Sensory differences and anxiety disorders are highly prevalent in autistic individuals with and without ADHD. Studies have shown that sensory differences and anxiety are associated and that intolerance of uncertainty (IU) plays an important role in this relationship. However, it is unclear as to how different levels of the sensory processing pathway (i.e., perceptual, affective, or behavioral) contribute. Here, we used psychophysics to assess how alterations in tactile perception contribute to questionnaire measures of sensory reactivity, IU, and anxiety. Thirty-eight autistic children (aged 8-12 years; 27 with co-occurring ADHD) were included. Consistent with previous findings, mediation analyses showed that child-reported IU fully mediated an association between parent-reported sensory reactivity and parent-reported anxiety and that anxiety partially mediated an association between sensory reactivity and IU. Of the vibrotactile thresholds, only simultaneous frequency discrimination (SFD) thresholds correlated with sensory reactivity. Interestingly, we found that sensory reactivity fully mediated an association between SFD threshold and anxiety, and between SFD threshold and IU. Taken together, those findings suggest a mechanistic pathway whereby tactile perceptual alterations contribute to sensory reactivity at the affective level, leading in turn to increased IU and anxiety. This stepwise association can inform potential interventions for IU and anxiety in autism.

This study evaluated the impact of three distinct diets; perennial ryegrass (GRS), perennial ryegrass/white clover (CLV) and total mixed ration (TMR), on the sensory properties and volatile profile of whole milk powder (WMP). The samples were evaluated using a hedonic sensory acceptance test (n = 99 consumers) and by optimised descriptive profiling (ODP) using trained assessors (n = 33). Volatile profiling was achieved by gas chromatography mass spectrometry using three different extraction techniques; headspace solid phase micro-extraction, thermal desorption and high capacity sorptive extraction. Significant differences were evident in both sensory perception and the volatile profiles of the WMP based on the diet, with WMP from GRS and CLV more similar than WMP from TMR. Consumers scored WMP from CLV diets highest for overall acceptability, flavour and quality, and WMP from TMR diets highest for cooked flavour and aftertaste. ODP analysis found that WMP from TMR diets had greater caramelised flavour, sweet aroma and sweet taste, and that WMP from GRS diets had greater cooked aroma and cooked flavour, with WMP derived from CLV diets having greater scores for liking of colour and creamy aroma. Sixty four VOCs were identified, twenty six were found to vary significantly based on diet and seventeen of these were derived from fatty acids; lactones, alcohols, aldehydes, ketones and esters. The abundance of δ-decalactone and δ-dodecalactone was very high in WMP derived from CLV and GRS diets as was γ-dodecalactone derived from a TMR diet. These lactones appeared to influence sweet, creamy, and caramelised attributes in the resultant WMP samples. The differences in these VOC derived from lipids due to diet are probably further exacerbated by the thermal treatments used in WMP manufacture.

This article explores avian experiences with toxic war processes that unfold across space and time. Joining together three evolving areas of interest in global politics – ontologies of war, interspecies relations, and sensory politics – the article develops a view of war that centres ongoing war processes that affect more-than-human life in and outside of international warzones. Advancing a multispecies form of inquiry attentive to local voices, including Upper Cook Inlet Tribes, the article examines how interspecies relations emerge in national security debates about long-lasting ecological costs of war. Specifically, it offers an analysis of US Department of Defense hearings surrounding the controversy over reopening Eagle River Flats – an Alaskan estuary that had been polluted with white phosphorus munitions – for weapons testing and training during the Iraq War. The article also considers the experiences of two migratory avian communities (northern pintails and tundra swans) with toxic white phosphorus pollution, illustrating more-than-human sensory perspectives on the space and time of war processes. These conceptual and empirical moves reposition national security concerns about wartime risk into a much broader post-anthropocentric perspective.

Creating individualised activities in partnership with people who have moderate dementia and their partners at home has rarely been achieved, as such interventions are usually pre-planned by researchers or professionals. The academic gap is in the activity design being led by the person who has dementia and their partner and how to engage them in a meaningful manner which rekindles positive joint memories and improves the quality of their current relationship. This article explores the meaning and significance of recalling shared holiday memories for people living with moderate dementia and their partners, using multisensory reminiscence. A sensory ethnography research methodology was employed which enhanced co-design of the activity over five home visits. The research culminated in the creation of a digital story, sharing of food and drink, and re-enactment through exploration of their holiday memorabilia: forming their suitcase of memories (SOM). The study extends the current academic debate of co-produced interventions and identifies the critical themes of ‘holidays as life’, ‘freedom’, ‘view seen, viewpoint heard’ and ‘strengthened self-identity with younger self’ which emerged from the research. Such areas of sensory reminiscence have supported positive recollections, discourse and, when combined, resulted in a beneficial impact on the partner's shared relationship. A significant research outcome was the transition from a negative life view dominated by dementia to rekindling their relationship positively as a result of the SOM intervention and sensory methodology. Future research to continue the work with new couples to see if similar results are achieved with more case studies is needed.

This paper aims to develop a sensory methodological framework to explore older user's landscape experience. Applying empirical experience in Australian aged-care facilities, it addresses a methodological gap in the current literature to help move beyond the current taken-for-granted approaches such as interviews, cognitive mapping, behavioural observation and visual methods. We propose a more holistic method which enables the exploration of older people's in situ environmental experience. The multisensory framework we propose here is based on the first author's doctoral fieldwork experience that took place in two aged-care facilities in Brisbane, Australia. Findings suggest this framework facilitates an understanding of users’ olfactory, auditory and visual responses to the physical environment, and promotes a deeper engagement with the landscape. We argue that this is essential to promoting good landscape design which genuinely connects with older people's needs.

The Wisconsin Twin Project comprises multiple longitudinal studies that span infancy to early adulthood. We summarize recent papers that show how twin designs with deep phenotyping, including biological measures, can inform questions about phenotypic structure, etiology, comorbidity, heterogeneity, and gene–environment interplay of temperamental constructs and mental and physical health conditions of children and adolescents. The general framework for investigations begins with rich characterization of early temperament and follows with study of experiences and exposures across childhood and adolescence. Many studies incorporate neuroimaging and hormone assays.

In grass-based beef production systems (PS), early maturing (EM) breed types may be preferable to late maturing (LM) breed types in achieving adequate carcass fat cover. Biochemical and organoleptic characteristics of muscle from suckler bulls were investigated in EM and LM (n=28/breed) assigned to one of two PS (ad libitum concentrates and grass silage to slaughter (C) or ad libitum silage plus 2 kg concentrate daily during winter followed by 99 days at pasture and then an indoor finishing period on C (GSPC)) in a 2 breed type×2 PS factorial arrangement of treatments. Bulls were managed to have a common target carcass weight of 380 kg. Intramuscular fat (IMF) content was higher (P<0.05) for EM than LM, and for C than GSPC bulls. Collagen solubility was higher (P<0.05) for C than GSPC bulls. Lactate dehydrogenase (LDH) and phosphofructokinase activities were higher (P<0.05) for LM than EM. Isocitrate dehydrogenase activity and the Type I myosin heavy chain (MyHC) proportion were higher (P<0.05) for EM than LM. The LDH activity and the Type IIX MyHC proportion were higher (P<0.05) for C than GSPC bulls. Sensory ratings for tenderness and juiciness were higher (P<0.01) for beef from EM than LM while sensory ratings for tenderness, flavour liking and overall liking were higher (P<0.001) for C than for GSPC bulls. Differences in sensory quality were largely eliminated when adjusted for IMF. Overall, carcass fat scores, IMF and sensory scores were higher in EM than LM and in C than GSPC bulls but most differences in sensory quality could be attributed to differences in IMF.

The Wisconsin Twin Research Program comprises multiple longitudinal studies that utilize a panel recruited from statewide birth records for the years 1989 through 2004. Our research foci are the etiology and developmental course of early emotions, temperament, childhood anxiety and impulsivity, autism, sensory over-responsivity, and related topics. A signature feature of this research program is the breadth and depth of assessment during key periods of development. The assessments include extensive home- and laboratory-based behavioral batteries, recorded sibling and caregiver interactions, structured psychiatric interviews with caregivers and adolescents, observer ratings of child behavior, child self-report, cognitive testing, neuroendocrine measures, medical records, dermatoglyphics, genotyping, and neuroimaging. Across the various studies, testing occasions occurred between 3 months and 18 years of age. Data collection for some aspects of the research program has concluded and, for other aspects, longitudinal follow-ups are in progress.

Knowing what information, and from which sensory cues, is available to an animal regarding its position and direction of movement is vital for unravelling the mechanisms underlying animal navigation. Although considerable progress has been made with traditional field and laboratory techniques, these approaches generally do not provide direct control over the animal's motivation to display its sensory abilities. In contrast, psychologists have for many decades used conditioning as a reliable tool to study sensory perception as well as the mechanisms underlying learning. There has been growing interest in the use of conditioning techniques to investigate responses to stimuli that might be used in guiding movement over long distances. This review seeks to facilitate that development by providing a general introduction to conditioning and the considerations involved in designing robust conditioning experiments together with a perspective for its future use in studying sensory systems in migratory and homing species.

An algorithm is presented for the on-line generation of minimum-time trajectories for robot manipulators. The algorithm is designed for intelligent robots with advanced on-board sensory equipment which can provide the position and orientation of the end-effector. Planning is performed in the configuration (joint) space by the use of optimised combined polynomial splines, along with a search technique to identify the best minimum-time trajectory. The method proposed considers all physical and dynamical limitations inherent in the manipulator design, in addition to any geometric path constraints. Meeting the demands of the heavy computations involved lead to a distributed formulation on a multiprocessor system, for which an intelligent control unit has been created to supervise its proper and practical implementation. Simulation results of a proposed case study are presented for a PUMA 560 robot manipulator.

This work studied the addition of an adequate lipase to enhance lipolysis reactions and the development of piquant flavour and sharp odour in Idiazabal cheese, as an alternative to the use of lamb rennet paste. Cheeses were manufactured from bulk raw ewes' milk in 50 l vats with commercial bovine rennet and 80 lipase units of pregastric or 180 lipase units of fungal lipase and ripened for 180 days. A higher lipolytic activity was induced by lipase addition promoting strong changes in odour and flavour attributes. Both fungal and pregastric lipases increased the content of total free fatty acids (FFA), but the fungal lipase released mainly medium- and long-chain FFA. In contrast, the pregastric lipase preferably released short-chain FFA. Diglyceride (DG) content was considerably higher in cheeses made with added pregastric lipase compared with those made with fungal lipase or with no lipase. Monoglycerides (MG) were detected only in cheeses made with either lipase added, reaching comparable concentrations after ripening for 180 days. The cheeses made with pregastric lipase had the highest scores for odour and flavour intensity, and sharp and rennet odours, desirable attributes for the Idiazabal cheese made with lamb rennet paste. None of the texture attributes were significantly influenced by the concentrations of MG and DG in the cheeses made with either lipase. Thus, the pregastric lipase was more appropriate than the fungal lipase to develop a more traditionally-flavoured Idiazabal cheese.

Hospitalized older adults with dementia often have few opportunities for social interaction and psychological stimulation. Their psychological functioning is affected by the dementing illness, sensory impairment and the effects of living in an institutional environment. The adverse effects of sensory deprivation may be particularly relevant for this client group. Using a multiple single case design, we evaluated the effects of individual sensory stimulation sessions on four elderly patients with dementia. All were living on a hospital continuing care psychiatric ward. Detailed behavioural observations were made before, during and after sessions to assess patients’ responses. Adaptive functioning and wellbeing were also investigated. Results indicated that the intervention led to observable changes in levels of interaction, active looking and interest. The effects were transitory with the exception of active looking, which endured following the session. Adaptive behaviours also improved, though there was no change in wellbeing. The study indicates that sensory stimulation is a valuable therapeutic intervention with this client group.

Nasal airflow modifies the pattern of ventilation presumably due in part to nervous signals arising in the nose and transmitted along the trigeminal nerve to the respiratory centre. Nasal receptor tissue must also be important in determining the sensation of airflow at a conscious level but little attention has been paid to the distribution and function of these receptors.

An experimental model to deliver a pulse of air at different velocities to various nasal test sites is described. In this way nasal sensitivity to an air jet can be mapped out. Sensitivity of the nose to an air jet is greatest at the entrance to the nose – the region of the nasal vestibule.
