The strategic regulation of children's memory performance and suggestibility

We report two empirical studies that investigated previously reported benefits of a high accuracy motivation, and thus a high threshold, for children's and adults' event recall and for their ability to resist false suggestions. In the studies, 6-, 7-, and 8-year-olds, as well as adults, were shown a brief video about an event and were later asked unbiased and misleading questions about it. In Study 1, participants were either (a) given the typical accuracy instructions (including the option to answer with "I don't know"), (b) reminded of the accuracy instructions during the interview, or (c) immediately given feedback and a token for every correct answer. The results showed that the reminders were ineffective in stimulating strategic control behavior in children, independent of age. In Study 2, the confounding effects of feedback and incentives were disentangled by contrasting (a) free report, (b) feedback only, (c) incentives only, and (d) feedback plus incentives. Analyses on recall performance and suggestibility revealed that both feedback and incentives are necessary to increase children's accurate memory reports.     

A new learning paradigm elicits fast visual discrimination in pigeons

The authors describe a novel multistimulus, multiple-matching learning paradigm for pigeons, which they believe not only simulates pigeons' natural foraging behavior but also more realistically shows their visual discrimination ability. A touch screen thin film transistor panel shows a stimulus configuration consisting of a 2-dimensional array of bitmap images that changes from trial to trial. The pigeon's task during each trial is to peck at images that are defined as positive by the experimenter. An experiment exploring the ability of pigeons to discriminate between achromatic male and female human faces demonstrated the effectiveness of the procedure. In contrast to 12 pigeons that show little improvement over 60 hr of go/no-go discrimination training, 14 multiple-matching pigeons mastered the problem within a few hours.     

The development of organizational strategies in children: evidence from a microgenetic longitudinal study

The authors examined memory on a sort-recall task in children 8 to 12 years of age. Children were first classified as either strategic or nonstrategic on a sort-recall pretest and then participated in an 11-week microgenetic study involving nine sessions. Strategy use was assessed on each trial. Consistent with past longitudinal research, changes from nonstrategic to strategic behavior occurred suddenly rather than gradually. Once children began using organizational strategies, their recall performance improved immediately. Deliberate strategy use was clearly reflected by sorting behavior during encoding but not in clustering during recall. Conclusions about whether there are children with utilization deficiencies are thus affected by how the concept is defined and whether sorting or clustering is taken as the indicator of spontaneous strategy use.     

Target-defining features in a "people-present/people-absent" discrimination task by pigeons

Aust and Huber (2001) demonstrated that in a people-present/people-absent discrimination task, pigeons actually attended to properties of the target (i.e., the human figure). The aim of the present effort was to specify what sort of information contained in the target was used for classification, as well as to investigate whether and in what way the target-defining features interacted. Six pigeons were trained in a go/no-go procedure to discriminate between color photographs characterized by the presence or absence of people. They were then presented with various types of test stimuli that contained some category-relevant features but lacked others. The results showed that properties related to target size and internal structure played an important role and that human silhouettes were insufficient for eliciting a people-present response. Furthermore, some properties of the human figure (e.g., hands/arms) made good predictors of the people-present category, whereas others (e.g., feet/legs or skin color) did not. Responses to test stimuli that belonged to the people-absent category but nevertheless contained some features normally typical for humans (e.g., nonhuman primates) provided evidence that various category-relevant features contributed to classification in an additive way. Taken together, the results suggest that the pigeons made use of a polymorphous class rule involving collections of differently weighted target features.     

Perception and preference in short-term word priming

Responding optimally with unknown sources of evidence (ROUSE) is a theory of short-term priming applied to associative, orthographic-phonemic, and repetition priming. In our studies, perceptual identification is measured with two-alternative forced-choice testing. ROUSE assumes features activated by primes are confused with those activated by the target. A near-optimal decision discounts evidence arising from such shared features. Too little discounting explains the finding that primed words were preferred after passive viewing of primes. Too much discounting explains the findings of reverse preference after active processing of primes. These preference changes highlight the need to use paradigms (like the present ones) capable of separating preferential and perceptual components of priming. Evidence of enhanced perception was found only with associative priming and was very small in magnitude compared with preference effects.     

Significance tests to determine the direction of effects in linear regression models

Previous studies have discussed asymmetric interpretations of the Pearson correlation coefficient and have shown that higher moments can be used to decide on the direction of dependence in the bivariate linear regression setting. The current study extends this approach by illustrating that the third moment of regression residuals may also be used to derive conclusions concerning the direction of effects. Assuming non‐normally distributed variables, it is shown that the distribution of residuals of the correctly specified regression model (e.g., Y is regressed on X) is more symmetric than the distribution of residuals of the competing model (i.e., X is regressed on Y). Based on this result, 4 one‐sample tests are discussed which can be used to decide which variable is more likely to be the response and which one is more likely to be the explanatory variable. A fifth significance test is proposed based on the differences of skewness estimates, which leads to a more direct test of a hypothesis that is compatible with direction of dependence. A Monte Carlo simulation study was performed to examine the behaviour of the procedures under various degrees of associations, sample sizes, and distributional properties of the underlying population. An empirical example is given which illustrates the application of the tests in practice.     

Cross‐cultural evidence of value structures and priorities in childhood

We broaden the developmental focus of the theory of universals in basic human values (Schwartz, 1992, Advances in Experimental Social Psychology) by presenting supportive evidence on children's values from six countries: Germany, Italy, Poland, Bulgaria, the United States, and New Zealand. 3,088 7–11‐year‐old children completed the Picture‐Based Value Survey for Children (PBVS‐C, Döring et al., 2010, J. Pers. Assess., 92, 439). Grade 5 children also completed the Portrait Values Questionnaire (PVQ, Schwartz, 2003, A proposal for measuring value orientations across nations. Chapter 7 in the Questionnaire Development Package of the European Social Survey). Findings reveal that the broad value structures, sex differences in value priorities and pan‐cultural value hierarchies typical of adults have already taken form at this early age. We discuss the conceptual implications of these findings for the new field of children's basic values by embedding them in the recent developmental literature.     

Two Jungs. Apropos a paper by Mark Saban

Jung's idea of the ‘personal equation’ amounts to the reflection that theoretical differences between the psychologies that people teach are rooted in their personalities, in other words, that they are due to the psychology each one ‘has’. This concept also applies to different interpretations of Jung's work. The serious difficulties that Mark Saban has with my psychology are a case in point. Recourse to the concept of the personal equation reveals that Saban has his Jung and I have mine. With his insistence on his Talmudic methodological principle of dream interpretation, that ‘the dream is its own interpretation’, according to Saban Jung means nothing but a rejection of Freudian free association. My Jung goes far beyond that. Jung understands this methodological principle above all in terms of what he calls ‘circumambulation’. The main part of this paper is devoted to an elucidation of what circumambulation involves as a mode of dream interpretation. The paper concludes with the distinction Jung himself introduced between two types of reading of his work, either as ‘paper’ and ‘dead nostrums’ or as ‘fire and wind’, and pleads for a reconstruction of Jung's psychology as a whole in terms of his most advanced, deepest insights, instead of a dogmatic reading mainly based on the early Jung, a reading for which his later revolutionary insights are at best negligible embellishments.
