On the role of regular phonological variation in lexical access: evidence from voice assimilation in French

The present study investigated whether lexical access is affected by a regular phonological variation in connected speech: voice assimilation in French. Two associative priming experiments were conducted to determine whether strongly assimilated, potentially ambiguous word forms activate the conceptual representation of the underlying word. Would the ambiguous word form [sud] (either assimilated soute 'hold' or soude 'soda') facilitate "bagage" 'luggage', which is semantically related to soute but not to soude? In Experiment 1, words in either canonical or strongly assimilated form were presented as primes. Both forms primed their related target to the same extent. Potential lexical ambiguity did not modulate priming effects. In Experiment 2, the primes such as assimilated soute pronounced [sud] used in Experiment 1 were replaced with primes such as soude canonically pronounced [sud]. No semantic priming effect was obtained with these primes. Therefore, the effect observed for assimilated forms in Experiment 1 cannot be due to overall phonological proximity between canonical and assimilated forms. We propose that listeners must recover the intended words behind the assimilated forms through the exploitation of the remaining traces of the underlying form, however subtle these traces may be.     

Balancing concern for other with concern for self: links between unmitigated communion, communion, and psychological well-being

Previous research has demonstrated the importance of distinguishing between positive (communion) and negative (unmitigated communion) characteristics when investigating the relation between traditional feminine gender roles and psychological adjustment. However, previous work has relied on cross-sectional analysis of self-reported unmitigated communion and self-reported emotional distress. The present series of studies was designed to address this limitation by using multiple methodologies to examine the relation between unmitigated communion (UC) and psychological adjustment. Study 1 examined the relation between self- and peer reports in a sample of 102 college students. Study 2 examined the relation between communion, UC, and adjustment in a community sample of 94 adults using a 10-year longitudinal design. Study 3 used a daily diary methodology to examine the relation between these constructs, social functioning, and depressed mood in a sample of 78 college women. Results from the three studies converged to demonstrate that unmitigated communion is an important factor that impacts negatively on the psychological adjustment of men and women.     

Elevated content of cortisol in hair of patients with severe chronic pain: a novel biomarker for stress

Hair analysis has been used to reflect long-term systemic exposure to exogenous drugs and toxins. Several studies have demonstrated the feasibility of measuring endogenous steroid hormones, e.g. cortisol, in hair. Recently, a study in macaques showed a significant increase in hair cortisol levels induced by stress. We explored whether hair cortisol levels may be used as a biomarker for long-term stress in humans. Patients with severe chronic pain, aged 18 years or older, receiving opioid treatment for at least one year were recruited. Controls were non-obese (body mass index, BMI < 30 mg/kg(2)) adults. The Perceived Stress Scale (PSS) questionnaire was used to assess perceived stress over the last 4 weeks. A hair sample was obtained from the vertex posterior. Cortisol was measured using an enzyme-linked immunosorbent assay. We included fifteen patients (nine females and six males) and 39 non-obese control subjects (20 females, 19 males). PSS scores (median and range) were significantly higher in chronic pain patients (24: 12-28) than in controls (12: 3-31)(P < 0.001). Hair cortisol contents (median and range) were significantly greater in chronic pain patients (83.1: 33.0-205 g/mg) than in controls (46.1: 27.2-200 pg/mg) (P < 0.01). We conclude that hair cortisol contents are increased in patients with major chronic stress. Measurement of cortisol levels in hair constitutes a novel biomarker of prolonged stress.     

External validation of the computerized, group administrable adaptation of the “operation span task”

One of the most widely used tasks for measuring working memory capacity is the operation span task (OSPAN; Turner & Engle, 1989). This task has almost always been applied individually, and stimuli presentation is controlled by the experimenter. Recently, De Neys, d'Ydewalle, Schaeken, and Vos (2002) improved the administration procedure by designing an automated, group-administrable version of the task (GOSPAN). They found GOSPAN to be reliable, and they also provided evidence on its validity (a significant positive correlation between GOSPAN and OSPAN scores). However, an external test of GOSPAN validity is still lacking. In this work, we present such a validation for the automated version, when the task is administered both individually (Experiment 1) and to groups (Experiment 2). There are abundant previous data on the relation between working memory capacity and reading comprehension. In this work, this relation is studied using an automated OSPAN version to measure working memory capacity. Given that our results are similar to those found using the original OSPAN, our data support the external validity of the automated version of the task. We also tested the reliability of the task and found high internal consistency in both experiments.     

Physical and psychological aggression in dating relationships in Spanish university students

The presence of violent behaviors of a psychological and physical nature in dating relations was analyzed in a sample of Spanish university students between 18 and 27 years of age. The results indicate a high prevalence of both kinds of aggression in interpersonal relationships, revealing important typology differences between the sexes. Violent psychological behaviors (characterized by the presence of verbal aggression and coercive and jealous behaviors) and physical aggression were significantly higher in women, though the consequences of physical aggression were worse for the women's health. The implications of the results and their possible relation with more severe violent acts in more stable, emotional relationships are discussed.     

The job involvement modulating role in the relationship between stress and job satisfaction

This paper analyzes the modulator role of job involvement in the relationship between stress and job satisfaction, using the OSI (Occupational Stress Indicator) model. For this purpose, we analyzed: six sources of stress, the OSI job satisfaction results, and a job involvement scale. The sample consisted of 779 professional soldiers from the Spanish Army. The results show that when the levels of the two dimensions job involvement (psychological identification and job-related feelings of duty-obligation are high, stress due to achievements and career development and social relationships will have no influence on job satisfaction. However, we found higher job satisfaction, even when stress is high, in those situations where psychological identification is low and job-related feelings of duty-obligation are high.
