Conditional reasoning,frequency of counterexamples,and the effect of response modality

Geiger and Oberauer (2007) found that when asked to reason with conditionals, people are very sensitive to information about the relative frequency of exceptions to conditional rules and quite insensitive to the relative number of disabling conditions. They asked participants to rate their degree of certainty in a conclusion. In the following studies, we investigated the possibility that this kind of response encourages a more probabilistic mode of processing compared with the usual dichotomous response. In Study 1, participants were given a variant of the problems used by Geiger and Oberauer with either the samescaled response format or a dichotomouscategorical response. The results with the scaled response were identical to those of Geiger and Oberauer. However, the results with the categorical response presented a very different profile. In Study 2, we presented similar problems using only frequency information, followed by a set of abstract conditional reasoning problems. The participants who performed better on the abstract problems showed a significantly different response profile than those who did worse on the abstract problems in the categorical response condition. No such difference was observed in the scaled response condition. These results show that response modality strongly affects the way in which information is processed in otherwise identical inferential problems and they are consistent with the idea that scaled responses promote a probabilistic mode of processing.     

Perceptual and motor attribute ratings for 559 object concepts

To understand how and when object knowledge influences the neural underpinnings of language comprehension and linguistic behavior, it is critical to determine the specific kinds of knowledge that people have. To extend the normative data currently available, we report a relatively more comprehensive set of object attribute rating norms for 559 concrete object nouns, each rated on seven attributes corresponding to sensory and motor modalities??color, motion, sound, smell, taste, graspability, and pain??in addition to familiarity (376 raters, M = 23 raters per item). The mean ratings were subjected to principal-components analysis, revealing two primary dimensions plausibly interpreted as relating to survival. We demonstrate the utility of these ratings in accounting for lexical and semantic decision latencies. These ratings should prove useful for the design and interpretation of experimental tests of conceptual and perceptual object processing.     

The Sound of Smell: Associating Odor Valence With Disgust Sounds

Olfaction has recently been highlighted as a sense poorly connected with language. Odor is difficult to verbalize, and it has few qualities that afford mimicry by vision or sound. At the same time, emotion is thought to be the most salient dimension of an odor, and it could therefore be an olfactory dimension more easily communicated. We investigated whether sounds imitative of an innate disgust response can be associated with unpleasant odors. In two experiments, participants were asked to make a forced choice between a pseudoword including a disgust sound and a neutral pseudoword, for pleasant and unpleasant odors. Overall, participants chose more disgust pseudowords than neutral pseudowords for unpleasant odors, but this was not the case for pleasant odors. This effect was not driven by a general association between unpleasant sounds and unpleasant odors, but specifically the sounds [x/χ] and [f], thought to reflect physical responses to disgusting odors, as seen in the Polish fu! or the English ugh!. In line with growing evidence that language can encode odor, we provide the first experimental evidence for an association between the sound of a word and odor valence.     

Phenomenal characteristics of guided imagery,natural imagery,and autobiographical memories

Research indicates that guided imagery experiences can be mistaken for actual experiences under some circumstances. One explanation for such effects is that memory representations of guided imagery and actual events contain similar phenomenal characteristics such as sensory and contextual details, making the source of the events less distinguishable. This study examined this prediction, comparing memory characteristic ratings for guided imagery experiences with those for memories of perceived and natural imagery events (e.g., fantasies). Results replicated previous findings for the difference between perceived and natural imagery memories. Guided imagery ratings were also lower than those for perceived memories for most sensory details (sound, smell, and taste) and temporal details. However, guided imagery ratings for reflective details were lower than both perceived and natural imagery memory ratings. Thus, guided imagery was similar to natural imagery with respect to sensory details, but similar to perceived memories with respect to reflective details.     

Age‐related changes in transient and oscillatory brain responses to auditory stimulation during early adolescence

Maturational changes in the capacity to process quickly the temporal envelope of sound have been linked to language abilities in typically developing individuals. As part of a longitudinal study of brain maturation and cognitive development during adolescence, we employed dense‐array EEG and spatiotemporal source analysis to characterize maturational changes in the timing of brain responses to temporal variations in sound. We found significant changes in the brain responses compared longitudinally at two time points in early adolescence, namely 10 years (65 subjects) and 11.5 years (60 of the 65 subjects), as well as large differences between adults, studied with the same protocol ( Poulsen, Picton & Paus, 2007 ), and the children at 10 and 11.5 years of age. The transient auditory evoked potential to tone onset showed decreases in the latency of vertex and T‐complex components, and a highly significant increase in the amplitude of the N1 wave with increasing age. The auditory steady state response to a 40‐Hz frequency‐modulated tone increased in amplitude with increasing age. The peak frequency of the envelope‐following response to sweeps of amplitude‐modulated white noise also increased significantly with increasing age. These results indicate persistent maturation of the cortical mechanisms for auditory processing from childhood into middle adulthood.     

Phenomenal characteristics associated with real and imagined events: the effects of event valence and absorption

This study examined the effects of emotional valence of an event and individual differences in absorption on the phenomenal characteristics associated with real and imagined events. Each participant described four events. Two of these were real and two were imagined, with one pleasant and stressful event being generated for each category. Pleasant events (both real and imagined) contained more detail (visual detail, smell, and taste, and more information regarding location, time, etc.) than stressful events. In addition, higher levels of absorption were related to higher ratings for both real and imagined events (for both pleasant and stressful events). Discussion focused on implications for further research in source monitoring and other relevant domains. Copyright © 1999 John Wiley & Sons, Ltd.     

Modality exclusivity norms for 400 nouns: The relationship between perceptual experience and surface word form

We present modality exclusivity norms for 400 randomly selected noun concepts, for which participants provided perceptual strength ratings across five sensory modalities (i.e., hearing, taste, touch, smell, and vision). A comparison with previous norms showed that noun concepts are more multimodal than adjective concepts, as nouns tend to subsume multiple adjectival property concepts (e.g., perceptual experience of the concept baby involves auditory, haptic, olfactory, and visual properties, and hence leads to multimodal perceptual strength). To show the value of these norms, we then used them to test a prediction of the sound symbolism hypothesis: Analysis revealed a systematic relationship between strength of perceptual experience in the referent concept and surface word form, such that distinctive perceptual experience tends to attract distinctive lexical labels. In other words, modality-specific norms of perceptual strength are useful for exploring not just the nature of grounded concepts, but also the nature of form–meaning relationships. These norms will be of benefit to those interested in the representational nature of concepts, the roles of perceptual information in word processing and in grounded cognition more generally, and the relationship between form and meaning in language development and evolution.     

Reply to Janine de Peyer’s “Traversing the Ineffable: Commentary on Sharon Farber’s ‘Becoming a Telepathic Tuning Fork’”

Janine de Peyer’s thoughtful and stimulating response to my paper evoked a good deal of thinking about playfulness and creativity in doing psychotherapy, what part intuition and empathy play in promoting telepathic communication, the distinction between thoughts and feelings unconsciously transmitted between people within close proximity and those transmitted across geographical distance, where there is no reliance on sensory clues involving sight, sound, smell, touch, and taste. De Peyer’s summary of research on telepathy tells us that most of the research tries to rule out the variable of unconscious sensory exchange by physically separating the “sender” from the “receiver.”

In her discussion of my paper, Janine de Peyer raises some very interesting questions about how telepathy is to be defined. I recall reading years ago about someone who had gone to a medium and heard some startling information about herself and those in her circle. As I wondered how the medium could know so much about someone she had never before met, it occurred to me that there was a lot of knowledge about a person conveyed by the brain-to-brain sensory cues, and this was not telepathic but more a function of intuition and empathy. I think that was true about the relationship I had with my patient. but as with the medium there was a lot of other information I received about her that did not depend on sensory cues, and that information was, I believe, conveyed telepathically. So yes, I say, to de Peyer’s (this issue) question, “Is it not worth differentiating between in-session heightened intuitive receptiveness, and unexplainable transmissions of affect/thoughts/information that traverse time and geographical space?” (p. 736, italics in the original). In considering the time spent in my patient’s physical presence, much of my empathic attunement originated from the intuitive response that was induced in me by her physical presence. I think the increasing empathic attunement laid the foundation for subsequent telepathic communication.     

Local and global cross-modal influences between vision and hearing, tasting, smelling, or touching

It is suggested that the distinction between global versus local processing styles exists across sensory modalities. Activation of one-way of processing in one modality should affect processing styles in a different modality. In 12 studies, auditory, haptic, gustatory or olfactory global versus local processing was induced, and participants were tested with a measure of their global versus local visual attention; the content of this measure was unrelated to the inductions. In a different set of 4 studies, the effect of local versus global visual processing on the way people listen to a poem or touch, taste, and smell objects was examined. In all experiments, global/local processing in 1 modality shifted to global/local processing in the other modality. A final study found more pronounced shifts when compatible processing styles were induced in 2 rather than 1 modality. Moreover, the study explored mediation by relative right versus left hemisphere activation as measured with the line bisection task and accessibility of semantic associations. It is concluded that the effects reflect procedural rather than semantic priming effects that occurred out of participants' awareness. Because global/local processing has been shown to affect higher order processing, future research may activate processing styles in other sensory modalities to produce similar effects. Furthermore, because global/local processing is triggered by a variety of real world variables, one may explore effects on other sensory modalities than vision. The results are consistent with the global versus local processing model, a systems account (GLOMOsys; F?rster & Dannenberg, 2010).     

Tactual perception: a review of experimental variables and procedures

This paper reviews the literature on tactual perception. Throughout this review, we will highlight some of the most relevant aspects in the touch literature: type of stimuli; type of participants; type of tactile exploration; and finally, the interaction between touch and other senses. Regarding type of stimuli, we will analyse studies with abstract stimuli such as vibrations, with two- and three-dimensional stimuli, and also concrete stimuli, considering the relation between familiar and unfamiliar stimuli and the haptic perception of faces. Under the "type of participants" topic, we separated studies with blind participants, studies with children and adults, and also performed an overview of sex differences in performance. The type of tactile exploration is explored considering conditions of active and passive touch, the relevance of movement in touch and the relation between haptic exploration and time. Finally, interactions between touch and vision, touch and smell and touch and taste are explored in the last topic. The review ends with an overall conclusion on the state of the art for the tactual perception literature. With this work, we intend to present an organised overview of the main variables in touch experiments, compiling aspects reported in the tactual literature, and attempting to provide both a summary of previous findings, and a guide to the design of future works on tactual perception and memory, through a presentation of implications from previous studies.     

Comparison of taste qualities elicited by tactile,electrical, and chemical stimulation of single human taste papillae

Taste quality responses elicited by chemical, electrical, and tactile stimulation of 40 single fungiform papillae in four subjects were examined. A comparison of responses revealed differences in taste quality mediation for the three different classes of stimuli. Chemical stimulation elicited multiple taste qualities from a greater proportion of papillae than did either electrical or tactile stimulation. In addition, the chemical data revealed the presence of consistent bitter-sour and sour-salty confusions. Both tactile and electrical stimulation elicited relatively few bitter and sweet responses, as compared with either sour or salty responses. However, correct quality identification in these papillae for bitter and sweet compounds was no different from that for sour or salty compounds. In addition, electrical stimulation elicited a greater proportion of salty responses than did tactile stimulation. Comparison of the taste quality elicited by either tactile or electrical stimulation of a papilla with the taste quality exhibiting the greatest relative chemical sensitivity in the papilla also revealed independence of responding, and it was observed that both electrical and tactile stimulation elicited consistent taste quality responses from papillae in which these taste qualities could not be elicited by any concentration of any chemical test compound. The observed differences in quality judgments are discussed as possibly being the result of cross-modal gustatory associations resulting from nongustatory components of inadequate stimulation.     

Psychophysical isolation of the modality responsible for detecting multimodal stimuli: a chemosensory example

Multiple sense modalities can be stimulated conjointly by a physically complex item, such as a predator, and also by a physically solitary stimulus that acts on multiple receptor classes. As a prime example of this latter group, l-menthol from mint stimulates taste, smell, and several somatosensory submodalities. In 6 experiments that used a variety of psychometric techniques, the authors experimentally isolated the modality by which l-menthol is detected in the upper airways (the nose and mouth). Interestingly, absolute detection in both the nasal and oral cavities was based on olfaction and not stinging, cooling, or taste. These experiments illustrate how the sensory modality responsible for detecting a multimodal or multisensory stimulus can be psychophysically isolated.

The perceived importance of sensory modalities in product usage: a study of self-reports

Although popular belief holds that vision dominates human experience, this does not necessarily imply that people regard vision as the most important sensory modality during the interaction with every product. Instead, the relative importance of the different modalities is likely to depend on the type of product and on the task performed. In Study 1, respondents reported how important they found vision, audition, touch, taste, and smell during the use of 45 different products. In Study 2, the respondents answered a similar question for the evaluation of the safety, ease of use, and enjoyment experienced for 15 products. Importance ratings for the sensory modalities differed considerably between the products. Differences due to the types of evaluations were smaller. Averaged over products and evaluation types, vision was the most important sensory modality for product evaluations, followed by touch, smell, audition, and taste. However, for about half of the individual products, the importance ratings for vision were lower than for one of the other modalities. These findings are in line with the view that vision is regarded the dominant modality, because it plays an important part in many and an irrelevant part in virtually no product experiences.     

Distinct and common cortical activations for multimodal semantic categories

If semantic representations are based on particular types of perceptual features, then category knowledge that arises from multimodal sensory experiences should rely on distinct and common sensory brain regions depending on the features involved. Using a similarity-based generation-andcomparison task, we found that semantic categories activated cortical areas associated with taste and smell, biological motion, and visual processing. Fruit names specifically activated medial orbitofrontal regions associated with taste and smell. Labels for body parts and clothing activated lateral temporal occipitoparietal areas associated with perceiving the human body. More generally, visually biased categories activated ventral temporal regions typically ascribed to visual object recognition, whereas functional categories activated lateral frontotemporal areas previously associated with the representation of usage properties. These results indicate that semantic categories that are distinguished by particular perceptual properties rely on distinct cortical regions, whereas semantic categories that rely on similar types of features depend on common brain areas.     

Expertise Shapes Multimodal Imagery for Wine

Although taste and smell seem hard to imagine, some people nevertheless report vivid imagery in these sensory modalities. We investigate whether experts are better able to imagine smells and tastes because they have learned the ability, or whether they are better imaginers in the first place, and so become experts. To test this, we first compared a group of wine experts to yoked novices using a battery of questionnaires. We show for the first time that experts report greater vividness of wine imagery, with no difference in vividness across sensory modalities. In contrast, novices had more vivid color imagery than taste or odor imagery for wines. Experts and novices did not differ on other vividness of imagery measures, suggesting a domain-specific effect of expertise. Critically, in a second study, we followed a group of students commencing a wine course and a group of matched control participants. Students and controls did not differ before the course, but after the wine course students reported more vivid wine imagery. We provide evidence that expertise improves imagery, exemplifying the extent of plasticity of cognition underlying the chemical senses.     

The psychophysics of imagery

A series of experiments considers the extent to which the interrelations among subjective magnitudes aroused by images corresponds to those for subjective magnitudes aroused by physical stimuli. In Experiment 1,68 undergraduates typed phrases in response to graded categories regarding the imagined magnitude of lights, sounds, and smells. In Experiment 2,5 undergraduates and, in Experiment 3, 3 graduate students then magnitude estimated the image intensity aroused by each of these stimulus phrases. In Experiments 4 and 5, the same subjects performed cross-modality matches between phrases arousing images for different attributes (light, sound, and smell). Statistical analysis indicates that estimates based on images display many of the same patterns as those based on physical stimuli. The major exception involves sequence effects, present for actual stimuli but not for images.     

Response bias in category and magnitude estimation of difference and similarity for loudness and pitch

Interval scales of sensory magnitude were derived from magnitude and category estimates of loudness differences, loudness similarities, pitch differences, and pitch similarities. In each of the four loudness experiments, a loudness scale was constructed from a nonmetric analysis of the rank order of the judgments. The four loudness scales so constructed were found to be equivalent to one another and indicated that loudness was a power function of sound pressure with an exponent of .29. A similar analysis for the four pitch experiments found the pitch scales derived in each case to be equivalent to one another and linear with the mel scale of pitch. Thus the same sensory and similarities for two distinct perceptual continua. For both pitch and loudness, these sensory scales were used to generate scales of sensory differences. A comparison of the category and magnitude estimates of sensory differences with the scale of sensory differences derived from the nonmetric analyses indicated the presence of significant response biases in both category and magnitude estimation procedures.
