A test-theoretic approach to observed-score equating

Observed-score equating using the marginal distributions of two tests is not necessarily the universally best approach it has been claimed to be. On the other hand, equating using the conditional distributions given the ability level of the examinee is theoretically ideal. Possible ways of dealing with the requirement of known ability are discussed, including such methods as conditional observed-score equating at point estimates or posterior expected conditional equating. The methods are generalized to the problem of observed-score equating with a multivariate ability structure underlying the scores.

A recruitment theory of simple behavior

A statistical theory of choice is developed using a sequential sampling assumption. Response latency distributions for certain simple reaction-time situations are derived and tested. Both response probability and response latency measures are developed for a two-alternative judgment situation and the relationship between the two measures explored. The sampling parameter is proposed as a means of representing incentive conditions in choice situations and ROC curves are obtained by appropriate manipulations of this parameter. A solution to the overlap problem in simple discrimination-learning situations is also derived.This research was supported in part by a grant from the National Science Foundation. The writer has benefited from discussions with his students, James R. Erickson, James G. Greeno, Duane R. Martin, Kirk H. Smith, and Charles F. Stroebel. For generous suggestions with regard to certain mathematical matters, the writer is indebted to Professors Ingram Olkin, Stephen Orey, and Milton Sobel of the Statistics Department at the University of Minnesota.     

The oedipal wound in two stories by Kafka: The Metamorphosis and A Country Doctor

Kafka read Freud and was interested in psychoanalysis but believed there was no ‘cure’ for what was essentially the problem of living. As always with creative artists, the writer is his own psychoanalyst, and the actual process of writing is his means of self-revelation. The aim of this paper is to consider, in relation to two stories (The Metamorphosis and A Country Doctor), Kafka’s use of this background oedipal conflict with his father or received values (the ‘law’) as a springboard for the type of wound that results in creative writing. The wound for him became a kind of personal myth, and was also associated with other painful stimuli, including his tuberculosis and his troubled love affairs, but above all with his identity as a writer. The writing process and the ‘faith-value’ it demands is an underlying metaphor behind these narratives of Kafka’s ‘dream-like inner life’. There are parallels here with Bion’s psychoanalytic philosophy of ‘suffering’ and ‘psyche-lodgement’.     

Tradition and Infantile Fantasy in the Shape of Modern Antisemitism

The narrative form is chosen to tell the story of a six-year analysis of a man in his thirties (K), who was given various diagnoses, including schizophrenia, during his many stays in psychiatric hospitals. K grew up in deprivation with a psychotic mother. The writer tries to capture the essence in a psychoanalytic process that takes its starting point in the loss of transparence in the basic psychic tissue and describes this tissue's partial renewal. In addition, the writer would like to convey a basic element in an individual's struggle to become a person. Or how the soul may be saved.     

Complex decision-making in early childhood

Decision-making over time is an important aspect of adaptive social functioning. The main goal of this study was to investigate the development of this ability in young children. A simplified version of the Iowa Gambling Task was given to 69 children at 3 ages (3, 4, and 6 years). Children were also given an awareness test to assess their knowledge of the task. Significant age differences were found for awareness of the task while significant sex effects were found for performance on the task. Females chose significantly more from the advantageous decks than would be expected by chance in the second block. Males demonstrated no significant difference in choice of decks. Further analysis indicated female superiority in the task was not due to greater knowledge of the game. One interpretation of these results is that there are two systems affecting decision-making over time.     

Thurstone's analytical method for simple structure and a mass modification thereof

The analytical method for simple structure proposed by Thurstone is applied to four separate cases and found to yield satisfactory results. The simple structure obtained by Thurstone's method is found to match closely that obtained by other methods and corresponds to the true structure of the matrix in those cases where true structure is known. Difficulties about the choice of the correct trial vector led the writer to develop a modification of Thurstone's method, useful where high speed computational facilities are available. Instructions are given for this so-called mass modification, and the procedure is illustrated with a 5-factor, 14-variable example. While the results do not fully correspond to a previous graphical solution, it can be argued that the results obtained by the new method show an improved simple structure. The modified method is applied to three other correlation matrices, yielding in each case a satisfactory simple structure.Contribution No. 961 from the Department of Entomology, University of Kansas, Lawrence, Kansas.Most of the work on which this paper is based was performed during the summer of 1956 when the author was the holder of an Elizabeth Watkins Faculty Scholarship granted by the Kansas University Endowment Association.

The true distributions of the range of rank totals in the two-way classification

This paper presents the results from an investigation of the true probability distributions of the range of rank totals. A procedure for generating an approximation to the true distributions is also given. A comparison of the results of this approximation with an extensive criterion of generated true and sample distributions, and with other approximations is indicated. Accurate estimates of the critical ranges necessary to reach significance at three commonly used alpha levels, where the number of judges and items is less than or equal to sixteen, are presented in tabular form.     

Catching ghosts

There are few psychoanalytically informed, first-person commentaries on the creative process of writing fiction. In this paper, the author, a psychoanalyst with a parallel career as a children's book writer, explores his associations, autobiographical details, and related theoretical constructs as they relate to the writing of one of his published picture book texts. Lastly, he questions whether a piece of fiction not only illustrates the writer's current and past history, but also points to the writer's future psychological potentialities.     

FRANZ KAFKA'S MUSICAL DIET

The anxiety that Franz Kafka felt about his identity as a man, a Jew, a member of the writer’s guild, a citizen of the twentieth century, is clear. How two major focuses of his anxiety – his inability to appreciate musical high culture and his vegetarian eating practices – were linked in his world is the topic of the present paper.

Maximizing predictive efficiency for a fixed total testing time

For any fixed total time of testing it is possible, through proper item-and-time allotment, to combine tests into a battery so that the multiple correlation with a pre-assigned criterion will be maximized. By holding constant the ratio of the length in number of items to the time length for each test, a set of general equations has been derived which will yield this maximum value of the multipleR and will enable one to determine, in any given case, the optimal fraction of total testing time that should be devoted to each type of test under consideration. The set of general equations is applied to a two-test-battery problem to obtain the optimal length of each type of test for one hour total testing time. If two other tests had been selected for the two-test sample problem, different subdivisions of the total time would generally occur. The manner in which the results would change when using other tests with different initial reliability, validity, and intercorrelation values is briefly presented. Some general implications of this method of battery development are also discussed.The writer is indebted to Max Woodbury for his assistance and especially to Dr. N. J. F. Van Steenberg and Dr. Anna S. Henriques, who provided valuable guidance and aid in the development of the solution to this problem.

THE RELIGION OF A SCIENTIST: EXPLORATIONS INTO REALITY (RELIGIO PHILOSOPHI NATURALIS)

Abstract. Sir Thomas Browne's reflection on the synthesis between his Christian religion and his practice as a medical doctor, made over three centuries ago, leads into reflections on the present relation between religion and science in the personal experience of the writer. An account is given of how the actual practice of scientific investigation led the author to theistic inferences and how the study of DNA provoked questions concerning reductionism and emergence. This evoked the need for a map of knowledge, and an attempt is presented in a figure which also serves to clarify what kind of realistic reference is involved in both scientific and humanistic contexts–especially with respect to personal language. Theological investigations thereby receive at least provisional legitimization and, with this encouragement, the article pursues the questions of the nature of the divine Source ("God") of the world's being and becoming, of God's interaction and communication with the world, especially with human beings in that world. The penultimate section outlines why the writer considers an explicit communication from God to humanity in Jesus of Nazareth is coherent with the foregoing and what this implies for human fulfillment, individually and corporately. The article concludes with a plea for humility before God and nature in our inquiries in the spirit both of Sir Thomas Browne and of the arch "agnostic" T. H. Huxley.     

Missing the dog that failed to bark in the nighttime: on the overestimation of occurrences over non-occurrences in hypothesis testing

In three studies, we investigated whether and to what extent the evaluation of two mutually exclusive hypotheses is affected by a feature-positive effect, wherein present clues are weighted more than absent clues. Participants (N = 126) were presented with abstract problems concerning the most likely provenance of a card that was drawn from one of two decks. We factored the correct response (the hypothesis favored by the consideration of all clues) and the ratio of present-to-absent features in each set of observations. Furthermore, across the studies, we manipulated the presentation format of the features’ probabilities by providing the probability distributions of occurrences (Study 1), non-occurrences (Study 3) or both (Study 2). In all studies, both participant preference and accuracy were mostly determined by an over-reliance on present features. Moreover, across participants, both confidence in the responses and the informativeness of the present clues correlated positively with the number of responses given in line with an exclusive consideration of present features. These results were mostly independent of both the rarity of the absent clues and the presentation format. We concluded that the feature-positive effect influences hypothesis evaluation, and we discussed the implications for confirmation bias.     

Altering the Shape of Punishment Distributions Affects Decision Making in a Modified Iowa Gambling Task

Neuroeconomics research has shown that preference for gambling is altered by the statistical moments (mean, variance, and skew) of reward and punishment distributions. Although it has been shown that altered means can affect feedback‐based decision making tasks, little is known if the variance and skew will have an effect on these tasks. To investigate, we systematically controlled the variance (high, medium, and low) and skew (negative, zero, and positive) of the punishment distributions in a modified version of the Iowa Gambling Task. The Iowa Gambling Task has been used extensively in both academic and clinical domains to understand decision making and diagnose decision making impairments. Our results show that decision making can be altered by an interaction of variance and skew. We found a significant decrease over trials in choices from the decks with high variance and asymmetrically skewed punishments and from the decks with low variance and zero skew punishments. These results indicate that punishment distribution shape alone can change human perception of what is optimal (i.e., mean expected outcome) and may help explain what guides our day‐to‐day decisions.

Differences in factor content of rights and wrongs scores

The right-response scores and wrong-response scores of speeded aptitude tests were factor analyzed to determine whether they differ in factorial content. The information thus obtained was used to derive scoring formulas that yield purer measures of a factor than do scoring formulas derived in other ways.This paper is a revision of a dissertation submitted in partial fulfillment of the requirements for the Doctor of Philosophy degree at the University of Southern California, 1948, and a paper read to the American Psychological Association in September, 1949.

Guilford for providing the intercorrelation and distribution data from the files of the School of Aviation Medicine and for general guidance throughout the study.

Der Stellvertreter

Based on the analytic work on colleagues the author investigates a writer’s block of German psychoanalysts when writing about their patients. In the process of their own therapeutic analysis, an inhibition of association in these psychoanalysts comes to the fore by them falling into the professional role and talking about their patients. The accounts of these colleagues on their own patients function as a doubled imago revealing the unconscious conflicts of the patients as well as acting as a proxy of the psychoanalysts’ impulses, affects and foreclosed memories in their own analysis. The inhibition of thinking, leading to a writer’s block, is the result of the correspondence of the trauma of the patient with the trauma of the analyst when the transference-countertransference relationship evokes annihilation anxieties in the psychoanalyst. Therefore the writer’s block of these psychoanalysts is rooted in their professional work and is the result of the internalization of precarious emotional contents of their patients. The author examines the role of institutionalized psychoanalysis in developing a professional writer’s block, and the results of the paper highlight the need of an emotionally supporting professional environment for the psychoanalyst during his training and his practice work.     

Working memory involvement in emotion-based processes underlying choosing advantageously

The Iowa Gambling Task (IGT) is widely used to assess decision making under conditions of uncertainty in clinical as well as in nonclinical populations. However, there is still debate as to whether normal performance at this task relies on implicit, emotion-based processes that are independent of working memory. To clarify the role of working memory on normal performance on the IGT, participants performed the task under low or high working memory load. We used a modified version of the original task, in which the position of the four decks was randomized between trials. Results showed that only participants performing under low memory load significantly chose more advantageously halfway through the task. In addition, when comparing the number of cards chosen from the two decks with frequent losses, one advantageous and one disadvantageous, only participants performing under low memory load chose more cards from the advantageous deck. The present findings indicate that the processes underlying optimal advantageous performance on the IGT rely on working memory functions.     

Individual distributions under ordinal measurement

For ordinal measurement the concept of an individual propensity distribution is developed. For any given individual the mean of this distribution is his true score, for which estimation procedures are discussed. Two measures of individual dispersion are considered and their distributions derived in the null case. These measures are shown to be counterparts at the individual level of Kendall's tau and Spearman's rho. Estimation of the two dispersion measures from sample data is investigated, and the relation of these estimates to the variance of the individual propensity distribution is derived.     

The ordinary

This paper discusses Peter Lomas's work in the context of the concepts of ‘ordinary people’ and ‘ordinary language’. Obsessions about whether a person is ordinary or not tend to occur in people who are disturbed. Psychoanalysts use the special language of mechanics to explain the phenomena they observe in the consulting room. In this paper it is argued that ordinary language, our mother tongue, is a better way of understanding people. In his work as a psychotherapist and writer, Peter Lomas found more insight in the ordinary language of literature than he did in theory.     

ON THE ANALYST'S IDENTIFICATION WITH THE PATIENT: THE CASE OF J.‐B. PONTALIS AND G. PEREC

The writer Georges Perec was in psychoanalysis with Jean‐Bertrand Pontalis for four years in the early 1970s. In this essay, the author presents the exceptional interest this analyst took in this patient and the ways in which that interest manifested itself in his work, psychoanalytic and otherwise. Many correlative factors suggest that identificatory processes persisted beyond the treatment and were maintained into Pontalis's later life. While this paper is primarily intended to provide evidence to support this view of a specific case, the author closes by reflecting that this may be a more general phenomenon and the reasons for this.
