Continuous mapping from sound to meaning in spoken-language comprehension: immediate effects of verb-based thematic constraints

The authors used 2 "visual-world" eye-tracking experiments to examine lexical access using Dutch constructions in which the verb did or did not place semantic constraints on its subsequent subject noun phrase. In Experiment 1, fixations to the picture of a cohort competitor (overlapping with the onset of the referent's name, the subject) did not differ from fixations to a distractor in the constraining-verb condition. In Experiment 2, cross-splicing introduced phonetic information that temporarily biased the input toward the cohort competitor. Fixations to the cohort competitor temporarily increased in both the neutral and constraining conditions. These results favor models in which mapping from the input onto meaning is continuous over models in which contextual effects follow access of an initial form-based competitor set.     

On the discovery of novel wordlike units from utterances: an artificial-language study with implications for native-language acquisition.

In 4 experiments, adults were familiarized with utterances from an artificial language. Short utterances occurred both in isolation and as part of a longer utterance, either at the edge or in the middle of the longer utterance. After familiarization, participants' recognition memory for fragments of the long utterance was tested. Recognition was greatest for the remainder of the longer utterance after extraction of the short utterance, but only when the short utterance was located at the edge of the long utterance. These results support the incremental distributional regularity optimization (INCDROP) model of speech segmentation and word discovery, which asserts that people segment utterances into familiar and new wordlike units in such a way as to minimize the burden of processing new units. INCDROP suggests that segmentation and word discovery during native-language acquisition may be driven by recognition of familiar units from the start, with no need for transient bootstrapping mechanisms.     

The quest for the good life in Rousseau's Emile: an assessment

Rousseau's Emile has attracted an avalanche of critical responses. His theme of negative education, or as he defines it, well-regulated freedom, has been denounced as outright manipulation in disguise, which instead of respecting the child's autonomy and dignity, places him at the whim of the teacher's machinations and stratagems. His recommendation that the child's imagination be curtailed (that he may not acquire desires which cannot be satisfied) is widely held to militate against one of the most cherished goals of education: the fostering of the natural curiosity of the child. Rousseau is also accused of professing an ideology of childhood which ignores the real needs of children. In the sterilized environment which Rousseau proposes for the growing child, affection, praise and approval, are some of the sacrifices made to this ideology. Furthermore, his views on women are considered degrading, outrageous and blatantly sexist.Yet despite the myriad criticisms leveled against his work, Rousseau's Emile highlights one of the most exacting challenges for education — how to educate the child without alienating him. Rousseau connects this issue with the larger problem of alienation: namely, that experienced by man within the modern social order. Rousseau's views anticipate the contemporary debate between virtue-based and deontological ethics.The purpose of this paper is (i) to describe Rousseau's diagnosis of the problem of alienation as it arises in the various spheres of human life, paying special attention to the moral domain, and (ii) to assess the solutions he offers to the problem of alienation. These solutions are based on a conception of the good life which, I argue, is unacceptable. I also argue that this conception dissipates one form of alienation only at the expense of creating another.The paper begins by tracing the changes which the concept of alienation has undergone, and consequently I draw a distinction between two kinds of alienation — conscious and unconscious. I demonstrate that even if Rousseau is successful in offering a remedy for conscious alienation, this very remedy itself gives rise to unconscious alienation.     

The role of prosodic boundaries in the resolution of lexical embedding in speech comprehension

Participants' eye movements were monitored as they heard sentences and saw four pictured objects on a computer screen. Participants were instructed to click on the object mentioned in the sentence. There were more transitory fixations to pictures representing monosyllabic words (e.g. ham) when the first syllable of the target word (e.g. hamster) had been replaced by a recording of the monosyllabic word than when it came from a different recording of the target word. This demonstrates that a phonemically identical sequence can contain cues that modulate its lexical interpretation. This effect was governed by the duration of the sequence, rather than by its origin (i.e. which type of word it came from). The longer the sequence, the more monosyllabic-word interpretations it generated. We argue that cues to lexical-embedding disambiguation, such as segmental lengthening, result from the realization of a prosodic boundary that often but not always follows monosyllabic words, and that lexical candidates whose word boundaries are aligned with prosodic boundaries are favored in the word-recognition process.     

Time course of frequency effects in spoken-word recognition: evidence from eye movements

In two experiments, eye movements were monitored as participants followed spoken instructions to click on and move pictures with a computer mouse. In Experiment 1, a referent picture (e.g., the picture of a bench) was presented along with three pictures, two of which had names that shared the same initial phonemes as the name of the referent (e.g., bed and bell). Participants were more likely to fixate the picture with the higher frequency name (bed) than the picture with the lower frequency name (bell). In Experiment 2, referent pictures were presented with three unrelated distractors. Fixation latencies to referents with high-frequency names were shorter than those to referents with low-frequency names. The proportion of fixations to the referents and distractors were analyzed in 33-ms time slices to provide fine-grained information about the time course of frequency effects. These analyses established that frequency affects the earliest moments of lexical access and rule out a late-acting, decision-bias locus for frequency. Simulations using models in which frequency operates on resting-activation levels, on connection strengths, and as a postactivation decision bias provided further constraints on the locus of frequency effects.     

Effects of prosodically modulated sub-phonetic variation on lexical competition

Eye movements were monitored as participants followed spoken instructions to manipulate one of four objects pictured on a computer screen. Target words occurred in utterance-medial (e.g., Put the cap next to the square) or utterance-final position (e.g., Now click on the cap). Displays consisted of the target picture (e.g., a cap), a monosyllabic competitor picture (e.g., a cat), a polysyllabic competitor picture (e.g., a captain) and a distractor (e.g., a beaker). The relative proportion of fixations to the two types of competitor pictures changed as a function of the position of the target word in the utterance, demonstrating that lexical competition is modulated by prosodically conditioned phonetic variation.     

Talker adaptation in speech perception: adjusting the signal or the representations?

Past research has established that listeners can accommodate a wide range of talkers in understanding language. How this adjustment operates, however, is a matter of debate. Here, listeners were exposed to spoken words from a speaker of an American English dialect in which the vowel /ae/ is raised before /g/, but not before /k/. Results from two experiments showed that listeners' identification of /k/-final words like back (which are unaffected by the dialect) was facilitated by prior exposure to their dialect-affected /g/-final counterparts, e.g., bag. This facilitation occurred because the competition between interpretations, e.g., bag or back, while hearing the initial portion of the input [bae], was mitigated by the reduced probability for the input to correspond to bag as produced by this talker. Thus, adaptation to an accent is not just a matter of adjusting the speech signal as it is being heard; adaptation involves dynamic adjustment of the representations stored in the lexicon, according to the characteristics of the speaker or the context.     

Negotiation as a form of persuasion: arguments in first offers

In this article we examined aspects of negotiation within a persuasion framework. Specifically, we investigated how the provision of arguments that justified the first offer in a negotiation affected the behavior of the parties, namely, how it influenced counteroffers and settlement prices. In a series of 4 experiments and 2 pilot studies, we demonstrated that when the generation of counterarguments was easy, negotiators who did not add arguments to their first offers achieved superior results compared with negotiators who used arguments to justify their first offer. We hypothesized and provided evidence that adding arguments to a first offer was likely to cause the responding party to search for counterarguments, and this, in turn, led him or her to present counteroffers that were further away from the first offer.     

Eastern Jews vs. Western Jews: the Ahad Ha’am–Herzl dispute and its cultural and social implications

The conflict between Herzl and Ahad Ha’am encapsulated the cultural divide that separated the two, as well as it reflected the political and ideological rift separating East from West. The Eastern block wished Zionism to maintain strong ties to a sense of Jewish continuity (if not necessarily to traditional Jewish practice). The Western one was more cosmopolitan and assimilationist in its bent. From the first Zionist Congress onward, Ahad Ha’am assumed the role of Herzl’s chief opponent. At first, he was a voice crying in the wilderness, but within seven years, he headed a united front whose members sought to remove Herzl or at least force him into a minority. The point of no return was reached in a clash known as the “Alteneuland Affair,” whose personal side was as strong as its other aspects, if not more so. For after this episode concluded with this defeat and Herzl’s victory, Ahad Ha’am bowed out of all active Zionist political life.
