Spastic dysphonia: A fluency disorder?

A case is presented for classifying spastic dysphonia, which usually is classified as a disorder of phonation, as a disorder of fluency—one that has a symptomatology and phenomenology, and possibly etiology, which is similar to stuttering. This case is based in part on a study that is reported in which listeners described speech associated with this condition as lacking in fluency. Theoretical, clinical, and research implications are discussed.     

Can fluency be interpreted as novelty? Retraining the interpretation of fluency in recognition memory

Stimuli that are processed fluently tend to be regarded as more familiar and are more likely to be classified as old on a recognition test compared with less fluent stimuli. Recently it was shown that the standard relationship between fluency and positive recognition judgments can be reversed if participants are trained that previously studied stimuli are associated with lower levels of fluency. Under such conditions, fluent stimuli are more likely to be classified as new on a recognition test (C. Unkelbach, 2006), which suggests that the interpretation of fluency is malleable and context dependent. Five experiments investigated the resilience of this reversed fluency effect. Using 2 different fluency manipulations, the finding of a reversed fluency effect after training was replicated. However, it was also found that the reversal depends on explicit feedback during training and is specific to the particular fluency manipulation used during training. Moreover, it was found that the reversal did not generalize to similar memory judgments. The balance of experimental results suggest that the standard interpretation of fluency as indicating higher levels of familiarity is quite stable and is resistant to reinterpretation.     

Is the fluency of language outputs related to individual differences in intelligence and executive function?

There has been little research on the fluency of language production and individual difference variables, such as intelligence and executive function. In this study, we report data from 106 participants who completed a battery of standardized cognitive tasks and a sentence production task. For the sentence production task, participants were presented with two objects and a verb and their task was to formulate a sentence. Four types of disfluency were examined: filled pauses (e.g. uh, um), unfilled pauses, repetitions, and repairs. Repetitions occur when the speaker suspends articulation and then repeats the previous word/phrase, and repairs occur when the speaker suspends articulation and then starts over with a different word/phrase. Hierarchical structural equation modeling revealed a significant relationship between repair disfluencies and inhibition. Conclusions focus on the role of individual differences in cognitive ability and their role in models and theories of language production.     

When does feeling of fluency matter?: how abstract and concrete thinking influence fluency effects

It has been widely documented that fluency (ease of information processing) increases positive evaluation. We proposed and demonstrated in three studies that this was not the case when people construed objects abstractly rather than concretely. Specifically, we found that priming people to think abstractly mitigated the effect of fluency on subsequent evaluative judgments (Studies 1 and 2). However, when feelings such as fluency were understood to be signals of value, fluency increased liking in people primed to think abstractly (Study 3). These results suggest that abstract thinking helps distinguish central decision inputs from less important incidental inputs, whereas concrete thinking does not make such a distinction. Thus, abstract thinking can augment or attenuate fluency effects, depending on whether fluency is considered important or incidental information, respectively.     

Does retrieval fluency contribute to the underconfidence-with-practice effect?

Judgments of learning (JOLs) made during multiple study-test trials underestimate increases in recall performance across those trials, an effect that has been dubbed the underconfidence-with-practice (UWP) effect. In 3 experiments, the authors examined the contribution of retrieval fluency to the UWP effect for immediate and delayed JOLs. The UWP effect was demonstrated with reliable underconfidence on Trial 2 occurring for both kinds of JOL. However, in contrast to a retrieval-fluency hypothesis, fine-grained analyses indicated that the reliance of JOLs on retrieval fluency contributed minimally to the UWP effect. Our discussion focuses on the status of the retrieval-fluency hypothesis for the UWP effect.     

Why do older adults have difficulty with semantic fluency?

Aging involves many cognitive declines, particularly in fluid intelligence, with relative maintenance of crystallized intelligence. This paradox is evident in the language domain: lexical retrieval becomes slower and less accurate, despite well preserved vocabularies. Verbal fluency assesses both crystallized and fluid aspects of language. Semantic fluency hypothetically reflects semantic knowledge, while letter fluency putatively reflects executive functioning, which would predict a greater impact of aging on the latter. However, the opposite is typically observed.

To investigate factors contributing to such asymmetries, we examined verbal fluency in 86 adults (30-89 years). Multiple regression analyses indicated that semantic fluency depends largely on lexical retrieval speed, as well as visualization strategies to support controlled retrieval, skills which may disproportionately decline with age. By contrast, letter fluency relies heavily on vocabulary knowledge, providing some protection against age-related declines. These findings contribute to our understanding of the mechanisms of typical age-related declines in word retrieval.     

Stuttering and fluency: Exclusive events or points on a continuum?

In recent years, several studies have been conducted in which the fluency of stutterers was compared with that of normal speakers. These investigations have been of two basic types, some involving objective measures of physiologic, aerodynamic, or acoustic features of the subjects' fluent speech signal, and others involving experiments performed in which listeners attempted to distinguish the fluency produced by stutterers from that generated by normal speakers. The body of literature pertaining to each of these two types of investigations is reviewed and interpreted. The interpretations offered are then developed in an effort to shed further light on both fluency and stuttering. Implications for further research, as well as for the evaluation, treatment, and post-therapy assessment of stutterers are drawn.     

What Is Music? Is There a Definitive Answer?

Philosophers frequently defend definitions by appealing to intuitions and contemporary folk classificatory norms. I raise methodological concerns that undermine some of these defenses. Focusing on Andrew Kania's recent definition of music, I argue that the way in which it has been developed leads to problems, and I show that a number of other definitions of interest to philosophers of art (and others) run into similar problems.

Is Phosphorus Hesperus?

It is argued that philosophers who adopt the perdurance theory of persistence and who subscribe to the principle of Unrestricted Mereological Composition (UMC) are in a position to regard “Phosphorus is Hesperus” as false.     

Is open-mindedness truth-conducive?

What makes an intellectual virtue a virtue? A straightforward and influential answer to this question has been given by virtue-reliabilists: a trait is a virtue only insofar as it is truth-conducive. In this paper I shall contend that recent arguments advanced by Jack Kwong in defence of the reliabilist view are good as far as they go, in that they advance the debate by usefully clarifying ways in how best to understand the nature of open-mindedness. But I shall argue that these considerations do not establish the desired conclusions that open-mindedness is truth-conducive. To establish these much stronger conclusions we would need an adequate reply to what I shall call Montmarquet’s objection. I argue that Linda Zagzebski’s reply to Montmarquet’s objection, to which Kwong defers, is inadequate. I conclude that it is contingent if open-mindedness is truth-conducive, and if a necessary tie to truth is what makes an intellectual virtue a virtue, then the status of open-mindedness as an intellectual virtue is jeopardised. We either need an adequate reliabilist response to Montmarquet’s objection, or else seek alternative accounts of what it is that makes a virtue a virtue. I conclude by briefly outlining some alternatives.

     

Is Mother Other?

Abstract

The discourse of maternality figures a contentious site for feminist theology. If figured in terms of a fecund womb, maternality risks reinscribing women in a masculine symbolic order of world-making that has long conflated women’s differences with motherhood, narrowly defined in terms of fecundity. After considering the ways identifying female sexual difference with motherhood reifies a masculine model of subjectivity, this paper turns to Lynne Huffer’s reading of feminist psychoanalyst Luce Irigaray to suggest that maternality has the potential to interrupt the self-same movement of masculine discourse and engender an ethical space of difference of and for the other. Examining Irigaray’s interweaving of maternality with pleasure to create space for women’s desires, this paper concludes that the ambiguity of desires through which maternality is constituted challenges the care-driven, natality-centered discourse of maternality itself. As a scene of unresolved desire between flesh and discourse, immanence and transcendence, self and other, maternality can be narrated to disrupt views of mother as origin that would otherwise return motherhood to a figure of sameness and to construct a possibility of desire for intersubjective becoming that is at once beyond narration and entirely concrete. Maternality thus presents desires unrecognizable within a prevailing symbolic framework in a way that bears witness to the disruptiveness of those desires and engenders radical alterity.     

Is philosophy progressive?

Any adequate attempt to discuss progressivity in philosophy should provide some explanation of why philosophy persistently honours the old and the false and deals with original texts in a way in which science does not. An attempt is made to answer this question by appealing to: (1) the aporetic character of philosophy; (2) the semantical solipsism of philosophy; (3) the subjectivity of philosophy, and; (4) poetical continuities in philosophy.
