The cognitive basis of the comprehension and production of relational terminology

The comprehension of big, little, and same number and the productio of relational terminology was assessed in 168 preschool children. Stimuli were used which varied the relationships of length, number, and density. Language comprehension and production were related to the complexity of cognitive operations required by the task. Specifically, comprehension was easier in the situations in which length and number were positively correlated than when length provided no cue to number. Comprehension was most difficult when length and number were negatively correlated. There was asymmetry in language comprehension such that the positive term big, was comprehended earlier than little in some tasks; there was also asymmetry in production in that the child was more likely to use language related to the positive pole than to the negative pole. These data were interpreted as providing support for theories of the cognitive basis of language acquisition.     

Absolute identification of notes and intervals by musicians

Speech sounds are judged reliably and absolutely, while the judgment of nonspeech stimuli, such as tones, is thought to be unreliable and dependent on contextual cues. Here we demonstrated that the judgment of tonal stimuli may also be reliable and absolute, provided that the subjects are trained musicians. In Experiment 1, musicians with relative pitch identified 21 tonal intervals ranging from unison to major third, and the resulting identification functions were similar to those that have been previously obtained for speech. In Experiment 3, the judgment of intervals by musicians was shown to be free of context effects, since the best subjects gave virtually identical judgments to the same intervals in two stimulus contexts. Similar results were obtained in Experiments 2 and 4 for the judgment of single tones by possessors of absolute pitch. Performance with both notes and intervals by nonmusicians, however, was unreliable and greatly influenced by context. These findings suggest that musicians acquire categories for pitch that are functionally similar to phonemic categories for speech     

Note on the computation of biserial correlations in item analysis

A rapid method is described for machine computation of biserial correlations in item analysis with several criteria. This method has been found to yield biserial correlations from punched IBM cards at the rate of about 41 per hour.     

Psychometric evaluation of the Menstrual Joy Questionnaire

Analysis of 10 terms in the Menstrual Joy Questionnaire of Delaney, Lupton, and Toth indicated that the 34 undergraduate students did not agree on the definitions of scale items. The authors discuss the use of this questionnaire as a stimulus in experimental research and as a measure of positive perimenstrual experience.     

Criteria used in the selection of students for school psychologist training programs

A questionnaire regarding criteria used in the selection of students for school psychologist There were 63 responses. Undergraduate scholastic index was the most frequently used criterion, followed by undergraduate psychology index, letters of recommendation, and GRE scores. The interview, used by half of those reporting, was not employed consistently. The MAT was used by less than half of the respondents, and ranked lower in importance. Most universities used four or five criteria for admission. No respondents required teaching experience.     

Stressful life events and use of physician services among the elderly: the moderating role of pet ownership

The physician utilization behavior of 938 Medicare enrollees in a health maintenance organization was prospectively followed for 1 year. With demographic characteristics and health status at baseline controlled for, respondents who owned pets reported fewer doctor contacts over the 1-year period than respondents who did not own pets. Furthermore, pets seemed to help their owners in times of stress. The accumulation of prebaseline stressful life events was associated with increased doctor contacts during the study year for respondents without pets. This relationship did not emerge for pet owners. Owners of dogs, in particular, were buffered from the impact of stressful life events on physician utilization. Additional analyses showed that dog owners in comparison to owners of other pets spent more time with their pets and felt that their pets were more important to them. Thus, dogs more than other pets provided their owners with companionship and an object of attachment.     

Characteristics of the indirect McCollough effect

Induction of contingent color aftereffects with a single chromatic grid sometimes results in an illusory color on a grid different from the one presented during induction. Such illusory color, contingently elicited by a noninduced grid, has been termed the indirect McCollough effect (indirect ME). We show that the indirect ME occurs only when the color complementary to the grid color is present during induction (either physically present or as a color afterimage), and that the indirect ME is seen only on gratings that are orthogonal to the induction orientation. These findings are in accord with the account of the indirect ME proposed by Humphrey, Dodwell, and Emerson (1989). We also show that characteristics of the indirect ME (seen following one-grid induction), both on induced and orthogonal orientations, are similar to those observed with the direct ME (seen following the usual two-grid induction procedure). Both procedures result in contingent aftereffects that display substantial retention and that do not display interocular transfer.     

Elevation: A review of scholarship on a moral and other-praising emotion

The term elevation (also referred to as moral elevation), described by Thomas Jefferson and later coined by Jonathan Haidt, refers to the suite of feelings people may experience when witnessing an instance of moral beauty. The construct of elevation signifies the emotion felt when a person is a witness to, but not a recipient of, the moral behavior of others. Scholarship examining elevation has burgeoned since Haidt first introduced the construct. Researchers have explored the antecedents of, and outcomes associated with, witnessing instances of moral beauty. The current review will outline the existing scholarship on elevation, highlight conflicting findings, point out critical gaps in the current state of elevation research, and delineate fertile future directions for basic and applied research. Continued investigation of the affective, motivational, and behavioral responses associated with witnessing virtuous actions of others is warranted.
