Collaboration and psychological ownership: how does the tension between the two influence perceived learning?

Collaborative writing may evoke conflict between individuals’ feeling of contribution and their sense of ownership toward the collective outcomes. The present study tested the relations between perceived psychological ownership, perceived quality of the product, and perceived learning in five experimental conditions: two collaborative, two sharing, and a control. Analysis of the changes made between versions revealed differences in quantity and in types of changes between collaboration, sharing, and control conditions. Results showed that collaboration may improve the perceived quality of the written product more than sharing or control. In addition, less intrusive collaboration seems to enhance the sense of perceived learning. The relation between perceived ownership and perceived learning was mediated by perceived quality of the written product. We conclude that students may avoid collaboration partly because they do not want to lose a sense of personal ownership or to lessen peer ownership.     

Contextual information modulates initial processes of syntactic integration: the role of inter- versus intrasentential predictions

The authors demonstrate that intersentential context may influence syntactic integration processes during online sentence comprehension, although this influence appears to be restricted to cases in which a contextual requirement must be fulfilled. By applying event-related brain potentials to the processing of clause-medial word order variations in German, the authors show that the local processing difficulty (a negativity from 300 to 450 ms) observed for object-initial sentences in a neutral context is also obtained in a (behaviorally) facilitating context in which the object is contextually given. By contrast, the processing pattern for a focused (questioned) initial object does not differ from that for a focused subject: both elicit a parietal positivity (280-480 ms) post-onset of the focused phrase. The authors interpret this early positivity as a general marker of focus integration, a process that appears to briefly supersede sentence-internal requirements.     

Effects of attachment styles on the experience of equity in heterosexual couples relationships

Employing one correlational and two experimental studies, this paper examines the influence of attachment styles (secure, anxious, avoidant) on a person's experience of equity in intimate relationships. While one experimental study employed a priming technique to stimulate the different attachment styles, the other involved vignettes describing fictitious characters with typical attachment styles. As the specific hypotheses about the single equity components have been developed on the basis of the attachment theory, the equity ratio itself and the four equity components (own outcome, own input, partner's outcome, partner's input) are analyzed as dependent variables. While partners with a secure attachment style tend to describe their relationship as equitable (i.e., they give and take extensively), partners who feel anxious about their relationship generally see themselves as being in an inequitable, disadvantaged position (i.e., they receive little from their partner). The hypothesis that avoidant partners would feel advantaged as they were less committed was only supported by the correlational study. Against expectations, the results of both experiments indicate that avoidant partners generally see themselves (or see avoidant vignettes) as being treated equitably, but that there is less emotional exchange than is the case with secure partners. Avoidant partners give and take less than secure ones.     

Why a "word order difference" is not always a "word order" difference: a reply to Weyerts,Penke, Münte,Heinze, and Clahsen

We present evidence that the supposed processing advantage for an SV_finO word order over an SOV_fin word order in German argued for by Weyerts, Penke, Münte, Heinze, and Clahsen (2002) is supported by neither experimental nor theoretical evidence. Specifically, we show (a) that the frontocentral negativity for an SOV_fin in comparison to an SV_finO word order in Weyerts et al.'s Experiments 2 and 3 is reducible to more general differences in the electrophysiological responses elicited by nouns versus verbs in a sentence context, and (b) that the P600 difference between the two word orders in Experiment 2, as well as the reading time differences in Experiment 1, result from the fact that the two supposedly ungrammatical conditions actually differ in their degree of ill-formedness. We conclude that there is no evidence for a processing disadvantage for SOV_fin, thus reconciling Weyerts et al.'s results on German sentence processing with the grammatical regularities of German.     

A Visual Illustration of Induction in Multilevel Methods: The Problem of Leaders Awarding Countervailing Merit Components

Purpose

The purpose of this study is to illustrate the use of a multilevel technique, Within and Between Analysis (WABA), for inductively investigating the impact of how supervisory groups influence the process of awarding merit raises (permanent) and performance bonuses (temporary). From a levels of analysis perspective, is this relationship best modeled at the individual subordinate, the whole supervisory-group, or the within-group level?

Design

Archival merit pay data for 2 years were obtained for 71 managers and professionals nested within 21 supervisory groups who encompassed the entire management hierarchy of a 500+ person-manufacturing plant.

Findings

What appeared to be a countervailing relationship at the individual level (r _total = ?.64***), in which raises and bonuses were negatively correlated, was found to be a countervailing relationship at the whole supervisory-group level (r _between = ?.79*** vs. r _within = ?.36*). Given the statistically significant differences between supervisory groups, an induction toward a whole-group effect was made. These countervailing findings were replicated at the group level in the subsequent year’s data.

Implications

The whole-group effect indicates that managers were attempting to create some type of within-group equity by (1) minimizing variability within their groups, and (2), at the same time, trading off raises for bonuses at the whole-group level.

Originality

The application of WABA focuses on testing entities as well as variables, and it can provide a generalizable method for investigating levels of analysis issues in merit pay programs without necessarily advocating that only one level of analysis is universally potent. WABA also allows for the inductive investigation of additional levels of analysis as well as a variety of boundary conditions.     

RT distributional analysis of cognitive-control-related brain activity in first-episode schizophrenia

Impairments in cognitive control are a defining feature of schizophrenia. Aspects of cognitive control include proactive control—the maintenance of task rules or goals to bias attention and maintain preparedness—and reactive control—the engagement of attention in reaction to changing cognitive demands. Proactive control is thought to be particularly impaired in schizophrenia. We sought to examine proactive and reactive control in schizophrenia, as measured by reaction time (RT) variability, and especially long RTs, which are thought to represent lapses in proactive control, during the Stroop paradigm. Furthermore, we sought to examine the neural underpinnings of lapses in proactive control and the subsequent engagement of reactive control in those with schizophrenia, as compared to healthy controls, using fMRI. We found that patients with schizophrenia displayed greater RT variability and more extremely long RTs than controls suggesting that proactive control was weaker in the schizophrenia than in the control group. All of the subjects engaged regions of the cognitive control network during long RTs, consistent with an engagement of reactive control following a failure in proactive control on these trials. The schizophrenia group, however, displayed significantly diminished activity in these regions relative to controls. Our results suggest increased failures in proactive control, but also impaired reactive control, in schizophrenia as compared to healthy subjects.     

Moderation of Stimulus Material on the Prediction of IQ with Infants' Performance in the Visual Expectation Paradigm: Do Greebles Make the Task More Challenging?

The objective of this study was to examine the role of the stimulus material for the prediction of later IQ by early learning measures in the Visual Expectation Paradigm (VExP). The VExP was assessed at 9 months using two types of stimuli, Greebles and human faces. Greebles were assumed to be associated with a higher load on working memory in comparison to human faces. IQ was assessed at 3 years and 4 months of age. Sixty‐four children participated at both assessments in this longitudinal study. The results show a moderation of the stimulus material on the prediction of IQ. With Greebles as stimulus material, a significant relationship between infants' learning and IQ was found. There was no relation when infants' learned in the VExP using human faces. Copyright © 2015 John Wiley & Sons, Ltd.     

On the origin of worries about modern health hazards: Experimental evidence for a conjoint influence of media reports and personality traits

Objective: Worries about health threatening effects of potential health hazards of modern life (e.g. electric devices and pollution) represent a growing phenomenon in Western countries. Yet, little is known about the causes of this growing special case of affective risk perceptions termed Modern Health Worries (MHW). The purpose of this study is to examine a possible role of biased media reports in the formation of MHW.

Design: In two experiments, we investigated whether typical television reports affect MHW. In Study 1, 130 participants were randomly assigned to a film on idiopathic environmental intolerance (IEI) or a control film about cystic fibrosis. In Study 2, 82 participants were randomly assigned to either a film on the dangers of electromagnetic fields or a control condition.

Main outcome measures: Increases in MHW after sensational media reports.

Results: In Study 1, only participants high on the personality trait of absorption revealed increased MHW after watching the IEI film. In Study 2, specifically worries about radiation were found to be elevated after watching the film on the dangers of electromagnetic fields compared to the control film.

Conclusion: The results of both studies reveal a significant and specific influence of sensational short mass media reports on MHW. The influence of potential moderators such as absorption remains to be clarified.     

Emotions and physical health in the second half of life: interindividual differences in age-related trajectories and dynamic associations according to socioeconomic status

The importance of socioeconomic status (SES) for psychological functioning over the life span is increasingly acknowledged in psychological research. The Reserve Capacity Model by Gallo and Matthews (2003) suggests that SES is not only linked to physical health but also to the experience of positive and negative emotions. Moreover, due to differential amounts of psychosocial resources, cross-domain associations between emotions and health might differ according to SES. The present study examined age-related developments in positive affect (PA), negative affect (NA), and physical health, as well as dynamic associations between health and emotions in the second half of life. We looked at differences in these trajectories and their interrelationships according to education as one aspect of SES. We used data of up to three waves spanning 12 years from the nationally representative German Ageing Survey (N = 3,847, AgeT1 = 40-85 years). Applying multiple-group dual change score models, we found differential age-related change in PA and physical health, but not in NA, in two groups differing in level of education. NA did only predict change in physical health in low-educated individuals, whereas physical health was equally strongly related to change in PA in both education groups. These results indicate that SES not only affects changes in physical health and emotional functioning but also their interrelationships.
