Assessing different aspects of pretend play within a play setting: Towards a standardized assessment of pretend play in young children

The present study suggests a method with which to assess the interrelations between different types of pretend play. In contrast to standard methods in this area, the various types of pretend play were measured within an interactive play scenario. The pretend play tasks were included in a semi‐structured play sequence and presented to young children between 24 and 30 months of age (N=30). Self‐ and doll‐directed pretence, object substitution, pretence with realistic objects, and self‐initiated pretend play, as well as the understanding that an object had been given two identities was tested. The capacity for dual representation was assessed by asking for the real and pretend identity of an object. Age differences were found in the overall score for elicited pretence but not for all items separately. Individual items also differed in difficulty and thus are of potential use for assessing intraindividual differences in pretend play. Findings are discussed in the context of current theories and methods concerning the development and assessment of pretend play.     

Affective influences on within-person changes in work performance as mediated by attentional focus

A great deal of research has investigated the performance consequences of affective experiences at work, but the mediating mechanisms that explain these consequences remain understudied. In this study, we used experience sampling method to examine within-person relationships between changes in affective states and episodic performance, as mediated by attentional allocation and regulation. Our findings show that within-person changes in negative affective states have a concurrent association with episodic performance as mediated by reduced attentional allocation and regulation, while positive affective states are associated with better performance, as mediated by enhanced attentional allocation and regulation. Our results are discussed in terms of their implications for understanding the performance and attentional consequences of affective states at work.     

Evidence for goal-independent attentional capture from validity effects with unexpected novel color cues—A response to Burnham (2007)

Can a stimulus capture attention independent of the observer’s goals and intentions? In a recent review, (Burnham, Psychonomic Bulletin &; Review, 14, 392–422, 2007) argued that there is no convincing evidence that attention capture is ever completely independent of the goals and intentions of the observer. By contrast, surprise capture studies have shown that a color singleton can capture attention on its unannounced first occurrence, if it is new and unexpected, and hence is not part of the intentional set. However, the evidence from surprise capture studies has been criticized on methodological grounds. Here, we tested surprise capture in a new paradigm that avoids previous methodological complications. The results refute the prior criticisms and reinstate surprise capture as prime evidence for goal-independent capture.     

Psychometric properties of the French and English versions of the Vancouver Obsessional-Compulsive Inventory and the Symmetry Ordering and Arranging Questionnaire

The Vancouver Obsessional-Compulsive Inventory (VOCI) and the Symmetry Ordering and Arranging Questionnaire (SOAQ) are self-report measures that assess a wide variety of symptoms and features of obsessive-compulsive disorder (OCD) including checking, contamination, obsessions, hoarding, "just right", indecisiveness, and symmetry, ordering and arranging obsessions and compulsions. The original English versions of the VOCI and SOAQ have been shown to demonstrate excellent psychometric properties. The present study examined the reliability and validity of French translations of these measures in a non-clinical sample, and also involved the collection of supplementary psychometric information about the English versions of the scales from a new sample. Volunteer undergraduate students completed questionnaire packages including the VOCI and SOAQ, as well as measures of obsessive-compulsive, phobic and depressive symptomatology in their native language of either French or English. Results indicate that the French versions of the VOCI and SOAQ demonstrate similar and excellent psychometric properties to the English versions and that these measures are highly valid and reliable assessment tools for use in clinical and research applications in both languages.     

Organizational citizenship behavior in work groups: a group norms approach

Although the relationship between unit-level organizational citizenship behavior (OCB) and unit outcomes has been well established in recent years, the conceptual development of OCB at the unit level of analysis has not been adequately addressed. In an effort to fill this conceptual gap and to spur future research, the authors apply the literature on group norms to the concept of OCB. The resulting framework suggests a cyclical relationship between individual- and group-level processes and ultimately offers an explanation for how OCB norms are established and maintained in work groups. The authors demonstrate how this framework incorporates past research on the relationship between unit-level OCB and unit outcomes and how it extends previous research by suggesting multiple directions for future efforts related to unit-level OCB.     

Neurocognitive impairment does not predict treatment outcome in obsessive-compulsive disorder

There is conflicting evidence pertaining to whether or not neurocognitive task performance at baseline predicts treatment response in obsessive-compulsive disorder (OCD). In the present study, we administered a set of executive neurocognitive tests with a putative sensitivity for treatment outcome to a sample of 138 OCD patients. Additionally, subjective neurocognitive dysfunction was determined via a questionnaire. All patients participated in a cognitive-behavioural treatment program (CBT). Results showed that responders (n = 73) did not differ from non-responders (n = 65) on any of the parameters except for decreased performance on the delayed alternation test (p < .1, effect size: .61). A subsidiary analysis revealed that slowing on the Trail-Making Test A and an enhanced rate of perserveration errors on the Wisconsin Card Sorting Test predicted poor outcome for the treatment of compulsions. It is concluded that neurocognitive impairment does not represent a reliable early warning sign for non-response to CBT.     

Interculturalism: A new diversity ideology with interrelated components of dialogue,unity, and identity flexibility

Increased cultural diversity has led to considerable debate on how to best promote intergroup harmony within pluralistic nations. In the current research, we consider the nature of interculturalism, a new diversity ideology extensively discussed by political philosophers and policy-makers in Europe and beyond. Interculturalism consists of three interrelated components of dialogue, unity, and identity flexibility. Using data (N = 2,364) from three national surveys in two ethnically diverse nations (Netherlands and USA), we test a new measure of interculturalism and establish its independence from multiculturalism and assimilation. We then demonstrate that interculturalism predicts positive intergroup outcomes, over and above multiculturalism, and is in a theoretically meaningful way related to various criterion measures. Collectively, these studies establish the uniqueness of interculturalism from multiculturalism and demonstrate its promise for improving intergroup relations in culturally diverse nations.     

Bullying in elementary school, high school, and college

This study investigated the continuity in being a bully, victim, or bully-victim from elementary school through college in 119 undergraduates. Of 25 who bullied in college, 18 (72%) had been bullied in high school and elementary school. Of 26 bullies in college, 14 (53.8%) had been bullies in high school and elementary school. Of 12 bully-victims in college, 5 (41.6%) had been bully-victims in high school and elementary school. There were significant positive correlations between being a bully in college, high school, and elementary school, and being bullied in college and high school, and high school and elementary school, and between being both a bully and victim in elementary school, a bully and victim in high school, and a bully and victim in college.     

Imagination inflation is a fact, not an artifact: A reply to Pezdek and Eddy

Pezdek and Eddy (2001) claim to prove that imagination inflation is a spurious effect caused by regression to the mean (RTM). They make four predictions about what patterns of data would demonstrate a genuine effect for imagination versus those that would be explainable by RTM. We review each of those predictions, and demonstrate significant problems with them. We conclude that imagination inflation is a genuine effect, and that Pezdek and Eddy’s work has contributed to the growing research showing that when people imagine fictitious events from long ago, they become more confident that those false events were genuine experiences.     

Irrelevant singletons in pop-out search: attentional capture or filtering costs?

The aim of the present study was to investigate whether costs invoked by the presence of an irrelevant singleton distractor in a visual search task are due to attentional capture by the irrelevant singleton or spatially unrelated filtering costs. Measures of spatial effects were based on distance effects, compatibility effects, and differences between singleton and nonsingleton target trials. The results show that the distractor only regularly captures attention when it is nonpredictive of the target position and unpredictably changes its features. When the distractor is antipredictive of the target position and the irrelevant features of target and distractor remain constant throughout the experiment, spatially unrelated filtering costs prevail. Further experiments showed that filtering costs accrue from distractor inhibition or target activation processes, which in turn can be modeled as instances of priming of pop-out. The present study thus clarifies the notion of filtering costs and modifies present accounts of the distraction effect. Moreover, the results also relate to research of intertrial priming by showing that priming affects the stage of attentional selection and depends on top-down attentional control settings.
