Professional Development in Sport Psychology: Relating Learning Experiences to Learning Outcomes

To enhance the training of sport psychology consultants, it is important to know which learning experiences are useful for which components of professional development. We interviewed 15 novice consultants on their learning experiences related to 13 different topics. Traditional learning experiences (e.g., courses, teachers) were related to the development of practical know-how. Learning from others (e.g., peers, colleagues) was related to professional development (i.e., dealing with issues, challenges, and dilemmas that occur in sport psychology practice). Practical experience and reflective activities were related to both know-how and professional development. These results can be used to shape effective sport psychology education.     

Reduced constituent category application in surprising combinations

In a previous study (R. R. C. Hutter & R. J. Crisp, 2005), the authors suggested that one way in which perceivers resolve the dilemma of shared membership of incongruent category combinations is by generating emergent attributes. However, the authors also found evidence that a corresponding process of reduced constituent facilitation occurs. In the present research, the authors aimed to isolate this phenomenon using a response-time methodology. Participants were exposed to subliminal unsurprising or surprising gender-occupation category-combination primes. The authors observed facilitation in overall response times on a subsequent lexical decision task to constituent attributes when the combination primed was unsurprising compared with surprising, but only for female and not for male combinations. The authors suggest that perceivers reduce their application of constituent attributes when processing surprising versus unsurprising combinations.     

Reward tampering problems and solutions in reinforcement learning: a causal influence diagram perspective

Can humans get arbitrarily capable reinforcement learning (RL) agents to do their bidding? Or will sufficiently capable RL agents always find ways to bypass their intended objectives by shortcutting their reward signal? This question impacts how far RL can be scaled, and whether alternative paradigms must be developed in order to build safe artificial general intelligence. In this paper, we study when an RL agent has an instrumental goal to tamper with its reward process, and describe design principles that prevent instrumental goals for two different types of reward tampering (reward function tampering and RF-input tampering). Combined, the design principles can prevent reward tampering from being an instrumental goal. The analysis benefits from causal influence diagrams to provide intuitive yet precise formalizations.

     

Security of multi-agent systems: A case study on comparison shopping

The multi-agent-systems paradigm is becoming more and more popular as a basis for realizing net-based solutions. This development is accompanied by an increasing relevance of security issues. For instance, the potential loss of privacy and other assets is a major concern for, both merchants and customers, in Internet-based commerce and, without being properly addressed, such very legitimate concerns hamper the growth of e-commerce.This article uses a comparison-shopping scenario to introduce a general methodology for formally verifying the security of multi-agent systems. Following the approach of possibilistic information flow security, the flow of information between and within agents is restricted in order to ensure that secrets will not be disclosed to unauthorized meddlers. The security requirements for the overall system are then decomposed into requirements for the individual agents that can be verified independently from each other. Exploiting the modular structure of a multi-agent system considerably reduces the complexity of the overall security analysis. The techniques for decomposing security requirements, for verifying individual agents, and for deriving global security guarantees for the entire system from locally verified properties are all generic in the sense that they apply also to many other systems and security requirements than the ones that appear in the example scenario.     

Resolving conflicting social categories: the role of age-related executive ability

We investigated the effect of age-related decline in executive ability on the application of emergent features to incongruent social category conjunctions (e.g., male midwife). When forming an impression of an incongruent conjunction, older adults used more emergent attributes (attributes associated exclusively with the category conjunction and not the constituents), relative to younger adults. Moreover, this relationship was mediated by a reduction in inhibitory ability (measured using a Stroop task) and processing speed (measured using a Digit Symbol Substitution Test, DSST). These findings are consistent with the notion that executive ability is pivotal in understanding social functioning in older adults. We discuss the implications of these findings for the continuing development of models outlining the processes and stages involved in perceiving social category conjunctions.     

INTEGRAL LEADERSHIP FOR THE 21 st CENTURY

Current leadership theories and business models—built around modernist assumptions about winners and losers, power and control, and local rather than global interactions—are decades out of date with what is needed to lead postindustrial and postmodern enterprises. This article calls for a collaborative and socially intelligent theory for leadership development based on Integral Science. This theory incorporates and unifies appropriate elements of current leadership research for a postmodern knowledge economy and seeks answers to questions still unanswered.
