The role of the natural history museum in promoting word learning for young children

Although strong claims have been made about museums being ideal word learning environments, these are yet to be empirically supported. In the current study, 152 four- to five-year-olds children (81-M, 71-F) from minority backgrounds were taught six vocabulary items either in a museum, in their classroom with museum resources, or in their classroom with classroom resources. At test, children taught in their classroom with museum resources produced significantly more correct responses than children taught in the museum or in their classroom with classroom resources. Children were also significantly better at retaining the target vocabulary items than recalling them. These data demonstrate how context can impact word learning and point to the benefits of a collaborative relationship between schools and museums to support children's language development.     

Children's explanations for self‐presentational behaviour

Previous research has underestimated children's capacity to understand the self‐presentational behaviour of other people. We argue from recent research in mental‐state understanding that 8‐year‐olds should be able to attribute self‐presentational motives in order to explain others' behaviour. In the present study, children aged 6 to 11 years heard stories involving emotion‐masking displays and were then asked to explain the motivations for those displays. Results supported our prediction.

Attention focusing instructions and coordination bias: Implications for learning a novel bimanual task

Four groups learnt a novel bimanual coordination movement pattern under instructions designed to manipulate focus of attention. It was predicted that instructions directing attention onto the effects of the action would facilitate learning. Three groups received demonstrations of the required 90° relative phase movement. Two of the demonstration groups also received instruction directing attention either towards the feedback (EXTERNAL), or the relationship between their arm movements and the feedback (RELATION). The third group received no attention directing instructions (DEMO). A final group was only provided with goal relevant feedback (NO DEMO). A scanning task enabled coordination bias to be assessed pre-practice. This was conducted to ensure task novelty and assign participants equally across groups based on strength of bias to in- and/or anti-phase. Acquisition rate was slower for the DEMO only group, especially compared to the EXTERNAL group. Additionally, participants biased to in-phase (as compared to anti-phase) during the scanning trial also showed high error early in practice. These differences remained in retention. Irrespective of feedback condition the DEMO group evidenced the most error in retention. However, all groups were affected by the removal of on-line feedback, although the attention-directing instructions provided during practice somewhat decreased the negative effects associated with feedback removal. Overall, the in-phase-biased participants were most affected by withdrawal of feedback. It was concluded that movement demonstrations alone do not facilitate learning of a novel coordination task, unless additional goal-directed instruction is provided. Additionally, individual differences in coordination bias pre-practice can be used to predict learning rate and quality.     

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.
