Overpayment: Perceived qualifications and financial compensation

In this study expectancy and equity theory were compared. An experiment was carried out on the effect of overpayment. Overpayment was manipulated by varying perceived input (perceived qualifications) and received outcome (financial compensation). The experiment consisted of a 2 × 3 design: two levels of payment (4 guilders p.h. and 8 guilders p.h.) and three levels of perceived qualifications (high, medium, low). Sixty-six subjects were hired through the students placement service to decode personality questionnaires. Overpayment by manipulation of monetary rewards did not lead to greater production, as was hypothesized by Adams' equity theory (1965). As far m overpayment has been manipulated by perceived qualifications for the job the data confirmed equity theory. Several other theories (e.g. expectancy theory: Lawler, 1968b) can explain both results.     

Retrieval-induced forgetting in implicit memory tests: The role of test awareness

Retrieval practice with particular items in memory may result in decreased recall of different, semantically related, items. This retrieval-induced forgetting effect has been demonstrated in studies using explicit memory tests. Anderson and Spellman (1995) have attributed retrieval-induced forgetting to inhibitory mechanisms. This hypothesis predicts similar effects in implicit memory tasks. In our first experiment, using Anderson and Spellman’s original paradigm, retrieval-induced forgetting was found using an explicit memory test with independent extralist retrieval cues. In our second experiment, using the same materials, retrieval-induced forgetting was also found using an implicit memory test with independent extralist retrieval cues, but only for participants who were aware of the relationship between the study and practice phase on the one hand, and the test phase of the experiment on the other. Thus, test awareness seems to mediate retrieval-induced forgetting in implicit memory tasks.     

A functional analysis of personal autonomy: How restricting ‘what’, ‘when’ and ‘how’ affects experienced agency and goal motivation

Personal autonomy is central to people's experiences of agency and abilities to actively take part in society. To address the challenges of supporting autonomy, we propose a functional model of autonomy, according to which the experience of agency is a function of the opportunity to determine what to do, when to act and how to act in goal-pursuit. We tested the model in three experiments where the three goal-pursuit components could be constrained by another person or an artificial intelligence (AI) agent. Results showed that removing any of the three components from one's own decisions reduced experienced agency (Study 1a and 1b) and lowered motivation to pursue goals in organisational contexts (Study 2). In comparison to the strong and robust main effects, interactions between the components and the effects of the source of restriction (human vs. AI) were negligible. Implications for personal autonomy, algorithmic decision-making and behaviour change interventions are discussed.     

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.
