Social eye gaze modulates processing of speech and co-speech gesture

In human face-to-face communication, language comprehension is a multi-modal, situated activity. However, little is known about how we combine information from different modalities during comprehension, and how perceived communicative intentions, often signaled through visual signals, influence this process. We explored this question by simulating a multi-party communication context in which a speaker alternated her gaze between two recipients. Participants viewed speech-only or speech + gesture object-related messages when being addressed (direct gaze) or unaddressed (gaze averted to other participant). They were then asked to choose which of two object images matched the speaker’s preceding message. Unaddressed recipients responded significantly more slowly than addressees for speech-only utterances. However, perceiving the same speech accompanied by gestures sped unaddressed recipients up to a level identical to that of addressees. That is, when unaddressed recipients’ speech processing suffers, gestures can enhance the comprehension of a speaker’s message. We discuss our findings with respect to two hypotheses attempting to account for how social eye gaze may modulate multi-modal language comprehension.     

Age Differences in Proactive Newcomer Socialization Strategies in Two Populations

We investigated the role of age as a predictor of newcomer socialization behaviors, and documented relationships between specific strategies and subsequent role-relevant outcomes. Academic and retail newcomer populations were each surveyed over three time periods. A negative relationship was found between age and covert forms of information seeking in both samples. Further, the use of covert information seeking was related to lower subsequent levels of role clarity and job satisfaction.     

What is "marked" in visual marking? Evidence for effects of configuration in preview search

Visual search for a conjunction target is facilitated when distractor sets are segmented over time: the preview benefit Watson and Humphreys (1997) suggested that this benefit involved inhibition of old items (visual marking, VM). We investigated whether the preview benefit is sensitive to the configuration of the old distractors. Old distractors changed their location prior to the occurrence of the new items, while also either changing or maintaining their configuration. Configuration changes disrupted search. The results are consistent with object-based VM, which is sensitive to the configuration of old stimuli.     

Associations between emotional avoidance,anxiety sensitivity,and reactions to an observational fear challenge procedure

Research has shown that emotional avoidance and anxiety sensitivity are associated with more self-reported fear and distress in response to laboratory fear challenge procedures. The present study aimed to expand upon this work and examined how emotional avoidance and anxiety sensitivity are related to emotional and physiological responses to an observational fear challenge procedure. To accomplish this aim, a carefully screened, non-clinical sample (N = 43) was administered the Acceptance and Action Questionnaire (AAQ), a measure of emotional avoidance, and the Anxiety Sensitivity Index (ASI). Participants then engaged in an observational fear challenge paradigm. During the fear challenge, participants watched mock panic attacks while emotional (e.g., fear and panic) and skin conductance levels were assessed. Consistent with expectation, emotional avoidance and anxiety sensitivity were positively associated with more self-reported fear and more severe panic symptoms to the challenge procedure. However, anxiety sensitivity was more highly associated with self-reported fear and panic symptoms in response to the challenge procedure than emotional avoidance. Emotional avoidance and anxiety sensitivity were not associated with levels of physiological arousal to the observational fear challenge procedure. Discussion focuses on the interplay between emotional avoidance, anxiety sensitivity, and the development of vicarious fear responses and how these constructs may contribute to the pathogenesis of anxiety disorders.     

Associations between Maternal Physical Discipline and Peer Victimization among Hong Kong Chinese Children: The Moderating Role of Child Aggression

This study examines the relation between maternal physical discipline and victimization by peers, as moderated by child aggression. The sample consisted of 211 Hong Kong Chinese children (98 boys, 113 girls; average age of 11.9). Physical discipline was assessed with a questionnaire completed by mothers, and victimization by peers and aggression were measured using a peer nomination inventory. Latent variable models revealed a moderately strong link between children’s experiences with maternal physical discipline and peer victimization, but this effect held only for children who were also high on aggression. These results highlight the interplay between harsh home environments and child aggression and their contributions to the child’s adjustment in the peer group.     

The Body of Christ has AIDS: The Catholic Church Responding Faithfully to HIV and AIDS in Papua New Guinea

Using the example of the Catholic Church in Papua New Guinea (PNG), I detail how, through praxis, it has brought to life a living theology of HIV and AIDS. In this way, the Catholic Church in PNG is responding faithfully to the epidemic. As a Christian country with a generalised HIV epidemic, where the body of an individual is reconstituted through the liturgical practices of baptism and Eucharist, theologically, in PNG the body of Christ has AIDS. In order to examine the ways in which the Catholic Church in PNG has responded faithfully to the Christian body with AIDS, I do so in relation to the three theological virtues of faith, hope and love.

Ockham Efficiency Theorem for Stochastic Empirical Methods

Ockham’s razor is the principle that, all other things being equal, scientists ought to prefer simpler theories. In recent years, philosophers have argued that simpler theories make better predictions, possess theoretical virtues like explanatory power, and have other pragmatic virtues like computational tractability. However, such arguments fail to explain how and why a preference for simplicity can help one find true theories in scientific inquiry, unless one already assumes that the truth is simple. One new solution to that problem is the Ockham efficiency theorem (Kelly 2002, Minds Mach 14:485–505, 2004, Philos Sci 74:561–573, 2007a, b, Theor Comp Sci 383:270–289, c, d; Kelly and Glymour 2004), which states that scientists who heed Ockham’s razor retract their opinions less often and sooner than do their non-Ockham competitors. The theorem neglects, however, to consider competitors following random (“mixed”) strategies and in many applications random strategies are known to achieve better worst-case loss than deterministic strategies. In this paper, we describe two ways to extend the result to a very general class of random, empirical strategies. The first extension concerns expected retractions, retraction times, and errors and the second extension concerns retractions in chance, times of retractions in chance, and chances of errors.     

Cross-Category Friendships and Postformal Thought among College Students

Theories of postformal thought (PFT) suggest that cognitive development is enhanced by social interactions where differences must be negotiated. Friendships provide the potential for complex social interactions and are an ideal context in which to explore the relation between cognitive development and the negotiation of social differences. The present research is the first to directly explore the relation between close cross-category friendships and level of postformal cognitive reasoning among college students. Participants from two universities completed questionnaires assessing PFT and friendship characteristics. Results indicate that individuals reported more same-category versus cross-category friendships. This was true for sex, ethnicity, social class, sexual orientation, and age. In addition, individuals high in PFT had more social category differences in their existing close friendships than individuals low in PFT.     

Religion and United States Physicians’ Opinions and Self-Predicted Practices Concerning Artificial Nutrition and Hydration

This study surveyed 1,156 practicing US physicians to examine the relationship between physicians’ religious characteristics and their approaches to artificial nutrition and hydration (ANH). Forty percent of physicians believed that unless a patient is imminently dying, the patient should always receive nutrition and fluids; 75 % believed that it is ethically permissible for doctors to withdraw ANH. The least religious physicians were less likely to oppose withholding or withdrawing ANH. Compared to non-evangelical Protestant physicians, Jews and Muslims were significantly more likely to oppose withholding ANH, and Muslims were significantly more likely to oppose withdrawing ANH.
