Reproducibility is a defining feature of science, but the extent to which it characterizes current research unknown. We conducted replications 100 experimental and correlational studies published in three psychology journals using high-powered designs original materials when available. Replication effects were half magnitude effects, representing substantial decline. Ninety-seven percent had statistically significant results. Thirty-six results; 47% effect sizes 95% confidence interval...
ABSTRACT Aims Attentional bias for drug‐related cues has been associated with drug maintenance and relapse. We investigated whether attentional smoking‐related stimuli could be altered using a modified visual probe task in cigarette smokers. also sought to determine changes were subsequent craving cue reactivity. Participants Male female ( n = 54) current smokers (≥5 cigarettes per day), aged between 18 40 years, recruited from staff students of the University Bristol, general population....
Previous research with adults and adolescents indicates that plain cigarette packs increase visual attention to health warnings among non-smokers non-regular smokers, but not regular smokers. This may be because smokers: (1) are familiar the warnings, (2) preferentially attend branding, or (3) actively avoid warnings. We sought distinguish between these explanations using eye-tracking technology.A convenience sample of 30 adult dependent smokers participated in an study. Participants viewed...
Judgements of volume may influence the rate consumption alcohol and, in turn, amount consumed. The aim current study was to examine impact size and shape wine glasses on perceptions volume.Online experiment: Participants (n = 360; recruited via Mechanical Turk) were asked match two glasses, specifically: 1. Reference glass holding a fixed reference volume, 2. Comparison glass, for which could be altered until participants perceived it matched volume. One three comparison shown each trial:...
Background High levels of alcohol consumption and increases in heavy episodic drinking (binge drinking) are a growing public concern, due to their association with increased risk personal societal harm. Alcohol has been shown be sensitive factors such as price availability. The aim this study was explore the influence glass shape on rate alcoholic non-alcoholic beverages. Methods This an experimental design beverage (lager, soft drink), (straight, curved) quantity (6 fl oz, 12 oz)...
Alcohol labeling provides a relatively low-cost, population-level approach to providing information about alcohol's content and harms.We conducted an online between-subjects experiment with two tasks examine the impact of alcohol labels (n = 1884). In one task, participants were randomized view four different unit (including currently used by industry novel which provide more how number units relates recommended drinking guidelines). We assessed participants' accuracy estimating weekly...
High trait anxiety has been associated with detriments in emotional face processing. By contrast, relatively little is known about the effects of state on We investigated recognition expressions (anger, sadness, surprise, disgust, fear and happiness) experimentally, using 7.5% carbon dioxide (CO 2 ) model to induce anxiety, a large observational study. The experimental studies indicated reduced global (rather than emotion-specific) emotion accuracy increased interpretation bias (a tendency...
Static high contrast ('dazzle') patterns, such as zigzags, have been shown to reduce the perceived speed of an object. It has not escaped our notice that this effect possible military applications and here we report a series experiments on humans, designed establish whether dynamic dazzle patterns can cause distortions sufficient provide effective defence in field, extent which these effects are robust battery manipulations. Dynamic stripe moving same direction target found increase target,...
State anxiety appears to influence facial emotion processing (Attwood et al. 2017 R. Soc. Open Sci.4, 160855). We aimed (i) replicate these findings and (ii) investigate the role of trait anxiety, in an experiment with healthy UK participants (N = 48, 50% male, high anxiety). High low state were induced via inhalations 7.5% carbon dioxide enriched air medical air, respectively. reduced global recognition accuracy (p 0.01, ηp2=0.14 ), but it did not affect interpretation bias towards...
Many women consume alcohol while pregnant before they are aware of the pregnancy, raising concerns about potential harms to developing fetus. Official guidelines in United Kingdom recommend abstinence throughout and many turn online forums for reassurance information. However, can also become a source misinformation, potentially increasing confusion anxiety among who have consumed pregnancy awareness. This study explored discussions consumption awareness on Mumsnet understand nature peer...
Previous studies suggest that smoking and higher alcohol consumption are associated with greater type 2 diabetes (T2D) risk. However, examining whether this reflects causal relationships limited often do not consider continuous glycaemic traits. We conducted both two-sample one-sample Mendelian randomisation (MR), using publicly available GWAS data UK Biobank data, respectively, to examine the potential effects of lifetime index (LSI) alcoholic drinks per week (DPW) on T2D traits (fasting...
To investigate the impact of unit and calorie information on drinking behaviour in an ad libitum taste test paradigm. In this experimental human laboratory study, participants were randomized to one four conditions, balanced by gender, using a 2 (unit information: present vs. absent) × (calorie between-subjects design. The percentage beer consumed during was primary outcome measure. Among largely undergraduate student population, we found no evidence that either or impacted alcohol...
We examined whether enhancing self-affirmation among a population of drinkers, prior to viewing threatening alcohol pictorial health warning labels, would reduce defensive reactions and promote related behaviour change. also how severity influences these there is an interaction between severity. In this experimental human laboratory study, participants (n = 128) were randomised or control group. After the manipulation was administered, we tracked participants' eye movements while they viewed...
The study aimed to estimate the impact of introducing a draught alcohol-free beer, thereby increasing relative availability these products, on alcohol sales and monetary takings in bars pubs England.
