The control of visual attention using multiple target features

An experiment was conducted to determine how visual attention is allocated in response to pairwise combinations of location, color, and size cues. Subjects viewed displays of eight letters arranged into an 'X' pattern emanating from a central fixation point. The letters varied on the dimensions of location (foveal or parafoveal positions), size (large or small), and color (red or blue). Seven of the letters were 'X's and the remaining, critical letter was either an 'R' or an 'L'. Subjects were given advance cues about characteristics of the critical letter on two of the three dimensions (location size, and color). The cues varied in their validity such that on any trial either both dimensions were validly cued, one dimension was validly cued while the other was invalidly cued, or both cues were invalid. Subjects were instructed to try to use the cues to find the critical letter, and response times to identify it as an 'R' or an 'L' served as the main dependent measure. Two models were evaluated against the data; in one, location cues are viewed as having distinct effects on an early stage of attention whereas color and size cues operate only in a later, selection stage. In the other model, all cues are used in a similar way to select display items for serial, focal attention. In general, the serial processing model provides a more complete account of the data.     

The effect of social support on adolescent mothers' styles of parent-child interaction as measured on three separate occasions

The purpose of this study was to determine the effect of social support on parent-child interaction in a group of 19 adolescent mothers. The subjects participated in a 20-week model demonstration program in which they worked in a preschool classroom with skilled caregivers who modeled facilitative styles of interacting with young children. Each subject was videotaped while interacting with a 1- to 2-year-old child upon entering the program, midway through the program, and at the end. Results showed that girls who were 16 years or older significantly increased their frequency of using responsive, engaging, and elaborative styles of behavior. Those under age 16 did not show significant changes in these three behaviors. Overall, subjects significantly increased the duration of time they spent observing the child's play behavior.     

Information search following damage to the frontal lobes

Five adult patients with focal brain damage in different areas of the frontal lobes and five matched controls were administered a 20 Questions test. Other tests of planning, problem-solving, and decision-making were also administered to frontal lobe patients. The results indicate that damage to the frontal lobe impairs the ability to impose and utilize hierarchical organization in mental representation.     

Having it all? Combining work and family in a male and a female profession

Are women in a female-dominated profession more successfully able to combine work and family obligations than women in a male-dominated profession? To explore this question, a comparison was made between the family status and careers of 747 women librarians (a female-dominated profession) and those of 449 women MBAs (a male-dominated profession). It was expected that the librarians would marry earlier and have more children. This general prediction was not supported. Over half of both groups of women were married, and after controlling for age, there were no differences in number of children. However, many women without children in both groups reported that they would like to be mothers. This disparity between wanting children and not having them was more common for women MBAs than women MLSs. MBAs and librarians were about equally likely to have had job interruptions, but librarians were more likely to have worked part-time. Reasons for an interruption to full-time work were as likely to be for problems finding (full-time) work as for family responsibilities. Librarians' salaries were much lower, but job interruptions and part-time work had a more negative effect on the salaries of women in business. In sum, the data suggest that many of the women surveyed have not combined motherhood with a professional career and that it is probably somewhat more difficult to combine a family with a career in business than with a career in library science.     

Flexibility of Labor, Well-Being, and Stress

After a short introduction into the changing nature of our society and organizations, we outline two kinds of flexibility of labor: qualitative flexibility, that is the degree to which people who work in or for a certain organization can and do perform different tasks, and quantitative flexibility, that is, varying the quantity of personnel and their working hours. Then, the different ways in which we organize our work and organizations are dealt with in terms of quantitative and qualitative flexibility. Next, we survey these ways of organizing on the degree to which they moderate the positive individual outcomes, or individual goals, of work. It can be concluded that quantitatively flexible work, besides some minor positive consequences, may have serious negative consequences for one's well-being, health, and personal development, while qualitative flexibility may have many more advantages, though it may lead to a devastating task overload. Last, we explore some ways to alleviate these negative effects.     

The use of the occupational stress indicator (OSI) in factory workers in China

The purpose of the study was to investigate occupational stress among Chinese factory workers (N=342), from three cities of South East China, using the shortened version of the Occupational Stress Indicator (OSI)-2. The results showed that the reliabilities and predictive validity of the OSI-2 subscales and other subscales used for the study were reasonably high. Quite a high percentage of workers perceived high work pressure. The main sources of stress were intrinsic to the job; and the coping strategies that were most frequently used to tackle stress were “control” methods. In addition, “satisfaction on environmental condition” seemed to be a common predictor for job satisfaction, and mental and physical well-being. The logical relationships between job satisfaction, mental well-being and physical well-being in Chinese workers have provided support to the findings obtained in Western countries.     

Ninety-three pictures and 108 questions for the elicitation of homophones

Homographs and homophones have interesting linguistic properties that make them useful in many experiments involving language. To assist researchers in the elicitation of homophones, this paper presents a set of 93 line-drawn pictures of objects with homophonic names and a set of 108 questions with homophonic answers. Statistics are also included for each picture and question: Picture statistics include name-agreement percentages, dominance, and frequency statistics of depicted referents, and picture-naming latencies both with and without study of the picture names. For questions, statistics include answer-agreement percentages, difficulty ratings, dominance, frequency statistics, and naming latencies for 60 of the most consistently answered questions.     

Client preferences for informed consent information

Thirty-five current therapy clients, 47 former clients, and 42 college students with no therapy experience rated 27 items in terms of importance for inclusion in informed consent discussions. The current and former client samples rated information about inappropriate therapeutic techniques, confidentiality, and the risks of alternative treatments as most important, and information about the personal characteristics of the therapist and the therapist's degree as least important. The results of this study provide evidence for differential informed consent disclosure practices.     

Positive and Negative Hypothesis Testing by Cooperative Groups

In a rule induction problem positive hypothesis tests select evidence that the tester expects to be an example of the correct rule if the hypothesis is correct, whereas negative hypothesis tests select evidence that the tester expects to be a nonexample if the hypothesis is correct. Previous research indicates the general effectiveness of a positive test strategy for individuals, but there has been very little research with cooperative groups. We extend the analysis of Klayman and Ha (Psychological Review, 1987) of ambiguous verification or conclusive falsification of five possible types of hypotheses by positive and negative tests by emphasizing the importance of further examples following hypothesis tests. In two experiments four-person cooperative groups solved rule induction problems by proposing a hypothesis and selecting evidence to test the hypothesis on each of four arrays on each trial. In different conditions the groups were instructed to use different combinations of positive and negative tests on the four arrays. Positive tests were more likely to lead to further examples than negative tests, and the proportion of correct hypotheses corresponded to the proportion of positive tests, in both experiments. We suggest that positive tests are more effective than negative hypothesis tests in generating further evidence, and thus in inducing the correct rule, in experimental rule induction tasks with a criterion of certainty imposed by the researcher.
