Effects of repetitive stress during the acute phase of Trypanosoma cruzi infection on chronic Chagas' disease in rats

The effect of repetitive stress during acute infection with Trypanosoma cruzi (T. cruzi) on the chronic phase of ensuing Chagas' disease was the focus of this investigation. The aim of this study was to evaluate in Wistar rats the influence of repetitive stress during the acute phase of infection (7 days) with the Y strain of T. cruzi on the chronic phase of the infection (at 180 days). Exposure to ether vapor for 1 min twice a day was used as a stressor. Repetitive stress enhanced the number of circulating parasites and cardiac tissue disorganization, from a moderate to a severe diffuse mononuclear inflammatory process and the presence of amastigote burden in the cardiac fibers. Immunological parameters revealed that repetitive stress triggered a reduced concanavalin A induced splenocyte proliferation in vitro with major effects on the late chronic phase. Serum interleukin-12 concentration decreased in both stressed and infected rats in the early phase of infection although it was higher on 180 days post-infection. These results suggest that repetitive stress can markedly impair the host's immune system and enhance the pathological process during the chronic phase of Chagas' disease.     

Attention control and susceptibility to hypnosis

The present work aimed at assessing whether the interference exerted by task-irrelevant spatial information is comparable in high- and low-susceptible individuals and whether it may be eliminated by means of a specific posthypnotic suggestion. To this purpose high- and low-susceptible participants were tested using a Simon-like interference task after the administration of a suggestion aimed at preventing the processing of the irrelevant spatial information conveyed by the stimuli. The suggestion could be administered either in the absence or following a standard hypnotic induction. We showed that, outside from the hypnotic context, the Simon effect was similar in high and low-susceptible participants and it was significantly reduced following the posthypnotic suggestion in high-susceptible participants only. These results show that a specific posthypnotic suggestion can alter information processing in high-susceptible individuals and reduce the interfering effect exerted by arrow stimuli.     

Stroop effects on redemption and semantic effects on confession: simultaneous automatic activation of embedded and carrier words

The present study was aimed at assessing whether focusing attention on a task-relevant part of a word prevents processing of its meaning. Participants performed a color-naming task on a prime word followed by lexical decision on a probe. Primes were words, which could contain an embedded color word (e.g., “redemption”) written in an incongruent color. Probes were either semantically related (e.g., “confession”) or unrelated (e.g., “production”) to the prime word. A Stroop effect emerged for color words appearing either in the initial or in the final position of the carrier word. A priming effect also emerged, with faster responses to probes semantically related to the prime. These results are evidence that focusing attention on part of a prime (i.e., the embedded color word) does not prevent the semantic processing of the entire word.     

Virtual Reality Exposure in the Treatment of Panic Disorder With Agoraphobia: A Case Study

In this work we present a case example of the use of virtual reality exposure for the treatment of panic disorder with agoraphobia. The assessment protocol and procedure (including a baseline period) and the cognitive-behavioral treatment program are described. The clinical measures were categorized into target behaviors, panic and agoraphobia measures, global functioning, and general psychopathology measures. The patient’s expectations and satisfaction with regard to the virtual treatment were also assessed. The results showed an important reduction in all clinical measures after treatment with virtual exposure and the patient reached the therapeutic goals established during the pretreatment assessment. The patient also reported a good acceptance of virtual exposure. The goals achieved in the virtual environment generalized to real agoraphobic situations and to other real situations not treated. Three-, 6-, and 12-month follow-up assessments were conducted and long-term therapeutic gains were maintained.     

Validity of virtual reality as a method of exposure in the treatment of test anxiety

This is a validation study, aiming to explore the effectiveness of a set of virtual environments forproducing emotionally significant responses in students with high levels of test anxiety in order to be able to implement them later in treatment. Twenty-one students agreed to take part, 11 with high test anxiety and 10 with low test anxiety. The virtual environments were prepared in chronological order: the student's home, then the metro, and finally the corridor and lecture hall where the examination takes place. The results showed that the high-test-anxiety group presented higher levels of anxiety and depression than the low-test-anxiety group during exposure to the virtual environments. This study shows that virtual reality is able to provoke emotional responses in students with high test anxiety. This validation study should be followed up with treatment studies to evaluate the efficacy of virtual reality therapy for treating testanxiety.     

What causes the effect of age of acquisition in lexical processing?

Three hypotheses for effects of age of acquisition (AoA) in lexical processing are compared: the cumulative frequency hypothesis (frequency and AoA both influence the number of encounters with a word, which influences processing speed), the semantic hypothesis (early-acquired words are processed faster because they are more central in the semantic network), and the neural network model (early-acquired words are faster because they are acquired when a network has maximum plasticity). In a regression study of lexical decision (LD) and semantic categorization (SC) in Italian and Dutch, contrary to the cumulative frequency hypothesis, AoA coefficients were larger than frequency coefficients, and, contrary to the semantic hypothesis, the effect of AoA was not larger in SC than in LD. The neural network model was supported.     

A Survey of Challenges Experienced by New Learners Coding the Rorschach

Learning to code the imagery, communication, and behavior associated with Rorschach responding is challenging. Although there is some survey research on graduate students' impressions of their Rorschach training, research has not identified which coding decisions students find to be the most problematic and time-consuming. We surveyed students to identify what they struggled with most when learning coding and to quantify how difficult it is to learn how to code. Participants (n = 191) from the United States, Brazil, Denmark, Israel, and Italy rated 57 aspects of coding using a 4-point scale that encompassed both the time required to code and the subjective difficulty of doing so. Mean ratings for coding in general indicated that students considered the overall task challenging. Ratings also revealed that students struggled most with Cognitive Special Scores, Determinants, and extrapolating from the tables to code Form Quality for objects that were not specifically listed. The findings offer suggestions about how to improve the guidelines for some of the more difficult variables and where it is most necessary to focus teaching time. Taking these steps might help new students in learning the Rorschach.     

Relationship between inner dialog and ideas of reference and the mediating role of dissociation

Recent lines of research have begun to concentrate on internal dialogue and its relationship to a diversity of psychopathological phenomena present in psychotic disorders. This study was intended as a preliminary exploration of the relationship of internal dialogue, dissociation and ideas of reference. To do this, a sample of 318 students filled in an internal dialogue scale (the VISQ, McCarthy‐Jones & Fernyhough), one for dissociation (DES‐II, Carlson & Putnam) and another for ideas of reference (REF, Lenzenweger, Bennett & Lilenfeld). The results confirm the hypothesis posed in the sense that internal dialogue was positively associated with dissociation and with ideas of reference. A partial mediation effect of dissociation was also found between inner speech and ideas of reference. Lines of future research this study opens and its possible integration in a model on ideas of reference are discussed.

Occupational gender stereotypes and problem-solving in Italian adolescents

The first purpose of the study was to establish how Italian adolescents perceive jobs in the newly emerging economy sectors as well as more traditional jobs from gender-stereotyped and gender-segregated perspectives. The second purpose was to verify the role of problem-solving and gender in gender-role stereotyping. A total of 217 Italian high school students were involved. A questionnaire developed by Miller and Hayward was used to examine the students’ occupational gender-role stereotyping, segregation and interests. The Problem-Solving Inventory was administered to examine problem-solving. Adolescents perceived most jobs as being gender-stereotyped and -segregated. Female gender and problem-solving ability were associated with a reduced tendency to perceive jobs as gender-stereotyped.
