Accuracy of stereomotion speed perception with persisting and dynamic textures

It has been established that the motion in depth of stimuli visible to both eyes may be signalled binocularly either by a change of disparity over time or by the difference in the velocity of the images projected on each retina, known as an interocular velocity difference. A two-interval forced-choice stereomotion speed discrimination experiment was performed on four participants to ascertain the relative speed of a persistent random dot stereogram (RDS) and a dynamic RDS undergoing directly approaching or receding motion in depth. While the persistent RDS pattern involved identical dot patterns translating in opposite directions in each eye, and hence included both changing disparity and interocular velocity difference cues, the dynamic RDS pattern (which contains no coherent monocular motion signals) specified motion in depth through changing disparity, but no motion through interocular velocity difference. Despite an interocular velocity difference speed signal of zero motion in depth, the dynamic RDS stimulus appeared to move more rapidly. These observations are consistent with a scheme in which cues that rely on coherent monocular motion signals (such as looming and the interocular velocity difference cue) are less influential in dynamic stimuli due to their lack of reliability (i.e., increased noise). While dynamic RDS stimuli may be relatively unaffected by the contributions of such cues when they signal that the stimulus did not move in depth, the persistent RDS stimulus may retain a significant and conflicting contribution from the looming cue, resulting in a lower perceived speed.

Sex Roles - Much of what is known about father-child sexual communication is based on studies conducted in North America and more research into under-represented groups is needed. Our exploratory...     

Measuring Anxiety and Depression in Ghanaian and U.S. College Students

Differences between Ghanaian (n = 465) and U.S. (n = 425) college students on the Hopkins Symptom Checklist‐25 (HSCL‐25; Mollica, Wyshak, de Marneffe, Khuon, & Lavelle, 1987 ) were examined. Compared with their U.S. counterparts, Ghanaians reported less general distress related to anxiety and depression, more anxiety‐specific distress, and no differences in depression‐specific distress. A multidimensional approach may be most appropriate in HSCL‐25 screening for symptoms of anxiety and depression. Se examinaron las diferencias entre estudiantes universitarios ghaneses (n = 465) y estadounidenses (n = 425) en el Listado de Síntomas de Hopkins‐25 (HSCL‐25, por sus siglas en inglés; Mollica, Wyshak, de Marneffe, Khuon, & Lavelle, 1987 ). Comparados con sus homólogos estadounidenses, los ghaneses comunicaron un menor sufrimiento general relacionado con la ansiedad y depresión, un mayor sufrimiento específico relacionado con la ansiedad, y no hubo diferencias en el sufrimiento específico relacionado con la depresión. Un enfoque multidimensional puede ser el más apropiado en el chequeo de HSCL‐25 para síntomas de ansiedad y depresión.     

What is this thing called love? Desire,psychotherapy and Plato’s symposium

The platonic dialogue, Symposium, is approached here through client work. This rich and complex text is not rushed through as if the point of a conversation must be its swift and clear termination, rather than how potentially fruitful, generative and transformative it is or may come to be when we reflect or engage in further conversation. This paper suggests that Symposium presents us with two ways of thinking about relating to another, and ends with some remarks about this platonic dialogue and psychotherapy that could, of course, be followed by more conversation.     

The Revival of Panpsychism and its Relevance for the Science-Religion Dialogue

Panpsychism, whereby mentality is considered fundamental within the natural world, does not appear prima facie to be a friend to with either natural science or Christian theology. This article challenges this first impression. Within the science and theology dialogue, panpsychism has been a central component of Process theologians’ efforts to integrate these disciplines into a larger metaphysical framework; but, this is not the method adopted in this paper. Instead, it is argued that panpsychism gives scholars the potential for greater progress in two field defining discussions: quantum accounts of special divine action and theistic evolution. It is shown that panpsychism currently finds sufficient consonance with the relevant scientific disciplines and has substantial benefits for theologians engaged in these areas. Panpsychism holds great promise as the philosophy of mind for future generations of science-and-religion scholars.     

Promoting socioemotional competence in primary school classrooms: Intervention effects of the EMOscope

The aim of the study was to determine the effectiveness of a brief, teacher-led intervention (EMOscope) developed to promote children’s socioemotional competence. Our sample consisted of 339 Polish pupils and their 16 teachers from 16 third grade classrooms. Teachers in the experimental condition (8 teachers) were trained to deliver the EMOscope intervention. Data were collected at pre-test and post-test. Performance tests were administered to measure children’s social understanding and emotional awareness. Furthermore, peer ratings were used to measure children’s cooperative behaviour and teachers’ reported on children’s prosocial behaviour, hyperactivity, emotional problems, conduct problems, and peer problems. Multilevel regression analysis revealed that children in the experimental condition improved significantly on emotional self- and other-awareness and on social understanding. Moreover, they decreased in teacher-rated hyperactivity, conduct problems, and total difficulties. No effects were found, however, on teacher-rated prosocial behaviour, emotional problems, peer problems, and peer-rated cooperative behaviour.     

Systematic Review and Quality Appraisal of Practice Guidelines for Self‐Harm in Children and Adolescents

This study aimed to systematically identify and appraise clinical practice guidelines (CPGs) relating to the assessment and management of suicide risk and self‐harm in children and adolescents. Our research question is as follows: For young people (under 18 years old) presenting to clinical care with suicide ideation or a history of self‐harm, what is the quality of up‐to‐date CPGs? Using the PRISMA format, we systematically identified CPGs meeting our inclusion and exclusion criteria. Subsequently, two independent raters conducted appraisals of the eligible CPGs using the Appraisal of Guidelines for Research and Evaluation II instrument. CPGs were then classified as “poor quality,” “minimum quality,” and “high quality” using operationally defined criteria developed a priori. We identified 10 eligible CPGs published or renewed between 2005 and May 2017. Only the long‐term management of self‐harm CPGs produced by the National Institute for Health and Care Excellence met “high‐quality” criteria. Despite multiple options of CPGs published to choose from, only one was identified as “high quality,” where bias is adequately minimized. Clinicians are advised to direct resources to implementing the “high‐quality” CPG.     

Prisoners on the Fireline: The Application of Ethical Principles and Guidelines to Prison Fire Camps

Our society gives certain rights and protections to those who are punished and incarcerated, deeming them a vulnerable group in need of additional protections because they are under state control. Despite these protections, prisoners are still susceptible to mistreatment and abuse. This paper delves into one area in which prisoners are particularly vulnerable—the use of prison labor to fight wildfires in the western United States. In this paper, I first broadly discuss prison labor, before going into the current ethical principles and guidelines in the field of corrections that address the treatment of prisoners and prison labor. I argue that these principles and guidelines should be augmented to help those in corrections to make decisions about what is ethical; suggesting that how researchers evaluate proposed research projects could serve as a model for decision-making. I then introduce prison fire camps, considering whether they are ethical by research ethics principles, and suggesting how they can be changed to better reflect the values professed by our society.
