The appropriateness of the MMPI-2 K correction

The extent to which the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) K scale serves as a suppressor variable that influences the validity of clinical scale scores was examined using 274 male and 425 female outpatients from a community mental health center and 105 male and 247 female clients from a university psychological clinic. Hierarchical regression analyses were performed with MMPI-2 K scale scores and clinical scale scores as predictors and therapist ratings as criteria. In most cases, the K scale did not act as a suppressor Optimal K weights were different from the traditional K corrections. In most instances, there were no significant differences between correlations of therapist ratings with K-corrected and uncorrected clinical scale scores. The results do not support the K scale as a suppressor variable in these settings, although additional research is needed in settings where higher levels of defensiveness are common.     

Perception and action influences on discrete and reciprocal bimanual coordination

For nearly four decades bimanual coordination, “a prototype of complex motor skills” and apparent “window into the design of the brain,” has been intensively studied. Past research has focused on describing and modeling the constraints that allow the production of some coordination patterns while limiting effective performance of other bimanual coordination patterns. More recently researchers have identified a coalition of perception-action constraints that hinder the effective production of bimanual skills. The result has been that given specially designed contexts where one or more of these constraints are minimized, bimanual skills once thought difficult, if not impossible, to effectively produce without very extensive practice can be executed effectively with little or no practice. The challenge is to understand how these contextual constraints interact to allow or inhibit the production of complex bimanual coordination skills. In addition, the factors affecting the stability of bimanual coordination tasks needs to be re-conceptualized in terms of perception-related constraints arising from the environmental context in which performance is conducted and action constraints resident in the neuromotor system.     

Emotional valence and reference disturbance in schizophrenia

The authors examined the impact of emotional valence on reference disturbance in patients with schizophrenia and identified factors that moderate individual differences in this relationship. Thirty-nine patients with schizophrenia were given an interview that elicited speech samples in response to 10 neutral and 6 negatively valenced emotional questions. Speech samples were analyzed using the Communication Disturbances Index (N. M. Docherty, M. DeRosa, & N. C. Andreasen, 1996). Participants were also assessed with the Positive and Negative Symptom Scale (S. Kay, 1991) and a single-trial Stroop task (Stroop, 1935). Group analyses indicated that negative questions elicited more unclear references than neutral questions. Both the severity of disorganization symptoms and selective attention deficits predicted increased reference errors in response to emotional questions.     

The virtual body of Christ and embrace of the seriously ill

ABSTRACT

Since the time of the Apostle Paul, the body of Christ has always been a virtual body, made up of members who were not always physically present to one another but were nevertheless part of the same catholic community. Virtual presence in today’s society comes most often via digital technology, a reality that prompts many Christian leaders and theologians to warn of the dangers of disembodied existence. This paper challenges the claim that virtual presence via digital technology is necessarily an inferior form of presence. Using autoethnographic research of living with advanced-stage cancer, the author explores how virtual connection via technology can sometimes be a superior form of presence for those undone by illness and other traumas. The article concludes with a call to churches to draw on biblical, theological, and liturgical resources to help imagine how digital devices can be used to practice healing forms of attentiveness to those who need it most.
