Are children moral objectivists? Children's judgments about moral and response-dependent properties

Researchers working on children's moral understanding maintain that the child's capacity to distinguish morality from convention shows that children regard moral violations as objectively wrong (e.g. Nucci, L. (2001). Education in the moral domain. Cambridge: Cambridge University Press). However, one traditional way to cast the issue of objectivism is to focus not on conventionality, but on whether moral properties depend on our responses, as with properties like icky and fun. This paper argues that the moral/conventional task is inadequate for assessing whether children regard moral properties as response-dependent. Unfortunately, children's understanding of response-dependent properties has been neglected in recent research. Two experiments are reported showing that children are more likely to treat properties like fun and icky as response-dependent than moral properties like good and bad. Hence, this helps support the claim that children are moral objectivists.     

The Effect of Selective Serotonin Releasing Agents in the Chronic Mild Stress Model of Depression in Rats

Chronic exposure to mild unpredictable stress has been found to depress the consumption of, and preference for, highly palatable sucrose solution in rats. Stress-induced behavioral deficits may be maintained for a long time, however chronic administration of clinically effective antidepressants can restore normal behavior. This is the first report showing that Sprague-Dawley rats can be used in this model. A preference deficit in this strain of rats took at least 7 weeks to develop; about twice the time required when hooded Lister or Wistar rats are used in this model. Water consumption was not effected by chronic exposure to the mild stress regime and/or by chronic administration of the selective serotonin (5-HT) releasing agent MMAI (5-methoxy-6-methyl-2-aminoindan). The stress-induced deficit in sucrose intake was completely reversed by chronic treatment with MMAI (5 mg/kg, 2 x day) over 3 weeks in the two-bottle tests. In single-bottle tests, chronic treatment with the selective 5-HT releasers, MMAI (5 mg/kg, 2 x day) or MTA (p-methylthioamphetamine; 5 mg/kg, 2 x day), reversed the deficit in rewarded behavior (anhedonia) measured as a decrease in the consumption of 1% sucrose solution in the chronic mild stress model of depression in rats. With the experimental procedure employed, and at a dose of 10 mg/kg/day of 5-HT releasers, the magnitude and onset of this effect were greater than observed following similar administration of the selective 5-HT reuptake inhibitor (SSRI) sertraline (10 mg/kg/day), used as a standard anti-depressant drug.     

DEVELOPMENT OF MULTIPLE JOB PERFORMANCE MEASURES IN A REPRESENTATIVE SAMPLE OF JOBS

The goal of criterion development in Project A was to construct multiple measures of the major components of job performance such that the total performance domain for a representative sample of the population of entry-level enlisted positions in the U.S. Army was covered. These measures were to be used as criteria against which to validate both experimental and existing predictors of job performance. The initial model specified that performance is multidimensional within two major categories of dimensions designated as organization-wide and job specific. The development strategy involved describing the total domain of job content via extensive task analyses and critical incident analyses, generating the critical performance dimensions that constitute it, constructing measures for each dimension, and evaluating each measure using expert judgment and field test data. The specific measures developed consisted of rating scales, tests of job knowledge, hands-on job samples, and archival records. The major steps in the job analyses, content sampling, instrument construction, and instrument evaluation are described, and the final array of criterion measures is presented.     

Using HyperCard to administer a figural test on the Apple Macintosh

To date, applications of automated assessment techniques in personality testing have largely been limited to objective personality instruments with text stimuli; few assessment applications have involved graphic stimuli. Although projective personality instruments generally include ambiguous graphic or pictorial stimuli, computer applications with these procedures have been limited to automated scoring and interpretation, administration of sentence completion devices employing text stimuli, and the use of mechanical methods rather than computer graphics to display visual stimuli. In the present report, we describe a Macintosh HyperCard application for administering an objective personality test with visual stimuli, the Barron-Welsh Revised Art Scale of the Welsh Figure Preference Test. This test consists of a series of figural stimuli and a binary “like”/“dislike” response format, and it thus represents an administration procedure between standard objective self-report inventories involving text stimuli and a “true”/“false” response or variant, and tests such as the Rorschach or TAT that are both figural and free-response. The HyperCard language provides a variety of promising techniques useful for microcomputer test administration.
