Boolean algebra and its extra-logical sources: the testimony of mary everest boole

Mary Everest, Boole's wife, claimed after the death of her husband that his logic had a psychological, pedagogical, and religious origin and aim rather than the mathematico-logical ones assigned to it by critics and scientists. It is the purpose of this paper to examine the validity of such a claim. The first section consists of an exposition of the claim without discussing its truthfulness; the discussion is left for the sections 2–4, in which some arguments provided by the examination of the inner consistency of Mary Everest's writings, Boole's own writings, and other sources, lead to the conclusion that there are sound reasons to accept Mary Everest's viewpoint.     

suspicion of sudden infant death syndrome & injuries to infants: the effects of type of death certifier,training, and economics

This paper examines the level of suspicion by death certifiers when ruling infant deaths as accidents. Data were gathered on economic factors, amount of training in death investigation received, and personal characteristics for 1995 from 776 medical examiners or coroners. Findings indicate that personal and social factors such as age, education, and population have negligible or no effects on the level of suspicion held by death certifiers in manner of death rulings for infants. The findings from this study do suggest there is potential for inaccurate rulings of infant death due to lack of training, education, and economic resources depending on the events surrounding an infant's death and whether the death certifier is a coroner or medical examiner.     

Empathy,Awareness of Others,and Action: How Feeling Empathy for One-Among-Others Motivates Helping the Others

Feeling empathy for a member of the group may result in either favoring this individual at the expense of the group or helping the entire group. We explain these intriguing findings by proposing that the combined influence of feeling empathy for one individual and awareness of others enhances willingness to help both the individual and the others (taken as individuals). The results of three experiments showed that inducing empathy for one individual promotes favoring him or her at the expense of the group, whereas inducing empathy for one-among-others leads to helping these others individually, instead of as a group. Furthermore, the awareness of others mediated the proposed one-among-others effect.     

Memoria y adquisición del conocimiento

RESUMEN

En este artículo se sitúan los trabajos clásicos de Craik y Lockhart y Craik y Tulving en el contexto del estudio global de la memoria. Se destaca el énfasis de los dos últimos en los procesos en detrimento de las descripciones estructurales, situando la clave en el nivel de profundidad al que se procese la información y subrayando la importancia de relacionarla con nuestro conocimiento del mundo. Con relación al estudio de Craik y Tulving se examinan tres cuestiones fundamentales: el procedimiento de aprendizaje incidental, el concepto de profundidad de procesamiento y la noción de memoria episódica. Para ello revisan algunos estudios que cuestionan que el procesamiento tenga lugar únicamente de abajo a arriba a través de una jerarquía de estadios fijos -según propusieron Craik y Lockhart-, abordando diversos intentos de especificar el concepto de nivel de profundidad. La última parte se reserva al problema de identificar la noción de significado psicológico con la noción de significado procedente de la Lingüística, presentando las aportaciones de los teóricos “neogibsonianos”. El trabajo finaliza con algunas reflexiones respecto al concepto de memoria episódica aportado por Tulving.     

Do We Really Care for the World? Testing the Link between Transcendental Change Values and the Quixoteism Motive

We conducted five studies to test the transcendental change constellation (TCC)–quixoteism hypothesis: The presence of a specific set of values labeled TCC elicits a motive with the ultimate goal of increasing the welfare of the world (quixoteism). First, the salience of the TCC increased the commitment to (Study 1) and preference for (Study 2) action aimed at improving the welfare of the world. Second, the centrality of the TCC was associated with the affective reaction towards (Study 3) and support for (Study 4) a prosocial initiative when the welfare of the world was previously threatened and the initiative was aimed at improving such welfare. In Study 5, the centrality of the TCC was related to a quixotic style of life.

Processing of “unattended” threat-related information: Role of emotional content and context

Unpleasant, pleasant, or neutral visual scenes served as a context for the presentation of threat-related, positive, and neutral words. On each trial, 2 simultaneous prime words (one foveal, i.e., at fixation, and one parafoveal, i.e., 2.2° apart) appeared for 150 ms, followed by a foveally presented probe word in a lexical decision task. Results showed facilitation in response times for probe threat words when primed by an identical parafoveal word, in comparison with priming by an unrelated parafoveal word, and this effect was enhanced in an emotionally congruent unpleasant context. In contrast, no parafoveal effect appeared for positive words, even in a pleasant context. This reveals parallel processing of threat-related words outside the focus of attention.     

A Developing Approach to Studying Students’ Learning through Their Mathematical Activity

We discuss an emerging program of research on a particular aspect of mathematics learning, students’ learning through their own mathematical activity as they engage in particular mathematical tasks. Prior research in mathematics education has characterized learning trajectories of students by specifying a series of conceptual steps through which students pass in the context of particular instructional approaches or learning environments. Generally missing from the literature is research that examines the process by which students progress from one of these conceptual steps to a subsequent one. We provide a conceptualization of a program of research designed to elucidate students’ learning processes and describe an emerging methodology for this work. We present data and analysis from an initial teaching experiment that illustrates the methodology and demonstrates the learning that can be fostered using the approach, the data that can be generated, and the analyses that can be done. The approach involves the use of a carefully designed sequence of mathematical tasks intended to promote particular activity that is expected to result in a new concept. Through analysis of students’ activity in the context of the task sequence, accounts of students’ learning processes are developed. Ultimately a large set of such accounts would allow for a cross-account analysis aimed at articulating mechanisms of learning.     

Implementing flexibility in automaticity: Evidence from context-specific implicit sequence learning

Attention is often dichotomized into controlled vs. automatic processing, where controlled processing is slow, flexible, and intentional, and automatic processing is fast, inflexible, and unintentional. In contrast to this strict dichotomy, there is mounting evidence for context-specific processes that are engaged rapidly yet are also flexible. In the present study we extend this idea to the domain of implicit learning to examine whether flexibility in automatic processes can be implemented through the reliance on contextual features. Across three experiments we show that participants can learn implicitly two complementary sequences that are associated with distinct contexts, and that transfer of learning when the two contexts are randomly intermixed depends on the distinctiveness of the two contexts. Our results point to the role of context-specific processes in the acquisition and expression of implicit sequence knowledge, and also suggest that episodic details can be represented in sequence knowledge.
