Linking patterns of infant eye movements to a neural network model of the ventral stream using representational similarity analysis

Little is known about the development of higher-level areas of visual cortex during infancy, and even less is known about how the development of visually guided behavior is related to the different levels of the cortical processing hierarchy. As a first step toward filling these gaps, we used representational similarity analysis (RSA) to assess links between gaze patterns and a neural network model that captures key properties of the ventral visual processing stream. We recorded the eye movements of 4- to 12-month-old infants (N = 54) as they viewed photographs of scenes. For each infant, we calculated the similarity of the gaze patterns for each pair of photographs. We also analyzed the images using a convolutional neural network model in which the successive layers correspond approximately to the sequence of areas along the ventral stream. For each layer of the network, we calculated the similarity of the activation patterns for each pair of photographs, which was then compared with the infant gaze data. We found that the network layers corresponding to lower-level areas of visual cortex accounted for gaze patterns better in younger infants than in older infants, whereas the network layers corresponding to higher-level areas of visual cortex accounted for gaze patterns better in older infants than in younger infants. Thus, between 4 and 12 months, gaze becomes increasingly controlled by more abstract, higher-level representations. These results also demonstrate the feasibility of using RSA to link infant gaze behavior to neural network models. A video abstract of this article can be viewed at https://youtu.be/K5mF2Rw98Is     

Adaptation of the Coping With Stress Course for Black Adolescents in Low-Income Communities: Examples of Surface Structure and Deep Structure Cultural Adaptations

Black adolescents in low-income communities are at increased risk of developing mental health problems due to the impact of cumulative poverty-related stressors and racial discrimination, yet Black youth have relatively low rates of mental health service utilization, resulting in significant unmet need. The Coping With Stress (CWS) Course is an evidence-based, cognitive behavioral intervention that has been shown to reduce the incidence of anxiety, mood, and conduct problems among predominantly White samples, as well as Asian and Latinx youth. In the past 25 years since the CWS Course was introduced, Black adolescents have either been severely underrepresented or conspicuously absent from program evaluation research on the CWS Course, with few exceptions. The purpose of this article is threefold: (1) to justify the need for cultural adaptations to the CWS Course for Black adolescents from low-income communities, (2) to describe the scientific basis for the specific surface structure and deep structure modifications made to the culturally adapted version of the CWS Course, known as Resilient In spite of Stressful Events or RISE, and (3) to illustrate the deep structure adaptations with a vignette drawn from implementation of the RISE program with Black adolescents in a low-income, urban community.

Prenatal auditory experience and its sequelae

Towards the end of the second trimester of gestation, a human fetus is able to register environmental sounds. This in utero auditory experience is characterized by comprising strongly low-pass-filtered versions of sounds from the external world. Here, we present computational tests of the hypothesis that this early exposure to severely degraded auditory inputs serves an adaptive purpose—it may induce the neural development of extended temporal integration. Such integration can facilitate the detection of information carried by low-frequency variations in the auditory signal, including emotional or other prosodic content. To test this prediction, we characterized the impact of several training regimens, biomimetic and otherwise, on a computational model system trained and tested on the task of emotion recognition. We find that training with an auditory trajectory recapitulating that of a neurotypical infant in the pre-to-postnatal period results in temporally extended receptive field structures and yields the best subsequent accuracy and generalization performance on the task of emotion recognition. This strongly suggests that the progression from low-pass-filtered to full-frequency inputs is likely to be an adaptive feature of our development, conferring significant benefits to later auditory processing abilities relying on temporally extended analyses. Additionally, this finding can help explain some of the auditory impairments associated with preterm births, suggests guidelines for the design of auditory environments in neonatal care units, and points to enhanced training procedures for computational models.     

Between the Christ of Deep Incarnation and The African Jesus of Tinyiko Maluleke: An Improvised Dialogue

All differences considered, the Christ of deep incarnation and the African Jesus of Tinyiko Maluleke share at least one fundamental dimension: they both stand out as signs of God's radical embodiment in the world of creation/of African culture(s). Put crudely, while the deep incarnation theologians extend Jesus’ body into social and cosmic bodies, Maluleke locates Jesus’ body in the bodies of his fellow Africans. This study first identifies major convergences and tensions between these two christological perspectives and, second, posits that the scandal of reciprocity, seen as a characteristic feature of African christologies, can be translated into a twofold guiding principle for approaching and assessing African Christianity theologically.     

THE ENTANGLED TRINITY,QUANTUM BIOLOGY,AND DEEP INCARNATION

By utilizing the concept of quantum decoherence, augmented by the novel theory of quantum Darwinism, to understand the transition from the quantum to the classical worlds, the scaling up of the concept of quantum entanglement2018 to the biological level offers a fascinating metaphor for the presence of the creative spirit in nature and the “flesh” of Incarnation. This in turn provides helpful theological metaphors for articulating divine presence at the level of life in theistic evolution, partially addressing the issue of evolutionary theodicy by supporting the concept of deep Incarnation. The point of understanding the Incarnation as deeply entangled enfleshment is that it brings the suffering of creation into the life of the Redeemer as well as the Creator, facilitating redemption and hope through the divine life.     

Arrested Development: On Hegel,Heidegger and Derrida

ABSTRACT

Although both Heidegger and Derrida criticize Hegel as the archetype and historical culmination of the metaphysics of presence, Hegel’s dialectics also serves as a model for their critical destruction or deconstruction of metaphysics. Through an analysis of the notions of ‘arrest’ and ‘halt’ in Derrida and Hegel, this paper will show how both Heidegger and Derrida take up elements of Hegel’s theory of the development of consciousness, which is characterized both by an ‘unhalting forward motion’ but also by delay, interruption and inertia. This paper will develop the strange parallel between Derrida’s notion of l’arrêt and the halting movement of spirit in Hegel. It will show that Hegel’s ‘rhythm of the concept’ is not so distant from the ‘arrhythmia’ Derrida finds in the notion of l’arrêt. It will thus show how time, history and spirit are linked in a self-deconstructive manner in this unstable point of the arrest/halt.     

The self in deep ecology: A response to Watson

ABSTRACT

Richard Watson maintains that deep ecology suffers from an internal contradiction and should therefore be rejected. Watson contends that deep ecology claims to be non-anthropocentric while at the same time is committed to setting humans apart from nature, which is inherently anthropocentric. I argue that Watson’s objection arises out of a fundamental misunderstanding of how deep ecologist’s conceive of the ‘Self.’ Drawing on resources from Buddhism, I offer an understanding of the ‘Self’ that is fully consistent with deep ecology, and does not lead to the anthropocentric contradiction that Watson identifies. The paper will proceed as follows: First, I articulate Watson’s objection, and briefly discuss the traditional deep ecology position. Next, I turn to a discussion of the ‘Self’ and show that there are conceptions of human nature that are not separate from ‘Nature.’ It will thus be shown that deep ecology is not inconsistent and need not be rejected.
