Preference And Perceived Danger In Field/Forest Settings, Thomas R. Herzog, Glenn E. Kutzli
Preference And Perceived Danger In Field/Forest Settings, Thomas R. Herzog, Glenn E. Kutzli
Peer Reviewed Articles
The authors investigated preference, perceived danger, and fear for a sample of 70 field/forest settings. Predictor variables included perception-based variables (visual access, penetration,movement ease), information-based variables (mystery, concealment, refuge), and variables thought to intervene between concealment and danger (entrapment, rearview concern). All variables were rated by independent groups. Danger and fear were strongly positively correlated for these settings, but preference and danger had a more modest negative correlation. Factor analysis of the strongly inter-correlated predictor variables yielded two factors, interpreted as Visibility and Locomotor Access. Both factors were positive predictors of preference and negative predictors of danger. Further analyses suggested …

Coefficient alpha is a widely used and useful index of reliability, but it provides an inappropriate estimate of reliability when used with multidimensional composites. The problematic nature of this inappropriate usage varies primarily as a function of the prominence of distinct factors in a composite and to a lesser extent as a function of the length of the measure. Implications for use of coefficient alpha estimates of reliability as the basis for correcting observed correlations for unreliability are described for a variety of levels of multidimensionality and measure length. Researchers should correct for unreliability to estimate construct interrelationships but must …
