Laser can stimulate sound wave, its possible for fiber laser to evoke neural activity safely and produce the auditory perception, this acts as the electrode role in cochlear implant. Moreover, the laser is characterized by definite direction and optical signal between adjacent fibers dont readily interfere. Therefore, optical fiber cochlear implant based on optoacoustic effect is promising. The design and preparation of an experimental system based on optoacoustic effect is introduced in this paper. The selection of laser source and the control methods of optical signal were discussed, and testing results of the fiber optoacoustic effect, including the time domain waveforms and spectrograms of the evoked optoacoustic sound were given. Also, a preliminary discussion for the extended fiber array system applied in artificial fiber cochlea as an alternative to electrodes stimulation was progressed.

One hundred and eighty-nine kindergarten children were given a CVCC rhyming test which included four slightly different types of auditory differentiation. They obtained a greater number of correct scores on categories that provided maximum contrasts of final consonant sounds than they did on categories that provided less than maximum contrasts of final consonant sounds. For both sexes, significant differences were found between the categories; although the sex differences were not significant, girls made more correct rhyming responses than boys on the most difficult category.

Abstract. Random response is a very common aberrant response behavior in personality tests and may negatively affect the reliability, validity, or other analytical aspects of psychological assessment. Typically, researchers use a single person-fit index to identify random responses. This study recommends a three-step person-fit analysis procedure. Unlike the typical single person-fit methods, the three-step procedure identifies both global misfit and local misfit individuals using different person-fit indices. This procedure was able to identify more local misfit individuals than single-index method, and a graphical method was used to visualize those particular items in which random response behaviors appear. This method may be useful to researchers in that it will provide them with more information about response behaviors, allowing better evaluation of scale administration and development of more plausible explanations. Real data were used in this study instead of simulation data. In order to create real random responses, an experimental test administration was designed. Four different random response samples were produced using this experimental system.

It is now accepted that older adults have difficulty recognizing prosodic emotion cues, but it is not clear at what processing stage this ability breaks down. We manipulated the acoustic characteristics of tones in pitch, amplitude, and duration discrimination tasks to assess whether impaired basic auditory perception coexisted with our previously demonstrated age-related prosodic emotion perception impairment. It was found that pitch perception was particularly impaired in older adults, and that it displayed the strongest correlation with prosodic emotion discrimination. We conclude that an important cause of age-related impairment in prosodic emotion comprehension exists at the fundamental sensory level of processing.

SummaryThe purified anticoagulant split product of fibrinogen has antifibrinolytic and anti-fibrinogenolytic activity. This was investigated by lysis times of fibrin and by the rate of disappearance of fibrinogen in plasma and in a purified system. A new method was used to measure fibrinogenolytic activity. In the experimental system which we have used no indication of additional breakdown of the anticoagulant split product in the presence of fibrinolysin was obtained.

ABSTRACT The definition of a RECEPTOR* in terms of a receptive site, an executive site and a coupling mechanism, is followed by a general consideration of four binding criteria, which include hormone specificity, tissue specificity, high affinity and saturation, essential for distinguishing between specific and nonspecific binding. Experimental approaches are proposed for choosing an experimental system (either organized or soluble) and detecting the presence of protein binding sites. Techniques are then presented for evaluating the specific protein binding sites (receptors) in terms of the four criteria. This is followed by a brief consideration of how receptors may be located in cells and characterized when extracted. Finally various examples of oestrogen, androgen, progestagen, glucocorticoid and mineralocorticoid binding to their respective target tissues are presented, to illustrate how researchers have identified specific corticoid and mineralocorticoid binding in their respective target tissue receptors.
