Frühkindlicher Autismus

Eine kurze Geschichte der Diagnose des frühkindlichen Autismus leitet diesen übersichtsartikelein. Die autistische St?rung zeichnet sich durch drei Hauptsymptomgruppen aus: St?rung der sozialen Interaktion, St?rung der Kommunikation, und stereotype, eingeschr?nkte Verhaltensmuster und Interessen. Aktuelle Kenntnisse im Bereich der ?tiopathogenese wurden kurz zusammengefasst. Diagnostische und differenzialdiagnostische Grundlagen werden diskutiert. Ein kurzer überblick der Pharmakotherapie des Autismus schlie?t die übersicht.     

Parenting of 7‐month‐old infants at familial risk for attention deficit/hyperactivity disorder

Patterns of interaction between parents and 7‐month‐old boys at familial risk for attention deficit/hyperactivity disorder (ADHD) and a comparison group were studied during a warm‐up and two play episodes. The sample included 78 (47 at‐risk, 31 comparison) mother–child and 45 (27 at‐risk, 18 comparison) father–child dyads. A coding system developed by G. Kochanska (1997, 1998) was used. Infants in the risk group did not differ from the comparison group in the rate of emission of infant‐related events. However, they received less adequate responsivity from both their fathers and their mothers to these events, and specifically to negative emotions or distress, than did the comparison group. Maternal psychopathology did not account for these findings. Mothers were more adequately responsive than were fathers, especially for physiological needs. The association between nonoptimal interaction in infancy and the development of ADHD is discussed.     

Testing Factorial Structure and Validity of the PCL:SV in Lithuanian Prison Population

This study examined the factorial structure and validity of the Hare Psychopathy Checklist: Screening Version (PCL:SV) in a European forensic context. A random sample of 257 criminal offenders from the Lithuanian prison population were administered the PCL:SV (Hart et al. 1995). The pattern of validity coefficients in this sample was comparable to other North American and non-North American samples. Several theoretical factorial structures for the PCL:SV were tested and compared. The two-factor model was not supported, while three- and four-factor models provided an acceptable fit to Lithuanian data. The four-factor model showed significantly better fit compared to the two-factor model. Correlations between PCL:SV factors and demographic variables confirm construct validity. However in the four-factor model, when controlling for correlations of the remaining three factors, only the Antisocial factor significantly correlated with variables related to criminal activity. It was concluded that the overall results of the PCL:SV in a male sample of Lithuanian offenders support cross-cultural generalizability of the construct of psychopathy as measured by the PCL:SV.     

Social learning modulates the lateralization of emotional valence

Although neuropsychological studies of lateralization of emotion have emphasized valence (positive vs. negative) or type (basic vs. complex) dimensions, the interaction between the two dimensions has yet to be elucidated. The purpose of the current study was to test the hypothesis that recognition of basic emotions is processed preferentially by the right prefrontal cortex (PFC), whereas recognition of complex social emotions is processed preferentially by the left PFC. Experiment 1 assessed the ability of healthy controls and patients with right and left PFC lesions to recognize basic and complex emotions. Experiment 2 modeled the patient’s data of Experiment 1 on healthy participants under lateralized displays of the emotional stimuli. Both experiments support the Type as well as the Valence Hypotheses. However, our findings indicate that the Valence Hypothesis holds for basic but less so for complex emotions. It is suggested that, since social learning overrules the basic preference of valence in the hemispheres, the processing of complex emotions in the hemispheres is less affected by valence.     

Perceived agency in retirement and retiree drinking behavior: Job satisfaction as a moderator

Based on recent findings that post-retirement adjustment may be influenced by the conditions leading up to the decision to retire, we examine the impact of individual agency in the retirement decision on problematic drinking behavior, as well as the extent to which such an effect may itself depend upon the valence of the pre-retirement work experience. Using a sample of 304 blue-collar retirees, our findings indicate that, when controlling for pre-retirement drinking behavior, perceptions of retirement as the result of a more forced or involuntary decision are associated with greater alcohol consumption, while perceptions of retirement as the result of a more volitional or voluntary process are associated with lower levels of alcohol consumption and a lower risk of problematic drinking behavior. Our results also indicate that pre-retirement job satisfaction amplifies the former relationship, while attenuating the latter one.     

Set recognition as a window to perceptual and cognitive processes

The Set visual perception game is a fertile research platform that allows investigation of perception, with gradual processing culminating in a momentary recognition stage, in a context that can be endlessly repeated with novel displays. Performance of the Set game task is a play-off between perceptual and conceptual processes. The task is to detect (among the 12 displayed cards) a 3-card set, defined as containing cards that are either all similar or all different along each of four dimensions with three possible values. We found preference and reduced response times (RTs) for perceiving set similarity (rather than span) and for including cards sharing the most abundant value in the display, suggesting that these are searched preferentially (perhaps by mutual enhancement). RT decreases with number of sets in the display according to a horse race model, implying independence of simultaneous searches. Central cards are included slightly more often, but set card proximity seems irrelevant. A supplementary experiment determining dimensional salience showed consistent but individual preferences, yet these seemed not to affect set identification. Training induced gradual improvement, which generalized to a new version of the game, suggesting high-level learning. We conclude that elements of perception such as similarity detection are basic for finding sets in this task, as in other real-world perceptual and cognitive tasks, suggesting the presence of basic similarity-perceiving mechanisms. The findings confirm the conclusion that conceptual processes are affected by perception.     

Well, slap my thigh: expression of surprise facilitates memory of surprising material

Two studies examined the general prediction that one's emotional expression should facilitate memory for material that matches the expression. The authors focused on specific facial expressions of surprise. In the first study, participants who were mimicking a surprised expression showed better recall for the surprising words and worse recall for neutral words, relative to those who were mimicking a neutral expression. Study 2 replicated the results of Study 1, showing that participants who mimicked a surprised expression recalled more words spoken in a surprising manner compared with those that sounded neutral or sad. Conversely, participants who mimicked sad facial expressions showed greater recall for sad than neutral or surprising words. The results provide evidence of the importance of matching the emotional valence of the recall content to the facial expression of the recaller during the memorization period.

Conflict, Identity, and Tolerance: Israel in the Al-Aqsa Intifada

This paper explores the impact of the Al-Aqsa Intifada on tolerance orientations of the Israeli Jewish public. We rely upon five surveys carried out between January 2000 and June 2002 to study in a real-life setting the amount and nature of change in political tolerance due to the conflict and the mechanisms behind it. Building on theory and research on intergroup relations in social psychology and political tolerance in political science, we focus upon threat and ingroup identification as the two primary factors in the social psychological processes resulting from conflict and leading to intolerance. We set the trends and explore mediation and interaction processes in the impact of this round of conflict on political tolerance.     

Between Israel and Germany from the “Alien Asiatic People” to the new German Jewry

How have Jews in Germany, stranded or returned there after World War II, related to Israel and to Germany, and how have their attitudes evolved since then? For decades, most Jews had no plans to stay in Germany, and their identification with and commitment to Israel, certainly in the first two decades, was extraordinary. However, over time their distance and even hostility to the German environment began to lessen, especially as West Germany developed ever closer ties with Israel. To a considerable degree, Germans themselves first reinitiated contacts with Jews and Jewish issues via Israel. In recent years, coinciding with the influx of Russian Jews and the policies of the Netanyahu and Sharon governments, there has been renewed emphasis on Diaspora and its values and a more positive reappraisal of the history of Jews in Germany. Nonetheless, basic ambivalences remain in place.     

Philosophy, the “unknown knowns,” and the public use of reason

There are not only true or false solutions, there are also false questions. The task of philosophy is not to provide answers or solutions, but to submit to critical analysis the questions themselves, to make us see how the very way we perceive a problem is an obstacle to its solution. This holds especially for today’s public debates on ecological threats, on lack of faith, on democracy and the “war on terror”, in which the “unknown knowns”, the silent presuppositions we are not aware of, determine our acts.
