Performance evaluations, need for cognition, and the acquisition of a complex skill: an attribute–treatment interaction

We proposed that intermittent evaluations of performance could be used to promote the acquisition of a complex skill. We also hypothesized that trainees low in need for cognition (NFC) would benefit more from intermittent evaluations compared to trainees high in NFC. Accordingly, 106 young adult males participated in 5 h of training in order to learn a complex computer task that simulated the demands of a dynamic aviation environment. Trainees’ performance was assessed either intermittently during training or at the end of training. Results indicated that intermittent performance evaluations enhanced the skill-based learning of trainees low in NFC, whereas intermittent skill evaluations tended to undermine the skill-based learning of trainees high in NFC. The findings are discussed in relation to Deci’s (1975) theory of intrinsic motivation and the need for more research examining attribute–treatment interactions with respect to training and skill acquisition.     

Spatial and non-spatial visual discrimination learning in zebrafish (Danio rerio)

Zebrafish (Danio rerio) provide an excellent model for assessment of molecular processes of neurodevelopment. To determine the functional importance of molecular events during neurodevelopment, we have developed methods for assessing learning in zebrafish in a three-chambered fish tank. In the first study, simple escape response was assessed. Zebrafish tested with a moving net learned to escape to another chamber more rapidly over the six sessions of training than the fish with the still net which did not learn. Upon reversal of the contingencies, the fish switched to the inactive net rapidly learned to suppress the escape response and fish formerly in the inactive net condition learned to avoid the moving net. In the second study, spatial discrimination learning was assessed. Zebrafish were trained on a right-left position discrimination to avoid the active net. Zebrafish showed significant improvement in escape responses over six sessions of training with three trials per session. In the third study, red-blue non-spatial discrimination learning was assessed. There was a significant improvement over the first six training sessions. With the reversal of contingencies, there was a significant decline of performance. With continued training, the fish again significantly improved avoidance. These studies found an effective motivational stimulus and procedure for studying escape behavior in zebrafish; a procedure whereby zebrafish would learn both spatial and non-spatial discrimination. These methods are being developed to help determine the functional importance of molecular events during zebrafish neurodevelopment.

Philosophy and language learning

In this paper, I explore different ways of picturing language learning in philosophy, all of them inspired by Wittgenstein and all of them concerned about scepticism of meaning. I start by outlining the two pictures of children and language learning that emerge from Kripke’s famous reading of Wittgenstein. Next, I explore how social-pragmatic readings, represented by Meredith Williams, attempt to answer the sceptical anxieties. Finally, drawing somewhat on Stanley Cavell, I try to resolve these issues by investigating what characteristically happens to our view of language learning when we do philosophy. The focus throughout is on the relation between the individual (the learning child) and the community (usually represented by the parents), and how that relation is deformed when we operate with a certain philosophical notion of ground.     

Achievement Goals in Social Interactions: Learning with Mastery vs. Performance Goals

Little work has studied achievement goals in social interaction situations. The present experiment aimed at contributing to this matter by showing the potential of social interaction (in particular disagreement) to moderate the effects of achievement goals on learning. Participants were led to think they interacted with a partner, sharing opinions about a text that they were studying. Mastery and performance goals were manipulated. During the “interaction,” they received either disagreement or agreement from this bogus partner. Results showed that a condition in which mastery goals were induced led to better learning than a performance goal condition only when the partner disagreed. No differences between goal conditions were observed when the partner agreed. Implications for achievement goal research are discussed. Part of this work was conducted during Céline Darnon’s doctoral dissertation under the supervision of Fabrizio Butera, and was written during Céline Darnon’s post-doctorate at the University of Wisconsin-Madison, USA, thanks to a Fulbright fellowship.     

Error self-correction and spelling: improving the spelling accuracy of secondary students with disabilities in written expression

In order to improve the spelling performance of high school students with deficits in written expression, an error self-correction procedure was implemented. The participants were two tenth-grade students and one twelfth-grade student in a program for individuals with learning disabilities. Using an alternating treatments design, the effect of error self-correction was compared with a more traditional method of spelling practice. The intervention and follow-up phases were implemented over a 6-week period with maintenance checks conducted 4 and 8 weeks after the termination of instruction. Results indicated that the error self-correction procedure was superior to the traditional method of review during the intervention and follow-up phases, but some gains were lost during the maintenance phase.     

Change one can believe in: Adding learning to computational models of self-regulation

Theories of self-regulation describe motivation as a dynamic process of goal choice and goal striving. To facilitate those processes, individuals learn about themselves and their environment, which is an internal dynamic process. However, the precise nature of the relationship between these learning and motivational processes is not well specified. This article integrates formal models of learning, goal choice, and goal striving using a single information processing structure found in self-regulatory models of motivation. Results from two published studies ( and ) validate the model. In both cases, the integrated model accounts for findings that previous theories of self-regulation could not explain. Discussion focuses on additional tests to validate the model and on the value of incorporating formal models from the cognitive, learning, and motivational literatures to account for behavior in complex settings and over time.
