P300 latency, but not amplitude or topography, distinguishes between true and false recognition

Two experiments are described in which the P300 component of the event-related potential was recorded during a modification of the Deese-Roediger-McDermott false-memory paradigm. P300 amplitudes and topographies were evaluated in both true recognition of previously presented (studied) words and in false recognition of associatively related, never presented (critical lure) words. P300 topography and amplitude did not appear to differ between true and false recognition. However, false recognition of critical lures produced substantially shorter P300 latencies than did the true recognition of studied words.     

Validation of a Tibetan translation of the Hopkins Symptom Checklist 25 and the Harvard Trauma Questionnaire

This study sought to translate and validate the Hopkins Symptom Checklist-25 (HSCL) and the Harvard Trauma Questionnaire (HTQ) in a Tibetan population. Translated questionnaires were administered to 57 Tibetan survivors of torture/human rights abuses living in the United States and receiving services in a torture treatment program. Participants were evaluated to determine if they met criteria for major depressive episode, generalized anxiety disorder, or posttraumatic stress disorder (PTSD). Coefficient alpha for the HSCL Anxiety subscale (.89), Depression subscale (.92), and the HTQ (.89) were high. Diagnostic accuracy using receiver operating characteristic curve analysis generated good classification accuracy for anxiety (.89), depression (.92), and PTSD (.83). However, although sensitivity and specificity for HSCL subscales were quite high, the HTQ generated low sensitivity (.33), partly because of a low rate of PTSD. Results support the reliability and validity of the HSCL but suggest further study of the HTQ with this population is required.     

My father,Herbert Rosenfeld

Abstract

This is the modified version of the powerpoint that Angela Rosenfeld, the elder daughter of Herbert Rosenfeld (1910–1986) – one of Melanie Klein's most important collaborators – presented in Nuremberg, his native town, on October 5, 2014, upon the invitation of the German Psychoanalytic Society (DPG). In it, Angela Rosenfeld reconstructs not only her father's main life events, but also her personal relationship to him and the family climate in which she grew up. The traumas brought about by Hitler's rise to power in 1933 are partly still reflected in the holes and/or open questions that the author herself became aware of while writing and presenting the paper – and which profoundly touched and moved her audience.     

How simulations fail

‘The problem with simulations is that they are doomed to succeed.’ So runs a common criticism of simulations—that they can be used to ‘prove’ anything and are thus of little or no scientific value. While this particular objection represents a minority view, especially among those who work with simulations in a scientific context, it raises a difficult question: what standards should we use to differentiate a simulation that fails from one that succeeds? In this paper we build on a structural analysis of simulation developed in previous work to provide an evaluative account of the variety of ways in which simulations do fail. We expand the structural analysis in terms of the relationship between a simulation and its real-world target emphasizing the important role of aspects intended to correspond and also those specifically intended not to correspond to reality. The result is an outline both of the ways in which simulations can fail and the scientific importance of those various forms of failure.     

Formal reasoning in late adulthood: The role of semantic content and metacognitive strategy

Two experiments explored the availability of deductive or formal reasoning in late adulthood. In Experiment 1, fifty young (M=19.0 years) and 50 elderly adults (M=81.0 years) were assessed using adaptations of Wason's selection task and rated task content for familiarity, affect, and agreement. In Experiment 2, 100 young (M=21.0 years) and 100 elderly adults (M=81.0 years) were similarly assessed, with half of the subjects in each age group receiving a metacognitive strategy to facilitate reasoning. Results from Experiment 1 indicated equivalent reasoning among the groups on problems employed in earlier developmental research. In contrast, problems constructed to entail affect resulted in poorer performance by older adults. In Experiment 2, both young and older adults who used the metacognitive strategy reasoned equally acrossall problems. In both experiments, familiarity and agreement did not play a role in deductive reasoning performance, but affect seemed to be an interfering factor. Results are discussed in terms of competence-procedure and stability-decrement models of adult cognitive development.     

Sexual harassment experiences and equal opportunity perceptions of Navy women

In 1989, the Navy began tracking the sexual harassment rates among its officer and enlisted personnel by administering the Navy Equal Opportunity Sexual Harassment (NEOSH) Survey on a biennial basis. While previous reports on the results of the NEOSH Survey have discussed the occurrence, frequency, and effects of sexual harassment in the Navy [A. L. Culbertson, P. Rosenfeld, and C. E. Newell (1993) Sexual Harassment in the Active-Duty Navy: Findings from the Navy-Wide Survey (TR-94-2), San Diego, CA: Navy Personnel Research and Development Center], this study examines whether victims of sexual harassment differ in their perceptions of equal opportunity (EO) climate from those who have not been harassed. Data from the 1991 NEOSH Survey were reanalyzed. Sixty-seven percent of the women officers were White, 25% African-American, and 18% Hispanic. Of the women enlisted, 52% were White, 31% African-American, and 18% Hispanic. The results indicated that women who were sexually harassed perceived that there was less EO in the Navy than women who had not been harassed. This was true for both officer and enlisted personnel. In addition, specific organizational consequences of sexual harassment were identified.The opinions expressed in this paper are those of the authors, are not official and do not necessarily represent the views of the Navy Department.     

Unbiased and unnoticed verbal conditioning: the double agent robot procedure

Subjects who were told they were “experimenters” attempted to reinforce fluent speech in a supposed subject with whom they spoke via intercom. The supposed subject was to say nouns, one at a time, on request by the “experimenter”, who reinforced fluent pronunciation with points. Actually, the “experimenter” was talking to a multi-track tape recording, one track of which contained fluently spoken nouns, the other track containing disfluently spoken nouns. If the “experimenter's” request for the next noun was in a specified form a word from the fluent track was played to him as reinforcement; requests in any other form produced the word from the disfluent track. Repeated conditioning of specific forms of requests was accomplished with two subject-“experimenters,” who were unable to describe changes in their own behavior, or the contingencies applied. This technique improved upon an earlier method that had yielded similar results, but was less thoroughly controlled against possible human bias.
