Abstract

Long-term retention of vocabulary in two phonetically similar foreign languages is aided when learning occurs in highly distinctive virtual reality environments*

Joey Ka-Yee Essoe, Nicco Reggente, Ai Ohno, Hera Youn-Ji Baek, Jesse Rissman

The environmental context in which a memory is encoded can impact its later accessibility by virtue of tagging the memory with unique retrieval cues. We examined whether distinctive virtual environments (VEs) could be used as a means to provide contextual support during the learning of two sets of easily confusable stimuli. Specifically, we taught participants the translations of 50 English words in two pre-experimentally unfamiliar languages: 10 were learned only in Swahili, 10 only in Chinyanja, and 30 in both languages. Participants in the Dual Context group learned each language in a different VE, whereas participants in the Single Context group learned both languages in the same VE. On Day 2, after the fourth VE learning session, participants’ ability to recall the Swahili and Chinyanja translations of the English words was tested outside of the VEs. One week later (Day 8), participants were reached by telephone and performed a surprise recall test assessing their long-term retention of the foreign words. Our results revealed that while the Single and Dual Context groups showed comparable recall performance when tested on Day 2, the Dual Context group exhibited significantly reduced forgetting when tested on Day 8. This finding showcases how distinctive learning contexts can protect newly acquired memories from succumbing to excessive interference and promote long-term retention. An additional fMRI dataset collected from a separate group of Dual Context participants during Day 2 cued recall should provide further insights into the mechanisms that underlie their memory advantage.

A Children’s Sunday School Story: Charlotte Elliott (She of “The Invalid’s Hymn Book”)

I prepared this lesson for University Bible Church, Los Angeles, CA (Presented on 2015-05-17). This material was Intended for (and was understandable to) children between the age of 6 and 10.

This lesson took 26 minutes, including children’s response (mostly hand-raising, only 2 short questions), and the song in the end.

Image credits are noted in the captions (I did my to the best of trace and credit photographers or artists. Should there be error in the rights of these images, my sincere most apologies, and I welcome your email so I can make corrections).

An Illustrative Guide to Statistical Power, Alpha, Beta, and Critical Values

From my interactions with undergraduate students, it seems that even though these definitions are easy to recite, they are difficult to be integrated into a comprehensive whole. I hope here to show how to conceptually integrate them into a cohesive picture.

This post was originally created for Psychology in Action, and edited by her new blog master, Tawny Tsui. See her posts here.

Everything begins with reality: the “Reality Continuum”

PowerAlpha1I call this green line “Reality Continuum” (rather grand, no?) because you will take your ideas, and do a reality check against it via data analysis (within the traditional statistical framework–it is definitely NOT the only framework on the market, but I digress).

Amazed to learn…

Amazed to learn…

Speechless, I learnt anew of Your love for me.
_____ Yes, You have told me before,
_____ Grace manifested on the Cross.

(Zephaniah 3, Psalm 147, Luke 15)
You opened my eyes; the Cross means so much more!
_____ You rejoice in me;
_____ You delight over me;
_____ You run to me even before I reached for You;
_____ You dance with joy on the day you ordain to bring me home;
_____ You sing (loudly!) over me!

Who? Me?! Wah…

(Luke 15)
When I repented, it is not the angels who danced,
_____ “There is joy before the angels of God.”
_____ Who is before the angels but the Mighty I AM Himself?
You, Yourself, the Dignified Father, dance with joy to reunite with me!

(Ephesians 1)
I am Your inheritance, as You are mine.
_____ You have longed for me, an eternity before I started longing for You.
You see me as righteous, even as I stumble.
_____ You call me child, even as I cover myself with filth.

(Ephesians 1, Romans 8)
You decided. You will make me like Christ.
_____ You cannot be thwarted, despite of me.
You promised. You will make me like Christ.
_____ You cannot fail, despite of me.

On Christ, Anxiety, and Waiting (in Academia)

More than most of us are willing to admit, the life of an academic and scientist consists of much waiting.

Some do this better than others; I am not, by nature, one of them.

Many times I have been weighted down by the anxiety of waiting: for graduate school acceptance letters, for getting a grant for my research, and for graduate research fellowship funding, etc.

It is now the season of waiting to hearing from graduate schools (the tail end of that), fellowship applications, job search for new graduates, etc. It is lent, too, though I am not of the Catholic tradition.

The following is probably the most personal post I have attempted. I will share how the Holy Spirit ministers to me through the Bible in hopes that it would help minister to you in such seasons. Especially for those of you whom Jesus has called to be a missionary in the scientific fields–the prevalence of Christians in these fields could probably qualify them as unreached people groups! (Perhaps with the exception of physics and mathematics by reputation? But I have no stats, and it is neither here or there.)

These are not trite statements, but came both from seasons of waiting that turned out to be “successful” and “unsuccessful.” Amazing that the Spirit gave me the same comfort prior to both. Humbling too, that He has to do this repeatedly for me [chuckle]. I am the “chief of sinners” and still learning this, repeatedly.

Fun Fact: God loves us so much that He made us just in time for the weekend!

On Sabbath and Work: Gen 1:26 to 2:1 

I used to think that since God created on Day 1-6, then rested on Day 7, I am to work and then rest also. For many years, I followed this empty-refill pattern: poured myself out in my work, then recovered on Sabbath day.

When I  re-study Genesis, I was very surprised to see that

       God had set different work-patterns for mankind than for Himself!!
       God loves us so much, he made us just in time to enjoy the first Sabbath.

As loving parents preparing a home for their soon-to-be-born child, He prepared the Earth for us. Then He created us so we can first rest in (first day after the creation of human kind is… SABBATH!) and enjoy Him—which prepared us for the work He had ahead for us.

We are to first rest and fill ourselves with God’s love, grace, blessings, and motivation for work, enjoyed the fruits of His/our labour. This empowers us to empty ourselves for work in following 6 days.

Fill your “gas-tank” before emptying it.
