Having reasons

What is it to have a reason? According to one common idea, the Factoring Account, you have a reason to do A when there is a reason for you to do A which you have—which is somehow in your possession or grasp. In this paper, I argue that this common idea is false. But though my arguments are based on the practical case, the implications of this are likely to be greatest in epistemology: for the pitfalls we fall into when trying to defend the Factoring Account reflect very well the major developments in empiricist epistemology during the 20th century. I conjecture that this is because epistemologists have been—wrongly—wedded to the Factoring Account about evidence, which I conjecture is a certain kind of reason to believe.     

The Developmental Lexicon Project: A behavioral database to investigate visual word recognition across the lifespan

With the Developmental Lexicon Project (DeveL), we present a large-scale study that was conducted to collect data on visual word recognition in German across the lifespan. A total of 800 children from Grades 1 to 6, as well as two groups of younger and older adults, participated in the study and completed a lexical decision and a naming task. We provide a database for 1,152 German words, comprising behavioral data from seven different stages of reading development, along with sublexical and lexical characteristics for all stimuli. The present article describes our motivation for this project, explains the methods we used to collect the data, and reports analyses on the reliability of our results. In addition, we explored developmental changes in three marker effects in psycholinguistic research: word length, word frequency, and orthographic similarity. The database is available online.     

Reasons and Agent-neutrality

This paper considers the connection between the three-place relation, R is a reason for X to do A and the two-place relation, R is a reason to do A. I consider three views on which the former is to be analyzed in terms of the latter. I argue that these views are widely held, and explain the role that they play in motivating interesting substantive ethical theories. But I reject them in favor of a more obvious analysis, which goes the other way around.     

Inferential procedures for correlation coefficients corrected for attenuation

A model and computational procedure based on classical test score theory are presented for determination of a correlation coefficient corrected for attenuation due to unreliability. Next, variance-covariance expressions for the sample estimates defined earlier are derived, based on application of the delta method. Results of a Monte Carlo study are presented in which the adequacy of the derived expressions was assessed for a large number of data forms and potential hypotheses encountered in the behavioral sciences. It is shown that, based on the proposed procedures, confidence intervals for single coefficients are reasonably precise. Two-sample hypothesis tests, for both independent and dependent samples, are also accurate. However, for hypothesis tests involving a larger number of coefficients than two—both independent and dependent—the proposed procedures require largens for adequate precision. Results of a preliminary power analysis reveal no serious loss in efficiency resulting from correction for attenuation. Implications for practice are discussed.Support for the research reported in this article was provided by the Natural Sciences and Engineering Research Council of Canada.

Separate brain potential characteristics in children with reading disability and attention deficit disorder: color and letter relevance effects

This experiment was on event-related potential (ERP) indicants of the selective neural processing of black vs. white and letter vs. nonletter stimuli in boys (8-12 years of age) with and without a reading disability (RD) and/or attentional deficit disorder (ADD). Selective neural processing was measured by the increase or difference in ERP amplitude in response to stimuli that were relevant as compared to irrelevant to the color or letter attention task. The 52 children that participated in the study constituted four groups: 25 normal reading children (17 without ADD and 8 with ADD), and 27 RD children (11 without ADD and 16 with ADD). ERPs were recorded over the left and right occipital, central, and frontal regions. Selective neural processing due to stimulus relevance was reduced in boys with RD as compared to normal readers. This reduced selectivity was indicated by a predominantly symmetrical reduction in the magnitude of a positive difference potential over the central regions, between 300 and 360 msec, and then by a left greater than right hemisphere reduction in the magnitude of a positive difference potential over the occipital regions, at about 400 msec. Task relevance increased the within-subject and condition variability of this occipital positive component and this effect was greater for boys without than with RD, particularly over the left hemisphere. Selective neural processing due to stimulus relevance was greater in boys with ADD as compared to those without ADD. This was indicated by an increase in the magnitude of a positive difference potential between 320 and 400 msec over the central and frontal regions and a slow, late, negative difference potential between 600 and 800 msec over the central and occipital regions. These ADD effects tended to be greater over the right than left hemisphere. The unique polarity, scalp distribution, and time course of the effects of RD as compared to ADD on ERPs to relevant stimuli clearly indicated these two disorders, in part, involve different underlying brain deficits.     

The Effects of Delayed Report and Motive for Reporting on Perceptions of Sexual Harassment

We examined whether the timing of the report and the victim's apparent motive for reporting influences women's and men's perceptions of sexual harassment. Undergraduates (153 women, 149 men) listened to 1 of 6 versions of audiotaped testimony of the victim and defendant. The report was filed either immediately or 18 months later, and motive either was presented as altruistic, retaliatory, or was not specified. Participants chose a verdict, rated the defendant's guilt, and rated the defendant and victim on several dimensions. Higher guilt ratings, more positive evaluations of the victim, and more negative evaluations of the defendant were associated with immediate reporting and an altruistic motive, although women weighed these factors more heavily than did men.     

Inter-Parent Agreement on the Syndrome Scales of the Child Behavior Checklist (CBCL): Correspondence and Discrepancies

Using multiple informants from a clinical setting, potential associations between inter-parental agreement and age, gender, and child diagnosis were explored in the current study. Archival data from psychological evaluations conducted on 174 children ages 5–18 through a hospital-affiliated outpatient psychology clinic were analyzed, focusing on mothers’ and fathers’ scores on the syndrome and index scales of the Child Behavior Checklist (CBCL). Although inter-parent correspondence levels on each of the subscales were found to be moderately high (averaging r = .50), significant discrepancies between the severity levels of parent reports were found on nine of 11 subscales, with mothers’ ratings consistently being slightly higher. Data from this clinical sample suggest that although single-informant ratings of child behavior may be generally representative of reports from both parents on many of the CBCL narrow-band scales, age, gender, and child diagnosis were related to several patterns of agreement on specific syndrome scales. Therefore, it is important to include fathers, because they provide a unique perspective on social problems, delinquency, and attention problems, in particular. Both correspondence and discrepancies between parent reports of specific child problems can provide valuable clinical information that is useful for child assessment and treatment.
