Long-term autobiographical memory across middle childhood: patterns,predictors, and implications for conceptualizations of childhood amnesia

ABSTRACT

We examined recall of events by children 4–11 years to inform patterns of retention of autobiographical memories as well as factors that predict their survival. 101 children participated in a 4-year prospective study. At study inception, children were 4, 6, and 8 years. They were tested annually for three more years for a total of four waves of data collection. At each wave, we obtained narrative reports of recent (all waves) and distant (Waves 2–4) events, resulting in virtually continuous sampling of memories formed by 4- to 11-year-olds and recalled after 1–3-year delays. We also measured children's language, and domain-general and memory-specific cognitive skills. Multi-level modelling revealed age-related increases in the likelihood of survival of memories over the delays. Critically, the rate of increase in retention of individual memories was the same across the cohorts. In addition to age, thematic coherence of original memory reports predicted memory survivability. Other factors were not predictive. The dense sampling and prospective tracking of memories across the 4–11-year age period permitted an especially strong test for continuity versus discontinuity in autobiographical memory across the second half of the first decade of life. The data are strongly indicative of continuity and gradual change.     

Neural binding of space and time: An introduction

Some of the central problems to be solved by the brain, such as figure-ground coding and object recognition, concern the binding of separately coded feature elements into coherent object representations. The binding problem has recently been approached by a variety of disciplines, notably psychophysics and experimental psychology, electrophysiology and neurophysiology, and computational modelling. This Special Issue brings together 21 of papers, mainly all from psychology and computational modelling, that address issues in Gestalt formation, the relation of the grouping and binding processes to visual attention, the role of temporal factors for grouping and binding, the neuronal correlates of binding mechanisms, the development of binding operations in infants, and the breakdown of these processes following brain damage.     

Visual search for dimensionally redundant pop-out targets: Redundancy gains in compound tasks

Two visual search experiments investigated the detection of odd-one-out feature targets redundantly defined on multiple dimensions. Targets differed from the distractors in either orientation or colour or both (redundant targets). In Experiment 1, the three types of target were presented either in separate trial blocks or randomized within blocks, and the task involved either a simple target detection response or a “compound” response based on the position of dials inside the target. Mean reaction times (RTs) were faster to redundant targets than to singly defined targets, with greater gains in simple detection than in compound tasks. Further, simple detection RTs to redundant targets were faster than the fastest RTs to singly defined targets, violating Miller's (1982) “race model inequality” (RMI). Experiment 2 showed that, with compound tasks, mean RT redundancy gains (and violations of the RMI) depend on practice. The results suggest that separate colour and orientation feature contrast signals coactivate perceptual mechanisms involved in target detection.     

Two spatial maps for perceived visual space: Evidence from relative mislocalizations

When observers are asked to localize the peripheral position of a target with respect to the midposition of a spatially extended comparison stimulus, they tend to mislocalize the target as being more outer than the midposition of the comparison stimulus (cf. Müsseler, Van der Heijden, Mahmud, Deubel, & Ertsey, 1999). For explaining this finding, we examined a model that postulates that in the calculation of perceived positions two sources are involved, a sensory map and a motor map. The sensory map provides vision and the motor map contains information for saccadic eye movements. The model predicts that errors in location judgements will be observed when the motor map has to provide the information for the judgements. In four experiments we examined, and found evidence for, this prediction. Localization errors were found in all conditions in which the motor map had to be used but not in conditions in which the sensory map could be used.     

Redesigning work through idiosyncratic deals

This study links idiosyncratic deals (i-deals) to job design theory. It investigates the impact of individually negotiated job changes on performance, self-efficacy, and psychological strain through their intervening effects on work design. Based on a sample of 187 health care professionals employed by a hospital in Germany, three types of work design-related i-deals were investigated: (1) task, (2) career, and (3) flexibility i-deals. Consistent with hypotheses, the three types of i-deal had differential effects on work characteristics, and each in turn related to different outcomes. Specifically, job autonomy mediated the task i-deals—job performance relationship; skill acquisition mediated the career i-deals—occupational self-efficacy relationship; and reduced work overload mediated the flexibility i-deals—emotional and affective irritation relationships. Leader–Member Exchange was confirmed as an antecedent of all three types of i-deals. Task, career, and flexibility i-deals are discussed as ways to make work more intrinsically motivating, ensure one’s professional advancement, and balance workplace stressors.     

The Foundations of Capability Theory: Comparing Nussbaum and Gewirth

This paper is written from a perspective that is sympathetic to the basic idea of the capability approach. Our aim is to compare Martha Nussbaum’s capability theory of justice with Alan Gewirth’s moral theory, on two points: the selection and the justification of a list of central capabilities. On both counts, we contend that Nussbaum’s theory suffers from flaws that Gewirth’s theory may help to remedy. First, we argue that her notion of a (dignified) human life cannot fulfill the role of a normative criterion that Nussbaum wants it to play in selecting capabilities for her list. Second, we question whether Nussbaum’s method of justification is adequate, discussing both her earlier self-validating argumentative strategy and her more recent adherence to the device of an overlapping consensus. We conclude that both strategies fail to provide the capabilities theory with the firm foundation it requires. Next, we turn to Gewirth’s normative theory and discuss how it can repair these flaws. We show how his theory starts from a fundamental moral principle according to which all agents have rights to the protection of the necessary preconditions of their agency. Gewirth’s justification of this principle is then presented, using a version of a transcendental argument. Finally, we explicitly compare Nussbaum and Gewirth and briefly demonstrate what it would mean for Nussbaum to incorporate Gewirthian elements into her capabilities theory of justice.     

The Creative Brain: Corepresenting Schema Violations Enhances TPJ Activity and Boosts Cognitive Flexibility

Cognitive flexibility is one of the essential mental abilities underlying creative thinking. Previous findings have shown that cognitive flexibility can be enhanced by schema violations, and it has been suggested that active involvement is needed for schema violations to facilitate cognitive flexibility. The possibility that identification with an actor performing a schema violation (i.e., corepresenting an active schema violation) can enhance cognitive flexibility was investigated in 2 studies. In the first study, under conditions of high or low identification, participants watched an actor preparing a sandwich. The way the actor made the sandwich followed either a schema violation or contained the normal schema of preparing a sandwich. When identification was high, watching a schema-violation-enhanced cognitive flexibility as compared to watching the corresponding normal event. No effect of schema violation occurred under conditions of low identification. As little is known about the neural correlates of schema violations, in the second study the brain activity during schema violations was explored by means of functional Magnetic Resonance Imaging (fMRI). Participants were instructed to identify with an actor and brain activity was measured while participants watched the actor performing a schema violation or the corresponding normal schema. Activity in the temporal parietal junction (TPJ), a brain region that is associated with violation of expectations, was higher in the schema-violation condition than in the normal schema condition. These findings enhance the theoretical understanding of the effects of schema violations and may provide important practical implications in various settings where creative thinking is needed.     

The Creative Process in Visual Art: A Longitudinal Multivariate Study

The purpose of this research was to study the creative process in real-life settings and in a multicomponential perspective of creativity. Relations between the creative process and other important variables (mood, personality, and the creative product) were investigated. The data analyzed were collected in four applied art schools (n = 41) in Switzerland, during mandatory workshops. The creative process was operationalized through 2 subprocesses: generation (idea production) and selection (idea evaluation), both repeatedly measured across the workshops. The trajectories of theses subprocesses were modeled with a commonly used statistical model for longitudinal data (Latent Growth Models). Results showed that generation had an overall decreasing pattern through time, whereas selection had an inverted U-shaped pattern. Important individual differences in both subprocesses and related variables were also found, many of which had strong predictive validity. Indeed, process and personality variables explained 70% of the variance of the evaluation of the final product.
