Perceiving college peers’ alcohol consumption: temporal patterns and individual differences in overestimation

Objective: This study examines temporal patterns and individual differences of overestimation in alcohol norm perception within a social network.

Design: Hundred psychology freshmen indicated biweekly during their first semester the drinks they consumed, the perceived average of their peers’ consumption, and with whom they were acquainted. At baseline, trait self-control was assessed.

Main outcome: The moderation of alcohol consumption overestimation by time and individual characteristics was explored.

Results: Results show that students overestimated alcohol consumption of their acquainted peers by 1.22 drinks (p?<?.001). For time periods at which peers reported high consumption, overestimation decreased. Additionally, individuals reporting high alcohol consumption (b?=??0.25, p?<?.001) and low self-control (b?=?0.27, p?=?.010) showed higher overestimation.

Conclusions: Students overestimate the alcohol consumption of peers not fully accounting for changes in peer-reports. Furthermore, individual differences suggest informational and motivational processes underlying overestimation.     

Combining Action Observation and Motor Imagery Improves Eye–Hand Coordination during Novel Visuomotor Task Performance

Abstract

In this study, we compared the effectiveness of concurrent action observation and motor imagery (AO?+?MI), observing with the intent to imitate (active observation; AO), and passive observation (PO) training interventions for improving eye–hand coordination. Fifty participants were assigned to five groups [AO?+?MI, AO, PO, physical practice (PP); control] and performed a visuomotor rotation task, whilst eye movements were recorded. Each participant then performed 20 task trials in a training intervention before repeating the visuomotor rotation task in a post-test. As expected, PP produced the greatest improvement in task performance and eye–hand coordination. However, in comparison to the control group, AO?+?MI training produced a statistically significant increase in both task performance and eye–hand coordination, but no such improvements were found following AO or PO.     

Nursing Home Adaptation in Visually Impaired Older Adults Using a Narrative Approach1,2

This study used a narrative approach to examine the difficulties that older visually impaired people experience when adapting to life in a nursing home. The interview data were collected from one blind aged person (n = 1), focusing on the adaptation process from moving into the nursing home to the present and maintaining context of narrative that included the life history. Subcategories were extracted based on a framework of temporal coherence, causal coherence, thematic coherence, and situational coherence. This study revealed three factors related to adaptation to life in a nursing home for a visually impaired person, including psychological adaptation: becoming accustomed to life in the facility after changes in the living environment, having gratitude and maintaining “moderating human relationships,” and participating in activities connected to one's purpose in life. He was able to psychologically adapt and came to accept his death through an awareness of aging.     

Behavioural interventions for micro-mobility adoption: Low-hanging fruits or hard nuts to crack?

This study explores the potential and challenges of applying behavioural interventions to promote micro-mobility adoption. Our online experiments with New York City residents showed that nudges and faming improved respondents’ willingness to adopt e-scooters significantly. Moreover, our experiments spanned over the pre-, during- and post- COVID-19 lockdown period in New York City. Findings from this natural experiment revealed that the effect of these behavioural interventions varied significantly during the pandemic, likely due to a heightened level of health consciousness and a new perspective regarding social interactions. Behavioural tools cannot be taken off-the-shelf and applied as a blanket policy. Individual and group characteristics have to be assessed to devise the pre-eminent behavioural interventions for a particular target audience. More experiments across a wide range of economic, social, cultural, and political settings are needed to guide the application of behavioural interventions in transportation studies.
