Dr. Kang, a cognitive psychologist, conducts an experiment examining the effect of emotion on memory. He provides lists of 15 wo

rds to two groups of participants at his university. He puts the names of all the participants in a hat. The first 20 names he assigns to Group A and the last 20 he assigns to Group B. Group A is given a list of words that are very emotional in content (e.g., passion, murder). Group B is given a list of words that are neutral in content (e.g., houseplant, desk). He then measures how many words each group is able to remember after being distracted for 5 minutes by watching a video about the history of the university. He finds that Group A remembers 15% more words than Group B. Refer to Research Study 3.4 above to answer the following question. If Dr. Kang decided against using random assignment, which of the following would be threatened? a. The covariance of the study b. The temporal precedence of the study c. The internal validity of the study d. The external validity of the study e. The construct validity of the study

Answer: C

Explanation: The one that would be threatened by using a random assignment is the internal validity of the study.

Internal validity is defined as the grade in which a study can prove relations between the variables; by using a random assignment, there will be variables that weren't taking into consideration and for instance, the internal validity will be lowered.

Answer:

c. The internal validity of the study

Explanation:

The internal validity of a study is the term that refers to the ability of a study to show that it has a practical skill, through how well the results of that study have been established. in other words, this validity refers to a study that presents a good performance, because it was established with a correct design, well-developed variables, well-established results evaluation, among other factors, which show that the study was carried out correctly, so your results can be reliable.

If Dr. Kang decided not to use random assignment, the study's internal validity could be a threat to prove the truth, since we have little information on how the entire study was conducted.

Lana71 [14]

Answer:

The kinds of food the Native Americans ate, the clothing they wore, and the shelters they had depended upon the seasons. Their foods changed with the seasons. In winter, they hunted birds and animals and lived on stored foods from the previous fall. In spring, they hunted, fished and picked berries. In summer, they grew crops (beans, corn, and squash). In fall, they harvested crops and hunted for foods to preserve and keep for the winter.

The Native Americans used natural resources in every aspect of their lives. They used animal skins (deerskin) as clothing. Shelter was made from the material around them (saplings, leaves, small branches, animal fur). Native peoples of the past farmed, hunted, and fished. They used natural resources such as rock, twine, bark, and oyster shell to farm, hunt, and fish.

Explanation:

Hunting and Fishing and Farming: Indian men had the primary tasks of fishing and hunting. Each winter men from different tribes would join together for hunting expeditions. Deer meat, or venison, served as a supplement to the mostly agricultural diet. The Indians used other parts of the deer such as skin for clothing and bones for tools. The men also protected their village.

The Powhatan Indians were primarily farmers planting fields that averaged one hundred acres in size. The women were responsible for working the fields and did so using various tools made from such materials as deer antlers. They grew corn, squash, pumpkins, beans and sunflowers. They also gathered wild foods from the land around them such as nuts, berries and roots. The women were responsible for making meals of these foods. Corn (maize) was the staple crop, and from it women produced such foods as corn cakes and hominy.

Homes: Since the Powhatans were farmers, they did not move around like Indians of the western plains who had to follow the herds of buffalo. As a result, they built semi-permanent houses that were framed with saplings and covered with woven reeds or bark. Constructed by the women, these “yehakin” provided good protection from all the extremes of weather, sometimes for as many as sixteen to twenty members of an extended family. The fire in the center of the lodge was kept burning at all times which kept the house warm and dry.

Clothes: Each tribe had a chief or “werowance” who ruled over the tribe. All the tribal chiefs were subject to Powhatan. They supported him in war and paid an allowance to him from their tribe. Status was determined by achievement, often in warfare, and by the inheritance of luxury goods like copper, shell beads and furs. Those of higher status had larger homes, more wives and elaborate dress.

A person makes a round-trip journey, finishing where she started. The displacement is 0 and the distance is some non-zero value.
Ksju [112]

Answer:TRUE

Explanation: Displacement is a change in position of an object or a person starting from where he or she started or where the object was sent from to the final point. If an object or a person returns to the same point as at the point he or she started the person's displacement is ZERO.

Distance is the term used to describe the length covered, it measures from the starting point to the finish line it is a NON ZERO VALUE. Both DISPLACEMENT AND DISTANCE COVERED ARE SCALAR QUANTITIES.
