Prepartum and postpartum open-field behavior and maternal responsiveness in mice bidirectionally selected for open-field thigmotaxis

The authors examined pre- and postpartum open-field (OF) behavior and maternal responsiveness in mice that they bidirectionally selected for OF thigmotaxis. The authors tested 40 female mice under 3 conditions: prepartum OF, postpartum OF, and a pup retrieval test. In both OF conditions, the high OF thigmotaxis (HOFT) mice were more thigmotactic but explored and reared less than the low OF thigmotaxis (LOFT) mice, indicating that the HOFT mice were more emotional. In the postpartum condition, the HOFT mothers also defecated more and ambulated less than the LOFT mothers. The increase in grooming after parturition was more conspicuous among the LOFT mothers than among the HOFT mothers. The LOFT mothers were also more attracted to their pups in the OF, but the retrieval test did not show any substantial line differences. The results suggested that the line difference in emotionality was more pronounced during lactation than during pregnancy, although parturition exerted no effect on thigmotaxis.     

Sensory-specific satiety is intact in amnesics who eat multiple meals

What is the relationship between memory and appetite? We explored this question by examining preferences for recently consumed food in patients with amnesia. Although the patients were unable to remember having eaten, and were inclined to eat multiple meals, we found that sensory-specific satiety was intact in these patients. The data suggest that sensory-specific satiety can occur in the absence of explicit memory for having eaten and that impaired sensory-specific satiety does not underlie the phenomenon of multiple-meal eating in amnesia. Overeating in amnesia may be due to disruption of learned control by physiological aftereffects of a recent meal or to problems utilizing internal cues relating to nutritional state.     

Development of the Weight- and Body-Related Shame and Guilt scale (WEB-SG) in a nonclinical sample of obese individuals

In this article, we present the evaluation of the psychometric properties of a new self-report measure of Weight- and Body-Related Shame and Guilt (WEB-SG). The main purpose of the study was to measure shame and guilt feelings separately in obese individuals and investigate differing behavioral and emotional correlates of these emotions. Altogether, 331 obese participants completed the WEB-SG and other established self-report measures. A subset of the participants completed a 6-month follow-up. The WEB-SG proved to be internally consistent and temporally stable over a 6-month period. Regarding the factorial structure, a two-factor conceptualization was supported. The construct validity of the WEB-SG subscales was evidenced by a substantial overlap of common variance with related measures. The subscales Shame and Guilt showed differential correlation patterns to other scales. The WEB-SG is a brief, psychometrically sound measure for assessing body shame and guilt concerning weight control in obese individuals.     

Metacognitive therapy in recurrent depression: A case replication series in Denmark

Metacognitive therapy (MCT) for depression is derived from the Wells and Matthews (1994) self‐regulatory model, in which a Cognitive‐Attentional Syndrome (CAS) is the cause of psychological disorders. MCT for depression focuses on identifying patients' CAS and helps them to stop it. The CAS consists of worry, rumination and dysfunctional coping strategies. The focus in MCT is on removing the CAS by challenging positive and negative metacognitive beliefs and eliminating dysfunctional behaviors. In this case series, MCT was delivered to four depressed Danes and treatment was evaluated in 5–11 sessions of up to one hour each. An A‐B design with follow‐up at 3 and 6 months was conducted and the primary outcome was Beck's Depression Inventory II (BDI‐II). We measured CAS processes with the Major depressive Disorder Scale (MDD‐S). The results of the case series showed clinically significant improvements in depressive symptoms, rumination and metacognitive beliefs and the effects were still present at follow‐up for all patients. The small number of patients and decreasing baselines observed in some cases limits the conclusions. However, the results suggest that this treatment is feasible and was associated with large improvements in symptoms when delivered away from its point of origin and in a Danish help‐seeking sample.     

Cognitive functioning and cortisol profiles in first episode major depression

Major Depressive Disorder (MDD) is often associated with high levels of stress and disturbances in the Hypothalamic Pituitary Adrenal (HPA) system, yielding high levels of cortisol, in addition to cognitive dysfunction. Previous studies have shown a relationship between cortisol profile and cognitive functioning in recurrent MDD in general. More specifically, the association between hypercortisolism and cognitive functioning, such as memory and Executive Functioning (EF), and also more recently cortisol suppression has been explored. However, no studies have investigated these relationships in patients diagnosed with first episode MDD. The aim of the present study was to examine the relationship between cortisol levels before and after the Dexamethasone suppression test (DST) and cognitive function in first episode MDD patients. Twenty‐one patients meeting the DSM‐IV criteria for a first episode of MDD diagnosis were included in the study. The control group was matched for age, gender and education level. Cortisol was measured in saliva collected with Salivette sampling devices. Saliva samples were collected 4 times during a 24 hours period over two consecutive days: at awakening, after 45 minutes, after 7 hours and at 11 pm. Dexamethasone (1.0 mg) was given orally on Day 1 at 11 pm. The neuropsychological test battery consisted of standardized tests measuring executive functioning (EF) and memory functioning. Cortisol levels did not differ significantly between patients and controls on Day 1, except for the last sample before Dexamethasone administration, where the control group showed higher levels. Both groups showed suppression after Dexamethasone. On Day 2 there was a significant difference between groups at the third sample, showing a significantly lower level in the control group, suggesting that the controls have a more effective suppression profile than the patients. There were no significant correlations between cortisol levels before or after Dexamethasone and cognitive measures. The results indicate impairment on HPA‐axis functioning in first episode MDD patients, with less suppression functioning compared to healthy controls, but no relationship between cortisol profile and cognitive functioning in EF or Memory.     

Illness Perception and Well-Being Among Persons with Multiple Sclerosis and Their Caregivers

This study jointly examined illness beliefs held by persons with multiple sclerosis (PwMS) and caregivers in relation to well-being. A group of 68 PwMS and their caregivers completed the Revised Illness Perception Questionnaire, Psychological Well-being Scales, Satisfaction with Life Scale and Positive Affect and Negative Affect Schedule. Findings revealed that PwMS’ well-being was primarily predicted by their own illness beliefs, and that also caregivers’ well-being was primarily predicted by their own beliefs. Across the two groups, well-being was positively associated with their belief that they understood the disease, and inversely associated with their representations of negative emotions. In addition, among PwMS, well-being was inversely associated with the number of symptoms they specifically attributed to their illness, while among caregivers, well-being was positively associated with beliefs that treatment could control the disease. Based on the study findings, psychoeducational and cognitive-behavioral strategies are suggested to promote well-being among PwMS and caregivers.     

Socialisation Influences on Gender Ideologies of Immigrant and Native Youth in Germany,England, Sweden and the Netherlands

Adolescence is a crucial life course phase for identity formation, and youths’ gender ideologies significantly predict gendered behaviours and longer-term transitions. With Western post-industrial societies becoming more culturally diverse, the present study provides novel cross-nationally comparative evidence on gender socialisation processes among native and immigrant youth in Sweden, Germany, England, and the Netherlands, which vary in gender and migration policies and cultures. In addition to parents’ gender ideologies, the study also considers classmates’ gender ideologies as factors shaping 14-year-old adolescents’ gender ideologies. The analysis draws on 5917 adolescent-parent dyads from the Children of Immigrants Longitudinal Study which we link with country-level gender empowerment measures from the United Nations. Remarkably, with the exception of native female adolescents in England and Germany, parents tend to report slightly more egalitarian beliefs than adolescents across the four countries. OLS regressions show that parents’ and classmates’ gender ideologies correlate significantly with adolescents’ ideologies, with little variation across gender and immigrant groups in all four countries. From a policy and practical point of view, the great similarity in the intergenerational transmission of gender beliefs across diverse family backgrounds as well as cultural and policy contexts seem remarkable.

     

Investigating the Links Between Cultural Values and Belief in Conspiracy Theories: The Key Roles of Collectivism and Masculinity

Research suggests that belief in conspiracy theories (CT) stems from basic psychological mechanisms and is linked to other belief systems (e.g., religious beliefs). While previous research has extensively examined individual and contextual variables associated with CT beliefs, it has not yet investigated the role of culture. In the current research, we tested, based on a situated cultural cognition perspective, the extent to which culture predicts CT beliefs. Using Hofstede's model of cultural values, three nation-level analyses of data from 25, 19, and 18 countries using different measures of CT beliefs (Study 1, N = 5323; Study 2a, N = 12,255; Study 2b, N = 30,994) revealed positive associations between masculinity, collectivism, and CT beliefs. A cross-sectional study among U.S. citizens (Study 3, N = 350), using individual-level measures of Hofstede's values, replicated these findings. A meta-analysis of correlations across studies corroborated the presence of positive links between CT beliefs, collectivism, r = .31, 95% CI = [.15; .47], and masculinity, r = .39, 95% CI = [.18; .59]. Our results suggest that in addition to individual differences and contextual variables, cultural factors also play an important role in shaping CT beliefs.     

Attention and semantic processing during speech: an fMRI study

This fMRI study was conducted to investigate whether language semantics is processed even when attention is not explicitly directed to word meanings. In the “unattended” condition, the subjects performed a visual detection task while hearing semantically related and unrelated word pairs. In the “phoneme” condition, the subjects made phoneme judgements between prime and target words, and in the “word” condition, they indicated whether the words in each word pair were semantically related or unrelated. In the word condition, stronger activity was obtained for unrelated than related words in the superior temporal gyrus/sulcus (STG/STS), lingual/fusiform gyri and cuneus, whereas in the phoneme condition no such effect was observed. However, during the unattended condition, stronger activity was found in the right STG. Our results suggest that both semantic judgement of word pairs and their passive hearing activate the same neural networks but this activation is more restricted in the passive hearing.
