The Hostile Media Effect,Biased Assimilation,and Perceptions of a Presidential Debate1

This study examined the relation between 2 seemingly inconsistent phenomena: hostile media effect and biased assimilation. Participants (N = 156) reported their preference for George W. Bush or John Kerry and then viewed a live broadcast of the first Bush–Kerry Presidential debate. Consistent with biased assimilation, candidate preference influenced participants on both sides to perceive their candidate won the debate. Nevertheless, candidate preference modestly induced participants to perceive hostile bias from the debate moderator, Jim Lehrer. The influence of anticipated third‐person effects was also examined. Overall, the results suggest biased assimilation and the hostile media effect are not inconsistent. In some situations, they occur simultaneously. Moreover, the hostile media effect appears to extend beyond news reports to other forms of mediation.     

Left frontal cortical activation and spreading of alternatives: tests of the action-based model of dissonance

The action-based model of dissonance predicts that following decisional commitment, approach-oriented motivational processes occur to assist in translating the decision into effective and unconflicted behavior. Therefore, the modulation of these approach-oriented processes should affect the degree to which individuals change their attitudes to be more consistent with the decisional commitment (spreading of alternatives). Experiment 1 demonstrated that a neurofeedback-induced decrease in relative left frontal cortical activation, which has been implicated in approach motivational processes, caused a reduction in spreading of alternatives. Experiment 2 manipulated an action-oriented mindset following a decision and demonstrated that the action-oriented mindset caused increased activation in the left frontal cortical region as well as increased spreading of alternatives. Discussion focuses on how this integration of neuroscience and dissonance theory benefits both parent literatures.     

Tracking the time course of phonetic cue integration during spoken word recognition

Speech perception requires listeners to integrate multiple cues that each contribute to judgments about a phonetic category. Classic studies of trading relations assessed the weights attached to each cue but did not explore the time course of cue integration. Here, we provide the first direct evidence that asynchronous cues to voicing (/b/ vs. /p/) and manner (/b/ vs. /w/) contrasts become available to the listener at different times during spoken word recognition. Using the visual world paradigm, we show that the probability of eye movements to pictures of target and of competitor objects diverge at different points in time after the onset of the target word. These points of divergence correspond to the availability of early (voice onset time or formant transition slope) and late (vowel length) cues to voicing and manner contrasts. These results support a model of cue integration in which phonetic cues are used for lexical access as soon as they are available.     

Consequences of enactment and concealment for felt authenticity: Understanding the effects of stigma through self-distancing and motive fulfillment

Grounded in Motivated Identity Construction Theory and Self-Determination Theory, two studies examined the consequences of identity enactment and concealment for motive fulfillment and explored how these mediate the negative effects of stigmatized identities on felt authenticity. Participants (Ns = 343 and 344) reported the extent to which they had enacted and/or concealed 8 to 12 of their identities in the past 3 days and evaluated their motive fulfillment and felt authenticity. Using multilevel modeling, we found that identity enactment positively predicted felt authenticity via motive satisfaction, while concealment negatively predicted authenticity via thwarted motive satisfaction. Identities were coded with respect to stigmatization in Study 2 and stigmatized identities felt relatively less authentic, with effects mediated through suppressed enactment, heightened concealment, and thwarted motives. Thus, stigmatized identities do not inherently feel less authentic, rather it is individuals’ self-distancing behaviors that impair feelings of authenticity for a stigmatized identity.

Load effects in attention: Comparing tasks and age groups

Attention is limited in terms of both capacity (i.e., amount of information attended) and selectivity (i.e., the degree to which non-attended information is nonetheless processed). One of the seminal theories in the field, load theory, predicts that these two aspects of attention interact in systematic ways. Specifically, load theory predicts that when the amount of information to attend is less than the available capacity, spare attention will naturally leak out to unattended items. While load theory has found a great deal of empirical support, the robustness of the findings has recently been called into question, in particular with respect to the extent to which the predictions are borne out across different tasks and populations. Here we report tests of perceptual load effects in two different tasks (change detection and enumeration) and in two populations (adults and 7- to 8-year-old children). Adults’ accuracies did not demonstrate the predicted interaction between the capacity and selection dimensions, whereas children’s performance, in addition to being overall worse than adults, did show the interaction. The overall lower accuracy of children was seen to be the result of a larger performance decrement in response to capacity demands, distracting information, and their interaction. Interestingly, while these results were seen at the level of the two tasks, there was no within-participants correlation across tasks. Overall, these results suggest that maturation-related changes attenuate the magnitude of distractor effects in attention, which in turn limits the evidence for interactions between capacity and selection in high-functioning populations.
