the purpose of the present study was to investigate the effect of task-based instruction of vocabulary on the receptive and oral productive acquisition of english vocabulary and compare the results with those obtained from the traditional method. the method and procedure applied in this study was as follows: after the implementation of opt, a group of sixty female students were chosen. the stu...
Growth and development of maxillofacial morphology and oral function are closely interrelated. Oral function is comprised of articulation, swallowing, and chewing. Malocclusion may be caused by abnormal functions such as mouth breathing, tongue thrust swallowing, and unilateral chewing and by abnormal postures of oral circumferential muscles such as forward tongue thrust, tongue biting, and low...
BACKGROUND The reduced ability to identify a second target when it is presented in close temporal succession of a first target is called the attentional blink (AB). Studies have shown large individual differences in AB task performance, where lower task performance has been associated with more reversed order reports of both targets if these were presented in direct succession. In order to stud...
Neurological, auditory, vestibular and ocular motor examinations were performed on 3 definite and 3 possible heterozygous carriers of a previously described X-linked multi-system disorder with early childhood onset, rapid progression and a fatal outcome (Arts et al., 1993). The symptoms, i.e., delayed motor development, ataxia, hearing loss and subnormal intelligence, were so evident in 2 of th...
CASE DESCRIPTION A 2-year-old spayed female domestic shorthair cat was examined because of bilateral thoracic limb weakness of acute onset. CLINICAL FINDINGS Clinical signs included muscle atrophy, paresis, depressed spinal reflexes, hyperesthesia of the thoracic limbs, and reduced jaw muscle tone. Pelvic limb reflexes were normal. Results of a neurologic examination were suggestive of multif...
When two visual targets are presented in a rapid serial visual presentation (RSVP) paradigm, the ability to identify the second target is reduced when it is presented 200-500ms after the initial target. This phenomenon is referred to as the "attentional blink (AB)." Previous behavioral studies have reported aberrant AB in schizophrenia. The underlying cause, however, of the AB deficit in schizo...
Studies have suggested attention-free semantic processing of natural scenes in which concurrent tasks leave category detection unimpaired (e.g., F. Li, R. VanRullen, C. Koch, & P. Perona, 2002). Could this ability reflect detection of disjunctive feature sets rather than high-level binding? Participants detected an animal target in a rapid serial visual presentation (RSVP) sequence and then rep...
This study examined the extent to which early adolescents (aged 10-13 years) differ from adults in their sensitivity to attention capture by affective stimuli during rapid processing. A rapid serial visual presentation paradigm (RSVP) was implemented as a dual task, requiring the report of two green target stimuli embedded in a stream of distractors. Known as the "attentional blink" (AB), task ...
When the second of two targets is presented temporally close (within 500 ms) to the first target in rapid serial visual presentation, accuracy for reporting the second target is markedly diminished-an attentional blink (AB). The AB has become a well-studied phenomenon, and multiple different versions of the AB are currently in use. However, little is known about the stability of individual perf...
Identification of a second target is often impaired by the requirement to process a prior target in a rapid serial visual presentation (RSVP). This is termed the attentional blink. Even when the first target is task irrelevant an attentional blink may occur providing this first target shares similar features with the second target (contingent capture). An RSVP experiment was undertaken to asses...
