Il quadro generale di una fenomenologia statunitense della musica

This article sets out the overall framework within which American music phenomenologists operates. A widely accepted definition of the word phenomenology, together with a basically eclectic attitude and a boundary issue between musicology and philosophy, is identified. The impetus to the article is provided by an anti-positivistic polemic and a plea in defence of the meaning and concreteness of musical experience. These aspects then combine in a critique of traditional musical analysis in its positivistic matrix. S.K. Langer's philosophy, as the inspiration of this polemic, is examined in the central part of the article. However, the author's distancing from the idealistic aspects of his esthetics is covered, in particular the downplaying of the sound-sensitive level and the condemnation of musicology in general. Sense and sensitive materials, wide philosophical options and concrete procedures of music analysis are what these authors look for in phenomenology as a means to reconcile humanistic and technical culture. Therefore, the article is not so much a condemnation as an attempt to refound musicology in its entirety, with particular reference to contemporary music.     

Five points and a lament about Range and Cotton's "Reports of assent and permission in research with children: illustrations and suggestions

This comment responds to an article by Range and Cotton (1995) on reporting of parental permission and child assent procedures in published articles for 4 psychology journals. Issue is taken with the assumptions, methodology, interpretations, and implications of listing researchers in the Range and Cotton article. There is no evidence researchers failed in their ethical obligations or that children were put at risk. Reporting permission/assent in publications is not an ethical requirement. Listing researchers as "failing" to do something not part of an ethical code is lamentable. Too many unfortunate implications and problems can be derived from Range and Cotton's analysis and conclusions.     

A review and critique of the process approach in neuropsychological assessment

This paper surveys the process approach literature with an emphasis on higher level cognitive functions like attention and concentration, learning and memory, and problem solving and executive functioning. In particular, it discusses organizational strategies and kinds of errors found on a variety of tests as well as behavioral, situational, and interpersonal issues as they relate to test procedures. It critiques the process approach and suggests future directions.     

“How dare you sport thus with life?”: Frankensteinian fictions as case studies in scientific ethics

Fictional scenarios involving "hard" science offer what are in effect case studies of scientific ethics. From his analysis of Shelley's novel, biologist Leonard Isaacs constructed a model of a "Frankenstein scenario," applicable to the dilemmas posed by the advancement of science in our time, as well as to fiction about science by such contemporary writers as Robin Cook and Michael Crichton. The special contribution of fiction to the study of ethics is that it both reflects and evaluates reality's infinite permutations. In reflecting and judging, the fictional scenarios engage our moral imagination and compel us to confront our personal ethos in relation to the evolving ethos of science.     

The ombudsman for research practice

We propose that institutions consider establishing a position of “Ombudsman for Research Practice”. This person would assume several roles: as asounding board to those needing confidential consultation about research issues — basic, applied or clinical; as afacilitator for those wishing to pursue a formal grievance process; and as aneducator to distribute guidelines and standards, to raise the consciousness regarding sloppy or irregular practices in order to prevent misconduct and to promote the responsible conduct of research. While there are compelling features to this position, many complex issues need to be considered and resolved. We invite readers to respond to questions we raise in the text.     

Extraction of relief from visual motion

We quantified the ability of human subjects to discriminate the relative distance of two points from a slanted plane when viewing the projected velocities of this scene (orthographic projection). The relative distance from a plane (called relief) is a 3-D property that is invariant under linear (affine) transformations. As such, relief canin principle be extracted from the instantaneous projected velocity field; a metric representation, which requires the extraction of visual acceleration, is not required. The stimulus consisted of a slanted planeP (specified by three points) and two pointsQ ₁ andQ ₂ that are non-coplanar withP. This configuration of points oscillated rigidly around the vertical axis. We have measured thesystematic error andaccuracy with which human subjects estimate the relative distance of pointsQ ₁ andQ ₂ from planeP as a function of the slant of_P. The systematic error varies with slant: it is low for small slant values, reaches a maximum for medium slant values, and drops again for high slant values. The accuracy covaries with the systematic error and is thus high for small and large slant values and low for medium slant values. These results are successfully modeled by a simple relief-from-motion computation based on local estimates of projected velocities. The data are well predicted by assuming (1) a measurement error in velocity estimation that varies proportionally to velocity (Weber’s law) and (2) an eccentricity-dependent underestimation of velocity.     

Are microsaccades responsible for the gap effect?

Extinguishing a fixation point shortly before, or concurrently with, the onset of a peripheral visual target reduces the latency of saccades to that target. Saslow (1967) hypothesized that thisgap effect might occur because fixation point offsets reduce the incidence of corrective microsaccades with an associated saccadic refractory period. In the present study, a robust gap effect was obtained. However, using a Purkinje image eyetracker with 1 arcmin of resolution, we found that fixation point offsets had no effect on the occurrence of microsaccades and that the occurrence of microsaccades had no impact on the magnitude of the gap effect. Microsaccades therefore do not appear to play any part in the production of the gap effect.

An affordable computer-aided method for conducting Morris water maze testing

A relatively inexpensive and reliable computer-aided method for assessing Morris water maze performance is described. The procedure uses SigmaScan digitizing software (Jandel Scientific, San Rafael, CA) to collect distance swum data, while escape latencies are measured with a hand-held stopwatch. Swim paths are videotaped for subsequent viewing and saved on disk as data sets ofx,y coordinates. At a later time,x,y data files are printed and analyzed to obtain additional performance measures (e.g., distance swum in previous reinforced quadrant, heading angle, etc.). Intra- and interrater reliabilities associated with this method are presented. Correlation coefficients in ther = .85?.90 and above range are reported for both reliability types. Given its approximate cost of $1,500 (excluding the price of an IBM-compatible computer), the present procedure potentially can aid in performing instructional and research activities at small colleges which typically lack extensive equipment budgets.
