When evaluating the validity of their new Need for Cognition Scale, what approach did Cacioppo and Petty use to examine its relationship with established variables such as intelligence and dogmatism?

In Cacioppo and Petty's study of the Need for Cognition Scale, they compared their new measure against three established variables to test its validity. Match each variable with the specific theoretical purpose it served in their correlation matrix.

In the correlational approach used by Cacioppo and Petty to validate the Need for Cognition Scale, if the correlation matrix had revealed a very high positive correlation (e.g., r = .85) between the new scale and socially desirable responding, this result would have supported the scale's validity.

Researchers validating the Need for Cognition Scale used a correlation matrix to analyze how the new measure related to existing constructs. Based on the theoretical predictions for construct validity, arrange the following comparison variables in order from the one expected to have the most positive correlation with the scale to the one expected to have the most negative correlation.

To evaluate the validity of their 'Need for Cognition Scale', Cacioppo and Petty compared participants' scores against which three established variables using a correlation matrix?

Cacioppo and Petty used a complex correlational approach to assess the validity of their new 'Need for Cognition Scale'. Arrange the steps of this validation process in the correct logical order.

If the correlation matrix for the Need for Cognition Scale revealed that the measure correlated $r = .80$ with socially desirable responding and only $r = .05$ with intelligence, a researcher would be forced to _____ the claim that the scale has construct validity.

A research team develops a new scale to measure 'Cognitive Curiosity'—defined as the desire to explore new ideas. They compare scores on the new scale with three established variables using a correlation matrix and find that the overall pattern of correlations closely matches their theoretical predictions about how Cognitive Curiosity should relate to those variables. Applying the same logic Cacioppo and Petty used when validating the Need for Cognition Scale, this result would support the validity of the new Cognitive Curiosity Scale.

In Cacioppo and Petty's validation study, the Need for Cognition Scale was compared with three established variables. Analyze the theoretical reasoning behind each comparison and match each variable or concept to the predicted role it plays in the correlation pattern.

A researcher develops a 'Reflective Thinking Scale' and validates it by computing a correlation matrix with the same three comparison variables Cacioppo and Petty used: intelligence ($r = .52$), socially desirable responding ($r = .07$), and dogmatism ($r = -.40$). Because this pattern of correlations _____ the theoretical predictions for how reflective thinking should relate to these constructs, a methodologist would conclude that this evidence supports the scale's construct validity.

In their validation of the Need for Cognition Scale, John Cacioppo and Richard Petty (1982) compared participants' scores against three other established variables. Identify these three established variables and recall the definition of 'socially desirable responding' as described in their study context.

Based on the concept of establishing validity via a correlation matrix, explain how the researchers should interpret the pattern of correlations. Specifically, describe what pattern of correlations with GPA, test anxiety, and socially desirable responding would support the validity of their new Academic Motivation scale and explain why.

Suppose you are developing a new scale called the 'Skepticism Index' to measure scientific literacy. Apply Cacioppo and Petty's correlation matrix approach by identifying two distinct, established variables you would measure alongside your index to validate it, and state the predicted direction (positive, negative, or near-zero Pearson's $r$) for each.
