Ambivalence over emotional expression in major depression

High ambivalence over the expression of emotions (AEE) has consistently been associated with high levels of depression in previous research. However, there is a lack of studies examining this construct and its associations in a clinical sample of patients with major depressive disorder (MDD). Therefore, the present study compared 76 MDD with 77 non-depressed controls (NC) regarding AEE. As expected, MDD reported greater AEE as compared to ND. Furthermore, levels of AEE and levels of depression were positively correlated in the MDD group. These findings extend previous work and underline the importance of AEE as a central construct in depression. Targeting AEE in treatments of depression may help to modify maladaptive interpersonal patterns of emotional expression.     

Having Responsive Facebook Friends Affects the Satisfaction of Psychological Needs More Than Having Many Facebook Friends

The use of social networking sites, such as Facebook, provides ample opportunities for the pursuit of interpersonal connection but may also bring to mind one's social isolation. The present research examined the effects of interpersonal neglect (i.e., low number of responding Facebook friends) on the satisfaction of fundamental human needs. Two studies revealed that receiving few responses from one's Facebook friends threatens the needs for belonging, self-esteem, control, and meaningful existence. These effects were observable over and above the impact of general social connection to others (i.e., total number of Facebook friends) and tone of responses.     

The discrimination of angry and fearful facial expressions in 7-month-old infants: An event-related potential study

The important ability to discriminate facial expressions of emotion develops early in human ontogeny. In the present study, 7-month-old infants’ event-related potentials (ERPs) in response to angry and fearful emotional expressions were measured. The angry face evoked a larger negative component (Nc) at fronto-central leads between 300 and 600 ms after stimulus onset when compared to the amplitude of the Nc to the fearful face. Furthermore, over posterior channels, the angry expression elicited a N290 that was larger in amplitude and a P400 that was smaller in amplitude than for the fearful expression. This is the first study that shows that the ability of infants to discriminate angry and fearful facial expressions can be measured at the electrophysiological level. These data suggest that 7-month-olds allocated more attentional resources to the angry face as indexed by the Nc. Implications of this result may be that the social signal values were perceived differentially, not merely as “negative”. Furthermore, it is possible that the angry expression might have been more arousing and discomforting for the infant compared with the fearful expression.     

There's no “I” in team: Effects of cooperative video games on cooperative behavior

The present research tests the idea that playing a team‐player video game in which players work together as teammates and assist each other in achieving a common goal increases cooperative behavior toward a new partner. In fact, relative to a single‐player mode, cooperatively playing a video game increased cooperation in a mixed‐motive decision dilemma task. Because the players were exposed to the same video game content in both experimental conditions, the effect on cooperative behavior can only be accounted for by the different way the game was played. Mediation analyses revealed that cooperative team play promoted feelings of cohesion, which activated trust (i.e., the expectation of reciprocal cooperation), which in turn increased cooperative behavior.

Home Sweet Home! Does Moving Have (Lasting) Effects on Housing Satisfaction?

Previous research has found that moving has lasting effects on housing satisfaction while adaptation to changing living environments is surprisingly absent from this research. This paper challenges and extends this current state of research. Using data from a large-scale German household panel we find that housing satisfaction (a) sharply declines before the move (self-selection into relocation), (b) substantially increases after moving (relocation effect), (c) declines in the following years (adaptation), (d) after about 2 years reaches satisfaction levels similar to the levels several years before the move (full adaptation), (e) but due to selection into moving stays above satisfaction levels in the years directly before the move (lasting gains due to self-selection). Further analyses indicate that moving due to house-related reasons leads to partly lasting gains, while moving due to significant life events only has temporary effects. Finally, we show that permanent changes in housing satisfaction due to house-related relocations can be fully explained using self-assessed comparisons between old and new living environment.     

Detecting distortions of peripherally presented letter stimuli under crowded conditions

When visual features in the periphery are close together they become difficult to recognize: something is present but it is unclear what. This is called “crowding”. Here we investigated sensitivity to features in highly familiar shapes (letters) by applying spatial distortions. In Experiment 1, observers detected which of four peripherally presented (8 deg of retinal eccentricity) target letters was distorted (spatial 4AFC). The letters were presented either isolated or surrounded by four undistorted flanking letters, and distorted with one of two types of distortion at a range of distortion frequencies and amplitudes. The bandpass noise distortion (“BPN”) technique causes spatial distortions in Cartesian space, whereas radial frequency distortion (“RF”) causes shifts in polar coordinates. Detecting distortions in target letters was more difficult in the presence of flanking letters, consistent with the effect of crowding. The BPN distortion type showed evidence of tuning, with sensitivity to distortions peaking at approximately 6.5 c/deg for unflanked letters. The presence of flanking letters causes this peak to rise to approximately 8.5 c/deg. In contrast to the tuning observed for BPN distortions, RF distortion sensitivity increased as the radial frequency of distortion increased. In a series of follow-up experiments, we found that sensitivity to distortions is reduced when flanking letters were also distorted, that this held when observers were required to report which target letter was undistorted, and that this held when flanker distortions were always detectable. The perception of geometric distortions in letter stimuli is impaired by visual crowding.     

In the Face of Terrorism: Evidence that Belief in Literal Immortality Reduces Prejudice Under Terrorism Threat

Based on terror management theory, previous research has shown that terrorism threat increases prejudice against Muslims and is mediated by death‐related thoughts. Because this effect was found on a correlational level, it remains unclear whether terrorism threat increases prejudice against Muslims because of enhanced death‐related thoughts or the opposite: terrorism threat increases death‐related thoughts because of stronger prejudice against Muslims. To disentangle this shortcoming, we varied death‐related thoughts by systematically manipulating the belief in literal immortality. Using two studies, we found that participants exposed to terrorism pictures (vs. controls) had increased prejudice against both Muslims (Study 1) and immigrants (Study 2) when they were led to believe that literal immortality does not exist but not when they were led to believe that it does exist. Mediation analysis indicated that this effect was mediated by death‐related thoughts. This provides further evidence that terrorism threat increases prejudice because of death‐related thoughts.     

Hail the impossible: p-values, evidence, and likelihood

Significance testing based on p-values is standard in psychological research and teaching. Typically, research articles and textbooks present and use p as a measure of statistical evidence against the null hypothesis (the Fisherian interpretation), although using concepts and tools based on a completely different usage of p as a tool for controlling long-term decision errors (the Neyman-Pearson interpretation). There are four major problems with using p as a measure of evidence and these problems are often overlooked in the domain of psychology. First, p is uniformly distributed under the null hypothesis and can therefore never indicate evidence for the null. Second, p is conditioned solely on the null hypothesis and is therefore unsuited to quantify evidence, because evidence is always relative in the sense of being evidence for or against a hypothesis relative to another hypothesis. Third, p designates probability of obtaining evidence (given the null), rather than strength of evidence. Fourth, p depends on unobserved data and subjective intentions and therefore implies, given the evidential interpretation, that the evidential strength of observed data depends on things that did not happen and subjective intentions. In sum, using p in the Fisherian sense as a measure of statistical evidence is deeply problematic, both statistically and conceptually, while the Neyman-Pearson interpretation is not about evidence at all. In contrast, the likelihood ratio escapes the above problems and is recommended as a tool for psychologists to represent the statistical evidence conveyed by obtained data relative to two hypotheses.     

What exactly are victim-sensitive persons sensitive to?

Research has repeatedly shown that people who are habitually sensitive towards unjust victimizations tend to behave uncooperatively and hostile under certain circumstances. But what exactly is the underlying motivation for such uncooperativeness? One explanation is that victim-sensitive individuals behave uncooperatively in order to retribute fateful disadvantages in the past; an alternative explanation is that victim-sensitive individuals behave uncooperatively in order to avoid being exploited in the future. Two experimental studies are presented in which participants were confronted with an unfavorable outcome that was either due to bad luck or to another person’s mean intentions. Findings from both studies suggest that victim-sensitive individuals are specifically sensitive towards mean intentions, but not to fateful disadvantages in general.     

Drugs as instruments from a developmental child and adolescent psychiatric perspective

Developmental, epidemiological, and neurobiological studies indicate that the adaptive and maladaptive functions, as well as immediate and long-term consequences of drug use, may vary by age. Early initiation seems to be associated with a reduced ability to use drugs purposely in a temporally stable, non-addictive manner. Prevention strategies should consider social environmental factors and aim to delay age at initiation.
