De Finettian Logics of Indicative Conditionals Part I: Trivalent Semantics and Validity

Journal of Philosophical Logic - This paper explores trivalent truth conditions for indicative conditionals, examining the “defective” truth table proposed by de Finetti (1936) and...     

Baselining affects the production of deceptive narratives

Recent research shows that the quality of a baseline (i.e., the analysis of one's behavior in normal conditions) decreases when the second narrative is expected and deceitful. However, a first step would be to investigate whether the writing of a first narrative might influence the second, independently of its expectancy. In this study, we hypothesized that second narratives would be less detailed, especially if these narratives are deceptive. Participants (N = 71) were asked to narrate two consecutive truthful and deceptive narratives. The second narrative was unexpected, and the order of the narratives was counterbalanced. Results suggest a detrimental effect of deceptiveness and order on the frequency of details. Moreover, an interaction was observed, suggesting when narratives are written after a first one, the frequency of details decreases, all the more if they were deceptive. The results of this experiment are discussed from both a theoretical and an applied perspective.     

Reproductive Decision-Making in MMR Mutation Carriers After Results Disclosure: Impact of Psychological Status in Childbearing Options

Reproductive techniques such as prenatal diagnosis (PND) or preimplantation genetic diagnosis (PGD), although debated, are legally forbidden in France in case of Lynch syndrome. The preference of mutation carriers about their reproductive options is not systematically considered in France. We aimed to prospectively assess the reproductive preferences of mismatch repair mutation carriers consulting in our institution (2003–2010, n?=?100). We also considered the short- and long-term post-disclosure psychological impact using the Impact of Events Scale-Revised questionnaire to measure the prevalence of posttraumatic stress disorder (PTSD) in those patients. Complete data were obtained for 34 respondents (17 males, 17 females, median age of 33.5 years [22–59]). Seventeen respondents (57 %) preferred spontaneous natural conception versus 28 % and 35 % choosing PND and PGD, respectively. At results disclosure, respondents mainly explained their distress by fear of premature death (43 %) and transmitting mutated genes (42 %). One year later, this last fear remained predominant in 55 % of subjects. None of the main socio-demographical, psychological or medical variables (including fear of transmitting mutations) was significantly associated with the reproductive preferences. Results disclosure had a real and time-decreasing psychological impact on mutation carriers. Reproductive techniques, expected to decrease the hereditary risk, were not significantly preferred to natural conception.

On the Assessment of Situational Intrinsic and Extrinsic Motivation: The Situational Motivation Scale (SIMS)

The purpose of the present research was to develop and validate a situational (or state) measure of motivation, the Situational Motivation Scale (SIMS). The SIMS is designed to assess the constructs of intrinsic motivation, identified regulation, external regulation, and amotivation (E. L. Deci & R. M. Ryan, 1985, 1991) in field and laboratory settings. Five studies were conducted to develop and validate the SIMS. Overall, results show that the SIMS is composed of 4 internally consistent factors. The construct validity of the scale is also supported by correlations with other constructs as postulated by current theories. Moreover, the SIMS is responsive to experimental induction as evidenced by data gathered through a laboratory study. In sum, the SIMS represents a brief and versatile self-report measure of situational intrinsic motivation, identified regulation, external regulation, and amotivation.     

Attachment,trust, and satisfaction in relationships: Investigating actor,partner, and mediating effects

Romantic relationship dissatisfaction has been cited as a primary reason for seeking mental health services (H. M. Foran, M. A. Whisman, & S. R. H. Beach, 2015). An increasing number of studies have revealed the importance of romantic attachment in understanding relationship satisfaction (M. Mikulincer & P. R. Shaver, 2016). This study aims to assess dyadic trust as a possible mediator of the relation between insecure romantic attachment and relationship satisfaction within a Canadian community sample of 199 heterosexual couples. Results revealed significant actor and partner effects. Specifically, male and female attachment avoidance, as well as male attachment anxiety, predicted lower dyadic trust, which in turn predicted lower relationship satisfaction. These results add to the current literature, suggesting important gender differences in the effects attachment has on overall relationship satisfaction.     

Saccadic eye movements: what do they tell us about aging cognition?

Although the relationship between age-related cognitive decline and saccadic eye movement (SEM) deficits has been outlined, specific cognitive alterations underlying age-related changes in saccadic performance remain unclear. This study attempted to better understand the nature of aging effects on SEMs. We compared SEMs in younger and older adults in prosaccade (PS) and antisaccade (AS) tasks under gap, step, and overlap conditions. We also examined relationships between these performances and several neuropsychological scores. Twenty-eight younger adults (YA), 24 older adults under 65 years (OA_<65) and 24 over 65 years (OA_>65) of age completed a neuropsychological evaluation, PS and AS tasks. Our results showed that latencies, AS cost, time to correct AS errors, and uncorrected AS, increased with aging. YA showed higher overlap effects than OA_>65 and OA_<65. Importantly, correlations and regressions revealed close relationships not only between latencies and processing speed measures but also between the AS cost and the inhibition process measures. Correct saccades and the time to correct AS errors were closely related to the inhibition process and cognitive flexibility measures. These findings suggest that the progressive age-related decline of processing speed and executive attention are associated with, and can be highlighted though SEMs in PS and AS tasks.
