Fixation accuracy and perceptual asymmetry for consonants

Fixation accuracy was related to perception of laterally presented consonants. Small left-eye fixation inaccuracy influenced perceptual performance of 8 men and 8 women.     

Relating other's behaviour to own behaviour: Effects of delayed response and task difficulty

120 Ss from age groups 8, 12 and 16 years were tested for their understanding that another person's (O) sadness response was related to a preceding behaviour in S. The understanding was tested after experimental interaction episodes where E's assistant (O) worked on an (easy or difficult) task, was helped by S, and responded (immediately or delayed) with sadness. The results showed that a relating of O's behaviour to S was shown primarily for Ss in the two oldest age groups, and primarily when O's response was immediate. A delay of 11/2 min in O's response resulted in attributions of O's behaviour to psychological processes in O rather than to S's behaviour. The youngest Ss focused on O in explaining O's behaviour. Task difficulty did not effect Ss causal attributions.     

A simple and sensitive method for monitoring running-wheel movement

A running-wheel movement-detection method is described for use with a modified 1350 Commodore mouse and a Commodore 64, is described. The movement-detection method allows for the detection of partial revolutions and direction of movement, but requires no interface equipment. The modified running wheel is discussed as a new technique that may be useful for bridging empirical and theoretical differences between free-operant and discrete-trial runway procedures.     

Angular homeostasis: IV. Polygonal orbits

Some properties are discussed of regular polygons that may result from angular homeostatic processes in stable orbit. To characterize these homeostatic polygons we need to discuss the winding number, the sidedness (integer, fractional and irrational), multiplicity, envelopes, and density. A regular (i.e., equilateral, equiangular) polygon may be closed in one revolution about its unique center, in multiple revolutions, or not at all. A homeostatic polygon can be generated only if all vertices are included in a single polygon, which occurs if and only if the number of vertices and the number of revolutions required to complete the polygon are relatively prime. For the homeostatic polygon to have a finite number of sides (without repeating itself) the angle subtended by any two successive vertices at the center must be a rational multiple of 2. Biological implications of these properties are illustrated.     

Interhemispheric integration of compound nouns: effects of stimulus arrangement and mode of presentation

Normal subjects had to name German compound nouns which were presented tachistoscopically. The compound nouns were displayed either unilaterally to the left or right visual field or bilaterally with one element to each visual field. In the bilateral condition a distinction was made as to whether familiar or unfamiliar arrangement of the elements was used. Representation in print was compared with pictorial representation of the compound nouns. A right visual-field superiority was observed with printed representation, but no laterality effects with pictorial representation. Bilateral processing was superior to unilateral processing. Within the bilateral conditions, the familiar arrangement of the elements yielded a significantly better performance than unfamiliar arrangement. This difference can be explained by reading habits and/or by different styles of interhemispheric integration.     

Quantifying aggression: Effects of identity of stimulus

A test for children's insight into relations between behaviour and aggressive emotion showed that kindergarten children showed an increase in ratings of emotion corresponding to an increase in aggressive behaviour (positive relation), and that an increase in ratings of emotions corresponding to a decrease in aggression-related behaviour (negative relation) was shown by seven- and nine-year-old children. Cognition of relations between aggressive emotion and behaviour seemed to be developed earlier than cognition of relations between intention and behaviour as observed in a previous study. Results from the test also indicated that the magnitude of emotion ratings differed in identity (same stimulus person) and non-identity (differed stimulus persons) stimulus conditions.     

Teachers do not Deal in Widgets

Although the use of merit pay, incentive pay, bonus pay, and job promotion are well-established measures in the private or corporate sector of American society, few examples of successful teacher merit pay systems exist. In 1983, the Eastern Washington University Department of Education surveyed six major private corporations to determine whether corporate merit pay programs could be applied to teachers and educational institutions. Survey findings suggest several reasons why merit pay programs for teachers will probably fail: (a) lack of monetary goals; (b) the necessity for subjective evaluation, which requires multiple measurement devices, extensive supervision, and time; (c) the absence of a many-tiered corporate structure in most educational institutions; and (d) increased supervisory direction that could stifle creativity and flexibility.
