Jump start exit criterion: Exploring a new model of service delivery for the treatment of childhood feeding problems

While the literature on the assessment and treatment of childhood feeding disorders continues to grow, little research has focused on developing new forms of service delivery. This study demonstrates the effectiveness of a brief, intensive intervention for the treatment of food selectivity in three boys who had failed to progress in traditional outpatient treatment. The implications of this model of service delivery are discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

Visual and verbal working memory loads interfere with scene-viewing

Working memory is thought to be divided into distinct visual and verbal subsystems. Studies of visual working memory frequently use verbal working memory tasks as control conditions and/or use articulatory suppression to ensure that visual load is not transferred to verbal working memory. Using these verbal tasks relies on the assumption that the verbal working memory load will not interfere with the same processes as visual working memory. In the present study, participants maintained a visual or verbal working memory load as they simultaneously viewed scenes while their eye movements were recorded. Because eye movements and visual working memory are closely linked, we anticipated the visual load would interfere with scene-viewing (and vice versa), while the verbal load would not. Surprisingly, both visual and verbal memory loads interfered with scene-viewing behavior, while eye movements during scene-viewing did not significantly interfere with performance on either memory task. These results suggest that a verbal working memory load can interfere with eye movements in a visual task.

     

INCREASING TREATMENT ACCEPTABILITY THROUGH VIDEO

The effects of a video vignette on the treatment acceptability ratings of four behavioral interventions were evaluated. Two interventions involved positive reinforcement (DRO and DRI) and two negative consequences (contingent physical restraint and contingent electric shock). Seventy-four undergraduate psychology students were randomly assigned into two groups. The experimental group (n=36) viewed a video vignette of a self-abusive individual whereas the control group (n=38) did not. Acceptability ratings prior to the video showed no differences between the experimental and control groups. The post video ratings indicated significant acceptability increases for physical restraint for the experimental group. There also was a significant group by testing effect because the means for the experimental group rose whereas the control group's means were stable. These results replicated and extended Foxx, McHenry and Bremer (in press) who showed that treatment acceptability is alterable through video.     

Beyond the family system

This paper comes from a workshop we ran at the 1980 A.F.T. Annual Conference at Bangor. It looks at the wider context of family therapy and the systemic view and attempts to open up areas for further investigation.     

COULD GOD CREATE DARWINIAN ACCIDENTS?

Abstract Charles Darwin, in his discussions with Asa Gray and in his published works, doubted whether God could so arrange it that exactly the desired contingent events would occur to cause particular outcomes by natural selection. In this paper, I argue that even a limited or neo‐Leibnizian deity could have chosen a world that satisfied some arbitrary set of goals or functions in its outcomes and thus answer Darwin's conundrum. In more general terms, this supports the consistency of natural selection with providentialism, and makes “theistic evolutionism” a coherent position to hold.     

Why does lag affect the durability of memory-based automaticity: Loss of memory strength or interference?

In Rickard, Lau, and Pashler's (2008) investigation of the lag effect on memory-based automaticity, response times were faster and proportion of trials retrieved was higher at the end of practice for short lag items than for long lag items. However, during testing after a delay, response times were slower and proportion of trials retrieved was lower for short lag items than for long lag items. The current study investigated the extent to which the lag effect on the durability of memory-based automaticity is due to interference or to the loss of memory strength with time. Participants repeatedly practiced alphabet subtraction items in short lag and long lag conditions. After practice, half of the participants were immediately tested and the other half were tested after a 7-day delay. Results indicate that the lag effect on the durability of memory-based automaticity is primarily due to interference. We discuss potential modification of current memory-based processing theories to account for these effects.     

Residual Effects of Slavery: A Delphi Study

Slavery and its aftermath have created multiple challenges that are unique to the African American community. Although literature exists within other disciplines, no published empirical study within the marriage and family therapy literature has examined the residual effects of slavery. We used a modified Delphi methodology to explore the residual effects of slavery on African Americans and to determine resultant clinical implications. To obtain information from panelists who have expertise in this area, we conducted three rounds of data collection: an open-ended questionnaire, a Likert-scale questionnaire, and a round of in-depth interviews. Based on our analysis of the data collected, this empirical study describes the influence of the residual effects of slavery, implications for clinicians and directions for future research.
