(Why) do I think what you think? Epistemic social tuning and implicit prejudice

This research examines whether people who experience epistemic motivation (i.e., a desire to acquire knowledge) came to have implicit attitudes consistent with the apparent beliefs of another person. People had lower implicit prejudice when they experienced epistemic motivation and interacted with a person who ostensibly held egalitarian beliefs (Experiments 1 and 2). Implicit prejudice was not affected when people did not experience epistemic motivation. Further evidence shows that this tuning of implicit attitudes occurs when beliefs are endorsed by another person, but not when they are brought to mind via means that do not imply that person's endorsement (Experiment 3). Results suggest that implicit attitudes of epistemically motivated people tune to the apparent beliefs of others to achieve shared reality.     

In times of uncertainty: predicting the survival of long-distance relationships

The authors examined the degree to which ratings of negative affectivity (NA) and relational security predicted the breakup of long-distance and same-city dating relationships. Couples completed initial surveys and were contacted 1 year later about the status of their relationship. In the initial surveys, both partners completed NA and relational security assessments. Overall, both the NA and relational security of men and women predicted stability. However, as predicted, structural equation modeling revealed a gender difference in the interaction between NA and long-distance status. The presence of high NA in men was associated with breakup for long-distance but not same-city couples. High NA in women was not differentially associated with relational stability on the basis of long-distance status. The authors discuss the psychological basis of this gender difference.     

Disturbed dreaming, posttraumatic stress disorder, and affect distress: a review and neurocognitive model

Nightmares are common, occurring weekly in 4%-10% of the population, and are associated with female gender, younger age, increased stress, psychopathology, and dispositional traits. Nightmare pathogenesis remains unexplained, as do differences between nontraumatic and posttraumatic nightmares (for those with or without posttraumatic stress disorder) and relations with waking functioning. No models adequately explain nightmares nor have they been reconciled with recent developments in cognitive neuroscience, fear acquisition, and emotional memory. The authors review the recent literature and propose a conceptual framework for understanding a spectrum of dysphoric dreaming. Central to this is the notion that variations in nightmare prevalence, frequency, severity, and psychopathological comorbidity reflect the influence of both affect load, a consequence of daily variations in emotional pressure, and affect distress, a disposition to experience events with distressing, highly reactive emotions. In a cross-state, multilevel model of dream function and nightmare production, the authors integrate findings on emotional memory structures and the brain correlates of emotion.     

Serotonin syndrome associated with the use of escitalopram

Escitalopram is the newest selective serotonin reuptake inhibitor (SSRI) available for use in the United States. It has been approved for the treatment of major depression and generalized anxiety disorder. It is the S-enantiomer of the SSRI citalopram and is highly serotonin specific as it has minimal effect on the reuptake of dopamine or norepinephrine. It is also a well-tolerated medication, with a side-effect profile comparable to the other SSRIs. While a number of side effects have been seen during escitalopram therapy, such as insomnia, nausea, and increased sweating, there are no reported cases of serotonin syndrome associated with escitalopram therapy to date. We present the case of a 24-year-old woman who developed serotonin syndrome after an increase in her escitalopram to 30 mg/day. We will review the diagnostic criteria of serotonin syndrome and the clinical scenarios in which serotonin syndrome can develop. We will also discuss the proposed treatments and role that polypharmacology may play in the development of this clinical entity.     

Alzheimer's disease patients' cognitive status and course years prior to symptom recognition

This is a prospective examination of the cognitive performance and cognitive course of persons in an asymptomatic "preclinical" phase who eventually developed Alzheimer's disease (AD). We compared performances on the Mayo Cognitive Factor Scales (MCFS) of 20 persons in a neurologically normal cohort who subsequently developed AD to the performances of 60 persons who remained free of dementia symptoms. For the AD patients, exams occurred prior to the appearance of dementia symptoms (an average of 4.2 and 1.5 years prior to symptom onset). Results reveal strong group differences on learning and retention, with eventual AD patients scoring lower than controls years prior to reporting symptoms of the disease. There was no significant interaction effect (group x testing session) for memory retention, suggesting that memory decline in this preclinical period may be too slow to be a useful indicator of future AD. A significant interaction (but no group effect) was seen for verbal comprehension.     

The costs of crossing paths and switching tasks between audition and vision

Switching from one functional or cognitive operation to another is thought to rely on executive/control processes. The efficacy of these processes may depend on the extent of overlap between neural circuitry mediating the different tasks; more effective task preparation (and by extension smaller switch costs) is achieved when this overlap is small. We investigated the performance costs associated with switching tasks and/or switching sensory modalities. Participants discriminated either the identity or spatial location of objects that were presented either visually or acoustically. Switch costs between tasks were significantly smaller when the sensory modality of the task switched versus when it repeated. This was the case irrespective of whether the pre-trial cue informed participants only of the upcoming task, but not sensory modality (Experiment 1) or whether the pre-trial cue was informative about both the upcoming task and sensory modality (Experiment 2). In addition, in both experiments switch costs between the senses were positively correlated when the sensory modality of the task repeated across trials and not when it switched. The collective evidence supports the independence of control processes mediating task switching and modality switching and also the hypothesis that switch costs reflect competitive interference between neural circuits.     

An Integrative Psychological Developmental Model of Supervision for Professional School Counselors‐in‐Training

Professional school counselors (PSCs) at higher levels of psychological development negotiate complex situations and perform counselor‐related tasks with empathy, flexibility, tolerance for ambiguity, boundary setting, personal and interpersonal awareness, and self‐care more effectively than do individuals at lower levels of development. This article introduces an integrative clinical supervision model designed to promote the psychological growth (ego maturity) of PSCs‐in‐training; presents practical components of the model; and discusses implications for PSC educators, supervisors, and researchers.     

Adult Attachment: Toward a Rapprochement of Methodological Cultures

ABSTRACT— Attachment security in adulthood is not profitably conceptualized as a single, monolithic construct. It is reflected both in adults' confidence in themselves and others in close relationships (as noted by social-personality psychologists) and in their ability to successfully construct a coherent life narrative about childhood experiences with primary attachment figures (as emphasized by developmental psychologists). Evidence suggests that measures tapping these forms of attachment-related variation represent the underlying structure of adult attachment similarly, in that both may be best captured by two continuously distributed, albeit correlated dimensions tapping anxiety and avoidance. Nonetheless, differing approaches to measuring adult security demonstrate weak empirical overlap, and emerging evidence suggests that each is associated with personal and interpersonal outcomes central to attachment theory in empirically distinct ways. Discussion focuses on how recent insights—in combination with needed experimental and longitudinal data—can help reconcile the developmental- and social-psychological literatures on adult attachment.     

Subjective frequency and imageability ratings for 3,600 French nouns

Subjective frequency and imageability estimates for a sample of 3,600 French nouns were collected from two independent groups of 72 young adults each. Both groups received standard instructions and provided their ratings on a 7-point scale. The timing, sequencing, presentation of lexical stimuli, and recording of responses were controlled by a computer. All estimates of internal consistency and test—retest reliability (≥.98) confirm the high level of precision and reliability of the ratings. Correlations with ratings drawn from similar studies were found to be positive and significant for subjective frequency (r ≥ .85) and for imageability (r ≥ .69). Subjective frequency was positively and significantly correlated with objective frequency estimates drawn from 10 different sources (r ≥ .42). Subjective frequency and imageability were significantly correlated (r=.26), a relationship that was driven primarily by a sudden drop in imageability ratings for words with a subjective frequency rating below 2.5. The methodological implications of these findings are discussed. The ratings can be downloaded as supplemental materials from brm.psychonomic-journals.org/content/supplemental.     

A computational technique for improving estimates of discriminability and bias across multiple dimensions of choice

Brown and White (2009) proposed measures of discriminability and bias that accommodate additional dimensions of choice—and hence, bias—in conditional discriminations such as matching-to-sample and the yes-no signal detection task. Their proposed measures increase the statistical independence of discriminability and bias estimates, thus improving their accuracy. Because Brown and White’s (2009) equations partition response data more than do standard equations, however, their measures have a slightly lower ceiling. Consequently, measurements can be less accurate when there are few trials and discriminability and bias are extreme. We introduce a computational estimation technique that overcomes this limitation. It estimates Brown and White’s (2009) discriminability and bias measurements from an array of related measures that have a higher ceiling. Simulations show that resulting estimates of discriminability and bias are either comparable to or more accurate than measurements calculated from traditional equations or Brown and White’s (2009) direct measures, even with few trials. A worked example of our technique may be downloaded from brm.psychonomic-journals.org/ content/supplemental.
