The present study took a critical look at a central construct in couples research: relationship satisfaction. Eight well-validated self-report measures of relationship satisfaction, including the Marital Adjustment Test (MAT; H. J. Locke & K. M. Wallace, 1959), the Dyadic Adjustment Scale (DAS; G. B. Spanier, 1976), and an additional 75 potential(More)
We have isolated a dominant mutation in a gene called Son of sevenless (Sos) that is an allele-specific suppressor of the sevenless phenotype. This suppressor function is autonomously required in R7 and is sensitive to the dosage of the Sos and bride of sevenless genes. Loss-of-function alleles of Sos are recessive lethals, but in the eye Sos has a role in(More)
Measures of communication and aggression, taken from 56 newlywed couples, were used to predict marital outcomes 4 years later. Aggression discriminated between separated or divorced couples and those who remained married. In contrast, communication discriminated between couples who were maritally satisfied after 4 years and those who were married but(More)
Two studies examined the role of mindfulness in romantic relationship satisfaction and in responses to relationship stress. Using a longitudinal design, Study 1 found that higher trait mindfulness predicted higher relationship satisfaction and greater capacities to respond constructively to relationship stress. Study 2 replicated and extended these(More)
Specific skills and affective expressions coded from the problem-solving interactions of 172 newlywed couples were examined in relation to 8-wave, 4-year trajectories of marital satisfaction. Effects varied as a function of whether husbands' versus wives' topics were under discussion and whether husbands' versus wives' satisfaction was predicted, but(More)
Measures of communication, hostility, and neuroticism taken from 85 couples from Germany before marriage were used to predict marital outcomes 5 years later. Hostility and neuroticism discriminated between couples who separated or divorced after 5 years and those who remained married, whereas communication discriminated between married-satisfied and(More)
Extending dual process frameworks of cognition to a novel domain, the present study examined how mothers' explicit and implicit attitudes about her child may operate in models of parenting. To assess implicit attitudes, two separate studies were conducted using the same child-focused Go/No-go Association Task (GNAT-Child). In Study 1, model analyses(More)
The Son of sevenless (Sos) protein functions as a guanine nucleotide transfer factor for Ras and interacts with the receptor tyrosine kinase Sevenless through the protein Drk, a homolog of mammalian Grb2. In vivo structure-function analysis revealed that the amino terminus of Sos was essential for its function in flies. A molecule lacking the amino terminus(More)
Mutations in a gene called sextra (sxt) have been isolated. Loss of one copy of sxt promotes R7 photoreceptor cell development in a genetically sensitized background, while loss of both copies results in precursors of non-neuronal cone cells transforming into R7 cells. The requirement for sxt function is cell-autonomous. The transformation of cone-cell(More)
Ellipsoid and toroid-shaped articulations for total wrist prostheses were evaluated using computer modeling and laboratory experiments. An ellipsoidal design was found to accommodate greater width of the concave proximal component, resulting in better capture and prosthetic stability than a toroid shape. An ellipsoid articulation also provides greater(More)
