Gender Differences in Pointing Accuracy in Computer-Simulated 3D Mazes

Gender differences in pointing accuracy incomputer-simulated mazes were studied as a function ofmaze complexity and training effects. College students(primarily White) were led through mazes with different numbers of turns; at the end of each maze, theywere asked to indicate the direction of the maze origin(starting point). Pointing accuracy declined with numberof turns, but men were consistently more accurate than women by about 20°,regardless of maze complexity. Training participants totrack the relative position of the maze origin whilemoving through the maze produced equivalent benefits inpointing accuracy for both women and men. Thus, althoughpointing accuracy of men remained higher than that ofwomen, the results suggest that pointing performance canbe modified by experience.     

Issues in the psychological assessment of preschool children

This article discussed two issues relating to assessment of preschool children: (1) whether assessments of children of this age should be attempted, and (2) the issue of what is a “good” assessment. The general impression from a review of the literature and from personal experience is that preschool assessment is desirable and can be useful, but only under conditions which avoid labeling and attempt to circumvent and reduce the problems of reliability and validity, taking into consideration the interacting variables of the child, the task, and the setting.     

Extracting identity and location information from briefly presented letter arrays

The effect on identification and location of briefly presented targets (letters and blanks) of number of targets, retinal location, and direction and distance of simultaneously presented targets is investigated. In three different conditions, one, two, or three targets are presented on a trial with the location of targets varying from trial to trial. A model is proposed to describe identification and location performance in the one-letter condition. This model distinguishes between two sets of parameters, perceptual parameters and decision parameters, and assumes that in terms of these parameters, identification and location are independent processes. The perceptual and decision parameters of the model, estimated by assuming that these parameters are linearly related to retinal location, indicate that retinal location has a different effect on the decision parameters for both identification and location than on the perceptual parameters. Variables affecting the performance decrements found when multiple letters are presented are evaluated in terms of models stated for the multiple letter conditions. Estimates of the effects of distance from the fixation point and inter-letter distance indicate that, as both of these variables increase, performance decreases. In the three-letter condition, a serial position effect is found, with performance on center letters being relatively poor. A peripherally presented letter is found to have a large detrimental effect on performance, and the effect increases as interletter distance increases. Location of correctly identified targets follows many of the same patterns as identification performance in the multiple letter conditions. In addition, there is a tendency for incorrectly located targets to be moved foveally and to move to positions occupied by other targets on the trial. The possibility of a limited-capacity attention mechanism operating in the present experiment is discussed.     

Training in the use of double-function terms

Twenty first-, second-, and third-grade chidren were tested, trained, and retested in their use of double-function words (e.g.,hard, deep, bright). Children first understand such words as they refer to inanimate objects, then to people in a physical sense, and last to people in a psychological sense. Wide variations in initial understanding and trainability of double-function words occurred. It is easier to train children to understand a double-function words as applied to a person in a physical sense than in a psychological sense. Words with tactual referents (sweet, warm, dry, cold, hard) are understood earlier than words with visual referents (bright, crooked, sharp, deep) but words with visual referents show greater gains after training. Several possible explanations of these results are discussed.     

Effects of semantic and cheremic context on acquisition of manual signs

In two experiments, sign-naive subjects acquired the meanings for manual signs of American Sign Language by learning to respond with the English word equivalents when signs were presented. The results showed that when the signs on a to-be-learned list were related to each other in handshape configuration (cheremically similar), they were more difficult to acquire than when semantically similar. Whether the similar signs were grouped together during presentation or were separated by other dissimilar signs had no effect on the number of signs correctly acquired. These results were the same for the identical signs learned in the cheremically or semantically similar contexts as for the fists as a whole. The results have implications for teaching sign language to hearing adults.     

Divergent Perceptions of Jail Inmates and Correctional Officers: The “Blame the Other-Expect to Be Blamed” Effect1

Inmates and correctional officers in a Lwnty jail made attributions of responsibility and predicted each other's attributions in response to four hypothetical stimulus incidents varying in severity of the inmate's intentional misbehavior and the severity of the officer's intentional retribution. When the misbehavior and retribution were moderate, subjects blamed both participants about equally. However, both over- and underreactions to the stimulus inmate's misbehavior elicited defensiveness, with both officers and inmates more likely to attribute responsibility to their opposite role character. In addition, both inmates and officers appeared to respond defensively to severe but equitable retributions. Subjects blamed each other, and, anticipating the other's defensiveness, expected to be blamed. Examination of the data suggested that subjects may have responded stereotypically rather than empathetically, and that defensiveness impeded rather than facilitated predictive accuracy. Results were consistent with previous research, increasing the generality of the “blame the other-expect to be blamed” effect. Additional analyses indicated that inmates were more likely than officers to notice mitigating circumstances when considering the inmates' responsibility. Three recommendations were made which may help to forestall inmate reactivity to retributions: (1) Jail personnel should have objective and clear definitions as to what constitutes major and minor infractions; (2) inmates should be aware of these criteria; and (3) jail personnel should be sensitive to mitigating circumstances and moderate their retribution or anticipate possible reactivity from inmates.     

Effects of dominance cues on attributions of sexual behavior

Many writers have suggested that dominance plays an important role in human sexuality. This proposition was examined by asking 51 females and 85 males to rate their impressions of a man and woman (photographed in the nude) who were described as having a male-dominant, female-dominant, or equalitarian relationship. Results indicated that although subjects' level of sexual arousal was unaffected by dominance, dominant individuals were perceived as more sexually active than the other stimulus persons. As expected, dominance appeared to enhance perceived masculinity, while submissiveness increased perceived femininity. Surprisingly, dominant male and female stimulus persons were not differentially evaluated. These findings were interpreted as being consistent with the assumption dominance is positively associated with sexuality.     

Needs assessment activities in school psychology program development

Needs assessment activities are presented as a basis for gathering information essential to program development, revision, and evaluation. Needs assessment activities include surveys of trends advocated by national authorities and consumers and identification of needs of students and local school systems. These data form the basis for developing program objectives in a sequentially ordered multilevel program.     

Articulatory organization in the prefix effect

Neisser, Hoenig, and Goldstein (1969) reduced the “stimulus prefix effect” (diminished recall of seven digits preceded by a redundant prefix) when the redundant prefix and the recall digits were produced by different speakers. In the present studies, similar results were obtained using one speaker only, but with the prefix and recall digits spoken separately in different utterances and combined by tape splicing. The results support a hypothesis concerning the perception of intact, wholistically organized articulatory units. A second hypothesis, also based on the idea of intact articulatory units, was tested.
