The effects of elaboration on recognition memory

Two experiments were conducted to examine the effects of elaboration on recognition memory. Subjects were given either simple or complex sentences to learn and were tested for recognition of either an individual target word or the entire sentence. Complex sentences supported better recognition performance only when the test item allowed the subject to easily redintegrate the initial encoding context, either by re-presenting the encoded sentence as the test item or by constructing sentences such that the component words of the sentence could be easily redintegrated from an individual target item. It was suggested that complex, elaborate encoding established a richer trace, but that this richness can be utilized to enhance recognition only when the test conditions permit a reinstatement of the original encoding context.     

Semantic integration and context

Context effects in recognition memory were examined by manipulating the semantic integration of sentential contexts. Subjects studied words embedded in congruous, incongruous, and anomalous sentences and were tested for recognition of the targets in either the same or changed contexts. Recognition was impaired if the test item appeared in a new sentence, and the extent of the decrement was greatest for congrous sentences. The results suggest that consistence with past experience affects the integration of the representation, and that the stronger the integration, the more difficult it is to recognize the target in a new context. The data are discussed in terms of a relative specificity of encoding effect.     

Imagery effects and semantic similarity in sentence recognition memory

The idea that subjects often use imagery to discriminate semantically similar sentences was tested in three experiments. In the first experiment, subjects heard subject-verb-object sentences in the context of either a comprehension task or an image-generation task. Their memory for the sentences was tested using a two-alternative forced-choice recognition test in which different types of distractor sentence were used. A sentence semantically similar to the target sentence was one type; a sentence with the same subject and object nouns as the target sentence, but dissimilar in meaning, was another type; and a sentence similar in meaning to one of the stimulus sentences, but not to the target sentence, was a third type. The results showed that the image-generation instructions enhanced later recognition performance, but only for semantically similar test items. A second experiment showed that this finding only holds for high-imagery sentences containing concrete noun concepts. A third experiment demonstrated that the enhanced recognition performance could not be accounted for in terms of a semantic model of test-item discrimination. Collectively, the results were interpreted as providing evidence for the notion that subjects discriminate the semantically similar test items by elaborating the sentence encoding through image processing.     

Face recognition: Effects of study to test maintenance and change of photographic mode and pose

Facial recognition performance was examined as a function of changes in the target between initial exposure (study) and a subsequent recognition test. Photographic mode (colour vs. black and white) was changed in Experiments 1 and 2 and pose (front vs. profile) was changed in Experiment 2. The predictions of three information quantity models and of encoding specificity were contrasted. The information hypotheses predict that colour photographs will be better recognized when presented in colour than in black and white; the more specific predictions differ depending on the modes at study and test. Encoding specificity predicts recognition performance will be better when study and test modes are the same. The results of Experiment 1 showed that performance was highest when pictures remained in the same mode from study to test, and decreased when the mode was changed. Change of mode was particularly detrimental when the faces were studied in black and white and tested in colour. Experiment 2 showed a pattern of results also in accord with encoding specificity. The photographic mode and pose effects did not interact. Change of pose had a greater effect than change of photographic mode. Experiment 2 did not replicate the transformation asymmetry found in Experiment 1. The results indicate that for facial recognition memory, change lowers recognition, but the magnitude of the effect depends on the kind of change.     

Tests of the generality of the principle of encoding specificity

Two empirical tests of the principle of encoding specificity are reported. In Experiment I, the normative strength of the cues presented on the input and on the recall trial was varied factorially. To lessen the emphasis on strictly associative learning, only half the items were cued in each phase of the study-recall cycle. Recall was higher when the cues remained the same than when they changed. However, regardless of the condition of input cuing, strong output cues were substantially more effective than weak ones. In Experiment II, the to-be-remembered words were shown in the presence of weak cues on the input trial. Recognition in the context of strong extralist cues was compared with recall to the original input cues. On the test of cued recognition, the target words were either generated by the subjects as free associates or presented to them as items on a test constructed by the experimenter. Contrary to previous findings, recall was not found to be superior to recognition. The phenomena of cue-dependent forgetting that have been interpreted as evidence for the principle of encoding specificity appear to have limited generality.     

The effects of recall and recognition test expectancies on the retention of prose

The hypothesis that people expecting recall and recognition employ different encoding processes was tested in two experiments using prose materials. In Experiment 1, unrelated sentences were used, and in Experiment 2, a short essay was used. The results indicated that a recall test expectancy led to greater sentence recall than a recognition test expectancy. No evidence was found to support the hypothesis that people expecting recall and recognition retained different types of information contained in sentences. In Experiment 2, the effects of test expectancy were analyzed as a function of the structural importance and rated comprehensibility of sentences. A main effect of test expectancy was found in sentence recall, replicating the results of Experiment 1. Also, people expecting recall tended to remember greater detail than did people expecting recognition. The results suggested that encoding processes vary as a function of test expectancy and that the appropriateness of encoding depends on the type of test received.     

Varieties of frequency interference in children's recognition of sentence information

The memory of fourth-grade children (9 years, 10 months of age) for information contained in target sentences presented 24 hours earlier was tested by multiple-choice recognition items each consisting of a question about a target sentence followed by three response options. The options consisted of the correct word from the sentence, a new word, and an old, incorrect word that was contained in another sentence on the study trial. The results indicated that the amount of interference produced by old information depended upon the relationship between the sentence in which the old information occurred and the target sentence—being the least when the two were unrelated; the most when the two shared the same subject noun (which also occurred in the stem of the test item for the target sentence); and intermediate when the subjects of the two sentences were synonyms. The interference produced by these manipulations was moderated by instructional strategies and the distance between the target sentence and its variation. The experiment establishes the validity of contextual frequency accrual, a construct logically necessary in extending frequency theory to recognition of information contained in sentences.     

A Brief Pause between a Tagline and Brand Increases Brand Name Recognition and Preference

This paper explores the outcome of the visual encoding of brands in meaningful sentences (i.e. in taglines) on brand name recognition and preference. In this paper, it is shown that, above and beyond the role of conceptual priming during encoding at increasing recognition memory, there is a role of creating a temporal delay, or pause, between meaningful cues in the sentence and a key word (Experiment 1) or brand (Experiments 2a and 3) on memory. The pause is also associated with increased preference towards brands (Experiment 2b). These findings demonstrate a new way to enhance recognition of brand names that is not due to a pure generation effect but rather by increasing attention, which increases processing fluency of the target.

Acquisition-test interactions between

The effects of changes in context on recognition memory were investigated in two experiments. In Experiment 1 target items were embedded in congruous or incongruous sentence frames and then tested in the original, new congruous, or new incongruous contexts. Experiment 2 included a third encoding condition; targets were also embedded in abstract definitional sentences. Both experiments revealed a reliable crossover interaction between the initial encoding condition and the mode of the changed context. Congruous items were recognized better in new congruous contexts, whereas incongruous items were recognized better in new incongruous contexts. Recognition of definitional items was equally impaired by both context changes. The results suggest the importance of the symmetry between acquisition and test encoding dimensions. These experiments also point out the need to distinguish between different ways in which the concept “integration” is used in current research.     

When are social judgments made? Evidence for the spontaneousness of trait inferences

Do people make trait inferences, even without intentions or instructions, at the encoding stage of processing behavioral information? Tulving's encoding specificity paradigm (Tulving & Thomson, 1973) was adapted for two recall experiments. Under memory instructions only, subjects read sentences describing people performing actions that implied traits. Later, subjects recalled each sentence under one of three cuing conditions: (a) a dispositional cue (e.g., generous), (b) a strong, nondispositional semantic associate to an important sentence word; or (c) no cue. Recall was best when cued by the disposition words. Subjects were unaware of having made trait inferences. Interpreted in terms of encoding specificity, these results indicate that subjects unintentionally made trait inferences at encoding. This suggests that attributions may be made spontaneously, as part of the routine comprehension of social events.     

Encoding specificity and unidirectional associates in cued recall

The first of two experiments confirmed the earlier findings of Humphreys and Galbraith (1975), that under silent-study encoding instructions, words assessed as strong elicitors of target words are effective extralist retrieval cues, whereas words assessed as weak elicitors are not. In the second experiment, predictions from the encoding specificity principle were confirmed with respect to the effectiveness of forward and backward retrieval cues in recall. Contrary to the conclusions of Humphreys and Galbraith, forward and backward unidirectional associates were equally effective as retrieval cues, provided subjects engaged in associative encoding (generated associations to the target words) at storage.     

The generalizability of context effects on word recognition: A reconsideration of the roles of parafoveal priming and sentence context

In three experiments, subjects named target words preceded by congruous, incongruous, or neutral sentence contexts. There was no evidence that the recognition of the target word was affected by the semantic characteristics of a word presented immediately to the right of it. The nature of the preceding sentence context did affect target-naming speed. However, the magnitude of the context effect was considerably smaller in these experiments, in which nonterminal target words were used, than in previous experiments in which the target word was always the final word of the sentence, was highly predictable from the context, and was often semantically related to words in the sentence. The implications of these two findings for theories of reading and context effects are discussed.     

The effect of context on discrimination and bias in recognition memory for pictures and words

When the context accompanying a to-be-remembered word is changed between study and test, recognition memory is impaired. The deleterious effect of context change on recognition memory can be viewed as support for encoding specificity theory, semantic theory, or the existence of two bases for recognition. A fourth possible interpretation, examined here, is that the effect of context change on recognition memory is due to an accompanying change in response bias, rather than a "true" decrease in sensitivity to old and new items. In two experiments, the effect of context change on discrimination and bias in recognition of simple line drawings and their names was examined. Bias was measured using two measures shown by Snodgrass and Corwin (1988) to be theoretically independent of their associated discrimination measures. Context change produced marked conservatism in response bias in both experiments but demonstrated an effect on discrimination in the second experiment only. The shift from a neutral to a conservative response strategy as a result of context change may also be seen in other experiments, in which the same experimental paradigm was used with a variety of stimulus materials. We suggest that the major effect of context manipulation is to produce a change in bias. A stimulus in a familiar environment appears to be more familiar than a stimulus in a strange environment, regardless of its old/new status. In addition, there appears to be a true decrease in discrimination with context change, but this is more difficult to detect. The finding that pictures, which are less polysemous than words, are as affected by context change as words are supports encoding specificity theory over semantic theory.     

Influence of motoric encoding on forgetting function of memory for action sentences in patients with Alzheimer's disease

This study assessed whether verbal encoding and motoric encoding have different effects on the forgetting function for action sentences of patients with Alzheimer's disease. Subjects were 13 healthy elderly adults and 10 patients diagnosed with Alzheimer's disease. Three tasks were used: verbal tasks, subject-performed tasks, observed tasks. On the verbal tasks, subjects only heard the action sentences as read to them. On the subject-performed tasks, subjects heard, then performed each action sentence. On the observed tasks, subjects heard the action sentences read while observing the object mentioned in each action sentence. After presentation of each task, subjects conducted immediate and 30-min. delayed recall tests, and then a recognition test. Analysis indicated recall performance for subject-performed tasks was significantly better than that for verbal tasks and observed tasks at both immediate and delayed recall in each group. On the recognition test, carrying out the action had no effect, but for both groups recognition was enhanced by observing the object. Elderly adults performed significantly better than patients on all tasks of recall and recognition. However, the results indicate that patients with Alzheimer's disease can use multimodal resources from motoric encoding even if time passes.     

Encoding specificity revisited: the role of semantics.

Three experiments examined the effects of semantic characteristics of word pairs on memory using the encoding specificity paradigm. The paradigm involved four phases: (a) an encoding phase to relate cues and targets, (b) a phase in which words were generated to new cues, (c) a phase for recognition of generated targets, and (d) a cued-recall phase using the original encoding cues. Encoding pairs were classified a priori as either semantically similar (e.g., alluring-PRETTY), semantically contrasting (e.g., drab-PRETTY), or semantically unrelated (e.g., sore-PRETTY). Generation pairs were classified a priori as either semantically similar (e.g., beautiful-PRETTY) or semantically contrasting (e.g., ugly-PRETTY). For recall, the results showed that both the semantic relations between the encoding cue and target and the reprovision of the encoding cue at retrieval were important factors. In the case of recognition, however, both the semantic congruence between the encoding and generation contexts and the amount of semantic elaboration provided by the encoding context were important factors.     

Rapid extraction of gist from visual text and its influence on word recognition

Two experiments explored rapid extraction of gist from a visual text and its influence on word recognition. In both, a short text (sentence) containing a target word was presented for 200 ms and was followed by a target recognition task. Results showed that participants recognized contextually anomalous word targets less frequently than contextually consistent counterparts (Experiment 1). This context effect was obtained when sentences contained the same semantic content but with disrupted syntactic structure (Experiment 2). Results demonstrate that words in a briefly presented visual sentence are processed in parallel and that rapid extraction of sentence gist relies on a primitive representation of sentence context (termed protocontext) that is semantically activated by the simultaneous presentation of multiple words (i.e., a sentence) before syntactic processing.     

Older adults can inhibit high-probability competitors in speech recognition

Younger and older adults identified a series of target words spoken in sentence contexts from their onsets only (i.e., word-onset gating). Sentences were drawn from published norms so that the contextual probabilities of the final words were known. the target words were always the second most probable responses to the sentence contexts, and the probabilities of the target words and the most likely alternatives were systematically varied. Results showed that older adults required more word-onset information for correct recognition, and their responses were more affected by the probability of the occurrence of the target word, supporting previous suggestions that older listeners differentially rely on contextual support in spoken word recognition. Contrary to the Inhibition Hypothesis, however, that older adults have especial difficulty suppressing irrelevant information once it is activited, elders' ability to recognize the target was not particularly disrupted by the presence of a high-probability competitor.     

篇章阅读理解中句子边界对整体连贯性的影响

通过四个实验考察句子边界对整体连贯性的影响。实验运用不一致程序(inconsistent paradigm)进行。实验一结果发现,当目标行1(target line)不是一个完整句子时,被试阅读完目标行2(post-target line)后才会意识到目标行1中的不一致。实验二结果发现,当目标行1是一个完整句子时,被试阅读完目标行1后就可立刻意识到其中的不一致,但探测词的反应时在两种条件下则并没有明显差异。这两个实验的结果表明,句子边界作为一种信号,提示读者在阅读下一句子前要完成当前句子的整合加工。实验三结果发现,目标行1以一个无关词(如然后)结束时,被试阅读完目标行1后也可立刻注意到其中的不一致,这表明句号对背景信息的整合不是必需的。实验四考察了分号的作用,结果显示:被试阅读完目标行1后并没有意识到其中的冲突。根据本研究的结果,可以推测句号在理解过程中起着重要影响,而其它句子边界(如:分号)的作用则并不明显。     

Determinants of cued recall

This paper reports two cued recall experiments in which the degree of preexperimental associative strength between rhyming cues and their respective targets is manipulated whilst holding the extent of informational overlap between them constant. Both experiments show that strong rhyming cues are more efficient than weak rhyming cues in eliciting target retrieval in both a short-term and a long-term memory situation. The results are interpreted as consistent with the generationrecognition theory of retrieval and inconsistent with predictions made by the encoding specificity principle. It is therefore suggested that caution must be applied when extending the encoding specificity principle to experimental situations other than that from which it is derived. Implications for the distinction between scanning and reconstructive modes of retrieval are also briefly considered.     

Differential cognitive processing of Kanji and Kana words: do orthographic and semantic codes function in parallel in word matching task.

Relative engagements of the orthographic and semantic codes in Kanji and Hiragana word recognition were investigated. In Exp. 1, subjects judged whether the pairs of Kanji words (prime and target) presented sequentially were physically identical to each other in the word condition. In the sentence condition, subjects decided whether the target word was valid for the prime sentence presented in advance. The results showed that the response times to the target swords orthographically similar (to the prime) were significantly slower than to semantically related target words in the word condition and that this was also the case in the sentence condition. In Exp. 2, subjects judged whether the target word written in Hiragana was physically identical to the prime word in the word condition. In the sentence condition, subjects decided if the target word was valid for the previously presented prime sentence. Analysis indicated that response times to orthographically similar words were slower than to semantically related words in the word condition but not in the sentence condition wherein the response times to the semantically and orthographically similar words were largely the same. Based on these results, differential contributions of orthographic and semantic codes in cognitive processing of Japanese Kanji and Hiragana words was discussed.
