A short version of a spatial activity questionnaire

Newcombe, Bandura, and Taylor developed a questionnaire measuring participation in space-related activities. The activities were classified as masculine, feminine, or neutral in gender stereotyping. A short version of this questionnaire was developed based on an item analysis of the responses by 485 introductory psychology students (236 women and 249 men). The 10 masculine, 10 feminine, and 10 neutral items chosen for the short form were given to 60 subjects (28 women and 32 men), along with a measure of spatial performance (Piaget's water-level task). Reliabilities (by coefficient alpha) were .79, .77, and .75, for the masculine, feminine, and neutral activity subscales, respectively. As with the original scale, women had a greater preference than men for feminine activities, men had a greater preference than women for masculine activities, and women and men had an equal preference for neutral activities. Masculine activity preference was associated with better water-level performance, with the relationship significantly stronger for women (r=.50) than for men (r=.10). Uses for the questionnaire in research on sex-related differences in spatial performance are suggested.     

Observer bias in scoring boys' and girls' aggression

In order to examine the possibility that the attribution of more aggression to boys may be in part a function of observer bias, 40 adults were asked in Study 1 to record the degree of aggression in a series of line drawings that showed children interacting. It was found that a significant subset of both males and females recorded more aggression for boys than for girls when they scanned scenes that showed numerous children interacting. When they rated a series of drawings of two children interacting, males rated boys as significantly more aggressive than girls. Study 2 examined 48 adults' responses under one of three instruction conditions. The findings of Study 1 were replicated. Additionally, it was found that some forms of instruction eliminate sex-typed biases while others yield significant biases among both male and female untrained observers. These results are interpreted in light of the literature on schematic processing. Implications pertaining to the socialization of aggression and to research on sex differences in aggression are discussed.     

Time reallocation in a multiresponse environment: Effects of restricting response classes

Four adult male rats were each placed for three hours daily into an apparatus that provided individual compartments for six separate location-defined responses. The available responses consisted of: (1) the opportunity to turn off room lighting, producing darkness; (2) the opportunity to view a female rat; (3) the opportunity to turn off white noise; (4) the opportunity to drink; (5) the opportunity to eat; and (6) "other," representing time in the hallway between compartments. Each subject underwent a series of conditions characterized as an A-B-A-C-A design. Manipulations consisted of the removal of a low-probability response (darkness) and of a high-probability response (escape from noise) in a counter-balanced manner across subjects. The dependent measure for all subjects was the percentage of total session time spent in each compartment. Four predictive rules concerning the redistribution of behavior after response restriction were tested, including the constant-ratio rule, equal time redistribution, the most probable alternative, and the sequential-dependency rule. The results indicate no support for any of the four predictive rules and suggest that empirical assessment of restriction effects is necessary in reinforcement studies involving temporally extended responses.     

Decisional processing in paranoid and non-paranoid schizophrenics

40 schizophrenic subjects, divided into paranoid/non-paranoid categories and 14 normal controls were presented a task which involved making "same-different" judgments during random presentations of a series of visual comparison stimuli with a standard which represented the midpoint of the stimulus continuum. Using Sternberg's Choice RT paradigm for studying the locus of cognitive deficit, difficulty at the response-selection stage was manipulated while holding other stages constant. It was predicted that paranoids would have shorter RTs at easy decision points and longer RTs at difficult decision points relative to non-paranoids. The directions of the differences were as predicted but did not attain statistical significance. Both schizophrenic groups, compared to normals, made significantly fewer "same" responses on those trials where the comparison and standard were most similar.     

Investigations of a mirror-image transfer effect in pigeons

In two separate experiments, pigeons trained binocularly to peck a key on which an oblique line (e.g., 60 degrees counter-clockwise rotation from horizontal) was projected yielded bi-modal angularity generalization gradients in extinction, with peaks of responding at both the training stimulus and its mirror image (in this case 120 degrees ). This mirror-image transfer effect may be analogous to an "octave effect" in auditory generalization, but Mello's finding of a mirror-image reversal transfer effect following monocular training in pigeons suggests an alternative interpretation.     

APPLICATION OF A SOCIAL SKILLS TRAINING PROGRAM IN THE MODIFICATION OF INTERPERSONAL DEFICITS AMONG RETARDED ADULTS: A CLINICAL REPLICATION

Six mentally retarded adults, equally divided into two treatment groups, were provided with individualized social skills training programs. Treatment, evaluated via a multiple-baseline design strategy, was sequentially and cumulatively applied across target behaviors over a four-week intervention period. Behavioral observation probes and social validation measures served as the primary dependent variables. Results indicated that (a) treatment was effective for virtually all behaviors across all subjects, (b) improvements occurred for both training and generalization scenes, and (c) behavioral performance was maintained one month following the termination of treatment.     

Reexamining the demand for HR certification in the United States

Given the addition of new Human Resources (HR) certification offerings by the Society for Human Resource Management and the increase in HR certifications being awarded by the HR Certification Institute, it is necessary to investigate the current rate of demand for HR certification and explore practical implications for those within the field. The current study analyzed over 5,300 HR job announcements and found 20.7% demanded (preferred and/or required) HR certification with more requiring HR certification than before. Additionally, HR certification demand was positively related to salary, experience, education level, and job title with demand reaching 33.7% for managerial HR roles.
