RESUMO

Agricultural extension services have been successful in promoting knowledge sharing and innovation in agriculture. However, the adoption of new agricultural practices, particularly in integrated pest management, has been slow. Using a case study with a co-designed survey instrument, this research aimed to understand how growers in the Southwest Western Australian Grainbelt access information and resources to manage fungicide resistance. We found that the growers rely on a combination of paid agronomists, government or research institutes, local grower groups, and field days for fungicide resistance information. Growers seek information from trusted experts who can simplify complex research, value easy-to-understand communication and prefer resources tailored to their local context. Additionally, growers valued information regarding new fungicide developments and having access to rapid fungicide resistance diagnostic services. These findings highlight the importance of providing growers with effective agricultural extension services to manage the risk of fungicide resistance.

RESUMO

OBJECTIVES: Virtual reality (VR) is increasingly used for training the dementia care workforce. It is unknown whether VR is superior to traditional training techniques in improving dementia care amongst practicing nurses. This study compared the impact of a VR application on nurses' knowledge and attitudes towards people living with dementia, to video-based, non-immersive training. METHODS: Twenty-two registered and enrolled nurses were randomised to either interactive VR experience or video footage captured from within the app. Participants completed surveys pre- and post-training to assess their knowledge of dementia, attitudes towards dementia and person-centredness. Engagement with training was assessed objectively using facial electromyography, and subjectively with self-reported scales. RESULTS: Virtual reality evoked objectively significant greater positive and negative emotional responses than video (positive emotion fEMG: VR mean .012 mV vs. video .005 mV, F[1, 20] = 8.70, p = .01; negative emotion fEMG: VR mean .018 mV vs. video .008 mV, F[1, 20] = 18.40, p < .001). Self-ratings of engagement and emotional state were similar. There was little change in the VR group's knowledge of, and attitudes towards, dementia; the video group's dementia knowledge improved (total DKAS mean differences: VR .1 t = .07, df = 9, p = .95 vs. video -2.3 t = -2.265, df = 11, p = .045). CONCLUSIONS: Virtual reality is more engaging than traditional training in highly experienced dementia care practitioners. Despite this, VR may not be superior to traditional training techniques to improve knowledge and attitude for many learners. A focus of future research in the area should be on how to capitalise on VR's greater emotional engagement so that Australia's nursing workforce is better equipped to care for the increasing number of people living with dementia.

RESUMO

AIMS AND OBJECTIVES: The study's aim was two-fold: (1) to explore the experiences and perceptions of industry, academic, and research professionals concerning technologies used within aged care; and (2) to identify needs-led priorities for the future development and application of technologies within aged care. BACKGROUND: Global population ageing requires a recalibration of aged care policies, systems, and services to promote and support healthy ageing. It is expected that technology will play an important role in this regard. This study qualitatively assessed the landscape of technology use in aged care from the perspective of industry, academic, and research professionals. DESIGN: A purposefully designed cross-sectional survey collecting experiences, perspectives, and barriers about technology through open responses. METHODS: Using convenience sampling, thirty-five participants completed an online survey between April and October 2020. A descriptive qualitative content analysis approach was used to analyse the written responses. Reporting of findings followed the EQUATOR's Standards for Reporting Qualitative Research checklist. RESULTS: Four themes were identified that characterised the use of technologies within aged care: (1) User Perceptions and Attitudes: wariness and reluctance to technology; (2) Systemic Issues within Aged Care: Under-resourced with opportunities for innovation; (3) Technology-Related Barriers: Equity, costs, privacy, integration, and interoperability and (4) Research Priorities: Co-design and integration of technology. CONCLUSIONS: The existing technology does not meet the needs of older people, aged care personnel and the system in general, which prevents its successful implementation and uptake.

RESUMO

Previous research has shown that the proactive deprioritization of emotional distractors through the provision of information about the distractors or passive habituation of emotional distractors may attenuate emotion-induced blindness (EIB) in the rapid serial visual presentation stream. However, whether prior memory encoding of emotional distractors could bias the EIB effect remains unknown. To address this question, this study employed a three-phase paradigm integrating an item-method direct forgetting (DF) procedure with a classic EIB procedure. Participants completed a memory coding phase to either remember or forget negative pictures, then performed an intermediate phase of the EIB test, and finally finished a recognition test. Critically, the same to-be-forgotten (TBF) and to-be-remembered (TBR) negative pictures in the memory learning phase were used as emotional distractors in the intermediate EIB test. The results replicated the typical DF effect by showing higher recognition accuracies for TBR pictures compared to those for TBF pictures. More importantly, the TBF negative distractors attenuated the EIB effect compared to the TBR negative distractors, but showed a comparable EIB effect as the novel negative distractors. These findings indicate that prior memory encoding manipulations of negative distractors could bias subsequent EIB effects, providing an important approach to modulate the EIB effect.

RESUMO

Using event-related potentials (ERPs), the present study tested whether state empathy for pain of experienced physicians could resist the influences of repeated exposure to depictions of people experiencing pain. We employed a three-phase paradigm which integrated a classical pain empathy measurement procedure and a multi-block free-view habituation procedure. In this paradigm, 18 experienced physicians with reduced empathy traits (clinical experience > 5 years) and 18 non-physician controls completed a pre-test phase of pain empathy, followed by a phase of repeated emotional exposure, and a post-test phase of pain empathy. Behavioral pain intensity rating and critical ERP components associated with pain empathy (i.e., N1, N2, and LPP) were measured and compared across participant groups, stimulus types, and experimental phases. Experienced physicians differed from controls in neural processes related to pain empathy, but their pain intensity ratings did not. Specifically, for early ERP components related to empathic arousal such as N1 and N2, we replicated and extended previous findings that physicians can inhibit these bottom-up processes of empathic arousal. In contrast, the P3 didn't reflect a distinctive empathy process for the physicians. For the later reappraisal-related LPP component, however, we found a significant three-way interaction among participant groups, stimulus types, and experimental phases. This interaction provided the first evidence that pain empathy of experienced physicians with low empathic traits can resist repeated exposure to pain. Based on this evidence, the characteristics of pain empathy for experienced physicians and the relative adaptability of pain empathy for human beings are discussed.

RESUMO

Recent research has shown that emotion-induced blindness (EIB) can be attenuated by strengthening the attentional prioritization of perceptual targets in the rapid serial visual presentation stream and/or proactively inhibiting emotional distractors. However, whether EIB can be attenuated by reducing the attentional prioritization of emotional distractors through passive habituation remains unknown. To address this question, the present experiment utilized a novel three-session paradigm including a pre- and post-EIB measurement session and an intermediate multiblock free-view habituation session. In order to examine the effectivity and specificity of the habituation effect on EIB, four groups of participants underwent the same pre- and post-EIB measurement session but completed the habituation session with different kinds of pictures: (a) repeated negative pictures, which were seen in pre-EIB; (b) repeated neutral pictures, which were seen in pre-EIB; (c) novel negative pictures, which were never seen in pre-EIB; and (d) novel neutral pictures, which were never seen in pre-EIB. The results showed that the EIB effect was only significantly attenuated after habituation to repeated negative pictures. This finding indicates that emotional interference in EIB can be attenuated by reducing the attentional prioritization of emotional distractors through habituation. Furthermore, similar EIB attenuation after habituation to repeated neutral pictures suggests that the habituation-induced attenuation might be context specific. These results provide a potentially new and important approach to reduce EIB effects. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMO

Fresh truffles which include black truffle (Tuber melanosporum Vittadini) deteriorate and lose aroma rapidly after harvest; therefore, postharvest processing via freeze-drying or encapsulation is an option to preserve truffle aroma for extended supply. However, the aroma profile that directly affects the truffle quality and consumer acceptance is influenced by processing and producers require processing options that balance processing feasibility with retention of a suitable aroma profile. This study aimed to determine the impact of freeze-drying and encapsulation on the profile of key volatiles, consumer discrimination, and overall sensory impression (aroma intensity, liking, and acceptability) of processed truffle products compared to the starting material (positive control). The study combined experimental-scale processing with GC-MS analysis and consumer sensory evaluation to compare and optimize postharvest processing options. Based on the results, some volatile changes were detected in the processed truffle products compared to the positive control which were aligned with the consumer discrimination (triangle test) and the aroma intensity score (consumer sensory test). Despite some chemical and sensory differences detected, the consumer panel did not have any preference for processed truffle products compared to the positive control. The overall finding indicates the potential value of processing truffles into a natural flavoring ingredient for food application via freeze-drying or encapsulation, which should be of great interest for the truffle and food industry. According to the correlation analysis, the consumer acceptance of a truffle product may be increased by retaining 1-octen-3-ol and methional, while reducing the amount of p-cresol in the product. PRACTICAL APPLICATION: The postharvest process of turning truffles into a food flavoring ingredient may cause undesirable volatile changes that would directly impact the aroma quality and consumer acceptance of the processed truffle products. Hence, the impacts of freeze-drying and encapsulation on the chemical and sensory profile of truffles were evaluated in this study. Overall, the results of the concurrent instrument and sensory analysis demonstrated that both freeze-drying and encapsulation are potential options for processing.

RESUMO

Constant competition and changing consumer preferences prompts the need to improve the competitiveness of the Australian pork industry. This study examines the heterogeneity of Australian consumer preferences related to fresh pork cues. Using best-worst scaling, we examine the importance of 15 intrinsic and 31 extrinsic product attributes to 196 Australian consumers. Findings reveal that taste, succulence and the smell of boar taint were the most important intrinsic cues, while animal welfare and naturalness were the most important extrinsic cues. Based on the importance of intrinsic cues, four segments were identified, namely boar taint haters, lean meat eaters, colour lovers and cuts and size matters. Four segments based on extrinsic cues were identified as animal and environment lovers, naturalness lovers, demanding buyers and utilitarian buyers. This study contributes significantly to the industry by offering granular insights with respect to Australian consumer demands and optimal communication of cues.

RESUMO

We undertook a qualitative assessment of aged care technology needs from the perspective of consumers and providers using a cross-sectional survey that assumed a largely open-response format. We recruited a convenience sample of individuals aged 18 years or older, lived in Australia, and self-identified as either an older adult (n = 133), an informal caregiver of an older adult (n = 27), and/or clinician, healthcare practitioner, and aged care provider (n = 148). Survey responses were analyzed using a descriptive qualitative content analysis approach to interpret meaning from written survey responses. We identified seven themes reporting that technologies used in aged care do not appear to be meeting end-user needs. Supporting the Technology Acceptance Model, consumers and providers perceive usefulness of the technology and its actual ease of use as drivers of acceptance toward gerontechnology. Ten recommendations are proposed to support technology use and the quality of aged care.

RESUMO

Previous studies have revealed that stereotyping processes involving negative affective content (e.g., antipathy) can lead to a significant increase in insula activity. However, whether the insula is sensitive to stereotype inconsistency or plays a crucial role in stereotype regulation remains unclear. To help fill this gap, 21 young adults were presented with a modified single-category implicit association test (SC-IAT) that assessed their stereotypes about rural migrant workers. In a within-subjects design, participants completed separate blocks of compatible and incompatible trials, each of which consisted of stereotype-consistent or stereotype-inconsistent trait labels that had a positive or a negative valence. Functional MRI was used to identify specific brain regions associated with negative and positive stereotyping. The behavioral results revealed a typical stereotype regulation effect in which participants responded slower to stereotype-inconsistent condition than stereotype-consistent condition, although such effect was significantly modulated by IAT compatibility, rather than by emotional valence. MRI results revealed that activity in the right insula was significantly sensitive to stereotype regulation processes in negative incompatible tasks, whereas such effect was marginally significant in positive incompatible tasks. Moreover, psychophysiological interaction analyses indicated complex functional connectivity among the right insula and cognitive control regions [e.g., ventrolateral prefrontal cortex (vlPFC) and dorsal anterior cingulate cortex (dACC)], social mentalizing regions [medial prefrontal cortex (mPFC)], and motivation regions (putamen) in the condition where negative stereotypes were violated. Taken together, these findings demonstrate that the right insula serves as a crucial node in regulating implicit stereotyping, particularly in negative stereotyping tasks.

RESUMO

This study investigates the relationship between the COVID-19 threat and consumer evaluation of a product with authenticity appeals in advertisements. We propose that threatening situations like COVID-19 motivate consumers to lower their uncertainty and increase their preference for products with authentic advertising messages. Because individuals react differently to threatening environments according to their early-life experiences, commonly reflected in childhood socioeconomic status, we examined whether childhood socioeconomic status moderates the relationship between threat and consumer evaluation of authenticity in advertisements. First, secondary data from Google Trends provided empirical support for our predictions. In additional experimental studies, participants evaluated different target products in four studies that either manipulated (Studies 2 and 3) or measured (Studies 4 and 5) COVID-19 threat. Our results provide converging evidence that consumers positively evaluate products with authentic advertising messages under the COVID-19 threat. Consumers' motivation to lower their uncertainty underlies the effect of COVID-19 threat on their evaluation of authentic messages (Study 3). This attempt to reduce uncertainty is more likely to occur for consumers with relatively higher childhood socioeconomic status (Studies 4 and 5). These findings suggest that using authenticity appeals during a pandemic could effectively reduce consumers' perceived uncertainty and generate positive consumer evaluations.

RESUMO

Previous research has indicated that frontal midline theta (FMθ) reflects a domain-general cognitive control mechanism of the prefrontal cortex. Brain imaging studies have shown that the inhibition of implicit stereotypes was dependent on this domain-general cognitive control mechanism. Based on this knowledge, the present study investigated the neural oscillatory correlates of implicit gender stereotype control in an extrinsic affective Simon task (EAST) using electrophysiological methods. Participants in this task conducted verification to white gender names and colored gender traits, and their behavioral response and electroencephalogram (EEG) were recorded during their performances. As predicted, stereotype-inconsistent trials resulted in reduced response accuracies and slower response times than stereotype-consistent trials. For the event-related potential (ERP) results, the enhanced performance of stereotype-inconsistent trials was accompanied by an enhanced N400 amplitude but an attenuated late positive potential amplitude. In contrast, early attentional components such as P2 and N2 as well as their amplitudes were impacted by the experimental manipulations and individual differences in gender factors. In addition, based on time-frequency (TF) analysis, we found that the enhanced performance of stereotype-inconsistent trials was also accompanied by an event-related synchronization on the frontal theta oscillation. This frontal theta appeared at a late processing stage and persisted across a time window from N400 to late positive potential. Additionally, this enhanced frontal theta effect was not modulated by the experimental manipulations and individual differences in gender factors. Based on these findings, the feature of frontal theta oscillation in the implicit gender stereotype control process was discussed.

RESUMO

Public health sponsorship is a unique phenomenon in Australia. The current research examines the critical success factors of Western Australian Health Promotion Foundation's (Healthway) sponsorship program, Australia's largest public health sponsorship program. Using stakeholder interviews and expert observational studies, two studies present five key success factors: (i) effective segmentation and targeting of health messages; (ii) collaboration between Healthway and partnering organization to leverage sponsored events; (iii) displacement of unhealth sponsorship; (iv) use of leveraging strategies to raise awareness of health messages; and (v) environmental changes that facilitate behavioural change. The current research provides insights into how and why sponsorship is an effective public health promotion tool.

RESUMO

OBJECTIVE: The aim of the study was to explore the feasibility of using telepresence robots to encourage interactive communication in dementia care, from the perspective of family carers. METHODS: Qualitative findings from semi-structured interviews with six family carers. RESULTS: Generally, family carers reported a feeling of presence and connectedness when talking to their family member via the telepresence robots. They reported the robots as helping to enhance longer conversations and social connection with their family member. CONCLUSION: Telepresence may offer potential to encourage social connection, in particular where families are unable to make regular visits to the nursing home.

RESUMO

A vivid sense of motion can be inferred from static pictures of objects in motion. Like perception of real motion (RM), viewing photographs with implied motion (IM) can also activate the motion-sensitive visual cortex, including the middle temporal complex (hMT+) of the human extrastriate cortex. Moreover, extrastriate cortical activity also increases with motion coherence. Based on these previous findings, this study examined whether similar coherence level-dependent activity in motion-sensitive human extrastriate cortex is seen with IM stimuli of varying coherence. Photographic stimuli showing a human moving in four directions (left, right, toward, or away from the viewer) were presented to 15 participants. The coherence of the stimuli was manipulated by changing the percentage of pictures implying movement in one direction. Electroencephalographic data were collected while participants viewed IM or counterpart non-IM stimuli. The P2 response of extrastriate visual cortex (source located at hMT+) increased bilaterally with coherence level in the IM conditions but not in the non-IM conditions. This finding demonstrates that extrastriate visual cortical responses are progressively activated as motion coherence increases, even when motion is inferred, providing new support for the view that the activity of human motion-sensitive extrastriate visual cortex can be modulated by top-down perceptual influences in addition to its well-established role in processing bottom-up sensory signals.

RESUMO

Objectives: To explore the acceptability of telepresence robots in dementia care from the perspectives of people with dementia, family carers, and health professionals/trainees, and investigate the utility of a social presence assessment tool, the Modified-Temple Presence Inventory (Modified-TPI), for people with dementia. Method: A mixed-methods pilot study conducted in a social robotics laboratory. Three participant groups (n = 22) - dyads of people with dementia and their carers (n = 5 respectively), and health professionals/trainees (n = 12) - participated in individual one-off intervention sessions with the telepresence robot, Giraff, with follow-up interviews. Sessions covered how to use Giraff, followed by interactive practice in making a video-call involving conversation and manoeuvring of Giraff. Participants with dementia experienced receiving a call made by their carer; healthcare professionals/trainees experienced making and receiving a call. Outcomes of interest were sense of presence [Modified-TPI], affective response (International Positive and Negative Affect Schedule [I-PANAS-S]; Observable Displays of Affect Scale [ODAS]), and attitudes and reactions to Giraff (semi-structured interviews). Results: Participants reported a sense of authenticity and social connection through the experience. They indicated positive social presence through Giraff, and significantly higher positive (mean score 18.77; ±4.00) than negative affect (mean score 8.05; ±1.76) on the I-PANAS-SF, and on the facial display subscale of the ODAS (positive - mean score 15.50; ±3.51 versus negative - mean score 4.00; ±0.00). Conclusion: Telepresence has potential use in situations where people with dementia require social connection. Studies with larger sample sizes, varied characteristics, and cost-effectiveness analysis are needed to inform the application of telepresence in healthcare practice.

RESUMO

AIM: To develop and psychometrically test the Engagement of a Person with Dementia Scale. BACKGROUND: It is important to study engagement in people with dementia when exploring the effectiveness of psychosocial interventions that can promote meaningful activity, stimulation and well-being, through an increase in positive emotions and an improvement in quality of life. The Engagement of a Person with Dementia Scale was developed based on current literature and previous research work on a video coding tool to ascertain the effect of psychosocial interventions on engagement in people with dementia. DESIGN/METHOD: Using the Delphi technique, the content validity of the scale was evaluated by 15 dementia experts and formal/informal dementia carers. Psychometric properties of the scale were evaluated using 131 videos of people with dementia presented with PARO-a therapeutic, interactive, robotic seal-in long-term aged care facilities. RESULTS: A 10-item scale was established following the rewording, combining and elimination of prospective items, with revisions made to the instructions for using and scoring the scale. An overall consensus with agreement for the scale was established among the panel of experts. The scale demonstrated robust internal consistency, inter-rater and test-retest reliability and convergent and discriminant validity. CONCLUSION: This study successfully developed the Engagement of a Person with Dementia Scale, with established content validity and psychometric properties. The scale assesses the behavioural and emotional expressions and responses of engagement by people with dementia when partaking in a psychosocial activity in five areas: affective, visual, verbal, behavioural and social engagement.

RESUMO

Skin-transmitted pathogens have threatened humans since ancient times. We investigated whether skin-transmitted pathogens were a subclass of disgust stimuli that evoked an emotional response that was related to, but distinct from, disgust and fear. We labelled this response "the heebie jeebies". In Study 1, coding of 76 participants' experiences of disgust, fear, and the heebie jeebies showed that the heebie jeebies was elicited by unique stimuli which produced skin-crawling sensations and an urge to protect the skin. In Experiment 2,350 participants' responses to skin-transmitted pathogen, fear-inducing, and disgust-inducing vignettes showed that the vignettes elicited sensations and urges which loaded onto heebie jeebies, fear, and disgust factors, respectively. Experiment 3 largely replicated findings from Experiment 2 using video stimuli (178 participants). Results are consistent with the notion that skin-transmitted pathogens are a subclass of disgust stimuli which motivate behaviours that are functionally consistent with disgust yet qualitatively distinct.

RESUMO

Theory proposes that interest is a positive emotion that may either broaden attention to facilitate processing of new information, or narrow attention to preserve engagement with new information. To our knowledge, no research has directly examined the effect of interest on attentional scope. Across four experiments, we show that traits associated with the propensity to experience interest-specifically, trait curiosity and internal boredom proneness-are associated with a narrower scope of attention. We also find that, instead of broadening, interest actually narrows attentional scope in comparison to a neutral state and awe. Challenging the conventional notion that all positive emotions broaden cognition and attention, our findings suggest that specific emotions influence attention in ways that extend beyond a general emotional valence effect.

RESUMO

The study of engagement in people with dementia is important to determine the effectiveness of interventions that aim to promote meaningful activity. However, the assessment of engagement for people with dementia in relation to our current work that uses social robots is fraught with challenges. The Video Coding - Incorporating Observed Emotion (VC-IOE) protocol that focuses on six dimensions of engagement: emotional, verbal, visual, behavioral, collective and signs of agitation was therefore developed. This paper provides an overview of the concept of engagement in dementia and outlines the development of the VC-IOE to assess engagement in people with dementia when interacting with social robots.
