Rotational kinematics influence multimodal perception of heaviness

Perceived heaviness has been shown to be specific to an object’s rotational inertia (I ), its resistance to rotational acceleration. According to the kinematic specification of dynamics (KSD) principle, we hypothesized that I is optically specified by rotational kinematics. Using virtual depictions of wielded objects, we investigated whether the visually detected rotational kinematics of wielded objects would influence perceived heaviness in a manner consistent with the inertial model of heaviness perception. We scaled the virtual object’s movement so that it rotated more or less than its wielded counterpart, specifying lower and higher I, respectively. Perceived heaviness was inversely related to the rotational scaling factor, consistent with a KSD interpretation of the inertial model.     

B. F. Skinner's Utopian Vision: Behind and Beyond Walden Two

This paper addresses B. F. Skinner's utopian vision for enhancing social justice and human well-being in his 1948 novel, Walden Two. In the first part, we situate the book in its historical, intellectual, and social context of the utopian genre, address critiques of the book's premises and practices, and discuss the fate of intentional communities patterned on the book. The central point here is that Skinner's utopian vision was not any of Walden Two's practices, except one: the use of empirical methods to search for and discover practices that worked. In the second part, we describe practices in Skinner's book that advance social justice and human well-being under the themes of health, wealth, and wisdom, and then show how the subsequent literature in applied behavior analysis supports Skinner's prescience. Applied behavior analysis is a measure of the success of Skinner's utopian vision: to experiment.     

Cultural chameleons and iconoclasts: Assimilation and reactance to cultural cues in biculturals’ expressed personalities as a function of identity conflict

Bicultural individuals vary in the degree to which their two cultural identities are integrated versus conflicting—Bicultural Identity Integration (BII). Past research on attribution biases finds that BII influences the way that biculturals shift in response to cultural primes: integrated biculturals shift assimilatively, whereas conflicted biculturals shift contrastively. Proposing that this reflects assimilation versus reactance responses, we tested whether it extends to shifts in self-perceived personality. In two experiments with Asian-American participants, we found that BII influences the direction of cultural priming effects (assimilation versus contrast) on the personality dimensions of need for uniqueness (Experiment 1) and extraversion (Experiment 2). As hypothesized, high BIIs shifted in a culturally assimilative direction, perceiving the self as more uniqueness-seeking and extraverted following American versus Asian priming, whereas low BIIs shifted in the reverse direction. Implications for research on bicultural identity, priming, personality, organizational and consumer behavior are discussed.     

Repetition blindness: an emergent property of inter-item competition

Repeating an item in a brief or rapid display usually produces faster or more accurate identification of the item (repetition priming), but sometimes produces the opposite effect (repetition blindness). We present a theory of short-term repetition effects, the competition hypothesis, which explains these paradoxical outcomes. The central tenet of the theory is that repetition produces a representation with a higher signal-to-noise ratio but also produces a disadvantage in the representation’s ability to compete with other items for access to awareness. A computational implementation of the competition hypothesis was developed to simulate standard findings in the RB literature and to generate novel predictions which were then tested in three experiments. Results from these experiments suggest that repetition effects emerge from competitive interactions between items and that these influences extend to adjacent, nonrepeated items in the display. The results also present challenges to existing theories of short-term repetition effects.     

The relative importance of needs among traumatized and non-traumatized samples

Typically, people rate enhancement needs as more important than security needs to their well-being. Two studies tested whether event valence and prior trauma moderate relative need importance. Traumatized (hurricane survivors) and non-traumatized (control) participants recalled the most “distressing” (security-relevant) or “satisfying” (enhancement-relevant) event they had recently experienced and rated the importance of 10 needs in defining the event. In both studies, event valence moderated relative need importance on explicit (salience) and implicit (affect) measures as enhancement needs were more important for enhancement-relevant (satisfying) events whereas security needs were more important for security-relevant (distressing) events. However, results also suggest that differences in traumatic experience across samples moderated the effect of event valence on relative need importance. Unlike non-traumatized (control) participants, traumatized (hurricane survivors) participants did not reassign greater importance to enhancement over security needs when event valence shifted to enhancement-relevant (satisfying) memories. We close by discussing implications for human motivation.
