Is there a dilemma for the truthmaker non-maximalist?

Mark Jago has presented a dilemma for truthmaker non-maximalism—the thesis that some but not all truths require truthmakers. The dilemma arises because some truths that do not require truthmakers by the non-maximalist’s lights (e.g., that Santa Claus does not exist) are necessitated by truths that do (e.g., that Barack Obama knows that Santa Claus does not exist). According to Jago, the non-maximalist can supply a truthmaker for such a truth only by conceding the primary motivation for the view: that it allows one to avoid positing strange ‘negative’ entities without adopting a non-standard account of the necessary features of ordinary things. In this paper, I sketch out and defend two plausible non-maximalist proposals that evade Jago’s dilemma.     

Is there a role for psychology in ulcer disease?

The discovery of the importance of bacterial factors in the etiology of ulcer disease has led to a neglect of psychological factors. However, both earlier theoretical and empirical approaches implicating these factors are supported by more recent studies, both epidemiological and experimental. While not ignoring the unquestioned role of Helicobacter, it is important for future research to recognize the multi-factorial nature of ulcer disease by which several factors, including stress, bacteria and non-steroid anti-inflammatory drugs, may interact to drive a pre-pathology (erosions or ulcerations) to a pathological state (ulcer). Calls for general eradication programs should be cautioned in the light of possible unwanted side effects.     

Cutting Space—Cutting Body: The Nature of the Grotesque in Umwelt

We give psychological elaboration to some of Rayner’s (2011) ideas. For the idea of a space and boundaries within it many psychological explanations are possible. We elaborate the boundaries as these occur in urban contexts as well as in the flow of irreversible time (between future and past). Shifting boundaries or any act of transforming them leads to changes in the understanding of the whole. Boundaries within space and between different fields—while having a physical existence—have also a symbolic component, which is specific to human beings. We reframe the dynamic concept of boundaries along the lines of Bergson’s idea of durée, which allows us conceptualize boundaries between bodies and environments, as well as boundaries in the environment, as ever transforming in spaces of ambiguity and, following Bakhtin, grotesque. This opens way for treating the boundary phenomena as functionally emerging in person-environment—or, in von Uexküll’s terms, organism-Umwelt relation. Following Heidegger, we conclude that through dynamic boundary-making we as species dwell in the world and make the world.     

The Search for Simplicity: A Fundamental Cognitive Principle?

It is proposed that the cognitive system imposes patterns on the world according to a simplicity principle: Choose the pattern that provides the briefest representation of the available information. The simplicity principle is normatively justified-patterns that support simple representations provide good explanations and predictions on the basis of which the agent can make decisions and actions. Moreover, the simplicity principle appears to be consistent with empirical data from many psychological domains, including perception, similarity, learning, memory, and reasoning. Thus, the simplicity principle promises to serve as the starting point for the rational analysis of a wide range of cognitive processes, in Anderson's (1990, 1991a) sense. The simplicity principle also provides a framework for integrating a wide range of existing psychological proposals.     

Is there a memory for sentences?

A critical discussion of the model of sentence memory which enjoyed greatest popularity in the psycholinguistic research of the sixties, namely the model based on the deep-structure-plus-tag hypothesis of sentence memory, is presented together with the results of an experiment on prompted recall for sentences with various intervals after presentation and with two types of instructions. This experiment contributed to show that immediate memory for sentences can be affected by appropriate instructions, and that after a short time after presentation only the main semantic information of the sentences is recalled. An alternative model is presented, based on the notion of storage of the meaningful elements of the sentences in a rather abstract form, and of recall as a reconstructive process to produce new sentences. The results of two new experiments on sentence memory, the first a free and prompted recall experiment with children, the second a recognition memory study with adolescents, are then presented and discussed in relation to the model.     

Religion and rights: Is there still room for Christianity at the table?

Drawing on recent discussions about issues relating to sexual and reproductive rights in the Jamaican print and broadcast media, this article highlights the interplay between Christianity, activism and rights talk. This interplay is being framed in the local print media as a debate between two dominating hegemonic forces: on the one hand, between more ‘conservative’ and ‘fundamentalist’ Christian theological beliefs and, on the other hand, those who subscribe to what may be characterised as more ‘liberal secular fundamentalist’ viewpoints. This polarisation ignores some conciliatory scenarios that exist within other segments of Caribbean societies, theology included, that provide beneficial approaches to rights talk and work. The endeavours of some Jamaican church folks have converged with those of progressive right defenders, or, where such endeavours predate contemporary rights activism or have no direct contact with it, they might at least be viewed as benign by those who espouse such activism.     

Is there a case for the freshman women's residence hall?

Because most institutions are experiencing student migration from residence halls, the educational function of the halls is being promoted, resulting in numerous variations in design and staff organization. The purpose of this study was to investigate the merits of one of these variations—the all-freshman women's residence hall. Freshman women in three types of halls (all-freshman women, all-undergraduate women, and coeducational) were compared on the basis of academic achievement, attitudes about the campus environment, and conduct. Results indicated that on those factors, no case can be built in support of housing women in an all-freshman women's hall.     

Is there a baby in the bathwater? Maybe: some methodological issues for the de novo protein synthesis hypothesis

The de novo protein synthesis hypothesis has a long history and will no doubt continue to influence research. Yet, the primary behavioral evidence for this claim continues to come from studies in which amnesia is produced by broad scale protein synthesis inhibitors such as anisomycin. What is remarkable is the uncritical acceptance of the idea that because anisomycin is a protein synthesis inhibitor then it must have produced amnesia because it prevented translation. Several viable alternative interpretations of such experiments are discussed here and it is concluded that there is nothing to be gained by the continued use of broad-scaled antibiotics to address this hypothesis. Moreover, this approach cannot answer two critical and related questions - why must new proteins be synthesized and what are they? A focus on specific proteins such as those synthesized locally and upregulate the translation of other proteins may be a promising approach to answering these questions.     

Is there a place for Feminists in a Christian Church?

Based on a dialogue held on 16 May 1986 in London at Westminster Cathedral Hall, and organised by Catholic Women's Network and Women in Theology. Dr Daphne Hampson presents her own position at length, Dr Rosemary Ruether responds to it at length, and a discussion between the two of them follows.     

Is there stimulant sensitivity in children?

It has been suggested that exposure to stimulants alters the dopamine system and thus enhances sensitivity to stimulants and possibly other drugs. Sensitization has been induced experimentally in animals, especially in rats, and has been shown to be long-lasting. In addition, cross-sensitization across different compounds has been demonstrated. The animal data have raised concern that exposure to methylphenidate in childhood may enhance the risk for later abuse of stimulants and other drugs. We review the evidence bearing on sensitization in children treated with stimulants and followed into adulthood. None of four clinic-based studies found an excess of drug abuse in children previously treated with stimulants. A school-based longitudinal study obtained a relationship between early stimulant treatment and later drug use, without controlling for dinical confounds. The single prospective-controlled study of children who received placebo or methylphenidate does not support the sensitization hypothesis.     

Is there atypical handedness in schizophrenia?

Ninety-three schizophrenic patients and 105 normal controls were tested in a single session on an 8-item repeat-administration handedness test. The schizophrenic group, in contrast to the normal controls, showed a shift in the distribution away from right-handedness, which was due to an increase in the proportion of mixed-handers. Additional analyses revealed that the increase in mixed-handedness was largely due to an increase of within-item variability in the schizophrenic group, which we refer to as ambiguous handedness. Nearly 20% of the schizophrenic patients were inconsistent on 3 or more items compared with 3.8% of the normal controls. This increased incidence of atypical handedness is discussed within the context of disorders of attention and neurodevelopment.     

Is there space for time in social psychology publications? A content analysis across five journals

To what extent can social psychology study individuals within social contexts without strengthening theories and methods appropriate for the analysis of individual development within changing societies? Theoretical and epistemological arguments stressing the centrality of a temporal dimension are reviewed. In order to generate an objective picture of the current research practices, a standardized content analysis was carried out on 699 empirical studies published around 2000 in the European Journal of Social Psychology (EJSP), the British Journal of Social Psychology (BJSP), the Journal of Personality and Social Psychology (JPSP), the Journal of Community and Applied Social Psychology (JCASP) and Social Psychology Quarterly (SPQ). This corpus was completed by a four‐point longitudinal analysis—1972/1986/1993/2000—of BJSP, EJSP and JPSP publications. Findings reveal that most empirical studies are carried out on student samples and do not include time‐ or age‐related explanatory variables, particularly in European mainstream publications. Structural analyses taking into account research methods, research topics, journals, and countries of the first authors suggest two oppositions that organize the field of research: a laboratory versus contextualized approach and a developmental versus monographic approach of social psychology.

Contextualism: Is the act in context the adequate metaphor for scientific psychology?

According to some, psychology as it has been practiced is based on a world view known as mechanism. Individuals from a number of different areas of psychology, most recently within the behavior-analytic community, have strongly argued that psychology should be based on a different world view, contextualism. They emphasize a variety of characteristics that, in their view, differentiate a contextualistically based psychology from one based on mechanism. We examine these characteristics and find them to be of dubious value for differentiating a contextualistic approach to psychology from others. One proposal of some advocates of contextualism is that contextualistic approaches should develop independently from most of the remainder of psychology, which they regard as mechanistic. This proposal is said to be derived from the metaphilosophy of Pepper (1942). We evaluate this proposal and reject it. We go on to suggest that the mechanis-tic/contextualistic dichotomy is too constraining to realistically describe various approaches to psychology.
