On the Emergence of Human Goal Pursuit: The Nonconscious Regulation and Motivation of Goals

Experimental research in social psychology has discovered that human goal pursuit can emerge in the absence of conscious awareness. Whereas these goal-priming effects are commonly explained in terms of habitual automatic processes, recent studies shed new light on the matter. Building on this recent work, this paper attempts to promote a more comprehensive understanding and examination of the potential mechanisms that enable people to pursue their goals in a nonconscious fashion. Specifically, it addresses (i) the human capacity to pursue goals without awareness of the activation and operation of the goal, even when habits are inadequate; and (ii) the fundamental role of positive affect in nonconsciously modulating the motivation of goals and their pursuit.     

A generalization of Takane's algorithm for dedicom

An algorithm is described for fitting the DEDICOM model for the analysis of asymmetric data matrices. This algorithm generalizes an algorithm suggested by Takane in that it uses a damping parameter in the iterative process. Takane's algorithm does not always converge monotonically. Based on the generalized algorithm, a modification of Takane's algorithm is suggested such that this modified algorithm converges monotonically. It is suggested to choose as starting configurations for the algorithm those configurations that yield closed-form solutions in some special cases. Finally, a sufficient condition is described for monotonic convergence of Takane's original algorithm.Financial Support by the Netherlands organization for scientific research (NWO) is gratefully acknowledged.

Evaluating a ward staff program for increasing spontaneous and varied communicative gesturing with individuals who are mentally retarded

In the present study we assessed the effect of a multifaceted program for ward staff members, which was intended to have severely/profoundly mentally retarded individuals improve their use of communicative gestures. The program consisted of instruction, verbal and visual (publicly posted) graphic feedback. There were two categories of dependent variables. The first category involved the number of gesture prompts by staff, number of unused opportunities to evoke gestures, and number of consequences given for gestures. The second category involved handicapped individuals' number of prompted gestures, number of spontaneous gestures, and number of different gestures. Results show that the program was effective with regard to all these variables. Changes in the number of spontaneous gestures were especially remarkable, as this variable had not been influenced directly. Follow-up data underline the effectiveness of the program.
