![]() ![]() Thus a navigator must be able to move freely to map extended cues only then should the weighted hierarchy of available navigation mechanisms shift in favor of the integrated map. To create a bearing map (and hence integrated map) from extended cues requires self-movement over a large enough space to sample and model these cues at a high resolution. Moreover, this has implications for the lab. We propose that the dual navigational mechanisms of pigeons, the navigational map and the familiar area map, could be homologous to these mammalian parallel maps this has implications for both research paradigms. Here the cognitive map is redefined as the integrated map, which is a construction of dual mechanisms, one based on directional cues (bearing map) and the other on positional cues (sketch map). To reconcile this and other debates within the field of navigation, we return to the concept of the parallel map theory, derived from data on hippocampal function in laboratory rodents. But the communities of researchers that study the cognitive map in non-humans are strangely divided, with debate over its existence found among behaviorists but not neuroscientists. He will test if turtle eggs incubated at 29-30 degrees Celsius produce females, and eggs at 24-26 degrees Celsius produce males.Space is continuous. What is the dependent variable? mass of mice A zoology student is investigating whether it is true that the gender of turtles depends on the temperature at which the turtle eggs are kept before they hatch. He feeds each group the same amount of food at the same time each day. He measures the mass of the mice each day. Max wants to see if mice that are fed food A grow faster than mice that are fed food B. Does Megan have a control group in this experiment? No, there is no control group because each group is treated under test conditions. She feeds each group the same amount of food at the same time each day. She measures the mass of the mice on day 1, then divides them into two groups based on the type of food they will be given. What is the independent variable in Jamal's experiment? the color of the feeder Megan wants to see if mice that are fed food A or B grow at a faster rate. Jamal asked the question "Are hummingbirds attracted to red feeders?" Then, he set up an experiment to test the question. The photograph below shows Jamal's bird feeder. Which statement best summarizes the factors that need to be controlled in this experiment? all plants should be the same age and health and be given equal amounts of water and sunlight. ![]() She measures the growth of all of the plants in each group for a month. A student wants to answer the question "Does adding calcium powder to soil make pea plants grow faster?" She adds calcium powder to the soil of 12 plants and does not add it to the soil of a second group of 12 plants. Which statement describes the dependent variable? It is also called the manipulated variable. It is also called the responding variable. Which statement describes the independent variable? He would be answering the question "How does increasing the amount of vinegar affect the amount of bubbles that form?" ![]() He would be answering the question "How far will bubbles travel across a flat surface?" -He could add different amounts of vinegar to the same amount of baking soda and time how long it bubbles each time. He would be answering the question "How long will my volcano bubble?" -He could measure how far the bubbles travel across the laboratory table after he pours the vinegar into the baking soda. He would be answering the question "What happens when I pour vinegar into baking soda?" -He could time how long the volcano bubbles after he pours the vinegar into the baking soda. What would be the best way for Tim to turn this demonstration into an experiment? -He could pour the same amount of vinegar into several different volcanoes containing baking soda, repeating the demonstration. He crafts the volcano out of clay, and then pours vinegar into the baking soda that is inside the volcano. Tim makes a volcano demonstration for a class.
