Validation studies of the Paranoia Checklist (Portuguese version) in mixed sample of patients and healthy controls

Introduction

Paranoid ideation has been consistently found as a phenomenon presented across the population continuum, and a theme that most people find in their everyday thoughts.

Predicting staff retention from employee motivation and job satisfaction

This study investigated the role of employee motivation and job satisfaction as predictors of staff retention in a foreign exchange bank. Participants were 341 employees of a South African foreign exchange bank division (female?=?62.8%; black?=?31.1%; managers?=?37%, mean years of experience?=?10 years). The employees completed the following self-report measures: Work Preference Inventory, Job Satisfaction Survey, and Employee Retention Questionnaire. Structural equation modelling was applied in the analysis to test the prediction effect of employee motivation and job satisfaction on staff retention. The findings of the model fit revealed that the model (employee motivation and employee job satisfaction) explained an estimated 46% of the variance in the employee retention construct. The job satisfaction construct in the model explained an estimated 66% of the variance in the employee retention construct; while the employee motivation construct explained only 8% of the variance. Organisational talent management should seek to identify employee motivation and job satisfaction interventions that might help to retain talented staff.     

PARADOXES AND STRUCTURAL RULES FROM A DIALOGICAL PERSPECTIVE

In recent years, substructural approaches to paradoxes have become quite popular. But whatever restrictions on structural rules we may want to enforce, it is highly desirable that such restrictions be accompanied by independent philosophical motivation, not directly related to paradoxes. Indeed, while these recent developments have shed new light on a number of issues pertaining to paradoxes, it seems that we now have even more open questions than before, in particular two very pressing ones: what (independent) motivations do we have (if any) for restrictions on structural rules, and what to make of the plurality of new logics emerging from these restrictions, i.e. how to ‘choose’ among the different options. In this paper, we address these two questions from the perspective of a dialogical conception of logic that we've been advocating in recent years. We will argue that dialogical interpretations of structural rules, that is, as rules determining specific properties of the dialogues in question, provide a conveniently neutral framework to adjudicate between the different substructural proposals that have been made in the literature on paradoxes.     

Portuguese Mothers and Fathers Share Similar Levels of Work-Family Guilt According to a Newly Validated Measure

Transformations in family and work life have led to profound changes in the articulation of both spheres. The massive entry of women into the labor market, the decline of a family model based on the male provider, increasing job demands, and persistent gender inequality are factors that can generate work-family conflict and lead to feelings of guilt. Work-family guilt is a topic still rarely studied, particularly in Portugal. Given the importance of understanding the complexity of the relationships underlying the work-family interface and the lack of instruments in Portuguese to assess the feeling of guilt as it pertains to the work-family interface, our goal was to adapt the Work-Family Guilt Scale (WFGS) to the Portuguese population. Our results confirmed the two-dimensional structure of the scale with good reliability and validity. The WFGS was invariant between genders, with no significant mean differences between men and women. Convergent validity with the variables of work-to-family and family-to-work conflict and discriminant validity between the two dimensions of the WFGS was demonstrated. Use of this scale will allow the identification of feelings of guilt, which pose risks to the physical, emotional and psychological well-being of workers. Guilt feelings should, like conflict, be considered as a psychosocial risk that must be mitigated through policies and practices aimed at promoting a balance between family and working life.     

Two Tales of Rumination and Burnout: Examining the Effects of Boredom and Overload

Although boredom poses serious consequences for employees and organizations, research has paid little attention to this phenomenon, especially when compared to other job experiences such as overload. Building upon the Effort-Recovery Model, our study examines the impact of these two sub-optimal experiences, characterized by under- and over-stimulation, on burnout via three facets of rumination. Using a time lagged design with three measurement moments and a sample of 152 participants, we found partial support for our hypotheses. Boredom and overload led to emotional exhaustion and disengagement 2 weeks later, via an increase in affective rumination. Overload also increased emotional exhaustion via reduced detachment, yet boredom reduced emotional exhaustion by facilitating detachment. These findings stress the importance of addressing boredom as a pervasive, although often silent, workplace phenomenon.     

Categorical perception of anger is disrupted in alexithymia: Evidence from a visual ERP study

High and low alexithymia scorers were confronted with a modified visual oddball task that allowed the study of categorical perception of emotional expressions on faces. Participants had to quickly detect a deviant (rare) morphed face that shared or did not share the same emotional expression as the frequent one. Expected categorical perception effects, which were also neurophysiologically indexed, showed that rare stimuli were detected faster if they depicted a different emotional expression compared to rare stimuli depicting the same emotional expression than the frequent one. Even if no differences were observed at a behavioural level, high alexithymia scorers evidenced overall delayed neurophysiological responses in components related to the attentional processing of rare emotional faces. Moreover, the categorical perception effects for event-related components associated with the attentional processing were smaller in high alexithymia scorers and were even absent for anger. These results show that high alexithymia scorers present discrimination delays that are already observed at the attentional level.     

Developmental dissociation of visual dorsal stream parvo and magnocellular representations and the functional impact of negative retinotopic BOLD responses

Localized neurodevelopmental defects provide an opportunity to study structure–function correlations in the human nervous system. This unique multimodal case report of epileptogenic dysplasia in the visual cortex allowed exploring visual function across distinct pathways in retinotopic regions and the dorsal stream, in relation to fMRI retinotopic mapping and spike triggered BOLD responses.     

Influence of wearing an unstable shoe construction on compensatory control of posture

This study investigated the influence of wearing unstable shoe construction (WUS) on compensatory postural adjustments (CPA) associated with external perturbations. Thirty-two subjects stood on a force platform resisting an anterior-posterior horizontal force applied to a pelvic belt via a cable, which was suddenly released. They stood under two conditions: barefoot and WUS. The electromyographic (EMG) activity of gastrocnemius medialis, tibialis anterior, rectus femoris, biceps femoris, rectus abdominis, and erector spinae muscles and the center of pressure (CoP) displacement were acquired to study CPA. The EMG signal was used to assess individual muscle activity and latency, antagonist co-activation and reciprocal activation at joint and muscle group levels. Compared to barefoot, WUS led to: (1) increased gastrocnemius medialis activity, (2) increased total agonist activity, (3) decreased antagonist co-activation at the ankle joint and muscle group levels, (4) increased reciprocal activation at the ankle joint and muscle group levels, and (5) decrease in all muscle latencies. No differences were observed in CoP displacement between conditions. These findings demonstrate that WUS led to a reorganization of the postural control system associated to improved performance of some components of postural control responses.     

Portuguese adaptation of the Gudjonsson Suggestibility Scales (GSS1 and GSS2): Empirical findings

In study 1 (n = 51, M_age = 21.4 years, SD = 5.7), the validity of the Portuguese adaptation of the Gudjonsson Suggestibility Scales ( Pires, 2011) was shown through the comparison of means of the original ( Gudjonsson, 1997) and the translated scales and the analysis of the correlations between the GSS1 and GSS2 scores. The relationships between interrogative suggestibility and the big five were also addressed and the results point to independence between suggestibility and personality, which is in line with Polczyk’s findings (2005). Study 2 (n = 87, M_age = 48.9 years, SD = 20.7) explored the relationships among interrogative suggestibility, the state–trait anxiety and demographic variables (i.e., age and gender). There were no significant relationships between anxiety and suggestibility. These results are in line with other studies that point to a lack of relationship between suggestibility and anxiety in normal samples (  and ). As for the relationships between age and interrogative suggestibility, ANCOVA confirmed that the increased suggestibility in old age was not due to age differences but rather to the limited memory capacity of the older adults group. There were no significant gender differences in the GSS1 subscales.     

Seeing green: Mere exposure to money triggers a business decision frame and unethical outcomes

Can mere exposure to money corrupt? In four studies, we examined the likelihood of unethical outcomes when the construct of money was activated through the use of priming techniques. The results of Study 1 demonstrated that individuals primed with money were more likely to demonstrate unethical intentions than those in the control group. In Study 2, we showed that participants primed with money were more likely to adopt a business decision frame. In Studies 3 and 4, we found that money cues triggered a business decision frame, which led to a greater likelihood of unethical intentions and behavior. Together, the results of these studies demonstrate that mere exposure to money can trigger unethical intentions and behavior and that decision frame mediates this effect.
