Attentional Load Effects on Emotional Content in Face Working Memory

This study investigated the role of attentional resources in processing emotional faces on working memory (WM). Participants memorised two face arrays with the same emotion but different identities and were required to judge whether the test face had the same identity as one of the previous faces. Concurrently during encoding and maintenance, a sequence of high-or-low pitched tones (high load) or white noise bursts (low load) was presented, and participants were required to count how many low-tones were heard. Experiment 1 and 2 used an emotional and neutral test face, respectively. The results revealed a significant WM impairment for sad and angry faces in the high load vs low load condition but not for happy faces. Happy faces were better recognised than other emotional faces in a high load. In Experiment 1, participants remembered better happy faces than other emotional faces. In contrast, Experiment 2 showed that performance was poorer for happy than sad faces but not for angry faces. This evidence suggests that depleting of attentional resources affects less WM for happy faces than other emotional faces, but also differential effects on WM for emotional faces depend on the presence or absence of emotion face at retrieval.

The Development of Long-Distance Viewing Direction Analysis and Recognition of Observed Objects Using Head Image and Deep Learning

In this study, we use OpenPose to capture many facial feature nodes, create a data set and label it, and finally bring in the neural network model we created. The purpose is to predict the direction of the person’s line of sight from the face and facial feature nodes and finally add object detection technology to calculate the object that the person is observing. After implementing this method, we found that this method can correctly estimate the human body’s form. Furthermore, if multiple lenses can get more information, the effect will be better than a single lens, evaluating the observed objects more accurately. Furthermore, we found that the head in the image can judge the direction of view. In addition, we found that in the case of the test face tilt, approximately at a tilt angle of 60 degrees, the face nodes can still be captured. Similarly, when the inclination angle is greater than 60 degrees, the facing node cannot be used.

Mixed emotions: Competition and context effects of emotional faces in visuospatial working memory

In this study we investigated how differing emotional faces presented in heterogenous displays compete at encoding to influence identity-location binding. Participants were shown four faces and asked to remember their identity and location while their eye-movements were recorded. Two faces carried one emotion while the other two faces carried a different emotion (angry, fear, happy, or sad; emotion was task irrelevant). Participants relocated a single neutrally expressive test face to its original position using a touchscreen. VSWM for emotional faces was modulated by the emotional context. Competition effects were complex and not based on eye-fixation time during the encoding period, stimulus factors (intensity or valence), or on perceptual or response biases. Thus, how emotional faces compete in VSWM appears to rely on more than simple arousal- or valence- biased mechanisms.

Fuzzy Face Recognition Based On Skin Texture Fusion Model

Facerecognition is a research are in computer vision and pattern recognition because of its importance in real applications like human machine interaction, video surveillance, and security systems. Here we have proposed a fuzzy model for robust facerecognition using gradient and texture information. Initially, the local binary pattern (LBP) and histogram of oriented gradients (HOG) feature of face skin from the original images are extracted. These two features are used for the development of our fuzzy model. For the analysis of faces, a content-based similarity measure is developed and used for data analysis of trained face model and test face model. The proposed algorithm is experimented on LFW, AR, and ORL face databases. The proposed fuzzy face fusion model approach shows that our proposed method is having good recognition rate compared to facerecognition methods developed recently.

Precise Ensemble Face Representation Given Incomplete Visual Input

Humans can recognize faces in the presence of environmental noise. Here, we explore whether ensemble perception of faces is similarly robust. Is summary statistical information available from crowds of faces that are visually incomplete? Observers viewed sets of faces varying in identity or expression and adjusted a test face to match the perceived average. In one condition, faces amodally completed behind horizontal bars. In another condition, identical facial information was presented, but in the foreground (i.e., face parts appeared on fragmented strips in front of a background). Baseline performance was determined by performance on sets of fully visible faces. The results revealed that the ensemble representation of amodally completing sets was significantly better than the fragmented sets and marginally worse than in the fully visible condition. These results suggest that some ensemble information is available given limited visual input and supports a growing body of work suggesting that ensembles may be represented in the absence of complete visual information.

Temporal expectations modulate face image repetition suppression as indexed by event-related potentials

Repeated exposure to a stimulus leads to reduced responses of stimulus-selective sensory neurons, an effect known as repetition suppression or stimulus-specific adaptation. Several influential models have been proposed to explain repetition suppression within hierarchically-organised sensory systems, with each specifying different mechanisms underlying repetition effects. We manipulated temporal expectations within a face repetition experiment to test a critical prediction of the predictive coding model of repetition suppression: that repetition effects will be larger following stimuli that appear at expected times compared to stimuli that appear at unexpected times. We recorded event-related potentials from 18 participants and mapped the spatiotemporal progression of repetition effects using mass univariate analyses. We then assessed whether the magnitudes of observed face image repetition effects were influenced by temporal expectations. In each trial participants saw an adapter face, followed by a 500ms or 1000ms interstimulus interval (ISI), and then a test face, which was the same or a different face identity to the adapter. Participants’ expectations for whether the test face would appear after a 500ms ISI were cued by the sex of the adapter face. Our analyses revealed multiple repetition effects with distinct scalp topographies, extending until at least 800ms from stimulus onset. An early (158-203ms) repetition effect was larger for stimuli following surprising, rather than expected, 500ms ISI durations, contrary to the model predictions of the predictive coding model of repetition suppression. Later (230-609ms) repetition effects tended to be larger following expected stimulus onset times, in line with predictive coding models. Our results indicate that the relationship between repetition suppression and temporal expectation differs across the time course of the stimulus-evoked response, suggesting multiple distinct mechanisms driving repetition suppression that operate at different latencies within the visual hierarchy.Highlights- Multiple face image repetition effects identified from 162-800ms post stimulus onset- Temporal expectations influenced the magnitudes of repetition effects- Temporal expectation effects differed for early and late stimulus-evoked responses

TEN EPIQ STEPS TO IMPROVING CARE AND OUTCOMES IN RURAL TANZANIA

BACKGROUND Maternal and child health (MCH) remains a priority globally and in Mwanza Region, Tanzania, where under-five mortality exceeds 100/1000 live births. Facility-based Quality Improvement (QI) is critical to enhancing MCH service delivery. The ‘Evidence-based Practice for Improving Quality (EPIQ)’ approach aims to equip clinical providers with basic QI understanding and skills. In Canada, EPIQ introduction has led to significant newborn intensive care improvements. OBJECTIVES To adapt, pilot and evaluate an EPIQ workshop for rural Tanzania. DESIGN/METHODS The 10-step EPIQ process is introduced through a practical, clinically-focused, hands-on workshop. A team of Canadian EPIQ experts with African partnership experience initially adjusted the EPIQ package for a Tanzanian pilot. They then facilitated a one day EPIQ training-of-trainers to QI-interested Tanzanian university faculty and health managers. The new facilitators then delivered the training to selected local health providers. The EPIQ training was evaluated through facilitator and provider (1) pre/post QI-focused knowledge tests, (2) pre/post QI confidence surveys and (3) post-workshop satisfaction surveys. Post training semi-structured group interviews also collected feedback on workshop content and format from facilitators. Written surveys and tests were analyzed using descriptive statistics and aggregate scores; semi-structured interview notes were reviewed for key themes, recommendations and representative quotations. RESULTS Workshop content including flipcharts, workbooks and locally-relevant cases were prepared. In September 2017, workshops were delivered to 16 facilitators and 29 providers in Mwanza. Post-workshop, overall knowledge scores increased by +7.6% (facilitators) and +2.1% (providers). Aggregate confidence survey scores (5-point Likert) increased for both groups by a median increase of 1 (20%). Participant workshop satisfaction scores averaged 4.7/5. Interviews suggested indicated content was perceived as very relevant however too heavy for allocated time; certain wording was too complex for the language setting. Participants reported that the small group and hands-on format encouraged skill development and EPIQ tools equipped for critical thinking and problem solving. It was strongly recommended to increase workshop length to two days. CONCLUSION A clinically-focused, participatory EPIQ training was feasible and well-received in this setting. Despite self-reported confidence increase, a lacking associated knowledge increase may reflect content too complex, limited workshop duration or poor knowledge test face validity. Future considerations should include revised content and/or knowledge testing tool, extended length, and post-workshop implementation follow-up.

Cross-cultural adaptation and validation of the Protective Nursing Advocacy Scale for Brazilian nurses

Objective: to adapt culturally and validate the Protective Nursing Advocacy Scale for Brazilian nurses.Method: methodological study carried out with 153 nurses from two hospitals in the South region of Brazil, one public and the other philanthropic. The cross-cultural adaptation of the Protective Nursing Advocacy Scale was performed according to international standards, and its validation was carried out for use in the Brazilian context, by means of factor analysis and Cronbach's alpha as measure of internal consistency.Results: by means of evaluation by a committee of experts and application of pre-test, face validity and content validity of the instrument were considered satisfactory. From the factor analysis, five constructs were identified: negative implications of the advocacy practice, advocacy actions, facilitators of the advocacy practice, perceptions that favor practice advocacy and barriers to advocacy practice. The instrument showed satisfactory internal consistency, with Cronbach's alpha values ranging from 0.70 to 0.87.Conclusion: it was concluded that the Protective Nursing Advocacy Scale - Brazilian version, is a valid and reliable instrument for use in the evaluation of beliefs and actions of health advocacy, performed by Brazilian nurses in their professional practice environment.
