Searching night and day: a dissociation of effects of circadian phase and time awake on visual selective attention and vigilance

How does sleepiness affect selective attention? We studied the effect of circadian phase and time awake on visual search. The generalized-cognitive-slowing hypothesis predicts that search rate will be slower, feature guidance less effective, and response time (RT) lengthened when observers are sleepy. Observers performed spatial-configuration (finding a 5 among 2s) and conjunction (finding red vertical among red horizontal and green vertical) search tasks during 38 hr of wakefulness under constant conditions. Adverse circadian phases and elapsed time awake did lead to increased RT (corrected for errors). However, contrary to the hypothesis, search rates (indexed by RT x Set Size slopes) were constant across the protocol. This was true for conjunction as well as for spatial-configuration search, indicating that feature guidance was also insensitive to sleepiness. The locus of sleepiness effects on search is probably downstream from the bottleneck of attentional selection. Observers did trade accuracy for speed when sleepy. This implicates decision-stage impairments.     

Assessing the winning teams program of interactive satellite-based training

This research assessed an interactive satellite-based training program integrating interactive audiovisual experiences with face-to-face interactions. Key elements were content created by experts, high-quality video segments, satellite-based interaction, off-line interactions among teams of parents and caregivers, workshops, and team building exercises. For pragmatic reasons, it was necessary to develop brief assessment instruments concurrently with training. A large set of survey items were created from draft materials and reduced empirically through piloting to those with the best psychometric properties. To avoid the appearance of traditional testing, knowledge was assessed with Likert items. Surveys measured participant satisfaction, knowledge, attitudes, and the application and articulation of concepts. Participant satisfaction was high. Participants increased positive attitudes and learned appropriate vocabulary. Training was more effective than no training or watching videotapes. The program appears to represent a viable model of training that could successfully be applied to Internet technologies.     

Guided Search 2.0 A revised model of visual search

An important component of routine visual behavior is the ability to find one item in a visual world filled with other, distracting items. This ability to performvisual search has been the subject of a large body of research in the past 15 years. This paper reviews the visual search literature and presents a model of human search behavior. Built upon the work of Neisser, Treisman, Julesz, and others, the model distinguishes between a preattentive, massively parallel stage that processes information about basic visual features (color, motion, various depth cues, etc.) across large portions of the visual field and a subsequent limited-capacity stage that performs other, more complex operations (e.g., face recognition, reading, object identification) over a limited portion of the visual field. The spatial deployment of the limited-capacity process is under attentional control. The heart of the guided search model is the idea that attentional deployment of limited resources isguided by the output of the earlier parallel processes. Guided Search 2.0 (GS2) is a revision of the model in which virtually all aspects of the model have been made more explicit and/or revised in light of new data. The paper is organized into four parts: Part 1 presents the model and the details of its computer simulation. Part 2 reviews the visual search literature on preattentive processing of basic features and shows how the GS2 simulation reproduces those results. Part 3 reviews the literature on the attentional deployment of limited-capacity processes in conjunction and serial searches and shows how the simulation handles those conditions. Finally, Part 4 deals with shortcomings of the model and unresolved issues.     

Traditionality of choice and sex-role identification as moderators of the congruence of occupational choice in college women

This study examined the relationship of traditionality of occupational preferences and sex-role orientation to personality-occupational environment congruence in college women. Three-letter Holland personality codes were obtained for each of 184 college women based on same-sex normative scores from the Strong-Campbell Interest Inventory and on scores from the ACT Unisex Interest Inventory (UNIACT). Subjects' occupational preferences were classified as traditional, moderately traditional, or nontraditional based on the percentages of women in the occupation. Scores on the Bern Sex Role Inventory were used to classify subjects into one of four sex-role categories. Results indicated a strong association between congruence and traditionality of choice; women whose choices were in nontraditional career fields were significantly more likely to be making choices congruent with their personality type than were women choosing traditional career fields. Further, while sex-role orientation was not significantly related to either congruence or traditionality, masculine-typed women were most likely to make nontraditional and congruent career choices, while the majority of feminine-typed, androgynous, and undifferentiated women stated preferences for traditional career fields. Implications for the applicability of Holland's congruence postulate to women's vocational behavior are discussed.     

The Felt Figure Replacement Technique as a personality assessment device: validity reconsidered

Conclusions from an earlier study testing the validity of the Felt Figure Replacement Technique (FFRT) were questioned and three new measures of FFRT performance were developed. The reliability of these three measures, and the conventional measure of distance error, was checked using a sample of 54 female and 49 male undergraduates at Oregon State University. These subjects also completed an established personality inventory. Three of the four FFRT measures tested proved to be reliable, and it was found that models combining the three reliable FFRT measures could yield successful predictions on the personality dimensions for females but not for males; although males and females perform similarly on the FFRT. Both groups made the same kinds of errors relative to the standard placement. Also, males and females differ on only one of the three reliable FFRT measures. It was concluded that the FFRT may yet prove a valuable assessment approach, and the implications of these conclusions for personality assessment were discussed.     

Professional Development in Social Justice: Analysis of American Counseling Association Conference Programming

This study was designed as a content analysis of 2012–2017 American Counseling Association conference sessions to examine how social justice was presented. Four findings emerged from the qualitative content analysis: (a) rates of social justice sessions varied over time; (b) there were more multicultural sessions than social justice sessions; (c) populations that were addressed least often and most often were identified; and (d) there was a decline in the number of social justice content sessions. Implications are presented.     

Searching while loaded: Visual working memory does not interfere with hybrid search efficiency but hybrid search uses working memory capacity

In “hybrid search” tasks, such as finding items on a grocery list, one must search the scene for targets while also searching the list in memory. How is the representation of a visual item compared with the representations of items in the memory set? Predominant theories would propose a role for visual working memory (VWM) either as the site of the comparison or as a conduit between visual and memory systems. In seven experiments, we loaded VWM in different ways and found little or no effect on hybrid search performance. However, the presence of a hybrid search task did reduce the measured capacity of VWM by a constant amount regardless of the size of the memory or visual sets. These data are broadly consistent with an account in which VWM must dedicate a fixed amount of its capacity to passing visual representations to long-term memory for comparison to the items in the memory set. The data cast doubt on models in which the search template resides in VWM or where memory set item representations are moved from LTM through VWM to earlier areas for comparison to visual items.     

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.     

Rational Emotive Behavior Therapy Successes and Failures: Eight Personal Perspectives

Eight experts in Rational Emotive Behavior Therapy (REBT) provided personal examples of their own successes and failures in applying REBT to themselves. The experts actively talked to themselves both rationally and irrationally. Understandably, there were far more shoulds, oughts, musts, and have to's in the narratives in which the experts described when they failed to use REBT than when they succeeded in using REBT. Rational self‐talk was more prevalent in the examples of how REBT was successfully used by the experts.     

ANALYZING THE INFLUENCE OF TIC‐RELATED TALK ON VOCAL AND MOTOR TICS IN CHILDREN WITH TOURETTE'S SYNDROME

This study examined the effect of tic‐related talk on the vocal and motor tics of 2 boys with Tourette's syndrome. Using ABAB withdrawal designs, the boys were alternately exposed to conditions with and without talk of their tics. For both boys, vocal tics markedly increased when talk pertained to tics and decreased when talk did not pertain to tics, but motor tic covariance was less consistent.
