The Influence of Child Gender on the Prospective Relationships between Parenting and Child ADHD

The aims of the current study were to (i) explore the potential bidirectional, prospective relationships between parenting and child ADHD, and (ii) explore whether these relationships differed on the basis of child gender. Data were obtained from waves 1 (children aged 4- to 5-years) to 5 (children aged 12- to 13-years) of the Longitudinal Study of Australian Child (LSAC) dataset (child cohort). In order to examine dimensions of both mothers’ and fathers’ parenting, a subsample of nuclear families with mothers, fathers and children present at all waves was extracted (final sample = 1932; sons = 981, daughters = 951). Child ADHD measures included the hyperactive-impulsive subscale of the strengths and difficulties questionnaire for symptoms, and parent-report question for diagnosis. Mothers and fathers completed scales on dimensions of Angry, Warm and Consistent Parenting. A cross-lagged panel model demonstrated (i) higher child ADHD symptoms at wave 1 led to a global increase in less-than-optimal parenting at wave 2, and (ii) child ADHD symptoms and Angry Parenting shared a prospective, bi-directional relationship (whereby increases in one predicted increases in the other over time) during earlier years of development. Latent growth curve models demonstrated that increases in Angry Parenting across time were significantly predicted by increases in child ADHD symptoms. A logistic regression demonstrated that both mothers’ and fathers’ Angry Parenting at wave 1 significantly predicted an ADHD diagnosis in children at wave 3. No predictive relationships differed between child genders; thus, it appears these prospective pathways are similar for both sons and daughters.     

Learning nonwords: the Hebb repetition effect as a model of word learning

Page and Norris [(2008). Is there a common mechanism underlying word-form learning and the Hebb repetition effect? Experimental data and a modelling framework. In A. Thorn &; M. P. A. Page (Eds.), Interactions between short-term and long-term memory in the verbal domain; (2009). A model linking immediate serial recall, the Hebb repetition effect and the learning of phonological word forms. Philosophical Transactions of the Royal Society B: Biological Sciences, 364(1536), 3737–3753. doi:10.1098/rstb.2009.0173] have suggested that the Hebb [(1961). Distinctive features of learning in the higher animal. In J. F. Delafresnaye (Ed.), Brain mechanisms and learning (pp. 37–46). Oxford: Blackwell] repetition paradigm can be considered as a laboratory analogue of word learning. In Hebb learning experiments, the lists of items to be learned are presented as discrete sequences. In contrast, novel words are, by definition, always heard as a single coarticulated whole. Might this undermine the claim that Hebb learning can shed light on word learning? Here we report an experiment comparing learning sequences of isolated syllables with learning the same sequences spoken as a single coarticulated nonword. The pattern of learning was similar in the two cases, suggesting that the Hebb repetition paradigm can indeed provide valuable insights into the way novel word forms are learned.     

Producing the Post-Fordist Public: The Political Economy of Public Engagement with Science

The commercial exploitation of scientific knowledge and increased public participation in democratic decision-making about science and technology have emerged as the two central themes of contemporary science policy in Britain. We argue that the prominence of participatory discourse in contemporary science policy is primarily due to the close fit of this discourse with the post-Fordist and post-industrial economic strategy of the British state. Participation is a form of immaterial labour which gains currency in this phase of capitalism, blurring the distinctions between production and consumption, and between the economy and the political or communicative public sphere. Participation is cognitive, interpretative, affective, and social work which enters into the construction of technologies as bundled material artefacts and cultural meanings. Participation operates both in the production and consumption of goods and in the legitimation of social and political relations. Public engagement exercises prepare the product for the market and the market for the product. Such exercises therefore instantiate the way in which immaterial labour is both productive and political. Participation activates, but also disciplines, the subjectivities of post-Fordist publics. Contrary to the rhetoric of democratization that has accompanied public engagement efforts, these programmes potentially operate as forms of control and co-optation, and promote the shaping of publics as markets.     

Olfactory working memory: exploring the differences in n-back memory for high and low verbalisable odorants

ABSTRACT

We describe four experiments each examining n-back performance for high and low verbalisable odorants. Participants were presented with a sequence of odorants and were required to state if the current odorant was the same or different to the odorant presented two items earlier. Experiment 1 reported superior performance for high, relative to low, verbalisable odorants and was evident despite above-chance memory performance for the low verbalisable odorants. Experiment 2 showed that such superiority persisted with a concurrent articulation condition, suggesting that the memory benefit was not a consequence of verbal recording and rehearsal. Experiment 3 employed metacognitive judgments and showed that correct 2-back responses for high verbalisable odorants received more recollection responses compared to low verbalisable odorants. Experiment 4 compared n-back performance across different stimulus types and showed that, for high verbalisable odorants, performance correlated with both letters and abstract shapes, but such correlations were absent for low verbalisable odorants. Taken together, these findings show differences in n-back performance between high and low verbalisable odorants, and show that high verbalisable odorants exhibit performance similarities with both verbal and visual stimuli. We further argue that n-back performance for low verbalisable odorants operates differently to that of high verbalisable odorants.     

There is more to life stories than memories

Current theories focus on the role of specific memories in organising the life story. However, temporally extended structures of autobiographical memory, like lifetime periods and mini-narratives (here termed chapters), may also play a central role in the organisation of the life story. Here, 30 elderly participants were asked to tell their life story in a free format. The life stories were divided into components and coded as chapters, specific memories, categoric memories, facts, chapters about other people, and autobiographical reasoning categories, i.e., reflections, evaluations, life lessons, and inferences about personality. The results show that chapters were much more common than specific memories in the life stories, indicating that chapters may play a role in the structuring of life stories. The number of chapters and specific memories in the life stories were unrelated, suggesting that the recounting of chapters versus specific memories does not reflect a preferred recall style.     

Book and Website Reviews

Using practicing sales managers as subjects, the results indicate that personal characteristics of gender and weight may be used in making disciplinary judgments following episodes of a particular type of unacceptable work behavior, an unethical selling act. As hypothesized, saleswomen were disciplined less severely while overweight salespeople were disciplined more severely. However, being overweight produced harsher discipline for saleswomen but had no effect on salesmen. A stated organizational policy about the particular type of unacceptable behavior used did bring about more equal treatment for those described as overweight but did not even out the discipline administered to men and women.     

Editorial: Psychosocial Aspects of AIDS

This article comprises two parts.

In the first part, some general issues related to research training are discussed, including the “Scientist-Practitioner Model,” training for basic and applied research, differences between the USA and Europe at various levels of training, and types or areas of research students should be trained for.

In the second part, seven specific objectives of research training are discussed. These objective are (a) learning to write a review of the research literature, (b) learning to critically evaluate a journal article, (c) learning to plan and carry out a specific health psychology research study, (d) learning to communicate, (e) learning to enhance co-operation of professionals in the field, (f) learning to raise funds, (g) learning to respect ethical issues.
