The Perennial Freud: Method versus Myth and the Mischief of Freud Bashers

Nowadays Freud bashing is not only à la mode, in certain circles it has become de rigueur. Once a name of respect, Freud has become a name of ridicule. But like any scientific method, body of knowledge, and therapeutic procedure, psychoanalysis should be subjected to critical scrutiny. The recent crop of hostile Freud critics may have filled a vacuum left for decades by a psychoanalytic establishment which, like the Church of yesteryear, shunned all forms of criticism intramural and extramural. A central guiding idea of this essay is the distinction between the psychoanalytic method and psychoanalytic doctrines, hypotheses, and theories. This distinction has been invariably confused by both Freud's adherents and Freud's attackers. Moreover, arguments ad rem have been conflated with arguments ad hominem. A socially responsible criticism must seek to be constructive and not merely destructive. It is the latter course that was taken by the various hostile critics that came to be labeled as Freud bashers. The time has come to take a stand against the more egregious attacks on Freud and the psychoanalytic method.     

The Meaning of Meaning-Fallibilism

Much discussion of meaning by philosophers over the last 300 years has been predicated on a Cartesian first-person authority (i.e. “infallibilism”) with respect to what one’s terms mean. However this has problems making sense of the way the meanings of scientific terms develop, an increase in scientific knowledge over and above scientists’ ability to quantify over new entities. Although a recent conspicuous embrace of rigid designation has broken up traditional meaning-infallibilism to some extent, this new dimension to the meaning of terms such as “water” is yet to receive a principled epistemological undergirding (beyond the deliverances of “intuition” with respect to certain somewhat unusual possible worlds). Charles Peirce’s distinctive, naturalistic philosophy of language is mined to provide a more thoroughly fallibilist, and thus more realist, approach to meaning, with the requisite epistemology. Both his pragmatism and his triadic account of representation, it is argued, produce an original approach to meaning, analysing it in processual rather than objectual terms, and opening a distinction between “meaning for us”, the meaning a term has at any given time for any given community and “meaning simpliciter”. the way use of a given term develops over time (often due to a posteriori input from the world which is unable to be anticipated in advance). This account provocatively undermines a certain distinction between “semantics” and “ontology” which is often taken for granted in discussions of realism.     

Pedagogy of Play

“Pedagogy of play” focuses on the educational value of this field of experience, by claiming that play characterizes the two fundamental guidelines which are at the basis of education; the spontaneous and natural direction on the one side, and the intentional one on the other side. It is commonly assumed that pedagogy of play concerns only the latter of the two above-mentioned aspects of education, that is to say the design and management of playing experiences and materials with clear educational goals; instead, this discipline critically analyzes the whole playing experience, therefore trying to grasp its potentialities, its material conditions, and its overall meanings in the making of the subject. Moving from some considerations about the discovery of play as an emblematic index of the “discovery of childhood” at the beginning of Modern Age (Ariès, 1960), the first part of this essay underlines three aspects: the first concerns the investment on play as an educational device (from Locke to Montessori, up to Children’s Museums), pointing out the shift from the classic principle of ludendo docere to the modern ludendo discere. The second aspect focuses on the retrieval of the natural dimension of play, which finds in Rousseau its main source; the third takes into consideration toys and their identity both as pedagogical devices and as media. In the second part of the essay, the focus is on free play and its educational value, which is here interpreted especially as the first field of experience for children’s “political education”. The final remarks include some speculations the relationship between play and daily life, suggesting the idea that “life-long playing” could be defined as a meaningful aspect of long-life education.     

Why psychology needs conceptual analysts: Wachtel's “discontents” revisited

Commenting on Wachtel's “Investigation and its Discontents” [Wachtel, P. L. (1980). Investigation and its discontents: Some constraints on progress in psychological research. American Psychologist, 35, 399–408], I agree that lack of support for a career path of conceptual analysis and critique is a serious problem. Psychology requires a strong conceptual component because it is subject to unusual distortions and self-deceptions in theory formation and evidential evaluation due to issues of power, self-esteem, and social ideology. I agree with Wachtel that pressures for quantity of publication are detrimental to scientific quality, but dispute his suggestion that excessive focus on quantity in assessing productivity can be addressed by having tenure and promotion candidates submit only their three best papers. Such reviews must be based on the entire record, so improvements must involve journals’ acceptance standards. Regarding Wachtel's concern about the influence of grants on reviews, I argue that grants should be relevant only to the extent they bear on the candidate's scholarly goals.     

Pragmatic reasoning schemas

We propose that people typically reason about realistic situations using neither content-free syntactic inference rules nor representations of specific experiences. Rather, people reason using knowledge structures that we term pragmatic reasoning schemas, which are generalized sets of rules defined in relation to classes of goals. Three experiments examined the impact of a “permission schema” on deductive reasoning. Experiment 1 demonstrated that by evoking the permission schema it is possible to facilitate performance in Wason's selection paradigm for subjects who have had no experience with the specific content of the problems. Experiment 2 showed that a selection problem worded in terms of an abstract permission elicited better performance than one worded in terms of a concrete but arbitrary situation, providing evidence for an abstract permission schema that is free of domain-specific content. Experiment 3 provided evidence that evocation of a permission schema affects not only tasks requiring procedural knowledge, but also a linguistic rephrasing task requiring declarative knowledge. In particular, statements in the form if p then q were rephrased into the form p only if q with greater frequency for permission than for arbitrary statements, and rephrasings of permission statements produced a pattern of introduction of modals (must, can) totally unlike that observed for arbitrary conditional statements. Other pragmatic schemas, such as “causal” and “evidence” schemas can account for both linguistic and reasoning phenomena that alternative hypotheses fail to explain.     

Fatigue and alertness in the United States railroad industry part I: the nature of the problem

The railroad industry must actively manage employee fatigue and alertness problems to maintain an optimal level of operational safety and productivity. Given the necessity to operate nights and irregular hours, weekends and holidays under a wide range of physical conditions and service demands, we must explore every reasonable avenue to ensure employees are fit, alert, and well-rested. Effective fatigue management programs must address train crews, dispatchers, signalmen, track workers, and others – both operating and non-operating personnel. Work scheduling is a particular problem in on-call operations because of start-time variability, “call” predictability, and the common use of “shorter-than 24-h work/rest schedules”. Extensive night operations are incompatible with normal circadian rhythms. Staffing limitations often require extensive overtime and reduce the effectiveness of any work schedule. These and other institutional factors significantly contribute to employee sleep deficit and overall fatigue. Lack of alertness and reduced vigilance are related not only to sleep disruption and resulting sleep deficits, but also to cognitive workload, workload transition, the physical working environment, and the design of advanced control systems. Ongoing research into fatigue mitigation and alertness enhancement strategies and into advanced technologies such as Positive Train Control (PTC) can lead to improvements. These include better labor–management agreements, more effective fatigue-related educational programs, improved schedule regularity, and more practical and adaptable federal laws and regulations.     

A consistency-based framework for merging knowledge bases

We present a framework for expressing various merging operators for belief sets. This framework generalises our earlier work on consistency-based belief revision and contraction. Two primary merging operators are identified: in the first approach, belief sources are consistently combined so that the result of merging knowledge bases K₁,…,K_n is a maximal consistent (if possible) set of formulas comprising the joint knowledge of the knowledge bases. This approach then accords with one's intuitions as to what a “merge” operator should do. The second approach is more akin to a generalised belief revision operator. Knowledge bases K₁,…,K_n are “projected” onto another (in the simplest case the knowledge base where only tautologies are known). Properties of these operators are investigated, primarily by comparing their properties with postulates that have been identified previously in the literature. Notably, the approach is independent of syntax, in that merging knowledge bases K₁,…,K_n is independent of how each K_i is expressed. As well, we investigate the role of entailment-based and consistency-based integrity constraints, the interrelationships between these approaches and belief revision, and the expression of further merging operators.     

Gadamer and the Otherness of Nature: Elements for an Environmental Education

In this work I search for elements that contribute to the development of the ethical dimension of environmental education. I start with the existence of what C.A. Bowers calls “areas of silence” in the curriculum in both schools and universities. The reason for this silence, I argue, is to be found in the Cartesian conceptual structures of curricula. I suggest that the works of Bacon, Galileo and Descartes provoke a twofold process that I have termed the forgetting of tradition and objectification of nature. As a corrective to this process, I explore the possibilities that the philosophical hermeneutics of Hans-Georg Gadamer opens for rehabilitation of tradition and de-objectification of nature. I work with the concept of the “dignity of things” present in Greek dialectics: that nature is not simply a projection of mind (as the neo-Kantians claim), but something that thought suffers. In my conclusions I argue that for nature to be reinserted into almost all areas of knowledge it is necessary that we respect “the otherness of nature.”     

Speech-associated gestures, Broca’s area, and the human mirror system

Speech-associated gestures are hand and arm movements that not only convey semantic information to listeners but are themselves actions. Broca’s area has been assumed to play an important role both in semantic retrieval or selection (as part of a language comprehension system) and in action recognition (as part of a “mirror” or “observation–execution matching” system). We asked whether the role that Broca’s area plays in processing speech-associated gestures is consistent with the semantic retrieval/selection account (predicting relatively weak interactions between Broca’s area and other cortical areas because the meaningful information that speech-associated gestures convey reduces semantic ambiguity and thus reduces the need for semantic retrieval/selection) or the action recognition account (predicting strong interactions between Broca’s area and other cortical areas because speech-associated gestures are goal-direct actions that are “mirrored”). We compared the functional connectivity of Broca’s area with other cortical areas when participants listened to stories while watching meaningful speech-associated gestures, speech-irrelevant self-grooming hand movements, or no hand movements. A network analysis of neuroimaging data showed that interactions involving Broca’s area and other cortical areas were weakest when spoken language was accompanied by meaningful speech-associated gestures, and strongest when spoken language was accompanied by self-grooming hand movements or by no hand movements at all. Results are discussed with respect to the role that the human mirror system plays in processing speech-associated movements.     

Processing doubly quantified sentences: Evidence from eye movements

We investigated the processing of doubly quantified sentences, such asKelly showed a photo to every critic, that are ambiguous as to whether the indefinite (a photo) specifies single or multiple referents. Ambiguity resolution requires the computation of relative quantifier scope: Whether a or every takes wide scope, thereby determining how many entities or events are to be represented. In an eye-tracking experiment, we manipulated quantifier order and whether continuations were singular or plural, for constructions with the direct or the indirect object occurring first. We obtained effects consistent with the on-line processing of relative scope at the doubly quantified phrase and considered two possible explanations for a preference for singular continuations to the quantified sentence. We conclude that relative quantifier scope is computed on line during reading but may not be a prerequisite for the resolution of definite anaphors, unless required by secondary tasks.     

Ethos,pathos and logos in Aristotle's Rhetoric: A re-examination

In Aristotle's Rhetoric, logos must be conceived as enthymematical argumentation relative to the issue of the case. Ethos and pathos also can take the form of an enthymeme, but this argumentation doesn't relate (directly) to the issue. In this kind of enthymeme, the conclusion is relative to the ethos of the speaker or (reasons for) the pathos of the audience. In an ideal situation — with a good procedure and rational judges — logos dominates and in the real situation of Aristotle's time — with an imperfect procedure and irrational judges — ethos and pathos prevail.I should like to thank R. Berkenbosch and J. Wisse for their comments.     

The relationship between speed of information processing and cognitive ability

Speed of information processing as measured by various reaction time and inspection tasks has been shown to correlate with psychometric intelligence, and it has been suggested that general intelligence (g) is determined to some degree by the speed that information is processed. If this is so, then various measures of speed of information processing should correlate substantially with each other, and each should also correlate with a wide range of psychometric tests that load on g. Alternatively, intelligence may be considered to be a multi-faceted complex of partially related abilities with specific abilities being dependent upon specific cognitive processes. If this is the case, it should be possible to discover independent cognitive processes, some of which correlate with one facet or broad ability and some with another. This paper presents three experiments in which the relationship between intellectual ability and four speed of information processing measures was examined. These were rate of memory scanning, rate of retrieval of information from long term memory, speed of stimulus-response mapping and inspection time (IT). Results showed that correlations between IT and most reaction time measures of speed of information processing were low, and that correlations between different versions of IT were negligible. In addition, some cognitive tasks with verbal material (memory scanning rate for digits and Posner letter matching IT) correlated most substantially with Verbal Reasoning whereas non-verbal (two-line) IT consistently correlated with tests loading on g. It was thus suggested that while non-verbal IT may be a measure of a perceptual speed attribute that contributes to mental functioning, other “speed of information processing” parameters may be more specific to a subset of abilities.     

Impulsiveness and anxiety: Information processing and electroencephalograph topography

Within a general systems model of personality, we are currently studying impulsiveness and other personality traits using multitrait-multimethod multivariate designs. The research involves a wide spectrum of techniques in an effort to find consistent relationships among biological, cognitive, behavioral, and environmental correlates of the personality traits. The goal is to develop unique profiles of personality traits based on these four classes of measurements. Our research has demonstrated that impulsiveness and anxiety are personality traits that have loadings on two orthogonal higher order personality factors that we have labeled action-oriented and mood-feeling. From both an empirical research and a clinical viewpoint, we have identified three subtraits of impulsiveness: cognitive (Ic), motor (Im), and nonplanning (Inp). Inp is hypothesized to relate to frontal lobe brain processes, while Ic and Im are more related to neural mechanisms that (1) control performance on tasks with “timing-and-rhythm” demands and/or (2) are related to seizure disorders. High-impulsive subjects (especially when high on Ic and Im) are less efficient at performing a wide range of psychomotor tasks. We hypothesize that this inefficiency relates to the information-gating properties of the nervous system being out of “synch” with efficient performance of selected tasks. High-impulsive subjects are visual N100 event-related potential augmentors, which would be consistent with this dyssynchrony occurring in the early stages of information processing. We also hypothesize that impulsiveness is related to serotonin (high impulsiveness related to low serotonin levels). Our psychopharmacological-psychophysiological studies of information processing would be consistent with the latter hypothesis.     

Locus of control and the perception of freedom in an agent of reinforcement

Internals and externals observed a staged videotape presentation that portrayed a “teacher” and a “learner” engaging in a 20-item anagrams task. For externals, any variability (10, 50, and 90% schedule) in the reinforcing behavior of the “teacher” (agent of reinforcement) resulted in significantly greater perceived freedom than when no variability (0 and 100% schedule) occurred in behavior. For internals, perceived freedom was a negative linear function of the amount of reinforcement administered. Internals indicated that they could influence the behavior of the “teacher” in all reinforcement conditions, whereas externals indicated that they could influence only the “teachers” in the variable reinforcement conditions. It was concluded that greater freedom is attributed to a person whose behavior is perceived as congruent with the person's inner disposition.     

Transcendence of the Ego (The Non-Existent Knight)

I exist, but I am not a thing among things; X exists if and only if there is something such that it=X. This is consistent, and it is a view that can be supported. Calvino’s novel The Non‐Existent Knight can be read so as to illustrate this view. But what is my relation to the things there are if I am not identical with any of them – things such as my arms, my garden, the city I live in? I name this the Gurduloo problem, after the Knight’s page. This relation must be one that admits of degrees; I suggest that we say that I manifest myself through the things thus associated with me. Several pseudo‐problems, pertaining to volitional action, supervenience, observability, and the emergence of consciousness, dissolve upon inspection.
