Divorce,single parenthood and stepfamilies: Structural implications of these transactions

This article focuses on change in the family structure during the divorce as well as in the sequential stages of single parenthood and the reconstituted family. Special characteristics of these families and the tasks to be undertaken to enable the new unit to function are discussed conceptually and through case illustrations. Family therapy is seen as particularly helpful during the crisis stage when either a parent leaves or a new unit is added to an established one. The necessity of being aware of and working with all parts of the system, both the split-off and the newly-added, is stressed.     

Sex differences in verbal skills: Use of spelling-sound and lexical information

An experiment is described in which possible sex differences in lexical and phonological skills were investigated. A spelling test was used which could not be done on a phonological basis alone and which entailed lexical access for good performance. Women were judged on the evidence for this task to have better lexical ability than men, but no difference was found on a task designed to tap knowledge and use of phonological information in the form of spelling-sound correspondences.     

Spatial and movement-based heuristics for encoding pattern information through touch

Seven experiments investigated the heuristics people use to encode spatial pattern information through touch. Observers traced a tangible pathway with one hand and then answered questions about either the euclidean line between the pathway endpoints or the pathway itself. Parameters of the euclidean line were held constant, while characteristics of the felt pathway were manipulated. Experiments 1-4 showed that blindfolded sighted and blind observers increasingly overestimated the length of the euclidean line as the length of the explored pathway increased. This indicates a movement-based heuristic for encoding distance. Experiments 5-7 indicated that judgments of the position of the euclidean line did not vary with the position of the felt pathway or the extent to which it deviated from that line. Instead, the results indicated that observers relied on implicit spatial axes, which are movement independent, to judge position. These and other results have implications for theories of haptic encoding of spatial pattern and for the construction of tangible graphics displays.     

The Role of Reproductive Strategies in Academic Attainment

Since there is a tradeoff between prolongedformal education and early reproduction, education canbe construed as a long-term reproductive tactic. Thisreproductive strategies approach was tested by looking at relationships between sociosexuality (SOI)and parental investment (parental income, number ofsiblings, parental divorce, number of step siblings,birth intervals, birth order, closeness to parents) and GPA of 139 White students at a privatecollege. Parental investment was reduced to threefactors (Family Composition, Family Security, andMarital Instability), the last of which was negativelycorrelated with GPA and positively correlated with SOI.SOI was a much stronger (negative) predictor of GPA inwomen, but not men, than ACT was. Results support thereproductive strategies approach and imply that prediction of academic difficulty (and genderdifferences therein) must confront reproductiveissues.
