Abstract
A growing body of experimental research now demonstrates that neurologically normal individuals associate different taste qualities with design features such as curvature, symmetry, orientation, texture and movement. The form of everything from the food itself through to the curvature of the plateware on which it happens to be served, and from glassware to typeface, not to mention the shapes of/on food product packaging have all been shown to influence people’s taste expectations, and, on occasion, also their taste/food experiences. Although the origins of shape–taste and other form–taste crossmodal correspondences have yet to be fully worked out, it would appear that shape qualities are occasionally elicited directly. However, more often, there may be a metaphorical attempt to translate the temporal qualities of taste sensations into a spatial analogue. At the same time, emotional mediation may sometimes also play a role in the affinity people experience between shape properties and taste. And finally, it should be acknowledged that associative learning of the relation between packaging shapes, glassware shapes, logos, labels and iconic food forms that commonly co-occur with specific taste properties (i.e., in the case of branded food products) may also play an important role in determining the nature of shape–taste correspondences. Ultimately, however, any attempt to use such shape–taste correspondences to nudge people’s behaviour/perception in the real world is made challenging due to the fact that shape properties are associated with multiple qualities, and not just taste.
Abstract
The integration of vestibular, visual and body cues is a fundamental process in the perception of self-motion and is commonly experienced in an upright posture. However, when the body is tilted in an off-vertical orientation these signals are no longer aligned relative to the influence of gravity. In this study, the perceived timing of visual motion was examined in the presence of sensory conflict introduced by manipulating the orientation of the body, generating a mismatch between body and vestibular cues due to gravity and creating an ambiguous vestibular signal of either head tilt or translation. In a series of temporal-order judgment tasks, participants reported the perceived onset of a visual scene simulating rotation around the yaw axis presented in virtual reality with a paired auditory tone while in an upright, supine and side-recumbent body position. The results revealed that the perceived onset of visual motion was further delayed from zero (i.e., true simultaneity between visual onset and a reference auditory tone) by approximately an additional 30 ms when viewed in a supine or side-recumbent orientation compared to an upright posture. There were also no significant differences in the timing estimates of the visual motion between all the non-upright orientations. This indicates that the perceived timing of visual motion is negatively impacted by the presence of conflict in the vestibular and body signals due to the direction of gravity and body orientation, even when the mismatch is not in the direct plane of the axis of rotation.
Abstract
There are currently five generations: veterans (born 1922–1945), baby boomers (born 1946–1963), generation X (born 1964–1979), generation Y (born 1980–1995) and generation Z (born after 1995). Each person adopts a specific attitude to experiencing the passing of time, i.e., a time perspective. In addition, each person adopts a specific attitude to experiencing the passing time, i.e., a temporal orientation. This study investigates whether members of different generations differ in of terms of their preferred time perspective. The Zimbardo Time Perspective Inventory was used in the study. A total of 435 people were surveyed, out of which 215 (49.4%) were women and 220 (50.6%) men. The subjects were aged 16–81, and the average age for the whole group was M = 45.04, SD = 19.20. The conducted analyses revealed the occurrence of statistically significant differences between generations X, Y, Z and between veterans and baby boomers. In the groups of veterans and baby boomers, the highest intensity was demonstrated for the past positive perspective. Among members of generations X and Y, future perspective was the most preferred one. In generation Z, the hedonistic present and the positive past are the most strongly preferred time perspective. The obtained results can be used in the work with individual generations in order to develop more adaptive profiles of time perspective. This applies in particular to generation Z, which seems to represent the least functional time perspective.
From a Barren Rocky Earth to Artists, Philosophers, Meditators and Psychotherapists
This volume is a newly revised and updated edition of Evolution and Consciousness (Brill, 2019) and provides a comprehensive and accessible introduction to the emerging concept of the evolution of consciousness. The simple, but dynamic, theory of evolving consciousness blends the powerful insights of modern science with the deep wisdom of age-old cultures, synthesising the traditions of East and West, of the head and heart, of male and female and of science and spirituality. To borrow a phrase from American philosopher Ken Wilber, it is a concept that “transcends and includes” all that has gone before. By integrating diverse multi-disciplinary approaches, it provides an overarching and transcending model that moves us to a new level of meaning and understanding of our place in the world, and in so doing deepens our work as psychotherapists.

Abstract
In multisensory environments, our brains perform causal inference to estimate which sources produce specific sensory signals. Decades of research have revealed the dynamics which underlie this process of causal inference for multisensory (audiovisual) signals, including how temporal, spatial, and semantic relationships between stimuli influence the brain’s decision about whether to integrate or segregate. However, presently, very little is known about the relationship between metacognition and multisensory integration, and the characteristics of perceptual confidence for audiovisual signals. In this investigation, we ask two questions about the relationship between metacognition and multisensory causal inference: are observers’ confidence ratings for judgments about Congruent, McGurk, and Rarely Integrated speech similar, or different? And do confidence judgments distinguish between these three scenarios when the perceived syllable is identical? To answer these questions, 92 online participants completed experiments where on each trial, participants reported which syllable they perceived, and rated confidence in their judgment. Results from Experiment 1 showed that confidence ratings were quite similar across Congruent speech, McGurk speech, and Rarely Integrated speech. In Experiment 2, when the perceived syllable for congruent and McGurk videos was matched, confidence scores were higher for congruent stimuli compared to McGurk stimuli. In Experiment 3, when the perceived syllable was matched between McGurk and Rarely Integrated stimuli, confidence judgments were similar between the two conditions. Together, these results provide evidence of the capacities and limitations of metacognition’s ability to distinguish between different sources of multisensory information.

Abstract
A single bout of aerobic exercise is related to positive changes in higher-order cognitive function among older adults; however, the impact of aerobic exercise on multisensory processing remains unclear. Here we assessed the effects of a single bout of aerobic exercise on commonly utilized tasks that measure audiovisual multisensory processing: response time (RT), simultaneity judgements (SJ), and temporal-order judgements (TOJ), in a pilot study. To our knowledge this is the first effort to investigate the effects of three well-controlled intervention conditions on multisensory processing: resting, completing a cognitively demanding task, and performing aerobic exercise for 20 minutes. Our results indicate that the window of time within which stimuli from different modalities are integrated and perceived as simultaneous (temporal binding window; TBW) is malleable and changes after each intervention condition for both the SJ and TOJ tasks. Specifically, the TBW consistently became narrower post exercise while consistently increasing in width post rest, suggesting that aerobic exercise may improve temporal perception precision via broad neural change rather than targeting the specific networks that subserve either the SJ or TOJ tasks individually. The results from the RT task further support our findings of malleability of the multisensory processing system, as changes in performance, as assessed through cumulative probability models, were observed after each intervention condition. An increase in integration (i.e., greater magnitude of multisensory effect) however, was only found after a single bout of aerobic exercise. Overall, our results indicate that exercise uniquely affects the central nervous system and may broadly affect multisensory processing.
