The Relationship between Spatial and Communicative Egocentrism in Children and Young and Old Adults

Four age groups of 112 subjects were tested on measures of spatial and communicative egocentrism. Contrary to Piaget's assumption that the variables within his system develop in a unidirectional and irreversible fashion, a curvilinear pattern of development was found. Moreover, the relationship between the two egocentrism measures was found to be significant for only the grade 6 and college-aged samples. Nonsignificant relationships existed for the grade 2 and elderly groups. The findings are discussed in terms of neurological disintegration in the elderly.     

Patterns of Human Interlimb Coordination Emerge from the Properties of Non-Linear,Limit Cycle Oscillatory Processes

The present article represents an initial attempt to offer a principled solution to a fundamental problem of movement identified by Bernstein (1967), namely, how the degrees of freedom of the motor system are regulated. Conventional views of movement control focus on motor programs or closed-loop devices and have little or nothing to say on this matter. As an appropriate conceptual framework we offer Iberall and his colleagues’ physical theory of homeokinetics first elaborated for movement by Kugler, Kelso, and Turvey (1980). Homeokinetic theory characterizes biological systems as ensembles of non-linear, limit cycle oscillatory processes coupled and mutually entrained at all levels of organization. Patterns of interlimb coordination may be predicted from the properties of non-linear, limit cycle oscillators. In a set of experiments and formal demonstrations we show that cyclical, two-handed movements maintain fixed amplitude and frequency (a stable limit cycle organization) under the following conditions: (a) when brief and constantly applied load perturbations are imposed on one hand or the other, (b) regardless of the presence or absence of fixed mechanical constraints, and (c) in the face of a range of external driving frequencies from a visual source. In addition, we observe a tight phasic relationship between the hands before and after perturbations (quantified by cross-correlation techniques), a tendency of one limb to entrain the other (mutual entrainment) and that limbs cycling at different frequencies reveal non-arbitrary, sub-harmonic relationships (small integer, subharmonic entrainment). In short, all the above patterns of interlimb coordination fall out of a non-linear oscillatory design. Discussion focuses on the compatibility of these results with past and present neurobiological work, and the theoretical insights into problems of movement offered by homeokinetic physics. Among these are, we think, the beginnings of a principled solution to the degrees of freedom problem, and the tentative claim that coordination and control are emergent consequences of dynamical interactions among non-linear, limit cycle oscillatory processes.     

Major Factors of Personality

Summary

French has recently resurveyed the literature regarding personality factors in order to (a) update his previous survey and (b) complement, in the noncognitive domain, the prestigious French, Ekstrom, and Price kit of reference tests for cognitive factors. This recent survey of personality factors is limited in at least two respects: (a) it relies on studies which are, in most cases, limited in size of item pools; (b) it has been greatly influenced by the two systems of Cattell and Guilford. Rather than rely on the pre-1971 literature (which belongs to an era when the factor analysis of a hundred variables was “a large factor analysis”), the writer has undertaken research aimed at accurate delineation of personality factors using itemfactoring coupled with item analysis. The article has two purposes: (a) to compare the factors in French's survey with those emerging in very recent work, and (b) to make the point that we are now likely to achieve greater comprehensiveness and accuracy in the identification of major personality factors.     

RE: From Prefix to Paradigm

This article is a translated chapter from a large study of the philosophy of ecology and biology. It looks at the vast array of reiterative processes in nature and culture and argues that continuous recursion is the core activity that sustains living processes at all levels. Therefore, the prefix “re,” which is central to the concepts of repetition, renewal, reinforcement, regeneration, reorganization, recursion, and religion, is a radical concept that should be considered at the paradigmatic level. The author shows that by working “revolutions into its revolutions” the process of RE complexly unifies and intermixes the past and future in order to generate the creative pulse of evolution.     

Wilhelm Reich and Anna Freud: His expulsion from psychoanalysis

This article describes the growth of hostility towards Wilhelm Reich in the psychoanalytic community over his Marxist ideology and activism as well as disagreements over the death instinct. It brings to the fore the behind the scenes political manipulations between Ernest Jones and Anna Freud to effect the expulsion of Reich both from the Vienna and Berlin local psychoanalytic societies and from the International Psychoanalytic Association (IPA). It describes Reich's reactions to these events and the pressure placed on other psychoanalysts to stop supporting him and also the revision of history about the expulsion. It discusses the use of the term "crazy" as it was used in the psychoanalytic movement. Further the article discusses personality attributes of Anna Freud leading to counter-transference possessiveness to children and women, especially patients. It briefly touches on the attitudes of both Sigmund and Anna Freud toward sex and how this furthered the clash with Reich. It discusses the similarity between Anna's actions toward the Burlingham children and what happened to the children of Reich.     

Knowledge and the value of cognitive ability

We challenge a line of thinking at the fore of recent work on epistemic value: the line (suggested by Kvanvig in The value of knowledge and the pursuit of understanding, 2003 and others) that if the value of knowledge is “swamped” by the value of mere true belief, then we have good reason to doubt its theoretical importance in epistemology. We offer a value-driven argument for the theoretical importance of knowledge—one that stands even if the value of knowledge is “swamped” by the value of true belief. Specifically, we contend that even if knowledge itself has no special epistemic value, its relationship to other items of value—cognitive abilities—gives ample reason to locate the concept at the very core of epistemology.     

Spinoza’s error: Memory for truth and falsity

Two theoretical frameworks have been proposed to account for the representation of truth and falsity in human memory: the Cartesian model and the Spinozan model. Both models presume that during information processing a mental representation of the information is stored along with a tag indicating its truth value. However, the two models disagree on the nature of these tags. According to the Cartesian model, true information receives a “true” tag and false information receives a “false” tag. In contrast, the Spinozan model claims that only false information receives a “false” tag, whereas untagged information is automatically accepted as true. To test the Cartesian and Spinozan models, we conducted two source memory experiments in which participants studied true and false trivia statements from three different sources differing in credibility (i.e., presenting 100% true, 50% true and 50% false, or 100% false statements). In Experiment 1, half of the participants were informed about the source credibility prior to the study phase. As compared to a control group, this precue group showed improved source memory for both true and false statements, but not for statements with an uncertain validity status. Moreover, memory did not differ for truth and falsity in the precue group. As Experiment 2 revealed, this finding is replicated even when using a 1-week rather than a 20-min retention interval between study and test phases. The results of both experiments clearly contradict the Spinozan model but can be explained in terms of the Cartesian model.     

Establishing Connections between Aristotle's Natural Deduction and First-Order Logic

This article studies the mathematical properties of two systems that model Aristotle's original syllogistic and the relationship obtaining between them. These systems are Corcoran's natural deduction syllogistic and ?ukasiewicz's axiomatization of the syllogistic. We show that by translating the former into a first-order theory, which we call T _RD, we can establish a precise relationship between the two systems. We prove within the framework of first-order logic a number of logical properties about T _RD that bear upon the same properties of the natural deduction counterpart – that is, Corcoran's system. Moreover, the first-order logic framework that we work with allows us to understand how complicated the semantics of the syllogistic is in providing us with examples of bizarre, unexpected interpretations of the syllogistic rules. Finally, we provide a first attempt at finding the structure of that semantics, reducing the search to the characterization of the class of models of T _RD.     

Patterns of Memory Performance in Children with Controlled Epilepsy on the CVLT-C

Decreased memory skills have been reported in children with epilepsy. However, standardized instruments to evaluate learning and memory in children have been unavailable until recently. The present study was designed to assess memory patterns in children with epilepsy based on the California Verbal Learning Test-Children's Version (CVLT-C). The test was administered to 44 children with complex partial seizures and 21 children with generalized seizures between 8 and 13 years of age. Children in the study had been treated for epilepsy for at least 6 months, had well-controlled seizures on monotherapy, and had no evidence of anticonvulsant toxicity. Children with head injuries, learning disabilities, or hyperactivity were excluded. Test results did not reflect differences in memory performance based on seizure type. Scores for the entire sample indicated intact new learning, decreased intrusions and perseverative responses, and better short-term than long-term delayed recall. Recognition skills were stronger than long-term delayed recall skills and suggested that memory performance may be improved for these children when a multiple-choice format is available in academic settings.
