Procedural justice and status: status salience as antecedent of procedural fairness effects

The current article explores status as an antecedent of procedural fairness effects (the findings that perceived procedural fairness affects people's reactions, e.g., their relational judgments). On the basis of the literature, the authors proposed that salience of the general concept of status leads people to be more attentive to procedural fairness information and that, as a consequence, stronger procedural fairness effects should be found. In correspondence with this hypothesis, Experiment 1 showed stronger procedural fairness effects on people's relational treatment evaluations in a status salient condition compared with a control condition. Experiment 2 replicated this effect and, in further correspondence with the hypothesis, showed that status salience led to increased cognitive accessibility of fairness concerns. Implications for the psychology of procedural justice are discussed.     

Peritraumatic dissociation and posttraumatic stress after pregnancy loss: a prospective study

This study examined (1). predictors for peritraumatic dissociation, (2). its relations with acute and chronic symptoms of posttraumatic stress disorder (PTSD), and (3). pathways regarding these relations in response to pregnancy loss. In early pregnancy, about 1370 women volunteers completed questionnaires for neuroticism, control over emotions, dissociative tendencies, absorption, and prior life events. Of these, 126 subsequently experienced pregnancy loss and most of them completed measures 1 month (N = 118) and 4 months (N = 104) later. At 1 month, peritraumatic dissociation, memory of pregnancy loss (degree of fragmentation, sensory impressions, and emotional intensity), thought suppression, and PTSD symptoms were assessed, and at 4 months, PTSD symptoms were re-assessed. Peritraumatic dissociation was predicted by prior low control over emotions, dissociative tendencies, and lower education. It was not predicted by neuroticism, absorption, and prior life events. Peritraumatic dissociation was related to acute PTSD symptoms and LISREL analyses indicated that self-reported memory fragmentation and thought suppression of pregnancy loss mediated this relation. It also predicted chronic PTSD symptoms, and this relation was mediated by acute PTSD symptoms.     

Language localization in cases of left temporal lobe arachnoid cyst: evidence against interhemispheric reorganization

We investigated whether left-hemisphere arachnoid cysts lead to reorganization of the language function using PET. A group analysis demonstrated that patients showed no more right-hemisphere activation than a matched control group. Several patients had clear language localizations in the left hemisphere during language comprehension; none of the patients showed right-hemisphere activation. We conclude that left-hemisphere tissue must suffer considerable compromise before reorganization of language into the right hemisphere becomes necessary. Language activations within the left hemisphere are clearly displaced. This is consistent with mere physical displacement in some patients rather than reorganization within the left hemisphere; in others intrahemispheric reorganization cannot be excluded.     

Comprehension of televised stories in boys with attention deficit/hyperactivity disorder and nonreferred boys

Two studies compared comprehension of televised stories by 7- to 12-year-old boys with attention deficit/hyperactivity disorder (ADHD) and nonreferred comparison boys. Boys watched one show with toys present and one with toys absent. Visual attention was continuously recorded, and recall was tested after each show. Across studies, visual attention was high with toys absent but decreased sharply with toys present for boys with ADHD. Groups showed similar levels of cued recall of discrete units of information regardless of differences in attention. When recall tasks and television story structure required knowledge of relations among events, the reduced attention of boys with ADHD interfered with recall. Although visual attention of comparison boys also decreased to some extent with toys present, there was no such decrement in recall. Implications of the difficulties children with ADHD have in integrated story comprehension are discussed.     

A study of genetic and environmental effects on the co-occurrence of problem behaviors in three-year-old twins

The authors examined the genetic and environmental causes of the co-occurrence of problem behaviors in children. The analyses involved mother and father ratings of Oppositional, Withdrawn/Depressed, Aggressive, Anxious, Overactive, and Sleep Problems in 446 monozygotic and 912 dizygotic pairs of 3-year-old twins. Genetic factors contributed on average .150 (37.3%), shared environment .206 (51.2%), and nonshared environment .046 (11.4%) to the phenotypic correlations between the syndromes. Genetic and environmental factors caused different groupings. Internalizing and Externalizing groupings were indicative of nonshared environmental factors; clusters of problem behaviors with either the Aggressive or Anxious symptoms were most suggestive of genetic factors, and high scores on all syndromes indicated shared environmental influences.     

Resource Allocation by Greek and Dutch Students: A Test of Three Models

Three models are presented that explain cross-cultural differences in the allocation of resources to various social categories. (1) Individualism-collectivism predicts, for all kinds of resources, a higher allocation in collectivistic than in individualistic societies to members of one's in group. (2) Kagitçibasi's model of family change makes a distinction between material and nonmaterial resources. Collectivistic value patterns should lead to higher allocation of nonmaterial resources than found in individualistic societies, but no such difference is expected for material investments. Both these models assume cross-cultural differences in value orientations at a high level of generality. (3) An alternative is proposed, predicting universal patterns of exchange with only context-specific cross-cultural variations at a low level of generality. Hypotheses derived from the three models are tested with data from Greece and The Netherlands. It is concluded that the results are most compatible with the third model.     

Specificity of interoceptive fear to panic disorders

It has been argued that fear of interoceptive sensations is a maintaining factor in panic disorders. This study investigated whether interoceptive fears are specific to panic disorders or whether they are a feature of neurosis in general. Twenty-nine panic patients, 28 nonpanicking neurotic controls, and 29 normal controls were compared for their scores on a 14-item questionnaire intended to measure interoceptive fears. Indeed it was found that panic patients scored considerably higher than both control groups, whereas no significant differences emerged between the two control groups. It is concluded that interoceptive fear is diagnostically specific to panic disorders.This study was partly supported by the Dutch Organization for Fundamental Research (ZWO/Psychon., 560-268-001) and was carried out at the unit for clinical behavior therapy at Vijverdal Mental Hospital, Maastricht, The Netherlands.     

Electrodermal conditioning to stimuli of evolutionary significance: Failure to replicate the preparedness effect

In the present study, an attempt was made to replicate the preparedness effect reported by Öhman, Fredrickson, Hugdahl, & Rimmö (1976). Following Öhman et al. (1976) as closely as possible, a differential conditioning procedure was carried out in which subjects'skin conductance responses (SCRs) were conditioned either to stimuli of evolutionary significance (slides of snakes and spiders) or to evolutionally neutral stimuli (slides of mushrooms and flowers). The experiment consisted of 8 habituation, 12 acquisition, and 20 extinction trials. Electric shock served as an unconditioned stimulus during the acquisition phase. Although SCRs showed significant decreases during habituation and were significantly influenced by the conditioning procedure during acquisition, they were not found to extinguish significantly more slowly in the group that saw slides of snakes and spiders. This result contradicts the earlier results reported by Öman and colleagues. Possible explanations for this failure to replicate their results are discussed.     

Conditioning experiences and phobias

A retrospective study was conducted to examine the extent to which phobias are associated with a conditioning pathway to fear. The Phobic Origin Questionnaire (Öst and Hugdahl, Behav. Res. Ther. 19, 439–477, 1981) was administered to a sample of 91 phobic outpatients (patients with panic disorder with agoraphobia, social phobics, simple phobies). Results show clearly that conditioning experiences occur more frequently than either vicarious or informational, learning experiences, which confirms the findings previously reported by Rimm, Janda, Lancaster, Nahl and Dittmar (Behav. Res. Ther. 15, 231–238, 1977) and by Öst and Hugdahl (1981; Behav. Res. Ther. 21, 623–631, 1983). Yet, conditioning experiences consist mainly of panic attacks in confined environments. The findings also suggest that a considerable number of phobias are based on a combination of different pathways to fear.
