JOURNAL FREE ACCESSThe heart rate of the curarized rat gradually increased and decreased over a period of avoidance training depending upon the direction to which the heart rate change to CS was reinforced. When shaping was made for increases of heart rate, the conditioned heart rate increase to CS was abolished under propranolol, while it was clearly observed under two types of atropines. The reverse pattern was shown for shaping of decreases. The conditioned heart rate change was not depressed under phentolamine or saline. These results indicate that shaping the heart rate for increases and for decreases is indeed possible through the formation of avoidance conditioning of the heart rate change to CS, and the heart rate increase and decrease to CS are differentially mediated through increased tones of the sympathetic and parasympathetic systems innervating cardiac muscle, respectively.View full abstractDownload PDF (848K) -
SUSUMU TAKAHASHI1977 Volume 19 Issue 3 Pages 114-120

Released on J-STAGE: February 24, 2009
JOURNAL FREE ACCESSA primary concern of the present study was a comparative test between the weighted average and the change-of-meaning hypotheses of the context effect, by determining what changes in the magnitude of the context effect occur as a result of changes in serial position of a test adjective within the sequence. A test adjective was interpolated at various points within a set of three adjectives. A person description was presented by both the serial and the simultaneous mode. The results showed that the context effect varied systematically as a function of serial position under the serial presentation mode, whereas the context effect had no dependence on serial position in the simultaneous mode, producing the constant context effects. The person impression ratings exhibited a trend that the serial presentation mode produces a primacy effect and the simultaneous mode yields no order effect. The results of the two kinds of judgment provide evidence to support the weighted average model.View full abstractDownload PDF (591K) -

JOURNAL FREE ACCESSGoldfish were classically conditioned with food or shock as the US for three days using 20 trials per day. The CS was a ten sec light and the CR was activity during the CS-US interval. Fish conditioned with shock as the US learned to decrease activity during CS presentations, while fish trained with food as the US learned to increase activity during CS presentations (inhibition of delay). Tests with novel (disorienting) stimuli (combinations of flashing light and clicks) during CS-US intervals produced disinhibition to the lower intensity novel stimuli and external inhibition to the highest intensity novelstimulus. Fish with shock as the US showed increased responding for all novel stimulus intensities.View full abstractDownload PDF (623K) -

JOURNAL FREE ACCESSLevelt's model is based on the assumption that the mean dominance time (t) of one eye is a function only of the stimulus strength (λ) in the other eye. He concluded that the assumption was supported by his experiments which were the two-choice rivalry task. But under the two-choice alternation process the assumption can also be expressed by another way that the mean suppression time (τ) of one eye is a function only of λ in the same eye. Any experiments under the two-choice alternation process can not test which assumption is correct. The present experiment, whose alternation process was intermittent, was performed to examine which assumption was correct. It has been proved that t is a function of λs in both eyes, but τ is a function only of λ in the same eye. It seems that Levelt's model should have been based on the latter assumption.View full abstractDownload PDF (470K) -

Released on J-STAGE: February 24, 2009
JOURNAL FREE ACCESSThe purposes of this experiment were: 1) To examine the conceptual coding hypothesis, and 2) to investigate how verbal and imaginal encoding strategies interact with shape complexity to either enhance or disturb recognition. One hundred subjects were given a recognition test following stimulus predifferentiation trainings. Results were: a) The recognition of complex shapes in the relevant labeling condition was superior to that in the irrelevant labeling condition. There was no difference between the labeling conditions on the recognition of simple shapes, and b) for complex shapes only the verbal encoding strategy should be easily available, whereas there was a possibility that for simple shapes both verbal and imaginal encoding strategies should be probably available.View full abstractDownload PDF (565K) -
PRELIMINARY REPORT ON TRANSACTION WITH INTEROCEPTIVE FEEDBACK IN THE DISCRIMINATION OF CARDIAC ACTIVITYKEIICHI HAMANO1977 Volume 19 Issue 3 Pages 143-148
Published: December 30, 1977
Released on J-STAGE: February 24, 2009
JOURNAL FREE ACCESSThe present study was designed to investigate the possibility of interoceptive detection of cardiac activity and the effects of concentration and knowledge of results, on it. Twenty college students and six grade holders in Karate formed three groups. Different types of exteroceptive tactile feedback signal for discrimination were used:(a) Signal that is contingent upon cardiac activity, and (b) one that is dependent on the pre-recorded cardiac events. The experiment consisted of three periods: Pre-Training, Training, and Post-Training. A significant over-all improvement in interoceptive cardiac detection was evidenced. In addition, differences were statistically found between the combined conditions of concentration and knowledge in Karate subjects and the students. While subjects' reports for discriminative cues suggest that the strength of concentration may be a relatively important factor in the interoceptive detection, it was recommended that further investigation examine it within the context of a combination of this training with an additional procedure.View full abstractDownload PDF (433K) -
