Part—whole information is useful in visual search for size × size but not orientation × orientation conjunctions

In visual search tasks, subjects look for a target among a variable number of distractor items. If the target is defined by a conjunction of two different features (e.g., color × orientation), efficient search is possible when parallel processing of information about color and about orientation is used to “guid” the deployment of attention to the target. Another type of conjunction search has targets defined by two instances of one type of feature (e.g., a conjunction of two colors). In this case, search is inefficient when the target is an item defined by parts of two different colors but much more efficient if the target can be described as a whole item of one color with a part of another color (Wolfe, Friedman-Hill, & Bilsky, 1994). In this paper, we show that the same distinction holds for size. “Part— whole” size × size conjunction searches are efficient; “part-part” searches are not (Experiments 1–3). In contrast, all orientation × orientation searches are inefficient (Experiments 4–6). This difference between preattentive processing of color and size, on the one hand, and orientation, on the other, may reflect structural relationships between features in real-world objects.     

Overcoming Self-Negation in Women

The significant overrepresentation of women in depression and a seeming addiction to self-downing are viewed as heavily influenced by internalized gender role messages and further compounded by societal discrimination. The healthy self is defined, and ways of helping women in therapy move toward greater self-acceptance are described, with an emphasis on REBT women's groups. A case study illustrates the process.     

Legitimizing the Leader: Endorsement by Male Versus Female Authority Figures

Subjects viewed a videotaped group discussion by a leader and four other group members and evaluated each of them for leadership competence. The leader, either a man or a woman, was either personally endorsed ("legitimized") or unendorsed by either a male or a female authority figure. Legitimation raised both leaders' performance evaluations. Legitimation by the female authority affected the leaders' evaluations, overall, as much as legitimation by a male authority. For the male leader, legitimation by the male and female authority figures produced equal impact. However, legitimation by the female authority figure produced significantly greater impact on evaluations of the female leader's performance than the same legitimation by a male authority figure. The data suggest that female authority figures can be effective legitimizers of both sexes, but male authority's endorsements of a female subordinate may be viewed as suspect.     

Limitations on the parallel guidance of visual search: color x color and orientation x orientation conjunctions

In visual search for a conjunction it is much more difficult to search for the conjunction of 2 colors or 2 orientations than for Color x Orientation or Color x Shape conjunctions. The result is not limited to particular colors or shapes. Two colors cannot occupy the same spatial location in Color x Color searches. However, Experiments 6 and 7 show that Color x Shape searches remain efficient even if the color and shape are spatially separated. Our guided search model suggests that in searches for Color x Shape, a parallel color module can guide attention toward the correct color, whereas the shape module guides attention toward the correct shape. Together these 2 sources of guidance lead attention to the target. However, if a target is red and green among red-blue and green-blue distractors, it is not possible to guide search independently toward red items and green items or away from all blue items.     

Differences in abstraction ability with age

Three tests of abstraction were administered to 89 optimally healthy subjects aged 30-79. Performance on all 3 tasks showed significant differences with age. This was primarily, although not entirely, the result of deficits in performance by the 70-year-old subjects. These results do not appear to be related to changes in memory ability or to a differential increase in a particular type of abstraction error.     

Speaking without seeing,or the effect of interviewer absence on interviewee disclosure time

The results of the present study confirmed earlier findings that the elimination of the usual face-to-face confrontation between interviewer and interviewee enhances disclosure time in relation to intimate questions. By unconfounding speaking time and pausing time, the present research demonstrated that the facilitating effect of an interviewer's absence is not simply an artifact of increased latencies and silent pauses within responses. The earlier findings were extended by manipulating the intimacy level of questions asked of subjects in the context of a gender-balanced design.     

Effects of mutual invisibility and topical intimacy on verbal fluency in dyadic communication

The mutual reduction of visual feedback, which in this study did not interfere with the synchronization of turns, reduced the productivity levels and increased the silent pauses of female speakers, even though it had no effect on their subjective discomfort, anxiety, and ease of communication self-ratings. The same reduction of visual feedback, which was achieved by seating the participants back-to-back rather than face-to-face, caused male speakers to feel anxious and uncomfortable and reduced the duration of their silent pauses, but only in samegender dyads. These findings are explained in terms of previously noted gender differences in the need for visual feedback and in the anxiety-arousing effects of back-to-back interactions. Intimate communications, on the part of both male and female speakers, were associated with a slow pacing of speech but not with a decrease in productivity level, independently of the seating arrangement. These findings are interpreted in terms of the self-monitoring and self-censoring that is usually associated with the communication of intimate messages.     

Postnatal development of heart rate patterns elicited by an aversive CS and US in cats

Heart rate and motor responses were recorded in cats of different ages during classical conditioning. A deceleratory-acceleratory heart rate pattern observed during the CS-US interval in one and four-week-old kittens is an alpha conditioned response, a potentiated original response to the CS. At eight weeks of age two new distinct patterns of pure acceleration or pure deceleration are acquired during conditioning and in the absence of motor learning. At 12 weeks of age and in adult subjects, heart rate patterns during the CS-US interval become more complex and conditioned motor responses can be observed. A covariance of HR acceleration and motor responses during the CS-US interval is absent in eight-week-old subjects, but quite high in 12-week-old subjects and adult cats. The data are interpreted as suggesting separate elicitatory mechanisms of HR and motor responses which may show synchrony later in ontogeny.     

The effect of organizational identification on employee affective and performance responses

Organizational identification (OI), defined as the importance of the organization in the person's self-concept, was argued to influence employee affective responses (job satisfaction and alienation) and performance responses (task involvement, investment of effort, and performance effectiveness). More specifically, it was hypothesized that there is 1. a positive relationship abetween OI and satisfaction with five job dimensions-work, supervision, pay, promotion and co-workers; 2. a negative relationship between OI and alienation; and 3. a positive relationship between OI and three task-related variables-task involvement, investment of effort, and performance effectiveness. A survey study was conducted on 215 service deliverers to the elderly in a large midwest city. The results were mostly consistent with the hypotheses.The data for this study was collected under the auspices of theBenjamin Rose Institute, Cleveland, Ohio.     

TEACHER POPULARITY AND CONTRAST EFFECTS IN A CLASSROOM TOKEN ECONOMY

There is a common fear that the use of a token economy in one classroom might harm pupil performance in situations where the contingencies are not in effect. This study investigated potential contrast effects on measures of children's productivity and attitudes toward teachers. Six children with reading deficits participated. A multiple baseline design was used to assess the effects of a token economy which was systematically introduced across three teachers. Dependent measures included two rating forms of teacher popularity and work rate on a programmed reading series. The results indicated that the token system was effective in increasing the children's productivity and that no consistent behavioral contrast effects occurred. Furthermore, children's attitudes toward teachers did not appear to be influenced by the token economy until only one teacher was not delivering tokens. At this point, her popularity declined until she also delivered tokens. The token economy manipulation appeared to have a specific, desirable effect on the targeted behavior (i.e., work rate) and had minimal negative or positive “side effects” on teacher popularity.
