A Generalized Speed–Accuracy Response Model for Dichotomous Items

We propose a generalization of the speed–accuracy response model (SARM) introduced by Maris and van der Maas (Psychometrika 77:615–633, 2012). In these models, the scores that result from a scoring rule that incorporates both the speed and accuracy of item responses are modeled. Our generalization is similar to that of the one-parameter logistic (or Rasch) model to the two-parameter logistic (or Birnbaum) model in item response theory. An expectation–maximization (EM) algorithm for estimating model parameters and standard errors was developed. Furthermore, methods to assess model fit are provided in the form of generalized residuals for item score functions and saddlepoint approximations to the density of the sum score. The presented methods were evaluated in a small simulation study, the results of which indicated good parameter recovery and reasonable type I error rates for the residuals. Finally, the methods were applied to two real data sets. It was found that the two-parameter SARM showed improved fit compared to the one-parameter SARM in both data sets.     

Does Teaching Problem-Solving Skills Matter? An Evaluation of Problem-Solving Skills Training for the Treatment of Social and Behavioral Problems in Children

Problem-solving skills training (PSST) has been proposed as a potentially effective addition to behavioral parent training (PT). However, it is not clear whether PSST specifically increases the benefits provided by PT. In this study, PT + PSST was compared to PT + nondirective therapy in a sample of 26 families. All parents received PT. Following this, children received PSST or nondirective therapy. Outcomes included measures of child behavior problems, social skills, and parent stress at posttherapy and a 6-week follow-up. Children in both groups improved over time with few differences between groups.     

Development and validation of the Intervention Skills Profile–Skills: A brief measure of student social-emotional and academic enabling skills

The purpose of this study was to support the development and initial validation of the Intervention Selection Profile (ISP)–Skills, a brief 14-item teacher rating scale intended to inform the selection and delivery of instructional interventions at Tier 2. Teacher participants (n = 196) rated five students from their classroom across four measures (total student n = 877). These measures included the ISP-Skills and three criterion tools: Social Skills Improvement System (SSIS), Devereux Student Strengths Assessment (DESSA), and Academic Competence Evaluation Scales (ACES). Diagnostic classification modeling (DCM) suggested an expert-created Q-matrix, which specified relations between ISP-Skills items and hypothesized latent attributes, provided good fit to item data. DCM also indicated ISP-Skills items functioned as intended, with the magnitude of item ratings corresponding to the model-implied probability of attribute mastery. DCM was then used to generate skill profiles for each student, which included scores representing the probability of students mastering each of eight skills. Correlational analyses revealed large convergent relations between ISP-Skills probability scores and theoretically-aligned subscales from the criterion measures. Discriminant validity was not supported, as ISP-Skills scores were also highly related to all other criterion subscales. Receiver operating characteristic (ROC) curve analyses informed the selection of cut scores from each ISP-Skills scale. Review of classification accuracy statistics associated with these cut scores (e.g., sensitivity and specificity) suggested they reliably differentiated students with below average, average, and above average skills. Implications for practice and directions for future research are discussed, including those related to the examination of ISP-Skills treatment utility.     

Teaching the Bible in the schools of the Labor and the Kibbutz Movements, 1921–1953

How the challenge of teaching the Bible was met by educators who were members of the Kibbutz and Labor movements during the years before the establishment of the Israeli State is the subject of the following essay. Years ago, Jacobus Schoneveld, (1976), recently followed by Asher Shkedi (2004) proposed dividing educators of the Labor and Kibbutz movements into three types: those who wished to stress “national reconstruction,” those directed toward teaching a “universal humanism” and those seeking to awaken “moral dialogue” and achieve “personal growth.” In fact, such clear-cut lines of demarcation did not exist. The goals were these, but approaches themselves were always mixed. One distinguishes educational goals better by a more simple division into the questions of what is to be taught (religious versus Secular materials) and through which ancillary disciplines. Doing so has the virtue of highlighting how these educators were animated by their quest after how best to teach Biblical morality with the aim of “shaping” the student or achieving “emulation,” especially by generating a “dialogue” between the pupil and the biblical text, leading to “personal growth.” These emphases tell us much about the pre-State educational mentality and pedagogical ideals.     

Selection for Some,Facilitation for Others? Self-Control Theory and the Gang–Violence Relationship

Although self-control theory has been thought to be entirely consistent with the gang selection model, key theoretical predictions of the general theory imply gang selection effects for those with lower self-control and gang facilitation effects for those with higher self-control. This new hypothesis is tested among a large sample of jail inmates. Results indicate that self-control did not render the gang–violence relationship spurious for the sample as a whole. Gang membership had a significantly greater impact on violent crime among those with very high self-control, but there were still statistically significant gang facilitation effects for the other three self-control groups.     

Performance of Faller and Nonfaller Older Adults on a Motor–Motor Interference Task

Typically, falls in older adults occur when 2 tasks are performed simultaneously, due to the increased motor demand required to maintain stability and attention to perform the other task. The authors' purpose was to investigate walking while grasping, transporting, and placing a dowel on a predetermined target while manipulating difficulty levels of the manual task. Faller and nonfaller older adults performed a walking block (manual tasks combined with gait) and a stationary block (upright stance combined with manual tasks). The manual task involved grasping, transporting, and placing the dowel over a target. The results showed that fallers underperformed when compared with nonfallers in the task of placing the dowel over the target. The main difference observed between the groups was found in the condition that required allocation of attention between tasks and greater accuracy in the final placement of the object. Fallers showed gait stability similar to the nonfallers, but fallers were less accurate than nonfallers in the object placement task, especially for the highest level of difficulty. Thus, fallers seem to use a stability-first strategy. Fallers had problems in executing the manual tasks, which suggests a more global change in motor behavior rather than specific changes to balance control.     

The Standard-Relational Theory of ‘Ought’ and the Oughtistic Theory of Reasons

In the context of his highly influential defence of compatibilism, P. F. Strawson 1962 Strawson, P. F. 1962. “Freedom and Resentment, in Fischer and Ravizza [1993]”. 45–66.  [Google Scholar] introduced the terms ‘reactive attitude’ and ‘objective attitude’ to the free-will lexicon. He argued, in effect, that relinquishing such reactive attitudes as resentment and moral indignation isn't a real possibility for us, since doing so would commit us to exclusive objectivity, a stance incompatible with ordinary interpersonal relationships. While most commentators have challenged Strawson's link between personal relationships and the reactive attitudes, Tamler Sommers 2007 Sommers, Tamler. 2007. The Objective Attitude. Philosophical Quarterly, 57/3: 321–41.  [Google Scholar] has taken up Strawson's claim that exclusive objectivity would preclude meaningful relationships. Here I set out a defence of this claim by identifying a kind of interpersonal caring that is plausibly both required for such relationships and excluded by the objective attitude. I then argue that this defence helps to support Strawson's more controversial claim about personal relationships and the reactive attitudes.     

Accuracy and performance of the state-based Φ and liveliness measures of information integration

A number of people have suggested that there is a link between information integration and consciousness, and a number of algorithms for calculating information integration have been put forward. The most recent of these is Balduzzi and Tononi’s state-based Φ algorithm, which has factorial dependencies that severely limit the number of neurons that can be analyzed. To address this issue an alternative state-based measure known as liveliness has been developed, which uses the causal relationships between neurons to identify the areas of maximum information integration. This paper outlines the state-based Φ and liveliness algorithms and sets out a number of test networks that were used to compare their accuracy and performance. The results show that liveliness is a reasonable approximation to state-based Φ for some network topologies, and it has a much more scalable performance than state-based Φ.     

Theory for the mechanism of action of “miracle fruit”

The action of miracle fruit in changing the quality of a sour stimulus to that of sweet is hypothesized as being caused by blocking of the sour receptor sites. It is assumed, according to a new theory that holds that proton acceptors are sweet-evoking, that many sour stimuli are also simultaneously stimuli for the sweet receptors. However, the resulting sweet information is strongly inhibited by the sour system, so that sweet is not reported.     

Haag’s Theorem and its Implications for the Foundations of Quantum Field Theory

Although the philosophical literature on the foundations of quantum field theory recognizes the importance of Haag’s theorem, it does not provide a clear discussion of the meaning of this theorem. The goal of this paper is to make up for this deficit. In particular, it aims to set out the implications of Haag’s theorem for scattering theory, the interaction picture, the use of non-Fock representations in describing interacting fields, and the choice among the plethora of the unitarily inequivalent representations of the canonical commutation relations for free and interacting fields.     

The Effect of Parents’ Literacy Skills and Children’s Preliteracy Skills on the Risk of Dyslexia

The combination of investigating child and family characteristics sheds light on the constellation of risk factors that can ultimately lead to dyslexia. This family-risk study examines plausible preschool risk factors and their specificity. Participants (N?=?196, 42 % girls) included familial risk (FR) children with and without dyslexia in Grade 3 and controls. First, we found impairments in phonological awareness, rapid naming, and letter knowledge in FR kindergartners with later dyslexia, and mild phonological-awareness deficits in FR kindergartners without subsequent dyslexia. These skills were better predictors of reading than arithmetic, except for rapid naming. Second, the literacy environment at home was comparable among groups. Third, having a dyslexic parent and literacy abilities of the non-dyslexic parent related to offspring risk of dyslexia. Parental literacy abilities might be viewed as indicators of offspring’s liability for literacy difficulties, since parents provide offspring with genetic and environmental endowment. We propose an intergenerational multiple deficit model in which both parents confer cognitive risks.     

Which Time for Eschatology? Relativity Theory,Local and Cosmic Times,and the End of the Universe

The aim of this article is to formulate the theological notions of the end and fulfilment of the universe before the background of relativity theory and cosmology, in particular the lack of a global passage of time. It argues that the “arrow” of time is a local phenomenon, linked essentially to recording objects. On this basis, it makes the case that the notions of a common end of all local times and of a final, timeless state of the universe are viable independently of a global direction of time.     

Where To From Here for the Psychology of Social Change? Future Directions for Theory and Practice

For a vibrant and viable psychology of social change it is necessary to examine its place and contribution to the societal processes it seeks to understand, explain, and (potentially) affect. In this article, we first consider the impact that research and theorizing on social change (should) have and related issues of how we communicate about our work (and to whom) and dilemmas around researchers being active participants in the change process. Second, we consider emerging trends in the field and comment on meta‐theoretical and “meta‐methodological” issues in going forward, including the interaction between individual and society, having theoretical models of the person that allow us to account for such an interaction, as well as rethinking our methodology and ways of “doing” psychology to better reflect people's experiences of mobilization and participation. In line with the proposed rethinking of our theories and methods, the final section introduces a new paradigm for investigating the nexus of social change and leadership dynamics. The overall aim of the article is to reflect on key questions and dilemmas facing the field and provide some starting points for debating and shaping its future.     

A Review of “Relational Competence Theory: Research and Mental Health Applications”

Within the Couple and Family Therapy literature, there are few articles directly linking theory to treatment within the lesbian community. Utilizing contextual theory, the author presents a gay affirmative therapeutic approach to work with lesbian couples. The fundamental concepts of contextual therapy are uniquely suited for work with lesbian clients; particularly the four dimensions of individual psychology, relational ethics, systemic interaction, and facts. A case study is presented to highlight this therapeutic process. This article is one step in a larger systemic change related to the challenge of adapting theoretical methodology and gathering evidence for effective treatment of marginalized groups.     

Psychological Skills and “the Paras”: The Indirect Effects of Psychological Skills on Endurance

We examined the indirect effects of basic psychological skills (PS) on military endurance through enhanced advanced PS while controlling for fitness. British Army recruits (n = 159) participated in three endurance events for Parachute Regiment selection and completed an adapted Test of Performance Strategies questionnaire (Hardy et al., 2010 Hardy, L., Roberts, R., Thomas, P. R., &; Murphy, S. M. (2010). Test of performance strategies (TOPS): Instrument refinement using confirmatory factor analysis. Psychology of Sport and Exercise, 11, 27–35. doi:10.1016/j.psychsport.2009.04.007[Crossref], [Web of Science ®] , [Google Scholar]). Following confirmatory factor analyses, the multiple mediation regression analyses using PROCESS (Hayes, 2013 Hayes, A.F. (2013). Introduction to mediation, moderation and conditional process analysis: A regression-based approach. New York, NY: Guilford Press. [Google Scholar]) suggested that goal setting, imagery and relaxation all had positive indirect effects on endurance via activation, with goal setting also impacting on endurance via negative thinking. These data provide some support for basic PS influencing endurance via advanced PS.     

Speed of processing explains the picture–word asymmetry in conditional naming

In this study, we investigated picture (Experiments 1 and 2) and word (Experiments 3 and 4) processing using different tasks. In Experiments 1 and 3, easy and difficult conditional naming tasks were compared to a free naming task. In Experiments 2 and 4, easy and difficult conditional naming tasks were compared to easy and difficult manual forced-choice semantic decision tasks. For pictures, we showed that a difficult semantic categorization determined a cost for the conditional naming with respect to the free naming (Experiment 1). Also, we found that the difference in RTs between the easy and difficult conditional naming tasks was much smaller than the difference between the easy and difficult forced-choice semantic decision tasks (Experiment 2). For words, results showed that free reading was faster than easy conditional reading, which in turn was faster than difficult conditional reading (Experiment 3). An analogous pattern of results was obtained when the easy and difficult conditional reading tasks were compared to the easy and difficult forced-choice semantic decision tasks (Experiment 4). Globally, the results showed that whether a cost is observed or not depends upon the relative timing of the classification and name retrieval processes. A theoretical framework has been proposed.
