The use of sequential probabilities in the segmentation of speech

The present investigation addresses the possible utility of sequential probabilities in the segmentation of spoken language. In a series of five word- spotting and two control lexical decision experiments, high- versus low-probability consonant-vowel (Experiments 1, 2, 5, and 7) and vowel-consonant (Experiments 1, 3, 4, and 6) strings were presented either in the nonsense contexts of target words (Experiments 1–3) or within the target words themselves (Experiments 4–7). The results suggest that listeners, at least for sequences in the onset position, indeed use sequential probabilities as cues for segmentation. The probability of a sound sequence influenced segmentation more when the sequence occurred within the target words (Experiments 4–7 vs. Experiments 1–3). Furthermore, the effects were reliable only when the sequences occurred in the onset position (Experiments 1, 2, 5, and 7 vs. Experiments 1, 3, 4, and 6).     

Perceptions of Responsibility and Mental Health Help-Seeking Among Psychologically Distressed Older Adults

This study explored the perceptions of responsibility for the cause and the solution of problems and the models of helping (or helping orientations) characterizing a sample of 319 community-dwelling, psychologically distressed older adults. All participants were referred for psychotherapy and had either accepted or rejected their referrals. We investigated whether the models distinguished acceptors and rejecters of psychotherapy referrals and whether they were differentially associated with help-seeking from nontherapist helpers. Results indicated that the preponderance of respondents subscribed to the moral and compensatory models. The compensatory model was associated with rejection of referrals, whereas the moral model was associated with increased help-seeking both from mental health professionals and from other formal and informal helpers. Implications of the findings for promoting older adults' utilization of mental health services are discussed.     

Effects of tailoring ingredients in auditory persuasive health messages on fruit and vegetable intake

Objective: Health messages can be tailored by applying different tailoring ingredients, among which personalisation, feedback and adaptation. This experiment investigated the separate effects of these tailoring ingredients on behaviour in auditory health persuasion. Furthermore, the moderating effect of self-efficacy was assessed.

Design: The between-participants design consisted of four conditions. A generic health message served as a control condition; personalisation was applied using the recipient’s first name, feedback was given on the personal state, or the message was adapted to the recipient’s value.

Main outcome measures: The study consisted of a pre-test questionnaire (measuring fruit and vegetable intake and perceived difficulty of performing these behaviours, indicating self-efficacy), exposure to the auditory message and a follow-up questionnaire measuring fruit and vegetable intake two weeks after message exposure (n = 112).

Results: ANCOVAs showed no main effect of condition on either fruit or vegetable intake, but a moderation was found on vegetable intake: When self-efficacy was low, vegetable intake was higher after listening to the personalisation message. No significant differences between the conditions were found when self-efficacy was high.

Conclusion: Individuals with low self-efficacy seemed to benefit from incorporating personalisation, but only regarding vegetable consumption. This finding warrants further investigation in tailoring research.     

Therapist empathy,homework compliance,and outcome in cognitive behavioral therapy for generalized anxiety disorder: partitioning within- and between-therapist effects

Although client-perceived therapist empathy relates to positive therapy outcomes, including in cognitive behavioral therapy (CBT), little is known about how empathy exerts its ameliorative effect. One possible way is by promoting clients’ subsequent homework compliance, a variable that also predicts positive outcomes in CBT. The present study sought to investigate simultaneously, in the context of 43 therapist–client dyads receiving 15 sessions of CBT for generalized anxiety disorder, (1) the association of early client-perceived therapist empathy (averaged over sessions 1, 3, 5) with mid-treatment client homework compliance (averaged over sessions 6, 8, 10); (2) the association of mid-treatment homework compliance on client posttreatment worry severity; and (3) the indirect effect of early perceived therapist empathy on posttreatment worry through mid-treatment homework compliance. Given that clients were nested within therapists, we examined both within- and between-therapist differences in clients’ ratings of therapist empathy and homework compliance, and tested both of these indices as predictors of the relevant dependent variables in a multilevel model. At the within-therapist level (i.e., differences between clients within a given therapist’s caseload), greater early empathy was associated with greater mid-treatment homework compliance. At the between-therapist level (i.e., differences between therapists across all of their cases), greater between-therapist homework compliance was related to lower posttreatment worry. Finally, homework compliance was not found to mediate the relationship between empathy and posttreatment outcome. The results underscore the importance of parsing client and therapist effects, and are discussed with regard to their training and research implications.     

Quest for Significance and Violent Extremism: The Case of Domestic Radicalization

In the present study, we applied the quest for significance model of radicalization to explain the use of political violence. According to the model, when people experience loss of personal significance (e.g., due to social rejection, achievement failures, or abuse) the motivation to restore significance may push them toward the use of extreme means. We tested this prediction in a sample of individuals who have committed ideologically motivated crimes in the United States (n = 1496). We found that experiences of economic and social loss of significance were separate and positive predictors related to the use of violence by perpetrators of ideologically motivated crimes. We also found evidence that the presence of radicalized others (friends but not family members) in the individuals' social network increased their likelihood of using violence.     

Tailoring visual images to fit: Value creation in persuasive messages

The present studies aimed to extend Regulatory Fit Theory in the domain of persuasive communication by (a) using printed advertisement images without any verbal claim, instead of purely or mostly verbal messages; (b) selecting the images to fit the distinct orientations of regulatory mode rather than regulatory focus; and (c) priming regulatory mode orientation instead of relying on chronic prevalence of either locomotion or assessment orientation. We found that recipients primed with a locomotion orientation experienced fit, and were more persuaded, when exposed to “dynamic” versus “static” visual images; conversely, recipients primed with an assessment orientation experienced fit and were more persuaded when exposed to “static” versus “dynamic” images. Our findings show that the experience of fit can be induced by visual messages, resulting in positive effects in terms of attitude toward product advertisement and estimated price of advertised products.

On the inferential epistemics of trait centrality in impression formation

We provide a novel, inferential, account of the trait centrality phenomenon. We suggest that a trait possesses the property of “centrality” to the extent that it is subjectively deemed to imply other traits. Five studies explore four central elements of this view. First, trait relations can be stored as unidirectional rules (“if X then Y” but not necessarily “if Y then X”). Second, the strength of individuals' lay inference rules determines the effect of traits on impressions. Third, situationally manipulating the strength of lay inference rules influences the impact of traits on impressions. Fourth, the impact of an inference rule is reduced when it is difficult to discern the inference rule and when processing resources are limited. Copyright © 2009 John Wiley & Sons, Ltd.
