Computer-Based Precision Learning: A Course Builder application

An interactive tutoring and evaluation system, the Computer-Based Precision Learning System has been evolving at Jacksonville State University since its inception in 1978. Based on the Precision Teaching goal of developing fluency in learners, the Computer-Based Precision Learning System reinforces high frequencies of correct student responding. The system relies on the flexibility of Course Builder, a symbolic, icon-based programming language for Macintosh microcomputers. Course Builder is described from both the designer’s perspective and the student’s perspective. Its strengths and weaknesses are also discussed. Data from three semesters of a personality theories course indicated that students quickly reached mastery on the system, performing at over 22 correct responses per minute. Their fluency generalized to essay performance as well. Implications for using the Computer-Based Precision Learning System to develop measurably effective instructional strategies are discussed.     

A multiple-risk interaction model: Effects of temperament and divorce on psychiatric disorders in children

Effects of family status on the trajectory of problematic temperament-adjustment at 1 to 10 years of age and associated psychiatric disturbance 8 years later were examined in an epidemiological sample of 648 children. After adjusting for predivorce temperament-adjustment and background factors, logistic regression yielded independent effects of single custodial mother (SCM) family status for increased risk of disruptive and anxiety disorders, and of stepfamily status for increased risk of disruptive disorders. Increased risk of psychiatric disorders was more pervasive for SCM family boys versus intact family boys than for SCM family girls versus intact family girls, however only significantly more so for depression. No significant sex interaction was observed for stepfamily status. When girls and boys were treated independently, patterns of family status and outcomes of internalizing disorders varied. In stepfamilies, an elevated risk of depression and anxiety disorders was observed in girls but not boys, whereas in SCM families an elevated risk of depression was observed in boys but not girls. Within each family status group there was support for an altered risk of later psychiatric disorders given specific problematic predivorce temperament-adjustment characteristics. Implications for future research and treatment are discussed.The research described was supported by grants from the National Institute of Mental Health and by the W. T. Grant Foundation.     

The Relationship Between Experience and Attitudes Concerning Epilepsy1

Research indicates that epilepsy is a misunderstood and stigmatizing disorder. The present study examined whether various levels and types of experience with epilepsy are related to attitudes about the disorder. It was hypothesized that certain types of direct experience with epilepsy (e.g., knowing people with epilepsy) are related to positive attitudes about the disorder, whereas other types of direct experience (e.g., witnessing seizures) are related to negative beliefs. As predicted, data from telephone interviews with 271 subjects indicate that individuals knowing someone with epilepsy held significantly more accepting attitudes than respondents who had never known an epileptic. The findings also suggest that witnessing epileptic seizures is an emotionally charged event, and, in the absence of other types of experience, this emotional impact might have a negative effect on attitudes toward people with epilepsy. The findings from this study have implications for the development of educational programs aimed at the general public, medical personnel, and people with epilepsy.     

Effects of association,frequency, and stimulus quality on naming words in the presence or absence of pseudowords

According to classical dual-route theory, effects of associative priming and frequency on the naming of printed words arise from lexical access and should be weak or absent when word names are assembled prelexically. Assembled naming would be more likely in a shallow orthography, especially in the presence of nonwords. This hypothesis was examined with the shallow Serbo-Croatian orthography. Interactions between association, frequency, and stimulus quality were also examined in both Serbo-Croatian and English. Contrary to classical dual-route theory, both lexical effects were found for naming words in Serbo-Croatian, with or without nonwords. Neither interaction was significant in Serbo-Croatian and only association X quality was significant in English. Discussion focused on (a) the claim that lexical effects on naming in a shallow orthography constitute prima facie evidence against either prelexical phonology or the orthographic depth hypothesis, and (b) the possible factorization of frequency and active associative knowledge in naming words.     

Mental patients as computer operators

Tactics of design are described for programs to be used by chronic psychiatric patients on an accounting task in the maintenance of records of token economies at Creedmoor Psychiatric Center. To address the patients’ cognitive, motoric, and motivational deficiencies, special attention was paid to display features, branching formats, error detection, feedback, and keyboard utilization.     

The structure of informed consent in psychiatric research

The manner in which the informed consent process is structured was explored by means of intensive interviews with 17 experienced psychiatric researchers. Despite differing views on informed consent, investigators displayed a commonality of practice. Most investigators were themselves not usually involved in obtaining consents, relegating the process to lower-level assistants. They did not closely monitor the process and generally were unaware of problems that may have arisen. Most protocols called for repeat contact with patients so that a relationship would develop and information could be provided before obtaining a formal consent. The actual signing of a consent form often reflected a decision that had been made much earlier in the process. These findings have significance for both sides in the dispute over informed consent in research. Those who favor tighter controls over psychiatric research will have to consider the implications of monitoring, without destroying, a prolonged and complicated process. Those who argue for a reliance on investigators' integrity must deal with the apparent lack of involvement most investigators have in the consent process.     

Intelligence in Hong Kong measured for Spearman's g and the visuospatial and verbal primaries

Values for Spearman's g for Hong Kong are calculated from data derived from the administration of Raven's Standard Progressive Matrices to several thousand children. The results indicate that the mean IQ in Hong Kong for the mid 1980s is approximately 108 in relation to a Caucasian mean of 100 for the United States and the United Kingdom. Values for the spatial and perceptual speed primaries are also substantially higher in Hong Kong. On the other hand Hong Kong children are relatively weak on the word fluency primary. The pattern of abilities of Chinese Hong Kong children is broadly similar to that obtained on other Mongoloid populations.     

Disorders of attention in school children: recent results of classification, diagnosis and pedagogic-psychologic perspectives for intervention

Attention disorders in school children are a frequently occurring phenomenon in the work of clinical psychologists and psychiatrists. The new approach (DSM III) emphasizes the role of attention deficit with/without hyperactivity in contrast to the Hyperkinetics syndrome (ICD 9) and offers an alternative interpretation. Based on experimental results and clinical observation, the following characteristic features of this class of disturbances are accentuated. A deficient central activation (probably related to "weakness" of central norepinephrine and the locus for stimulant drug action), an inadequate inhibitory control function, and a (secondary) disturbance of perceptive and logic processing strategies. A method of cognitive-behavioural intervention is offered which may be applied separately of in connection with drug treatment.
