“…Classification times were also significantly faster when the words were presented to the right than to the left auditory channel, t(41) = 2.19, p = .034. The overall pattern was therefore skewed to the right reflecting a general bias due to hemispheric asymmetry with verbal information presented to the right ear being processed more efficiently (e.g., Belin et al, 1998;Kimura, 1961).…”

Embodiment of abstract categories in space… grounding or mere compatibility effects? The case of politics

In two experiments, the role played by stimulus response compatibility in driving the spatial grounding of abstract concepts is examined. In experiment 1, participants were asked to classify politics-related words appearing to the left or the right side of a computer monitor as socialist or conservative. Responses were given by pressing vertically aligned keys and thus orthogonal to the spatial information that may have been implied by the words. Responses given by left or right index finger were counterbalanced. In experiment 2, a lexical decision task, participants categorized political words or non-words presented to the left or the right auditory channels, by pressing the top/bottom button of a response box. The response category labels (word or non-word) were also orthogonal to the spatial information that may have been implied by the stimulus words. In both experiments, responses were faster when socialism-related words were presented on the left and conservatism-related words were presented on the right, irrespective of the reference of the response keys or labels. Overall, our findings suggest that the spatial grounding of abstract concepts (or at least politics-related ones) is independent of experimentally driven stimulusresponse compatibility effects.Keywords: spatial grounding, abstract concepts, compatibility effects, politics 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 Embodiment of abstract categories in space… grounding or mere compatibility effects?

“…One such study was carried out by Belin et al (1998) who used positron emission tomography (PET) to examine processing of formant transitions of different durations in pseudospeech syllables. The principal finding was that whereas left auditory cortical response was similar to both slower and faster transitions, the right auditory cortex responded best to the slower transitions, indicating a differential sensitivity to speed of spectral change.…”

The idea that speech processing relies on unique, encapsulated, domain-specific mechanisms has been around for some time. Another well-known idea, often espoused as being in opposition to the first proposal, is that processing of speech sounds entails general-purpose neural mechanisms sensitive to the acoustic features that are present in speech. Here, we suggest that these dichotomous views need not be mutually exclusive. Specifically, there is now extensive evidence that spectral and temporal acoustical properties predict the relative specialization of right and left auditory cortices, and that this is a parsimonious way to account not only for the processing of speech sounds, but also for non-speech sounds such as musical tones. We also point out that there is equally compelling evidence that neural responses elicited by speech sounds can differ depending on more abstract, linguistically relevant properties of a stimulus (such as whether it forms part of one's language or not). Tonal languages provide a particularly valuable window to understand the interplay between these processes. The key to reconciling these phenomena probably lies in understanding the interactions between afferent pathways that carry stimulus information, with top-down processing mechanisms that modulate these processes. Although we are still far from the point of having a complete picture, we argue that moving forward will require us to abandon the dichotomy argument in favour of a more integrated approach.

“…Functional imaging studies using PET or fMRI in healthy adults have demonstrated that the response to rapid auditory stimuli, in the form of rapid frequency transitions, is greater over the left hemisphere than the right, highlighting the importance of the left hemisphere for the processing of auditory information containing rapid transitions (Belin et al, 1998;Zaehle et al, 2004). Zaehle and colleagues reported exclusively left-sided activations in Heschl's gyrus and the planum temporale associated with the perception of both short gaps and stop consonant-vowel syllables.…”

Development of structure and function in the infant brain: Implications for cognition, language and social behaviour

Recent advances in cognitive neuroscience have allowed us to begin investigating the development of both structure and function in the infant brain. However, despite the rapid evolution of technology, surprisingly few studies have examined the intersection between brain and behaviour over the first years of life. Even fewer have done so in the context of a particular research question. This paper aims to provide an overview of four domains that have been studied using techniques amenable to elucidating the brain/behaviour interface: language, face processing, object permanence, and joint attention, with particular emphasis on studies focusing on early development. The importance of the unique role of development and the interplay between structure and function is stressed throughout. It is hoped that this review will serve as a catalyst for further thinking about the substantial gaps in our understanding of the relationship between brain and behaviour across development. Further, our aim is to provide ideas about candidate brain areas that are likely to be implicated in particular behaviours or cognitive domains.
