Belief-content justification for cases of a priori justification: A neo-Haackian model

I differentiate justification of the subject (S-justification) from justification of the content of a belief (C-justification) and note the questions associated with truth conduciveness of justification. I employ Susan Haack’s analysis of empirical justification and show how, with certain adaptations, it can account for justification from non-experiential sources, if there are any. I give at least one example from mathematical visual thinking.     

Reading Without Words: Eye Movements in the Comprehension of Comic Strips

The study of attention in pictures is mostly limited to individual images. When we ‘read’ a visual narrative (e.g., a comic strip), the pictures have a coherent sequence, but it is not known how this affects attention. In two experiments, we eyetracked participants in order to investigate how disrupting the visual sequence of a comic strip would affect attention. Both when panels were presented one at a time (Experiment 1) and when a sequence was presented all together (Experiment 2), pictures were understood more quickly and with fewer fixations when in their original order. When order was randomised, the same pictures required more attention and additional ‘regressions’. Fixation distributions also differed when the narrative was intact, showing that context affects where we look. This reveals the role of top‐down structures when we attend to pictorial information, as well as providing a springboard for applied research into attention within image sequences.Copyright © 2016 John Wiley & Sons, Ltd.     

Eye Movements in Strategic Choice

In risky and other multiattribute choices, the process of choosing is well described by random walk or drift diffusion models in which evidence is accumulated over time to threshold. In strategic choices, level‐k and cognitive hierarchy models have been offered as accounts of the choice process, in which people simulate the choice processes of their opponents or partners. We recorded the eye movements in 2 × 2 symmetric games including dominance‐solvable games like prisoner's dilemma and asymmetric coordination games like stag hunt and hawk–dove. The evidence was most consistent with the accumulation of payoff differences over time: we found longer duration choices with more fixations when payoffs differences were more finely balanced, an emerging bias to gaze more at the payoffs for the action ultimately chosen, and that a simple count of transitions between payoffs—whether or not the comparison is strategically informative—was strongly associated with the final choice. The accumulator models do account for these strategic choice process measures, but the level‐k and cognitive hierarchy models do not. © 2015 The Authors.

Process Overlap Theory: A Unified Account of the General Factor of Intelligence

The most replicated result in the field of intelligence is the positive manifold, which refers to an all-positive pattern of correlations among diverse cognitive tests. The positive manifold is typically described by a general factor, or g. In turn, g is often identified as general intelligence, yet this explanation is contradicted by a number of results. Here we offer a new account of g: process overlap theory. According to the theory, cognitive tests tap domain-general executive processes, identified primarily in research on working memory, as well as more domain-specific processes. Executive processes are tapped in an overlapping manner across cognitive tests such that they are required more often than domain-specific ones. The theory provides an account of a number of findings on human intelligence. As well, it is formalized as a multidimensional item response model and as a structural model, and the neural mechanisms underlying the proposed overlapping processes are discussed.     

The Visual Guide to Morality: Vision as an Integrative Analogy for Moral Experience,Variability and Mechanism

Analogies help organize, communicate and reveal scientific phenomena. Vision may be the best analogy for understanding moral judgment. Although moral psychology has long noted similarities between seeing and judging, we systematically review the “morality is like vision” analogy through three elements: experience, variability and mechanism. Both vision and morality are experienced as automatic, durable and objective. However, despite feelings of objectivity, both vision and morality show substantial variability across biology, culture and situation. The paradox of objective experience and cultural subjectivity is best understood through constructionism, as both vision and morality involve the flexible combination of more basic ingredients. Specifically, both vision and morality involve a mechanism that demonstrates Gestalt, combination and coherence. The “morality is like vision” analogy not only provides intuitive organization and compelling communication for moral psychology but also speaks to debates in the field, such as intuition versus reason, pluralism versus universalism and modularity versus constructionism.     

Meaning above the head: combinatorial constraints on the visual vocabulary of comics

“Upfixes” are “visual morphemes” originating in comics where an element floats above a character’s head (ex. lightbulbs or gears). We posited that, similar to constructional lexical schemas in language, upfixes use an abstract schema stored in memory, which constrains upfixes to locations above the head and requires them to “agree” with their accompanying facial expressions. We asked participants to rate and interpret both conventional and unconventional upfixes that either matched or mismatched their facial expression (Experiment 1) and/or were placed either above or beside the head (Experiment 2). Interpretations and ratings of conventionality and face–upfix matching (Experiment 1) along with overall comprehensibility (Experiment 2) suggested that both constraints operated on upfix understanding. Because these constraints modulated both conventional and unconventional upfixes, these findings support that an abstract schema stored in long-term memory allows for generalisations beyond memorised individual items.     

‘A good odour to breathe?’ The effect of pleasant ambient odour on human visual vigilance

The present study examined the effect of an alerting and a relaxing odour on human visual vigilance. Three groups of undergraduates (N = 54) completed a sustained visual vigilance task which required them to respond whenever a target stimulus appeared on a computer monitor. One group completed the task in the presence of an alerting odour (peppermint), another did so in the presence of a relaxing odour (bergamot) and a third group completed the task in an unscented environment. A 2×3×2 (sex×odour×diurnal preference) MANOVA was performed in order to determine group differences in response times and number of correct detections. Participants in the bergamot condition detected fewer targets correctly within 1.25 seconds of the target appearing than did those in the peppermint or no‐odour groups. Exposure to bergamot was also associated with significantly fewer correct detections in the second than in the first half of the task, when compared with the other two conditions. The results suggest that sustained exposure to a relaxing odour can impair visual vigilance. Copyright © 2001 John Wiley & Sons, Ltd.     

Why do schools of thought fail? Neo-Freudianism as a case study in the sociology of knowledge

A full account of the social production of knowledge requires an understanding of how schools of thought fail, as well as succeed. This paper offers a sociology of knowledge analysis of the collapse of neo-Freudianism as a separate school of psychoanalysis and influential intellectual current. While the existing literature stresses personal conflicts between Karen Horney, Erich Fromm and Harry Stack Sullivan as a major cause of the failure of cultural psychoanalysis, my analysis highlights the sect-like nature of Freudian institutes, the professionalizing dynamics of American psychoanalysis, the contribution of the celebrity-dominated book market and culture, and the highly controversial nature of Erich Fromm's writings and intellectual activity. Neo-Freudianism is conceptualized as a hybrid system that is a combination of a literary phenomena, intellectual movement, faction of a sect, theoretical innovation and therapy. This analysis of hybrid intellectual systems raises larger sociology of knowledge questions about schools of thought and intellectual movements. © 1998 John Wiley & Sons, Inc.     

Repeated exposure to violent and nonviolent pornography: Likelihood of raping ratings and laboratory aggression against women

This study examined the relatively long-term effects of repeated exposure to violent and nonviolent pornography on male' laboratory aggression against women. Self-reported likelihood of raping was also assessed as an individual differences variable that might mediate susceptibility to the effects of pornography and to ascertain whether it predicted actual aggressive behavior. Subjects were randomly assigned to the sexually violent, sexually nonviolent, or control exposure conditions. Those assigned to the sexually violent or sexually nonviolent conditions were exposed over a four-week period to ten stimuli including feature-length films and written and pictorial depictions, whereas control subjects were not exposed to any stimuli. About a week following the end of the exposure phase, subjects participated in what they believed to be a totally unrelated experiment in which aggression was assessed within a Buss paradigm. Exposure to the violent or nonviolent pornographic stimuli was not found to affect laboratory aggression. These data are discussed in terms of a recent analysis of media effects emphasizing the temporary activation of ideas in audience' minds. Likelihood of raping ratings was found to predict laboratory aggression.
