Seeing women as objects: The sexual body part recognition bias

Objectification theory suggests that the bodies of women are sometimes reduced to their sexual body parts. As well, an extensive literature in cognitive psychology suggests that global processing underlies person recognition, whereas local processing underlies object recognition. Integrating these literatures, we introduced and tested the sexual body part recognition bias hypothesis that women's (versus men's) bodies would be reduced to their sexual body parts in the minds of perceivers. Specifically, we adopted the parts versus whole body recognition paradigm, which is a robust indicator of local versus global processing. The findings across two experiments showed that women's bodies were reduced to their sexual body parts in perceivers' minds. We also found that local processing contributed to the sexual body part recognition bias, whereas global processing tempered it. Implications for sexual objectification and its underlying processes and motives are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

“Don't let the group down”: Facets of instrumentality moderate the motivating effects of groups in a field experiment

The motivating effects of group work as compared with individual work are not restricted to the research laboratory but have recently been documented in existing groups performing meaningful tasks. Freestyle swimmers at the 2008 Olympics were shown to swim faster in relay groups than in the individual competitions when their contribution was highly instrumental for the relay group (i.e., indispensable) because of their serial position in the group. The present study replicated and extended this work, aggregating a larger sample from major sports events (N = 199 freestyle swimmers) that also allowed for a competitive test between the instrumentality approach and explanations based on differences in the starting procedures of relay and individual competitions. Consistent with expectancy value models of effort expenditure in groups, swimmers were faster in the relay groups as compared with individual competitions only when (i) a swimmer's performance was highly instrumental for the group's performance (i.e., later serial position in the relay) and (ii) the group's performance was highly instrumental for a positive group outcome (i.e., the relay group had a good chance of winning a medal). The data were not consistent with an explanation of performance differences merely as a result of different starting procedures. Copyright © 2012 John Wiley & Sons, Ltd.     

Talking about visually perceived events: Communication effects on eyewitness memory

Communicators' tuning of a message about a social target to their audience's evaluation can shape their representation of the target. This audience‐tuning effect has been demonstrated with ambiguous text passages as input material. We examined whether the effect also occurs when communicators learn about the target's behaviours from visual (nonverbal) input material. In Experiment 1, participants watched a soundless video depicting ambiguous behaviours of a target, described the video to an audience who liked (vs. disliked) the target, and subsequently recalled the video. Both message and recall were biased towards the audience's judgement. In Experiment 2, the video depicted a forensically relevant event, specifically ambiguous behaviours of two persons involved in a bar brawl. Participants tuned their event retellings to their audience's responsibility judgement and remembered the event accordingly. In both experiments, the effect of the audience's judgement on recall was statistically mediated by the extent to which the message was tuned to the audience. The more participants experienced a shared reality with their audience the stronger was the message‐recall correlation (Experiment 2). We conclude that the audience‐tuning effect for visually perceived information depends on the communicators' creation of a shared reality with their audience.

Increasing perceived variability reduces prejudice and discrimination

We examined whether increasing individuals' perceived variability of an out-group reduces prejudice and discrimination toward its members. In a series of 4 laboratory and field experiments, we attracted participants' attention to either the homogeneity or the heterogeneity of members of an out-group, and then measured their attitudes or behaviors. Perceived variability was manipulated by making subgroups salient, by portraying the out-group members as having diverse opinions, by making salient that out-group members have different characteristics, or by asking participants to think about differences among out-group members. Prejudice and discrimination were measured in terms of self-reported attitudes, distribution of rewards, helping an out-group confederate, and evaluation of an out-group candidate in a simulated hiring decision. In all experiments, perceived variability decreased prejudice and discrimination. This effect may be due to the fact that perceived variability decreases the role of group membership in the production of attitudes and behaviors toward other individuals.     

Gamers against science: The case of the violent video games debate

This article explores the notion that scientific research programs and empirical findings are fundamentally devalued when they threaten a perceiver's social identity. Findings from three studies show the following: (1) identification with the group of “gamers” (i.e., people who play video games on a regular basis) influences the extent to which perceivers devalue research suggesting that playing violent video games has negative consequences; (2) this effect is mediated by the feeling that the group of gamers is being stigmatized by such research (Studies 1 and 2) as well as by anger about this research (Study 2); (3) the effect of in‐group identification on negative research evaluations cannot be explained by attitude or behavioral preference inconsistency (Studies 1 and 3); and (4) strongly identified gamers not only devalue a specific scientific study but also generalize their negative evaluations to the entire field of violent video games research (Study 3). The findings suggest that the influence of social identity processes on the evaluation of research is larger than it has previously been recognized. Implications of these findings for science communication are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Children prenatally exposed to maternal anxiety devote more attentional resources to neutral pictures

Maternal anxiety during pregnancy can negatively affect fetal neurodevelopment, predisposing the offspring to a higher risk of behavioral and emotional problems later in life. The current study investigates the association between maternal anxiety during pregnancy and child affective picture processing using event‐related brain potentials (ERPs). Mothers reported anxiety during the second trimester using the anxiety subscale of the Symptom Checklist (SCL‐90). At age 4 years, child affective picture processing (N = 86) was measured by recording ERPs during viewing of neutral, pleasant, and unpleasant pictures selected from the International Affective Pictures System. The late positive potential (LPP)—an ERP component reflecting individual differences in affective processing—was used as child outcome. The expected positive association between maternal anxiety and LPP amplitude for unpleasant pictures was not found. Nevertheless, we found a positive association between maternal anxiety during pregnancy and LPP amplitudes for neutral pictures in the middle and late time window at anterior locations (all p < .05). These associations remained significant after adjusting for maternal postnatal anxiety and gestational age at birth and after FDR correction for multiple comparisons. Our study provides neurophysiological evidence that children prenatally exposed to higher maternal anxiety devote more attentional resources to neutral pictures, but not to unpleasant pictures. Possibly, these children show enhanced vigilance for threat when viewing neutral pictures. Although useful in dangerous environments, this enhanced vigilance may predispose children prenatally exposed to higher maternal anxiety to developing behavioral and/or emotional problems later in life.

Ocular signatures of proactive versus reactive cognitive control in young adults

During the execution of a cognitive task, the brain maintains contextual information to guide behavior and achieve desired goals. The AX-Continuous Performance Task is used to study proactive versus reactive cognitive control. Young adults tend to behave proactively in standard testing conditions. However, it remains unclear how interindividual variability (e.g., in cognitive and motivational factors) may drive people into more reactive or proactive control under the same task demands. We investigated the use of control strategies in a large population of healthy young adults. We computed the proactive behavioral index and consequently divided participants into proactive, reactive, and intermediate groups. We found that reactive participants were generally slower, presented lower context sensitivity, and larger response variability. Pupillary changes and blink rate index cognitive effort allocation. We measured, concomitantly to the task, the pupil size and frequency of blinks associated with the cue maintenance and response intervals. During the cue period, nonfrequent, nontarget cues led to increased pupil dilation and number of blinks in all participants. During the response interval, we found more errors and increased pupil dilation to the probe when all participants had to overcome a response bias generated by the frequent cue. Only reactive participants showed larger response-related pupil when they had to overcome a response bias related to the frequent probe. Contrary to expectations, groups did not differ in ocular measures in the cue period. In conclusion, interindividual differences in cognitive control between healthy adults can be mapped onto different patterns of effort allocation indexed by the pupil.     

Neurocognitive mechanisms behind emotional attention: Inverse effects of anodal tDCS over the left and right DLPFC on gaze disengagement from emotional faces

Background

Attention to relevant emotional information in the environment is an important process related to vulnerability and resilience for mood and anxiety disorders. In the present study, the effects of left and right dorsolateral prefrontal cortex (i.e., DLPFC) stimulation on attentional mechanisms of emotional processing were tested and contrasted.

Methods

A sample of 54 healthy participants received 20 min of active and sham anodal transcranial direct current stimulation (i.e., tDCS) either of the left (n = 27) or of the right DLPFC (n = 27) on two separate days. The anode electrode was placed over the left or the right DLPFC, the cathode over the corresponding contra lateral supraorbital area. After each neurostimulation session, participants completed an eye-tracking task assessing direct processes of attentional engagement towards and attentional disengagement away from emotional faces (happy, disgusted, and sad expressions).

Results

Compared to sham, active tDCS over the left DLPFC led to faster gaze disengagement, whereas active tDCS over the right DLPFC led to slower gaze disengagement from emotional faces. Between-group comparisons showed that such inverse change patterns were significantly different and generalized for all types of emotion.

Conclusions

Our findings support a lateralized role of left and right DLPFC activity in enhancing/worsening the top-down regulation of emotional attention processing. These results support the rationale of new therapies for affective disorders aimed to increase the activation of the left over the right DLPFC in combination with attentional control training, and identify specific target attention mechanisms to be trained.

     

Beliefs about group malleability and out‐group attitudes: The mediating role of perceived threat in interactions with out‐group members

Recent research suggests that inducing fixed (rather than malleable) beliefs about groups leads to more negative attitudes toward out‐groups. The present paper identifies the underlying mechanism of this effect. We show that individuals with a fixed belief about groups tend to construe intergroup settings as threatening situations that might reveal shortcomings of their in‐group (perceived threat). In the present research, we measured (Study 1) and manipulated (Study 2) participants' lay theories about group malleability. We found that the extent to which individuals had an entity (versus an incremental) group theory influenced the level of threat they felt when interacting with out‐group members, and that perceived threat in turn affected their level of ethnocentrism and prejudice. These findings shed new light on the role of lay theories in intergroup attitudes and suggest new ways to reduce prejudice. Copyright © 2015 John Wiley & Sons, Ltd.
