Segmentation of Worked Examples: Effects on Cognitive Load and Learning

Two ways to improve worked examples are investigated: presenting them in a segmented format (i.e., in pieces separated by blank lines) and instructing students to segment them actively (i.e., students must divide the examples in pieces). Segmented examples are expected to support learning because they show which information elements belong together. Learners might also be encouraged to think about which information elements belong together when they are instructed to actively segment, but on the negative side, this is an additional task that might impose extra cognitive load without facilitating learning. Results showed that students in the actively segmenting condition invested more effort in learning than students in the other conditions without performing better. Furthermore, studying segmented examples required less effort to achieve equal learning outcomes than studying nonsegmented ones. So, presenting learners with segmented examples improved the efficiency of the learning process, whereas instructing them to actively segment decreased this efficiency.

Body image satisfaction among Norwegian adolescents and young adults: a longitudinal study of the influence of interpersonal relationships and BMI

This study used a latent growth curve modeling approach to examine body image satisfaction in 1132 Norwegian adolescent and adult males and females measured at six times between ages 13 and 30. An additional model examined the long term influence of parent-child relationship, peer relationship (both relationships assessed at age 13), and BMI (measured at each interval) to the patterns of change. The results showed a linear growth in body image satisfaction through adolescence followed by a stabilizing of the latent curve in adulthood for both genders. There were gender and developmental variations in the relative contributions of parents and peers for the slope and quadratic growth and in the contribution of BMI to body image satisfaction. When controlling for BMI, initial parent-child relationships and peer relationship predicted the variance in slope growth for males. Parent-child relationship predicted quadratic growth for males. Among females, only initial peer relationships predicted linear growth. No effect was found for quadratic growth. BMI had an additional negative effect on body image satisfaction during adulthood.     

Rapid allocation of temporal attention in the attentional blink paradigm

How fast can information of a first target (T1) in a rapid serial visual presentation be used for top-down allocation of attention in time? A valid cue about the temporal position of a second target (T2) was integrated into T1. The data show that 100 ms after T1 onset, T2 was identified better than without cue, raising the conditional T2 performance. T1 apparently triggers a facilitative effect of attention, known from other paradigms such as peripheral cueing.     

Quantifying the Strength of General Factors in Psychopathology: A Comparison of CFA with Maximum Likelihood Estimation,BSEM, and ESEM/EFA Bifactor Approaches

Whether or not importance should be placed on an all-encompassing general factor of psychopathology (or p factor) in classifying, researching, diagnosing, and treating psychiatric disorders depends (among other issues) on the extent to which comorbidity is symptom-general rather than staying largely within the confines of narrower transdiagnostic factors such as internalizing and externalizing. In this study, we compared three methods of estimating p factor strength. We compared omega hierarchical and explained common variance calculated from confirmatory factor analysis (CFA) bifactor models with maximum likelihood (ML) estimation, from exploratory structural equation modeling/exploratory factor analysis models with a bifactor rotation, and from Bayesian structural equation modeling (BSEM) bifactor models. Our simulation results suggested that BSEM with small variance priors on secondary loadings might be the preferred option. However, CFA with ML also performed well provided secondary loadings were modeled. We provide two empirical examples of applying the three methodologies using a normative sample of youth (z-proso, n = 1,286) and a university counseling sample (n = 359).     

More Bang for the Buck?: Personality Traits as Moderators of Responsiveness to Pay-for-Performance

Extensive prior research has found that, on average, people are more productive under properly designed incentive pay systems; this effect is not necessarily uniform across people, however. In two laboratory studies utilizing within-person study designs and tasks varying in level of structure, we examine how individuals’ personality dispositions systematically predict differential responsiveness to pay-for-performance (PFP) relative to fixed pay. As expected, average productivity was higher when people received PFP (in the form of piecework pay) than when they received fixed pay, but the productivity-enhancing effects of PFP were especially pronounced for more extraverted and less conscientious individuals in less structured tasks. Emotionally stable individuals also had enhanced productivity under PFP, an effect that has not been observed in previous research on personality and pay.     

Art as Festival in Heidegger and Gadamer

In 'Art as Festival', I put Heidegger and Gadamer into dialogue concerning their respective critiques of traditional aesthetics and their more positive views on the work of art. I use the festival theme to examine some of the philosophical issues in Heidegger's and Gadamer's approaches to the work of art. Specifically, I look at the way both figures conceive the work of art as an encounter which, like the festival, involves a transcendence of subjectivity in an encounter with an event - in this case, the artwork - which the individual does not direct, but rather in which they participate. Putting the theme of festival into play also provides a useful critical lever, especially in the way that it raises important issues of community. More specifically, reflecting on the festival celebration raises questions of the nature of this community, of the relation of the community created in the festival event to the community of the everyday, and thus also of the relation of the aesthetic and the political.     

Creativity and Sex Composition: An Experimental Illustration

An experiment is reported in which the effect of sex composition on the creativity of brainstorming groups is investigated. It was hypothesized that mixed sex groups would be more creative than either homogeneous male or homogeneous female groups. Fifteen groups, consisting of four members each two males and two females; four females; four males, took part in the experiment. The experimenter noted the number of ideas generated per person, as well as the different associations with these ideas, and the number of different angles from which the task was approached. After finishing the exercise, subjects completed a post-experimental questionnaire. Results show that heterogeneous groups produced more creative outcomes than homogeneous groups. Also, they rated their process more positively. These findings are discussed in relation to the type of task used, and in relation to the general notion that heterogeneous groups are likely to produce more creative outcomes yet suffer from more process problems as compared to homogeneous groups.     

Relationship between family religious behaviors and child well-being among third-grade children

While there is growing empirical evidence that religion can have a positive impact on the health and well-being of adults and adolescents, less is known about its influence on the welfare of children. The current paper examined the relative importance of family religiosity and religious behaviors on multiple measures of children's well-being (general health, academic achievement, social skills, and behavior problems) and sought to identify whether religious variables contribute above and beyond non-religious measures of family caregiving. Parent use of religious coping and family religious behaviors, the latter defined as attendance at religious or spiritual programs, predicted several aspects of child well-being above and beyond parenting styles. Parental religious coping significantly predicted child social skills and externalizing behaviors above and beyond parenting styles. Family religious service attendance significantly predicted child health and social skills, and inversely predicted internalizing behaviors, above and beyond both parenting styles and parent use of religious coping.     

“It can save you if you just forget”: Closeness and Competence as Conditions for Coping among Ugandan Orphans

This article explores the coping strategies of orphaned children and their caregivers supported by a community-based organization in a Ugandan slum area. In-depth qualitative interviews were conducted with eight orphans (aged 12 to 16 years) and their caregivers selected by the community-based organization. The children had experienced several co-occurring risk factors such as loss and separation, poverty, disease, and an unsafe environment. Most caregivers were extended family members. One caregiver was an unrelated foster carer. Three of the households were child-headed. Data were analysed using an adapted approach of Giorgio's (Hafting, 1995; Malterud, 2001) psychological-phenomenological method. Participating children from child-headed households lacked protective factors associated with closeness (i.e., supportive dyadic relationships). All the children in the study experienced competence in the arenas of school and household chores. Cultural advice on handling adversity, including ‘forgetting’, ‘accepting’ and ‘adjusting’, appears to contradict Western theories of coping. Sommerschild's theoretical model on the conditions for coping was effective in identifying conditions in children's lives that may impair their coping, self-worth, and resilience.     

Using segmentation to support the learning from animated soccer scenes: An effect of prior knowledge

ObjectivesWe used a cognitive load perspective to investigate the effects of levels of learner expertise and different forms of segmentation in learning from animated soccer scenes.MethodExpert and novice players (N = 48) completed a recall reconstruction-test and rated their invested mental effort after studying a continuous animation, a macro-step and a micro-step segmented animation.ResultsFindings demonstrated an expertise reversal effect for segmentation. It positively affected learning outcomes of novices but not experts (even though they still invested less mental effort and repeated the animation less often in the two segmented conditions). Additionally, novices benefited more from micro-step segmentation than from macro-step segmentation, while experts performed at the same level with both forms of segmentation.ConclusionsStudy results suggested that adapting instructional animation formats to players with different levels of expertise should be a crucial part of successful training.
