Contributions of beliefs and processing fluency to the effect of relatedness on judgments of learning

Discovering how people judge their memories has been a major issue for metacognitive research for over 4 decades; many factors have been discovered that affect people’s judgments, but exactly how those effects are mediated is poorly understood. For instance, the effect of word pair relatedness on judgments of learning (JOLs) has been repeatedly demonstrated, yet the underlying basis of this substantial effect is currently unknown. Thus, in three experiments, we assessed the contribution of beliefs and processing fluency. In Experiment 1, participants studied related and unrelated word pairs and made either prestudy JOLs or immediate JOLs. Participants gave higher estimates for related than for unrelated pairs, suggesting that participants’ beliefs at least partially drive the relatedness effect on JOLs. Next, we evaluated the contribution of processing fluency to the relatedness effect either (1) by disrupting fluency by presenting half the pairs in an aLtErNaTiNg format (Experiment 2) or (2) by measuring how fluently participants processed pairs at study and statistically estimating the degree to which conceptual fluency mediated the effects of relatedness on JOLs (Experiment 3). Results from both experiments indicated that fluency contributes minimally to the relatedness effect. Taken together, these results indicate that people’s beliefs about how relatedness influences memory are responsible for mediating the relationship between relatedness and JOLs. In general, empirically establishing what mediates the effects of other factors on people’s judgments remains a major agenda for advancing theory of metacognitive monitoring.     

A Meta‐Analytic Structural Model of Dispositonal Affectivity and Emotional Labor

The exponential growth of the service economy has increased the attention that organizational researchers have paid to the concept of emotional labor. Although much progress has been made in the field, few studies have provided an integrated picture of how individual dispositions, perceived display rules, and emotional labor behaviors shape employee outcomes. To clarify and compare results across this growing body of literature, a quantitative review was developed, along with a theoretically derived path diagram of key emotional labor constructs. Evidence from our structural meta‐analytic model based on 116 primary studies demonstrates that examining affective dispositions and emotional labor constructs and the pattern of positive and negative results helps to clarify and add specificity to the literature. Results were consistent with the perspective that surface acting emotion regulation strategies have a pattern of negative relationships with work outcomes of job satisfaction and stress/exhaustion (but not with job performance), whereas deep acting emotion regulation strategies have a pattern of positive relationships with all of these work outcomes.     

A Survey of the Sources of Noise in fMRI

Functional magnetic resonance imaging (fMRI) is a noninvasive method for measuring brain function by correlating temporal changes in local cerebral blood oxygenation with behavioral measures. fMRI is used to study individuals at single time points, across multiple time points (with or without intervention), as well as to examine the variation of brain function across normal and ill populations. fMRI may be collected at multiple sites and then pooled into a single analysis. This paper describes how fMRI data is analyzed at each of these levels and describes the noise sources introduced at each level.     

Barriers to Treatment in an Ethnically Diverse Sample of Families Enrolled in a Community-Based Domestic Violence Intervention

Using quantitative and qualitative data, we examined the association between barriers to treatment, motivating factors, treatment attendance, and outcome in a sample of 63 mothers (most of Asian or Pacific Islander descent) enrolled in a family-based domestic violence treatment program. A high number of perceived barriers was associated with lower attendance and lower scores on assessment of parenting practices at posttreatment. Mothers reported relying on their own motivation, observations of children's improvement, and the quality of their relationships with staff and group members to overcome barriers. A larger number of motivating factors was associated with positive parenting practices at posttreatment. Discussion includes the benefits of a mixed-method approach to measuring barriers and its clinical application to increase treatment participation.     

Executive-process interactive control: A unified computational theory for answering 20 questions (and more) about cognitive ageing

Although the effects of ageing on human information processing and performance have been studied extensively, many fundamental questions about cognitive ageing remain to be answered definitively. For example, what are the sources of age-related slowing? How much is working-memory capacity reduced in older adults? Is time-sharing ability lost with age? Answering such questions requires a unified computational theory that characterises the interactive operations of many component mental processes and integrates diverse data on cognitive ageing. Toward fulfilling this requirement, an executive-process interactive control (EPIC) architecture has been extended to model performance of both young and older adults. EPIC models yield accurate accounts of ageing effects on reaction times and accuracy in basic dual-task and working-memory paradigms. From these accounts, it appears that time-sharing ability and working-memory capacity decrease relatively little until after 70 years of age. Before age 70, at least some apparent performance decrements may be attributable to conservative executive processes and inefficient task procedures rather than decreased "hardware" functionality. By clarifying and deepening such insights, unified computational theories like EPIC will help answer many questions about cognitive ageing.     

Descartes and the Labyrinth of the World

In the Rules the young Descartes likens his method to the thread that guided Theseus. The simile is born of a confidence that he has seen through the art of the followers of Daedalus and this has given him a model of how to unriddle the labyrinth of the world. From the very beginning Descartes had an interest not only in optics, perspective, and painting, but in using his knowledge of them to duplicate some of the effects said to have been created by the thaumaturgic magicians. Anamorphoses and automata not only provided Descartes with examples of deceptive appearance, but also pointed the way to the solution of the riddle they posed. Yet it is precisely the attempt to take this exit from the labyrinth of the world that threatens to lead back into it, as the search for truth is threatened by the infinity of space. To claim absolute truth, the natural philosopher would have to show that the mechanical model he has proposed is the only one that could account for the phenomena in question. This, as Descartes himself is forced to recognize, he is unable to do. Are we back in the labyrinth? Instead of seeing in Descartes's method an Ariadne's thread, Father Bourdin likens that method to Icarus. Annoyed, Descartes ridicules the good Father. But Bourdin's too often empty rhetoric raises a serious question: is Descartes Theseus, Daedalus, or Icarus? At stake is our understanding of the world we live in.     

Knowledge junkies or careerbuilders? A mixed-methods approach to exploring the determinants of students' intention to earn a PhD

What are the determinants of students' interest in earning a PhD? In this study, we use a mixed-methods approach to pursue this question. Based on qualitative interview data, we develop a model in which academic motivation and academic achievement interact with contextual factors such as working conditions to influence career intentions. We then test this model using a sample of 229 students currently enrolled in master-level courses of study at a German university. Our results speak to the role of intrinsic versus extrinsic motivations in the context of PhD intentions. In contrast to our expectations, results suggest that while intrinsic life aspirations and the intellectual challenge of gaining a PhD play a significant role for students' intention to pursue a PhD, extrinsic life aspirations and contextual determinants seem to be less influential. Furthermore, results highlight the importance of gaining familiarity and experience with academic work for students' career decisions.     

Review and Discussion of Strategies to Address Low Trainer‐to‐Staff Ratios

Researchers have developed an array of highly adaptable intervention packages with well‐documented efficacy for staff and teacher training. As indicated by Parsons, Rollyson, and Reid (2012) in their article on best practices in staff training, behavior analysts must use methods that are both effective and efficient given the limited resources of many human service settings (e.g., low trainer‐to‐staff ratios). The purpose of this paper is to summarize research on practical innovations for staff and teacher training, including the use of video‐based technology and self‐instruction materials that may help trainers to operate effectively despite limited time and personnel. Results are discussed in terms of the current state of the evidence for each practical innovation and considerations for integrating these strategies with best practices in staff training.

Nonnaïveté among Amazon Mechanical Turk workers: Consequences and solutions for behavioral researchers

Crowdsourcing services—particularly Amazon Mechanical Turk—have made it easy for behavioral scientists to recruit research participants. However, researchers have overlooked crucial differences between crowdsourcing and traditional recruitment methods that provide unique opportunities and challenges. We show that crowdsourced workers are likely to participate across multiple related experiments and that researchers are overzealous in the exclusion of research participants. We describe how both of these problems can be avoided using advanced interface features that also allow prescreening and longitudinal data collection. Using these techniques can minimize the effects of previously ignored drawbacks and expand the scope of crowdsourcing as a tool for psychological research.
