The aim of this study was to investigate the association between false belief comprehension, the exhibition of pretend play and the use of mental state terms in pre-school children. Ferry children, aged between 36 and 54 months were videotaped engaging in free play with each parent. The exhibit-ion of six distinct acts of pretend play and the expression of 16 mental sr:ate terms were coded during play. Each child was also administered a pantomime task and three standard false belief casks. Reliable associations were also found between false belief performance and the pretence categories of object substitution and role assignment, and the exhibition of imaginary object pantomimes. Moreover, the use of mental state terms was positively correlated with false belief and the pretence categories of object substitution, imaginary play and role assignment, and negatively correlated with the exhibition of body part object pantomimes. These findings indicate that the development of a mental state lexicon and some, bur not all, components of pretend play are dependent on the capacity for metarepresentational cognition.

Background. Play is an indication of a children`s development. Purpose. Organize a culturally adapt the Child-Initiated Pretend Play Assessment to Brazilian population. Method. Translation and cultural adaptation procedures consisted of translation, synthesis, back translation, author`s approval, and pretest of the assessment. For the pretest, 14 typically developing children were assessed. Was evaluated the use of play materials, duration of the assessment, and reliability. Findings. Play materials and duration of the assessment were appropriate for Brazilian children. Analysis of intra-rater reliability showed good agreement ranging from 0.90 to 1.00. Inter-rater reliability showed good to moderate agreement for five items ranging from 0.76 to 0.59. Four items showed chance to poor agreement (rho = -0.13 to 0.50). Implications. Results of the pretest indicate the Brazilian version of the ChIPPA is potentially useful for Brazilian children. ChIPPA training in Portuguese in Brazil with play observation feedback is recommended to improve inter-rater reliability.

This preliminary study aims to investigate children’s ability to understand that the emotional expressions that occur in pretend play do not necessarily coincide with the emotions people feel inside. Previous research has found that children aged 4 and 6 have difficulty to distinguish between the external and the internal emotion of a character who pretends an emotion. In the present work, thirteen 4-year-olds and eight 6-year-olds were administered stories in which a character simulated an emotion. Differently from previous research, the questions addressed to the children did not focus on the distinction external/internal emotion but on the distinction between real/pretend emotion. Furthermore, since previous research has suggested that children may understand better selfpretence than pretence of others, the participants in our study were engaged in a pretence situation where they had to pretend to be happy. The results obtained showed that, contrary to previous research, most 4- and 6-year-olds realize that pretend emotions may not be real, and this was true both for self-pretence and for the pretence of others

The aim in the current study was to investigate the emergence of pretend play, mirror self-recognition, synchronic imitation and deferred imitation in normally developing human infants. A longitudinal study was conducted with 98 infants seen at three-monthly intervals from 12 through to 24 months of age. At each session the infants were tested on a range of tasks assessing the four target skills. Deferred imitation was found to emerge prior to synchronic imitation, pretend play and mirror self-recognition. In contrast, the latter three skills emerged between 18 and 21 months and followed similar developmental trajectories. Deferred imitation was found to hold a prerequisite relation with these three skills. Synchronic imitation, pretend play and mirror self-recognition were not closely associated and no prerequisite relations were found between these skills. These findings are discussed in the context of current theories regarding the development of pretend play, mirror self-recognition, synchronic imitation and deferred imitation in the second year.

Arriving in Brisbane some six years ago, I could not help being impressed by what may be prosaically described as its atmospheric amenity resources. Perhaps this in part was due to my recent experiences in major urban centres in North America, but since that time, that sparkling quality and the blue skies seem to have progressively diminished. Unfortunately, there is also objective evidence available to suggest that this apparent deterioration is not merely the result of habituation of the senses. Air pollution data for the city show trends of increasing concentrations of those very substances that have destroyed the attractiveness of major population centres elsewhere, with climates initially as salubrious. Indeed, present figures indicate that photochemical smog in unacceptably high concentrations is rapidly becoming endemic also over Brisbane. These regrettable developments should come as no surprise. The society at large has not been inclined to respond purposefully to warnings of impending environmental problems, despite the experiences and publicity from overseas and even from other cities within Australia. Nor, up to the present, have certain politicians and government officials displayed stances beyond those necessary for the maintenance of a decorum of concern. At this stage, there still exists the possibility for meaningful government action without the embarrassment of losing political favour with the electorate. To the contrary, there is every chance that such action may be turned to advantage with increased public enlightenment. It would be more than a pity to miss perhaps the final remaining opportunity: Queensland is one of the few remaining places in the world with sufficient resources to permit both rational development and high environmental quality. The choice appears to be one of making a relatively minor investment now for a large financial and social gain the near future, or, permitting Brisbane to degenerate gradually into just another stagnated Los Angeles or Sydney. The present monograph attempts to introduce the problem by reviewing the available research on air quality in the Brisbane area. It also tries to elucidate some seemingly obvious, but so far unapplied management approaches. By necessity, such a broad treatment needs to make inroads into extensive ranges of subject areas, including political and legal practices to public perceptions, scientific measurement and statistical analysis to dynamics of air flow. Clearly, it does not pretend to be definitive in any of these fields, but it does try to emphasize those adjustable facets of the human use system of natural resources, too often neglected in favour of air pollution control technology. The crossing of disciplinary boundaries, however, needs no apology: air quality problems are ubiquitous, touching upon space, time and human interaction.

An experiment explored the hypothesis that inhibitory ability helps people stop themselves from engaging in socially inappropriate behavior. All participants completed a Stroop color-naming task, after which half of the participants were asked to remember an eight-digit number (inducing divided attention). Participants were then offered an unfamiliar and visually unappetizing food product (a chicken foot) under conditions of either low or high social pressure to pretend that it was appealing. Participants who had full attention available and were under pressure to pretend the food was appealing were least likely to emit a negative response, and performance on the Stroop task predicted the degree to which they successfully restrained negative responses. These results suggest that the cognitive ability to inhibit unwanted information facilitates socially appropriate behavior.

Recent interest in the development and evolution of theory of mind has provided a wealth of information about representational skills in both children and animals, According to J, Perrier (1991), children begin to entertain secondary representations in the 2nd year of life. This advance manifests in their passing hidden displacement tasks, engaging in pretense and means-ends reasoning, interpreting external representations, displaying mirror self-recognition and empathic behavior, and showing an early understanding of mind and imitation. New data show a cluster of mental accomplishments in great apes that is very similar to that observed in 2-year-old humans. It is suggested that it is most parsimonious to assume that this cognitive profile is of homologous origin and that great apes possess secondary representational capacity. Evidence from animals other than apes is scant. This analysis leads to a number of predictions for future research.

O tecido adiposo é um órgão endócrino dinâmico, secretando factores importantes na regulação do metabolismo, fluxo vascular sanguíneo e linfático, e função imunológica, entre outros. Em caso de acumulação de tecido adiposo por ingestão de uma dieta gorda, ou por disfunção metabólica, os adipócitos podem desencadear uma reacção inflamatória por falha na drenagem linfática, acumulando-se mediadores inflamatórios, os quais potenciam a propagação da reacção. Assim, questiona-se uma potencial associação entre o aumento de tecido adiposo na obesidade, hipóxia adipocitária e estimulação da linfangiogénese. Além disso, a expressão de adipocinas varia de acordo com a distribuição do tecido adiposo (subcutâneo, TAS e visceral, TAV). Deste modo, pretende-se com este estudo contribuir para o aumento do conhecimento sobre os complexos mecanismos moleculares subjacentes à linfangiogénese. Ensaios com ratinhos da estirpe C57Bl/6J (modelo de obesidade) e BALB/c (modelo de asma e obesidade), divididos em grupos submetidos a dieta normal e dieta rica em gordura. Avaliação semi-quantitativa da expressão tecidular de LYVE-1 (marcador da linfangiogénese) por imunohistoquímica em material embebido em parafina, no TAS e TAV, e cromatografia líquida de ultra-performance acoplada de espectrometria de massa (UPLC-MS) para análise da expressão plasmática de ceramida e esfingosina-1-fosfato (S1P). No modelo de obesidade observou- -se diminuição do número de vasos linfáticos e expressão de LYVE-1 ao longo do tempo no TAV, e aumento de ambos os parâmetros e hipertrofia adipocitária no TAS. As concentrações de ceramida e S1P corroboram a existência de um processo inflamatório nos ratinhos em estudo, ainda que numa fase muito inicial. No modelo de asma e obesidade, após 17 semanas de tratamento, observou-se incremento da linfangiogénese no TAV, mas não no TAS. A resposta inflamatória avaliada através dos diferentes parâmetros permite afirmar que num estadio inicial de obesidade a proliferação linfática poderá estar a ser retardada pela hipertrofia adipocitária. A libertação de adipocinas será observada apenas numa fase posterior, desencadeando todo o processo inflamatório que incrementará a proliferação linfática. Adicionalmente, é possível sugerir que a maior pressão à qual o TAV se encontra sujeito não favorece a proliferação linfática, pelo menos num estadio incial.
