The purpose of this study was to examine perceptual, visual-motor abilities and intellectual skills in children with low, average and above average motor abilities. The participants were 144 children (aged 6-10 years) attending elementary school. Three groups of children were identified on the basis of their performance at the TGMD (Test of Gross Motor Development; [Ulrich, D.A. (1985). TGMD, Test of Gross Motor Development. Austin, Texas: PRO-ED. Edizione Italiana a cura di D. Ianes, TEST TGM. Test di valutazione delle abilita grosso-motorie. 1994, Trento: Edizioni Centro Studi Erickson]). Each child received an intelligence test (K-BIT; [Kaufman, A.S., & Kaufman, N.L. (1990). K-BIT. Kaufman Brief Intelligence Test. Circle Pines, MN: American Guidance Service]) and was evaluated for perceptual and visual-motor integration abilities (DTVP; [Hammill, D.D., Pearson, N.A., & Voress, J.K. (1993). Developmental Test of Visual Perception (2nd ed.). Austin, Texas: PRO-ED. Edizione Italiana a cura di D. Ianes, TEST TPV. Test di percezione visiva e integrazione visuo-motoria. Trento: Edizioni Centro Studi Erickson]). Results highlight a significant difference in visual-motor integration between children with high and low gross-motor abilities, in the absence of significant differences in perceptual skills or intellectual ability. The findings are discussed with reference to the concept of atypical brain development [Gilger, J.W., & Kaplan, B.J. (2001). Atypical brain development: A conceptual framework for understanding developmental learning disabilities. Developmental Neuropsychology, 20, 465]. 相似文献

There is an exponential speed-up in the number of lines of the quantified propositional sequent calculus over Substitution
Frege Systems, if one considers proofs as trees. Whether this is true also for the number of symbols, is still an open problem.

To understand recent anti-refugee protests in Europe, we examined how different levels of inclusiveness of group identities (national, European, and global) are related to intentions to protest among native Europeans. We focused on the mediating role of autochthony (a belief that the first inhabitants of a territory are more entitled) and the moderating role of threat. Survey data from 11 European countries (N = 1,909) showed that national identification was positively associated with autochthony, and therefore, with the intention to protest against refugees. In contrast, global identification was related to lower protest intentions via lower autochthony. These paths were found only among Europeans who perceived refugees as a threat. European identification was not related to the endorsement of autochthony or to collective action. These findings indicate why and when majority members are willing to participate in collective action against refugees, and underscore the importance of global identification in the acceptance of refugees. 相似文献

We describe a patient with right hemisphere damage affected by mild left visuo-spatial neglect and constructional apraxia. During the rehabilitation, he failed to draw a draught-board using horizontal and vertical trajectories, but he performed it successfully using oblique trajectories. These observations suggested an impairment of vertical/horizontal spatial coordinates system. In copying tasks including figure elements in different orientations he drew more accurately components in oblique orientation, whereas failed to reproduce components in horizontal orientation. The patient performed visuospatial perceptual and perceptual-imaginative tasks successfully. From these findings, it is possible to suggest that the oblique coordinate system of reference operates independently of vertical and horizontal coordinate systems in building a complex figure and that, therefore, cardinal orientation do not constitute a reference norm to define oblique orientation, as previously suggested. 相似文献

The issue of handedness has been the topic of great interest for researchers in a number of scientific domains. It is typically observed that the dominant hand yields numerous behavioral advantages over the non-dominant hand during unimanual tasks, which provides evidence of hemispheric specialization. In contrast to advantages for the dominant hand during motor execution, recent research has demonstrated that the right hand has advantages during motor planning (regardless of handedness), indicating that motor planning is a specialized function of the left hemisphere. In the present study we explored hemispheric advantages in motor planning and execution in left- and right-handed individuals during a bimanual grasping and placing task. Replicating previous findings, both motor planning and execution was influenced by object end-orientation congruency. In addition, although motor planning (i.e., end-state comfort) was not influenced by hand or handedness, motor execution differed between left and right hand, with shorter object transport times observed for the left hand, regardless of handedness. These results demonstrate that the hemispheric advantages often observed in unimanual tasks do not extend to discrete bimanual tasks. We propose that the differences in object transport time between the two hands arise from overt shifting visual fixation between the two hands/objects. 相似文献

Background
This study analyzed the presence of awareness of movement disorders (dyskinesias and hypokinesias) in 25 patients with Parkinson’s disease (PD) and motor fluctuations (dyskinesias, wearing off, on–off fluctuations). Of the few studies that have dealt with this topic, none have analyzed the differences in the awareness of motor deficits by comparing the on and off states using motor scales and an extensive battery of tests to assess cognitive and behavioral functioning.Methods
PD patients were compared on three different scales that we have devised to measure awareness of movement disorders: Global Awareness of Movement (GAM) Disorders, dyskinesia/hypo-bradykinesia rating scales.Results
Data showed that PD patients had greater awareness and psychological suffering in the off state than in the on state. In particular, they were troubled by motor disabilities related to hypokinesias and had mood-related symptoms and a perception of disability in activities of daily living. Interestingly, patients only showed a selective reduction of awareness of movement disorders associated with executive functions and related to dyskinesias in the on state, compared to a preserved awareness of hypokinesias in the off state. On the contrary, no association with executive functions was found in the off state.Conclusion
Our findings suggest that the dopaminergic overstimulation of mesocorticolimbic pathways may cause a dysfunction of prefrontal–subcortical connections related to the impaired insight. 相似文献47.
Verb bias, or the tendency of a verb to appear with a certain type of complement, has been employed in psycholinguistic literature
as a tool to test competing models of sentence processing. To date, the vast majority of sentence processing research involving
verb bias has been conducted almost exclusively with monolingual speakers, and predominantly with monolingual English speakers,
despite the fact that most of the world’s population is bilingual. To test the generality of competing theories of sentence
comprehension, it is important to conduct cross-linguistic studies of sentence processing and to add bilingual data to theories
of sentence comprehension. Given this, it is critical for the field to develop verb bias estimates from monolingual speakers
of languages other than English and from bilingual populations. We begin to address these issues in two norming studies. Study
1 provides verb bias norming data for 135 Spanish verbs. A second aim of Study 1 was to determine whether verb bias estimates
remain stable over time. In Study 2, we asked whether Spanish—English speakers are able to learn verb-specific information,
such as verb bias, in their second language. The answer to this question is critical to conducting studies that examine when,
during the course of sentence comprehension, bilingual speakers exploit verb information specific to the second language.
To facilitate cross-linguistic work, we compared our verb bias results with those provided by monolingual English speakers
in a previous norming study conducted by Garnsey, Lotocky, Pearlmutter, and Myers (1997). Our Spanish data demonstrated that
individual verbs showed significant similarities in their verb bias across the 3 years of data collection. We also show that
bilinguals are able to learn the biases of verbs in their second language, even when immersed in the first language environment.

This study investigates mother–child interaction and its associations with play in children with Down syndrome (DS). There is consensus that mother–child interaction during play represents an important determinant of typical children's play development. Concerning children with DS, few studies have investigated mother–child interaction in terms of the overall emotional quality of dyadic interaction and its effect on child play. A sample of 28 children with DS (M age = 3 years) took part in this study. In particular, we studied whether the presence of the mother in an interactional context affects the exploratory and symbolic play of children with DS and the interrelation between children's level of play and dyadic emotional availability. Children showed significantly more exploratory play during collaborative play with mothers than during solitary play. However, the maternal effect on child symbolic play was higher in children of highly sensitive mothers relative to children whose mothers showed lower sensitivity, the former displaying more symbolic play than the latter in collaborative play. Results offer some evidence that dyadic emotional availability and child play level are associated in children with DS, consistent with the hypothesis that dyadic interactions based on a healthy level of emotional involvement may lead to enhanced cognitive functioning. 相似文献

In the present study we considered the two factors that have been advocated for playing a role in emotional attention: perception
of gaze direction and facial expression of emotions. Participants performed an oculomotor task in which they had to make a
saccade towards one of the two lateral targets, depending on the colour of the fixation dot which appeared at the centre of
the computer screen. At different time intervals (stimulus onset asynchronies, SOAs: 50,100,150 ms) following the onset of
the dot, a picture of a human face (gazing either to the right or to the left) was presented at the centre of the screen.
The gaze direction of the face could be congruent or incongruent with respect to the location of the target, and the expression
could be neutral or angry. In Experiment 1 the facial expressions were presented randomly in a single block, whereas in Experiment
2 they were shown in separate blocks. Latencies for correct saccades and percentage of errors (saccade direction errors) were
considered in the analyses. Results showed that incongruent trials determined a significantly higher percentage of saccade
direction errors with respect to congruent trials, thus confirming that gaze direction, even when task-irrelevant, interferes
with the accuracy of the observer’s oculomotor behaviour. The angry expression was found to hold attention for a longer time
with respect to the neutral one, producing delayed saccade latencies. This was particularly evident at 100 ms SOA and for
incongruent trials. Emotional faces may then exert a modulatory effect on overt attention mechanisms. 相似文献

Several past studies have considered how perceived head orientation may be combined with perceived gaze direction in judging where someone else is attending. In three experiments we tested the impact of different sources of information by examining the role of head orientation in gaze-direction judgements when presenting: (a) the whole face; (b) the face with the nose masked; (c) just the eye region, removing all other head-orientation cues apart from some visible part of the nose; or (d) just the eyes, with all parts of the nose masked and no head orientation cues present other than those within the eyes themselves. We also varied time pressure on gaze direction judgements. The results showed that gaze judgements were not solely driven by the eye region. Gaze perception can also be affected by parts of the head and face, but in a manner that depends on the time constraints for gaze direction judgements. While “positive” congruency effects were found with time pressure (i.e., faster left/right judgements of seen gaze when the seen head deviated towards the same side as that gaze), the opposite applied without time pressure. 相似文献
