Moderator Role of Looming Cognitive Style (LCS) in the Relationship Between Attentional Control and Anxiety: Difference Between Shifting and Focusing Dimensions

Attentional control (AC) that is composed of shifting and focusing dimensions had been suggested as a transdiagnostic risk factor, associated with development and maintenance of various psychological disorders. In comparison, Looming Cognitive Style (LCS) had been documented as a trait-based, disorders-specific characteristic that is linked to high levels of subjectively felt anxiety. The present study investigated whether individual differences in LCS moderated the association of shifting and focusing with anxiety. Participants were 402 individuals between ages 18 and 68 recruited through advertisements posted on various forums, e-mail groups, and social media websites. They filled out questionnaires assessing AC, LCS, anxiety, and depression online. Results of the moderation analyses indicated that at high levels of LCS, low attentional shifting ability was associated with more intense anxiety. A similar relationship with LCS was not observed for focusing. In conclusion, for individuals who have high LCS and low shifting ability, content of and distress coming from looming images is experienced in a more intense manner due to difficulty in shifting to another (perhaps less anxiety provoking) content more flexibly. The findings are providing support for the interactive–synergistic perspective, indicating that deficits in shifting capacity may potentiate negative impact of looming cognitions.     

Cognitive control of a simple mental image in patients with obsessive--compulsive disorder

The nature of obsessions has led researchers to try to determine if the main problem in obsessive-compulsive disorder (OCD) is impaired inhibitory control. Previous studies report that the effort to suppress is one of the factors that increase the frequency of obsessive thoughts. Based on these results and those of the present study that suggest inferior parietal lobe (IPL) abnormality in OCD and findings of a recent study that reported the importance of the right posterior parietal cortex in cognitive control of a simple mental image, the present cognitive control paradigm study aimed to determine whether there is a difference in brain dynamics between OCD patients and non-obsessive controls while performing tasks that necessitate cognitive control of a simple mental image, and whether the right posterior parietal region is one of the regions in which a difference in activity between the OCD patients and controls would be observed. Functional brain imaging was performed while the participants attempted to suppress, imagine, or manipulate a mental image. The general linear model showed that there was a main effect of group and main effect of task. Accordingly, in all contrasts (suppression minus free-imagination, erasing minus free-imagination, and imagination minus free-imagination), the right IPL, right posterior cingulate cortex, and right superior frontal gyrus activity were lower in the OCD patients than in the healthy controls. These results and the observed correlations between activity levels, and symptom and subjective performance scores are discussed. In conclusion, the results of the present study and those of previous studies suggest that the main problem in OCD might be difficulty activating the right frontoparietal networks during tasks that require cognitive control, which might result in the intrusiveness of obsessive thoughts.     

A Systematic Review of the Effectiveness of Self-Compassion-Related Interventions for Individuals With Chronic Physical Health Conditions

Self-compassion, defined as a mindful way of coping with pain and suffering by showing kindness, care, and concern towards the self, may improve psychological adjustment in people living with a chronic physical health condition (CPHC). Various studies illustrate that self-compassion is associated with positive outcomes in general. The aim of this systematic review is to establish the effect of compassion-related therapies on self-compassion specifically in people with CPHCs. Secondary aims are to (a) establish the effect on other psychological and physiological outcomes and (b) explore the relative effectiveness of different therapy types among those identified. Cochrane, Embase, Medline, PsycINFO, and CINAHL databases were searched using “compassion” AND “chronic disease” AND “psychological outcomes” and their synonyms, from 2004 to March 2019. Eligible studies had an experimental design using a self-compassion scale with an adult population. Risk of bias (RoB) was assessed using the Cochrane RoB tool. Effect sizes were calculated for study outcomes. Fifteen studies, including a total of 1,190 participants, 7 different CPHCs, and 11 types of therapies, were included in the review. Nearly all included therapies significantly increased self-compassion with medium to large effect sizes, and reported positive outcomes, such as decreased depression. None of the therapy types appeared clearly superior to the others. Findings from this review show that included therapies increased self-compassion and improved various outcomes, which may represent clinically significant benefits for patients. However, there is a need to further understand how self-compassion exerts its benefits and determine the best methods to increase self-compassion.     

Interactive Effects of Looming Cognitive Style and Maladaptive Perfectionism on Trait Anxiety

Perfectionism is suggested as a transdiagnostic factor, related to development and maintenance of many psychological disorders. Looming Cognitive Style (LCS), on the other hand, is unique to anxiety disorders, acting as a specific a cognitive vulnerability for anxiety disorders. The present study aims to assess the association of anxiety with two cognitive vulnerability factors, LCS and maladaptive perfectionism. It was hypothesized that maladaptive perfectionism will have moderator role in the relationship between LCS and anxiety. A similar relationship is not expected for depression. Data were collected from 326 university students through self-report measures of LCS, perfectionism, anxiety, and depression. Results indicated the significant moderator roles of maladaptive perfectionism in the relationship of LCS with anxiety, even when the symptoms of depression are controlled. That is, maladaptive perfectionism was associated with higher levels of anxiety especially in individuals who had higher levels of looming vulnerability. A similar moderating effect of maladaptive perfectionism was not observed for depression. The results altogether emphasize the importance of examining the interactive effects of different vulnerability factors in understanding the mechanisms through which the risk factors operate.     

Age-related changes in odor discrimination

Odor naming and recognition memory are poorer in children than in adults. This study explored whether such differences might result from poorer discriminative ability. Experiment 1 used an oddity test of discrimination with familiar odors on 6-year-olds, 11-year-olds, and adults. Six-year-olds were significantly poorer at discrimination relative to 11-year-olds and adults, who did not differ. Experiment 2 used the same procedure but with hard-to-name visual stimuli and compared only 6-year-olds with adults (as with the remaining experiments in this study). There was no difference in performance between these groups. Experiment 3 used the same procedure as Experiment 1 but with less familiar odors. Six-year-olds were significantly poorer at discrimination than adults. In Experiment 4 the researchers controlled for verbal labeling by using an articulatory suppression task, with the same basic procedure as in Experiment 1. Six-year-old performance was the same as for Experiment 1 and significantly poorer than that of adults. Impoverished olfactory discrimination may underpin performance deficits previously observed in children. These all may result from their lesser experience with odors, relative to adults.     

Age-related changes in discrimination of unfamiliar odors

If odor perception involves mnemonic processes, differences in olfactory experience should affect discriminative ability. This was examined here by comparing discriminative performance in children and adults. Using an oddity test of discrimination, in Experiment 1 we tested 6-year-olds (G1), 11-year-olds (G6), and adults (A) on their ability to discriminate unfamiliar odors that varied either in quality (Q) or in quality and intensity (QI). G1 participants were poorer at discriminating the QI set, relative to G6 and A. In Experiment 2, we used an analogous visual procedure and confirmed that this age-related difference was olfactory specific. In Experiment 3, we repeated Experiment 1 but used an articulatory suppression task. G1 participants were poorer than G6 and A participants for both the Q and the QI sets. The implications of these findings for experiential accounts of odor perception and olfactory working memory are discussed.     

Parental Decisions Regarding a Prenatally Detected Fetal Chromosomal Abnormality and the Impact of Genetic Counseling: An Analysis of 38 Cases with Aneuploidy in Southeast Turkey

This study investigated parental decision-making to terminate or continue a pregnancy after prenatal diagnosis of a chromosomal abnormality among a sample of patients in Southeast Turkey. Between 2004 and 2007, 1068 amniocentesis tests were performed in the Medical Biology and Genetic Department Laboratory at Dicle University. Aneuploidy was found in 38 cases (3.56%). Genetic counseling was provided for the couples that received abnormal results, and they were later interviewed and asked if they had continued or interrupted the pregnancy after the diagnosis. When confronted with autosomal aneuploidy in which a severe prognosis was expected, 85% of cases decided to terminate the pregnancy. When confronted with sex chromosome aneuploidy with a low risk of an abnormal clinical phenotype 60% of cases decided to continue the pregnancy. Among the diagnoses with aneuploidy, pregnancy was continued in 21.1% of cases due to religious beliefs regardless of whether there was a low or severe risk of an abnormal clinical phenotype. These findings indicate that both severity of abnormality and religiosity play an important role in genetic counseling patients’ decision-making processes and outcomes in Turkey. In addition, the findings suggest the need for legislation that reduces the differences in approaches between the physicians and institutions regarding parental decision-making to terminate or continue a pregnancy in our country.     

The role of attention in the localization of odors to the mouth

Odors can be perceived as arising from the environment or as part of a flavor located in the mouth. One factor that may dictate where an odor is perceived to be is concurrent gustatory stimulation in the mouth. A taste may impair the ability to attend to an odor, especially if they are perceptually similar. Alternatively, salient mouth-based features of a flavor might command attention at the expense of smell. Experiment 1 and 2, using different stimulus sets, explored the impact of perceptually similar and dissimilar pairings of tastes in the mouth and odors at the nose. In each case, these were followed by judgments of the odor's location (mouth vs. nose). Perceptual similarity had no impact on localization judgments. Experiment 3 then manipulated the salience of the olfactory and gustatory cues and showed that each could independently shift the perceived location of an odorant-salient olfactory cues toward the nose and gustatory cues toward the mouth. These findings suggest that the salient features of a flavor may command attention at the expense of olfaction and, thereby, contribute to oral localization, with implications for flavor binding.     

Olfactory test performance and its relationship with the perceived location of odors

Odors are generally perceived as arising via the nose when sniffed and as part of an orally located flavor during ingestion. The perceived location of an odor may in part be an attentional phenomenon, with concurrent oral stimulation occurring at the expense of access to the olfactory channel. Two predictions were derived from this account: (a) tasks dependent on a capacity to attend to the olfactory channel--odor discrimination and naming--should be adversely affected by oral localization; and (b) tasks not dependent upon a capacity to attend--incidental learning/recognition memory--should not. Using a procedure to generate oral localization, in which odors were presented via the nose with concurrent oral stimulation (sucrose, a viscous fluid or water), greater reported oral localization was associated with poorer odor discrimination and naming, but not with recognition memory performance. These results support the notion that attentional processes contribute to oral localization of odors by reducing the capacity to attend to the olfactory channel.
