The Psychological Impact of Impending Forced Settler Disengagement in Gaza: Trauma and Posttraumatic Growth

The Israeli governments decision to remove settlers in the Gaza Strip forcibly produced a situation of traumatic stress, resulting from confrontation and conflict for settlers. The authors examined the effects of the Gaza disengagement, that occurred following prolonged terrorist exposure, on rates of probable major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) diagnosis in a representative sample of Gaza settlers (N = 190). Predictors of probable MDD in multivariate models were being female, and experiencing greater economic and psychosocial resource loss. Predictors of probable PTSD were being older and experiencing greater psychosocial resource loss. Posttraumatic growth was significantly related to a reduction in the odds of having probable PTSD. This latter finding is interpreted within our conceptualization of action-focused growth.

Preparing for Novel versus Familiar Events: Shifts in Global and Local Processing.

Six experiments examined whether novelty versus familiarity influences global versus local processing styles. Novelty and familiarity were manipulated by either framing a task as new versus familiar or by asking participants to reflect upon novel versus familiar events prior to the task (i.e., procedural priming). In Experiments 1-3, global perception was enhanced after novelty priming or framing, whereas familiarity priming facilitated local perception relative to a control group. In Experiment 4, participants used more inclusive categories under novelty priming and narrower categories under familiarity priming. In Experiments 5-6, participants construed actions and products more abstractly when these were framed as novel as compared to familiar. These results support the construal level theory (N. Liberman & Y. Trope, 2008; Y. Trope & N. Liberman, 2003) contention that having less direct experience is associated with using higher construal levels. Implications of the findings for research on mood, processing styles, stereotypes, and consumer research are discussed.

The Craving to Smoke in Flight Attendants: Relations With Smoking Deprivation, Anticipation of Smoking, and Actual Smoking

In the study, the authors examined the effects of smoking deprivation, anticipation of smoking, and actual smoking on the craving to smoke. Flight attendants who were light to heavy smokers rated their craving to smoke at predetermined time points during a 2-way short flight (each leg 3-5.5 hr) and a 1-way long flight (8-13 hr). In both short and long flights, craving increased gradually and peaked as landing approached. Craving levels at the end of the 1st leg of the short flights were equal to those at the end of the long flight and were much higher than those at the parallel time point in the long flight. In the short flight, craving levels at the beginning of the 2nd leg dropped relative to the end of the 1st leg, both for participants who smoked during the intermission and for those who did not, though the drop was steeper for the former. The results provide additional evidence for the role of psychological factors in determining the craving to smoke in a naturalistic setting.

An ironic effect of monitoring closeness

Most theories of goal pursuit underscore the beneficial consequences of monitoring progress towards goals. However, effects of affect labelling and dissociations between experience and meta-consciousness suggest that monitoring may not always facilitate goal pursuit. We predicted that in the case of pursuing interpersonal closeness, intense monitoring of progress would have a detrimental effect. We tested this hypothesis with the intimate conversation procedure, adapted from Aron, Melinat, Aron, Vallone, and Bator (1997). Participants in the closeness-monitoring condition asked themselves every five minutes in the course of a 45-minute interaction with a partner whether they felt any closer to their partner, whereas participants in the control condition monitored the room temperature. As predicted, intense monitoring interfered with achieving a feeling of closeness, as measured by sitting distance between pair members following the intimate conversation procedure. We discuss the possibility that monitoring would also be detrimental for achieving other goals that are internal states.

Show Me the Money: A Systematic Exploration of Manipulations, Moderators, and Mechanisms of Priming Effects

A major challenge for accumulating knowledge in psychology is the variation in methods and participant populations across studies in a single domain. We offer a systematic approach to addressing this challenge and implement it in the domain of money priming. In three preregistered experiments (N = 4,649), participants were exposed to one of a number of money manipulations before completing self-report measures of money activation (Study 1); engaging in a behavioral-persistence task (Study 3); completing self-report measures of subjective wealth, self-sufficiency, and communion-agency (Studies 1–3); and completing demographic questions (Studies 1–3). Four of the five manipulations we tested activated the concept of money, but, contrary to what we expected based on the preponderance of the published literature, no manipulation consistently affected any dependent measure. Moderation by sociodemographic characteristics was sparse and inconsistent across studies. We discuss implications for theories of money priming and explain how our approach can complement recent efforts to build a reproducible, cumulative psychological science.

Effects of Power on Mental Rotation and Emotion Recognition in Women

Based on construal-level theory (CLT) and its view of power as an instance of social distance, we predicted that high, relative to low power would enhance women’s mental-rotation performance and impede their emotion-recognition performance. The predicted effects of power emerged both when it was manipulated via a recall priming task (Study 1) and environmental cues (Studies 2 and 3). Studies 3 and 4 found evidence for mediation by construal level of the effect of power on emotion recognition but not on mental rotation. We discuss potential mediating mechanisms for these effects based on both the social distance/construal level and the approach/inhibition views of power. We also discuss implications for optimizing performance on mental rotation and emotion recognition in everyday life.

Proton pump inhibitors and the risk of severe cognitive impairment: The role of posttraumatic stress disorder

Proton pump inhibitors (PPIs), a common treatment for gastroesophageal reflux disease (GERD), were recently associated with increased risk of dementia. However, severe or chronic stress including, for example, posttraumatic stress disorder (PTSD) was not accounted for. This study examined whether PPI use was associated with severe cognitive impairment (SCI) and whether PTSD explained this association in a cohort of World Trade Center (WTC) responders.

Fatigue severity in World Trade Center (9/11) responders: a preliminary study

ABSTRACT Purpose: To assess fatigue severity in World Trade Center (9/11) responders 13 years later. Methods: The participant pool consisted of male 9/11 responders enrolled in the Stony Brook World Trade Center Health Program (WTC-HP), one of five centers of excellence established by the Centers for Disease Control and Prevention. Fatigue severity was assessed with the Fatigue Severity Scale. WTC-related medical conditions were certified by a physician and diagnoses of 9/11-related post-traumatic stress disorder (PTSD) and major depressive disorder (MDD) were determined with the Structured Clinical Interview for DSM-IV (SCID). Results: High fatigue severity was reported by 20.8% of the sample (N = 1079) and was significantly associated with PTSD, major depressive disorder, sleep apnea, gastro-esophageal reflux disease, upper respiratory disease, and lower respiratory disease. These associations remained significant for PTSD, major depressive disorder and lower respiratory disease when adjusted for medications, age and BMI. Only 17.3% of the high fatigue subgroup did not have an identified medical or psychiatric diagnosis. Fewer fatigued (21.1%) than non-fatigued (72.0%) responders rated their physical health as ‘good’ or ‘very good.’ Also fewer fatigued (33.9%) than non-fatigued (54.1%) responders were employed full-time (p < .0001). Conclusions: This study found clinically elevated fatigue in a high percentage of a male WTC responder cohort that prior to 9/11/2001 would be considered a ‘healthy worker cohort.’ To better understand the pathophysiology of fatigue, newer methodologies such as symptom provocation (e.g. exercise) designs may be useful.
