Houses built on sand: effects of exemplar stability on susceptibility to attitude change

Attitude representation theory (C. G. Lord & M. R. Lepper, 1999) explains both attitude-behavior consistency and attitude change with the same principles. When individuals respond evaluatively to an attitude object, they activate and combine assumptions about the attitude object with perceptions of the immediate situation. The assumptions activated can vary across time, even without additional information. Previous research has shown that individuals activate exemplars when answering attitude questions, attitude reports vary with the valence of the assumptions activated, and activating differently liked exemplars reduces attitude-behavior consistency. The present research completed study of the theoretical implications of exemplar stability by showing that individuals with temporally unstable exemplars, whether spontaneous (Experiment 1) or manipulated (Experiments 2 and 3), are more susceptible to subsequent attitude change than are individuals with stable exemplars.     

LEO-II and Satallax on the Sledgehammer test bench

Sledgehammer is a tool that harnesses external first-order automatic theorem provers (ATPs) to discharge interactive proof obligations arising in Isabelle/HOL. We extended it with LEO-II and Satallax, the two most prominent higher-order ATPs, improving its performance on higher-order problems. To explore their usefulness, these ATPs are measured against first-order ATPs and built-in Isabelle tactics on a variety of benchmarks from Isabelle and the TPTP library. Sledgehammer provides an ideal test bench for individual features of LEO-II and Satallax, revealing areas for improvements.     

A Quality Life in the Shadow of Terrorism

After the demise of the Soviet Union, many individuals felt a sigh of relief as fear was leaving them. Yet, over the years, counselors have seen a new fear—terrorism—demonstrated in drive-by shootings, hate crimes, and now, weapons of mass destruction. In helping clients deal with this all-too-real phenomenon, a reframing process is in order, one that views our lives not in permanence, but as constant change. Much needless suffering is due to clinging to permanent belief systems, which, in reality, are impermanent. Many clients I have worked with have found effective ways not only to deal with, but to flourish in whatever life brings, via a self-Being relationship.     

Parents of the Battered Child: A Multidisciplinary Group Therapy Approach to Life-Threatening Behavior

ABSTRACT: This paper reports the demographic findings and the experience of a three-year, multidisciplinary group psychotherapy program, with 31 child-abusing families. No predictive demographic characteristics were identified. The abuse of children ranged from mild bruising to severe brain damage and multiple fractures. Group therapy as an intervention procedure had its successes and failures. The dynamics of male-female co-therapists, the peer group sharing, and the capacity to ultimately verbalize inadequacies in the parenting role were crucial factors in therapy. As an experiential encounter the study gives a poignant insight into the personal and family pathology of parents who abuse their children.     

Anxiety sensitivity: a unique predictor of dropout among inner-city heroin and crack/cocaine users in residential substance use treatment

The present study examined the extent to which anxiety sensitivity (AS) at treatment entry was related to prospective treatment dropout among 182 crack/cocaine and/or heroin-dependent patients in a substance use residential treatment facility in Northeast Washington, DC. Results indicated that AS incrementally and prospectively predicted treatment dropout after controlling for the variance accounted for by demographics and other drug use variables, legal obligation to treatment (i.e., court-ordered vs. self-referred), alcohol use frequency, and depressive symptoms. Findings are discussed in relation to the role of AS in treatment dropout and substance use problems more generally.     

The client as expert: Researching hindering experiences in counselling

This paper identifies the importance of valuing clients’ experiences when seeking to understand hindering experiences in counselling. Since the research literature reports that client perceptions of counselling are better predictors of outcome than counsellor ratings, client viewpoints are critical to furthering understanding of hindering experiences. Clients are generally reluctant to share negative experiences and a discussion regarding the difficulty in soliciting these experiences is presented. Examples of the process of conducting a client-oriented investigation into hindering experiences convey some of these difficulties. Several implications for counselling practice are addressed: (1) the need for counsellors to notice and repair hindering experiences, (2) the value of attending to the quality of the relationship, (3) the need for counsellors to cultivate flexibility and responsiveness, and (4) the use of methods to encourage clients to share their unspoken experiences.     

An extension of the Riggs projection colorimeter

A method for the construction and calculation of CIE chromaticity coordinates from a simple and inexpensive projection colorimeter is presented. The device allows variation along the dimensions of hue, saturation, and brightness and specification of these variations in terms of chromaticity coordinates, dominant wavelength, relative luminance, and excitation purity.
