Passage organization and imposed learning strategies in comprehension and recall of connected discourse

Ninety-nine Ss were assigned randomly to learn a passage comprised of six paragraphs in which the statements were organized by concept name, or concept attribute, or in which the statements were scrambled. Each complete passage contained the same 36 statements. These treatments were orthogonally crossed with instructions to employ a name clustering strategy, an attribute clustering strategy, or a subjectively determined organizing strategy. Three learning trials were administered, each of which was followed by free recall. Passages organized by concept name were found to result in greater recall than passages organized by attributes. The name clustering strategy was more dominant than the attribute clustering strategy, lncongruence between passage organization and advocated clustering strategy resulted in greater recall than did congruency. Implications of these results for cognitive processing of information are discussed     

Pictorial context and the recall of pronoun sentences

Summary Acting on the assumption that pictures affect the processing of sentences only when providing additional information, the authors used pictures, which in an earlier experiment had failed to influence the retention of noun sentences, as illustrations to semantically undefined pronoun sentences, thus establishing a distinct information gradient between sentence and picture. These pronoun sentences were presented to 48 subjects for recall, in four pictorial conditions: without picture, with unambiguous picture, with subject-ambiguous, and with object-ambiguous picture. As hypothesized, picture-less pronoun sentences were more poorly recalled than picture-enriched pronoun sentences. Moreover, sentences accompanied by subject-ambiguous pictures, in which the grammatical subject could not be clearly identified, scored lower than the same sentences with unambiguous or object-ambiguous pictures. The findings invite a communication-theory analysis of the experimental situation, for which Searle's theory of speech acts is invoked.The authors gratefully acknowledge the assistance of Mr. B.

Context effects and the recall of comparative sentences

Clark and Card (1969) have proposed that semantic components underlie memory for comparative (C) sentences. To test this hypothesis, six groups of 15 Ss each were given different sets of C sentences. In line with the theory, Ss tended to remember unmarked adjectives better than marked ones and positive constructions better than negatives. However, contrary to the theory, they also tended to bias their responding either toward the negative or the equative form. A two-stage theory of recall, based on the memory schema-memory trace distinction, is proposed to account for these data.     

Performance structures in the recall of sentences

Two experiments were conducted to ascertain whether subjects’ recall of sentences reflects more closely their surface structure, as Johnson (1965, 1969) and others have predicted, or their performance structure, as Grosjean, Grosjean, and Lane (1979) have proposed. The results clearly show that, as for pausing and parsing, transitional error probability (TEP) in the rote recall of sentences reflects the product of two, sometimes conflicting, demands on processing: the need to respect the linguistic surface structure of the sentence and the need to balance the length of the constituents. The structures obtained from TEPs were similar to those obtained from other tasks (pausing and parsing), showing that performance structures are not task specific. In addition, the presence of deletable elements in the sentences (such as adjectives and adverbs) was closely associated with high TEPs.     

Ear differences in the recall of monaurally presented sentences

Using a short-term memory paradigm, with an interpolated task, college students were required to recall monaurally presented sentences. Four types of sentences, representing a factorial combination of Surface Structure, either right-branching or self-embedded, and Semantic Constraint, either semantically normal or semantically anomalous, were used. Analysis of recall data indicated a right ear advantage (REA). This result clearly contradicts Kimura's (1967) “perceptual rivalry” hypothesis which assumes that auditory conflict as induced, for example, through dichotic stimulation, is necessary for producing a REA in verbal processing. It was concluded that short-term and attentional factors contributed to the presence of the REA. No interactions involving Ear and either Surface Structure and/or Semantic Constraint were obtained and, therefore, no conclusion could be drawn regarding the view (Kimura and Folb, 1968; Studdert-Kennedy and Shankweiler, 1970) that the lateralized speech encoding mechanisms operate solely at a phonemic or subphonemic level.     

Idioms in sentences: Effects of frequency,literalness, and familiarity

This study investigated the relationship between subjective frequency of literal usage (literalness), subjective frequency of figurative usage (familiarity), and mean Kucera and Francis (1967) word frequency for idiom phrases. Kucera and Francis frequency was found to be independent of both familiarity and literalness. Furthermore, it was found that literalness, but not the Kucera and Francis frequency of the words in the phrase, affected reading time for literal uses of idioms. For figurative uses of idioms, familiarity and written frequency interacted. A model of idiom processing consistent with the current results and previous results is proposed. In addition, subjective familiarity and literalness norms are provided for 245 idioms.Portions of the normative study were based upon subjects in Schweigert and Cronk (1992).     

Prediction accuracy of text recall: Ease, effort and familiarity

Prediction accuracy of text recall was studied in two experiments. Text characteristics (i.e., consistency and distinctiveness) were manipulated in Experiment 1, and familiarity with the reading-task in Experiment 2. The results were also analyzed and discussed in terms of easy processing (Experiment 1), and in terms of increased and more active processing (Experiment 2). Text characteristics did not affect prediction accuracy. However, being familiar with the reading-task led to good and long-lasting prediction accuracy. Thus, subjects reading a school-book text, instructed to learn the contents of it demonstrated reliable memory awareness, both for immediate recall and for delay of one week. It was also suggested that increased processing demands and active reading enhances prediction accuracy.     

The influence of prosody on the recall of monaurally presented sentences.

Semantically anomolous sentences, which were spoken prosodically or in an even monotone, were presented monaurally and recalled after 5 sec of interpolated counting. Recall was superior in the Prosody condition, and performance in the Monotone condition showed no improvement when subjects were given prior knowledge of the syntactic structure. Also, a right ear advantage was found in the Prosody condition. The influence of prosody was attributed to its role in directing attention and providing continuity during memorization of the sentences, this being more effective when the information was received by the language hemisphere from the right ear.     

Enhancing individual and collaborative eyewitness memory with category clustering recall

Most crimes have multiple eyewitnesses. The police typically interview co-witnesses separately. In time-sensitive investigations, this could slow down evidence accumulation. Having co-witnesses collaboratively recall a crime could potentially expedite evidence accumulation. However, past research shows that collaborative group members often have conflicting retrieval strategies that disrupt each other, degrading overall recall. This cost could potentially be overcome by aligning group members’ retrieval strategies with category clustering recall (CCR), which is a retrieval strategy where information is recalled from a series of forensically relevant categories (e.g., recalling the protagonists’ appearance, then actions). This study examined the costs and benefits of collaborative eyewitness memory by having collaborative pairs of strangers, nominal pairs (i.e., two individuals whose recall is pooled) and lone individuals watch a crime and recall it using free recall or CCR. The collaborative pairs recalled the crime faster than the nominal pairs. They also recalled more correct information than individuals but less than nominal pairs, irrespective of the retrieval method. There is therefore a speed-recall completeness trade-off when collaborative groups recall crimes. Importantly, all participants recalled more correct information when using CCR. This provides initial evidence suggesting that CCR is superior to free recall. Further research examining CCR’s benefits is recommended.     

Retrieval-induced forgetting in recall and recognition of thematically related and unrelated sentences

In three experiments, we assessed the effects of type of relation and memory test on retrieval-induced forgetting of facts. In Experiments 1 and 2, eight sets of four shared-subject sentences were presented for study. They were constructed so that half were thematically related and half were unrelated. A retrieval practice phase required participants to recall a subset of the studied sentences. In the final test, the participants were prompted to recall all the sentences (character cued in Experiment 1 and character plus stem cued in Experiment 2). The results showed that the retrieval-induced forgetting (RIF) effect was similar for thematically related and unrelated sentences, indicating that the presence of episodic relations among the sentences was sufficient to produce the effect. In Experiment 3, a recognition task was introduced and the RIF effect emerged in accuracy as well as in latency measures. The presence of this effect with item-specific cues is difficult to accommodate for noninhibitory theories of retrieval.     

The recall of affirmative and negative sentences in an incidental learning task

This experiment examined the recall of positive and negative information in an incidental learning task. The two main findings were that a significantly greater number of affirmative than negative clues were correctly recalled and that the majority of errors took the form of conversions from negative to affirmative, independently of meaning. The difficulty associated with the negative clues was explained in terms of their inappropriateness in the situation, namely in the absence of any prior expectations.     

Recopition memory for syntactic and semantic aspects of connected discourse

This study investigates the pattern of retention of syntactic and semantic information shortly after comprehension of connected discourse. Ninety-six Ss listened to 24 taped passages and, after each passage, heard one recognition test sentence which was either identical to a sentence that had occurred in the passage, or was changed in some slight way. The Ss responded “identical” or “changed,” rated their confidence, and classified changes as “meaning” or “form.” Two independent variables were manipulated: (1) The relationship between the original sentence in the passage and the test sentence. The test sentence was (a) semantically changed, (b) changed from active to passive voice or vice versa, (c) formally changed in other ways that did not affect the meaning, or (d) unchanged. Each sentence appeared in all change types. (2) The amount of interpolated material between the original and test sentences was zero, 80, or 160 syllables of connected discourse which was a continuation of the passage. Each S heard passages representing all levels of each variable. All combinations of particular passages, relationship of original and test sentence, and amount of interpolated material were tested. When the test sentence was heard immediately after the original, retention was high for all test types. But after 80½160 syllables, recognition for syntactic changes had dropped to near chance levels while remaining high for semantic changes. Even when the meaning of a sentence was remembered, formal properties that were not necessary for that meaning were forgotten very quickly. The results suggest that the original form of the sentence is stored only for the short time necessary for comprehension to occur. When a semantic interpretation has been made, the meaning is stored. Thus the memory of the meaning is not dependent on memory of the original form of the sentence.     

Semantic facilitation across sensory modalities in the processing of individual words and sentences

The effect of semantic priming upon lexical decisions made for words in isolation (Experiment 1) and during sentence comprehension (Experiment 2) was investigated using a cross-modal lexical decision task. In Experiment 1, subjects made lexical decisions to both auditory and visual stimuli. Processing auditorily presented words facilitated subsequent lexical decisions on semantically related visual words. In Experiment 2, subjects comprehended auditorily presented sentences while simultaneously making lexical decisions for visually presented stimuli. Lexical decisions were facilitated when a visual word appeared immediately following a related word in the sentential material. Lexical decisions were also facilitated when the visual word appeared three syllables following closure of the clause containing the related material. Arguments are made for autonomy of semantic priming during sentence comprehension.     

Immediate and delayed recall of visually presented sentences: evidence for the involvement of phonological information

The lure intrusion effect refers to the observation that lexical priming affects recall of sentences. This effect is taken as evidence against the contribution of surface information, even with immediate sentence recall. Recently, Rummer and Engelkamp (2003a) demonstrated that this effect, which is usually observed under rapid serial visual presentation (RSVP), does not appear under immediate recall of auditorily presented sentences. This finding indicates that surface information (i.e., phonological or acoustic-sensory information) can contribute to immediate sentence recall. So far, however, the findings do not allow for a decision on whether phonological and/or acoustic-sensory information is used in immediate sentence recall. In order to dissociate the two kinds of surface information, an experiment was conducted in which immediate and delayed recall were tested for sentences that were visually presented for a longer period of time than in RSVP. This kind of presentation should support phonological representations, but does not allow for acoustic-sensory representations. The findings showed a smaller intrusion effect for immediate than for delayed recall. This indicates that, if available, phonological information is involved in immediate sentence recall thereby reducing the lure intrusion effect. Furthermore, the findings support the assumption that the phonological trace provided via RSVP reading is weaker than in normal reading.
