Cultural and sex differences in touch avoidance

Touch Avoidance with Close People and Strangers: Effects of Gender, Sexual Orientation, and Relationship Status

Human contact through physical touch is a core element in social bonding, which facilitates psychosocial well-being. Touch avoidance is an individual disposition that may prevent individuals from engaging in or benefiting from physical touch. The present study recruited 450 Italian participants (51.1% female) with a mean age of 32.2 ± 13.5 to complete a battery of demographic questionnaires and the Touch Avoidance Questionnaire (TAQ). Individuals who were single and reporting same-sex attraction avoided touch with family more often than their coupled counterparts or those reporting opposite-sex attraction. Moreover, males reporting same-sex attraction avoided touch with a potential partner more frequently. When comparing sex differences, women reported greater touch avoidance with opposite-sex friends more frequently, while males avoided touch with same-sex friends more frequently. Individuals reporting opposite-sex attraction reported greater touch amongst same-sex friends. Single males avoided touch with same-sex friends more frequently than those in a relationship. Overall, this contribution reflects the individual differences related to social touch avoidance with respect to sex, relationship status, and sexual orientation in an Italian sample.

Teachers’ Concerns Regarding Touching Their Students in the Classroom: A Scale Development Study

This study details the development of the “Classroom Touch Concern Scale” (CTC), which was designed to measure individual differences among teachers regarding their feelings of concern when touching students in the classroom. The CTC incorporates two correlated dimensions: CTC associated with touching students of the same gender and CTC associated with touching students of a different gender. Studies 1 through 7 used various samples of university faculty and high school teachers to investigate the CTC with regard to item development, dimensionality, construct validity, linguistic validity, predictive validity, discriminant validity, and convergent validity. The results showed that the CTC has high internal consistency reliability and an acceptable to good construct validity, a good discriminant and convergent validity, linguistic validity, and predictive validity. We discuss the practical implications and limitations of using the CTC.

Psychology of the Embrace: How Body Rhythms Communicate the Need to Indulge or Separate

In the context of embodiment research, there has been a growing interest in phenomena of interpersonal resonance. Given that haptic communication is particularly under-researched, we focused on the phenomenon of embracing. When we embrace a dear friend to say good-bye at the end of a great evening, we typically first employ smooth and yielding movements with round transitions between muscular tensing and relaxing (smooth, indulging rhythms), and when the embrace is getting too long, we start to use slight patting (sharp, fighting rhythms with sharp transitions) on the back or the shoulders of the partner in order to indicate that we now want to end the embrace. On the ground of interpersonal resonance, most persons (per-sonare, latin = to sound through) understand these implicit nonverbal signals, expressed in haptic tension-flow changes, and will react accordingly. To experimentally test the hypothesis that smooth, indulgent rhythms signal the wish to continue, and sharp, fighting rhythms signal the wish to separate from an embrace, we randomly assigned 64 participants, all students at the University of Heidelberg, to two differently sequenced embrace conditions: (a) with the fighting rhythm at the end of the sequence of two indulgent rhythms (Sequence A: smooth-smooth-sharp); and (b) with the fighting rhythm between two indulgent rhythms (Sequence B: smooth-sharp-smooth). Participants were embraced for 30 s by a female confe-derate with their eyes blindfolded to focus on haptic and kinesthetic cues without being distracted by visual cues. They were instructed to let go of a handkerchief that they held between the fingers of their dominant hand during the embrace, when they felt that the embracer signaled the wish to finish the embrace. Participants significantly more often dropped the handkerchief in the phase of the fighting rhythm, no matter in which location it occurred in the embrace sequence. We assume that we learn such rhythmic behaviors and their meaning from the beginning of life in the communication with caregivers and meaningful others. Some are universal and some are quite idiosyncratic. Infants seem to be highly sensitive to the dynamic nuances presented to them, demonstrating a high capacity for embodied resonance and a high behavioral plasticity. Such adaptive mechanisms are assumed to lay the foundations of family culture (including the degree to which nonverbal cues are attended to, the communication of taboos, etc.) and larger culture, and may also play an important role in interpersonal attraction and aesthetic experience.

Gender and National Differences in Attitudes toward Same-Gender Touch

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.

An Exploration of the Interaction Between Touch Avoidance and the Pleasant Touch (C-Tactile Afferent) System

C-tactile (CT) afferent fibers are optimally stimulated by slow gentle stroking, and an inverted U-shaped relationship exists between stroking velocity and pleasantness ratings of this type of touch. This study investigated whether an additional and potentially important variable, touch avoidance, interacts with this relationship. While a typical U-shaped velocity–pleasantness relationship was expected, those high in touch avoidance were expected to rate CT-targeted touch (1–10 cm/s) as less pleasant than those low in touch avoidance. Thirty-five participants rated the pleasantness of a brush stroked across their forearm at five velocities (0.3, 1, 3, 10, 30 cm/s) administered by a custom-built touch stimulator (“the touch device”). Participants also completed two self-report measures of touch avoidance. There was an inverted U-shaped relationship between velocity and pleasantness ratings, and high touch avoidance resulted in a downward shift of this curve. The downward shift was across all velocities, including those that do not maximally engage CT afferents. It appears that touch avoidance reduces the pleasantness of all kinds of touch in a similar way, and it is unlikely to be specifically related to CT afferent functioning. Other potential mechanisms leading to touch avoidance are discussed.

Assessing Individual Differences in the Need for Interpersonal Touch and Need for Touch

The present study investigates individual differences in the automatic use of haptic information from interpersonal touch. We present a questionnaire assessing individual differences in the need for interpersonal touch (NFIPT), which was validated within an unrelated product-evaluation task. Before entering the laboratory, participants were briefly touched on the shoulder or received no touch. Assessing confidence and frustration within the following product-evaluation task, we examined moderating effects of NFIPT and additionally effects of need for touch (NFT). Results showed that higher NFIPT participants were more confident when they were briefly touched. Effects on frustration were only found for NFT. Results show that frustration was greater for individuals with higher NFT, when they could not touch the product during the evaluation task.

Squeeze me, but don't tease me: human and mechanical touch enhance visual attention and emotion discrimination

Being touched by another person influences our readiness to empathize with and support that person. We asked whether this influence arises from somatosensory experience, the proximity to the person and/or an attribution of the somatosensory experience to the person. Moreover, we were interested in whether and how touch affects the processing of ensuing events. To this end, we presented neutral and negative pictures with or without gentle pressure to the participants' forearm. In Experiment 1, pressure was applied by a friend, applied by a tactile device and attributed to the friend, or applied by a tactile device and attributed to a computer. Across these conditions, touch enhanced event-related potential (ERP) correlates of picture processing. Pictures elicited a larger posterior N100 and a late positivity discriminated more strongly between pictures of neutral and negative content when participants were touched. Experiment 2 replicated these findings while controlling for the predictive quality of touch. Experiment 3 replaced tactile contact with a tone, which failed to enhance N100 amplitude and emotion discrimination reflected by the late positivity. This indicates that touch sensitizes ongoing cognitive and emotional processes and that this sensitization is mediated by bottom-up somatosensory processing. Moreover, touch seems to be a special sensory signal that influences recipients in the absence of conscious reflection and that promotes prosocial behavior.

"Artificial humans": Psychology and neuroscience perspectives on embodiment and nonverbal communication

"Artificial humans", so-called "Embodied Conversational Agents" and humanoid robots, are assumed to facilitate human-technology interaction referring to the unique human capacities of interpersonal communication and social information processing. While early research and development in artificial intelligence (AI) focused on processing and production of natural language, the "new AI" has also taken into account the emotional and relational aspects of communication with an emphasis both on understanding and production of nonverbal behavior. This shift in attention in computer science and engineering is reflected in recent developments in psychology and social cognitive neuroscience. This article addresses key challenges which emerge from the goal to equip machines with socio-emotional intelligence and to enable them to interpret subtle nonverbal cues and to respond to social affordances with naturally appearing behavior from both perspectives. In particular, we propose that the creation of credible artificial humans not only defines the ultimate test for our understanding of human communication and social cognition but also provides a unique research tool to improve our knowledge about the underlying psychological processes and neural mechanisms.

Social anxiety and response to touch: incongruence between self-evaluative and physiological reactions

Touch is an important form of social interaction, and one that can have powerful emotional consequences. Appropriate touch can be calming, while inappropriate touch can be anxiety provoking. To examine the impact of social touching, this study compared socially high-anxious (N=48) and low-anxious (N=47) women's attitudes concerning social touch, as well as their affective and physiological responses to a wrist touch by a male experimenter. Compared to low-anxious participants, high-anxious participants reported greater anxiety to a variety of social situations involving touch. Consistent with these reports, socially anxious participants reacted to the experimenter's touch with markedly greater increases in self-reported anxiety, self-consciousness, and embarrassment. Physiologically, low-anxious and high-anxious participants showed a distinct pattern of sympathetic-parasympathetic coactivation, as reflected by decreased heart rate and tidal volume, and increased respiratory sinus arrhythmia, skin conductance, systolic/diastolic blood pressure, stroke volume, and respiratory rate. Interestingly, physiological responses were comparable in low and high-anxious groups. These findings indicate that social anxiety is accompanied by heightened aversion towards social situations that involve touch, but this enhanced aversion and negative-emotion report is not reflected in differential physiological responding.

Some touching situations: the relationship between gender and contextual variables in cardiovascular responses to human touch

This study examined how cardiovascular reactivity to human touch is affected by the social context of the situation. Context for a ten-second touch was manipulated for 61 male and 64 female undergraduate participants in three ways: professional touch, were participants were touched on the wrist to have their pulse taken; social touch, an unexplained touch to the same area of the arm; and a no-touch control, where participants were told their pulse was being taken automatically without being touched. Social context was also manipulated by employing both same-sex and opposite-sex touch experimenters. In the professional touch and no-touch conditions, participants' heart rate and blood pressure decreased overall; however, in the social touch condition initial increases were observed for both measures. Female experimenters produced greater heart rate decreases than male experimenters. The greatest cardiovascular increases were found with women being touched by men in the social condition. These data suggest that both context and gender are important contextual factors in determining cardiovascular reactivity.

The right to touch and be touched

Touching is an integral part of human behaviour; from the moment of birth until they die, people need to be touched and to touch others. Touching is an intimate action that implies an invasion of the individual's personal, private space. In ethical terms, the question of touching is closely related to the patient's right to integrity and inviolability. The purpose of this study was to describe touching as it is experienced by elderly patients and nurses in long-term care. Touching was approached as a form of communication and as an important part of nursing practice. The participants, 25 patients and 30 nurses, were interviewed using a semistructured schedule. The data were analysed using the method of content analysis. The patients experienced touching by nurses as gentle, comforting and important. The nurses, for their part, experienced touching by patients as easy and natural. The patients rarely touched nurses more than was necessary. In some cases, nurses had to cope with violent touching by patients. Some women nurses interpreted touches by male patients as having a sexual nature and as annoying. This had taught male patients to avoid touching nurses. On the other hand, friendly and grateful touches by patients were very important to nurses. When used for emotional purposes only, touching presupposed a good relationship between nurses and their patients. Although touching is extremely common in nursing practice, there has been very little research into its meaning. More work is therefore needed to explore the role and meaning of touching in nursing.

Effects of sex and sex roles on avoidance of same- and opposite-sex touch

Touch and touch avoidance are important facets of interpersonal relations. Touch avoidance has been related to sex, but the relationship between touch and sex roles has not been widely substantiated. 259 undergraduate students participated in a procedure designed to test the relationship between sex, sex roles, and same-sex and opposite-sex touch avoidance. Significant differences were reported between men and women on same-sex touch avoidance but not on opposite-sex touch avoidance. Participants high on androgyny reported less same-sex and opposite-sex touch avoidance than did subjects low on androgyny. No interactive effect between sex and androgyny was found for either same-sex or opposite-sex touch avoidance. Regression procedures indicated predictive models for sex and androgyny in relation to same-sex and opposite-sex touch avoidance. Specific conclusions regarding the relationships among sex, androgyny, and touch avoidance were stated.

Gender and national differences in attitudes toward same-gender touch

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.

Effects of sex and sex roles on same-sex touch

Touch is an important aspect of nonverbal behavior. Important aspects of the relationship of gender and sex roles with same-sex touch were highlighted. 259 subjects participated in the procedure, yielding a significant difference between men and women on same-sex touch. Further, androgyny was significantly correlated with ratings on the Same-sex Touching Scale. Specific conclusions regarding these findings were discussed.
