Another View of Translation Manuals and the Study of Science

The article argues for the possibility of translation manuals having an implicit internal structure. This structure is composed of specific methodological assumptions and techniques. Using the (N)-type and (G)-type distinction developed by Fuller for the study of scientific behavior, it is shown that these are incomplete characterizations of translation manuals. A more complete characterization must involve an analysis of how the presence or absence of methodological rules influences the interpretation of specific research questions. It is further argued that while Quine's original indeterminacy thesis cannot be completely rejected, in some cases it can be modified to reflect the importance of the methodological constraints. Finally, it is suggested that the more critical analysis of translation manuals will benefit the on-going debates in the study of scientific behavior.     

Fluency,disfluency, dysfluency,and stuttering

The appropriate use of words, particularly certain words, is a persisting problem in the field of stuttering. This paper discusses some of the misuse involving four words basic to the field.     

Programming experiments on a TERAK 8510/A microcomputer

In the course of bringing up one’s first experimental microcomputer system, certain standard problems occur that are trivial to the experienced programmer but are great blocks to the novice. In this spirit, some paradigms that were implemented on a TERAK 8510/a microcomputer, and the related problems, are described. Specific topics include some consideration of timing procedures for reaction time experiments and how to handle large text files on small floppy disk systems.     

Biochemical correlates of personality traits in normals: An exploratory study

This study attempted to identify biochemical systems associated with the personality dimensions of Extraversion (E), Neuroticism (N), Psychoticism (P), Sensation Seeking (SS) and Impulsivity (Imp). The subjects were 43 normal volunteers who volunteered to take a battery of psychological tests and allow investigators to obtain samples of blood, urine and cerebrospinal fluid (CSF) for biochemical assessment.Substantial positive correlations were found between CSF norepinephrine (NE), MHPG (the principal metabolite of NE), DBH (an enzyme involved in the production of NE) and plasma MHPG and DBH; all of these are regarded, in some part, as putative indicators of central noradrenergic activity. After partialling out the influences of age, height and weight, a number of significant relationships were found between psychological traits and biochemical variables. Extraversion correlated positively and introversion and neuroticism correlated negatively with CSF Ca. Neuroticism also correlated negatively with plasma MHPG. Ego Strength (inversely related to Neurotic Introversion), P and Disinhibitory SS correlated negatively with CSF cort. General SS correlated negatively with CSF NE and plasma DBH, and these correlations were significant in both males and females, as well as in the total group. The results are consistent with some biological models of personality, but suggest the need for modification in others.

Timing the Selection of Information During Rhythmic Catching

Catching a ball requires that information be available close to the catch but early enough for prospective or corrective control. In the present experiment, 6 participants were asked to throw and catch a ball continuously for 1 min while wearing liquid-crystal goggles that restricted viewing to specific amounts of time at specific intervals. Participants were free to select the information by varying the frequency and phasing of throwing relative to the goggles. Video analysis revealed that they elected a frequency of throwing that matched the goggle frequency and chose to view the ball at or around its zenith. Earlier portions of the ball's trajectory were viewed as the goggle frequency increased. Despite variations in the viewing location, participants elected to view the ball on average 365 ms before the catch. Analysis of the hand's trajectory further revealed that the time interval (M = 82 ms) between the ball's zenith and the initiation of the final motion of the hand toward the catch did not vary as a function of the frequency of throwing. The authors conclude that the timing constraints imposed by the hand's movement are the basis for the selection of information for catching.     

Observations on the adaptation of induced motion

Induced motion (IM) was measured before and after a 10-min adaptation period during which subjects viewed the IM display without judging IM magnitude. The inducing stimulus was a rectangle, which contains both horizontal and vertical reference detail. The magnitude of IM was significantly lower following the adaptation period. This result is inconsistent with the hypothesis that adaptation of IM represents an instance of perceptual learning wherein the contribution of relative motion to motion perception is reduced. In a separate study, similar results were obtained when the inducing stimulus was a single vertical bar presented either to the left or to the right of the fixation stimulus. In addition, adaptation was obtained when the location of the inducing bar was changed during test measures, demonstrating that this effect is not specific to the retinal locus of the adaptation stimulus.     

Rational choice and polynomial measurement models

Rational choice behavior is defined in a manner that subsumes rational choice theory as part of general measurement theory. The special class of polynomial measurement problems are defined, and their solutions are reduced to solving polynomial inequalities. An algebraic criterion is given for the solvability of arbitrary finite sets of polynomial inequalities, resolving a conjecture of Tversky.
