Alienable Speech: Ideological Variations in the Application of Free-Speech Principles

Although freedom of speech is a Constitutionally protected and widely endorsed value, political tolerance research finds that people are less willing to protect speech they dislike than speech they like ( Gibson, 2006 ). Research also suggests liberal-conservative differences in political tolerance ( Davis & Silver, 2004 ). We measured U.S. citizens' political tolerance for speech acts, while manipulating the speaker's ethnicity and the speech's ideological content. Speech criticizing Americans was protected more strongly than was speech criticizing Arabs, especially among more politically liberal respondents. Liberals also reported greater free-speech support. Respondents expressed greater political tolerance for a speaker when he was an exemplar of the criticized group, but showed equal political tolerance for speakers whose group membership (as a White or Black American) was irrelevant to the speech. Finally, implicit political identity showed convergent validity with explicit political identity in predicting speech tolerance, and implicit racial and ethnic preferences showed variable prediction of speech tolerance across the two studies.     

Too tired to tell the truth: Self-control resource depletion and dishonesty

The opportunity to profit from dishonesty evokes a motivational conflict between the temptation to cheat for selfish gain and the desire to act in a socially appropriate manner. Honesty may depend on self-control given that self-control is the capacity that enables people to override antisocial selfish responses in favor of socially desirable responses. Two experiments tested the hypothesis that dishonesty would increase when people’s self-control resources were depleted by an initial act of self-control. Depleted participants misrepresented their performance for monetary gain to a greater extent than did non-depleted participants (Experiment 1). Perhaps more troubling, depleted participants were more likely than non-depleted participants to expose themselves to the temptation to cheat, thereby aggravating the effects of depletion on cheating (Experiment 2). Results indicate that dishonesty increases when people’s capacity to exert self-control is impaired, and that people may be particularly vulnerable to this effect because they do not predict it.     

Entitativity and prejudice: Examining their relationship and the moderating effect of attitude certainty

Previous research suggests that perceived entitativity, which represents the degree to which groups are perceived to possess unity, coherence, and organization, predicts intergroup stereotyping and bias. The present research yielded complementary evidence that prejudice (toward Muslims in Study 1 and toward South Asians in Study 2) can also predict groups’ perceived entitativity. In particular, Study 1 found that the relationships of two predictors, intergroup contact and social dominance orientation, with perceived entitativity were mediated by prejudice. Study 2 demonstrated, as predicted, that this set of relationships occurred primarily for intergroup attitudes of relatively high certainty. Neither study found support for models in which entitativity mediated the relationships of the predictors with prejudice. Conceptual and analytical factors that may account for evidence of the potential bi-directionality of the bias-entitativity relationship are considered.     

Religious Fundamentalism as Schema: Influences on Memory for Religious Information

Those with differing levels of religious fundamentalism (RF) may be selective in their memory for religious information. In Study 1, participants read a text about money or sex, with a judgmental or not-judgmental message. Higher RF was associated with more accurate recall and fewer intrusions. In Study 2, participants high or low in RF read texts about sex. High-RF participants had more accurate recall and fewer intrusions. However, high-RF participants had more recognition false alarms to sentences that were not presented. High RF may aid memory for religious information, but also increase familiarity of related but not presented information. Exposure to not-judgmental messages decreased RF scores, suggesting that textual messages can impact responses to fundamentalism scales.     

Food cue exposure and body image satisfaction: the moderating role of BMI and dietary restraint

Effects of cue exposure to high and low-caloric food on body image satisfaction and the moderating role of body mass index (BMI) and restraint were investigated in 77 lean unrestrained, lean restrained and overweight restrained females. Body (BS) and weight satisfaction (WS) were assessed before and after the cue exposure. Lean restrained participants were significantly less satisfied with their weight after cue exposure to high-caloric foods in comparison to cue exposure to low-caloric foods, whereas no such effect was present in overweight restrained and lean unrestrained participants. Low-caloric food cues did not influence WS. Food cues had a nonsignificant trend effect on BS. Yet, only lean unrestrained participants experienced significantly more BS in response to food cue exposure.     

The Irony of Harmony: Intergroup Contact Can Produce False Expectations for Equality

ABSTRACT— Positive intergroup contact has been a guiding framework for research on reducing intergroup tension and for interventions aimed at that goal. We propose that beyond improving attitudes toward the out-group, positive contact affects disadvantaged-group members' perceptions of intergroup inequality in ways that can undermine their support for social change toward equality. In Study 1, participants were assigned to either high- or low-power experimental groups and then brought together to discuss either commonalities between the groups or intergroup differences. Commonality-focused contact, relative to difference-focused contact, produced heightened expectations for fair (i.e.,  egalitarian) out-group behavior among members of disadvantaged groups. These expectations, however, proved unrealistic when compared against the actions of members of the advantaged groups. Participants in Study 2 were Israeli Arabs (a disadvantaged minority) who reported the amount of positive contact they experienced with Jews. More positive intergroup contact was associated with increased perceptions of Jews as fair, which in turn predicted decreased support for social change. Implications for social change are considered.     

More Than Just IQ: School Achievement Is Predicted by Self-Perceived Abilities—But for Genetic Rather Than Environmental Reasons

ABSTRACT— Evidence suggests that children's self-perceptions of their abilities predict their school achievement even after one accounts for their tested cognitive ability (IQ). However, the roles of nature and nurture in the association between school achievement and self-perceived abilities (SPAs), independent of IQ, is unknown. Here we reveal that there are substantial genetic influences on SPAs and that there is genetic covariance between SPAs and achievement independent of IQ. Although it has been assumed that the origins of SPAs are environmental, this first genetic analysis of SPAs yielded a heritability of 51% in a sample of 3,785 pairs of twins, whereas shared environment accounted for only 2% of the variance in SPAs. Moreover, multivariate genetic analyses indicated that SPAs predict school achievement independently of IQ for genetic rather than environmental reasons. It should therefore be possible to identify "SPA genes" that predict school achievement independently of "IQ genes."     

The Relation of Parental Guilt Induction to Child Internalizing Problems When a Caregiver Has a History of Depression

The purpose of this study was to examine the relation between parental guilt induction and child internalizing problems in families where a caregiver had experienced depression. A total of 107 families, including 146 children (age 9–15), participated. Child-reported parental guilt induction, as well as three more traditionally studied parenting behaviors (warmth/involvement, monitoring, and discipline), were assessed, as was parent-report of child internalizing problem behavior. Linear Mixed Models Analysis indicated parental guilt induction was positively related to child internalizing problems in the context of the remaining three parenting behaviors. Implications of the findings for prevention and intervention parenting programs are considered.     

Race-based perceptual asymmetries underlying face processing in infancy

Adults process other-race faces differently than own-race faces. For instance, a single other-race face in an array of own-race faces attracts Caucasians’ attention, but a single own-race face among other-race faces does not. This perceptual asymmetry has been explained by the presence of an other-race feature in other-race faces and its absence in own-race faces; this difference is thought to underlie race-based differences in face processing. We examined the developmental origins of this mechanism in two groups of Caucasian 9-month-olds. Infants in the experimental group exhibited a preference for a pattern containing a single Asian face among seven Caucasian faces over a pattern containing a single Caucasian face among seven Asian faces. This preference was not driven by the majority of elements in the images, because a control group of infants failed to exhibit a preference between homogeneous patterns containing eight Caucasian versus eight Asian faces. The results demonstrate that an other-race face among own-race faces attracts infants’ attention but not vice versa. This perceptual asymmetry suggests that the other-race feature is available to Caucasians by 9 months of age, thereby indicating that mechanisms of specialization in face processing originate early in life.     

Growth and pruning of mushroom body Kenyon cell dendrites during worker behavioral development in the paper wasp, Polybia aequatorialis (Hymenoptera: Vespidae)

Adult workers of some social insect species show dramatic behavioral changes as they pass through a sequence of task specializations. In the paper wasp, Polybia aequatorialis, female workers begin adult life within the nest tending brood, progress to maintaining and defending the nest exterior, and ultimately leave the nest to forage. The mushroom body (MB) calyx neuropil increases in volume as workers progress from in-nest to foraging tasks. In other social Hymenoptera (bees and ants), MB Kenyon cell dendrites, axons and synapses change with the transition to foraging, but these neuronal effects had not been studied in wasps. Furthermore, the on-nest worker of Polybia wasps, an intermediate task specialization not identified in bees or ants, provides the opportunity to study pre-foraging worker class transitions. We asked whether Kenyon cell dendritic arborization varies with the task specialization of Polybia workers observed in the field near Monteverde, Costa Rica. Golgi-impregnated arbors in the lip and collar calyces, which receive a predominance of olfactory and visual input, respectively, were quantified using Sholl’s concentric circles and a novel application of virtual spherical probes. Arbors of the lip varied in a manner reminiscent of honeybees, with foragers having the largest and in-nest workers having the smallest arbors. In contrast, arbors of the collar were largest in foragers but smallest in on-nest workers. Thus, progression through task specializations in P. aequatorialis involves subregion specific dendritic growth and regression in the MB neuropil. These results may reflect the sensitivity of Kenyon cell dendritic structure to specialization dependent social and sensory experience.
