论元结构的焦点和重音关系对话语理解的影响

本研究采用韵律合适度判断和理解任务,通过两个实验探讨论元结构的焦点和重音之间的关系对话语理解的影响。实验通过操纵答句中的论元是否出现在问句中,变化问句的信息状态;通过操纵答句不同句子成份重读,变化答句的重读位置。实验结果发现:新论元负载焦点必须重读;重读论元将焦点投射到句子的高一级单元上,但动词必须重读;旧论元不负载焦点不必重读,但负载焦点的动词必须重读。     

Memory for sentences and noun phrases of extreme depth

Memory for orally presented noun phrases and sentences was investigated in two experiments. Syntactic depth (D) of the phrases and sentences was varied with D approaching the values of 7 ± 2. Consistent with recent investigations, these studies found D not to be generally related to recall of sentences, phrases, or individual words within sentences. However, recall of individual words from an adverbial noun phrase apparently was related to D. The apparent relationship is accounted for not by depth of individual words, but in terms primarily of superior noun retention and its interaction with serial position effects. In addition, conditional recall probabilities for another type of phrase, a noun phrase with prenominal adjectives, indicate stronger relationships between adjectives and the noun than between successive adjectives. It is concluded that the Yngve grammar is deficient as a psycholinguistic model.     

Processing Pitch and Temporal Structures in Music Reading: Independent or Interactive Processing Mechanisms?

Music provides a useful domain in which to study how the different attributes of complex multidimensional stimuli are processed both separately and in combination. Much research has been devoted to addressing how the dimension of pitch and time are co-processed in music listening tasks. Neuropsychological studies have provided evidence for a certain degree of independence between pitch and temporal processing, although there are also many experimental reports favouring interactive models of pitch and temporal processing. Here we extended these investigations by examining the processing of pitch and temporal structures when music is presented in the visual modality (i.e. in the form of music notation). In two experiments, musician subjects were presented with visual musical stimuli containing both pitch and temporal information for a brief amount of time, and they were subsequently required to recall both the pitch and temporal information. In Experiment 1, we documented that concurrent, unattended, pitch and rhythmic auditory interference stimuli disrupted the recall of pitch, but not time. In Experiment 2, we showed that manipulating the tonal structure of the visual presentation stimuli affected the recall of pitch, but not time. On the other hand, manipulating the metrical properties of the visual stimuli affected recall of time, and pitch to a certain extent. Taken together, these results suggest that the processing of pitch is constrained by the processing of time, but the processing of time is not affected by the processing of pitch. These results do not support either strong independence or interactive models of pitch and temporal processing, but they suggest that the processing of time can occur independently from the processing of pitch when performing a written recall task.     

Constraints on retrieval search for episodic information in children and adults

The hypothesis that a lack of structural constraint limits children's ability to use context and category cues to search associative memory for episodic information is examined in this study. Second and fifth graders and college adults were shown word triplets at acquisition and asked to recall the final target member of each triplet in a cued recall task. The manipulations concerned sources of associative structure that could constrain retrieval search. The degree to which the members of the triplets were associated was varied, as well as the kind of association, and the kind and amount of retrieval support provided in the cue, and encoding was constrained by orienting questions or was unconstrained. The results showed that children's effective use of retrieval cues was more dependent on episodic associative structure, retrieval support, and the constrained encoding of associative information than was adults'. Differences in the associative structure of information in permanent memory seemed to contribute to the results.     

Preschoolers' comprehension of goal structure in narratives

Preschool children's understanding and use of goals were studied in two experiments. Children heard stories in the presence of pictures or props. The stories were varied by goal success occurring early or late in the story, with late goal success resulting in more causal connections in the narrative. The results showed that children recalled goals spontaneously and that their recall benefited from goal structure of the stories. Pictures benefited the children when the stories were short. Enactment of the props versus static displays of the props did not enhance recall in the second experiment. Preschool children thus demonstrated ability to infer and use goal and causal information in stories for both picture and object support.     

Field articulation and working memory

This experiment assessed the proposal that performance differences associated with field independence/field articulation reflect differential efficiency in the use of a limited capacity information-processing system termed working memory. Extreme scores on a group-administered version of the embedded figures test were used to identify subjects “high” and “low” in degree of field articulation. The task required that a subject retain a series of digits for subsequent report while performing a semantic modification of a target phrase. Concurrent information load on working memory was varied in two ways: by increasing memory load from 3 to 6 digits, and by increasing the complexity of the semantic processing required. In low information load conditions no differences were found between high FA and low FA groups. In high information load conditions low FA subjects made more errors in digit recall and took longer to perform the difficult semantic modification.     

Perception and immediate recall of normal and “compressed” auditory sequences

For a fixed presentation rate, the ratio of speech-to-pause time was varied in three experiments. Ss recalled seven-digit sequences or monitored for item or order information in addition to recall. Removing 33% of the speech and substituting pause time improved recall accuracy and monitoring reaction times. The data suggest that loss of order information in recall may result from cumulative perceptual delays when adequate pause time is unavailable.

Singing can facilitate foreign language learning

This study presents the first experimental evidence that singing can facilitate short-term paired-associate phrase learning in an unfamiliar language (Hungarian). Sixty adult participants were randomly assigned to one of three “listen-and-repeat” learning conditions: speaking, rhythmic speaking, or singing. Participants in the singing condition showed superior overall performance on a collection of Hungarian language tests after a 15-min learning period, as compared with participants in the speaking and rhythmic speaking conditions. This superior performance was statistically significant (p < .05) for the two tests that required participants to recall and produce spoken Hungarian phrases. The differences in performance were not explained by potentially influencing factors such as age, gender, mood, phonological working memory ability, or musical ability and training. These results suggest that a “listen-and-sing” learning method can facilitate verbatim memory for spoken foreign language phrases.     

Encoding processes and the recall of text

Two experiments investigated the proposition that the amount of cognitive effort expended to encode information will be directly related to recall of that information. While previous research has shown that amount of processing may affect recall, these studies have generally drawn on the notion of an elaborated memory representation to explain their results. In this study, the amount of processing required to correctly interpret anaphoric relations was varied while the elaboration of the memory trace was held constant. These experiments employed a self-paced reading paradigm in which subjects read a series of short paragraphs and later were cued to recall the final sentence of each paragraph. It was found that recall was significantly improved when more processing was required to correctly interpret the anaphoric relationship expressed in the final sentence. These findings suggest that encoding processes can affect recall performance without elaboration of the memory representation.     

The representation of spatial information in memory

Following memorisation of the spatial arrangement of an array of circles, subjects were asked to recall the circles in a type of free-recall task designed to determine the structure of the memorised information. Their performance showed that the circles tended to be recalled in an order that corresponded with a top-to-bottom ordering of circles on the array. In a second experiment the input order of the circles was varied by presenting them successively. The results indicated that input order influenced recall order. The implications for hypotheses about the structure and manipulation of stored spatial information were discussed.     

Aging and Inhibition of Unconsciously Processed Information: No Apparent Deficit

Young and older adults were compared on a cued recall task designed to show effects of activation and inhibition of unconsciously processed information. The number of associates related to the target words by prior experience was varied, and the targets were studied either in the absence or the presence of meaningfully related context cues. The number of associates of the target had an effect on recall when context cues were absent during study, suggesting that the associates had been activated and encoded during study. In contrast, when context cues were present during study, no effect of the number of target associates was observed, suggesting that the associates had been inhibited during study. Comparable activation and inhibition effects were obtained for younger and older subjects. The results suggested little or no age-related deficit in inhibition when the to-be-inhibited information was unconsciously processed and not brought to conscious awareness.     

Young Children Prefer and Remember Satisfying Explanations

Research with preschool children has shown that explanations are important to them in that they actively seek explanations in their conversations with adults. But what sorts of explanations do they prefer, and what, if anything, do young children learn from the explanations they receive? Following a preliminary study with adults (N = 67) to establish materials for use with children, we addressed this question using a seminaturalistic methodology. Four- and 5-year-olds (N = 69) were dissatisfied when receiving nonexplanations to their explanatory questions, but they were satisfied when receiving explanations, and their satisfaction varied appropriately across several levels of explanatory information. Moreover, using recall as a measure of learning, whereas children typically failed to recall nonexplanations, their recall of explanatory information was consistently high and also varied appropriately across differing levels of information provided. These results confirm that children not only actively seek informative explanations in their everyday conversational interactions with adults, but they selectively retain the answers they receive.     

Alliteration and the Sacred: A Study of 'Be Fertile and Increase'

The Hebrew Bible is a richly crafted text, teeming with wonderful examples of narrative artistry, not only of how it arranges words, but how it arranges sounds. If the structure of the narrative can help us interpret possible meanings, then it would seem that the phonetic elements of the text can also assist us in the larger task of interpretation (an underexploited resource for the biblical scholar). This article gives an example of how the rhythmic repetition of sound elements contribute to interpretation through the example of the richly alliterative phrase, peru urbu umil'u . The article examines its occurrences in Genesis. It is found ten times (in several grammatical forms), five in the Primeval History, five in the Patriarchal History. Close readings of these occurrences are used to show how the rhythmic arrangement of sounds contributes to the development of the themes at critical junctures of the narrative. When the phrase 'be fruitful and multiply' is found in direct speech by God to a human, the phrase is endowed with a tremendous amount of alliteration; when the phrase is found in human speech there is a great deal less. In this example, then, it would seem alliteration is being used to distinguish human from divine speech. As modern readers, it is very easy for us to forget the oral context in which these stories emerged, that most people heard, rather than read, them. So it seems completely reasonable to suggest that, in this one example, phonetic artistry is being used to make it easier for the listener of the text to understand that he has just heard the voice of God.     

Additive and interactive effects in memory for subject-performed tasks

Abstract

Three experiments were carried out to explore reasons for the superior recall and recognition of subject-performed tasks (SPTs) relative to memory for the equivalent verbal commands. In Experiment 1, list structure was varied; list structure affected recall, but the variable did not interact with the SPT/command manipulation. The same absence of an interaction was found in Experiment 2 with respect to different retrieval conditions and also with respect to the age of adult subjects. Experiment 3 confirmed that the age difference was as large for SPTs as it was for verbal commands. In addition, an interaction between SPT/command and levels of processing was found in Experiment 3. Differences between the additive and interactive patterns of results are discussed in terms of SITS contributing both additional (possibly motoric) information and also conceptual information that overlaps with information added by other variables.     

Is recitation an effective tool for adult learners?

The effects of recitation on subsequent recall were examined in 4 experiments modeled after those of Gates (1917). Participants underwent a study phase, a recitation phase, and a test phase. During the recitation phase participants were to attempt to recall the previously studied material and then to restudy it when they could not recall any new information. They were encouraged to switch between recalling and restudying. The proportion of the total acquisition time that was spent in recitation was varied. Unlike the classic findings reported by Gates (1917) in schoolchildren, there was no consistent evidence that recitation enhanced learning in these adult learners.     

The relation between discriminability and memory for vowels,consonants, and silent-center vowels

People remember lists of vowel-contrasting syllables better than lists that vary only in stop consonant identity. Most views suggest that this difference is due to the structure of immediate memory and the greater discriminability of vowels compared with consonants. In all of these views, there is a presumed systematic relationship between discriminability and recall so that the more discriminable an item, the better that item should be recalled. The 11 experiments reported here measured the relative discriminability of and compared serial recall for (1) intact syllables that varied only in the medial vowel, (2) intact syllables that varied only in the initial consonant, and (3) syllables with the center vowel replaced by silence (so-called silent-center vowels). When item discriminability, as measured by identification, was equated for consonant-contrasting and silent-center lists, serial recall performance was also equal. However, even when the vowels were less discriminable than the consonants or silentcenter vowels, serial recall performance for the vowels was still better. These results are problematic for theories based on acoustic discriminability but can be explained parsimoniously by Nairne’s (1990) feature model.     

In Search of Gender Recency: Evidence from the Production of Pronouns

This study investigated whether retrieval of a noun's grammatical gender benefits from having retrieved that information recently. In response to picture stimuli, participants produced gender-marked pronouns under various priming conditions. The primes differed in that they either necessitated retrieval of grammatical gender (indefinite noun phrase/pronoun) or did not (noun); when they required gender retrieval, they varied in whether they involved access to the same morpheme (pronoun) or a different morpheme (indefinite noun phrase). Relative to an unprimed condition, faster responses were obtained in each condition. Pronoun primes facilitated pronoun naming more than the other prime types, but no difference was observed between noun primes and indefinite noun phrase primes. Thus, although the experiment was sensitive to priming processes, there was no evidence for morpheme-independent gender priming.     

What effect can rhythmic finger tapping have on the phonological similarity effect?

The effects of rhythmic finger tapping on the phonological similarity effect were investigated in two experiments. In both, subjects were tested for serial recall of visually presented letter sequences that were either phonologically similar or dissimilar. The letter sequences had to be remembered under three tapping conditions: right-hand tapping, left-hand tapping, and a no-tapping control. Experiment 1 showed clear phonological similarity effects in both the control and the left-hand tapping conditions, but not in the right-hand tapping condition, when recall responses were written with the right hand. When the number of tapping practice trials was fixed at two and recall was vocal in Experiment 2, the phonological similarity effect was eliminated in both the right-hand and the left-hand tapping conditions. These results suggest that some form of speech motor programs played an important role in serial recall.
