Stuttering and anxiety: The difference between stutterers and nonstutterers in verbal apprehension and physiologic arousal during the anticipation of speech and non-speech tasks

To test if stressful anticipation of speech situations is a factor in eliciting stuttering behavior, the difference between 24 stutterers and 24 nonstutterers in verbal apprehension and physiologic activity was studied before and during speech tasks (reading and conversation), and nonspeech tasks (motor and intelligence task).Results indicate that the difference between stutterers and nonstutterers mainly were restricted to anxiety ratings assessed after each task. Heart rate, vasomotor responses, and electrodermal activity recorded before and during speech tasks were higher compared with the physiologic activity before and during nonspeech tasks but, unexpectedly, this was also the case for nonstutterers. It is concluded that stuttering is not elicited by anxiety.     

Counterfactuals and Context-Sensitivity

It is commonly agreed that when evaluating the validity of an argument involving context-sensitive expressions, the context should be held fixed. In their 2008 essay “Counterfactuals and Context,” Brogaard and Salerno argue further that context should be held fixed when evaluating an argument involving counterfactuals for validity, since, as many will agree, counterfactuals are context-sensitive. In the present paper, it will however be argued that Brogaard and Salerno fail to distinguish between two different roles that context plays in determining the meaning of a given counterfactual. If they were fully aware of the distinction between these two roles played by context, they might propose a contextualist approach to counterfactuals, as has been developed by Ichikawa in his 2011 paper “Quantifiers, Knowledge, and Counterfactuals.”     

Performance of retarded adolescents and nonretarded children on one- and two-bit logical problems

Groups of adolescents of retarded and borderline intelligence, ranging in IQ from 44 to 80 and in mean MA (mental age) from 8 to 12 yr, and groups of nonretarded children ranging in mean MA from 6 to 12 yr, were given logical problem solving tasks. In the nonretarded groups, on a one-bit problem only the kindergarten children (mean MA = 6 yr) failed to perform above chance, and were not tested further. On a two-bit problem, only the first graders (mean MA = 7 yr) failed to perform above chance.Conversely, in the low IQ groups, only the borderline group (mean MA = 12 yr) performed reliably above chance on the one-bit problem, and none performed above chance on the two-bit problem. There is a profound deficiency in low IQ individuals on certain tasks requiring logic and foresight, and MA markedly over-estimates their performance relative to the performance of nonretarded individuals.     

The relationship between expressed social fears and assertiveness and its treatment implications

Behavior therapists have speculated about the relationship between social fears or social anxieties and lack of assertive behavior. Wolpe (1958) perhaps most clearly suggested such a relationship. “If he [the patient] has been ineffectual in such situations—unable, for instance, to return a faulty garment—I explain how unadaptive fears are at the bottom of this ineffectualness. … p. 116.” Wolpe further assumed that engaging in assertive behavior reciprocally inhibited fear in these same social situations and that assertive responses can be programmed for use in overcoming these fears.In later writings (Wolpe. 1969; Wolpe and Lazarus, 1966) Wolpe seems to have broadened his position concerning the cause of non-assertive behavior. Specifically, he now allows that an individual also may be non-assertive, “… not because of anxiety but because they have never had the opportunity of acquiring the necessary habits. p. 40” (Wolpe and Lazarus, 1966). For these individuals direct efforts in assertive training such as behavior rehearsal, operant conditioning or direct instruction are in order. For these individuals whose lack of assertiveness is due to a ‘phobic reaction’ or strong extrinsic fears, systematic desensitization is recommended in addition to assertive training.Despite this apparent change in position, the intuitively appealing notion that the more socially fearful an individual is the more non-assertive he is likely to be has not received the empirical attention it deserves. Rathus (1973) seems to have provided some indirect evidence pertaining to the relationship between social fears and assertiveness. In the context of evaluating the efficacy of an assertive training method he administered both the 100-item Temple Fear Survey Inventory (TFSI) (Braun and Reynolds, 1969) and the Rathus Assertiveness Schedule (RAS) (Rathus, 1973) to groups of female students receiving either assertive training, a placebo treatment or no treatment. He found that at post-test the assertive training group scored significantly higher than either the placebo or no treatment groups on the RAS and that there were no significant differences in post-test Full Scale TSFI Scores. Fear of Social Criticism Factor Scores or Fear of Social Incompetence Factor Scores although in each case the mean changes toward less fear were greater for the group receiving assertive training. This finding gives little support to the reciprocal relationship between social fears and assertiveness. What is needed is a direct determination of the degree to which social fears and assertiveness are related in a sizeable sample of subjects.     

Kant and German idealisms

This paper considers whether Hegel's master/slave dialectic in the Phenomenology of Spirit should be considered as a refutation of solipsism. It focuses on a recent and detailed attempt to argue for this sort of reading that has been proposed by Frederick Beiser – but it argues that this reading is unconvincing, both in the historical motivations given for it in the work of Jacobi and Fichte, and as an interpretation of the text itself. An alternative reading of the dialectic is proposed, where it is argued that the central problem Hegel is concerned with is not solipsism, but the sociality of freedom.     

Exposure and response prevention of morbid ruminations and compulsive avoidance

Two patients with morbid ruminations and compulsive avoidance behavior were independently treated by the authors with exposure and response prevention strategies. The patients were quite different with respect to age (23 vs 58), occupational status (student vs civil servant) and length of disorder (2 vs 40 years), although their disorders were quite similar. The present report describes the patients and treatment procedures and reports on dramatic behavioral changes that occurred within brief time periods.     

The history of Russian psychoanalysis and the problem of its periodisation

The formation and spread of the psychoanalytic teaching of Sigmund Freud and his followers is one of the most significant events in the life of the spirit in the twentieth century. The recognition of this as an historical fact--irrespective of its relation to Freud and his ideas--assumes of course and need to gain a proper understanding and appropriate interpretation of psychoanalysis in all its dimensions. Generally speaking, the history of psychoanalysis and the psychoanalytic movement has been researched quite fully, although for a variety of reasons and circumstances there are a number of gaps in it. Perhaps the most important of these is the history of Russian psychoanalysis, which has developed within a country where, at the beginning of the century, Freud's works were translated and published in a most effective and representative way, and where psychoanalytic ideas drew a response both from specialists and among the public at large, although in content and inclination the Russian mentality did not at heart suit a psychoanalytical treatment of man and his culture.     

Martin Heidegger and Russian Symbolist Philosophy

In this paper Russian Symbolist philosophy is represented primarily by Viacheslav Ivanov (1866--1949), but its conclusions are intended to be valid for other philosophers we classify as Symbolist, including Nikolai Berdiaev and S. L. Frank. It is posited that, by comparing Ivanov's cosmology, aesthetics, and anthropology to those of Martin Heidegger, one can reconceive of Symbolist philosophy as an existential hermeneutic. This, it is claimed, can help to identify a common basis among the Symbolist philosophers, and also to place Russian thought in the context of modern European philosophy and vice versa.     

Motor perseverative behavior in adult stutterers and nonstutterers

The performances of 22 adult stutterers and 22 adult nonstutterers on motor tasks requiring the graphic reproduction of a sequence of alternating figures following the production of a series of nonalternating figures were studied. The finding that there were no differences in the performance of the two groups on the alternating motor tasks was interpreted as challenging the validity of previous observations that motor perseverative behavior exists in stutterers and is indicative of a central neurological deficit in that population.     

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.     

Itinerant surfaces with spin-orbit couplings,correlations and external magnetic fields: exact results

We analyze, in exact terms, multiband 2D itinerant correlated fermionic systems with many-body spin-orbit interactions, and in-plane external magnetic fields. Even if such systems with broad applicability in leading technologies are non-integrable, we set up an exact solution procedure for them, which is described in details. Casting the Hamiltonian in positive semidefinite form, the technique leads to the ground state, and also characterises the low lying excitation spectrum.     

Language and speech recovery in a case of viral encephalitis

The speech and language recovery course of a 47-year-old man with viral encephalitis is described. Over a 3-month period, the patient was evaluated six times using the same selected battery of tests. Results show that viral encephalitis can deleteriously affect communicative performance and that improvement in medical status is accompanied by rapid and dramatic gains on most standard speech and language measures. For this case changes appeared related to improved auditory attention and retention, increased efficiency in word retrieval, and improved mental status.     

Henry M. Sheffer and Notational Relativity

Charles L. Dodgson's reputation as a significant figure in nineteenth-century logic was firmly established when the philosopher and historian of philosophy William Warren Bartley, III published Dodgson's ‘lost’ book of logic, Part II of Symbolic Logic, in 1977. Bartley's commentary and annotations confirm that Dodgson was a superb technical innovator. In this paper, I closely examine Dodgson's methods and their evolution in the two parts of Symbolic Logic to clarify and justify Bartley's claims. Then, using more recent publications and unpublished letters, I argue that Dodgson approached the elimination problem in class logic differently than his contemporaries, and in doing so, anticipated several important concepts and techniques in automated deductive reasoning. These materials also provide additional insight into his reasons for writing this book.     

Effects of long- and variable-duration signals for food on activity,instrumental responding,and eating

Incentive-motivation theories typically assume that the conditioning of appetitive motivation involves the same parameters as Pavlovian salivary conditioning. In contrast, the Soltysik-Konorski model asserts that drive is inhibited by stimuli closely associated with food (salivary CSs) and augmented by stimuli more loosely associated with food (long and variable CS-US interval). Experiment 1 examined this latter proposition. Sixty-four rats were given extensive exposure to each of four environmental CSs, two while hungry and two while satiated. Within each deprivation condition, food was given 30–300 sec after placement of the rats in one environment, and was not given in the other environment. Performance on three separate measures—activity, lever-pressing, and food consumption—was higher in the environments previously associated with food. Experiment 2 examined the effects of discrete stimuli presented in advance of eating; in accord with the results of Experiment 1, food consumption was greater after a stimulus (1- to 9-min duration) previously paired with food than after no stimulus or after a stimulus unpaired with food. The overall results indicate (a) that stimuli associated with food become capable of facilitating a variety of food-directed behaviors, possibly via the conditioning of a common appetitive system, and (b) that a close association between the stimuli and food is not essential for such conditing to occur.     

Quantitative CT scan studies in aphasia. I. Infarct size and CT numbers

Infarct si?e (number of 1-mm² pixels in the lesion) on CT scans of 30 aphasia patients was obtained with a semiautomated computer program. The mean number of lesion pixels present per slice containing lesion was approximately 500 for mild aphasias (transcortical motor and conduction), 700 for Wernicke's, 1000 for Broca's, 1500 for mixed, and 2000 for globals. These differences were significant for $\text{11}\text{15}$ of the group pairwise comparisons. When lesion locus was controlled for in the anterior/posterior plane, 73–100% of the aphasia patients were correctly classified as to type of aphasia by a discriminant analysis utilizing only the number of lesion pixels present on two CT slices. Different slice combinations were used for different aphasia group comparisons. There was a significant correlation between severity of aphasia and lesion size. There was a significant correlation between lesion size and the CT numbers in the lesion. This type of analysis may be useful to predict the prognosis for recovery potential in aphasics who have CT scans performed at 2 months poststroke.     

Communicative stress and stuttering frequency during normal,whispered, and articulation-without-phonation speech modes

The effect of communicative stress on the frequency of stuttered syllables in 12 adult stutterers reading six different but equivalent passages using normal voicing, whispering, and articulation-without-phonation speech under a stress and a non-stress condition was studied. Although the frequency of stuttering was significantly greater in the normal voicing mode than in the whispering mode and greater in the whispering mode than in the articulation-without-phonation mode, no differences were found between the stress and the nonstress conditions with respect to stuttering.     

Escape conditioning and goal punishment: Effects of acquisition trials,initial punishment trials,and CS extent

In the first of three experiments in which albino rats were given spaced shockescape trials in a straight runway, groups of 6 animals were given 6 or 24 trials followed by extinction, with or without goal-box punishment. Punishment facilitated behavior after 24 trials but did not significantly affect it after 6. Both punishment and 24 trials led to more “abrupt” extinction. In the second experiment, 6 groups of 6 animals received 6, 12, or 24 trials followed by 54 extinction trials with or without goal punishment on the first 18. All punished groups ran self-punitively, and acquisition trials effects were apparent during and after punishment. In the third experiment, buzzer extent, or duration, was manipulated, and longer extents produced stronger self-punitive effects. The results of all three experiments were interpreted in the context of presumed directive effects of aversive and conditioned aversive stimuli.     

A case of acquired aphasia and convulsive disorder: some linguistic aspects of recovery and breakdown

Among the cases of acquired aphasia and convulsive disorder several children are reported to have experienced more than one aphasic period. We present such a case in more detail, with emphasis on some characteristics of spontaneous speech. The occurrence of paraphasias, and in particular of neologisms, appeared to be associated with language recovery and breakdown. At the beginning of the period of recovery, a rapid and total disappearance of neologisms was observed, while only literal paraphasias remained. A period of language breakdown was preceded by the return of neologisms. The process was not influenced by drug therapy.     

Pauses and syntax in American sign language

Research on spoken languages has shown that the durations of silent pauses in a sentence are strongly related to the syntactic structure of the sentence. A similar analysis of the pauses (holds) in a passage in American Sign Language reveals that sequences of signs are also interspersed with holds of different lengths: long holds appear to indicate the ends of sentences; shorter holds, the break between two conjoined sentences; and the shortest holds, breaks between internal constituents. Thus, pausal analysis is a guide to parsing sentences in ASL.
