In most of these studies, participants were allowed to search for as many pieces of information as they liked. However, in many situations, the amount of information that people can search for is restricted. We report four experiments addressing this issue. Experiment 1 suggests that objective limits regarding the maximum number of pieces of information the participants could search for increases the preference for selecting supporting over conflicting information. In Experiment 2, just giving participants a cue about information scarcity induces the same effect, even in the absence of any objective restrictions. Finally, Experiment 3 and 4 clarify the underlying psychological process by showing that information limits increase selective exposure to information because information search is guided by the expected information quality, which is basically biased towards supporting information, and information limits act to reinforce this tendency"],["dc.identifier.doi","10.1002/ejsp.264"],["dc.identifier.gro","3151540"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8348"],["dc.language.iso","en"],["dc.notes.status","public"],["dc.notes.submitter","chake"],["dc.relation.issn","0046-2772"],["dc.title","Selective exposure to information: the impact of information limits"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Auf Grundlage des von Karsten und Lewin formulierten sowie von Schulz-Hardt, Rott, Meinken und Frey (in Druck) präzisierten Sättigungskonzepts wird postuliert, daß schwer peripherisierbare (d. h. als weitgehend unbewußte Nebenhandlung ausführbare) sowie persönlich relevante Tätigkeiten in höherem Ausmaß zu Sättigung führen sollten als leicht peripherisierbare sowie persönlich wenig relevante Tätigkeiten. Dies wurde in einem Experiment mit 66 Schülern überprüft, die verschiedene Variationen des Konzentrations-Leistungs-Tests (KLT) bearbeiteten. Die Ergebnisse bestätigen weitgehend unsere Vorhersage. Zudem finden sich Hinweise darauf, daß der Zusammenhang zwischen Sättigung und Leistung durch die Peripherisierbarkeit sowie die persönliche Relevanz der Aufgabe moderiert wird."],["dc.description.abstract","The present experiment on the phenomenon of psychic satiation expands on the work of Karsten (1928) and Lewin (1928). Psychic satiation denotes a loss of intrinsic motivation when the same action is performed repeatedly. Although many studies have shown the high theoretical and practical relevance of this phenomenon, the conditions which lead to or reinforce psychic satiation have rarely been investigated empirically. Based on the concept of psychic satiation as formulated by Karsten and Lewin and refined by Schulz-Hardt, Rott, Meinken, and Frey (in press), we predicted that psychic satiation will increase if the task does not lend itself to being carried out “peripherally¾ (i.e., as an almost unconscious incidental action) and if it has high personal relevance. These predictions were investigated in an experiment with 66 high-school students who performed different versions of the “Konzentrations-Leistungs-Test¾ (concentration-performance-test, KLT). The results are largely in line with our predictions. In addition, the results indicate that the relation between satiation and performance is moderated by personal relevance and the induced task characteristic."],["dc.identifier.doi","10.1026//0949-3946.48.3.188"],["dc.identifier.gro","3151526"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8332"],["dc.language.iso","de"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","1618-3169"],["dc.title","Psychische Sättigung: Eine neue experimentelle Untersuchung zu einem alten Konstrukt"],["dc.type","journal_article"],["dc.type.internalPublication","no"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

In a two-factorial experiment with 201 employees and managers from various economic and public organizations, genuine and contrived dissent were investigated as counterstrategies to biased information seeking. Genuine dissent was manipulated by forming three-person groups whose members either all favored the same alternative individually (homogeneous groups) or consisted of a minority and a majority faction with regard to their favored alternative (heterogeneous groups). Contrived dissent was varied by the use or nonuse of the “devil's advocacy” technique.
