Contrasting linguistic and nonlinguistic processing has been of interest to many researchers with different scientific, theoretical,
or clinical questions. However, previous work on this type of comparative analysis and experimentation has been limited. In
particular, little is known about the differences and similarities between the perceptual, cognitive, and neural processing
of nonverbal environmental sounds and that of speech sounds. With the aim of contrasting verbal and nonverbal processing in
the auditory modality, we developed a new on-line measure that can be administered to subjects from different clinical, neurological,
or sociocultural groups. This is an on-line task of sound to picture matching, in which the sounds are either environmental
sounds or their linguistic equivalents and which is controlled for potential task and item confounds across the two sound
types. Here, we describe the design and development of our measure and report norming data for healthy subjects from two different
adult age groups: younger adults (18–24 years of age) and older adults (54–78 years of age). We also outline other populations
to which the test has been or is being administered. In addition to the results reported here, the test can be useful to other
researchers who are interested in systematically contrasting verbal and nonverbal auditory processing in other populations. 相似文献

Illness course separates patients with atypical depression into tricyclic responders and nonresponders as does perceptual asymmetry. The authors therefore investigated whether the course-of-illness parameters would define groups within atypical depression differing in brain laterality. Patients with atypical depression were assessed for illness course and brain laterality. Two patient groups were defined, 1 with onset prior to age 20 plus a very chronic course, and a 2nd group having later onset or less chronic illness. Patients reporting early onset of very chronic dysphoria showed significantly less right-ear (left-hemisphere) accuracy and also differed in characteristic perceptual asymmetry when compared to patients with later onset or less chronicity. Course of illness may usefully define more homogeneous depressive subgroups within atypical depression. 相似文献

Seventy-three college students participated in a study to assess the role of self-efficacy and imperatives in social anxiety. The students were asked to speak in front of a small group of their peers and their anxiety and length of time talking were measured. Neither lower self-efficacy nor higher levels of imperative thinking at Baseline were correlated with higher levels of anxiety. The critical finding was that subjects who showed higher levels of imperative thinking at Baseline spoke for a significantly shorter period of time. This suggests that the participant's anxiety was moderated by the performance of an instrumental response, in this situation by choosing to limit the amount of time spent talking. The results suggest the centrality of imperative thinking in shaping behavior in the domain of social anxiety. 相似文献

Recent developments of three-dimensional printing of biomaterials (3D bioprinting) in medicine have been portrayed as demonstrating the potential to transform some medical treatments, including providing new responses to organ damage or organ failure. However, beyond the hype and before 3D bioprinted organs are ready to be transplanted into humans, several important ethical concerns and regulatory questions need to be addressed. This article starts by raising general ethical concerns associated with the use of bioprinting in medicine, then it focuses on more particular ethical issues related to experimental testing on humans, and the lack of current international regulatory directives to guide these experiments. Accordingly, this article (1) considers whether there is a limit as to what should be bioprinted in medicine; (2) examines key risks of significant harm associated with testing 3D bioprinting for humans; (3) investigates the clinical trial paradigm used to test 3D bioprinting; (4) analyses ethical questions of irreversibility, loss of treatment opportunity and replicability; (5) explores the current lack of a specific framework for the regulation and testing of 3D bioprinting treatments. 相似文献

The objective of this study was to determine if patients with diagnosed stage-1 hypertension could benefit by a forgiveness training program to achieve measurable reductions in anger expression and blood pressure. Twenty-five participants were randomly divided into wait-listed control and intervention groups. The control group monitored blood pressure while the intervention group participated in an 8-week forgiveness training program. At the end of eight weeks, the wait listed group became an intervention group. Those who received forgiveness training achieved significant reductions in anger expression when compared to the control group. While reductions in blood pressure were not achieved by all the participants, those participants who entered the program with elevated anger expression scores did achieve significant reductions in blood pressure. It is suggested that forgiveness training may be an effective clinical intervention for some hypertensive patients with elevated levels of anger. 相似文献

Despite the complexity and diversity of natural scenes, humans are very fast and accurate at identifying basic-level scene categories. In this paper we develop a new technique (based on Bubbles, Gosselin & Schyns, 2001a; Schyns, Bonnar, & Gosselin, 2002) to determine some of the information requirements of basic-level scene categorizations. Using 2400 scenes from an established scene database (Oliva & Torralba, 2001), the algorithm randomly samples the Fourier coefficients of the phase spectrum. Sampled Fourier coefficients retain their original phase while the phase of nonsampled coefficients is replaced with that of white noise. Observers categorized the stimuli into 8 basic-level categories. The location of the sampled Fourier coefficients leading to correct categorizations was recorded per trial. Statistical analyses revealed the major scales and orientations of the phase spectrum that observers used to distinguish scene categories. 相似文献

A new formula is developed for the relative efficiency of two tests measuring the same trait. The formula expresses relative efficiency solely in terms of the standard errors of measurement and, surprisingly, the frequency distributions of true scores. Approximate methods for estimating relative efficiency may make this function routinely available. A numerical illustration compares new and old estimates of relative efficiency for subtests from the Scholastic Aptitude Test.Research reported in this paper has been supported by grant GB-32781X from National Science Foundation. 相似文献
