Preferring the One in the Middle: Further Evidence for the Centre‐stage Effect

The location of an item influences a person's preference for that item, but it is unclear whether there is a preference for items located on the right or in the centre. In replication of the centre‐stage effect, it was found that when participants were presented with a line of five pictures, they preferred pictures in the centre rather than at either end. This applies when the line of pictures was arranged horizontally or vertically and when participants selected from five pairs of identical socks arranged vertically. The results support the centre‐stage explanation of location‐based preference rather than the hemispheric difference or body‐specific accounts. Implications of the effects of location on consumer choices and preference decisions are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

Do optimism and pessimism have different relationships with personality dimensions? A re-examination

The classic, well-cited study by Marshall et al. (1992) demonstrated that optimism correlates stronger with extraversion than does pessimism and pessimism correlates stronger with neuroticism than does optimism, and these results lent support to their claim that optimism and pessimism are two separate constructs. However, we argued that their results are likely the outcome of scale artefact caused by item valence (or item favorability). In an empirical study (N = 1016), we evaluated the correlation of optimism scores and pessimism scores with the most common measure of optimism - Life Orientation Test-Revised (LOT-R). As expected, when item valence effect was not controlled, we replicated the finding by Marshall et al. (1992) that optimism and pessimism show differential correlations with extraversion and neuroticism. After item valence was controlled such pattern of relationships was greatly reduced. Suggestions for future research to resolve the dimensionality debate for optimism-pessimism are discussed.     

Distinct brain systems underlie the processing of valence and arousal of affective pictures

Valence and arousal are thought to be the primary dimensions of human emotion. However, the degree to which valence and arousal interact in determining brain responses to emotional pictures is still elusive. This functional MRI study aimed to delineate neural systems responding to valence and arousal, and their interaction. We measured neural activation in healthy females (N = 23) to affective pictures using a 2 (Valence) × 2 (Arousal) design. Results show that arousal was preferentially processed by middle temporal gyrus, hippocampus and ventrolateral prefrontal cortex. Regions responding to negative valence included visual and lateral prefrontal regions, positive valence activated middle temporal and orbitofrontal areas. Importantly, distinct arousal-by-valence interactions were present in anterior insula (negative pictures), and in occipital cortex, parahippocampal gyrus and posterior cingulate (positive pictures). These data demonstrate that the brain not only differentiates between valence and arousal but also responds to specific combinations of these two, thereby highlighting the sophisticated nature of emotion processing in (female) human subjects.     

The Fluency Amplification Model: Fluent stimuli show more intense but not evidently more positive evaluations

Processing fluency plays a large role in forming judgments, as research repeatedly shows. According to the Hedonic Fluency Model, more fluently processed stimuli are rated more affectively positive than less fluently processed stimuli. Most research documenting such findings uses neutral or positive stimuli with low complexity, thus any potential impact of initial stimulus valence cannot be tested. In the present study, 60 IAPS stimuli ranging from very negative to very positive valence were rated on liking by participants. Processing fluency was manipulated through perceptual priming (7 ms). Results of Experiment 1 (N = 35) support the prediction of the Hedonic Fluency Model, but only for stimuli with an initially positive valence. However, when negative stimuli were processed more fluently, they were rated as more negative than when processed less fluently. Experiment 2 (N = 39) showed that enhancing the accessibility of the stimulus content (via prolonging the prime duration to 100 ms) cannot account for the results of Experiment 1, since Experiment 2 failed to replicate the findings obtained in Experiment 1. Potential factors influencing affective evaluation of negative stimuli are discussed. A model is offered for the reinterpretation of processing fluency as an amplifying factor for evaluative judgment.     

Stimulus exposure and gaze bias: A further test of the gaze cascade model

We tested predictions derived from the gaze cascade model of preference decision making (Shimojo, Simion, Shimojo, & Scheier, 2003; Simion & Shimojo, 2006, 2007). In each trial, participants’ eye movements were monitored while they performed an eight-alternative decision task in which four of the items in the array were preexposed prior to the trial. Replicating previous findings, we found a gaze bias toward the chosen item prior to the response. However, contrary to the prediction of the gaze cascade model, preexposure of stimuli decreased, rather than increased, the magnitude of the gaze bias in preference decisions. Furthermore, unlike the prediction of the model, preexposure did not affect the likelihood of an item being chosen, and the pattern of looking behavior in preference decisions and on a nonpreference control task was remarkably similar. Implications of the present findings in multistage models of decision making are discussed.     

Tracking the Decision‐Making Process in Multiple‐Choice Assessment: Evidence from Eye Movements

This study investigated students' decision‐making processes in a knowledge‐assessing multiple‐choice (MC) test using eye‐tracking methodology. More precisely, the gaze bias effect (more attention to more preferred options) and its relation to domain knowledge were the focus of the study. Eye movements of students with high (HPK) and low (LPK) prior domain knowledge were recorded while they solved 21 MC items. Afterwards, students rated every answer option according to their subjective preference. As expected, both HPK and LPK students showed a gaze bias towards subjectively preferred answer options, whereby HPK students spent more time on objectively correct answers. Furthermore, a fine‐grained time‐course analysis showed similar patterns of attention distribution over time for both HPK and LPK students, when focusing on subjective preference levels. Thus, these data offer a new perspective on knowledge‐related MC item solving and provide evidence for the generalizability of the gaze bias effect across decision tasks.

Facial asymmetry detection in patients with body dysmorphic disorder

Cognitive-behavioral models of body dysmorphic disorder (BDD) propose that individuals with BDD may possess a better or more developed sense of aestheticality than do individuals without BDD. Evidence for this proposition, however, is limited. One perceptual process that could contribute to heightened aestheticality is the ability to detect differences in symmetry. In this experiment we tested whether individuals with BDD (n = 20), relative to individuals with obsessive compulsive disorder (OCD; n = 20) and healthy controls (n = 20), show an enhanced ability to detect differences in the symmetry of others’ faces, symmetry of dot arrays, and/or show a greater preference for symmetrical faces. Individuals with BDD were not significantly more accurate in detecting differences in facial symmetry or dot arrays relative to individuals with OCD and healthy controls. Individuals with OCD took longer to make facial symmetry judgments than did individuals in the other two groups. All participants, regardless of diagnostic group, preferred more symmetrical faces than nonsymmetrical ones. Taken together, our results do not support a heightened perceptual ability or evaluative preference for symmetry among individuals with BDD.     

What's up? Emotion-specific activation of vertical space during language processing

The relationship between language processing and vertical space has been shown for various groups of words including valence words, implicit location words, and words referring to religious concepts. However, it remains unclear whether these are single phenomena or whether there is an underlying common mechanism. Here, we show that the evaluation of word valence interacts with motor responses in the vertical dimension, with positive (negative) evaluations facilitating upward (downward) responses. When valence evaluation was not required, implicit location words (e.g., bird, shoe) influenced motor responses whereas valence words (e.g., kiss, hate) did not. Importantly, a subset of specific emotional valence words that are commonly associated with particular bodily postures (e.g., proud → upright; sad → slouched) did automatically influence motor responses. Together, this suggests that while the vertical spatial dimension is not directly activated by word valence, it is activated when processing words referring to emotional states with stereotypical bodily-postures. These results provide strong evidence that the activation of spatial associations during language processing is experience-specific in nature and cannot be explained with reference to a general mapping between all valence words and space (i.e., all positive and negative words generally relate to spatial processing). These findings support the experiential view of language comprehension, suggesting that the automatic reactivation of bodily experiences is limited to word groups referring to emotions or entities directly associated with spatial experiences (e.g., posture or location in the world).     

Dads or cads? Women’s strategic decisions in the mating game

We report the findings of two studies (N = 142; N = 28) investigating women’s preference for men in short- and long-term mating scenarios and perceptions of honesty of dating adverts written by men high or low in Machiavellianism. Overall, men low on Machiavellianism (viz., dads), were preferred as long-term mates; and men high on Machiavellianism (viz., cads) as short-term mates. Fertile women preferred cads for a short-term relationship and dads as a long-term partner. Higher ratings were given to all adverts when females were fertile, suggesting generally higher levels of desire for a partner when the possibility of conception is highest. In contrast to previous work suggesting traits like Machiavellianism may facilitate a deceptive or exploitative mating strategy in men, the present results suggest (1) women are attuned to differences in men’s personality as a function of fertility and (2) affirms that women prefer cads for short-term mating and dads for long-term mating.     

Empathy towards individuals of the same and different ethnicity when depicted in negative and positive contexts

Individuals can show different empathy responses towards others depending on in-group and out-group biases. The present research tested empathy biases related to ethnicity when targets were depicted in negative and positive contexts. Caucasian (n = 99) and Asian (n = 99) participants gave subjective ratings for images depicting same or other ethnicity individuals in socially-relevant negative and positive contexts. Participants rated significantly higher on all three dimensions of empathy (affect, perspective taking, and understanding) for same ethnicity targets than for other ethnicity targets. However, this bias was found only for targets depicted in negative contexts. Moreover, no ethnicity bias was found for ratings of valence, arousal, distress, and interest. The results suggest that ethnicity-related biases in empathy are present, are limited to negative contexts, and are not merely a manifestation of a more general cognitive or affective bias.     

Core self-evaluation moderates distinctive similarity preference in ideal partner’s personality

This research investigated the moderation effects of core self-evaluation (CSE) on singles’ ideal partner preference, concerning distinctive similarity in personality. The data were collected from singles from three countries (i.e., China, Denmark, and US), and modelled in a multilevel profile analysis. The results show that CSE moderated distinctive profile similarity preference in that people high in CSE preferred higher distinctive profile similarity with their ideal partner. In addition, CSE moderated distinctive trait similarity preference in Emotionality, Extraversion, Agreeableness, and Conscientiousness in that people high in CSE preferred their ideal partner to share higher distinctive similarity on these four traits. Implications and limitations of the research and findings are also discussed.     

Essentialism and compassion: Predicting preference for noun labels applied to people with mental disorders

Two studies, one correlational and one experimental, examined preference for noun labels applied to people with mental disorders (e.g., John is a schizophrenic) as a function of differences in essentialist thinking and compassion. Study 1 (N = 360) showed that those high in essentialist thinking were more likely than those low in essentialist thinking to endorse noun labels. Study 2 (N = 86) showed that those led to experience state compassion were less likely to endorse noun labels than those in a control condition. This research is discussed with respect to processes underlying these effects, the positive psychology of language, limitations and future research directions, and implications for reducing stigmatizing attitudes towards those with mental disorders.     

Should you Sleep on it? The Effects of Overnight Sleep on Subjective Preference‐based Choice

Conventional wisdom and studies of unconscious processing suggest that sleeping on a choice may improve decision making. Although sleep has been shown to benefit several cognitive tasks, including problem solving, its impact on everyday choices remains unclear. Here we explore the effects of ‘sleeping on it’ on preference‐based decisions among multiple options. In two studies, individuals viewed several attributes describing a set of items and were asked to select their preferred item after a 12‐hour interval that either contained sleep or was spent fully awake. After an overnight period including sleep, individuals showed increases in positive perceptions of the choice set. This finding contrasts with previous research showing that sleep selectively enhances recall for negative information. In addition, this increase in positive recall did not translate into a greater desire to purchase their preferred item or into an overall benefit for choice satisfaction. Time‐of‐day controls were used to confirm that the observed effects could not be explained by circadian influences. Thus, we show that people may feel more positive about the choice options but not more confident about the choice after ‘sleeping on’ a subjective decision. We discuss how the valence of recalled choice set information may be important in understanding the effects of sleep on multi‐attribute decision making and suggest several avenues for future research.

Personality correlates of party preference: The Big Five in five big European countries

The Big Five Model was used to assess the role of personality traits in orienting voting choice across five European countries (n = 1288). Findings from Italy, Spain, Germany, Greece, and Poland showed that the Big Five were linked to party preference in theoretically consistent ways. Traits had substantial effects on voting, whereas the socio-demographic characteristics of gender, age, income, and educational level had weaker influences. In each country, voters’ traits are seemingly congruent with the policies of their preferred party. The Openness trait has been shown to be the most generalizable predictor of party preference across the examined cultures. Conscientiousness was also a valid predictor, although its effect was less robust and replicable. Similarities and differences across countries were discussed and linked to the nature of the respective political discourses.     

The influence of neuroticism on spatial presence and enjoyment in films

The purpose of the present study was to clarify the influence of neuroticism on the sensation of spatial presence and enjoyment in films. We presented participants (N = 64) a fearful, sad, and funny movie sequence. Across all media, individuals scoring high on neuroticism experienced more presence than those scoring low. In contrast, no main effect was found on enjoyment. In terms of enjoyment, however, neuroticism interacted with the valence of the sequences: in the two conditions with negative valence (fearful and sad sequence), participants scoring high on neuroticism reported less enjoyment than those scoring low on neuroticism. Opposite results were observed in the funny sequence: participants scoring high on neuroticism enjoyed the funny sequence more than those scoring low on neuroticism. Thus, neuroticism increased presence within all conditions, whereas individuals scoring high on neuroticism only experienced increased enjoyment in positive media contents.     

Strength of Preference and Effects of Valence in the Domains of Gains and Losses

In comparative judgments that follow binary choices, judgments of “How much better is a preferred option?” and “How much worse is a less preferred option?” may differ in their magnitudes (“valence effects”). This paper analyzed cognitive processes that underlie positive valence effects (“Better” exceeding “Worse”) and negative valence effects (Worse exceeding Better). My analyses used a “focus shift model.” The focus shift model postulates that choice options are represented as sets of desirable and undesirable features. Difference judgments are reached by assigning subjective weights onto such features and integrating weighted feature contributions. Positive and negative valence effects reflect the differences in subjective weighting depending on valence of judgments. Experiments 1 through 3 showed that systematic positive valence effects were observed in the domain of gains, whereas negative valence effects were observed in the domain of losses. Estimates of subjective weights showed that valence effects occurred when participants heavily weighted desirable features in preferred options and undesirable features in less preferred options. These patterns of subjective weighting for positive and negative valence effects were consistent with the focus shift model. Data were more consistent with the focus shift model over alternative explanations of valence effects. Relationship with relevant economic and psychological phenomena are discussed.     

Intergroup Discrimination Involving Negative Outcomes and Self‐Esteem

Two studies examined the link between intergroup discrimination involving negative outcomes (i.e., removal of positive resources and allocation of noxious resources), global self‐esteem (GSE), and collective self‐esteem (CSE). Study 1 found that New Zealanders who took away more positive resources from out‐group than in‐group members experienced enhanced CSE, but not GSE. These findings were replicated in Study 2, with respect to the allocation of noxious resources (i.e., white noise). New Zealanders' GSE and CSE assessed prior to the allocation of noxious resources were unrelated to the subsequent allocation of white noise. The data are interpreted to indicate that intergroup discrimination involving negative outcomes leads to enhanced CSE. However, neither GSE nor CSE predict such discrimination.     

The central tendency of a social group can affect ratings of its intragroup variability in the absence of social identity concerns

People report less variability within in-groups than within out-groups when they make their ratings on traits on which the in-group has a higher central tendency than the out-group. [Simon, 1992a] and [Simon, 1992b] proposed that this effect is motivated by the need to protect a positive social identity. The present research tested the necessity of the social identity motive by using participants who were not members of any of the target groups that they judged. In Study 1 (N = 60), psychology undergraduate students reported significantly less intragroup variability on positive traits among a group of fashion designers that won a fashion competition than among a group that lost. Study 2 (N = 75) found a reverse effect on negative traits and confirmed the mediating role of perceived central tendency. These results demonstrate that the social identity motive is not necessary to explain the effect of central tendency on ratings of intragroup variability, and that the effect is more general than previously reported.     

The consistency and structure of aspect-based career preferences

Career aspects (e.g., work environment, using verbal ability, length of training, teamwork) are an elaboration and extension of vocational interests. Aspect-based preferences can serve individuals and their career counselors only if they are reliable and stable. Study 1 estimated the two-week test–retest reliability of 213 college freshmen's preferences in 31 career aspects and the two-year stability of these preferences for 132 of these freshmen. The two-week reliability and the two-year stability of both the within-aspect preferred levels (e.g., “only indoors” most preferred, but “mostly indoors” is also acceptable) and the aspect importance were tested for each of the aspects. The interquartile ranges of the two-week reliability of the aspect importance and of the preferred within-aspect levels were .54–.62 and .63–.74 for the 31 aspects; the interquartile ranges of the two-year stabilities were .38–.48 and .48–.59, respectively. These interquartile ranges reflect the variance in consistency among the aspects. Study 2 explored the structure of the aspects based on the pattern of associations among them. In addition, it examined the consistency of the aspect structures by comparing them in four samples (total N = 40,313). The structure was found consistent across time (Spearman r_s = .88, .76 and .68, two weeks, two years, and 20 years later, respectively), within culture (r_s = .75 and .76, for women and men, respectively), and across cultures (USA and Israel; r_s = .64). Theoretical and practical implications are discussed.     

On the stability and relevance of the exercise heart rate–music-tempo preference relationship

ObjectivesTo examine the stability of the cubic (two points of inflection) exercise heart rate–music-tempo preference relationship found by Karageorghis et al. (2011) in cycle ergometry using a different exercise modality (treadmill exercise). To advance previous related studies through the inclusion of psychological outcome variables (e.g., state attention and intrinsic motivation) and post-experiment interviews.DesignA mixed-model experimental design was employed with two within-subject factors (exercise intensity and music tempo) and a between-subjects factor (gender). The experiment was supplemented by qualitative data that were analyzed using inductive content analysis.MethodsParticipants (n = 22) exercised at six intensities (40–90% maxHRR) during which they were exposed to music tracks at four tempi and a no-music control. Music preference, affective valence, and perceived activation were assessed during the task. Immediately afterwards, an attentional focus item, the short Flow State Scale-2 and items from the Intrinsic Motivation Inventory were administered. A subsample of participants (n = 8) was interviewed using a schedule of open-ended questions.ResultsResults did not support a cubic relationship but rather a quadratic one (one point of inflection), and there was a weak association between the optimal choice of music tempo and positive psychological outcomes.ConclusionsThe range of preferred tempi for treadmill exercise (123–131 bpm) was narrower than that for cycle ergometry (125–140 bpm). Regardless of its tempo, music reduced the number of associative thoughts by ∼10% across all exercise intensities.
