Parental burnout refers to loss of energy and pleasure in the parental role. It is predictive of psychopathological outcomes in parents and dysfunctional parenting behaviors. Support of parental duties is central to alleviation of parental burden and prevention of burnout. Coparenting is the concept related to interparental mutual support in rearing a child. However, the links between coparenting and parental burnout have yet to be assessed. We thus aimed in this study to assess which dimensions of coparenting are linked with parental burnout. A total of 306 participants from the French-speaking part of Switzerland (120 fathers, 186 mothers) completed online questionnaires about parental burnout, their coparental relationship, and sociodemographic characteristics. We performed hierarchical regressions, entering sociodemographic characteristics in a first block and coparenting dimensions in a second block. Results showed that (i) a higher number of children and having younger children are linked to higher burnout; (ii) coparenting exposure to conflict is related to higher burnout, whereas endorsement of the partner's parenting is related to lower burnout; and (iii) no interaction effect occurs between sociodemographic characteristics and coparenting variables. Coparenting thus significantly contributes to the occurrence of burnout syndrome. Working on the coparental relationship preventively in parental educational programs or at a relational systemic level in therapy may help prevent burnout. Treating one parent only may not be sufficient to alleviate burnout, as negative coparenting could counter the effect of individual therapy. 相似文献

Creativity is a fundamental human accomplishment from scientific advances to composing music. The left dorsolateral prefrontal cortex (DLPFC) and inferior frontal gyrus (IFG) are important metacontrol hubs in flexibility and persistence brain states, respectively. Those hubs are related to divergent thinking, insight problem-solving, and convergent thinking. In this double-blind, between-subjects study, 81 healthy participants were randomly assigned to one of three groups (n = 27) that received a combined transcranial direct current stimulation–transcranial random noise stimulation (tDCS-tRNS) protocol with the anode over the left DLPFC and cathode over the left IFG (+DLPFC−IFG), the opposite montage (−DLPFC+IFG), and a sham group (+DLPFC−IFG). Both active tDCS-tRNS groups received 20 min of 1 mA tDCS with 1 mA (100–500 Hz) tRNS. Creativity was assessed before (baseline) and during stimulation with the Unusual Uses, Picture Completion (PC), Remote Association test (RAT), Matchstick Arithmetic (MA), and Nine-dot (ND) problems. Only the +DLPFC−IFG group had significantly higher scores compared with sham in the RAT (p = .009), PC fluency (p = .018), PC originality (p = .007), ND (p = .007), and MA (p = .032). Overall, −DLPFC+IFG had greater scores in all creativity tests compared with sham. Implications from the metacontrol theory are discussed. 相似文献

In Dutch noun phrases like “het boek” (the book) or “de kat” (the cat), the definite article (het or de) depends on the noun's grammatical gender (neuter or non-neuter). Schriefers reported that the production of a noun phrase
like “het rode bed” (“the red bed”) in response to a colored picture takes less time when the picture is accompanied by a distractor word of
congruent gender (e.g., “huis,” a het-word) than when it is accompanied by a word of incongruent gender (e.g., “hand,” a de-word). In three experiments we explored the characteristics of this gender-congruency effect. The following conclusions were
reached. First, the gender-congruency effect is a rather robust phenomenon. Second, with the exception of a small effect in
Exp. 2, no evidence was obtained for a gender-congruency effect when subjects were required to produce a single noun in response
to a picture (e.g., “bed”). Third, the gender-congruency effect decreases with a decreasing familiarity of the distractor word. Implications for models
of word production are discussed.

The Revision Theory of Truth (Gupta/Belnap 93) has been challenged in A. M. Yaqb's recent book The Liar Speaks the Truth. Yaqb suggests some non-trivial changes in the original theory — changing the limit rule — to avoid certain artifacts. In this paper it is shown that the proposed changes are not sufficient, i.e., Yaqb's system also produces artifacts. An alternative solution is proposed and the relation between it and Yaqb's solution is explored. 相似文献

Ability to stand alone and processing of open-class and closed-class words: Isolation versus context
A. René Schmauder 《Journal of psycholinguistic research》1996,25(4):443-481
Four experiments investigating processing of closed-class and open-class words in isolation and in sentence contexts are reported. Taft (1990) reported that closed-class words which could not meaningfully stand alone and open-class words which could not meaningfully stand alone incurred longer lexical decision responses than did control words. Taft also reported that closed-class and open-class words which could stand alone meaningfully were not associated with longer lexical decision responses than were control words. Experiments 1 and 2 replicated Taft 's effect of ability to stand alone on lexical decision responses to closed-class and open-class words presented in isolation. In Experiments 3 and 4, the same lexical decision targets were presented as part of semantically neutral context sentences in a moving window paradigm. The stand-alone effect was not present in Experiments 3 and 4. The results suggest Toft's conclusion that meaningfulness of a word influences lexical decision needs revision. An explanation is provided according to which support from message level and syntactic and lexical sources in sentence contexts influence words' perceived “meaningfulness.” 相似文献

This paper proposes a distinction between primary generalization (transfer from stored exemplars to perceived targets) and secondary generalization (transfer from inferred abstractions to perceived targets). This distinction is embodied in the parallel rule activation and rule synthesis (PRAS) model, a production model capable of exemplar-based and abstraction-based categorization. As an exemplar model, the PRAS model is related to the generalized context model (Nosofsky, 1984). Exemplars are stored in memory encoded as condition-action rules. Working as an exemplar-based model, rules are activated on the basis of their strength and their similarity to the current to-be-categorized instance. Similarity between a target and a stored exemplar is weighted for attention to the dimensions of the psychological space. Depending on the value of a special parameter, the PRAS model is also able to operate as an abstraction model. In the latter case, it attempts to construct generalizing productions, which are activated according to the same rules as the exemplar-specific rules. The model is described in detail. It is applied to a number of important observations described in the research literature, and an experiment is reported that tested the usefulness of the proposed secondary-generalization mechanism. Finally, the discussion elaborates on the implications of the present study for further research. 相似文献

Semantics are given for modal extensions of relevant logics based on the kind of frames introduced in [7]. By means of a simple recipe we may obtain from a class FRM (L) of unreduced frames characterising a (non-modal) logic L, frame-classes FRM
(L.M) characterising conjunctively regular modal extensions L.M of L. By displaying an incompleteness phenomenon, it is shown how the recipe fails when reduced frames are under consideration. 相似文献

The present study was aimed at replicating the results of a previous work on sex differences and electrodermal asymmetry from
our laboratory (Román,et al. 1987). Skin conductance was bilaterally recorded in a sample of 44 dextral volunteers (22 males and 22 females) during a
stimulus-free period, and the performance of two tasks (verbal and spatial). Subjects were grouped into two groups of right-hand
and left-hand dominance in their electrodermal responses (EDRs) in accordance with their laterality coefficient scores at
rest. During the tasks subjects appeareed clearly differentiated by their lateralization in the magnitude and frequency of
EDRs independently of gender: right-hand responders showed higher electrodermal activity on their right hand, while left-hand
responders showed higher electrodermal activity on their left hand. Sex differences were not observed within each responsiveness
pattern. The orientation of phasic electrodermal changes remained constant throughout the different conditions. 相似文献
