When the smile is a cue to familiarity

2000

International audience; The question discussed in the two following experiments concerns the effect of facial expressions on face recognition. Famous and unknown faces with neutral or smiling expression were presented for different inspection durations (15 ms vs 1000 ms). Subjects had to categorize these faces as famous or unknown (Experiment 1), or estimate their degree of familiarity on a rating scale (Experiment 2). Results showed that the smile increased ratings of familiarity for unfamiliar faces (Experiments 1 and 2) and for famous faces (Experiment 2). These data are discussed in the framework of current face-recognition models and are interpreted in terms of social value of the smil…

Global flow impacts time-to-passage judgments based on local motion cues

2011

AbstractWe assessed the effect of the coherence of optic flow on time-to-passage judgments in order to investigate the strategies that observers use when local expansion information is reduced or lacking. In the standard display, we presented a cloud of dots whose image expanded consistent with constant observer motion. The dots themselves, however, did not expand and were thus devoid of object expansion cues. Only the separations between the dots expanded. Subjects had to judge which of two colored target dots, presented at different simulated depths and lateral displacements would pass them first. Image velocities of the target dots were chosen so as to correlate with time-to-passage only…

Wearing glasses to hear differently? Aftereffects of visuomanual prismatic adaptation on auditory perception

2022

Sensorimotor plasticity is defined as the ability to produce an appropriate motor response face to environmental or bodily changes. The classical experimental paradigm to study sensorimotor plasticity is prism adaptation, which consists of pointing to visual targets while wearing prisms that shift the visual field laterally or vertically. Its aftereffects are not restricted to sensorimotor behavior but extend to sensorial modalities not directly involved during prism exposition, such as audition. There exists a mental representation of auditory frequencies in which low auditory frequencies are associated with the left part of space and high auditory frequencies with the right part of space.…

Tobacco Use Documenting Policy and Its Association With Pupils’ Smoking and Their Perception of the Enforcement of School Smoking Bans in Finland

2014

Finnish national data sets on schools (N = 496) and pupils (N = 74,143; 14–16 years) were used to study whether a systematic documenting policy for the violations of school smoking bans was associated with pupils’ smoking and their perceptions on the enforcement of smoking bans. Attending a school with a systematic documenting policy was associated with perceptions that smoking is prohibited and restrictions monitored, with lower levels of smoking in the vicinity of the school during the school day, but not with smoking prevalence. Findings suggest that a consistent documenting policy could be an effective tool for reducing pupils’ smoking in schools.

Challenges of tourism development in winter sports destinations and for post-event tourism marketing: the cases of the Ramsau Nordic Ski World Champi…

2013

Previous research on winter sport destinations which have hosted big sport events suggested that there is a gap between the relevance of the systematic considerations of the specific challenges of tourism destination marketing and common practice. The study therefore investigates through individual interviews with key stakeholders (1) the level of agreement with central theoretical statements among stakeholders and key decision-makers at the Austrian destinations Ramsau (a traditional Nordic destination) and St Anton (a traditional Alpine destination) and (2) the relevance of this knowledge to the practical work of the key decision-makers at the destinations. The results show that there is …

ODOUR STUDY WITH QUALITATIVE AND QUANTITATIVE RESEARCH METHODS IN VARIOUS DISTRICTS OF RIGA

2017

Different emission sources of odours become increasingly important environmental problem which may have a negative impact on human health and quality of life. Human odour perception may be subjective, however on odour perception threshold is considered to be the odorant concentration where at least half of odour assessor’s group members confirm the existence of odour, and then it is 1 OUE /m3. Nowadays more and more advanced technologies are used to measure odour concentration. Olfactometer Scentroid SM100 allows users to accurately quantify ambient odour concentration in field. Also this equipment allows to collect source samples and analyze odour in a laboratory. Odour study in 2016 and 2…

Distraction of cyclists: how does it influence their risky behaviors and traffic crashes?

2018

BackgroundUndisputedly, traffic crashes constitute a public health concern whose impact and importance have been increasing during the past few decades. Specifically, road safety data have systematically shown how cyclists are highly vulnerable to suffering traffic crashes and severe injuries derived from them. Furthermore, although the empirical evidence is still very limited in this regard, in addition to other human factors involved in cycling crashes, distractions while cycling appear to be a major contributor to the road risk of cyclists.ObjectivesThe main objectives of this study were, first, to explore the prevalence and trends of cycling distractions within an international sample o…

Action Observation Network Activity Related to Object-Directed and Socially-Directed Actions in Adolescents

2020

The human action observation network (AON) encompasses brain areas consistently engaged when we observe other's actions. Although the core nodes of the AON are present from childhood, it is not known to what extent they are sensitive to different action features during development. Because social cognitive abilities continue to mature during adolescence, the AON response to socially-oriented actions, but not to object-related actions, may differ in adolescents and adults. To test this hypothesis, we scanned with functional magnetic resonance imaging (fMRI) male and female typically-developing teenagers (n= 28; 13 females) and adults (n= 25; 14 females) while they passively watched videos of…

Practitioner views of goodwill accounting under US GAAP

2020

PurposeAccounting standards for goodwill may intensify the agency conflict. Since auditors evaluate intangible asset valuations, this study examines to what extent being an auditor (including Big 4 auditors) and being female as indicators of professional skepticism and conservatism predict accounting professionals' critical views of goodwill accounting under US GAAP.Design/methodology/approachStatistical analyses of a survey of accounting professionals in the Pacific Northwest region of the United States.FindingsThe respondents' views are dispersed from trust in GAAP to views reflecting management opportunism in goodwill accounting. While being an auditor (including Big 4 auditors) does not…
