Cognitive Fusion Questionnaire—Body Image: Psychometric Properties and Its Incremental Power in the Prediction of Binge Eating Severity

Given the clinical usefulness of the CFQ-BI (Cognitive Fusion Questionnaire—Body Image; the only existing measure to assess the body-image-related cognitive fusion), the present study aimed to confirm its one-factor structure, to verify its measurement invariance between clinical and non-clinical samples, to analyze its internal consistency and sensitivity to detect differences between samples, as well as to explore the incremental and convergent validities of the CFQ-BI scores in Brazilian samples. This was a cross-sectional study, which was conducted in clinical (women with overweight or obesity in treatment for weight loss) and non-clinical samples (women from the general population). The one-factor structure was confirmed showing factorial measurement invariance across clinical and non-clinical samples. The CFQ-BI scores presented an excellent internal consistency, were able to discriminate clinical and non-clinical samples, and were positively associated with binge eating severity, general cognitive fusion, and psychological inflexibility. Furthermore, body-image-related cognitive fusion scores (CFQ-BI) presented incremental validity over a general measure of cognitive fusion in the prediction of binge eating symptoms. This study demonstrated that CFQ-BI is a short scale with reliable and robust scores in Brazilian samples, presenting incremental and convergent validities, measurement invariance, and sensitivity to detect differences between clinical and non-clinical groups of women, enabling comparative studies between them.     

Gender differences in reaction to psychological pressure: evidence from tennis players

Using data on about 35,000 professional tennis matches, we test whether men and women react differently to psychological pressure arising from the outcomes of sequential stages in a competition. We show that, with respect to men, women losing the first set are much more likely to play poorly the second set. This suggests that women are more discouraged when facing the pressure of falling behind and receiving negative feedback. The gender differential is stronger in high-stake matches. On the other hand, when players are tied in the third set we do not find any gender difference in players’ reactions suggesting that women are as able as men to handle pressure if they do not lag behind. These results are robust controlling for measures of abilities and fitness of players, such as players’ rankings, players’ ex-ante winning probability, players’ rest, monetary prizes, players’ and tournaments’ fixed effects.     

On the control of visual spatial attention: evidence from human electrophysiology

We used electrophysiological methods to track the deployment of visual spatial attention while observers were engaged in concurrent central attentional processing, using a variant of the attentional blink paradigm. Two visual targets (T₁, T₂) were presented at a stimulus onset asynchrony of either 200 ms or 800 ms. T₁ was a white digit among white letters presented on a dark background using rapid serial visual presentation at fixation. T₂ was another digit that was presented to the left or right of fixation simultaneously with a distractor digit in the opposite visual field, each followed by a pattern mask. In each T₂ display, one digit was red and one was green. Half of the subjects reported the red digit and ignored the green one, whereas the other half reported the green digit and ignored the red one. T₁ and T₂ were reported in one block of trials, and only T₂ in another block (order counterbalanced across subjects). Accuracy of report of T₂ was lower at short SOA than at long SOA when both T₁ and T₂ were reported, but was similar across SOA when only T₂ was reported. The electrophysiological results focused on the N2pc component, which was used as an index of the locus of spatial attention. N2pc was reduced in amplitude when subjects reported T₁, and particularly so at the short SOA. The results suggest that attention to T₁ interfered with the deployment of visual spatial attention to T₂.     

When "macrocefalo (macrocephalous)" is read "minicervello (minibrain)": evidence from a single case study

We report the case of a patient who showed a marked deficit in compound reading after almost complete recovery from his aphasic disturbances. Omission of one of the two compound components was his most frequent type of error. The patient also produced many paraphasias, which always respected the compound structure of the target. Similar errors were found on tasks of naming and writing to dictation. A deficit in retrieving the verb component of verb-noun compounds was also observed, consistent with the patient's residual agrammatism, and with decomposition at some point in processing. We suggest that this pattern of performance is compatible with a dual route model that hypothesises two stages of compound retrieval, a whole word stage followed by a decomposition into two constituent morphemes.     

Cognitive changes following subthalamic nucleus stimulation in two patients with Parkinson disease

The limits of a drug therapy in severe forms of Parkinson disease have led to refining neurosurgery on the basal ganglia. Deep brain stimulation of the subthalamic nucleus has been recognized as one of the most promising techniques to decrease "off" motor symptoms and motor fluctuations, allowing a reduction of drug therapy and limiting side effects of the drugs. There is still open debate on the possible consequences of chronic subthalamic stimulation in other ways, apart from motor symptoms, of general cognitive performance. We examined and followed two patients with Parkinson disease for 9 mo. after surgery for deep stimulation, studying their cognitive performances. There is a general amelioration of cognitive performances, in particular as far as linguistic capabilities is concerned. We discuss the possible significance of these results, reminding strenuously that only two patients were involved, so the potential for generalization is seriously limited.     

The indirect effect of cognitive reserve on the relationship between age and cognition in pathological ageing: A cross-sectional retrospective study in an unselected and consecutively enrolled sample

Cognitive reserve (CR) allows individuals to maintain cognitive functionality even in the presence of pathologies. The compensation hypothesis suggests that CR plays an indirect role between age and cognitive decline, contrasting the negative effect of ageing on cognition. We test this hypothesis in an unselected and consecutively enrolled sample of memory clinic attendees (n = 134) who completed the CR Index questionnaire and three neuropsychological tests assessing global cognition (MMSE, FAB, CDT). Participants were divided into two groups based on standard diagnostic criteria (DSM-5): those who were cognitively impaired (n = 92) and those who were preserved (n = 42). A principal component analysis was used to extract a composite measure of global cognitive functioning from the three neuropsychological tests, and mediation analysis was used to examine the relationship between CR, age and global cognitive functioning in the two groups. Results revealed that: (i) age had a significant direct negative effect on the global cognitive score in both groups; (ii) the three socio-behavioural proxies of CR together suppress the direct negative relationship between age and global cognitive score in cognitively impaired patients but not in cognitively preserved participants. This study confirms the association between CR, age and cognition and allows us to validate its role in a population with cognitive impairment and extend findings to a low-to-middle educated population. These results hold important implications for public health and wellness promotion, emphasising the beneficial role of maintaining healthy and active physical, cognitive and social lifestyles.     

Cross‐Situational Learning of Minimal Word Pairs

Cross‐situational statistical learning of words involves tracking co‐occurrences of auditory words and objects across time to infer word‐referent mappings. Previous research has demonstrated that learners can infer referents across sets of very phonologically distinct words (e.g., WUG, DAX), but it remains unknown whether learners can encode fine phonological differences during cross‐situational statistical learning. This study examined learners’ cross‐situational statistical learning of minimal pairs that differed on one consonant segment (e.g., BON–TON), minimal pairs that differed on one vowel segment (e.g., DEET–DIT), and non‐minimal pairs that differed on two or three segments (e.g., BON–DEET). Learners performed above chance for all pairs, but performed worse on vowel minimal pairs than on consonant minimal pairs or non‐minimal pairs. These findings demonstrate that learners can encode fine phonetic detail while tracking word‐referent co‐occurrence probabilities, but they suggest that phonological encoding may be weaker for vowels than for consonants.     

Influences of Fertility Status on Risky Driving Behaviour

The effects of hormones on human behaviour have been extensively studied, but little attention has been paid to the influence of ovarian hormones on risky driving. Twenty‐five normally cycling women took part in three sessions, including an ovulatory phase estimation session and two experimental sessions: high vs low fertile phases. These two phases were monitored through a urine‐based luteinizing hormone predictor test. In the two experimental sessions, participants were administered the Driving Behaviour Questionnaire and the Vienna Risk‐Taking Test. Results showed that women are more risk‐averse in their driving behaviour during their high‐fertile phase. The influence of hormonal fluctuations on self‐perception of risk attitude when driving was non‐significant. Findings are discussed from an evolutionary perspective.

When working memory updating requires updating: Analysis of serial position in a running memory task

This study aimed to investigate updating in working memory (WM), analyzing the effects of task demand and memory resources on serial position curve (SPC), in a running memory task with slow pace presentation and a probed recognition procedure. These task conditions were supposed to produce an easier WM updating task, which may allow evidencing whether the task is performed through an active or a passive updating.
