Top 10 Foundational Statistics Vids for Psychology Students

Statistics is a learning hurdle for many of us. I failed the first two years of studying the topic; felt way out of my depth and unable to relate to the concepts. Lately, browsing my Twitter stream, it appears that many other psychology students have similar experiences. So, I have put together my fav Top 10 Foundationals Statistics Vids for you to review your learnt materials and to consider ways to put it into practice in your daily life.

By third year psych I was much more comfortable with the topic os stats in psychology. After 4th year, as a post-grad I took on a TA position at my local uni to tutor 3rd year statistics and research methods. In my second year of taking the subject every student passed the final exam across both tutorial classes. And feedback from the students was all positive, letting me know that they had found a way to have fun with the topic and that they finally ‘got it’.

Unfortunatly a couple of other’s on teaching staff were unhappy that all passed the standardised exam, somthing about funding.

Interesting huh? Anyway, you can read my critique of such a non learning-centred pedagody elsewhere on my blog.

Today I have collated my fav foundational stats vids because I realised that most of the understanding of statistics was grounded in these basics. To this day I continue to do online quizzes to review and extend my learning about the foundational stuff.

Highly recommended for you, thus the list below. Enjoy!

Brief Research Method Critique: Public Art Plan Evaluation Strategy

Cairns Regional Councils’ Public Art Plan (2012-2017) draft is on the web for my local community to puruse and comment upon. I signed up to the Your Say: Help shape the future of our region to do exactly that, contribute to our communiy’s growth and development.

You can review the Plan’s Evaluation Strategy here.

Following, I have provided a brief critique of the Strategy. I hope it enables you to read the research methods in journals and text books with a more critical eye. I have not gone into details as to why I propose certain suggestions~ that’s your homework ~:-) Let me know how it goes for you and what you have to add to my critique.

Research Method Critique

Not very comprehensive is it ~:-) Great that it will cover the areas identified as important. Also I like the multi-method approach for data collection, combining quantitative and qualitative methods. But this is not a strategy, it’s a concept.

Will it be data-collection be in English only?

Will the survey include Likert scales? How many items? How sensitive? What about the wording?

If scales, will they use visual indicators to allow the illiterate and visual-based cultures to be able to answer?

Will there be a pilot test?

What kind of demographic information will be collected?

Will an open-answer section be provided to allow a qualitative element to the survey?

If participants are asked if they would like to be contacted regarding a prize/other incentive/further info, will this info be recorded separatly to provide anonymity and confidentiality to the survey responses they have provided?

How will interviewees be recruited? Is the interview schedule to be structured or semi-structured?

What will the case study involve? More details wanted!

Reading a comment today by a fellow Cairns-ite, it was clear that I had missed a glaring fact~ The draft Evaluation Strategy is not inclusive of community participants, it is an outline for a cost-benefits analysis within the Planning group itself.  I had assumed it was how the public would be engaged with to determine the success of the projects.

So, to add to my comment, with regards to evaluation with a non-public sample:

Who will be surveyed ? (Ditto all the construction commentary I made above)

How will participants be selected? (e.g., randomly? stratified sample across roles?)

Will the evaluations be done by an independent evaluation team?

What do you think of the proposed Evaluation Strategy?

Badges to Motivate Life Long Learning (LLL)

Psychology Tutor:Mentor (PSI) adopted a badges for learning program late last year. I installed at the footer of my blog (see below~ log in with Facebook!) and am learning how to use it to encourage interaction with the site. Throughout the year I will be indroducing other learning badges, to complement student studies and learning in psychology.

There will even be badges you can award to me ~:-) to rate my delivery of services.

Learning badges are one way to create immersive, interactive and rewarding learning experiences for students of all ages and disciplines.

At the moment there is a Badge Comp on, run by Mozilla, Badges Competition: Badges For Lifelong Learning (Awards $10,000 -$200, 000). If you enjoy design for digital media you may like to take part. Here is a schematic of the comp, due date for applications in January 17, 2012.

Stage 2 of the Teacher Mastery and Feedback Badge Competition will be opening soon, check out the site if you are interested in designing badges which reflect the subject and content matter for the learning and feedback of teachers (Awards $10,000 -$200, 000).


Undergrad Student Resource: SnapIt 3.7 screen shot tool

Lucky me has been invited to trail SnapIt 3.7 Screen Capture Software. Yes, I do receive something for the review~ a free copy of the software. My review is an honest reflection of my use of SnapIt.

SnapIt Screen Capture

I highly recommend the SnapIT tool for psychology students (any higher ed student actually). It is really useful to capture images whilst researching on the net, especially form pdfs that don’t allow you to copy sections, you know the ones, where the WHOLE document gets copied! And for saving images such as graphs, logos, symbols or maps that you can use in class presentations or in an essay/report Appendix.

And it’s great to help make your data collection much easier when you need to use screen shots~just remember to cite your sources.

You can also snag and grab screenshots of photos on your ocmputer, saving you time having to upload them elsewhere and linking to a blog or discussion forum.

Capture anything you see on your PC screen! Don’t waste time cropping your captures. Take a “snapshot” of anything exactly what you need, with just a click.

SnapIt is also an irreplaceable tool for Bloggers, Designers, Office Workers, Business People, Analysts, Technical Writers who have to describe interfaces, menus, buttons, etc.

SnapIt  Features

* Supports hotkeys, auto-saving, clipboard

* Automatically copies screenshots to the clipboard

* Tracks capture history, auto-saves captured images

* Saves files in BMP, GIF, JPEG, PNG and TIFF formats

* Auto-names captured images

Comparison with what I already Use

My current screen shot tool is the freeware Gimp. This lil product has served me well, but it has drawbacks. I need to minimize my windows to load it, wait for it to open and then move it out of the way to get the image I want. As you know, a few minutes here and there adds up.

I found having the icon in my toolbar at the bottom of the screen much more convenient. All I do is click ‘Prt Scr’ (Print Screen), a button on my keyboard and the image automatically saves to my chosen folder.

And I found I had more flexibility in choosing what part of the screen to save as I did not have to grab an entire window.

Here is a snapshot of my Desktop:

Try the 14 day trial version of SnapIt here.

The drawback of the software is that it does not have the diversity of cropping options that Gimp offers. However, as I only need basic cropping as an option, this will do me fine ~:-)

You too can access this giveaway by writing a review post/forum/twitter/facebook, etc., contact with link to the review and she will issue you a registration code and name for the trialed software.

And you don’t have to download or reinstall this product again. This license releases all restrictions

Detecting Deception: Appying cognitive psychology learning in the real-world~ kinda


Today’s topics of interest is in the realm of Cognitive psychology and provides examples for a journal critique using the paper, Detecting Concealed Information about Person Recognition (Leal et al., 2011 [Abstract]).

Example of a Journal Critique in Cognitive Psychology

Literature Review

The reader is not given a critical analysis of current literature in this field to determine the gaps in current understanding or methods of deception investigation. As a result, it is not clear how the Leal and colleagues developed the hypothesis and research design used and, it could be, that they are ‘re-inventing the wheel’ or ignoring finding of previous experiments in this field.


Most people lie in daily life (Lying in Everyday Life). However,  can the military and police being asked to lie about details of a friend, be compared to the spontaneous lies of Resistance fighters in WW II who aim to save the lives of their comrades in arms? Or to that of criminals seeking to avoid arrest and or jail time?

Resistance fighters and criminals would have a lot of practice in lying, especially under pressure as it is required for thier survival.

Further, Leal et al. justified their choice of participants as those being, “better able to understand the practical significance of the research and therefore would be highly motivated” (p. 373). An alternative explanation for the results of the study could be that the experience of the officers lead them to mimic behaviours they believeed indicated deception,  thus providing socially desirable responses (demand characteristics).

Sampling for this type of study could be strengthened by recruiting actual criminals (or Resistance fighters)  such as in the study, Assessment Criteria Indicative of Deception (ACID): Replication and Gender Differences. Additionally, stratifying the sample by crime committed (e.g.,not paying parking fines vs. bank robbery) and length of time in jail could control for these confounding variables (e.g., 3 months vs. career criminal).

Stratification by gender would be important too I think, this study was skewed with regards to males (n = 28) with only three female participants. Lying does appear to be more socially acceptable for males and there is literature to support it being more prevelant amongst males (see Children’s Persistent Lying, Gender Differences and Disruptive Behaviours: A longitudinal perspective , Gender Differences in Deception, Nonverbal Deception Abilities and Adolescents’ Social Competence: Adolescents with higher social skills are better liars and Serious Lies).


Operationalisation of the dependant variable  “the appearance of having to think hard” was not adequate. For example, a list of cues to indicate a person as thinking hard and the reliability of such a DV was not provided. Nor waws there any indication that the two raters were trained as to what cues to look for. An inter-rater reliablity of . 56  is acknowledged by the resaerchers to not be high (see p. 374) and, depsite this being on par with other deception inter-rater reliability scores, does not give a reliable operationalisation of this variable.

Hence, it can be argued that measurement was not standardised and so not reliable or valid.


Rather than sending participants on a ‘Secret James Bond Mission’ it would have been better to design the study to provide real-world opportunities for lying. This would require some deception on the part of the researcher, which is not unusual in psychology experiements.


The analysis appears appropriate as multi-dependant variables were used, “occurance of gaze” and “appearance to think hard” that were interval levals of measurement. And the independant variable (IV) was correctly, a nominal level of measurement.


Althought the results were linked to other literature, most of it had not appeared in the literature review for this study. Further, no discussions about limitations of this study were provided. However, the researchers did make recommendations for future resarch and indicated the  usefulness of this study in the field of deception.

PASW Shares~ Enabling the psychology student-centred learning experience

Image: Using SPSS and PASW

Part of my role as a private psychology Tutor:Mentor is providing students with PASW (previously SPSS) resources to enable self-learning. The key to understanding statistics,  is to put it into practice in your daily life. Keep a learning journal, a ‘learning shoebox’ of accumulated notes or simply jot messages onto your mobile phone~ as long as you are collecting data relevant to your life. These practices are the hub of my tutoring and mentoring professioanl development.

Use this data to practice navigating PASW spreadsheets, to become familiar with research design and methods of data collection and analysis that suit your research question. For example, plot your weekly exercise~ weather you are a dedicated gym-bo or simply, like me, make lifestyle choices that enable physical activity (daily chores ~:-), riding a push bike instead of driving a car and walking/running my dogs).

You can download a trial version of PASW v. 19 here, or purchase a student copy (in Australia) from The Co-Op Bookshop Online.

To become more familiar with PASW itself, I highly recommend drawing on resources readily available on the internet. I have listed a few gems below.

AP Psychology Exam Prep: The history of psych helps to guide our future as a science

I thought today for the AP Psychology Exam Prep post that I would upload a qirky vid created by Dr Larry Pfaff of Spring Arbor University. It covers the reasoning behind why we as psychologists need to know our past~ basically, so we can navigate our future.

The video touches on some key points to help understand why it is important to explore the roots of our scientific discipline. I think that writing a summary review of the clip, as I am doing here, is one way to critically reflect on the message of the video and to put it into perspective with my own thoughts. This process, as you can imagine, is a great way to practice writing an open-answer essay question, which in turn, is a fantastic way to organise one’s knowledge on a topic and to identify gaps in understanding or to raise challenging quesitons about how to apply what one knows at this point in time, about the history of psychology.

Personally, I found the argument that most uni/colleges offer a course in the hisotyr of psych a weak argument to justify its inclusion in curriculum. However, having not recevied such a course when I was an undergrad, I can see how a chunk of information was left out of my education that would have helped me to link theories with research methods and applications in daily life.

I liked how the Professor in the clip pointed to wider socio-cultural events in the development of schools of thought in psychology across time; it is critical that we not forget that we are all embeded in our culture of the time and that social values and technology as well as the economic and physical environment, all play a part in how we interpret the world we live in and come up with explanations for it.

The robotic nature of the characters and their voices was a little distracting, but I am keen to try the software myself to see how I can tailor it for enhanving the learning of undergards in psych.

The video points out that psychology grew from two other sciences, physiology and philosophy, and this to me is something amazing about our history. These two scientific disciplines are like the extremes of a continuum, one grounded in the physical and observable the other quite ephemeral and intangible, yet so so useful in aiding one to navigate the world as a critical thinker.

I think that is what I find the most exciting and liberating about studying psychology as a life long learner (LLL); the fact that I can continually use my mind to create the change in my world that I want to see, and that mind-body-spirit overlap and interact to enable and empower me to be the best that I can be, to be the person that I want to be.

Now that I have graduated and am  an online Tutor:Mentor for psychology, I get to indulge my curiousness about psychology through helping undergraduates achieve their academic, career and personal goals. I see great value in learning about our history in psychology, like most learning it is an ongoing process. Understanding the schools of thought within our science is eye-opening in that it makes sense how theoriests chose to investgiate their theories. It gives me insight as to how I can create my own theoires about life, my being, my studies and career and how I can test them,  share them and contribute to this global community in a positive and meaningful way.

What did you think of the video? How relevant do you think the history of psychology to be, to your academic goals?
