The Organization Of Function In The Delinquent, Newell C. Kephart

Proceedings of the Iowa Academy of Science

The thesis in this study was that juvenile delinquents display personality defects which may be described as disorganization of the mental data. Such disorganization is thought of as a disconnectedness between the elements of the psychic material. It is thought that delinquent subjects as a group will give evidence in performance of less dynamic dependency among these data than will non-delinquent subjects as a group.

Handedness In The First Two Years Of Life, Ruth Klein Lederer

Proceedings of the Iowa Academy of Science

A study of handedness in the first two years of life should contribute to a systematic description of the development of handedness at this period, factual information concerning which has heretofore been lacking. In this approach handedness has been defined in terms of a psychological concept and is limited to overtly discernible handed behavior.

Psychology Of The Emotions - Practical Aspects For The Teacher, E. G. Lockhart

Proceedings of the Iowa Academy of Science

Basic Facts about the Emotions:

1. The organic changes that characterize the emotional disturbance are intellectually stimulated - a crucial fact when we come to teach the control of the emotions.

Common And Differential Factors In Reading Vocabulary And Hearing Vocabulary, Irving H. Anderson, Grant Fairbanks

Proceedings of the Iowa Academy of Science

Numerous studies have shown that recognition of word meaning is closely related to reading ability. All of these studies, however, measured reading vocabulary only. This research attempts to determine how recognition of read and heard words compares, and how the two types of vocabulary are related to reading ability. Since material is held constant, but the mode of presentation is varied, this approach should make possible the study of certain common and specific elements in the abilities to recognize words read and heard, and to determine the manner in which this relationship is affected by reading ability.

The Adjustment Problems Of College Freshman And Contributory Factors, Earle E. Emme

Proceedings of the Iowa Academy of Science

There were 5,959 adjustment problems discovered from 73 freshmen.

A Genetic Study Of The Vibrato, Alan D. Grinsted

Proceedings of the Iowa Academy of Science

The question of whether or not the vibrato, which is found in the singing voice of all vocal artists and of some untrained adults, and occasionally in the speaking voice, is learned, or is due to some inborn physiological characteristic is one which has been the subject of considerable speculation. Upon this question rest the answers to such questions as these: Will there come a day when voices with vibrato will not be considered beautiful? Should the vibrato be expected to appear automatically when a student of singing learns to vocalize properly or is there a special technique to be …

A Statistical Study Of Attitudes, A. R. Lauer

Proceedings of the Iowa Academy of Science

An attitude test covering seven major attitudes, established on a priori grounds, was given to 165 adult male subjects in industrial plants. Included are attitudes toward traffic regulations and enforcement; risk and annoyance; socialistic, communistic and conventional principles; racial and religious attitudes; conformist attitudes; and those relating to sports. The reliabilities of the attitude groupings range from .86 down to .55. Intercorrelations of these items indicate grouping into a smaller number of factors. A comparison is made between accident and non-accident drivers on significant attitudes.

Stuttering In Relation To Various Speech Sounds, Wendell Johnson, Spencer F. Brown

Proceedings of the Iowa Academy of Science

Thirty-two stutterers read over 300,000 words, stuttering in relation to over 30,000 of them. Stuttering was analyzed with reference to its relative frequency in relation to specific sounds, and conclusions were drawn with reference to the problem of the precipitation of a moment of stuttering.

It is generally believed that psychology has made a significant contribution to teaching methods. Can not the psychologist he of service in determining what is to be taught as well as in determining how teaching methods can be improved?

Intensive And Durative Aspects Of The Interpretation Of A Musical Score, Arnold Small

Proceedings of the Iowa Academy of Science

The purpose of this study was to determine how closely the violinist follows the printed score in assigning temporal and intensity values to notes and to demonstrate some ways in which duration and intensity are utilized in stress and phrasing.

An Analysis Of The Berger Rhythm, With Special Reference To The Duration And Amplitude Of The Individual Wave, John R. Knott

Proceedings of the Iowa Academy of Science

The rhythmical electrical potential waves recorded from the human brain have been classified by their discoverer, Berger² into two types: alpha-waves, and beta-waves. This classification is made on the basis of the duration and amplitude of the waves. Waves having a duration of about .10 sec. and an amplitude of about 20 microvolts fall into the category of alpha-waves. Waves having a duration of about .04 sec. and an amplitude of about 10 microvolts make up the beta-waves. In general, the beta-wave is formed on the sides of the larger and more predominant alpha-wave.

A Measure Of The Amount Of Chance In True-False Tests, E. O. Finkenbinder

Proceedings of the Iowa Academy of Science

When students were informed of the number of errors they had made on a 30-point true-false test and given their answer sheets on which they crossed out and changed the answers they thought might be the ones in error, they could not significantly raise their scores (corrected for chance) when the number of true and false statements were approximately equal. If the number of true statements were greatly in excess of the false statements, say two true to one false, they lowered the score by their changes. On the other hand, if the false statements greatly outnumbered the true ones, …

Semantic Psychology, O. M. Norlie

Proceedings of the Iowa Academy of Science

Semantic psychology is the psychology of language. This paper will call attention to the need of a more psychological alphabet.

Perception Of Relations In Reading, Dan L. Adler

Proceedings of the Iowa Academy of Science

The present study deals with the measurement of intelligence on the college level by means of a new type of test employing the medium of reading comprehension. The test was first described by Dr. D. D. Feder at the 1934 meeting of this group. Basic to the new approach is the hypothesis that intelligence is manifested in the ability to perceive relationships in problem situations. In accordance with this hypothesis, individual differences in reading comprehension are due to variations in ability to perceive interrelationships of ideas in reading materials. The new reading test assumes that there are gradations of comprehension …

A Validation Of Certain Measures Of Personality Adjustment At The College Level, D. R. Mallett

Proceedings of the Iowa Academy of Science

This report deals with some preliminary data on the validity of the Bell Adjustment Inventory, a questionnaire scale designed to locate personality maladjustments in high school and college students. Other similar measurements being studied are the Thurstone Personality Schedule and the Woodworth-House Mental Hygiene Inventory.

Are There Types Of Learning And Thinking That Are Functionally Distinct, And If So, What?, Robert Leeper

Proceedings of the Iowa Academy of Science

The field covered by the concepts of learning and thinking is so extensive, and includes such a diversity of concrete material, that it would be very surprising if all could be covered by the same explanatory subject matter. If the field is heterogeneous, effective research on learning and thinking is contingent upon the classification of these materials into functionally distinct groups. Relatively little attention has been paid to this problem, however, and much of the discussion that has existed has been patently superficial (maze learning an example of "motor habits," e.g.). The present paper discusses the basis for such classificatory …

Some General And Specific Factors In Transfer Of Training, Charles Van Riper, Robert L. Milisen

Proceedings of the Iowa Academy of Science

Two groups were used, one of which was trained in a right hand clockwise, and the other in a right hand counter-clockwise direction of motor skill. The transfer to the untrained hand in both groups was greatest in the direction opposite to training, although every case improved in both directions. The improvement due to the specific training was felt to account for the higher scores in the opposite direction, the remainder being due to general transfer.

Statistical Analysis Of Change-Over Or Reversal Tests, A. E. Brandt, A. Starbuck

Proceedings of the Iowa Academy of Science

The arithemetical procedure known as the analysis of variance is offered as a method determining the reliability of a test when two forms are given to subjects of known differences in ability or determining proficiency of students when given scaled questions. Results obtained by members of the English Department of Iowa State College in the process of designing a progress test are used as an example. The students were divided into high and low groups on the basis of scores received previously on the Iowa State College aptitude test, on a theme and on the Iowa State College English Department …

The Effect Of Penalty Upon Frequency Of Stuttering Spasms, C. Van Riper

Proceedings of the Iowa Academy of Science

One of the features with which the psychologist must constantly deal when investigating stuttering is the great amount of variation in the frequency of stuttering blocks or spasms. Steer ¹ has shown that frequency of stuttering spasms is, at least to a certain degree, a function of the type of speech situation. Van Riper and Hull² showed a progressive decrease in frequency of spasms as the stutterer adapted to any given speech situation. However, little knowledge was gained from these experiments as to what factors in the situations were responsible for the variations in frequency.

Intonation In Violin Performance, Paul C. Greene

Proceedings of the Iowa Academy of Science

A controversy exists as to whether artists who play stringed instruments perform in the so-called "natural" (sometimes called the "just" or "pure") musical scale, in the "equally tempered" scale, or in some other scale. A related question is whether these artists characteristically enlarge (augment) or contract (diminish) certain intervals as compared with their theoretical scale values.

A Study Of Creative Imagination In Artistic Expression, William A. Mccloy

Proceedings of the Iowa Academy of Science

In this investigation of the nature of artistic expression, creative imagination is studied through the medium of a model stage, appreciation of colored slides, and imaginative insight by abstract paintings.

Characteristic Features Of Intellectual Deterioration In Schizophrenia And Organic Psychoses, Eleanor Palmer

Proceedings of the Iowa Academy of Science

This study compares the performance of a group of deteriorated schizophrenics and organic brain diseases on the short form of the Stanford-Binet Scale with that of a control group of subnormals grading at the same mental age. Analysis of the data reveals significant differences with respect to vocabulary level, extent of scatter, and relative difficulty of particular test items which may be described in terms of an objectively recognizable "scatter pattern."

The Adaptation And Variability Of Response Of The Human Brain, B. K. Bagchi

Proceedings of the Iowa Academy of Science

Electrical potentials have been recorded from the brain of five normal human subjects by means of needle electrodes inserted about half a centimeter through the scalp, one near the external occipital protuberance and another about three inches forward and an inch to the side from the median line. The high time-constant of the amplifier, which was about a second, made it possible to obtain an almost distortionless recording of the low frequency waves. The amplifier was connected to the oscillograph element. The oscillation of the light beam projected from the element was photographed on sensitized paper.

Preliminary Study Of Certain Changes Occurring Under Sodium Amytal, James W. Layman

Proceedings of the Iowa Academy of Science

The present report deals with a quantitative study of certain intellectual and motor changes which occur in schizophrenic patients under the influence of sodium amytal, a hypnotic drug used for therapeutic purposes with patients receiving psychiatric treatment at the Psychopathic Hospital of the State University of Iowa.

Time Characteristics In The Word-Association Test, Harold M. Williams

Proceedings of the Iowa Academy of Science

It has been repeatedly demonstrated that the word-association test empirically differentiates normals from delinquents and psychopaths, as well as a state of emotional calm from one of apprehension in a given subject. It is still relevant, however, to inquire more deeply, if possible, into the psychological nature of the process.
