A necessity illusion for modal inferences from conditionals

Three experiments examined how people reason about what is possible or necessary when a conditional is true. Participants were asked to indicate whether it was necessary, possible or impossible for a specific instance to conform to one of the truth-table cases (pq, p¬q, ¬pq and ¬p¬q) (¬ = not), given the truth of the conditional. It was found that most participants, inconsistently, judged the pq case as necessary but the ¬pq or ¬p¬q cases as possible. Logically, these two kinds of judgments are contradictory. Moreover, a true conditional doesn’t imply that a specific instance under the conditional must be pq . Therefore, people demonstrate a necessity illusion for pq cases which contradicts their commitment to the possibility of ¬pq or ¬p¬q cases. Existing accounts of conditionals are unable to explain the contradiction and the necessity illusion. We propose an inference dissociation account and explore the theoretical implications of this necessity illusion.     

Parent-Child Interaction Therapy and ADHD: A Case Study With a Hearing Child of a Deaf Father and a Hearing Mother

Parent-Child Interaction Therapy (PCIT) has demonstrated promising evidence in its implementation with deaf and hard-of-hearing (DHH) families. This case study presents the implementation of PCIT with a hearing mother, a deaf father, and their 7-year-old hearing son with Attention-Deficit/Hyperactivity Disorder (ADHD) and oppositional behaviors, using the assistance of certified interpreters. Results documented improvement in child behavior, parenting skills and stress, and parent-child communication. Notably, paternal ratings showed greater improvement across these outcomes than maternal ratings. Overall, PCIT continues to demonstrate its effectiveness as a treatment option for DHH families with children with challenging behaviors. The limitations and implications are discussed.     

Assessing Future Expectations of Low-Income Minority Young Men: Survival-Threats and Positive Expectations

Future expectations, a subset of overall orientation, represent youths’ most realistic appraisals of future outcomes, and has been demonstrated to be associated with a range of health risk behaviors and wellbeing. The current study extends previous measurement efforts to operationalize and measure future expectations by estimating a multidimensional model of future expectations encompassing both positive and survival-based expectations, and using longitudinal data to test the consistency of these constructs over time. The current work uses data from six waves of the Chicago Youth Development Study (n = 338), a sample of African American and Latino young men from low income neighborhoods in an urban center, to test a hypothesized multidimensional structure of future expectations across adolescence. Test retest confirmatory factor analyses from six waves of data covering the mean age range of 12–19 years reveal good model fit for the hypothesized multidimensional model of future expectations at each wave. Strong measurement invariance based on race/ethnicity is established for the multidimensional model. Implications for a latent construct approach to future expectations with low-income racial/ethnic minority young men are discussed.     

Consumers' attributions and brand evaluations in product‐harm crises: The role of implicit theories of personality

This study aims to examine the moderating role of implicit theories of personality in the relationship between corporate recovery strategy (i.e., support versus stonewalling) and consumers' attributions (and brand evaluations). It is suggested that consumers' implicit theories about the fixedness/malleability of personality can affect consumers' attributions and brand evaluations during a product‐harm crisis. In addition, corporate image (i.e., strong versus weak) can moderate the influence of the role of implicit theories of personality. Two experiments were conducted to examine the proposed hypotheses. Results of Experiment 1 show that consumers who endorse entity theory (i.e., entity theorists) are likely to attribute crisis as more internal, stable, and controllable, particularly when they do not have any prior knowledge about the firm. The entity theorists would have more negative brand evaluations than incremental theorists (who endorse incremental theory), when “support” strategy was used by the firm. Results of Experiment 2 show that entity theorists are prone to have more external (internal) and unstable (stable) attributions toward a firm with a strong (weak) corporate image. Furthermore, entity theorists would provide more positive brand evaluations than incremental theorists when “stonewalling” strategy was used by a firm with strong corporate image, but not when “support” strategy was used by a firm with weak corporate image. Managerial implications are provided to managers with regard to product‐harm crisis and recovery strategies. Copyright © 2015 John Wiley & Sons, Ltd.
