I do no know the study to which you refer. There are about 20 items by A. Jenness and two by M.B. Jenness listed in PsycInfo between 1925 and 1945. I have copied them below (Apologies for the poor formating.) Perhaps you will find the exact ref. among these:

TITLE Ratings of vividness of imagery in the waking state compared with reports of somnambulism. ABSTRACT An analysis of the answers of 1808 college freshmen on the Thurstone Personality Inventory to the questions "Do you ever talk in your sleep?" and "Do you ever walk in your sleep?" showed that 60% do neither, 27% admit talking, and 5%, walking, the latter nearly all report talking as well. On the basis of personal reports from somnambulists and evidence from the literature, an hypothesis which emphasizes the strong kinaesthetic imagery of somnambulsits was developed. In order to test this hypotheses 138 students were asked to rate the vividness of their imagery in response to 50 words read by the instructor and to answer the 2 questions from the Thurstone questionnaire. 12 O's reported walking in their sleep, 34, talking only; these 46 tended to rate their waking imagery as more vivid than did non-somnambulists in all modalities, the differences being most significant in the visual, auditory, and kinaesthetic categories. This supports the proposed hypothesis, but more evidence is needed. (PsycINFO Database Record (c) 2002 APA, all rights reserved) AUTHOR Jenness, A.; Jorgensen, A. P.

TITLE Salivary secretion during hypnosis. ABSTRACT Secretion from Stenson's duct in response to stimulation of one cubic centimeter of lemon juice was measured in seven hypnotizable subjects during four periods of hypnosis and during an equal number of control periods in the normal waking state. Two persons whom the experimenters were unable to hypnotize, but who simulated hypnosis upon request, were similarly tested. The results are summarized as follows: (1) The average secretion for the seven subjects during hypnosis was 40% less than during the normal state. Diminution of salivation during hypnosis occurred in 26 of the 28 experimental sessions. (2) Subjects who liked lemon juice secreted more copiously than subjects who disliked it. (3) Results in the two control subjects are equivocal. Various hypotheses are suggested to account for the diminution of secretion in the hypnotized subjects and for the equivocal results in the control subjects.

TITLE Change of auditory threshold during reverie as related to hypnotizability. ABSTRACT "Morgan has stated that he has never been able to hypnotize a subject whose auditory threshold rose during reverie. Our data on eight hypnotizable subjects indicate that six of their auditory thresholds rose during reverie, which contradicts Morgan's hypothesis. We believe the rises in threshold were due to the acceptance of the suggestion to relax and daydream, which according to Morgan should lower the threshold."

AFFILIATION SOURCE Journal of General Psychology. 1937 17 167-170 TITLE A study of direct suggestibility and social introversion as related to auditory threshold and to reaction-time during reverie. ABSTRACT The auditory threshold and reaction-time during crystal-gazing as compared with normal threshold and reaction-time values, and the mean rate of arm movement in response to verbal suggestions and scores on the Nebraska Personality Inventory, were determined for each of 20 subjects. The amounts and direction of change in auditory threshold and in reaction-time during reveries seemed too unreliable to serve as measures of personality traits; they bore little relationship to social introversion or to direct suggestibility. The reliability of the test of direct suggestibility (arm movement in response to verbal suggestion) was comparatively high. Psycho-physical variability of auditory threshold seemed not to be related to introversion (Nebraska Inventory) or to direct suggestibility (arm movement).

TITLE Respiration and heart action in sleep and hypnosis. ABSTRACT Electrocardiograms and pneumograms were obtained from 8 subjects during hypnosis and sleep. During the hypnotic trance the experimenter always made certain that the subject was not asleep while records were being taken. "In general, so far as heart action and respiration are concerned, hypnosis resembles the waking state rather than sleep." These results differ from those of previous investigators, whose subjects may actually have been asleep instead of in a hypnotic trance. The apparatus and results are described in detail.

TITLE Electrocardiograms during sleep and hypnosis. ABSTRACT Analysis of electrocardiograms from 8 subjects during periods of hypnosis, of sleep, and of waking rest before and after each period of hypnosis as controls, showed, so far as cardiac action is concerned, that hypnosis resembled waking rest more than it resembled sleep. Heart-rate and 3 intervals of the heart-cycle as given in the electcroardiograms were considered, namely, the interval from the beginning of the P-wave to the beginning of the Q-wave, (P-Q interval), the interval from the beginning of the Q-wave to the end of the T-wave (Q-T interval), and the interval from the end of the T-wave to the beginning of the next P-wave (T-P interval). Heart-rate tended to be lowered by sleep, but not by hypnosis. Average times of P-Q were decreased and of Q-T increased during sleep, but not during hypnosis. The P-Q interval tended to vary inversely with cardiac rate during waking rest and during hypnosis, but not during sleep. These writers suggest that previous reports of cardiac action in hypnosis similar to that in sleep are based upon observations of sleep which was mistaken for hypnosis.

TITLE Facilitation of response to suggestion by response to previous suggestion of a different type. ABSTRACT Eight subjects were selected because they were hypnotizable. Postural changes in response to suggestion, received during the waking state, were compared with the same type of movement in the trance state. Suggestions regarding sleep were given by means of the Estabrook hypnotic-technique phonographic record. The suggestions regarding movement were standardized for this experiment by the preparation of an appropriate record. The feasibility of using phonograph records for the purpose of standardization of procedure is pointed out. Response to suggestions regarding the forward movement of the arm took place more rapidly in the trance than in the waking state. Eye closure incident to going into the trance took place more rapidly after response to suggestions regarding arm movement than it did when such response preceded the suggestions for sleep. There was evidence of a cumulative effect in successive suggestions regarding arm movement. Habituation is evident in the responses on following days in regard to both eye closure and arm movement. Practice curves show negative acceleration. There is a positive relationship between the length of time necessary for eye closure and that necessary for eye closure and that necessary for arm movement.

TITLE The role of discussion in changing opinion regarding a matter of fact. ABSTRACT When a considerable number of persons entered into discussion of a question of fact, either in a large group, or in several smaller groups, and learned that other individuals differed materially in their opinions regarding the question: (1) the number of individuals who did not alter their opinions was negligible; (2) the accuracy of the average judgment of the individuals was not improved; (3) the number of individuals who increased the accuracy of their estimates was approximately three times the number who did not improve their estimates; (4) the decrease in average of the individual errors was greater than when no opportunity was allowed for discussion; (5) the "typicality" of opinion was increased; (6) with the subjects divided into small groups, the range of opinion in every group was reduced; (7) the average amount of individual change was greater than when no opportunity was allowed for discussion. The average change of opinion was greater among women than among men. The most significant general conclusion is that discussion is not effective in changing opinion unless the individuals who enter into discussion become aware of differences in opinion held by others.

TITLE Social influences in the change of opinion. ABSTRACT The members of a group express as individuals views on some topic. Later the group is informed of the majority viewpoint, following which each individual again expresses his views. This article is the first of a series on the extent to which the individual alters his opinion to agree with the majority view. The topics considered were felt to be of sufficient interest to hold the attention of the subjects and possible of considerable diversity of opinion.

TITLE The recognition of facial expressions of emotion. ABSTRACT A review of the historical and contemporary literature, under the heads: analyses and portrayals of facial expression, the question of innate patterns, facial patterns in infants, the question of innate ability to recognize expressions, effects of training in recognition, effects of suggesting names, range of ability to recognize, sex differences in recognizing, relationship of ability to judge expressions to general intelligence and to social intelligence, identifiability of different patterns, problem of most important features, methods of identification. In general, it appears that little real progress has been made in reaching a definite solution of any major problem in this field.

TITLE Students' attitudes. ABSTRACT AUTHOR Katz, D.; Allport, F.H.; Jenness, M.B. AFFILIATION SOURCE Oxford, England: Craftsman Press (1931) Pp. xxviii, 408 pp.

TITLE Students' attitudes; a report of the Syracuse University reaction study. ABSTRACT This is a comprehensive study of student attitudes based on the Reaction Study at Syracuse University in 1926. The authors indicate factors bearing on the local situation in light of the intervening time and also contributions to the broader interests. The problems involved in questionnaire procedure and attitude studies are clearly discussed and the facts interpreted in the light of the same. The following factors are studied in detail: reasons for coming to college; selecting a certain college and remaining in same; college activities; curricular work; personal ideals of students; need for personal advice; choosing a vocation; fraternities; snobbishness; cribbing; co-education and moral standards of the sexes; religious beliefs; religious observances and attitudes towards churches; and changes in religious beliefs and practices during college life. The religious factors investigated are based upon the College of Liberal Arts group only. Fraternity and non-fraternity student attitudes are compared. The details of the study correlated very closely with findings of former specific studies both locally and generally. Fraternity men are divided into "institutionalist" (majority) and "individualist" (minority) types, with their respective attitudes as expressed by these terms. The changes in religious attitudes show a gradual change as over against the usual idea, or the more commonly expressed idea, of a sweeping collapse in beliefs and practices. A part of the general summary gives suggestions relating to psychology, sociology and political science in the way of recommending the procedures used for further investigation. The appendix includes a statement of the techniques of attitude measurement and a summary of college attitude studies with bibliography.

it would help if you actually explained the theory of beans in a jar because there is no full explaination of this experiment. therefore this web page had no controbution with my scientific study
