Learning General Phonological Rules From Distributional Information: A Computational Model

Phonological rules create alternations in the phonetic realizations of related words. These rules must be learned by infants in order to identify the phonological inventory, the morphological structure, and the lexicon of a language. Recent work proposes a computational model for the learning of one kind of phonological alternation, allophony (Peperkamp, Le Calvez, Nadal, & Dupoux, 2006). This paper extends the model to account for learning of a broader set of phonological alternations and the formalization of these alternations as general rules. In Experiment 1, we apply the original model to new data in Dutch and demonstrate its limitations in learning nonallophonic rules. In Experiment 2, we extend the model to allow it to learn general rules for alternations that apply to a class of segments. In Experiment 3, the model is further extended to allow for generalization by context; we argue that this generalization must be constrained by linguistic principles.     

Implicit Attitudes as Potential Protection From Risky Sex: Predicting Condom Use With the IAT

The Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998) has become a popular tool for measuring implicit attitudes toward 2 contrasting concepts. In this study, we suggest including a neutral category (trees) to capture implicit evaluations of a single target attitude object. Using such a technique to measure implicit attitudes toward condoms, we predicted and found that explicit attitudes were related to intended condom use in situations that allow for controlled and deliberative processing, but implicit attitudes were related to intended condom use when automatic processing presides. Implications for such implicit and explicit attitude-behavior relations are discussed in the context of sexual risk-taking.     

Recollections of Being in Child Expressive Arts Group Therapy: A Qualitative Study of Adult Former Clients’ Conceptions of Their Therapy as Children

The current study aims to explore, through the eyes of adult former clients, the experience of being in expressive arts group therapy (EAGT) as a child. By focusing on the memories of adults, the study allowed the exploration of former clients’ understanding of what the therapy was about and its effects on their lives. Semi-structured open-ended interviews were conducted with 20 adult former clients who, as children, had participated for at least one year in EAGT. Findings point toward the background of the empathic, attuned, safety, together with the fostering of the capacity to enter into spontaneous creative states, as central themes in participant’ recollections of the therapeutic process. Further findings relate to the implicit and long-term quality of the therapeutic effect.     

Psychosocial mediators of a theory-based resistance training maintenance intervention for prediabetic adults

Objective: Examine psychosocial mediators of the effects of high vs. low-dose resistance training (RT) maintenance interventions among older (ages 50–69), overweight and pre-diabetic adults.

Design: Participants (N = 123) completed a three-month supervised RT initiation phase and were subsequently randomised (time 1) to high or low-dose six-month unsupervised RT maintenance interventions (time 2), followed by a six-month no-contact phase (time 3).

Main Outcome Measures: Online measures of putative mediators and RT behaviour.

Results: RT intervention condition (high vs. low dose) had significant effects on change from time 1 to time 2 in behavioural expectation, self-regulation and perceived satisfaction (f² = .04–.08), but not outcome expectancies, RT strategies or behavioural intentions (f² ≤ .02). Change in each of the putative mediators, except for outcome expectancies (f² ≤ .02), had significant effects on RT behaviour at times 2 (f² = .12–.27) and 3 (f² = .23–.40). In a multiple mediation model, behavioural expectation (f² = .11) and self-regulation (f² = .06) mediated the effects of RT intervention condition on time 2 RT behaviour, whereas perceived satisfaction did not (f² = .01). Self-regulation was a significant mediator of intervention effects on time 3 RT behaviour (f² = .11), but behavioural expectation and perceived satisfaction were not (f² = .04).

Conclusions: Findings suggest that behavioural expectation and self-regulation are appropriate targets for RT maintenance interventions among at-risk older adults.     

Becoming a vampire without being bitten: the narrative collective-assimilation hypothesis

We propose the narrative collective-assimilation hypothesis--that experiencing a narrative leads one to psychologically become a part of the collective described within the narrative. In a test of this hypothesis, participants read passages from either a book about wizards (from the Harry Potter series) or a book about vampires (from the Twilight series). Both implicit and explicit measures revealed that participants who read about wizards psychologically became wizards, whereas those who read about vampires psychologically became vampires. The results also suggested that narrative collective assimilation is psychologically meaningful and relates to the basic human need for connection. Specifically, the tendency to fulfill belongingness needs through group affiliation moderated the extent to which narrative collective assimilation occurred, and narrative collective assimilation led to increases in life satisfaction and positive mood, two primary outcomes of belonging. The implications for the importance of narratives, the need to belong to groups, and social surrogacy are discussed.     

On some limits of hypothetical thinking

Faced with extreme demands, hypothetical thinking runs the danger of total failure. Paradoxical propositions such as the Liar (“I am lying”) provide an opportunity to test it to its limits, while the Liar's nonparadoxical counterpart, the Truthteller (“I am telling the truth”), provides a useful comparison. Two experiments are reported, one with abstract materials (“If I am a knave then I live in Emerald City”) and one with belief-laden materials (a judge says: “If I am a knave then I enjoy pop music”). In both experiments, conditionals with Truthteller-type antecedents were “collapsed” to responses of conditional probability closely resembling estimates of control items. Liar-type antecedents, in contrast, dramatically weakened belief in conditionals in which they were embedded. The results are discussed in the framework of the theory of hypothetical thinking.     

Moderators of Social Power Use for In‐Group/Out‐Group Targets: An Experimental Paradigm1

Studies of social power use have frequently employed self‐report instruments that are prone to response bias. In the present study, an experimental design was conducted in which 100 participants were asked to gain compliance from in‐group and out‐group members. We tested whether harsh tactics—often used for elevating self‐image at the dyadic level—also provide a means for gaining advantage at the group level. For this purpose, self‐esteem and self‐efficacy were examined as possible moderators. Findings indicated that self‐esteem interacted with target group: Low self‐esteem participants used harsh tactics more frequently toward in‐group than out‐group members; and moderate and high self‐esteem participants used harsh tactics more frequently toward out‐group than in‐group members. The process involved in this interaction is discussed.     

A friend is a present you give to your “Self”: Avoidance of intimacy moderates the effects of friends on self-liking

The current research proposes that thinking about friends improves feelings about the self and does so differentially depending on avoidance of intimacy. Based on previous findings that individuals who avoid intimacy in relationships (avoidant individuals) contrast their self-concepts with primed friends whereas those who pursue intimacy in relationships (non-avoidant individuals) assimilate their self-concepts to primed friends [Gabriel, S., Carvallo, M., Dean, K., Tippin, B. D., & Renaud, J. (2005). How I see “Me” depends on how I see “We”: The role of avoidance of intimacy in social comparison. Personality and Social Psychology Bulletin, 31, 156-157], we predicted that friends who embody negative aspects of self would lead avoidant individuals to like themselves more, whereas friends who embody positive aspects of self would lead non-avoidant individuals to like themselves more. A pretest determined that good friends were seen as more similar to positive and ideal aspects of the self, whereas friends about whom participants had more mixed feelings (ambivalent friends) were seen as more similar to disliked and feared aspects of the self. Four experiments supported the main hypotheses. In Experiment 1, non-avoidant individuals like themselves more when good friends were primed. In Experiment 2, avoidant individuals like themselves more when ambivalent friends were primed. In Experiment 3, non-avoidant individuals liked themselves better after thinking about a friend’s positive traits, whereas avoidant individuals liked themselves better after thinking about a friend’s negative traits. In Experiment 4, all individuals under self-esteem threat strategically brought friends to mind who would help them like themselves more.     

Rabbis and Health: A Half-Century Review of the Mental and Physical Health Care Literature:1950–1999

Electronic searches were conducted on PubMed and the American Psychological Association's database (PsycINFO) for articles that discussed the role of rabbis in relation to some aspect of healthcare. The two searches were conducted in each electronic database using the search-terms: (1) (rabbi OR rabbinical OR synagogue) OR (2) (Judaism OR Jewish) AND (clergy OR chaplain). Articles were classified by the year of their publication, professional discipline, type of journal (either religious or secular), and type of article: either research, or narrative and expositional. Rabbis were discussed most often in psychology, psychiatry, and behavior-related fields, and close to two-thirds of the articles dealt with mental health concerns. A statistically significant increase in articles across decades was found in the secular journals, r=.98, p≤.01, with over 70% of the articles about rabbis in the secular journals being published between 1980 and 1999. Many of the articles addressed collaboration between rabbis, psychiatrists, and other and mental health professionals and discussed previously identified themes related to professional collaboration and referral.
