Aging, working memory, and discrimination learning

Older adults easily learn probabilistic relationships between cues and outcomes when the predictive event is the occurrence of a cue, but have greater difficulty when the predictive event is the nonoccurrence of a cue (Mutter & Pliske, 1996; Mutter & Plumlee, 2004; Mutter & Williams, 2004). This study explored whether this age-related deficit occurs in a simpler learning context and whether it might be related to working memory (WM) decline. We gave younger and older adults simultaneous discrimination tasks that allowed us to compare their ability to learn deterministic relationships when either the occurrence (feature positive; FP) or the nonoccurrence (feature negative; FN) of a distinctive feature predicted reinforcement. We also included a group of younger adults who performed the discrimination tasks under a concurrent WM load. Both age and WM load had a detrimental effect on initial FP and FN discrimination; however, these effects persisted only in FN discrimination after additional learning experience. Learning predictive relationships requires inductive reasoning processes that apparently do not operate as efficiently in individuals with reduced WM capacity. The impact of WM decline may ultimately be greater for negative cue-outcome relationships because learning these relationships requires more difficult inductive reasoning processes, which place greater demands on WM.     

Tillich on Salvation

Abstract : Paul Tillich holds that it is the responsibility of every generation to free the received tradition from assumptions that limit the vitality of Christian concepts. Salvation is often held hostage to an exclusive view that limits it to the people who have had contact with Jesus Christ. Tillich holds that Jesus as the Christ as the New Being overcame existential estrangement, making salvation a dynamic power that contends with the anxiety that is the inevitable accompaniment of finitude. This has universal implications.     

Health Related Quality of Life After Gastric Bypass Surgery

The majority of studies which have evaluated health related quality of life are limited in the duration of follow up. The objective of this study was to prospectively conduct an evaluation using a repeated cross sectional analysis of separate patient cohorts who were up to four years after gastric bypass surgery. Adult Roux-en-Y gastric bypass patients were recruited to the study. All patients were requested to complete a general health status questionnaire, the Short Form-36 (SF-36), before surgery or at their post operative out patient follow up visits. Patient weight was documented at each follow up visit. A cross sectional analysis was performed to evaluate SF-36 scores in each annual cohort. Data are reported as mean +/− S.D. Three-hundred-eight patients completed at least one SF-36 assessment [Initial assessment at the time of surgery, time 1, n = 245, 1y n = 149, 2y n = 70, 3y n = 59, 4y n = 61]. The SF-36 scores were greater (p < 0.05) in each of the separate post surgery cohorts for physical functioning, role limitations due to physical health, social functioning, pain, vitality, general health and the physical component summary (PCS) scores. While not comparing changes in scores within individuals over time, these data suggest early improvement especially in the physical dimension of health related quality of life. In this analysis, this finding was also observed in each of the separate cohorts up to 4 years after gastric bypass surgery.     

Scales,diagnoses, and child psychopathology: II. Comparing the CBCL and the DISC against external validators

Using a multimethod multistage screening procedure, the authors interviewed 201 parents and their children with the Diagnostic Interview Schedule for Children (DISC 2.1). In addition, parents completed the Child Behavior Checklist (CBCL) and other survey measures, while their children completed self-report scales. Receiver operating characteristic (ROC) analyses were done to determine optimal cutpoints on the CBCL, referenced to DISC diagnostic caseness. DISC diagnoses, DISC stem symptoms, CBCL scores, and CBCL ROC-cutpoints were compared against external validators, in order to determine the comparative advantages of each approach for assessing child psychopathology. Overall findings suggest that the controversies about best assessment strategies may be artificial: When both assessment approaches are compared using similar methods, they are reasonably comparable. However, highly specific diagnostic categories may show fewer relationships with external validators and may therefore need more systematic validational studies.The opinions and assertions contained in this paper are the private views of the authors and are not to be construed as official or as reflecting the views of the Department of Health and Human Services, the National Institute of Mental Health, the Walter Reed Army Institute of Research, or the Department of the Army.     

The Consulting Process: A Multidimensional Approach

The consulting process seems to work similarly regardless of whether the consultant is internal or external or is doing individual or group consultation. Some differences may occur depending on whether the consultant is a process helper or content helper, although good content-focused consultants often possess excellent process skills and use them as a regular part of the consulting process. Several consultation processes were reviewed, and from this a six-step approach is presented.     

A comparison of parent-education methods in maternity wards

This study investigated the effect of three parent-education methods for use with mothers in maternity wards. The three methods were videotapes and a handbook, videotapes only, and handbook only. The two groups who received the videotapes performed better on a posttest than two no-treatment control groups. No differences were evident between the videotapes and handbook group and the videotapes-only group. The handbook-only condition was better than only one of the control groups. Usefulness of the program, problems encountered, and future research needs are discussed.     

Entrepreneurship research and practice: a call to action for psychology

Entrepreneurship is a major source of employment, economic growth, and innovation, promoting product and service quality, competition, and economic flexibility. It is also a mechanism by which many people enter the society's economic and social mainstream, aiding culture formation, population integration, and social mobility. This article aims to illuminate research opportunities for psychologists by exposing gaps in the entrepreneurship literature and describing how these gaps can be filled. A "call to action" is issued to psychologists to develop theory and undertake empirical research focusing on five key topic areas: the personality characteristics of entrepreneurs, the psychopathology of entrepreneurs, entrepreneurial cognition, entrepreneurship education, and international entrepreneurship. Methodological issues are discussed and recommendations provided. It is shown that psychologists can help identify the factors that influence new venture creation and success and inform the construction of public policy to facilitate entrepreneurship.
