The influence of parental alcohol expectancies on offsprings' alcohol expectancies and drinking: A longitudinal study. It has been shown that potentially modifiable alcohol related cognitions, such as alcohol expectancies (AE)and drinking refusal self-efficacy (DRSE) are formed in childhood are related to drinking in adolescents and adults. The question of how these beliefs are formed is still unanswered. This longitudinal study examines the influences of parental alcohol-related beliefs and ....The influence of parental alcohol expectancies on offsprings' alcohol expectancies and drinking: A longitudinal study. It has been shown that potentially modifiable alcohol related cognitions, such as alcohol expectancies (AE)and drinking refusal self-efficacy (DRSE) are formed in childhood are related to drinking in adolescents and adults. The question of how these beliefs are formed is still unanswered. This longitudinal study examines the influences of parental alcohol-related beliefs and drinking, on children's alcohol-related beliefs and drinking behaviour. Positive results of this study will improve primary prevention by identifying and changing modifiable variables for populations potentially at-risk of developing later alcohol-related. It will also help to reduce cost and suffering of a major problem in Ausstralia.

Improving the retention rate for residential treatment of substance abuse by sequential intervention for social anxiety. Alcohol and other drug use is a major social and medical problem, costing the Australian community an estimated $7.6 billion annually. Mental health disorders have been closely linked with increased illicit drug use and physical health problems. Social anxiety (SAD) is highly prevalent amongst individuals presenting with drug and alcohol use disorders. Evidence suggests that ....Improving the retention rate for residential treatment of substance abuse by sequential intervention for social anxiety. Alcohol and other drug use is a major social and medical problem, costing the Australian community an estimated $7.6 billion annually. Mental health disorders have been closely linked with increased illicit drug use and physical health problems. Social anxiety (SAD) is highly prevalent amongst individuals presenting with drug and alcohol use disorders. Evidence suggests that social anxiety symptoms may be responsible for promoting excessive drug use and may be a particularly influential factor in poor treatment retention rates and promoting relapse. Thus, the focus on improving treatment outcomes for individuals with comorbid anxiety and drug use disorders represents an area of considerable importance both nationally and internationally.Read moreRead less
When is extinction not extinction? Disorders of fear and anxiety are widespread and impose significant burdens on individual sufferers and their families. This projects studies new ways of augmenting loss of fear and will identify the important behavioural mechanisms as well as critical brain pathways for this fear loss.
The initiation, development, and maintenance of alcohol/tobacco use in adolescents: The role of associative memory. Alcohol abuse and tobacco misuse are common in Australian adolescents and its long-term health consequences are well established. Models of drug-related memory association predict drug use in adults. However, memory association models have not been applied to smoking behaviour, or to understanding adolescent alcohol/tobacco use over time. It is expected that memory associations ....The initiation, development, and maintenance of alcohol/tobacco use in adolescents: The role of associative memory. Alcohol abuse and tobacco misuse are common in Australian adolescents and its long-term health consequences are well established. Models of drug-related memory association predict drug use in adults. However, memory association models have not been applied to smoking behaviour, or to understanding adolescent alcohol/tobacco use over time. It is expected that memory associations will predict the development of alcohol/tobacco use and misuse, after accounting for viable alternative explanations of the association. Understanding the role that memory associations have in the development of alcohol/tobacco use should inform prevention programs for at-risk adolescents.Read moreRead less
Investigating memory reliability in intoxicated witnesses of crime. Eyewitness testimony is a crucial piece of evidence for solving a crime. Inaccurate testimony leads to miscarriages of justice such as failed prosecutions or false convictions. Many witnesses and victims are affected by alcohol or other drugs during the crime. This project brings together a multidisciplinary team aiming to improve understanding of how intoxication with different substances affects the reliability of victim and w ....Investigating memory reliability in intoxicated witnesses of crime. Eyewitness testimony is a crucial piece of evidence for solving a crime. Inaccurate testimony leads to miscarriages of justice such as failed prosecutions or false convictions. Many witnesses and victims are affected by alcohol or other drugs during the crime. This project brings together a multidisciplinary team aiming to improve understanding of how intoxication with different substances affects the reliability of victim and witness memory accuracy. Crucially, crimes are frequently distressing; therefore the interaction between intoxication and stress urgently requires exploration. This project will significantly advance our understanding of key mechanisms behind drug effects on memory, and support fairer judicial outcomes for all. Read moreRead less
The associative mechanisms underlying extinction and latent inhibition. Formal models that explain how animals learn associations between stimuli have enjoyed considerable success, and have even been identified with neurophysiological mechanisms. Theoretical analysis of the opposite, though equally important, form of learning - that two stimuli are not associated - lags far behind, due to fundamental methodological confounds that plague research on this topic. This project investigates two insta ....The associative mechanisms underlying extinction and latent inhibition. Formal models that explain how animals learn associations between stimuli have enjoyed considerable success, and have even been identified with neurophysiological mechanisms. Theoretical analysis of the opposite, though equally important, form of learning - that two stimuli are not associated - lags far behind, due to fundamental methodological confounds that plague research on this topic. This project investigates two instances of this learning: extinction and latent inhibition. Using a new procedure that avoids earlier confounds, we will describe and compare the processes underlying extinction and latent inhibition. This research will represent a major breakthrough in our understanding about fundamental processes in learning.Read moreRead less
Uncertainty and response control in the prefrontal cortex. This project will identify how complex behaviours come to be performed habitually. It is proposed that statistical certainty in the learning environment is a key determinant of automatic behaviour, that detection of uncertainty can restore voluntary control of behaviour and that this is an important function of the prefrontal cortex of the brain.
Models of adolescent drug use and its consequences. Recent concerns surround the impact of drug abuse - particularly binge drinking, inhalant abuse and cannabis use - on the mental health of adolescents. Early drug use is associated with mental health problems although the mechanisms involved are not well characterised. The present proposal aims to use animal models to characterise substance abuse that occurs during the adolescent period and to investigate its effects on brain and behaviour. Inc ....Models of adolescent drug use and its consequences. Recent concerns surround the impact of drug abuse - particularly binge drinking, inhalant abuse and cannabis use - on the mental health of adolescents. Early drug use is associated with mental health problems although the mechanisms involved are not well characterised. The present proposal aims to use animal models to characterise substance abuse that occurs during the adolescent period and to investigate its effects on brain and behaviour. Increasing our knowledge of the causes and consequences of adolescent drug abuse will improve Australia's ability to confront this problem and to develop early interventions and treatments that minimise associated harms.Read moreRead less
Can parents teach their children to drink alcohol responsibly? Or, is one drop a drop too many? Parents typically supply alcohol to their children believing it is the best way to teach responsible drinking. Whether parents should provide alcohol is controversial and the evidence to inform this decision is unclear. This research will provide an in-depth understanding of the consequences of parents providing alcohol to their children and when, where and how this can be done to minimise harm. This ....Can parents teach their children to drink alcohol responsibly? Or, is one drop a drop too many? Parents typically supply alcohol to their children believing it is the best way to teach responsible drinking. Whether parents should provide alcohol is controversial and the evidence to inform this decision is unclear. This research will provide an in-depth understanding of the consequences of parents providing alcohol to their children and when, where and how this can be done to minimise harm. This is a national priority as alcohol abuse is a leading cause of injury and death among young Australians and developing the knowledge for preventive health care is essential. This research will provide parents with the information they need to give their children a healthier start to life.Read moreRead less
Age-dependent effects of cannabinoids on emotion, cognition and vulnerablity to addiction. Cannabis is the most widely used illicit drug in Australia so understanding the effects of this drug is of great importance. There is little of no basic research on cannabis currently occurring in Australia. Yet such research is critical in resolving the ambiguities and difficulties inherent in our understanding of the drug. The importance of increasing our understanding of the long-term effects of the dr ....Age-dependent effects of cannabinoids on emotion, cognition and vulnerablity to addiction. Cannabis is the most widely used illicit drug in Australia so understanding the effects of this drug is of great importance. There is little of no basic research on cannabis currently occurring in Australia. Yet such research is critical in resolving the ambiguities and difficulties inherent in our understanding of the drug. The importance of increasing our understanding of the long-term effects of the drug on young developing brains is particularly evident. The information gained in the current project will serve to inform medical and scientific communities, government policy makers, as well as the broader Australian community. Read moreRead less
