Hello John,

Just wondering if you are going to make a new spec IA checklist?

Many thanks,

Hello Mr. Crane, my name is Humberto García and I am writing from Lima - Peru. This is my first time I´m teaching psychology in IB and it has been quite challenging. I am advising two students from grade 12 with their Internal Assessment. Both of them have chosen the "Serial Position Effect" for replication and I have been struggling with the selection of participants. Due of convenience of the sampling, we have agreed on using staff school teachers (primary and secondary) as participants. We are going to select (by random) 10 teachers to be part of the control group and 10 teachers for the experimental group. Most of the teachers are fluent in English; however, it is not their native language. I have a few questions: 1. Since the original study was conducted in English, is it possible to replicate it but using the native language of our country? (Spanish). 2. If it is not possible, will we have to select only the teachers who are english native speakers? If so, we are afraid we won´t get the 15 participants required as minimum. 3. If we present the list of words in english to the participants (english native speakers and spanish native speakers), would this affect the results on serial position effect? 4. We have been looking through other replications and we can see that they have presented different list of words (one list was made up with 20 words and others consisted of 14), is there an "original list of words" we can use and where can we find it? Thanks in advance Mr. Crane for your attention to this message. Kind regards. Humberto.

Dear Humberto

Welcome to IB Psychology! Here are the answers to your questions - 1. Yes, of course you could do the studies in Spanish. 3. This gets a bit complicated. If they could all be Spanish speakers or English speakers, that would be best. 4. You do not need to use the original word list. You can make up a word list. This is not a problem. You should probably keep all of the words one syllable words to make sure that the length of the word is not a confounding variable.

Really appreciate your guidance Mr. Crane! I will talk to my students to share with them your ideas. Have a nice day!

Hi John could i please ask your advice on the following question:
"To what extent does the biology of an individual affect the development of antisocial personality disorder?"
Would it be better if she focused on say hormones or brain structures, as 'Biology' may be to broad?

sorry this is in the wrong section, apologies.

Dear Zakeya

It depends on what she finds. The role of biological factors is fine, but if she finds a lot of material on brain damage, for example, then she could focus on the essay solely on that one factor.
