Effects of male postpartum depression on father–infant interaction: The mediating role of face processing

It is estimated that postpartum depression affects up to 25% of men. Despite such high prevalence, the majority of studies on postpartum depression are focused on mothers, and the role of paternal depression and its effects on infant development have been overlooked by researchers and clinicians. The present study aimed to fill this gap by investigating the effect of paternal postpartum depression on father–infant interactions. In addition, we examined whether differences in face recognition mediated the effects of paternal postpartum depression on father–infant interactions. A total of 61 father–infant dyads (17 postpartum depression, 44 controls) took part in the study. Results revealed that compared to controls, fathers with postpartum depression had a worse pattern of interaction with their infants on measures of responsiveness, mood, and sensitivity; they also had greater difficulty in recognizing happy adult faces, but greater facility in recognizing sad adult faces. Depressed fathers attributed greater intensities to sad adult and infant faces. The tendency to attribute greater intensity to sad adult faces was confirmed as a partial mediator of the effect of paternal postpartum depression on measures of father responsiveness and as a full mediator of the effects of paternal depression on father sensitivity. Clinical implications and suggestions for further studies are discussed.     

Attachment and coparenting representations in men during the transition to parenthood

Coparenting is based on parents’ representations of themselves as coparents. Attachment theory can be a useful framework to understand the way that different coparenting representations are developed during the transition to parenthood. This study aimed to analyze the association between men's attachment and coparenting representations at the first trimester of pregnancy and from the first trimester of pregnancy to 6 months’ postpartum. A sample of 86 men was recruited and completed self-report measures of attachment and coparenting representations at the first and third trimester of pregnancy and at 1 and 6 months’ postpartum. At the first trimester of pregnancy, higher attachment avoidance was associated with higher lack of coparenting support. From the first trimester of pregnancy to 6 months’ postpartum, higher attachment avoidance was associated with (a) a steeper increase on lack of coparenting support, (b) an increase on coparenting conflict (while low attachment avoidance was associated with a decrease), and (c) a lower decrease on coparenting disagreement. This study may contribute to coparenting research by showing new evidence on attachment theory as a useful framework to understand how different coparenting representations are developed in men during the transition to parenthood.     

The Ecology of Experiences for African American Women in Clinical Doctoral Programs

African American women must navigate higher education, in particular, clinical doctoral programs, as a gendered racial minority. These women often endure multiple levels of discrimination to obtain their degree. Findings of this study highlight these experiences and suggest the importance of increasing supports for African American women in clinical doctoral programs. Practices and supports should be put in place so that students of color are not marginalized because of their race. Las mujeres afroamericanas tienen que pasar por la educación superior, y particularmente en programas de doctorado clínico, como una minoría racial y de sexo. Estas mujeres sufren con frecuencia múltiples niveles de discriminación para poder obtener su titulación. Los hallazgos de este estudio destacan estas experiencias y sugieren la importancia de incrementar los apoyos para mujeres afroamericanas en programas de doctorado clínico. Deberían implementarse prácticas y apoyos para que las estudiantes de color no sean marginadas por su raza.     

Idealizations and Concretizations in Laws and Explanations in Physics

The paper tries to provide an alternative to Hempel’s approach to scientific laws and scientific explanation as given in his D-N model. It starts with a brief exposition of the main characteristics of Hempel’s approach to deductive explanations based on universal scientific laws and analyzes the problems and paradoxes inherent in this approach. By way of solution, it analyzes the scientific laws and explanations in classical mechanics and then reconstructs the corresponding models of explanation, as well as the types of scientific laws appearing in it. Finally, it compares this reconstruction with the approaches of J. Woodward and C. Hitchcock, C. Liu and with the views of M. Thalos on analytic mechanics.

STRUCTURES OF EVIL ENCOUNTERED IN PASTORAL COUNSELING

This essay explores some relationships between social structures or systems and the internal psychological structures or systems of individuals. After defining evil, pastoral counseling, and structures or systems, I present examples of persons affected by social systems of power who have sought counseling. I present a form of counseling known as Internal Family System Therapy (IFS) and show with an extended example how I have worked with clients using this approach. In this process the client is guided to use “Self‐leadership” in healing and transforming inner conflict between various subpersonalities or “parts.” I then compare the IFS approach to one used by mediators in community conflict transformation and peacebuilding.     

Trace administration of vitamin E can retrieve and prevent UV-irradiation- and metal exposure-induced memory deficits in nematode Caenorhabditis elegans

Vitamin E (α-tocopherol), a lipid-soluble anti-oxidant, prevents the uncontrolled propagation of lipid peroxidation by free radicals. Nevertheless, there is weak or no evidence of a protective effect of previous vitamin E intake on cognitive function in humans. In the present study, we explored the thermosensation model to investigate the possible effects of vitamin E administration on memory behaviors in Caenorhabditis elegans. Administration of 100 and 200 μg/mL of vitamin E had no significant effects on the memory for different time intervals, whereas relatively high concentration (400 μg/mL) of vitamin E exposure shortened the extinction period of the association paradigm (food at 20 °C). Following the UV-irradiation, post-treatment with 200 μg/mL of vitamin E not only retrieved the UV-irradiation-induced memory deficits, but also enhanced the memory functions in UV-irradiating animals. Post-treatment with trace vitamin E could also ameliorate the memory deficits in metal (Al or Pb) exposed worms. In addition, pre-treatment with 200 μg/mL of vitamin E could effectively prevent the occurrence of memory deficits induced by metal exposure and UV-irradiation. Therefore, the close association may exist between trace dietary vitamin E intake and memory behaviors, and a specific response mechanism may be activated after the administration of vitamin E in stress-exposed animals. Moreover, treatment with 200 μg/mL of vitamin E could restore the memory deficits formed in the ncs-1 mutant worms, suggesting that exogenous treatment with trace vitamin E can largely mimic the function of NCS-1 in regulating the memory for thermosensation.     

Apodemus sylvaticus (LOXT) is a suitable mouse strain for testing spatial memory retention in the Morris water maze

Information on the difference in cognitive function between laboratory and wild-caught mice is anecdotal and this question has not been systematically studied. Moreover, studying a wild-caught mouse strain per se may add information to the repertoire of mouse strains available. We aimed to study spatial memory in a wild mouse strain (Apodemus sylvaticus, AS) as compared to two individual laboratory mouse strains.Male AS (n = 20), CD1 (n = 19) and C57BL/6J mice (n = 19), 12–14 weeks old, were used in the experiments. The Morris water maze (MWM) was used for determination of spatial memory and time spent in the target quadrant at time points 5 (D5) and 12 days (D12) was evaluated. During the acquisition phase latency to reach the platform and path length to reach the platform was evaluated.Following four training days on day 5 (D5), time spent in the target quadrant was highest in AS > CD1 > C57BL/6J (P < 0.006). On day 12 (D12), time spent in the target quadrant was significantly higher in AS than in both other strains (P < 0.001).All animals learned the task and during the acquisition phase, latency to reach the platform as well as path length decreased significantly in AS.It is concluded that the AS is the most suitable strain for the evaluation of spatial memory in the MWM and is presenting with memory retention superior to laboratory mouse strains CD1 and C57BL/6J.     

AI,ME AND LEWIS (ABELIAN IMPLICATION,MATERIAL EQUIVALENCE AND C I LEWIS 1920)

C I Lewis showed up Down Under in 2005, in e-mails initiated by Allen Hazen of Melbourne. Their topic was the system Hazen called FL (a Funny Logic), axiomatized in passing in Lewis 1921. I show that FL is the system MEN of material equivalence with negation. But negation plays no special role in MEN. Symbolizing equivalence with → and defining ∼A inferentially as A→f, the theorems of MEN are just those of the underlying theory ME of pure material equivalence. This accords with the treatment of negation in the Abelian l-group logic A of Meyer and Slaney (Abelian logic. Abstract, Journal of Symbolic Logic 46, 425–426, 1981), which also defines ∼A inferentially with no special conditions on f. The paper then concentrates on the pure implicational part AI of A, the simple logic of Abelian groups. The integers Z were known to be characteristic for AI, with every non-theorem B refutable mod some Zn for finite n. Noted here is that AI is pre-tabular, having the Scroggs property that every proper extension SI of AI, closed under substitution and detachment, has some finite Zn as its characteristic matrix. In particular FL is the extension for which n = 2 (Lewis, The structure of logic and its relation to other systems. The Journal of Philosophy 18, 505–516, 1921; Meyer and Slaney, Abelian logic.

Norman, eds., Paraconsistent logic: essays on the inconsistent, Philosophica Verlag, Munich, pp. 245–288, 1989).

Clinique des raisonnements collectifs accomplis par des dyades réussissant la tâche de sélection de Wason dans sa version abstraite

We study the resolution of the abstract selection task in a context of cooperative dialogue. We make 59 students achieve the task individually and 32 dyads (recording their dialogue). In accordance with the literature, the dyads perform significantly better than the students alone. We then highlight the logical strategies at work in the conversations of the four dyads which succeed in the task with a theory of the logical form of the interlocutory events such as they arise phenomenally: the interlocutory logic. These strategies are emergent products of the dialogue since no member of the dyads knows them before the interaction. It is surely by supporting the emergence of such joint cognitions that the interaction is a factor of cognitive progress.
