Evaluation of colour vision impairment during acute hypobaric hypoxia in aviation medicine: a randomized controlled trial.

The digitization of aircraft cockpits places high demands on the colour vision of pilots. The present study investigates colour vision changes upon acute exposure to hypobaric hypoxia. The digital Waggoner Computerized Color Vision Test and the Waggoner D-15 were performed by 54 healthy volunteers in a decompression chamber.

Pancultural nostalgia in action: Prevalence, triggers, and psychological functions of nostalgia across cultures.

Nostalgia is a social, self-relevant, and bittersweet (although mostly positive) emotion that arises when reflecting on fond past memories and serves key psychological functions. The majority of evidence concerning the prevalence, triggers, and functions of nostalgia has been amassed in samples from a handful of largely Western cultures. If nostalgia is a fundamental psychological resource, it should perform similar functions across cultures, although its operational dynamics may be shaped by culture.

Crying does not alleviate acute pain perception: Evidence from an experimental study.

Background: Whereas previous studies revealed positive effects of emotional expressions such as swearing and laughing on acute pain, systematic research on the effects of crying on pain is missing. The rationale for the current study is that either a mere emotional distraction or changes in oxytocin and opioid levels represent a mechanism through which crying modulates pain, with the timing of mood changes as crucial information for distinguishing between potential mechanisms.

Methods: In two studies, we exposed participants (Study 1: n = 57; Study 2: n = 70) to a sad movie and measured their mood, and exposed them to pain induction procedures (electric shock and cold-pressor test, respectively) before and after the film.

Music and Lyric Characteristics of Popular Dutch Funeral Songs.

This study compared the characteristics of 150 songs (Dutch lyrics, = 47, English lyrics, = 103), popular at Dutch funerals, to an equal number of non-funeral songs. The variables explored included those linked with the music (valence, energy, danceability, acousticness, key, and tempo); and lyrics, namely: linguistics-related (first-person singular/plural, second-person pronouns; past, present, future tense; expressed emotion (positive, negative words, and the discrete emotional categories anger, anxiety, sadness); and category words (those relating to family, friends, death, religion). Funeral music was lower in valence, energy, and danceability and higher in acousticness than non-funeral music.

A clinical practice review of crying research.

The goal of this clinical practice review is to assess the current state of the theoretical and empirical literature on emotional crying (i.e., crying in response to an emotional stimulus), a topic that has received surprisingly limited attention of behavioral scientists and clinicians.
