JOURNAL FREE ACCESSA tone (500 c/sec, 95 phons, 5 sec in duration) was presented to a cat during slow-wave sleep until the temporal cortex failed to desynchronize on 3 successive trials, being followed by a dishabituation trial when the tone of a different frequency (1000 c/sec) was given. Data with 10 adult cats showed that cortical desynchronization decreased and disappeared with trials and recovered, although not completely, on the dishabituation trial. Similar data were obtained in hippocampal theta activity except that it habituated faster than the cortical activity. Mean theta frequency also decreased less markedly with trials. Peripheral responses (head movement, respiratory response) failed to be elicited in some cats even on trial 1 but as a group they were habituated and extinguished but not dishabituated.View full abstractDownload PDF (574K) -

JOURNAL FREE ACCESSChumbley (1972) proposed his duoprocess theory for 4-category concept identification learning as having the same power to describe the data as Trabasso and Bower (1964)'s SP model. In this paper, it is pointed out that, despite Chumbley's insistence, the evidence to which he did not refer is not compatible with his model. Further, an experiment was performed to test the two models in terms of another measure, i.e., the distribution of the differences between the trials of the last error.View full abstractDownload PDF (645K) -

JOURNAL FREE ACCESSTo examine the quantity and quality of experience required to acquire a phrase structure grammar, the numbers of exemplars and reference conditions were controlled, using a miniature artificial language. The results showed that (a) under Semantic Referent Conditions a constant amount of experience was necessary for syntax acquisition;(b) semantic referents facilitated the overall acquisition of the syntax; but (c) even under Non-Semantic Referent Conditions some Ss could acquire the syntax. These results were interpreted as to suggest that a constant amount of experience based on position learning together with the mediation of semantic referents was required for syntax acquisition, and the LAD hypothesis proposed by Chomsky and others was discussed from an empirical point of view of language acquisition.View full abstractDownload PDF (718K) -

JOURNAL FREE ACCESSUsing 2 well practiced Ss, visual reaction times were measured to targets of 4 sizes between 18 and 116 min of arc at a fixed luminance level of 93 log cd/m2. The targets were presented to 11 retinal loci: fovea and 10°, 20°, 30°, 40°, and 50° on both the nasal and the temporal side of the fovea along the horizontal meridian of the right eye. Reaction time decreased as a function of increasing target size and increased as a function of increasing retinal eccentricity. It was also found that reaction time to stimulation on the nasal side of the retina was faster than to the temporal side. It was suggested that increasing spatial summation might play a critical role in determining reaction time.View full abstractDownload PDF (530K) -

JOURNAL FREE ACCESS240 undergraduates were given 3 texts to learn, each with an immediate retention test, and finally a delayed test of the first text. These 3 texts consisted of the same set of general attributes with changed and unchanged specific details. One half of the Ss learned related prose texts (R) where changed details could be predicted from the others and the other half learned unrelated ones (U) where details were independent from each other. Both cued recall and free recall of the changed details of the first text showed significant decline between immediate and delayed test even in R, but this was significantly smaller than in U. 74 R Ss with increased or unchanged retention of attributes, showed increased recall of the details.View full abstractDownload PDF (391K) -

JOURNAL FREE ACCESSIn order to examine the generality of reflection-impulsivity, 51 5-6-year-olds were given, in addition to Kagan's MFF, a tactual-visual matching task (TVM) of geometric shapes and two conceptual matching tasks: Referential communication with inadequate message where the child as receiver had to ask questions to make a correct choice, and a revised version of Olson's conceptual pattern matching. Latency and error measures of MFF and TVM were all significantly correlated to each other. Among the 24 correlations between these 4 measures from the perceptual tasks and 3 measures each from conceptual ones, i. e., amount of instrumental information-seeking, number of errors and number of guesses, 21 had the expected signs (+, -) and 9 were significant in the expected direction. Partialing out verbal ability made only 2 of the 9 insignificant.View full abstractDownload PDF (621K)
