Mind wandering increases linearly with text difficulty.

Although mind wandering during reading is known to be affected by text difficulty, the nature of this relationship is not yet fully understood. To examine this issue, we conducted an experiment in which participants read non-fiction texts that varied along five levels of difficulty under naturalistic conditions. Difficulty levels were determined based on Flesch-Kincaid Grade Levels and verified with Coh-Metrix indices.

Lay Theories of the Wandering Mind: Control-Related Beliefs Predict Mind Wandering Rates in- and outside the Lab.

People often fail to keep their mind from wandering. Here, we examine how the tendency to mind wander is affected by people's beliefs, or lay theories. Building on research on lay theories and self-regulation, we test whether differences in people's beliefs about the extent to which mind wandering is controllable affect thought control strategies and mind-wandering rates in daily life and the laboratory.

Rushing to Appear Virtuous: Time Pressure Increases Socially Desirable Responding.

Prosociality increases when decisions are made under time pressure. Here, we investigated whether time pressure increases socially desirable responding outside social interactions (Study 1). Finding that it did, we then examined whether this is because people align their responses with the concept of their "true" self or because of an intuitive tendency to comply with norms (Study 2).

Is perception the missing link between creativity, curiosity and schizotypy? Evidence from spontaneous eye-movements and responses to auditory oddball stimuli.

What is the relationship between creativity, curiosity, and schizotypy? Schizophrenia-spectrum conditions and creativity have been linked to deficits in filtering sensory information, and curiosity is associated with information-seeking. This raises the possibility of a perception-based link between all three concepts. Here, we investigated whether the same individual differences in perceptual encoding explain variance in creativity, curiosity, and schizotypy.

Beyond subjective judgments: Predicting evaluations of creative writing from computational linguistic features.

The question of how to evaluate creativity in the context of creative writing has been a subject of ongoing discussion. A key question is whether something as elusive as creativity can be evaluated in a systematic way that goes beyond subjective judgments. To answer this question, we tested whether human evaluations of the creativity of short stories can be predicted by: (1) established measures of creativity and (2) computerized linguistic analyses of the stories.

All for one or some for all? Evaluating informative hypotheses using multiple N = 1 studies.

Analyses are mostly executed at the population level, whereas in many applications the interest is on the individual level instead of the population level. In this paper, multiple N = 1 experiments are considered, where participants perform multiple trials with a dichotomous outcome in various conditions. Expectations with respect to the performance of participants can be translated into so-called informative hypotheses.

The Richness of Inner Experience: Relating Styles of Daydreaming to Creative Processes.

Psychologists have long hypothesized that daydreaming (i.e., engaging in stimulus-independent, task-unrelated thoughts and images) may facilitate creativity, but evidence for this hypothesis has been mixed.

Mind wandering "Ahas" versus mindful reasoning: alternative routes to creative solutions.

Based on mixed results linking both mindfulness and its opposing construct mind wandering to enhanced creativity, we predicted that the relationship between mindfulness and creativity might depend on whether creative problems are approached through analytic strategy or through "insight" (i.e., sudden awareness of a solution).

Unaware yet reliant on attention: Experience sampling reveals that mind-wandering impedes implicit learning.

Although implicit learning has been widely studied, controversy remains regarding its reliance on attentional resources. A central issue in this controversy is the question of how best to manipulate attention. The usual approach of comparing implicit learning in a serial reaction time (SRT) task under single- versus dual-task conditions is known to be problematic, because the secondary task may not only divert attention away from the primary task, but also interfere with the implicit-learning process itself.

Motivating meta-awareness of mind wandering: A way to catch the mind in flight?

Given the negative effects of mind wandering on performance, it may be profitable to be aware of task-unrelated thoughts (TUTs) as they occur. The present study investigated whether motivating people to catch TUTs increases meta-awareness. We offered incentives for increased self-catching during reading.

A new perspective on human reward research: how consciously and unconsciously perceived reward information influences performance.

The question of how human performance can be improved through rewards is a recurrent topic of interest in psychology and neuroscience. Traditional, cognitive approaches to this topic have focused solely on consciously communicated rewards. Recently, a largely neuroscience-inspired perspective has emerged to examine the potential role of conscious awareness of reward information in effective reward pursuit.

Promising high monetary rewards for future task performance increases intermediate task performance.

In everyday life contexts and work settings, monetary rewards are often contingent on future performance. Based on research showing that the anticipation of rewards causes improved task performance through enhanced task preparation, the present study tested the hypothesis that the promise of monetary rewards for future performance would not only increase future performance, but also performance on an unrewarded intermediate task. Participants performed an auditory Simon task in which they responded to two consecutive tones.

When unconscious rewards boost cognitive task performance inefficiently: the role of consciousness in integrating value and attainability information.

Research has shown that high vs. low value rewards improve cognitive task performance independent of whether they are perceived consciously or unconsciously. However, efficient performance in response to high value rewards also depends on whether or not rewards are attainable.

Boosting or choking--how conscious and unconscious reward processing modulate the active maintenance of goal-relevant information.

Two experiments examined similarities and differences in the effects of consciously and unconsciously perceived rewards on the active maintenance of goal-relevant information. Participants could gain high and low monetary rewards for performance on a word span task. The reward value was presented supraliminally (consciously visible) or subliminally at different stages during the task.
