People differ with regard to how they perceive, experience, and express negative affect. While trait negative affect reflects a stable, sustained personality trait, state negative affect represents a stimulus limited and temporally acute emotion. So far, little is known about the neural systems mediating the relationship between negative affect and acute emotion processing. To address this issue we investigated in a healthy female sample how individual differences in state negative affect are reflected in changes in blood oxygen level-dependent responses during passive viewing of emotional stimuli. To assess autonomic arousal we simultaneously recorded changes in skin conductance level. At the psychophysiological level we found increased skin conductance level in response to aversive relative to neutral pictures. However, there was no association of state negative affect with skin conductance level. At the neural level we found that high state negative affect was associated with increased left insular activity during passive viewing of aversive stimuli. The insula has been implicated in interoceptive processes and in the integration of sensory, visceral, and affective information thus contributing to subjective emotional experience. Greater recruitment of the insula in response to aversive relative to neutral stimuli in subjects with high state negative affect may represent increased processing of salient aversive stimuli. 相似文献

This paper is concerned with reasonings that purport to explain why certain organisms have certain traits by showing that
their actual design is better than contrasting designs. Biologists call such reasonings ‘functional explanations’. To avoid
confusion with other uses of that phrase, I call them ‘design explanations’. This paper discusses the structure of design
explanations and how they contribute to scientific understanding. Design explanations are contrastive and often compare real
organisms to hypothetical organisms that cannot possibly exist. They are not causal but appeal to functional dependencies
between an organism’s different traits. These explanations point out that because an organism has certain traits (e.g., it
lives on land), it cannot be alive if the trait to be explained (e.g., having lungs) were replaced by a specified alternative
(e.g., having gills). They can be understood from a mechanistic point of view as revealing the constraints on what mechanisms
can be alive.

Engelmann believes in two general strong beliefs. On one side, Engelmann believes in probabilistic skepticism. That the existence
has its maximum probability or there is no existence at all is not possible. The other probabilities of existence are always
possible. On the other hand, instead of elements that constitute a beginning arrived at by an unknown division, the Gestalt
theory begins with wholes or Gestalten. These Gestalten can be divided in parts but each part can be only a part of his specific
Gestalt. The majority of probabilistic skeptics and the majority of Gestalt theory followers do not believe they can be together
accepted. On the contrary Engelmann is a member of a small group that both beliefs occur simultaneously. Bibace’s questions
were each answered by Engelmann. In some questions Engelmann harmonize with Bibace, in others they disagree.

Starting pre-school is a major stepping stone for children’s peer relations. Yet, some children spend their recess time alone, albeit in the presence of playful peers. These solitary behaviours have been noted in the literature as an alarm signal for a maladaptive social development. In this study, we identified four kinds of non-social behaviours engaged at recess (reticent, solitary-pretend, -functional, and -passive); and we examined the extent to which these different behaviours were related to social solitude at the playground six months later. Therefore, 97 children (aged 4–6 years old) were observed at the playground and their social-emotional skills were tested. Solitude was assessed through an innovative measuring method, based on Radio Frequency Identification Devices. The results demonstrated that solitary-pretend play in girls was related to an increase in solitary behaviours later on. Nevertheless, children who engaged in non-social behaviours showed a general lack of emotional skills, which may explain their initial withdrawal. 相似文献

In two matching tasks, participants had to match two images of object pairs. Image-based (IB) connectedness refers to connectedness between the objects in an image. Object-based (OB) connectedness refers to connectedness between the interpreted objects. In Experiment 1, a monocular depth cue (shadow) was used to distinguish different relation types between object pairs. Three relation types were created: IB/OB-connected objects, IB/OB-disconnected objects, and IB-connected/OB-disconnected objects. It was found that IB/OB-connected objects were matched faster than IB/OB-disconnected objects. Objects that were IB-connected/OB-disconnected were matched equally to IB/OB-disconnected objects. In Experiment 2, stereoscopic presentation was used. With relation types comparable to those in Experiment 1, it was again found that OB connectedness determined speed of matching, rather than IB connectedness. We conclude that matching of projections of three-dimensional objects depends more on OB connectedness than on IB connectedness. 相似文献

The presupposed advantage of symmetrical objects over asymmetrical objects was investigated in an object matching task, using accidental and non-accidental viewpoints. In addition, the accidental views could be symmetric or asymmetric. When two non-accidental views were presented, symmetrical objects were matched faster than asymmetrical objects. When an accidental view was presented first (followed by a non-accidental view), the matching of symmetrical objects was equal to that of asymmetrical objects. When a non-accidental view was presented first (followed by an accidental view), matching was again equal for the symmetrical and asymmetrical objects, although much faster compared with the opposite sequence of presented views. No effects of image symmetry in the accidental viewpoints were found. Apparently, the advantage of symmetrical objects over asymmetrical objects is only present in object matching when 3-D object structures are visible. 相似文献

A “Hope Box” is a therapeutic tool employed by clinicians with patients who are having difficulty coping with negative thoughts and stress, including patients who may be at risk of suicide or nonsuicidal self‐harm. We conducted a proof‐of‐concept test of a “Virtual” Hope Box (VHB)—a smartphone app that delivers patient‐tailored coping tools. Compared with a conventional hope box integrated into VA behavioral health treatment, high‐risk patients and their clinicians used the VHB more regularly and found the VHB beneficial, useful, easy to set up, and said they were likely to use the VHB in the future and recommend the VHB to peers. 相似文献
