Studies on field establishment of monogerm sugar beet

SummaryThe percentage emergence from monogerm sugar-beet seed in field experiments was reduced by high soil moisture content and soil compaction, but was unaffected by soil temperature. Seed lots were differentially influenced when the soil conditions were very adverse. Pelleted seed emerged a little better in good soil conditions and was not more sensitive to high soil moisture content than raw seed.The relation between laboratory germination and the number of emerged seedlings was variable and followed no obvious trends, and there was no consistent rank order in the emergence ability of four commercial cultivars.

Sense mode and coupling in a vigilance task

Usarmymedical Research Laboratory, Fort Knox, Kentucky This investigation examined the performance of 36 Ss on three 90-min vigilance tasks. As time on task increased, there was a significant decrease in number of detections and false responses and a corresponding significant increase in response latency. The consistent rank order relationship between stimulus conditions suggests that there were uniform trends among these conventional response measures. There was a significant decline in sensitivity (d′) lor the closely coupled tasks, regardless of the sense mode involved. However, d′ remained fairly stable for the loosely coupled visual task. The significant increase in criterion values(β) suggest that Ss adopt a more conservative mode of responding with increasing time on task. Further, these data indicate that a lack of control of coupling effects, rather than sense mode specificity, may have confounded the interpretation of prior research on visualand auditory tasks.

Creativity and Allocentric Perception

Seven tests were used to measure allocentric-autocentric perception. The Remote Associates Test was used for selection of high, moderate and low creative female Ss. Intelligence was controlled and differences on WAIS subtest scores were examined. A consistent rank order was obtained among groups and Ss for the hypothesized construct. WAIS subtest differences could not be meaningfully related to creativity. Childhood experience data tended to conform to MacKinnon's suggestions.

Marital Adjustment and Prediction in Sweden

Marital-adjustment and marital-prediction test scores were determined for four groups in Sweden-happily married, general population, unhappily married, and separated couples. Mean scores for both marital adjustment and marital prediction formed a consistent rank order, with happily married at one end and separated at the other end of the continuum for both men and women. The differences between the means of the four groups were statistically significant in all instances. Correlations between marital-adjustment and marital-prediction test scores were also statistically significant for both men and women.
