Impact of intention on the ERP correlates of face recognition

The present study investigated the impact of study-test similarity on face recognition by manipulating, in the same experiment, the expression change (same vs. different) and the task-processing context (inclusion vs. exclusion instructions) as within-subject variables. Consistent with the dual-process framework, the present results showed that participants performed better on the inclusion task than on the exclusion task, with no response bias. A mid-frontal FN400 old/new effect and a parietal old/new effect were found in both tasks. However, modulations of the ERP old/new effects generated by the expression change on recognized faces differed across tasks. The modulations of the ERP old/new effects were proportional to the degree of matching between the study face and the recognition face in the inclusion task, but not in the exclusion task. The observed modulation of the FN400 old/new effect by the task instructions when familiarity and conceptual priming were kept constant indicates that these early ERP correlates of recognition depend on voluntary task-related control. The present results question the idea that FN400 reflects implicit memory processes such as conceptual priming and show that the extent to which the FN400 discriminates between conditions depends on the retrieval orientation at test. They are discussed in relation to recent controversies about the ERP correlates of familiarity in face recognition. This study suggests that while both conceptual and perceptual information can contribute to the familiarity signal reflected by the FN400 effect, their relative contributions vary with the task demands.     

Body Surveillance and Body Shame in College Men: Are Men Who Self-Objectify Less Hopeful?

The current study examined self-objectification and hope in a sample of undergraduate men from a Midwestern university in the United States (N?=?227). Specifically, an online survey utilizing self-report measures examined the associations between body surveillance, body shame, trait hope, social relationship hope, and romantic relationship hope were considered through the lenses of Objectification Theory and the Broaden and Build Theory of Positive Emotions. Consistent with Hypothesis 1, bivariate correlations showed that more body surveillance was associated with less trait agency, less trait pathways, less social relationship pathways, and less romantic relationship pathways. As well, more body shame was associated with less trait agency, less trait pathways, less social relationship pathways, less romantic relationship agency, and less romantic relationship pathways. Additionally, consistent with Hypothesis 2 and the model proposed by Objectification Theory, body shame explained relations between body surveillance and hope, specifically, trait agency, social relationship pathways, romantic relationship agency, and romantic relationship pathways in a path analysis. This work fills an important gap in the current literature, as it is the only study to date that examines relations between self-objectification and hope, and furthers objectification research among men. Results are discussed within the context of Objectification Theory and the Broaden and Build Theory of Positive Emotions. Implications and future directions are discussed.     

Just Think About It: Mindfulness, Sexism, and Prejudice Toward Feminists

This study examined the relation between mindfulness, sexist motivations and beliefs, and prejudice toward women who violate traditional gender roles—namely feminists. In a preliminary study, 672 (251 men, 421 women) undergraduates from a United States Midwestern university completed a measure of mindfulness and warmth toward feminists and consistent with hypotheses, more mindfulness was associated with more warmth toward feminists. Extending this initial finding to the main study, 653 (273 men, 380 women) undergraduates from a U.S. Midwestern university completed measures of mindfulness, motivation to respond without sexism, ambivalent sexism, and warmth toward feminists. Consistent with hypotheses, compared to women participants, men participants were lower on internal motivation to respond without sexism, higher on hostile and benevolent sexism and less warm toward feminists. Also consistent with hypotheses, for men participants, more mindfulness was associated with higher internal motivation to respond without sexism, less benevolent sexism, and more warmth toward feminists. In contrast, for women participants, more mindfulness was only associated with less hostile sexism. Finally, a path analysis revealed that the positive relation between mindfulness and warmth toward feminists for men participants was partially mediated by more internal motivation to respond without sexism (i.e., a significant indirect effect), but not by less sexist beliefs. Implications for mindfulness, sexism, and prejudice more generally are discussed.     

Low-Cut Shirts and High-Heeled Shoes: Increased Sexualization Across Time in Magazine Depictions of Girls

Theory and past research predict an increase in the sexualization of girls in United States culture. We used content analysis to examine change in the number of sexualizing characteristics (e.g., low cut shirts, high-heeled shoes) and childlike characteristics (e.g., polka-dot print, Mary-Jane style shoes) present in depictions of girls across time in the magazines Seventeen (N?=?1649 images from issues in selected issues from 1971 through 2011) and Girls’ Life (N?=?763 images from selected issues from 1994 to 2011). One-way ANOVAS revealed increases in the total number of sexualizing characteristics across time in both magazines. In particular, depictions of low-cut tops and tight fitting clothing increased in both magazines. There was also a decrease in the number of childlike characteristics in Girls’ Life across time. Possible reasons for increased sexualization as well as possible consequences are discussed.     

The accuracy of ‘haptically’ measured geographical slant perception

In two recent issues of Acta, the widely accepted view of Proffitt (2006), that ‘haptic’ measures of perceived geographical slant are generally accurate, and dissociated from explicit overestimates, came under intense scrutiny (Durgin, Hajnal, Li, Tonge, and Stigliani, 2010; 2011). Durgin and colleagues' challenge to this account centred on the claim that Proffitt's haptic’ measure of geographical slant, the palm-board, may be accidently accurate due to restricted movements available at the wrist. Two experiments reported here compare the accuracy of Proffitt's palm-board with an alternative measure of geographical slant perception, the Palm-Controlled Inclinometer (PCI), which allows participants to use wrist, elbow and shoulder movements to match slant with their hand. Participants (N = 320) made slant judgements using both measures, across five hills and five staircases with 32 participants for each stimulus angle (4.5°–31°). Results for the palm-board replicated those of Proffitt and co-workers, overestimation at shallow angles (≤ 14°), contrasted with underestimation at steeper angles (≥ 23°), whereas estimates made using the PCI had a greater degree of accuracy for steeper slopes. A follow-up experiment tested the accuracy of the palm-board and PCI for surfaces in near space to repeat the design of Durgin et al. (2010, experiment 1). Participants (N = 20) used the palm-board and PCI to judge the angle of slanted blocks (25°, 30°). As with traversable slopes, PCI judgements did not differ from the actual angle of the blocks whereas the palm-board measure underestimated. ‘Haptic’ measures of geographical slant perception can be accurate for relatively steep slopes, in both near and far space.     

How do students improve their value-based learning with task experience?

When learning items that vary in reward, students improve their scores (i.e., earned reward) with task experience. In four experiments, we examined whether such improvements arise from better selective encoding of items that would earn more (vs. less) reward. Participants studied and recalled words across multiple study-test trials. On each trial, 12 words were slated with different values (typically from 1 to 12), and participants earned the point value assigned to a given word if it was correctly recalled. In all experiments, participants earned more points across the first two trials. In Experiment 1, participants either self-paced their study or had experimenter-paced study and in Experiment 2, some participants were penalised for each second spent during study. Improvements in points earned were related to increases in overall recall but not to selective encoding. In Experiment 3, some participants were given value-emphasised instructions, yet they did not demonstrate selective encoding. In Experiment 4, we used a larger range of point values, but selective encoding still did not account for the improvement in point scores across lists. These results suggest that metacognitively-driven selective encoding is not necessary to observe improvements in value-based learning.     

The selective power of causality on memory errors

We tested the influence of causal links on the production of memory errors in a misinformation paradigm. Participants studied a set of statements about a person, which were presented as either individual statements or pairs of causally linked statements. Participants were then provided with causally plausible and causally implausible misinformation. We hypothesised that studying information connected with causal links would promote representing information in a more abstract manner. As such, we predicted that causal information would not provide an overall protection against memory errors, but rather would preferentially help in the rejection of misinformation that was causally implausible, given the learned causal links. In two experiments, we measured whether the causal linkage of information would be generally protective against all memory errors or only selectively protective against certain types of memory errors. Causal links helped participants reject implausible memory lures, but did not protect against plausible lures. Our results suggest that causal information may promote an abstract storage of information that helps prevent only specific types of memory errors.     

When the face fits: Recognition of celebrities from matching and mismatching faces and voices

The results of two experiments are presented in which participants engaged in a face-recognition or a voice-recognition task. The stimuli were face–voice pairs in which the face and voice were co-presented and were either “matched” (same person), “related” (two highly associated people), or “mismatched” (two unrelated people). Analysis in both experiments confirmed that accuracy and confidence in face recognition was consistently high regardless of the identity of the accompanying voice. However accuracy of voice recognition was increasingly affected as the relationship between voice and accompanying face declined. Moreover, when considering self-reported confidence in voice recognition, confidence remained high for correct responses despite the proportion of these responses declining across conditions. These results converged with existing evidence indicating the vulnerability of voice recognition as a relatively weak signaller of identity, and results are discussed in the context of a person-recognition framework.     

Towards a Marine Mindset: Visiting an Aquarium Can Improve Attitudes and Intentions Regarding Marine Sustainability

ABSTRACT

The oceans are crucial for human survival, yet they are under serious threat from humans, for example through overfishing and poor waste management. We investigated two questions. First, does a leisure visit to an aquarium improve visitor attitudes and intentions towards marine sustainability, specifically regarding overfishing and pollution? Second, does an information booklet handed out in addition to the visit have additional measurable impact? Aquarium visitors (n = 104) completed a questionnaire on marine sustainability attitudes and behavioral intentions before and after their visit. Half of the visitors also were given informational materials that offered behavioral solutions to the problem of overfishing. The aquarium visit significantly improved visitors’ overall attitudes and intentions. The information booklet additionally improved intentions significantly, but not attitudes. These findings show that a visit to an aquarium can help individuals develop what we term a marine mindset, a state of readiness to address marine sustainability issues. Implications, limitations, and ideas for further research are discussed.
