Lack of habituation to shocking words: The attentional bias to their spatial origin is context free

Following a suggestion made by Aquino and Arnell (2007), we assumed that the processing of emotional words is influenced by their context of presentation. Supporting this idea, previous studies using the emotional Stroop task in its visual or auditory variant revealed different results depending on the mixed versus blocked presentation of the stimuli (Bertels, Kolinsky, Pietrons, & Morais, 2011; Richards, French, Johnson, Naparstek, & Williams, 1992). In the present study, we investigated the impact of these presentation designs on the occurrence of spatial attentional biases in a modified version of the beep-probe task (Bertels, Kolinsky, & Morais, 2010). Attentional vigilance to taboo words as well as non-spatial slowing effects of these words were observed whatever the mixed or blocked design, whereas attentional vigilance to positive words was only observed in the mixed design. Together with the results from our previous study (Bertels et al., 2010), the present data support the reliability of the effects of shocking stimuli, while vigilance to positive words would only be observed in a threatening context.     

“Hidden Treasures” from Israeli Women's Writing Groups: Exploring an Integrative,Feminist Therapy

This article presents the work of mental health practitioners and laywomen who have developed and applied a new model of working with women in groups, a model founded on feminist principles that uses women's writing as the vehicle for group work. The model maintains a delicate balance between the needs of the group, the needs of the women in their social environment, and the women's ability to be the broker of their time, place, and mode of expression. This article presents the theoretical roots of the model and the qualitative evaluation of the writing groups that have been held over seven years, and it discusses how and why this model works for women of all ages and from all walks of life.     

False recollection of the role played by an actor in an event

Two experiments demonstrated that eyewitnesses more frequently associate an actor with the actions of another person when those two people had appeared together in the same event, rather than in different events. This greater likelihood of binding an actor with the actions of another person from the same event was associated with high-confidence recognition judgments and “remember” responses in a remember–know task, suggesting that viewing an actor together with the actions of another person led participants to falsely recollect having seen that actor perform those actions. An analysis of age differences provided evidence that familiarity also contributed to false recognition independently of a false-recollection mechanism. In particular, older adults were more likely than young adults to falsely recognize a novel conjunction of a familiar actor and action, regardless of whether that actor and action were from the same or from different events. Older adults’ elevated rate of false recognition was associated with intermediate confidence levels, suggesting that it stemmed from increased reliance on familiarity rather than from false recollection. The implications of these results are discussed for theories of conjunction errors in memory and of unconscious transference in eyewitness testimony.     

A comparison of human performance in figural and navigational versions of the traveling salesman problem

Performance on a typical pen-and-paper (figural) version of the Traveling Salesman Problem was compared to performance on a room-sized navigational version of the same task. Nine configurations were designed to examine the use of the nearest-neighbor (NN), cluster approach, and convex-hull strategies. Performance decreased with an increasing number of nodes internal to the hull, and improved when the NN strategy produced the optimal path. There was no overall difference in performance between figural and navigational task modalities. However, there was an interaction between modality and configuration, with evidence that participants relied more heavily on the NN strategy in the figural condition. Our results suggest that participants employed similar, but not identical, strategies when solving figural and navigational versions of the problem. Surprisingly, there was no evidence that participants favored global strategies in the figural version and local strategies in the navigational version.     

Symptoms,impairment and illness intrusiveness–their relationship with depression in women with CFS/ME

Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is an illness in which physiological and psychological factors are believed to interact to cause and maintain CFS/ME in an individual predisposed to it. The various symptoms and impairments associated with CFS/ME have a large impact on quality of life. The purpose of the present study was to identify the extent to which the core symptoms and impairments associated with CFS/ME relate to depression in women with CFS/ME, and to discover whether these relationships were mediated by illness intrusiveness. CFS/ME was found to be a highly intrusive illness, intruding into more life domains and to a greater degree than other illnesses. The effects of both symptoms and impairment on depression were, in part, mediated by illness intrusiveness. Although symptoms severity and impairment had both direct and indirect effects on depression, illness intrusiveness was the strongest predictor of depression.     

Sleep disturbance and emotion dysregulation as transdiagnostic processes in a comorbid sample

Sleep disturbance and emotion dysregulation have been identified as etiologic and maintaining factors for a range of psychopathology and separate literatures support their relationships to anxiety, depression, PTSD, and alcohol dependence (AD) symptom severity. Previous studies have examined these relationships in isolation, failing to account for the high rates of comorbidity among disorders. It is not yet known whether these processes uniquely predict symptom severity in each of these domains. Participants were 220 patients in residential substance abuse treatment, who had experienced a potentially traumatic event and exceeded screening cutoffs for probable PTSD and problematic alcohol use. Controlling for emotion dysregulation and the interrelationships among the outcome variables, insomnia was uniquely associated with anxiety (B = .27, p < .001), depression (B = .25, p < .001), PTSD (B = .22, p < .001), and AD (B = .17, p = .01) symptom severity. Similarly, controlling for insomnia, emotion dysregulation was uniquely associated with anxiety (B = .40, p < .001), depression (B = .47, p < .001), PTSD (B = .38, p < .001), and AD (B = .26, p < .001) symptom severity. Insomnia and emotion dysregulation appear to be transdiagnostic processes uniquely associated with symptom severity across a number of different domains and might be important treatment targets for individuals with PTSD and AD.     

A Foreigner in My Own Country: Forgetting the Heterogeneity of Our National Community

The issues of human cloning and stem cell retrieval are inseparable in circumstances in which the rationale of self-preservation may be invoked as a negative right. I apply this rationale to a hypothetical case in which cloning is necessary to preserve the bodily integrity or life of an individual. Self-preservation as moral integrity is examined in a narrower context, i.e., as applicable to those for whom deliberate termination of embryonic life is morally-problematic. This issue is addressed through comparison with two paradigms commonly used in support of clinical practice: the distinction between letting die and killing, and the permissibility of vital organ retrieval after death. Although these paradigms are questionable in their own right, they offer a rationale by which scientists and clinicians may respect the negative right to moral integrity of those with whom they disagree.     

Pupil diameter measurement errors as a function of gaze direction in corneal reflection eyetrackers

Pupil dilation is a useful, noninvasive technique for measuring the change in cognitive load. Since it is implicit and nonverbal, it is particularly useful with preverbal or nonverbal participants. In cognitive psychology, pupil dilation is most often measured by corneal reflection eye-tracking devices. The present study investigates the effect of gaze position on pupil size estimation by three common eye-tracking systems. The task consisted of a simple object pursuit situation, as a sphere rotated around the display screen. Systematic errors of pupil size estimation were found with all three systems. Implications for task-elicited pupillometry, especially for gaze-contingent studies such as object tracking or reading, are discussed.     

Long-Term stress reactions in new immigrants to israel exposed to the chernobyl accident

Abstract

This comparison study examined the relation between presumed level of exposure to the accident at Chernobyl in 1986 to symptoms of post-traumatic stress disorder (PTSD) and other psychological symptoms (depression, somatization, anxiety, obsessive-compulsive style and interpersonal sensitivity), life events and the negative appraisal of the events surrounding the accident. The sample (N = 708) included new immigrants from the former Soviet Union (Confederation of Independent States) who arrived in Israel since 1989 from more exposed areas (n = 137), less exposed (n = 240) and a comparison sample (n = 331) who immigrated from other republics. The exposed groups had higher mean scores on all psychological outcome measures than the comparison group, particularly symptoms of PTSD. Both subsequent stressful life events and a negative, cognitive assessment of events contributed to present psychological distress, independent of exposure.     

Strengthening encoding via implementation intention formation increases prospective memory commission errors

Prospective memory refers to the ability to remember to execute future intentions (e.g., taking medication with dinner). Although most prior research on prospective memory errors has focused on omission errors (i.e., failures to perform an intention in response to a target cue), there has been a recent surge in research on commission errors, the erroneous performance of a finished intention. Existing studies have examined factors at retrieval that lead to commission errors; the present study extends this research by investigating the impact of encoding strength. We found that relative to standard encoding, implementation intention encoding doubled the risk of commission errors in our laboratory paradigm for both young and older adults. This novel finding demonstrates the impact of encoding strength on commission errors and documents the potential challenges of deactivating the effects of implementation intentions upon completion of a prospective memory task.
