Spatial and temporal contributions to the structure of spatial memory.

Three experiments investigated the effects of spatial and temporal contiguity in item recognition, location judgment, and distance estimation tasks. Ss learned the locations of object names in spatial arrays, which were divided into 2 regions. The names of locations were presented during map learning so that critical pairs appeared close in space and close in time, close in space but far in time, far in space but close in time, and far in space and far in time. Names primed each other in recognition only when they were neighbors in both space and time. In contrast, the effects of spatial and temporal contiguity in priming in location judgments were additive. Finally, temporal contiguity affected estimates of Euclidean distance when locations were close together, but not when they were far apart.

MMPI-168 factor structure: A replication with public mental health patients.

Separate analyses of 5-, 6-, and 7-factor solutions for the 1st 168 MMPI item responses from a large (2,116) unselected sample of public mental health patients revealed close correspondence with the 6 factors derived by J. E. Overall et al (1973). The 7-factor solution, however, did provide some help in clarifying the psychological significance and differentiation of the factors involved.

Determination of the shortest interatomic distance in a liquid metal using its structure factor

The structure factor (SF) and atomic radial distribution function (RDF) of liquid lead simulated at a temperature of 613 K are compared. The shortest interatomic distance obtained from SF is found to be smaller than that determined as the abscissa of the first RDF coordination peak. It is shown that a satisfactory agreement between the experimental and calculated curves in the high-angle portion of SF can only be obtained when at least two most probable shortest interatomic distances r ₁ and r ₂, which indicate a complex structure of the first coordination shell of the liquid metal, are taken into account.
