Effects of prior knowledge and response bias upon recognition memory for a story
The present study was designed to evaluate the integration hypothesis and the response bias hypothesis for explaining the fragility of children's eyewitness memory, by varying the plausibility of postevent information and the strength of response bias in recognition tests. Preschool children were told a story in which a boy named Ken saw a housebreaker stealing various objects and the postevent information was also incorporated into the story. Th…
Changes in contingent negative variation (CNV) as a function of paired associate learning
The present study was designed to investigate the effect of paired associate learning upon contingent negative variation (CNV). A total of 14 subjects were given paired associate learning items in a discriminative reaction time paradigm. The results obtained showed that as the frequency of correct responding increased the amplitude of CNV significantly increased and CNV resolution time and reaction time significantly decreased. The co-variation o…
Developmental Changes in Conceptual and Color Clustering in Young Children
Two experiments were performed to examine the developmental changes in clustering criteria, using preschool children as subjects. The subjects were required to memorize the materials which were selected so as to be classifiable on the basis of conceptual categories or color categories. The results of Experiment I indicated that conceptual clustering increased with age while color clustering tended to decrease with age. The results of Experiment I…
Developmental Changes in the Structure of Semantic Memory
The present study was designed to examine the developmental change in the structure of semantic memory by using multidimensional scaling. Preschool children (4-yr.-old and 5-yr.-old) performed 56 sorting tasks with 56 possible combinations of 3 words from 8 familiar words. A three-dimensional solution of the data showed (1) dimension I may be interpreted as a taxonomic category and the combination of Dimensions II and III as a complementary relat…
Effects of Subcategorical Cues on the Release of Proactive Inhibition
The effects of subcategorical cues on the release from proactive inhibition were examined. Analysis of variance with 2 × 2 factorial design was employed, in which the presence or absence of subcategorical change and of subcategorical cues at the time of recall of the release trial were main sources. Results indicated that the presence of the subcategorical cues produced a substantial degree of PI release when the subcategory was changed, while th…
Slowly Changing Potential Modified by Controlled Respiratory Cycle
The present study was designed to investigate the effect of respiration upon slowly changing potential (SCP) using controlled respiratory cycles. EEG and respiration were monitored under 3 different respiration conditions, 7.5, 15, and 30 cycles per min. The results indicated that SCP amplitude decreased as a function of respiration rate. Cross-correlation analysis also showed that SCP variation is correlated with respiration phase. Considering t…
Changes of Contingent Negative Variation (Cnv), Visual Evoked Response, and Reaction Time During Repeated Trials in Simple Reaction Time Task
The purpose of the present study was to understand both the behavioral (reaction time) and physiological (contingent negative variation and visual evoked response) bases of habituation using a simple reaction time paradigm. Each of 16 adult Ss was given a total of 200 trials with a 1000 msec S1-S2 interval. The results showed that the amplitude of contingent negative variation decreased and reaction time increased over the trial blocks. The visua…
Retroactive Inhibition in Free Recall of Categorized Word Lists
Unlearning hypothesis and limited capacity hypothesis to explain RI in free recall were evaluated by varying the number and the size of categories of the lists in Experiment 1. The results indicated that RI in free recall is due to the limited capacity of human memory. Experiment 2 was designed to investigate whether RI reflects the limited capacity of storage or the limited capacity of retrieval of human memory, by providing category names as re…
Effects of Horizontal and Vertical Eye Movements and Eye Blink Upon Human Visual Evoked Responses
The effects of horizontal and vertical eye movements upon human visual evoked responses were investigated in Experiments 1 and 2. Results showed that both horizontal and vertical eye movements have no effect upon the averaged evoked response. The effects of eye blink were examined in Experiment 3.Eye blink increased Amplitudes C (P2-N2) and D (N2-P3) of the averaged evoked response, but had little effects on Amplitudes A (N1-P1) and B (P1-N2)
Effects of Reaction Time Task Upon Human Visual Evoked Response Under Conditions of Fixed and Variable Foreperiods
In order to evaluate the effect of attention upon human visual evoked response, reaction time task and no reaction time task were combined with fixed vs. variable interstimulus intervals in a 2 by 2 factorial design. In Experiment 1 a flashing light 8cm×8cm square was presented 30 times to 8 adultSs. The averaged evoked response did not vary with any of the factors. In Experiment 2 a smaller flashing light 4cm×4cm square was presented 30 times to…
Effects of Stimulus Rotation, Shape, and Visual Angle Upon Human Visual Evoked Response
The effects of stimulus size, rotation, and shape upon the averaged evoked response were investigated in Experiment 1 and 2. The evoked response (P1-N1; P2-N2; N2-P3) increased as a function of stimulus size in both experiments, while no effect of rotation was found. The later evoked response components (P2-N2; N2-P3) to the large square and to the triangle were different in Experiment 2. The effect of visual angle upon the evoked response was in…
Human Visual Evoked Response as a Function of Stimulus Size and Density of Patterned Stimulus
Human visual evoked response was investigated as a function of stimulus size of diffuse light (Experiment 1) and density of patterned light (Experiment 2). The effect of rotation of the patterned light was also investigated (Experiment 2). The results obtained in Experiment 1 indicated that the mean amplitudes of the evoked response components (Amplitude A, B, and D) significantly increased and the mean latencies of the evoked response components…
