Traditionality of choice and sex-role identification as moderators of the congruence of occupational choice in college women

This study examined the relationship of traditionality of occupational preferences and sex-role orientation to personality-occupational environment congruence in college women. Three-letter Holland personality codes were obtained for each of 184 college women based on same-sex normative scores from the Strong-Campbell Interest Inventory and on scores from the ACT Unisex Interest Inventory (UNIACT). Subjects' occupational preferences were classified as traditional, moderately traditional, or nontraditional based on the percentages of women in the occupation. Scores on the Bern Sex Role Inventory were used to classify subjects into one of four sex-role categories. Results indicated a strong association between congruence and traditionality of choice; women whose choices were in nontraditional career fields were significantly more likely to be making choices congruent with their personality type than were women choosing traditional career fields. Further, while sex-role orientation was not significantly related to either congruence or traditionality, masculine-typed women were most likely to make nontraditional and congruent career choices, while the majority of feminine-typed, androgynous, and undifferentiated women stated preferences for traditional career fields. Implications for the applicability of Holland's congruence postulate to women's vocational behavior are discussed.     

Sources of error in the psychoeducational diagnosis of children

A detailed exploration of the role of diagnostic practices is presented, with special attention given to such practices in school psychology. Basic principles related to diagnostic typology and concepts of reliability and validity are reviewed in the context of recent diagnostic decision-making research. Finally, the intrusion and eventual reduction of particular errors of consistency and inconsistency and psychodiagnosis are examined with a view toward improvements in future training and practice.     

Use of a statistical significance criterion in drawing inferences about hemispheric dominance for language function from dichotic listening data

A dichotic listening test (composed of VCV nonsense syllables) was administered to 31 right-handed subjects. A χ² statistical significance criterion was then applied to the resulting ear differences in subjects. Fifteen subjects had ear differences significant at the p < .10 levels. Of these, 14 had right-ear advantages, an incidence consistent with the incidence of left-hemisphere language dominance derived from neurological data. Incidence for the total group of 31 subjects, however, showed the overabundance of left-ear-superior protocols typical of studies that report ear-dominance scores with no statistical criterion.     

The modification of intelligence through early experience

Infants judged to be at risk for subnormal intellectual growth were randomly assigned to an Experimental (N = 27) or a Control (N = 25) group. Infants in both groups received medical care and dietary supplements; their families received social work services on a request basis. Experimental children participated in an educational daycare program beginning before the third month of life. The daycare program was composed, in part, of curriculum activities designed to stimulate intellectual growth. Between 6 and 36 months of age, Experimental children maintained normal intellectual growth; Control children declined in IQ beginning between 12 and 18 months of age and remained significantly lower than Experimental children at 24 and 36 months. The mother-child IQ correlation for Control dyads was 43; for Experimental dyads the correlation was ?.05. These two types of evidence are interpreted as support for the importance of early environments in the development of intelligence.     

Organizational features of a young child's behaviors

The study was designed to investigate the nature of response-class phenomena and the possibility of indirect contingency control. A single subject was employed. Prior to the start of the study, the experimenter established the process of maintaining stimulus constancy during a preexperimental phase. Subsequent to the first baseline phase, a factor analysis was done to define the response class and the behavior categories constituting the class. Manipulating a single adult consequence to a response-class category over subsequent baseline and manipulation phases revealed frequency changes in all behavior categories in the response class. The data gave support to indirect behavior control. Search for possible explanations of frequency changes showed that the direction of the frequency changes were predictable from the results of the factor analysis.     

Part-whole transfer and organization in children's and adults' multitrial free recall

The effect of age-related differnces in the use of recall organization on the amount of recall and the properties of recall-acquisition patterns obtained in a multitrial part-whole transfer task was investigated among subjects in grade levels 1, 4, 7, and college (ages 6.5, 9.6, 12.6, and 19.7 years, respectively). Half of the subjects receiving relevant and irrelevant part lists sorted stimuli before recall trials; other subjects studied the items as they were presented, one at a time. Relevant part list learning was equally facilitative for all age groups regardless of presentation condition, and despite the greater amounts of recall organization found among college subjects. All age groups showed trial-to-trial improvements in whole-list recall; however, only the college subjects showed corresponding improvements in clustering, and all age groups had high rates of fluctuation in the composition of their recall from trial to trial. It was concluded that while even the limited amounts of spontaneous recall organization found among children are sufficient to enhance recall, organization is not a necessary condition for recall improvement and not the primary means by which children throughout the preformal-operations period increase their recall of unrelated stimuli over trials in a free-recall task.     

The effects of intrinsic and extrinsic rewards in a risk-taking situation

This study varied both the intrinsic and extrinsic rewards associated with performing a task in a risk taking situation. When the task performed to win a prize provided little if any intrinsic reward, subjects liked and tried for prizes that were easy to obtain. In contrast, when the task was intrinsically rewarding, subjects liked and tried for those prizes that were somewhat more difficult to obtain. In addition, subjects were more likely to like and try for prizes easier to obtain when the extrinsic reward was high.     

Developmental differences in subjects' associative-learning strategies and performance: Assessing a hypothesis

Fifth-, seventh-, and ninth-grade (11-, 13-, and 15-year-old) subjects were presented with a list of paired associates to learn and were interviewed about the strategies used to learn them. Although a majority of fifth graders reported simply rehearsing the pairs in order to remember them, very few ninth graders relied exclusively on rehearsal. Consistent with a hypothesis advanced by Rohwer (1973), the number of subjects who elaborated some or all of the pairs increased with age. Paired-associate performance increased with age, but the level of paired-associate learning was much more related to the type of strategy reported by the subject than to the age of the subject per se.
