Descartes on the distinction between primary and secondary qualities

ABSTRACT

Descartes did not use the terms ‘primary’ and ‘secondary’ qualities, but a similar distinction emerges from his texts: certain qualities of objects (such as size and shape) are intrinsic properties of matter, whereas others (like colours and smells) are products of the interaction with a perceiver. A common interpretation states that the division between primary and secondary qualities is explained by the way in which we are acquainted with them: an idea of a primary quality is similar to its physical causes, and it is clearly and distinctly perceived by the intellect. An idea of a secondary quality is dissimilar to its physical causes and it is obscurely and confusedly perceived by the senses. This view receives the name of ‘bifurcation reading’ (Simmons, A. ‘Descartes on the Cognitive Structure of Sensory Experience’. Philosophy and Phenomenological Research, LXVII, no. 3 (November 2003)). While it integrates well some textual occurrences, it creates a problematic fragmentation within single acts of perception. This paper contends that this reading is incorrect. It presents several arguments for the claim that the distinction of qualities is due to the different ways in which our ideas of them misrepresent their physical causes. Then, Descartes’ dissimilarity thesis between physical objects and our ideas of them remains a structural feature of his theory of sensory perception and not a local phenomenon affecting only ideas of secondary qualities.     

The Relationships Among Sensory Processing Styles,Personality Traits,and Body Mass Index: A Pilot Study

The purpose of the authors in this study is to explore the possible relationships among sensory processing styles, possible sensory processing disorders, personality traits, and body mass index. There is research on the relationship between obesity as defined by body mass index and temperament, and sensory processing and temperament; however, no information could be found on the relationship between body mass index and sensory processing styles, or the role that temperament and personality styles may play in these relationships. The 50 female participants were recruited from the University of New England community. The sample included women between the ages of 19 and 59 years, and of various weights. None of the participants had a history of thyroid problems, diabetes, or any physical disabilities that would limit daily physical activity. None had been diagnosed with sensory processing disorder. All participants filled out two self-reports and a demographic questionnaire. The Adult/Adolescent Sensory Profile (Brown &; Dunn, 2002 Brown , C. E. , &; Dunn , W. ( 2002 ). Adult/Adolescent Sensory Profile . San Antonio , TX : The Psychological Corporation . [Google Scholar]) determines a person's sensory processing style and possible sensory processing disorder, and the Basic Personality Inventory (Jackson, 1996 Jackson , D. N. ( 1996 ). Basic Personality Inventory Manual , (2nd ed.) . Port Huron , MI : Sigma Assessment  [Google Scholar]) focuses on everyday behaviors to describe temperament and “adult behavioral syndromes” (p. 5). Through this study the authors show only tentative relationships between body mass index and sensory processing styles and personality traits. The data could be interpreted to support both discriminant and convergent validity between the Adult/Adolescent Sensory Profile and the Basic Personality Inventory. There were, however, significant correlations between aspects of sensory processing and aspects of personality that appeared to strengthen the idea that differences in sensory processing result in predictable types of behavior, indicating that sensory processing disorders are a separate diagnostic category.     

Sensory substitution: an approach to the experimental study of perception / Sustitución sensorial: un abordaje para el estudio experimental de la percepción

Abstract

Sensory substitution refers to the phenomenon where object and environment information normally acquired through one sense can be obtained by another sense. For example, visual input being provided by hearing or touching. Sensory substitution devices are technological designs that transform the characteristics of one sensory modality into stimuli of another sensory modality. These devices were developed with two purposes: (1) to assist people with sensory disabilities in daily tasks; and (2) to study the involved mechanisms of brain plasticity. This article reviews studies in which sensory substitution phenomenon is employed as a methodological strategy to study visual perception. Furthermore, its use is discussed as an experimental platform to contrast new perceptual theories and underlying neurophysiological mechanisms that are currently under review.     

Neglecting neglect: some thoughts about children who have lacked good input,and are ‘undrawn’ and ‘unenjoyed’

This paper looks at emotional neglect in the early years of life, and postulates some probable long-term sequelae of such neglect. It argues that there is a continuum of neglect; ranging from the severest form, as seen in institutional orphanages, to milder variations. A range of theoretical and research traditions, including developmental psychology, attachment theory and neuroscience are used, alongside psychoanalytic ideas, to attempt to delineate some of the key features and patterns that arise. A question is raised as to whether we have sufficient diagnostic categories or theoretical ideas to make sense of neglected children. Thought is given to the very specific clinical challenges of working with children who are neglected, and how the clinical task might differ from working with children who have suffered other forms of early damage, such as physical abuse. It is argued that these children suffer a multiple, overdetermined form of neglect; their initial neglect because of the form of caretaking they did (or did not) receive being compounded by their inability to use help and then also the tendency of professionals to similarly neglect these children, who can be difficult to relate to and hard to ‘warm’ to.     

Dating Violence Perpetration: The Predictive Roles of Maternally versus Paternally Perpetrated Childhood Abuse and Subsequent Dating Violence Attitudes and Behaviors

This study investigated both young men's and young women's perpetration of physical, sexual, and psychological forms of dating violence, examining predictors of violence including maternally or paternally perpetrated forms of various types of child maltreatment, as well as attitudes toward dating violence and dating violence victimization. Results of hierarchical linear regressions found that childhood experiences of maternal neglect predicted men's physical perpetration, and childhood sexual abuse predicted women's sexual perpetration and men's psychological perpetration. Further, positive attitudes toward dating violence predicted women's physical, psychological, and sexual perpetration, as well as men's sexual perpetration, and experiences of dating violence victimization were the strongest predictors of most forms of dating violence perpetration, particularly among women. Implications for future research and prevention initiatives are discussed.     

A Controlled Pilot-Outcome Study of Sensory Integration (SI) in the Treatment of Complex Adaptation to Traumatic Stress

This study tested whether sensory integration (SI) treatment combined with psychotherapy would improve symptom outcome over psychotherapy alone in the treatment of complex posttraumatic stress, as measured by the Disorders of Extreme Stress Not Otherwise Specified (DESNOS) clinical construct in a group of 10 adult patients with histories of childhood abuse. DESNOS symptoms were assessed at three time periods (T1, baseline; T2, after experimental group SI treatment; and T3, after wait-list control group SI treatment) using the Structured Interview for Disorders of Extreme Stress (SIDES). The Sensory Learning Program? (SLP), developed by the Sensory Learning Institute of Boulder, Colorado, was used as the SI treatment modality. Results indicated significant differential improvement for the group treated with SLP in SIDES Total Score (T1/T2 and T2/T3), Self Perception (T1/T2 and T2/T3), Affect Regulation (T2/T3), and Alterations in Meaning (T1/T2).     

Preface

Summary

Child victimization is a serious and on-going problem in the United States and throughout the world. In 2000, an estimated 900,000 children were victims of abuse and neglect in the United States. New and different responses to child maltreatment will have to be developed and implemented in response to the increasingly diverse contexts and situations within which maltreatment occurs. Emerging trends in adult-child boundary violations are explored within this volume from a cross-section of disciplines, including law, sociology, criminal justice, psychology, and health services. The selections analyze issues critical to child maltreatment and offer intriguingly different perspectives of present and future issues related to child abuse.     

No Safe Place

Summary

This article addresses ethical issues associated with the concept of professional and scientific responsibility as related to Principle C, “Integrity” of the APA's 2002 Ethics Code. Differences between aspirational and enforceable ethical standards are noted and contextualized in APA's and other professional society's ethics codes. Three case examples are presented and discussed.
