Gamification as an approach to improve resilience and reduce attrition in mobile mental health interventions: A randomized controlled trial.

Forty percent of all general-practitioner appointments are related to mental illness, although less than 35% of individuals have access to therapy and psychological care, indicating a pressing need for accessible and affordable therapy tools. The ubiquity of smartphones offers a delivery platform for such tools. Previous research suggests that gamification-turning intervention content into a game format-could increase engagement with prevention and early-stage mobile interventions.

A preregistered multi-lab replication of Maier et al. (2014, Exp. 4) testing retroactive avoidance.

The term "retroactive avoidance" refers to a special class of effects of future stimulus presentations on past behavioral responses. Specifically, it refers to the anticipatory avoidance of aversive stimuli that were unpredictable through random selection after the response. This phenomenon is supposed to challenge the common view of the arrow of time and the direction of causality.

The Influence of Decisional and Emotional Forgiveness on Attributions.

Research on forgiveness suggests that forgiveness is an emotion-focused coping process important for clinical settings as it can promote both physical and mental health (Worthington et al., 2005; Witvliet and McCullough, 2007). Investigating antecedents of forgiveness, empirical studies and theoretical models propose that attributions influence forgiveness.

Intentional Observer Effects on Quantum Randomness: A Bayesian Analysis Reveals Evidence Against Micro-Psychokinesis.

Intentional effects of human observation on the output of quantum-based random number generators (tRNG) have been studied for decades now. This research has been known as micro-psychokinesis (micro-PK) and many studies in the field reported evidence for mentally induced non-random deviations from chance. A most recent meta-analysis from Bösch et al.

Not always a matter of context: direct effects of red on arousal but context-dependent moderations on valence.

The arousal theory of color proposes that red is associated with arousal. Research on the color-in-context theory, in turn, states that the context in which red is perceived influences its valence-related meaning and behavioral responses to it. This study faces and integrates these theories by examining the influence of red on both arousal and valence perceptions of test-relevant and neutral stimuli, rendering a color 2 (red vs.

An International Consensus Definition of the Wish to Hasten Death and Its Related Factors.

Background: The desire for hastened death or wish to hasten death (WTHD) that is experienced by some patients with advanced illness is a complex phenomenon for which no widely accepted definition exists. This lack of a common conceptualization hinders understanding and cooperation between clinicians and researchers. The aim of this study was to develop an internationally agreed definition of the WTHD.

A macroscopic violation of no-signaling in time inequalities? How to test temporal entanglement with behavioral observables.

In this paper we applied for the first time the no-signaling in time (NSIT) formalism discussed by Kofler and Brukner (2013) to investigate temporal entanglement between binary human behavioral unconscious choices at t1 with binary random outcomes at t2. NSIT consists of a set of inequalities and represents mathematical conditions for macro-realism which require only two measurements in time. The analyses of three independent experiments show a strong violation of NSIT in two out of three of them, suggesting the hypothesis of a quantum-like temporal entanglement between human choices at t1 with binary random outcomes at t2.

Forgive and Forget: Differences between Decisional and Emotional Forgiveness.

To forgive and forget is a well-known idiom, which has rarely been looked at empirically. In the current experiment, we investigated differences between emotional and decisional forgiveness on forgetting. The present study provides the first empirical support that emotional forgiveness has a strong influence on subsequent incidental forgetting.

Red - take a closer look.

Color research has shown that red is associated with avoidance of threat (e.g., failure) or approach of reward (e.

Physical and psychological factors and the wish to hasten death in advanced cancer patients.

Background: Qualitative research suggests that the wish to hasten death (WTHD) in the advanced stages of disease is mainly related to overall suffering. This quantitative study explores the relationship between the WTHD and psychological and physical factors, including survival, in patients with advanced cancer.

Methods: Cross-sectional study of 101 advanced cancer patients admitted to an acute Palliative Care Unit (PCU) and followed-up for survival.

Morals matter in economic games.

Contrary to predictions from Expected Utility Theory and Game Theory, when making economic decisions in interpersonal situations, people take the interest of others into account and express various forms of solidarity, even in one-shot interactions with anonymous strangers. Research in other-regarding behavior is dominated by behavioral economical and evolutionary biological approaches. Psychological theory building, which addresses mental processes underlying other-regarding behavior, is rare.

Color psychology: effects of perceiving color on psychological functioning in humans.

Color is a ubiquitous perceptual stimulus that is often considered in terms of aesthetics. Here we review theoretical and empirical work that looks beyond color aesthetics to the link between color and psychological functioning in humans. We begin by setting a historical context for research in this area, particularly highlighting methodological issues that hampered earlier empirical work.

The red-attractiveness effect, applying the Ioannidis and Trikalinos (2007b) test, and the broader scientific context: a reply to Francis (2013).

Francis (2013) tested for and found evidence of publication bias in 1 of the 3 focal relations examined in Elliot et al. (2010), that between red and attractiveness. He then called into question the research as a whole and the field of experimental psychology more generally.

Color in context: psychological context moderates the influence of red on approach- and avoidance-motivated behavior.

Background: A basic premise of the recently proffered color-in-context model is that the influence of color on psychological functioning varies as a function of the psychological context in which color is perceived. Some research has examined the appetitive and aversive implications of viewing the color red in romance- and achievement-relevant contexts, respectively, but in all existing empirical work approach and avoidance behavior has been studied in separate tasks and separate experiments. Research is needed to directly test whether red influences the same behavior differently depending entirely on psychological context.

Fertile green: green facilitates creative performance.

The present research sought to extend the nascent literature on color and psychological functioning by examining whether perception of the color green facilitates creativity. In four experiments, we demonstrated that a brief glimpse of green prior to a creativity task enhances creative performance. This green effect was observed using both achromatic (white, gray) and chromatic (red, blue) contrast colors that were carefully matched on nonhue properties, and using both picture-based and word-based assessments of creativity.

Red, rank, and romance in women viewing men.

In many nonhuman species of vertebrates, females are attracted to red on male conspecifics. Red is also a signal of male status in many nonhuman vertebrate species, and females show a mating preference for high-status males. These red-attraction and red-status links have been found even when red is displayed on males artificially.

Basic hue-meaning associations.

Color may not only be pleasing to the eye, but may also carry important associations relevant for psychological functioning. Two experiments were conducted to test for basic hue-meaning associations, controlling for lightness and chroma. Specifically, we used a reaction time paradigm to test for links between red and green, and words that varied in achievement content (failure and success) or valence more generally.

Context specificity of implicit preferences: the case of human preference for red.

Three experiments were conducted on color preference using a spontaneous selection paradigm with infant participants. Experiment 1 demonstrated that participants prefer red over green in a friendly laboratory environment. Experiment 2 demonstrated that participants' preference for red varies with the context in which the color is presented: Red is preferred in a hospitable context (following a happy face), but not in a hostile context (following an angry face).

Effects of mood on the speed of conscious perception: behavioural and electrophysiological evidence.

When a visual stimulus is quickly followed in time by a second visual stimulus, we are normally unable to perceive it consciously. This study examined how affective states influence this temporal limit of conscious perception. Using a masked visual perception task, we found that the temporal threshold for access to consciousness is decreased in negative mood and increased in positive mood.

The effect of red on avoidance behavior in achievement contexts.

This research tests whether the perception of red in an achievement context evokes avoidance behavior without conscious awareness and also examines the context specificity of the hypothesized red effect. In Experiment 1, participants were briefly shown red or green on the cover of an analogies test that they would ostensibly take (an achievement context) or rate on likability of (a nonachievement context) in an adjacent lab. Those shown red, relative to those shown green, knocked fewer times on the door of the adjacent lab in the achievement context; no red-green difference in knocking was observed in the nonachievement context.

Mediation of the negative effect of red on intellectual performance.

This research examines the hypothesis that an attentional process grounded in avoidance motivation-local relative to global processing-mediates the negative effect of red on intellectual performance. This hypothesis was tested in a series of experiments using two approaches to documenting mediation. Experiment 1 established that the perception of red undermines IQ test performance.

Color and psychological functioning: the effect of red on performance attainment.

This research focuses on the relation between color and psychological functioning, specifically, that between red and performance attainment. Red is hypothesized to impair performance on achievement tasks, because red is associated with the danger of failure in achievement contexts and evokes avoidance motivation. Four experiments demonstrate that the brief perception of red prior to an important test (e.

Human attachment security is mediated by the amygdala: evidence from combined fMRI and psychophysiological measures.

The neural basis of human attachment security remains unexamined. Using event-related functional magnetic resonance imaging (fMRI) and simultaneous recordings of skin conductance levels, we measured neural and autonomic responses in healthy adult individuals during a semantic conceptual priming task measuring human attachment security "by proxy". Performance during a stress but not a neutral prime condition was associated with response in bilateral amygdalae.

Attachment state of mind and perceptual processing of emotional stimuli.

This study aimed to investigate the relationship between attachment state of mind and perceptual processing of social and non-social, affective, and neutral material. A total of 57 young adults completed the Adult Attachment Interview (AAI) plus an experimental task in which their perceptual thresholds to different types of pictures were assessed. Significant correlations were found between the AAI dimensions and perceptual thresholds for social stimuli such as social interactions or human faces displaying emotional expressions.
