Meeting the Needs of Evidence-based Practice in Family Therapy: Developing the Scientist-practitioner Model

Effective models of clinical training have been and continue to be a primary topic of discussion in the field of family therapy, particularly given the needs of evidence-based practice. This article outlines the major historical and contemporary struggles of one such model of clinical training and practice: the scientist-practitioner model. Throughout the article, the principles of the scientist-practitioner model and evidence-based practices are compared and contrasted. Suggestions for overcoming the contemporary challenges faced by the scientist-practitioner in a family therapy practice or in an educational environment are discussed.     

Virginia Satir: An Integrated, Humanistic Approach

This article traces professional and personal influences that helped Virginia Satir to shape her worldview. She was an integrative humanist who included body, mind, emotional, and spiritual processes to transform systems ranging from the molecular to the cosmic. Her theories and techniques offered a wellspring of hope and possibility to individuals as well as large assemblies. The presentation of a case with young, abused children demonstrates her use of self (through physical touch) by sensitively reframing the cycle of violence as an opportunity for safe, cooperative contact.     

Critique or Misrepresentation? A Reply to Timimi et al.

In rebuttal to Timimi et al., we show that their critique is not a form of reasonable scientific debate with informed, constructive criticism, but merely a misrepresentation of the existing scientific literature on ADHD apparently designed to convince the scientifically uninformed of its nonexistence and of the misuse of medications for its management. We show their argument to be based on faulty logic, selective citation, misreprensentation of individual studies, ignorance of the vast literature on ADHD, and innuendo that maligns the integrity of scientists studying the disorder. Our original International Consensus Statement on ADHD remains untarnished by this faux critique – indeed it was intended to refute just such unsupported and unsupportable criticism that often appears in the popular media.     

The nanoeconomics of concurrent choice behavior

We introduce to behavior analysis a way of analyzing choice behavior that exploits recent developments in nanoeconomics, financial economics, and econometrics. A response return, modeled on an economic return, is the log differenced count of responses allocated to each of two alternatives during a short time window, compared with that in the immediately preceding window. The response return is a new dependent variable which offers a novel and useful way of looking at operant behavior, especially at the molecular level of analysis. The response–return series is a near‐instantaneous measure of an organism's dynamic preferences for each of two alternatives. Analyzing such a series requires time‐analytic techniques, including Auto‐Regressive Conditional Heteroskedastic (ARCH) models. We illustrate these techniques by analyzing choices between combinations of arithmetic and exponential variable‐interval schedules with pigeon subjects. All response–return series were well‐fitted by one of three ARCH‐family models. The fitted models were differentially sensitive to transition versus steady‐state data samples. The particular insights that the ARCH analyses offer are improved understanding of the effects of the instantaneous effects of reinforcers and their absence, of how the distribution of reinforcers in time affects choice, and of the differences between choice in transition and at steady state.     

Parent-reported executive functioning in young children treated for cancer

It is well known that children treated for cancer are at risk for cognitive and functional impairments. Such research is largely based on studies of late effects in school-aged or older children. However, far less is known about executive function weaknesses in preschool-aged children treated for cancer. Thus, the aim of this study was to examine executive functioning in a clinically referred sample of young oncology patients, and its association with broader domains of functioning. Data from 61 young children with cancer, who were referred for clinical cognitive evaluations, were abstracted and included in this study. Patients were 5.00 years of age (SD = 0.72) at assessment, 54.1% male, and two-thirds (63.9%) had been treated for brain tumors. Most executive functions were significantly discrepant from the mean, with 47.5% of preschoolers having parent-reported working memory concerns within the clinically significant range. There were no differences in executive functioning based on diagnosis or treatment status. Parent-reported executive functioning was strongly correlated with global intelligence and adaptive functioning, with some indices also associated with nonverbal problem solving and pre-academic skills. Ultimately, results indicate the presence of emerging weaknesses in executive functioning in young children with cancer, and add to a growing body of literature highlighting the potential cognitive and behavioral risks associated with a cancer diagnosis in early childhood.     

Dissociable spatial memory systems revealed by typical and atypical human development

Rodent lesion studies have revealed the existence of two causally dissociable spatial memory systems, localized to the hippocampus and striatum that are preferentially sensitive to environmental boundaries and landmark objects, respectively. Here we test whether these two memory systems are causally dissociable in humans by examining boundary‐ and landmark‐based memory in typical and atypical development. Adults with Williams syndrome (WS)—a developmental disorder with known hippocampal abnormalities—and typical children and adults, performed a navigation task that involved learning locations relative to a boundary or a landmark object. We found that boundary‐based memory was severely impaired in WS compared to typically‐developing mental‐age matched (MA) children and chronological‐age matched (CA) adults, whereas landmark‐based memory was similar in all groups. Furthermore, landmark‐based memory matured earlier in typical development than boundary‐based memory, consistent with the idea that the WS cognitive phenotype arises from developmental arrest of late maturing cognitive systems. Together, these findings provide causal and developmental evidence for dissociable spatial memory systems in humans.     

Exchange Taboos From an Interpretive Perspective

The relational framing perspective on taboo exchanges addresses a number of issues that have also been the subjects of considerable interpretive research and theorizing. This commentary highlights interpretive work on gift giving, love, sacredness, purity, and boundaries as it pertains to exchange taboos. It suggests that there is a ritual and moral substrate that underlies exchange behaviors. It concludes that the interpretive perspective may deepen relational framing by revealing an ideal moral template that guides behavior and leads to polite ruses in order to reframe behaviors that violate these norms. It further suggests that there is much to be gained by integrating insights from consumer psychology with those of consumer sociology and consumer anthropology.     

Ideal is typical.

A well-established finding in research on concepts and categories is that some members are rated as better or more typical examples than others. It is generally thought that typicality reflects centrality, that is, that typical examples are those that are similar to many other members of the category. This interpretation of typicality is based on studies in which participants had little knowledge about the relevant categories. In the present study, experienced fishermen were asked to give goodness-of-example ratings to familiar freshwater fish. These fishermen were of two cultural groups with somewhat different goals and ideals. Typicality was well predicted by fishes' desirability and poorly predicted by their centrality. Further, the two cultural groups differed in their typicality ratings in ways that corresponded to their different goals and ideals. For knowledgeable reasoners typicality in natural taxonomic categories appears based on ideals rather than on centrality.     

Creating political websites: Balancing complexity &; usability

By integrating what is known about how people navigate the overwhelming tide of political information with research on usability, the experiments reported in this article aim to provide information about how to create political websites that are usable, engaging, and educational. This article reports on a series of four different experiments (n=478) comparing a simpler and more easily navigable website to a more complex and interactive website. The types of websites tested include: adwatches, issue grids, candidate biographies, and campaign finance sites. The results suggest that simpler, more navigable websites are preferred to more interactive websites with web tools. Results also suggest that more political information is not always preferable, as in most cases, participants rated sites with more political information lower. Brett A.
