Evaluating a treatment without extinction for elopement maintained by access to stereotypy

Elopement is a common and potentially dangerous form of problem behavior. Results of a functional analysis found that the elopement of a child with autism was maintained by access to stereotypy in the form of door play. We implemented functional communication training and contingency-based delays dependent on the absence of elopement and increased the amount of time the participant waited prior to engaging in stereotypy. We also conducted treatment-extension probes, with the participant waiting up to 10 min without elopement.     

Using ecphoric confidence ratings to discriminate seen from unseen faces: The effects of retention interval and distinctiveness

Theories of confidence processing for recognition judgments suggest that confidence indexes the degree of match between a presented stimulus and an image in memory (ecphoric similarity). Recent research has demonstrated that having participants rate their confidence that a face had been previously seen provides an equivalent or a better index of the stimulus's status than does eliciting a simple binary response (Sauer, Brewer, & Weber, Journal of Experimental Psychology: General 137: 528-547, 2008). Using a face recognition paradigm, we manipulated retention interval and stimulus distinctiveness to directly test the suggestion that confidence indexes ecphoric similarity and to probe the boundary conditions for using confidence ratings to discriminate seen from unseen faces. Consistent with the proposed ecphoric basis for confidence ratings, mean confidence was higher for previously seen than for unseen faces, and conditions conducive to the formation of strong memories improved confidence-based discrimination. In all conditions, after the application of a classification algorithm, confidence ratings provided a more sensitive index of face status (i.e., seen or unseen) than did binary responses.     

Attention Bias for Threatening Information in Children Following a Distressing Medical Procedure

Attention bias is common in adults with post‐traumatic stress disorder (PTSD) but is less studied in children. Children (n = 22) who experienced a potentially distressing procedure in an outpatient clinic (removal of K‐wires from orthopaedic fractures) and a group of medically unwell children (illness group; n = 27) were compared with healthy controls (n = 32). Children's baseline level of PTS symptoms were indexed prior to the medical procedure, and again at 1‐week follow‐up. Immediately after the K‐wire removal, children completed a dot probe task using two categories of target words (medical threatening and emotionally threatening). While K‐wire children showed an overall bias away from negative words relative to healthy controls, the illness group did not significantly differ from healthy controls. Attention bias in K‐wire and illness groups was unrelated to later PTS symptoms.     

Level of performance accuracy for core Halstead-Reitan measures by pooling normal controls from published studies: comparison with existing norms in a clinical sample

The Halstead-Reitan Neuropsychological Test Battery offers a multifaceted, empirically supported interpretive framework for neuropsychological assessment founded upon raw scores referenced to a brain-damaged sample. Complementary approaches have used T scores from normal samples often composed of community volunteers or medical patients, augmented by regression. By pooling normal controls of all types from published studies, a sample large enough for stratification of core Halstead-Reitan measures by age and education was obtained (206 studies, N1 = 17,980). Comparisons based on T scores with two published normative systems in an outpatient sample produced a continuum: liberal norms for medical patients, intermediate pooled values from many types of subjects, and stringent norms for community volunteers. Features recommending clinical application of pooled norms include enhanced accuracy in clinical situations precluding a full battery, few empty cells or inversions for nonelderly subjects, and a screening application based upon a very large Trail Making Test sample (Trails B: n > 14,000).     

Understanding the dynamics of correct and error responses in free recall: Evidence from externalized free recall

The dynamics of correct and error responses in a variant of delayed free recall were examined in the present study. In the externalized free recall paradigm, participants were presented with lists of words and were instructed to subsequently recall not only the words that they could remember from the most recently presented list, but also any other words that came to mind during the recall period. Externalized free recall is useful for elucidating both sampling and postretrieval editing processes, thereby yielding more accurate estimates of the total number of error responses, which are typically sampled and subsequently edited during free recall. The results indicated that the participants generally sampled correct items early in the recall period and then transitioned to sampling more erroneous responses. Furthermore, the participants generally terminated their search after sampling too many errors. An examination of editing processes suggested that the participants were quite good at identifying errors, but this varied systematically on the basis of a number of factors. The results from the present study are framed in terms of generate-edit models of free recall.     

Variation in working memory capacity and intrusions: Differences in generation or editing?

The current study explored the reason for the relation between individual differences in working memory capacity (WMC) and intrusions in free recall. High and low WMC individuals were tested in standard delayed free recall and externalised free recall in which participants recalled everything that came to mind. Additionally, in externalised free recall participants were instructed to press a key for each item that they knew was an intrusion. In delayed free recall, low WMC individuals recalled fewer correct items and more previous list and extralist intrusions than high WMC individuals. In externalised free recall, differences only arose in previous list intrusions. Furthermore, in externalised free recall it was found that low WMC were less likely to identify both types of intrusions than high WMC individuals. It is argued that the reason low WMC individuals recall more intrusions than high WMC in free recall is due to differences in both generation and editing abilities.     

Individual differences in everyday retrospective memory failures

The present study examined individual differences in everyday retrospective memory failures. Undergraduate students completed various cognitive ability measures in the laboratory and recorded everyday retrospective memory failures in a diary over the course of a week. The majority of memory failures were forgetting information pertaining to exams and homework, forgetting names, and forgetting login and ID information. Using latent variable techniques the results also suggested that individual differences in working memory capacity and retrospective memory were related to some but not all everyday memory failures. Furthermore, everyday memory failures predicted SAT scores and partially accounted for the relation between cognitive abilities and SAT scores. These results provide important evidence for individual differences in everyday retrospective memory failures as well as important evidence for the ecological validity of laboratory measures of working memory capacity and retrospective memory.     

The Effects of Music and a Coxswain on Attentional Focus,Perceived Exertion,Motivation, and Performance During a 1,000 m Ergometer Rowing Sprint

Music has often been portrayed as a dissociative (i.e., distracting) mechanism. This study demonstrates that music may not be unifunctional in regards to attentional focus; that is, external concentration on music can coexist with task-relevant thoughts. Female intercollegiate rowers (N = 26) performed four 1,000 m sprints on a rowing ergometer at maximal effort under music, coxswain, combined music and coxswain, and control conditions. Findings indicate that during the 1,000 m rowing sprint, both external and task-relevant dimensions of attentional focus can exist simultaneously. This implies a new consideration of music as either dissociative or associative based on task-related factors.     

When Sport psychology consultants and graduate students are impaired: Ethical and legal issues in training and supervision

Abstract

Impaired sport psychology consultants, that is, professionals and graduate students whose behavior, inadequate training, personal situations, or psychopathology are having a negative influence on the delivery of services, have the potential to do harm to athlete-clients, damage their own professional standing, and bring disrepute to the field. The applied sport psychology literature is replete with guidelines and suggestions for referring athletes for counseling or psychotherapy when appropriate (e.g., Heyman & Andersen, 1998), but the ethical, legal, and procedural problems associated with sport psychology consultants whose training or mental conditions suggest the need for remediation, rehabilitation, or psychotherapy, and possible removal from seeing clients, has not been addressed. We describe a variety of situations where student and professional functioning might be impaired, discuss the possible ramifications (legal, ethical) of impairment, and provide suggestions for ways to proceed when sport psychology consultants are in psychological difficulty.
