A Researcher Shows Pairs of Colour Patches to Canadian University

question 54

Multiple Choice

A researcher shows pairs of colour patches to Canadian university students and members of the Dani culture in Papua,New Guinea.The colour members of each pair are the same or slightly different in hue.Both groups of participants are asked if the members of each colour pair are the same or different.The researcher records the accuracy of all participants' colour discrimination.Which is the dependent variable in this study? What should the researcher find?

• A) Colour discrimination accuracy is the dependent variable. The researcher should find no difference in colour discrimination accuracy between the two groups.
• B) Colour discrimination accuracy is the dependent variable. The researcher should find that colour discrimination accuracy is higher among the Canadian than among the Dani participants.
• C) Participant group is the dependent variable. The researcher should find no difference in colour discrimination accuracy between the two groups.
• D) Participant group is the dependent variable. The researcher should find that colour discrimination accuracy is higher among the Canadian than among the Dani participants.

Definitions:

Resonance Hybrid

A composite representation of a molecule that cannot be depicted accurately by a single structural formula, illustrating electron delocalization.

Aromatic

Describes organic compounds that contain one or more planar rings of atoms with delocalized pi electrons, following Huckel's rule.

Nodal Planes

Imaginary planes in an atom or molecule where the probability of finding an electron is zero, often associated with molecular orbitals.

P Orbitals

Atomic orbitals shaped like dumbbells, consisting of regions where there's a high probability of finding an electron outside the nucleus, pivotal in chemical bonding and valence.
