Crossmodal transfer of perceptual learning: Evidence from the recognition of first and second language characters in young children.

Crossmodal transfer of learning is a neurocognitive process whereby a learner's experience and knowledge acquired through one sensory mode enable him/her to perform a similar task using a different sensory mode. This study examined the transfer of (mostly) visually acquired knowledge of first- and second-language characters to the tactile modality typically not used in that acquisition process. Two experiments were conducted, one to assess letter recognition skills and one to assess digit recognition skills in both Bangla and English, in 30 sighted young children who had mastered those characters through sensory learning in natural settings. Results unequivocally demonstrated that children were able to recognize/classify the first and second language letters or digits presented not only to the (trained) visual modality but to the (untrained) tactile modality as well, and as expected, with greater recognition accuracy and shorter recognition time in the former than the latter modality. Their character recognition performance was found to be significantly influenced not by language but by character type, with digits being more accurately and more speedily recognized than letters. Moreover, language-task modality interaction was found to mediate letter recognition accuracy, digit recognition accuracy, and digit recognition time, whereas character type-task modality interaction was found to significantly mediate character recognition time only. The ecological and theoretical significance of these findings is discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Do we enjoy what we sense and perceive? A dissociation between aesthetic appreciation and basic perception of environmental objects or events.

This integrative review rearticulates the notion of human aesthetics by critically appraising the conventional definitions, offerring a new, more comprehensive definition, and identifying the fundamental components associated with it. It intends to advance holistic understanding of the notion by differentiating aesthetic perception from basic perceptual recognition, and by characterizing these concepts from the perspective of information processing in both visual and nonvisual modalities. To this end, we analyze the dissociative nature of information processing in the brain, introducing a novel local-global integrative model that differentiates aesthetic processing from basic perceptual processing. This model builds on the current state of the art in visual aesthetics as well as newer propositions about nonvisual aesthetics. This model comprises two analytic channels: aesthetics-only channel and perception-to-aesthetics channel. The aesthetics-only channel primarily involves restricted local processing for quality or richness (e.g., attractiveness, beauty/prettiness, elegance, sublimeness, catchiness, hedonic value) analysis, whereas the perception-to-aesthetics channel involves global/extended local processing for basic feature analysis, followed by restricted local processing for quality or richness analysis. We contend that aesthetic processing operates independently of basic perceptual processing, but not independently of cognitive processing. We further conjecture that there might be a common faculty, labeled as aesthetic cognition faculty, in the human brain for all sensory aesthetics albeit other parts of the brain can also be activated because of basic sensory processing prior to aesthetic processing, particularly during the operation of the second channel. This generalized model can account not only for simple and pure aesthetic experiences but for partial and complex aesthetic experiences as well.

Comparative analysis of IVF-ICSI outcomes between advanced and early stage of endometriosis stimulated with HMG.

INTRODUCTION: Endometriosis is a challenging disease to treat, and patients may eventually need in vitro fertilisation with Intracytoplasmic sperm injection (IVF/ICSI) to conceive after other modalities failed. There are inconsistent outcomes of IVF performance in patients with endometriosis especially with highly purified human menotropin gonadotrophin (hMG). This study was commenced to determine whether the use of hMG affects the IVF outcome in different stage of endometriosis. MATERIALS AND METHODS: This is an observational study. Eighty-seven women who had endometriosis confirmed surgically and underwent IVF/ICSI treatment, stimulated with hMG alone were included. Based on the revised American Society for Reproductive Medicine (rASRM), the participants were classified as early endometriosis (I/II) (n=39) or advanced endometriosis (III/IV) (n=35). The main outcome measures used were clinical pregnancy rate. RESULTS: Women with advanced endometriosis had a lower oocyte yield, less good quality day-3 embryos and lower clinical pregnancy rate compared with the mild endometriosis. However, higher fertilisation rate were recorded in advanced stage endometriosis compared to milder disease. CONCLUSIONS: The rASRM classification of endometriosis is valuable in predicting IVF outcome as advanced endometriosis performs poorly compared to a milder disease. Highly purified hMG could be an alternative as an ovarian stimulation in endometriosis.

Perception and Appreciation of Tactile Objects: The Role of Visual Experience and Texture Parameters.

This exploratory study was designed to examine the effects of visual experience and specific texture parameters on both discriminative and aesthetic aspects of tactile perception. To this end, the authors conducted two experiments using a novel behavioral (ranking) approach in blind and (blindfolded) sighted individuals. Groups of congenitally blind, late blind, and (blindfolded) sighted participants made relative stimulus preference, aesthetic appreciation, and smoothness or softness judgment of two-dimensional (2D) or three-dimensional (3D) tactile surfaces through active touch. In both experiments, the aesthetic judgment was assessed on three affective dimensions, Relaxation, Hedonics, and Arousal, hypothesized to underlie visual aesthetics in a prior study. Results demonstrated that none of these behavioral judgments significantly varied as a function of visual experience in either experiment. However, irrespective of visual experience, significant differences were identified in all these behavioral judgments across the physical levels of smoothness or softness. In general, 2D smoothness or 3D softness discrimination was proportional to the level of physical smoothness or softness. Second, the smoother or softer tactile stimuli were preferred over the rougher or harder tactile stimuli. Third, the 3D affective structure of visual aesthetics appeared to be amodal and applicable to tactile aesthetics. However, analysis of the aesthetic profile across the affective dimensions revealed some striking differences between the forms of appreciation of smoothness and softness, uncovering unanticipated substructures in the nascent field of tactile aesthetics. While the physically softer 3D stimuli received higher ranks on all three affective dimensions, the physically smoother 2D stimuli received higher ranks on the Relaxation and Hedonics but lower ranks on the Arousal dimension. Moreover, the Relaxation and Hedonics ranks accurately overlapped with one another across all the physical levels of softness/hardness, but not across the physical levels of smoothness/roughness. These findings suggest that physical texture parameters not only affect basic tactile discrimination but differentially mediate tactile preferences, and aesthetic appreciation. The theoretical and practical implications of these novel findings are discussed.

"I don't know why I am in hospital": amnesia in non-fatal hanging.

There is an extreme dearth of empirical studies assessing the neuropsychiatric outcome of non-fatal hanging that indicates little attention to the area has been paid. We aimed to report the memory disturbances of 14 cases after an immediate non-fatal hanging attempt. We conducted the study from August 2020 to June 2021 and collected data from 14 hospitalized patients after an immediate non-fatal hanging attempt. We conducted series of clinical examinations to assess the memory disturbance and recorded it. Among the 14 cases, four (28.8%) were males and the rest ten (71.2%) were females. The mean age of the cases was 25.28 ± 8.19 years ranging from 15-40 years. All the cases had retrograde amnesia while six (42.9%) had both anterograde and retrograde amnesia. The current pilot study reported the distribution of memory disturbances among fourteen cases of non-fatal hanging that adds preliminary findings to the under-researched area and warrants further empirical studies to generalize the study results.

Neutrophil-to-lymphocyte ratio and C-reactive protein in non-fatal suicidal attempts: A cross-sectional pilot study in Bangladesh.

BACKGROUND: Precise identification of risk factors for suicide has been found as fundamentally challenging for the stakeholders. In search of that, the determination of potential biological markers of suicide has been scrutinizing in recent days. However, replicative studies across the culture and time are warranted to utilize the biomarkers in decision-making while considering suicide prevention. OBJECTIVES: We aimed to measure the neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) in non-fatal suicidal attempts. METHODS: This cross-sectional study was conducted from August 2020 to May 2021. Data were collected from 26 hospitalized patients after an immediate non-fatal suicidal attempt. We collected blood samples and assessed the complete blood count, NLR, and CRP. Data were analyzed by Statistical Package for the Social Science version 24.0 and Microsoft Excel software. We performed the independent Mann-Whitney U test to determine the variations between the groups. A value <.05 was considered as the level of significance. RESULTS: The mean age of the study population was 24.1 (±7.3), more than half of them (n = 19, 73.1%) were female. The mode of attempt was either hanging (n = 13, 50.0%) or poisoning (n = 13, 50.0%). The previous attempt was noted in 12 (46.2%) cases. The mean CRP level was 16.8 (±30.2) mg/L and the mean NLR level was 8.3 (±6.8) for the total sample. Both the CRP and NLR were significantly higher among those who attempted hanging (P = .019 and .001). CONCLUSIONS: The current study revealed preliminary findings on CRP and NLR among non-fatal suicides in Bangladesh where both of the parameters were significantly higher in non-fatal hanging.

Fertility preservation opportunities for cancer patients in Malaysia.

Fertility preservation is significant for oncology patients to maintain their ability to start a family when they are ready. Onco-fertility, as a discipline, exists at the intersection of oncology and reproductive medicine that safeguards and expands the fertility options for cancer survivors, by facilitating early intervention and suitable treatment with favourable outcomes. Successful fertility preservation requires a comprehensive networking among the gynaecologists, oncologists, pathologists, imaging and other specialists, involved in diagnosing and treating cancer in the reproductive age group. There are several ways in which fertility can be preserved, like role of gonadotrophin releasing hormone analogues, in vitro maturation, and cryopreservation.

Neuroplasticity and Crossmodal Connectivity in the Normal, Healthy Brain.

Objective: Neuroplasticity enables the brain to establish new crossmodal connections or reorganize old connections which are essential to perceiving a multisensorial world. The intent of this review is to identify and summarize the current developments in neuroplasticity and crossmodal connectivity, and deepen understanding of how crossmodal connectivity develops in the normal, healthy brain, highlighting novel perspectives about the principles that guide this connectivity. Methods: To the above end, a narrative review is carried out. The data documented in prior relevant studies in neuroscience, psychology and other related fields available in a wide range of prominent electronic databases are critically assessed, synthesized, interpreted with qualitative rather than quantitative elements, and linked together to form new propositions and hypotheses about neuroplasticity and crossmodal connectivity. Results: Three major themes are identified. First, it appears that neuroplasticity operates by following eight fundamental principles and crossmodal integration operates by following three principles. Second, two different forms of crossmodal connectivity, namely direct crossmodal connectivity and indirect crossmodal connectivity, are suggested to operate in both unisensory and multisensory perception. Third, three principles possibly guide the development of crossmodal connectivity into adulthood. These are labeled as the principle of innate crossmodality, the principle of evolution-driven 'neuromodular' reorganization and the principle of multimodal experience. These principles are combined to develop a three-factor interaction model of crossmodal connectivity. Conclusions: The hypothesized principles and the proposed model together advance understanding of neuroplasticity, the nature of crossmodal connectivity, and how such connectivity develops in the normal, healthy brain.

Haptic aesthetics in the blind: A behavioral and fMRI investigation.

Understanding perception and aesthetic appeal of arts and environmental objects, what is appreciated, liked, or preferred, and why, is of prime importance for improving the functional capacity of the blind and visually impaired and the ergonomic design for their environment, which however so far, has been examined only in sighted individuals. This paper provides a general overview of the first experimental study of tactile aesthetics as a function of visual experience and level of visual deprivation, using both behavioral and brain imaging techniques. We investigated how blind people perceive 3D tactile objects, how they characterize them, and whether the tactile perception, and tactile shape preference (liking or disliking) and tactile aesthetic appreciation (judging tactile qualities of an object, such as pleasantness, comfortableness etc.) of 3D tactile objects can be affected by the level of visual experience. The study employed innovative behavioral measures, such as new forms of aesthetic preference-appreciation and perceptual discrimination questionnaires, in combination with advanced functional Magnetic Resonance Imaging (fMRI) techniques, and compared congenitally blind, late-onset blind and blindfolded (sighted) participants. Behavioral results demonstrated that both blind and blindfolded-sighted participants assessed curved or rounded 3D tactile objects as significantly more pleasing than sharp 3D tactile objects, and symmetric 3D tactile objects as significantly more pleasing than asymmetric 3D tactile objects. However, as compared to the sighted, blind people showed better skills in tactile discrimination as demonstrated by accuracy and speed of discrimination. Functional MRI results demonstrated that there was a large overlap and characteristic differences in the aesthetic appreciation brain networks in the blind and the sighted. As demonstrated both populations commonly recruited the somatosensory and motor areas of the brain, but with stronger activations in the blind as compared to the sighted. Secondly, sighted people recruited more frontal regions whereas blind people, in particular, the congenitally blind, paradoxically recruited more 'visual' areas of the brain. These differences were more pronounced between the sighted and the congenitally blind rather than between the sighted and the late-onset blind, indicating the key influence of the onset time of visual deprivation. Understanding of the underlying brain mechanisms should have a wide range of important implications for a generalized cross-sensory theory and practice in the rapidly evolving field of neuroaesthetics, as well as for 'cutting-edge' rehabilitation technologies for the blind and the visually impaired.

The right way to kiss: directionality bias in head-turning during kissing.

Humans have a bias for turning to the right in a number of settings. Here we document a bias in head-turning to the right in adult humans, as tested in the act of kissing. We investigated head-turning bias in both kiss initiators and kiss recipients for lip kissing, and took into consideration differences due to sex and handedness, in 48 Bangladeshi heterosexual married couples. We report a significant male bias in the initiation of kissing and a significant bias in head-turning to the right in both kiss initiators and kiss recipients, with a tendency among kiss recipients to match their partners' head-turning direction. These interesting outcomes are explained by the influences of societal learning or cultural norms and the potential neurophysiological underpinnings which together offer novel insights about the mechanisms underlying behavioral laterality in humans.

The Parental Bonding Instrument: A psychometric measure to assess parenting practices in the homes in Bangladesh.

There is growing importance of the Parental Bonding Instrument (PBI) in clinical practice and research on parenting and parental bonding. Since the development of this diagnostic tool (Parker et al., Brit. J. Med. Psycho.1979; 52:1-10), a number of validation studies have been done in various cultures. The aim of the present study was to translate the measure into Bangla and validate in Bangladeshi culture. A total of 200 adolescents participated in the study. Exploratory factor analysis (EFA) of the data from 191 participants (who provided complete responses) identified a two-factor (Care and Overprotection) structure of the PBI with 17 items. The two factors together explained 44.18% of the total variance. The factors showed moderate to very high internal consistency (Cronbach's α=0.863 for Care; 0.622 for Overprotection), and very strong convergent and discriminant validity as evident by their correlations with the measures of cognitive distortions and antisocial behaviors. In line with the original tool we defined four types of parenting style, such as Affectionate constraint, Affectionless control, Optimal parenting, and Neglectful parenting. This study opens the door of future research on parenting practices and parent-child relationships in Bangladesh.

Anticlockwise or clockwise? A dynamic Perception-Action-Laterality model for directionality bias in visuospatial functioning.

Orientation bias and directionality bias are two fundamental functional characteristics of the visual system. Reviewing the relevant literature in visual psychophysics and visual neuroscience we propose here a three-stage model of directionality bias in visuospatial functioning. We call this model the 'Perception-Action-Laterality' (PAL) hypothesis. We analyzed the research findings for a wide range of visuospatial tasks, showing that there are two major directionality trends in perceptual preference: clockwise versus anticlockwise. It appears these preferences are combinatorial, such that a majority of people fall in the first category demonstrating a preference for stimuli/objects arranged from left-to-right rather than from right-to-left, while people in the second category show an opposite trend. These perceptual biases can guide sensorimotor integration and action, creating two corresponding turner groups in the population. In support of PAL, we propose another model explaining the origins of the biases - how the neurogenetic factors and the cultural factors interact in a biased competition framework to determine the direction and extent of biases. This dynamic model can explain not only the two major categories of biases in terms of direction and strength, but also the unbiased, unreliably biased or mildly biased cases in visuosptial functioning.

The How I Think questionnaire: Assessing its psychometric properties in Bangladeshi culture.

There is growing importance of the How I Think (HIT) questionnaire in clinical practice and cognitive research. Since the development of the HIT (Barriga and Gibbs, Aggress. Behav., 1996; 22: 333-343), a number of validation studies have been done in various cultures. The aim of the present study was to translate the instrument into Bangla and validate in Bangladeshi culture. A total of 200 adolescents participated in the study. Exploratory factor analysis (EFA) of the data from 191 participants (88 girls and 103 boys; who provided complete responses) identified a four-factor structure of the HIT with 27 items. The four factors namely 'Catastrophizing and mislabeling', 'Emotional reasoning', 'Self-centeredness and blaming' and 'Overgeneralization' together explained 39.611% of the total variance. In line with the original scale we also defined four types of antisocial behavior. The HIT and its factors showed acceptable to good internal consistency (Cronbach's α=.83 for the HIT, and .40-.77 for its factors), and strong construct validity as revealed by the evidence of convergent and discriminant validity. Thus the Bangla version HIT appears to be valid and reliable, and therefore may be used in further research on cognitive distortions and antisocial behaviors in Bangladesh.

Pregnancy outcomes with a primary complaint of perception of reduced fetal movements.

Reduced fetal movement is a worrisome common complaint, not only for mothers but also for the attending medical personnel. The aim of this study was to analyse the pregnancy outcomes of women who presented primarily with reduced fetal movements (RFM). A retrospective study was performed based on patients' perception alone. Obstetric, past medical history, current presentation and outcomes of pregnancy were analysed. A total of 230 case notes were reviewed, with the majority being primigravidae. Less than half (48.7%) of the women had spontaneous labour, 45.7% had induction and 5.6% had elective caesarean section. There were no maternal complications in 97.4% (n = 224) of them. About 0.9% (n = 2) and 1.7% (n = 4) had primary postpartum haemorrhage and extended perineal tear, respectively. Although there was no major neonatal mortality and morbidity, until a randomised trial with a significant sample is conducted in the management of RFM, careful selections for elective delivery or conservative management would prevent untoward complications.

The Internet Addiction Test: assessing its psychometric properties in Bangladeshi culture.

There is growing importance of the Internet Addiction Test (IAT) in Internet addiction research around the world. Since the development of the IAT (Young, 1996, 1998), a number of validation studies have been done in various cultures. The aim of this study was to translate the instrument into Bangla and validate in Bangladeshi culture, a culture vulnerable to Internet addiction. A total of 177 Internet users (77 females and 100 males) participated in the study. Exploratory factor analysis (EFA) of the data from 172 participants (who provided complete responses) identified a four factor structure of the IAT with 18 items. The four factors namely 'Neglect of duty', 'Online dependence', 'Virtual fantasies', and 'Privacy and self-defense' together explained 55.68% of the total variance. Problematic (moderate/excessive) users on the IAT scored, on average, higher on each of the four IAT factors as compared to average or non-problematic (minimal) users consistently across genders. The IAT and its factors showed good internal consistency (Cronbach's α=.89 for the IAT, and .60-.84 for the factors), strong convergent and discriminant validity. Thus, the Bangla version IAT appears to be valid and reliable and therefore may be used in further research on Internet addiction in the country.

Configurational asymmetry in vernier offset detection.

Two psychophysical experiments were conducted at the horizontal and vertical orientations respectively, demonstrating substantial main effect of configuration, but no effect of offset direction on vernier acuity. In Experiment 1, a pair of horizontal bars were arranged side by side with a large gap between them. The observers were, on average, significantly better at discriminating a vertical offset if the right-hand bar was below the left-hand bar than vice versa, regardless of which bar they experienced as displaced and which as constant. A similar asymmetry was evident in Experiment 2 where observers judged horizontal offset for a pair of vertically oriented bars, where one was placed above the other. In this case average performance was better if the upper bar was on the right of the lower bar rather than on its left. There were large individual variations in the asymmetrical trend, but the effect could not be explained by subjective response bias. Furthermore, vernier acuity improved significantly and the asymmetry decreased more or less as a function of training. The average asymmetrical trend was consistent across training days and across two orientations, which indicates that the processing of line vernier stimuli is possibly configuration-specific in the cardinal orientation.

Foot and mouth disease in animals in Sharkia governorate - Egypt.

This study was carried out to determine the current state of foot and mouth disease (FMD) in different animal species in Sharkia governorate in Egypt. In addition, we investigated the spreading of the virus through water and soil in the animal environment as well as by rodents. The isolation rates of FMD virus in tissue culture were 39.6%, 11.4%, 41.2% and 100% for cattle, buffalo, sheep and goat respectively. All animals did not show any clinical signs for FMD. In addition, the virus was isolated from the milk of an animal as well as from a water sample while all soil samples were negative.
