Universal sex differences in the desire for sexual variety: tests from 52 nations, 6 continents,and 13 islands

Evolutionary psychologists have hypothesized that men and women possess both long-term and short-term mating strategies, with men's short-term strategy differentially rooted in the desire for sexual variety. In this article, findings from a cross-cultural survey of 16,288 people across 10 major world regions (including North America, South America, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, South/Southeast Asia, and East Asia) demonstrate that sex differences in the desire for sexual variety are culturally universal throughout these world regions. Sex differences were evident regardless of whether mean, median, distributional, or categorical indexes of sexual differentiation were evaluated. Sex differences were evident regardless of the measures used to evaluate them. Among contemporary theories of human mating, pluralistic approaches that hypothesize sex differences in the evolved design of short-term mating provide the most compelling account of these robust empirical findings.     

The preparation of counsellors in Europe: Possible solutions for an impossible task?

The growth of counselling and psychotherapy presents trainers in Europe with significant opportunities. But these need to take account of human development over the millenia, harnessing ancient psychology to the resolution of contemporary problems. In particular, there is a need for contextual counselling, beating practice in culture. Extrapolating from UK data, a minimum practitioner requirement for Europe could be 50,000-75,000 counsellors. With only minimal training programmes in many European countries, meeting the seven core criteria of training seems impossible. One possible solution is to cluster people with limited training around a high-standard professional counsellor—a system used in the UK for situation-specific counselling. A number of European states are now seeking to develop a counselling capability. Training for this should break new ground by learning from older systems but also being unafraid to adopt novel solutions.     

A Comparison of Least-to-Most Prompts and Progressive Time Delay on the Disruptive Behavior of Students with Autism

We compared the effects of two instructional strategies on the frequency of errors and episodes of disruptive behavior of 4 students with autism. In Phase I, easy and difficult tasks were presented to determine whether the tasks were associated with differential rates of disruptive behavior. Phase II compared the effects of a least-to-most prompting procedure (LTM) to a progressive time delay procedure (PTD) on errors and disruptive behavior when difficult tasks were presented. Observers sequentially recorded instructor instructions, response prompts, prompts for appropriate sitting, and feedback statements; and student disruptive, correct, error, and no responses during 1:1 sessions. Results showed PTD produced fewer errors than LTM for all 4 students, and lower rates of disruptive behavior for 2 students. When PTD was implemented as the final phase with 2 of the students, rates of disruptive behavior associated with the task previously taught with LTM immediately decreased. Conditional probability statements indicated that disruptive behavior occurred infrequently with all 4 students when effective response prompts were used.     

Case study: Reinforcement control of severe aggression exhibited by a child with autism in a family home

This clinical case study describes in-home treatment of severe aggression and tantrum behavior exhibited by an 11 -year-old child with autism, using methods of differential reinforcement comparable to those of a case study by Luiselli (1990). No significant reductions in problem conduct occurred when a parent implemented differential reinforcement of other behavior (DRO) in conjunction with publicly posted ‘good behavior rules,’ physical management training, and redirection to relaxation. Control was established when the child was reinforced for compliance with task demands in conjunction with extinction, implemented directly by professional support staff working in the home. Despite demonstrable parental consistency, systematic training, and fading of supports, results were not maintained at follow-up. The generality of differential reinforcement as a practical intervention for severe aggression in family homes is questioned.     

Koan Zen and Wittgenstein's Only Correct Method in Philosophy

Koan Zen is a philosophical practice that bears a strong family resemblance to Wittgenstein's approach to philosophy. In this paper I hope to show that this resemblance is especially evident when we compare the Zen method of koan with Wittgenstein's suggestion, towards the end of his Tractatus, about what would constitute the only correct method in philosophy. Both koan Zen and Wittgenstein's method set limits to the reach of philosophical discourse. Each rules metaphysical speculation out of bounds. Neither, however, represents a rejection of the metaphysical. Where Wittgenstein enjoins silence in the face of the unsayable, a silence that allows the metaphysical to show itself, koan Zen calls for concrete demonstrations of that which cannot be captured in rational discourse. I attempt to illustrate this through discussion of a number of koans that serve as reminders that the philosopher (and Zen master) should say nothing except what can be said.     

Parentification and Alcohol Use: Conditional Effects of Religious Service Attendance

This study tested a model of the relation between parentification and alcohol use through differentiation of self (DoS), with religious service attendance as a moderator. Results provided mixed support for the model. Perceived unfair parentification was associated with decreased DoS, and lowered DoS corresponded to increased alcohol use. Religious service attendance moderated the association between increased perceived unfairness and increased alcohol use. Implications for practice focused on assessing perceived unfairness and integrating clients’ religiousness.     

Identifying mediators of training effects on performance-related psychobiosocial states: A single-case observational study in an elite female triathlete

ObjectivesRelationships between training load, psychobiosocial (PBS) states and performance are dynamic and individual-specific. The nature of these relationships can be investigated using a combination of dynamic linear models (DLMs) and mediating variable analysis, potentially assisting applied sports psychologists in planning and monitoring of individual elite athletes’ intervention programmes.DesignWe illustrate this approach by examining the relationships of training loads with a performance-related state (‘self-efficacy’) and the role of potential mediating PBS variables (‘fatigue/lack of energy’ and ‘being in shape’) in explaining these relationships in an elite triathlete across time.MethodSelf-reports of PBS states (twice weekly) and training data were collected over 137 days. Using DLMs and mediating variable analysis, direct (unmediated) and indirect (mediated) short-term associations of training load with ‘self-efficacy’ were examined.ResultsIn this triathlete, we found evidence for positive effects of training on ‘self-efficacy’, which were partly explained by feelings of ‘being in shape’ and suppressed by feelings of ‘fatigue/lack of energy’. Changes in the relationship between lagged training load and ‘fatigue/lack of energy’ were observed across time and were particularly pronounced in temporal proximity of an injury.ConclusionStrengths of the presented approach are its dynamic nature enabling the observation of changes occurring over time, use of statistical inference rather than visual data interpretation, and quantification of mediating effects to identify potential pathways of intervention. Additionally, the DLM method can identify complex nonlinear associations by examining correspondence between changes in levels of predictors and changes in magnitude and direction of predictor-outcome associations.
