Ongoing debate in the literature concerns whether there is a link between contagious yawning and the human mirror neuron system
(hMNS). One way of examining this issue is with the use of the electroencephalogram (EEG) to measure changes in mu activation
during the observation of yawns. Mu oscillations are seen in the alpha bandwidth of the EEG (8–12 Hz) over sensorimotor areas.
Previous work has shown that mu suppression is a useful index of hMNS activation and is sensitive to individual differences
in empathy. In two experiments, we presented participants with videos of either people yawning or control stimuli. We found
greater mu suppression for yawns than for controls over right motor and premotor areas, particularly for those scoring higher
on traits of empathy. In a third experiment, auditory recordings of yawns were compared against electronically scrambled versions
of the same yawns. We observed greater mu suppression for yawns than for the controls over right lateral premotor areas. Again,
these findings were driven by those scoring highly on empathy. The results from these experiments support the notion that
the hMNS is involved in contagious yawning, emphasise the link between contagious yawning and empathy, and stress the importance
of good control stimuli. 相似文献

The base units of the SI include six units of continuous quantities and the mole, which is defined as proportional to the number of specified elementary entities in a sample. The existence of the mole as a unit has prompted comment in Metrologia that units of all enumerable entities should be defined though not listed as base units. In a similar vein, the BIPM defines numbers of entities as quantities of dimension one, although without admitting these entities as base units. However, there is a basic ontological distinction between continuous quantities and enumerable aggregates. The distinction is the basis of the difference between real and natural numbers. This paper clarifies the nature of the distinction: (i) in terms of a set of measurement axioms stated by H?lder; and (ii) using the formalism known in metrology as quantity calculus. We argue that a clear and unambiguous scientific distinction should be made between measurement and enumeration. We examine confusion in metrological definitions and nomenclature concerning this distinction, and discuss the implications of this distinction for ontology and epistemology in all scientific disciplines. 相似文献

From the perspective of terror management theory, awareness of death induces a need for validation of important values. Thus, for women who place a high value on their appearance (e.g., high self-objectifiers), mortality salience should increase positive reactions to objectifying experiences relative to women who do not highly value appearance. Two studies supported this hypothesis. Self-objectification moderated favorable reactions to objectifying stimuli (Study 1) and state self-esteem in response to an objectifying comment (Study 2) when women were primed with death. Together, the studies illustrate the complexity of reactions to objectification and, by highlighting conditions in which objectification serves a psychological function, help to explain the pervasiveness of the phenomena. 相似文献

We agree with the commentaries that Relational psychoanalysis has stood firmly against dichotomizing clinical reflection, on one hand, and interactional processes, on the other. Still, we wonder whether the relational literature has skewed toward interaction at the expense of concentrated attention to patients’ internal worlds. Predispositions toward interaction may diminish reflective space and quiet inwardness, which are themselves forms of analytic relating. We raise the possibility that the Relational model’s inclusive breadth, valuable as it is, might sometimes impede and even devalue discussions of specific technical matters. We consider clinical conceptualizations of ritual, “relating,” and “being in contact.” 相似文献

Theory and treatment for childhood anxiety disorders typically implicates children’s negative cognitions, yet little is known about the characteristics of thinking styles of clinically anxious children. In particular, it is unclear whether differences in thinking styles between children with anxiety disorders and non-anxious children vary as a function of child age, whether particular cognitive distortions are associated with childhood anxiety disorders at different child ages, and whether cognitive content is disorder-specific. The current study addressed these questions among 120 7–12 year old children (53% female) who met diagnostic criteria for social anxiety disorder, other anxiety disorder, or who were not currently anxious. Contrary to expectations, threat interpretation was not inflated amongst anxious compared to non-anxious children at any age, although older (10–12 year old) anxious children did differ from non-anxious children on measures of perceived coping. The notion of cognitive-content specificity was not supported across the age-range. The findings challenge current treatment models of childhood anxiety, and suggest that a focus on changing anxious children’s cognitions is not warranted in mid-childhood, and in late childhood cognitive approaches may be better focussed on promoting children’s perceptions of control rather than challenging threat interpretations. 相似文献

Human control of action in routine situations involves a flexible interplay between (a) task‐dependent serial ordering constraints; (b) top‐down, or intentional, control processes; and (c) bottom‐up, or environmentally triggered, affordances. In addition, the interaction between these influences is modulated by learning mechanisms that, over time, appear to reduce the need for top‐down control processes while still allowing those processes to intervene at any point if necessary or if desired. We present a model of the acquisition and control of goal‐directed action that goes beyond existing models by operationalizing an interface between two putative systems—a routine and a non‐routine system—thereby demonstrating how explicitly represented goals can interact with the emergent task representations that develop through learning in the routine system. The gradual emergence of task representations offers an explanation for the transfer of control with experience from the non‐routine goal‐based system to the routine system. At the same time it allows action selection to be sensitive both to environmental triggers and to biasing from multiple levels within the goal system. 相似文献
