Analysis of the perception of motion concomitant with a lateral motion of the head

This study is concerned with two questions regarding the illusory motion of objects that occurs concomitantly with motion of the head. One is whether this illusory concomitant motion, unlike the perception of real motion, is paradoxical in the sense that, although the object appears to move, it does not appear to go anywhere. The second question is whether illusory concomitant motion can be explained by errors in convergence produced by a tendency for the convergence of the eyes to displace in the direction of the resting state of convergence. Both questions receive a negative answer. In Experiment 1, it is shown that the illusory motion perceptually can add to or subtract from apparent motion resulting from real motion. In Experiment 2, it is shown that, for a binocularly viewed object at a near distance, the error in convergence (fixation disparity) is far too small to be an explanation for the illusory object motion associated with a moving head. The results of both experiments support an interpretation of illusory concomitant motion in terms of errors in the apparent distance of the stimulus object and the veridical perception of its direction.     

Relative cues and absolute distance perception

It is possible, in theory, for the simultaneous occurrence of several different relative cues of distances to increase the veridicality of the perception of absolute distance. To test whether this actually occurs, a three-dimensional display was viewed monocularly while moving the head laterally, under conditions in which some error in perceived absolute distance was expected. The perceived absolute distance of the display was measured with the number of relative cues of distance within the display varied. No systematic reduction was found in the error in perceived absolute distance as a consequence of the variation in the number of relative cues. The study provides no evidence that the potential source of absolute distance information provided by relative cues is utilized by the visual system.     

Transference reactions in conjoint therapy: A view from an observation group

Summary This paper reports on conjoint therapy conducted with the individual therapists of two of the group's members observing the group sessions. The development of the transference reactions of all group members are highlighted and suggestions are made regarding the most useful methods of handling these transference reactions to help create a mutative experience for the members of the group.The author wishes to thank Dr. Judith Isaac for her comments and editorial assistance throughout the preparation of this paper.     

The Sander illusion as a function of relative space and component lines

Magnitude of the Sander illusion was measured as a function of two variables: (1) the orientation of the line normally separating the two smaller parallelograms and (2) the presence or absence of the horizontal lines and of the diagonal test lines. The results showed that, as the angle of the dividing line varied so as to shift the relative sizes of the two parts of the figure toward equality, the illusion effect decreased, approaching zero when the two areas were equal. The illusory effect was enhanced by the removal of the two test lines. Results were discussed in relation to the problem of assimilation vs contrast effects.     

The measurement of self-esteem for program evaluation

The purpose of this paper is to examine the area of self-esteem in the professional literature, its relationship to educational programs, its measurement problems, and one approach to program evaluation in terms of students' self-esteem. Self-esteem has been an important topic in the educational literature in recent years. There have been many important contributions by investigators on the relationship between self-esteem and educational achievement. Until recently, the results of self-esteem investigations have yielded a somewhat negative appraisal from reviewers, but there is optimism for the future possibilities of assessing this elusive construct. The investigator focusing upon program evaluation has advantages over his predecessors. He can utilize different measurement strategies. The strengths and criticisms of Q methodology are discussed. The L-L Q-Sort is presented as one approach to the evaluation of self-esteem in educational program evaluation.     

On a statistic arising in testing correlation

This paper is devoted to the study of a certain statistic,u, defined on samples from a bivariate population with variances ₁₁, ₂₂ and correlation . Let the parameter corresponding tou be . Under binormality assumptions the following is demonstrated. (i) If ₁₁ = ₂₂, then the distribution ofu can be obtained rapidly from theF distribution. Statistical inferences about = may be based onF. (ii) In the general case, allowing for _{11 22}, a certain quantity involvingu,r (sample correlation between the variables) and follows at distribution. Statistical inferences about may be based ont. (iii) In the general case a quantityt may be constructed which involves only the statisticu and only the parameter . If treated like at distributed magnitude,t admits conservative statistical inferences. (iv) TheF distributed quantity mentioned in (i) is equivalent to a certaint distributed quantity as follows from an appropriate transformation of the variable. (v) Three test statistics are given which can be utilized in making statistical inferences about = in the case ₁₁ = ₂₂. A comparison of expected lengths of confidence intervals for obtained from the three test statistics is made. (vi) The use of the formulas derived is illustrated by means of an application to coefficient alpha.This research was supported by the National Institute of Child Health and Human Development, under Research Grant 1 PO1 HD01762.     

From ‘Is’ to ‘Ought’ in Moral Epistemology

Many philosophers claim that no formally valid argument can have purely non-normative premises and a normative or moral conclusion that occurs essentially. Mark Nelson recently proposed a new counterexample to this Humean doctrine:All of Dahlia's beliefs are true.Dahlia believes that Bertie morally ought to marry Madeleine. Bertie morally ought to marry Madeleine.I argue that Nelson's universal premise has no normative content, that Nelson's argument is valid formally, and that Nelson's moral conclusion occurs essentially and not vacuously. Nonetheless, I show that Nelson's argument faces a more fundamental problem if it is used in moral epistemology. An argument that appeals to a moral authority, such as Dahlia, might justify some moral belief out of a contrast class that does not include extreme views like moral nihilism; but it begs the question against moral nihilism, since one cannot be adequately justified in believing the conjunction of its premises without depending on assumptions that moral nihilists would deny. Thus, arguments like Nelson's can accomplish something important in moral epistemology, but their use is strictly limited.     

Pastoral counseling for self-transcendence: The integration of psychology and theology

Conclusion In the concept of self-transcendence pastoral counseling can integrate psychology and theology by seeing them as two complementary interpretations of the single radical drive of the human spirit. By moving beyond ourselves in creative understanding, realistic judgment, responsible decision, and generous love we both realize our authentic being (true self) and respond to the gospel's call to loving service of the neighbor. A psychology that understands self-realization as self-transcendence and a theology that recognizes the gospel as a call to self-transcendence require no connecting bridge or reconciliation, only the discovery of their intrinsic unity as interpretations of the same fundamental human drive for self-transcendence.
