Interpersonal referential communication experiments with a small computer

A LINC-8 computer is used with a Tektronix 611 CRT for presenting verbal information, and a slide projector for displaying facial photographs in studies of interpersonal referential communication.     

Monitoring experimental results

No matter whether an experiment is a success, a failure, or a mixture of the two, the E needs to see his results immediately to be able to plan his next study. For this purpose, he needs a rapid, simple, relevant analysis of the data. We define a version of this data-summarizing problem and describe a monitor program to solve it. One major decision is what search method and data file organization to use; We use the n-dimensional array method. We specify dependent variables in two parts: first, a measure code like proportion correct, reaction time, etc., and second, a series of coefficients to specify what items will make up the desired dependent measure. Our program is interactive and makes extensive use of default options. Some suggestions are made for the implementation of monitor programs on other hardware.     

Developmental changes in apportionment of study time among items in a multitrial free recall task

First grade, third grade, and college Ss attempted to memorize a single set of items over the course of 5 trials, each trial consisting of a 45-sec study period followed by a free recall test. On all trials but the first, S was allowed to have available during his study period only half of the total set of items, but was free to select whichever items he wished to include in this half. Third grade and college Ss were significantly more prone than first grade Ss to select for study items not recalled in the immediately preceding recall test. The results suggest that the strategy of deliberately concentrating one's study activities on the less well mastered segments of materials to be learned, like other elementary memory strategies (e.g., rote rehearsal), cannot automatically be assumed to be part of a young child's repertoire of learning techniques.     

Psychosynthesis: A psychotherapist's personal overview

Psychosynthesis, a therapeutic orientation based on personal experience, bridges psychological and theological conceptions of human nature. Psychotherapy is conducted in the here-and-now with emphasis on the relationship. Within that context, many techniques are employed. Imagination and intuition are cultivated. The client is helped to identify with his personal self, the center of consciousness and will, and to exercise willing control over the process of therapy and over his life. Basic principles include the existence of a higher unconscious, which is the locus of transpersonal needs, the interrelatedness of one to all, the reality of consciousness and will. Positive strivings and continuing growth are emphasized.Dr. Haronian is in private practice     

A second-generation motor rhythm analysis system

This report describes the design and operation of a second-generation motor rhythm analysis system (MRAS). The system enables quantification of spatial and temporal characteristics of movements performed in synchronization with audio-visual rhythmic stimuli. The MRAS also provides for assessment of preferred tempo in performance of repetitive movements. In addition to discussing the rationale for developing the system, consideration is given to procedures for its utilization in research regarding motor rhythm and preferred tempo.     

The duration and generalization of attraction

Tested in the present study were the propositions that attraction toward others is lasting and that liked and disliked individuals serve as a basis for liking others. On the first day, subjects received interpersonal evaluations (e.g., judging the intelligence of others) which supposedly had originated with an anonymous person. Following a delay of 1 to 3 days, the attraction of some of the subjects toward the anonymous person was assessed while the attraction of other subjects toward a second anonymous person, who presumably had also evaluated the subjects, was also assessed. These latter subjects were never exposed to the alleged evaluation by the second person. Attraction toward the first person tended to endure and to generalize to the second person.     

Need for affiliation and sex as moderators of the relationship between need for achievement and academic performance

Sex and need for affiliation (n Aff) were investigated as potential moderators of the association between need for achievement (n Ach) and academic performance. Measures of n Ach and n Aff, based on the Personality Research form, were obtained or 78 male and 114 female grade 11 students. On the assumption of a conflict between n Ach and n Aff, it was hypothesized that high n Ach, low n Aff students earn higher grades than high n Afh, high n Aff students. The results for both males and females supported the hypothesis. Evidence was available which suggested that the poorer academic performance of the high n Ach, high n Aff students was due to an inability to maintain effectively their attention while studying. The results also indicated that, relative to other students, high n Ach females displayed a markedly superior academic orientation. Attention was drawn to the fact that the formance of the high n Ach girls appears incconsistent with some current theorizing regarding the achievement orientation of females.     

Relative efficacy of two token economy procedures for decreasing the disruptive classroom behavior of retarded children

Numerous studies have demonstrated that disruptive classroom behavior can be decreased by delivering tokens contingent upon periods of time during which children do not engage in it or by removing tokens contingent upon its occurrence. To date, the best controlled of these studies have consistently reported the two procedures to be equally effective. However, in these studies, token contingencies have been combined with instructions regarding the contingencies. The present study compared these two procedures when no instructions were given regarding the token contingencies. Token delivery was not effective in decreasing disruptive behavior in any of the children, while a combination of token delivery and removal was effective for three of four children. The results suggest that the combined procedure may be effective with certain populations that are not readily controlled by instructions.     

Size of the Mueller-Lyer illusion as a function of its dimensions: Theory and data

In tests with naive subjects, it was found that: the apparent length of a test shaft (1) increases with angle of wing to shaft to a maximum of about 160° (wings out), and (2) is an inverted-U function of wing length, with maximum when wing length equals shaft length; (3) all effects are approximately proportional to shaft length; and (4) the angle exerts its effect within a small region near the tip of the shaft, the region extending about one-seventh the shaft length. The effects apparently do not result from simple distortion of the retinal image, but some may result from assimilation or confusion in coding image into lengths, and some effects apparently arise as lengths are combined into judgments. The new data are shown to agree in quantitative detail with results collected from 1896 to the present.     

THE PAINS OF R-GEORGE,ROBOT

In this essay I wish to raise the question of whether it is meaningful to say that a certain sort of robot is in pain. This is, of course, not an empirical question. There exists no robot of the sort I shall describe. But, I shall argue, if such a robot did in fact exist, it would be meaningful to say it is in pain.
