Strategic differentiation and integration among the 50 states of the USA

Recent studies demonstrate that individuals and populations (at the scale of nations) exhibiting slower life history (LH) speeds are more differentiated amongst themselves with respect to the components of life history. Faster life history individuals and populations are more integrated by comparison. This phenomenon, termed strategic differentiation–integration effort (SD–IE), has not yet been tested on a national scale, however, which is an important remaining step in establishing its generalizability at different levels of aggregation among humans. SD–IE was tested with data on five LH variables from the fifty states of the US. Effects supportive of the SD–IE hypothesis were found in all LH variables, with an average effect magnitude slightly larger than that found in studies of SD–IE at the individual differences level. This is putatively attributed to population stratification, due to the varied racial make-up of the population in the US, including European, African, Native American, and Asian ancestries from multiple countries. This study indicates that SD–IE is a generalizable phenomenon occurring at various levels of aggregation.     

What determines biological fitness? The problem of the reference environment

Organisms’ environments are thought to play a fundamental role in determining their fitness and hence in natural selection. Existing intuitive conceptions of environment are sufficient for biological practice. I argue, however, that attempts to produce a general characterization of fitness and natural selection are incomplete without the help of general conceptions of what conditions are included in the environment. Thus there is a “problem of the reference environment”—more particularly, problems of specifying principles which pick out those environmental conditions which determine fitness. I distinguish various reference environment problems and propose solutions to some of them. While there has been a limited amount of work on problems concerning what I call “subenvironments”, there appears to be no earlier work on problems of what I call the “whole environment”. The first solution I propose for a whole environment problem specifies the overall environment for natural selection on a set of biological types present in a population over a specified period of time. The second specifies an environment relevant to extinction of types in a population; this kind of environment is especially relevant to certain kinds of long-term evolution.     

Hemispheric asymmetries in the split-fovea model of semantic processing

We report a series of neural network models of semantic processing of single English words in the left and the right hemispheres of the brain. We implement the foveal splitting of the visual field and assess the influence of this splitting on a mapping from orthography to semantic representations in single word reading. The models were trained on English four-letter words, presented according to their frequency in all positions encountered during normal reading. The architecture of the model interacted with the training set to produce processing asymmetries comparable to those found in behavioral studies. First, the cueing effects of dominant and subordinate meanings of ambiguous words were different for words presented to the left or to the right of the input layer. Second, priming effects of groups of related words were stronger in the left input than the right input of the model. These effects were caused by coarser-coding in the right half compared with the left half of the model, an emergent effect of the split model interacting with informational asymmetries in the left and right parts of words in the lexicon of English. Some or all of the behavioral data for reading single words in English may have a similar origin.     

Unconsciously Poisoning the Roots: Psychological Dynamics of the Bible in Jewish/Christian Conflict

The persistence of antisemitism in Christian cultures despite the irrationality and destructiveness of its myths and attitudes has led more than one writer to consider that it may be deeply rooted in psychological dynamics, both individual and social. Likewise, much has been written about how the New Testament writings, especially certain passages in the Gospels, reflect a bitter split between the emerging Christian community and other Jewish groups. Seldom, however, are these two avenues of exploration brought together, asking how psychological mechanisms of defense and the formation of the biblical texts interact. In a recent book, The Jew and Deicide: The Origin of an Archetype (Davis, 2003), psychologist Frederick B. Davis attempted to do just that. Unfortunately, his presentation is deeply flawed by his lack of familiarity with basic New Testament studies and methods. His fundamental premise is sound—that the interplay of the texts, the communities that created them, and their subsequent interpreters evidence psychological dynamics that fuel an ongoing conflict. In this paper, I will suggest how those dynamics were active within the first century Christian community and were expressed in New Testament writings, and how those same dynamics are stimulated in later readers.Paper originally presented March 22, 2004.

Route-based travel and shared routes in sympatric spider and woolly monkeys: cognitive and evolutionary implications

Many wild primates occupy large home ranges and travel long distances each day. Navigating these ranges to find sufficient food presents a substantial cognitive challenge, but we are still far from understanding either how primates represent spatial information mentally or how they use this information to navigate under natural conditions. In the course of a long-term socioecological study, we investigated and compared the travel paths of sympatric spider monkeys (Ateles belzebuth) and woolly monkeys (Lagothrix poeppigii) in Amazonian Ecuador. During several field seasons spanning an 8-year period, we followed focal individuals or groups of both species continuously for periods of multiple days and mapped their travel paths in detail. We found that both primates typically traveled through their home ranges following repeatedly used paths, or “routes”. Many of these routes were common to both species and were stable across study years. Several important routes appeared to be associated with distinct topographic features (e.g., ridgetops), which may constitute easily recognized landmarks useful for spatial navigation. The majority of all location records for both species fell along or near identified routes, as did most of the trees used for fruit feeding. Our results provide strong support for the idea that both woolly and spider monkey use route-based mental maps similar to those proposed by Poucet (Psychol Rev 100:163–182, 1993). We suggest that rather than remembering the specific locations of thousands of individual feeding trees and their phenological schedules, spider and woolly monkeys could nonetheless forage efficiently by committing to memory a series of route segments that, when followed, bring them into contact with many potential feeding sources for monitoring or visitation. Furthermore, because swallowed and defecated seeds are deposited in greater frequency along routes, the repeated use of particular travel paths over generations could profoundly influence the structure and composition of tropical forests, raising the intriguing possibility that these and other primate frugivores are active participants in constructing their own ecological niches. Building upon the insights of Byrne (Q J Exp Psychol 31:147–154, 1979, Normality and pathology in cognitive functions. Academic, London, pp 239–264, 1982) and Milton (The foraging strategy of howler monkeys: a study in primate economics. Columbia University Press, New York, 1980, On the move: how and why animals travel in groups. University of Chicago Press, Chicago, pp 375–417, 2000), our results highlight the likely general importance of route-based travel in the memory and foraging strategies of nonhuman primates.

Varieties of Pseudo-Interior Algebras

The notion of a pseudo-interior algebra was introduced by Blok and Pigozzi in [BPIV]. We continue here our studies begun in [BK]. As a consequence of the representation theorem for pseudo-interior algebras given in [BK] we prove that the variety of all pseudo-interior algebras is generated by its finite members. This result together with Jónsson's Theorem for congruence distributive varieties provides a useful technique in the study of the lattice of varieties of pseudo-interior algebras.     

A Case Illustration of Combined Treatment Using a Psychodynamic Group for Women Sexual Abuse Survivors to Address and Modify Self-Punitive Superego Trends

Adults with childhood sexual abuse histories tend to experience severe states of guilt and shame related to their abuse, especially when the parent or caretaker had failed to intervene. In the absence of protective and loving interventions aimed at helping the child understand what happened, the adult survivor may feel inordinately culpable for the traumas rendered, as well as for resulting sequelae which may include revictimizations and victimizations of others. Homogeneous psychodynamic groups can address and modify primitive and punitive aspects of superego functioning and reduce feelings of shame and guilt. These groups also facilitate the development of benign superego functioning, thereby helping the patients become empathic toward their pasts and responsible for their current lives. While this article focuses on women, the author believes similar principles may also be applied in treatment with men.     

Process or protocol,hearts or minds?

This paper looks at the split between affective/experiential and cognitive/theoretical learning in therapeutic trainings and how trainings linked to either educational or independent institutes are in danger of not only mirroring this split, but acting it out. It is suggested that this dichotomy goes to the heart of the profession not least in the issue of how therapeutic change comes about. It is suggested that an integration of ‘knowledge’ and ‘experience’ is required in the training of reflective practitioners and that this can only be achieved through an ongoing dialogue between those involved in training clinicians.
