Psychological evidence in the courtroom: critical reflections on the general acceptance standard

The increasing ties between psychology and law have familiarized psychologists with the standards by which law admits scientific evidence into the courtroom. In the USA, these include the general acceptance standard and the Daubert guidelines and, in the UK, the Turner Rule. However, the psychological literature has largely failed to make clear the degree of legal debate that exists concerning the clarity and effectiveness of such standards. This paper will focus on the general acceptance standard, examining key problems of this standard and placing them in a specifically psychological context. Such consideration is important precisely because the standard has become so well known within the psychological literature and because insufficient attention has been given to the way in which it operates implicitly within jurisdictions outside the USA. The authors argue that it is the responsibility of psychologists to become more involved in the debate concerning admissibility standards, given the credibility and authority that law accords to psychology when admitting it into the courtroom. In particular, psychologists need to become more self-reflective about their role in creating and maintaining such standards. © 1998 John Wiley & Sons, Ltd.     

科学划界视域下心理学学科焦虑与学科自觉

心理学科学划界是心理学发展史上的根本问题,构成了心理学发展历史研究的出发点和逻辑起点。心理学科学划界观点多样,争论不休,导致心理学处于学科焦虑当中。当前,心理学需要以文化文思促进学科自觉,这其中隐含的不仅仅是对心理学科学化追求道路的深入思考,同时,也是实现心理学话语方式转换以及与科学关系的深刻把握。     

The Effects of Extrinsic Motivation on Scientific and Artistic Creativity among Middle School Students

The present study tested the effects of extrinsic motivation on scientific and artistic creativity among Chinese middle school students. In Study 1, a between-groups design was applied to examine the effects of expected rewards on scientific and artistic creativity among 123 students, and in Study 2 the same design was applied to examine the effects of expected evaluation from different raters on scientific and artistic creativity among 120 students. We also considered the effects of grade and gender in both studies. The results of Study 1 indicated that expected material reward had significant negative effects on scientific creativity for 7th graders, while expected social reward had significant positive effects on scientific creativity for 8th graders, and both expected material and social rewards had significant positive effects on artistic creativity. The results of Study 2 indicated that expected evaluation from teachers and classmates had significant negative effects on scientific creativity and significant positive effects on artistic creativity. These results suggest that there is no one-size-fits-all answer to the effects of extrinsic motivation and creativity, Factors such as culture, type of extrinsic motivation, grade, and domains of creativity must be fully considered when cultivating adolescents’ creativity.     

Molecular (moment-to-moment) and molar (aggregate) analyses of behavior

Ten meanings or usages of the terms molecular and molar analyses are based on (1) numbers of responses, (2) durations of activities, (3) levels, (4) scales, (5) contiguity versus correlation, (6) behavioral standards, (7) function with or without structure, (8) local versus global phenomena, and (9) control by shaping of sequential moment-to-moment behavior. These usages reveal divisive viewpoints along with ambiguities in the Law of Effect, the definition of an operant, response strength, response probability, random behavior, time allocation, shaping, controlled versus uncontrolled operants, and roles for ordinary language. Usage 10 is less divisive and combines, and in that sense unifies, molecular behavior, defined as shaped moment-to-moment sequential behaving, and molar, defined as averages of aggregates of those shaped responses. It combines shaping, that establishes and changes operant behaviors, and strengthening that changes the amounts of those shaped behaviors. I conclude that general behavioral theory will combine strengthening with such methods as parametric, hybrid, or nonparametric shaping, and will use computational methods to simulate moment-to-moment behavior streams from which any aggregates of theoretical interest may be computed. Such a synthesis may not require different levels, scales, or new scientific paradigms.     

A comparison of sources of baseline data for treatments of problem behavior following a functional analysis

It is common practice in research on the treatment of problem behavior to compare levels of targeted behaviors during treatment to levels when treatment is not in place. Some researchers use data collected as part of a multielement functional analysis as the initial baseline, whereas others collect new baseline data following completion of the functional analysis. We evaluated whether the source of baseline data influences the reliability and efficiency of decision-making. Results suggest that similar decisions are made in regard to treatment efficacy using the different sources of baseline data, but using data from a multielement functional analysis as baseline may save time. Interrater agreement was adequate, but lower for some graphs than has been observed in past studies. Several potential explanations for this discrepancy are discussed.     

Science and the Future of Theology: Critical Issues

The ambivalent reputation of theology as an academic discipline is attributed to the often circular character of its procedures based on presumed authoritative sources. Recently, science too has come under the shadow of "postmodernist" critiques but, it is argued, has been able to withstand them successfully and make epistemologically warrantedclaims to be depicting reality—thereby vindicating human rationality. Evolutionary epistemological considerations also reinforce confidence in the more general deliverances of the human exploration of reasonableness through inference to the best explanation (IBE). The consequences of applying IBE, with its associated criteria, in theological investigation are considered in relation to theology as it is and as it might be. A number of issues critical for thedevelopment of a credible theology are identified. In spite of the challenging and somewhat negative view of contemporary theology to which this leads, hope is expressed that a genuinely credible "evangelical,""catholic," and liberal theology may yet emerge for the new millennium.

Theology: Reduction or Autonomy?

Issues of the nature and task of theology remain important to the science-theology dialogue. This paper lays out a framework for understanding the nature of theology in relation to the other sciences. In particular, I argue that the primary question remains one of autonomy and reduction. If theology is a genuine academic discipline, then it should be an autonomous field with its own subject matter and norms. Wolfhart Pannenberg argues that theology is the science of God, but I suggest that theology be more broadly understood as the science of meaning. If we recognize this, the modes of interaction between theology and the other sciences becomes clearer.
