The role of interpersonal movement synchronisation in empathic functions: Insights from Tango Argentino and Capoeira

Although evidence points to a role for kinesthetic empathy (i.e. spontaneous interpersonal movement imitation and synchronisation) in social interaction, its relationship with emotional and cognitive aspects of empathy is unknown. We compared empathy in Tango and Capoeira experts, which crucially depend on ongoing, mutual interpersonal synchronisation, with empathy in practitioners of Salsa and Breakdance, respectively, which demand less interpersonal synchronisation but are comparable concerning movements and setting. Kinesthetic empathy was increased in the Tango and Capoeira groups. Although no group differences in other aspects of empathy were detected, kinesthetic empathy correlated with emotional and cognitive empathy. Taken together, trait kinesthetic empathy varies in the general population, and appears increased in synchronisation experts.     

The perception of nested affordances: An examination of expert climbers

Nested affordances in climbing comprise of multiple sequential actions, encompassing more than isolated reaching and grasping. This study examined the extent to which the perception of (multiple) nested affordances in climbing can be understood relative to body-scaled anthropometrics (arm span) and action-scaled (maximal action capabilities) measures, in relation to sequential task-goals of varying complexity. The utilisation of functionally equivalent actions during the actualisation of nested affordances was also investigated. Participants were required to estimate the maximal distance a handhold could be reached in four conditions of varying complexity: nested affordances (reach to Touch; reach to Grasp) vs. multiple nested affordances (reach to grasp with one hand followed by Removing the other hand from the starting handhold; reach to grasp with one hand followed by Moving up to another handhold). Ten expert climbers first had to estimate their maximal reaching distance in these different conditions (Touch, Grasp, Remove, Move Up) before performing the climbing movement. This sequence of estimation-action was repeated four times in each condition. Results revealed that action-scaling measures better captured nested affordances when multiple sequential behaviours are nested than body-scaled measures. Our findings also suggest that expert climbers utilise functionally equivalent movements during the realisation of multiple nested affordances (Remove and Move Up conditions).     

Spilling thoughts: configuring attentional resources in infants’ goal-directed actions

The focus and organization of attention in perception-action coupling is systematically examined in two studies involving 9 and 10 -month-old infants engaged in learning goal-directed behaviors. Experiment 1 (discrimination study) observed the influence of an attentionally demanding motor task on learning and cognition, while Experiment 2 (means-ends study) observed the influence of an attentionally demanding goal on motor planning and reaching performance. Taken together the results of these two experiments revealed that when mental processing resources were directed to thinking about movement, discrimination performance became compromised; conversely, when processing resources were directed to thinking about the goal-state, the motor planning and execution became compromised. These results suggest a “spilling forward” of thoughts onto actions and goal-states and thus an attention-driven cognition/action trade-off for infants’ goal-directed actions. Findings highlight the ultimate importance of emerging motor skills on cognition and are contextualized within the on-going dialogues and developmental debates surrounding perceptual-motor skill development and problem-solving strategies during the first year.     

The sound of you and me: Novices represent shared goals in joint action

People performing joint actions coordinate their individual actions with each other to achieve a shared goal. The current study investigated the mental representations that are formed when people learn a new skill as part of a joint action. In a musical transfer-of-learning paradigm, piano novices first learned to perform simple melodies in the joint action context of coordinating with an accompanist to produce musical duets. Participants then performed their previously learned actions with two types of auditory feedback: while hearing either their individual action goal (the melody) or the shared action goal (the duet). As predicted, participants made more performance errors in the individual goal condition than in the shared goal condition. Further experimental manipulations indicated that this difference was not due to different coordination requirements in the two conditions or perceptual dissimilarities between learning and test. Together, these findings indicate that people form representations of shared goals in contexts that promote minimal representations, such as when learning a new action together with another person.     

Perceptuomotor rules as prediction tools in (joint) action: The case of orientation perception

The human action system has a layered structure supporting a cascade of partially overlapping information processes in multiple, interlinked representational spaces. Apart from the mirror neuron system which through motor resonance mediates one's understanding of the action goals of one's partner, perceptuomotor rules like Fitts' law, the Isogony Principle, and sequencing heuristics provide further sources of prediction in (joint) action. The present study focuses on a perceptuomotor rule that describes how the orientation of framed, tilted objects is perceived and acted upon by individuals. In two experiments involving the Rod-and-Frame Illusion (RFI) participants were asked to perform delayed responses that consisted either of (1) making a perceptual judgment in a forced-choice paradigm, or (2) rotating and propelling a hand-held cylinder. Irrespective of response type, the effects of the RFI proved robust and constant. The relevance of the findings for prediction in joint-action tasks is discussed.     

The Ringelmann effect: Studies of group size and group performance

Ringelmann's classic finding—that the addition of co-workers in a rope-pulling task leads to a linear decrement in the individual group member's average performance—was reexamined experimentally. Study I attempted to replicate the effect, using groups of subjects ranging in size from 1 to 6. Performance dropped significantly as group size was increased from one individual to two or to three, but the addition of a fourth, fifth, or sixth member produced insignificant additional decrements; thus, the effect was not linear but curvilinear. Study II was designed to examine possible sources of performance loss, separating the factors of “coordination” and “motivation” loss (Steiner, 1972). The possibility of intermember incoordination was eliminated, while motivation loss remained free to vary: Each experimental subject pulled alone, and in “groups” where he believed there were from one to five other members. Once again, individual performance declined significantly with the addition of the first and second perceived co-worker, but then leveled off for perceived group sizes three to six. Some implications are discussed.     

Stick to the script: The effect of witnessing multiple actors on children’s imitation

What kinds of cues increase imitative fidelity in early childhood? The effects of multiple models and verbal framing were examined in preschool children (N = 259, 3–6-year-olds). Each participant was presented with one of eight possible combinations of type of modeling and verbal frame. The type of modeling involved: (i) a single model offering two demonstrations, (ii) two successive models each offering a single demonstration, (iii) two synchronous models each offering two demonstrations, or (iv) two synchronous models each offering a single demonstration. The verbal frame preceding the demonstrations emphasized either the instrumental outcome of the actions or their conventionality. Imitative fidelity was highest for the synchronous models (types iii and iv) and lowest for the single model (type i). Imitative fidelity was also higher for the convention-oriented than the outcome-oriented frame and higher for older than younger children. Children also provided more conventional explanations for their actions after viewing the synchronous models and after the convention-oriented framing. The results indicate that children’s imitative fidelity depends on the number of actors and the way the actions are framed.     

Respect the technique: Status-based respect increases minority group social cohesion with majority groups,while also increasing minority collective action tendencies

The present work explores the implications of respect for social change. Social change can be achieved via improved attitudes between minority and majority groups (i.e., social cohesion) or via action taken by minority groups (i.e., collective action). Recent work suggests that the social cohesion route to social change, in particular an emphasis on commonality, may be incompatible with the collective action route to social change. We suggest that social-cohesion strategies rooted in status-based respect may allow for social cohesion and collective action. We experimentally investigated the relative effects of a majority group communicating status-based respect and commonality, as compared to a control, on minority group members’ social cohesion with the majority group and willingness to engage in collective action. Status-based respect increased positive attitudes toward a majority group, relative to commonality and control, but was also associated with increased collective action tendencies. Implications for social change are discussed.     

The touch of King Midas: Collingwood on why actions are not events

It is the ambition of natural science to provide complete explanations of reality. Collingwood argues that science can only explain events, not actions. The latter is the distinctive subject matter of history and can be described as actions only if they are explained historically. This paper explains Collingwood’s claim that the distinctive subject matter of history is actions and why the attempt to capture this subject matter through the method of science inevitably ends in failure because science explains events, not actions. It argues that Collingwood’s defence of the methodological autonomy of history vis-à-vis natural science is not based on a commitment to human exceptionalism, i.e. the exclusion of human beings and their doings from the rest of nature, but on the view that explanations which appeal to norms are different in kind from explanations which appeal to empirical regularities. Given the close relationship between the method and the subject matter of a form of inquiry, actions elude any attempt to explain them through the scientific method because the application of this method entails that what is thus explained is not an action but an event.     

Profiling Korean sex crimes: Offender characteristics and crime scene actions

The present study aimed to examine the demographic information of sex offenders in South Korea and explore whether a U.K. thematic model of criminal behaviour could be replicated in the Korean context. The 27 variables of crime scene actions derived from 50 Korean sexual offences through a content analysis were analysed with smallest space analysis. Chi‐square was also administered to explore the differences in offender characteristics among behavioural themes. Consequently, three separate action themes, hostility–involvement, theft, and control, were revealed. Next, each case was assigned to one of the dominant or hybrid themes, with 84% of the total cases being classified to the dominant themes. Moreover, there were significant differences in four offender characteristics between the themes: “previous conviction of robbery,” “previous conviction of sexual crime,” “knowing the victim,” and “vehicle use.” These outcomes have implications for the development of the Korean profiling system.     

Solidarity across group lines: Secondary transfer effect of intergroup contact,perceived moral distance,and collective action

We tested, in three studies, whether the generalization of contact effects from primary to secondary outgroups—the secondary transfer effect (STE)—occurs for collective action. The results supported a serial mediation model: contact with immigrants by advantaged group members (Italians: Study 1, N = 146, 121 females, M_age = 28.31 years; Study 3, N = 406, 239 females, M_age = 36.35; British people, Study 2, N = 160, 113 females, M_age = 32.31) was associated with lower perceived moral distance toward primary outgroups, which in turn was associated with more positive attitudes and greater collective action intentions toward primary outgroups, and lower perceived moral distance toward secondary outgroups. Lower perceived moral distance toward secondary outgroups and stronger collective action intentions toward the primary outgroup were associated with higher collective action intentions toward secondary outgroups (results were inconsistent for attitudes). We discuss the findings with a focus on how a consideration of perceived moral distance extends current theorizing, and the relevance of generalized prejudice for the STE.     

The joint flanker effect and the joint Simon effect: On the comparability of processes underlying joint compatibility effects

Previous studies observed compatibility effects in different interference paradigms such as the Simon and flanker task even when the task was distributed across two co-actors. In both Simon and flanker tasks, performance is improved in compatible trials relative to incompatible trials if one actor works on the task alone as well as if two co-actors share the task. These findings have been taken to indicate that actors automatically co-represent their co-actor’s task. However, recent research on the joint Simon and joint flanker effect suggests alternative non-social interpretations. To which degree both joint effects are driven by the same underlying processes is the question of the present study, and it was scrutinized by manipulating the visibility of the co-actor. While the joint Simon effect was not affected by the visibility of the co-actor, the joint flanker effect was reduced when participants did not see their co-actors but knew where the co-actors were seated. These findings provide further evidence for a spatial interpretation of the joint Simon effect. In contrast to recent claims, however, we propose a new explanation of the joint flanker effect that attributes the effect to an impairment in the focusing of spatial attention contingent on the visibility of the co-actor.     

Choosing between conciliatory and oppositional leaders: The role of out‐group signals and in‐group leader candidates' collective action tactics

In this paper, we examine the role of out‐group signals and in‐group leader tactics in the choice and evaluation of rival in‐group leader candidates. Study 1 found preference for a negotiating in‐group leader over an oppositional leader, mediated by perceived leader effectiveness and prototypicality. In Study 2, participants chose a leader who had received out‐group endorsement, and in Studies 3 and 4, participants chose a negotiating in‐group leader where the out‐group was prepared to negotiate and an oppositional leader where the out‐group was not prepared to negotiate. In the latter three studies, there was evidence for participants being strategic in their choices: effects were mediated by effectiveness but not prototypicality. These findings suggest our understanding of collective action will be enriched through attention to the situational cues provided by out‐groups, and to the context of competing voices of collective action leadership.     

The effect of personal and group discrimination on the subjective well-being of people with mental illness: the role of internalized stigma and collective action intention

The goal of this study is to test a model in which personal discrimination predicts internalized stigma, while group discrimination predicts a greater willingness to engage in collective action. Internalized stigma and collective action, in turn, are associated to positive and negative affect. A cross-sectional study with 213 people with mental illness was conducted. The model was tested using path analysis. Although the data supported the model, its fit was not sufficiently good. A respecified model, in which a direct path from collective action to internalized stigma was added, showed a good fit. Personal and group discrimination appear to impact subjective well-being through two different paths: the internalization of stigma and collective action intentions, respectively. These two paths, however, are not completely independent, as collective action predicts a lower internalization of stigma. Thus, collective action appears as an important tool to reduce internalized stigma and improve subjective well-being. Future interventions to reduce the impact of stigma should fight the internalization of stigma and promote collective action are suggested.     

Children’s scale errors are a natural consequence of learning to associate objects with actions: A computational model

Young children sometimes attempt an action on an object, which is inappropriate because of the object size—they make scale errors. Existing theories suggest that scale errors may result from immaturities in children's action planning system, which might be overpowered by increased complexity of object representations or developing teleofunctional bias. We used computational modelling to emulate children's learning to associate objects with actions and to select appropriate actions, given object shape and size. A computational Developmental Deep Model of Action and Naming (DDMAN) was built on the dual‐route theory of action selection, in which actions on objects are selected via a direct (nonsemantic or visual) route or an indirect (semantic) route. As in case of children, DDMAN produced scale errors: the number of errors was high at the beginning of training and decreased linearly but did not disappear completely. Inspection of emerging object–action associations revealed that these were coarsely organized by shape, hence leading DDMAN to initially select actions based on shape rather than size. With experience, DDMAN gradually learned to use size in addition to shape when selecting actions. Overall, our simulations demonstrate that children's scale errors are a natural consequence of learning to associate objects with actions.     

Rowing together: Interpersonal coordination dynamics with and without mechanical coupling

Although most research on interpersonal coordination focuses on perceptual forms of interaction, many interpersonal actions also involve interactions of mechanical nature. We examined the effect of mechanical coupling in a rowing task from a coupled oscillator perspective: 16 pairs of rowers rowed on ergometers that were physically connected through slides (mechanical coupling condition) or on separate ergometers (no mechanical coupling condition). They rowed in two patterns (in- and antiphase) and at two movement frequencies (20 and 30 strokes per minute). Seven out of sixteen pairs showed one or more coordinative breakdowns, which only occurred in the antiphase condition. The occurrence of these breakdowns was not affected by mechanical coupling, nor by movement frequency. For the other nine pairs, variability of steady state coordination was substantially lower in the mechanical coupling condition. Together, these results show that the increase in coupling strength through mechanical coupling stabilizes coordination, even more so for antiphase coordination.     

Bias and learning in temporal binding: Intervals between actions and outcomes are compressed by prior bias

It has consistently been shown that agents judge the intervals between their actions and outcomes as compressed in time, an effect named intentional binding. In the present work, we investigated whether this effect is result of prior bias volunteers have about the timing of the consequences of their actions, or if it is due to learning that occurs during the experimental session. Volunteers made temporal estimates of the interval between their action and target onset (Action conditions), or between two events (No-Action conditions). Our results show that temporal estimates become shorter throughout each experimental block in both conditions. Moreover, we found that observers judged intervals between action and outcomes as shorter even in very early trials of each block. To quantify the decrease of temporal judgments in experimental blocks, exponential functions were fitted to participants’ temporal judgments. The fitted parameters suggest that observers had different prior biases as to intervals between events in which action was involved. These findings suggest that prior bias might play a more important role in this effect than calibration-type learning processes.     

The good,the bad and the central of group identification: Evidence of a U‐shaped quadratic relation between in‐group affect and identity centrality

The present research investigates the interrelation between two widely studied dimensions of social group identity—in‐group affect and centrality. Specifically, we test the validity of a quadratic curvilinear relation between in‐group affect and identity centrality. We propose that group members who feel either decidedly positive affect or decidedly negative affect towards their group are more likely to feel that their identity is a central component of their self‐concept relative to group members with neutral affect. We find evidence for a quadratic relation between in‐group affect and identity centrality with respect to people's cultural identity (N = 512), ethnic identity (N = 462), religious identity (N = 61, N = 384) and racial identity (N = 3600, N = 2400). Theoretical and practical implications for the measurement and conceptualization of group identification are discussed. Copyright © 2016 John Wiley & Sons, Ltd.
