Skulking around the dinosaur: Eliciting cues to children's deception via strategic disclosure of evidence

Research has shown that cues to deception are more salient as an effect of strategic use of evidence (SUE) during interviews. This study examined the feasibility of the SUE‐technique for eliciting cues to children's deception. Experiment 1 investigated verbal cues to deception as a function of early vs. late disclosure of evidence. Eighty‐four children (12–14 years) either guilty or innocent of a mock crime were interviewed. As predicted, deceptive statements were significantly more inconsistent with the evidence than truthful statements, and this was more pronounced as a function of late compared to early disclosure of evidence. In Experiment 2, adult observers (N = 168) made veracity assessments of the videotaped statements. Observers in the late disclosure condition achieved an accuracy rate higher than chance (63.1%), whereas accuracy rates in the early disclosure condition were at chance level (56%). Accuracy rates were significantly higher for truthful (70.2%), than deceptive statements (48.8%). Copyright © 2009 John Wiley & Sons, Ltd.     

The effects of social influence on children's memory reports: the omission and commission error asymmetry

Children in two age groups (7 vs. 12 yrs, N= 174) individually interacted with a stranger and were later interviewed about this event. Right before the interview, each child encountered the stranger once again and he engaged in a conversation where he either suggested that a (central or peripheral) detail originally present in the event had actually not been there or that an originally non-present (central or peripheral) detail had in fact been there. It was hypothesized that the two types of misinformation would result in omission and commission errors respectively. The results showed that the social influence resulted in an asymmetric effect (i.e., more commission than omission errors). Importantly, we also found that the children made more errors with respect to the peripheral detail (a suitcase), compared to the central detail (a passenger). Younger children did not make more errors (neither omission nor commission errors) than older children.     

Neural and genetic foundations of face recognition and prosopagnosia

Faces are of essential importance for human social life. They provide valuable information about the identity, expression, gaze, health, and age of a person. Recent face‐processing models assume highly interconnected neural structures between different temporal, occipital, and frontal brain areas with several feedback loops. A selective deficit in the visual learning and recognition of faces is known as prosopagnosia, which can be found both in acquired and congenital form. Recently, a hereditary sub‐type of congenital prosopagnosia with a very high prevalence rate of 2.5% has been identified. Recent research results show that hereditary prosopagnosia is a clearly circumscribed face‐processing deficit with a characteristic set of clinical symptoms. Comparing face processing of people of prosopagnosia with that of controls can help to develop a more conclusive and integrated model of face processing. Here, we provide a summary of the current state of face processing research. We also describe the different types of prosopagnosia and present the set of typical symptoms found in the hereditary type. Finally, we will discuss the implications for future face recognition research.     

Look what I have felt: unidentified haptic line drawings are identified after sketching

This study examined the influences of semantic characteristics of objects in real-world scenes on allocation of attention as reflected in eye movement measures. Stimuli consisted of full-color photographic scenes, and within each scene, the semantic salience of two target objects was manipulated while the objects' perceptual salience was kept constant. One of the target objects was either inconsistent or consistent with the scene category. In addition, the second target object was either smoking-related or neutral. Two groups of college students, namely current cigarette smokers (N=18) and non-smokers (N=19), viewed each scene for 10s while their eye movements were recorded. While both groups showed preferential allocation of attention to inconsistent objects, smokers also selectively attended to smoking-related objects. Theoretical implications of the results are discussed.     

Familiarity breeds distortion: the effects of media exposure on false reports concerning media coverage of the terrorist attacks in london on 7 July 2005

The present experiment investigated whether increased media exposure could lead to an increase in memory distortions regarding a traumatic public event: the explosion of the No. 30 bus in Tavistock Square, London on 7 July 2005. A total of 150 Swedish and 150 UK participants completed a series of questionnaires about their memory of either (i) the aftermath of the explosion, (ii) a non-existent computerised reconstruction of the moment of the explosion, or (iii) non-existent closed circuit television footage of the moment of the explosion. In line with the availability heuristic, U.K. participants were more likely than Swedish participants to claim to have seen all three types of footage. Furthermore, a subsample of U.K. participants who appeared to have developed false "memories" of seeing the No. 30 bus explode scored significantly higher on measures of dissociation and fantasy proneness than participants who did not develop false "memories". This experiment provides further support for the role of imaginative processes in the development of false memories.     

Gene Concepts and Genethics: Beyond Exceptionalism

The discursive explosion that was provoked by the new genetics could support the impression that the ethical and social problems posed by the new genetics are somehow exceptional in their very nature. According to this view we are faced with special ethical and social problems that create a challenge so fundamental that the special label of genethics is needless to justify. The historical account regarding the evolution of the gene concepts could serve us to highlight the limits of what we know about genes and what we can do with genes. The widespread notion about the exceptionality of genetic knowledge and its applicative possibilities is hardly justifiable and leads to misunderstandings regarding the conceptualization of the ethical and social problems we might face. Following a more realistic interpretation of the role of genes in human life we might avoid a whole set of fictive dilemmas and counterproductive regulatory efforts in bioethics. Bioethical discourse should move from the gene-centered scientific discourse toward the more sophisticated and complex discourses where human development represented as a matter of complex interactions between genomes and environments, between genes, educational factors, nutritional regimes, and other different developmental resources. If a gene is seen as one among the different developmental resources that are shaping a given human trait then both genethics and genetic exceptionalism could hardly be represented as a justified approach in discussing the ethical and social problems of genetics.     

Langzeitwirkungen psychoanalytischer und verhaltenstherapeutischer Langzeitpsychotherapien

The prospective study compares 31 patients in long-term behavior therapy with 31 patients in psychoanalytically oriented long-term therapy. A naturalistic design was applied within the German health system. All patients underwent a diagnostic interview (SCID) by an external interviewer. Only patients who fulfilled the DSM III-R criteria for a depression or an anxiety disorder were included in the study. Although the diagnoses of the patients undergoing long-term behaviour therapy and long-term psychoanalytical psychotherapy were comparable, we found that they differed in various ways. The differences arose in a number of characteristics, such as education, access to psychotherapy (recommended by professionals versus patients introducing themselves), usage of psychotropic medication, and the strain of symptoms. The average duration of long-term behavior therapy was 2.4 years and 64 sessions. The average duration of psychoanalytically oriented long-term therapy was 3.6 years and 209 sessions. Symptoms (SCL-90-R) and interpersonal problems (IIP) were examined at the beginning, after 1 year, 2.5 years, 3.5 years and after 7 years. Both groups showed significant degrees of improvement within the first 3.5 years and remained stabilized in the following 3.5 years regarding the symptomatic aspects. Focussing on the interpersonal problems, group PA showed further improvement after the 3.5-year period. The BT group however, showed no further improvement after 3.5 years but stabilized. The evaluated phase-model of psychotherapeutic change for short-term therapy was confirmed more clearly for long-term therapies of psychoanalytical orientation than for long-term therapies of behavioral orientation.     

The Leipzig episode in Freud's life (1859): a new narrative on the basis of recently discovered documents

This paper sheds new light on the facts and chronology of Sigmund Freud's two-month stay in Leipzig. Using material from the Leipzig city archives, the authors explore the attempts of Freud's father in 1859 to obtain a permanent residence permit in Leipzig for himself and his family. At that time, there was a ban on the immigration of foreign Jews into Saxony, lifted only for merchants whose residence was deemed beneficial to local commerce. Evidently, Jacob Freud did not meet this requirement and therefore had to move on to Vienna. The significance of these events for Freud's mental development is discussed.     

When and how communicated guilt affects contributions in public good dilemmas

Two laboratory studies investigated how groups may deal with the strong emotions that social dilemmas often elicit. A first study showed that a new group member evaluated guilt communicated by a fellow group member as more instrumental than neutral emotion feedback when the amount of required resources to obtain the public good (i.e., provision point) was perceived as difficult to obtain. A second study revealed that participants use communicated guilt to draw inferences about both past and future contributions from all fellow group members. Participants also contributed more themselves and adhered to equality more often when guilt versus no emotion was communicated, but only when the provision point was high. Expected contributions from fellow group members mediated this effect.
