i NEED HELP IN THIS ASSIGNMENT BEFORE ONE HOUR!!!;Question 1;The primary concern of an institutional review board is to;determine whether deception is necessary.;determine whether informed consent will be obtained.;ensure that the safety of research participants is adequately protected.;evaluate the scientific merit of a proposed study.;3 points;Question 2;Tammy?s experiment compared the effectiveness of videotape and textbook presentation of a history lesson. Unexpectedly, her demeanor changed with each treatment condition. She appeared worried during the videotape condition because the audiovisual equipment periodically broke down. In contrast, she seemed relaxed in the textbook condition during which subjects read from a book. Which problem does this illustrate?;confounding by a context variable;experimenter bias;history threat;selection threat;3 points;Question 3;Professor Smith?s class was stunned. She mistakenly included questions from chapter 5 on an exam that was supposed to cover chapters 1-4. In appealing their low grades, the students should diplomatically question the ____of this exam.;construct validity;content validity;face validity;predictive validity;3 points;Question 4;Pavlov?s classical conditioning research contained an element of serendipity because Pavlov;did not recognize the importance of what he found.;discovered this learning process through intuition.;intended to study stomach secretions.;predicted this form of conditioning based on prior research.;3 points;Question 5;Laboratory experiments may trade _____ for precision.;control;generalizability;realism;both generalizability and realism;3 points;Question 6;To study the possible causal relationship between smoking and lung cancer, researchers start with human _____ studies and then progress to animal _____ studies.;experimental, experimental;experimental, quasi-experimental;quasi-experimental, experimental;correlational, quasi-experimental;3 points;Question 7;Which of these should be controlled using constancy of conditions instead of elimination?;a poster for a controversial speaker;bright room lighting;interruptions by students opening the door;visual distractions by classmates outside of the room;3 points;Question 8;In a true experiment, an experimenter ____ the independent variable and ____ the dependent variable.;manipulates, measures;selects, manipulates;measures, manipulates;selects, measures;3 points;Question 9;Theories are explanations of events that;apply to all situations;are supported by a majority of studies;provide interim explanations;are supported by a majority of studies and provide interim explanations;3 points;Question 10;What does a double-blind experiment control?;demand characteristics;experimenter bias;confounding by context variables;demand characteristics and experimenter bias;3 points;Question 11;A _____ is a statistical review procedure that summarizes and quantifies multiple research findings on an individual topic.;case study;factor analytical study;literature search;meta-analysis;3 points;Question 12;Which human experiment could not be justified, regardless of the knowledge that might be gained?;studying the effectiveness of subliminal advertising on product recognition;studying the effectiveness of a drug that produces complete muscular paralysis in treating alcohol addiction;studying the effect of mild sleep deprivation on cognitive performance;studying the effect of shift rotation schedules on employee absenteeism;3 points;Question 13;Since Tim belongs to a Bible study group, a classmate mistakenly assumes that he doesn?t drink alcoholic beverages and always votes Republican. This example of nonscientific inference illustrates;confirmatory bia;overconfidence bias;stereotyping;the gambler's fallacy;3 points;Question 14;is the primary resource currently used by psychologists to find journal articles.;FirstSearch;Lexis/Nexis;PsychINFO;PsychSource;3 points;Question 15;Falsifiable means that a hypothesis is;always false.;capable of being disproved.;fruitful.;parsimonious.;3 points;Question 16;Which of these must be established by institutions engaging in research with human subjects?;human research review committee;institutional animal care and use committee;institutional review board;subjects use committee;3 points;Question 17;Balancing is a control procedure that;distributes the effect of physical variables equally across the treatment conditions.;distributes the effect of the independent variable equally across all of the treatment conditions.;ensures that subjects in all conditions experience nearly identical physical variables.;removes potentially confounding physical variables from the testing situation.;3 points;Question 18;When an experimenter fails to randomly assign subjects to different experimental conditions, a ____ threat is present since treatment groups may differ on subject variables.;selection;statistical regression;subject mortality;testing;3 points;Question 19;An experimenter provided two groups of rats different quantities of food for successfully completing the same maze. She controlled the kind of food and the amount of time the rats had access to the food. She reported that both groups of rats committed the same number of errors in learning the maze. The number of errors was;a confounding variable.;a subject variable.;the dependent variable.;the independent variable.;3 points;Question 20;Which of these techniques to control demand characteristics involves deception?;cover story;double-blind experiment;quasi-experiment;single-blind experiment;3 points;Question 21;Systematic data gathering, noting relationships, and offering explanations are central to;commonsense psychology;the content of science;nonscientific inference;the process of science;3 points;Question 22;In a pretest/posttest design, participants may improve with repeated testing due to increased familiarity with a test. This problem is called;bidirectional causation;practice effect;regression to the mean;a third variable problem;3 points;Question 23;Volunteer subjects may differ from nonvolunteers in that volunteers may be;less authoritarian.;more politically and socially liberal.;more intelligent.;all of these;3 points;Question 24;Researchers conduct experiments in laboratories to achieve the greatest degree of;control;objectivity;generalizability;realism;3 points;Question 25;Experimenters generally want subjects to be as na?ve as possible concerning the experimental hypothesis to reduce confounding by;context variable.;demand characteristics.;experimenter bias.;response sets.;3 points;Question 26;A review of prior studies in an area may provide;help in identifying important issues.;information on previous important issues.;new research ideas.;all of these;3 points;Question 27;In single-blind experiments;experimenters are unaware of the treatments given to subjects.;experimenters encourage subjects to guess the experimental hypothesis.;subjects do not know which treatment they are receiving.;subjects do not receive feedback on their performance.;3 points;Question 28;Kirk hypothesizes that his dog dreams in color. This is not an experimental hypothesis because it;cannot be stated in an "if...them" format.;cannot be tested.;in an analytic statement.;is not a parsimonious statement;3 points;Question 29;Both correlational designs and quasi-experiments are often higher in ____ than laboratory experiments.;external validity;imposition of units;internal validity;manipulation of antecedents;3 points;Question 30;Which of these correlations would permit the most accurate prediction?;-0.93;-0.20;+0.81;+1.32;3 points;Question 31;A longitudinal study that observes first-born children?s behavior before and after the birth of a sibling is particularly vulnerable to a ____ threat since rapid cognitive and physical change normally occur at this age.;history;maturation;selection;testing;3 points;Question 32;In experiments, researchers most often achieve control over possible explanations by;random assignment of subjects to different treatment conditions or use of within-subjects designs.;presenting a treatment condition in an identical manner to all subjects.;keeping the environment, the procedures, and the measuring instruments constant for all subjects in the experiment.;using all of these methods.;3 points;Question 33;Researchers conduct experiments in laboratories to achieve the greatest degree of;control.;objectivity.;generalizability.;realism.;Additional Requirements;Level of Detail: Only answer needed
