A forensic psychologist was interested in the possible effects of several variables on the ability of witnesses to recall information about a crime. Participants viewed one of four 10-minute video clips depicting a crime event. In the video clips, the investigator manipulated the race of the crime perpetrator (same or different from that of the participant) and the type of crime that was committed (violent or nonviolent). After viewing a single video clip, each participant answered a series of questions about the event depicted in the video. The number of questions answered correctly determined the recall score for that participant. What type of design is this study

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.

i took very good i wish you luck! i hope it .
