Kalpana P, Anandan R, Hussien AG, Migdady H, Abualigah L

Sci Rep, 2024 Apr 15;14(1):8660.
PMID: 38622177 DOI: 10.1038/s41598-024-56393-8

Agriculture plays a pivotal role in the economic development of a nation, but, growth of agriculture is affected badly by the many factors one such is plant diseases. Early stage prediction of these disease is crucial role for global health and even for game changers the farmer's life. Recently, adoption of modern technologies, such as the Internet of Things (IoT) and deep learning concepts has given the brighter light of inventing the intelligent machines to predict the plant diseases before it is deep-rooted in the farmlands. But, precise prediction of plant diseases is a complex job due to the presence of noise, changes in the intensities, similar resemblance between healthy and diseased plants and finally dimension of plant leaves. To tackle this problem, high-accurate and intelligently tuned deep learning algorithms are mandatorily needed. In this research article, novel ensemble of Swin transformers and residual convolutional networks are proposed. Swin transformers (ST) are hierarchical structures with linearly scalable computing complexity that offer performance and flexibility at various scales. In order to extract the best deep key-point features, the Swin transformers and residual networks has been combined, followed by Feed forward networks for better prediction. Extended experimentation is conducted using Plant Village Kaggle datasets, and performance metrics, including accuracy, precision, recall, specificity, and F1-rating, are evaluated and analysed. Existing structure along with FCN-8s, CED-Net, SegNet, DeepLabv3, Dense nets, and Central nets are used to demonstrate the superiority of the suggested version. The experimental results show that in terms of accuracy, precision, recall, and F1-rating, the introduced version shown better performances than the other state-of-art hybrid learning models.

Memory and time: Backward and forward telescoping in Alzheimer's disease

El Haj M, Janssen SMJ, Antoine P

Brain Cogn, 2017 10;117:65-72.
PMID: 28629646 DOI: 10.1016/j.bandc.2017.06.005

Backward and forward telescoping are opposite timing biases. The former refers to misattributing events to earlier dates, whereas the latter refers to misattributing events to later dates. The present study investigated both biases in participants with Alzheimer's Disease (AD) and healthy older adults, matched on age, sex, and education level. Participants were asked to recall the years when five remote and five recent public events had occurred. They were also assessed with a cognitive and clinical battery that included a context memory task on which they had to associate letters and locations. Results showed backward telescoping for recent events and forward telescoping for remote events in AD participants and older adults. Furthermore, poorer context recall was observed in AD participants and older adults displaying backward telescoping than in those displaying forward telescoping. These findings suggest an association between the amount of contextual information recalled and the direction of the timing bias. Backward telescoping can be associated with deficiencies in retrieving context characteristics of events, which have been associated with retrograde amnesia and pathological changes to the hippocampus in AD.

Ingatan palsu dalam kalangan kanak-kanak Pra Sekolah: satu bukti kewujudan ingatan palsu daripada eksperimen ingatan

Khairudin R, Charyna AR

Jurnal Psikologi Malaysia, 2010;olume 24:111-121.

This study aimed to investigate the occurrence of false memory in preschool children aged 3 to 6 years old. Three experiments were conducted using the traditional measurements of memory: free recall (experiment 1), cued recall (experiment 2) and recognition (experiment 3). A total of 24 children who were divided into three groups of 8, participated in the study. Result of experiment 1 showed a significant effect of categorical information on false memory. Preschool children were more likely to be influenced by false memory when the information was carried object category. Results if experiment 2 showed a significant difference in types of questions. More false memories were created for misleading questions than leading questions. Experiment 3 demonstrated that the preschool children were more likely to choose distracter pictures that target pictures. Within the distracter pictures, participants chose more false distracters than leading distracters. Implication of the findings suggests a strong evidence for the occurence of false memory in preschool children. The size of false memory effect was determined by the type of information presented to the children.

Prevalence of energy intake misreporting in Malay children varies based on application of different cut points

Yang WY, Burrows T, Collins CE, MacDonald-Wicks L, Williams LT, Chee WS

J Trop Pediatr, 2014 Dec;60(6):472-5.
PMID: 25273889 DOI: 10.1093/tropej/fmu052

This study aimed to identify the prevalence of energy misreporting amongst a sample of Malay children aged 9-11 years (n = 14) using a range of commonly used cut points. Participants were interviewed using repeated 24 h dietary recalls over three occasions. The Goldberg equations (1991 and 2000), Torun cut points and the Black and Cole method were applied to the data. Up to 11 of 14 children were classified as misreporters, with more under-reporters (between seven and eight children) than over-reporters (four or less children). There were significant differences in the proportion of children classified as energy misreporters when applying basal metabolic rate calculated using FAO/UNU/WHO (1985) and Malaysian-specific equations (p < 0.05). The results show that energy misreporting is common amongst Malay children, varying according to cut point chosen. Objective evaluation of total energy expenditure would help identify which cut point is appropriate for use in Malay paediatric populations.

The role of chunking in drawing Rey complex figure

Obaidellah UH, Cheng PC

Percept Mot Skills, 2015 Apr;120(2):535-55.
PMID: 25706345 DOI: 10.2466/24.PMS.120v17x6

The study investigated the effects of chunking and perceptual patterns that guide the drawings of Rey complex figure. Ten adult participants (M age=22.2 yr., SD=4.1) reproduced a single stimulus in four drawing modes including delayed recall, tracing, copying, and immediate recall across 10 sessions producing a total of 400 trials. It was hypothesized that the effect of chunking is most obvious in the free recall tasks than in the tracing or copying tasks. Measures such as pauses, patterns of drawings, and transitions among patterns of drawings suggested that participants used chunking to aid rapid learning of the diagram. The analysis of the participants' sequence of chunk production further revealed that they used a spatial schema to organize the chunks. Findings from this study provide additional evidence to support prior studies that claim graphical information is hierarchically organized.

Reliability of reasons for early termination of breastfeeding: application of a bivariate probability model with sample selection to data from surveys in Malaysia in 1976-77 and 1988-89

Kuate-Defo B, DaVanzo J

Popul Stud (Camb), 2006 Mar;60(1):83-98.
PMID: 16464777 DOI: 10.1080/00324720500462223

Although extensively collected, data on people's reasons for their behaviour provided retrospectively have been met with some scepticism on the grounds that they may be subject to biases and errors that jeopardize their usefulness. This study investigates, for a sample of 1,327 births, the reliability with which women in Peninsular Malaysia recalled, at intervals 12 years apart, reasons for not initiating or for stopping breastfeeding less than 3 months after a birth. Overall, we find low to moderate reliability of recall. Levels of reliability are relatively high for some reasons (the child died and no or insufficient milk) but low for some others (child ill, breastfeeding inconvenient). Results from selection models show that reliability does not vary with the length of time since the child's birth but is inversely related to socio-economic status (proxied by education and employment). Social status, social norms, and health-related factors appear to be significant influences on women's consistency of reporting.

Fulltext A Food Frequency Questionnaire for Hemodialysis Patients in Bangladesh (BDHD-FFQ): Development and Validation

Ahmed S, Rahman T, Ripon MSH, Rashid HU, Kashem T, Md Ali MS, et al.

Nutrients, 2021 Dec 17;13(12).
PMID: 34960076 DOI: 10.3390/nu13124521

Diet is a recognized risk factor and cornerstone for chronic kidney disease (CKD) management; however, a tool to assess dietary intake among Bangladeshi dialysis patients is scarce. This study aims to validate a prototype Bangladeshi Hemodialysis Food Frequency Questionnaire (BDHD-FFQ) against 3-day dietary recall (3DDR) and corresponding serum biomarkers. Nutrients of interest were energy, macronutrients, potassium, phosphate, iron, sodium and calcium. The BDHD-FFQ, comprising 132 food items, was developed from 606 24-h recalls and had undergone face and content validation. Comprehensive facets of relative validity were ascertained using six statistical tests (correlation coefficient, percent difference, paired t-test, cross-quartiles classification, weighted kappa, and Bland-Altman analysis). Overall, the BDHD-FFQ showed acceptable to good correlations (p < 0.05) with 3DDR for the concerned nutrients in unadjusted and energy-adjusted models, but this correlation was diminished when adjusted for other covariates (age, gender, and BMI). Phosphate and potassium intake, estimated by the BDHD-FFQ, also correlated well with the corresponding serum biomarkers (p < 0.01) when compared to 3DDR (p > 0.05). Cross-quartile classification indicated that <10% of patients were incorrectly classified. Weighted kappa statistics showed agreement with all but iron. Bland-Altman analysis showed positive mean differences were observed for all nutrients when compared to 3DDR, whilst energy, carbohydrates, fat, iron, sodium, and potassium had percentage data points within the limit of agreement (mean ± 1.96 SD), above 95%. In summary, the BDHD-FFQ demonstrated an acceptable relative validity for most of the nutrients as four out of the six statistical tests fulfilled the cut-off standard in assessing dietary intake of CKD patients in Bangladesh.

Don't stare, unless you don't want to remember: Maintaining fixation compromises autobiographical memory retrieval

Lenoble Q, Janssen SMJ, El Haj M

Memory, 2019 02;27(2):231-238.
PMID: 30021485 DOI: 10.1080/09658211.2018.1501068

This study has developed an original approach to the relationship between eye movements and autobiographical memory, by investigating how maintained fixation could influence the characteristics of retrieved memories. We invited participants to retrieve autobiographical memories in two conditions: while fixating a cross at the centre of a screen and while freely exploring the screen. Memories retrieved during the maintained fixation condition were less detailed and contained less visual imagery than those retrieved during the free-gaze condition. Memories retrieved during the maintained fixation condition were retrieved slower and took less time to describe than those retrieved during the free-gaze condition. As for the characteristics of eye movements, analysis showed fewer and longer fixations as well as fewer saccades in the maintained fixation than in the free-gaze condition. Maintaining fixation is likely to tax cognitive resources that are necessary for the reconstruction of autobiographical memory. Our findings demonstrate how maintained fixation may result in a more effortful construction of autobiographical memory and memories with lower spatiotemporal specificity and poorer mental images.

Fulltext Working memory load influence on control of attention among Malaysian undergraduates

Khairun Emylyana, Amin, Fitri Suraya, Mohamad

Journal of Cognitive Sciences & Human Development, 2021;7(1):0-0.
MyJurnal

The study investigates how working memory affects students' control of attention. A quasi-experimental research is conducted individually on 52 undergraduates of a public university in Malaysia, enrolled in various full-time undergraduate programmes, using Sternberg memory task and Task-switching tests. The reaction time is taken in milliseconds (ms) to differentiate the results for both tasks. The analysis revealed that when memory load was increased, reaction time also escalated. In the task-switching test, when one task was given at any one time, the reaction time was swift; however, when two or more tasks were integrated into one task, the reaction time would subsequently decelerated. Although the study also revealed that there is no significant difference between genders in terms of handling memory load and taskswitching. However, a significant relationship was observed in performances between memory load and task-switching. It is also evidenced in the study that when memory load increases, it compoundsthe reaction time for task-switching. Results from the study inform course instructors to be aware of cognitive load when chunking information and assigning tasks to students, as their decisions on content quantity bore an effect on what would be remembered when students learn.

The eyes of the past: larger pupil size for autobiographical memories retrieved from field perspective

El Haj M, Janssen SMJ, Lenoble Q, Robin F, Gallouj K

Neurol Sci, 2022 Jan;43(1):661-666.
PMID: 33959825 DOI: 10.1007/s10072-021-05297-w

BACKGROUND: Visual perspective during memory retrieval has mainly been evaluated with methodologies based on introspection and subjective reports. The current study investigates whether visual perspective can be evaluated with a physiological measurement: pupil dilation.
METHODS: While their pupil diameter was measured with an eye-tracker, forty-five participants retrieved one memory from a field perspective (i.e., as viewed through our own eyes) and one memory from an observer perspective (i.e., as viewed from a spectator's standpoint). After retrieval, participants rated the emotional intensity of the memories.
RESULTS: Analysis demonstrated larger pupils during the retrieval of memories from a field perspective and higher emotional intensity for memories retrieved from a field perspective.
DISCUSSION: The larger pupils for memories recalled from a field perspective could, however, not be attributed to their higher emotional intensity. These findings suggest that pupil dilation could be used as a physiological assessment of visual perspective during memory retrieval.

Effects of white noise on word recall performance and brain activity in healthy adolescents with normal and low auditory working memory

Othman E, Yusoff AN, Mohamad M, Abdul Manan H, Abd Hamid AI, Giampietro V

Exp Brain Res, 2020 Apr;238(4):945-956.
PMID: 32179941 DOI: 10.1007/s00221-020-05765-3

The present study examined the impact of white noise on word recall performance and brain activity in 40 healthy adolescents, split in two groups (normal and low) depending on their auditory working memory capacity (AWMC). Using functional magnetic resonance imaging, participants performed a backward recall task under four different signal-to-noise ratio (SNR) conditions: 15, 10, 5, and 0-dB SNR. Behaviorally, normal AWMC individuals scored significantly higher than low AWMC individuals across noise levels. Whole-brain analyses showed brain activation not to be statistically different between groups across noise levels. In the normal group, a significant positive relationship was found between performance and number of activated voxels in the right superior frontal gyrus. In the low group, significant positive correlations were found between performance and number of activated voxels in left superior frontal gyrus, left inferior frontal gyrus, and left anterior cingulate cortex. These findings suggest that the strategic structure involved in the enhancement of AWM performance may differ in normal and low AWMC individuals.

Reliability of retrospective survey data on infant feeding

Haaga JG

Demography, 1988 May;25(2):307-14.
PMID: 3396753

This article examines retest reliability and digit preference in retrospective survey data on breastfeeding duration and type of supplementary food, covering three decades and reported by more than 1200 Malaysian women. Women with little or no education, rural residents, and those of Malay ethnicity are found to give less reliable data. In a logistic regression analysis, these respondent characteristics are more important determinants of data quality than the length of the recall period.

Autobiographical memory impairment among Rohingya refugee people: roles of direct and indirect trauma exposures and PTSD symptom severity

Khan S, Haque S

Cogn Emot, 2021 12;35(8):1573-1587.
PMID: 34644246 DOI: 10.1080/02699931.2021.1990018

Literature indicates that trauma exposure leads to autobiographical memory (AM) impairment, but the differential effects of direct and indirect trauma on memory remain unclear. We investigated AMs of 100 Rohingya refugees (Meanage = 35.79; SDage = 15.36) recruited from camps in Bangladesh and communities in Malaysia. Each participant retrieved ten memories to word cues and rated to what extent those memories were self-defining on a 5-point scale. They also completed the PTSD-8 scale and a trauma checklist reporting the types of traumatic events they experienced. Results showed that participants with frequent exposure to direct and indirect trauma recalled more traumatic memories. Surprisingly, more direct-trauma memories appeared to be specific than indirect trauma and non-trauma memories. As expected, individuals who scored higher on the PTSD-8 scale recalled more non-specific AMs. Rohingyas in Bangladesh who migrated months before data collection, thus retaining recent trauma experiences , retrieved more non-specific memories than those in Malaysia who migrated years ago. The direct trauma memories of the Malaysian cohort were more self-defining than their counterparts. The participant's ability to recall more direct trauma memories with specificity could be attributed to the repeated recall of those memories to the relevant authorities of the host countries to justify their refugee status.

The transmission and stability of cultural life scripts: a cross-cultural study

Janssen SMJ, Haque S

Memory, 2018 01;26(1):131-143.
PMID: 28585471 DOI: 10.1080/09658211.2017.1335327

Cultural life scripts are shared knowledge about the timing of important life events. In the present study, we examined whether cultural life scripts are transmitted through traditions and whether there are additional ways through which they can be attained by asking Australian and Malaysian participants which information sources they had used to generate the life script of their culture. Participants hardly reported that they had used cultural and religious traditions. They more often reported that they had used their own experiences and experiences of relatives and friends. They also reported the use of comments of relatives and friends and the use of newspapers, books, movies and television programmes. Furthermore, we examined the stability of life scripts and similarities and differences across cultures. We found that life scripts are stable cognitive structures and that there are, besides cross-cultural differences in the content, small cross-cultural differences in the valence and distribution of life script events, with the Australian life script containing more positive events and more events expected to occur before the age of 16.

Fulltext Understanding the reminiscence bump: A systematic review

Munawar K, Kuhn SK, Haque S

PLoS One, 2018;13(12):e0208595.
PMID: 30533033 DOI: 10.1371/journal.pone.0208595

One of the most consistently observed phenomena in autobiographical memory research is the reminiscence bump: a tendency for middle-aged and elderly people to access more personal memories from approximately 10-30 years of age. This systematic review (PROSPERO 2017:CRD42017076695) aimed to synthesize peer-reviewed literature pertaining to the reminiscence bump. The researchers conducted searches in nine databases for studies published between the date of inception of each database and the year 2017. Keywords used included: reminiscence, bump, peak, surge, blip, reminiscence effect, and reminiscence component. Sixty-eight quantitative studies, out of 523, met the inclusion criteria. The researchers implemented a thematic analytic technique for data extraction. Four main themes were generated: methods of memory activation/instruction for life scripts, types of memory/life scripts recalled, location of the reminiscence bump, and theoretical accounts for the bump. The two prevailing methods of memory activation implemented were the cuing method and important memories method. Three types of memories/life scripts were recalled: personal/autobiographical memory, memories for public events, and life script events. The findings illustrate differing temporal periods for the bump: approximately 10-30 years for memories for important events, approximately 5-30 years for memories that were induced by word cues, and 6-39 years for studies using life scripts. In explaining the bump, the narrative/identity account and cultural life script account received the most support.

Fulltext A review of autobiographical memory studies on patients with schizophrenia spectrum disorders

Zhang Y, Kuhn SK, Jobson L, Haque S

BMC Psychiatry, 2019 11 14;19(1):361.
PMID: 31727046 DOI: 10.1186/s12888-019-2346-6

BACKGROUND: Patients suffering from schizophrenia spectrum disorders demonstrate various cognitive deficiencies, the most pertinent one being impairment in autobiographical memory. This paper reviews quantitative research investigating deficits in the content, and characteristics, of autobiographical memories in individuals with schizophrenia. It also examines if the method used to activate autobiographical memories influenced the results and which theoretical accounts were proposed to explain the defective recall of autobiographical memories in patients with schizophrenia.
METHODS: PsycINFO, Web of Science, and PubMed databases were searched for articles published between January 1998 and December 2018. Fifty-seven studies met the inclusion criteria. All studies implemented the generative retrieval strategy by inducing memories through cue words or pictures, the life-stage method, or open-ended retrieval method. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement guidelines were followed for this review.
RESULTS: Most studies reported that patients with schizophrenia retrieve less specific autobiographical memories when compared to a healthy control group, while only three studies indicated that both groups performed similarly on memory specificity. Patients with schizophrenia also exhibited earlier reminiscence bumps than those for healthy controls. The relationship between comorbid depression and autobiographical memory specificity appeared to be independent because patients' memory specificity improved through intervention, but their level of depression remained unchanged. The U-shaped retrieval pattern for memory specificity was not consistent. Both the connection between the history of attempted suicide and autobiographical memory specificity, and the relationship between psychotic symptoms and autobiographical memory specificity, remain inconclusive. Patients' memory specificity and coherence improved through cognitive training.
CONCLUSIONS: The overgeneral recall of autobiographical memory by patients with schizophrenia could be attributed to working memory, the disturbing concept of self, and the cuing method implemented. The earlier reminiscence bump for patients with schizophrenia may be explained by the premature closure of the identity formation process due to the emergence of psychotic symptoms during early adulthood. Protocol developed for this review was registered in PROSPERO (registration no: CRD42017062643).

Relationship between blood lead concentration and nutritional status among Malay primary school children in Kuala Lumpur, Malaysia

Elias SM, Hashim Z, Marjan ZM, Abdullah AS, Hashim JH

Asia Pac J Public Health, 2007;19(3):29-37.
PMID: 18330402

A cross-sectional study was conducted to identify the relationship between blood lead concentration and nutritional status among primary school children in Kuala Lumpur. A total of 225 Malay students, 113 male and 112 female, aged 6.3 to 9.8 were selected through a stratified random sampling method. The random blood samples were collected and blood lead concentration was measured by a Graphite Furnace Atomic Absorption Spectrophotometer. The nutrient intake was determined by the 24-hour Dietary Recall method and Food Frequency Questionnaire. An anthropometric assessment was reported according to growth indices (z-scores of weight-for-age, height-for-age, and weight-for-height). The mean blood lead concentration was low (3.4 +/- 1.91 ug/dL) and was significantly different between gender. Only 14.7% of the respondents fulfilled the daily energy requirement. The protein and iron intakes were adequate for a majority of the children. However, 34.7% of the total children showed inadequate intake of calcium. The energy, protein, fat and carbohydrate intakes were significantly different by gender, that is, males had better intake than females. Majority of respondents had normal mean z-score of growth indices. Ten percent of the respondents were underweight, 2.8% wasted and 5.4% stunted. Multiple linear regression showed inverse significant relationships between blood lead concentration with children's age (beta = -0.647, p < 0.001) and per capita income (beta = -0.001, p = 0.018). There were inverse significant relationships between blood lead concentration with children's age (beta = -0.877, p = 0.001) and calcium intake (beta = -0.011, p = 0.014) and positive significant relationship with weight-for-height (beta = 0.326, p = 0.041) among those with inadequate calcium intake. Among children with inadequate energy intake, children's age (beta = -0.621, p < 0.001), per capita income (beta = -0.001, p = 0.025) and protein intake (beta = -0.019, p = 0.027) were inversely and significantly related with blood lead concentration. In conclusion, nutritional status might affect the children's absorption of lead and further investigation is required for confirmation.

Fulltext Autobiographical memory and hierarchical search strategies in depressed and non-depressed participants

Haque S, Juliana E, Khan R, Hasking P

BMC Psychiatry, 2014;14:310.
PMID: 25403551 DOI: 10.1186/s12888-014-0310-z

There is a growing body of literature showing individuals with depression and other trauma-related disorders (e.g., posttraumatic stress disorder) recall more overgeneral and less specific autobiographical memories compared to normal participants. Although the mechanisms underlying overgeneral memory are quite clear, the search strategy operated within the autobiographical knowledge base, at time of recollection, requires further exploration. The current study aimed to examine the hierarchical search sequence used to recall autobiographical memories in depressed and non-depressed participants, with a view to determining whether depressed participants exhibited truncated search strategies.
