Transfer and the organization of Perceptual-Motor space

Summary Three experiments are reported involving transfer of effects of different types of visual distortion: lateral displacement, linear extent, and visual rotation. Transfer between different body parts and between different dimensions of space occur but to varying degrees. These are interpreted in terms of their implications for understanding the organization of perceptual and perceptual-motor space.This research was supported by the Center for Research in Human Learning of the University of Minnesota, and by grants 1-K3-HD 12,396, HD 03082 to the University of Minnesota.

Self‐Regulation and Power: How Self‐Regulatory Failures Can Enhance Social Power

Low self‐control is often associated with poor life outcomes. Here, we propose that self‐control failures may also provide social benefits by signaling and maintaining power. We identify several pathways by which reduced self‐control can assist in ascending social hierarchies. First, the self‐enhancing tendencies adopted by people with low self‐control may contribute to making positive first impressions and advertising power to new acquaintances. The direct and disinhibited communication styles that stem from self‐control failures may also enhance power and lubricate difficult social interactions. Disinhibited aggression can help people maintain and acquire material resources and establish dominance over rivals. Finally, the parallels between the behavior of people with low self‐control and people with power (e.g., self‐enhancement, disinhibition, approach‐orientation, aggression) suggest that people with impaired self‐control will be perceived as more powerful than people with intact self‐control. Evidence for these propositions and directions for future research are discussed.     

Two reference frames for visual perception in two gravity conditions

The processing and storage of visual information concerning the orientation of objects in space is carried out in anisotropic reference frames in which all orientations are not treated equally. The perceptual anisotropies, and the implicit reference frames that they define, are evidenced by the observation of 'oblique effects' in which performance on a given perceptual task is better for horizontally and vertically oriented stimuli. The question remains how the preferred horizontal and vertical reference frames are defined. In these experiments cosmonaut subjects reproduced the remembered orientation of a visual stimulus in 1g (on the ground) and in 0g, both attached to a chair and while free-floating within the International Space Station. Results show that while the remembered orientation of a visual stimulus may be stored in a multimodal reference frame that includes gravity, an egocentric reference is sufficient to elicit the oblique effect when all gravitational and haptic cues are absent.     

Cognitive style and customer orientation

Cognitive style, the ways in which we take in information from the environment and process that information, has been shown to influence interactions in various behavioral fields. This paper investigates whether cognitive style would impact an individual's orientation toward the customer or toward the sale, as measured by the SOCO scale. The results suggest that cognitive style can influence one's orientation. This knowledge should prove useful to sales managers in designing training programs for new sales personnel, as well as in assigning sales personnel to specific selling tasks.     

Servo Hypotheses for the Biological Control of Movement

An analysis is made of equilibrium-point models for motor control, describing these models in the context of servo control mechanisms. We considered issues of speed and stiffness scaling that are incompatible with current formulations of the equilibrium-point models. A modification of the equilibrium-point models is proposed in which the central nervous system controls velocity as well as positions during the course of fast 1imb movements. Numerical simulations are presented that verify that such a servo control mechanism could successfully produce fast limb movements, as observed in human subjects     

A meta-analysis of the regulatory focus nomological network: Work-related antecedents and consequences

Regulatory focus theory (Higgins, 1997, 1998) has received a great deal of recent attention in the organizational behavior literature. Despite the amount of new evidence surrounding regulatory focus and its relationships with other variables, a quantitative summary of this literature is lacking. The authors used meta-analysis to summarize correlations from 77 empirical studies that included self-report measures of promotion and prevention focus. Meta-analytic effect sizes between promotion and prevention focus and work-related variables are reported. In general, results indicated that promotion and prevention focus are orthogonal constructs and each construct is uniquely related to other theoretically relevant constructs. The results also demonstrate the importance of regulatory foci to organizational researchers as well as the need for a unified approach to their measurement.     

Long-term transfer of learning from books and video during toddlerhood

Television viewing and picture book reading are prevalent activities during toddlerhood, and research has shown that toddlers can imitate from both books and videos after short delays. This is the first study to directly compare toddlers' long-term retention rates for target actions learned from a video or book. Toddlers (N=158) at 18- and 24-months of age saw an experimenter demonstrating how to make a novel three-step toy rattle via a prerecorded video or a picture book. The toddlers' imitation of the target actions was tested after a specific delay (e.g., 2, 4 weeks), and their performance was compared with that of age-matched controls who did not see a demonstration. The 18-month-olds retained the target actions for 2 weeks, exhibiting forgetting at 4 weeks, whereas the 24-month-olds retained the information for up to 4 weeks, exhibiting forgetting at 8 weeks. Retention rates for books and videos did not differ at either age. These findings demonstrate very impressive retention from a brief two-dimensional media demonstration, and they contribute to our overall understanding of long-term memory processes during infancy.
