The effect of word frequency, word predictability, and font difficulty on the eye movements of young and older readers

Young adult and older readers' eye movements were recorded as they read sentences containing target words that varied in frequency or predictability. In addition, half of the sentences were printed in a font that was easy to read (Times New Roman) and the other half were printed in a font that was more difficult to read (Old English). Word frequency, word predictability, and font difficulty effects were apparent in the eye movement data of both groups of readers. In the fixation time data, the pattern of results was the same, but the older readers had larger frequency and predictability effects than the younger readers. The older readers skipped words more often than the younger readers (as indicated by their skipping rate on selected target words), but they made more regressions back to the target words and more regressions overall. The E-Z Reader model was used as a platform to evaluate the results, and simulations using the model suggest that lexical processing is slowed in older readers and that, possibly as a result of this, they adopt a more risky reading strategy.     

Distinctions Between Hostile and Nonhostile Forms of Perceived Criticism From Others

Criticism and hostility from others are related to fluctuations in symptom severity across many disorders, including depression and anxiety. Objective coding systems typically allow for distinctions between criticism and hostility, but the primary self-report measure of perceptions of criticism (the Perceived Criticism Measure) contains no such distinction. This report presents results from two samples regarding the assessment of specific perceptions of hostile and nonhostile criticism. In addition to these specific perceptions, we assessed relationship satisfaction, perceptions of overall criticism, and symptoms of depression and anxiety. Perceptions of hostile criticism were similar to ratings of overall criticism, as indicated by a positive correlation between these two and similar correlations with related variables. In contrast, perceptions of nonhostile criticism demonstrated more complex patterns of associations, showing a positive correlation with relationship satisfaction, a negative correlation with perceptions of hostile criticism, and a positive association with general perceptions of criticism only in the context of low depressive symptoms (as depressive symptoms increased, this association became significantly weaker). These results suggest that respondents do distinguish between perceptions of hostile and nonhostile criticism, and these perceptions are not simply different points on the same continuum. Moreover, they suggest that individuals with higher levels of depression may be less likely to incorporate nonhostile criticism into their overall perceptions of criticism from others.     

REJOINDER: Picasso's Guernica Creativity as a Darwinian Process: Definitions,Clarifications, Misconceptions,and Applications

The author responds to four commentaries on Simonton (this issue). The response deals with two sets of issues. First are criticisms of the Darwinian theory of creativity, especially as applied to Picasso's sketches for the Guernica. These criticisms range from the presumed role of associative processes to the essential nature of any Darwinian model. The second set of issues pertains to diverse methodological objections with respect to measurement and data analysis. The author responds to each and every point. The author concludes not only that Picasso's creative process is best described as Darwinian, but also that the Darwinian theory of creativity has been notably strengthened by the current exchange.     

Opening the Closed Mind: The Effect of Exposure to Literature on the Need for Closure

The need for cognitive closure has been found to be associated with a variety of suboptimal information processing strategies, leading to decreased creativity and rationality. This experiment tested the hypothesis that exposure to fictional short stories, as compared with exposure to nonfictional essays, will reduce need for cognitive closure. One hundred participants were assigned to read either an essay or a short story (out of a set of 8 essays and 8 short stories matched for length, reading difficulty, and interest). After reading, their need for cognitive closure was assessed. As hypothesized, when compared to participants in the essay condition, participants in the short story condition experienced a significant decrease in self-reported need for cognitive closure. The effect was particularly strong for participants who were habitual readers (of either fiction or non-fiction). These findings suggest that reading fictional literature could lead to better procedures of processing information generally, including those of creativity.     

The Hierarchical Personality Structure of Aspiring Creative Writers

Empirical studies of personality traits in creative writers have demonstrated mixed findings, perhaps due to issues of sampling, measurement, and the reporting of statistical information. The goal of this study is to quantify the personality structure of aspiring creative writers according to a modern hierarchal model of trait personality. A sample of aspiring writers (n = 93) and nonwriters (n = 114) completed the Big Five inventory. Correlations with personality were carried out at three levels: the Big Five traits, the two higher-order factors (stability and plasticity), and the more detailed facet-level. Consistent with past research, creative writers scored higher on trait openness. Extending past work, the hierarchical analysis also revealed novel correlates for the higher-order meta-traits (stability and plasticity) and some of the lower-order facets (aesthetics, ideas, activity, assertiveness, and depression). Individuals with higher scores on agreeableness, stability, and assertiveness were less likely to be aspiring writers. The likelihood of being a writer also decreased with age. Taken together, these findings indicate that aspiring creative writers differ from nonwriters in trait personality, with differences emerging at all levels of the personality hierarchy.     

Aid and bias

Over the last few decades, psychologists have amassed a great deal of evidence that our thinking is strongly influenced by a number of biases. This research appears to have important implications for moral methodology. It seems likely that these biases affect our thinking about moral issues, and a fuller awareness of them might help us to find ways to counteract their influence, and so to improve our moral thinking. And yet there is little or no reference to such biases in the philosophical literature on many pressing, substantive moral questions. In this paper, I make a start on repairing this omission in relation to one such question, the 'Aid Question', which concerns how much, if anything, we are morally required to give to aid agencies. I begin by sketching a number of biases that seem particularly likely to affect our thinking about that question. I then go on to review the psychological research on 'debiasing' - that is, on attempts to counteract the influence of such biases. And finally I discuss and illustrate certain strategies for counteracting the influence of the biases in question on our thinking about the Aid Question.     

Specificity of Task Constraints and Effects of Visual Demonstrations and Verbal Instructions in Directing Learners' Search During Skill Acquisition

In the present study, the efficacy of visual demonstrations and verbal instructions as instructional constraints on the acquisition of movement coordination was investigated. Fifteen participants performed an aiming task on 100 acquisition and 20 retention trials, under 1 of 3 conditions: a modeling group (MG), a verbally directed group (VDG), and a control group (CG). The MG observed a model intermittently throughout acquisition, whereas the VDG was verbally instructed to use the model's movement pattern. Participants in the CG received neither form of instruction. Kinematic analysis revealed that compared with verbal instructions or no instructions, visual demonstrations significantly improved participants' approximation of the model's coordination pattern. No differences were found in movement outcomes. Coordination data supported the visual perception perspective on observational learning, whereas outcome data suggested that the modeling effect is mainly a function of task constraints, that is, the novelty of a movement pattern.     

Age and Cognitive Stress Influences Motor Skill Acquisition,Consolidation, and Dual-Task Effect in Humans

This study examined motor skill learning using a weight-bearing and cognitive-motor dual-task that incorporated unexpected perturbations and measurements of cognitive function. Forty young and 24 older adults performed a single-limb weight bearing task with novel speed, resistance, and cognitive dual task conditions to assess motor skill acquisition, retention and transfer. Subjects performed a cognitive dual task: summing letters in one color/orientation (simple) or two colors/orientations (complex). Increased cognitive load diminished the rate of skill acquisition, decreased transfer to new conditions, and increased error rate during an unexpected perturbation; however, young adults had a dual-task benefit from cognitive load. Executive function predicted 80% of the variability in dual-task performance. Although initial learning of a weight-bearing cognitive-motor dual-task was poor, longer term goals of improved dual-task effect and retention emerged.     

Contingent Reinforcement Effects on Movement Responses of Prison Inmates to the Holtzman Inkblot Technique

Prison inmates were administered the Holtzman Inkblot Technique (HIT) under conditions of either verbal or nonverbal reinforcement of movement responses. Overall, there were no differences among the verbal, nonverbal, and control groups. Inmates charged with violent crimes were found to give the fewest movement responses. With crime category controlled, more movement responses were given under nonverbal conditions. There were no sex differences for movement responses but testing time increased significantly when administered by the female examiner.
