Help-seeking: An understudied problem-solving skill in children

Traditional approaches to the study of young children's behavior in helping relationships are examined and criticized as inadequate because they have failed to represent the child's perspective from the role of “active helpee” (i.e., help-seeker in such relationships). By failing to look at helping from the perspective of the one who seeks help, researchers have neglected to pursue an important lead in understanding why some children are able to learn and progress independently when confronted with the same obstacles that serve to defeat other children. This article focuses on instrumental help-seeking defined as an active, complex social-cognitive activity that is essential to learning and achievement. In the first sections of this article, it is argued that instrumental help-seeking can be formally distinguished from passive dependency as well as from the actual giving and receiving of help. In following sections, a heuristic model of the help-seeking process is offered, prior research relevant to the model is reviewed, and ideas for research on help-seeking in children are suggested within the framework of this model.     

Dementia in Parkinson disease: A neuropsychological analysis

An extensive set of neuropsychological measures was administered to 60 Parkinson's disease patients and age-, sex-, and education-matched controls in order to investigate the nature and prevalence of the cognitive deficit in the disease. Parkinsonian patients performed significantly poorer on all measures with the exception of tests for apraxia and object recognition, and on a test of vocabulary knowledge. Discriminant analysis of the test data revealed that over 93% of patients are impaired relative to matched controls, but that assigning a prevalence rate for dementia in the disease may be difficult due to the continuous distribution of cognitive deficits.     

Synesthesia: II. Psychophysical relations in the synesthesia of geometrically shaped taste and colored hearing

The psychophysical function in two synesthetic subjects, one with geometrically shaped taste and the other with colored hearing, is investigated. Each synesthete is compared with three control subjects. Pilot studies are used to construct appropriate response domains. Compared to controls, synesthetes give a restricted set of responses that are also asymmetric with respect to the range of choices available in various subsets of the response domain. A combination of absolute and relative effects is also distinctive of synesthetic percepts. It is concluded that synesthesia is a distinct phenomenon unlike ordinary mediated associations, and occupies an intermediate position in the range of simple to complex brain mechanisms.     

The home observation for measurement of the environment (HOME) scale: A review of research

Caldwell's Home Observation for Measurement of the Environment (HOME) scale is perhaps the most widely used instrument to assess the quality of a young child's home learning environment. In this paper, the HOME'S psychometric properties and methodological uses are explored, and its utility as a research and clinical instrument is examined. Strengths of the HOME scale include the relatively wide range of information available pertaining to its psychometric properties and its use in studies of a variety of populations for a variety of purposes. Weaknesses include the fact that most research relating HOME scores to later child development is correlational. Several suggestions for future research are offered.     

Remembering,understanding, and representation

Starting with the facts that not everything that is understood is remembered, and that not everything that is remembered is understood. this paper urges that models of language processing should be able to make a distinction between comprehension and memory. To this end. a case is made for a spreading activation process as being the essential ingredient of the comprehension process. It is argued that concepts activated during comprehension not only restrict the search set for candidate concepts to be used in a top-down fashion, they also constitute part of an episodic representation that can come to be p e of long-term memory. The way in which these representations atrophy is discussed, as is the way in which their idiosyncratic components are eliminated in producing representations in semantic memory. Some observations on the comprehension and memory of text are made and arguments are presented to show how intrusions and omissions in recall can be handled. Some existing experimental data is reanalyzed in terms of the proposed model and alternative interpretations consistent with the model are shown to be possible.     

The cognitive structure of social categories

Support for the prototype theory of categorization was found in a study of the structure of social categories. Though occupational terms such as DOCTOR are socially defined, they do not have the classical structure their clear definitional origins would predict. Conceptions of social categories are richer and more complex than those of physical object categories and subjects agree upon them. Comparison of various instructions for eliciting attributes of categories showed that whether subjects are asked to define a term, give characteristics, or describe ways they recognize members of categories, the attributes they list contribute to a prototype structure. These data provide evidence against the view that prototype structure is relevant only to an identification procedure and not to the core of concepts, as has been suggested.
