Perceptual order and the effect of vocalic context on fricative perception

This three-part study demonstrates that perceptual order can influence the integration of acoustic speech cues. In Experiment 1, the subjects labeled the [s] and [∫] in natural FV and VF syllables in which the frication was replaced with synthetic stimuli. Responses to these “hybrid” stimuli were influenced by cues in the vocalic segment as well as by the synthetic frication. However, the influence of the preceding vocalic cues was considerably weaker than was that of the following vocalic cues. Experiment 2 examined the acoustic bases for this asymmetry and consisted of analyses revealing that FV and VF syllables are similar in terms of the acoustic structures thought to underlie the vocalic context effects. Experiment 3 examined the perceptual bases for the asymmetry. A subset of the hybrid FV and VF stimuli were presented inreverse, such that the acoustic and perceptual bases for the asymmetry were pitted against each other in the listening task. The perceptual bases (i.e., the perceived order of the frication and vocalic cues) proved to be the determining factor. Current auditory processing models, such as backward recognition masking, preperceptual auditory storage, or models based on linguistic factors, do not adequately account for the observed asymmetries.     

When do ego threats lead to self-regulation failure? Negative consequences of defensive high self-esteem

High self-esteem (HSE) is increasingly recognized as heterogeneous. By measuring subtypes of HSE, the present research reevaluates the finding that HSE individuals show poor self-regulation following ego threat (Baumeister, Heatherton, & Tice, 1993). In Experiment 1, participants with HSE showed poor self-regulation after ego threat only if they also were defensive (high in self-presentation bias). In Experiment 2, two measures--self-presentation bias and implicit self-esteem--were used to subtype HSE individuals as defensive. Both operationalizations of defensive HSE predicted poor self-regulation after ego threat. The results indicate that (a) only defensive HSE individuals are prone to self-regulation failure following ego threat and (b) measures of self-presentation bias and implicit self-esteem can both be used to detect defensiveness.     

Approach/avoidance motivation, message framing, and health behavior: understanding the congruency effect

Health messages framed to be congruent with individuals’ approach/avoidance motivations have been found to be more effective in promoting health behaviors than health messages incongruent with approach/avoidance motivations. This study examines the processes underlying this congruency effect. Participants (undergraduate students, N=67) completed a measure of approach/avoidance orientation (the BIS/BAS scales) and read either a gain- or loss-framed message promoting dental flossing. Results demonstrated a congruency effect: Participants who read a congruently framed message had greater flossing efficacy, intended to floss more, and used more dental flosses than did the participants who read an incongruent message. Moreover, intention to perform the behavior predicted the congruency effect and self-efficacy mediated participants’ intentions to perform the health behavior. Discussion centers on the role of personality factors and situational factors in models of behavior change.

Linking work: from violence to subjectivization

For certain adolescents, the eruption of puberty sometimes carries the risk of a break in their psychic life: a break in their impression of continuity in existence, in the investment of their inner world, and in their relation to external objects. When these adolescents are unable to tolerate the discontinuity that accompanies the experience of adolescence, this can lead to pathologies of compulsive breaking away, depression, violence, or psychosis. Linking work, on the contrary, enables adolescence to become a transforming process on the psychic level and contributes to the dynamic character of the therapeutic process.     

The "style scheme" grounds perception of paintings

We studied the formation of style scheme (identification of the style that characterizes an artist) presenting 100 participants aesthetic visual stimuli. Participants were Spanish university students who volunteered: 72 women, 28 men of mean age 22.8 yr. Among those 50 were enrolled in History of Art and 50 students in Psychology. Stimuli belonged to different categories--High Art (pictures of well-known artists, like Van Gogh)/Popular Art (decorative pictures like Christmas postcards) and Representational (pictures with explicit meaning content, like a landscape)/Abstract (pictures without explicit meaning content, like Pollock's colored stains). Analysis using Signal Detection Theory techniques focused on how participants discriminate representational and abstract pictures. With High Art stimuli, participants can better discriminate representational paintings than abstract ones. However, the difference in discrimination between representational and abstract pictures diminishes among participants studying History of Art. It seems that prior education in art favors forming style schemes and to some extent enables the participant to detect the "meaning" in High Art abstract paintings.     

Interrupting recognition memory: Tests of a criterion-change account of the revelation effect

The revelation effect is evidenced by an increase in positive recognition responses when the test probe is immediately preceded by an unrelated problem-solving task. As an alternative to familiarity-based explanations of this effect (Hicks & Marsh, 1998; Westerman & Greene, 1998), Niewiadomski and Hockley (2001) proposed a decision-based account in which it is assumed that the problem-solving task displaces the study list context in working memory, leading subjects to adopt a more liberal recognition criterion. In the present study, we show that the revelation effect is seen when the stimulus materials are pure lists of very rare words or nonwords. In contrast, for mixed lists of common words and very rare words or nonwords, the revelation effect is found for common words but disappears for very rare words and nonwords. We argue that, in mixed lists, the liberal decision bias following the revelation task and the criterion changes between common words and very rare words and nonwords serve to offset each other.     

Joseph and His Brothers: A Biblical Paradigm for the Optimal Handling of Traumatic Stress

The long-lasting effects of emotional trauma and the important role of unconscious emotional defenses have become increasingly recognized only in the past century. Yet their role is actually manifest, although still overlooked, in one of the most well-known of biblical stories. This paper presents the story of Joseph and his brothers, and the important lessons it teaches about unconscious defenses and the optimal handling of emotional trauma.     

More than mere mimicry? The influence of emotion on rapid facial reactions to faces

Within a second of seeing an emotional facial expression, people typically match that expression. These rapid facial reactions (RFRs), often termed mimicry, are implicated in emotional contagion, social perception, and embodied affect, yet ambiguity remains regarding the mechanism(s) involved. Two studies evaluated whether RFRs to faces are solely nonaffective motor responses or whether emotional processes are involved. Brow (corrugator, related to anger) and forehead (frontalis, related to fear) activity were recorded using facial electromyography (EMG) while undergraduates in two conditions (fear induction vs. neutral) viewed fear, anger, and neutral facial expressions. As predicted, fear induction increased fear expressions to angry faces within 1000 ms of exposure, demonstrating an emotional component of RFRs. This did not merely reflect increased fear from the induction, because responses to neutral faces were unaffected. Considering RFRs to be merely nonaffective automatic reactions is inaccurate. RFRs are not purely motor mimicry; emotion influences early facial responses to faces. The relevance of these data to emotional contagion, autism, and the mirror system-based perspectives on imitation is discussed.     

Short-term predictive effects of the looming cognitive style on anxiety disorder symptoms under restrictive methodological conditions

The looming cognitive style (LCS), an overarching cognitive vulnerability for anxiety syndromes, pertains to a tendency to construct dynamic expectations (mental scenarios, images) of negative events as progressively increasing in danger and rapidly escalating in risk. This study tested the hypothesis that the LCS has functions as a cognitive antecedent and moderator for even short-term changes over a brief time interval in anxiety syndromes (worry, obsessive-compulsive disorder (OCD) symptoms, social anxiety, general anxiety) under restrictive methodological conditions. These included: (a) a one-week interval during which very little changes in anxiety were observed, and (b) controlling for participants' depression and intolerance of uncertainty. As hypothesized by our model, the looming cognitive style predicted short-term changes in worry and OCD symptoms over the week interval, and tended to predict changes in social (audience) anxiety. This style also functioned as a moderator and predicted changes in OCD symptoms among participants already high on this anxiety outcome. Intolerance of uncertainty predicted changes in social (audience) anxiety but not changes in OCD symptoms or worry. These findings support the looming vulnerability theory of anxiety, and encourage further attention into the possible role of the LCS as a cognitive antecedent and moderator of changes in a spectrum of anxiety syndromes.     

The effects of message quality and congruency on perceptions of tailored health communications

Recent research has documented the effectiveness of tailoring health behavior change messages to characteristics of the recipients, but little is known about the processes underlying these effects. Drawing from the elaboration likelihood model (Petty & Cacioppo, 1986), we examined the role of message scrutiny in moderating the congruency effect (Mann, Sherman, & Updegraff, 2004). One hundred and thirty-six undergraduate participants read either a strong or weak message promoting regular dental flossing with a frame (gain vs. loss) that either matched or mismatched their motivational orientation (approach vs. avoidance). Results showed that participants were sensitive to argument quality in the matched but not mismatched conditions. Further, argument quality moderated the effect of congruency on participants’ attitudes and perceived norms regarding flossing, as well as their subsequent self-reported flossing behavior. Results suggest that increased message scrutiny underlies message tailoring effects.
