How green defaults promote environmentally friendly decisions: Attitude‐conditional default acceptance but attitude‐unconditional effects on actual choices

Defaults (i.e., options that become effective without an active choice) have been found to be powerful tools to influence decision‐making in a range of behavioral domains. However, seemingly conflicting assumptions have been expressed regarding the interplay of defaults with individual attitudes. Whereas some expect attitude‐conditional effects (i.e., a statistical default‐by‐attitude interaction), others assume an attitude‐unconditional effectiveness of defaults (i.e., statistically additive effects). Integrating both assumptions, we argue that the interplay of defaults and attitudes depends on what is considered a default effect. Specifically, whereas default acceptance is likely to be attitude‐conditional, we predicted that defaults and attitudes would add up in explaining people's actual choices. We tested these hypotheses in an online shopping scenario presenting environmentally friendly or conventional default products to 231 participants. Participants’ environmental attitude was assessed with the General Ecological Behavior scale and actual product choices were identified if participants rejected a given default product. In line with our hypotheses, default acceptance was predicted by a default‐by‐attitude interaction. In contrast, actual environmentally friendly product choices were found to be an additive function of defaults and participants’ environmental attitude. From an applied perspective, our findings suggest that defaults can readily be applied even in attitude‐heterogeneous target populations. Concurrently, however, our findings also speak of the importance of people's attitudes for understanding individual decision‐making.     

The contagious impact of playing violent video games on aggression: Longitudinal evidence

Meta-analyses have shown that violent video game play increases aggression in the player. The present research suggests that violent video game play also affects individuals with whom the player is connected. A longitudinal study (N = 980) asked participants to report on their amount of violent video game play and level of aggression as well as how they perceive their friends and examined the association between the participant's aggression and their friends’ amount of violent video game play. As hypothesized, friends’ amount of violent video game play at Time 1 was associated with the participant's aggression at Time 2 even when controlling for the impact of the participant's aggression at Time 1. Mediation analyses showed that friends’ aggression at Time 1 accounted for the impact of friends’ amount of violent video game play at Time 1 on the participant's aggression at Time 2. These findings suggest that increased aggression in video game players has an impact on the player's social network.     

Sex differences in facial emotion perception ability across the lifespan

Perception of emotion in the face is a key component of human social cognition and is considered vital for many domains of life; however, little is known about how this ability differs across the lifespan for men and women. We addressed this question with a large community sample (N?=?100,257) of persons ranging from younger than 15 to older than 60 years of age. Participants were viewers of the television show “Tout le Monde Joue”, and the task was presented on television, with participants responding via their mobile devices. Applying latent variable modeling, and establishing measurement invariance between males and females and across age, we found that, for both males and females, emotion perception abilities peak between the ages of 15 and 30, with poorer performance by younger adults and declining performance after the age of 30. In addition, we show a consistent advantage by females across the lifespan, which decreases in magnitude with increasing age. This large scale study with a wide range of people and testing environments suggests these effects are largely robust. Implications are discussed.     

Using Dynamic Panel Models to Study Age‐related Differences and Time‐related Changes in Personality

Along with an increasing interest in the plasticity and role of personality across the adult lifespan comes the need for a diverse set of innovative statistical approaches to study it. With this paper, we set out to illustrate some of the possibilities and challenges in modelling age‐related differences and time‐related changes in personality psychology by means of dynamic panel models. To this end, we first distinguish between the study of age‐related differences and time‐related changes and demonstrate how the treatment of age and time as either discrete or continuous variables implies important modelling choices. Second, we present a selection of four example cases that address the topic of age moderation in diverse matters and with different objectives. Based on our cross‐tabulation of age and time as discrete and continuous variables, the first two example cases represent fairly well‐established models (cases A and B), whereas the remaining cases are used to illustrate current developments in the field (cases C and D). We close the paper with some final remarks on current limitation and future research directions. © 2019 European Association of Personality Psychology     

John Webster on Dogmatics and Ethics

From his earliest published writing Webster identified the moral life as the horizon of dogmatic enquiry, and his last‐published work offers a subtle clarification of how dogmatics relates to ethics. The principle ‘action follows being’ governs both the relation of the two sub‐disciplines and the internal logic of each. As theology is a knowledge acquired not only speculatively but also practically, dogmatics must look forward and practical theology look back. Their interaction covers the whole range of theological topics. It is a fittingly Chalcedonian conception stressing the duality of dogmatics and ethics alongside their unity. While specialized dogmatics and ethics are legitimate, the two remain proximate, in a definite order of origin and derivation. The temptation of a de‐moralized theology equalled by that of a theology wrongly constructed on a moral a priori. In his late essays Webster presents worked examples of how dogmatics may handle moral questions without venturing into casuistic exploration of dilemmas. One essay, however, goes further, troublingly describing ‘mortification and vivification’ as the primary human acts of the regenerate state, a function that the tradition has always assigned to love.     

Preserved re-experience of discrete emotions: Amnesia and executive function

Amnesic patients can re-experience emotions elicited by forgotten events, suggesting that brain systems for episodic and emotional memory are independent. However, the range of such emotional memories remains under-investigated (most studies employing just positive–negative emotion dyads), and executive function may also play a role in the re-experience of emotions. This is the first investigation of the intensity of the emotional re-experience of a range of discrete emotions (anger, fear, sadness, and happiness) for a group of amnesic patients. Twenty Korsakoff syndrome (KS) patients and 20 neurologically normal controls listened to four novel emotional vignettes selectively eliciting the four basic emotions. Emotional experience was measured using pen-and-paper Visual Analogue Mood Scales and episodic memory using verbal recollections. After 30 min, the recollection of stories was severely impaired for the patient group, but the emotional re-experience was no different from that of controls. Notably, there was no relationship between episodic recall and the intensity of the four emotions, such that even profoundly amnesic patients reported moderate levels of the target emotion. Exploratory analyses revealed negative correlations between the intensity of basic emotions and executive functions (e.g., cognitive flexibility and response inhibition) for controls but not patients. The results suggest that discrete emotions can be re-experienced independently of episodic memory, and that the re-experience of certain discrete emotions appears to be dampened by executive control. KS patients with absent or mild cognitive symptoms should benefit from emotion-regulation interventions aimed at reducing the recognized affective burden associated with their episodic memory deficit.     

Information structuring improves recall of emergency discharge information: a randomized clinical trial

This article examines the extent to which structuring Emergency Department discharge information improves the ability to recall that information, and whether such benefits interact with relevant prior knowledge. Using three samples of students with different levels of prior medical knowledge, we investigated the amount of information recalled after structured vs. non-structured presentation of information. Across all student samples, the structured discharge information led to a relative increase in recalled items of 17% compared to non-structured discharge information (M = 9.70, SD = 4.96 vs. M = 8.31, SD = 4.93). In the sample with least medical knowledge, however, the structured discharge information resulted in a relative increase in recall by 42% (M = 8.12 vs. M = 5.71). These results suggest that structuring discharge information can be a useful tool to improve recall of information and is likely to be most beneficial for patient populations with lower levels of medical knowledge.     

Brain responses reveal that infants' face discrimination is guided by statistical learning from distributional information

Infants' perception of faces becomes attuned to the environment during the first year of life. However, the mechanisms that underpin perceptual narrowing for faces are only poorly understood. Considering the developmental similarities seen in perceptual narrowing for faces and speech and the role that statistical learning has been shown to play for speech, the current study examined whether and how learning from distributional information impacts face identity discrimination. We familiarized 6.5‐month‐old infants with exemplars of female faces taken from a morphed continuum going from one identity to another. Using event‐related brain potentials (ERPs), we show that only infants who were familiarized with a bimodal frequency distribution, but not infants familiarized with a unimodal frequency distribution, discriminated between identities. These results are the first to demonstrate the influence of probabilistic information on infants' face identity discrimination, suggesting that statistical learning contributes to perceptual attunement for both faces and language.     

Digital Stress over the Life Span: The Effects of Communication Load and Internet Multitasking on Perceived Stress and Psychological Health Impairments in a German Probability Sample

The present study investigated the psychological health effects and motivational origins of digital stress based on a representative survey of 1,557 German Internet users between 14 and 85 years of age. Communication load resulting from private e-mails and social media messages as well as Internet multitasking were positively related to perceived stress and had significant indirect effects on burnout, depression, and anxiety. Perceived social pressure and the fear of missing out on information and social interaction were key drivers of communication load and Internet multitasking. Age significantly moderated the health effects of digital stress as well as the motivational drivers of communication load and Internet multitasking. The results, thus, underline the need to address digital stress from a life span perspective.     

Disagreements Over Analogies

This essay presents a dialogical framework for treating philosophical disagreements as persuasion dialogues with analogical argumentation, with the aim of recasting philosophical disputes as disagreements over analogies. This has two benefits: (1) it allows us to temporarily bypass conflicting metaphysical intuitions by focusing on paradigmatic examples, (dis)similarities, and the plausibility of conclusions for or against a given point of view; and (2) it can reveal new avenues of argumentation regarding a given issue. This approach to philosophical disagreements is illustrated by studying the role of argumentation by analogy in disputes over Lockean justifications of intellectual property rights, and disagreements over whether artificial agents should be treated as moral agents. Finally, a nonexhaustive list of possible global and local points of contention over analogical arguments is identified in order to highlight potential avenues of argumentation in disagreements over analogies.
