Although decades of research have documented that children whose parents have a history of Major Depressive Disorder (MDD) are at a higher risk of developing depression themselves, not all of these children go on to develop depression themselves, thus highlighting the need to understand potential moderators of risk. The current study examined whether child emotion regulation, specifically, the use of cognitive reappraisal and suppression, moderated the link between parent and child depression. We recruited 458 parents and their children between the ages of 7–11 from the community. The majority of children were Caucasian (74.2%) and approximately half were girls (46.1%). Among children with a parent history of MDD, those who reported using cognitive reappraisal more frequently were less likely to have a history of depressive diagnoses themselves and had higher current levels of positive affect. Although children’s use of suppression was not associated with their levels of depressive symptoms among children with a parent history of MDD, higher levels of suppression were related to higher levels of depressive symptoms among children with no parent history of MDD. These findings suggest that, among children with a history of parent depression, children’s use of cognitive reappraisal may influence their own risk for developing depression and highlights the potential utility of early interventions that focus on improving the use of emotion regulation strategies like cognitive reappraisal among children of depressed parents. 相似文献

Recent advancements in Bayesian modeling have allowed for likelihood-free posterior estimation. Such estimation techniques are crucial to the understanding of simulation-based models, whose likelihood functions may be difficult or even impossible to derive. However, current approaches are limited by their dependence on sufficient statistics and/or tolerance thresholds. In this article, we provide a new approach that requires no summary statistics, error terms, or thresholds and is generalizable to all models in psychology that can be simulated. We use our algorithm to fit a variety of cognitive models with known likelihood functions to ensure the accuracy of our approach. We then apply our method to two real-world examples to illustrate the types of complex problems our method solves. In the first example, we fit an error-correcting criterion model of signal detection, whose criterion dynamically adjusts after every trial. We then fit two models of choice response time to experimental data: the linear ballistic accumulator model, which has a known likelihood, and the leaky competing accumulator model, whose likelihood is intractable. The estimated posterior distributions of the two models allow for direct parameter interpretation and model comparison by means of conventional Bayesian statistics—a feat that was not previously possible. 相似文献

Cognitive behavior therapy (CBT) has been demonstrated in a number of randomized controlled trials to be efficacious as an adjunctive treatment for psychotic disorders. Emerging evidence suggests the usefulness of CBT interventions that incorporate acceptance/mindfulness-based approaches for this population. The current study extended previous research by Bach and Hayes (2002. The use of Acceptance and Commitment Therapy to prevent the rehospitalization of psychotic patients: A randomized controlled trial. Journal of Consulting and Clinical Psychology, 70, 1129-1139) using Acceptance and Commitment Therapy (ACT) in the treatment of psychosis. Psychiatric inpatients with psychotic symptoms were randomly assigned to enhanced treatment as usual (ETAU) or ETAU plus individual sessions of ACT. At discharge from the hospital, results suggested short-term advantages in the ACT group in affective symptoms, overall improvement, social impairment, and distress associated with hallucinations. In addition, more participants in the ACT condition reached clinically significant symptom improvement at discharge. Although 4-month rehospitalization rates were lower in the ACT group, these differences did not reach statistical significance. Decreases in the believability of hallucinations during treatment were observed only in the ACT condition, and change in believability was strongly associated with change in distress after controlling for change in the frequency of hallucinations. Results are interpreted as largely consistent with the findings of Bach and Hayes and warrant further investigations with larger samples. 相似文献

The nature of object representation in working memory is vital to establishing the capacity of working memory, which in turn shapes the limits of visual cognition and awareness. Although current theories discuss whether representations in working memory are feature-based or object-based, no theory has considered the role of past experience. However, work with humans and non-human primates suggests that once participants learn which features are important for category membership, these diagnostic features become more salient than non-diagnostic features in long-term memory and object recognition. Critically, the brain areas involved in this diagnosticity effect are also recruited during working memory tasks. We report two experiments testing whether a diagnosticity effect exists in working memory; and whether it is present when visual information is encoded into working memory, or if it is the result of maintenance within working memory. Results showed a diagnosticity effect which was present at encoding. Maintenance did not influence the nature of object representation in working memory. These findings show that the meaning we glean from our past experience has a profound influence on the nature of object representation in working memory. 相似文献

Learning tasks are typically thought to be either hippocampal-dependent (impaired by hippocampal lesions) or hippocampal-independent (indifferent to hippocampal lesions). Here, we show that conditioned taste aversion (CTA) learning fits into neither of these categories. Rats were trained to avoid two taste stimuli, one novel and one familiar. Muscimol infused through surgically implanted intracranial cannulae temporarily inactivated the dorsal hippocampus during familiarization, subsequent CTA training, or both. As shown previously, hippocampal inactivation during familiarization enhanced the effect of that familiarization on learning (i.e., hippocampal inactivation enhanced latent inhibition of CTA); more novel and surprising, however, was the finding that hippocampal inactivation during training sessions strongly enhanced CTA learning itself. These phenomena were not caused by specific aspects of our infusion technique--muscimol infusions into the hippocampus during familiarization sessions did not cause CTAs, muscimol infusions into gustatory cortex caused the expected attenuation of CTA, and hippocampal inactivation caused the expected attenuation of spatial learning. Thus, we suggest that hippocampal memory processes interfere with the specific learning mechanisms underlying CTA, and more generally that multiple memory systems do not operate independently. 相似文献

This paper describes a transducer that allows for the concurrent recording of outer eyelid closure on both the left and the right eyes of a rabbit. The device makes use of voltage induced across a current-carrying conductor when the conductor is exposed to a magnetic field perpendicular to its axis (the Hall effect). The transducer is relatively compact, inexpensive, and allows the animal to be loosely restrained. 相似文献

The Telemetric Topography Device (TTD) introduces new technology to the measurement of cigarette smoking topography that has advantages over existing instruments. It consists of a 90.8-g miniature vacuum transducer coupled to an FM transmitter contained within a 11/4-in.-diameter × 41/4-in. free-standing plastic cylinder. As a subject smokes through a modified commercial cigarette holder, the TTD transmits a tone proportional to the vacuum pressure change in the cylinder. Received tones are converted to voltage data and then digitized by an A/D board in a personal computer. This information can either be displayed and stored on line or recorded on audio tape and digitized during playback. The TTD has no visible electronic parts, thereby minimizing subjects’ awareness of monitoring. 相似文献

The essence of spiritual counselling lies in the formal or informal teaching of meditation, where we turn away from the delusions of any achievement either psychological or material. These delusions, deeply embedded in psychotherapy and counselling, are essentially destructive. Real counselling lies in giving up ambitions and ideologies, not in acquiring more. Meditation can help us to live more fully in the present time. 相似文献

To determine whether L-type voltage-gated calcium channels (L-VGCCs) are required for remote memory consolidation, we generated conditional knockout mice in which the L-VGCC isoform Ca(V)1.2 was postnatally deleted in the hippocampus and cortex. In the Morris water maze, both Ca(V)1.2 conditional knockout mice (Ca(V)1.2(cKO)) and control littermates displayed a marked decrease in escape latencies and performed equally well on probe trials administered during training. In distinct contrast to their performance during training, Ca(V)1.2(cKO) mice exhibited significant impairments in spatial memory when examined 30 d after training, suggesting that Ca(V)1.2 plays a critical role in consolidation of remote spatial memories. 相似文献
