Projective Drawings in a Cerebellar Disorder Due to Chicken Pox Encephalitis

Projective drawings may be more sensitive to cerebellar disorders than the Rorschach or the geometric designs of the Bender. Drawings of a nine-year-old whose “bad case of chicken pox” was later diagnosed as varicella encephalitis are presented, with suggestions as to why this sensitivity may occur.     

The Cascade Neural Network Model and a Speed-Accuracy Trade-Off of Arm Movement

We propose a hybrid neural network model of aimed arm movements that consists of a feedforward controller and a postural controller. The cascade neural network of Kawato, Maeda, Uno, and Suzuki (1990) was employed as a computational implementation of the feedforward controller. This network computes feedforward motor commands based on a minimum torque-change criterion. If the weighting parameter of the smoothness criterion is fixed and the number of relaxation iterations is rather small, the cascade model cannot calculate the exact torque, and the hand does not reach the desired target by using the feedforward control alone. Thus, one observes an error between the final position and the desired target location. By using a fixed weighting parameter value and a limited iteration number to simulate target-directed arm movements, we found that the cascade model generated a planning time–accuracy trade-off, and a quasi–power-law type of speed–accuracy trade-off. The model provides a candidate neural mechanism to explain the stochastic variability of the time course of the feedforward motor command. Our approach also accounts for several invariant features of multijoint arm trajectories, such as roughly straight hand paths and bell-shaped speed profiles.     

Thick Ethical Concepts in the Philosophy and Literature of Iris Murdoch

Although thick ethical concepts have been neglected in Murdochian scholarship, this article argues that they were central to the thought of Iris Murdoch. In the first section, the article provides a sustained account of thick ethical concepts in Murdoch's philosophy, demonstrating how these concepts align with and illuminate familiar aspects of her philosophical essays. The first section also explores the ways in which Murdoch's alternative account of moral concepts was at the heart of her overall attack on the noncognitivism of her day. In the second section, the article provides a reading of The Black Prince and considers the ways that thick ethical concepts offer new insight into Murdoch's literary activity. It concludes by suggesting that studying Murdoch's philosophy and literature in light of thick ethical concepts reveals a deep unity between her two intellectual projects.     

Reasons for Randomness: A Solution to the Axiological Problem for Theists

Abstract

In this paper we bring to light several ways randomness—i.e., undetermined and unintended events—may contribute to our understanding of God's providence and personality. We begin by making clearer a certain problem that randomness has been thought to pose to theism. We then discuss recent criticisms of certain contemporary solutions to this problem that emphasize the value of an autonomous creation. From there, we propose a fresh way of understanding the value of a semi-autonomous creation that does not succumb to these recent critiques. Our end goal is to explore new reasons God might have to value randomness. In particular, we highlight two plausible, interrelated candidate values: (1) There are certain aesthetic properties that a partially random, self-forming creation enjoys; and (2) Such a creation grants God and creatures certain pleasures, such as wonder, anticipation, curiosity, surprise, and appreciation. In articulating our version of the autonomy defense, we position it within two opposing accounts of divine providence, specifically open theism and simple foreknowledge.     

Older is wiser? It depends who you ask… and how you ask

Interacting with older adults can trigger a number of stereotypes. Negative stereotypes tend to dominate, but a persistent positive perception of aging in the popular psyche is that age brings wisdom. Despite this common belief, previous research suggests that the relationship between age and wisdom is weak and inconsistent. We propose that this is due to opposing perceptions of aging – gains in life experience and socioemotional skills, counteracted by declines in cognitive skill – that also vary with characteristics of the perceiver and the context. We investigated these paradoxical perceptions of aging by asking younger (aged 20–40) and older (aged 60–80) adult judges to rate adult speakers (aged 30–89) on the basis of their responses to three narrative prompts. Several aspects of wisdom were judged, including those related to cognitive skills, and those related to socioemotional aspects of wisdom. We examined the impact on ratings of speaker and rater characteristics, as well as the interaction of these characteristics with the dimension being rated. Findings showed that the wisdom ratings were higher for speakers with better verbal fluency, and that the relationship between age and perceived wisdom was moderated by the speaker’s gender. Consistent with prior work, speaker age (relative to rater’s age) had a negative effect on cognitive aspects of wisdom, but a positive effect on socio-affective aspects of wisdom. Implications for understanding age-related stereotypes and conceptions of wisdom are discussed.     

Intrapersonal curiosity: Inquisitiveness about the inner self

Intrapersonal Curiosity (InC) involves inquisitively introspecting to better understand one’s inner self. A pool of 39 face-valid InC items was administered to 1005 participants, along with other curiosity, personality, self-awareness, self-regulation, and psychological well-being scales. Three InC factors with good model fit were identified, from which four-item (α ≥ .89) subscales were developed: “Understanding one’s Emotions and Motives,” “Reflecting On one’s Past,” and “Exploring one’s Identity and Purpose.” InC correlated positively with other measures of curiosity, evidencing convergence; weak correlations to conceptually unrelated constructs demonstrated divergence. Higher InC scores corresponded to perceptions of having less available self-knowledge, heightened sensitivity to others’ expressions, a greater tendency to privately introspect, increased distress, and more concern about how to best cope with worry over self-relevant threats.     

A RANDOMNESS‐BASED THEODICY FOR EVOLUTIONARY EVILS

We develop and knit together several theodicies in order to find a more complete picture of why certain forms of (nonhuman) animal suffering might be permitted by a perfect being. We focus on an especially potent form of the problem of evil, which arises from considering why a perfectly good, wise, and powerful God might use evolutionary mechanisms that predictably result in so much animal suffering and loss of life. There are many existing theodicies on the market, and although they offer helpful resources, we combine and further develop several proposals to produce a composite theodicy that avoids certain shortcomings of the individual theodicies. An important element of our project is locating a role for randomness in cosmic and biological evolution. In particular, we show how randomness might enhance or enable certain goods, including everlasting goods, at the risk of temporary evils.
