The influence of drinking consequences on alcohol expectancy likelihoods and valences: an item-level multi-level approach.

Objective: Alcohol expectancy theory proposes that beliefs about drinking motivate or deter drinking. Although expectancies influence drinking, less is known about how the consequences of drinking influence expectancies. We modeled a feedback conceptualization of how the experience of specific consequences influenced people's beliefs about how likely a consequence will occur (i.

Negative urgency as a state-level process.

Objective: Test whether global self-reports of urgency moderated the within-person associations of affect and impulsive behaviors.

Background: Negative urgency is a personality trait that is a risk factor for a range of psychopathology. Although it is assumed that global self-reports of urgency measure individual tendencies to act more impulsively in the face of negative emotions, evidence from ecological momentary assessment studies is mixed.

Characterizing the momentary association between loneliness, depression, and social interactions: Insights from an ecological momentary assessment study.

Evidence suggests that loneliness causes people to feel more depressed. It is unknown, however, why this association occurs and whether momentary versus chronic experiences of loneliness are implicated. Theoretical accounts suggest that momentary feelings of loneliness produce two competing motivations: social reaffiliation and social withdrawal.

An experimental investigation into the effect of negative affect on the behavioral economic demand for alcohol.

Objective: It is hypothesized that alcohol use is reinforcing when used as a strategy to cope with negative affect. Although the evidence for this hypothesis in observational data is weak, some experimental evidence suggests that the behavioral economic demand for alcohol increases immediately following a negative emotional event. We hypothesized that people show a higher demand for alcohol following negative (vs.

Modeling the value-based decision to consume alcohol in response to emotional experiences.

Evidence for negative reinforcement of alcohol use is mixed; one possible explanation for this is that people make value-based decisions whether to regulate their emotions via alcohol or an alternative, and only drink-to-cope when alcohol's reinforcing value is larger than that of available alternatives. If this is the case, immediately following a negative emotional event, the value for alcohol should increase primarily in heavy drinkers, whereas in light drinkers, alternative ways of coping should be valued. We conducted a preregistered online experiment ( = 200) with a mixed design (between: heavy vs.

Exploring associations between affect and marijuana use in everyday life via specification curve analysis.

Although frequently hypothesized, the evidence for associations between affect and marijuana use in everyday life remains ambiguous. Inconsistent findings across existing work may be due, in part, to differences in study design and analytic decisions, such as study inclusion criteria, the operationalization of affect, or the timing of affect assessment. We used specification curves to assess the robustness of the evidence for affect predicting same-day marijuana use and marijuana use predicting next-day affect across several hundred models that varied in terms of decisions that reflect those typical in this literature (e.

Harmonization of theory, methods, and inferences in addictions research.

The articles in the present special section highlight four ways in which our applications of methods, and their harmonization with theory, can hold us back, and each offers an avenue for improvement that brings us closer to our goal of building a cumulative scientific record of the study of addiction. It brings together four articles that are intended to provide new ideas and directions for research on addictive behaviors. It is important for researchers to consider how their study designs, measurements, and statistical tests are specific expressions of the theories they wish to test.

No evidence for trait- and state-level urgency moderating the daily association between negative affect and subsequent alcohol use in two college samples.

It remains unclear whether the negative reinforcement pathway to problematic drinking exists, and if so, for whom. One idea that has received some support recently is that people who tend to act impulsively in response to negative emotions (i.e.

The effect of opportunity costs on mental fatigue in labor/leisure trade-offs.

Most people experience the feeling of mental fatigue on a daily basis. Previous research shows that mental fatigue impacts information processing and decision making. However, the proximal causes of mental fatigue are not yet well understood.

Fatigue, boredom and objectively measured smartphone use at work.

Nowadays, many people take short breaks with their smartphone at work. The decision whether to continue working or to take a smartphone break is a so-called labour versus leisure decision. Motivational models predict that people are more likely to switch from labour (work) to leisure (smartphone) the more fatigue or boredom they experience.

Labor/leisure decisions in their natural context: The case of the smartphone.

In this research, we attempt to understand a common real-life labor/leisure decision, i.e., to perform cognitive work or to interact with one's smartphone.

"20,000 leagues under the sea": Sleep, cognitive performance, and self-reported recovery status during a 67-day military submarine mission.

Employing a field-based monitoring paradigm, the current study examined day-to-day fluctuations in actigraphy-based sleep recordings, cognitive performance (10-min psychomotor vigilance test; PVT), and self-reported recovery status among 14 submariners throughout a 67-day military mission. Mission averages reflected suboptimal sleep that was of short overall duration (5:46 ± 1:29 h per 24-h day) and relatively low efficiency (82.5 ± 9.
