Food-deprivation-induced behavioral arousal: mediation by hypothalamus and amygdala.

Electrolytic lesions of the basomedial hypothalamus eliminated food-deprivation-induced stabilimeter activity in rats that were prevented from becoming obese. Knife cuts lateral to the basomedial area (separating the medial and lateral hypothalamus) potentiated this activity, as did transections posterior to the basomedial region. Anterior transections (between anterior and medial hypothalamus), however, eliminated the effect. Lesions of the stria terminalis and amygdala likewise abolished deprivation-induced locomotor activity, but elevated ab-lib activity to a level comparable with that after deprivation in intact animals. Animals with combined basomedial-stria terminalis lesions behaved like animals with basomedial lesions. These results suggest that food-deprivation-induced locomotor activity in stabilimeter cages is due to a disinhibition of the basomedial hypothalamus by the amygdala via the stria terminalis.     

Perceptual asymmetries are preserved in memory for highly familiar faces of self and friend

We investigated the effect of familiarity on people's perception of facial likeness by asking participants to choose which of two mirror-symmetric chimeric images (made from the left or right half of a photograph of a face) looked more like an original image. In separate trials the participants made this judgment for their own face and for the face of a close friend; half of them matched to a true image of the original and half matched to a mirror image of the original. In the case of matching to a friend's face presented in the familiar orientation, over 80% of participants chose the left-left composite to be a better likeness to the original, whereas only 62% showed the same left-side bias when matching to a mirror image. The difference is significant, and the result contrasts markedly with a second experiment where participants who were unfamiliar with the faces showed comparable left-side biases when matching to true or mirror reversed images. The result suggests that perceptual asymmetries are retained in our long-term memory for highly familiar faces. While matching to images of self also showed an effect of familiarity, the data in this condition show less evidence of perceptual asymmetry and are discussed in relation to recent research on the representation of one's own face.     

Politics,lack of career progress,and work/home conflict: Stress and strain for working women

This study examines the stress experienced by working women in terms of politics, lack of career progress, and work/home conflicts, the symptoms of distress and satisfaction associated with these stressors, and the organizational resources available for managing these demands. Subjects were 195 female personnel professionals. A different pattern of results emerged for politics and lack of career progress in contrast to work/home conflicts. Specifically, politics and lack of career progress were associated with greater strain symptoms and reduced satisfaction, and organizational resources were associated with lower levels of these stressors. Work/home conflicts were associated with greater strain symptoms, but were unrelated to satisfaction and organizational resources. This suggests that organizations identify the most effective targets of their resources to achieve beneficial results.     

Counselling Older Adults Living in Residential Aged Care Settings: Four Illustrative Case Studies

The role of psychologists and other mental health professionals in long‐term care settings is undefined in Australia. Graduate psychology students receive little training in clinical geropsychology, and residential aged care providers do not routinely employ psychologists within such settings. Further, despite high rates of depression, neurocognitive problems, and other mental health problems, residents are rarely referred for evidence‐based psychological treatment. This article presents four case studies showing how psychology services may be employed in such settings within the context of a postgraduate psychology placement programme. These case studies emphasise the importance of engagement, the use of flexible and individualised treatment approaches, and the involvement of family and professional carers in the provision of psychological services. Psychology services in residential settings can have a positive impact on the care of older adults and their families.     

Constructivism and the Limits of Reason: Revisiting the Kantian Problematic

The main focus of this paper ison ways in which Kantian philosophy can informproponents and opponents of constructivismalike. Kant was primarily concerned withreconciling natural and moral law. His approachto this general problematic was to limit andseparate what we can know about things(phenomena) from things as they are inthemselves (noumena), and to identify moralagency with the latter. Revisiting the Kantianproblematic helps to address and resolve longstanding epistemological concerns regardingconstructivism as an educational philosophy inrelation to issues of objectivity andsubjectivity, the limits of theoretical andpractical reason, and the relation betweenhuman experience and the world. It also servesto address ethical concerns regardingliberation from limited self-interests andcontexts conditioned by localised beliefs andinclinations. In light of revisiting theKantian problematic, both Glasersfeld's radicalview of constructivism and Jardine's socialcritique of constructivism are found wanting.Beyond constructivism, Kant's distinctionbetween phenomena and noumena and the limits ofreason that follow from it are brieflyconsidered in terms of Merleau-Ponty's noveldouble-embodied notion of flesh as anontological primitive – as a matter of beingboth in, and of, the world – with an aim tomore intimate connections between epistemologyand ethics.     

Studying Technology and Ecclesiology in Online Multi-Site Worship

This study brings together research approaches from media studies and practical theology in order to study and understand the relationship between online technological features of multi-site worship and the larger offline worshipping community to which it is connected. From the perspective of media studies we reflect on how new media technologies and cultures are allowed to shape online worship spaces and how larger institutional traditions and structures are allowed to shape technologically mediated church events. From the perspective of practical theology we use the notion of inculturation as a lens for a better understanding of the specific ways in which Christian worship practices adapt, change, and respond to the new cultural setting which emerges from the online worship context. Together, these approaches illuminate the interplay between digital technology and ecclesiological tradition in shaping multi-site church worship practices.     

Variations in the Gender-Stereotyped Content of Children's Television Cartoons Across Genres

This study examined the gender-stereotyped content of children's TV network cartoons across 4 genres: traditional adventure (e.g., "Spiderman"), nontraditional adventure (e.g., "Reboot"), educational/family (e.g., "Magic School Bus"), and comedy ("Animaniacs"). Acting negatively, showing physical aggression, and being a victim were significantly less likely in the educational/family genre cartoons than any of the other three genres. Demonstrating romantic behavior was significantly more likely in the traditional adventure and the comedy genres than the other genres. Male characters were represented in cartoons significantly more than were female characters, but only in the traditional adventure and the comedy genres. Male characters were more likely than were female characters to use physical aggression, but only in the traditional adventure genre. Behaviors that were relatively more likely among female characters across genres included showing fear, acting romantic, being polite, and acting supportive. Most of the significant differences were also associated with very large effect sizes.     

Effects of mixing and cueing simple addition and multiplication

Miller and Paredes (1990) found that both children's and adults' performance of simple addition and multiplication tested in mixed-operation blocks was slower and more susceptible to operation errors (e.g., 6 + 2=12 or 6×2=8) compared to pure-operation blocks; but mixed-operation costs were greater for addition than for multiplication. We pursued the source of these effects in adults (n=96) by examining effects of operation switching and cueing. We replicated the asymmetrical costs of mixing addition and multiplication and demonstrated that these owed, in part, to asymmetrical task switching costs. Operation foreknowledge (a visual cue appearing 2 s before the problem) moderated both mixing and switch costs. This suggests that an asymmetry between addition and multiplication in the utility of preparation contributed to asymmetric mixing costs. Miller and Paredes proposed that the asymmetric costs of mixing operations observed in adults echoed an asymmetry developed in childhood when multiplication is initially learned. This might be correct, but our results raise the possibility that the asymmetry reflects operation-specific costs and interference effects that arise during the experiment.
