31)An example of a response-inferred organismic variable is A)a participant’s weight. B)a participant’s race. C)the amount of weight a participant loses in an 8-week weight loss study. D)a participant’s attitude toward obesity. 32)An example of a response-inferred organismic variable is A)a participant’s weight. B)a participant’s performance on an arithmetic test. C)a participant’s speed in completing a task. D)a participant’s anxiety during math exams. 33)In experimental research, the variable designated as the independent variable A)refers to the variable that is directly manipulated by the research team. B)refers to the variable that is directly manipulated by the participant. C)refers to a variable that is independent of any measurement strategy. D)refers to the variable that is not directly manipulated. 34)Which variable can be directly manipulated by the experimenter? A)The response-inferred variable. B)The organismic variable. C)The independent variable. D)The dependent variable. 35)Characteristics of participants, such as age and sex, are called A)organismic variables. B)stimulus variables. C)response variables. D)dependent variables. 36)A constant is A)the direct opposite of a variable. B)not a variable. C)a specific number, as in mathematics. D)a variable that does not vary. 37)If age and gender caused variability in response to a particular pharmaceutical drug in elderly people, and we only test 70-year-old females, age and gender would be A)manipulated independent variables. B)constants. C)manipulated dependent variables. D)nonmanipulated independent variables. 38)A researcher hypothesizes that criticism and aggression increase among coworkers when frustration increases. Workers are assigned to one of three groups (no frustration, moderate frustration, no frustration). For each group, verbal criticism and aggression are measured. In this example the independent variable is  A)frustration level. B)verbal criticism and aggression. C)number of people in a group. D)amount of work completed. 39)A researcher hypothesizes that verbal criticism and aggression among coworkers increase as frustration increases. Workers are assigned to one of three groups (no frustration, moderate frustration, high frustration). For each group verbal aggression and criticism are measured. In this example the dependent variable is A)frustration level. B)verbal aggression and criticism. C)the number of people in a group. D)amount of work completed. 40)In a study with organismic independent variables, A)causal conclusions are very strong. B)no conclusions can be drawn. C)any causal conclusions must be tentative. D)active manipulation of the independent variable must be included. Â
