The objective was to validate Regulatory Sensory Processing Disorders’ criteria (DC:0-3R, 2005) using empirical data on the presence and severity of sensory modulation deficits and specific psychiatric symptoms in clinical samples. Sixty toddlers who attended a child mental health unit were diagnosed by a clinical team. The following two groups were created: toddlers with RSPD (N?=?14) and those with “other diagnoses in Axis I/II of the DC:0-3R″(OD3R) (N?=?46). Independently of the clinical process, parents completed the Infant Toddler Sensory Profile (as a checklist for sensory symptoms) and the Achenbach Behavior Checklist for ages 1?–5 (CBCL 1?–5). The scores from the two groups were compared. The results showed the following for the RSPD group: a higher number of affected sensory areas and patterns than in the OD3R group; a higher percentage of sensory deficits in specific sensory categories; and a higher severity of behavioral symptoms such as withdrawal, inattention, other externalizing problems and pervasive developmental problems in CBCL 1?–5. The results confirmed our hypotheses by indicating a higher severity of sensory symptoms and identifying specific behavioral problems in children with RSPD. The results revealed convergent validity between the instruments and the diagnostic criteria for RSPD and supported the validity of RSPD as a unique diagnosis. The findings also suggested the importance of identifying sensory modulation deficits in order to develop an early intervention to enhance the sensory capacities of children who do not fully satisfy the criteria for some DSM-IV-TR disorders. 相似文献

The factor structure, internal consistency, construct validity, and predictive validity of the Dutch version of the Five Facet Mindfulness Questionnaire (FFMQ-NL) were studied in a sample of meditators (n = 288) and nonmeditators (n = 451). A five-factor structure was demonstrated in both samples, and the FFMQ-NL and its subscales were shown to have good internal consistencies. Meditators scored higher on all facets of the FFMQ-NL than the participants in the nonmeditating sample. For both samples, expected negative correlations between most mindfulness facets (all except for the Observing facet) and the constructs of alexithymia, thought suppression, rumination, worry, and dissociation were found. The Observing facet of the FFMQ-NL showed an unexpected positive correlation with thought suppression in the nonmeditating sample. Furthermore, as expected, mindfulness facets were negatively related to psychological symptoms, and all mindfulness facets except for Observing and Describing significantly predicted psychological symptoms. Overall, the Dutch FFMQ demonstrated favorable psychometric properties, commensurate with its (original) English language version. 相似文献

Prominent models of attentional control assert a dichotomy between top-down and bottom-up control, with the former determined by current selection goals and the latter determined by physical salience. This theoretical dichotomy, however, fails to explain a growing number of cases in which neither current goals nor physical salience can account for strong selection biases. For example, equally salient stimuli associated with reward can capture attention, even when this contradicts current selection goals. Thus, although 'top-down' sources of bias are sometimes defined as those that are not due to physical salience, this conception conflates distinct--and sometimes contradictory--sources of selection bias. We describe an alternative framework, in which past selection history is integrated with current goals and physical salience to shape an integrated priority map. 相似文献

Envy is the unpleasant emotion that can arise when people are exposed to others with superior possessions. Common wisdom and scholarly opinion suggest that when people experience envy they may be motivated to obtain the others' superior possession. Despite the vast interpersonal, societal, and economical consequences attributed to this potential aspect of envious responding, experimental demonstrations of the affective and behavioral consequences of envy-inducing situations are scarce. We propose that social comparisons with better-off others trigger an impulsive envious response that entails a behavioral tendency to strive for their superior good. However, given that the experience of envy is painful, self-threatening, and met with social disapproval, people typically attempt to control their envious reactions. Doing so requires self-control capacities, so that envious reactions may only become apparent if self-control is taxed. In line with these predictions, four experiments show that only when self-control resources are taxed, upward comparisons elicit envy paired with an increased willingness to pay for, to spontaneously purchase and to impulsively approach the superior good. 相似文献

Holding an intention often interferes with other ongoing activities, indicating that resource-demanding processes are involved
in maintaining the intention and noticing the appropriate event to fulfill it. Little is known, however, about the nature
of the processes underlying this task interference effect. The goal of the present research was to decompose the processes
contributing to the task interference effect by applying the diffusion model (Ratcliff, Psychological Review 85:59–108, 1978) to an event-based prospective memory task. In the first experiment, we validated the interpretation of the response criterion
parameter (a) of the diffusion model as reflecting strategies to cope with the anticipated demands of a prospective memory task in the
context of the ongoing task. The second experiment served to investigate which underlying processes contribute to the task
interference often found with prospective memory tasks. Diffusion model analyses revealed that the task interference effect
was due to (1) less efficient processing in the more demanding than in the less demanding prospective memory task and (2)
a more conservative response criterion. We suggest that the anticipated demands and the additional processing demands of the
prospective memory task jointly contribute to the task interference effect. 相似文献

There is an ongoing controversy regarding the relationship between covert attention and saccadic eye movements. While there is quite some evidence that the preparation of a saccade is obligatory preceded by a shift of covert attention, the reverse is not clear: Is allocation of attention always accompanied by saccade preparation? Recently, a shifting and maintenance account was proposed suggesting that shifting and maintenance components of covert attention differ in their relation to the oculomotor system. Specifically, it was argued that a shift of covert attention is always accompanied by activation of the oculomotor program, while maintaining covert attention at a location can be accompanied either by activation or suppression of oculomotor program, depending on the probability of executing an eye movement to the attended location. In the present study we tested whether there is such an obligatory coupling between shifting of attention and saccade preparation and how quickly saccade preparation gets suppressed. The results showed that attention shifting was always accompanied by saccade preparation whenever covert attention had to be shifted during visual search, as well as in response to exogenous or endogenous cues. However, for the endogenous cues the saccade program to the attended location was suppressed very soon after the attention shift was completed. The current findings support the shifting and maintenance account and indicate that the premotor theory needs to be updated to include a shifting and maintenance component for the cases in which covert shifts of attention are made without the intention to execute a saccade.

Abstract : In this article I argue that the Lutheran doctrine of two kingdoms provides a good basis for the legitimate participation of all citizens in political discourse and decisions, no matter what faith they hold. The argument is backed by selected insights from philosopher Jürgen Habermas and sociologists Linda Woodhead and Paul Heelas. Against this backdrop, I suggest some challenges for a theology that addresses issues related to religion and society. 相似文献

Over the past two decades, research has accumulated compelling evidence that sleep supports the formation of long-term memory.
The standard two-stage memory model that has been originally elaborated for declarative memory assumes that new memories are
transiently encoded into a temporary store (represented by the hippocampus in the declarative memory system) before they are
gradually transferred into a long-term store (mainly represented by the neocortex), or are forgotten. Based on this model,
we propose that sleep, as an offline mode of brain processing, serves the ‘active system consolidation’ of memory, i.e. the
process in which newly encoded memory representations become redistributed to other neuron networks serving as long-term store.
System consolidation takes place during slow-wave sleep (SWS) rather than rapid eye movement (REM) sleep. The concept of active
system consolidation during sleep implicates that (a) memories are reactivated during sleep to be consolidated, (b) the consolidation
process during sleep is selective inasmuch as it does not enhance every memory, and (c) memories, when transferred to the
long-term store undergo qualitative changes. Experimental evidence for these three central implications is provided: It has
been shown that reactivation of memories during SWS plays a causal role for consolidation, that sleep and specifically SWS
consolidates preferentially memories with relevance for future plans, and that sleep produces qualitative changes in memory
representations such that the extraction of explicit and conscious knowledge from implicitly learned materials is facilitated. 相似文献

A series of four experiments investigating gaze behavior and decision making in the context of wayfinding is reported. Participants were presented with screenshots of choice points taken in large virtual environments. Each screenshot depicted alternative path options. In Experiment 1, participants had to decide between them to find an object hidden in the environment. In Experiment 2, participants were first informed about which path option to take as if following a guided route. Subsequently, they were presented with the same images in random order and had to indicate which path option they chose during initial exposure. In Experiment 1, we demonstrate (1) that participants have a tendency to choose the path option that featured the longer line of sight, and (2) a robust gaze bias towards the eventually chosen path option. In Experiment 2, systematic differences in gaze behavior towards the alternative path options between encoding and decoding were observed. Based on data from Experiments 1 and 2 and two control experiments ensuring that fixation patterns were specific to the spatial tasks, we develop a tentative model of gaze behavior during wayfinding decision making suggesting that particular attention was paid to image areas depicting changes in the local geometry of the environments such as corners, openings, and occlusions. Together, the results suggest that gaze during a wayfinding tasks is directed toward, and can be predicted by, a subset of environmental features and that gaze bias effects are a general phenomenon of visual decision making. 相似文献
