Knowing when to hear aids what to hear

Temporal preparation often has been assumed to influence motor stages of information processing. Recent studies, however, challenge this notion and provide evidence for a facilitation of visual processing. The present study was designed to investigate whether perceptual processing in the auditory domain also benefits from temporal preparation. To this end, we employed a pitch discrimination task. In Experiment 1, discrimination performance was clearly improved when participants were temporally prepared. This finding was confirmed in Experiment 2, which ruled out possible influences of short-term memory. The results support the notion that temporal preparation enhances perceptual processing not only in the visual, but also in the auditory, modality.     

Biases in visual orienting to negative and positive scenes in dysphoria: An eye movement study

The study investigated biases for negative information in component processes of visual attention (initial shift vs. maintenance of gaze) in dysphoric and nondysphoric individuals. Eye movements were recorded while participants viewed a series of picture pairs depicting negative, positive, and neutral scenes (each pair presented for 3 s). Biases in initial orienting were assessed from the direction and latency of the initial shift in gaze, whereas biases in the maintenance of attention were assessed from the duration of gaze on the picture that was initially fixated. Results indicated that the dysphoric group showed a significantly greater bias to maintain gaze longer on negative pictures, relative to control pictures, compared with the nondysphoric group. There was no evidence of a dysphoria-related bias in initial shift of orienting to negative cues. Results are consistent with a depression-related bias that operates in the maintenance of attention on negative material.     

Newton versus Leibniz: intransparency versus inconsistency

In this paper I argue that inconsistencies in scientific theories may arise from the type of causality relation they—tacitly or explicitly—embody. All these seemingly different causality relations can be subsumed under a general strategy developed to defeat the paradoxes which inevitably occur in our experience of the real. With respect to this, scientific theories are just a subclass of the larger class of metaphysical theories, construed as theories that attempt to explain a (part of) the world consistently. All metaphysical theories share a common structural backbone specificially designed to defeat paradoxes, their often wildly diverging ontological claims notwithstanding. This common structure shapes the procedures which govern the invention of ideas in the context of such theories, by codifying some onto-logical a priori assumptions regarding the consistency of reality into its bare conceptual framework. Causality plays a key rôle here, because it implies conservation of identity, itself a far from simple notion. It imposes strong demands on the universalising power of the theories concerned. These demands are often met by the introduction of a metalevel which encompasses the notions of ‘system’ and ‘lawful behaviour’. In classical mechanics, the division between universal and particular leaves its traces in the separate treatment of cinematics and dynamics. The fundamental backbone’s specific gestalt thus functions as a theory’s individual signature and paves the way to a comparative historical approach towards their study. An important part of my paper therefore explores the strong connections between paradoxes as they appear and are dealt with in ancient philosophy and their re-appearance in early modern natural philosophy and science. This analysis is applied to the mechanical theories of Newton and Leibniz, with some surprising results.     

Poorer aerobic fitness relates to reduced integrity of multiple memory systems

Epidemiological investigations have revealed increases in the prevalence of sedentary behaviors in industrialized societies. However, the implications of those lifestyle choices and related cardiorespiratory fitness levels for memory function are not well-understood. To determine the extent to which cardiorespiratory fitness relates to the integrity of multiple memory systems, a cross-sectional sample of young adults were tested over the course of 3 days in areas related to implicit memory, working memory, long-term memory, and aerobic fitness. Findings revealed an association between aerobic fitness and memory function such that individuals with lower cardiorespiratory fitness exhibited poorer implicit memory performance and poorer long-term memory retention. These data indicate that cardiorespiratory fitness may be important for the optimal function of neural networks underlying these memory systems.     

A Developmental Psychopathology and Neurobiological Model of Borderline Personality Disorder in Adolescence

The antecedents and risk factors and for developing borderline personality disorder (BPD) are now well documented, but there is a paucity of developmental models to understand the key processes through which they impact on the development of BPD in adolescents. In this article, we present a developmental psychopathology model of BPD in adolescence and link the difficulties adolescents with BPD have with impulsivity and self regulation, with risk factors such as genetic vulnerability, parenting and trauma. We propose a number of psychological processes through which these risk factors undermine personal and interpersonal functioning, and makes it particularly difficult to engage with the challenges of adolescence. These key psychological processes undermine the integration of the self, with extreme unintegrated affects and extreme representations of self and others, undermining the capacity to mentalize. We then make links to possible neurobiological underpinnings of the disturbances in affect, Theory of Mind and interpersonal difficulties in adolescents with BPD.     

The Philosophy for Children Curriculum: Resisting ‘Teacher Proof’ Texts and the Formation of the Ideal Philosopher Child

The philosophy for children curriculum was specially written by Matthew Lipman and colleagues for the teaching of philosophy by non-philosophically educated teachers from foundation phase to further education colleges. In this article I argue that such a curriculum is neither a necessary, not a sufficient condition for the teaching of philosophical thinking. The philosophical knowledge and pedagogical tact of the teacher remains salient, in that the open-ended and unpredictable nature of philosophical enquiry demands of teachers to think in the moment and draw on their own knowledge and experience of academic philosophy. Providing specialist training or induction in the P4C curriculum cannot and should not replace undergraduate and postgraduate degrees in academic philosophy at universities. However, although for academic philosophers the use of the P4C curriculum could be beneficial, I will argue that its use poses the risk of wanting to form children into the ideal ‘abnormal’ child, the thinking child—the adult philosopher’s child positioned as such by the Lipman novels. The notion of narrativity is central in my argument. With the help of two picturebooks—The Three Pigs (2001) by David Weisner and Voices in the Park (1998) by Anthony Browne—I illustrate my claim that philosophy as ‘side-shadowing’ or meta-thinking can only be generated in the space ‘in between’ text, child and educator, thereby foregrounding a ‘pedagogy of exposure’ (Biesta 2011) rather than ‘teacher proof’ texts.
