A four-test short form of the WISC-R

A four-test short form of the WISC-R was developed on the basis of both rational and statistical criteria, using data from the representative standardization sample. The short-form comprised Arithmetic and Vocabulary from the Verbal Scale along with Picture Arrangement and Block Design from the Performance Scale. Various psychometric properties of the abbreviated battery were defined, and indicators of the short form's accuracy in predicting Full-Scale IQ (the standard error of estimate, effectiveness in classifying a child's intelligence level) were provided. A major topic of discussion was the use and abuse of short forms.     

Teaching experience and teachers' expectations for grades in academic subject areas

Seventy-nine subjects who had less than 1, 2, to 3, and more than 3 years of teaching experience were given either a favorable, neutral, or unfavorable fictitious psychological report to read, describing a kindergarten child. Subjects then watched a 5-year-old child in a videotaped testing session. Expectancies toward the child were evaluated using report card grades the subjects expected the child to receive at the end of first grade. A multivariate analysis of variance with five subject area grades as the dependent variables revealed significant multivariate main effects for experience and psychological report. Significant univariate interactions in science and social studies, and social and emotional development suggested that teachers with more than 3 years of experience may have reduced susceptibility to biasing influences in psychological reports.     

The effect of sensory modalities on learning

As the importance of modalities to learning becomes increasingly apparent, the dearth of modality tests and assessment techniques becomes a critical problem. A classroom model for assessing modality strengths is suggested in which students learn to spell nonsense words via six different modalities: visual, auditory, audiovisual, vocal, motor, and tactile. The technique was used and proven effective in a study involving 396 eighth-grade students. Results of the study indicated that the presentation modality did significantly affect the amount of information learned (F = 12.36, p < .01), and that the auditory and visual modalities were most effective for this particular learning task. It is felt that this assessment technique can facilitate application of modality theory in classroom teaching.     

On the relevance of signal detection theory to the correction for guessing

This paper shows how alternatives to the conventional guessing correction may be derived from considerations similar to the signal detection theory of psychophysics. Methods of experimentally determining the right correction are briefly suggested.     

Life goals and academic interests as predictors of extracurricular activities of secondary school sophomores

The life goals and interests of eighth-graders were examined in relation to their reported extracurricular activities in secondary school. In 1969, 204 females and 178 males, attending three feeder schools, completed the Vocational Sentence Completion Blank, a semiprojective measure of life goals, values, quests, aspirations hopes, preferences, and concerns. For the Milwaukee Academic Interest Inventory, which measures curricular interests, the complete test records of 183 females and 150 males were available. In 1971, all subjects reported about their participation in six secondary school activities. Approximately two-thirds of the 29 VSCB categories and all 7 MAII variables were predictive at a low level of association. The statistically significant relations between eighth-grade predictors and specific extracurricular activities in the first year of secondary school seemed reasonable. Implications for adolescent development were discussed.     

Phonemic segmentation and blending skills of kindergarten children: Implications for beginning reading acquisition

This study explored the abilities of kindergarten children in segmenting and blending phonemic components of words and the relationship of these abilities to beginning reading acquisition measured by the word recognition subtest of the Wide Range Achievement Test (WRAT) and to auditory discrimination defined by performance on the Wepman Test of Auditory Discrimination. Random assignment of 103 kindergarten children to six experimental groups was used to evaluate phonemic segmentation and blending skills and to one control group to assess the relationship of these skills to auditory discrimination. Each experimental group received training in one of three types of word division (either C-V-C, CV-C or C-VC) for phonemic segmentation and blending in one of two task sequences (either blending first or segmentation first). Results indicate that segmentation is significantly more difficult than blending and that C-V-C is the most difficult of the three types of word division for both segmentation and blending. There were no significant differential effects of the training and control procedures on a pretest and posttest of the Wepman. Follow-up with the WRAT 1 year later indicated that C-V-C segmentation is a highly useful predictor of beginning reading acquisition. Implications for teaching of reading and for the interpretation of Wepman results are included.     

The effects of written attempts prior to correct visual presentation on spelling acquisition and retention

Students learned difficult spelling words via three different teaching methods. They either saw the correct spelling before attempting it, or could attempt to spell the word once, or several times, prior to viewing the correct spelling. Results showed that attempting to spell and test the words before viewing them facilitated acquisition of the words. The teaching methods did not differentially influence long-term retention. The locus of the effects of some teaching methods, when the words are thoroughly learned, is to be found during initial acquisition rather than evidenced in retention. Asking students to generate and test spellings prior to correct presentation facilitates encoding and acquisition of the correct spelling.     

Whiplash shaking syndrome: retinal hemorrhages and computerized axial tomography of the brain

Three cases of whiplash shaking injury of infants are presented. All children presented with seizures and had minimal signs of external injury. Examination of the retina revealed extensive retinal hemorrhages. These were missed on initial examination and were only discovered after pupillary dilatation. The presence of these palecentered retinal hemorrhages suggested the diagnosis of child abuse and skeletal surveys and thorough social histories confirmed the diagnosis. Despite extensive retinal hemorrhages, computerized axial tomography (C.T.) scan showed minimal inter-hemispheric bleeding. In contrast to the "Battered Child Syndrome," all the findings in whiplash shaking syndrome of infants are subtle and demand an awareness, an index of suspicion and a thorough examination which may include extensive retinal examination following dilatation of the pupils. This latter examination is frequently not performed by family physicians and residents so that the syndrome may be missed. A fourth case is also discussed where shaking is admitted on initial presentation but said to be done for resuscitation. This poses an immense diagnostic dilemma to the pediatrician since in this case the child presented later with all the signs of physical abuse.     

Understanding of proportion as embodied in the concept of fullness: An investigation into Bruner's “modes-of-representation-conflict hypothesis”

The present study replicates and extends an experiment by Bruner and Kenney (Bruner, J. S. American Psychologist, 1964, 19, 1–15; Beyond the information given, NY: Allen & Unwin, 1973;Bruner, J. S., Olver, R. R., & Greenfield, P. M. et al. (Eds.), Studies in cognitive growth, NY: Wiley, 1966). Children aged 5 to 11 were shown pairs of glasses containing water and were asked if one glass of each pair was fuller or emptier and to give the reason. Children aged 12 to 15 and adult subjects were subsequently included but asked to judge only fullness.The glasses differed in height, diameter, and water level and consequently in volume of water and volume of unfilled space, and in proportion full and proportion empty.It is shown that the Bruner experiment reveals weaknesses in design and procedure and focuses on the dichotomous sense of fullness rather than the partial dimension explored in the present study. Contrary to earlier findings the present results indicate that the child tends to think of fullness and emptiness in the same manner and that, far from the concept being mastered at age 11, it is still not completely understood in adulthood.By 11 years the child can cope with fractions and compare volumes, but at age 15 and in adulthood he is still not fully aware that he must not only estimate the volume of the container that is filled but also relate this volume to the total volume of the container and finally compare the two ratio measures obtained.The results are discussed in terms of Bruner's representation-conflict hypothesis, Clark's (Journal of Verbal Learning and Verbal Behvaior, 1971, 10, 266–275; Semantic development in language acquisition.
