Enhanced recency effects with changing-state and primary-linguistic stimuli

A number of explanations for the modality effect in immediate serial recall have been proposed. The auditory advantage for recall of recency items has been explained in terms of (1) the contributions of precategorical acoustic storage (PAS), (2) an advantage of changing-state over static stimuli, and (3) an advantage of primary-linguistic coding. Four experiments were conducted to evaluate these hypotheses. In the first, subjects viewed seven consecutive rectangles of different colors on a computer monitor. A small recency effect was obtained when the task was to recall the colors of the rectangles in order, with the size of the effect being independent of whether the rectangles remained stationary on the screen or moved in one of four directions. However, when the task was to recall the direction of movement of the rectangles, a larger recency effect was found. This pattern of results was interpreted as suggesting that recency effects are enhanced by changing-state stimulus information, but only when the changing-state information serves to identify the stimulus. Experiments 2 and 3 provided converging evidence by demonstrating an analogous recency advantage for changing-state visual stimuli that were somewhat different from those of Experiment 1. Experiment 4 demonstrated recency effects with synthesized speech stimuli that were substantially greater than were those found with the changing-state visual stimuli of the first three experiments. Implications of the results for the PAS, changing-state, and primary-linguistic hypotheses, as well as temporal-distinctiveness theories of recency, are discussed.     

Pragmatic reasoning schemas

We propose that people typically reason about realistic situations using neither content-free syntactic inference rules nor representations of specific experiences. Rather, people reason using knowledge structures that we term pragmatic reasoning schemas, which are generalized sets of rules defined in relation to classes of goals. Three experiments examined the impact of a “permission schema” on deductive reasoning. Experiment 1 demonstrated that by evoking the permission schema it is possible to facilitate performance in Wason's selection paradigm for subjects who have had no experience with the specific content of the problems. Experiment 2 showed that a selection problem worded in terms of an abstract permission elicited better performance than one worded in terms of a concrete but arbitrary situation, providing evidence for an abstract permission schema that is free of domain-specific content. Experiment 3 provided evidence that evocation of a permission schema affects not only tasks requiring procedural knowledge, but also a linguistic rephrasing task requiring declarative knowledge. In particular, statements in the form if p then q were rephrased into the form p only if q with greater frequency for permission than for arbitrary statements, and rephrasings of permission statements produced a pattern of introduction of modals (must, can) totally unlike that observed for arbitrary conditional statements. Other pragmatic schemas, such as “causal” and “evidence” schemas can account for both linguistic and reasoning phenomena that alternative hypotheses fail to explain.     

Perceptions of school psychology services from a staff perspective

This investigation examined how staff in an elementary school district perceived their school psychologists and how these perceptions differed across components of service and staff groups. We developed a School Psychological Service Questionnaire and then analyzed responses from regular education teachers, special education teachers, principals, and school psychologists in an urban school district. Although the findings are numerous, most noteworthy are, first, that consumer groups in the district had different perceptions than school psychologists about how school psychologists allocate their time and how this time should be allocated in the future. Second, consumer perceptions of school psychologists' knowledge generally were favorable. Third, in terms of domains appropriate for involvement by school psychologists, a factor analysis of consumer ratings revealed three relatively clear dimensions of recommended service provision — special education activities, interpersonal or school-climate activities, and administrative responsibilities. Fourth, the helpfulness of school psychologists, as perceived by consumers, related positively to frequency of contact. Fifth, differences in perception of school psychological services were evident across staff groups. Finally, comparisons between master's level and doctoral level school psychologists suggested numerous differences in how the staff perceived these service providers.     

Predicting reading achievement in the first year of schooling: A comparison of readiness tests and instructional programs

Data from four reading-related tests, including a measure of knowledge about books and print conventions, and two demographic variables, obtained at the end of the first year of schooling, were used to predict a range of students' word and discourse reading achievement at the conclusion of that year. Students were enrolled in a reading program that emphasized either the subskills involved in breaking the reading code or the more holistic gaining of meaning from print. The results indicated that a measure of knowledge about books and print conventions is strongly related to end-of-year reading achievement, but that, over and above the other more traditional measures, it is a significant predictor of only one type of comprehension - that involving the inferential linking of two pieces of information separated in the text. Students in a subskills-emphasis program outperformed those in a meaning-emphasis program on tests of word knowledge but not of comprehension of discourse.     

Self-esteem and beliefs about memory in environmentally stable and relocated students

This research examined beliefs about the utility of environmental, semantic, and phonological cues for remembering, as these beliefs are related to feelings of self-esteem, assertiveness, and locus of control. We proposed different types of relationships between self-esteem (and assertiveness) and metamemory for two group of college students, based on their differential experiences with distinctive memory failures. For students who were familiar with their current environment, self-esteem was positively related to confidence in having a good memory. It was only for newcomers—students who had recently moved to a new environment—that beliefs about the benefits of environmental cues were positively related to self-esteem and assertiveness. These results suggested that if newcomers were less aware of the utility of environmental cues, they were more likely to attribute their memory failures to their own inadequacies. We also obtained evidence that subjects with an internal locus of control were more knowledgeable regarding the utility of environmental cues than were externally oriented subjects.
