Visual–perceptual and cognitive differences between expert,intermediate, and novice snooker players

The performance of seven expert, seven intermediate, and 15 novice snooker players was compared on a range of general visual tests and sport-specific perceptual and cognitive tests in an attempt to determine the locus of the expert advantage. No significant expert-novice differences were apparent on standard optometric tests of acuity, ocular muscle balance, colour vision, and depth perception, nor on the relative frequency of unilateral and cros-lateral eye-hand dominances. Experts, however, were found to be superior in their ability to both recall and recognize rapidly-presented slides depicting normal game situations, but were no better than novices in recalling information from slides in which the balls were arranged randomly on the table. The expert group's superiority on the perceptual recall and recognition tasks was consistent with a deeper level of encoding for structured (meaningful) material. Experts were also shown, through the use of thinking-aloud and evaluation paradigms, to use a greater depth of forward planning in choosing appropriate shot options and to evaluate existing situations with greater accuracy, discriminability, and prospective planing than did novices. The cognitive advantage is shown to be a potential contributor but not a total explanation of the superior performance of the experts on the perceptual tasks. The findings of this study are consistent with existing works on expertise in board games and ‘open’ skill sports in indicating that the expert's advantage is not a general but a specific one, arising not from physical capacities but from acquired processing strategies.     

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.
