Hypoalgesia and fear co-occurred in rats trained on a heated floor and tested for their latencies to paw lick on that floor and to step down onto a nonheated floor. These responses were extinguished, suggesting a mediation by aversive conditioning processes. A benzodiazepine impaired the acquisition of aversive conditioning, but it did not attenuate the expression of conditioned hypoalgesia. The opioid agonist morphine also impaired acquisition across a range of drug doses and variations in hypoalgesic tolerance, whereas the opioid antagonist naloxone facilitated acquisition. The results are discussed in terms of the perceptual-defensive-recuperative (Fanselow, 1986) and working memory (Grau, 1987) models of the mechanisms for the co-occurrence of conditioned hypoalgesia and fear.

Tobacco smoking is a major health issue for Indigenous Australians, however there are few interventions with demonstrated efficacy in this population. The Transtheoretical Model may provide a useful framework for describing smoking behaviour and assessing readiness to quit, with the aim of developing better interventions. Interviews were conducted with 593 Indigenous Australians in eight rural and remote communities in north Queensland, to examine stages of change and smoking behaviour. Among current smokers, 39.6% and 43.4% were in Precontemplation and Contemplation stages respectively. A further 13.9% were making preparations to quit (Preparation) whilst only 3.2% said they were actively trying to quit (Action). When analysed by stage of change, the pattern of smoking-related behaviours conformed to the results of past research using the model. Importantly however, distribution of individuals across the stages opposes those observed in investigations of smoking behaviour in non-Indigenous Australian populations. The Transtheoretical Model can be used to meaningfully classify Indigenous smokers in remote north Queensland according to stages along the behaviour change continuum. Importantly, in this large sample across eight communities, most Indigenous smokers were not making preparations to change their smoking behaviour. This suggests that interventions should focus on promoting movement toward the Preparation and Action stages of change.

Three experiments exposed rats (Rattus norvegicus) to a discriminative conditioning procedure whereby a specific fluid was followed by lithium in one environment but not in another. This produced context-specific aversion to water, as detected by 2-bottle tests in Experiment 1, and a context-dependent saccharin aversion, which was unaffected by context extinction, in Experiment 2. Experiment 3 found that sucrose preexposure increased contextual control over the aversion established by sucrose-lithium pairings but had no effect on the target context. By contrast, target context exposure during conditioning reduced aversion to this context but did not affect contextual control of the sucrose aversion. In conclusion, depending on the conditioning procedures, contextual control of a taste aversion can be independent of the context's Pavlovian properties.

Objective Addressing the continued health disparities between Australia's Indigenous and non‐Indigenous peoples requires a multi‐sector approach in which the discipline of psychology has a central role. These disparities are partially driven by a lack of culturally appropriate methods of health delivery. This study aimed to explore urban Aboriginal and Torres Strait Islanders’ perceptions of health and wellbeing through social emotional wellbeing and strengths‐based frameworks. Methods A qualitative study was conducted with 19 urban Australian Aboriginal and Torres Strait Islander people. Data was collected via individual semi‐structured interviews and focus groups. Thematic analysis was conducted to identify strengths‐based themes within the data. Results Several attributes and values emerged from participants’ understandings of enhancing mental health and wellbeing. These included acceptance, respect, forgiveness and integrity, honesty, courage, empathy, mindfulness, and spirituality. Conclusions There are similarities between the central tenets of the strengths‐ and values‐based frameworks and a model of social emotional wellbeing. It is important to note that these attributes and values are understood at the individual, community, and cultural level. Each of these attributes and values are intricately linked to being mentally healthy and having strong cultural identity. These similarities may provide an avenue for shared cross‐cultural understandings and knowledges of mental health and wellbeing that will support culturally appropriate service delivery.

This research lends insight into the complexity of stressors for farming families and has implications for occupational health and mental health programs that seek to reduce stress and improve health outcomes for that group.
