Investigating hair cues as a mechanism underlying Black women's intersectional invisibility.

Children psychologically exclude Black women from their representations of women, but the mechanisms underlying this marginalization remain unclear. Across two studies (N = 129; 49 boys, 78 girls, two gender unreported; 79 White, 27 Black, six Latinx, five Asian, and 12 unreported), the present work tests hair texture as one possible perceptual mechanism by which this might occur. In both studies, children gender-categorized Black, White, and Asian men and women using MouseTracker. Children were slower and had more complex patterns in categorizing Black women when they had textured hair (Study 1A), but not when they had straight hair (Study 1B). Implications for the development of gender as a social category are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

An Exploratory Trial of Brief Mindfulness-Based Zentangle Art Workshops in Family Social Services during COVID-19: Transitioning from Offline to Online.

Mindfulness-based art therapy has shown to improve psychological well-being. Zentangle is an easy-to-learn, mindfulness-based art therapy suitable for everyone. We reported the transition from face-to-face to online Zentangle workshops in family social services during COVID-19. We explored feedback from face-to-face workshops and the acceptability of an online approach utilizing information communication technology (ICT) to achieve greater service reach, satisfaction, and knowledge and related outcomes. Under the Hong Kong Jockey Club SMART Family-Link Project and in collaboration with Caritas Integrated Family Service Centre-Aberdeen, this study was conducted in two phases: a four-session, face-to-face workshop (phase one) and eleven online single-session workshops (phase two) from September 2019 to September 2020. A total of 305 participants joined the workshops. Phase one participants (n = 11) reported high satisfaction (4.7 out of 5), increases in knowledge (4.2/5) and confidence (3.9/5) towards managing stress, increases in knowledge (4.1/5) and confidence (3.9/5) in showing support and care towards family members, and an increase in knowledge towards strengthening family relationships (4.0/5). Phase two participants (n = 294) also reported high satisfaction (4.7/5) and strongly agreed that ICT helped with learning Zentangle more conveniently, that they had increased knowledge and interest in Zentangle (all 4.7/5), and would definitely join the workshop again (4.8/5). The qualitative data supported the quantitative findings. We are the first to report on the utilization of ICT in an exploratory trial of brief, online Zentangle art workshops targeting the general public, with high satisfaction and positive participant experiences with ICT integration, learning Zentangle, and enhanced psychological and family well-being. This study provided preliminary evidence on the use of ICT to successfully transition face-to-face to online workshops and reach a wider audience.

Theory of mind performances in first-episode schizophrenia patients: An 18-month follow-up study.

This study examined the change of Theory of Mind (ToM) performances in patients with first-episode schizophrenia over an 18-month period since illness onset. A computerised behavioural task was utilised to assess the affective and cognitive facets of visual-based ToM. Patients' ToM performances were standardised using the norms of gender-stratified, age- and IQ-matched controls. The results showed that schizophrenia patients exhibited poorer second-order affective and cognitive ToM at baseline, but their ToM ability improved after 18 months of follow-up. Our findings do not support a longitudinal dissociation of affective from cognitive ToM in schizophrenia.

Following Instructions in Patients With Schizophrenia: The Benefits of Actions at Encoding and Recall.

The ability to follow spoken instructions is important to everyday functioning but has seldom been studied in patients with schizophrenia (SZ). Recent evidence suggests that action-based processing may facilitate the ability to follow instructions, which relies largely on working memory. In this study, we tested the hypothesis that SZ patients may also benefit from action-based advantages in following instructions. Forty-eight clinically stable SZ patients and 48 demographic- and IQ-matched controls completed a following spoken instruction span task involving varied encoding and recall conditions. While SZ patients were impaired in the overall performance of following spoken instructions, this deficit could be attributed to working memory impairment. More importantly, SZ patients showed action-based advantages both at the encoding and retrieval stage to the same extent as healthy controls. Specifically, both healthy controls and SZ patients showed improved memory performance when they additionally performed the actions, or watched the experimenter carrying out the actions compared with simply listening to spoken instructions during the encoding stage. During the retrieval stage, memory was improved when they recalled the instructions by physical enactment compared with oral repetition. The present study provides the first empirical evidence for the impairment in the ability to follow instructions in SZ. We have shown that involving action-based processing in the encoding and retrieval stage facilitated memory of instructions, indicating that the enactment advantage in working memory also applies to SZ patients. These findings provide useful insights for clinical interventions and cognitive remediation for SZ patients.

Affective experience and motivated behavior in schizophrenia spectrum disorders: Evidence from clinical and nonclinical samples.

OBJECTIVE: Individuals with schizophrenia have been found to exhibit emotion-behavior decoupling, particularly with respect to anticipated, rather than experienced events. However, previous research has focused on how emotion valence translates into motivated behavior, ignoring the fact that emotion arousal should also modulate emotion-behavior coupling. Few studies have examined emotion-behavior coupling in prepsychotic conditions. This investigation aimed to examine the nature and extent of emotion valence- and arousal-behavior coupling across the schizophrenia spectrum. METHOD: We examine how emotional valence and arousal couple with behavior in 3 groups of individuals (25 individuals with chronic schizophrenia; 27 individuals early in the disease course, and 31 individuals reporting negative schizotypal symptoms). Participants completed a task using slides to elicit emotion and evoke motivated behavior. We compared participants with their respective matched control groups to determine differences in the correspondence between self-reported emotion valence/arousal and motivated behavior. RESULTS: Both groups with schizophrenia reported similar affective experiences as their controls, whereas individuals reporting negative schizotypal symptoms showed "in-the-moment" anhedonia but not emotion-behavior decoupling. In addition, the schizophrenia groups' affective experiences corresponded less well to their behavior relative to controls. CONCLUSIONS: Our findings suggest emotion-behavior decoupling along both valence and arousal dimensions in schizophrenia but not in participants with high levels of schizotypal symptoms. Findings appear to support the idea that emotion-behavior decoupling differs in nature and extent across the schizophrenia spectrum. Interventions to recouple emotion and behavior may be particularly helpful in allowing people with schizophrenia to gain functional independence. (PsycINFO Database Record

Subjective pleasure experience in patients with recent-onset schizophrenia: A preliminary report.

Little is known about subjective pleasure experience in recent-onset schizophrenia, and its relationship with neurocognitive functions. Twenty-seven recent-onset schizophrenia people and 26 controls completed the TEPS and neuropsychological tests. The results showed that schizophrenia people self-reported less anticipatory pleasure than controls. Semantic verbal fluency was apparently correlated with anticipatory pleasure.

Environment and body contamination: a comparison of two different removal methods in three types of personal protective clothing.

BACKGROUND: This study aimed to examine the body contamination rates and environmental contamination levels during the removal of 3 types of personal protective clothing (PPC) by the individual accustomed removal method (IARM) and gown removal methods recommended by the Centers for Disease Control and Prevention (CDC). METHODS: Fifty participants performed IARM and CDC-recommended gown removal methods to remove 3 types of PPC (ie, cotton gown, water resistant gown, and plastic apron) in random order at 2 separate sessions after applying Glo Germ simulated germ lotion on the gown's surface. A video demonstrating the CDC-recommended gown removal method was shown between the 2 sessions. After PPC removal, fluorescent stains were counted by an ultraviolet scan under dim light. RESULTS: Following IARM, contaminants were splashed in the surroundings, particularly on the front part of the subject. The plastic apron and cotton gown obtained the highest and lowest contaminative hazards, respectively, to the hands, shoes, and environment. Females, nurses, and senior staff had serious hand or shoe contamination. The CDC removal method more significantly reduced body and environmental contamination of small fluorescent stains (<1 cm(2)), but not of large patches (>1 cm(2)), than IARM. CONCLUSION: The effect of gown removal, PPC type, discarding PPC location, training of infection control measures, hand hygiene, and special work shoes should be considered daily.

Visualizing macromolecular complexes with in situ liquid scanning transmission electron microscopy.

A central focus of biological research is understanding the structure/function relationship of macromolecular protein complexes. Yet conventional transmission electron microscopy techniques are limited to static observations. Here we present the first direct images of purified macromolecular protein complexes using in situ liquid scanning transmission electron microscopy. Our results establish the capability of this technique for visualizing the interface between biology and nanotechnology with high fidelity while also probing the interactions of biomolecules within solution. This method represents an important advancement towards allowing future high-resolution observations of biological processes and conformational dynamics in real-time.

Functional differences between the N-terminal domains of mouse and human myosin binding protein-C.

The N-terminus of cMyBP-C can activate actomyosin interactions in the absence of Ca2+, but it is unclear which domains are necessary. Prior studies suggested that the Pro-Ala rich region of human cMyBP-C activated force in permeabilized human cardiomyocytes, whereas the C1 and M-domains of mouse cMyBP-C activated force in permeabilized rat cardiac trabeculae. Because the amino acid sequence of the P/A region differs between human and mouse cMyBP-C isoforms (46% identity), we investigated whether species-specific differences in the P/A region could account for differences in activating effects. Using chimeric fusion proteins containing combinations of human and mouse C0, Pro-Ala, and C1 domains, we demonstrate here that the human P/A and C1 domains activate actomyosin interactions, whereas the same regions of mouse cMyBP-C are less effective. These results suggest that species-specific differences between homologous cMyBP-C isoforms confer differential effects that could fine-tune cMyBP-C function in hearts of different species.

The interface between phonetic and lexical abilities in early Cantonese language development.

Data from the Cantonese Communicative Development Inventory (CCDI) is used to review the phonological preferences of younger (16-22 months) and older (23-30 month) groups of children in the lexical items they are reported to be able to say. Analogous results to those found for English emerge from the Cantonese data: the younger group display selectivity in the initial consonants of words they say, and their preferences accord with developmental tendencies in Cantonese phonology. From children whose scores fell below the tenth percentile of the CCDI, a subset were followed up 1 year later and their linguistic progress evaluated. Only a proportion of these children were below still below the tenth percentile for vocabulary at follow-up. Their lexical immaturities were accompanied by limited phonetic abilities. The implications of the findings are discussed.
