The present study examined psychophysiological reactivity to emotional stimuli related and non-related to sleep in people with primary insomnia (PPI) and in good sleepers (GS). Twenty-one PPI and 18 GS were presented with five blocks of neutral, negative, positive, sleep-related negative and sleep-related positive pictures. During the presentation of the pictures, facial electromyography (EMG) of the corrugator and the zygomatic muscles, heart rate (HR) and cardiac vagal tone (CVT) were recorded. Subjective ratings of the stimuli were also collected. We found that only PPI exhibited greater inhibition of the corrugator activity in response to sleep-related positive stimuli compared to the other blocks of stimuli. Furthermore, PPI rated the sleep-related negative stimuli as more unpleasant and arousing and showed higher CVT in response to all stimuli as compared to GS. Results were interpreted as indicating that PPI exhibit craving for sleep-related positive stimuli, and also hyper-arousability in response to sleep-related negative stimuli, as compared to GS. Our results suggest that psychological treatment of insomnia could benefit by the inclusion of strategies dealing with emotional processes linked with sleep processes. 相似文献

The Cognitive-Affective Processing System (CAPS) was used to examine effortful control (EC) as a moderator of daily interpersonal behavior. Participants (N = 240) were nonclinical young adults who completed a 7-day event-contingent experience sampling study of interpersonal perception and affect. Multilevel linear models indicated that EC moderated within-person covariation of interpersonal warmth and affect activation; high EC individuals reported greater momentary warm behaviors when perceiving others as affectively activated. EC also amplified between-person covariation of interpersonal warmth between self and others; high EC individuals generally responded to perceptions of another's warmth with a greater degree of warm behavior. Varying levels of EC predict responses to interpersonal perceptions and affect in daily life, suggesting an important dimension for interpersonal functioning. 相似文献

Aversive memory reactivation engages in the amygdala only some neurotransmitters involved in consolidation 下载免费PDF全文

Consolidation refers to item stabilization in long-term memory. Retrieval renders a consolidated memory sensitive, and a "reconsolidation" process has been hypothesized to keep the original memory persistent. Some authors could not detect this phenomenon. Here we show that retrieved contextual fear memory is vulnerable to amnesic treatments and that the amygdala is critically involved. Cholinergic and histaminergic systems seem to modulate only consolidation, whereas cannabinoids are involved in both consolidation and reactivation. The lability of retrieved memory affords opportunities to treat disorders such as phobias, post-traumatic stress, or chronic pain, and these results help searching for appropriate therapeutic targets. 相似文献

Working memory and access to numerical information in children with disability in mathematics 总被引:6,自引:0,他引:6
The relationship among working memory, mathematic ability, and the cognitive impairment of children with difficulties in mathematics was examined. A group of children with difficulties in mathematics (MD) was compared with a group of children with a normal level of achievement matched for vocabulary, age, and gender (N = 49). The children were required to perform a variety of working memory and short-term memory tasks that had been administered 1 year previously. Moreover, the children were asked to perform tasks designed to provide information about speed of articulation. The results suggest a general working memory deficit in children with MD, specifically in the central executive component of Baddeley's model and primarily in the ability to inhibit irrelevant information. However, the MD children were not impaired in speech rate and counting speed tasks, which mainly involve the role of the articulatory loop. 相似文献

The association between dimensions of perfectionism and state and trait anxiety was examined in three studies. Study 1 and
Study 2 were correlational studies that investigated the link between dimensions of perfectionism (i.e., self-oriented, other-oriented,
and socially prescribed perfectionism) and the Endler Multidimensional Anxiety Scales (EMAS). Taken together, the results
indicated that self-oriented and socially prescribed perfectionsim are correlated significantly with both the cognitive-worry
and autonomic-arousal components of state anxiety. As for the trait anxiety measures, self-oriented perfectionism was associated
with the ambiguous and social evaluation facets in Study 1, and socially prescribed perfectionism was associated with the
ambiguous and daily routines facets in Study 2. The purpose of Study 3 was to examine perfectionism and state anxiety under
conditions of high versus low ego involvement. It was found that socially prescribed perfectionism was associated with higher
state anxiety, but only in the high ego involvement condition. Self-oriented perfectionism was unrelated to state anxiety
in either experimental condition. Overall, the findings indicate that socially prescribed perfectionism is the dimension linked
most closely with components of state and trait anxiety, especially under conditions of ego threat. The results are discussed
in terms of the need for an interactional approach to the study of the social aspects of both perfectionism and anxiety. 相似文献

Fuzzy intuitionistic quantum logics (called also Brouwer-Zadeh logics) represent to non standard version of quantum logic where the connective not is split into two different negation: a fuzzy-like negation that gives rise to a paraconsistent behavior and an intuitionistic-like negation. A completeness theorem for a particular form of Brouwer-Zadeh logic (BZL
3) is proved. A phisical interpretation of these logics can be constructed in the framework of the unsharp approach to quantum theory. 相似文献

A study was conducted, according to a 2 × 2 × 2 × 3 design and using the Buss aggression machine paradigm, to investigate the aggression-eliciting properties of slides of firearms. One hundred and twenty highly irritable and 120 low irritable subjects, equally divided between males and females, were given the opportunity to deliver electric shocks to an experimental confederate after having been randomly assigned to one of the six different conditions resulting from presence versus absence of previous instigation to aggress and from exposure to aggressive slides versus exposure to non-aggressive slides versus non-exposure to slides. It was found that aggressive cues, were sufficient per se to increase subsequent aggressive behaviours in observers, whether or not previously instigated to aggress. While sex differences did not seem to play any relevant role, the importance of irritability was stressed, especially where exposure to aggressive slides followed a previous instigation to aggress. 相似文献
