The lost e-mail method: Milgram’s lost-letter technique in the age of the Internet

We examined Milgram’s (1977) lost-letter technique using e-mail. In the first experiment, 79 college faculty received mock lost e-mail messages. Nineteen percent of those who received the messages responded, in all cases by returning the message to the “sender” instead of forwarding it to the “recipient.” In the second study, attitudes toward presidential candidate Ross Perot were examined by sending out two different messages to 200 randomly selected e-mail addresses in the United States. Although there was no differential response rate, examination of content revealed attitudes consistent with concurrent poll data.     

SPREADING OF VISUAL ATTENTION TO MODALLY VERSUS AMODALLY COMPLETED REGIONS

Abstract— Regions of objects that are partially obscured at the current retinal image are often perceptually filled in by the visual system (Kanizsa, 1979). In some cases (modal completion), this causes the filled-in region to appear tinged with the color and brightness of unobscured parts of that object, but m other cases (amodal completion), it does not (Michotte & Burke, 1951). It has recently been argued that modal and amodal completion both arise in preattentive vision, and may operate equivalently at that level (Davis & Driver, 1994, He & Nakayama, 1992, Shipley & Kellman, 1992). In this article, we show that they have different effects on attentive vision, with attention tending to spread to (and from) modally completed regions and their visible inducers, but not to (or from) comparable amodally completed regions and their inducers. This finding is consistent with visual attention operating on surfaces (e g, He & Nakayama, 1995) in a viewer-centered representation of the scene, after the operation of filling-in processes.     

The value of possessions in compulsive hoarding: Patterns of use and attachment

Hoarding behavior, patterns of use of possessions, and emotional attachment to possessions were examined among a sample of female undergraduates and a sample of community volunteers. Hoarding behavior was associated with a decreased frequency of use of possessions and excessive concern about maintaining control over possessions. Furthermore, high scores on the hoarding scale were associated with higher levels of perceived responsibility for: (1) being prepared; and (2) the well-being of the possession. Hoarding was also associated with greater emotional attachment to possessions and to the reliance on possessions for emotional comfort. The implications of these findings for the definition of hoarding are discussed.     

Marriage and Family Counseling

This article provides an overview of marriage and family counseling, including the growth and interest of this specialty within the American Counseling Association (ACA). Areas discussed include the evolution of marriage and family counseling within ACA, standards for training, credentialing, and unique ethical considerations when counseling couples and families.     

Edge-Assignment and Figure–Ground Segmentation in Short-Term Visual Matching

Eight experiments examined the role of edge-assignment in a contour matching task. Subjects judged whether the jagged vertical edge of a probe shape matched the jagged edge that divided two adjoining shapes in an immediately preceding figure–ground display. Segmentation factors biased assignment of this dividing edge toward a figural shape on just one of its sides. Subjects were faster and more accurate at matching when the probe edge had a corresponding assignment. The rapid emergence of this effect provides an on-line analog of the long-term memory advantage for figures over grounds which Rubin (1915/1958) reported. The present on-line advantage was found when figures were defined by relative contrast and size, or by symmetry, and could not be explained solely by the automatic drawing of attention toward the location of the figural region. However, deliberate attention to one region of an otherwise ambiguous figure–ground display did produce the advantage. We propose that one-sided assignment of dividing edges may be obligatory in vision.     

Measuring How We Preach What We Practice: Psychoeducational Change in Depressed Inpatients

This study investigated the relationship between acquisition of psychoeducational principles and symptomatic improvement in depressed in-patients. One hundred and twenty-three inpatients hospitalized on a Cognitive Therapy Unit were administered the Test of Cognitive Behavioral Principles (TCBP) and the Beck Depression Inventory at admission and discharge. It was predicted that the TCBP scores would be higher at discharge than at pre-testing at admission. Further, it was hypothesized that the higher TCBP scores at post-test would be significantly correlated with lower Beck Depression Inventory scores at post-test. The results revealed that inpatients' TCBP scores improved over the course of treatment supporting the first hypothesis. However, the data did not support the second hypothesis as there was not a significant relationship between the TCBP scores and the BDI scores at discharge. The results are discussed in terms of clinical, theoretical, and methodological implications.     

THE VISUAL SYSTEM'S MEASUREMENT OF INVARIANTS NEED NOT ITSELF BE INVARIANT

Abstract— When two shapes that differ in orientation or size have to be compared or objects have to be recognized from different viewpoints, the response time and error rate art systematically affected by the size of the geometric difference. In this report, we argue that these effects are not necessarily solid evidence for the use of mental transformations and against the use of invariants by the visual system. We report an experiment in which observers were asked to give affine-invariant coordinates of a point located in an affine frame defined by three other points. The angle subtended by the coordinate axes and the ratio of the lengths of their unit vectors systematically affected the measurement errors. This finding demonstrates that the visual system's measurement of invariants need not itself be invariant.
