Impact of choice set complexity on decoy effects
Studies of contextual choice typically use three option choice sets to evaluate how preference relations depend on the values of a third decoy option. However, often real‐world decisions are made using choice sets with many more than three alternatives, such as in online shopping. Three experiments tested for attraction and compromise decoy effects in choice sets that varied the number and ordering of alternatives using a within‐subjects preferen…

Evaluating non-affective cross-modal congruence effects on emotion perception
Although numerous studies have shown that people are more likely to integrate consistent visual and auditory signals, the role of non-affective congruence in emotion perception is unclear. This registered report examined the influence of non-affective cross-modal congruence on emotion perception. In Experiment 1, non-affective congruence was manipulated by matching or mismatching gender between visual and auditory modalities. Participants were in…
Crossmodal negativity bias in semantic processing
Negative events have greater influence on cognitive processing compared with positive events, a phenomenon referred to as the negativity bias. Previous studies have shown that reaction times (RTs) to negatively valenced items are slower in semantic tasks. According to the automatic vigilance hypothesis, these effects are caused by preferential attention to negative stimuli or features diverting cognitive resources away from semantic processing. H…
Measuring school‐related subjective well‐being in adolescents
The tripartite model of subjective well-being (SWB) incorporates 3 components: frequent positive emotions, infrequent negative emotions, and an overall positive evaluation of life circumstances (Diener, Suh, Lucas, & Smith, 1999). In light of the large amount of time that youth spend in school, this study investigated a tripartite model of school-related SWB among adolescents, based on 3 measures of SWB appropriate for adolescents. The measures i…
Probabilistic reasoning in prediction and diagnosis
In prediction, subset relations require that the probability of conjoined events is never higher than that of constituent events. However, people's judgments regularly violate this principle, producing conjunction errors. In diagnosis, the probability of a hypothesis normatively is often higher for conjoined cues. An online survey used a within‐subjects design to explore the degree to which participants ( n = 347) differentiated diagnosis and pre…
Testing alternative explanations of phantom decoy effects
Phantom decoys are alternatives that asymmetrically dominate a targeted alternative and yet lead to increased selection of the target when the decoy is declared to be unavailable. This effect is difficult to explain within most standard theoretical accounts of decoy effects. The current experiments tested between three explanations of this effect: (1) the relative advantage model based on loss aversion, (2) similarity substitution, and (3) range …
Reference Price and Price Perceptions
Reference price effects on consumer price perceptions are often explained by Helson's adaptation-level theory, in which the cognitive representation of reference price is the prototype of the relevant category. However, recent conceptualizations and empirical evidence suggest the possibility of an exemplar model, which may be specified using Volkmann's range theory or Parducci's range-frequency theory. In two experiments, these three contextual m…
Validity Issues in the Likert and Thurstone Approaches to Attitude Measurement
This article highlights the theoretical differences between the Likert and Thurstone approaches to attitude measurement and demonstrates how such differences can lead to discrepant attitude estimates for individuals with the most extreme opinions. Both simulated data and real data on attitude toward abortion are used to demonstrate this discrepancy. The results suggest that attitude researchers should, at the very least, devote more attention to …
Context Effects on Similarity Judgments of Multidimensional Stimuli
Contextual contrast in evaluative judgments
Two experiments examined at what stage contrast effects occur within the impression-formation process.University students rated the likability of persons described by 5 trait adjectives, with the distribution of trait adjectives manipulated between Ss.Theoretically, contextual stimuli may affect the valuation of component traits before integration, a preintegration model, or they may affect the valuation of the composite impression after the comp…
The self and social judgment
Ss who differed in the extremity of self-definition ("own position") with respect to a given trait (sociability, independence, or patience) made trait and evaluative judgments of behavioral stimuli that varied in their descriptive implications for that trait. Across 4 experiments, individual differences in trait ratings of unambiguous information were mediated largely by differences in Ss' affective reactions to these stimuli rather than by direc…

Intrapersonal and social comparison determinants of happiness
The category effect in social judgment
Three experiments demonstrated the applicability of a range-frequency analysis to social judgments. Subjects rated the happiness of either (a) schematic drawings of faces or (b) life events as expressed in short verbal descriptions. The relative frequency of these stimuli was manipulated experimentally, as was the number of rating categories. Consistent with psychophysical research, ratings became less sensitive to differences in the frequencies …
