Your own actions influence how you perceive other people: A misattribution of action appraisals

The attribution of personal traits to other persons depends on the actions the observer performs at the same time (Bach & Tipper, 2007). Here, we show that the effect reflects a misattribution of appraisals of the observers' own actions to the actions of others. We exploited spatial compatibility effects to manipulate how fluently-how fast and how accurately-participants identified two individuals performing sporty or academic actions. The traits attributed to each person in a subsequent rating task depended on the fluency of participants' responses in a specific manner. An individual more fluently identified while performing the academic action appeared more academic and less sporty. An individual more fluently identified while performing the sporty action appeared sportier. Thus, social perception is-at least partially-embodied. The ease of our own responses can be misattributed to the actions of others, affecting which personal traits are attributed to them.     

Implicit action encoding influences personal-trait judgments

When an observed action (e.g., kicking) is compatible to a to be produced action (e.g., a foot-key response as compared to a finger-key response), then the self-produced action is more fluent, that is, it is more accurate and faster. A series of experiments explore the notion that vision-action compatibility effects can influence personal-trait judgments. It is demonstrated that when an observed individual carries out an action that is compatible with the participants' response, (1) this individual is identified more fluently, and (2) the observed individual's personality is attributed with the properties of the observed action. For example, if it is easier to identify one individual with a foot-response when he is seen kicking a ball, as compared to typing, he is perceived to be more 'sporty'. In contrast, if it is easier to identify one individual with a finger response when he is seen typing as compared to kicking a ball, he is associated with the 'academic' trait. These personal-trait judgment effects can be observed with explicit measures, where participants are asked to rate the sporty/academic nature of the person on a scale. They are also obtained when implicit measures are taken in a priming task, where participants are never explicitly asked to rate the personalities of the individuals. A control experiment rules out that these personal-trait effects are merely due to an association of motor responses (foot, finger) to individuals while identifying them, but that these effects depend on a prior manipulation of vision-action fluency.     

The illusion of courage in social predictions: Underestimating the impact of fear of embarrassment on other people

The results of two experiments support the thesis that emotional perspective taking entails two judgments: a prediction of one’s own preferences and decisions in a different emotional situation, and an adjustment of this prediction to accommodate perceived differences between self and others. Participants overestimated others’ willingness to engage in embarrassing public performances—miming (Experiment 1) and dancing (Experiment 2)—in exchange for money. Consistent with a dual judgment model, this overestimation was greater among participants facing a hypothetical rather than a real decision to perform. Further, participants’ predictions of others’ willingness to perform were more closely correlated with self-predictions than with participants’ estimates of others’ thoughts about the costs and benefits of performing.     

Intentionality as a constituting condition for the own self—and other selves

Introspectively, the awareness of actions includes the awareness of the intentions accompanying them. Therefore, the awareness of self-generated actions might be expected to differ from the awareness of other-generated actions to the extent that access to one’s own and to other’s intentions differs. However, we recently showed that the perceived onset times of self- vs. other-generated actions are similar, yet both are different from comparable events that are conceived as being generated by a machine. This similarity raises two interesting possibilities. First we could infer the intentions of others from their actions. Second and more radically, we could equally infer our own intentions from the actions we perform rather than sense them. We present two new experiments which investigate the role of action effects in the awareness of self- and other-generated actions by means of measuring the estimated onset time. The results show that the presence of action effects is necessary for the similarity of awareness of self- and other-generated actions.     

Observing one's hand become anarchic: an fMRI study of action identification

The self seems to be a unitary entity remaining stable across time. Nevertheless, current theorizing conceptualizes the self as a number of interacting sub-systems involving perception, intention and action (self-model). One important function of such a self-model is to distinguish between events occurring as a result of one’s own actions and events occurring as the result of somebody else’s actions. We conducted an fMRI experiment that compared brain activation after an abrupt mismatch between one’s own movement and its visual consequences with an abrupt mismatch between one’s own movement and somebody else’s visually perceived hand movement. A right fronto-parietal network was selectively active during a sudden mismatch between one’s own observed and performed hand action.     

The emergence of personality: Dynamic foundations of individual variation

We conceptualize personality and individual variation from the perspective of dynamical systems. People’s thoughts, feelings, and predispositions for action are inherently dynamic, displaying constant change due to internal mechanisms and external forces, but over time the flow of thought and action converges on a narrow range of states—a fixed-point attractor—that provides cognitive, affective, and behavioral stability. An attractor for personal dynamics develops through two mechanisms: the synchronization of individuals’ internal states in social interaction, and the self-organization of thoughts and feelings with respect to a higher-order property (e.g., goal, self-concept). We present formal models of both processes and instantiate each in computer simulations. Discussion centers on the implications of interpersonal synchronization and self-organization dynamics for issues in personality psychology, including shared vs. non-shared environmental influences on personality development, the expression of personality in social interaction, personal stability vs. change, personal vs. situational causation, and the emergence of self-concept.     

Effects of another person’s fair treatment on one’s own emotions and behaviors: The moderating role of how much the other cares for you

This research examined whether the extent of fair treatment of another affects one’s own reactions and whether helpful and supportive behavior from this other towards oneself moderates this impact. We predicted fair treatment of the other would affect the participant’s own emotions and behaviors with respect to a common task, but only if this other was willing to give help and support. In addition, we expected that positive or negative emotions would underlie, respectively, a participant’s willingness to cooperate or their willingness to leave the task. Results from a scenario experiment, a cross-sectional survey, and a laboratory experiment supported our predictions. We conclude that how fairly another is treated matters in its effects on one’s emotional and behavioral reactions and that procedural justice for others can also be considered important organizational information in shaping one’s own feelings and actions for employees.     

Schizotypal personality traits and prediction of one's own movements in motor control: what causes an abnormal sense of agency?

Background. Positive schizophrenic symptoms, especially passivity phenomena, including auditory hallucinations, may be caused by an abnormal sense of agency, which people with schizotypal personality traits also tend to exhibit. A sense of agency asserts that it is oneself who is causing or generating an action. It is possible that this abnormal sense of self-agency is attributable to the abnormal prediction of one’s own movements in motor control. Method. We conducted an experiment using the “disappeared cursor” paradigm in which non-clinical, healthy participants were required to click on a target using an invisible mouse cursor. Prediction error was defined as the distance between the target and the click point. Results. The results showed that schizotypal personality traits, but not depressive or anxious traits, were correlated with deficits in predicting movements of the subjects’ left hand. In particular, auditory hallucination proneness had the strongest relationship with movement prediction error. In this report, we also discuss the error tendency (overestimations or underestimations of one’s own movements). Conclusions. This finding is in accordance with the idea that passivity phenomena or proneness may be caused by the abnormal prediction of one’s own actions or movements.     

The role of motor simulation in action perception: a neuropsychological case study

Research on embodied cognition stresses that bodily and motor processes constrain how we perceive others. Regarding action perception the most prominent hypothesis is that observed actions are matched to the observer’s own motor representations. Previous findings demonstrate that the motor laws that constrain one’s performance also constrain one’s perception of others’ actions. The present neuropsychological case study asked whether neurological impairments affect a person’s performance and action perception in the same way. The results showed that patient DS, who suffers from a frontal brain lesion, not only ignored target size when performing movements but also when asked to judge whether others can perform the same movements. In other words DS showed the same violation of Fitts’s law when performing and observing actions. These results further support the assumption of close perception action links and the assumption that these links recruit predictive mechanisms residing in the motor system.     

Social control of health behavior: associations with conscientiousness and neuroticism

Despite considerable research demonstrating associations of conscientiousness and neuroticism with health-related behavior, our understanding of how and why these traits are related to lifestyle is limited. This study examined the social regulation of health behavior in a probability sample of 509 household residents who completed a Random Digit Dial (RDD) telephone survey. Results suggest that the social regulation of health behavior experienced by highly conscientious individuals has more to do with their own internalized notions of responsibility and obligation to others than to specific actions by others aimed at influencing their health habits. In contrast, individuals with higher neuroticism experience more overt attempts by others to influence their health habits but have more negative affective and behavioral responses to these social influence attempts. Findings suggest that elucidating the distinct social influence processes that operate for conscientiousness and neuroticism may further understanding of how these traits are related to health behaviors and status.     

Sociomotor action control

Our actions affect the behavior of other people in predictable ways. In the present article, we describe a theoretical framework for action control in social contexts that we call sociomotor action control. This framework addresses how human agents plan and initiate movements that trigger responses from other people, and we propose that humans represent and control such actions literally in terms of the body movements they consistently evoke from observers. We review evidence for this approach and discuss commonalities and differences to related fields such as joint action, intention understanding, imitation, and interpersonal power. The sociomotor framework highlights a range of open questions pertaining to how representations of other persons’ actions are linked to one’s own motor activity, how specifically they contribute to action initiation, and how they affect the way we perceive the actions of others.     

Effects of global and contextualized personality on relationship satisfaction

Researchers have made great strides in conceptualizing and assessing contextualized personality—how people’s personalities vary across different contexts (e.g., among friends, co-workers, and relationship partners). We investigated how global and contextualized personality traits are linked to relationship satisfaction. In Study 1, longitudinal associations between global and contextualized personality and relationship satisfaction were examined in a sample of adults in committed dating relationships. Study 2 investigated actor and partner effects of global and contextualized personality on relationship satisfaction in undergraduate couples. Study 3 used observer ratings of contextualized personality traits expressed in couples’ daily Instant Messages (IMs). These results demonstrate that contextualized personality—in particular neuroticism—is linked to the quality of both current and future romantic relationships.     

Reading your own lips: Common-coding theory and visual speech perception

Common-coding theory posits that (1) perceiving an action activates the same representations of motor plans that are activated by actually performing that action, and (2) because of individual differences in the ways that actions are performed, observing recordings of one’s own previous behavior activates motor plans to an even greater degree than does observing someone else’s behavior. We hypothesized that if observing oneself activates motor plans to a greater degree than does observing others, and if these activated plans contribute to perception, then people should be able to lipread silent video clips of their own previous utterances more accurately than they can lipread video clips of other talkers. As predicted, two groups of participants were able to lipread video clips of themselves, recorded more than two weeks earlier, significantly more accurately than video clips of others. These results suggest that visual input activates speech motor activity that links to word representations in the mental lexicon.     

Action observation modulates auditory perception of the consequence of others' actions

We can easily discriminate self-produced from externally generated sensory signals. Recent studies suggest that the prediction of the sensory consequences of one’s own actions made by forward model can be used to attenuate the sensory effects of self-produced movements, thereby enabling a differentiation of the self-produced sensation from the externally generated one. The present study showed that attenuation of sensation occurred both when participants themselves performed a goal-directed action and when they observed experimenter performing the same action, although they clearly reported that the tones were produced by other during action observation and by themselves during their own action. These results suggest that sensory prediction of action modulates ongoing auditory processing irrespective of who produces the sounds and that the explicit judgment of agency does not necessarily rely on the same mechanisms on which implicit perceptual measures such as sensory attenuation rely.     

Infant's perception of goal-directed actions performed by a mechanical device

The present work investigated whether by the end of the first year, infants interpret actions performed by a mechanical device as goal-directed and why they would do so. Using a modified version of the Woodward (1998) habituation paradigm, 9- and 12-month-old infants were tested in a condition in which they saw a mechanical claw performing an action (Study 1). When infants viewed the claw grasping and transporting objects to the back of a stage, 12-month-old but not 9-month-old infants interpreted the action as goal-directed. In Study 2, 9-month-olds received prior to habituation an information phase showing infants how a human held and operated the claw. This enrichment of infants’ knowledge enabled 9-month-old infants to interpret the action display as goal-directed. The role of the developing means-end understanding and tool-use for infants’ interpretation of actions performed by a mechanical device is discussed.     

Pursuing Goals with Others

This article explores motivation in a social context: how people pursue goals with others, with information on others, and for the self and others. As people incorporate close others into their extended selves (Aron et al., 1991 ), they begin to treat others' actions and outcomes as partially their own. This tendency, in turn, has implications for coordinating goal pursuits with others and for the preference for actions that maximize the total benefits for the self and others. To demonstrate these principles – coordination and joint‐benefits maximization – we first explore coordination in pursuing goals with others (i.e., working in teams), showing that people respond to others' actions and lack of action similarly to how they respond to their own actions and lack of action. We next explore coordination in pursuing goals with information on others, showing that people conform to others' preferences and attitudes yet choose actions that complement others' actions. Finally, we review research on pursuing goals for the self and others, showing that people wish to maximize the total benefits for the group.     

Determinants of social perception in a naturalistic setting

Based upon the assumption that personality traits exist more in the eye of the observer than is actually reflected in the actions of the actor, Jones and Nisbett have proposed that a negative relationship exists between familiarity with an actor's behavioral history and the tendency to attribute traits to that individual. An alternative viewpoint is suggested by the present research. Members of a college fraternity attributed more personality traits to themselves than were attributed to them by their fellow members. In addition, the fraternity members tended to offer more dispositional attributions to other members with whom they were more familiar. Furthermore, evidence is presented that is suggestive of the validity of these attributions. It is concluded that the attribution of personality traits provides attributors with information that is both veridical and useful in guiding social interactions.     

The impact of information from similar or different advisors on judgment

People rely on others’ advice to make judgments on a daily basis. In three studies, we examine the differential impacts of similarity between the source of that advice and the person making the judgment in two settings: judging others’ behavior and judging one’s own actions. We find that similarity interacts with the target of the judgment. In particular, information received from a different advisor is more heavily weighed than from a similar advisor in judging others’ actions, but information from a similar advisor is more heavily weighed than from a different advisor in judging one’s own. We provide two potential explanations for this interaction, difficulty of the judgment and informativeness of the advice. Our analyses show a moderated mediating role of informativeness and difficulty in the relationship between the advisor’s similarity by judgment type interaction and advice use.
