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.     

‘Our periodic table of hate’: The archive of 1984 Punjab in Jaspreet Singh’s Helium

Highly critical of the Indian government's cover up of the 1984 Sikh pogroms, Indian-Canadian author Jaspreet Singh offers a scathing expose of the anti-Sikh violence in his 2013 novel Helium. Singh experienced first-hand the ‘holocaust’ of 1984 in Delhi, and as a diasporic Indian since 1990, he is also intimately familiar with the burdens of postmemory among Sikhs in the west, many of whom sought asylum abroad in the wake of 1984. Influenced by Primo Levi and W.G. Sebald, Singh constructs a multi-generic ‘archive’ of the crimes of 1984 in Helium, which articulates the lingering trauma of the Sikhs and challenges the image of a unified, multiculturalist, secular-humanist postcolonial Indian state. Drawing on exhaustive research, Helium is a hybrid of fiction, survivor and relief worker testimonials, photographs, drawings, documentary, thriller, and inter-textual narrative—because the horror of 1984 cannot be recounted through a single medium or genre or voice. In considering its archival form and political intent, my article establishes Helium as a bold, ethical attempt to record the anti-Sikh violence of 1984 in order to bring justice to both the dead and the survivors.     

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.     

A Logical Analysis of Monty Hall and Sleeping Beauty

Hintikka and Sandu’s independence-friendly (IF) logic is a conservative extension of first-order logic that allows one to consider semantic games with imperfect information. In the present article, we first show how several variants of the Monty Hall problem can be modeled as semantic games for IF sentences. In the process, we extend IF logic to include semantic games with chance moves and dub this extension stochastic IF logic. Finally, we use stochastic IF logic to analyze the Sleeping Beauty problem, leading to the conclusion that the thirders are correct while identifying the main error in the halfers’ argument.     

Mimicry and Investigative Interviewing: Using Deliberate Mimicry to Elicit Information and Cues to Deceit

We examined the effect of deliberate mimicry on eliciting (accurate) information and cues to deceit. Mimicry is considered to facilitate cooperation and compliance in truth tellers, whereas liars are constrained to provide detail. We therefore expected truth tellers to be more detailed than liars, particularly after being mimicked. A total of 165 participants told the truth or lied about a meeting they attended. During the interview, an interviewer mimicked half of the participants. Truth tellers were more detailed than liars, but only in the ‘mimicry present’ condition. Truth tellers also gave more accurate units of information than liars, and the difference was most pronounced in the ‘mimicry present’ condition. Mimicry as a tool for eliciting information and cues to deceit fits well with the emerging ‘interviewing to detect deception’ literature, particularly in the ‘encouraging interviewees to say more’ approach.

Action specificity increases anticipatory performance and the expert advantage in natural interceptive tasks

The relationship between perception-action coupling and anticipatory skill in an interceptive task was examined using an in-situ temporal occlusion paradigm. Skilled and novice cricket batsmen were required to predict the direction of balls bowled towards them under four counterbalanced response conditions of increasing perception-action coupling: (i) verbal, (ii) lower-body movement only, (iii) full-body movement (no bat), and (iv) full-body movement with bat (i.e., the usual batting response). Skilled but not novice anticipation was found to improve as a function of coupling when responses were based on either no ball-flight, or early ball-flight information, with a response requiring even the lowest degree of body movement found to enhance anticipation when compared to a verbal prediction. Most importantly, a full-body movement using a bat elicited greater anticipation than an equivalent movement with no bat. This result highlights the important role that the requirement and/or opportunity to make bat-ball interception may play in eliciting skill differences for anticipation. Results verify the importance of using experimental conditions and task demands that closely reflect the natural performance environment in order to reveal the full nature of the expert advantage.     

Financial stress, attitudes toward money, and scores on a Dream Inventory

During stock market losses in 2009 and high unemployment, ratings on the KJP Dream Inventory were correlated with factors of the Money Attitude Scale and items on the Contemporary Financial Stress Inventory for 71 graduate students in Counseling Psychology and Education. Correlations were significant for Retention on the Money Attitude Scale with Dissociative Avoidance (-.31), Dreams of falling (.26), Risk-taking in dreams (.24), and Dreaming of being chased (.28). Also, ratings for the Money Attitude Scale of Distrust correlated with Discontentedness in dreams (.33) and Dreams of being chased (.26), Repetitive trauma (.33), Nightmares (.30), and Recurring nightmares (.35). Concern about retention in graduate school due to finances correlated with recalled frequencies of nightmares (.27) and dreams of flying (.25).
