Processing focus structure and implicit prosody during reading: differential ERP effects

Several recent studies have shown that focus structural representations influence syntactic processing during reading, while other studies have shown that implicit prosody plays an important role in the understanding of written language. Up until now, the relationship between these two processes has been mostly disregarded. The present study disentangles the roles of focus structure and accent placement in reading by reporting event-related brain potential (ERP) data on the processing of contrastive ellipses. The results reveal a positive-going waveform (350-1300 ms) that correlates with focus structural processing and a negativity (450-650 ms) interpreted as the correlate of implicit prosodic processing. The results suggest that the assignment of focus as well as accent placement are obligatory processes during reading.     

The role of a mentoring group for family therapy trainees and therapists of color

This article discusses the development, process, and impact of a mentoring group for family therapists of color. A within-group process for trainees of color in a predominantly White institution can provide a valuable resource for support, validation, empowerment, and collective action. The article examines how such mentoring promotes the effectiveness of therapists of color, as well as the practices and goals of social justice and diversity within training institutions and the field in general. Reflections and recommendations for implementing such a group are offered, as well as a personal narrative of a group member's experience of finding her voice in the group.     

Leader-member exchange and citizenship behaviors: a meta-analysis

This article provides a meta-analytic review of the relationship between the quality of leader-member exchanges (LMX) and citizenship behaviors performed by employees. Results based on 50 independent samples (N = 9,324) indicate a moderately strong, positive relationship between LMX and citizenship behaviors (rho = .37). The results also support the moderating role of the target of the citizenship behaviors on the magnitude of the LMX-citizenship behavior relationship. As expected, LMX predicted individual-targeted behaviors more strongly than it predicted organizational targeted behaviors (rho = .38 vs. rho = .31), and the difference was statistically significant. Whether the LMX and the citizenship behavior ratings were provided by the same source or not also influenced the magnitude of the correlation between the 2 constructs.     

Explaining affective linkages in teams: individual differences in susceptibility to contagion and individualism-collectivism

To expand on the understanding of how affective states are linked within teams, the authors describe a longitudinal study examining the linkages between team members' affective states over time. In a naturalistic team performance setting, they found evidence that the average affective state of the other team members was related to an individual team member's affect over time, even after controlling for team performance. In addition, they found that these affective linkages were moderated by individual differences in susceptibility to emotional contagion and collectivistic tendencies such that the strength of the linkage was stronger for those high in susceptibility and those with collectivistic tendencies. Implications for research and practice are discussed.     

Intentions and expectations in temporal binding

Recently, it has been shown that the perceived times of voluntary movements and their effects are perceived as shifted towards each other. This temporal binding phenomenon was explained by an integrated representation of movement and effect, facilitating operant learning and the experience of intentionality. Here, we investigated whether temporal binding depends on explicit intentional attributions. In Experiment 1, participants intended to either produce or avoid producing an effect (a tone) by the timing of their movements, with the ratio of success being fixed at 2:1. In Experiments 2 and 3, the influence of the action-effect contingency ratio on temporal binding was controlled for by removing the intentional attribution of the effect. The results indicate that temporal binding is a general associative mechanism that facilitates the learning of movement-effect contingencies. Beyond that, temporal binding is sensitive to explicit intentional attributions, which selectively enhance the link between an intentional movement and the effect a moving agent intends to produce.     

Self‐regulation of Group Members: The Case of Regulatory Focus

For a long time, research on motivation and (inter)group behaviour mainly focused on needs and motives, but did not take self‐regulation (i.e., the processes underlying motivated action) into account. Similarly, self‐regulation research concentrated on the regulation of the personal self, but did not study the regulation of the social self. The current article summarizes work applying self‐regulation approaches to intergroup behaviour. Within this approach, it has been shown (a) that the social self is regulated based on the same mechanisms as the personal self, (b) that intergroup contexts impact on group members’ self‐regulation strategies, and (c) that the fit between an individual's self‐regulation strategy and the behavioural options provided by the group impact on group liking and potentially also on the integration of the group into the self‐concept. The relation between current and earlier approaches to motivation in groups and further avenues for research on group‐based self‐regulation are discussed.     

Effect of click trains on duration estimates by people with Parkinson's disease

Patients with a diagnosis of Parkinson's disease and age- and IQ-matched controls estimated the duration of short 500-Hz tones (325-1,225 ms), on trials where the tone was either preceded by 3 s of 5-Hz clicks, or presented without clicks. The click manipulation had been shown in earlier studies with student participants to make verbal estimates longer. Patients were tested both on and off their dopaminergic medication, and controls were also tested in two sessions. Verbal estimates were markedly and significantly longer on trials with clicks than on those without clicks for both the patients and the controls, but there were no significant performance differences between patients or controls, nor between the on and off medication sessions in the patients. The study shows that a manipulation of subjective time, which has had small but consistent effects in student participants, also affects timing in patients and adds to a growing body of evidence that timing in patients with Parkinson's disease may in many cases have the same characteristics as those of neurologically intact control groups.

Passion for Driving and Aggressive Driving Behavior: A Look at Their Relationship

The purpose of the present research was to investigate the relationship between passion for driving and aggressive driving behavior in 3 studies. Study 1 examined the association between passion and aggressive driving behavior in a sample of undergraduate students. Results showed that an obsessive passion for driving was associated with aggressive driving behavior, while harmonious passion was not. Study 2 replicated these results with an ecologically valid sample of community‐dwelling drivers. Finally, Study 3 replicated the results obtained in Studies 1 and 2 in a laboratory setting using a driving simulator under controlled frustrating driving situations with judges' assessment of aggressive driving behavior. Study 3 also showed that the emotion of anger mediated the obsessive‐passion/aggressive‐driving‐behavior relationship.     

Investigating the role of conflict resolution in memory updating by means of the one-back choice RT task

The current study is inspired by recent findings, which suggest that conflict is involved in the updating of memory representations. It directly addresses the relation between memory updating and conflict resolution by means of the one-back choice reaction time (RT) task, an updating task, which requires participants to postpone their response to stimulus n until the subsequent stimulus n + 1 has been presented. In three experiments, a more detailed analysis of the one-back choice RT task is presented in order to further identify the role of conflict resolution in memory updating. The findings demonstrate that the one-back choice RT task, which allows motor preparation just like a simple RT task, is in fact performed slower than a simple RT task because it additionally involves conflict resolution. It is further shown that also the response–stimulus interval of the one-back task involves processes that affect the amount of conflict in the task. In the "General discussion", the theoretical relevance of these findings for the concept of updating is discussed.
