Can externally activated trait concepts affect person judgments after encoding?,.

Current knowledge accessibility research assumes primed trait concepts to have no biasing effects beyond the encoding stage. In a series of studies, we challenge this assumption. We predict that trait concepts still can influence the person judgments of a predictor who previously stored the target person information through selective retrieval of trait congruent information. Our results consistently reveal assimilation effects when participants are primed with traits at judgment. Moreover, we identify two boundary conditions provide further evidence of the underlying selective retrieval process. First, assimilation effects only occur when stored target person instances apply to the externally activated knowledge and, second, when no prior target person impression is formed.Studies; Prisoner's dilemma game; Real life; Behavior; Altruism; Costly signaling; Research; Judgments; Knowledge; Effects; Information; Processes;

Interpetative thinking and impression formation in a prisoner's dilemma game.

In three experiments we examined the notion that interpretative thinking guides impression formation when playing a prisoner's dilemma game. In a first experiment, we demonstrated that an interpretation goal is spontaneously triggered upon receiving ambiguous information about an interaction partner in the context of a prisoner's dilemma game. In Experiment 2, we examined whether in this context accessible knowledge is used as an interpretation frame for judging the interaction partner. Indeed, we found that subliminally primed extreme person exemplars led to an assimilation effect in person judgment in a prisoner's dilemma game, whereas they led to a contrast effect when person judgments were made in a control condition. Finally in experiment 3, priming a comparison goal before entering a prisoner's dilemma game led participants to use subliminally presented extreme exemplars again as a standard of comparison in the judgment of an interaction partner.Information; Knowledge;

Exploring the role of consistency of social value orientations : temporal stability, reciprocal cooperation, and forgiveness.

Many studies of social interaction have incorporated the nature of social value orientations (pro-social vs. pro-self) as an important factor. This paper extends this literature by showing that the effect of the nature of social value orientations is moderated by the consistency of social value orientations (high vs. low). In three studies, we examined this moderating influence. In Study 1, we investigated the temporal stability of social value orientations and found that high consistent orientations are more stable than low consistent orientations. In Studies 2 and 3, we found evidence for the moderating impact of consistency of social value orientations on reciprocal cooperation and forgiveness. High consistent individuals were more likely to follow the nature of their social value orientation than low consistent individuals.

Do not prime hawks with doves : the impact of dispositions and situation-specific features on the emergence of cooperative behavior in mixed-motive situations.

In four experiments, we examined the impact of the nature and consistency of people's social value orientations on the emergence of cooperative behavior in conditions of neutral, morality or might priming. In line with Van Lange (2000), we expected social value orientations to have a greater impact in ambiguous (neutral priming) than in unambiguous (morality and might priming) situations. We also expected the later moderation to be higher among participants low in consistency (see also Hertel and Fiedler, 1998). Overall, participants' behavior shifted in prime-consistent ways. However, cooperation was reduced among high consistent pro-selfs primed with morality concepts. Experiments 2-4 replicate and generalize these findings, and reveal that high consistent pro-selfs exploited partners believed to be cooperative as a result of morality priming. Implications of these results are discussed in the wider context of interdependence theory, and in the context of automatic behavior effects.

Knowledge Activation After Information Encoding: Implications of Trait Priming on Person Judgment

It is widely assumed that traits primed after the encoding of person information do not lead to assimilation effects on the judgment of that person. The authors challenge this view by providing evidence that post-encoding trait primes can result in assimilative person judgments under certain conditions. In Experiments 1 and 2, we identify the conditions under which these assimilation effects occur. Experiment 1 shows the importance of participants’ goals during person information encoding: assimilation is observed when person information is encoded as part of a memorization goal (as opposed to an impression formation goal). The findings of Experiment 2 further reveal that the encoded person information should imply trait concepts rather than being merely vague with respect to the primed trait category. Finally, the results of Experiment 3 suggest that the obtained assimilation effect is driven by differential accessibility for prime-congruent person information

Improving Food Safety by Using One- and Two-Photon- Induced Fluorescence Spectroscopy for the Detection of Mycotoxins

The presence of mycotoxins in food products is a major worldwide problem. Nowadays, mycotoxins can only be detected by the use of sample-based chemical analyses. Therefore, we demonstrate the use of one- and two-photon-induced fluorescence spectroscopy for the non-destructive detection of mycotoxins in unprocessed food products. We first explain our optical set-up, which is able to measure the localized one- and two-photon-induced fluorescence spectra. Following, as a case study, the detection of aflatoxin in maize kernels is discussed. We present our research methodology, from the characterization of the fluorescence of pure aflatoxin, to the study of the one- and two- photon-induced fluorescence spectra of maize kernels and the development of an optical detection criterion. During both one- and two-photon-induced fluorescence processes, the fluorescence of the aflatoxin influences the intrinsic fluorescence of the maize. Based on the fluorescence spectrum between 400 and 550 nm, a detection criterion to sense the contaminated kernels is defined. Furthermore, we successfully monitored the localized contamination level on the kernel’s surface, showing both contaminated kernels with a high contamination in a limited surface area (a few square millimetres) and kernels with a low contamination spread over a large surface area (up to 20 mm2). Finally, the extensibility of our research methodology to other fluorescent mycotoxins is discussed

About prisoners and dictators: the role of other-self focus, social value orientation, and sterotype primes in shaping cooperative behavior.

Six experiments examined the effects of person factors (i.e., social value orientation and consistency) and situation factors (i.e., stereotype primes) on cooperative behavior in various experimental games. Results indicated that the main and joint influences of person and situation factors on cooperative choices depend on the nature of the game (i.e., prisoner's dilemma or dictator game). Social value orientation, consistency, and primes affect cooperative behavior only in a dictator game, while these factors also lead to rumination about partner's behavioral intentions and personality (and therefore to different cooperative choices) in a prisoner's dilemma game. Differences between these games were explained in terms of the impact they have on other- and self-focus.Choice; Consistency; Dictator game; Effects; Factors; Prisoner's dilemma game; Social Value Orientation; Stereotype Priming; Value;

Effects of Messiness on Preferences for Simplicity

This research examines the effect of experiencing messiness, induced by a messy environment or by priming the concept of messiness, on consumers. We propose that messiness is an aversive state and consumers are motivated to attenuate this state by seeking simplicity in their cognitions, preferences, and choices. Six experiments support our theorizing. Experiments 1a-1c (conducted in the laboratory) and experiment 2 (conducted in the field) demonstrate that when messiness is salient, consumers form simpler product categorizations, are willing to pay more for a t-shirt with a simple picture, and seek less variety in their choices. Experiment 3 brings additional evidence for the underlying role of the need for simplicity by showing that when the need for simplicity is satiated, the effects of messiness disappear. A final experiment shows a boundary condition of the messiness effect: political conservatives are more susceptible to messiness primes compared to liberals
