Implicita och explicita attityder om politiker : sociala och traditionella mediers påverkan / Implicit and explicit attitudes towards politicians : the influence of social and traditional mediaVinterfrost, Jenny, Järveläinen, Aino January 2012 (has links)
Tidigare forskning har visat att implicita och explicita attityder formas och förändras oberoende av varandra, samt att allt fler politiker använder sig av sociala medier för att nå ut till sina väljare. Denna studie syftade till att undersöka hur deltagarnas implicita och explicita attityder, gentemot två fiktiva politiker, påverkas av traditionella och sociala medier. I studien användes en experimentell mellangruppsdesign där deltagarna slumpmässigt fördelades till olika betingelser. Dessa bestod av positiva och negativa nyhetsitems från dels traditionella dels sociala medier. I undersökningen, som genomfördes på internet, deltog 126 personer. För att mäta deltagarnas attitydförändringar användes dels ett Implicit Association Test (IAT), dels ett explicit frågeformulär. Traditionella media påverkade explicita attityder signifikant.

Exploration of explicit and implicit emotion in adult survivors of childhood sexual abuseMckay, Eimear January 2013 (has links)
Background: Childhood sexual abuse (CSA) has the potential to compromise the socioemotional development of the victim resulting in an increased vulnerability to difficulties regulating emotions and one’s sense of self. Emotion is thought to play a key part in a number of psychological disorders which CSA survivors are at increased risk of developing. A better understanding of the basic emotions experienced in this population and emotion regulation will inform current treatment. Aims: This research aimed to develop a better understanding of the emotions experienced by survivors of CSA and the relationship between “implicit” and explicit emotions and psychopathology. Method: Two empirical studies were conducted. Study 1 employed a cross-sectional consecutive case series design involving 109 survivors of CSA. Participants completed a set of measures relating to basic emotions, emotion regulation and symptoms. Exploratory factor analyses were conducted on the Basic Emotions scale (BES). Regression analyses were used to explore the relationship between emotions experienced, emotion regulation strategies and psychological symptoms. Study 2 examined basic emotions, “implicit disgust self-concept” and psychopathology in a population of CSA survivors (n=26) and a group of individuals currently receiving psychological therapy who reported that they had not experienced childhood trauma (n=25). Participants completed self-report measures pertaining to emotion, emotion regulation, symptoms and cognitive fusion. Participants also completed an implicit association test. Results: Exploratory factor analyses supported the structure of three versions of the BESWeekly, General, and Coping in a sample of survivors of childhood sexual abuse. In all three versions of the scale, disgust explained the largest proportion of variance. The basic emotions of sadness, fear and disgust as well as external dysfunctional coping strategies appear to predict PTSD symptomatology in this sample. The results of Study 2 also support the finding that self-reported disgust is prominent in the emotion profile of CSA survivors. Implicit disgust self-concept was not significantly correlated with other emotions or psychopathology. However, implicit disgust self-concept was found to be significantly associated with cognitive fusion. Discussion: Psychotherapeutic approaches for survivors of childhood sexual abuse should address the emotional experience of this population. In particular, these findings suggest that sadness and disgust should be targeted in therapy.

Neurociências aplicadas ao ensino-aprendizagem da tecnologia nuclear / Neuroscience applied to the teaching-learning of nuclear technologyBarabás, Roberta de Carvalho 16 October 2018 (has links)
Embora a tecnologia nuclear tenha aplicações benéficas para diversas áreas, como saúde, indústria, agricultura, produção de energia, entre outras, a sua aceitação ainda é restrita e há várias barreiras para o seu uso. A falta de conhecimento assertivo sobre essa tecnologia gera preconceito com relação à sua utilização. Preconceitos podem ser explícitos, que são conscientes, ou implícitos, inconscientes. No entanto, conscientes ou inconscientes, eles influenciam o comportamento e as atitudes. As experiências nas memórias explícita e implícita podem ser transferidas de uma para a outra. Assim, preconceitos ou associações inconscientes podem ser modificados pela memória explícita, ou seja, um novo conhecimento pode reduzi-los ou revertê-los. Para uma educação transformadora, o professor tem um papel central; entretanto, para que ele transmita o conhecimento de forma imparcial, é necessário que tenha uma visão livre de preconceitos. Esse trabalho visa desenvolver uma metodologia com apoio em neurociências por meio da qual as associações implícitas referentes às aplicações da tecnologia nuclear por parte dos professores de ciências sejam identificadas e possíveis preconceitos implícitos sejam modificados por meio de novos conhecimentos explícitos. Para identificar preconceitos implícitos são necessários testes específicos de memória implícita. O Teste de Associação Implícita (TAI) foi selecionado para esse trabalho. Seguindo as etapas fornecidas pelo software FreeIAT, o TAI foi customizado a fim de comparar as associações implícitas de participantes com relação às áreas nuclear e petróleo e sua consistência foi averiguada por um pré-teste aplicado a um grupo de especialistas (grupo controle) e de leigos, cujos resultados determinaram um bom valor de Alfa de Cronbach. Um programa multissensorial de 5 horas foi desenvolvido e realizado no Instituto de Pesquisas Energéticas e Nucleares (IPEN) para um grupo de professores de ciências. O TAI foi aplicado no início e ao término do programa e os resultados das associações implícitas foram comparados. Após seis meses, o TAI foi reaplicado ao mesmo grupo de professores para verificar se as associações implícitas se mantiveram estáveis. Esse programa multissensorial foi comparado com um programa de 12 semanas de ensino tradicional com aulas expositivas realizado no IPEN para alunos ingressantes na pós-graduação. O programa multissensorial foi efetivo para mudar e manter as associações implícitas dos professores referentes às aplicações benéficas da tecnologia nuclear, diferentemente do ensino tradicional com aulas expositivas. Esse trabalho demonstrou que é possível quebrar paradigmas e preconceitos. A abordagem multissensorial possibilitou um conhecimento enriquecido sobre as aplicações da tecnologia nuclear, ou seja, promoveu novas experiências na memória explícita que modificaram as associações prévias armazenadas na memória implícita. Assim, o programa multissensorial demonstrou ser uma ferramenta eficaz, capaz de produzir e manter mudanças nas associações implícitas, de baixo custo e pode ser aplicado em diversas áreas para mudar as associações implícitas e reverter preconceitos. Os resultados demonstraram que esse trabalho de doutorado teve êxito no que se propôs, contribuindo, assim, para a difusão do conhecimento das aplicações benéficas da tecnologia nuclear e, consequentemente, para a sua desmitificação. Essa metodologia completa poderá ser empregada em outras áreas para identificar, modificar e/ou reverter preconceitos ou estereótipos implícitos. / Although the applications of nuclear technology benefit several fields, such as health, industry, agriculture, energy production, among others, its public acceptance is still reduced and there are various barriers to its use. A lack of assertive knowledge about this technology generates prejudice against its use. Prejudices may be explicit at the conscious level or implicit operating outside awareness. Nevertheless, either conscious or unconscious, prejudices interfere with behavior and attitudes. The experiences in the explicit and implicit memories can be transferred from one to the other; thus unconscious prejudices or associations may be modified by the explicit memory, that is, new knowledge may reduce or even reverse them. The teachers play a critical role for transforming education; however, for sharing balanced knowledge they must have a perspective without prejudices. This work aims to develop a neuroscience-based methodology through which implicit associations of Brazilian science teachers towards nuclear technology may be assessed and possible implicit prejudices may be changed by new knowledge. In order to identify implicit prejudices, specific implicit memory tests are required. The Implicit Association Test (IAT) was chosen for this work. By following the steps provided by the software FreeIAT, the IAT was customized aiming to compare the implicit associations of respondents towards nuclear and oil. A pretest with nuclear specialists (control group) and lay people was administered to check the consistency of the customized IAT. The Cronbach\'s alpha was applied to measure the reliability of the test and showed good internal consistency. A 5-hour multisensory program for science teachers was designed and administered at the Instituto de Pesquisas Energéticas e Nucleares (IPEN). The IAT was administered at the beginning and at the end of the program and the results of the implicit associations were compared. After a six-month period, the IAT was re-administered to the same group of teachers to verify whether the implicit associations remained stable. This multisensory program was compared to a 12-week traditional teaching program with lecture classes held at IPEN for incoming post-graduation students. The multisensory program was effective for changing and maintaining the implicit associations of teachers towards the beneficial applications of nuclear technology, unlike the traditional teaching program with lecture classes. This work demonstrated that it is possible to break paradigms and prejudices. The multisensory program enabled an enriched knowledge about the applications of nuclear technology, that is, it promoted new experiences in the explicit memory, which modified the previous associations stored in the implicit memory. Therefore, the multisensory program has proven to be a successful, cost-effective tool, which is able to cause and maintain changes in implicit associations and can be applied in several areas where changes in implicit associations and prejudice reversal are desired. The results demonstrated that the proposed doctoral research was effective, thus contributing to the diffusion of knowledge of the beneficial applications of nuclear technology and, consequently, to its demythification. This methodology may be administered to other fields to identify, modify and/or reduce implicit prejudices or stereotypes.

Trötthet och fördomar : en studie i diskriminering av överviktiga vid mental trötthet / Fatigue and Prejudice : a study of discrimination against the obese in mental fatigueSundlöf, Miriam January 2011 (has links)
Syftet med den här studien var att undersöka om mental trötthet leder till ökad diskriminering av överviktiga. Genom att använda en dual process-modell, inleddes undersökningen med en bedömningsuppgift som deltagarna fick utföra i labbmiljö. Vid ett senare tillfälle fick var och en ombesörja att de genomförde ett implicit associationstest (IAT), följt av en explicit graderingsfråga, där deltagarna uppskattade en eventuell skillnad i normal- kontra överviktigas mentala prestation. Syftet med dessa tester var att ta reda på om diskriminering mot överviktiga existerade inom gruppen i sin helhet på såväl implicit som explicit nivå. Hälften av gruppen hade genomgått en kraftig mental trötthetsbelastning före bedömningsuppgiften, med avsikt att se om bias mot överviktiga ökade vid mental trötthet. Resultatet för alla testningar var för sig visade på diskriminering mot överviktiga, men inte att det förekom någon högre diskriminering vid mental trötthet. Möjliga förbättringar i undersökningsdesignen diskuteras, liksom praktiska implikationer. / This study examined whether mental fatigue leads to increased discrimination against the obese. Using a dual process model, participants took part in an assessment task in a controlled laboratory setting, and thereafter completed an implicit association test (IAT), followed by an explicit question, where participants were asked to grade variances in the mental capacity between normal- versus overweight individuals. The intention was to explore possible obesity discrimination. Half of the group previously completed a strenuous memory task, with the purpose of achieving severe fatigue, in order to explore whether the bias increases with mental fatigue. Although the results revealed discrimination in all tests, there was no evidence of increased discrimination in mental fatigue. Possible improvement in the research design is discussed, as well as practical implications.

Faking the Implicit Association Test (IAT): Predictors, Processes, and DetectionRöhner, Jessica 23 January 2014 (has links)
Unverfälschbarkeit stellt ein wichtiges Gütekriterium psychologischer Testverfahren dar. Dieses Kriterium gilt dann als erfüllt, wenn das Testverfahren auf Grund seiner Konstruktion keine Steuerung oder Verzerrung der Ausprägung von Testwerten seitens der Versuchspersonen ermöglicht (vgl. Moosbrugger & Kelava, 2012).
Im Gegensatz zu direkten Verfahren (z.B. Fragebogen und Interviews), bei welchen die Ausprägung hinsichtlich eines Merkmales durch Selbstbeschreibung der Versuchspersonen erfragt wird und eine Verfälschung (z.B. durch sozial erwünschtes Antwortverhalten) nicht ausgeschlossen werden kann, wurde indirekten Verfahren (z.B. dem Impliziten Assoziationstest; IAT; Greenwald, McGhee, & Schwartz, 1998) lange Zeit Immunität gegen Fälschungsversuche unterstellt. Diese begründet sich unter anderem durch die Annahme, dass mittels indirekter Verfahren implizite Merkmale gemessen werden.
Implizite Merkmale unterscheiden sich von den „eher klassischen“ expliziten Merkmalen, welche vorwiegend mittels direkter Verfahren gemessen werden. Ein wesentlicher Unterschied besteht darin, dass Versuchspersonen nicht notwendigerweise um die Ausprägung hinsichtlich ihrer impliziten Merkmale wissen und dass sie diese Ausprägung auch nicht kontrollieren können (vgl. De Houwer, 2006; De Houwer & Moors, 2007, in press). Die theoretischen Annahmen bezüglich der Eigenschaften impliziter Merkmale bzw. Messergebnisse legen zwei Implikationen nahe. Erstens: Wir können implizite Merkmale ausschließlich über indirekte Zugänge erfassen, da diese nicht notwendigerweise bewusst sind und so eine Selbstauskunft nicht möglich erscheint. Zweitens: Personen können ihre impliziten Messergebnisse nicht kontrollieren und folglich auch nicht verfälschen.
Vermutlich gab es auch aus diesem Grund vor wenigen Jahren einen regelrechten Boom, der zu der Entwicklung einer Vielzahl indirekter Verfahren zur Erfassung impliziter Merkmale geführt hat. Ob jedoch die Messergebnisse dieser Verfahren tatsächlich implizit und damit nicht verfälschbar sind, darf nicht nur theoretisch unterstellt, sondern muss empirisch überprüft werden (vgl. De Houwer, 2006).
Der IAT gilt als das bekannteste, reliabelste und valideste indirekte Verfahren (Bosson, Swan, & Pennebaker, 2000; Rudolph, Schröder-Abé, Schütz, Gregg, & Sedikides, 2008). In meiner
Dissertation habe ich mich aus diesem Grund der empirischen Überprüfung auf Verfälschbarkeit des IATs gewidmet.
Die vorliegende Dissertation besteht aus insgesamt fünf Kapiteln. Das 1. Kapitel bildet eine theoretische Einführung zu den Themen Fälschung im diagnostischen Kontext und zum IAT. Grundlegende Befunde und Fragen zur Verfälschbarkeit des IATs werden dargestellt. Kapitel 2 bis 4 bilden empirische Beiträge meiner Forschung, die sich jeweils schwerpunktmäßig mit unterschiedlichen Aspekten der Verfälschbarkeit des IATs beschäftigen. In Kapitel 2 wird der Frage nachgegangen, unter welchen Bedingungen der IAT verfälschbar ist. Bis dato haben die wenigen existierenden Studien ein sehr widersprüchliches Bild bezüglich der Verfälschbarkeit des IATs aufgezeigt. Ein Grund hierfür könnte sein, dass potentiell relevante Faktoren, welche die Verfälschbarkeit des Verfahrens beeinflussen können, noch nie gemeinsam in einer Studie untersucht wurden. Die vorliegende Studie wurde genau mit diesem Ziel konstruiert und durchgeführt. Die Ergebnisse verweisen auf ein komplexes Zusammenspiel verschiedener Faktoren und zeigen auf, unter welchen Bedingungen der IAT verfälschbar ist. Implikationen dieser Ergebnisse werden kritisch diskutiert. In Kapitel 3 werden die Fragen beantwortet, wie Personen den IAT verfälschen und ob Fälschung im IAT detektierbar ist. Die Forschung hat sich bislang nur bedingt damit beschäftigt, was fälschende Personen tun, um ihre Messergebnisse wie gewünscht zu beeinflussen. Es wurde auch noch nicht untersucht, ob Versuchspersonen unter verschiedenen Bedingungen (z.B. Fälschungsziel: hohe vs. niedrige Testwerte) unterschiedliche Strategien anwenden. Dennoch wurden Indices vorgeschlagen, welche in der Lage sein sollen, Fälschung im IAT zu detektieren (Agosta, Ghirardi, Zogmaister, Castiello, & Sartori, 2011; Cvencek, Greenwald, Brown, Gray, & Snowden, 2010). In der vorgestellten Studie habe ich einerseits untersucht, welche Strategien fälschende Personen anwenden und ob sie, je nach Bedingung, zu unterschiedlichen Strategien greifen. Andererseits habe ich untersucht, welche dieser Strategien tatsächlich mit erfolgreicher Fälschung des IATs einhergehen. Schließlich habe ich untersucht, ob die in der Vergangenheit vorgeschlagenen Indices tatsächlich in der Lage sind, erfolgreiche FälscherInnen zu detektieren. Meine Ergebnisse zeigen, dass fälschende Personen unterschiedliche Strategien anwenden, um ihr Ziel zu erreichen. Damit verbunden zeigte sich auch, dass es schwerer ist als bislang angenommen, erfolgreiche FälscherInnen im IAT zu detektieren. Implikationen dieser Ergebnisse werden kritisch diskutiert. Kapitel 4 beschäftigt sich mit der Frage, ob kognitive Fähigkeiten ein erfolgreiches Fälschen im IAT erleichtern. Bisher wurden diese Fähigkeiten nur mit Fälschungserfolg in direkten Verfahren in Verbindung gebracht (vgl. Hartshorne & May, 1928; Nguyen, Biderman, & McDaniel, 2005; Ones, Viswesvaran, & Reiss, 1996; Pauls & Crost, 2005; Snell, Sydell, & Lueke, 1999; Tett, Freund, Christiansen, Fox, & Coaster, 2012; Weiner & Gibson, 2000). In der vorgestellten Studie habe ich untersucht, ob sie auch beim Fälschen des IATs eine Rolle spielen. Besonders habe ich mich dabei für die Rolle des g Faktors der Intelligenz, der Verarbeitungsgeschwindigkeit und der Konzentrationsfähigkeit interessiert. Die Ergebnisse meiner Studie zeigen auf, dass einige dieser Prädiktoren tatsächlich einen Einfluss auf den Fälschungserfolg im IAT haben. Implikationen dieser Ergebnisse werden kritisch diskutiert. Das 5. Kapitel bildet eine Zusammenführung und Integration der Befunde meiner Forschung in die bestehende Theorie. Zudem werden ein Ausblick für die weitere Forschung sowie Empfehlungen für die Praxis gegeben.
