Effects of antecedent variables on disruptive behavior and accurate responding in young children in outpatient settings

The effects of manipulations of task variables on inaccurate responding and disruption were investigated with 3 children who engaged in noncompliance. With 2 children in an outpatient clinic, task directives were first manipulated to identify directives that guided accurate responding; then, additional dimensions of the task were manipulated to evaluate their influence on disruptive behavior. With a 3rd child, similar procedures were employed at school. Results showed one-step directives set the occasion for accurate responding and that other dimensions of the task (e.g., preference) functioned as motivating operations for negative reinforcement.     

Hume’s Solution of the Goodman Paradox and the Reliability Riddle (Mill’s problem)

Many solutions of the Goodman paradox have been proposed but so far no agreement has been reached about which is the correct solution. However, I will not contribute here to the discussion with a new solution. Rather, I will argue that a solution has been in front of us for more than two hundred years because a careful reading of Hume’s account of inductive inferences shows that, contrary to Goodman’s opinion, it embodies a correct solution of the paradox. Moreover, the account even includes a correct answer to Mill’s question of why in some cases a single instance is sufficient for a complete induction, since Hume gives a well-supported explanation of this reliability phenomenon. The discussion also suggests that Bayesian theory by itself cannot explain this phenomenon. Finally, we will see that Hume’s explanation of the reliability phenomenon is surprisingly similar to the explanation given lately by a number of naturalistic philosophers in their discussion of the Goodman paradox.     

The Disgust Scale: item analysis, factor structure, and suggestions for refinement

In the 4 studies presented (N = 1,939), a converging set of analyses was conducted to evaluate the item adequacy, factor structure, reliability, and validity of the Disgust Scale (DS; J. Haidt, C. McCauley, & P. Rozin, 1994). The results suggest that 7 items (i.e., Items 2, 7, 8, 21, 23, 24, and 25) should be considered for removal from the DS. Secondary to removing the items, exploratory and confirmatory factor analyses revealed that the DS taps 3 dimensions of disgust: Core Disgust, Animal Reminder Disgust, and Contamination-Based Disgust. Women scored higher than men on the 3 disgust dimensions. Structural modeling provided support for the specificity of the 3-factor model, as Core Disgust and Contamination-Based Disgust were significantly predictive of obsessive- compulsive disorder (OCD) concerns, whereas Animal Reminder Disgust was not. Results from a clinical sample indicated that patients with OCD washing concerns scored significantly higher than patients with OCD without washing concerns on both Core Disgust and Contamination-Based Disgust, but not on Animal Reminder Disgust. These findings are discussed in the context of the refinement of the DS to promote a more psychometrically sound assessment of disgust sensitivity.     

Ethnic, gender, and socioeconomic differences in young adults' self-disclosure: who discloses what and to whom?

Self-disclosure of feelings, thoughts, experiences, and beliefs is central to our lives as social beings and has numerous implications for relationships and health. Although prior research suggests that men and underrepresented groups disclose less, ethnicity is conflated with socioeconomic status and there are few data regarding the types of information that different groups disclose and whether this information is disclosed equally to different people. The current study measured self-disclosure in 203 young adults (50% African American, 50% female), in respect of seven domains and 10 interpersonal targets. As expected, disclosure was not lower among African Americans once income was controlled, although both ethnicity and gender interacted with domain of disclosure and interpersonal target. Importantly, young men and African Americans reported disclosing less in the context of more intimate relationships. Together, these results suggest that income may be as important in predicting low disclosure as ethnicity or gender and that lower disclosure in low-disclosing groups is particularly evident in intimate relationships. Results are discussed in terms of their implications for patterns of interpersonal relating and physical and mental health processes.     

Variations of the flanker paradigm: Assessing selective attention in young children

The development of selective attention and associated self-regulatory processes was assessed in young children, ages 4, 5, and 6, through the use of three alternative versions of the flanker paradigm utilizing colors, shapes, and fish. These variations were used to examine the influence of task differences on children’s performance. The presence of cognitive self-regulatory strategies in young children was also assessed. Significant flanker interference effects, marked by significant task-linked response time differences, were found across all three versions of the paradigm. Although a significant portion of children demonstrated self-regulatory abilities, not every participant demonstrated the specific strategies of self-monitoring and response control. Furthermore, these differences were evident across all age groups. The implications of these results are discussed within the theoretical context of task development, taking into consideration the need to modify computerized attention paradigms for use with young children in order to reliably measure cognitive constructs across children and adults.     

How are base‐rates used,when they are used: a comparison of additive and Bayesian models of base‐rate use

Previous research has uncovered many conditions that encourage base‐rate use. The present research investigates how base‐rates are used when conditions are manipulated to encourage their use in the lawyer/engineer paradigm. To examine the functional form of the response to base‐rate, a factorial design was employed in which both base‐rate and the individuating information were varied within‐subject. We compared the performance of several models of base‐rate use, including a model that allows base‐rate and individuating information to be combined in a strictly additive fashion, and a model which presumes that respondents use Bayes' Rule in forming their judgments. Results from 1493 respondents showed that the additive model is a stronger predictor of base‐rate use than any other model considered, suggesting that the base‐rate and individuating information are processed independently in the lawyer/engineer paradigm. A possible mechanism for this finding is discussed. Copyright © 1999 John Wiley & Sons, Ltd.
