Reminiscing and recounting in the preschool years

Talk about past events can be classified as either reminiscing (discussing shared experiences) or recounting (discussing unshared experiences). Reminiscing may have more of a social memory function whereas recounting may also be informational. This research focused on the form of mother–child reminiscing and recounting during the preschool years. Twenty 40‐month‐old and 20 58‐month‐old children reminisced and recounted past events with their mothers. Results showed that mothers who provided more memory information during reminiscing and requested more memory information during recounting had children who reported more unique information about the events. Regardless of maternal conversational style, however, children reported more unique memory information during recounting than reminiscing. We discuss these results in terms of the importance of both forms of remembering for autobiographical memory development. Copyright © 2000 John Wiley & Sons, Ltd.     

Reflections on how color term acquisition is constrained

Compared with object word learning, young children typically find learning color terms to be a difficult linguistic task. In this reflections article, I consider two questions that are fundamental to investigations into the developmental acquisition of color terms. First, I consider what constrains color term acquisition and how stable these constraints are over culture and age. I review recent studies that have identified conceptual, attentional, and linguistic constraints that seemingly operate on the acquisition of color terms compared with object words and the differential acquisition of color terms within a given language. Second, I consider whether these constraints are specific to the acquisition of color terms or whether they reflect more general constraints that operate on other classes of lexical terms such as different abstract property terms.     

Intuition,affect, and personality: unconscious coherence judgments and self-regulation of negative affect

According to personality systems interaction theory, a negative mood was expected to reduce access to extended semantic networks and to reduce performance on intuitive judgments of coherence for participants who have an impaired ability to down-regulate negative affect (i.e., state-oriented participants). Consistent with expectations, state-oriented participants reporting higher levels of perseverating negative mood had a reduced discrimination between coherent and incoherent standard word triples (Study 1) and individually derived word triples describing persons (Study 2). Participants who are able to down-regulate negative affect (i.e., action-oriented participants) did not show this tendency. In addition, Study 2 revealed a dissociation between state orientation and Neuroticism that is discussed in terms of a functional difference between the two constructs.     

Dissociating perception and action in Kanizsa's compression illusion

When a horizontally elongated surface is occluded in the middle by a larger surface, it appears narrower than its true width (Kanizsa’s compression illusion). We report that a similar compression effect occurs for closed-loop visuomotor matches of size, but not for otherwise comparable open-loop “mimed” reaching or size-matching visuomotor responses. Our study is the first in which a comparison of size perception in personal space with bilateral actions performed with both hands (instead of precision grips employing the thumb and the index finger) is used to investigate motor responses to Kanizsa’s compression illusion. Implications for the current debate on the existence of dissociations between spatial perception and visually controlled actions in personal space are discussed.     

Unifying sequential effects in perceptual grouping

Temporally-extended perception involves a delicate balance of constancy and change. 'This can be seen, for instance, when viewing bistable figures such as the Necker cube. A recent study by Gepshtein and Kubovy of sequential effects in multistable dot lattices demonstrates constancy and change within the same set of data. They propose that these opposing trends might be explained by the same single factor: a persistent random orientation bias that is intrinsic to brain activity. This proposal could form the basis for a new account of multistability.     

Affect sensitivity and affect regulation in dealing with positive and negative affect

Interactions between two types of affect sensitivity and two types of affect regulation were tested: low sensitivity to positive affect and high sensitivity to negative affect were expected to become maladaptive when self-motivation and self-relaxation are low, respectively. Consistent with expectations, specific Sensitivity × Regulation interactions emerged: low sensitivity to positive affect (i.e., independent, schizoid-like personality) was only associated with reduced emotional well-being when self-motivation was low. High sensitivity to negative affect (i.e., self-critical, avoidant-like personality) was only associated with psychosomatic symptoms when self-relaxation was low. In a subsample, the same results were obtained longitudinally. Findings support the distinction between affect sensitivity and affect regulation. Furthermore, affect regulation can be differentiated into self-motivation and self-relaxation.     

Disjunctive logic programming with types and objects: The DLV system

The paper presents DLV⁺, a Disjunctive Logic Programming (DLP) system with object-oriented constructs, including classes, objects, (multiple) inheritance, and types. DLV⁺ is built on top of DLV (a state-of-the art DLP system), and provides a graphical user interface that allows one to specify, update, browse, query, and reason on knowledge bases. Two strong points of the system are the powerful type-checking mechanism and the advanced interface for visual querying.DLV⁺ is already used for the development of knowledge based applications for information extraction and text classification.     

Reality monitoring and resistance to forgetting under short delay intervals

In three experiments, participants were asked to perform simple action statements or to imagine performing the actions in a single study session. In a test session that occurred 1 hr, 24 hr, 48 hr (Experiments 1a and 1b), or 1 week later (Experiments 2 and 3), participants were instructed to tell whether the action statement had been carried out or imagined. The primary finding was that, overall, recognition and reality monitoring showed a comparable rate of forgetting. The results add evidence to the hypothesis that, also after long retention delays, discrimination between an internal and an external source may not be inferior to item recognition. A new theoretical proposal to account for these findings is outlined.     

Examining action effects in the execution of a skilled soccer kick by using erroneous feedback

The authors examined the role of action effects (i.e., ball trajectory) during the performance of a soccer kick. Participants were 20 expert players who kicked a ball over a height barrier toward a ground-level target. The authors occluded participants' vision of the ball trajectory after foot-to-ball contact. Participants in a 1st group received erroneous feedback from a video that showed a ball-trajectory apex approximately 75 cm lower than that of their actual kick, although the ball's landing position was unaltered. Participants in a 2nd group received correct video feedback of both the ball trajectory and the landing position. The erroneous-feedback group showed a significant bias toward higher ball trajectories than did the correct-feedback group. The authors conclude that performers at high levels of skill use the visual consequences of the action to plan and execute an action.
