This study examined relations between aspects of family functioning and positive and negative dimensions of forgiveness. Increased understanding of one's partner and decreased anger about betrayal characterize positive forgiveness, whereas experiences such as holding a grudge and desiring revenge indicate negative forgiveness. The sample included 87 wives and 74 husbands who reported experiencing a significant betrayal, their partners, and their adolescent children. Analyses of reported forgiveness revealed that more negative forgiveness was associated with lower marital satisfaction for husbands and wives; trust partially mediated this relationship for husbands and wives. Greater positive forgiveness reported by husbands and wives predicted their own reports of a stronger parenting alliance, whereas greater negative forgiveness reported by husbands and wives predicted their spouses' reports of a weaker parenting alliance. For wives, more negative forgiveness also predicted higher levels of children's perceived parental conflict, and parents' reported conflict mediated this association for wives. Findings suggest that forgiveness of a marital betrayal is significantly associated with marital satisfaction, the parenting alliance, and children's perceptions of parental marital functioning.

Although the zebrafish has become an important model in visual neuroscience, little has been done to examine the processing of its higher visual centers. The purpose of this work was twofold. The first purpose was to examine the physiology of the zebrafish retinotectal system and its relationship to retinal physiology. Spectral sensitivity functions were derived from visually evoked tectal responses and these functions were compared to the functions of electroretinogram (ERG) responses obtained using the same stimulus conditions. The second purpose was to examine the recovery of visual functioning of the tectum following optic nerve damage. The optic nerves of adult zebrafish were damaged (crushed), and tectal visual processing was assessed following damage. The results showed that the spectral sensitivity functions based on the On-responses of the tectum and ERG were qualitatively similar. The functions based on each response type received similar cone contributions including both nonopponent and opponent contributions. However, the spectral sensitivity functions based on the Off-responses of the tectum and ERG differed. The results also showed that the zebrafish visual system is capable of neural regeneration. By 90 days following an optic nerve crush, the spectral sensitivity function based on the tectal On-response was similar to functions obtained from normal zebrafish. Although the tectal Off-response did recover, the spectral sensitivity based on the Off-response was not the same as the function of normal zebrafish. These results support the notion that different levels of the visual system process information differently and that the zebrafish visual system, like those of other lower vertebrates, is capable of functional regeneration.

This longitudinal study investigated the effects of expectations of effort of self and spouseon the marital quality of marital enrichment seminar participants. Self-report measures of marital quality, expectations regarding effort put into implementing what was learned during the seminar, amount of perceived effort, and satisfaction with effort were administered before and after the seminar, as well as at a 2-month follow-up. Participants (147 women, 95 men) attended community-based marital enrichment seminars in 12 U.S. cities. Multivariate path models indicated that larger discrepancies between expectations of effort postseminar and perceived effort at 2-month follow-up were associated with less satisfaction with perceived effort. Furthermore, participants' dissatisfaction in their spouses' effort had a negative effect on marital quality while controlling for initial marital quality, whereas dissatisfaction in their own effort did not. These findings highlight the possible detrimental
