Teaching the Bible along the Devotional/Academic Faultline: An Incarnational Approach to the Quarrel between Love and Knowledge

Abstract. There seem to be two irreconcilable approaches to reading the Bible, and these often collide in an undergraduate's first college class in religion. Students from a devotional background find the scholarly approach a disappointment compared with their preferred way of reading. Yet upon closer examination the limits of an exclusively devotional way or an exclusively academic way soon become apparent. A way beyond this impasse is described as an incarnational approach, which seeks to honor the integrity of the literary, cultural, and historical features of the Bible while also taking seriously the personal faith of both student and instructor. This strategy is not original of course, but is a case study of a way in which the Christian tradition may address the quarrel between two competing ways of reading and turn it into a conversation.     

The Relative Effects of Abstract Versus Concrete Processing on Proactivity in Depression

Low levels of proactivity are characteristic of individuals with depression. Two studies were conducted to compare the relative effects of abstract versus concrete processing on proactivity in high dysphoric individuals. In Study 1, participants read information about an upcoming research study and were then randomly allocated to a writing task that induced them to think about participating in that study in either an abstract (e.g., Why you would participate in the study?; n = 25) or concrete (e.g., How you will participate in the study?; n = 25) way. Participants were then asked to indicate whether they would sign up to the study. As expected, more participants indicated that they would take part in the study in the concrete condition (76%) than in the abstract condition (36%). In Study 2, high dysphoric participants were asked to identify their ideal part-time job and were then randomly allocated to a writing task that induced them to think about applying for the job in an abstract (n = 26) or concrete (n = 25) way. There was no difference between conditions in self-reported intentions of proactivity. However, significantly more participants in the concrete condition opted to look at an employment assistance website and returned to the lab to collect a job application package. Overall, these findings suggest that abstract processing could contribute to low levels of proactivity in depression, and that facilitating the use of concrete processing could help to alleviate this problem. Our results also point to the need for greater conceptual clarification of the distinction between concrete processing about proactive behavior and implementation intentions (identifying specific steps for completing an action/goal).     

Familiarity breeds attraction: effects of exposure on the attractiveness of typical and distinctive faces

Several studies have shown that facial attractiveness is positively correlated with both familiarity and typicality. Here we manipulated the familiarity of typical and distinctive faces to measure the effect on attractiveness. In our first experiment, we collected ratings of attractiveness, distinctiveness, and familiarity using three different groups of participants. Our stimuli included 84 images of female faces, presented in a full-face view. We replicated the finding that attractiveness ratings negatively correlate with distinctiveness ratings. In addition, we showed that attractiveness ratings were positively correlated with familiarity ratings. In our second experiment, we demonstrated that increasing exposure to faces increases their attractiveness, although there was no differential effect of exposure on typical and distinctive faces. Our results suggest that episodic familiarity affects attractiveness ratings independently of general or structural familiarity. The implications of our findings for the 'face-space' model are discussed.     

Coordination of grip configurations as a function of force output

In this investigation, the authors examined the coordination and control of force production by the digits of the hand as a function of criterion force level and grip configuration. Each adult participant (N = 6: 3 men and 3 women) was required to place the thumb and a finger (or fingers) upon load cells that were fixed to a grasping apparatus that was clamped to a table. In the task, participants had to match a criterion continuous constant total force level displayed on a computer screen. There were 10 trials at each grip configuration and criterion force level combination on each of 3 consecutive days. The results showed that (a) different grip configurations minimized error at each force level; (b) there was a specific digit pairing within a given grip configuration that produced the highest correlation of force output; (c) the correlation between the force output of digits generally increased at higher force levels; (d) error was reduced at each force level and grip configuration over the practice period; and (e) the organization of the force output of each digit varied as a function of digit, force level, grip configuration, and practice. The findings are consistent with the hypothesis that coordination of the digits in prehension is reflective of an adaptive, task-specific solution that is modified with practice.     

On learning to move randomly

In 2 experiments, the authors examined whether and to what degree young adults can learn to produce random planar motion of the index finger or fingers. Three different types of information feedback were provided to the participants (N = 8 in each experiment) over up to 5 days of practice across the 2 experiments. The results from both experiments revealed that the participants produced a relatively low level of movement randomness in finger motion and that they did not learn through practice to enhance the stochastic properties of their movement under any feedback conditions. The findings provide further evidence that there are relatively tight constraints on the number of dimensions that are regulating single-limb planar motion and that those constraints are not susceptible to change through typical learning protocols.     

Beyond curve fitting: a dynamical systems account of exponential learning in a discrete timing task

The authors examined the function for learning a discrete timing task from a dynamical systems perspective rather than solely the traditional curve-fitting viewpoint. Adult participants (N = 8) practiced a single-limb angular movement task of 125 ms over 20 degrees for 200 trials. There was no significant difference in percentage of variance accounted for in 3 parameter exponential and power-law nonlinear fits to the individual and averaged data. The percentage of variance increased in both exponential and power-law equations when the data were averaged over participants and trials. Drawing on a dynamical systems approach to time scales in motor learning and on analysis of the distinctive features of exponential and power-law functions, however, the authors conclude that the exponential is the learning function for that task and that level of practice.     

The importance of corporate and salesperson expertise and trust in building loyal business-to-business relationships in China

International relationships are critical to business success in this increasingly interdependent world. China is the world’s second largest economy and may soon overtake the United States in the near future. Thus, it becomes important for potential trading partners to understand how to effectively develop and maintain business relationships with this growing economic entity. In this study, we surveyed Chinese business people with purchasing responsibilities to better understand the dynamics of their business-to-business relationships. The data were empirically analyzed using structural equation modeling to test the interrelationship between perceptions of salesperson and corporate expertise, trust and loyalty. The results suggest that trust and expertise play key roles in developing long-term business-to-business associations in China. Managerial implications are discussed and avenues of future research are proposed.     

Speed influences on the scaling behavior of gait cycle fluctuations during treadmill running

The current study examined the temporal structure of gait cycle fluctuations in running. Participants ran at 80%, 90%, 100%, 110% and 120% of preferred running speed for 8min trials. Kinematic and kinetic gait cycle variables were generated from ground reaction force data. Mean, SD and CV of the kinematic and kinetic variables changed linearly with speed, whereas U-shaped functions were found for the scaling exponent alpha in 5 of the 8 variables investigated. Our findings reveal that long range correlations are present in both kinetic and kinematic variables of the gait cycle. The dependent structure of the stride interval is reduced at preferred running speed and this is hypothesized to be related to the enhanced stability and flexibility of this gait speed.     

On No-KR tests in motor learning, retention and transfer

In this paper we examine the role of no-knowledge of results (KR) tests in motor learning, retention and transfer. A distinction is drawn between studies of KR and studies of other issues in motor learning that use a No-KR test. Arguments are presented against the currently received position that a No-KR test is an essential protocol to examine motor learning, although a No-KR test is most relevant in the few contexts where the outcome information is not naturally available. Perspectives are provided on the limited though proper role of No-KR tests in motor learning, retention and transfer and these are illustrated through experimental examples. It is proposed that the current restrictive interpretation of KR as only augmented outcome information is narrowing not only the context of KR research but also the study of motor learning in general.
