Mental rotation of cubes with a snake face: The role of the human-body analogy revisited

ABSTRACT

Previous research has demonstrated repeatedly that the mental rotation of human-like objects can be performed more quickly than the mental rotation of abstract objects (a body analogy effect). According to existing accounts, the body analogy effect is mediated by projections of one’s own body axes onto objects (spatial embodiment), and the mental emulation of the observed body posture (motoric embodiment). To test whether motoric embodiment facilitates the mental rotation of human-like objects, we conducted an experiment using a snake-like object that had its own body axes but would be difficult to emulate. Twenty-four participants performed the mental rotation of snake-shaped cubes with or without a snake face as well as human-shaped cubes with or without a human face. Results showed that the presence of a face increased mental rotation speeds for both human-shaped and snake-shaped cubes, confirming both the human-body and snake analogy effects. More importantly, the snake analogy effect was equal to the human-body analogy effect. These findings contradict the motoric embodiment account and suggest that any object that can be regarded as a unit facilitates holistic mental rotation, which in turn leads to improved performance.     

Taking a Step Back,Moving Forward: Place and Space without Mental Representations

ABSTRACT

The publication of the revised edition of Place and Experience provides the occasion to discuss Malpas’ original account of place, and its role in a proper account of the central features of human minds. The first edition is a groundbreaking work on the embodiment and embeddedness of human minds, that prefigures more recent developments of a now established field of research on embodied minds: so-called E accounts. In this paper, I address three issues in Malpas’ book that I found problematic at times and unclear at others, and argue that E- accounts, or better, a particular rendering of them, can better dissolve. These interrelated issues are: 1. the use of the idea of mental representations to understand location and orientation; 2. the claim that non-human animals have ‘environments’ but lack ‘worlds’, 3. the use of two exclusive vocabularies, the physical and the mental, for describing cognition. I thus question such ideas, associated with traditional accounts of cognition, which not only are responsible for some of the gravest criticisms such accounts have received, but seem inadequate to Malpas’ characterization of minds as placed. My recommendation is to take a step back from the traditional framework, and allow ourselves to simply move forward.     

Revisiting the past and back to the future: Horizons of cognition and emotion research

ABSTRACT

To commemorate that Cognition & Emotion was established three decades ago, we asked some distinguished scholars to reflect on past research on the interface of cognition and emotion and prospects for the future. The resulting papers form the Special Issue on Horizons in Cognition and Emotion Research. The contributions to Horizons cover both the field in general and a diversity of specific topics, including affective neuroscience, appraisal theory, automatic evaluation, embodied emotion, emotional disorders, emotion-linked attentional bias, emotion recognition, emotion regulation, lifespan development, motivation, and social emotions. We hope that Horizons will spark constructive debates, while offering guidance for the future growth and development of research on the interface between cognition and emotion. Finally, we provide an update on how Cognition & Emotion has fared over the past year, and announce some changes in editorial policies and the editorial board.     

Using neural response properties to draw the distinction between modal and amodal representations

ABSTRACT

Barsalou has recently argued against the strategy of identifying amodal neural representations by using their cross-modal responses (i.e., their responses to stimuli from different modalities). I agree that there are indeed modal structures that satisfy this “cross-modal response” criterion (CM), such as distributed and conjunctive modal representations. However, I argue that we can distinguish between modal and amodal structures by looking into differences in their cross-modal responses. A component of a distributed cell assembly can be considered unimodal because its responses to stimuli from a given modality are stable, whereas its responses to stimuli from any other modality are not (i.e., these are lost within a short time, plausibly as a result of cell assembly dynamics). In turn, conjunctive modal representations, such as superior colliculus cells in charge of sensory integration, are multimodal because they have a stable response to stimuli from different modalities. Finally, some prefrontal cells constitute amodal representations because they exhibit what has been called ‘adaptive coding’. This implies that their responses to stimuli from any given modality can be lost when the context and task conditions are modified. We cannot assign them a modality because they have no stable relation with any input type.

Dancing faith: contemporary Christian dance in Norway

ABSTRACT

Although dance is a common religious expression, its place in the Christian tradition has been contested. In modern Protestant Norway, dance has mostly been considered irrelevant to church life or even sinful. In recent decades, however, dance has become increasingly common in Norwegian churches. The present analysis of empirical data on dance in Christian settings in contemporary Norway is based on participant observation and interviews. While younger dancers (born after 1990) consider it natural to dance in church, and are usually welcome to do so, older participants have met significant resistance. When dancing, dancers find personal meaning (wellbeing, processing emotions and life events), social meaning (communication, belonging), and religious meaning (contact with God, prayer, growth). Dance emerges as a part of lived religion that clearly highlights how bodies matter, and how spiritualities are gendered, in this contribution to understanding the embodied dimensions of religion.     

Analysis of the Movement-Inducing Effects of Music through the Fractality of Head Sway during Standstill

Abstract

The links between music and human movement have been shown to provide insight into crucial aspects of human’s perception, cognition, and sensorimotor systems. In this study, we examined the influence of music on movement during standstill, aiming at further characterizing the correspondences between movement, music, and perception, by analyzing head sway fractality. Eighty seven participants were asked to stand as still as possible for 500?seconds while being presented with alternating silence and audio stimuli. The audio stimuli were all rhythmic in nature, ranging from a metronome track to complex electronic dance music. The head position of each participant was captured with an optical motion capture system. Long-range correlations of head movement were estimated by detrended fluctuation analysis (DFA). Results agree with previous work on the movement-inducing effect of music, showing significantly greater head sway and lower head sway fractality during the music stimuli. In addition, patterns across stimuli suggest a two-way adaptation process to the effects of music, with musical stimuli influencing head sway while at the same time fractality modulated movement responses. Results indicate that fluctuations in head movement in both conditions exhibit long-range correlations, suggesting that the effects of music on head movement depended not only on the value of the most recent measured intervals, but also on the values of those intervals at distant times.
