Good vibrations: Global processing can increase the pleasantness of touch

Visual–tactile carry-over effects of global/local processing (attention to the whole, versus the details) have been reported under active touch conditions. We investigated whether carry-over effects of global/local processing also occur for passive touch and whether global/local processing has differential effects on affective and discriminative aspects of touch. Participants completed two tactile tasks involving pleasantness rating and discrimination of a set of tactile vibrations before and after completing a version of the Navon task that encouraged a focus on the global (n?=?30), local (n?=?30), or both (n?=?30) features of a series of visual stimuli. In line with previous research suggesting a link between global processing and positive emotion, global processing increased pleasantness ratings of high-frequency (but not low-frequency) tactile vibrations. Local processing did not improve the ability to discriminate between vibrations of different frequencies, however. There was some evidence of a tactile–visual carry-over effect; prior local processing of tactile vibrations reduced global precedence during the Navon task in the control group. We have shown carry-over effects of global versus local processing on passive touch perception. These findings provide further evidence suggesting that a common perceptual mechanism determines processing level across modalities and show for the first time that prior global processing affects the pleasantness of touch.     

Early tactile experience of low birth weight children: links to later mental health and social adaptation

The purpose of this study was twofold: to determine (1) the degree to which specific qualities of maternal touch may contribute to the low birth weight infant's emotional and behavioural problems as well as social adaptation, and (2) the relationship between maternal touch and a mother's other caregiving behaviour. The sample included 114 socioculturally diverse infants and their mothers who were videotaped during an infant feeding when the baby was 3 months old. This videotape was analysed to assess dimensions of mother–infant interaction, including maternal touch. Data on perinatal risk and the mother's acceptance versus rejection of the infant were also acquired. Social adaptation and emotional/behavioural problems were measured when the child was 2 years of age. Hierarchical regression analyses indicated that maternal touch accounted for 15% of the variance in the likelihood of a child having emotional/behavioural problems at age 2. Children who received more nurturing touch had significantly fewer internalizing problems (such as depression) while children receiving both more frequent touch and harsh touch had more externalizing problems (such as aggressive behaviour). Infants who were less responsive to their caregivers were especially at risk of developing aggressive/destructive behaviour as a result of frequent touch. But less responsive infants also appeared to benefit most from greater use of diverse types of maternal touch, accounting for 6% of the variance in superior adaptive behaviour at age 2. Nurturing touch was the only quality that showed even a modest relationship to other caregiving behaviour, suggesting that touch may play a distinct role in the infant's psychosocial development.

A longitudinal investigation of maternal touching across the first 6 months of life: Age and context effects

The types of touch used by 12 mothers with their 1-, 3- and 5.5-month-old infants were examined longitudinally during two different interaction contexts lasting 5 min each. Changes in maternal touching as a function of infants’ age and interaction context were revealed.     

恋爱关系中触摸和依恋对嫉妒的影响

选取恋爱中的青年,探讨触摸类型、依恋和嫉妒的关系。实验1选取50名大学生,采用想象情境范式,探究触摸类型（分为“无触摸、脸部触摸和腰部触摸”三种条件）对嫉妒的影响。选择害怕、生气、尴尬、性唤起、悲伤和妒忌作为测量指标。结果显示,三种条件下嫉妒情绪无显著差异。实验2选取113名青年,将无触摸条件分为远距离和近距离两种,进一步探讨触摸类型、依恋和嫉妒的关系。依恋的测量选用亲密关系经验问卷,分为焦虑、回避两个维度。结果发现：（1）在远距离无触摸条件下,依恋焦虑和悲伤、害怕、妒忌、生气正相关;（2）近距离无触摸条件下,依恋回避和悲伤、妒忌、生气负相关;（3）脸部触摸条件下,依恋焦虑和害怕、性唤起正相关。总的来看,爱情依恋对嫉妒情绪的影响受到触摸类型的调节。     

Conscious mind – conscious body

The incorporation of body awareness and touch techniques within analytic treatment is the main theme of this paper. Beginning with a personal experience of the oneness of body and psyche, the author considers Jung's observation of the physiological accompaniments of emotional reactions and his understanding of body as both shadow and ground. The author proposes a new model of analytic treatment that embraces both the verbal and imaginal as well as the non-verbal and somatic aspects of psyche. She describes the three elements of her approach: 1) reading what the body is saying about psyche; 2) using the body as an organ of perception; 3) using touch as a therapeutic tool. The effects of the taboo around touch are considered. Clinical examples throughout the paper demonstrate how somatic awareness and the use of touch promote the analytic process.     

A place for nouns and a place for verbs? A critical review of neurocognitive data on grammatical-class effects

It is generally held that noun processing is specifically sub-served by temporal areas, while the neural underpinnings of verb processing are located in the frontal lobe. However, this view is now challenged by a significant body of evidence accumulated over the years. Moreover, the results obtained so far on the neural implementation of noun and verb processing appear to be quite inconsistent. The present review briefly describes and critically re-considers the anatomo-correlative, neuroimaging, MEG, TMS and cortical stimulation studies on nouns and verbs with the aim of assessing the consistency of their results, particularly within techniques. The paper also addresses the question as to whether the inconsistency of the data could be due to the variety of the tasks used. However, it emerged that neither the different investigation techniques used nor the different cognitive tasks employed fully explain the variability of the data. In the final section we thus suggest that the main reason for the emergence of inconsistent data in this field is that the cerebral circuits underlying noun and verb processing are not spatially segregated, at least for the spatial resolution currently used in most neuroimaging studies.     

"That's not a real body": identifying stimulus qualities that modulate synaesthetic experiences of touch

Mirror-touch synaesthesia is a condition where observing touch to another’s body induces a subjective tactile sensation on the synaesthetes body. The present study explores which characteristics of the inducing stimulus modulate the synaesthetic touch experience. Fourteen mirror-touch synaesthetes watched videos depicting a touch event while indicating (i) whether the video induced a tactile sensation, (ii) on which side of their body they felt this sensation and (iii) the intensity of the experienced sensation. Results indicate that the synaesthetes experience stronger tactile sensations when observing touch to real bodies, whereas observing touch to dummy bodies, pictures of bodies and disconnected dummy body parts elicited weaker sensations. These results suggest that mirror-touch synaesthesia is not entirely bottom-up driven, but top-down information, such as knowledge about real and dummy body parts, also modulate the intensity of the experience.

The Use of Touch in Counseling: An Ethical Decision‐Making Model

Although some counselors have advocated for the limited use of touch in counseling, others have argued that touch has no place within the counseling relationship. Despite the controversy, the use of touch has been shown to have a number of therapeutic benefits; however, there are few ethical decision‐making models that are appropriate for considering the use of touch in counseling. The authors discuss the controversy surrounding the use of touch and the benefits/contraindications of touch. The 5 ethical principles of counseling are also examined; a new ordering of the principles is presented as a useful ethical decision‐making model when considering the use of touch in counseling.     

Stimulus generalization of behavioral history

Undergraduates responded under a variable-ratio 30 schedule in the presence of a 25-mm long line and on a differential-reinforcement-of-low-rate 6-s schedule when a 13-mm long line was present. Following this, a line-length continuum generalization test was administered under a fixed-interval 6-s schedule (Experiment 1) or extinction (Experiment 2). In both experiments, obtained generalization gradients conformed to typical postdiscrimination gradients. Responses were frequent under stimuli physically similar to the 25-mm line and infrequent under stimuli physically similar to the 13-mm line. The generalization gradients were generally asymmetric with peak response rates occurring at line lengths greater than 25 mm.
