There are many individuals who view punishment (both positive and negative) as a necessary teaching method. This can vary from one culture to another as well as from one individual to the next. What are your views on using punishment in order to reduce unwanted behaviors? In what situations is it OK, and in what situations should it be discouraged? Provide examples and references, if appropriate.

Reflect on these questions. What can you do at this stage of your life? How can you be responsible in your life? The following prompts can guide you.

I learned that I can ….

With the abilities I have, I will be responsible for ….

To improve myself, I realized that I should develop

In Gray’s theory of reinforcement sensitivity

Another part of this model has to do with one’s behaviour being inhibited. Specifically, people whose Behavioural Inhibition System (BIS) is highly sensitive tend to worry more and take the safer approach to things. People with a low BIS are more likely to be risk-takers and to act more impulsively. Behavioural inhibition has been linked to Neuroticism in the trait model of personality.

Do the trait facets listed within Neuroticism seem to fit well with the characteristics of someone who displays high behavioural inhibition (that is, someone who is very cautious)? Why or why not?

Looking at the other side of the equation, what personality traits seem like they would describe someone who is low in behavioural inhibition?

In Gray’s theory of reinforcement sensitivity, the Behavioural Activation System (BAS) is linked to novelty-seeking and adventurousness. In other words, some people are motivated by opportunities to seek out new experiences and are more inclined to make or agree to spur of the moment decisions.

Researchers have found that overall, people who have a highly sensitive BAS tend to be more extraverted (i.e., they are more outgoing and are more energized by social situations). 

• Using purely anecdotal data, can you think of any examples of people who fit this description well (i.e., being both extraverted and exhibiting characteristics associated with a high BAS)? You don’t need to name anyone or say how you know them; just a general description is fine. 
  
• Can you think of anyone who doesn’t fit this description (e.g., someone who is shy but who likes to travel to new places on their own in order to seek out new experiences, someone who is very outgoing and sociable but is still a bit reluctant to try something new)?

The mean Verbal SAT score for the population of first students at Radford is 520. The

standard deviation of scores in this population is 95. An investigator believes that the mean

Verbal SAT of first year psychology majors is significantly different from the mean score of the

population. The mean of a sample of 36 first year psychology majors is 548. Test the

investigator's prediction using an alpha level of .05.

The following are the pre and post test scores of 10 pupils before and after having

given remedial teaching and learning activities in Mathematics:

Pre-test: 75, 50, 46, 62, 57, 54, 39, 49, 52 and 36

Post-test: 85, 70, 66, 71, 80, 81, 68, 60, 81 and 58.

Did the group make a significant gain as a result of the activity? Use 0.01 level of significance in

testing the hypothesis.

On the basis of her experience with clients, a clinical psychologist thinks that depression may

affect sleep. She decides to test this idea. The sleep of nine depressed patients and eight

normal controls are monitored for three successive nights. The average number of hours slept

by each subject during the last two nights is shown in the following table:

Hours of Sleep

Depressed Patients Normal Controls

7.1 8.2

6.8 7.5

6.7 7.7

7.3 7.8

7.5 8.0

6.2 7.4

6.9 7.3

6.5 6.5
