Standing up for a change: reducing bias through interpersonal confrontation

Three experiments examined the effectiveness of interpersonal confrontations as a means for decreasing stereotypic responding. After making stereotypic inferences about Black individuals, participants were confronted and reactions were measured across various intrapersonal and interpersonal response domains. Confrontations varied in level of hostility (Experiment 1) and whether they were expressed by a Black or White person (Experiment 2). Results indicate that although confrontations (and particularly hostile ones) elicited negative emotions and evaluations toward the confronter, participants also experienced negative self-directed affect. Furthermore, regardless of who did the confronting or how much hostility was expressed, confronted participants subsequently were less likely to provide stereotypic responses (Experiments 1-2), and the effect of the confrontation generalized to reporting less prejudiced attitudes (Experiment 3).     

Planning to reach for an object changes how the reacher perceives it

Three experiments assessed the influence of the Ebbinghaus illusion on size judgments that preceded verbal, grasp, or touch responses. Prior studies have found reduced effects of the illusion for the grip-scaling component of grasping, and these findings are commonly interpreted as evidence that different visual systems are employed for perceptual judgment and visually guided action. In the current experiments, the magnitude of the illusion was reduced by comparable amounts for grasping and for judgments that preceded grasping (Experiment 1). A similar effect was obtained prior to reaching to touch the targets (Experiment 2). The effect on verbal responses was apparent even when participants were simply instructed that a target touch task would follow the verbal task. After participants had completed a grasping task, the reduction in the magnitude of the illusion remained for a subsequent verbal-response judgment task (Experiment 3). Overall, the studies demonstrate strong connections between action planning and perception.     

Genuineness matters: Using cheaper, generic products induces detrimental self-evaluations

People purchase generic products in an attempt to reduce costs. In this article, we showed that using generic products primes a devalued sense of self-worth manifested by increasing the likelihood of lower self-evaluations. In Experiment 1, participants were randomly assigned to use generic or genuine computer peripherals to make personal vitas for an upcoming recruitment orientation. Those using generic peripherals expected to earn a lower salary per month than the participants using original peripherals. Experiment 2 showed that the effect of using generic accessories extended to the context of interpersonal relations, influencing how participants thought others judged them in a get-acquainted task. Experiment 2 further demonstrated that the feelings of devalued self-worth primed by using compatible mobile-phone batteries mediated the effect of generic products on self-estimated attractiveness. Together these findings suggested that, even incidentally used cheaper, generic products may prime people for a lowered sense of self-worth, which would then produce disadvantageous self-evaluations.     

Grasping remaps the distribution of visuospatial attention and enhances competing action activation

We examined how action goals influence the distribution of visuospatial attention near the body (Experiment 1) and how the temporal relationship between distractors and targets modifies shifts in visuospatial attention (Experiment 2). Targets were light emitting diodes (LEDs) in the left and right hemispace of a visual display. Following left or right target illumination, participants reached to point-to or grasp target object in blocked trials. Coincident with target onset, a distractor LED illuminated in the same or opposite hemispace between the initiation point and target, or no distractor appeared. In Experiment 1, during grasping there was a larger temporal interference effect (slower reach initiation) than with pointing. When grasping versus pointing, participants deviated more towards same-side distractors and away from opposite-side distractors. In Experiment 2, distractors onset 200ms prior to (?200-ms), coincident with (0 ms), or 200ms following (+200 ms) the target. For both reach types, ?200-ms distractors had greater onset temporal interference than 0 ms and +200-ms distractors. For grasping, +200 ms distractors had larger temporal interference than 0 ms distractors. For ?200-ms, reach trajectories deviated more towards opposite-side distractors and away from same-side distractors, the reverse of the pattern for 0 ms and +200-ms distractors.

Effects of processing style on responsiveness to affective stimuli and processing fluency

In the present study, we provide direct evidence for effects of global versus local processing on responsiveness to and reliance on affective information in judgement and decision-making. Results of Experiments 1 and 2 showed an increased responsiveness to affective stimuli among participants in a global processing mode. Experiment 3 showed similar effects for processing fluency; participants adopting a global processing style showed an increased reliance on fluency. Experiment 4 replicated our findings in a more mundane judgement task in which participants judged apartments. We discuss our findings in relation to the distinction between intuitive versus deliberative modes of thinking.     

Early learning differences between intra- and interpersonal interlimb coordination

Intrinsic coordination patterns exist between limbs such that 1) coordination at these states is inherently stable, 2) any other pattern requires learning to produce, and 3) this learning is subject to interference from a systemic bias towards intrinsic patterns. The dynamics that govern intrapersonal interlimb coordination also govern interpersonal coordination. However, intrapersonal coordination exhibits greater coupling strength and thus more stable intrinsic dynamics than interpersonal coordination. Because the strength of intrinsic coordination tendencies has consequences for learning coordination patterns, the differences in coupling strength between intra- and interpersonal coordination should impact the ability to perform new coordination patterns via greater or less interference from intrinsic dynamics. This was investigated by measuring participants’ performance as they learned a new coordination pattern alone (intrapersonal) or in pairs (interpersonal). Participants were implicitly tasked with learning the pattern as they separately controlled the vertical and horizontal position of an on-screen cursor to trace a circling target. We observed better performance of dyads on first trial and steeper learning trajectories for individuals. Overall, these results indicate that individuals experienced greater interference from stronger intrinsic coordination dynamics during early learning but could overcome this interference and achieve similar performance to that of dyads with very little practice.     

Cognitions and behaviour in a hierarchy: Mulder's power theory revisited

In this study, Mulder's power theory consisting of the power distance reduction tendency (PDR) of less powerful group members towards more powerful others, and the power distance enlargement tendency (PDE) of more powerful group members towards less powerful others, is investigated. In particular, two different interpretations of the relationships Mulder hypothesized between power distance and power tendencies are examined. In Experiment 1 no support was found for the interpersonal interpretation. Evidence for the intrapersonal interpretation was found only for the PDE. The most remarkable difference between these results and the results of previous experiments was that we did not find any consistent support for an increased interpersonal PDR with smaller power distance. Therefore, in Experiment 2 a more extensive investigation was undertaken focusing on interpersonal measures similar to the one used earlier by Mulder and his co-workers. Results of these measures yielded support for the interpersonal interpretations of both tendencies. In the discussion an explanation for the obtained results is offered that departs from the (in) stability of the power hierarchy.     

Investigating the social behavioral dynamics and differentiation of skill in a martial arts technique

Coordinating interpersonal motor activity is crucial in martial arts, where managing spatiotemporal parameters is emphasized to produce effective techniques. Modeling arm movements in an Aikido technique as coupled oscillators, we investigated whether more-skilled participants would adapt to the perturbation of weighted arms in different and predictable ways compared to less-skilled participants. Thirty-four participants ranging from complete novice to veterans of more than twenty years were asked to perform an Aikido exercise with a repeated attack and response, resulting in a period of steady-state coordination, followed by a take down. We used mean relative phase and its variability to measure the steady-state dynamics of both the inter- and intrapersonal coordination. Our findings suggest that interpersonal coordination of less-skilled participants is disrupted in highly predictable ways based on oscillatory dynamics; however, more-skilled participants overcome these natural dynamics to maintain critical performance variables. Interestingly, the more-skilled participants exhibited more variability in their intrapersonal dynamics while meeting these interpersonal demands. This work lends insight to the development of skill in competitive social motor activities.     

Motor imagery may incorporate trial-to-trial error

The authors tested for 1/f noise in motor imagery (MI). Participants pointed and imagined pointing to a single target (Experiment 1), to targets of varied size (Experiment 2), and switched between pointing and grasping (Experiment 3). Experiment 1 showed comparable patterns of serial correlation in actual and imagined movement. Experiment 2 suggested increased correlation for MI and performance with increased task difficulty, perhaps reflecting adaptation to a more complex environment. Experiment 3 suggested a parallel decrease in correlation with task switching, perhaps reflecting discontinuity of mental set. Although present results do not conclusively reveal 1/f fluctuation, the emergent patterns suggest that MI could incorporate trial-to-trial error across a range of constraints.     

The effects of local and global processing demands on perception and action

The line-bisection task, adapted to utilise a wooden rod as the bisection stimulus, has revealed that patients with visuo-spatial neglect may be more accurate at bisection when asked to pick up the rod, compared to pointing to its centre. We recently reported that neurologically intact participants show a similar dissociation on this task-demonstrating a rightward bias when pointing to the centre, which was not present when grasping the rod by the centre. The current paper examined how pointing and grasping responses were affected by adapted rod-bisection tasks that emphasised local or global processing. In Experiment 1, 26 participants completed four rod-bisection tasks. The rods were compound stimuli and the participants directed to focus on either the local or global level. The results demonstrated that when participants focused on the global level, the previous dissociations found for pointing and grasping conditions were evident. However, the perception of centre did change when participants focused on the local level: both the pointing and grasping responses were rightward biased. In Experiment 2, 42 participants completed three bisection tasks which again emphasised either the local or global level, but in different sets of stimuli. The results of this task further support the findings in Experiment 1: the rightward bias in the local-bisection task was again evident and in addition, the global-bisection task resulted in no bias and no difference between the pointing and grasping bisections. These results demonstrate how task demands can similarly affect the pointing and grasping responses, and indicate that local and global processing may be involved in perception/action dissociations on rod bisection.     

Sex and culture differences in perceptions of estimated multiple intelligence for self and family: A Macanese1Portuguese comparison

Differences in sex and culture between Macanese and Portuguese university students in self and parental estimations of IQ were examined using Gardner's ( 1999 ) list of 10 multiple intelligences. A total of 197 Macanese (90 male and 107 female) and 331 Portuguese (139 male and 192 female) students participated in the investigation. The following hypotheses were tested: it was anticipated that there would be sex differences in self‐rated mathematical and spatial intelligence, with men giving higher self‐estimates than women; it was predicted that there would be cultural differences between Macanese and Portuguese, with the former awarding themselves and their parents significantly lower scores than the latter; participants would rate their fathers as more intelligent overall than their mothers; the best predictors of overall (g) IQ would be logical/mathematical, spatial, and verbal intelligence. In contrast to previous results (Furnham, 2001 ), when examined separately, gender differences in both self‐estimates and parents estimates did not occur in the Macanese sample. There were, however, consistent and clear culture differences. Portuguese gave higher self and family ratings than Macanese, as expected. Portuguese rated their verbal, body kinetic, interpersonal, intrapersonal, and naturalistic intelligence higher than did Macanese. Portuguese rated verbal, mathematical, spatial, interpersonal, intrapersonal, existential, and naturalistic father's intelligence higher than did Macanese. Portuguese rated verbal, mathematical, spatial, musical, interpersonal, intrapersonal, existential, spiritual, and naturalistic mother's intelligence higher than did Macanese. Participants of both cultures rated overall intelligence of their father higher than that of their mother. This was also to be expected as previous studies have shown this to be the case in terms of gender stereotyping. In both cultures verbal and interpersonal intelligences predict overall intelligence. However, in Macao, body‐kinetic and intrapersonal intelligences, and in Portugal logical and naturalistic intelligences, also predict overall intelligence. Implications of these results for education and self‐presentations are considered.     

Being responsible versus acting responsibly: Effects of agency and risk taking on responsibility judgments

In three experimental studies, with managers and students as participants, we explore in this paper the relation between two kinds of responsibility judgments, called Responsibility 1 (R1) and Responsibility 2 (R2). Decision makers can be viewed as being more or less responsible for their choice and its consequences (R1). Their actions can also be evaluated, from a normative point of view, as instances of more or less responsible behavior (R2). Experiment 1 showed that managers who depart from the default or “normal” course of action, by choosing a new (versus familiar) alternative, changing (versus sticking to) an initial decision, or going against (versus following) the advice of a management team, are rated as more responsible (R1) for the outcomes of their decision. At the same time, they are perceived to act in a less responsible way (R2). Experiment 2 compared decision makers choosing between more or less risky options. High risk takers were held more responsible (R1) for their choice and for its consequences, but were again viewed as behaving in a less responsible way (R2) than low risk takers. In Experiment 3, participants judged decision makers who followed or opposed others' advice by choosing either a high or a low risk option. Opposing others' advice led to higher R1 and lower R2 scores, especially when choosing the high risk option, moderated by outcome (successful decisions appearing more responsible than those that went wrong). Thus R1 and R2 judgments should be distinguished as having different and sometimes even opposite determinants.     

Visual estimation of spatial requirements for locomotion in novice wheelchair users

Locomotion using a wheelchair requires a wider space than does walking. Two experiments were conducted to test the ability of nonhandicapped adults to estimate the spatial requirements for wheelchair use. Participants judged from a distance whether doorlike apertures of various widths were passable or not passable. Experiment 1 showed that participants underestimated the spatial requirements for wheelchair use but overestimated the spatial requirements for walking. Experiment 2 showed that their underestimation improved but was not completely eliminated after 8 days of practice passing through apertures. Analyses of wheelchair performance in the practice condition showed that the underestimation may have arisen from misperception of the positions of the hands when the participants were grasping the wheelchair hand-rims. The theoretical and practical implications of these findings are discussed.     

Induced power changes the sense of agency

Power differentials are a ubiquitous feature of social interactions and power has been conceptualised as an interpersonal construct. Here we show that priming power changes the sense of agency, indexed by intentional binding. Specifically, participants wrote about episodes in which they had power over others, or in which others had power over them. After priming, participants completed an interval estimation task in which they judged the interval between a voluntary action and a visual effect. After low-power priming, participants judged intervals to be significantly longer than judgments after high-power or no priming. Thus, intentional binding was significantly changed by low-power, suggesting that power reduces the sense of agency for action outcomes. Our results demonstrate a clear intrapersonal effect of power. We suggest that intentional binding could be employed to assess agency in individuals suffering from anxiety and depression, both of which are characterised by reduced feelings of personal control.     

Grip width and the organization of force output

The authors investigated the structure of force production and variability as a function of grip configuration and width during precision grasping. Variability was studied in absolute (standard deviation) and relative (coefficient of variation) terms; in addition, the authors used approximate entropy to examine regularity. In Experiment 1, the participants (N = 14) used a 2-digit grasp (thumb, index), whereas in Experiment 2, the participants (N = 11) used a 3-digit grasp (thumb, index, middle). The level and regularity of force increased with grip width. The amount of variability was least at narrow grip widths for 2-digit grasping and greatest at narrow grip widths for 3-digit grasping. That pattern of findings is not necessitated by the mechanical equilibrium of grasping; thus, it also reflected adaptive neural reorganization of force output to task demands.     

Testing for transitive class containment as a feature of hierarchical classification

Three experiments investigated responding consistent with transitive class containment, a feature of hierarchical classification. Experiment 1 replicated key components of a preliminary attempt to model hierarchical classification (Griffee & Dougher, 2002) and tested for responding consistent with transitive class containment. Only 2 out of 5 participants showed the expected pattern. Experiment 2 tested whether repeated exposures to the Experiment 1 protocol would give rise to the expected pattern more reliably. None of 3 novel participants demonstrated the pattern. In Experiment 3, physically similar stimuli used in Experiments 1 and 2 were replaced across testing cycles by arbitrary stimuli. Transitive-class-containment-consistent responding was observed in all 3 novel participants. Implications, limitations and future research are discussed.     

Wishful thinking in the prediction of competitive outcomes

In each of two experiments, college students were assigned to two ad hoc groups (Team A and Team B) that competed in a dart-throwing contest. On each trial, one contestant from each team threw a single dart at a standard dart board, trying to come as close as possible to hitting the bull's-eye. Also on each trial, the other participants judged the likelihood that both the Team A contestant and the Team B contestant would come closer to hitting the bull's-eye. In both experiments (N=36 in Experiment 1; N=35 in Experiment 2), participants exhibited a strong wishful thinking effect. They judged the likelihood that their own team members would come closer to be greater than the likelihood that the opposing team members would come closer. Experiment 2 suggested that it was participants' desires, as opposed to some other variable associated with team membership, that influenced their predictions. Experiment 2 also showed that the size of the effect did not depend on whether participants believed that their predictions had been influenced by their team membership. These results help bridge the gap between previous experimental laboratory studies, which have produced inconsistent results, and correlational field studies of sports fans and voters, which have consistently produced large effects.     

Interpersonal attachment predicts identification with groups

We propose a model documenting the relationship between interpersonal attachment style and identification with groups. We hypothesized that following threat to a romantic interpersonal relationship higher attachment anxiety would be associated with lowered tendencies to identify with groups. In two studies using varied social groups we observed support for this hypothesis. In Experiment 1 we found that participants higher in attachment anxiety identified less with a salient ingroup after imagining a distressing argument with their romantic partner. In Experiment 2 we replicated these findings using an implicit measure of social identification and additionally observed a moderating role for attachment avoidance. We discuss the implications of these findings for theoretical models of interpersonal attachment and social identification.
