Title: Applying Cognitive Science Principles to Promote Durable and Efficient Learning

Date: Friday, February 19, 1-2 pm 

Venue: AS4/02-08 (Psychology Department Meeting Room) 

Abstract:

Do tests only measure learning, or can they also promote learning? Should students review/practise the material they are trying to learn soon after they encounter the material or should they wait a while? During practice, should items of the same type/topic be grouped together or should they be interspersed among items of other types/topics? How we learn best may not correspond to how we think we learn best. I will talk about how basic research in cognitive psychology has yielded (nonobvious) principles about human learning and memory that have practical implications for instruction.

About the Speaker:

Sean Kang is an assistant professor in the Department of Education at Dartmouth College (USA). His research is focused on applying the cognitive science of human learning and memory towards improving instructional practice, and he currently serves as an associate editor for the journal Applied Cognitive Psychology.

Title: Cultural variations in the measurement and significance of maternal sensitivity

Date: Friday, January 29, 1-2 pm 

Venue: AS4/02-08 (Psychology Department Meeting Room) 

Abstract:

Although there is increasing interest in parenting and child development issues in Singapore, research in this field remains sparse. Local researchers and practitioners often find themselves having to rely on instruments or questionnaires developed in the West for research and programme evaluation. This is not ideal, mainly because we do not know if the instruments validly measure the same concept in Singapore, as they do in the West. This presentation discusses one recent effort in checking the relevance of a widely-used parental sensitivity measure – the Emotional Availability (EA) sensitivity scale – using a sample of Singaporean mothers and preschoolers. 

Participants were mainly from middle-class families from Chinese, Malay, Indian and ‘Other’ ethnic groups. Study 1 involved 30 mother-child dyads (children aged 4 to 6). Scores on EA sensitivity and the Maternal Behavior Q-set were highly correlated, suggesting convergent validity. In Study 2 (164 mother-child dyads), criterion validity was tested by the associations between EA sensitivity and children’s vocabulary and likeability by peers. Unlike findings from similar studies conducted in the U.S., EA sensitivity was negatively correlated with children’s likeability by female peers, suggesting that measures developed in Western contexts may not be fully applicable locally, or that the meaning of sensitivity may vary across cultures. 

About the Speaker:

 Hoi Shan is a postdoctoral fellow in the Department of Psychology, NUS. Her research focusses on cultural differences in parenting practices, and their influence on the interpretation of parent-child relationship quality and children’s developmental outcomes.

Title: Mid-Frontal Cognitive-Control Signals: a Hub for Social, Emotional, and Motivational Processing?
 
Date: 15 January, 1-2 pm
 
Venue: AS4/02-08 (Psychology Department Meeting Room)
 
Abstract:
 
Recently, cognitive neuroscientists have identified a family of neural signals that involve in realization of the need for cognitive-control. These so-called mid-frontal cognitive-control signals are enhanced, for instance, to 1) a NoGo stimulus that signals individuals to inhibit their response in a Go/NoGo task, or to 2) an important feedback that informs individuals about their performance. These mid-frontal cognitive-control signals can be quantified through ERPs (e.g., the N2 and Feedback-Related Negativity, FRN), EEG oscillations (e.g., the Frontal-Midline Theta, FMT) or fMRI (e.g., BOLD activity in the ACC). Nonetheless, it is less clear 1) how social, emotional and motivational factors modulate these cognitive-control signals, and more importantly, 2) how changes in these signals relate to decision-making. In a series of experiments, I will demonstrate, firstly, that social (e.g., cultural values), emotional (e.g., emotional-temperaments and stimulus’ valence) and motivational (e.g., monetary rewards) factors modulate these cognitive-control signals. Secondly, I will further demonstrate that these signals, in turn, predict decision-making, including 1) trial-by-trial deception behaviors as well as 2) individual-differences in delay-discounting. Hence, I argue that mid-frontal cognitive-control signals can be considered a hub that integrates social, emotional, motivational information, and ultimately influences decision-making.
About the Speaker:
 
Narun “Non” Pornpattananangkul is a postdoctoral research fellow in Dr. Rongjun Yu’s Decision Lab. He completed his Ph.D. in Brain, Behavior and Cognition at Northwestern University, USA, in 2015 where he conducted cognitive neuroscience research on cognitive-control and reward-processing. His current research at NUS is on economic decision-making, using several techniques such as EEG, fMRI, concurrent EEG-fMRI, intracranial EEG, hormone and computational modeling.

Title: Cingulate Neurobiology: Region and Subregion Models

Date: Tuesday November 24, 12-1 pm

Venue: AS4/02-08 (Psychology Department Meeting Room)

Abstract:

All neurobiology begins with anatomical localization(s). The designation of an area, region or subregion declares that functional differences exist even before functional studies are initiated. While the Brodmann map of 1909 is recognized for its various deficiencies, functional imaging research continues to rely on this early, pre-neurobiological view of cingulate cortex with its anterior and posterior cortices (ACC and PCC) that are ensconced as “labels” for structural and functional studies. One of its greatest deficiencies is the lack of a vast midcingulate region (MCC) between ACC and PCC. We will explore the cytoarchitectural, connectional, ligand binding and functional rationale for distinguishing MCC from its adjacent regions. The key feature of MCC is its motor output system to the spinal cord from the cingulate premotor areas that engage in feedback-mediated decision making. This contrasts with ACC which is engaged in autonomic regulation and emotional activations and PCC that is engaged in spatial orientation in multisensory spaces and personally relevant contexts. Each of the four regions (including retrosplenial cortex; RSC) are not homogeneous; i.e., they each are comprised of two subregions for a total of eight which emerge from anatomical and functional analyses. These subregions are not simply “labels” but rather models of structure/function entities. The predictive validity of such models will be evaluated by the extent to which particular psychiatric disorders and drug therapeutics impact each subregion; in depression for ACC, migraine, obsessive-compulsive disorder, attention-deficit/hyperactivity disorder, and Tourette syndrome for aMCC, progressive supranuclear palsy, unipolar depression and PTSD for pMCC and Alzheimer’s disease for PCC. Further, methylphenidate, Ibuprofen, and ketamine have unique actions in aMCC that suggest mechanisms for actions in ADHD and pain control. Thus, the 8 subregion models of cingulate cortex have been extensively validated with modern imaging techniques and should be a part of all studies of cingulate cortex.

Title: Continuity along the Autism Spectrum in Perceptual and Biological Markers

Date: Thursday 19 November, 12-1 pm

Venue: AS4/02-08 (Psychology Department Meeting Room)

Abstract:

Substantial research effort has been invested in identifying a unique cognitive or perceptual profile for Autism Spectrum Disorder (ASD). A potential application of this work is in identifying early neurocognitive markers for the disorder, with potential biological markers also under intense investigation. Our research at UWA has combined investigations of children with ASD with investigations that compare groups of young adults screened for high versus low levels of mild autistic-like traits. These two lines of research provide evidence that children with ASD and adults with high levels of autistic-like traits share a profile characterized by an advantage in low-level visual search processes but a disadvantage in visual integration. Other work from our group provides preliminary evidence that physical features may also provide subtle markers for autism.  In particular, evidence from studies of clinical groups and from groups on the broader spectrum converge in suggesting that autism is characterized by the masculinization of facial features.

About the Speaker:

 Title: How does language distance between first language (L1) and second language (L2) affect the L2 brain network? An fMRI study of Korean-Chinese-English trilinguals

Date: Wednesday 11 November, 12-1 pm

Venue: AS4/02-08 (Psychology Department Meeting Room)

Abstract:

The present study tested the hypothesis that language distance between first language (L1) and second language (L2) influences the assimilation and accommodation pattern in Korean-Chinese-English trilinguals. The distance between English and Korean is smaller than that between Chinese and Korean in terms of orthographic transparency, because both English and Korean are alphabetic, whereas Chinese is logographic. During fMRI, Korean trilingual participants performed a visual rhyming judgment task in three languages (Korean, Chinese, and English). Two L1 control groups were native Chinese and English speakers performing the task in their native languages. The results suggest that the brain network involved in L2 reading is similar to the L1 network when L2 and L1 are similar in orthographic transparency, while significant accommodation is expected when L2 is more opaque than L1.

About the Speaker:

Say Young is a postdoctoral fellow working with Drs. Winston Goh and Melvin Yap. He completed his PhD at the University of Maryland, College Park (USA). In his graduate and post-doctoral careers, he has conducted several lines of research regarding language processing and second language learning using both behavioral and neuroscience methodology (fMRI and ERPs).

New book by A/P Konstadina Griva “Caregiving in the Illness Context”

9781137558978.indd

A/P Konstadina Griva’s book “Caregiving in the Illness Context”, which she co-authored with international colleagues,  has just been published by Palgrave Pivot. A description of the book is provided below; click on this link for more details.

With more and more people of all ages living with chronic illnesses, greater numbers of family and friends become caregivers. A major focus of health professionals and scientists is to maximize quality of life among those living with illness and those caring for them. As health care systems around the world become limited in what people can afford, informal supports – primarily family and close friends – are being called on to care for ill people. Yet, the task of providing care takes a toll on caregivers’ health and well-being, including depression, social and family strains, increased physical illness, and diminished quality of life. Caregiving in the Illness Context synthesizes current research and brings attention to how personal, social and structural factors affect caregivers and how the research literature has informed emerging interventions to help caregivers.

Title: Embodiment in judgment and decision making: Of fishy smells, dirty hands, and sticky luck

Date: Thursday October 29, 12-1 pm

Venue: AS4/02-08 (Psychology Department Meeting Room)

Abstract:

Recent psychological research shows that complex cognitive processes are grounded in evolutionarily older sensory processes in ways that are often reflected in metaphors. As a result, incidental sensory experiences can profoundly affect judgment and decision making. For example, incidental fishy smells can undermine trust, reduce investment in economic cooperation games, and improve critical reasoning; conversely, socially induced suspicion enhances the sensory perception of fishy smells. Moral transgressions leave a “dirty” feeling and induce a desire to clean; conversely, physical cleansings can remove traces of the past, metaphorically “wiping the slate clean”. Cleaning one’s hands with an antiseptic wipe (but not a moisturizing wipe) can metaphorically remove those traces, resulting in less doubt about past decisions; reduced cognitive dissonance; less influence of recent streaks of good or bad luck on current risk taking; and a reduced impact of sunk cost. I review select findings from my lab and discuss their implications for the conceptualization of decision processes.

About the Speaker:

Professor Norbert Schwarz is Provost Professor of Psychology and Marketing at University of Southern California. His research explores how people make sense of the world in which they live and how their decisions are shaped by subtle contextual influences. His theoretical approach emphasizes the socially situated and embodied nature of cognition and the role of feelings and subjective experiences in judgment and decision making, in different domains, including public opinion, consumer behavior, well-being, and the psychology of self-report. He has won numerous awards in an outstanding career that spans more than three decades, including the Heinz Maier-Leibnitz Prize of the German Department of Science and Education for early career contributions; the Wilhelm Wundt-William James Award of the American Psychological Foundation and European Federation of Psychologists’ Associations; the Distinguished Scientific Achievement Award of the Society for Consumer Psychology; and the Donald T. Campbell Award of the Society for Personality and Social Psychology. His publications include 20 books and some 400 journal articles and chapters, which have been cited more than 52,000 times (H = 105, Google Scholar, June 2015).
