Relation Of The Fritz-Neidt Practical Policy Test To Freshman: Entrance Tests, Martin F. Fritz
Relation Of The Fritz-Neidt Practical Policy Test To Freshman: Entrance Tests, Martin F. Fritz
Proceedings of the Iowa Academy of Science
Previous investigations, reported to the Psychology Section of the Iowa Academy of Science, have been concerned with the development of a test designed to measure cynicism and idealism. Since the nature of the items used, the theory of the construction, the manner of administration, and the method of scoring have already been described (see references), no attempt will be made to consider these details in this paper.
Development Of A Test Of Aptitude For Veterinary Medicine, William A. Owens
Development Of A Test Of Aptitude For Veterinary Medicine, William A. Owens
Proceedings of the Iowa Academy of Science
Particularly since the war, schools of veterinary medicine have been able to enroll for training only a relatively small percentage of their applicants. An increased emphasis upon the importance of identifying the best qualified candidates has resulted in a careful reexamination of selection procedures and in recognition of the possible utilization of some sort of veterinary aptitude test.
Reliability Of The O'Connor Block Test, Richard H. Bunch, R. N. Kjerland, A. R. Lauer
Reliability Of The O'Connor Block Test, Richard H. Bunch, R. N. Kjerland, A. R. Lauer
Proceedings of the Iowa Academy of Science
The O'Connor Block test is widely known and is manufactured and sold without any very definite information as to its reliability and validity. In fact it seems to be used without great uniformity in method of administration. Whenever mechanical ability is discussed one is likely to hear of this test along with several others. No published studies of the O'Connor Block test of any great importance have been made on its relative merits and its reliability and validity. Several years ago exploratory studies on this test, along with others designed to measure mechanical aptitude and ingenuity, were conducted in the …

Motor Responses As A Function Of Type Of Conflict, Burton G. Andreas
Motor Responses As A Function Of Type Of Conflict, Burton G. Andreas
Proceedings of the Iowa Academy of Science
In his introduction to a discussion of experimental studies of conflict, Neal E. Miller (2) states that "conflict is produced by competition between incompatible responses." He goes on to say, however, that such response phenomena as hesitation, vacillation, or complete blocking are not found in all situations where there are competing response tendencies. The extent to which they appear is a function of the type of conflict situation. Using human subjects in a series of experiments on motor conflict, Hovland and Sears (1) confirmed this prediction from theory. These investigators studied the effects of two types of conflict - double-approach …
Some Recent Changes In Rural Living Which Have Psychological Implications, William H. Dreier
Some Recent Changes In Rural Living Which Have Psychological Implications, William H. Dreier
Proceedings of the Iowa Academy of Science
Eric Johnston, president of the Motion Picture Association of America told the American Farm Bureau Federation in Chicago last December, "A few years ago our Department of Agriculture entitled its yearbook, 'Farmers in a Changing World.' That was a good title, but I think a better one would have been 'A World of Changing Farmers.'" As teachers and instructors of students from rural communities we are part of this world of changing farmers here in the United States. Since the time and example of the Master Teacher, Jesus Christ, the best teachers have known about the environment in which they …
Factorial Study Of Speed Of Response In Simple Cancellation Tasks, Dale W. Dysinger
Factorial Study Of Speed Of Response In Simple Cancellation Tasks, Dale W. Dysinger
Proceedings of the Iowa Academy of Science
Several factor analyses have been conducted with the objective of isolating the aspects of the stimulus situation affecting performance on simple tasks presented under the set for speed as well as accuracy. The factors in this area of performance have not proved to be as stable as have some in the areas of verbal, spatial, and numerical skills. In a recent factor analysis, [1], several new hypotheses were presented to account for the apparent instability of the perceptual-speed domain. One of these hypotheses was that three or more linearly independent factors must be postulated to account for the variance of …
An Empirical Study Of Scoring Methods For The Conover Driving Attitude Inventory, T. E. Hannum, Gerald C. Helmstadter, A. R. Lauer, David H. Soule
An Empirical Study Of Scoring Methods For The Conover Driving Attitude Inventory, T. E. Hannum, Gerald C. Helmstadter, A. R. Lauer, David H. Soule
Proceedings of the Iowa Academy of Science
The measurement of driving attitudes has followed in the wake of various studies and statistical data indicating that improper attitudes are responsible for an unduly high percentage of accidents. Certain of these tests have limitations, one of which is an economical method of scoring. Conover (Conover, 1947) used a scoring method such that the values 0, 1, 2, 3, 4, are assigned respectively to the responses designated as; most displeasing, displeasing, indifferent, pleasing, and most pleasing, for the positive items, and to avoid negative scores the values 4, 3, 2, 1, 0, are assigned respectively to the same responses; most …
A Method For Measurement Of Perceptual Time On The Highway, Donald A. Hoppe
A Method For Measurement Of Perceptual Time On The Highway, Donald A. Hoppe
Proceedings of the Iowa Academy of Science
A major handicap for studies of perceptual time on the highway has been the lack of an adequate means of simultaneously starting a chronoscope and exposing a highway situation to a subject. The problem is better appreciated when it is realized that on the one hand the subject's vision must be restricted from the situation to be exposed. On the other hand he must be permitted to view the road for a certain distance ahead of the car. The latter is necessary to allow for adjustment of the eyes to the existing level of illumination and for adaptation of the …
A Forced-Choice Rating Scale For College Instructors, A. R. Rustebakke, George D. Lovell, Charles F. Haner
A Forced-Choice Rating Scale For College Instructors, A. R. Rustebakke, George D. Lovell, Charles F. Haner
Proceedings of the Iowa Academy of Science
The purpose of this study was to construct a forced-choice rating scale for evaluating students' opinions of college instructors. The scale constructed consists of 20 tetrads, or groups of 4 statements descriptive of instructors. These statements were chosen so that a pair of favorable items, both appearing to be equally favorable, and a pair of unfavorable items, both appearing to be equally unfavorable, make up each tetrad. From each tetrad the rater must choose the item most characteristic and the item least characteristic of the ratee. The reason for choosing items in this manner can be seen in Sisson's statement …
"Single-Trial-Per-Task" Versus "Multiple-Trials-Per-Task" In The Acquisition Of Skill In Performing Several Similar Tasks, Dorothy E. Mcallister
"Single-Trial-Per-Task" Versus "Multiple-Trials-Per-Task" In The Acquisition Of Skill In Performing Several Similar Tasks, Dorothy E. Mcallister
Proceedings of the Iowa Academy of Science
The present experiment was an attempt to discover the relative merits of two different practice procedures in developing skill in the performance of psychomotor tasks. Specifically, the aim was to determine whether one trial per day on each of eight different but similar tasks for eight consecutive days would result in better performance on a. test task than would eight trials per day for eight consecutive days each involving a different but similar task.
An Apparatus To Mleasure Reaction Time Under Mobile Conditions By Radio Control, Reginald N. Kjerland, A. R. Lauer
An Apparatus To Mleasure Reaction Time Under Mobile Conditions By Radio Control, Reginald N. Kjerland, A. R. Lauer
Proceedings of the Iowa Academy of Science
Certain types of studies of driving performance require mobile equipment for use in making objective measurements of behavior under actual traffic conditions. Due to the inherent dangers of stationary apparatus being used on the highway it becomes important that satisfactory portable and mobile equipment be used to facilitate objective measurements of drivers in traffic, highway and driving research.
Effect Of Shock On Performance In A Paired-Associate Learning Task, Eli Saltz
Effect Of Shock On Performance In A Paired-Associate Learning Task, Eli Saltz
Proceedings of the Iowa Academy of Science
Hullian psychology conceptualizes the effects of noxious stimulation as drive producing and the effects of removal of such stimulation as a rewarding state of affairs (3). These effects have been repeatedly demonstrated in situations where they have facilitated learning (2, 4). It is obvious, however, that increased drive need not necessarily aid learning, and it may at times hinder it. The present study is concerned with the consequences for learning when electric shock is introduced at the same time as the stimulus word and is removed when the response word is spoken in paired-associate learning. The study is particularly interested …

Homogeneity Of Behavior Indicated From The Spearman-Brown Prophecy Formula, Charles O. Neidt
Homogeneity Of Behavior Indicated From The Spearman-Brown Prophecy Formula, Charles O. Neidt
Proceedings of the Iowa Academy of Science
The reliability of a test is usually defined as the consistency with which a test measures whatever it measures, the consistency being indicated by the correlation between two administrations of the same test or between equivalent forms. Whenever it has not been feasible to administer the test twice, or whenever full-length equivalent forms have not been available, the procedure usually followed has been that of making two synthetic tests by scoring the odd- and even-numbered items separately, or by scoring two randomly-drawn lists of items. Dividing the test in this manner results in obtaining a correlation between two forms which …
The Concept Of Attitude, Dale Ortmeyer
The Concept Of Attitude, Dale Ortmeyer
Proceedings of the Iowa Academy of Science
The concept of attitude in psychological and social psychological literature has a variety of interpretations and meanings. In the past few decades, the quantification of attitude measurement has been an area of experimental investigation. Measurement of any phenomenon pre-supposes a proper definition and an analysis of the concept under consideration. The present study is an approach to the clarification of the concept, preparatory to an experimental attack in the area of psychosociological measurement of attitudes. Contributions by men in the various schools of psychology are presented with emphasis placed upon the behavioristic point of view. Delimitation of the concept and …
Projecting Introductory Psychology Examinations At Iowa State College, Ross R. Thomas
Projecting Introductory Psychology Examinations At Iowa State College, Ross R. Thomas
Proceedings of the Iowa Academy of Science
During the fall quarter of 1948 examinations in the introductory Psychology course at Iowa State College were first administered by slide projection. Results of this procedure were considered satisfactory and this method of administration has been continued. The primary reason for utilizing this method was to maintain the security of the examination material. Test slides were prepared in the departmental office, lessening the possibility of students obtaining tests prior to examination date. In addition, all test items were thus subject to independent use, further decreasing opportunities of procuring information as to examination content. Secondary reasons for the procedure were: (1) …

Effect Of So-Called Night-Driving Glasses On Visual Acuity - A Preliminary Study, A. R. Lauer, Edwin D. Fletcher, Paul Winston
Effect Of So-Called Night-Driving Glasses On Visual Acuity - A Preliminary Study, A. R. Lauer, Edwin D. Fletcher, Paul Winston
Proceedings of the Iowa Academy of Science
Evidence from various studies such as those of Cobb ( 1914), Ferree and Rand (1923), Fry and Bartley (1933), Hecht (193S), Graham and Cook (1937), Bartley (1941) and more recently by Lauer and Silver (194S) and others have indicated that brightness contrast, as a function of stimulus illumination and consequent retinal stimulation, is one of the basic factors in visual acuity. It is a safe assertion that seeing efficiency and acuity are closely related, up to a certain level of illumination. At higher levels of illumination this perhaps does not hold. In certain quarters an opinion persists that filters which …
The Social Responsibility Of The Teacher Of Science, Joseph B. Gittler
The Social Responsibility Of The Teacher Of Science, Joseph B. Gittler
Proceedings of the Iowa Academy of Science
It is the contention of this paper that facts of science (natural science) are being taught superlatively well by science teachers, but that the spirit of science - the logic and philosophy of science, science as an intellectual pursuit - tends to evade the domain of the science teacher. Furthermore, it is this failure to inculcate in the student this spirit of science - the scientific mentality - that accounts for some of the gravest ills in our society. If it is true that most of society's problems are man-made (and it can be shown without difficulty that they are …
