Descartes' Causal Principle and the Case of Body-to-Mind Causation1

It is a common view that Descartes' causal principle is to be understood in light of a similarity condition that accounts for how finite causes (as opposed, or in addition, to God) contribute to an explanation of their effects. This paper challenges this common view and offers a sui generis reading of Descartes' views on causation that has also the advantage of solving the two exegetical issues of whether Descartes thought of the body-to-mind relation in occasionalist or causal terms and of whether Descartes regarded sensory ideas innate or caused by bodies.     

Child Protection and Psychology Education in Australian Universities

Child maltreatment is a significant problem in Australia. Psychologists in a wide range of occupations play an important role in the identification and prevention of child abuse and neglect, the provision of interventions to children and families, and the development and conduct of research in related areas. Psychology graduates must be adequately prepared to work in this field; however, little is known about the extent to which child abuse and neglect related contents are taught in current university curricula. A purpose‐developed curriculum‐mapping survey was used to examine Australian undergraduate, fourth year, and postgraduate Australian Psychology Accreditation Council‐accredited programmes available in 2008. Results showed that students in the majority of programmes were exposed to child protection‐related content; however, the extent of exposure was limited. Three postgraduate units specifically addressed the prevention, identification, and response to child abuse and neglect. Course coordinators reported that child maltreatment content was mostly integrated into general units throughout the programme, typically within developmental psychology units in the undergraduate curriculum and in ethics, research, or professional issues units in the fourth year and postgraduate programmes. Results suggest the need for child protection content to be included in minimum national standards and accreditation guidelines for universities.     

Mapping One Strong ‘Ohana: Using Network Analysis and GIS to Enhance the Effectiveness of a Statewide Coalition to Prevent Child Abuse and Neglect

Network analysis and GIS enable the presentation of meaningful data about organizational relationships and community characteristics, respectively. Together, these tools can provide a concrete representation of the ecological context in which coalitions operate, and may help coalitions identify opportunities for growth and enhanced effectiveness. This study uses network analysis and GIS mapping as part of an evaluation of the One Strong ‘Ohana (OSO) campaign. The OSO campaign was launched in 2012 via a partnership between the Hawai‘i Children’s Trust Fund (HCTF) and the Joyful Heart Foundation. The OSO campaign uses a collaborative approach aimed at increasing public awareness of child maltreatment and protective factors that can prevent maltreatment, as well as enhancing the effectiveness of the HCTF Coalition. This study focuses on three elements of the OSO campaign evaluation: (1) Network analysis exploring the relationships between 24 active Coalition member organizations, (2) GIS mapping of responses to a randomized statewide phone survey (n = 1,450) assessing awareness of factors contributing to child maltreatment, and (3) Combined GIS maps and network data, illustrating opportunities for geographically-targeted coalition building and public awareness activities.     

Prose Reading in Neglect

Prose reading has been shown to be a very sensitive measure of Unilateral Spatial Neglect. However, little is known about the relationship between prose reading and other measures of neglect and its severity, or between prose reading and single word reading. Thirty participants with a first stroke in the right hemisphere and clear symptoms of spatial neglect in everyday life were assessed with tests of prose reading (text in one column book-like, and in two columns magazine-like), single words reading, and a battery of 13 tests investigating neglect. Seventy percent of these participants omitted words at the beginning of the text (left end), showing Prose Reading Neglect (PRN). The participants showing PRN differed from those not showing PRN only for the overall severity of neglect, and had a lesion centred on the insula, putamen and superior temporal gyrus. Double dissociations emerged between PRN and single word reading neglect, suggesting different cognitive requirements between the two tests: parallel processing in single word reading vs. serial analysis in text reading. Notably, the pattern of neglected text varied dramatically across participants presenting with PRN, including dissociations between reading performance of one and two columns text. Prose reading proved a complex and unique task which should be directly investigated to predict the effects of unilateral neglect. The outcome of this study should also inform clinical assessment and advises given to patients and care-givers.     

The sensory nature of knowledge: Sensory priming effects in semantic categorization

The aim of the present study was to show the perceptual nature of conceptual knowledge by using a priming paradigm that excluded an interpretation exclusively in terms of amodal representation. This paradigm was divided into two phases. The first phase consisted in learning a systematic association between a geometrical shape and a white noise. The second phase consisted of a short-term priming paradigm in which a primed shape (either associated or not with a sound in the first phase) preceded a picture of an object, which the participants had to categorize as representing a large or a small object. The objects were chosen in such a way that their principal function either was associated with the production of noise (“noisy” target) or was not typically associated the production of noise (“silent” target). The stimulus onset asynchrony (SOA) between the prime and the target was 100 ms or 500 ms. The results revealed an interference effect with a 100-ms SOA and a facilitatory effect with a 500-ms SOA for the noisy targets only. We interpreted the interference effect obtained at the 100-ms SOA as the result of an overlap between the components reactivated by the sound prime and those activated by the processing of the noisy target. At an SOA of 500 ms, there was no temporal overlap. The observed facilitatory effect was explained by the preactivation of auditory areas by the sound prime, thus facilitating the categorization of the noisy targets only.     

Auditory sensory gating and performance on the Delis–Kaplan Executive Function System

Sensory gating is a neurological mechanism that inhibits redundant sensory information. Impaired sensory gating is not uncommon in otherwise healthy individuals, but its relationship with higher level cognitive function is poorly understood. It is plausible that cognitive fragmentation associated with poor sensory gating may affect an individual's higher level executive functioning. Fifty-one participants (Mean age?=?22.02; 24 males) were administered an electroencephalogram with a paired-tone paradigm to measure sensory gating as well as a comprehensive executive functioning battery—the Delis–Kaplan Executive Function System. Overall, better performance on the D-KEFS was related to more effective sensory gating. Also, tasks that measured cognitive flexibility predicted P50 latency as well as P200 amplitude and sensory gating. Understanding the relationship between sensory gating and cognitive processing has implications for healthy individuals and clinical groups alike.     

The Occupational Therapy Elder Abuse Checklist

ABSTRACT

Occupational therapists encounter elder abuse in society and in clinical practice; however, the occupational therapy literature is void of information and tools for assessing and treating individuals at risk. Occupational therapists are in a unique position to identify elder abuse. Definitions of elder abuse, signs and symptoms of elder abuse, and reporting practices required of professionals coming in contact with individuals who may have been abused are presented. The Occupational Therapy Elder Abuse Checklist was developed to assist the occupational therapist as well as other health care professionals in uncovering abusive situations of elders who are either living alone or living with others. Guidelines are provided for use with the tool. A case study illustrates use of the tool for reporting suspected abuse, and the assessment and treatment of an individual who is a victim of elder abuse.     

Movement variability near goal equivalent manifolds: Fluctuations,control, and model-based analysis

Fluctuations in the repeated performance of human movements have been the subject of intense scrutiny because they are generally believed to contain important information about the function and health of the neuromotor system. A variety of approaches has been brought to bear to study these fluctuations. However it is frequently difficult to understand how to synthesize different perspectives to give a coherent picture. Here, we describe a conceptual framework for the experimental study of motor variability that helps to unify geometrical methods, which focus on the role of motor redundancy, with dynamical methods that characterize the error-correcting processes regulating the performance of skilled tasks. We describe how goal functions, which mathematically specify the task strategy being employed, together with ideas from the control of redundant systems, allow one to formulate simple, experimentally testable dynamical models of inter-trial fluctuations. After reviewing the basic theory, we present a list of five general hypotheses on the structure of fluctuations that can be expected in repeated trials of goal-directed tasks. We review recent experimental applications of this general approach, and show how it can be used to precisely characterize the error-correcting control used by human subjects.     

Differentiating between child protection and family support in the Canadian child welfare system's response to intimate partner violence,corporal punishment,and child neglect

Rates of reported child maltreatment nearly doubled in Canada over the period 1998–2003, an increase that reflects growing awareness of the harmful effects of an expanding array of parental behaviors, including corporal punishment, lack of supervision, and exposure to intimate partner violence (IPV). Some of these situations may benefit from voluntary family support programs outside of the child welfare system. Analyzing a sample of 11,807 investigations, this paper compares cases where the sole concern is exposure to IPV, or hitting a child, or neglect, or other forms of investigated maltreatment. Situations where exposure to IPV or potentially abusive hitting were the sole reason for investigation presented with fewer risk factors and were less likely to lead to ongoing child welfare interventions compared to other maltreatment investigations. While situations involving alleged neglect presented a higher risk profile and elicited a more intensive child welfare response than did exposure to IPV or hitting, opportunities for alternative services were nevertheless identified. The study also found that visible minority families were overrepresented in cases involving hitting and that Aboriginal families were overrepresented in cases involving neglect. Overall the findings support the development of alternative response programs in Canada.     

Into the Haunted House of Mirrors

Abstract

The treatment of youth with histories of multiple victimization is discussed. A developmental treatment approach is presented based on Eriksonian theory that highlights particular difficulties abuse presents for a child's successful movement through different developmental stages. Interventions addressing these difficulties are also discussed with many case examples. Finally, the issue is raised concerning which multiple abuse victims can be helped by the therapeutic process.
