Three experiments investigated word frequency and age of acquisition (AoA) effects in recognition and recall. Experiments 1 and 2 used the "remember-know" procedure developed by J. M. Gardiner (1988). In Experiment 1, recognition performance was higher for low-frequency words than for high-frequency words and higher for late-acquired words than for early-acquired words, but only in "remember" responses. Experiment 2 replicated the AoA effect by using a different set of early- and late-acquired words. Experiment 3 found advantages for low-frequency and late-acquired words in recall, but only when words were presented in mixed lists. The frequency effect was reversed, and the AoA effect was eliminated, when participants studied pure lists. Findings were attributed to the more distinctive encoding of low-frequency and late-acquired words. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Three experiments examined the word frequency effect in free recall using the overt rehearsal methodology. Experiment 1 showed that lists of exclusively high-frequency (HF) words were better recalled, were rehearsed more, and were rehearsed to more recent serial positions than low-frequency (LF) words. A small HF advantage remained even when these 2 variables were equated. Experiment 2 showed that all these effect, were much reduced with mixed lists containing both HF and LF words. Experiment 3 compared pure and mixed lists in a within-subject design and confirmed the findings of Experiments 1 and 2. It is argued that number of rehearsals, recency of rehearsals, and strength of interitem association cause the word frequency effect in free recall.

This study examined whether spatial location mediates intentional forgetting of peripherally presented words. Using an item-method directed forgetting paradigm, words were presented in peripheral locations at study. A recognition test presented all words at either the same or a different location relative to study. Results showed that while recognition of Remember words was unaffected by test location, when Forget words were presented in the same location at test as at study, recognition accuracy was significantly greater than when presented in a different location. Experiment 2 showed that the speed to localize a previously studied word was faster when it was presented in the same rather than a different study-test location but that the magnitude of this spatial priming was unaffected by memory instruction. We suggest that the location of peripherally presented words is represented in memory and can aid the retrieval of poorly encoded words.

The order-encoding hypothesis (E. L. DeLosh & M. A. McDaniel, 1996) assumes that serial-order information contributes to the retrieval of list items and that serial-order encoding is better for common items than bizarre items. In line with this account, Experiment 1 revealed better free recall and serial-order memory for common than for bizarre items in pure lists, and Experiment 2 showed that recall for bizarre items increased and the recall advantage of common items was eliminated when serial-order encoding for bizarre items was increased to the level of common items. However, inconsistent with a second assumption that bizarre-item advantages in mixed lists reflect better individual-item encoding for bizarre items, Experiments 3 and 4 showed that the bizarreness effect in mixed lists is eliminated when alternative retrieval strategies are encouraged. This set of findings is better explained by the differential-retrieval-process framework, which proposes that contextual factors (e.g., list composition) influence the extent to which various types of information are used at retrieval, with the bizarreness advantage in mixed lists dependent on a distinctiveness-based retrieval process.

In two experiments, we investigated the interpretation and boundary conditions of the tongue-twister (TT) effect in silent reading. Previously, McCutchen, Bell, France, and Perfetti (1991) observed a TT effect when students made semantic acceptability judgments on sentences, but not when they made lexical decisions on lists of words. Using similar methodology in Experiment 1, along with two changes (using "better" TTs and longer word lists), we observed a TT effect in a lexical decision task. In Experiment 2, a memory span task revealed that students recalled fewer words from TT lists than from control lists. These results suggest that the basic mechanism of the TT effect may be articulatory, rather than working-memory, interference that occurs during lexical access and resurfaces post-lexically, inhibiting efforts to maintain the temporal order of several words. 相似文献

The word length effect, the finding that lists of short words are better recalled than lists of long words, has been termed one of the benchmark findings that any theory of immediate memory must account for. Indeed, the effect led directly to the development of working memory and the phonological loop, and it is viewed as the best remaining evidence for time-based decay. However, previous studies investigating this effect have confounded length with orthographic neighborhood size. In the present study, Experiments 1A and 1B revealed typical effects of length when short and long words were equated on all relevant dimensions previously identified in the literature except for neighborhood size. In Experiment 2, consonant–vowel–consonant (CVC) words with a large orthographic neighborhood were better recalled than were CVC words with a small orthographic neighborhood. In Experiments 3 and 4, using two different sets of stimuli, we showed that when short (1-syllable) and long (3-syllable) items were equated for neighborhood size, the word length effect disappeared. Experiment 5 replicated this with spoken recall. We suggest that the word length effect may be better explained by the differences in linguistic and lexical properties of short and long words rather than by length per se. These results add to the growing literature showing problems for theories of memory that include decay offset by rehearsal as a central feature.

Leading theoretical explanations of recency effects are designed to explain the reported absence of a word frequency effect on recall of words from recency serial positions. The present study used a directed free-recall procedure (J. I. Dalezman, 1976) and manipulated the frequency composition of the word lists (pure and mixed). Overall, with pure lists, a greater proportion of high-frequency (HF) words were recalled than low-frequency (LF) words, and with mixed lists, a greater proportion of LF words were recalled than HF words. Of importance, this recall advantage for one frequency over the other as a function of list composition was evident across the last three serial positions, indicating an influence of word frequency on recency effects that is dependent on the frequency composition of the lists. These results challenge one of the major assumptions on which several theories of recency effects have been based. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

In 3 experiments, lists of 12 Kanji words were rapidly presented in the same position, and participants reported a red target word embedded in green distractor words. Two lists were used: same and different category. A tendency toward category priming was found at longer durations. Frequency of target localization indicated that participants familiar with Kanji had a greater tendency to report the word immediately preceding the target. These pretarget intrusion errors dominated the posttarget intrusion errors, when the luminance of red and green stimuli were equated (Experiment 2), and when the response was recall (Experiments 1 and 2) or recognition (Experiment 3). In contrast, participants unfamiliar with Kanji made posttarget intrusion errors as frequently as pretarget intrusion errors (Experiment 3), suggesting that knowledge of Kanji influences the integration of color and form codes in visual information processing.

Three experiments were conducted to investigate recall of lists of words containing items spoken by either a single talker or by different talkers. In each experiment, recall of early list items was better for lists spoken by a single talker than for lists of the same words spoken by different talkers. The use of a memory preload procedure demonstrated that recall of visually presented preload digits was superior when the words in a subsequent list were spoken by a single talker than by different talkers. In addition, a retroactive interference task demonstrated that the effects of talker variability on the recall of early list items were not due to use of talker-specific acoustic cues in working memory at the time of recall. Taken together, the results suggest that word lists produced by different talkers require more processing resources in working memory than do lists produced by a single talker. The findings are discussed in terms of the role that active rehearsal plays in the transfer of spoken items into long-term memory and the factors that may affect the efficiency of rehearsal.

The modality-match effect in recognition refers to superior memory for words presented in the same modality at study and test. Prior research on this effect is ambiguous and inconsistent. The present study demonstrates that the modality-match effect is found when modality is rendered salient at either encoding or retrieval. Specifically, in Experiment 1, visual and auditory study trials were either randomly intermixed or presented in blocks, followed by a standard (old–new) recognition test. The modality-match effect was observed for the mixed but not the blocked condition. Experiment 2 used a modality-judgment test (requiring a seen, heard, or new judgment). The resulting measure of recognition memory exhibited the modality-match effect for both list conditions. These results imply (a) that the modality-match effect is a consistent finding when modality is salient and (b) that the effect arises at retrieval rather than encoding.

Naming latencies are generally shorter for letter strings that are orthographically similar to many words than for those that have few lexical neighbors. Two experiments were conducted to explore the locus of the neighborhood size effect in a naming task. Experiment 1 showed that the neighborhood size effect was restricted to low-frequency words and was of comparable magnitude for words and for pseudowords. Experiment 2 examined performance as a function of the composition of the experimental lists. Target words were mixed with word or pseudoword fillers. The neighborhood size effect decreased in the pseudoword context relative to the word context. The data are compatible with the notion that the neighborhood size effect follows from the activation of specific word knowledge during print-to-sound computation.

In immediate serial recall, high-frequency words are better recalled than low-frequency words. Recently, it has been suggested that high-frequency words are better recalled because of their better long-term associative links, and not because of the intrinsic properties of their longterm representations. In the experiment reported here, recall performance was compared for pure lists of high- and low-frequency words, and for mixed lists composed of either one low- and five high-frequency words or the reverse. The usual advantage of high-frequency words was found with pure lists and this advantage was reduced, but still significant with mixed lists composed of five low-frequency words. However, the low-frequency word included in a high-frequency list was recalled just as well as high-frequency words. Results are challenging for the associative link hypothesis and are best interpreted within an item-based reconstruction hypothesis, along with a distinctiveness account.

It has been proposed that auditory stimuli are more temporally discriminable in memory than visual stimuli. Studies using the continual-distractor paradigm have provided both supporting and contradictory evidence for this hypothesis. The conflicting reports differed, however, in the modality of the interleaved distractor tasks. The present experiments manipulated both word and distractor-task modality. Results showed that aurally presented word lists were more sensitive to temporal schedules of presentation when the distractor task was auditory than when it was visual. The same effect was not consistently found for visually presented word lists. Such an interaction may help explain the previously reported disparate findings and suggests that the auditory modality, in the presence of silent distraction, can reduce participants' use of temporal-distinctiveness information at retrieval.

3 groups of 22 undergraduates each were asked to memorize lists of either (a) all common words, (b) all rare words, or (c) a mixed list of alternating common and rare words. In terms of trials to criterion in free recall the groups were rank ordered rare > common > mixed. The typical high-frequency easier-recall effect was reversed in the mixed list where rare words were recalled more efficiently than common words.

In 3 experiments, participants saw lists of 16 words for free recall with or without a 6-digit immediate serial recall (ISR) task after each word. Free recall was performed under standard visual silent and spoken-aloud conditions (Experiment 1), overt rehearsal conditions (Experiment 2), and fixed rehearsal conditions (Experiment 3). The authors found that in each experiment, there was no effect of ISR on the magnitude of the recency effect, but interleaved ISR disrupted free recall of those words that would otherwise be rehearsed. The authors conclude that ISR and recency cannot both be outputs from a unitary limited-capacity short-term memory store and discuss the possibility that the process of rehearsal may be common to both tasks.

The authors report 2 experiments that compare the serial recall of pure lists of long words, pure lists of short words, and lists of long or short words containing just a single isolated word of a different length. In both experiments for pure lists, there was a substantial recall advantage for short words; the isolated words were recalled better than other words in the same list, and there was a reverse word-length effect: Isolated long words were recalled better than isolated short words. These results contradict models that seek to explain the word-length effect in terms of list-based accounts of rehearsal speed or in terms of item-based effects (such as difficulty of assembling items).

Sexual differences in the hemispheric organization of verbal functions were shown in experiments with dichotic presentation of word lists, in Sternbeg's memory scanning task, in studies of EEG power and coherence while memorizing the lists of dichotically presented words. The efficiency of word retrieval and speed of memory scanning for stimuli presented to the right hemisphere were higher in women. EEG activation while memorizing words was more pronounced in men. There were negative correlations between left ear word retrieval and EEG activation in women. The author's findings showed sexual dimorphism in functional connections within the cortical regions of the brain while memorizing verbal information. The changes in coherence were in positive correlation with the efficiency of word retrieval in women and in inverse correlation in men, and this was evidence for the different physiological significance of changes in coherence in men and women. This suggests that the physiological significance of changes in coherence differs in men and women. 相似文献

Amnesic rate of decline of free recall, cued recall, and recognition of word lists with different levels of organization was investigated in 2 experiments. In Experiment 1, it was found that amnesic free recall of semantically related word lists declined at an accelerated rate, whereas free recall of lists of unrelated words declined at a normal rate. Cued recall and recognition performance of both kinds of word lists appeared to decline at a normal rate. In Experiment 2, the results of the free-recall and recognition conditions were replicated using an improved experimental design. The observed amnesic forgetting pattern is interpreted as arising from an impairment in consolidation of long-term memory for complex associations between 2 or more items and their study context that is caused by extended hippocampal system lesions.

The list-strength effect occurs when "strong" items within a list are remembered at the expense of "weak" items within that same list. Two experiments (using 185 college student Ss) showed that variably encoded words were remembered better than words repeated with the same encoding context, whether memory was measured by free recall, frequency estimates, or recognition d'. However, there was little or no evidence from any of the measures that the variably encoded words were recollected in the mixed lists at the expense of the similarly encoded words. This pattern held even though, in Exp 2, there was a list-strength effect on free recall, when list strength was manipulated by increasing the number of presentations of a word. It is concluded that the free recall results could not be accommodated by the model of memory postulated by R. M. Shiffrin et al (see record 1990-13917-001) to account for the effects of list strength. (French abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

In short-term serial recall, similar sounding items are remembered less well than items that do not sound alike. This phonological similarity effect has been observed with lists composed only of similar items, and also with lists that mix together similar and dissimilar items. An additional consistent finding has been what the authors call dissimilar immunity, the finding that ordered recall of dissimilar items is the same whether these items occur in pure dissimilar or mixed lists. The authors present 3 experiments that disconfirm these previous findings by showing that dissimilar items on mixed lists are recalled better than their counterparts on pure lists if order errors are considered separately from intrusion errors (Experiment 1), or if intrusion errors are experimentally controlled (Experiments 2 and 3). The memory benefit for dissimilar items on mixed lists poses a challenge for current models of short-term serial recall. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
