In a study, injections of saline solution (which contains no chemicals) were shown to be quite effective for relieving pain. this is an example of:
the experimenter effect
a placebo effect
the experimental effect
an order effect
The experimental group is:
Study in which neither the experimenter nor the subjects know if the subjects are in the experimental or control group
study in which the subject do not know if they are in the experimental group or control group
subjects in an experiment who are not subjected to the independent variable and may receive a placebo treatment
the group to which the researchers manipulate the independent variable
The main purpose of ethical guidelines for research in Psychology is to:
minimise the problems that participants cause for researchers
guarantee that the experimentation runs without problems
protect the welfare and rights of the participants
ensure that any results published will not be challenged
Psychology researchers attempt to minimise or eliminate the impact of uncontrolled variables in experiments because the presence of these variables:
do not enable the researcher to control the dependent variable
means that only the uncontrolled variables are measured
make it difficult to isolate and evaluate the impact of the independent variable
can affect the measurement of the independent variable
A double-blind study is:
a study in which the subjects does not know if they are in the experimental or control group
a study in which neither the experimenter nor the subjects know if the subjects are in the experimental or control group
a measure of the relationship between two variables
the observation of human or animal behaviour in its natural setting
in an experiment, DEBRIEFING of participants most likely includes information such as:
each participant's own results in the study
the number of hours participants will be expected to participate
the procedures that will be required fo participants during the experiment
the individual results of the other participants in the study
the experimenter effect might occur when participants in an experiment:
consciously or unconsciously affect the behaviour of the experiments in the experiment
are all tired from participating from experiments throughout the day
alter their behaviour because of conscious or unconscious cues given to them by the researcher
undergo the sam procedures as an experimental group, but do not experience effects of the independent variable.
What is a population?
a sample that has characteristics that are similar to those in the population
subjects in an experiment who are not subjected to the independent variable and may receive a placebo treatment
study in which the subject do not know if they are in the experimental or control group
the entire group if people or animals in which the researcher is interested.
What is a representative sample?
subjects in an experiment who are not subjected to the IV and may receive a placebo treatment
a sample that has characteristics that are similar to those in the population
the entire group of people or animals in which the researcher is interested.
study in which the subject do not know if they are in the experimental or control group
what is the scientific method?
a process of systematic observation, measurement and experiment to formulate and test hypotheses
clear and detailed statement about how you will measure the data collected about the variables
a sample that has characteristics that are similar to those in the population
the group to which the researchers manipulate the IV
In an experiment studying the impact of meditation on stress, the control group should:
meditate more often than the experimntal group
be able to choose whether to meditate or not
meditate as often as the experimental group
not meditate at all
In an experiment, the ____________ variable is tested (manipulated) by the researcher to observe its effect(s) on the _____________ variable.
first; second
independent; dependent
dependent; independent
research; results
A school principal wanted to do some research into general literacy abilities of students from grades 1 to 4 at her school. She divided the students into year levels. She then randomly selected study names out of a hat to participate in her testing. This is an example of what type of sampling?
(a)
A program was run to improve the goal-shooting accuracy of the school's basketball team. A study of the effectiveness of the program was undertaken to determine if it should be used in other schools. A trial run before the program is implemented and the average score for shooters is 52%. The shooters are then randomly divided into 2 groups.
The members of the CONTROL GROUP practise shooting for 1 hour per day, under the supervision of their classroom teacher. The members of the EXPERIMENTAL GROUP undertake the program for 1 hour per day, under the supervision of their basketball coach. After 5 sessions, the test is repeated and the scores recorded.
A potential CONFOUNDING VARIABLE in this study is:
the classroom teacher versus the expertise of the basketball coach
the health of the basketball players before and after the program
the height of the basketball players
the age of each basketballer, and therefore the average age of the group to which they are assigned
what is meant by an operational definition?
a measure of the relationship between two variables
a statement about the IV and DV
clear and detailed statements about how you will measure the data collected about the variables
a statement that reflects the characteristics of the population
An experiment is conducted to determine the effects of a training program, delivered through observation, on the distance perception of pilots.
Two groups of plots are used. GROUP 1 is told they will receive a training program and are shown a TV documentary about flying techniques. GROUP 2 watch a TV program providing the actual observation training.
The participants then complete a series of distance perception exercises and receive a total score for the exercerses.
Write an OPERATIONAL DEPENDENT VARIABLE for this study.
