Early indications of delayed cognitive development in preschool children born very preterm: evidence from domain‐general and domain‐specific tasks

Cognitive impairment often follows preterm birth but its early underlying nature is not well understood. We used a novel approach by investigating the development of colour cognition in 54 very preterm children born ?30 weeks gestational age without severe neurosensory impairment and 37 age‐matched term‐born controls, aged 2–5 years. Quantitative and qualitative differences in the development of colour cognition are well charted throughout the preschool years, enabling delayed from deviant development to be determined. Standardized domain‐general and experimental colour‐specific tests of language, attention, and memory were employed. Very preterm children showed significantly depressed language than term controls, with very preterm group girls significantly outperforming boys. Very preterm children also showed poorer attention and memory than term controls, but not significantly so. Importantly, colour‐specific tests showed qualitatively similar performance, but for naming and executive planning quantitatively poorer performance, across groups, indicating typical but delayed development. Hence, even before school entry, compared with term‐born peers, very preterm children show delayed development of cognitive processes that underpin later scholastic abilities, but the nature by which these processes operate appears to be typical of term children. If left untreated these early developmental delays may underpin later deviations from the typical developmental trajectory. Copyright © 2010 John Wiley & Sons, Ltd.     

From Psychoanalysis to a Post-Foulkesian Group Analysis

This paper explores the relationship between individual psychoanalytic theory and that of Foulkesian group analytic theory. It traces some of the philosophical and metaphysical assumptions behind orthodox psychoanalytic theory, and discusses its implications for group analytic theory. The paper then describes some aspects of a post-Foulkesian group analytic theory which challenge these assumptions and argues for the socio-political to be given a constitutive role in the construction of the psyche.     

Colour-cueing in visual search

Several studies have shown that people can selectively attend to stimulus colour, e.g., in visual search, and that preknowledge of a target colour can improve response speed/accuracy. The purpose was to use a form-identification task to determine whether valid colour precues can produce benefits and invalid cues costs. The subject had to identify the orientation of a "T"-shaped element in a ring of randomly-oriented "L"s when either two or four of the elements were differently coloured. Contrary to Moore and Egeth's (1998) recent findings, colour-based attention did affect performance under data-limited conditions: Colour cues produced benefits when processing load was high; when the load was reduced, they incurred only costs. Surprisingly, a valid colour cue succeeded in improving performance in the high-load condition even when its validity was reduced to the chance level. Overall, the results suggest that knowledge of a target colour does not facilitate the processing of the target, but makes it possible to prioritize it.     

Paradise Regained: A Non-Reductive Realist Account of the Sensible Qualities

This paper defends a non-reductive realist view of the sensible qualities—roughly, the view that the sensible qualities are (i) really instantiated by the external objects of perception, and (ii) not reducible to response-independent physical properties or response-dependent relational properties. I begin by clarifying and motivating the non-reductive realist view. I then consider some familiar difficulties for the view. Addressing these difficulties leads to the development and defence of a general theory, inspired by Russellian Monist theories of consciousness, of how the sensible qualities (especially the so-called ‘secondary qualities’) relate to physical reality. I conclude by showing how this theory, which I call ‘Secondary Quality Russellian Monism’, resolves the most significant difficulties for the non-reductive realist view of the sensible qualities.     

Influencing health decision-making: A study of colour and message framing

Objective: Previous research has provided evidence that colour associations and frame can influence behavioural intentions to engage in vaccination behaviours. In this study, the extension of these effects to sunscreen application behaviours was investigated. Additional colours and the manner in which colour primes were employed were also explored.

Design: Two hundred and eighty-six college students were primed with either short wavelength colours (blue/purple) or long wavelength colours (red/orange) as part of goal framed sunscreen information pamphlets.

Main outcome measures: Self-reported behavioural intentions to apply sunscreen, immediate affective reaction to stimuli material, anticipated affect towards sunscreen use, and perceived efficacy of preventing skin cancer were measured.

Results: Individuals with no prior intention to use sunscreen expressed greater behavioural intentions to do so after reading a positively framed sunscreen pamphlet that was designed using short wavelength colours. The negatively framed messages and those presented in long wavelength colours did not enhance persuasion.

Conclusions: In accordance with the Unification Theory of Framing, a match between the representations of the target behaviour, the colour prime, and the frame resulted in the greatest amount of persuasion. Creating communications with representations that match the target behaviour could be a powerful tool to increase compliance.     

Encounter with Gerard Chrzanowski

Gerard Chrzanowski was a prominent representative of psychoanalysis. However, he was not a friend of strict delimitations between the different psychoanalytic schools and the struggles between them. Having grown up in Poland, having lived a few years in Switzerland and the rest of his life in USA he had a multi-cultural background. He was with that well prepared to exert an integrative role between the different psychoanalytic movements and especially in the International Federation of Psychoanalysis, of which he was one of the founders and honourable members.     

Fruit over sunbed: Carotenoid skin colouration is found more attractive than melanin colouration

Skin colouration appears to play a pivotal part in facial attractiveness. Skin yellowness contributes to an attractive appearance and is influenced both by dietary carotenoids and by melanin. While both increased carotenoid colouration and increased melanin colouration enhance apparent health in Caucasian faces by increasing skin yellowness, it remains unclear, firstly, whether both pigments contribute to attractiveness judgements, secondly, whether one pigment is clearly preferred over the other, and thirdly, whether these effects depend on the sex of the face. Here, in three studies, we examine these questions using controlled facial stimuli transformed to be either high or low in (a) carotenoid colouration, or (b) melanin colouration. We show, firstly, that both increased carotenoid colouration and increased melanin colouration are found attractive compared to lower levels of these pigments. Secondly, we show that carotenoid colouration is consistently preferred over melanin colouration when levels of colouration are matched. In addition, we find an effect of the sex of stimuli with stronger preferences for carotenoids over melanin in female compared to male faces, irrespective of the sex of the observer. These results are interpreted as reflecting preferences for sex-typical skin colouration: men have darker skin than women and high melanization in male faces may further enhance this masculine trait, thus carotenoid colouration is not less desirable, but melanin colouration is relatively more desirable in males compared to females. Taken together, our findings provide further support for a carotenoid-linked health-signalling system that is highly important in mate choice.     

Context-dependent effects of background colour in free recall with spatially grouped words

Three experiments investigated context-dependent effects of background colour in free recall with groups of items. Undergraduates (N=113) intentionally studied 24 words presented in blocks of 6 on a computer screen with two different background colours. The two background colours were changed screen-by-screen randomly (random condition) or alternately (alternation condition) during the study period. A 30-second filled retention interval was imposed before an oral free-recall test. A signal for free recall was presented throughout the test on one of the colour background screens presented at study. Recalled words were classified as same- or different-context words according to whether the background colours at study and test were the same or different. The random condition produced significant context-dependent effects, whereas the alternation condition showed no context-dependent effects, regardless of whether the words were presented once or twice. Furthermore, the words presented on the same screen were clustered in recall, whereas the words presented against the same background colour but on different screens were not clustered. The present results imply: (1) background colours can cue spatially massed words; (2) background colours act as temporally local context; and (3) predictability of the next background colour modulates the context-dependent effect.
