Spectral information in nonspeech contexts influences children’s categorization of ambiguous speech sounds

For both adults and children, acoustic context plays an important role in speech perception. For adults, both speech and nonspeech acoustic contexts influence perception of subsequent speech items, consistent with the argument that effects of context are due to domain-general auditory processes. However, prior research examining the effects of context on children’s speech perception have focused on speech contexts; nonspeech contexts have not been explored previously. To better understand the developmental progression of children’s use of contexts in speech perception and the mechanisms underlying that development, we created a novel experimental paradigm testing 5-year-old children’s speech perception in several acoustic contexts. The results demonstrated that nonspeech context influences children’s speech perception, consistent with claims that context effects arise from general auditory system properties rather than speech-specific mechanisms. This supports theoretical accounts of language development suggesting that domain-general processes play a role across the lifespan.     

Perceptual-Motor Contributions to Static and Dynamic Balance Control in Children

The authors addressed balance control in children from the perspective of skill development and examined the relationship between specific perceptual and motor skills and static and dynamic balance performance. Fifty 11- to 13-year-old children performed a series of 1-legged balance tasks while standing on a force platform. Postural control was reflected in the maximum displacement of the center of mass in anterior-posterior and mediolateral directions. Simple visual, discrimination, and choice reaction times; sustained attention; visuomotor coordination; kinesthesis; and depth perception were also assessed in a series of perceptual and motor tests. The correlation analysis revealed that balancing under static conditions was strongly associated with the ability to perceive and process visual information, which is important for feedback-based control of balance. On the other hand, when greater task demands were imposed on the system under dynamic balancing conditions, the ability to respond to the destabilizing hip abductions-adductions in order to maintain equilibrium was associated with motor response speed, suggesting the use of a descending, feedforward control strategy. Therefore, like adults, 11- to 13-year-old children have the ability to select varying balance strategies (feedback, feedforward, or both), depending on the constraints of a particular task.     

Whiteheadian Societies and Peirce's Law of Mind: Actuality and Potentiality in the Cosmic Process

Abstract

A more suitable philosophical position to counter the claims of scientific materialism re the nature of physical reality can possibly be found in combining the metaphysics of A.N. Whitehead and C.S. Peirce. Peirce postulated a habit-forming tendency or inbuilt potentiality of the cosmic process as a whole to move over time toward ever greater organization and more complex structure. But he is vague on how “the law of the mind” applies to nature below the level of human self-awareness. Whitehead's notion of actual entities (momentary self-constituting subjects of experience) as the “final real things of which the world is made up” logically allows for some primitive form of subjectivity with the requisite potentiality for habit-formation at all levels of existence and activity within nature. In addition, Whitehead's notion of structured societies made up of subsocieties with a “regnant” subsociety seems philosophically to justify the new emphasis on bottom-up rather than top-down causation in the emergence of more complex levels of existence and activity within the life-sciences.     

The im-possibility of secular critique: The future of religion's memory

The legacy of secular critique, with its Greek, Christian, Kantian, modernist traces, constitutes an aporetic law (or contradiction). That law is this: a critical legacy, if it is critical, can affirm and sustain itself only by trying to separate it from itself (from the very crisis that it is). The legacy or history of ‘religion’ is always a history of such critique. Such a legacy always anticipates critiquing itself, its memory (of whatever kind – racist, sexist, colonialist, nationalist). Such a legacy of critique is always a legacy of crisis. However, the crisis of such a legacy cannot be resolved, because critique, as kairos/krisis (critical/decisive moment), can admit of no resolution. Yet the (secular) history of religion, if it is ever historical, can only be a history of such aporetic critique. Such an aporetic critique will be the heritage of religion's im-possible ¹ ?1. I write the word impossible/impossibility with and without a hyphen. When I hyphenate im-possible, I do so to remain true to Derrida's use of it. The im-possible is irreducible to either possibility or impossibility. Sometimes Derrida also writes the word without hyphenating it, but he still implies such irreducibility. future. It is an im-possible future because it will always be a promise, a promise to separate it from itself, a promise that will remain always deferred, always to come. Today, the promise of this secular critique is (in) democracy with its sovereign ‘decisive’ politics. We can no longer simply critique the (future) legacy of religion, understood this way. To do so is to fulfil that legacy's own messianic wish. This is the aporetic limit of secular critique. To think at the limits of the legacy of the critique of religion is to think the very question of the (secular) history of ‘religion’ and its others, that is, ‘religions’.     

Sound symbolic naming of novel objects is a graded function

Although linguistic traditions of the last century assumed that there is no link between sound and meaning (i.e., arbitrariness), recent research has established a nonarbitrary relation between sound and meaning (i.e., sound symbolism). For example, some sounds (e.g., /u/ as in took) suggest bigness whereas others (e.g., /i/ as in tiny) suggest smallness. We tested whether sound symbolism only marks contrasts (e.g., small versus big things) or whether it marks object properties in a graded manner (e.g., small, medium, and large things). In two experiments, participants viewed novel objects (i.e., greebles) of varying size and chose the most appropriate name for each object from a list of visually or auditorily presented nonwords that varied incrementally in the number of “large” and “small” phonemes. For instance, “wodolo” contains all large-sounding phonemes, whereas “kitete” contains all small-sounding phonemes. Participants' choices revealed a graded relationship between sound and size: The size of the object linearly predicted the number of large-sounding phonemes in its preferred name. That is, small, medium, and large objects elicited names with increasing numbers of large-sounding phonemes. The results are discussed in relation to cross-modal processing, gesture, and vocal pitch.     

On the logic of psychoanalytic theory

Psychoanalytic theory shows some specific features and problems. It exists in a number of variations, according to different schools as well as cultural and subcultural conditions, with different understandings even of core concepts. Instead of producing definite knowledge, results remain uncertain. They vary in use and imply a permanent reworking of ideas and conceptions. This is the effect of the kind of theory psychoanalysis has to use. Since psychodynamics are a special kind of heterogeneous, changing, always different, emergent-in a word, autopoietic-reality, psychoanalysis cannot use the methods of a denotative theory (algorithmic reduction leading to strictly defined and formulated calculations) but has to use connotative theories. Connotative theories use open concepts which provide an active and flexible access to autopoietic reality. They are able to cope with the difference between singularities as well as with the distance between general logic and empirical reality. Problems tied to this possibility are structural fuzziness, a dependence on forms of use, multiple paradigms and difficulties in legitimation and balance of theories. This causes problems of institutionalisation. These problems are not a sign of immaturity but the normal way in which connotative theories appear and develop. They can therefore not be eliminated but only be treated in a better way.     

“Seeing Rain”: Integrating phenomenological and Bayesian predictive coding approaches to visual hallucinations and self-disturbances (Ichstörungen) in schizophrenia

We present a schizophrenia patient who reports “seeing rain” with attendant somatosensory features which separate him from his surroundings. Because visual/multimodal hallucinations are understudied in schizophrenia, we examine a case history to determine the role of these hallucinations in self-disturbances (Ichstörungen). Developed by the early Heidelberg School, self-disturbances comprise two components: 1. The self experiences its own automatic processing as alien to self in a split-off, “doubled-I.” 2. In “I-paralysis,” the disruption to automatic processing is now outside the self in omnipotent agents. Self-disturbances (as indicated by visual/multimodal hallucinations) involve impairment in the ability to predict moment-to-moment experiences in the ongoing perception-action cycle. The phenomenological approach to subjective experience of self-disturbances complements efforts to model psychosis using the computational framework of hierarchical predictive coding. We conclude that self-disturbances play an adaptive, compensatory role following the uncoupling of perception and action, and possibly, other low-level perceptual anomalies.     

Linguistic and emotional-valence characteristics of reading passages for clinical use and research

PurposeFluency assessment in people who stutter (PWS) includes reading aloud passages. There is little information on properties of these passages that may affect reading performance: emotional valance, arousal, word familiarity and frequency and passage-readability. Our first goal was to present an extensive examination of these factors in three commonly used (“traditional”) passages. The second goal was to compare a traditional passage to a new passage, designed to minimize the impact of these properties.MethodsContent words were rated (129 participants) on arousal, valence and familiarity. Other linguistic features were analyzed based on available datasets. This information was used to assess traditional passages, and to construct a new well-balanced passage, made of neutral, low-arousal and highly-familiar words. Readability for all passages was tested using formula-based and CLOZE tests (31 participants). Finally, 26 PWS were evaluated on fluency comparing the commonly used “Rainbow” passage with the novel one.ResultsThe three traditional passages contain a share of emotionally valenced (22-34%), high arousal (15-18%), lower familiarity (6-8%) and polysyllabic (5-9%) content words. Readability was highest for the novel passage (on formula-based scales). Average disfluencies percent for the Rainbow and our novel passage were not significantly different. Yet half of the individuals in this sample showed a large difference between the two passages.ConclusionWe provide detailed information on potential sources of variance using the traditional passages. Knowledge about these characteristics can inform clinical practice (and research). We suggest a combined procedure, using more than one passage to assess stuttering in individual cases.     

Pavlovian george windholz (1931–2002): An exemplar of scholarly “observation and observation” and a critical contributor to psychology,and hence to behavioral neuroscience

Although most members of the Pavlovian Society properly focus their efforts on empirical research, the scholarly, critical conceptual contributions of some individuals are also relevant to progress in psychology and behavioral neuroscience. This paper discusses the contributions of the late George Windholz (often in collaboration with Peter Lamal) as: (a) a historian of Pavlov’s life, and work; (b) an analyst of priority issues in psychology as a science; (c) a refuter of myths perpetrated by psychology texts. These contributions provide an example of the scholarly form of the motto “observation and observation,” where the data used to test hypotheses comprise original documents (often in languages other than English) examined by the historian’s critical eye.
