Empirical comparison of Markov and quantum models of decision making

There are at least two general theories for building probabilistic-dynamical systems: one is Markov theory and another is quantum theory. These two mathematical frameworks share many fundamental ideas, but they also differ in some key properties. On the one hand, Markov theory obeys the law of total probability, but quantum theory does not; on the other hand, quantum theory obeys the doubly stochastic law, but Markov theory does not. Therefore, the decision about whether to use a Markov or a quantum system depends on which of these laws are empirically obeyed in an application. This article derives two general methods for testing these theories that are parameter free, and presents a new experimental test. The article concludes with a review of experimental findings from cognitive psychology that evaluate these two properties.     

A Trio of Concerns

ABSTRACT— This essay assesses the two most significant changes in psychology over the past century: the attempt to localize psychological phenomena in restricted brain sites and the search for genetic contributions to behavior and psychopathology. Although there are advantages to these new developments, they are accompanied by some questionable assumptions. Because the investigators in these domains often relate variation in their biological measures to variation in personality traits evaluated with questionnaires, an analysis of the unique properties of the verbal-report questionnaires is presented. It is suggested that future research on human personality should try to combine semantic reports with behaviors and biological data in order to arrive at more fruitful constructs.     

Varieties of Religious Naturalism

This article opens with two generic definitions of religious naturalism in general: one by Jerome Stone and one by Rem Edwards used by Charley Hardwick. Two boundary issues, humanism and process theology, are discussed. A brief sketch of my own "minimalist" and pluralist version of religious naturalism follows. Finally, several issues that are, or should be, faced by religious naturalists are explored.     

The myth of open concepts: Meehl’s analysis of construct meaning versus black box essentialism

Two views of theoretical concepts in psychology are compared. Meehl’s “open concept” account holds that theoretical concepts are implicitly defined by theories but that empirical criteria can be changed over time (e.g., added or dropped, weightings changed, exchanged for theoretical reductions). This account confuses concepts and theories, does not reflect how diagnostic concepts actually work in medicine and psychology, leads to theory incommensurability, and is unclear about when concepts are the same or different. I propose that an alternative “black box essentialist” account of theoretical concepts, drawn from recent philosophical work on natural kind concepts, better explains how we manage to refer to the same construct even as our theories and criteria change. One implication is that Meehl is incorrect to claim that a reason for psychology’s lack of progress is that its concepts are inherently different from those in the hard sciences.     

Staff Practices and Social Skill Outcomes in a Sport-Based Youth Program

Staff are key contributors to quality sport-based youth programming. Specific practices leading to positive youth outcomes warrant further investigation. This study examined social skill outcomes resulting from participation in a sport-based youth program, LiFEsports. In addition, relationships among emotional and autonomy supportive staff practices and outcomes were examined. Results pointed to the value of sport-based youth programs for promoting self-control among youth from vulnerable backgrounds and indicated that youth-perceived emotional and autonomy supportive staff practices predicted improvements in perceived self-control but not perceived externalizing behaviors.     

The Influence of Spiritually-based Learning Opportunities on Personal Faith and Denominational Loyalty in Seventh-Day Adventist Academies

This study examined how Bible teachers, involvement in leadership in school-wide spiritual activities, and personal school-sponsored spiritual activities were related to students’ relationship with God and their denominational loyalty. Data were obtained from seniors in 19 Seventh-day Adventist academies. Students’ intention to remain in the Seventh-day Adventist church after they finish high school or leave their parents’ home (denominational loyalty) was explained by their involvement and leadership in school-sponsored spiritual activities and the influence of their Bible teacher. However, the effect of these variables on denominational loyalty was primarily due to the extent that they affected the students’ relationship with God.     

The courage of the group therapist

This report strives to legitimize for the field of psychodynamic group therapy the reflection on and study of courage. The authors surveyed group therapy leaders, asking them to describe courageous moments in their own group practice, and then explored the common themes arising in these examples, including openly confronting their mistakes, facing their own and group members' anger, and dealing with unexpected moments in group sessions. Attending to courageous leader moments-and the feelings of hope and pride that they engender-help to neutralize the negative emotions that group leaders are constantly invited to contain. Paradoxically, accessing courageous moments can also evoke feelings of shame in the leader. If we are to require ourselves to embrace the sometimes terrifying challenge of journeying into the unknown with our patients, we must learn to be honest not just about our mistakes and our weaknesses, but also about our successes and our strengths.     

Motor and cognitive proficiency of learning disabled and normal children

Motor and cognitive skills of learning disabled (N = 32) and normal (N = 32) boys were compared on the Modified Lincoln-Oseretsky Motor Development Scale and on the WISC-R Vocabulary and Block Design subtests. Eight learning disabled and eight normal boys were tested at four age levels from 8 to 11 years. All boys were of normal intelligence. Motor and cognitive skills of the learning disabled boys were significantly below those of the normal boys and below those of the normative group. Chronological age was not a significant factor in relationship to either motor or cognitive skills. Intercorrelations indicated that in the learning disabled group Block Design, but not Vocabulary, was significantly related to motor scores at the 8- and 9-year ages. These results suggest that a common factor relating to perceptual-motor coordination and efficiency may be involved on the Lincoln-Oseretsky and Block Design subtest for young learning disabled children but not for older learning disabled children or for normal children.
