The role of subjective frequency in language switching: An ERP investigation using masked priming

Two experiments examined the nature of language-switching effects in a priming paradigm with event-related brain potential (ERP) recordings. primes and targets were always unrelated words but could be either from the same or different languages (Experiment 1) or from the same or a different frequency range (Experiment 2). Effects of switching language across prime and target differed as a function of the direction of the switch and prime duration in Experiment 1. Effects tended to be stronger with 100-ms prime durations than with 50-ms durations, and the expected pattern of greater negativity in the switch condition appeared earlier when primes were in L1 and targets in L2 than vice versa. Experiment 2 examined whether these language-switching effects could be due to differences in the subjective frequency of words in a bilingual’s two languages, by testing a frequency-switching manipulation within the L1. Effects of frequency switching were evident in the ERP waveforms, but the pattern did not resemble the language-switching effects, therefore suggesting that different mechanisms are at play.     

Stereopsis loses dominance over relative size as target separation increases

Binocular disparity produces less stereoscopic depth if the targets are separated by several degrees. It is thus possible that separation decreases the influence of stereopsis as a relative depth cue. Here, four experiments tested the strength of disparity in determining the direction of relative depth in the face of strongly conflicting relative size for a range of target separations. Under conditions of natural fixation-permitting sequential stereopsis-disparity dominated completely at small separations (0.42 degrees) but gradually gave way to relative size domination at large separations. However, when brief presentations prevented changes in fixation, disparity completely dominated at a separation of 0.5 degrees while relative size mostly dominated by 0.75 degrees - 1 degrees of separation. By varying target separation at different retinal eccentricities, we showed that separation per se was the critical factor in the dominance switch. Stereoacuity as a function of target separation for the same observers did not predict the switch from disparity to relative size. Stereoscopic dominance was found for the same small separations that are immune to stereoscopic reversals (Gillam, 1993 Perception 22 1025-1036). Our results suggest that relative disparity has a compulsory influence on perceived depth at small separations, suggesting a different mechanism from the one operating at larger separations.     

Psychologist suicide: Incidence, impact, and suggestions for prevention, intervention, and postvention

Psychologist practitioners are not immune to some mental health problems, including suicidality, for which they provide services. In the aftermath of two recent psychologist suicides, the American Psychological Association's Advisory Committee on Colleague Assistance (ACCA) initiated the formation of a conjoint ad hoc committee consisting of members from ACCA, the American Psychological Association (APA) Practice Directorate, and the Section on Clinical Emergencies and Crises (Section VII of APA's Division 12) to investigate the incidence of psychologist suicide and its impact on colleagues, students or interns, patients or clients, and the profession. The committee reviewed the extant empirical literature on suicide rates for psychologists, evaluated unpublished data on psychologist suicide provided by the National Institute of Occupational Safety and Health (NIOSH), interviewed colleague survivors, reviewed published case reports of the impact of therapist suicides, and linked their findings to the literature on professional distress, impairment, and self-care. The committee concluded that there is evidence suggestive of an elevated risk of suicide for psychologists in past decades. It further concluded that there is a need for further research to confirm if there is a heightened risk of suicide for psychologists in the present day, and to determine factors that might contribute to such risk. Accounts from colleague-survivors suggest that the impact of a psychologist's suicide can affect many people including family, colleagues, students, and patients or clients. This article offers suggestions for possible preventive approaches, for intervention with potentially at-risk colleagues, and for postvention efforts in the wake of a colleague suicide.     

The survey of personal beliefs: comparison of south african, mexican and american samples

In order to investigate the cross-cultural reliability and independence of subscales of the Survey of Personal Beliefs (SPB) data from 751 undergraduate Psychology students (189 White South African students, 114 Black South African students, 262 Mexican students and 186 American students) were compared. Coefficient alphas for the subscales in all samples were low, ranging from .33 to .76. However, alphas for the total scale across all subgroups were high. A comparison of the rank ordering of alpha coefficients for subscales in the different samples partially supported the cross-cultural reliability of the SPB for White South African and Mexican students, and for Black South African and American students. The similarities across samples regarding intercorrelations and shared variance between subscales also provided some evidence for the possible cross-cultural independence of subscales of the SPB. Comparison of total and mean subscale scores showed no significant differences between males and females within samples. However, a significant effect for culture, with significant between-subject effects for all the subscales as well as for the total score, was found. This may be indicative of real differences in irrational belief styles between the groups or may be a result of the insufficient cross-cultural reliability of the SPB.     

Insecure Attachment,Gender Roles,and Interpersonal Dependency in the Basque Country

Gender, gender role, and attachment style were used to predict emotional and instrumental dependency in a Basque student sample (N = 602). Psychometrically sound Spanish adaptations of English–language measures of dependency and attachment were created. As predicted, women were more emotionally and instrumentally dependent than men, but the sex differences were mediated by psychological masculinity and femininity. The anxious attachment dimension was correlated with emotional and instrumental dependency, the preoccupied rating with emotional dependency, and the avoidant attachment dimension and fearful rating with instrumental dependency. When the two attachment dimensions and the two gender–role variables were combined to predict dependency, emotional dependency was a function of anxious attachment and femininity; instrumental dependency was a function of anxious and avoidant attachment and low masculinity. Limitations and future directions are discussed.     

Activation of the attachment system in adulthood: threat-related primes increase the accessibility of mental representations of attachment figures

Three studies explored the effects of subliminal threat on the activation of representations of attachment figures. This accessibility was measured in a lexical decision task and a Stroop task following threat- or neutral-word primes, and was compared with the accessibility of representations of other close persons, known but not close persons, and unknown persons. Participants also reported on their attachment style. Threat primes led to increased accessibility of representations of attachment figures. This effect was specific to attachment figures and was replicated across tasks and experiments. Attachment anxiety heightened accessibility of representations of attachment figures even in neutral contexts, whereas attachment avoidance inhibited this activation when the threat prime was the word separation. These effects were not, explained by trait anxiety. The discussion focuses on the dynamics of attachment-system activation in adulthood.     

Interpersonal workplace stressors and well-being: a multi-wave study of employees with and without arthritis

The within-person influence of interpersonal stressors on affective well-being and physical well-being was investigated for 109 women with and without arthritis. Participants were interviewed on a weekly basis for 12 consecutive weeks, and the prospective data were analyzed by using hierarchical linear modeling. Overall, interpersonal workplace stressors independently predicted both well-being outcomes. Interpersonal stressors outside the workplace were related to negative affect but not to arthritis symptoms. Compared with healthy controls, arthritis patients' ratings of negative affect were equally reactive to workplace stressors. Neuroticism did not moderate stressor reactivity for either dependent variable but did predict mean levels of negative affect. The data support the hypothesis that the psychosocial environment of the workplace contributes unique effects on well-being.     

Attachment style and subjective motivations for sex

The relation of attachment style to subjective motivations for sex was investigated in an Internet survey of 1999 respondents. The relations of attachment anxiety and avoidance to overall sexual motivation and to the specific motives for emotional closeness, reassurance, self-esteem enhancement, stress reduction, partner manipulation, protection from partner's negative affect and behavior, power exertion, physical pleasure, nurturing one's partner, and procreation were explored. As predicted, attachment anxiety was positively related to overall sexual motivation and to all specific motives for sex, with the exception of physical pleasure. Avoidance was negatively related to emotional closeness and reassurance as goals of sex and positively related to manipulative use of sex but minimally related to most other motives. Sexual passion was positively related to attachment anxiety and negatively related to avoidance, and anxiety was related to the maintenance of passion over time, whereas avoidance was related to loss of passion over time.
