Perception of coherent motion in random dot displays by pigeons and humans

Pigeons and humans were required to discriminate coherent from random motion in dynamic random dot displays. Coherence and velocity thresholds were determined for both species, and both thresholds were found to be substantially higher for pigeons than for humans. The results are discussed with reference to differences in motion processing in mammals and birds. It is suggested that the inferior motion sensitivity of pigeons can be attributed to poorer spatiotemporal motion integration.     

Spiritual Practice,Health Promotion,and the Elusive Soul: Perspectives from Public Health

Spirituality and religion are topics of increasing interest in U.S. society and popular culture as well for many health professions, including medicine, psychology, and public health. This article comments on Mark Graves’ (2008) synthesis of science and spirituality/religion, Mind, Brain, and the Elusive Soul from the perspective of a public health professional. I briefly review the sources, extent, and conceptual approaches of emerging scientific and health interest in spirituality/religion. Spiritual practices are identified as phenomena of central interest. Major concepts of Graves’ synthesis are reviewed, and the soul’s relevance to spiritual growth, popular culture, and scientific application is discussed. Several questions are posed as a stimulus to further extension and refinement of Graves’ synthesis.     

The benefit of interleaved mathematics practice is not limited to superficially similar kinds of problems

Most mathematics assignments consist of a group of problems requiring the same strategy. For example, a lesson on the quadratic formula is typically followed by a block of problems requiring students to use that formula, which means that students know the appropriate strategy before they read each problem. In an alternative approach, different kinds of problems appear in an interleaved order, which requires students to choose the strategy on the basis of the problem itself. In the classroom-based experiment reported here, grade 7 students (n = 140) received blocked or interleaved practice over a nine-week period, followed two weeks later by an unannounced test. The mean test scores were greater for material learned by interleaved practice rather than by blocked practice (72 % vs. 38 %, d = 1.05). This interleaving effect was observed even though the different kinds of problems were superficially dissimilar from each other, whereas previous interleaved mathematics studies had required students to learn nearly identical kinds of problems. We conclude that interleaving improves mathematics learning not only by improving discrimination between different kinds of problems, but also by strengthening the association between each kind of problem and its corresponding strategy.     

Topic-focused analysis in a case of integrative psychotherapy with a father fearing his own anger

Even though evidence-based knowledge is considered the foundation of clinical practice, many clinicians question the clinical relevance of published research. Clinicians increasingly define themselves as having an integrative stance, in contrast to the tendency for most research to be based on clearly defined psychotherapies. Qualitative single case studies make it possible to generate knowledge about what actually occurs in integrative therapy. Topic change process analysis (TCPA) is used in the analysis of brief integrative therapy conducted by a very experienced psychotherapist drawing on a complex variety of therapeutic approaches. The client was a man in his late thirties, worrying about his strong anger, particularly related to one of his children. Analysis of topic areas, topic shifts, response patterns within topics and changes in perspective made it possible to identify key processes and key patterns of the therapy which resulted in a very positive outcome for the client. Implications of these findings for practice, and future research, are discussed.     

Combining Indian and Western Spiritual Psychology: Applications to Health and Social Renewal

We introduce the topic of Indian/US collaboration in studying religion and spirituality (R/S), providing both historical and philosophical context. A fully in-depth and comprehensive study of R/S will require taking into account three potential types and sources of knowledge: (1) theoretically and intellectually oriented knowledge as exemplified by William James; (2) empirically oriented knowledge as exemplified by Gordon Allport; and (3) experience- and realization-derived knowledge based on reports from eminent spiritual figures. We sketch the distinct but mutually informative challenges of clinical and epistemic integration. We suggest several topics for future collaboration, arguing that the most comprehensive study of R/S will require combining the western attention to empirical knowledge with the Indian psychology movement’s attention to realization-derived knowledge. Suggested topics include processes of learning from spiritual exemplars and teachers; health effects from engagement in Hindu or other Indian religious practice; psychological and health effects of specific spiritual practices; the importance and influence of the focus used in meditation; the effects of japam, Ramnam, or similar repeated short prayers; how diverse spiritual practices affect mindfulness; and the nature and means of fostering skills for living in a religiously plural society.     

Indian Spirituality: How Relevant is Pargament’s Framework?

The psychology of religion and spirituality is a topic of increasing interest in India as well as in the West. An internationally influential framework for defining religion and spirituality has been developed by US psychologist Kenneth Pargament, who conceptualizes spirituality and religion as search processes related to sacred realities. Pargament’s framework has been found to resonate across multiple cultures and has guided and informed empirical research in Jewish, Christian, and Muslim populations. The present paper argues that Pargament’s framework can also coherently resonate with Hinduism and other indigenous Indian religious beliefs and practices. We conclude that future studies of religion and spirituality in Indian contexts may benefit by framing their investigations with reference to Pargament’s approach. Such framing need not be uncritical and would help bring Indian psychology of spirituality/religion in closer contact with psychology of spirituality/religion in other parts of the world, benefiting both India and the worldwide psychology of religion and spirituality.     

Eknath Easwaran’s Mantram and Passage Meditation as Applied Indian Psychology: Psycho-Spiritual and Health Effects

We review the life and legacy of Eknath Easwaran (1910–1999) from the perspective of modern and Indian Psychology. A Kerala-born professor of English literature, Easwaran in 1959 travelled to the USA where he taught a system of eight spiritual practices known as passage meditation (PM). Its characteristic features include its meditative focus on memorized inspirational passages and using mantram repetition as a primarily “portable” practice throughout the day. The PM method is distinctive in emphasizing the principle, otherwise neglected in the modern psychology of meditation, that “we become what we meditate on”—a principle that possesses a basis in traditional Indian sources that include the Vedas, Puranas, Adi ?a?kara, and Ramakrishna Paramahamsa. Two major programs of empirical research have evaluated Easwaran’s practices, each publishing multiple randomized controlled trials. We summarize findings from (i) studies of the full PM program, and (ii) studies of the Mantram Repetition Program (MRP), based on three of the eight PM points. Randomized evidence links each program to reduced stress, improved mental health, improved mindfulness, and increases in various spiritual measures. We describe ways that PM/MRP empirical research has reflected Indian Psychology perspectives, and suggest that Easwaran’s legacy enriches Indian Psychology with added value in at least three ways: emphasizing the importance of the choice of meditative focus, offering universally framed support for devotional (bhakti) orientations to spirituality, and supplying tools for improving how spiritual diversity is addressed in modern institutions such as health care, schools, and other organizations.     

The generalized optic acceleration cancellation theory of catching

The generalized optic acceleration cancellation (GOAC) theory of catching proposes that the path of a fielder running to catch a ball is determined by the attempt to satisfy 2 independent constraints. The 1st is to keep the angle of elevation of gaze to the ball increasing at a decreasing rate. The 2nd is to control the rate of horizontal rotation necessary to maintain fixation on the ball. Depending on the lateral velocity of the ball relative to the fielder, this rate may be zero or constant at a negative or positive value. The authors show that a simulated fielder implementing the GOAC strategy follows a path indistinguishable from that of real fielders running to catch balls thrown on the same trajectories.     

Discrepant Data and Improbable Results: An Examination of Vohs,Mead, and Goode (2006)

A highly cited article by Vohs, Mead, and Goode (2006) reported several experiments in which an incidental reminder of money produced large effects on subsequent behaviors unrelated to money. We attempted 2 high-powered direct replications of the first experiment, which found that money-primed subjects worked on a puzzle nearly twice as long as controls before quitting. The replication studies showed no evidence of money priming. Moreover, 25% of the subjects in our studies solved the puzzle correctly or incorrectly, whereas none reportedly did so in the original study. We also list anomalies in the reported results of the original study.
