Jump performance and augmented feedback: Immediate benefits and long-term training effects

Drop jumps and their adaptations to training have been extensively investigated. However, the influence of augmented feedback (aF) on stretch-shortening cycle (SSC) was not scrutinized so far despite the well-known positive effects of aF on motor performance and motor learning. The aim of the present study was therefore to investigate the effects of aF by evaluating immediate within-session effects and long-term adaptations. 34 participants were assigned to three groups that trained drop jumps with different relative frequencies of aF about their jump height: 100%, 50%, or 0%. A significant within-session effect of aF on jump height was observed before and also after the training period (pre: +4.6%; post: +2.6%). In the long-term (comparing pre- to post-measurement), the 100% group showed the greatest increase in jump height (+14%), followed by the 50% (+10%) and the 0% group (+6%). The importance of aF on drop jumps is therefore twofold: (i) to immediately increase jump performance and (ii) to improve long-term training efficacy. In contrast to the proposition of the guidance hypothesis, high frequency of aF seems to be beneficial when maximizing SSC-performance. As jump height cannot be quantified without objective technical measures it is recommended to include them into daily training.     

False autonomic feedback: Effects of attention to feedback on ratings of erotic stimuli

This study examines the roles played by sound track type, attention to sound track, and meaning of sound track in mediating the effects of false autonomic feedback on attractiveness ratings of erotic stimuli. Male subjects were instructed either to ignore or to pay attention to a pulsed or continuous sound track that was described either as heart-rate feedback or as a neutral auditory stimulus while slides of nude females were shown. Slides associated with a change in either the pulsed sound track or the continuous-tone sound track (increase slides) were subsequently rated as significantly more attractive than those associated with steady sound (stable slides). This effect was contingent on the meaning given to the auditory stimuli, with subjects in the heart-rate condition showing a stronger tendency to rate increase slides more positively than stable slides, by comparison with subjects in the neutral sounds condition. Within the heart-rate condition, subjects told to pay attention to the feedback showed greater rating differences between these two types of slide than those told to ignore it. This pattern of findings contrasts with those of an earlier experiment (Parkinson & Manstead, 1981), where differential unpleasantness ratings of slides of skin diseases depended on the attention paid to the sound track but not on its meaning. It is concluded that the effects of false autonomic feedback are contingent upon the kind of emotional stimuli that are presented.This article is based on research supported by the Economic and Social Research Council (UK). We gratefully acknowledge the assistance of Andrew Gregory, who was responsible for the computer program used in generating the sound track, and we would like to thank the anonymous reviewers for their comments on a previous version of this paper.     

Foveal metacontrast: I. Criterion content and practice effects

Strong metacontrast was found during experiments involving foveal presentation of stimuli. Follow-up experiments indicate that foveal metacontrast can be accounted for in some conditions by a practice effect and/or a criterion-content change, which occurs with practice and involves a biphasic brightness response to the target. Consideration of these factors may help resolve some of the many apparent disparities in the metacontrast literature. The relevance of these factors to metacontrast theories is discussed.     

False autonomic feedback: Effects of attention to feedback on ratings of pleasant and unpleasant target stimuli

This study investigates the potential interactions among some of the key variables in Valins's (1966) false autonomic feedback paradigm. Subjects were shown mildly pleasant or mildly unpleasant slides of animals while they either paid attention to or ignored a continuous-tone soundtrack that increased in pitch in conjunction with half of the pictures. This soundtrack was described either as feedback of skin conductance level or as a neutral auditory stimulus. Slides associated with increased pitch were generally rated as more affectively potent (in either the positive or negative direction, depending on their initial affective valence). For pleasant slides, this effect was contingent on attention to the soundtrack, such that subjectsignoring the sounds showed a stronger differential rating effect regardless of the meaning ascribed to the sound. For both pleasant and unpleasant slide conditions, the only subject groups showing significant rating effects were those ignoring neutrally described sound. It is argued that this pattern of results poses severe problems for a conventional attributional analysis of the Valins effect.This article is based on research funded by the Economic and Social Research Council (UK) under its Postdoctoral Research Fellowship Scheme.

Using client feedback in training of future counseling psychologists: An evidence-based and social justice practice

Training in counseling psychology has evolved to emphasize both evidence-based practice (EBP) and social justice, though these two dimensions have often seemed disconnected, or even at odds in the practice of psychotherapy. The Partners for Change Outcome Management System (PCOMS), an EBP that monitors treatment outcomes and the therapeutic alliance across treatment (often called “client feedback”), may offer a means to connect evidence-based and socially just practices. The purpose of this article was to outline how the use of PCOMS in psychotherapy and supervision can serve as a useful training tool that is a form of EBP and also promotes a socially just paradigm in psychotherapy. We also offer an implementation example from a counseling psychology doctoral program to demonstrate how PCOMS can be used with clients in psychotherapy and included within the supervisory process.     

Understanding the motivational effects of procedural and informational justice in feedback processes

Building upon traditional feedback models, this study examined the role of fair treatment in feedback contexts. Structural equation modelling using data from 236 undergraduate students highlighted perceived accuracy as a mediator in the credibility‐motivation relationship as well as a relationship between accuracy and perceptions of procedural and informational justice. In addition, the results showed that the motivating effects of feedback accuracy partially occurred through procedural justice perceptions. Tests of an alternative model also demonstrated the interactive effects of credibility and accuracy on justice perceptions. Overall, this study provides insight into the role of fairness in appraisal processes, as well as how fairness might enhance recipients' reactions to appraisal and, subsequently, the effectiveness of appraisal systems.     

Biofeedback training of relaxation: The effects of false feedback and the influence of suggestibility

The effect of contingent and non-contingent (false) biofeedback upon heart rate (HR) and subjective reports of relaxation was investigated, and the role played by suggestibility as an individual difference was examined. There were four experimental groups. One received true contingent HR biofeedback and another received no feedback at all. There were also two non-contingent groups. One received false information suggesting that HR was going down and one group received information suggesting that HR was going up. Ss' level of suggestibility was also assessed. Comparisons between the feedback conditions and the no feedback group confirmed the efficacy of biofeedback in relation to the reduction of HR. However, non-contingent feedback was found to be as effective as contingent feedback in HR reduction. Suggestibility as an individual difference was not found to be related to HR reduction but did play a complex role in the subjective report of relaxation. Results are discussed emphasising the non-specific component of the biofeedback paradigm and thus questioning the operant-conditioning model.     

Children's nighttime fears: parent-child ratings of frequency, content, origins, coping behaviors and severity

The present study investigated nighttime fears in normal school children aged 4 to 12 yr (N=176). Children and their parents were interviewed about the frequency, content, origins, coping behaviors and severity of children's nighttime fears. Results showed that 73.3% of the children reported nighttime fears, indicating that these fears are quite prevalent. Inspection of the developmental course of nighttime fears revealed that these fears are common among 4- to 6-year-olds, become even more frequent in 7- to 9-year-olds and then remain relatively stable in 10- to 12-year-olds. Inspection of the origins of nighttime fears revealed that most of the children (i.e., almost 80%) attributed their fear to negative information; conditioning and modeling were endorsed less frequently (25.6% and 13.2%, respectively). A substantial percentage of the children (24.0%) indicated that learning experiences had not played a role in the acquisition of their nighttime fears. Children reported a variety of coping strategies in order to deal with their nighttime fears and generally rated these strategies as helpful in reducing anxiety. Furthermore, children's nighttime fears were associated with moderate levels of anxiety. Moreover, in about 10% of the children, nighttime fears were related to one or more DSM-III-R anxiety disorders. Finally, parental reports of children's nighttime fears substantially deviated from children's reports. Most importantly, parents provided a marked underestimation of the frequency of nighttime fears, at least as reported by their children.     

Retaking ability tests in a selection setting: implications for practice effects,training performance,and turnover

This field study investigated the effect of retaking identical selection tests on subsequent test scores of 4,726 candidates for law enforcement positions. For both cognitive ability and oral communication ability selection tests, candidates produced significant score increases between the 1st and 2nd and the 2nd and 3rd test administrations. Furthermore, the repeat testing relationships with posthire training performance and turnover were examined in a sample of 1,515 candidates eventually selected into the organization. As predicted from persistence and continuance commitment rationales, the number of tests necessary to gain entry into the organization was positively associated with training performance and negatively associated with turnover probability.     

Understanding the latent structure of job performance ratings

This study quantified the effects of 5 factors postulated to influence performance ratings: the ratee's general level of performance, the ratee's performance on a specific dimension, the rater's idiosyncratic rating tendencies, the rater's organizational perspective, and random measurement error. Two large data sets, consisting of managers (n = 2,350 and n = 2,142) who received developmental ratings on 3 performance dimensions from 7 raters (2 bosses, 2 peers, 2 subordinates, and self) were used. Results indicated that idiosyncratic rater effects (62% and 53%) accounted for over half of the rating variance in both data sets. The combined effects of general and dimensional ratee performance (21% and 25%) were less than half the size of the idiosyncratic rater effects. Small perspective-related effects were found in boss and subordinate ratings but not in peer ratings. Average random error effects in the 2 data sets were 11% and 18%.     

Presentation modality and indirect performance information: effects on ratings,reactions, and memory

The authors investigated whether raters integrate indirect (second-hand) information from an employee's co-worker with their direct observations when completing performance evaluations. Performance levels of direct and indirect information and presentation modality (auditory vs. textual) were manipulated (N = 220). Results showed that indirect information was perceived to be of highest utility when the performance levels of the direct and indirect information were consistent. Confidence in performance ratings was lowest when the indirect source delivered negative performance feedback that was contrary to the rater's own positive observations. Indirect information was only reflected in the performance ratings when direct observations were positive. There was a significant 3-way interaction between performance level of the direct information, performance level of the indirect information, and presentation modality on memory for performance incidents.     

Rater training revisited: An updated meta‐analytic review of frame‐of‐reference training

The present study updates Woehr and Huffcutt's (1994) rater training meta‐analysis and demonstrates that frame‐of‐reference (FOR) training is an effective method of improving rating accuracy. The current meta‐analysis includes over four times as many studies as included in the Woehr and Huffcutt meta‐analysis and also provides a snapshot of current rater training studies. The present meta‐analysis also extends the previous meta‐analysis by showing that not all operationalizations of accuracy are equally improved by FOR training; Borman's differential accuracy appears to be the most improved by FOR training, along with behavioural accuracy, which provides a snapshot into the cognitive processes of the raters. We also investigate the extent to which FOR training protocols differ, the implications of protocol differences, and if the criteria of interest to FOR researchers have changed over time.     

Rater information acquisition processes: Tracing the effects of prior knowledge, performance level, search constraint, and memory demand

Research on performance ratings has tended to neglect factors affecting raters' acquisition of ratee performance information. The present research examined the dynamic effects of this rater information acquisition process. Study 1 examined the effects of prior ratee knowledge (familiarity) and ratee performance level on subsequent acquisition of ratee performance information under varying levels of constraint. After exposure to prior ratee information, raters acquired additional information concerning a set of ratees using a computer controlled information board procedure. The results indicated significant effects on the amount of search for prior knowledge, search constraint, and the interaction between prior knowledge and performance level. Study 2 extended the research by including a memory component (time delay) between the exposure to prior information and subsequent search. Results were congruent with Study 1. They indicated significant main effects on the amount of search for prior knowledge, ratee performance level, search constraint, and on the interaction between prior knowledge and performance level. In addition, the results indicated a significant interaction between memory demand and prior knowledge. Implications of these results, limitations, and extensions of this research approach are discussed.     

Effects of false heart rate feedback and task instructions on information search,attributions, and stimulus ratings

Summary Predictions derived from an information seeking, attribution model of false autonomic feedback were tested in an experiment using a 3 × 3 design. Male students (n = 61) viewed aversive slides accompanied by either increasing, constant, or no heart sounds. They were instructed either to attend to slides and sounds labelled extraneous, or to slides and sounds labelled as their own heart beats, or to try to explain their fictitious heart beats through slide features (attribution condition). Increase and constant feedback instigated equally intense information search (measured through self-determined viewing time and heart-rate deceleration) but increased feedback did not direct the search (measured through viewing time distribution and recall) more towards negative or less towards neutral features than did constant feedback. Increased feedback enhanced rated slide unpleasantness in the attention and attribution conditions whereas constant feedback decreased unpleasantness in the attribution condition only. Correlations were consistent with the hypothesis that attributions of fictitious autonomic reactions, but not information search and actual heart rate, mediate feedback effects on stimulus valences.The author would like to thank Paul Wagemann, who ran part of the subjects, Alfred Holl, who helped to cope with equipment problems, and Günter Eisenhut, who assisted in data reduction and analysis.     

Understanding the effects of task-specific practice in the brain: Insights from individual-differences analyses

We used functional magnetic resonance imaging to study practice effects in different mental imagery tasks. The study was designed to address three general questions: First, are the results of standard group-based analyses the same as those of a regression method in which brain activation changes over individual participants are used to predict task performance changes? With respect to the effects of practice, the answer was clear: Group-based analyses produced different results from regression-based individual-differences analyses. Second, are all brain areas that predict practice effects consistently activated across participants? Again, the answer was clear: Most areas that predicted the effects of practice on performance were not activated consistently over participants. Finally, does practice affect different areas in different ways for different people in different tasks? The answer was again clear: The areas that predicted changes in performance with practice varied for the different tasks, but this was more dramatically and clearly revealed by the individual-differences analyses. In short, individual-differences analyses provided insights into the relation between changes in brain activation and changes in accompanying performance, and these insights were not provided by standard group-based analyses.     

Understanding,respecting and integrating difference in therapeutic practice

The purpose of this paper is to promote thought and discussion around how and why we treat patients in chosen ways. In the present climate practitioners are required to treat patients following NICE guidelines in which cognitive behavioural therapy (CBT) is the treatment of choice in the majority of diagnoses. This paper raises concerns that this may lead to an homogenization of treatment, loss of invaluable skills and understanding from other treatment approaches, and loss to the patient who may be best cared for by a combination of treatments and approaches, most notably patients presenting with complex pathology. This paper aims to present this as a general principle, and by way of example, will focus on coupling two specific treatment orientations, cognitive behavioural therapy with psychodynamic psychotherapy, with the specific diagnosis of obsessive compulsive disorder (OCD).

Methods: Clinical material is drawn from case studies from practice in secondary adult mental health care services within the NHS. All patients were referred to the psychological services for treatment for OCD and provided with 1:1 therapy with UKCP‐registered therapists. Details have been anonymized by describing fictitious cases re‐constructed from clinical material. A theoretical understanding is included which provides both an overview for integrating treatment for the specific example of OCD and is intended by extension to other diagnoses.

Results: Working with the commonalities of therapeutic approaches, and integrating specific skills of CBT and psychodynamic psychotherapy, appears to offer a viable mode of treatment for cases resistant to single‐orientation therapies.

Conclusions: Coupling the skills of different therapies can be effective in treating complex patients that are referred to the secondary mental health services. Conversely, restricting practice to single orientation therapies can lead to an impoverished care for patients and diminution of invaluable therapeutic skills which may become underused, undervalued and lost in the practice of mental health care within the NHS. Acknowledgement of the skills of others, valuing these and learning from each other can help to avoid the defensive reactions of practitioners, where each may defensively retreat to their corners of specialism. Respecting and sharing skills from different orientations, and acknowledging this in the NICE guidelines, is good for both mental health services and patient care and addresses the concerns raised by practitioners exemplified by Bateman (2000 Bateman, A. 2000. Integration in psychotherapy: An evolving reality in personality disorder.. British Journal of Psychotherapy, 17(2): 147–156.  [Google Scholar], p. 147) that ‘psychotherapy continues to be bedeviled by ideological schisms with practitioners apparently ignoring alternative conceptualizations and potentially superior interventions’.
