Triggering Events

Past research has shown that merely anticipating a certain action in someone else leads observers to engage in the anticipated action—a phenomenon called anticipated action. In a standard experiment on anticipated action, participants watch video clips of a model engaging in triggering events such as nose wrinkling or hair falling. A typical finding is that when observing nose wrinkling, participants engage in more nose scratching actions than hair stroking actions and vice versa for observing hair falling. While past research suggested that this effect is due to inferring a desire in others to act, an alternative explanation is that observing a triggering event in someone else guides attention towards respective body parts facilitating any action towards this body part. In two experiments we set this explanation to a critical test. The results speak against attention as driving process and in favor of inferring a desire in others to act, because guiding attention to the location of the triggering event did not result in anticipated action effects. This result has important implications for research on anticipative processes and imitative behavior.

The Impact

The objective of this case study was to experimentally manipulate the impact on arousal and recall of two characteristics frequently occurring in gruesome depictions of body parts in smoking cessation advertisements: the presence or absence of an external physical insult to the body part depicted; whether or not the image contains a clear figure/ground demarcation. Three hundred participants (46% male, 54% female; mean age 27.3 years, SD = 11.4) participated in a two-stage online study wherein they viewed and responded to a series of gruesome 4-s video images. Seventy-two video clips were created to provide a sample of images across the two conditions: physical insult versus no insult and clear figure/ground demarcation versus merged or no clear figure/ground demarcation. In stage one, participants viewed a randomly ordered series of 36 video clips and rated how “confronting” they considered each to be. Seven days later (stage two), to test recall of each video image, participants viewed all 72 clips and were asked to identify those they had seen previously. Images containing a physical insult were consistently rated more confronting and were remembered more accurately than images with no physical insult. Images with a clear figure/ground demarcation were rated as no more confronting but were consistently recalled with greater accuracy than those with unclear figure/ground demarcation. Makers of gruesome health warning television advertisements should incorporate some form of physical insult and use a clear figure/ground demarcation to maximize image recall and subsequent potential advertising effectiveness.

This chapter discusses body part nouns, a part of language that is central to human life, and the polysemy that arises in connection with them. Examples from everyday speech and narrative in various contexts are examined in a Papuan language called Koromu and semantic characteristics of body part nouns in other studies are also considered. Semantic templates are developed for nouns that represent highly visible body parts: for example, wapi ‘hands/arms’, ehi ‘feet/legs’, and their related parts. Culture-specific explications are expressed in a natural metalanguage that can be translated into Koromu to avoid the cultural bias inherent in using other languages and to reveal both distinctive semantic components and similarities to cross-linguistic examples.

AbstractThe representation of the metrics of the hands is distorted, but is susceptible to malleability due to expert dexterity (magicians) and long-term tool use (baseball players). However, it remains unclear whether modulation leads to a stable representation of the hand that is adopted in every circumstance, or whether the modulation is closely linked to the spatial context where the expertise occurs. To this aim, a group of 10 experienced Sign Language (SL) interpreters were recruited to study the selective influence of expertise and space localisation in the metric representation of hands. Experiment 1 explored differences in hands’ size representation between the SL interpreters and 10 age-matched controls in near-reaching (Condition 1) and far-reaching space (Condition 2), using the localisation task. SL interpreters presented reduced hand size in near-reaching condition, with characteristic underestimation of finger lengths, and reduced overestimation of hands and wrists widths in comparison with controls. This difference was lost in far-reaching space, confirming the effect of expertise on hand representations is closely linked to the spatial context where an action is performed. As SL interpreters are also experts in the use of their face with communication purposes, the effects of expertise in the metrics of the face were also studied (Experiment 2). SL interpreters were more accurate than controls, with overall reduction of width overestimation. Overall, expertise modifies the representation of relevant body parts in a specific and context-dependent manner. Hence, different representations of the same body part can coexist simultaneously.

AbstractSeveral functional magnetic resonance imaging (fMRI) studies have demonstrated that resting-state brain activity consists of multiple components, each corresponding to the spatial pattern of brain activity induced by performing a task. Especially in a movement task, such components have been shown to correspond to the brain activity pattern of the relevant anatomical region, meaning that the voxels of pattern that are cooperatively activated while using a body part (e.g., foot, hand, and tongue) also behave cooperatively in the resting state. However, it is unclear whether the components involved in resting-state brain activity correspond to those induced by the movement of discrete body parts. To address this issue, in the present study, we focused on wrist and finger movements in the hand, and a cross-decoding technique trained to discriminate between the multi-voxel patterns induced by wrist and finger movement was applied to the resting-state fMRI. We found that the multi-voxel pattern in resting-state brain activity corresponds to either wrist or finger movements in the motor-related areas of each hemisphere of the cerebrum and cerebellum. These results suggest that resting-state brain activity in the motor-related areas consists of the components corresponding to the elementary movements of individual body parts. Therefore, the resting-state brain activity possibly has a finer structure than considered previously.

Abstract In this paper I provide a description of the role of body-part terms in expressions of emotion and other semantic extensions in MalakMalak, a non-Pama-Nyungan language of the Daly River area. Body-based expressions denote events, emotions, personality traits, significant places and people and are used to refer to times and number. Particularly central in the language are men ‘stomach’, pundu ‘head’ and tjewurr ‘ear’ associated respectively with basic emotions, states of mind and reason. The figurative extensions of these body parts are discussed systematically, and compared with what is known for other languages of the Daly River region. The article also explores the grammatical make up of body-based emotional collocations, and in particular the role of noun incorporation. In MalakMalak, noun incorporation is a central part of forming predicates with body parts, but uncommon in any other semantic domain of the language and only lexemes denoting basic emotions may also incorporate closed-class adjectives.

Phenotypic variances within pairs of monozygotic and dizygotic twin heifers and also genetic variances and heritabilities were calculated for 12 linear body measurements at a sequence of eight ages up to two years old. The 60 pairs of fraternal and 60 pairs of identical twins used were reared as part of a larger uniformity trial in which feeding was effectively ad libitum throughout.Size differences between members of DZ twin pairs were found to be approximately normally distributed with about the same variance for all breeds and crosses. The variance within DZ pairs increased strongly with age, with a marked increase between 9 and 12 months of age and with most body measurements showing a broadly similar trend. On a logarithmic scale DZ variances increased roughly linearly with degree of maturity and at about the same rate in each body measurement. Coefficients of variation within DZ pairs corrected for measuring error had an average value of 2%. They did not change greatly with age, and were roughly the same for most body measurements although width measurements tended to be more variable than average.Coefficients of variation within MZ pairs had a corresponding overall average of 1·4%; they declined rapidly with age from 2·0% to 1·1%, were roughly the same for all body measurements, but at early ages tended to be greater in late than in early maturing body parts. However, they showed no association with the earliness of maturing of a body part provided variation was measured at the same degree of maturity for each body part.Genetic variation increased rapidly with age in all body measurements. The rate of increase with age was greater for late than for early maturing parts. The rate of increase with degree of maturity, however, was about the same for all body measurements. Coefficients of genetic variation increased slowly with age; they had an average value of 1·6%.Estimates of heritability are given at a sequence of eight ages for each of 12 body measurements. They increased strongly with age from 0·14 on average at three months of age to 0·67 on average at two years of age. At any fixed age, early maturing body parts tended to have higher heritabilities than later maturing body parts. However, if heritability was measured at the same degree of maturity in each body part, early and late maturing parts had about equal heritabilities.The present results are compared with those obtained from twin cattle studies in New Zealand, Sweden and Wisconsin, U.S.A.Inferences from twins about genetic variances and heritabilities for unrelated animals are discussed.

Shift Hypothesis

Visual attention in complex, dynamic scenes is attracted to locations that contain socially-relevant features, such as faces, and to areas that are visually salient. Previous work suggests that there is a global shift over development such that observers increasingly attend to faces with age. However, no prior work has tested whether this shift is truly global, that is, consistent across and within stimuli despite variations in content. To test the global shift hypothesis, we recorded eye movements of 89 children (6 months to 10 years) and adults while they viewed seven video clips. We measured the extent to which each participant attended to faces and to salient areas for each video. There was no evidence of global age-related changes in attention: Neither feature showed consistent increases or decreases with age. Moreover, windowed analyses within each stimulus video revealed moment-to-moment variations in the relation between age and each visual feature. For some time windows, adults looked more often at both feature types compared to infants and children. However, for other time windows the pattern was reversed—younger participants looked more at faces and salient locations. Lack of consistent directional effects provides strong evidence against the global shift hypothesis. We suggest an alternative explanation: Over development, observers increasingly prioritize when and where to look by learning to track which features are relevant within a scene. Implications for the development of visual attention and children’s understanding of screen-based media are discussed.

Multi-modality is an important feature of sensor based activity recognition. In this work, we consider two inherent characteristics of human activities, the spatially-temporally varying salience of features and the relations between activities and corresponding body part motions. Based on these, we propose a multi-agent spatial-temporal attention model. The spatial-temporal attention mechanism helps intelligently select informative modalities and their active periods. And the multiple agents in the proposed model represent activities with collective motions across body parts by independently selecting modalities associated with single motions. With a joint recognition goal, the agents share gained information and coordinate their selection policies to learn the optimal recognition model. The experimental results on four real-world datasets demonstrate that the proposed model outperforms the state-of-the-art methods.

Comparative Results

Body parts are typical, most material-intensive and expensive parts. When repairing worn out hull details, the costs for repairing equipment are significantly reduced, in comparison with the manufacture of new ones, the consumption of metal, electricity, and environmental pollution is reduced. Unlike many other methods, the methods of restoring body parts with polymeric materials are technologically simple, do not require large energy inputs and high qualification of the personnel. Due to the polymer layer, the stresses in the contact zone of loaded bodies with the bearing raceways decrease and its durability increases, there is no fretting corrosion and the service life of the bearing and body part increases manyfold. The use of polymeric composites can significantly improve the efficiency of restoring body parts. This is due to increased thermal conductivity, thermal and heat resistance, lower cost of composites in comparison with non-filled polymers. A promising direction in improving the consumer properties of the material is the filling of the polymer matrix with nanoscale particles. The nanocomposite based on elastomer F-40 filled with aluminum and copper nanoparticles has been developed and thoroughly studied at the LSTU. The material is designed to restore the landing holes in the hull parts of the tractor equipment. The article presents the results of experimental studies and analysis of deformation-strength and adhesion properties of a nanocomposite, its optimal composition is justified. Comparative results of the study of heat resistance and thermal stability of the F-40 elastomer and a nanocomposite based on are presented. It is shown that the nanocomposite has higher consumer properties than the F-40 elastomer: the strength and endurance are increased to 1.3 times, the heat resistance is up to 123C, the aging coefficients are 1.8 times higher in strength, 1.4 times in deformation.

Intra-hemispheric interference has been often observed when body parts with neighboring representations within the same hemisphere are stimulated. However, patterns of interference in early and late somatosensory processing stages due to the stimulation of different body parts have not been explored. Here, we explore functional similarities and differences between attention modulation of the somatosensory N140 and P300 elicited at the fingers vs. cheeks. In an active oddball paradigm, 22 participants received vibrotactile intensity deviant stimulation either ipsilateral (within-hemisphere) or contralateral (between-hemisphere) at the fingers or cheeks. The ipsilateral deviant always covered a larger area of skin than the contralateral deviant. Overall, both N140 and P300 amplitudes were higher following stimulation at the cheek and N140 topographies differed between fingers and cheek stimulation. For the N140, results showed higher deviant ERP amplitudes following contralateral than ipsilateral stimulation, regardless of the stimulated body part. N140 peak latency differed between stimulated body parts with shorter latencies for the stimulation at the fingers. Regarding P300 amplitudes, contralateral deviant stimulation at the fingers replicated the N140 pattern, showing higher responses and shorter latencies than ipsilateral stimulation at the fingers. For the stimulation at the cheeks, ipsilateral deviants elicited higher P300 amplitudes and longer latencies than contralateral ones. These findings indicate that at the fingers ipsilateral deviant stimulation leads to intra-hemispheric interference, with significantly smaller ERP amplitudes than in contralateral stimulation, both at early and late processing stages. By contrast, at the cheeks, intra-hemispheric interference is selective for early processing stages. Therefore, the mechanisms of intra-hemispheric processing differ from inter-hemispheric ones and the pattern of intra-hemispheric interference in early and late processing stages is body-part specific.
