Fulltext How high-intensity sensory consumption fills up resource scarcity: The boundary condition of self-acceptance

Peng L, Peng Y, Luo H, Deng Y

PLoS One, 2023;18(5):e0285853.
PMID: 37235592 DOI: 10.1371/journal.pone.0285853

OBJECTIVE: Everyone in life will experience resource scarcity, which causes self-discrepancy. It is widely known that individuals participate in reactive consumption to solve the problems of self-discrepancy and resources scarcity. This kind of consumption may be symbolically related to the essence of the resource scarcity or may occur in an unrelated domain. This study proposes a theory for "filling up" one's resource scarcity through high-intensity sensory consumption (HISC).
METHODS: We used different methods, including one-way analysis of variance (ANOVA), linear regression, mediating effect, and moderating effect, to test the four hypotheses. Four experiments in the study were conducted from May 2022 and August 2022 and involved undergraduates from a university and volunteers recruited online. All participants are adults and verbally agree to participate voluntarily. Study 1a (N = 96 (male 47, female 49), participants from a business school in China) measured resource scarcity in the laboratory experiments and verified the effect of resource scarcity on consumer HISC preference by using linear regression (H1). Study 1b (N = 191 (male 98, female 93), students and teachers from a university in China) measured resource scarcity in the laboratory experiments and manipulated positively and negatively valenced experiences. Using the PROCESS SPSS Mode l, we verified that negatively valenced stimuli also lead to higher levels of arousal, which in turn restores the self-discrepancy caused by resource scarcity (H2). Study 2 (an online experiment, N = 182 (male 91, female 91), participants from China) manipulated the resource scarcity in a color sensory stimulant context, replicating the preliminary effect and examined the mediating effect of the self-worth by using the PROCESS SPSS Mode 4 (H3). Study 3 (an online experiment, N = 251 (male 125, female 126), participants from China) manipulated resource scarcity and self-acceptance in the tactile sensory experience, and tested the moderating effect of self-acceptance by using the PROCESS SPSS Mode 8 (H4).
RESULTS: Four studies suggest that not only do individuals facing resources scarcity prefer HISC but also that this consumption is mediated and moderated by self-worth and self-acceptance, respectively. This preference for HISC is negated when individuals have high self-acceptance traits. The findings are tested in the auditory domain (as evidenced by a propensity for louder volume), the visual domain (as evidenced by a propensity for more intense colors), and the tactile domain (as evidenced by a propensity for more intense need for touch). The findings also demonstrate that individual preferences for HISC is shown to operate regardless of the valence (positive valence vs. negative valence) of the sensory consumption.
CONCLUSIONS: Across four experiments, we find that individuals who are subjected to resource scarcity show a preference for high-intensity sensory consumption in the auditory, visual, and tactile domains. We also find that both negatively and positively valenced sensory stimuli have the same impact on resource-scarce individuals' preference for HISC. Furthermore, we demonstrate that the sense of self-worth significantly mediates the effect of resource scarcity on HISC. Finally, we reveal that self-acceptance moderates the effect of resource scarcity on HISC preference.

Development of haptic based piezoresistive artificial fingertip: Toward efficient tactile sensing systems for humanoids

TermehYousefi A, Azhari S, Khajeh A, Hamidon MN, Tanaka H

Mater Sci Eng C Mater Biol Appl, 2017 Aug 01;77:1098-1103.
PMID: 28531983 DOI: 10.1016/j.msec.2017.04.040

Haptic sensors are essential devices that facilitate human-like sensing systems such as implantable medical devices and humanoid robots. The availability of conducting thin films with haptic properties could lead to the development of tactile sensing systems that stretch reversibly, sense pressure (not just touch), and integrate with collapsible. In this study, a nanocomposite based hemispherical artificial fingertip fabricated to enhance the tactile sensing systems of humanoid robots. To validate the hypothesis, proposed method was used in the robot-like finger system to classify the ripe and unripe tomato by recording the metabolic growth of the tomato as a function of resistivity change during a controlled indention force. Prior to fabrication, a finite element modeling (FEM) was investigated for tomato to obtain the stress distribution and failure point of tomato by applying different external loads. Then, the extracted computational analysis information was utilized to design and fabricate nanocomposite based artificial fingertip to examine the maturity analysis of tomato. The obtained results demonstrate that the fabricated conformable and scalable artificial fingertip shows different electrical property for ripe and unripe tomato. The artificial fingertip is compatible with the development of brain-like systems for artificial skin by obtaining periodic response during an applied load.

Fulltext Tactile perception of pleasantness in relation to perceived softness

Pasqualotto A, Ng M, Tan ZY, Kitada R

Sci Rep, 2020 07 07;10(1):11189.
PMID: 32636415 DOI: 10.1038/s41598-020-68034-x

The sense of touch allows us to infer objects' physical properties, while the same input also produces affective sensations. These affective sensations are important for interpersonal relationships and personal well-being, which raises the possibility that tactile preferences are adapted to the characteristics of the skin. Previous studies examined how physical properties such as surface roughness and temperature influence affective sensations; however, little is known about the effect of compliance (physical correlate of softness) on pleasantness. Thus, we investigated the psychophysical link between softness and pleasantness. Pieces of human skin-like rubber with different compliances were pressed against participants' fingers. Two groups of participants numerically estimated the perceived magnitude of either pleasantness or softness. The perceived magnitude of pleasantness and softness both increased monotonically as a function of increasing object compliance, levelling off at around the end of the stimulus range. However, inter-subject variability was greater for pleasantness than for perceived softness, whereas the slope of the linear function fit to the magnitude estimates was steeper for softness than for pleasantness. These results indicate that object compliance is a critical physical determinant for pleasantness, whereas the effect of compliance on pleasantness was more variable among individuals than the effect on softness was.

Br Med J, 1950;1:908.

Among the losses sustained by the Institute for Medical Research in Malaya during the Japanese occupation were the portraits of several of the former directors. The loss is unfortunate, as we had hoped to make use of a fifty-year series of portraits for a historical rne'noir planned for the Institute's half-centenary this year. The missing portraits are those of Dr. Hamilton-Wright, M.D. (McGill), and Dr. Henry Fraser, M.D., M.R.C.P. Dr. Wright retired to America after leaving Malaya in 1903 and died in Washington, D.C., in 1917. Dr. Fraser was born, I believe, in Aberdeen. He retired from Malaya in 1916 to live in Scotland, where he died in 1930. I would be grateful to any of your readers who could put me in touch with surviving relatives.

Fulltext Low pH Water Impairs the Tactile Sense of the Postlarvae of the Giant Freshwater Prawn Macrobrachium rosenbergii

Kawamura G, Bagarinao T, Yong ASK, Noor SN, Lim LS

Trop Life Sci Res, 2018 Mar;29(1):103-112.
PMID: 29644018 MyJurnal DOI: 10.21315/tlsr2018.29.1.7

The effect of low pH on the tactile sense of Macrobrachium rosenbergii postlarvae was determined in the laboratory by means of two behavioural assays: shelter (netting) occupancy and jumping response to touch stimuli (taps) by a glass micropipette. The postlarvae were acclimated to pH 4, pH 5, pH 6 and pH 7.5 (control) in 45 L aquaria 5-7 d before the experiments. Shelter occupancy decreased with pH and was significantly lower at pH 4 and pH 5 than at pH 6 and in the control. The jumping response instantly followed a tap 93-98% of the time in the control, pH 6 and pH 5 treatments. However, the postlarvae showed significantly lower jumping response (65%) at pH 4, indicating an impaired tactile sense. Low pH 4-5 probably degrades the chitin of the sensory setae and inhibits the surface mechanoreceptors of the prawn postlarvae.

Affective Interpersonal Touch in Close Relationships: A Cross-Cultural Perspective

Sorokowska A, Saluja S, Sorokowski P, Frąckowiak T, Karwowski M, Aavik T, et al.

Pers Soc Psychol Bull, 2021 12;47(12):1705-1721.
PMID: 33615910 DOI: 10.1177/0146167220988373

Interpersonal touch behavior differs across cultures, yet no study to date has systematically tested for cultural variation in affective touch, nor examined the factors that might account for this variability. Here, over 14,000 individuals from 45 countries were asked whether they embraced, stroked, kissed, or hugged their partner, friends, and youngest child during the week preceding the study. We then examined a range of hypothesized individual-level factors (sex, age, parasitic history, conservatism, religiosity, and preferred interpersonal distance) and cultural-level factors (regional temperature, parasite stress, regional conservatism, collectivism, and religiosity) in predicting these affective-touching behaviors. Our results indicate that affective touch was most prevalent in relationships with partners and children, and its diversity was relatively higher in warmer, less conservative, and religious countries, and among younger, female, and liberal people. This research allows for a broad and integrated view of the bases of cross-cultural variability in affective touch.

MyJurnal

Surprisingly little was known about the importance of touch in life which was placed at a lower emphasis than the rest-namely visual, auditory, olfactory sense and etc. This writing aimed to decipher the significances of interpersonal touch, its culture, practices, barriers and challenges, which were then conveyed to the public as a form of health promotion. Methodology includes narrative review where the suitable literatures used were searched using ScienceDirect database under the keywords of “Interpersonal Touch”, “Oxytocin” and “Touch”. In this review, we have highlighted some of the most critical points which should have been promoted to the public. For example, touch satisfies individual psychosomatic and psychosocial needs. It forms a non-verbal communication culture which interacts about emotions, trust, compliance and more. Furthermore, it has been linked to the secretion of multifunctional bioactive chemical-oxytocin which was well-known in its therapeutic advantages for a wide range of commonest chronic diseases and social ills. Although some dysfunctional consequences may be resulted, incorporating genuine interpersonal touch into today’s efforts is undeniably viewed as a good option in solving many social problems.

Multisensory distortions of the hand have differential effects on tactile perception

Treshi-marie Perera A, Newport R, McKenzie KJ

Exp Brain Res, 2015 Nov;233(11):3153-61.
PMID: 26195170 DOI: 10.1007/s00221-015-4384-8

Research has suggested that altering the perceived shape and size of the body image significantly affects perception of somatic events. The current study investigated how multisensory illusions applied to the body altered tactile perception using the somatic signal detection task. Thirty-one healthy volunteers were asked to report the presence or absence of near-threshold tactile stimuli delivered to the index finger under three multisensory illusion conditions: stretched finger, shrunken finger and detached finger, as well as a veridical baseline condition. Both stretching and shrinking the stimulated finger enhanced correct touch detections; however, the mechanisms underlying this increase were found to be different. In contrast, the detached appearance reduced false touch reports-possibly due to reduced tactile noise, as a result of attention being directed to the tip of the finger only. These findings suggest that distorted representations of the body could have different modulatory effects on attention to touch and provide a link between perceived body representation and somatosensory decision-making.

Fulltext Advances in bio-tactile sensors for minimally invasive surgery using the fibre Bragg grating force sensor technique: a survey

Abushagur AA, Arsad N, Reaz MI, Bakar AA

Sensors (Basel), 2014;14(4):6633-65.
PMID: 24721774 DOI: 10.3390/s140406633

The large interest in utilising fibre Bragg grating (FBG) strain sensors for minimally invasive surgery (MIS) applications to replace conventional electrical tactile sensors has grown in the past few years. FBG strain sensors offer the advantages of optical fibre sensors, such as high sensitivity, immunity to electromagnetic noise, electrical passivity and chemical inertness, but are not limited by phase discontinuity or intensity fluctuations. FBG sensors feature a wavelength-encoding sensing signal that enables distributed sensing that utilises fewer connections. In addition, their flexibility and lightness allow easy insertion into needles and catheters, thus enabling localised measurements inside tissues and blood. Two types of FBG tactile sensors have been emphasised in the literature: single-point and array FBG tactile sensors. This paper describes the current design, development and research of the optical fibre tactile techniques that are based on FBGs to enhance the performance of MIS procedures in general. Providing MIS or microsurgery surgeons with accurate and precise measurements and control of the contact forces during tissues manipulation will benefit both surgeons and patients.

Fulltext The accuracy of mother's touch to detect fever in children: a systematic review

Teng CL, Ng CJ, Hanafi NS, Zailinawati AH, Tong SF

J Trop Pediatr, 2008 Feb;54(1):70-3.
PMID: 18039678 DOI: 10.1093/tropej/fmm077

Universally, mothers often use touching to detect fever in their children. We perform a systematic review of published diagnostic studies evaluating the ability of mothers to detect fever in their children by touching. We found 10 studies satisfying our inclusion criteria. The meta-analysis revealed a summary sensitivity of 89.2% and summary specificity of 50%-maternal touch is perhaps more useful to exclude fever rather than to 'rule in' fever. However, due to significant heterogeneity in the included studies, interpretation of the summary data is difficult.

Gender and national differences in attitudes toward same-gender touch

Willis FN, Rawdon VA

Percept Mot Skills, 1994 Jun;78(3 Pt 1):1027-34.
PMID: 8084675

Women have been reported to be more positive about same-gender touch, but cross-cultural information about this touch is limited. Male and female students from Chile (n = 26), Spain (n = 61), Malaysia (n = 32), and the US (n = 77) completed a same-gender touch scale. As in past studies, US women had more positive scores than US men. Malaysians had more negative scores than the other three groups. Spanish and US students had more positive scores than Chilean students. National differences in attitudes toward particular types of touch were also noted. The need for new methods for examining cross-cultural differences in touch was discussed.

Real-time and visual sensing devices based on pH-control assembled lanthanide-barium nano-cluster

Liu M, Li H, Bai L, Zheng K, Zhao Z, Chen Z, et al.

J Hazard Mater, 2021 07 05;413:125291.

Real-time and visual monitoring of pollutants in the air is of great importance since they are usually cannot be seen, smelled, or touched. Lanthanide nano-cluster is a kind of luminescent sensor for various species. However, controlling synthesis of lanthanide nano-cluster remains experimentally challenging. In this work, four series of lanthanide-barium (Ln-Ba) nano-clusters of Dy2Ba (1), Tb2Ba2 (2), Ln4Ba3 (Ln = Tb, 3a; Eu, 3b), Tb4Ba4 (4) were assembled through precisely controlling the pH of the reactant solutions. The work features the first example that the number of cluster's nuclei changes regularly with the pH. Moreover, investigation reveals that nano-cluster 3a is a highly selective and sensitive sensor towards acetylacetone (acac) and aniline. Interestingly, easy-to-use sensing devices of test paper, agarose gel, and five kinds of film on CaCO3, polyfoam, coin, mask, and wall that based on 3a were fabricated by facile methods. The seven sensing devices showed remarkable ability to sense aniline and acac vapors with visibility to the naked eyes. This is the first work on multiple real-time and visual sensing devices based on the lanthanide nano-cluster.

Multisensory stimulation modulates perceptual and post perceptual face representations: Evidence from event-related potentials

Estudillo AJ, Kaufmann JM, Bindemann M, Schweinberger SR

Eur J Neurosci, 2018 09;48(5):2259-2271.
PMID: 30107052 DOI: 10.1111/ejn.14112

Seeing a face being touched in spatial and temporal synchrony with the own face produces a bias in self-recognition, whereby the other face becomes more likely to be perceived as the self. The present study employed event-related potentials to explore whether this enfacement effect reflects initial face encoding, enhanced distinctiveness of the enfaced face, modified self-identity representations, or even later processing stages that are associated with the emotional processing of faces. Participants were stroked in synchrony or asynchrony with an unfamiliar face they observed on a monitor in front of them, in a situation approximating a mirror image. Subsequently, event-related potentials were recorded during the presentation of (a) a previously synchronously stimulated face, (b) an asynchronously stimulated face, (c) observers' own face, (d) filler faces, and (e) a to-be-detected target face, which required a response. Observers reported a consistent enfacement illusion after synchronous stimulation. Importantly, the synchronously stimulated face elicited more prominent N170 and P200 responses than the asynchronously stimulated face. By contrast, similar N250 and P300 responses were observed in these conditions. These results suggest that enfacement modulates early neural correlates of face encoding and facial prototypicality, rather than identity self-representations and associated emotional processes.

PMID: 25606132 MyJurnal

A twin registry is a registry of twin pairs (monozygotic = MZ and Dizygotic = DZ) who are willing to consider participating in health-related research. Twins are able to help researchers study the impact of genetic and environmental factors on health and the treatment and prevention of disease in a special way. Throughout the world, twin registries have been established by the governments via the National Health and Medical Research in order to put researchers in touch with twins who might be willing to take part in particular projects. In Australia, for example, more than 30,000 pairs of twins have joined the registry, making it the largest volunteer registry of its kind in the world. However, in some countries such as Denmark, the first twin registry was born in a medical faculty and it was then expanded to the National Twin Registry of Denmark. (Copied from article).

The utilization of parallelogram structure in a small-sized humanoid robot consists of two parallel platforms that are linked serially in each leg. The thigh and shank of each leg consists of two servomotors as actuator and linked in parallel platform. By using parallel mechanism in leg structure, foot sole surface is always parallel to the walking surface at any point. Even it looks unnatural to human-like walking motion, the expected result is the robot can maintain it posture while walking and at the point foot sole touch the walking surface, unnecessary vibrates can be modulated at the certain level to remain its balance. The effectiveness and the performance of the proposed parallel platforms are experimented by using zero moment point (ZMP) method by taking various scenario data from pressure sensors attached at the footsole. Planned walking gait is introduced to be identical in terms of foot steps length and width of each leg swing. As the results, in terms of load in each actuator, required torque at servomotors can be reduced because two servomotors are used simultaneously in one parallel system. Stable walking gait can be predicted as the quantity of error falls within the error ranges from the published walking gait patterns.

Fulltext Exposure to foods' non-taste sensory properties. A nursery intervention to increase children's willingness to try fruit and vegetables

Dazeley P, Houston-Price C

Appetite, 2015 Jan;84:1-6.
PMID: 25218879 DOI: 10.1016/j.appet.2014.08.040

Activities that engage young children with the sensory properties of foods are popular with nursery schools, despite the lack of evidence for their efficacy in increasing children's consumption of healthy foods. This study provides the first empirical exploration of the effectiveness of a non-taste sensory activity program in a nursery school setting. Ninety-two children aged between 12 and 36 months were allocated either to an intervention group, who took part in looking, listening, feeling and smelling activities with unusual fruits and vegetables every day for 4 weeks, or to a non-intervention control group. In a subsequent mealtime taste test, children touched and tasted more of the vegetables to which they had been familiarized in their playtime activities than of a matched set of non-exposed foods. The results demonstrate that hands-on activities with unfamiliar fruits and vegetables can enhance children's willingness to taste these foods, and confirm the potential for such activities to support healthy eating initiatives.

Conceptual Design of Haptic-Feedback Navigation Device for Individuals with Alzheimer's Disease

Che Me R, Biamonti A, Mohd Saad MR

Stud Health Technol Inform, 2015;217:195-203.
PMID: 26294473

Wayfinding ability in older adults with Alzheimer's disease (AD) is progressively impaired due to ageing and deterioration of cognitive domains. Usually, the sense of direction is deteriorated as visuospatial and spatial cognition are associated with the sensory acuity. Therefore, navigation systems that support only visual interactions may not be appropriate in case of AD. This paper presents a concept of wearable navigation device that integrates the haptic-feedback technology to facilitate the wayfinding of individuals with AD. The system provides the simplest instructions; left/right using haptic signals, as to avoid users' distraction during navigation. The advantages of haptic/tactile modality for wayfinding purpose based on several significant studies are presented. As preliminary assessment, a survey is conducted to understand the potential of this design concept in terms of (1) acceptability, (2) practicality, (3) wearability, and (4) environmental settings. Results indicate that the concept is highly acceptable and commercially implementable. A working prototype will be developed based on the results of the preliminary assessment. Introducing a new method of navigation should be followed by continuous practices for familiarization purpose. Improved navigability allows the good performance of activities of daily living (ADLs) hence maintain the good quality of life in older adults with AD.
