Compensation for coarticulation reflects gesture perception, not spectral contrast

This article reports three experiments designed to explore the basis for speech perceivers' apparent compensations for coarticulation. In the first experiment, the stimuli were members of three /da/-to-/ga/ continua hybridized from natural speech. The monosyllables had originally been produced in disyllables /ada/ and /aga/ to make Continuum 1, /alda/ and /alga/ (Continuum 2), and /arda/ and /arga/ (Continuum 3). Members of the second and third continua were influenced by carryover coarticulation from the preceding /l/ or /r/ context. Listeners showed compensation for this carryover coarticulation in the absence of the precursor /al/ or /ar/ syllables. This rules out an account in which compensation for coarticulation reflects a spectral contrast effect exerted by a precursor syllable, as previously has been proposed by Lotto, Holt, and colleagues (e.g., Lotto, Kluender, & Holt, 1997; Lotto & Kluender, 1998). The second experiment showed an enhancing effect of the endpoint monosyllables in Experiment 1 on identifications of preceding natural hybrids along an /al/-to-/ar/ continuum. That is, coarticulatory /l/ and /r/ information in /da/ and /ga/ syllables led to increased judgments of /l/ and /r/, respectively, in the precursor /al/-to-/ar/ continuum members. This was opposite to the effect, in Experiment 3, of /da/ and /ga/ syllables on preceding tones synthesized to range in frequency from approximately the ending F3 of /ar/ to the ending F3 of /al/. The enhancing, not contrastive, effect in Experiment 2, juxtaposed to the contrastive effect in Experiment 3, further disconfirms the spectral contrast account of compensation for coarticulation. A review of the literature buttresses that conclusion and provides strong support for an account that invokes listeners' attention to information in speech for the occurrence of gestural overlap.     

Young infants’ perception of liquid coarticulatory influences on following stop consonants

Phonetic segments are coarticulated in speech. Accordingly, the articulatory and acoustic properties of the speech signal during the time frame traditionally identified with a given phoneme are highly context-sensitive. For example, due to carryover coarticulation, the front tongue-tip position for HI results in more fronted tongue-body contact for a /g/ preceded by /l/ than for a /g/ preceded by /r/. Perception by mature listeners shows a complementary sensitivity—when a synthetic /da/-/ga/ continuum is preceded by either /al/ or /ar/, adults hear more /g/s following HI rather than Irl. That is, some of the fronting information in the temporal domain of the stop is perceptually attributed to /l/ (Mann, 1980). We replicated this finding and extended it to a signaldetection test of discrimination with adults, using triads of disyllables. Three equidistant items from a /da/-/ga/ continuum were used preceded by /al/ and /ar/. In the identification test, adults had identified item ga5 as “ga”, and dal as “da”, following both /al/ and /ar/, whereas they identified the crucial item d/ga3 predominantly as “ga” after /al/ but as “da” after /ar/. In the discrimination test, they discriminated d/ga3 from dal preceded by /al/ but not /ar/; compatibly, they discriminated d/ga3 readily from ga5 preceded by /ar/ but poorly preceded by /al/. We obtained similar results with 4-month-old infants. Following habituation to either ald/ga3 or ard/ga3, infants heard either the corresponding ga5 or dal disyllable. As predicted, the infants discrimi-nated d/ga3 from dal following /al/ but not /ar/; conversely, they discriminated d/ga3 from ga5 following /ar/ but not /al/. The results suggest that prelinguistic infants disentangle consonant-consonant coarticulatory influences in speech in an adult-like fashion.

Three equidistant items from a /da/-/ga/ continuum were used preceded by /al/ and /ar/. In the identification test, adults had identified item ga5 as "ga,' and dal as "da,' following both /al/ and /ar/, whereas they identified the crucial item d/ga3 predominantly as "ga' after /al/ but as "da' after /ar/. In the discrimination test, they discriminated d/ga3 from da1 preceded by /al/ but not /ar/; compatibly, they discriminated d/ga3 readily from ga5 preceded by /ar/ but poorly preceded by /al/. We obtained similar results with 4-month-old infants. Following habituation to either ald/ga3 or ard/ga3, infants heard either the corresponding ga5 or da1 disyllable. As predicted, the infants discriminated d/ga3 from da1 following /al/ but not /ar/; conversely, they discriminated d/ga3 from ga5 following /ar/ but not /al/. The results suggest that prelinguistic infants disentangle consonant-consonant coarticulatory influences in speech in an adult-like fashion.     

The majority principle in Islamic legal and political thought1

This article studies the concepts of ijmā, al‐sawād al‐a am, jumhūr, al‐tarjī bi‐al‐kathra and legal maxims al‐qawaid al‐fiqhiyya at some length and relates them to the majority principle. These concepts represent a rich field of legal rules, principles and opinions, and the study has found that most—if not all—of them could strengthen the case for the legitimization of the majority principle in Islamic political thought and decision‐making processes. The article also considers Islamic political thought in relation to popular sovereignty, equality, popular consultation and the adoption of majority decisions by all the participants in political processes. While it is by no means conclusive, the article clearly favors the adoption of the majority principle—alongside other principles validated in Islam—in shūratic processes in an Islamic state.     

Perception of /r/ and /l/ in a stop cluster: evidence of cross-modal context effects

Experiments were conducted investigating unimodal and cross-modal phonetic context effects on /r/ and /l/ identifications to test a hypothesis that context effects arise in early auditory speech processing. Experiment 1 demonstrated an influence of a preceding bilabial stop consonant on the acoustic realization of /r/ and /l/ produced within the stop clusters /ibri/ and /ibli/. In Experiment 2, members of an acoustic /iri/ to /ili/ continuum were paired with an acoustic /ibi/. These dichotic tokens were associated with an increase in "l" identification relative to the /iri/ to /ili/ continuum. In Experiment 3, the /iri/ to /ili/ tokens were dubbed onto a video of a talker saying /ibi/. This condition was associated with a reliable perceptual shift relative to an auditory-only condition in which the /iri/ to /ili/ tokens were presented by themselves, ruling out an account of these context effects as arising during early auditory processing.     

Symbolism and allegory in the Qurān: Muhammad Asad's modernist translation

This paper will analyze Muhammad Asad's translation of the Qurān, which provides us with the means to explore the ‘mythic’ language of sacred text. Despite its modernist agenda, it is a coherent translation which brings into sharp focus a particular modernist discourse on the Qurān. The outcome of this approach is precisely in its style of picking and choosing meanings and interpretations which best suit the modernist project. The paper provides examples of this from the translation which has extensive footnote explanations. What distinguishes its approach from that of the classical commentators? Does the Qurān contain mythical or legendary accounts, and if so, what purpose do they serve? The paper focuses on these and other questions.     

Frequency of occurrence for units of phonemes, morae, and syllables appearing in a lexical corpus of a Japanese newspaper.

On the basis of the lexical corpus created by Amano and Kondo (2000), using the Asahi newspaper, the present study provides frequencies of occurrence for units of Japanese phonemes, morae, and syllables. Among the five vowels, /a/ (23.42%), /i/ (21.54%), /u/ (23.47%), and /o/ (20.63%) showed similar frequency rates, whereas /e/ (10.94%) was less frequent. Among the 12 consonants, /k/ (17.24%), /t/ (15.53%), and /r/ (13.11%) were used often, whereas /p/ (0.60%) and /b/ (2.43%) appeared far less frequently. Among the contracted sounds, /sj/ (36.44%) showed the highest frequency, whereas /mj/ (0.27%) rarely appeared. Among the five long vowels, /aR/ (34.4%) was used most frequently, whereas /uR/ (12.11%) was not used so often. The special sound /N/ appeared very frequently in Japanese. The syllable combination /k/+V+/N/ (19.91%) appeared most frequently among syllabic combinations with the nasal /N/. The geminate (or voiceless obstruent) /Q/, when placed before the four consonants /p/, /t/, /k/, and /s/, appeared 98.87% of the time, but the remaining 1.13% did not follow the definition. The special sounds /R/, /N/, and /Q/ seem to appear very frequently in Japanese, suggesting that they are not special in terms of frequency counts. The present study further calculated frequencies for the 33 newly and officially listed morae/syllables, which are used particularly for describing alphabetic loanwords. In addition, the top 20 bi-mora frequency combinations are reported.

Prophetic models in Islamic and Christian spirituality in the thought of Ibn Arabī and Meister Eckhart

A comparative study of Moses, Jesus and Muhammad in Christianity and Islam reveals common background, basic similarities, and differences. Ibn Arabī (d. 1240) and Meister Eckhart (d. 1327) regard Moses and Jesus not only as prophetic models but also as mystical examples for the Mūsāwī type of saints and ‘Jesus‐like’ (‘īsāwī) saints in both traditions. However, the two experts understandably differ with regard to the divine nature of Jesus. Eckhart considers Christ as the image of God (imago Dei), ‘the Only‐Begotten Son of God’, while Ibn Arabī perceives Jesus as having both a human nature (nāsūt) and a divine nature (lāhūt). Eckhart sees Jesus as the best model, but Ibn Arabī sees the best model as Muhammad. Eckhart regards Jesus as the source of existence, whereas Ibn Arabī perceives Muhammad as the source of the chain of prophecy and sainthood, wihc derives from the Muhammadan reality (aqīqa Muammadiyya).     

A versatile Mathal: ‘the man who hired laborers’

The parable of ‘The man who hired laborers’ is found in the adīth literature of Islam, in the Gospel of Matthew and in the Rabbinic literature of Judaism. This article focuses mainly on how the adīth texts use the parable, describing themes, rhetorical devices and narrative patterns of fourteen variant readings. Then the Jewish and Christian examples are compared with the Islamic ones, showing both the variety of themes to be found and the similarity of the common parabolic structure.     

The notion of necessary being in Fakhr al‐Dīn al‐Rāzī's philosophical theology

The notion of Necessary Being (wājib al‐wujūd) is so significant in Islamic intellectual tradition that it plays a major role in every single system of the tradition. We can see this very clearly in both Islamic philosophy and theology, where Necessary Being is placed in relation to cosmogony and cosmology. This article discusses the function of Necessary Being in the philosophical theology of Fakhr al‐Dīn al‐Rāzī in which Necessary Being is regarded as the axis mundo of the system. An examination of his works, especially Al‐mua al and Al‐tafsīr al‐kabīr, demonstrates that Necessary Being serves as the source of cosmogony, the principle of cosmology, the source of valuation and moral judgment, and the object of rituals.     

Semantic distinctions and memory for complex sentences

This investigation studied what people remember in recalling complex sentences, whether it is certain semantic distinctions or merely transformational markers. After short intervals 24 subjects tried to recall sentences of six kinds which formed paraphrase sets: S₁ before S₂, S₁ and then S₂, After S₁ S₂, S₂ after S₁, S₂ but first S₁, and Before S₂ S₁. (S₁ and S₂ denote first and second clauses in temporal, not linguistic, order.) Subjects remembered the underlying sense of sentences with S₁-S₂ clause ordering better than those with S₂-S₁ clause ordering, regardless of transformational complexity. Subjects also showed a response bias, hence better verbatim recall, for sentences with subordinate clause second and for sentences with S₁-S₂ clause ordering. Sentence confusions indicated that subjects remembered three semantic distinctions: the temporal order, order of mention, and main-subordinate relation of the two described events. A theory of memory for marked and unmarked semantic distinctions was used to account for the results.     

The effects of experimental variables on the perception of American English /r/ and /l/ by Japanese listeners.

The effects of variations in response categories, subjects' perception of natural speech, and stimulus range on the identification of American English /r/ and /l/ by native speakers of Japanese were investigated. Three experiments using a synthesized /rait/-/lait/ series showed that all these variables affected identification and discrimination performance by Japanese subjects. Furthermore, some of the perceptual characteristics of /r/ and /l/ for Japanese listeners were clarified: (1) Japanese listeners identified some of the stimuli of the series as /w/. (2) A positive correlation between the perception of synthesized stimuli and naturally spoken stimuli was found. Japanese listeners who were able to easily identify naturally spoken stimuli perceived the synthetic series categorically but still perceived a /w/ category on the series. (3) The stimulus range showed a striking effect on identification consistency; identification of /r/ and /l/ was strongly affected by the stimulus range, the /w/ identification less so. This indicates that Japanese listeners tend to make relative judgments between /r/ and /l/.

On the nature and message of the Lotus Sūtra in the light of early Buddhism and Buddhist scholarship (towards the beginnings of Mahāyāna)

The aim of this paper is to compare the contents of the Lotus Sūtra and the style of presentation of its message with the thrust of the Buddha's teachings as they are preserved in the early Buddhist sources, particularly the Sutta Piaka of the Pāli Canon, and also in the Pāli commentarial literature. In the process it attempts to identify in the early sources the precedents of some of the bold statements in the Lotus Sūtra which appear as complete innovations, but may be elaborations of elements contained in Pāli sources in germinal form. Despite the difference in style, language and mythological imagery, the conclusion is that both the Sutta Piaka and the Lotus Sūtra express in their respective manners the true spirit of the Buddhist message. Attention is drawn also to the striking parallels between the Buddhist picture of the multiple universe and modern cosmological theories.     

The McGurk effect in infants

In the McGurk effect, perceptual identification of auditory speech syllables is influenced by simultaneous presentation of discrepant visible speech syllables. This effect has been found in subjects of different ages and with various native language backgrounds. But no McGurk tests have been conducted with prelinguistic infants. In the present series of experiments, 5-month-old English-exposed infants were tested for the McGurk effect. Infants were first gaze-habituated to an audiovisual /va/. Two different dishabituation stimuli were then presented: audio /ba/-visual /va/ (perceived by adults as /va/), and audio /da/-visual /va/ (perceived by adults as /da/). The infants showed generalization from the audiovisual /va/ to the audio /ba/-visual /va/ stimulus but not to the audio /da/-visual /va/ stimulus. Follow-up experiments revealed that these generalization differences were not due to a general preference for the audio /da/-visual /va/ stimulus or to the auditory similarity of /ba/ to /va/ relative to /da/. These results suggest that the infants were visually influenced in the same way as Englishspeaking adults are visually influenced.     

Unconscious forces: a survey of some concepts in Indian philosophy

In this article, I examine some traditional Indian conceptions of unconscious mental activity. There are concepts in the Indian philosophical tradition, notably saskāras and vāsanās, which can be taken to refer to unconscious mental states and dispositions. My discussion, which is essentially philosophical by nature, is loosely based on the English philosopher C.D. Broad's distinctions concerning the unconscious. Saskāras, which are interpreted realistically in Indian tradition, may manifest themselves as what I (and Broad) call relatively unconscious states. Evidence for this interpretation can be found in discussions concerning the nature of dream state and the supernatural powers of yogis in Indian tradition. It is interesting to try to view the retributive system of karma as an absolutely unconscious system, but this is not a plausible interpretation of the Indian view of karma.

‘Aloneness’ and the problem of realism in classical Sākhya and yoga

The concept of kaivalya (literally, ‘aloneness’) is of crucial importance to the systems of classical Indian philosophy known as Sākhya and Yoga. Indeed, kaivalya is the supreme soteriological goal to which these systems are directed. Various statements concerning this final goal appear in the classical texts—namely, the Sākhyakārikā and Yogasūtra—and yet there is no consensus within modern scholarship about how the concept is to be interpreted. More specifically, there appears to be a great deal of confusion over the implications of kaivalya for the existence of the empirical world. In this article I discuss the principal difficulties encountered by existing interpretations of kaivalya, and propose that these difficulties result from an unwarranted assumption that Sākhya and Yoga take a realist view with regard to the empirical world. I further propose that these difficulties can, in large part, be overcome when the assumption of realism is set aside.     

Waiting

Many people have heard of the sacred sound Aum, but do we really understand what it means or what it is? This article answers that question by examining the original text in which the sacred syllable of Aum is introduced. The three letters that make up the sound Aum each represents a corresponding psychological state. Waking, dreaming, and dreamless sleep are the three main states of consciousness explored in the Mā ūkya Upaniad, a small section contained within the larger Hindu text known as the Upaniads. Some of these texts date back to around the second millennium b.c.e. What can these ancient explorations of human consciousness teach us today and how do they relate to modern depth psychology? The shortest of the Upaniads, the Mā ūkya Upaniad, may be said to hold some of the most profound psychological reflections in all of Indian religious philosophy. In addition to these three states of being, the elusive fourth state, known as Turīya, is also explored in relation to the sacred syllable Aum. This article integrates the commentaries of various Indian gurus with a perspective from analytical psychology. The sounds comprising Aum are explored symbolically and in terms of their psychological meaning, and the psychological role and function of spiritual practices, both East and West, are considered.
