The application of supervised machine learning to predict group- and individual-level lapse risk in smokers attempting to stop with a popular smartphone app: An exploratory study
No full textIn this exploratory study, we will use supervised machine learning algorithms (e.g. Random Forest, Support Vector Machine) to predict group- and individual-level lapse risk in smokers attempting to stop with a popular smartphone app
Violent Threat and Incumbent Support
No full textThis study uses a survey experiment to examine whether violent threat triggers favorable orientations toward the incumbent party. Subjects are drawn from the adult population of India, and threat emanates either from China or from a terrorist attack
Investigating predictions of the iCodes model in the context of the coach’s eye
No full textThe coach’s eye is defined as a “coach’s process of assessing and evaluating players, resulting in a decision to select or deselect the athlete” (Lath et al., under review) in talent selections. However, knowledge about underlying mechanisms of the coach’s eye is limited. In this study these underlying mechanisms are conceptualized using a model from decision-making research as the (de-)selection of certain athletes corresponds to a decision for one option out of many different options. The integrated coherence-based decision and search (iCodes) model states unique predictions for the information search process of decision making. The aim of this study is to investigate whether underlying mechanisms of the coach’s eye can be explained by the iCodes model. Therefore, the two core predictions of the iCodes model will be tested in the context of the coach’s eye (Lath et al, under review)
Task cue influences on priming: Manipulations of task set dominance. Words “rund” / “belebt” and symbols “§§§§§” / “$” as task cues.
No full textParticipants will perform two trial types in randomized, intermixed order: induction task trials and task-cue only trials. In induction task trials, they have to perform a semantic or perceptual decision on pictures according to a task cue (indicating the semantic or the perceptual decision). In task-cue only trials the task cues are presented without following picture, i.e. no decision has to be made. In both trial types, a masked primed lexical decision task (LDT) follows. Previous work showed that task sets (i.e. semantic or perceptual task set) are also activated if no task has to performed, i.e. they are also activated in task-cue only trials. However, the effect of task cues on masked semantic priming depended on task set dominance, i.e. the relation between elements of task cues and the decision categories. Task sets are considered as strong, when task cues and decision categories are congruent. Task sets are considered as weak due to an incongruence between task cues and decision categories. Previous research indicated that strong task sets are readily inhibited after task cue presentation, whereas weak task sets showed more persistent activation. The focus of this research therefore rests on properties of the task cues in task-cue only trials and their influence on task set activation and inhibition. We manipulate congruence of task cues and decision categories by manipulating the relation of task cue and decision category. In the strong condition, the decision categories themselves are used as task cues (“rund”, engl. round; indicates the perceptual decision; “belebt”, engl. living, indicates the semantic decision). In the weak condition, the arbitrary symbols “§§§§§” and “$” are used as task cues, counter-balanced across participants for the perceptual and semantic decision. As a consequence, there is no relation between task cues and the related decision category in the weak condition
Qualitative study on housework routines – Survey 1
No full textOur study explores how people identify, negotiate, and keep track of their housework routines. This is the preregistration for survey 1
Praise for incurring costs on others’ behalf
No full textIn this experiment we aim to test the hypothesis that praiseworthiness is influenced by the costs that one person incurs to help another. We will show participants cases in a grid world where someone picked up a coffee for their coworker on their way to work. We predict that how much a coworker is praised for picking up a coffee depends on the additional cost that the coworker incurred compared to going straight to the office
