Why does placing the question before an arithmetic word problem improve performance. A situation model account.
2007
The aim of this paper is to investigate the controversial issue of the nature of the representation constructed by individuals to solve arithmetic word problems. More precisely, we consider the relevance of two different theories: the situation or mental model theory (Johnson-Laird, 1983; Reusser, 1989) and the schema theory (Kintsch & Greeno, 1985; Riley, Greeno, & Heller, 1983). Fourth-graders who differed in their mathematical skills were presented with problems that varied in difficulty and with the question either before or after the text. We obtained the classic effect of the position of the question, with better performance when the question was presented prior to the text. …
Harder, Better, Faster, Stronger? The Relationship between Cognitive Task Demands in Video Games and Recovery Experiences
2019
Research has repeatedly demonstrated that the use of interactive media is associated with recovery experiences, suggesting that engaging with media can help people to alleviate stress and restore mental and physical resources. Video games, in particular, have been shown to fulfil various aspects of recovery, not least due to their ability to elicit feelings of mastery and control. However, little is known about the role of cognitive task demand (i.e., the amount of cognitive effort a task requires) in that process. Toward this end, our study aimed to investigate how cognitive task demand during gameplay affects users’ recovery experiences. Results of a laboratory experiment suggest that dif…
Elektronische Tagebücher optimieren die Kognitive Verhaltenstherapie bei Krankheitsängsten : eine randomisiert-kontrollierte Studie
2015
Zentrale Komponenten in kognitiv-behavioralen Erklärungsmodellen der Hypochondrie und den daraus abgeleiteten Behandlungen sind eine selektive Aufmerksamkeitslenkung auf körperliche Empfindungen und ein katastrophisierender Symptominterpretationsbias. Wir untersuchten, ob sich die Effektivität einer störungsspezifischen Kognitiven Verhaltenstherapie (KVT) für Patienten mit Hypochondrie durch ein zusätzliches zweiwöchiges elektronisches Tagebuchtraining (TBT), das auf eine Korrektur der Symptominterpretationen abzielt, verbessern lässt. Zu diesem Zweck wurden 35 Patienten mit Hypochondrie randomisiert zwei Interventionsformen zugewiesen: Gruppe 1 (N = 16) erhielt vor der KVT (16 Einzelsitzu…
Does the Relation between Rapid Automatized Naming and Reading Depend on Age or on Reading Level? A Behavioral and ERP Study
2018
Reading predictors evolve through age: phonological awareness is the best predictor of reading abilities at the beginning of reading acquisition while Rapid Automatized Naming (RAN) becomes the best reading predictor in more experienced readers (around 9–10 years old). Those developmental changes in the relationship between RAN and reading have so far been explained in term of participants' age. However, it should be noted that in the previous experiments age always co-vary with participants reading level. It is thus not clear whether RAN-reading relationship is developmental in nature or related to the reading system itself. This study investigates whether the behavioral changes in the rel…
Misguided Effort with Elusive Implications
2016
Good self-control has been linked to adaptive outcomes such as better health, cohesive personal relationships, success in the workplace and at school, and less susceptibility to crime and addictions. In contrast, self-control failure is linked to maladaptive outcomes. Understanding the mechanisms by which self-control predicts behavior may assist in promoting better regulation and outcomes. A popular approach to understanding self-control is the strength or resource depletion model. Self-control is conceptualized as a limited resource that becomes depleted after a period of exertion resulting in self-control failure. The model has typically been tested using a sequential-task experimental p…
Habitual initiation of media use and a response-frequency measure for its examination
2014
When measuring media habits, most scholars rely on retrospective self-reports about behavioral frequency, context stability, or automaticity of the performance. This article develops a new implicit measurement for media research to complement existing approaches, which focuses on measuring the initiation of general, goal-related habits. In the response-frequency measure of media habit (RFMMH), participants are presented with several media use goals and are asked to choose quickly and without deliberation which media device (television set, radio set, newspaper, computer, mobile device) they would use. The more often a media device is chosen, the stronger the mental script to choose this dev…
Internalization of conflict and attitude change
1995
In a 2 × 2 × 2 design, eighty smokers were exposed to an anti-smoking appeal attributed either to an expert source (superior status) or a minority source (inferior status). Subjects were either allowed or not to smoke during the experiment. In addition subjects had to memorize part of the appeal and a recall task either followed after reading the appeal (completed task) or not (uncompleted task). The results show that the expert source produces more attitude change than the minority when the tension induced by the source is weakened (either by the opportunity to smoke or task completion). In contrast the minority has more impact when subjects are not able to smoke or when the task is not co…

Children born of War and Social Trust - Analyzing Consequences of Rejection
2017
AbstractThis article examines the question whether rejection experiences negatively relate to the social trust of Children Born of War (CBOW) and if this connection is mediated by sense of self-worth. CBOW is a group of people born out of relations during war- and post-war times, involving one parent being a foreign soldier, a para-military officer, rebel or other person directly participating in the hostilities, while the other parent is a member of the native population. Also children born to child soldiers and children fathered by members of a peacekeeping troop are included within this group. These children, due to their biological background, often grow up in a surrounding in which the…
Efficacy and cost-effectiveness of guided and unguided internet- and mobile-based indicated transdiagnostic prevention of depression and anxiety (ICa…
2019
Background Depression and anxiety are highly prevalent and often co-occur. Several studies indicate the potential of disorder-specific psychological interventions for the prevention of each of these disorders. To treat comorbidity, transdiagnostic treatment concepts seem to be a promising approach, however, evidence for transdiagnostic concepts of prevention remains inconclusive. Internet- and mobile-based interventions (IMIs) may be an effective means to deliver psychological interventions on a large scale for the prevention of common mental disorders (CMDs) such as depression and anxiety. IMIs have been shown to be effective in treating CMDs, e.g. in reducing symptoms of depression and an…
