The administration of the ryanodine receptor (RyR) agonist 4-Cmc (0.003-9 nmol per mouse intracerebroventricularly [i.c.v.]) ameliorated memory functions, whereas the RyR antagonist ryanodine (0.0001-1 nmol per mouse i.c.v.) induced amnesia in the mouse passive avoidance test. The role of the type 1, 2, and 3 RyR isoforms in memory processes was then evaluated by inhibiting the expression of the three RyR proteins in the mouse brain. A selective knockdown of the RyR isoforms was obtained by the i.c.v. administration of antisense oligonucleotides (aODNs) complementary to the sequence of RyR1, RyR2 and RyR3 proteins, as demonstrated by immunoblotting experiments. RyR1 (5-9 nmol per mouse i.c.v.) knockdown mice did not show any memory dysfunction. Conversely, RyR2 (1-7 nmol per mouse i.c.v.) and RyR3 (1-7 nmol per mouse i.c.v.) knockdown animals showed an impairment of memory processes. This detrimental effect was temporary and reversible, disappearing 7 d after the end of the aODN treatment. At the highest effective doses, none of the compounds used impaired motor coordination, as revealed by the rota rod test, nor modified spontaneous mobility and inspection activity, as revealed by the hole-board test. In conclusion, the lack of any involvement of cerebral RyR1 was demonstrated. These findings also showed the involvement of type 2 and type 3 RyR in the modulation of memory functions identifying these cerebral RyR isoforms as critical targets underlying memory processes. 相似文献

Current guidelines indicate that therapeutic interactions must be in the client's primary language. This article addresses the ethical dilemmas faced by monolingual clinicians and researchers who must assess the foreign language competence of an interpreter. Guidelines are proposed for assessing language competence of staff in clinical and research settings. Las directrices actuales indican que la interacción terapéutica debe tomar lugar en el primer idioma del cliente. Este artículo trata los dilemas éticos que confrontan los clínicos e investigadores monolingües que tienen que asesorar la competencia linguística de un intérprete. Se proponen directrices para el asesoramiento linguístico de personal en escenarios clínicos y de investigación. 相似文献

Feedback is an important self-regulatory process that affects task effort and subsequent performance. Benefits of positive feedback for list recall have been explored in research on goals and feedback, but the effect of negative feedback on memory has rarely been studied. The current research extends knowledge of memory and feedback effects by investigating face–name association memory and by examining the potential mediation of feedback effects, in younger and older adults, through self-evaluative beliefs. Beliefs were assessed before and after name recognition and name recall testing. Repeated presentation of false positive feedback was compared to false negative feedback and a no feedback condition. Results showed that memory self-efficacy declined over time for participants in the negative and no feedback conditions but was sustained for those receiving positive feedback. Furthermore, participants who received negative feedback felt older after testing than before testing. For name recall, the positive feedback group outperformed the negative feedback and no feedback groups combined, with no age interactions. The observed feedback-related effects on memory were fully mediated by changes in memory self-efficacy. These findings advance our understanding of how beliefs are related to feedback in memory and inform future studies examining the importance of self-regulation in memory. 相似文献

We aimed to bring a developmental perspective to metacognitive theory. The metacognitive model (MCM) was originally developed for adults. However, an increasing number of studies demonstrate the MCM is relevant to child anxiety. Therefore, it is important to understand the origins of anxiety-specific metacognitions. Given the role experiences of controlling parenting play in maintaining and perhaps forming anxious cognitions or a cognitive vulnerability we focused on maternal behavioral and psychological control. Using a cross-sectional design, Danish school children (9–17 years old; N?=?1062) rated their levels of anxiety and anxiety-specific metacognitions, and their mothers' controlling behavior. Child-perceived maternal psychological control was positively correlated with each anxiety specific metacognition (positive and negative worry beliefs, cognitive confidence, need to control, and cognitive self-consciousness). Child-perceived autonomy-granting was negatively correlated with all metacognitions except cognitive self-consciousness. Child perceived maternal psychological control was indirectly associated with anxiety via total metacognitions. Child-perceived autonomy-granting, but not psychological control, was directly related to anxiety. Given the differential findings for psychological control and autonomy-granting, we suggest that specific types of parenting behavior may be related to specific elements of (meta-) cognitive vulnerability. Our findings are theoretically important because they propose maternal psychological control is an environmental factor that may play a role in the development of a metacognitive vulnerability related to anxiety. A potential clinical implication of our findings is that metacognitive therapy for children should include a parental component. 相似文献

This report examines the measurement invariance of the Personal Well-being Index with 8 items (PWI-8). University students (N = 5731) from 26 countries completed the measure either through paper and pencil or electronic mode. We examined uni-dimensional structure of PWI and performed a Multi-group CFA to assess the measurement invariance across the 26 countries, using conventional approach and the alignment procedure. The findings provide evidence of configural and partial metric invariance, as well as partial scalar invariance across samples. The findings suggest that PWI-8 can be used to examine correlates of life satisfaction across all included countries, however it is impossible to compare raw scores across countries. 相似文献

In this study we examined the relations between insecure attachment styles, commitment and behavioral problems, focusing on
the unique and common contribution that avoidant and anxious styles and commitment made to internalizing and externalizing
problems. 535 adolescents, 267 boys and 268 girls, aged from 16 to 18 years, completed self-report measures of attachment,
identity and problem behaviors. The data showed that both internalizing and externalizing problems were positively related
to insecure attachment styles and negatively to commitment. Results supported a unique contribution of both insecure styles
to the prediction of internalizing and externalizing problems, whereas commitment negatively predicted only internalizing
behaviors. The data supported a joint effect of avoidant attachment and commitment such that commitment contributed to moderate
the display of internalizing and externalizing problems among avoidant adolescents. 相似文献

One of the first to criticize the verifiability theory of meaning embraced by logical empiricists, Reichenbach ties the significance
of scientific statements to their predictive character, which offers the condition for their testability. While identifying
prediction as the task of scientific knowledge, Reichenbach assigns induction a pivotal role, and regards the theory of knowledge
as a theory of prediction based on induction. Reichenbach’s inductivism is grounded on the frequency notion of probability,
of which he prompts a more flexible version than that of Richard von Mises. Unlike von Mises, Reichenbach attempts to account
for single case probabilities, and entertains a restricted notion of randomness, more suitable for practical purposes. Moreover,
Reichenbach developed a theory of induction, absent from von Mises’s perspective, and argued for the justification of induction.
This article outlines the main traits of Reichenbach’s inductivism, with special reference to his book Experience and prediction. 相似文献

Despite the high co-occurrence of alcohol consumption and gambling, few studies have investigated alcohol use changes during gambling treatment. Using latent growth modeling, we examined weekly alcohol use trajectories of treatment-seeking pathological gamblers across 36 weeks, allowing rates of change to differ across the 12-week pretreatment, during-treatment and posttreatment periods. For these secondary data analyses, we retained drinking gamblers (N = 163) from a combined sample of two randomized clinical trials for the treatment of pathological gambling. Results indicated a decrease in alcohol use corresponding with treatment entry and maintenance of less drinking during treatment and posttreatment. Despite these decreases in alcohol use overall, 31% (50 of 163) of participants exhibited risky drinking during the treatment or posttreatment periods. Gender, age, at-risk drinking (at any point in the 36-week interval), baseline gambling severity, treatment condition, and gambling during treatment predicted latent alcohol use growth factors. Although entry into gambling treatment was temporally associated with reductions in alcohol use in this retrospective analysis, a substantial portion of the sample exhibited at-risk drinking after treatment entry, suggesting that interventions targeting reductions in alcohol use may be useful for this population. 相似文献
