Blakemore and Cooper: Psychology Quiz!

Independent measures design involves using different groups of participants for each condition or treatment being tested. Each group is exposed to only one level of the independent variable. This design allows for comparing the effects of different conditions or treatments across groups, reducing the risk of order effects or carryover effects that can occur in other designs such as repeated measures or matched pairs.

The correct answer is 2 because the question asks for the number of kittens that were anesthetized. The number 2 indicates that there were two kittens that were put under anesthesia.

The independent variable in this study was whether the kittens were reared in a horizontal or vertical environment. This means that the researchers manipulated the environment in which the kittens were raised to see if it had an effect on their development or behavior. The other options mentioned in the question, such as the lighting conditions or the type of glasses worn by the kittens, are not mentioned as independent variables and therefore are not the correct answer.

The researchers prevented the kittens from looking at themselves while in the special apparatus by giving them a collar. This suggests that the collar may have obstructed their view or restricted their movement in a way that prevented them from seeing themselves. Wearing glasses or a hat could also potentially achieve the same result, but the given answer specifically mentions the use of a collar.

The kittens mainly guided themselves by touch. This means that they relied on their sense of touch to navigate and explore their surroundings. Touch is an important sense for kittens as it helps them to feel and understand the objects and surfaces around them. By touching and feeling their environment, the kittens were able to gather information about their surroundings and move around effectively.

The correct answer is "The kittens were taken to a room with tables and chairs. Their visual reactions were observed and recorded/noted." This answer suggests that the dependent variable, which is the visual reactions of the kittens, was measured by observing and recording/noting their reactions in a room with tables and chairs.

The research method used in this case was an experiment. An experiment involves manipulating variables and measuring the effects of those manipulations on other variables. It is a controlled method that allows researchers to establish cause-and-effect relationships between variables. In an experiment, the researcher has control over the independent variable and randomly assigns participants to different conditions or groups to compare their responses. This method is often used to test hypotheses and determine the effects of specific interventions or treatments.

The aim of the investigation was to study the development of the primary visual cortex. This suggests that the researchers were interested in understanding how this specific area of the brain, which is responsible for processing visual information, develops over time. By studying the development of the primary visual cortex, they may gain insights into how visual perception and processing abilities develop in individuals.

The correct answer is "From birth to 1 year". This means that the kittens were studied from the moment they were born until they reached the age of 1 year. The time range does not include any period after the first year.

The correct answer is 10 hours. This suggests that it took the kittens 10 hours to exhibit startling responses and visual placing.

The given answer suggests that brain development is primarily influenced by genetic factors (x) rather than functional factors (y). This means that the development of the brain is more dependent on the individual's genetic makeup rather than the functional aspects of their environment or experiences.

The correct answer is 75%. This means that 75% of the cells in both the cats that were anaesthetised binocular.

The visual field that cats are restricted to is 130. This means that cats have a limited range of vision, and can only see objects within a 130-degree angle in front of them. They are unable to see objects that are behind them or outside of this range.

The kittens were put inside the special apparatus for 24 hours a day. This means that they were kept inside the apparatus all day long without any breaks.
