Consultee-centered consultation with a teacher as a technique in behavior management

Client-centered consultation was effective in helping a teacher to decrease one child's disruptive classroom behavior, and consultee-centered consultation helped the teacher improve her control of the class as a whole. Initially, a client-centered reinforcement program effectively decreased the disruptive behavior of one target child. Later, attention to the teacher's feelings about being the authority figure in the classroom was used in an attempt to modify the behavior of the entire class. The data describing the behavior of a second child in the classroom suggested that this consultee-centered consultation was followed by less classroom disruption. In addition, anecdotal observations indicated that consultee-centered consultation was effective in modifying the behavior of both the teacher and the rest of the class.     

On the independence of judged frequencies for items presented in successive lists*

In an experiment examining retroactive interference effects in a frequency-judging task, all Ss were presented with a list of words occurring varying numbers of times according to either a massed- or distributed-practive (MP or DP) schedule. They were then asked to judge how often each word had occurred. Following this, Ss were given one of four types of second tasks a second list with different items followed by a frequency-judging task for that list (Condition New): a second list with items repeated from the first list but with different frequencies for each item, while either maintaining items as either MP or DP items (Condition Same) or switching MP items to DP, and vice versa (Condition Reverse): followed by a frequency-judging task for the second-list frequencies only: or a puzzle task for the amount of time required for second-list presentation and judgment in the other conditions (Condition None). Finally, all Ss were asked to recall List 1 frequencies, List 2 frequencies were less discriminable in Conditions Same and Reverse than in Condition New. Recall of List 1 frequencies, however, was not different for these three groups, but was poorer than in List 2 frequency judgments were not independent of List 1 frequencies.     

The “Clean for Gene” Phenomenon: The Effect of Students' Appearance on Political Campaigning1

Field experiments investigated the relationship between a political campaigner's dress and appearance and his campaign effectiveness. In one study deviant, “freaky” appearing campaigners attempting to hand out innocuous leaflets in a shopping center had a lower acceptance rate than did more conventionally dressed campaigners. Those shoppers who did accept leaflets from “freaks” were more likely to throw them away unread. The first experiment suggested that deviant-appearing campaigners have difficulty communicating information to potential voters, but it was argued that, in another sense, they convey all too much information. Knowing only that the campaigners for one candidate were deviant and “hippy” in appearance as compared to the conventionally dressed campaigners supporting a second candidate, voters in a second experiment were willing to ascribe more radical opinions to the deviants' candidate. Voters then used their inferences as the basis on which to select a candidate. The rationality of inferring beliefs from appearances is discussed in terms of correspondent inference theory.     

The effect of memory load on the right ear advantage in dichotic listening

The right ear advantage (REA) observed in dichotic tests was further investigated to examine the effects of memory load on the task. Memory load was operationally defined as the duration of time wherein subjects were asked to retain the stimuli, with no rehearsal, prior to recall. The delay periods interpolated between dichotic stimulation and recall were: no delay, 5, 10, and 15 sec delay. There was a significant REA in the no delay condition. The conditions with interpolated delay periods showed a substantial loss in overall accuracy, and at 15 sec delay showed a strong REA. The results offer suggestive evidence for a lateralized memory mechanism for storing speech sounds.     

Discrimination learning as a function of differences in materials: A proposed explanation

The present study affords an explanation for the consistent, but not always statistically significant, pattern showing superior verbal discrimination learning performance for low- as compared to high-frequency words. In a frequency judgment task, it was found that relative to high-frequency words, low-frequency words for which Ss (sixth graders) knew the meanings produced apparent frequency measures consistent with superior verbal discrimination learning, while low-frequency words that were unknown to the children did not. These results, taken together with those based on comparisons of pictures and high-frequency words, lend themselves to a modified Weber’s law interpretation of stimulus material differences in discrimination learning.     

An empirical verification of the Wherry-Gaylord iterative factor analysis procedure

A comparison of the Wherry-Gaylord iterative factor analysis procedure and the Thurstone multiple-group analysis of sub-tests shows that the two methods result in the same factors. The Wherry-Gaylord method has the advantage of giving factor loadings for items. The number of iterations needed can be reduced by doing a factor analysis of sub-tests, re-grouping sub-tests according to factors, and using each group as a starting point for iterations.This research was carried out under Contract No. WSW-2503, between the Department of the Army and Ohio State University. This paper is based on the final report PRS No. 827 under that contract. The opinions expressed herein regarding matters relating to the Department of the Army are those of the authors and are not necessarily official.     

Factor analysis of the army air forces sheppard field battery of experimental aptitude tests

A factor analysis was made of 39 experimental printed aptitude tests and seven reference tests selected from the Army Air Forces Aircrew Classification Battery. Thirteen factors were extracted and two independent orthogonal rotational solutions were completed. Twelve factors were interpreted. Of these, seven were clearly identifiable with previously known factors: numerical, perceptual-speed, spatial-relations, visualization, visual-memory, paired-associates-memory, and length-estimation factors. A planning factor was not as clearly identifiable. A reasoning factor was probably a composite of two or more factors that failed to separate. A new factor possibly has to do with orientation with respect to the points of the compass. Two factors were doublets, each apparently specific to one kind of test. Better conceptions were gained of the spatial-relations and visualization factors and of the kinds of tests that measure them best. Efforts to improve measures of unique factors were not uniformly successful. The attempt to duplicate a psychomotor test rather directly by analogy in printed form failed almost completely.For support of a large part of the investigation the senior author is indebted to the Social Sciences Research Council for a grant-in-aid. Dr. Fruchter supervised the computational work in the extraction of factors and in one of the rotational solutions. Much of the work was done while he was employed by the Air Training Command Human Resources Research Center. While the opinions and conclusions are those of the authors, they wish to express their appreciation to that organization and especially to Dr. John T. Dailey for making the facilities possible and to Mr. William B. Lecznar for technical and computational assistance.     

A simple graphical method for orthogonal rotation of axes

A simple method of making orthogonal rotations by projecting coordinates from one plot to another is presented. An easily constructed apparatus for rapid and accurate work is described in detail. By the technique proposed 12 to 15 rotations of pairs of axes involving 20 test variables can be completed per hour by a practiced technician.     

Some notes on time out from reinforcement

Pigeons produced food on a fixed-ratio schedule by pecking at one key, and an S^Δ period by pecking at a second (switching) key. Switching behavior was examined as a function of (a) size of the fixed ratio, (b) whether the S^Δ was of fixed duration or could be determined by the bird, (c) the introduction of a novel food S^D, (d) extinction of food responding, and (e) the stimuli associated with the S^D and S^Δ conditions. No monotonic relationship was obtained between ratio size and switching behavior. Switching behavior was, however, influenced by many variables. The results suggest that an interpretation of switching behavior in terms of its being reinforced by the removal of aversive conditions, is open to considerable question.
