introduction: stereotypy is one of the main features of children with autism. these behaviors are associated with deficit in learning processes, social skills acquisition, increased family stress, and self-injuries behaviors. the purpose of the present study was aimed to investigate the effectiveness of two selected karate-hand techniques on hand stereotypic movements in a boy with autism. mate...

opposite limbs are made in antiphase, with identical frequency of all four limbs. These kinematical characteristics generated the hypothesis that, in humans, the cerebral control of this stereotypic movement pattern is associated with a common circuitry involved in antiphase movement, independent from execution by either the two upper or the two lower limbs. By means of positron emission tomogr...

Humans and animals trained on sequential reaction tasks show decreases in reaction time and increases in anticipatory movements even long after they have ceased to make errors. Humans show these changes even when they do not explicitly recognize that they performed a repeating sequence. We have developed a task which rats learn to perform error-free quickly, but in which they continue to show p...

Three studies demonstrate that stereotypic movements activate the corresponding stereotype. In Study 1, participants who were unobtrusively induced to move in the portly manner that is stereotypic of overweight people subsequently ascribed more overweight-stereotypic characteristics to an ambiguous target person than did control participants. In Study 2, participants who were unobtrusively indu...

In this study, we took advantage of the reported role of EphA4 in determining the contralateral spinal projection of the corticospinal tract (CST) to investigate the effects of ipsilateral misprojections on voluntary movements and stereotypic locomotion. Null EphA4 mutations produce robust ipsilateral CST misprojections, resulting in bilateral corticospinal tracts. We hypothesize that a unilate...

Autistic disorder, an extremely disabling syndrome with onset in early childhood, is associated with multiple comorbid conditions. Although autistic disorder is heterogeneous in its manifestations, there is a subgroup of individuals with autistic disorder who display movements that appear to be unique for the disorders. Hand flapping and a variety of movements termed stereotypies may be pathogn...

OBJECTIVES Previous studies showed that negative self-stereotypes detrimentally affect the cognitive performance of marginalized group members; however, these findings were confined to short-term experiments. In the present study, we considered whether stereotypes predicted memory over time, which had not been previously examined. We also considered whether self-relevance increased the influenc...

The effects of noncontingent matched stimulation (NMS) and response blocking on a boy's stereotypic behavior were evaluated using a multiple schedule that contained three 15-min components (preintervention, intervention, and postintervention). Results showed that stereotypy was always higher after response blocking than before response blocking and was always lower after NMS than before NMS. Th...

This paper develops a semantic analysis of the three constructions: (i) the subjectoriented adverb construction (Wisely, John left early), (ii) the ‘Adj. + to Inf.’ construction (John was wise to leave early), and (iii) the ‘Adj. + of NP’ construction (It was wise of John to leave early), which all involve three semantic components: (i) an individual a (John), (ii) a property P1 that describes ...
