Conceptual and perceptual memory: retrieval orientations reflected in event-related potentials

In memory retrieval, search can be guided by mental sets towards different subsets of the available evidence. Such retrieval orientations have been suggested to leave an imprint on event-related potentials (ERPs). The present study aimed at characterizing orientations towards perceptual and conceptual evidence in a recognition task, where pictures and words were studied. In the recognition test, items were presented in either the same format as at study or in the opposite format. A between-subjects manipulation modified the task, instructing an Exclusion group to endorse only items that preserved their format from study, and an Inclusion group to endorse both formats of a studied item. It was hypothesized that exclusion instructions would instill a perceptual and inclusion instructions a conceptual orientation. As a corollary, instructions were expected to dissociate the high end from the low end of the picture-word mirror effect. This expectation was confirmed in a behavioural experiment. In an ERP experiment, retrieval orientations were examined in their effects on correct rejections of new pictures and words. Confirming earlier findings [Hornberger, M., Morcom, A. M., & Rugg, M. D. (2004). Neural correlates of retrieval orientation: effects of study-test similarity. Journal of Cognitive Neuroscience, 16(7), 1196-1210], a perceptual orientation was accompanied by more positive-going amplitudes over widespread areas. The difference was larger for pictures than for words, supporting behavioural evidence that new pictures are more easily rejected on perceptual grounds than are new words. The Exclusion group showed no ERP evidence of cross-format old-new effects, despite reaction times indicative of involuntary conceptual recognition. The results indicate that perceptual and conceptual retrieval orientations imprint distinct signatures on ERPs. They further suggest that the examined old-new effects in ERPs are mainly linked to voluntary aspects of memory, even in a task where involuntary memory exerts effects on reaction times.     

The moral judgment test: comments on Villegas de Posada's critique

The Moral Judgment Test is an operationalization of Kohlberg's notion of moral judgment competence and Piaget's two-aspect model of behavior and thus differs from tests of preferred moral orientations and Kohlberg's own Stage measurement. As this best presents counter-arguments to be rated in regard to their moral quality, it is a difficult task for many, and the C score reflects the respondents' competence to cope with the task. Validation studies of 27 language versions and thirty years of use in research and evaluation studies have indicated the Moral Judgment Test is valid and useful for assessing affective and cognitive aspects of moral behavior for research and evaluation.     

Selective pressures on the once and future contents of ethnic stereotypes: effects of the communicability of traits

It is hypothesized that traits that are most likely to be the subject of social discourse (i.e., most communicable) are most likely to persist in ethnic stereotypes over time and that this effect is moderated by the extent to which an ethnic group is the subject of social discourse. Study 1 yielded communicability ratings of 76 traits. Study 2 tested the relation between a trait's communicability and its presence in stereotypes of 4 Canadian ethnic groups. Study 3 tested the relation between a trait's communicability and its persistence over time in stereotypes of 8 American ethnic groups. Results supported the hypotheses. A communication-based analysis of stereotypes appears helpful in predicting persistence and change in the contents of stereotypes of real groups in the real world.     

Virtual reality for the psychophysiological assessment of phobic fear: responses during virtual tunnel driving

An overall assessment of phobic fear requires not only a verbal self-report of fear but also an assessment of behavioral and physiological responses. Virtual reality can be used to simulate realistic (phobic) situations and therefore should be useful for inducing emotions in a controlled, standardized way. Verbal and physiological fear reactions were examined in 15 highly tunnel-fearful and 15 matched control participants in 3 virtual driving scenarios: an open environment, a partially open tunnel (gallery), and a closed tunnel. Highly tunnel-fearful participants were characterized by elevated fear responses specifically during tunnel drives as reflected in verbal fear ratings, heart rate reactions, and startle responses. Heart rate and fear ratings differentiated highly tunnel-fearful from control participants with an accuracy of 88% and 93%, respectively. Results indicate that virtual environments are valuable tools for the assessment of fear reactions and should be used in future experimental research.     

Neurocognitive Effects of Methamphetamine: A Critical Review and Meta-analysis

This review provides a critical analysis of the central nervous system effects of acute and chronic methamphetamine (MA) use, which is linked to numerous adverse psychosocial, neuropsychiatric, and medical problems. A meta-analysis of the neuropsychological effects of MA abuse/dependence revealed broadly medium effect sizes, showing deficits in episodic memory, executive functions, information processing speed, motor skills, language, and visuoconstructional abilities. The neuropsychological deficits associated with MA abuse/dependence are interpreted with regard to their possible neural mechanisms, most notably MA-associated frontostriatal neurotoxicity. In addition, potential explanatory factors are considered, including demographics (e.g., gender), MA use characteristics (e.g., duration of abstinence), and the influence of common psychiatric (e.g., other substance-related disorders) and neuromedical (e.g., HIV infection) comorbidities. Finally, these findings are discussed with respect to their potential contribution to the clinical management of persons with MA abuse/dependence.     

Werden Psychotherapeuten,Psychiater oder die Psychotherapie stigmatisiert?

Background

In the last decades much has been found out about the stigmatization of persons with mental illnesses. Recently, a potential stigmatization of psychologists, psychiatrists and psychotherapy has been debated.

Aim

The question should be answered whether there is any scientific evidence for stigmatization of psychologists, psychiatrists and psychotherapy by using the conceptualization of stigma as brought forward by Link and Phelan (Ann Rev Sociol 2001; 27:363–385).

Material and methods

For the systematic literature search in 2013 a databank search was carried out in Web of Science using the search terms stigma or discrimination or stereotypes or prejudice AND psychiatrist or psychotherapist or psychotherapy or mental health professional. A total of 2013 publications were identified which were systematically arranged according to the title and abstract with respect to the relevance for the question whether psychotherapy or associated professional groups are stigmatized. Only four of the articles were considered to be relevant. After advice from experts six further relevant articles could be found which did not appear in the databank search.

Results

The review found evidence for both positive and negative stereotypes but not for other components of the stigmatization process.

Conclusion

At present there is no evidence for a stigma related to psychotherapy or to the professions of psychotherapists and psychiatrists.     

Untersuchungen zur Psychologie der Wiedererzählung und des Gerüchtes

Ohne Zusammenfassung Anmerkung des Herausgebers: Mit der vorliegenden Arbeit habilitierte sich der Verfasser im Winter 1926 in der philosophischen Fakult?t der Universit?t Gie?en, w?hrend ich auf Urlaub in Amerika war. Unmittelbar nach der Habilitation brach bei ihm ein erbliches Leiden aus, das bald darauf seine v?llige Erblindung zur Folge hatte und nach wenigen Jahren seinem Leben ein Ende bereitete. Als ich im Sommer 1927 nach Gie?en kam, konnte ich nichts über den Verbleib des Manuskriptes erfahren, auch der Verfasser, mit dem ich einige Briefe wechselte, wu?te nichts mehr darüber zu sagen. Da? ich schlie?lich in den Besitz des Manuskriptes gekommen bin, veranke ich dem jetzigen Vorstand des psychologischen Institutes der Universit?t Gie?en, Herrn KollegenSander, mit dem ich die Angelegenheit auf dem letzten internationalen Kongre? in Kopenhagen besprach. — Es war mir ein Bedürfnis, meinem allzu früh verstorbenen Assistenten und Freund eine letzte Ehrung dadurch zu erweisen, da? ich seine letzte Arbeit zur Ver?ffentlichung bringe. Problem, Methode und Ausarbeitung sind sein Werk. Inzwischen hatF. C. Bartlett (Remembering, Cambridge 1932) ?hnliche, noch früher angestellte Versuche ver?ffentlicht, die dem Verfasser natürlich unbekannt waren und daher in seiner Arbeit nicht erw?hnt sein k?nnen.
