Hmm... I really do not know exactly what you are interested in knowing. Anyway, these are just some questions which ppl ask me & I think may help you in some way or another.
1. What are the career prospects?
It depends on your area of interest. There are many fields of psychology, e.g. developmental, organizational, sports, clinical, forensic, just to name a few.
2. With a Bachelors (3 yrs) or Honors (4 yrs) in Psy., what can I do?
Hmm.. Sad to say, alot of ppl have the delusion that with 3-4yrs in psychology, you are called "Psychologists" or you're able to practice (i.e. counsel ppl etc.). Please note, you are NOT called a psychologist with a 3-4yrs of study and you are NOT qualified to practice. 3-4yrs of study is merely a stepping stone into this field. It it not until you complete your Masters (another 2 yrs) that you will be qualified to start practicing and be called a 'psychologist'. It is only during your Masters that you start specializing in a particular field of psychology, e.g. developmental, clinical, counselling etc. Therefore, with a Bachelors or Honors in the field, you start small (really small)....
3. What is the difference between Psychologist & Psychiatrist?
They are VERY different.. Psychiatrist tend to focus on medication approach of treatment. Psychologists, on the other hand, tend to focus on behavioural/cognitive therapy, counselling etc.
Like what some have already replied, Psychology is a field in which you HAVE to work with people. It does help greatly if you have a flair for writing. However, I personally feel that you do not have to "die die must write well", in order to major in psychology. It is not a course which you are able to absorb all the information and regurgitate during your exams. Alot of critical thinking is required and this is something, unfortunately, S'porean students do not tend to fair well in.
To tell you abit more about myself.. I graduated with an Honors equivalent in Psychology and I plan to start my Masters-cum-Doctorate in Clinical Psychology in Nov '07. I am currently working in the research line. Like I said, all 3rd/4th yr Psy. graduates have to start somewhere (and usually, it's quite low on the career ladder of psy.).
At the moment, Singapore Psychological Society (SPS) does not have alot of "power" in SG, unlike the Australian Psychological Society (APS) or American Psychological Society (APA). For APS & APA, you will need a minimum of Masters in Psy., in order to call yourself a 'Psychologist'. However, SPS does not have that type of 'power' in SG yet. That's why when you look through the employment ads in SG, they need ""Psychologists"" with a Bachelors and preferably, a good Honours. For APS & APA, you are required to register yourself with the organization before you are able to practice. It is their way of standardization in this field (i.e. won't let any Tom-Dick-&-Harry to be in a position to be handling clients/patients).
I hope I did not overwhelm you with my response.
