Biofeedback without a technical team--simple and cost effective

An important psychotherapeutic process is that of autogenous training, whose effectiveness can be improved by the use of biofeedback. Biofeedback procedures have hitherto called for considerable expenditure on apparatus and frequent therapy sessions. Despite this, it has not been possible to extend the relaxation effect to more general situations. This paper describes an inexpensive and practical method of utilising all the advantages afforded by the underlying therapeutic concept, on the basis of experience gained with cutaneous thermography. Further information, notably on the preparation of the laminae, can be had on request from the authors.     

Eating disorder NOS (EDNOS): an example of the troublesome "not otherwise specified" (NOS) category in DSM-IV

The “Not Otherwise Specified” (NOS) category within DSM-IV is designed for disorders of clinical severity that are not specified within broad diagnostic classes. “NOS” diagnoses are intended to be residual categories and they tend to be neglected by researchers. This can be inappropriate. The problems associated with certain NOS diagnoses are well illustrated by “Eating Disorder NOS” (sometimes termed EDNOS), which is the most common category of eating disorder encountered in routine clinical practice yet it has barely been studied. Indeed, there has been no research on its treatment. Interim and longer-term conceptual and practical solutions to the anomalous status of eating disorder NOS are proposed including the creation of a new diagnosis termed “mixed eating disorder”. Several of these solutions are of relevance to NOS categories in general. All the solutions should fulfil criteria for clinical utility.     

Orbital prefrontal cortex and guidance of instrumental behavior of rats by visuospatial stimuli predicting reward magnitude

The orbital prefrontal cortex (OPFC) is part of a circuitry mediating the perception of reward and the initiation of adaptive behavioral responses. We investigated whether the OPFC is involved in guidance of the speed of instrumental behavior by visuospatial stimuli predictive of different reward magnitudes. Unoperated rats, sham-lesioned rats, and rats with bilateral lesions of the OPFC by N-methyl-D-aspartate (NMDA) were trained in a visuospatial discrimination task. The task required a lever press on the illuminated lever of two available to obtain a food reward. Different reward magnitudes were permanently assigned to lever presses to respective sides of the operant chamber; that is, responses to one lever (e.g., the left one) were always rewarded with one pellet and responses to the other lever with five pellets. On each trial, the position of the illuminated lever was pseudorandomly determined in advance. Results revealed that OPFC lesions did not impair acquisition of the task, as the speed of conditioned responses was significantly shorter with expectancy of a high reward magnitude. In addition, during reversal, shift and reshift of lever position–reward magnitude contingencies and under extinction conditions, performance of the OPFC-lesioned and control groups did not differ. It is concluded that the OPFC in rats might not be critical for adapting behavioral responses to changes of stimulus–reward magnitude contingencies signaled by visuospatial cues.     

Characteristics of personally important episodic memories,counterfactual thoughts,and future projections across age and culture

We have limited knowledge as to whether the phenomenological differences between episodic memories, counterfactuals, and future projections show the same pattern across age groups and diverse samples. Here we compared the characteristics of these mental events, reported by younger and older participants in a Turkish (Study 1) and in an American sample (Study 2). In both studies, memories contained more sensory-perceptual-spatial details, were easier to bring to mind, and more specific. Future projections were the most positive, whereas counterfactuals were the least emotionally intense. In Study 1, older participants rated the events more positively and experienced them with more perceptual detail, whereas younger participants reported the future to be more voluntarily rehearsed, important, and central. These age differences did not replicate in Study 2. Overall, phenomenological differences between the events are robust and replicate across diverse samples. However, age differences are more sensitive to cultural or individual differences.     

In-Home Family Services: Providing Lasting Results to Crisis Helpline Callers

Families oftentimes struggle with issues that seem too burdensome to bear alone. In an effort to alleviate this burden, Boys Town partnered with the Nebraska Region VI Office of Mental Health to provide in-home services to families calling the Nebraska Family Helpline. Results indicate that families experienced a significant reduction in stress and were able to remain intact. Follow-up data indicate that outcomes were maintained up to twelve months after case closure. This preliminary evidence suggests that this type of early intervention can have an impact on families not involved in public systems, but who are voluntarily asking for help.

The Logic of the Trinity

Roughly, the problem of the Trinity is the problem of how God can be one and yet be the Father, the Son, and the Holy Spirit, which are three, not one. That one thing is identical with three distinct things seems to violate traditional laws of identity. I propose a solution to this problem according to which it is just an ordinary claim of one-many identity. For example, one pair of shoes is identical with two shoes; and my one body is identical with its six limbs of arms, legs, head, and torso. The pair of shoes is not identical with each one of the two shoes, nor is my body identical with each one of its six limbs, but rather identical with all of them taken together, or collectively. I argue that the problem of the Trinity should be understood accordingly: God is identical with the Father, the Son, and the Holy Spirit collectively, but not with each one of them distributively. According to the way I develop this proposal, no traditional laws of identity are violated, but merely generalized in an intuitive way. I argue that this is compatible with Christian Orthodoxy as given by the Athanasian Creed. I end by responding to some anticipated objections.     

Bayesian analysis of longitudinal multitrait–multimethod data with ordinal response variables

A new multilevel latent state graded response model for longitudinal multitrait–multimethod (MTMM) measurement designs combining structurally different and interchangeable methods is proposed. The model allows researchers to examine construct validity over time and to study the change and stability of constructs and method effects based on ordinal response variables. We show how Bayesian estimation techniques can address a number of important issues that typically arise in longitudinal multilevel MTMM studies and facilitates the estimation of the model presented. Estimation accuracy and the impact of between‐ and within‐level sample sizes as well as different prior specifications on parameter recovery were investigated in a Monte Carlo simulation study. Findings indicate that the parameters of the model presented can be accurately estimated with Bayesian estimation methods in the case of low convergent validity with as few as 250 clusters and more than two observations within each cluster. The model was applied to well‐being data from a longitudinal MTMM study, assessing the change and stability of life satisfaction and subjective happiness in young adults after high‐school graduation. Guidelines for empirical applications are provided and advantages and limitations of a Bayesian approach to estimating longitudinal multilevel MTMM models are discussed.
