Truth is in the eye of the beholder: Perception of the Müller-Lyer illusion in dogs

Visual illusions are objects that are made up of elements that are arranged in such a way as to result in erroneous perception of the objects’ physical properties. Visual illusions are used to study visual perception in humans and nonhuman animals, since they provide insight into the psychological and cognitive processes underlying the perceptual system. In a set of three experiments, we examined whether dogs were able to learn a relational discrimination and to perceive the Müller-Lyer illusion. In Experiment 1, dogs were trained to discriminate line lengths using a two-alternative forced choice procedure on a touchscreen. Upon learning the discrimination, dogs’ generalization to novel exemplars and the threshold of their abilities were tested. In the second experiment, dogs were presented with the Müller-Lyer illusion as test trials, alongside additional test trials that controlled for overall stimulus size. Dogs appeared to perceive the illusion; however, control trials revealed that they were using global size to solve the task. Experiment 3 presented modified stimuli that have been known to enhance perception of the illusion in other species. However, the dogs’ performance remained the same. These findings reveal evidence of relational learning in dogs. However, their failure to perceive the illusion emphasizes the importance of using a full array of control trials when examining these paradigms, and it suggests that visual acuity may play a crucial role in this perceptual phenomenon.     

Gender differences and styles in the use of digital games

This paper reports work in progress investigating gender differences and styles in the use of digital games amongst advanced level biology students. It is an elaboration on previous work exploring the relationship between cognitive style and academic performance in Maltese students taking biology at advanced level. In this previous work the cognitive style of 581 (212 male and 369 female) advanced biology students was correlated with their academic performance in five different subjects. Pearson's correlation showed that the wholist–analytic dimension, the verbal–imagery dimension, and gender were not correlated. Regression analysis showed that none of the style dimension combinations had a significant effect on performance in any of the subjects. However, gender proved to be a stronger determinant of performance. These results were interpreted from a cognitive neuroscience perspective. Numerous studies have consistently found gender differences in language and visuospatial skills. Female superiority is seen on tests of both receptive and productive language, and on more complex tasks such as making analogies and creative writing. Males have an advantage in visuospatial reasoning, being more adept at performing disembedding and internal spatial transformations. In view of these results and the constantly reported gender difference in the use of digital games, this paper describes the initial stage of an investigation about gender‐determined propensities to digital media. Different studies claim that males dedicate more time than female students to playing digital games. A marked emphasis on the use of particular game genres by the different sexes is also reported. This reported phenomenon is investigated within the context of Maltese students taking advanced biology. Through a questionnaire, data were collected about the time students spend playing digital games, their preferred platform, and their preferred games. Data were analysed to establish gender differences in the time spent on playing digital games, the preferred platform, the most popular digital games amongst males and female students, and the preferred game genre. The results are interpreted from neurocognitve and psychosocial perspectives. Suggestions are made for possible integration of digital games in learning.     

Building professionalism and employability skills: embedding employer engagement within first-year computing modules

This paper outlines a means of improving the employability skills of first-year university students through a closely integrated model of employer engagement within computer science modules. The outlined approach illustrates how employability skills, including communication, teamwork and time management skills, can be contextualised in a manner that directly relates to student learning but can still be linked forward into employment. The paper tests the premise that developing employability skills early within the curriculum will result in improved student engagement and learning within later modules. The paper concludes that embedding employer participation within first-year models can help relate a distant notion of employability into something of more immediate relevance in terms of how students can best approach learning. Further, by enhancing employability skills early within the curriculum, it becomes possible to improve academic attainment within later modules.     

Gender Stereotyping and Affective Attitudes Towards Science in Chinese Secondary School Students

This study explores explicit and implicit gender‐science stereotypes and affective attitudes towards science in a sample of Chinese secondary school students. The results showed that (1) gender‐science stereotyping was more and more apparent as the specialization of science subjects progresses through secondary school, becoming stronger from the 10th grade; girls were more inclined to stereotype than boys while this gender difference decreased with increasing grade; (2) girls tend to have an implicit science‐unpleasant/humanities‐pleasant association from the 8th grade, while boys showed a negative implicit attitude towards science up to the 11th grade. In self‐report, girls preferred humanities to science, while boys preferred science to humanities; (3) implicit affective attitude was closely related to implicit stereotype. In particular, implicit affective attitude has a stronger predictive power on stereotype than the other way around, the result of which may have more significance for girls.     

Re‐presenting women and leadership: a methodological journey

Research on women's leadership has tended to focus upon detailed micro studies of individual women's identity formation or, alternatively, to conduct macro studies of its broader discursive constructions within society. Both approaches, although providing helpful understandings of the issues surrounding constructions of women's leadership, are inadequate. They fail to deal with the ongoing dilemma raised in both Cultural Studies and studies of discourse and identity, in relation to the negotiation of subjectivity and representation, that is, how broader societal discourses and media representations of women's leadership both inform, and are informed by, the lived experiences of individual women. In this article, a range of methodological approaches are outlined that were drawn upon in a study of a small group of senior women academics from ethnically and socioeconomically diverse origins. The authors examine how the women negotiated the frequent mismatch that arose between, on the one hand, societal discourses and media representations which often reproduced narrow and highly stereotypical accounts of women's leadership, and on the other hand, the individual women's subjective experiences of leadership which challenged such representations. It is contended that it is necessary to draw on a number of methodological perspectives in ways which trouble and unsettle homogenized versions of women's leadership in order to fully explicate more nuanced and complex ways of understanding how women's leadership identity is formed.     

Provision for youngsters with autistic spectrum disorders in mainstream schools: what parents say — and what parents want

Relatively little research has focused on parental perceptions and experience of educational provision in mainstream settings for children and young people with autism. Much of that which has been undertaken (and certainly that which is most widely cited) has tended to rely on samples which may not be sufficiently representative. In the study reported here, Philip Whitaker, of the Children and Young People's Service in Northamptonshire sought the views of every parent or carer of a child with an autistic spectrum condition living within one English county. Almost half the parents of the 350 children attending mainstream schools responded to a questionnaire exploring their experiences, views, attitudes and levels of satisfaction. The analysis looks at the differences and similarities between the experiences and views of the 'satisfied' and 'dissatisfied' groups of parents.
Overall, 61% of respondents reported themselves satisfied with the provision being made for their children. The extent to which parents felt that school staff understood (and empathised) with their children's difficulties, and the perceived flexibility of the schools' responses to the children's needs were the factors which most sharply differentiated the two groups of parents. The extent and quality of reciprocal communication between home and school also seemed strongly associated with levels of satisfaction. The two groups of parents shared many concerns, with the schools' role in promoting social development and social relationships emerging as a high priority. Philip Whitaker discusses the implications of these findings for schools and for the development of local authority provision founded in mainstreaming.     

Towards an indigenous African educational discourse: a philosophical reflection

The liberation of Africa and its peoples from centuries of racially discriminatory colonial rule and domination has far reaching implications for educational thought and practice. The transformation of educational discourse in Africa requires a philosophical framework that respects diversity, acknowledges lived experience and challenges the hegemony of Western forms of universal knowledge. In this article, the author argues that indigenous knowledge, as a system of African knowledge, can provide a useful philosophical framework for the construction of empowering knowledge that will enable communities in Africa to participate in their own educational development.
