Experimental analysis of pedophilia

It was hypothesized that the population of pedophiles differs from that of males who prefer physically mature partners, in respect of the proportion of bisexual members in each group. Bisexuality was assessed by means of a verbal scale and by recording penile volume changes during the presentation of movie clips of nude males and females. Results supported the hypothesis.An earlier finding of a difference between pedophiles and males who prefer physically mature partners, in respect to feminine gender identity, was retested using the Feminine Gender Identity Scale (for males). It could be confirmed only for homosexual males and therefore cannot be accepted as a general difference between pedophiles and persons who prefer physically mature partners.     

Vocal changes in stutterers and nonstutterers during monotoned speech

For years, reports have circulated that stutterers experience marked decrements in their stuttering when they speak or read in monotone. Wingate has suggested that the ameliorative effects of various novel speaking conditions on stuttering can be attributed to modifications in vocalization induced by such conditions. The present study was conducted to see whether this explanation would extend to monotoned speech as well. Ten teenage and adult stutterers and 10 normal speakers were tested in control and monotone reading conditions. Dependent measures were the frequencies of disfluency and stuttering, fundamental frequency, fundamental frequency standard deviation, vocal SPL, vocal SPL standard deviation, and fluent reading rate. Only within-group statistical comparisons were made, because members of the two groups could not be matched pairwise along critical vocal parameters. The major findings of this study indicated that across the two conditions, both groups significantly reduced their fundamental frequency, fundamental frequency standard deviation, vocal SPL and vocal SPL standard deviation. Only the stutterers exhibited a significant decrement in disfluency and stuttering. The normals did not evince enough disfluency in the control condition for a reduction to occur during monotoning. Neither group effected a reduction in fluent reading rates. These and other findings and interpretations are discussed relative to Wingate's modified vocalization hypothesis.     

The goal structure of situations

An empirical method for analysing the goal structure within and between persons in different social situations is described. The method involves establishing the main goals of occupants of situational roles and then finding out how the different goals inter-relate in terms of degree and type/direction of conflict and compatibility. Principal components analyses were carried out on ratings of importance of goals of those in different situational roles. Criteria of high factor loadings combined with high mean importance ratings were used to produce the main higher order goals for each of the roles. The goals for the six roles studied were, in each case except one: social acceptance/developing relationships, own well being and achieving a specific situational task goal. However, the precise nature of these goals is rather different in the different situations. Inter-relationship of goals was studied using ratings of conflict or compatibility between pairs of goals within and across roles of each situation. The results were used to describe the goal structures of the different situations. The situation with the most conflict between goals was, as expected, the complaint. Ways were suggested in which knowledge of the goal structure, particularly the points of conflict, could help with skilful handling of potentially difficult social situations.     

The role of loudness in auditory imagery

Four experiments studied characteristics of auditory images initiated by named but unheard sounds. The sounds varied in their loudness ratings. As the difference between the loudness ratings of the two sound phrases increased, the times to mentally equate the loudness of the two images increased, whereas the times to identify the louder (or softer) of the images decreased. Moreover, congruity effects were found in the comparative judgment task: Times were faster to identify the louder of two loud-rated stimuli than to judge the softer of the same two stimuli, and times were faster to identify the softer of the two soft-rated than two loud-rated stimuli. The loudness ratings did not always influence performance, however, for neither an image generation nor a reading task showed response times that varied with loudness ratings. These results suggest that sensory/perceptual components are optionally represented in auditory images. These components are included when appropriate to a given task. A control experiment showed that the results cannot be considered epiphenomenal.     

Projecting pastoral care in revival preaching: Billy Graham

Conclusion How may the evangelist project pastoral care in his preaching? This discussion sought to delineate some of the answers to this question. However, these cannot become answers for any herald of the Gospel unless he exercises an honest, sustained, self-critical probe into the inter-relatedness of his own being, attitudes toward congregants, and preaching. Erich Fromm asserts: There is no concept of man in which I myself am not included.²⁹ Likewise, there is no discussion of preaching or of a preacher in which each minister should not include himself-self-evaluatively, perhaps confessionally.     

FOCAL,FORTRAN, and BASIC programs for reformatting and analyzing data collected by the SKED program

Several programs have been written in the FOCAL, FORTRAN, and BASIC languages for reformatting and analyzing SKED data. These programs include selection and explicit labeling of sets of recording counters representing distributions and/or total counts of events, several general manipulations of distributional data, and standard statistical treatment of distributions.     

Visual proprioceptive control of standing in human infants

Human infants learning to stand use visual proprioceptive information about body sway in order to maintain stable posture. Moreover, the visual proprioceptive information is more potent than the nonvisual. This is shown by an experiment in which infants were caused to sway and even fall forward or backward in response to appropriate visual stimulation.     

Second-order schedules with fixed-ratio components: variation of component size

Key pecking by pigeons was reinforced with food under second-order schedules with fixed-ratio units. A constant total number of key pecks was required for reinforcement under each condition, but the size and, inversely, number of fixed-ratio components were varied. The total response requirement of 256 pecks was divided into fixed-ratio units of 128, 64, 32, 8, and 2 responses. A brief stimulus, which always preceded food reinforcement, was presented upon completion of each fixed-ratio unit. Under most conditions, the pattern of within-unit responding was typical of that under simple fixed-ratio schedules. Overall response rate was an inverted U-shaped function of component size. That is, response rates were highest under moderate sized units (fixed ratio 128 and 64). This relationship is consistent with previous determinations of rate as a function of fixed-ratio value for simple fixed-ratio schedules.     

Binocular stereopsis without spatial disparity

Binocular stereopsis has traditionally been studied mainly under static viewing conditions. There has consequently been the tendency to view binocular stereopsis only in terms of the pickup of purely spatial (time-frozen) disparity. However, whenever there is movement of objects or the 0, the structure of the light entering each eye undergoes continuous change, and so a different type of disparity—kinetic disparity—is made potentially available to the binocular system. That kinetic disparity can, in fact, be picked up is shown by the present experiment, in which there was no spatial disparity information available about the three-dimensional motion path of an object; only kinetic disparity information was available. This suggests that a clear distinction should be made between binocular-static and binocular-kinetic space perception.     

Overtraining and goal approach strategies in discrimination reversal

An analysis of perseverative responding, position habits, and running speed in two experiments on Y-maze reversal learning is presented. These behaviours are described in terms of different goal approaching strategies in overtrained and mastery trained rats. Analysis of such strategies and other behaviour acquired during overtraining is applied to the problem of conflicting data and apparatus differences in the study of reversal and transfer learning.
