Forward optic flow is prioritised in visual awareness independently of walking direction.

PLoS One 2021 4;16(5):e0250905. Epub 2021 May 4.

Faculty of Psychology, University of Warsaw, Warsaw, Poland.

When two different images are presented separately to each eye, one experiences smooth transitions between them-a phenomenon called binocular rivalry. Previous studies have shown that exposure to signals from other senses can enhance the access of stimulation-congruent images to conscious perception. However, despite our ability to infer perceptual consequences from bodily movements, evidence that action can have an analogous influence on visual awareness is scarce and mainly limited to hand movements.

There is no evidence that meaning maps capture semantic information relevant to gaze guidance: Reply to Henderson, Hayes, Peacock, and Rehrig (2021).

Cognition 2021 Apr 30:104741. Epub 2021 Apr 30.

Cardiff University, Cardiff University Brain Research Imaging Centre (CUBRIC), School of Psychology, Cardiff, United Kingdom.

The concerns raised by Henderson, Hayes, Peacock, and Rehrig (2021) are based on misconceptions of our work. We show that Meaning Maps (MMs) do not predict gaze guidance better than a state-of-the-art saliency model that is based on semantically-neutral, high-level features. We argue that there is therefore no evidence to date that MMs index anything beyond these features. Read More

The role of early and late reflections on perception of source orientation.

J Acoust Soc Am 2021 Apr;149(4):2255

Medizinische Physik and Cluster of Excellence Hearing4all, Universität Oldenburg, Oldenburg 26111, Germany.

Sound radiation of most natural sources, like human speakers or musical instruments, typically exhibits a spatial directivity pattern. This directivity contributes to the perception of sound sources in rooms, affecting the spatial energy distribution of early reflections and late diffuse reverberation. Thus, for convincing sound field reproduction and acoustics simulation, source directivity has to be considered. Read More

Speech intelligibility for various head orientations of a listener in an automobile using the speech transmission index.

J Acoust Soc Am 2021 Apr;149(4):2686

Acoustic Laboratory, School of Physics and Optoelectronics, South China University of Technology, Guangzhou 510641, China.

As well as background noise and the acoustic conditions of the given space, speech intelligibility (SI) is affected by the binaural effect (BE), which is sensitive to the head orientation (HO) of the listener, especially in a small enclosed space such as an automobile. This study uses the speech transmission index (STI) to systematically investigate and predict SI for various HOs of the listener in an automobile. To explore the combined effects of reflections and BE on the auditory perception of speech, several groups of binaural room impulse responses for different speaker locations and HOs are measured in a listening room and an automobile, with the left-side front window (LFW) closed and open, and these are used to calculate the STI.

Feeling younger as a stress buffer: Subjective age moderates the effect of perceived stress on change in functional health.

Psychol Aging 2021 May;36(3):322-337

German Centre of Gerontology.

Feeling younger than one's chronological age is associated with various beneficial health outcomes. However, apart from these direct health effects, little is known about the role of subjective age as a potential "buffer" and compensatory resource that might counteract the detrimental effect of health risk factors. We investigated whether the effect of perceived stress as a major health risk factor on change in functional health is smaller among individuals who feel younger. Read More
