Apparent motion of stimuli presented stroboscopically during pursuit movement of the eye

This paper reports the first phase of a research program on visual perception of motion patterns characteristic of living organisms in locomotion. Such motion patterns in animals and men are termed here as biological motion. They are characterized by a far higher degree of complexity than the patterns of simple mechanical motions usually studied in our laboratories. In everyday perceptions, the visual information from biological motion and from the corresponding figurative contour patterns (the shape of the body) are intermingled. A method for studying information from the motion pattern per se without interference with the form aspect was devised. In short, the motion of the living body was represented by a few bright spots describing the motions of the main joints. It is found that 10–12 such elements in adequate motion combinations in proximal stimulus evoke a compelling impression of human walking, running, dancing, etc. The kinetic-geometric model for visual vector analysis originally developed in the study of perception of motion combinations of the mechanical type was applied to these biological motion patterns. The validity of this model in the present context was experimentally tested and the results turned out to be highly positive.     

Occupational prestige and appropriateness: The views of mental health specialists

Because of the extensive social and cultural changes associated with the women's equal rights movement, this study asked questions about how occupational prestige is related to differential views of women's roles with female and male psychotherapists, advanced graduate students, and secondary school counselors. The samples differ very little in their rankings of occupational prestige. However, differences did emerge between each sample's judgments of which occupations are appropriate for women, with school counselors being the most likely to rate occupations as inappropriate for women.     

Target position and practice in the identification of letters in varying contexts: A word superiority effect

A forced-choice detection paradigm controlling for postperceptual inference was used to investigate letter identification in three-position displays. Letters from a predesignated set of four targets appeared singly, in strings of noise characters, in unpronounceable nonsense strings, and in words. Subjects knew which context would occur, but did not know which of the three display positions would contain the target. Correct detection data were collected at constant exposure duration over five testing sessions. Overall identification accuracy was higher in words than in all other contexts, the first word superiority effect to be found with targets specified in advance since Reicher’s (1969). This effect remained constant over sessions. An interaction between context type and target position showed enhanced accuracy for initial and terminal letters in words, but depressed accuracy at initial and terminal positions in other contexts. This was interpreted to mean that prior knowledge of context is used to alter the dynamics of perceptual analysis.     

The social postulate of theoretical ethics

Conclusion Kant believed all and only the guilty should be punished. Other retributivists believed that only guilt should bring punishment down on a person. In neither way is the retributive theory sufficiently distinguished from utilitarianism for, on contingent grounds, the utilitarian may agree with either of these theses. The advantage of PRJ is that it brings out the difference between retributivism and utilitarianism more sharply while at the same time it manages to be a less stern and unyielding view than traditional retributivism. The retributivist need not deny the core of good sense in utilitarianism, and he certainly need not deny the connection between morality and happiness. His view is that punishment does not have to produce good consequences in order to be justified. It suffices that it be deserved and that it not produce a set of clearly bad consequences. If it is true that punishment generally does have bad consequences which more than outweigh its good consequences then retributivists and utilitarians should join hands in their condemnation of punishment. The heart of the difference between the retributivist and the utilitarian is that the latter counts punishment itself as an evil but believes that, generally speaking, it is an evil which is instrumental in the production of enough good to out-weigh its intrinsic demerit. The retributivist does not regard punishment as an evil. The pain of punishment is not by itself a reason for not punishing (so long as it is not excessive). Insofar as utilitarianism is the view that no considerations but those of utility should justify punishment, it is only one side of that counterfeit coin the other side of which is Kant's dictum: ...Woe to him who creeps through the serpent-windings of Utilitarianism to discover some advantage that may discharge him from the Justice of Punishment, or even from the due measure of it.... It is irrational for Kant to rule out concern for utility but it is also irrational for the utilitarian to rule out concern for retribution.I have tried to show in this paper that the two main aspects of a plausible theory of retribution - PRJ and that the punishment should fit the crime - can be vindicated in terms of acceptable beliefs one of which is incompatible with utilitarianism (PRJ), and one of which does not derive the respect we accord it from any connection with utilitarianism. I emphasize, however, what I previously stated, that the retributivist does not have to believe that retributive justice must prevail at all costs. What is asked for is the recognition that one purpose of punishment (and not the one purpose) can justifiably have nothing to do with utility. The sensible retributivist will concede, and gladly, that there are more things in heaven and earth than retribution.     

Do Self-Ideal Discrepancies and Global Self-Esteem Amount to the Same Thing?: An Empirical Investigation

Measures of self-esteem differ considerably in the assumptions they make about the nature of the construct. These differences are often overlooked in discussions of self-esteem. An examination was accordingly conducted of the relationship between measures of the distance between actual self and ideal self (derived from repertory grids) and an adapted version of Rosenberg's measure of global self-esteem. The stability over periods up to 15 months of both kinds of measure was also examined. Two samples (N = 20 and N = 28) of students and recent graduates provided data as part of a longitudinal study of career development. Results differed between samples, but in general indicated that global self-esteem overlaps with but is not the same as the discrepancy between actual self and ideal self. Scores were generally stable over time. Explanations for the results are discussed, together with their implications for how we should construe self-esteem.     

Asymmetry of the effective visual field in reading

In three experiments, subjects’ eye movements were recorded as they read from a computer-controlled CRT. The amount of information available to the left and right of the fixation point was varied in order to determine the characteristics of the effective visual field in reading. Experiments 1 and 2 demonstrated that readers do not obtain useful information during a fixation more than 3 or 4 letters to the left of their fixation point. The results of Experiment 3 indicated that the effective visual field does not extend any further to the left than the beginning of the word currently fixated, independent of the number of letters available to the left of fixation. When combined with the results of other research on the perceptual span in reading, the results of these experiments indicate that the effective visual field extends from the beginning of the currently fixated word (but no further than 4 characters to the left of fixation) up to about 15 characters to the right of fixation.
