Pylyshyn could have strengthened his case by avoiding side issues and by taking a sterner, firmer line on the unresolved (and perhaps unresolvable) problems plaguing the sensitivity (d') measure of top-down, cognitive effects, as well as the general (nearly utter!) lack of convincing evidence provided by proponents of the cognitive penetrability of visual perception.

Chow pays lip service (but not much more!) to Type I errors and thus opts for a hard (all-or-none) .05 level of significance (Superego of Neyman/Pearson theory; Gigerenzer 1993). Most working scientists disregard Type I errors and thus utilize a soft .05 level (Ego of Fisher; Gigerenzer 1993), which lets them report gradations of significance (e.g., p.

For the first time, David Katz's classic monograph _The World of Touch_ has been translated into English. Regarded as one of the premiere experimental psychologists, Katz vigorously opposed the atomism and "tachistoscopic" mentality typical of the sensory psychology of his day. In _The World of Touch_, Katz sought to dispel the invidious distinction between the supposedly higher and lower senses. To help touch regain its original prominence in the field, Katz demonstrated, through very simple, yet creative experiments, how fascinating the (...) abilities of touch are, and how valuable the tactual stimulus can be in specifying objects, surfaces, substances, and events. In addition, Katz emphasized the importance of higher-order invariants in the perception of objects, and the holistic quality of perception in time as well as space. (shrink)

This comprehensive anthology of Bertrand Russell's writings brings together his definitive essays from the period 1903 to 1959. It covers the most fertile and the most lasting work on every significant area he published in.

We advocate for an integrative long-term perspective on time, noting that culture changes on timescales amenable to behavioral genetic study with appropriate design and modeling extensions. We note the need for replications of behavioral genetic studies to examine model invariance across long-term timescales, which would afford examination of specified as well as unspecified cultural moderators of behavioral genetic effects.

Essays on the relationship between perceptual experience and scientific thought--an introduction to the phenomenology of science.

This collection of new essays by eleven distinguished environmental philosophers addresses two main questions: first, whether environmental philosophy and ethics should be seen as a form of applied philosophy or as something else, perhaps best called practical philosophy; and second, how environmental philosophy is practiced in human life, especially in the lives of academics.

Originally published in French under the title La Logique de Husserl: Étude sur Logique Formelle et logique transcendentale.

Paul Ricoeur was one of the foremost interpreters and translators of Edmund Husserl's philosophy. These nine essays present Ricoeur's interpretation of the most important of Husserl's writings, with emphasis on his philosophy of consciousness rather than his work in logic. In Ricoeur's philosophy, phenomenology and existentialism came of age and these essays provide an introduction to the Husserlian elements which most heavily influenced his own philosophical position.

Compared to our understanding of positive prediction error signals occurring due to unexpected reward outcomes, less is known about the neural circuitry in humans that drives negative prediction errors during omission of expected rewards. While classical learning theories such as Rescorla–Wagner or temporal difference learning suggest that both types of prediction errors result from a simple subtraction, there has been recent evidence suggesting that different brain regions provide input to dopamine neurons which contributes to specific components of this prediction error (...) computation. Here, we focus on the brain regions responding to negative prediction error signals, which has been well-established in animal studies to involve a distinct pathway through the lateral habenula. We examine the activity of this pathway in humans, using a conditioned inhibition paradigm with high-resolution functional MRI. First, participants learned to associate a sensory stimulus with reward delivery. Then, reward delivery was omitted whenever this stimulus was presented simultaneously with a different sensory stimulus, the conditioned inhibitor. Both reward presentation and the reward-predictive cue activated midbrain dopamine regions, insula and orbitofrontal cortex. While we found significant activity at an uncorrected threshold for the CI in the habenula, consistent with our predictions, it did not survive correction for multiple comparisons and awaits further replication. Additionally, the pallidum and putamen regions of the basal ganglia showed modulations of activity for the inhibitor that did not survive the corrected threshold. (shrink)
