It was found [Vision Res. 36 (1996) 2125] that reaction times for repeated targets were longer in detection and location discrimination tasks (inhibition of return; IOR) and shorter in color and orientation discrimination tasks (facilitation of return; FOR). The present experiment, using a more detailed analysis, shows that both IOR and FOR can be found in the discrimination tasks. Overall, the...

one of the methods to recognize national background and roots, also to maintain historical and cultural nature is to study different dimensions of physical, martial and athletic activities in ancient iran. the aim of the present study was to identify different sport fields and equipment in ancient iran using content analysis of nine versions of ferdowsi’s “shahnameh” and related literature. als...

Simultaneous self-induced transparency and a dark line resonance are observed inside a mode-locked laser. The circulating pulse, tuned to the 795-nm optical resonance of rubidium, has sufficient intensity to create at each passage a population inversion-return to ground state, typical of self-induced transparency. A drop in fluorescence (dark line resonance), is observed as the repetition rate ...

There is an extensive literature on the phenomenon of inhibition of return (IOR): When attention is drawn to a peripheral location and then removed, response time is delayed if a target appears in the previously inspected location. Recent research suggests that non-spatial attribute repetition (i.e., if a target shares a feature like color with the earlier, cueing, stimulus) can have a similar ...

We report an all-fiber pulsed source based on parametric conversion followed by thulium amplification able to deliver picosecond pulses at a repetition rate selectable between 2 and 5 GHz, of which central wavelength can be freely selected in the 2-μm region. A very versatile Nyquist pulse shaping of the parametric pump, which allows for the electrical control of the pulse train, enables such a...

repetition is one technique in language of poetry through which a word or phrase has various technical implications that impress the reader. the skillful poet, who can direct the word to be worthwhile and sensuous, is able to do that work.the value of this kind of repetition rises due to its implications where the poet owns verbal and emotional originality. if there is any defect in his talent,...

The speech rate is one of the important prosodic parameters for the naturalness and intelligibility of an utterance. On the basis of the authors’ definition of the relative local speech rate, the present paper describes an analysis of the effects of changes in global speech rate, syntactic constituency and lexical accent on the local speech rate, using short utterances in which these factors ar...

Hesitations are prevalent in spontaneous speech and believed to be relevant to on-line speech planning. We tested the complexity hypothesis that speakers are more likely to need to suspend speaking, the more complex the constituent, by examining ratios of filled pauses (fillers) at clause and case boundaries with following constituents of different degrees of complexity, using ì the Corpus of s...

Three forced-choice perceptual word identification experiments tested the claim that transitions from positive to negative priming as a function of increasing prime duration are due to cognitive aftereffects. These aftereffects are similar in nature to perceptual aftereffects that produce a negative image due to overexposure and habituation to a stimulus. Each experiment tested critical predict...
