same derive multiple representations of stimuli. Note that the frst four con tation is based on the physical aspects of the stimulus. In ditions—physical identit, phonetic identit, and the to this experiment, it is a visually derived representation of same-category conditions—require the “same” response: the shape presented on the scren. A second representa On all thre tpes of trials, the correct response is that the tion corresponds to the leter’s identit. For example, we can recognize that Participants respond fastest to the physical-identit condi A, a, and a all represent the same leter. A third level of tion, next fastest to the phonetic-identit condition, and abstraction represents the category to which a leter be slowest to the same-category condition, especially when longs. At this level, the leters A and E activate our internal the to leters are both consonants. The defnition of “same” and “different” is manipulated across different blocks of the experiment. This relationship is the independent variable, the variable that the experimenter is manipulating. Did you register that last sentence, or did all By this logic, we infer that physical representations are the talk about garlic cause your atention to wander as activated frst, phonetic representations next, and cat you made plans for dinner As you may have experienced personally, experi ments like these elicit as many questions as answers.

Chrono Saul Sternberg (1975) introduced an experimental metric comes fom the Grek words chronos (“time”) and task that bears some similarit to the problem faced by metron (“measure”). In Sternberg’s task, however, is essential for cognitive psychologists because mental the job is not recalling items stored in memory, but rather events occur rapidly and efciently. If we consider only comparing sensory information with representations that whether a person is correct or incorrect on a task, we are active in memory. Ten a single leter is presented, and the participant must decide if this leter was part of the memorized set. The Internal Transformations The second critical no participant presses one buton to indicate that the target tion of cognitive psychology is that our mental repre was part of the memory set (“yes” response) and a sec sentations undergo transformations. For instance, the ond buton to indicate that the target was not part of the transformation of mental representations is obvious set (“no” response). Once again, the primary dependent when we consider how sensory signals are connected variable is reaction time. For example, a whif Sternberg postulated that, to respond on this task, the of garlic may transport you to your grandmother’s house participant must engage in four primary mental operations: or to a back alley in Palermo, Italy. The participant must identif the visible olfactory sensation has somehow ben transformed by target.

Speci cally skin care institute cheap eurax 20 gm line, the shallow notch at the wider distal end lends itself to acne cleanser purchase eurax 20 gm line this by the very shape and the manner of the 255 New Perspectives on the Beginnings of Music Fig acne and dairy cheap eurax 20gm with visa. The fanlike distal widening at the metaphysis forms a kind of natural mouthpiece and thus facilitates the embouchure acne and diet safe eurax 20gm. Such a manner of stimulating sound in a ute is also mentioned several times with other related archeological nds (Galin 1988), including an Upper Paleolithic nd from Pas du Miroir in France (Marshack 1990) where a mouthpiece is clearly visible on a beautifully made and preserved ute. Some authors reject the possibility of such a manner of playing because, in their opinion, the femur of a young cave bear is too wide at the metaphysis for it to be possible to close most of the bone with the lips and at the same time direct air at the cut edge (Horusitzky 1955). This is the main reason for instruments similar to this one being classi ed among trans verse utes. We demonstrated that it is possible to make sound on a bone ute in such a manner. The ute could be held against the lips in various ways (for a more exact description, see Kunej 1997). The bone wall by the distal shallow notch, with a thickness of around 2 to 3mm, had a sharp enough cut edge to enable a ne and pure sound, a fairly large tonal range, and the ability to produce overblowing. Even badly cleaned spongiosa on the fossil bone did not greatly hinder a fair range of tones; it was only more dif cult to achieve higher tones and prevent overblowing. With the reconstruction from fresh bone, badly removed spongiosa had signi cantly less in u ence, since it is more homogeneous and even fatty and was not explic itly porous as is fossil bone. Thus it was simpler to produce sound and to achieve higher tones and overblowing with the reconstruction from fresh bone than with fossil bone. This manner of stimulating sound seemed at rst more suitable from acoustic and ethnomusicological standpoints, and was therefore the most thoroughly tested. The basic pitch and overblowing to produce overtones could be executed on the open or closed ute, and with the closed ute occasionally even to the second overtone. In principle, our nd could also have been adapted into such an instrument if a short block (pple) had been set in the bone to shape the jet of air and direct it at the cut edge (gure 15. A block can also be provided by unremoved spongy bone in which a narrow incision is made (hori zontal hole) that directs the jet of air at the cut edge. Production of such mouthpieces seems more demanding, and our nd has no trace of such a mouthpiece or way of blowing, so a ute of this type was not acousti cally tested. Archeologists have classi ed a large number of bones with holes as transverse utes, a possibility suggested in our instrument by the one hole that at least theoretically enables stimulation of sound. The cut edge 257 New Perspectives on the Beginnings of Music is provided by the sharp edge of the hollowed-out hole on which we blow, and the instrument is thus held crosswise to the mouth (gure 15. It can often be found in the professional literature that such a method of blowing on an instrument is more recent than lengthwise production of sound. We could also stimulate sound with reconstructions in the manner of transverse utes. This was especially possible where the bone wall was thin, in which any kind of hole easily suf ced as a sharp cut edge. With thicker walls, it was necessary to make the hole more carefully in order to create a sharp, rectangular edge. We were able to achieve individual tones only with such a method of blowing, some fairly indis tinct and dif cult to produce. The basic tone of a ute depends on its length and is fairly simple to calculate for cylindrical pipes, or at least pipes of the same mensure (internal cross section and shape, internal pro le) throughout their length. The basic frequency of utes in which the mensure changes (conically, exponentially, etc. The basic pitch, despite the same physical measurements (length, cross section at the ends), can differ considerably because of different internal pro les. The internal pro le also greatly affects the sound spectrum (timbre, higher harmonic oscillations) and the practical possibility of producing sound at all. So with too wide or too narrow an internal pro le, sound cannot be pro duced at all. The interior (medullary cavity) of the femur of a young bear is not a regular cylindrical shape. At the proximal end, and even more at the distal end, the bone widens in a fan shape, which greatly in uences the internal cross section of cortical bone. Determining the basic frequen cies of a ute with such an internal pro le from the physical measure ments of the bone is extremely dif cult. An additional dif culty in our nd was caused by the fact that the exact length of the suspected ute is unknown, since the bone was damaged at the ends. However, we con cluded that it could not have been much longer than as it was found, since bone itself does not allow this. Changes in embouchure and strength of blowing represent a problem in determining the basic frequency of the ute. They can cause major dif ferences in the basic pitch—by a whole tone or more—in the same ute and with the same method of blowing. A range of basic tones is shown for each ute because of changes to the embouchure and strength of blowing. Empty notes represent boundary values of a speci c tone due to changes in the embouchure and strength of blowing, and lled notes represent our estimate of tones that appeared most often with speci c combinations of holes. An arrow above a note marks the direction of deviation of the marked intonation by around twenty cents, and a double arrow by around forty cents. Filled arrows (triangles) replace notes of a high penetrating whistle, which were dif cult to measure and notate. The effect of partial closing and stopping of the lower end of the instrument is marked with a vertical line under the basic note. The light elds represent combinations, which we obtained with the two holes completely preserved on the original. We obtained interesting results from testing and comparing almost identical plaster and metal reconstructions (casts). Their distal and proximal ends were processed by hand and kept as uniform as possible. The deviation of basic intonation of individual utes was surprising, assessed at more than a whole tone. Exact measurement was dif cult to perform because of the change in pitch due to the embouchure and strength of blowing. With cast metal utes, which had no hand molding, no such deviation occurred—they were almost indistinguishable. The deviation can be explained by the different internal pro les of utes from plaster and dif ferent positions against the mouth of the experimenter. Thus even small deviations can create considerable changes in the basic tone of similar instruments. Even greater deviation among utes of the same length and played in the same way can be noticed in comparing various reconstructions having similar mouthpieces (gures 15. Here, too, the internal shape and size of the mouthpiece (manner and shape of distal widening of the bone at the metaphysis and how thoroughly the spongiosa is removed) are clearly very important. A new dif culty in determining basic pitch was seen in the various pos sible ways of blowing into the ute. It follows from this that we can only guess at the more exact basic frequency of the ute. Even greater dif culties appeared when we attempted to determine the selection of sounds (possible musical scale) that could be drawn from a ute, since a change in pitch can be achieved in a number of ways: changing the embouchure and strength of blowing, partly or completely closing the lower end of the instrument, overblowing, and lengthening and shortening of the length of the instrument. We successfully used all these methods in our experiments, and they appreciably affected the pitch. Embouchure and strength of blowing had an in uence on chang ing the basic tone and had similar effects on other possible tones (gures 15. Partly closing the lower part of the ute theoretically enables a con tinuous change of pitch between closed and open instruments. With our reconstructions, we succeeded in executing small, continuous changes of tone, and the instruments quickly transformed from closed to open type (or vice versa). Such closure could also be achieved by placing the ngers at the lower end of the instrument (stopping the hole). In such a way, the tone could be precisely changed continuously downward by more than a perfect fourth. The length of the instrument could be extended in a simple way only with the hand, but this did not have much effect in 260 Drago Kunej and Ivan Turk Fig. However, it could be combined successfully with partial or complete closure of the end of the ute.
