Perceptual restoration in toddlers

Perception by adults is a constant interaction between the top-down effects of prior knowledge and the effects of bottom-up perceptual information. One obvious example of this interaction is the perceptual restoration effect, in which adult listeners have the illusion that a word is complete when a portion of it has been replaced by a masking noise. In four experiments, we demonstrate that toddlers fail to show the illusion of perceptual restoration, even in constrained situations with words they know quite well. Not only do toddlers have less prior knowledge than do adults, but they also appear to place less reliance on the knowledge that they do have, at least in the paradigm tested here. Instead, toddlers appear to be more tied to the perceptual information they receive than are adults.     

A comparison of statistical selection strategies for univariate and bivariate log‐linear models

In this study, eight statistical selection strategies were evaluated for selecting the parameterizations of log‐linear models used to model the distributions of psychometric tests. The selection strategies included significance tests based on four chi‐squared statistics (likelihood ratio, Pearson, Freeman–Tukey, and Cressie–Read) and four additional strategies (Akaike information criterion (AIC), Bayesian information criterion (BIC), consistent Akaike information criterion (CAIC), and a measure attributed to Goodman). The strategies were evaluated in simulations for different log‐linear models of univariate and bivariate test‐score distributions and two sample sizes. Results showed that all eight selection strategies were most accurate for the largest sample size considered. For univariate distributions, the AIC selection strategy was especially accurate for selecting the correct parameterization of a complex log‐linear model and the likelihood ratio chi‐squared selection strategy was the most accurate strategy for selecting the correct parameterization of a relatively simple log‐linear model. For bivariate distributions, the likelihood ratio chi‐squared, Freeman–Tukey chi‐squared, BIC, and CAIC selection strategies had similarly high selection accuracies.     

The social face of emotion recognition: Evaluations versus stereotypes

The goal of the present paper was to demonstrate the influence of general evaluations and stereotype associations on emotion recognition. Earlier research has shown that evaluative connotations between social category members and emotional expression predict whether recognition of positive or negative emotional expressions will be facilitated (e.g. Hugenberg, 2005). In the current paper we tested the hypothesis that stereotype associations influence emotion recognition processes, especially when the difference between valences of emotional expressions does not come into play. In line with this notion, when participants in the present two studies were asked to classify positive versus negative emotional expressions (i.e. happy versus anger, or happy versus sadness), valence congruency effects were found. Importantly, however, in a comparative context without differences in valence in which participants were asked to classify two distinct negative emotions (i.e. anger versus sadness) we found that recognition facilitation occurred for stereotypically associated discrete emotional expressions. With this, the current results indicate that a distinction between general evaluative and cognitive routes can be made in emotion recognition processes.     

Lateralisation of diffuse positive and negative affect: Ascribing valence to ambiguous stimuli

The available evidence regarding the lateralisation of affect is rather divergent. Interestingly, the common procedure in previous research on affective lateralisation has been to measure hemispheric dominance following exposure to concrete affective stimuli. Therefore, prior research seems to tap primarily into the lateralisation of specific approach–avoidance motivations rather than diffuse affective states. The present research adopted an alternative methodological approach that excluded approach–avoidance motivations and merely studied the lateralised nature of diffuse affect. Participants evaluated ambiguous stimuli presented in either the right or left visual field. Results showed that stimuli presented in the left visual field were significantly more often ascribed a positive meaning compared to information in the right visual field. The present findings are compatible with related lateralised processes and underscore the necessity of distinguishing between specific motivations and diffuse affect.     

Devaluation of distracting stimuli

Previous research has shown that distracting stimuli are evaluated more negatively than new stimuli in a dual task paradigm (Raymond, Fenske, & Tavassoli, 2003). The present research aimed to extend this research by showing that repeatedly selecting targets in a perceptual identification task leads to lower evaluations of distracting stimuli embedded in this task, even when participants are unaware that they will be asked to evaluate the stimuli in a subsequent (separate) task. Results indeed show that repeatedly selecting target stimuli in the presence of distracting stimuli leads to devaluation of these distracting stimuli compared to both target stimuli and new stimuli in a subsequent task. The findings of the present research indicate that devaluation of repeatedly ignored stimuli arises even when stimulus evaluation is not salient during target selection.     

A laboratory analogue of mirrored-self misidentification delusion: The role of hypnosis,suggestion, and demand characteristics

Mirrored-self misidentification is the delusional belief that one’s own reflection in the mirror is a stranger. In two experiments, we tested the ability of hypnotic suggestion to model this condition. In Experiment 1, we compared two suggestions based on either the delusion’s surface features (seeing a stranger in the mirror) or underlying processes (impaired face processing). Fifty-two high hypnotisable participants received one of these suggestions either with hypnosis or without in a wake control. In Experiment 2, we examined the extent to which social cues and role-playing could account for participants’ behaviour by comparing the responses of 14 hypnotised participants to the suggestion for impaired face processing (reals) with those of 14 nonhypnotised participants instructed to fake their responses (simulators). Overall, results from both experiments confirm that we can use hypnotic suggestion to produce a compelling analogue of mirrored-self misidentification that cannot simply be attributed to social cues or role-playing.     

On the nature of attitude–behavior relations: the strong guide,the weak follow

This study investigated the role of attitude strength as a moderator variable with regard to the direction of the relation between attitudes and behavior. The hypothesis was tested that strong attitudes guide behavior, whereas weak attitudes follow behavior in accordance with self‐perception principles. The study (N = 106) consisted of two sessions. In session 1, attitudes and attitude strength (certainty, importance, centrality) towards Greenpeace were measured. One week later, participants returned to the laboratory (session 2) and were given the opportunity to donate money to Greenpeace. After the participants' decision to donate money or not, attitudes towards Greenpeace were measured again. The results were consistent with the predictions. First, strong attitudes were more predictive of donation behavior than weak attitudes. Moreover, session 2 attitudes of weak attitude participants were influenced by their donation behavior, whereas no such effect was found among strong attitude participants. Finally, strong attitudes were also found to be more stable over time than weak attitudes. The results provide a complete overview of the moderating role of attitude strength with regard to the bi‐directional attitude‐behavior relationship. Results are discussed in the light of attitude retrieval versus attitude‐construction processes. Copyright © 2002 John Wiley & Sons, Ltd.     

From repetition to conviction: Attitude accessibility as a determinant of attitude certainty

The present experiment investigated the influence of attitude accessibility on several meta-attitudinal strength measures. It was predicted that certainty and perceived likelihood of change, i.e., commitment-related attributes of attitude strength, are influenced by changes in attitude accessibility, while no effects were expected for importance and perceived centrality to values and the self, i.e., centrality-related attributes. Accessibility was manipulated by having participants express their attitudes either repeatedly or only once. As hypothesized, accessibility and measures of commitment were enhanced after repeated expression compared to single expression. Furthermore, mediation analyses supported the idea that subjective commitment may be inferred from the ease of attitude retrieval. Centrality-related attributes were found to be unaffected by the accessibility manipulation. The results are discussed in the light of a multi-dimensional structure of attitude strength and antecedent processes of meta-cognitive attributes of strength.
