Abstract

EMG-biofeedback assisted relaxation training was used in the treatment of tension headache. Two groups of subjects were treated with either a “standard biofeedback” method, or a “biofeedback with generalization training” method. The latter included procedures which were aimed at maximizing voluntary control of frontal muscle activity in the absence of external feedback, as well as the ability to use the self-regulation skills in every-day life. The results indicated that only the “standard biofeedback” group showed evidence of increased relaxation abilities. However, these greater achievements were not accompanied by comparable superiority regarding headache decreases. These results are discussed and some hypothetical explanations are put forward.     

BIOFEEDBACK AND RATIONAL-EMOTIVE THERAPY IN THE MANAGEMENT OF MIGRAINE HEADACHE

Twenty-four migraine patients were randomly assigned to one of four conditions: (a) self-monitoring of headache activity (waiting list), (b) frontalis EMG biofeedback, (c) digit temperature biofeedback, and (d) digit temperature biofeedback plus Rational-Emotive Therapy (RET). Bidirectional control over the target physiological response was assessed through a reversal design in each session. Following at least a four-week baseline, the three biofeedback groups received 8 to 10, 30-minute sessions of bidirectional biofeedback training, scheduled twice a week. Subjects in the combined digit temperature biofeedback plus RET group received three 40-minute sessions of RET as an addition to the third, fifth, and seventh biofeedback sessions. Records of daily home practice were kept throughout treatment and three-month followup. Subjects on the waiting list monitored headaches for at least five months, corresponding to “baseline”, “treatment”, and three-month followup. Digit temperature biofeedback alone and in conjunction with RET did not prove to be more effective than the control conditions. All the EMG subjects reduced headache activity to two-thirds or less of the baseline level by the third month of followup. Bidirectional digit temperature performance did not improve with training, was demonstrated in only 33% of the biofeedback sessions, was not maintained over time, and was unrelated to improvement in headache activity. EMG subjects reported biofeedback performance to be an easier task and met the performance criterion on 85% of the sessions. The frequency of home practice contributed over 55% of the variance in retrospective estimates of headache improvement but was not related to changes in daily records of headache activity.     

Word recognition across orthographies: Another look at the interaction between context and degradation

Abstract

The performance of English and Spanish subjects was examined in two experiments using a lexical decision task in which the effects of semantic priming and stimulus degradation were systematically varied. The Orthographic Depth Hypothesis predicts that priming and degradation will interact in the orthographically “deep” language (English) but not in the “shallow” one (Spanish). In the first experiment, the two factors were found to interact in a similar way in both English and Spanish groups. In the second experiment, in which only Spanish subjects participated, the interaction was again present but only in those subjects who showed an overall facilitation effect on primed words. The results are consistent with the use of the so-called “direct” route in Spanish and are at variance with other previous findings which have suggested that reading in shallow orthographies occurs via the “indirect” phonological route. There was also evidence that nonword rejection times were slower in Spanish subjects and that the performance of the two groups was affected differently by the different types of neutral baseline primes (asterisks or unrelated words). Possible interpretations of these performance variations are briefly discussed.     

Long-term follow-up of migraine treatment: do the effects remain up to six years?

Fifty migraine subjects (constituting 79% of the originally treated sample) participated in a follow-up study to 6 yr after the end of treatment. Subjects had been treated with different forms of biofeedback methods (skin temperature, BVP of the temporal artery) and applied relaxation training. The assessment included 4 weeks of continuous self-monitoring of headache activity and medication usage, as well as a retrospective self-rating scale. The main results indicated that, on a group basis, headache reductions achieved at the end of treatment persisted for up to 6 yr, and were indeed enhanced during the follow-up period.     

Breakdown in communication: On finding the child in the analysis of an adult

SUMMARY

In this paper a patient is described in whom communication with parts of herself and with her objects, internal and external, had broken down. I suggest that her way of communicating was achieved by projective identification, as described by Klein (1946) and Bion (1962). The only way she could deal with and communicate her own very “bothered” feelings was to “put them” into the analyst. In this way she “bothered” the maternal or analytic mind in such a way as to make the analyst experience feeling like a “bothered” child.

I have tried to show how the analyst holds or contains these feelings, and to show the gradual establishment in the patient of a different way of communicating with the analyst and with the more primitive parts of herself.     

Predicting sports performance from well-being: A mapping of professional athletes’, amateur athletes’ and non-athletes’ positions

IntroductionPrediction of performance and well-being are two essential keys in sports performance.ObjectiveThe study aimed to map different positions regarding the way in which individuals integrated mentally five elements of eudaimonic well-being (relatedness, autonomy, competence, mental vitality and physical vitality) for predicting the degree of performance at the beginning of a match.MethodTwenty-four non-athletes, 44 amateur athletes and 26 professional athletes indicated their prediction of performance in 32 scenarios constructed from the combination of these elements of well-being. Cluster analysis, ANOVAs, and chi-square test have been done.ResultsTwo positions on prediction of performance were found. The first cluster was called “Sometimes Performance Prediction” and the second cluster was named “Seldom Performance Prediction”. The five elements had a positive effect on the prediction of performance. The composition of both clusters was linked to the level of involvement in sport.ConclusionOffering athletes a “well-being environment” may lead to predict the sports performance.     

Age differences in proactive interference in verbal and visuospatial working memory

Abstract

In a free recall situation, subjects can predict, with some degree of accuracy, which words they will subsequently recall. This study focused on the question of why subjects often recall words to which they assign low prediction ratings. This problem was approached by comparing the properties of recall-not-predicted (RNP) and recall-predicted (RP) words which appeared in subjects' recall protocols. No differences were found between the two types of items (RNP and RP) in retrieval monitoring. The two types of items were differentiated by whether subjects could recollect the actual occurrence of the recalled items in the study list (“remember” responses) or not (“know” responses). Furthermore, the recall of RNP items, but not RP items, was improved by retrieval prompts. These results were taken to support the position that weakly encoded items may be recalled if they encounter a highly favourable retrieval environment, not anticipated by subjects during study.     

The treatment of tension headache—I. Muscular abnormality and biofeedback

The specificity and efficacy of a short EMG biofeedback treatment were assessed in a selected group of chronic tension-headache cases—those having significantly elevated levels of muscle tension. The effects of training patients to raise/maintain EMG levels were compared to those obtained from patients who were trained to lower tension levels. The results showed little evidence of increased self-control of the muscle despite successful EMG control during six bio-feedback sessions. A progressive and significant reduction in resting level was found only in the groups trained to reduce EMG levels. The treatment proved ineffectual in reducing headache. The implications of the dissociation of muscle tension and headache are discussed both with respect to current views of tension headaches and the role of biofeedback in their treatment.     

Maintaining a healthy diet: Effects of personality and self-reward versus self-punishment on commitment to and enactment of self-chosen and assigned goals

Abstract

A theory decomposing volition into four modes of central organization of executive control functions is outlined. These modes include (1) an autonomy-oriented mode (“self-regulation”) which is facilitated by challenging conditions and positive mood, (2) a self-suppressive mode oriented toward external-control (“self-control”) facilitated by negative mood and two modes associated with volitional inhibition (“state orientation”). Two experiments are reported that test predicted interactions between dispositional and situational factors in determining commitment to and actual enactment of self-chosen versus assigned activities directed at changing nutritional behavior. The results confirm the predicted disordinal interactions: The degree of commitment to and enactment of intended behavioral changes depends upon an interaction between personality (volitional styles), type of self-regulatory task (eat more healthy versus avoid unhealthy food), and instructional focus on easy versus difficult steps (Study 1) or self-reward versus self-punishment strategies (Study 2). Practical implications for designing intervention procedures according to individual personality characteristics and situational constraints are discussed.     

Using Stories in Dynamically Oriented Clinical Social Work

Abstract

This paper uses concepts from discourse analysis to understand the meaning making functions of narrative in clinical treatment and to describe the interactive processes through which these functions are achieved. “Negotiative” and “heuristic” narrative processes are described as they occur in ordinary conversation. The relevance of these concepts to clinical practice is then explored using case material.     

Conceptions of the Opposite-Sex Ideal by International Students in the Netherlands

Abstract

An exploratory cross-cultural survey was used to investigate similarities and differences in stereotypes of good and evil. Students from the United States, West Germany (Federal Republic of Germany), Singapore, Nigeria, and Argentina responded projectively to a 62-item questionnaire, completing it as they imagined an extremely “good and virtuous,” an extremely “wicked and evil,” or an extremely “weak and helpless” person would. Two factors consistently emerged: control (the impulse to influence or dominate others) and power (the impulse to accomplish objectives). Stereotypes of good, bad, and helpless were related to extreme positions on these factors, suggesting that the concepts of good and evil are richer than simply opposite poles of a single, evaluative dimension. Strong similarities in factor structures were found across the five samples, but inconsistencies also emerged. In general, control and power appear to have been common across cultures; however, the five samples operationalized them, as well as good and evil, somewhat differently.     

Order of strokes writing as a cue for retrieval in reading chinese characters

Abstract

Chinese characters are composed of a number of strokes, varying from 1 to 23. The strokes of each character have to be written in a precise order, which is codified in a number of rules, and which is learned in the process of literacy acquisition. The present study tested the hypothesis that stroke writing order has been coded in memory as an essential component of the orthographic knowledge of a character, and that this specific motor schema is used as a cue in lexical retrieval. In the first experiment reported here, fragments of Chinese characters consisting of “early” or of “late” strokes (namely strokes which are written first or last during writing) were pre-exposed to target characters to be named as fast as possible. The results indicated that “early” strokes were better retrieval cues for character names than “late” strokes. In the second experiment, subjects were requested to make same-different judgements about two characters which had in common either “early” or “late” strokes. Different characters sharing “early” strokes were more frequently erroneously judged as being identical than characters sharing “late” strokes.     

Temperature self-regulation and relaxation with migraine patients and normals

Ten migraine headache subjects and 10 non-migraine subjects were divided equally into two groups: a progressive relaxation group and a finger temperature biofeedback group. Finger temperature, temporal artery pulse amplitude and forehead blood flow were monitored for all subjects during two baseline and six treatment sessions.

The biofeedback group achieved greater (albeit low magnitude) increases in finger temperature than the relaxation group, but no improvement in headache activity was obtained. However the relaxation group improved significantly in terms of headache intensity.

There was no significant difference in the ability to achieve finger temperature control, nor in stability point temperatures, between the migraine and non-migraine subjects.

No systematic relationship was found between finger temperature, forehead blood volume and temporal artery pulse amplitude. Possible mechanisms of the therapeutic effects of finger temperature training are examined in the light of these results.     

Les théories implicites de l’intelligence : une question de perspectives ?

IntroductionImplicit theories of intelligence are beliefs that people form regarding the malleability of intelligence. The so-called “growth” and “fixed” mindsets respectively view intelligence as a characteristic that can or cannot be changed. Psychology, as a science, also offers diverging responses. The developmental and differential traditions in the study of intelligence merely provide different answers because they do not focus on the same sources of variability nor on the same dimensions of intelligence.ObjectivesThe research question that guided the present studies was: Are people's naïve theories influenced by the same factors that drive developmental and differential psychologists to different conclusions?MethodIn Study 1, we first assessed participants’ (n = 509) reference norm orientation (i.e. whether they tend to focus on individual or social comparison), using a task in which they had to predict the school results of an hypothetical child. Then we administered a French version of Dweck's (2007) mindset scale. In study 2, we first asked participants (n = 530) to choose between two definitions of intelligence focusing either on its fluid or crystalized dimensions. Then we administered the French Mindset Scale and asked participants to justify their conclusion.ResultsBoth variables of interest (reference norm orientation and preferred definition of intelligence) had a significant effect on the participant's incremental beliefs.ConclusionThe results of the two studies as well as the qualitative analysis of participants’ arguments suggest that mindsets, like scientific theories, partly stem from the fact that the same question regarding intelligence malleability can be approached with two different perspectives.     

Under what conditions do lay people and health professionals accept a breach of doctor-patient confidentiality regarding a patient with signs of terrorist radicalization?

IntroductionConfidentiality is crucial to the establishment of a strong patient-physician relationship. However, certain situations create a dilemma for the physician who is faced with the choice of either respecting medical confidentiality or protecting others from a serious risk of violence.ObjectiveThis study aimed to observe how lay people and health professionals assessed the acceptability of breaching confidentiality when a physician is confronted to a patient showing signs of terrorist radicalization.MethodA total of 228 participants (174 from the general population and 54 health professionals) judged the acceptability of 54 scenarios which were constructed through the orthogonal combination of 4 factors frequently mentioned in the literature: presence of a “Psychiatric disorder”; “Signs of radicalization”; “Projects of violence”; “Collegiality”. Variance and cluster analyses were performed on all the raw data.ResultsResults showed that all factors influenced the judgment of participants but that “Psychiatric disorders” had a weaker impact. Five clusters were identified: “Favorable if collegiality” (n = 23); “Favorable to breach confidentiality” (n = 77); “Unfavorable to breach confidentiality” (n = 26); “Sensitive to all factors” (n = 71); “Favorable if violence” (n = 31), respectively with mean ratings of 5.87, 8.42, 3.64, 6.30 and 7.16, on an acceptability scale of 0–10.ConclusionThe importance that the great majority of participants attribute to these factors indicates that they influence their judgments in this specific context.     

Perceived lack of training moderates relationship between healthcare providers’ personality and sense of efficacy in trauma-informed care

ABSTRACT

Background and Objectives: Medical patients often have trauma histories that are not routinely assessed, which can adversely affect health outcomes. Despite growing awareness of this issue, there is limited understanding of factors that influence provider competency in trauma-informed care (TIC). The study examined healthcare providers’ personality traits in relation to their sense of TIC efficacy, taking into account perceived barriers to TIC and professional quality of life.

Study Design: The study used cross-sectional survey methods to examine our central hypothesis that provider personality traits and perceived barriers to TIC would be associated with TIC-efficacy, and to explore interactions among study variables.

Methods: Survey data were collected from 172 healthcare providers examining TIC knowledge, TIC-efficacy, perceived barriers to TIC, personality traits, and professional quality of life.

Results: TIC-efficacy was positively correlated with “intellectence/openness” and inversely correlated with “neuroticism” and perceived lack of training as a barrier. “Intellectence/openness” interacted with perceived lack of training to predict TIC-efficacy, suggesting that providers with lower “intellectence/openness” report greater TIC-efficacy when lack of training is not perceived as a barrier.

Conclusions: Provider personality traits and perceived barriers to TIC appear related to providers’ TIC-efficacy. Implications for overcoming barriers to TIC through training and implementation are discussed.     

Treatment of bisexual pedophilia by a biofeedback-assisted self-control procedure

A bisexual pedophile was treated for 88 days using a biofeedback procedure which displayed his erection response to sexually deviant stimuli on a closed-circuit television monitor. Told to develop a strategy of self-control using the biofeedback, his response to young boys and girls was treated sequentially in a multiple baseline design. His concurrent response to boys, girls and adult males was evaluated in separate generalization sessions. The treatment was successful in suppressing deviant response while maintaining nondeviant response in strength. Debriefing of the client following treatment revealed that he had used a self-developed technique of covert sensitization to suppress deviant response and had used the biofeedback to confirm and validate this self-control strategy.     

Managers' life goals and their willingness to accept an international assignment

Abstract

The relationship between life goals and willingness to accept an international assignment is investigated. 109 British managers responded to a questionnaire which tapped their willingness to accept an assignment in various countries and for a variety of different types of organizations. Also they had to indicate the importance of 11 life goals (Exercise Life Goals; Bass, 1976). Two life goals were consistently related to willingness to work abroad, namely: “independence”, which was positively related to willingness to accept an international assignment; and “security”, which was negatively related. Less consistent patterns were found for “self-realization”, “duty”, “pleasure”, and “affection”.     

Headache triggers: To avoid or not to avoid,that is the question

Abstract

Traditional clinical advice in the management of headaches is to avoid trigger factors. There is a danger, however, that avoidance of triggers results in a sensitisation process whereby tolerance for the triggers decreases, in a manner analogous to increments in anxiety arising from avoidance of anxiety-eliciting stimuli. Reported here are six single-case experiments in which the aim was to desensitise headache sufferers to an experimentally validated trigger, namely “visual disturbance”. The results demonstrated that repeated, prolonged exposure to a headache trigger led to desensitisation with participants experiencing less visual disturbance, less negative affect and less head pain in response to the trigger. These findings have theoretical significance as they speak to the issue of the aetiology of chronic headache, and practical significance as they suggest that a key aspect of current management may contribute to the disorder becoming worse rather than better.
