When scowling may be a good thing: The influence of anger expressions on credibility

Emotion displays do not only signal emotions but also have social signal value. A study was conducted to test the hypothesis that expressing anger when complaining may lead to positive outcomes for the complainant because anger signals goal obstruction and hence the presence of real harm. The results suggest that the social signal value of anger enhances the credibility of the complainant and hence leads to better compensation, but only when the complaint itself presents room for doubt. For highly justified complaints the additional expression of anger does not add information and is discounted. In contrast, showing an affiliative‐smiling demeanor was found to enhance credibility for both types of complaints. Overall, the present research confirmed the important role of emotion expressions as social signals. Copyright © 2008 John Wiley & Sons, Ltd.     

The effect of time pressure on risky choice behavior

Thirty six subjects chose individually between pairs of gambles under three time pressure conditions: High (8 seconds), Medium (16 seconds) and Low (32 seconds). The gambles in each pair were equated for expected value but differed in variance, amounts to win and lose and their respective probabilities. Information about each dimension could be obtained by the subject sequentially according to his preference.The results show that subjects are less risky under High as compared to Medium and Low time pressure, risk taking being measured by choices of gambles with lower variance or lower amounts to lose and win. Subjects tended to spend more time observing the negative dimensions (amount to lose and probability of losing), whereas under low time pressure they preffered observing their positive counterparts. Information preference was found to be related to choices.Filtration of information and acceleration of its processing appear to be the strategies of coping with time pressure.     

Restorying family therapy

This article describes a multi-systemic model of therapy developed by the author over the past decade and summarizes the main products of this project: Explication of key family systems notions, strategic family play therapy, multi-systemic therapy, and culturally-competent family therapy. The model incorporates beyond the family system, culture, wider ecosystems, psychodynamics, and the individual's neuropsychological, cognitive, and socio-emotional development. The model enables the therapist to design flexible multimodal interventions.     

Guilt, guilt-evoking events, depression, and eating disorders

A long theoretical tradition has linked guilt with internalizing disorders. We find no evidence, however, that a greater personality proclivity for guilt is related to depression or eating disturbances as reported by 85 female undergraduates. Females also described guilt-producing incidents involving school versus eating and exercise. We examined reactions to the events including guilt feelings and perceived effectiveness in alleviating these feelings, intropunitive responses, action tendencies, and rationalizations. Both depression and eating disturbances were unrelated to guilt feelings over school, but were related to guilt feelings over eating and exercise. Ineffective alleviation of guilt feelings in both domains was correlated with depression and greater eating disturbances. Women who reacted to guilt-producing events with fewer intropunitive responses such as rumination and self-hatred, and by confiding in others, distancing, and rationalizing their actions through justifications and excuses were less likely to have eating disturbances.     

The Ethics of De-Extinction

“de-extinction” refers to the process of resurrecting extinct species by genetic methods. This science-fiction-sounding idea is in fact already in early processes of scientific implementation. Although this recent “revival of the dead” raises deep ethical questions, the ethics of de-extinction has barely received philosophical treatment. Rather than seeking a verdict for or against de-extinction, this paper attempts an overview and some novel analyses of the main ethical considerations. Five dimensions of the ethics of de-extinction are explored: (a) the possible contribution of de-extinction to promoting ecological values, (b) the deontological argument that we owe de-extinction to species we rendered extinct, (c) the question of “playing God” through de-extinction, (d) the utilitarian perspective, and (e) the role of aesthetic considerations in the ethics of de-extinction. A general feature arising from the paper’s discussion is that, due to de-extinction’s special character, it repeatedly tests the limits of our ethical notions.     

Word associations are formed incidentally during sentential semantic integration

Sentential context facilitates the incidental formation of word associations (e.g., Prior, A., & Bentin, S. (2003). Incidental formation of episodic associations: the importance of sentential context. Memory and Cognition, 31(2), 306-316). The present study explored the mechanism of this effect. In two experiments, unrelated word pairs were embedded in coherent or semantically anomalous sentences. Anomalous sentences included either a local or a global anomaly. During an incidental study phase, participants performed a sentence categorization task. The strength of the incidental associations formed between two nouns jointly appearing in a sentence was probed by gauging their influence on subsequent paired-associate learning and cued recall in Experiment 1, and by assessing their associative priming effect in a subsequent unexpected explicit recognition test for single words in Experiment 2. In both experiments, significant associative memory was found for noun pairs studied in coherent sentences but not for those appearing in anomalous sentences, regardless of anomaly type. In a sentence rating task, global anomalies yielded less plausible sentences than local anomalies, however both types of anomalies were equally detrimental to the sentence integration process. We suggest that sentence constituents are incidentally associated during sentence processing, particularly as a result of sentence integration and the consolidation of a mental model.     

Attentional and perceptual factors affecting the attentional blink for faces and objects

When 2 different visual targets presented among different distracters in a rapid serial visual presentation (RSVP) are separated by 400 ms or less, detection and identification of the 2nd targets are reduced relative to longer time intervals. This phenomenon, termed the attentional blink (AB), is attributed to the temporary engagement of a limited-capacity attentional system by the 1st target, which reduces resources available for processing the 2nd target. Although AB has been reliably obtained with many stimulus types, it has not been found for faces (E. Awh et al., 2004). In the present study, the authors investigate the underpinnings of this immunity. Unveiling circumstances in which AB occurs within and across faces and other categories, the authors demonstrate that a multichannel model cannot account for the absence of AB effects on faces. The authors suggest instead that perceptual salience of the face within the distracters' series as well as the available resources determine whether or not faces are blinked in RSVP.     

Landau-Kleffner syndrome, electrical status epilepticus in slow wave sleep, and language regression in children

The Landau-Kleffner syndrome (LKS) and electrical status epilepticus in slow wave sleep (ESES) are rare childhood-onset epileptic encephalopathies in which loss of language skills occurs in the context of an epileptiform EEG activated in sleep. Although in LKS the loss of function is limited to language, in ESES there is a wider spectrum of cognitive impairment. The two syndromes are distinct but have some overlap. The relationship between the epileptiform EEG abnormalities and the loss of cognitive function remains controversial, even in LKS which is the most widely accepted as an acquired epileptic aphasia. Language regression also occurs in younger children, frequently in the context of a more global autistic regression. Many of these children have epileptiform EEGs. The term autistic regression with epileptiform EEG has been proposed for these children. Whether these children are part of an extended LKS spectrum is very controversial, because there are differences in age of onset, clinical phenotype, and EEG findings. An understanding of the available data on clinical characteristics, EEG findings, pathology, prognosis, and treatment of these syndromes is essential for further progress in this area.
