Sounds change four-dot masking

The temporal occurrence of a flash can be shifted towards a slightly offset sound (temporal ventriloquism). Here we examined whether four-dot masking is affected by this phenomenon. In Experiment 1, we demonstrate that there is release from four-dot masking if two sounds - one before the target and one after the mask - are presented at ∼100 ms intervals rather than at ∼0 ms intervals or a silent condition. In Experiment 2, we show that the release from masking originates from an alerting effect of the first sound, and a temporal ventriloquist effect from the first and second sounds that lengthened the perceived interval between target and mask, thereby leaving more time for the target to consolidate. Results thus show that sounds penetrate the visual system at more than one level.     

Visual objects can potentiate a grasping neural simulation which interferes with manual response execution

Previous studies on visuomotor priming have provided insufficient information to determine whether the reach-to-grasp potentiation of a non-target object produces a specific effect during response execution. In order to answer this question, subjects were instructed to reach and grasp a response device with either a power or a precision grip, depending on whether the stimulus they saw was empty or full. Stimuli consisted of containers (graspable with either a power or a precision grip), with non-graspable stimuli added as a control condition (geometrical shapes). The image of the non-target object was removed during the execution phase. Results demonstrate slower execution responses related to motor incompatibility, though conversely, no faster responses with motor compatibility. Moreover, any visuomotor priming effect required that the container be displayed during response execution. These data suggest that during response execution, motor incompatibility produces a disruptive effect likely due to competition between two cerebral events: motor control of the actual response execution and visual object reach-to-grasp neural simulation.     

A Longitudinal Study of Parental Depressive Symptoms and Coparenting in the First 18 Months

Although the negative impact of postpartum depression on parenting behaviors has been well established—albeit separately—for mothers and fathers, the respective and joint impact of both parents' mood on family‐group interactive behaviors, such as coparenting support and conflict behaviors between the parents, have not yet been investigated. The aim of this study was to examine the association between parental depressive symptoms and coparenting behaviors in a low‐risk sample of families with infants, exploring reciprocity between the variables, as well as gender differences between mothers and fathers regarding these links. At 3 (T1), 9 (T2), and 18 months postpartum (T3), we assessed both parents' depressive symptoms with a self‐report questionnaire and observed coparenting support and conflict during triadic mother–father–child interactions. The results revealed that higher maternal depressive symptoms at T1 were associated with lower support at T1 and T2. Conflict at T3 was associated with higher maternal depressive symptoms at T3 and, more surprisingly, with less depressive symptoms in mothers at T2 and fathers at T3. Cross‐lagged associations suggested that parental depressive symptoms were more likely to influence coparenting than the reverse. Moreover, maternal depressive symptoms were more likely to be linked to coparenting behaviors than were paternal depressive symptoms. These results confirm that parental—mostly maternal—depressive symptoms, even of mild intensity, may jeopardize the development of healthy family‐level relations, which previous research has shown to be crucial for child development.     

Self‐affirmation,political value congruence,and support for refugees

This research tested the potential for self‐affirmation on left‐ and right‐wing political values to increase behavioral intentions to provide help and assistance to refugees. We present a pilot study defining left‐ and right‐wing values, and a main study in which participants completed either a self‐affirmation task, a group‐affirmation task, or participated in a control condition on values that were either congruent or incongruent with their own political views. Results show that left‐wing oriented participants showed more supportive intentions in the self‐affirmation condition compared to the group‐affirmation and control conditions, independent of values congruency. In contrast, right‐wing participants showed more supportive intentions in the self‐affirmation condition, but only when they affirmed on values that were congruent with their own political views.     

Change in physical and psychological health over time in patients with cardiovascular disease: on the benefits of being self-determined,physically active,and eating well

This study tested a longitudinal model examining the roles of motivation and perceived competence in the prediction of physical activity (PA) and healthy eating (HE) in individuals with cardiovascular diseases, and the effects of adopting these behaviors on individuals’ health. Participants completed measures of global motivation (baseline), contextual motivation and perceived competence for PA and HE (3 months), and self-reports of PA and HE behaviors (6 months). Physiological indicators and life satisfaction were assessed at the baseline and at 12 months. Structural equation modeling supported that individuals with self-determined motivation (SDM) were more likely to feel competent in changing their lifestyle and to engage in moderate and strenuous (vs. mild) exercise and HE behaviors, which had beneficial effects on individuals’ physiological and psychological health. This research confirms the respective roles of SDM and perceived competence in the health behavior change process and emphasizes the key function of SDM in the adherence of healthy behaviors over time.     

The contribution of “cool” and “hot” components of decision-making in adolescence: Implications for developmental psychopathology

Impairments in either “cool” or “hot” processes may represent two pathways to deficient decision-making. Whereas cool processes are associated with cognitive and rational decisions, hot processes are associated with emotional, affective, and visceral processes. In this study, 168 boys were administered a card-playing task at ages 13 and 14 years to assess response perseveration. This task was designed to initially reward playing and gradually associate playing with punishment. Measures of subjective ordering (cool processes) and neuroticism (hot processes) at age 13 years were used to examine how these individual characteristics relate to perseveration over time. A decrease in perseveration from age 13 to 14 was associated with cool processes whereas hot processes were associated with response perseveration only over time. A complementary but simultaneous assessment of cool and hot processes, such as neuropsychological and personality tests, could facilitate treatment planning of children with behavioral problems.
