Evidence for a role of the responding agent in the joint compatibility effect

The present study explored the role of the responding agent in a social context. To do so, we developed a compatibility task with socially relevant but task-irrelevant stimuli (own face, neutral face, and a friend's face). Participants were required to perform naming responses to coloured diamonds, while the faces were presented as irrelevant stimuli. We observed faster responses in face–name compatible than in incompatible conditions. When the task was distributed among two friends, we observed a compatibility effect in a joint go/no-go condition, in which both participants performed their go/no-go tasks together. In contrast, no compatibility effect was obtained in an individual go/no-go condition. Further, the experiment showed that this joint compatibility effect was based on the compatibility between the irrelevant face and the responding agent. This result demonstrates that features of the responding agent play a crucial role in the joint compatibility effect.     

The effect of labour on ownership decisions in two cultures: Developmental evidence from Japan and the United Kingdom

Creative labour has an effect on children's and adults' ownership decisions in Western cultures. We investigated whether preschoolers and adults from an Eastern culture (Japan) would show a similar bias. In a first‐party task (Experiment 1), in which participants created their own objects, Japanese preschoolers but not adults assigned ownership to creators. When participants watched videos of third‐party conflicts between owners of materials and creators (Experiment 2), Japanese adults, but not preschoolers, transferred ownership to creators. In a British comparison group, both preschoolers and adults showed an effect of creative labour in the third‐party task. A bias to attribute ownership on the basis of creative labour is thus not specific to Western culture.     

Downward Social Comparison in the Minimal Intergroup Situation: A Test of a Self-Enhancement Interpretation1

We tested some implications of Wills' (1981) downward comparison interpretation of ingroup bias in the minimal intergroup paradigm. Based on a self-enhancement interpretation of ingroup bias, we predicted that subjects who expected to succeed on a task for dispositional reasons and subsequently failed would be most threatened by the feedback and hence, would engage in downward social comparison strategies. The results did not support the self-enhancement interpretation, but a number of interesting findings emerged. First, downward social comparison involving favorable comparisons of the ingroup relative to the outgroup was pervasive and not mediated by self-esteem. Second, ingroup bias was greatest when individuals' outcomes were consistent with their expectations; ingroup bias was mitigated when subjects received feedback that was inconsistent with their expectations. Third, although low self-esteem subjects rated members of the outgroup more negatively than did high self-esteem subjects, high self-esteem subjects engaged in more downward social comparison by enhancing the self relative to both members of the outgroup and their own ingroup. Finally, self-enhancement strategies were affected by performance expectations, attributions, and chronic self-esteem: People who expected to perform well because of stable, dispositional reasons and who were high in self-esteem showed the greatest tendency to engage in self-enhancing comparisons with others. This was true regardless of whether subjects ultimately succeeded or failed on the important task and regardless of whether the comparison others were members of the outgroup or the ingroup.     

The distinctiveness effect in forenames: The role of subjective experiences and recognition memory

We describe two experiments that tested the prediction that distinctive forenames would be better recognized than typical forenames and which investigated whether this distinctiveness effect, if obtained, occurred in subjective experiences of the recollective or familiarity components of recognition memory. To that end, the remember‐know paradigm was used to measure people's experiences of recollection or familiarity. The results revealed that distinctive forenames were more memorable than typical forenames and that that this distinctiveness effect was present only in the subjective experience of remembering. Additionally, the present research showed that these distinctiveness effects were present after retention intervals of both 1 and 7 days. These results replicate and extend past research on distinctiveness effects and also provide support for Rajaram's (1996) distinctiveness‐fluency account of the 2 states of subjective awareness.     

Valence, comparison focus and self-positivity biases: does it matter whether people judge positive or negative traits?

The present research questions whether mere valence affects self-other comparisons in the domain of trait characteristics. While some previous studies have reported greater positivity bias for the self when traits were positive than when traits were negative, we suggest that this is an ambiguous finding, because valence and content were confounded. When we unconfounded content and valence, valence had no effect on the magnitude of self-positivity bias displayed. We also replicate several findings for our unconfounded set of traits. Firstly, comparing others to the self, rather than comparing the self to others, lowered self-positivity for positive and negative traits (focus effect). Secondly, extremely positive and negative traits triggered greater positivity bias than did more moderately evaluated ones. Finally, we suggest that comparative self-positivity biases may be based on a general positivity bias.     

Recollection reduces unitised familiarity effect

Two types of encoding tasks have been employed in previous research to investigate the beneficial effect of unitisation on familiarity-based associative recognition (unitised familiarity effect), namely the compound task and the interactive imagery task. Here we show how these two tasks could differentially engage subsequent recollection-based associative recognition and consequently lead to the turn-on or turn-off of the unitised familiarity effect. In the compound task, participants studied unrelated word pairs as newly learned compounds. In the interactive imagery task, participants studied the same word pairs as interactive images. An associative recognition task was used in combination with the Remember/Know procedure to measure recollection-based and familiarity-based associative recognition. The results showed that the unitised familiarity effect was present in the compound task but was absent in the interactive imagery task. A comparison of the compound and the interactive imagery task revealed a dramatic increase in recollection-based associative recognition for the interactive imagery task. These results suggest that unitisation could benefit familiarity-based associative recognition; however, this effect will be eliminated when the memory trace formed is easily accessed by strong recollection without the need for a familiarity assessment.     

Does a person selectively recall the good or the bad from their personal past? It depends on the recall target and the person’s favourability of self-views

In three studies, participants remembered real-life behaviours at Time 1 and attempted to recall them at Time 2. When the recall target was the self, a positivity bias emerged: self-positivity. In Study 3, self-positivity extended to an individual (target) who was liked by the participant, but did it not extend to a disliked target. For this latter target, a negativity bias emerged. For recall targets that were participants’ acquaintances, self-positivity in recall was also eliminated in Studies 1 and 3, and a negativity bias in recall emerged in Study 2. Finally, in Study 2 (but not Study 3), the favourability of participants’ self-view predicted the magnitude of the self-positivity in self-recall, but it did not predict valence effects in other-recall. Taken together, the results indicate that the link between behaviour valence and recall is moderated by the recall target and the favourability of one’s self-view.

Self-enhancement and theory-based correction processes

Two studies examined bias correction by manipulating a perceived chronic judgmental bias (i.e., overestimator/underestimator) using a modified dot estimation task. In Experiment 1, participants corrected for this perceived estimation bias by making adjustments away from the arbitrary feedback about their personal bias tendencies. In Experiment 2, the perceived desirability of the same estimation bias was manipulated. Results indicated that self-enhancement concerns impacted perceivers’ motivation to correct, at a cost to accuracy. These studies expand our current understanding of theory-based correction by including self-enhancement motives as causes of correction, demonstrating that such corrections can decrease rather than increase judgment accuracy, and illustrating the usefulness of a new perceived bias manipulation in theory testing.     

Familiarity breeds attraction: effects of exposure on the attractiveness of typical and distinctive faces

Several studies have shown that facial attractiveness is positively correlated with both familiarity and typicality. Here we manipulated the familiarity of typical and distinctive faces to measure the effect on attractiveness. In our first experiment, we collected ratings of attractiveness, distinctiveness, and familiarity using three different groups of participants. Our stimuli included 84 images of female faces, presented in a full-face view. We replicated the finding that attractiveness ratings negatively correlate with distinctiveness ratings. In addition, we showed that attractiveness ratings were positively correlated with familiarity ratings. In our second experiment, we demonstrated that increasing exposure to faces increases their attractiveness, although there was no differential effect of exposure on typical and distinctive faces. Our results suggest that episodic familiarity affects attractiveness ratings independently of general or structural familiarity. The implications of our findings for the 'face-space' model are discussed.     

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.     

Perceived locus of control and satisfaction in same–sex friendships

Two studies examined perceptions of locus of control (LofC) and friendship satisfaction. Study 1 tested the accuracy of college students’ perceptions of a friend's LofC and their friendship satisfaction. Participants perceived their friends to be similar to themselves on LofC and satisfaction but these perceptions did not match the friends’ self–ratings. Instead, the perceptions reflected a belief in the similarity to the self—the Attraction–Similarity Hypothesis. Study 2 tested whether own and perceived friend's LofC predicted own satisfaction. The Internality Hypothesis indicates that an external LofC would predict dissatisfaction but an internal LofC would predict satisfaction. It was also predicted that these effects would be stronger for women's friendships than for men's friendships. For female, but not male, friendships, perceptions of the friend's external LofC predicted dissatisfaction.     

Are your cross‐ethnic friends ethnic and/or national group identifiers? The role of own and perceived cross‐ethnic friend's identities on outgroup attitudes and multiculturalism

We investigated how own ethnic and national identities and perceived ethnic and national identities of close cross‐ethnic friends may predict outgroup attitudes and multiculturalism among Turkish (majority status, N = 197) and Kurdish (minority status, N = 80) ethnic group members in Turkey (M_age = 21.12, SD = 2.59, 69.7% females, 30.3% males). Compared with Turkish participants, Kurdish participants were more asymmetrical in rating their cross‐ethnic friend's identities relative to their own, reporting higher ethnic identity, but lower national identity for themselves. Own ethnic identity was negatively associated with attitudes and multiculturalism, whereas own national identity was positively associated with only attitudes. Perceived cross‐ethnic friend's national identity was positively related to both outgroup attitudes and multiculturalism. Shared national identification (high levels of own and friend's national identity) led to most positive outgroup attitudes and highest support for multiculturalism. Findings were discussed in the light of social identity and common ingroup identity models.     

An event-related potential study of the revelation effect

Event-related potentials (ERPs) were recorded during a verbal recognition memory task in order to investigate whether changes in familiarity are part of the explanation for the revelation effect. For half of the test words, participants solved an anagram prior to making the old/new recognition judgment. A revelation effect was obtained: When test words were preceded by the anagram task, a higher probability of an old response was associated with the items than was otherwise the case. The ERPs recorded time-locked to the onset of the test words were separated according to old/new status andthe presence/absence of the anagram task. The ERP index of familiarity was of lower amplitude for both old and new items that were preceded by the anagram task. These findings are consistent with the view that part of the explanation for the revelation effect is a reduction in the familiarity of the critical test items.     

The effect of familiarity on within-person age judgements from voices

Listeners can perceive a person’s age from their voice with above chance accuracy. Studies have usually established this by asking listeners to directly estimate the age of unfamiliar voices. The recordings used mostly include cross-sectional samples of voices, including people of different ages to cover the age range of interest. Such cross-sectional samples likely include not only cues to age in the sound of the voice but also socio-phonetic cues, encoded in how a person speaks. How age perpcetion accuracy is affected when minimizing socio-phonetic cues by sampling the same voice at different time points remains largely unknown. Similarly, with the voices in age perception studies being usually unfamiliar to listeners, it is unclear how familiarity with a voice affects age perception. We asked listeners who were either familiar or unfamiliar with a set of four voices to complete an age discrimination task: listeners heard two recordings of the same person’s voice, recorded 15 years apart, and were asked to indicate in which recording the person was younger. Accuracy for both familiar and unfamiliar listeners was above chance. While familiarity advantages were apparent, accuracy was not particularly high: familiar and unfamiliar listeners were correct for 68.2% and 62.7% of trials, respectively (chance = 50%). Familiarity furthermore interacted with the voices included. Overall, our findings indicate that age perception from voices is not a trivial task at all times – even when listeners are familiar with a voice. We discuss our findings in the light of how reliable voice may be as a signal for age.     

Motivated to confront: How experiencing anger affects anchoring bias

Prior research has asserted that emotions affect anchoring bias in decision making through the emotion's certainty appraisal or through the emotion's action tendencies, but these prior studies investigate the role of each component—appraisal or action tendency—without accounting for potential effects of the other one. The current research investigates whether anger exerts a significant effect on anchoring bias by activating a desire to confront a potential anchor. Importantly, the studies compare the effect of anger versus disgust, emotions that differ in their action tendency but are similar in their certainty appraisal. In Study 1, participants completed an emotion induction task and then a negotiation task where the first offer from the negotiation partner served as a potential anchor. Anger led to more deviation from the anchor compared with disgust or neutral feelings. Subsequent studies provide evidence that the angry participants are less anchored when the anchor value comes from a more confrontable source (someone else vs. themselves in Study 2 and an out‐group member vs. an in‐group member in Study 3).     

Preadolescents' recognition of faces of unfamiliar peers: the effect of attractiveness of faces

The authors examined preadolescents' ability to recognize faces of unfamiliar peers according to their attractiveness. They hypothesized that highly attractive faces would be less accurately recognized than moderately attractive faces because the former are more typical. In Experiment 1, 106 participants (M age = 10 years) were asked to recognize faces of unknown peers who varied in gender and attractiveness (high- vs. medium-attractiveness). Results showed that attractiveness enhanced the accuracy of recognition for boys' faces and impaired recognition of girls' faces. The same interaction was found in Experiment 2, in which 92 participants (M age = 12 years) were tested for their recognition of another set of faces of unfamiliar peers. The authors conducted Experiment 3 to examine whether the reason for that interaction is that high- and medium-attractive girls' faces differ more in typicality than do boys' faces. The effect size of attractiveness on typicality was similar for boys' and girls' faces. The overall results are discussed with reference to the development of face encoding and biological gender differences with respect to the typicality of faces during preadolescence.     

Social Comparison of Health Risks: Locus of Control,the Person-Positivity Bias,and Unrealistic Optimism1

People typically attribute lower health risks to themselves than to others, a phenomenon referred to as unrealistic optimism. The present study tested the person positivity bias as a previously unexamined explanation of the phenomenon and analyzed the relationship between unrealistic optimism and expectations of control. High-school students estimated their own and one of three other persons’(the average student's, a randomly chosen student's, or their best same-sex friend's) chances of getting health problems. They also filled out questionnaires measuring locus of control and health-protective behavior. In contrast with the person positivity explanation, unrealistic optimism was not restricted to the “average other” condition. However, unrealistic optimism was stronger in subjects with a more internal locus of control than in subjects with a rather external locus of control. An unpredicted effect of estimation order was observed: Unrealistic optimism was stronger in subjects who estimated the comparison person's risks first than in subjects who started with own risks. This effect can be understood in terms of Codol's observation that people perceive others as more similar to themselves than they themselves are to others.
