    A case of amnesic aphasia was reported from the viewpoint of cognitive psychology.
    The major findings were as follows:
    1) The subject demonstrated defective recall, but she had normal recognition. These findings suggest that she has a defect only in the search process for word information. They also support the“model of double process”, and show that the search process is independent of recognition.
    2) The subject did not exhibit the “tip of the tongue phenomenon” even when she could not retrieve words. This search was performed at a very low level, and she was unable to search partially.
    3) She was unable to retrieve “shinkansen” (bullet train) with the hint of “shi-n-ka-n-se”. This phenomenon suggests that she may remember the word as one unit.
    4) She was unable to find a target word regardless of all hints. Her main search was automatic and she showed difficulty in the controlled process of word retrieval.

    The aim of the present study is to clarify the temporal variation of verbal and tapping reaction times in response to repetitive auditory and visual stimuli. Thirteen normal adult subjects were requested either to produce the consecutive sound /papapa---/ or to push an electrical switch in accordance with repetitive stimuli at a variety of frequency rates. It was shown that there are some differences in reaction times between auditory and visual presentations. With the auditory stimuli, repetitive reaction times were shorter than the mean simple reaction time for all frequency rates. Furthermore, such auditory reaction times frequently became negative, which means that the reaction was provoked in advance of the stimulus itself. With visual stimuli given at a slow rate, repetitive reaction times were almost the same as the simple reaction time; with fast repetitive visual stimuli, reaction maneuvers were unable to keep pace.

    This paper reports on the analysis of a type of articulation error which has been generally called“nasal articulation.”
    The results are summarized as follows:
    1) Soundspectrograms of this type of error showed formant patterns different from those of normal sounds. For consonants, spike fills and weak noise components ranging from low to high frequency were observed. For vowels, formants of nasal resonance were observed at the frequency range of 200 to 300 Hz.
    2) Abnormal articulatory movements were observed by cineradiography, fiberscopy and electro-palatography. In this type of articulation error, contact between the tongue and hard or soft palate closes the oral cavity and directs the air flow and sound to the nasal cavity. When the error occurs in stop or fricative consonants, stop closure or fricative constriction are made at the nasopharyngeal port. In vowels, articulatory movements are similar to those for /n/ or /η/.
    From the foregoing, the author proposed“nasopharyngeal articulation”as the most suitable name indicating this type of articulation error.

    It is well known taht control by the auditory system for voicing is very significant in order to produce a good vocal sound. In normal phonation, this auditory feedback regulation plays an important role in daily voice production. However, this auditory regulation cannot be performed normally in daily clinical examination of the phonatory function because the patient cannot hear his/her own voice naturally when wearing a mouthpiece or mask.
    To remedy this circumstance, we have recently designed a system in which a patient being examined can listen to his/her voice naturally. The patient's voice is picked up by a pitch extract amplifier and then introduced to an equalizer amplifier, by which it can be equalized fairly naturally. The equalized voice can be heard through open type headphones. Thus auditory feedback regulation can be maintained normally during examination of the voice.
    In this paper, the method is demonstrated, and the results are discussed mainly from the viewpoint of application in daily clinical examination.

    For the purpose of clinical evaluation of aerodynamic conditions in phonation, we developed a system to measure expiratory lung pressure using the airway interruption method, combined with measurements of the air flow rate, vocal pitch and intensity. In this system, an air shutter is connected to the mouthpiece of a PS-77, made by the Nagashima Medical Instrument Co., which measures the air flow rate simultaneously with the vocal pitch and intensity.
    The expiratory air flow during sustained phonation is momentrarily interrupted by closing the shutter when the subject holds the mouthpiece airtight with his lips. The air pressure at the shutter is measured at the moment when it reaches equilibrium with the subject's lung pressure.
    The output signals of the four parameters are sampled by microcomputer. Time curves of the parameters and sample values at the time point of measurement are displayed on a CRT screen. Data can also be printed out on a recording sheet or stored in a minifloppy disc.
    This method is non-invasive and easy for the patient to perform. Our clinical experience has shown this method to be very practical and useful for evaluating aerodynamic conditions in phonation.
