A multi-locus continuous-time selection model.

A continuous time selection model is formulated for a diploid monoecious population with multiple alleles at each of an arbitrary number of loci, incorporating differential fertility and mortality as well as arbitrary mating and age structure. The model is simplified in the case of age-independence and for the case of a stable age distribution. The age-independent model is examined in detail for the special case of multiple alleles at each of two loci. This model is analyzed under the assumptions of random mating and additive fertilities, with close attention given to the behavior of the system with respect to Hardy-Weinberg proportions and linkage equilibrium.

Lack of memory for nonattended items in dichotic listening.

Three experiments were conducted to investigate whether semantic information presented to the unattended ear in a dichotic listening experiment has a memory effect after 30 sec. In all three experiments the Brown-Peterson paradigm was employed. Experiment 1 used the release from proactive inhibition technique and found no evidence that semantic material presented to the unattended ear produced proactive inhibitory effects on attended ear material. Experiment 2 suggests that this result was not due to a memory deficiency resulting from a lack of intent to learn. Experiment 3 indicates that repetition of the same information for three trials to the unattended ear did not enhance memory performance when the material was later presented to the attended ear. Assuming that some semantic processing does occur at the time of input, an interpretation based upon the levels-of-processing approach was suggested as a possibility for explaining the negative results.
