Magnitude of relationship between burnout and absenteeism: a preliminary study

This study examined the influence of guilt related to a negative attitude toward patients and its relation with burnout and absenteeism. The sample consisted of 717 nursing professionals. Depersonalization was evaluated by the Maslach Burnout Inventory and Guilt was evaluated by one item. To estimate Absenteeism, participants were asked about the number of workdays they had missed in the past year. Hierarchical multiple regression analyses make it possible to conclude that guilt explains work absenteeism, and the interaction between depersonalization and guilt (Incr. R2 = .008, p < .05) indicates significant differences in the number of work days missed in the last year. Conclusions are limited, as these effects are quite weak: all variables together only explain about 4% of the shared variance in absenteeism. Researchers might assess whether feelings of guilt help explain the relationship between burnout and symptoms such as absenteeism.     

Trauma and memory: effects of post-event misinformation, retrieval order, and retention interval

The present study concerned effects of misinformation, retrieval order, and retention interval on eyewitness memory for a traumatic event (a vivid murder). Relations between misinformation acceptance and compliance were also examined. The classic three-stage misinformation paradigm (Loftus, 1979) was employed, with a multi-component recognition test added. Either immediately or 2 weeks after viewing a distressing film, 232 adults read a narrative (misleading or control) about the murder and then took a recognition test that tapped memory for central and peripheral details. Test-item order either matched the chronology of the film or was randomly determined. Significant misinformation effects were obtained. Moreover, control participants were more accurate in response to questions about central than peripheral information; however, this was not so for misinformed participants. Sequential but not random retrieval order resulted in a higher proportion of correct responses for central as opposed to peripheral misinformation questions. Compliance was significantly related to misinformation effects. Delay increased participants' suggestibility, impaired memory accuracy, and produced higher confidence ratings for misinformed participants compared to controls. Findings indicate that even for a highly negative event, adults' memory is not immune to inaccuracies and suggestive influences.     

Judgment of line orientation depends on gender, education, and type of error

Visuospatial tasks are particularly proficient at eliciting gender differences during neuropsychological performance. Here we tested the hypothesis that gender and education are related to different types of visuospatial errors on a task of line orientation that allowed the independent scoring of correct responses ("hits", or H) and one type of incorrect responses ("commission errors", or CE). We studied 343 volunteers of roughly comparable ages and with different levels of education. Education and gender were significantly associated with H scores, which were higher in men and in the groups with higher education. In contrast, the differences between men and women on CE depended on education. We concluded that (I) the ability to find the correct responses differs from the ability to avoid the wrong responses amidst an array of possible alternatives, and that (II) education interacts with gender to promote a stable performance on CE earlier in men than in women.     

Comparison of perceptual and motor latencies via anticipatory and reactive response times

To compare the timing of perceptual and motor decisions, distinct tasks have been designed, all of which have yielded systematic differences between these two moments. These observations have been taken as evidence of a sensorimotor dissociation. Inasmuch as the distinction between perceptual and motor decision moments is conceptually warranted, this conclusion remains debatable, since the observed differences may reflect the dissimilarity between the stimulations/tasks used to assess them. Here, we minimize such dissimilarities by comparing response time (RT) and anticipatory RT (ART), an alternative technique with which to infer the relative perceptual decision moments. Observers pressed a key either in synchrony with the third of a sequence of three stimuli appearing at a constant pace (ART) or in response to the onset of this third stimulus presented at a random interval after the second (RT). Hence, the two stimulation sequences were virtually identical. Both the mean and the variance of RT were affected by stimulus intensity about 1.5 times more than were the mean and the variance of ART. Within the framework of two simple integration-to-bound models, these findings are compatible with the hypothesis that perceptual and motor decisions operate on the same internal signal but are based on distinct criteria, with the perceptual criterion lower than the motor one.     

Photoelectric-helicoidal spirometer

This paper describes a photoelectric-helicoidal spirometer that has been designed in our laboratory. It includes a cylindrical helix (or turbine) partitioned in each of its blades by means of opaque plates transversally disposed. These plates obstruct the ray of light emitted by a diode, preventing it from reaching a photoreceptor located at the opposite side of the turbine. These basic elements are located in a module that can be adjusted to a mask that covers nostrils and mouth. Control software for this device is also described. The software facilitates a graphical representation of respiratory activity, as well as its storage in the computer. Software has been designed to be adaptable to any digital-to-analog converter. Both the device and the software have several advantages over traditional spirometers, as well as other nonspirometric techniques for studying respiratory activity.     

Short Form of the Social Anxiety Scale for Adolescents among community and institutionalized Portuguese youths

Background/Objective: Social anxiety is a common issue arising in adolescence that can cause significant impairment and have detrimental consequences for development in the absence of treatment. In this study we examined the factor structure and the psychometric properties of a 12-item short form of the Portuguese-Language Social Anxiety Scale for Adolescents (SAS-A-SF). Method: A community adolescent sample (N = 835) and a young offender sample (N = 244) completed the SAS-A, the Basic Empathy Scale and the Reactive-Proactive Aggression Questionnaire. Confirmatory factor analysis, internal consistency, cross gender and cross sample invariance, convergent and discriminant validity of the SAS-A-SF were analyzed. Results: The confirmatory factor analysis revealed that the 3-factor second-order model obtained the best fit.The results provided evidence that the SAS-A-SF is a psychometrically sound instrument that shows measurement invariance across genders and across samples, good reliability and positive correlations with empathy. Conclusions: The Portuguese version of SAS-A-SF is a useful, time-efficient tool for both researchers and practitioners who need to assess social anxiety, a relevant construct in adolescent psychopathology.     

Centrality ratings,forensic relevance,and production frequency: Which one best identifies central and peripheral items?

Production frequency has often been used to identify central and peripheral information, under the assumption that high frequency implies that the item is central. However, no research to date has tested the relationship between centrality and frequency. Participants watched a video of a bank robbery and completed a free recall test, from which frequency for recalled items was computed. Two groups then watched the same video and rated centrality and forensic relevance for each item. Results showed that most, but not all, items with high frequency were rated as central and forensically relevant but that low frequency items were not diagnostic of either item centrality or forensic relevance. Forensic relevance was a better indicator of item centrality than frequency. We concluded that frequency measures should be avoided to determine centrality. Also, if centrality ratings cannot be collected, forensic relevance ratings may be more appropriate for this purpose.     

The activation of representative emotional verbal contexts interacts with vertical spatial axis

Several experimental studies have shown that there exists an association between emotion words and the vertical spatial axis. However, the specific conditions under which this conceptual–physical interaction emerges are still unknown, and no study has been devised to test whether longer linguistic units than words can lead to a mapping of emotions on vertical space. In Experiment 1, Spanish and Colombian participants performed a representative verbal emotional contexts production task (RVEC task) requiring participants to produce RVEC for the emotions of joy, sadness, surprise, anger, fear, and disgust. The results showed gender and cultural differences regarding the average number of RVEC produced. The most representative contexts of joy and sadness obtained in Experiment 1 were used in Experiment 2 in a novel spatial–emotional congruency verification task (SECV task). After reading a sentence, the participants had to judge whether a probe word, displayed in either a high or low position on the screen, was congruent or incongruent with the previous sentence. The question was whether the emotion induced by the sentence could modulate the responses to the probes as a function of their position in a vertical axis by means of a metaphorical conceptual–spatial association. Overall, the results indicate that a mapping of emotions on vertical space can occur for linguistic units larger than words, but only when the task demands an explicit affective evaluation of the target.
