Previous Demonstration

It may be inferred from reaction time studies that the location of emphasis on nouns and noun phrases facilitates their comprehension (understanding and memory). However, we know of no previous demonstration of improved passage comprehension in normal listeners associated with emphasis placement. The present experiment examined effects of emphasis on comprehension of 12 passages that were read aloud and tape recorded. Emphasis placement was varied by splicing sentences containing emphasized or nonemphasized noun phrases into passages without altering the wording of the passages. These passages, contrasting in emphasis, were presented to 60 listeners. Comprehension was measured with multiple-choice, recognition questions that required subjects to link ideas across sentences. Comprehension was accurate significantly more often when correct response alternatives had been emphasized (71%), than when incorrect alternatives had been emphasized (56%), or no emphasis occurred in passages (57%). Findings reflect enhanced comprehension of emphasized items in terms of their meaning links to other concepts presented in passages. Results support the pragmatic assumption that the role of emphasis is to delineate constituents important in discourse meaning.

Reading and writing performance was observed in 30 adult aphasic patients to determine whether there was a significant difference when stimuli and manual responses were varied in the written form: cursive versus manuscript. Patients were asked to read aloud 10 words written cursively and 10 words written in manuscript form. They were then asked to write on dictation 10 word responses using cursive writing and 10 words using manuscript writing. Number of words correctly read, number of words correctly written, and number of letters correctly written in the proper sequence were tallied for both cursive and manuscript writing tasks for each patient. Results indicated no significant difference in correct response between cursive and manuscript writing style for these aphasic patients as a group; however, it was noted that individual patients varied widely in their success using one writing form over the other. It appeared that since neither writing form showed better facilitation of performance, the writing style used should be determined according to the individual patient’s own preference and best performance.

Chemical Availability

Lack of detailed understanding of the growth mechanism of CsPbBr3 nanocrystals has hindered sophisticated morphological and chemical control of this important emerging optoelectronic material. Here, we have elucidated the growth mechanism by slowing the reaction kinetics. When 1-bromohexane is used as an alternative halide source, bromide is slowly released into the reaction mixture, extending the reaction time from ~3 seconds to greater than 20 minutes. This enables us to monitor the phase evolution of products over the course of reaction, revealing that CsBr is the initial species formed, followed by Cs4PbBr6, and finally CsPbBr3. Further, formation of monodisperse CsBr nanocrystals is demonstrated in a bromide-deficient and lead-abundant solution. The CsBr can only be transformed into CsPbBr3 nanocubes if additional bromide is added. Our results indicate a fundamentally different growth mechanism for CsPbBr3 in comparison with more established semiconductor nanocrystal systems and reveal the critical role of the chemical availability of bromide for the growth reactions.<br>

Unstructured Play

ABSTRACTSeventeen of a sample of 30 precocious talkers aged 1;8 produced at least one pronoun reversal (I/you) during unstructured play. This finding led to an examination of the role of cognitive and linguistic individual differences as well as contextual factors and processing complexity as determinants of pronoun reversal. Contrary to predictions derived from previous hypotheses, there were few differences between reversers and non-reversers, other than higher use of second person forms by reversers. Reversals were more likely to occur in certain contexts: semantically reversible predicates with two noun phrases, and in imitations (though the rate of imitation was lower overall in reversers). We propose that pronoun reversals commonly result from a failure to perform a deictic shift, which is especially likely when children's psycholinguistic processing resources are taxed. Children who did not produce any pronoun reversals tended to avoid pronoun use, especially second person forms. Overt reversal may thus reflect a risk-taking approach to language acquisition, which may be particularly characteristic of precocious children.

AbstractThe morphological system of cardinal numerals in Modern Hebrew is currently undergoing rapid changes, enabling linguists to unravel the forces shaping the change as it takes place. In the free forms, gender marking on numerals is neutralized by collapsing both masculine and feminine forms into one paradigm, the feminine paradigm. In the bound (definite) forms, an opposite direction is attested, in that at least for some numerals, the masculine forms become more prevalent. The study reported here aims to determine whether the factor determining the change is prosodic or functional in nature, by eliciting production and grammaticality judgments of noun phrases containing bound numerals from five different age groups of native speakers. The results suggest that prosody plays a role in shaping the change, as forms with penultimate stress are favored over those with ultimate stress. In addition, processes of production and processes of grammaticality judgments seem to be subject to different kinds of constraints. This state of affairs indicates that the tension between the tendencies toward simplification on the one hand and maximal distinctness on the other occurs at the morphological level as well.

Verb Meaning

AbstractExperimental research has shown that English-learning children as young as 19 months, as well as children learning other languages (e.g., Mandarin), infer some aspects of verb meanings by mapping the nominal elements in the utterance onto participants in the event expressed by the verb. The present study assessed this structure or analogical mapping mechanism (SAMM) on naturalistic speech in the linguistic environment of 20 Spanish-learning infants from Argentina (average age 19 months). This study showed that the SAMM performs poorly – at chance level – especially when only noun phrases (NPs) included in experimental studies of the SAMM were parsed. If agreement morphology is considered, the performance is slightly above chance but still very poor. In addition, it was found that the SAMM performs better on intransitive and transitive verbs, compared to ditransitives. Agreement morphology has a beneficial effect only on transitive and ditransitive verbs. On the whole, concerns are raised about the role of the SAMM in infants’ interpretation of verb meaning in natural exchanges.

In 1960 Henry and Rogers reported reaction time (RT) increased with increased response complexity while response alternatives were held constant. The purpose of the present study was to observe the effects of RT and movement time (MT) when subjects attempted to separate initiation of a task from the subsequent movement response, 24 subjects performed a ball-striking movement in response to an auditory stimulus. In the experimental condition the subjects were instructed to complete initiation as quickly as possible and then make a separate subsequent movement to strike a ball. It was concluded that subjects could not completely separate the initiation phase from the movement phase of the task but could significantly reduce the RT by focusing on the initiation portion of the task.

Abstract Adhesion between rubber and brass-coated steel cords is enhanced by using resins as adhesion promoters. Experiments were carried out using a squalene liquid rubber modeling approach to study the effect of resins on the chemistry of the vulcanization reaction. The formation of new intermediates during vulcanization and changes in chemical concentrations with reaction time was studied using Gel Permeation Chromatography (GPC) analysis of the reacted squalene mixtures. Also, the effect of presence of resins on the surface of sulfidized brass cords was studied by analyzing the adhesion layer's elemental composition using the Electron Dispersive X-ray Spectroscopy (EDX) and Secondary Ion Mass Spectrometry (SIMS) characterization techniques. The changes in surface morphology of the adhesion layer with reaction time was noted by taking micrographs using the Scanning Electron Microscopy (SEM) technique. In this paper, a new mechanism is proposed for the role of resins in the improvement of initial and aged adhesion performance between rubber and brass-coated steel tire cords.

AbstractWhen people answer the question “How many animals of each kind did Moses take on the Ark?”, they usually respond with “two,” although Moses does not appear in the biblical story of the Ark. We investigated this “Moses illusion” in a multiple-choice format and tested the influence of monetary incentives on the illusion’s strength. Thereby, we addressed the role of a cooperative communication context for the illusion’s emergence, as well as the role of participants’ motivation. In four experiments (total N = 914), we found that the Moses illusion persists in a multiple-choice format. As the multiple-choice format realizes a cooperative context in which the correct answer is always available, we exclude a cooperative context explanation for the illusion. Monetary incentives reduced the strength of the illusion. However, the reduction was numerically and statistically small. We thereby show that the illusion is not due to violations of cooperative communications, and not due to a lack of motivation. The multiple-choice approach will facilitate further research on the Moses illusion and the data provide additional evidence for the Moses illusion’s empirical robustness and constrain its theoretical explanations.
