This study was designed to investigate the effect of Cued Speech on the speech reception abilities of profoundly hearing-impaired children under seven conditions of presentation: audition; lipreading: audition and lipreading; cues; audition and cues; lipreading and cues; and audition, lipreading, and cues. The 18 subjects had been taught through the use of Cued Speech for at least 4 years. The subjects were presented with specially designed speech tests (syllables and key words in sentences) which had been recorded on color videotape, and they responded in writing. Speech reception scores of over 95% with the key word in sentence materials and over 80% with the syllables were obtained with lipreading plus cues, and with audition, lipreading plus cues. Equally high levels of accuracy in speech reception by such children have not previously been reported. The subjects also demonstrated the ability: to use audition with the sentence materials, both in combination with lipreading and with cues, though there were large individual differences under these conditions. Speech reception abilities in the lipreading-plus-audition condition were highly correlated with scores for speech production, whereas language attainments were correlated with reception through Cued Speech. The implications of these findings to the field of aural rehabilitation are discussed.

The ability of observers to perceive distances and spatial relationships in outdoor environments was investigated in two experiments. In experiment 1, the observers adjusted triangular configurations to appear equilateral, while in experiment 2, they adjusted the depth of triangles to match their base width. The results of both experiments revealed that there are large individual differences in how observers perceive distances in outdoor settings. The observers' judgments were greatly affected by the particular task they were asked to perform. The observers who had shown no evidence of perceptual distortions in experiment 1 (with binocular vision) demonstrated large perceptual distortions in experiment 2 when the task was changed to match distances in depth to frontal distances perpendicular to the observers' line of sight. Considered as a whole, the results indicate that there is no single relationship between physical and perceived space that is consistent with observers' judgments of distances in ordinary outdoor contexts.

Present purposes were to examine the characteristics of controlled force exertion in 28 developmentally delayed young people (14 men, 14 women), and sex differences compared to 28 normal young students (14 men, 14 women). The subjects matched their submaximal grip strength to changing demand values displayed in a bar chart on the display of a personal computer. The total sum of the differences between the demand value and grip exertion value for 25 sec. was used as an evaluation parameter for the test. The controlled force exertion was significantly poorer for the developmentally delayed group than for controls, and there were large individual differences. The developmentally delayed men scored poorer than women in coordination. Like the controls, the means between trials did not decrease significantly. For these developmentally delayed subjects, performance did not improve after only a few trials. The controlled force-exertion test is useful as a voluntary movement-function test for developmentally delayed subjects.

A group of 10 educable mentally impaired children ( M age = 10 yr., 4 mo.) were assessed for use of phonological process under three speaking conditions: production of single words, imitated sentences, and connected speech samples. Only the process of gliding showed significant differences in use among conditions. Results generally indicated that any of those three speaking conditions were viable for eliciting use of phonological processes by such subjects. Results are also discussed in terms of individual differences.

This paper reviews studies which demonstrate the importance of kinaesthesis in the acquisition and performance of motor skills. A method of measuring kinaesthetic sensitivity in children and adults (recently developed) is briefly described. Developmental trends in kinaesthetic perception are discussed and large individual differences found within age groups. It was shown that kinaesthetically undeveloped children can be trained to perceive and memorize kinaesthetic information with greatly improved accuracy. Furthermore perceptual training facilitates the performance of a drawing skill. On the basis of these results an argument is made for the importance of kinaesthesis in skilled motor behaviour.

AbstractTwo of the roles assigned to the basal ganglia in spoken language parallel very well their contribution to motor behaviour: (1) their role in sequence processing, resulting in syntax deficits, and (2) their role in movement “vigor,” leading to “hypokinetic dysarthria” or “hypophonia.” This is an additional example of how the motor system has served the emergence of high-level cognitive functions, such as language.

Cytochrome P450 1A2 (CYP1A2) is one of the major CYP450 enzymes (CYPs) in the liver, and participates in the biotransformation of various xenobiotics and endogenous signaling molecules. The expression and activity of CYP1A2 show large individual differences, due to genetic and environmental factors. In order to discover non-invasive serum biomarkers associated with hepatic CYP1A2, mass spectrometry-based, untargeted metabolomics were first conducted, in order to dissect the metabolic differences in the serum and liver between control rats and β-naphthoflavone (an inducer of CYP1A2)-treated rats. Real-time reverse transcription polymerase chain reaction and pharmacokinetic analysis of phenacetin and paracetamol were performed, in order to determine the changes of mRNA levels and activity of CYP1A2 in these two groups, respectively. Branched-chain amino acids phenylalanine and tyrosine were ultimately focalized, as they were detected in both the serum and liver with the same trends. These findings were further confirmed by absolute quantification via a liquid chromatography–tandem mass spectrometry (LC-MS/MS)-based targeted metabolomics approach. Furthermore, the ratio of phenylalanine to tyrosine concentration was also found to be highly correlated with CYP1A2 activity and gene expression. This study demonstrates that metabolomics can be a potentially useful tool for biomarker discovery associated with CYPs. Our findings contribute to explaining interindividual variations in CYP1A2-mediated drug metabolism.

And Control

Although technological innovations have changed the role of operators from active participants to supervisors of semiautomatic processes, an understanding of the cognitive demands of supervisory control has not kept pace. In particular, little is known about when, and how well, operators might intervene and switch control from automatic to manual. This research addresses this issue by monitoring the information use and control actions of operators of a simulated semiautomatic pasteurization plant. The results of this experiment shows that individual differences in operators” monitoring patterns during the normal operation of the plant correspond to differences in their ability to mitigate the effects of faults. Specifically, an operator who controls the plant well during both normal and fault conditions tends to observe the plant frequently, integrating control actions with other control actions, and does not fixate on narrow sub-systems of the plant. On the other hand, an operator who performs poorly when exposed to faults tends to observe the plant less often, fails to integrate control actions, and fixates attention on a narrow subset of plant variables. Although all operators interacted with the plant using the same interface and automation, large individual differences in the operators” monitoring patterns, and the associated differences in performance suggest that individuals” attitudes, motivation, and training may play a critical role in the successful implementation of automation.
