Two experiments are described in which rats received a series of shock and food presentations in a Pavlovian counterconditioning sequence. Subsequently, the capacity of the shock to act as a reinforcer during conditioned emotional response (CER) training was assessed. In the first experiment, following each shock during counterconditioning by a food presentation was found to retard the developm...
Fear-potentiated startle (FPS) is an increasingly popular psychophysiological method for the objective assessment of fear and anxiety. Studies applying this method often elicit the startle reflex with loud white-noise stimuli. Such intense stimuli may, however, alter psychological processes of interest by creating unintended emotional or attentional artifacts. Additionally, loud acoustic probes...
Are there individual differences in the tendency to enjoy tasks regardless of tasks' contents or situational determinants? To answer this question, we constructed and validated six-item Trait Task Enjoyment Scale (TTES). In Study 1, it had an internally consistent one-factor structure (pooled N = 997); good test-retest reliabilities over 1 4 months; measurement invariance regarding gender (stro...
Procrastination is a prevalent and pernicious form of self-regulatory failure that is not entirely understood. Hence, the relevant conceptual, theoretical, and empirical work is reviewed, drawing upon correlational, experimental, and qualitative findings. A meta-analysis of procrastination's possible causes and effects, based on 691 correlations, reveals that neuroticism, rebelliousness, and se...
Stressful situations, the aversiveness of events, or increases in task difficulty (e.g., conflict) have repeatedly been shown to be capable of triggering attentional control adjustments. In the present study we tested whether the particularity of an fMRI testing environment (i.e., EPI noise) might result in such increases of the cognitive control exerted. We found that participants were more ef...
A model of time-consistent procrastination is developed to assess the extent to which the observed behavior is compatible with rational behavior. When a finite work requirement must be completed by a deadline, the remaining time for leisure is an exhaustible resource. With a positive rate of time preference, the optimal allocation of this resource results in more hours spent working (and fewer ...
