EVOLUTION AND SUBJECTIVITY

Evolutionary theory is becoming an all‐encompassing form of explanation in many branches of philosophy. However, emergence theory uses the concept of self‐organization to support yet alter traditional evolutionary explanation. Biologist Stuart Kauffman suggests that the new science will need to tell stories, not simply as a heuristic device but as part of its fundamental task. This claim is reminiscent of C. S. Peirce's criticism of the doctrine of necessity. Peirce's suggestions reference Hegel, and this essay draws out this Hegelian background, addressing the question of subjectivity and issuing some Hegelian reminders so that such evolutionary and emergent theories will consider the implication of this research program on philosophy of mind. The primary focus is on two post‐Kantian, neo‐Hegelian thinkers in contemporary philosophy who deal with this problem: John McDowell and Robert Brandom.     

Social support after the loss of an infant child: A long-term perspective

The article presents findings from a survey among 251 parents whose infant child had died. For most of the parents, the loss occurred several years ago. The survey assessed the amounts of instrumental, emotional and informational support received by these parents from various sources in connection with the death. The findings revealed that different sources provided different kinds of support. There was only one significant difference between bereaved males and females with regard to amount of support: females received more emotional support from their friends than males did. Furthermore, large amounts of support received by one spouse was associated with a similar level of support received by the other spouse. Social support in connection with the death was to some extent related to long-term psychological adaptation. Particularly support from neighbours and professionals was consistently associated with psychological adaptation. In general, however, the findings with regard to long-term effects of social support were ambiguous.     

INDUSTRIAL SAFETY HAZARD REDUCTION THROUGH PERFORMANCE FEEDBACK

A “feedback package” system, designed to prevent occupational accidents and to fit directly into the normal operations of an industrial organization, was analyzed. Eighteen hazardous conditions in six production departments were assessed during seven observation sessions over a 12-week period, plus four follow-up observations over 4 months. The “feedback package” was presented in multiple baseline fashion, across subjects (department supervisors). It consisted of presenting the supervisor with copies of observational data, accompanied by a note which congratulated good practices and suggested ways for improving safety conditions, along with occasional comments from a senior executive. The results indicated that during the feedback phase, hazard rates were lower and less variable than during the baseline phase. Baseline data were highly variable with peaks ranging from 20 to 55 hazards per department. Following intervention, hazard frequencies dropped by 60%, averaged across departments, with decreases ranging from 29% to 88%. During treatment, data stabilized, with the highest frequency reaching 33. A modified feedback system was implemented by the organization following termination of the study, validating the assumption that such a system would tend to maintain.     

Does prism adaptation affect visual search in spatial neglect patients: A systematic review

Prism adaptation (PA) is a widely used intervention for (visuo‐)spatial neglect. PA‐induced improvements can be assessed by visual search tasks. It remains unclear which outcome measures are the most sensitive for the effects of PA in neglect. In this review, we aimed to evaluate PA effects on visual search measures. A systematic literature search was completed regarding PA intervention studies focusing on patients with neglect using visual search tasks. Information about study content and effectiveness was extracted. Out of 403 identified studies, 30 met the inclusion criteria. The quality of the studies was evaluated: Rankings were moderate‐to‐high for 7, and low for 23 studies. As feature search was only performed by five studies, low‐to‐moderate ranking, we were limited in drawing firm conclusions about the PA effect on feature search. All moderate‐to‐high‐ranking studies investigated cancellation by measuring only omissions or hits. These studies found an overall improvement after PA. Measuring perseverations and total task duration provides more specific information about visual search. The two (low ranking) studies that measured this found an improvement after PA on perseverations and duration (while accuracy improved for one study and remained the same for the other). This review suggests there is an overall effect of PA on visual search, although complex visual search tasks and specific visual search measures are lacking. Suggestions for search measures that give insight in subcomponents of visual search are provided for future studies, such as perseverations, search path intersections, search consistency and using a speed–accuracy trade‐off.     

Orienting numbers in mental space: Horizontal organization trumps vertical

While research on the spatial representation of number has provided substantial evidence for a horizontally oriented mental number line, recent studies suggest vertical organization as well. Directly comparing the relative strength of horizontal and vertical organization, however, we found no evidence of spontaneous vertical orientation (upward or downward), and horizontal trumped vertical when pitted against each other (Experiment 1). Only when numbers were conceptualized as magnitudes (as opposed to nonmagnitude ordinal sequences) did reliable vertical organization emerge, with upward orientation preferred (Experiment 2). Altogether, these findings suggest that horizontal representations predominate, and that vertical representations, when elicited, may be relatively inflexible. Implications for spatial organization beyond number, and its ontogenetic basis, are discussed.     

Development of the Lurian Approach: A Cultural Neurolinguistic Perspective

This article presents a discussion of the principle of extracortical organization of higher mental functions and its significance for the development of contemporary neuropsychology. The role of external factors (stimulus-mediator, symbol) in establishing functional connections between various brain systems is, in principle, universal. However, inasmuch as differing mediators and means, or significantly different details within them (direction of writing, orientation by maps or by the behavior of sea birds, etc.) may and in fact do develop in different cultures, neuropsychological analysis must take into account cross-cultural differences. Diagnostic tools must also be adapted to differing cultural contexts. The efficacy of this principle for the analysis of bilingual aphasia and of mental organization of speech, including the effect of acquisition of literacy in native language, is demonstrated. The importance of this principle for the development of new directions in applied neuropsychology is also discussed.     

Crime, Social Capital, and Community Participation

Social disorganization at the neighborhood and community levels has been consistently linked to various forms of criminal activity. However, a very much smaller body of literature addresses the effects of crime on community organizations. In some studies, crime appears to energize communities while in others, crime leads to withdrawal from community life. Using department of health crime victimization data and interviews with 2,985 low-income inner city residents living in 487 multi-family dwellings, a multi-level model examined the relationships among crime victimization, social organization, and participation in neighborhood organizations. Social organization at the individual and building levels was measured using recent formulations of social capital theory. Findings regarding crime suggested more signs of a chilling effect on participation than of an energizing effect, especially at the building level. Social capital at the building level was more strongly and consistently related to participation in community organizations than was crime.     

Acquiring new spatial intuitions: learning to reason about rotations

There are certain simple rotations of objects that most people cannot reason about accurately. Reliable gaps in the understanding of a fundamental physical domain raise the question of how learning to reason in that domain might proceed. Using virtual reality techniques, this project investigated the nature of learning to reason across the domain of simple rotations. Learning consisted of the acquisition of spatial intuitions: there was encoding of useful spatiotemporal information in specific problem types and a gradual accumulation of this understanding across the domain. This pattern of learning through the accumulation of intuitions is especially interesting for rotational motion, in which an elegant domain-wide kinematics is available to support insightful learning. Individual ability to reason about rotations correlated highly with mastery motivation, skill in fluid reasoning, and skill in reasoning about spatial transformations. Thus, general cognitive advantages aided the understanding of individual rotations without guaranteeing immediate generalization across the domain.     

Shadowed reality or the 'Prometheus-complex': analytical psychotherapy after political imprisonment and persecution

Traumatic experiences of violence like those that were brought about by the communist regime of the former German Democratic Republic (GDR) are still present as if they happened yesterday, causing severe disadvantages in everyday life even after all those years. Consequently, in cases of extreme traumatization induced by political imprisonment, persecution and applied psychological methods of disintegration, regressive processes take place which corrode the ego. The breakdown of cathexis, i.e., the failure of empathic connection at the time of the trauma, is the strongest characteristic of severe traumatization. As a result of this destruction for the traumatized there is an inability to keep upright an inner empathic, emotional connection. As we try to grasp, from a Jungian point of view, the psychodynamics of severe traumatization, we can speak of a powerful pathogenous complex, which I call the 'Prometheus-complex'. Gustav Bovensiepen speaks of this complex as a sub-network, a limited fragment of the matrix of all internalized experiences, consisting of internal working models, feelings and patterns of anticipation which interact mutually. The human being, captured in such isolation and paralysis of the mind, can find himself 'in the therapist' on a mental level.     

The shape of holes

The shape of holes can be recognized as accurately as the shape of objects (Palmer, S. E. (1999). Vision science: photons to phenomenology. Cambridge, MA: MIT Press), yet the area enclosed by a hole is a background region, and it can be demonstrated that background regions are not represented as having shape. What is therefore the shape of a hole, if any? To resolve this apparent paradox, we suggest that the shape of a hole is available indirectly from the shape of the surrounding object. We exploited the fact that observers are faster at judging the position of convex vertices than concave ones (Perception 30 (2001) 1295), and using a figural manipulation of figure/ground we found a reversal of the relative speeds when the same contours were presented as holes instead of objects. If contours were perceived as belonging to the hole rather than the surrounding object then there would have been no qualitative difference in responses to the object and hole stimuli. We conclude that the contour bounding a hole is automatically assigned to the surrounding object, and that a change in perception of a region from object to hole always drastically changes the encoded information. We discuss the many interesting aspects of holes as a subject of study in different disciplines and predict that much insight especially about shape will continue to come from holes.
