What's the difference between trigram and trigraph?
Trigram
Definition:
(n.) Same as Trigraph.
Example Sentences:
(1) A within-subjects design was used in which trained subjects were told on a given trial either to produce alpha rhythm, mentally rehearse, or count backward following presentation of a CCC trigram.
(2) In Experiment 1, partial identity priming using word-final trigrams was observed only when the bigram corresponded to the orthographic rime unit.
(3) Memory trigrams were presented by one of three methods: visual-concurrent (all three letters appeared simultaneously), visual-successive, and auditory-successive.
(4) The tests consisted of word lists, picture tests, and syllable pairs (consonant-vowel-consonant trigrams).
(5) Subjects learned lists of consonant trigram word pairs varying in intralist formal stimulus similarity.
(6) The subcortical equivalent and changes of the reproducible pattern in response to meaningless trigrams and words were only observed within the weak signal range.
(7) Four viewing conditions were used, each affording full view of the directly fixated word: no preview of the spatially adjacent parafoveal word; preview of its beginning trigram; preview of its beginning four letters; or preview of all its constituent letters.
(8) Reading afforded either no parafoveal preview, preview of beginning trigrams, preview of ending trigrams, or preview of the whole parafoveal word.
(9) Depending on the required serial order of readout of the trigram perceptual impairment was more marked for the second and third part of the trigram.
(10) 56 male and 56 female familial right-handers were given a tachistoscopic task requiring recognition of trigrams presented binocularly and vertically in the right or left visual field for individuality determined brief durations.
(11) In the present study six subjects were visually presented 15 CVC trigrams while their pupil sizes were monitored.
(12) To test these hypotheses, eight patients with unilateral neglect were given consonant trigrams randomly to either ear, and the patients were asked to identify the auditory stimuli either immediately or after an 18 second delay during which time the patients were asked to count.
(13) The identification of trigrams, presented for 14 ms in horizontal or vertical arrays was significantly impaired when the visual stimulus preceded the occipital magnetic shock by 40 to 120 ms.
(14) Obese and normal-weight subjects were run on a series of recognition-memory tasks with low and high meaningful CVC trigrams.
(15) The effects of magnetic coil (MC) stimulation of human visual cortex on the foveal perception of briefly presented letter trigrams include: (1) letters were nearly always reported correctly at visual stimulus-MC pulse intervals less than 60-80 msec or greater than 120-140 msec.
(16) Subjects in the semantic elaboration group were instructed to generate sentences to link the trigram and word in a memorable way.
(17) Highly meaningful trigrams had a significantly lower response criterion than low meaningful trigrams and there was a significant interaction of meaningfulness by trials.
(18) Twelve trigrams divided into four sets, the members of each set varying systematically in the feature configuration at each letter position, were repeatedly exposed at brief durations in a random order to subjects who were asked to report after each exposure those letters that could be recognized with certainty.
(19) Her memory was examined prior to as well as following each series of plasma exchanges with a variation of the Peterson-Peterson consonant trigram task.
(20) The set of three trigrams that had the same features for all letters in a given ordinal position was identified with fewer exposures than were necessary to permit identification of sets for which the featural characteristics varied within a spatial position.
Trigraph
Definition:
(n.) Three letters united in pronunciation so as to have but one sound, or to form but one syllable, as -ieu in adieu; a triphthong.
