The importance of ‘mass’ in line drawings of faces

Previous research (Davies, Ellis and Shepherd, 1978; Rhodes, Brennan and Carey, 1987) has shown that accurate line drawings of familiar faces are identified rather poorly. However, artists can produce lifelike portraits with pen and ink, and Pearson and Robinson (1985) described an automatic method for producing computer-drawn sketches (‘cartoons’) of faces which appear very similar to those produced by a human artist. In this paper we show that subjects can identify famous faces depicted in such computer-drawn ‘cartoons’ almost as well as full grey-scale images. The cartoon algorithm comprises two components. One component draws lines at the locations of intensity changes corresponding to luminance valleys and edges (the ‘valledge’ detector). The other component applies a ‘threshold’ to the original intensity distribution, and replaces any area darker than threshold with black. Thus the full cartoon contains both ‘line’ and ‘mass’. Neither the valledges nor the threshold components alone were as well identified as full cartoons containing both components. The results suggest that the addition of the threshold component adds significantly to the identifiability of line drawings of faces.     

Confidentiality Limits With Clients Who Have HIV: A Review of Ethical and Legal Guidelines and Professional Policies

The publication of the first counseling articles addressing confidentiality limits of clients who have HIV (human immunodeficiency virus) and continue to be sexually active with an uninformed partner occurred 4 years ago. Since that time, dialogue about whether a helping professional may ethically and legally breach confidentiality has not resolved the dilemma but instead has created more questions and controversy for counselors. In this article the authors highlight the barrage of ethical issues regarding HIV and Acquired Immune Deficiency Syndrome (AlDS), review ethical and legal guidelines pertaining to HIV and AIDS and confidentiality, summarize HIV and AIDS confidentiality policies of the major helping professional organizations, articulate questions that contribute to the confidentiality dilemmas, and challenge the American Counseling Association (ACA), formerly the American Association for Counseling and Development (AACD), to develop specific guidelines for counselors.     

Recency and lexical preferences in Spanish

One experiment provided evidence in support of Gibson, Pearlmutter, Canseco-Gonzalez, and Hickok's (1996) claim that a recency preference applies to Spanish relative clause attachments, contrary to the claim made by Cuetos and Mitchell (1988). Spanish speakers read stimuli involving either two or three potential attachment sites in which the same lexical content of the two-site conditions appeared in a different structural configuration in the three-site conditions. High attachment was easier than low attachment when only two sites were present, but low attachment was preferred over high attachment, which was in turn preferred over middle attachment, when three sites were present. The experiment replicated earlier results and showed that (1) attachment preferences are determined in part by a preference to attach recently/low, and (2) lexical biases are insufficient to explain attachment preferences.     

Priming of new associations in reading time: What is learned?

The priming of new associations has been a controversial topic, with some studies finding significant effects but others failing to replicate these results. Three studies investigated the priming of new associations in a reading time task, presenting lists of word pairs that were read aloud as quickly as possible. In Experiment 1, significant priming of new associations was found after two study presentations, replicating similar results by Moscovitch, Winocur, and MacLachan (1986). In Experiment 2, reading time was facilitated for intact pairs when word positions remained constant relative to when word positions were reversed. This suggested that the associative priming effect was related to specific lower level features of the word pairs rather than to abstract associations. In Experiment 3, the insertion of the wordand between test words eliminated the pairing-specific effect, placing the locus of new association priming at the transition between words within pairs. These findings demonstrate that the knowledge that supports priming of new associations in the reading time task involves perceptual or articulatory information about the transitions between words rather than abstract associative knowledge.     

Episodic knowledge and implicit learning

Despite nearly 20 years of controversy, researchers are still divided over the contributions of abstract and episodic knowledge to performance on implicit learning tasks, and whether these types of knowledge exert their effects unintentionally or unconsciously. The present paper reviews the evidence taken to support the episodic account of implicit learning. Although substantial evidence suggests that episodic knowledge influences performance on implicit learning tasks, at present there are no techniques for testing whether these influences occur outside of awareness. It is argued that future research should investigate whether the retrieval of episodic knowledge in implicit learning tasks is insensitive to intentional control, rather than focus on the issue of awareness. Preliminary evidence suggesting that episodic knowledge can exert a nonintentional influence on task performance is reviewed, followed by a discussion of the status of consciousness as an explanatory construct in psychology.     

Subgrouping with psychiatric inpatients in group psychotherapy: linking dependency and counterdependency

Abstract A model of inpatient group psychotherapy that focuses on two frequently observed patient subgroups reflecting contrasting attitudes toward authority is presented. The counterdependent subgroup overly values autonomy, opposes unit restrictions, and rejects treatment. The dependent subgroup tends to accept the unit's treatment and structure but is overly passive. In this model these attitudes are addressed in order to help patients adapt to the unit and to facilitate discharge. The author describes a three-stage group designed to help patients achieve these goals.     

The habitual consumer

Consumers sometimes act like creatures of habit, automatically repeating past behavior with little regard to current goals and valued outcomes. To explain this phenomenon, we show that habits are a specific form of automaticity in which responses are directly cued by the contexts (e.g., locations, preceding actions) that consistently covaried with past performance. Habits are prepotent responses that are quick to activate in memory over alternatives and that have a slow-to-modify memory trace. In daily life, the tendency to act on habits is compounded by everyday demands, including time pressures, distraction, and self-control depletion. However, habits are not immune to deliberative processes. Habits are learned largely as people pursue goals in daily life, and habits are broken through the strategic deployment of effortful self-control. Also, habits influence the post hoc inferences that people make about their behavior.     

The obligatory effects of memory on eye movements

Previous work has shown that eye movement behaviour is affected by previous experience, such that alterations in viewing patterns can be observed to previously viewed compared to novel displays. The current work addresses the extent to which such effects of memory on eye movement behaviour are obligatory; that is, we examined whether prior experience could alter subsequent eye movement behaviour under a variety of testing conditions, for stimuli that varied on the nature of the prior exposure. While task demands influenced whether viewing was predominantly directed to the novel versus familiar faces, viewing of the familiar faces was distinguished from viewing of the novel faces, regardless of whether the task required incidental encoding or intentional retrieval. Changes in scanning of previously viewed over novel faces emerged early in viewing; in particular, viewing duration of the first fixation to the familiar faces was often significantly different from the duration of the first fixation directed to the novel faces, regardless of whether prior exposure was solely in the context of the experiment or due to real-world exposure. These findings suggest that representations maintained in memory may be retrieved and compared with presented information obligatorily.     

The use of background and ability profiles to predict college student outcomes

To determine whether profiles of predictor variables provide incremental prediction of college student outcomes, the authors 1st applied an empirical clustering method to profiles based on the scores of 2,771 entering college students on a battery of biographical data and situational judgment measures, along with SAT and American College Test scores and high school grade point average, which resulted in 5 student groups. Performance of the students in these clusters was meaningfully different on a set of external variables, including college grade point average, self-rated performance, class absenteeism, organizational citizenship behavior, intent to quit their university, and satisfaction with college. The 14 variables in the profile were all significantly correlated with 1 or more of the outcome measures; however, nonlinear prediction of these outcomes on the basis of cluster membership did not add incrementally to a linear-regression-based combination of these 14 variables as predictors.     

Better, Stronger, Faster: Self-Serving Judgment, Affect Regulation, and the Optimal Vigilance Hypothesis

ABSTRACT— Self-serving judgments, in which the self is viewed more favorably than other people, are ubiquitous. Their dynamic variation within individuals may be explained in terms of the regulation of affect. Self-serving judgments produce positive emotions, and threat increases self-serving judgments (a compensatory pattern that restores affect to a set point or baseline). Perceived mutability is a key moderator of these judgments; low mutability (i.e., the circumstance is closed to modification) triggers a cognitive response aimed at affect regulation, whereas high mutability (i.e., the circumstance is open to further modification) activates direct behavioral remediation. Threats often require immediate response, whereas positive events do not. Because of this brief temporal window, an active mechanism is needed to restore negative (but not positive) affective shifts back to a set point. Without this active reset, an earlier threat would make the individual less vigilant toward a new threat. Thus, when people are sad, they aim to return their mood to baseline, often via self-serving judgments. We argue that asymmetric homeostasis enables optimal vigilance, which establishes a coherent theoretical account of the role of self-serving judgments in affect regulation.
