Immediate spatial distortions of pointing movements induced by visual landmarks

We tested the influence of two horizontally aligned visual landmarks on pointing movements to memorized targets, to investigate whether the visuomotor system can make use of an egocentric representation unaffected by visual context. The endpoints of pointing movements were systematically distorted toward the nearest visual landmark, indicating that spatial representations included both target and nontarget information. These distortions were not due to the presence of the landmarks during the movement but, rather, to their presence in the encoding phase. Qualitatively similar distortions were present even with the shortest possible retention phase, when the target was extinguished at movement onset. Finally, we found the same pattern of distortion when participants were forced to remember the target within an allocentric frame of reference. We argue that even early memory representations for pointing movements are influenced by visual information in the surrounding visual field.     

Psychoanalytische Therapie

A statement of the professional umbrella society DGPT is presented that was formulated in cooperation with the various professional societies and with the German Society of Psychosomatic Medicine and Psychotherapy and the Society of Child and Adolescent Therapy. The statement is a reaction to the public claim for effective evidence of psychotherapy and takes the opportunity for a comprehensive presentation of this field. In the introduction Alf Gerlach, as chairman of the umbrella society at the time of the formulation of this statement and now executive chairman responsible for coordinating research, describes the history of the development of the statement.There were two particular moments prompting this statement. On the one hand the Scientific Advisory Board for Psychotherapy as an advisory committee based on the law of psychotherapy, has presented demands for effective evidence that are incompatible with psychoanalysis. Thus, the recognition of psychoanalysis as a treatment method for illnesses was put in doubt. On the other hand, a suggestion was put forward to the Board to recognize psychodynamic psychotherapy as an independent entity. This questioned the unity of the psychotherapeutic field.The statement was passed onto the Scientific Advisory Board last autumn. It is intended for a professional audience and includes answers to important issues of this field. It will have an important role to play in future discussions about professional politics. For this reason, we have decided to begin the present issue of our journal with this statement and thus to open a wide discussion forum.

Association of serotonin transporter promoter gene polymorphism with violence: relation with personality disorders, impulsivity, and childhood ADHD psychopathology

There is evidence that disturbances in central serotonin (5-HT) function have a role in impulsive aggression, violence, and criminality. A deletion/insertion polymorphism within the 5-HT transporter (5-HTT) promoter gene (5-HTT gene-linked polymorphic region, 5-HTTLPR) is thought to be associated with several psychopathological phenotypes related to disturbed impulse control, anxiety and depression. This study examined the association of the 5-HTTLPR with violent behavior in a sample of 153 male Caucasians referred for a forensic psychiatric examination. We found a significant excess of the short (s) allele and the s/s genotype in patients characterized by recurrent and overt physical violent behavior. This genetic variance explained 5% of the variance of violent behavior. When controlled for the impact of several psychopathologies related to violent behavior, this association was observed in individuals with a history of childhood attention deficit/hyperactivity disorder (ADHD)-related symptoms, but not presenting with personality disorder or increased impulsiveness. In conclusion, the results (i). suggest an association between serotonergic dysfunction and violent behavior, (ii). provide evidence for an-at least partial-genetic regulation of violent behavior in a subgroup of male offenders, and (iii). suggest a significant role for 5-HT transporter functionality for violent behavior.     

Quality of life assessment in Turkish patients with schizophrenia and their relatives

Quality of life of first-degree relatives living in the same household with patients having schizophrenia has not been sufficiently explored. 30 patients with schizophrenia (16 women, 14 men), diagnosed using DSM-IV criteria, 31 of their relatives (15 women, 16 men), and 34 control subjects (21 women, 13 men) were included in the study. The mean age of the patients, their relatives, and the control subects were 39.8 +/- 10.9, 58.1 +/- 12.5 and 37.3 +/- 17.0, respectively. The World Health Oranization Quality of Life-Brief Form was administered to all subjects. Quality of life was worse for the patient group than for their relatives and control subjects, but relatives of the patients and control subjects were not significantly different on Quality of life. Quality of life was negatively correlated with the severity of psychopathology and extrapyramidal side effects induced by antipsychotic drugs in the patients.     

What's in a (neutral) face? Personality disorders, attachment styles, and the appraisal of ambiguous social cues

Attachment theory suggests that borderline, avoidant, and schizoid personality disorders are differentially associated with anxious and avoidant attachment styles. The variations of insecure attachment in these disorders, in turn, might influence how others are perceived or appraised. To test these ideas, 176 college students completed questionnaires measuring attachment styles and personality disorder features, and each rated 10 emotionally neutral faces on 18 bipolar appraisal dimensions. As expected, borderline personality was associated with anxious attachment, avoidant personality was associated with anxious and avoidant attachment, and schizoid personality was weakly associated only with avoidant attachment. Furthermore, path analyses showed that borderline and avoidant personality features were associated with anxious attachment, which in turn related to negative face appraisals (e.g., tendencies to rate faces as less friendly and more rejecting). Discussion highlights the potential of simultaneously studying biases in social information processing and attachment disturbances among individuals with personality disorders.     

EMG activity as a function of the performer's focus of attention

In previous studies of attentional focus effects, investigators have measured performance outcome. Here, however, the authors used electromyography (EMG) to determine whether difference between external and internal foci would also be manifested at the neuromuscular level. In 2 experiments, participants (N=11, Experiment 1; N=12, Experiment 2) performed biceps curls while focusing on the movements of the curl bar (external focus) or on their arms (internal focus). In Experiment 1, movements were performed faster under external than under internal focus conditions. Also, integrated EMG (iEMG) activity was reduced when performers adopted an external focus. In Experiment 2, movement time was controlled through the use of a metronome, and iEMG activity was again reduced under external focus conditions. Those findings are in line with the constrained action hypothesis (G. Wulf, N. McNevin, & C. H. Shea, 2001), according to which an external focus promotes the use of more automatic control processes.     

Braking reaching movements: a test of the constant tau-dot strategy under different viewing conditions

Following F. Zaal and R. J. Bootsma (1995), the authors studied whether the decelerative phase of a reaching movement could be modeled as a constant tau-dot strategy resulting in a soft collision with the object. Specifically, they investigated whether that strategy is sustained over different viewing conditions. Participants (N = 11) were required to reach for 15- and 50-mm objects at 2 different distances under 3 conditions in which visual availability of the immediate environment and of the reaching hand were varied. Tau-dot estimates and goodness-of-fit were highly similar across the 3 conditions. Only within-participant variability of tau-dot estimates was increased when environmental cues were removed. That finding suggests that the motor system uses a tau-dot strategy involving the intermodal (i.e., visual, proprioceptive, or both) specification of information to regulate the decelerative phase of reaching under restricted viewing conditions. The authors provide recommendations for improving the derivation of tau;(x) estimates and stress the need for further research on how time-to-contact information is used in the regulation of the dynamics of actions such as reaching.     

Effects of age and anxiety on episodic memory: selectivity and variability

Selective age-related differences in source memory relative to item memory, and individual differences in memory performance in relation to anxiety were explored with high- and low-anxious subjects screened from normal young and elderly adults. They were read false facts about the locations of well-known and unknown sights in a male or female voice. Intentional and incidental learning instructions were administered for source memory. Selective age-related deficits in source memory were observed under both encoding conditions. Higher level of anxiety was related to lower memory performance only in the old group; this relation was stronger in source recall. The findings suggest that the presence of such selectivity is unrelated to the tradeoff between item encoding and source encoding. Anxiety affects the variability, and mediates the selectivity of age effects on episodic memory.     

The longitudinal and concurrent role of neuroticism for partner relationships

Neurotic characteristics of spouses have often been associated with dissatisfaction with the partner relationship. This article addresses the question whether the link between dissatisfaction with the relationship and neuroticism appears during the partner relationship, or whether it is present before the person enters the relationship. Utilizing data from a Swedish longitudinal project, satisfaction with the partner relationship was linked with neuroticism both in adolescence and in adulthood. Adolescent neuroticism was measured at age 15 with the High School Personality Questionnaire (HSPQ), and adult neuroticism was measured at age 37 with the Eysenck Personality Questionnaire (EPQ-I). Results showed that a lower degree of satisfaction in partner relationships in mid-life was linked with higher concurrent neuroticism scores. Opposing most of the previous studies, this association appeared for both men and women. Higher neuroticism in adolescence was, however, not significantly associated with satisfaction in partner relationships in mid-life.     

Psychological reactions in Icelandic earthquake survivors

The aim of this study was to explore the psychological consequences of two earthquakes in Iceland in two probability samples of subjects--residents in the exposed area and a control group from an unexposed area. The sample was composed of 52 adults exposed to the earthquakes and 29 adults in a control group. Three months after the earthquakes, both groups were approached with questions from a survey consisting of the Harvard Trauma Questionnaire (HTQ), the Trauma Symptom Checklist (TSC), the Coping Styles Questionnaire (CSQ), the World Assumption Scale (WAS), and the Crisis Support Scale (CSS). The results revealed that 24% in the exposed group had Posttraumatic Stress Disorder (PTSD), and none in the control group had PTSD. Earthquake-related anxiety, inability to express one's thoughts and feelings, and emotional coping predicted 81% of the HTQ variance for both groups. Previous life events, low self-worth, and luck attributions, together with numbing and the feeling of being let down, predicted 56% of the symptom variance for both groups. When degree of traumatization and emotional coping were added to the model, another 30% of the variance could be explained.
