Abstract: Do we perceive fine details in the visual periphery? Here, we propose that phenomenology in the visual periphery can be characterized by an inflated sense of perceptual capacity, as observers overestimate the quality of their perceptual inputs. Distinct from the well-known perceptual phenomenon of "filling-in" where perceptual content is generated or completed endogenously, inflation can be characterized by incorrect introspection at the subjective level. The perceptual content itself may be absent or weak (i.e., not necessarily filled-in), and yet such content is mistakenly regarded by the system as rich. Behaviorally, this can be reflected by metacognitive deficits in the degree to which confidence judgments track task accuracy, and decisional biases for observers to think particular items are present, even when they are not. In two experiments using paradigms which exploit unique attributes of peripheral vision (crowding and summary statistics), we provide evidence that both types of deficits are present in peripheral vision, as observers' reports are marked by overconfidence in discrimination judgments and high numbers of false alarms in detection judgments. We discuss potential mechanisms which may be the cause of inflation and propose future experiments to further explore this unique sensory phenomenon.

Marital duration has a negative effect on married men’s physical pleasure of marital sex, & it has no effect on married women’s sexual satisfaction

Liu, C. (2018). A theory of sex difference in changes in marital sexual satisfaction. Evolutionary Behavioral Sciences, http://dx.doi.org/10.1037/ebs0000120

Abstract: This paper develops and empirically tests a theory of one of the most fundamental sex differences, namely, the sex difference in the changes in marital sexual satisfaction. Previous research reports mixed results on how sexual satisfaction changes over relationship duration. More theoretical and empirical research is needed to better understand how each sex’s sexual satisfaction changes over relationship duration. In this research, applying an evolutionary psychological perspective and human capital theory, I attempt to explain and predict how each sex’s marital sexual satisfaction changes over marital duration. Three testable hypotheses are derived and empirically tested with the National Health and Social Life Survey data. The results show that marital duration has a negative effect on married men’s physical pleasure of marital sex, and it has no effect on married women’s sexual satisfaction. Implications for other aspects of marital sex and for marriage as a social institution for channeling sex are drawn. The limitations of the research are discussed.

Unmarried men’s increased financial satisfaction was associated with decreased relationship satisfaction, and increased financial stress was associated with decreased relationship satisfaction for unmarried men and married women (actor effects)

Totenhagen, C. J., Wilmarth, M. J., Serido, J., & Betancourt, A. E. (2018). Do day-to-day finances play a role in relationship satisfaction? A dyadic investigation. Journal of Family Psychology, 32(4), 528-537. http://dx.doi.org/10.1037/fam0000406

Abstract: Prior researchers have found consistent links between financial issues and relationship outcomes. Yet, because most research is cross-sectional or examines these constructs over longer periods of time (e.g., years), the microlevel processes of how and when these changes occur are unclear. In the present study, we use interdependence theory as a guide to examine the daily fluctuations of financial satisfaction and stress as well as their daily associations with relationship quality in married and unmarried heterosexual couples. Using a dyadic 14-day daily diary research design, we found both financial satisfaction and stress demonstrated significant within-person fluctuations, with women demonstrating greater volatility in financial satisfaction than men. Given that individuals varied in their perceptions of financial satisfaction and stress from day to day, we then examined how these fluctuations were associated with daily relationship satisfaction. We expected financial satisfaction would be positively associated with relationship satisfaction for both actors and partners, whereas financial stress would be negatively associated for both actors and partners. Hypotheses were partially supported. Unmarried women’s daily financial satisfaction was associated with increased relationship quality for both themselves (marginal) as well as their partners. An unexpected pattern for unmarried men’s financial satisfaction was found; their increased financial satisfaction was associated with decreased relationship satisfaction. Increased financial stress was associated with decreased relationship satisfaction for unmarried men and married women (actor effects). We discuss implications for research and practice.
