Agent-based Theories of Right Action

In this paper, I develop an objection to agent-based accounts of right action. Agent-based accounts of right action attempt to derive moral judgment of actions from judgment of the inner quality of virtuous agents and virtuous agency. A moral theory ought to be something that moral agents can permissibly use in moral deliberation. I argue for a principle that captures this intuition and show that, for a broad range of other-directed virtues and motives, agent-based accounts of right action fail to satisfy this principle.     

Behavioral skills training in scent detection research: Interactions between trainer and animal behavior

Animal trainers working in scent detection programs are responsible for arranging training contingencies as well as for observing and recording animal behavior. We provided behavioral skills training (BST) to animal trainers working with scent detection rats to improve the treatment integrity of scent‐detection research sessions. We evaluated the trainers' behavior at baseline and during the sequential introduction of each component of BST (instructions, modeling, and feedback). We observed incremental improvements in treatment integrity with the introduction of each BST component. Posttraining probes revealed that these improvements were sustained at least 3 weeks post‐BST. As the trainers' behavior was modified during BST, we observed decrements in measures of rat performance. We discuss the nature of these interactions and their implications for the use of BST in scent detection research and in situations in which intervention with one party produces concomitant effects on the behavior of another.     

Intercultural Study of Personal Space: A Case Study

The study of intercultural differences in personal space attempts to identify factors that could be helpful in guiding people from different cultures to live and work together in international ventures. The objective of this research was to measure interpersonal distance in a cross-cultural environment. Twenty-three participants classified in 4 cultural groups answered an 11-questions interview where the personal distance and orientation between seated interactants were measured. Results showed that Anglo Saxons used the largest zone of personal space, followed by Asians, then Caucasians, and, as expected, Mediterraneans and Latinos used the shortest distance. Where Latinos adopt a face-to-face position, Caucasians tend to orient themselves to the side of the interviewer, which has an impact on interpersonal communication.     

Sex Differences in Effectiveness of Extended-Release Stimulant Medication among Adolescents with Attention-Deficit/Hyperactivity Disorder

This study examined whether adolescent females with attention-deficit/hyperactivity disorder (ADHD) are differentially responsive than their male counterparts to extended-release stimulant medications. This investigation may bear special importance for an adolescent (as opposed to child) population, because hormonal and metabolism differences between sexes are most likely to emerge at this time. Male (n = 19) and female (n = 16) adolescents, ages 16–19 with ADHD, participated in a randomized, double-blind crossover study evaluating the effectiveness of osmotic-release methylphenidate, extended release amphetamine salts, placebo, and routine limited medication regimen. Medication efficacy was evaluated using ADHD symptom ratings from adolescent self-report and parent report, along with objective measures of inattention and hyperactivity/impulsivity during driving performance and neuropsychological tasks. Males and females were largely equivalent in impairment, and medication was similarly effective in reducing symptoms. No interactions were found between sex and medication on any measure of effectiveness or side effects. This finding suggests that the efficacy and tolerability of extended-release stimulant medications is equivalent for male and female adolescents with ADHD.     

Preventing Suicide at Suicide Hotspots: A Case Study from Australia

The Gap Park Self‐Harm Minimisation Masterplan project is a collaborative attempt to address jumping suicides at Sydney's Gap Park through means restriction, encouraging help‐seeking, and increasing the likelihood of third‐party intervention. We used various data sources to describe the Masterplan project's processes, impacts, and outcomes. There have been reductions in reported jumps and confirmed suicides, although the trends are not statistically significant. There has been a significant increase in police call‐outs to intervene with suicidal people who have not yet reached the cliff's edge. The collaborative nature of the Masterplan project and its multifaceted approach appear to be reaping benefits.     

Teaching Prosocial Behavior to Typically Developing Toddlers

Toddlers in day care have more toy conflicts, aggression, and peer-inflicted injuries than any other age group. Toddlers are also capable of turn-taking and affectionate behavior, but exhibit these prosocial behaviors less often than aggression and toy-taking. We explored the usefulness and feasibility of contextual and teacher-directed social skills intervention for increasing toddlers' turn-taking and affectionate behavior to peers. Results showed that adding tangible consequences to a basic package of contextual arrangement, prompts, and praise was the most effective strategy for increasing both turn-taking and affection. Aggression decreased when affection or turn-taking increased.     

STM Experimenter: Using HyperCard and MacRecorder in short-term memory experiments

We describe a Macintosh program for the presentation of spoken word lists in short-term memory (STM) experiments. The program was developed with the use of HyperCard and MacRecorder. Parameters such as rate of item presentation, number of items per trial, and number of trials per block may be adjusted by the experimenter. The program features high-quality digitized sound, trial-to-trial word list randomization, and data logging. Computer-based experimentation offers several advantages over traditional approaches that involve tape recordings or lists read aloud by the experimenter. Methodological improvements afforded by computer-controlled item administration are discussed.     

Self-reports of depression and state-trait anxiety: evidence for differential assessment.

Several researchers have found anxiety and depression to be indistinguishable in nonclinical samples and have suggested that both constructs may be components of a general psychological distress process. Another possibility is that overlap is due to the psychometric limitations of scales used. A series of exploratory factor analyses were conducted in a nonclinical sample (N = 605) using the Beck Depression Inventory (BDI; Beck, 1978), the State-Trait Anxiety Inventory (STAI; Spielberger, 1983), and the Endler Multidimensional Anxiety Scales (EMAS; Endler, Edwards, & Vitelli, 1991). Both state and trait anxiety and depression could be differentiated with the BDI and the EMAS but not with the STAI. Some theoretical models of negative affectivity or general psychopathology may be premature.     

A dental roll technique for the measurement of salivary activity

A discussion of the development of a method for the analysis of salivary activity is presented. Results gained using this new method are compared with those obtained using a whole-mouth spitting technique. The application of the new method in real-world situations is indicated. Norms are presented for measures of salivary flow, pH, and salivary ion concentration based on experimental studies of a female working population.
