Segmentation of the major body axis into repeating units is arguably one of the major inventions in the evolution of animal body plan pattering. It is found in current day vertebrates, annelids and arthropods. Most segmented animals seem to use a clock-and-wavefront type mechanism in which oscillations emanating from a posterior growth zone become transformed into an anterior posterior sequence...

Having good intentions to engage in healthy behaviours, to change our lives in a positive direction and make substantial, lasting changes may not always translate into actions or behaviour that is maintained. Motivational Interviewing is a directive person-centred approach designed to explore ambivalence and activate motivation for change [Miller WR, Rollnick S. Motivational Interviewing: Prepa...

Methylmercury (MeHg) is a potent neurotoxin that in high exposures can cause mental retardation, cerebral palsy, and seizures. The developing brain appears particularly sensitive to MeHg. Exposure levels in pregnant experimental animals that do not result in detectable signs or symptoms in the mother can adversely affect the offspring's development. Studies of human poisonings suggest this may ...

False claims are a key feature of confabulation, delusion, and anosognosia. In this paper we consider the role of motivational factors in such claims. We review motivational accounts of each symptom and consider the evidence adduced in support of these accounts. In our view the evidence is strongly suggestive of a role for motivational factors in each domain. Before concluding, we widen the foc...

One form of cognitive control is the ability to resist temptation in favor of long-term goal-oriented behavior. Historically, the development of cognitive control capacity has been described by a linear function from infancy to adulthood. However, the context in which control is required impacts behavioral regulation abilities, such that emotionally charged or rewarding contexts can diminish co...

Using an unbiased place preference paradigm, opiate-naive rats were conditioned as follows: one side was paired with 18-h food deprivation, and the other environment was paired with 18-h food deprivation and morphine (20 mg/kg i.p.). On the test day, animals showed a large prefer· ence for the environment paired with hunger and morphine. The acquisition of this preference was unaffected by bila...

College students in STEM (science, technology, engineering, mathematics) disciplines are increasingly faced with highly competitive and demanding degree programs and are at risk of academic overconfidence. Following from theory and research highlighting the psychological and developmental risks of unrealistic expectations, the present exploratory study evaluated the longitudinal effects of a mo...
