Context extinction and associative learning in Lymnaea

Aerial respiratory behavior in the pond snail Lymnaea was operantly conditioned so that snails learned not to perform aerial respiration in a hypoxic environment. Snails were trained in either the standard context (no food odorant) or a carrot (food-odorant) context. An operant training procedure of two 45-min training sessions with a 1-h interval between the sessions followed by a third 45-min training session 18 h later was sufficient to produce associative learning and long-term memory (LTM) that persisted for at least 5 days. If, however, following the third operant training session snails received three 45-min extinction training sessions, with each extinction session separated by at least a 1-h interval, LTM was not observed when tested the following day. That is, the memory was extinguished. Extinction, however, did not occur if the context of the extinction training was different from the context of the associative training. That is, in the snails trained in the standard context, extinction did not occur if the extinction training sessions were performed in the food-odorant context and vice versa.     

Development and validation of the Self‐Gifting Consumer Behaviour scale

Self‐gifting consumer behaviour (SGCB) is on the rise as consumers seek reward and therapeutic benefits from their shopping experiences. SGCB is defined as personally symbolic, self‐communication through special indulgences, which tend to be premeditated and highly context bound. Prior research into the measurement of this growing behavioural phenomenon has been fragmented because of differences in conceptualisation. This research builds upon the prior literature and through a series of qualitative and quantitative studies, develops a valid, multidimensional measure of SGCB that will be useful for future quantitative inquiry into self‐gifting consumption.

Neighbourhood,school and family determinants of children's aspirations in primary school

Aspirations can be important for young children as well as adolescents. However, there is little research on the determinants of aspirations in young children. We carried out this study to investigate the early contextual (neighbourhood, school and family) determinants of occupational aspirations in primary school children. Our sample comprised children from the Millennium Cohort Study who lived in England in the beginning of our study period (n = 10,086; 5,126 boys). Occupational aspirations were measured at age 7 years, while their contextual determinants were measured in the previous data sweeps, at ages 3 and 5 years. We fitted structural equation models to test the role of family and neighbourhood socio-economic status (SES) and child ethnicity in predicting aspirations both directly and via their associations with parental involvement, household chaos, school-level achievement and child cognitive ability. We found that the only significant determinants of aspirations at age 7 years were family SES and ethnicity, and only in boys. Family SES and ethnicity were also related to parental involvement, household chaos, cognitive ability and school-level achievement, but none of these factors predicted aspirations. Supplementary analysis showed that family SES was a particularly powerful determinant of the aspirations of white compared to non-white boys.     

Some psychoanalytic reflections on the concept of dignity

After reviewing the pertinent philosophical and psychoanalytic writings on the concept of dignity, this paper proposes three categories of dignity. Conceptualized as phenomenological clusters, heuristic viewpoints, and levels of abstraction, these include (i) metaphysical dignity which extends the concept of dignity beyond the human species to all that exists in this world, (ii) existential dignity which applies to human beings alone and rests upon their inherent capacity for moral transcendence, and (iii) characterological dignity which applies more to some human beings than others since they possess a certain set of personality traits that are developmentally derived. The paper discusses the pros and cons of each category and acknowledges the limitations of such classification. It also discusses the multiple ways in which these concepts impact upon clinical work and concludes with some remarks on the relationship of dignity to choice, narcissism, and suicide.     

Train the child and teach the adult: Developing intervention strategies for increasing seafood consumption

Despite increasing levels of per capita seafood consumption globally, consumption levels across the population vary with many consumers eating less than recommended weekly intakes. This study investigates the influence of childhood patterns of seafood consumption, consumer confidence in selecting and preparing seafood, adult eating habits, and lifestyle on seafood consumption. Partial least squares structural equation modelling analysis was conducted using a sample of 1,318 Australian adults. The results show that consuming seafood regularly in childhood and developing the confidence to select and prepare seafood as an adult contribute to the development of seafood eating habits. Subsequently, a habit of consuming seafood leads to a lifestyle involving regular consumption of seafood. The results indicate the need to develop and implement intervention strategies for encouraging childhood seafood consumption (“train the child”) and increasing adults' confidence in selecting and preparing seafood (“teach the adult”). Intervention strategies proposed include educational programmes targeted at both children and adults, combined with the development of seafood products that appeal to children and suit the changing lifestyle needs of today's 21st century consumers.
