Exploring the enactment effect from an information processing view: What can we learn from serial position analyses?

The focus of the present article was to analyze processes that determine the enactment and age effect in a multi-trial free recall paradigm by looking at the serial position effects. In an experimental study (see Schatz et al 2010), the performance-enhancing effect of enactive encoding and repeated learning was tested with older and younger participants. As expected, there was a steady improvement of memory performance as a function of repeated learning regardless of age. In addition, enactive encoding led to a better memory performance than verbal encoding in both age groups. Furthermore, younger adults outperformed the elderly regardless of type of encoding. Analyses in the present article show that encoding by enacting seems to profit especially from remembering the last items of a presented list. Regarding age differences, younger outperformed older participants in nearly all item positions. The performance enhancement after task repetition is due to a higher amount of recalled items in the middle positions in a subject performed task (SPT) and a verbal task (VT) as well as the last positions of a learned list in VT.     

Effect of brand name on consumers' risk perceptions of online shopping

The purpose of the present study was to investigate the relationship between brand names and consumers' perceived risk. Hypotheses dealt with whether the presence of a product's brand name affects consumers' perceived risk towards shopping online; whether the familiarity with a brand name influences consumers' perceived risk; and whether online shoppers and non‐shoppers perceive risk towards shopping online differently. Results indicate that the presence or absence of a product's brand name affects online shoppers' perceived risk, but in the opposite direction to that expected. There was no significant difference between online shoppers' perceived risk vis‐à‐vis brand familiarity; however, online shoppers possessed lower perceived risk than non‐shoppers. Implications and limitations are discussed and recommendations for future research are provided. Copyright © 2004 Henry Stewart Publications Ltd.     

Latent Growth Curve and Repeated Measures ANOVA Contrasts: What the Models are Telling You

The relationship between the latent growth curve and repeated measures ANOVA models is often misunderstood. Although a number of investigators have looked into the similarities and differences among these models, a cursory reading of the literature can give the impression that they are very different models. Here we show that each model represents a set of contrasts on the occasion means. We demonstrate that the fixed effects parameters of the estimated basis vector latent growth curve model are merely a transformation of the repeated measures ANOVA fixed effects parameters. We further show that differences in fit in models that estimate the same means structure can be due to the different error covariance structures implied by the model. We show these relationships both algebraically and through using data from a simulation.

An evaluation of computer-based programmed instruction for promoting teachers' greetings of parents by name

Although greeting parents by name facilitates subsequent parent-teacher communication, baseline measures revealed that 4 preschool teachers never or rarely greeted parents by name during morning check-in. To promote frequent and accurate use of parents' names by teachers, the effects of a fully automated computerized assessment and programmed instruction (CAPI) intervention were evaluated in a multiple baseline design. The CAPI intervention involved assessment and training of relations among parents' and children's pictures and names, and produced rapid learning of parent names. The CAPI intervention also resulted in substantial improvements in the classroom use of parents' names for 3 of the 4 teachers; however, a supervisor-mediated feedback package (consisting of instructions, differential reinforcement, and error correction) was necessary to maintain name use for 2 of those teachers. The practical strengths and limitations of computer-based teacher training are discussed.     

The Name-Pronunciation Effect: Further Evidence from Chinese

This study examined the Chinese name-pronunciation effect. The easy-to-pronounce and difficult-to-pronounce Chinese names were created using the same characters in order to control for visual perceptual and conceptual fluency. In Experiment 1, participants rated each name in terms of liking, electability as a state leader, income level, and baby name preference. An additional rating of prevalence was used to estimate familiarity. In Experiment 2, participants did not read the name aloud before rating and performed intentional recall and recognition tests. In both experiments, the easy-to-pronounce names were rated higher than difficult-to-pronounce names on liking. This effect generalized to judgments of electability and baby name preference but not to prevalence and income level. There were no differences in memory performances between the two types of names. Results are discussed in terms of the boundary condition of the name-pronunciation effect and the advantage of using Chinese names to study this effect.     

Name Letter Preferences Are Not Merely Mere Exposure: Implicit Egotism as Self-Regulation

People prefer the letters in their own names to letters that are not in their own names. Furthermore, people prefer the numbers in their own birthdays to numbers not in their own birthdays. In this article we argue that these examples of implicit egotism are best conceptualized as the product of unconscious self-regulation processes rather than a result of mere exposure. In support of this hypothesis, a study of name-letter preferences showed that people preferred their own name letters even when these letters were relatively rare. Furthermore, the name-letter and birthday-number preferences of high and low self-esteem participants diverged in response to an experimentally manipulated self-concept threat. We conclude that implicit egotism, specifically name-letter and birthday-number preferences, represent a form of unconscious self-regulation. Implications of these results for the mere exposure explanation of name-letter preferences and for theory and research in implicit egotism are discussed.     

Drug effects on repeated acquisition: comparison of cumulative and non-cumulative dosing

Pigeons acquired a different four-response chain each session by responding sequentially on three keys in the presence of a sequence of four colors. The response chain was maintained by food presentation under a fixed-ratio schedule. Errors produced a brief timeout but did not reset the chain. Each day there were four 15-minute sessions, with a 10-minute inter-session interval. Cumulative dose-effect curves for phencyclidine, pentobarbital, and d-amphetamine were obtained by giving an injection before each of the four sessions; successive injections increased the cumulative dose in equally spaced logarithmic steps. For comparison, non-cumulative doses of each drug (i.e., doses not preceded by other doses on the same day) were also tested. As the cumulative dose of each drug increased, the overall response rate decreased, the percent errors increased, and there was less within-session error reduction (acquisition). With phencyclidine and pentobarbital, the rate-decreasing and error-increasing effects tended to be greater with a non-cumulative dose than with the corresponding cumulative dose. In contrast, with d-amphetamine, the effects were considerably greater with the cumulative doses. The results indicate that although the cumulative-dosing procedure saved a substantial amount of time in determining dose-effect curves, there were quantitative differences in effects between cumulative and non-cumulative doses.     

Predicting Self‐Confident Behaviour with Implicit and Explicit Self‐Esteem Measures

The present research compared the validity of popular direct and indirect measures of self‐esteem in predicting self‐confident behaviour in different social situations. In line with behavioural dual‐process models, both implicit and explicit self‐esteem were hypothesized to be related to appearing self‐confident to unacquainted others. A total of 127 participants responded to the Rosenberg Self‐Esteem Scale, the Multidimensional Self‐Esteem Scale, and an adjective scale for measuring explicit self‐esteem (ESE). Participants' implicit self‐esteem (ISE) was assessed with four indirect measures: the Implicit Association Test (IAT), the name‐letter task (NLT), and two variants of an affective priming task, the reaction‐time affective priming task (RT‐APT) and the error‐based affective priming task (EB‐APT). Self‐confident behaviour was observed in four different social situations: (i) self‐introduction to a group; (ii) an ostracism experience; (iii) an interview about the ostracism experience; and (iv) an interview about one's personal life. In general, appearing self‐confident to unknown others was independently predicted by ESE and ISE. The indirect measures of self‐esteem were, as expected, not correlated, and only the self‐esteem APTs—but not the self‐esteem IAT or the NLT—predicted self‐confident behaviours. It is important to note that in particular the predictive power of the self‐esteem EB‐APT pertained to all four criteria and was incremental to the ESE measures.
