Assessing gender-related differences in achievement orientation using two different achievement scales

The consistent finding that the achievement scales of the Adjective Check List (ACL) and Edwards Personal Preference Schedule (EPPS) are not correlated has led researchers to question the validity of both of these measures. This article presents evidence indicating that although these measures are independent, they can predict the same performance criteria. Of interest is that the EPPS predicts outcomes for men, whereas the ACL predicts performance for women. A topical examination of each measure's relationships to other scales provides a tentative rationale for these scales' orthogonality that does not call into question the validity of either measure.     

Psychodiagnostic test usage: a survey of the society for personality assessment

The present survey investigated psychodiagnostic test usage and practices of the Society for Personality Assessment. A brief questionnaire was forwarded to 400 SPA members and 206 responded for a 51.5% rate of return. Projective techniques found popular in previous surveys of Division 12 were the major assessment instruments utilized by SPA members. Exner's comprehensive system was the preferred mode of Rorschach analysis, followed by the Klopfer and Beck systems. The Wechsler Scales and the MMPI were frequently included in conducting a psychological battery. Personality assessment was mainly utilized for diagnostic purposes and as an indicator for type of therapy.     

Visual movement discrimination

Data are presented which support a mathematical model for visual movement perception. An observer’s ability to judge the relative position of two successively presented points of light in an otherwise dark room is shown to diminish as the inter-stimulus interval is increased. However, a measure of visual position memory appears to remain invariant a5 this interval is varied. Neither the degree of head stabilization nor whether viewing is monocular or binocular appreciably alters this measure.     

Children's acquisition and reversal behavior in a probability learning situation as a function of programed instruction,internal-external control,and schedules of reinforcement

A three-choice, contingent task was used with 192 fifth and sixth graders in a 2 × 2 × 3 factorial design combining instruction (programed instruction on selected probability concepts vs no programed instruction), locus of control (internal vs external), and schedules of reinforcement (33, 66, and 100%). The dependent measures were the percentage of correct acquisition responses, of correct reversal responses, and of pattern responses, as well as posttests on probability concepts. The major findings of the study were associated with schedule of reinforcement. In acquisition and reversal, Ss under 100% reinforcement during acquisition tended to maximize the greatest, followed by the 66 and 33% conditions, in that order. The ordinal relationship among schedules was the exact reverse of the maximizing approach for the pattern responses. A partial reinforcement effect was obtained in reversal. Evidence indicated that programed instruction and locus of control affected maximizing behavior, patterning behavior, and resistance to extinction (though these variables did not interact with reinforcement schedule in the predicted direction). Finally the posttest data showed that instructed Ss did learn more relative to noninstructed Ss.     

TRANSFER BETWEEN RECEPTIVE AND PRODUCTIVE LANGUAGE IN DEVELOPMENT ALLY DISABLED CHILDREN

The purpose of this study was to examine the relationship between receptive and productive language acquisition in developmentally disabled children. A single-subject operant methodology was employed to evaluate the effect of training in one mode on performance in the other mode. Noun labels for pictured objects were used as the unit of analysis. Six children with severe language deficits participated in the experiment. Each subject learning to identify a different set of five pictures in each of four successively administered training conditions. In the first condition, a set of pictures was trained in the productive mode. In the second condition, a different set was trained in the receptive mode. These training conditions were then repeated using two additional sets of pictures. Training was done using reinforcement for correct responses and prompting for incorrect responses. Nonreinforced probes were conducted throughout training to assess performance in the untrained mode. The pictures in each set were trained successively so that transfer across the language modes could be studied separately for each response trained. All subjects successfully met the criteria for learning each picture set in both the receptive and productive training conditions. The probe data showed that opposite-modality performance improved as a function of both types of training, although performance levels differed. After productive training, five of six subjects' performance was highly accurate on receptive probes. By contrast, receptive training resulted in limited correct productive performance. Transfer from receptive training was negatively related to subjects' use of extra-experimental labels on productive probe trials. In addition to these competing response errors, subjects frequently made articulation errors. The findings suggest that for retarded children similar to those studied here, productive training will be sufficient to establish accurate receptive performance on vocabulary tasks. However, receptive training does not appear to be either a necessary or a sufficient condition for productive performance. The results do not support the reception-then-production training sequence based on normal language development.     

Retrieval processes in fifth graders and adults

This research was concerned with retrieval processes which underlie conceptual clustering. In a free recall task with categorized lists, fifth graders' and adults' retrieval was examined temporally by means of interword response times. List organization and retrieval cue factors were manipulated in order to assess the developmental relevance of an hypothesized three component retrieval model. The results indicated that both age groups used a qualitatively similar retrieval strategy, involving search for and decoding of higher-order memory units. Providing retrieval cues eliminated the category search component, but also increased the likelihood of exhaustive recall attempts under random presentation conditions. The results were discussed in terms of the inter-relationships between storage and retrieval strategies. Age-related differences in retrieval time were attributed to insufficient reorganization during input and failure to attempt to recall all of a category's members.
