Aging and autobiographical memory: dissociating episodic from semantic retrieval

Cognitive aging research documents reduced access to contextually specific episodic details inolder adults, whereas access to semantic or other nonepisodic information is preserved or facilitated. The present study extended this finding to autobiographical memory by using a new measure; the Autobiographical Interview. Younger and older adults recalled events from 5 life periods. Protocols were scored according to a reliable system for categorizing episodic and nonepisodic information. Whereas younger adults were biased toward episodic details reflecting happenings, locations, perceptions, and thoughts, older adults favored semantic details not connected to a particular time and place. This pattern persisted after additional structured probing for contextual details. The Autobiographical Interview is a useful instrument for quantifying episodic and semantic contributions to personal remote memory.     

Colour constancy in goldfish and man: influence of surround size and lightness

Colour constancy was investigated by using a series of 10 simultaneously presented surface colours ranging in small steps from green through gray to red-purple. Goldfish were trained to select one medium test field when the entire setup was illuminated with white light. In the tests, either red or green illumination was used. Colour constancy, as inferred from the choice behaviour, was perfect under green illumination when the test fields were presented on a gray or a white background, but imperfect on a black background. Under red illumination and a white background, however, colour constancy was overcompensated. Here, a colour contrast effect was observed. The influence of background lightness was also found when the surround was restricted to a narrow annulus of 4-11 mm width (test field diameter: 14 mm). By applying colour metrics it could be shown that the von Kries coefficient law can describe the overall effect of colour constancy. For an explanation of the effect of surround size and lightness, lateral inhibitory interactions have to be assumed in addition, which are also responsible for simultaneous colour contrast. Very similar results were obtained in experiments with the same colours in human subjects. They had to name the test field appearing 'neutral' under the different illumination and surround conditions, as tested in the goldfish experiment.     

Transparency and self-disclosure in family therapy: dangers and possibilities

Therapy is a paid intimate relationship that thrusts clients and therapists into navigating personal and professional boundaries. When, where, why, and how is it appropriate and ethical for family therapists to be transparent, and when is it damaging? Theorists take varied stances from Haley's position of tight boundaries around therapist disclosure—whether in treatment or training—to the narrative viewpoint that therapists should be transparent about models of therapy, personal values, and life experiences that inform their practice and beliefs. However, these positions are not research based, and theorists who support disclosure offer few guidelines other than general statements. This article examines the history of ideas about disclosure in six major family therapy models, and the dangers and possibilities of transparency. It looks at the research on self‐disclosure in individual therapy and whether and how it could apply to family therapy. Guidelines are proposed that take into account the multiple social identities of therapists and clients, and issues of safety and transparency.     

Students' perspectives on their high school experience

This study explored students' levels of belonging and engagement in high school by obtaining their perspectives on the instruction, teachers, friends, and activities in their school. We interviewed 33 students from seven comprehensive high schools in Richmond, Virginia. Students indicated that they were more engaged when the instructional program included authentic learning experiences, teachers who provided challenging activities and showed interest in student learning, and a school day that supported interpersonal relationships with peers and adults. It was concluded that, to promote belonging and engagement, school personnel should attend to the quality of student learning and relationships.     

TREATING SELF-INJURY: WATER MIST SPRAY VERSUS FACIAL SCREENING OR FORCED ARM EXERCISE

In three experiments, the effect of water mist spray on self-injurious and collateral behaviors was compared with either facial screening or forced arm exercise. Water mist spray was as effective as facial screening in suppressing face-slapping in Experiment 1. However, it was not as effective as facial screening for self-injurious finger-licking in Experiment 2 or forced arm exercise for excessive ear-rubbing in Experiment 3. These results suggest that while water mist spray is effective, it may be less so than alternative procedures. In Experiments 2 and 3 there was a consistent decrease in the occurrence of untreated maladaptive behaviors. In addition, there was a moderate increase in appropriate social interaction in Experiment 2 and a substantial increase in Experiment 3.     

The Impact of Leadership Style on Global Management Practices1

A study was conducted to explore the impact of differences in leadership style on the practice of global leadership and management. Data were collected from 391 senior managers from a global organization and 1,701 of their direct reports, 358 straight-line supervisors, and 266 dotted-line supervisors. ANOVA results indicate that transformational leaders were rated significantly higher on all behaviors by their direct reports than were transactional leaders. Straight-line supervisors rated transformational leaders significantly higher on managing change- and relationship-management behaviors, whereas dotted-line supervisors rated transformational leaders higher on learning orientation. Finally, transformational leaders were significantly more self-aware (greater congruence in self vs. direct reports' average ratings) regarding the practice of these behaviors. implications for future research are discussed.     

Personality correlates of career choice in the Kibbutz: A comparison between career and noncareer women

The study compared Kibbutz career women (who studied beyond high school and worked in their profession) to Kibbutz noncareer women (who did not study beyond high school and worked in various nonprofessional jobs such as the laundry, the kitchen, and child care) on several personality characteristics. All subjects were nonorthodox Jewish women who were born and raised in the Kibbutz. The two groups completed a variety of self-report inventories, including the Bem Sex-Role Orientation Inventory, need for achievement inventory, two self-esteem scales that measured both the global self-esteem and various dimensions of self-esteem (academic, social, physical appearance, physical abilities, and self-regard) and Cattell's Clinical Analysis Questionnaire (CAQ), which is a short version of Cattell's 16 Personality Factors Test. The results showed that Kibbutz career women differed significantly from noncareer women on several personality characteristics. These women attributed to themselves more instrumental characteristics, were found to be more independent and emotionally stable, and had a higher need for achievement and a higher academic and social self-esteem. In addition, the division of household work was more egalitarian in the case of career women. The results are discussed in view of the fact that all of the career women were actually holding traditionally feminine positions such as teachers and social workers.     

Effect of surface characteristics and style of production on naming and verification of pictorial stimuli.

Theories of object recognition that are based purely on part decomposition do not take into account the role of textural, shading, and color information, nor do they differentiate between stylistic factors in the preparation of line-drawn pictorial stimuli. To investigate these factors, naming and verification experiments were performed using line drawings, monochrome photographs, and color photographs of common objects. For line drawings, it was shown that line width, exposure, and contrast affected naming latency, which increased for lines of narrow width and extremes of exposure. Naming latencies were compared for objects drawn by a professional artist, with varying degrees of surface detail, and objects produced by a computer-aided design (CAD) system, with no surface detail. The mean naming latencies for the artist set were faster than for the CAD set, though not significantly, with a significant degree of object correlation being observed. However, in certain cases there were significant differences between objects. These were investigated in a further experiment in which subsets with common properties of present or absent surface detail were selected from the artist-drawn stimuli. It was found that the presence of surface features resulted in lower response latencies even for those objects that intuitively could be recognized by parts alone. The time to name photographic and line-drawn stimuli was compared, and a progressive decrease in naming latency from line to monochrome to color stimuli was observed. In a verification task, no significant advantage for color or monochrome photographs over line drawings was found, either when comparing stimuli of equivalent or of different mode. However, there was a tendency for the comparison of different modes to take longer than the comparison of same modes. The results are discussed in terms of theories of human visual processing and cognitive and computational models of object recognition.
