Surface slant (the angle between the line of sight and the surface normal) is an important psychophysical variable. However, slant angle captures only one of the two degrees of freedom of surface orientation, the other being thedirection of slant. Slant direction, measured in the image plane, coincides with the direction of the gradient of distance from viewer to surface and, equivalently, with the direction the surface normal would point if projected onto the image plane. Since slant direction may be quantified by the tilt of the projected normal (which ranges over 360 deg in the frontal plane), it is referred to here assurface tilt. (Note that slant angle is measured perpendicular to the image plane, whereas tilt angle is measured in the image plane.) Compared with slant angle’s popularity as a psychophysical variable, the attention paid to surface tilt seems undeservedly scant. Experiments that demonstrate a technique for measuring apparent surface tilt are reported. The experimental stimuli were oblique crosses and parallelograms, which suggest oriented planes in 3-D. The apparent tilt of the plane might be probed by orienting a needle in 3-D so as to appear normal, projecting the normal onto the image plane, and measuring its direction (e.g., relative to the horizontal). It is shown to be preferable, however, to merely rotate a line segment in 2-D, superimposed on the display, until it appears normal to the perceived surface. The apparent surface tilt recorded in these experiments corresponded closely to that predicted by assuming the 3-D configurations consist of equal-length lines and perpendicular intersections. 相似文献

The definition and role of the expert witness is reviewed. Two conceptual systems for viewing the world, the scientific method and the adversarial system, are compared. The reconciliation and integration of these two discrepant systems are discussed in terms of input versus outcome. The rules of evidence, as well as problems of communication between the systems, are reviewed with the aim of providing expert witnesses with a better understanding of effective testimony. Finally, collaboration between the two systems is called for in order to provide guidelines for both neuropsychologists and attorneys. 相似文献

This study examined the differential evaluation of male and female stimulus cues and the effect of subject's androgyny level on their evaluations. Male and female college students filled out the Bem Sex Role Inventory (1974) and responded to set of five in-basket tasks taken from the Rosen, Jerdee, and Prestwich (1975) study of male managers. Sex of subject, sex of stimulus cue in the in-basket tasks, and androgyny level were varied in a series of 2 X 2 X 3 analyses of variance. On some tasks, male and/or female subjects responded in a sex role stereotyped manner. There were no effects for androgyny level. The discussion focused on circumstances under which stereotyping occurs and implications of the study. 相似文献

A series of experiments was conducted to investigate the possibility of hemispheric specialization for judgments of the simultaneity of two light flashes. Right-handed subjects adjusted two light flashes until they appeared simultaneous. The comparison of measures derived from the two possible orders of the light flashes suggested that the right hemisphere of right-handed subjects performed the function of ordering visual stimuli in time. Two further experiments examined an alternative explanation, that of a left-to-right scanning mechanism, the results of which also suggested a hemisphere explanation. The results of these experiments are discussed in terms of previous research and theories which located a temporal ordering mechanism in the speech hemisphere. 相似文献

The present study undertakes a comprehensive and critical review of the body of empirical work on entrepreneurial passion. In particular, we document how the “first generation” of research on entrepreneurial passion and work passion in entrepreneurs has gained growing attention in various sub-fields of entrepreneurship research including entrepreneurial management, psychology, and finance. We provide an overview over theories used, definitions and measurements adopted, research methods utilized (e.g., qualitative vs. quantitative, survey-based vs. experimental/intervention), the thematic focus of studies, and unit of investigation (e.g., individual vs. team). We not only flag the problems of inconsistencies and limitations with respect to theory use, the making of causal inferences, and the conceptualization and measurement of entrepreneurial passion in existing studies (e.g., jingle fallacies), but also review the antecedents and outcomes of entrepreneurial passion identified in prior work and work where it had been examined as a moderator. Following this, we offer a research agenda with concrete suggestions to act as a foundation for the “second generation” of entrepreneurial passion research that proactively addresses the issues and gaps identified in our review. Finally, we also highlight how insights from the entrepreneurial passion literature can inform scholarship on passion more broadly. 相似文献

It is possible to design effective, pragmatically useful memory interventions for persons with Dementia of the Alzheimer's Type (DAT). A review of successful memory interventions for such populations is presented. A particularly effective intervention technique, spaced-retrieval, is described and the theoretical basis for its effectiveness is discussed. A detailed account is presented of a spaced-retrieval intervention in which persons with DAT are trained to learn and utilize a strategy, i.e., remembering to use a calendar listing daily activities. Directions for future research in this area are offered. 相似文献

To determine the demographics, DSM-III-R disorders diagnosed, indications used in recommending psychoanalysis, previous treatment histories, use of medication, and length of treatment in patients in psychoanalysis in the U.S., Canada, and Australia, a mail survey of practice was sent to every other active member of the American Psychoanalytic Association and every member of the Australian Psychoanalytical Society. This supplemented an earlier survey sent to all Ontario psychoanalysts. The response rates were 40.1 % (n = 342) for the U.S., 67.2% (n = 117) for Canada, and 73.9% (n = 51) for Australia. Respondents supplied data on 1,718 patients. The employment rate for patients increases as analysis progresses (p < .0001). The mean number of concurrent categories of disorders (Axis I, Axis II, and Disorders First Evident in Childhood) per patient at the start of treatment is 5.01 (SD = 3.66; median = 4; mode = 3). There are no statistically significant differences across countries. Mood, anxiety, sexual dysfunction, and personality disorders are most common. American Psychiatric Association / American Psychoanalytic Association peer review criteria for indicating psychoanalysis are followed for 86.5% of patients. Over 80% of patients in all three countries had undergone previous treatments prior to analysis. In the U.S., 18.2% of analysands are on concurrent psychoactive medication; in Australia, 9.6%. The mean length of analyses conducted in the U.S. is 5.7 years, in Australia 6.6, and in Canada 4.8. Psychoanalytic patients in all three countries have similar rates of DSM-III-R psychopathology, and many indications of chronicity. 相似文献

Impulsivity is regarded as a core feature of borderline personality disorder (BPD; M. C. Zanarini, J. G. Gunderson, & F. R. Frankenburg, 1989) despite lack of evidence from laboratory research (D. M. Dougherty, J. M Bjork, H. C. G. Huckabee, F. G. Moeller, & A. C. Swann, 1999). This study examined impulsivity in incarcerated women with BPD using a passive avoidance task (J. P. Newman & W. A. Schmitt, 1998) and the Impulsiveness-Monotony Avoidance-Detachment inventory (IMD; D. Schalling, 1978). As predicted, incarcerated women diagnosed with BPD committed more passive avoidance errors and reported more impulsivity on the IMD than controls. These findings identify disinhibition as a potentially important component of the impulsivity that characterizes BPD. Specifying the impulsive behavior identified with BPD may contribute to the effective assessment and management of the disorder. 相似文献
