The recognition of psychological disturbance in a sexually transmitted diseases clinic.

This study examined the rate of psychological disturbance in a series of new patients attending a clinic for sexually transmitted diseases. Forty three per cent of patients were identified as probable psychiatric cases by the General Health Questionnaire. Medical staff in the clinic were asked to assess patients' level of psychological disturbance. Disagreement between GHQ and doctors' ratings occurred in 41% of patients. Some patient and doctor characteristics were examined that might be associated with disagreement, and the results are discussed in terms of possible social--psychological influences upon doctors' recognition of psychological disturbance.

Frequency of consultations and general practitioner recognition of psychological symptoms.

BACKGROUND: General practitioners (GPs) are widely reported to 'miss' half of the psychological problems present in their patients. AIMS: To describe the relationship between frequency of consultations and GP recognition of psychological symptoms. DESIGN OF STUDY: Survey of GPs and their patients. SETTING: General practices in the southern part of New Zealand's North Island. METHOD: Participants were randomly selected GPs (n = 70), and their patients (n = 3414, of whom a sub-set of 386 form the basis of this study). The main measure was the comparison between GP and composite international diagnostic interview (CIDI) recognition of psychological problems. RESULTS: Of the GPs selected, 90% participated. The CIDI was completed by 70% of selected patients. In patients (n = 386) with a CIDI-diagnosed disorder, 63.7% (95% confidence interval [CI] = 53.3 to 74.1) were considered by the GP to have had psychological symptoms in the last year; 40.1% (CI = 31.0 to 49.2) to have had clinically significant psychological problems, and 33.8% (CI = 24.9 to 42.6) were given an explicit diagnosis. However, in those CIDI-diagnosed patients who had been seen five or more times during the previous year, these recognition figures increased to 80.2% (CI = 68.9 to 91.4), 59.4% (CI = 45.9 to 72.9) and 53.6% (CI = 40.1 to 67.1) respectively, and dropped to 28.8% (CI = 13.0 to 44.7), 13.6% (CI = 3.4 to 23.7), and 10.7% (CI = 1.4 to 19.9) among patients not consulting during the previous year. GPs often differed from the CIDI in their assessment of clinical significance and diagnosis. CONCLUSION: GP non-recognition of psychological problems was at a problematic level only among patients with little recent contact with the GP. Efforts to improve GP recognition of mental disorder may be more effective if they target new or infrequent attenders, and encourage patient disclosure of psychological issues.

Determinants of general practitioner recognition of psychological problems in a multi-ethnic inner-city health district.

BACKGROUND: With few exceptions, evaluation of the capacity of general practitioners (GPs) to recognise psychiatric disorder in their patients has failed to consider the role of ethnic diversity in the consultation process and whether such knowledge can improve understanding of the degree to which psychiatric morbidity is recognised within GP settings. METHODS: This research was completed in five general practices representative of all those within an inner-city health district. Psychiatric morbidity in patients consecutively attending the practices was then assessed using the General Health Questionnaire; in addition, GPs were asked to complete a checklist of current problems identified during each consultation. RESULTS: Analysis suggested that Asian and Black patients were less likely than White patients to have psychological problems identified; that social problems and a psychiatric history facilitated recognition; and that current physical illness hindered recognition. CONCLUSIONS: GP recognition of psychological problems varies according to patient ethnicity but can be substantially masked by both the physical and social circumstances of patients at consultation.

Evaluation of an educational programme to improve the recognition of psychological illness by general practitioners.

BACKGROUND: Take Care is a commercially sponsored educational package for the detection and management of depression by all members of the primary health-care team. AIM: This study was designed to evaluate whether the educational package affects the recognition of psychological illness by general practitioners. METHOD: General practitioners working in 13 practices in North West England or Trent Regional Health Authorities took part the evaluation. Patients who scored more than eight on the depression or anxiety component of the Hospital Anxiety and Depression (HAD) scales, and who were thought by their general practitioner to have a totally physical problem or no illness, were deemed to have a psychological illness that had been 'missed' by the doctor. Changes in the proportion of missed cases before and after exposure to Take Care were estimated. RESULTS: When all practices were considered together, the general practitioners missed a depressive illness in 24.1% of patients before Take Care, and 17.1% afterwards; absolute decrease 7.0% [95% confidence interval (CI) -2.0 to -12.0%]. An improvement was seen in most practices (Wilcoxon matched-pair test P < 0.05). The programme was also associated with a small reduction in the overall proportion of episodes of anxiety missed by the doctor (absolute decrease 4.5%; 95% CI -1.0 to -8.0%) a reduction was found in most practices (Wilcoxon matched-pair test P < 0.05). There was no material difference in the diagnostic false-positive rate of the doctors before and after the introduction of the programme. CONCLUSION: Exposure to an educational package for depression was associated with improved recognition of psychological illness by general practitioners.

Recognition of psychological and cognitive impairments in the emergency department.

Ninety-six patients presenting to a university hospital emergency department were screened before triage for psychological symptoms or cognitive impairment using the General Health Questionnaire (GHQ) and Mini-Mental State examination (MMS). Charts were reviewed for demographic information and emergency physicians' recognition of psychological symptoms or cognitive dysfunction. Of the patients studied, 38% had positive results on the GHQ, and 18% had positive results on the MMS. Psychological symptoms or cognitive impairments were recognized by the emergency physicians in only 8% of those with positive GHQ results and 6% of those with positive MMS results. The usefulness of screening measures for psychological symptoms and cognitive impairment of emergency department patients is discussed.

When is all understood and done? The psychological reality of the recognition point.

Using lexical decision, the effects of primes of different length on spoken word recognition were evaluated in three partial repetition priming experiments. Prime length was determined via gating (Experiments 1a and 2a). It was shorter than, equivalent to, or longer than the recognition point (RP), or a complete word. In Experiments 1b and 1c, priming increased with prime length and was independent of reaction time. The influence of sensory information following the RP was investigated in Experiment 2b. Latencies decreased with increasing prime length, but priming decreased only for complete words. RP and complete words have a special status. Lexical representations are activated to different degrees at the RP and at word offset.

In search of cerebral error detectors.

Multiunit activity was recorded from 124 different subcortical sites in 10 parkinsonian patients bearing gold electrodes for diagnosis and therapy. The patients participated in a visual recognition task in which the stimuli (digits) were presented on a LED-matrix at threshold, the exposure times so chosen that in about half the trials the patient failed to recognize the digit correctly. Peristimulus time histograms (PSTHs) for each neuronal population as well as profiles of reactions for all neuronal populations were calculated and statistically analysed, separately for the cases of correct, incorrect, and non-recognition. There are at least 3 groups of neuronal populations, each associated with one temporally separate neurophysiological process involved in the performance of the psychological recognition task. They can be differentiated by the parameters' 'onset' and 'peak' latency. This in itself suggests that they may be related to different psychological processes involved in the task's performance, the earlier components in feature detection and/or evaluation operations concerning the stimulus; the later components, presumably, in processes related to initiation of the actual response. By scanning the individual PSTHs, we found one neuronal population which might be considered an error detector. This population reacted robustly in the early stages of information processing (100-500 ms post-stimulus) only in the case of non-optimal behavior, suggesting that it might somehow be related to signalling an error.

Physician recognition of behavioral, psychological, and social aspects of medical care.

Recognition of house officers of easily detectable medication noncompliance, psychiatric disturbances, and recent stressful life events was assessed by means of a structured interview with each patient immediately following the clinic visit, a physician questionnaire, and chart review. The study included 235 patients and 58 interns and residents in internal medicine. Although the house officers were informed of the intent of the study and had their performance reviewed weekly, they failed to recognize 79% of the underconsumption of regular medications, 34% of psychiatric disturbances, and 76% of patients' recent stressful events. Possible explantations for their failures to recognize these behavioral, psychological, and social factors include lack of awareness of their importance, lack of time and skills necessary for their identification, and inability to manage these problems. None of these explantations, however, adequately justifies such results.

The recognition, diagnosis, and treatment of mental disorders by primary care physicians.

A valid and reliable vignette-based measure of DSM-III psychiatric diagnostic knowledge was administered to practicing primary care physicians (PCPs; generally, internal and family practice medicine) and mental health professionals (MHPs, in psychiatry and psychology). Recognition, diagnosis, and treatment recommendations were measured for 14 different disorders. Contrary to other reports, PCPs consistently recognized the presence of mental disorder and did so virtually as well as MHPs, although both PCPs and MHPs showed more under-recognition than over-recognition. Diagnostic accuracy, however, was substantially lower, with that of MHPs exceeding PCPs for the general classes of affective, anxiety, somatic, and personality disorders, but not for the organic disorders. In making specific diagnoses, significantly fewer PCPs than MHPs gave an accurate diagnosis for eight of the 14 disorders: dysthymic disorder, major depression with psychotic features, agoraphobia with panic attacks (marginally), generalized anxiety disorder, adjustment disorder with anxious mood (marginally), psychologic factors affecting physical condition, and two personality disorders. Overall, PCPs were most accurate in identifying organic disorders (81% correct), least accurate in identifying the personality disorders (14%), and intermediate in identifying the affective (47%), anxiety (49%), and somatic disorders (49%). In most cases, both PCPs and MHPs preferred referral to treatment in primary care, but more PCPs than MHPs recommended treatment in primary care for certain anxiety and somatic disorders. Some differences in the recommended use of antidepressants in primary care were also found. Implications for the provision of mental health care by primary care physicians are discussed.

On the psychology of the recognition heuristic: retrieval primacy as a key determinant of its use.

The recognition heuristic is a prime example of a boundedly rational mind tool that rests on an evolved capacity, recognition, and exploits environmental structures. When originally proposed, it was conjectured that no other probabilistic cue reverses the recognition-based inference (D. G. Goldstein & G. Gigerenzer, 2002). More recent studies challenged this view and gave rise to the argument that recognition enters inferences just like any other probabilistic cue. By linking research on the heuristic with research on recognition memory, the authors argue that the retrieval of recognition information is not tantamount to the retrieval of other probabilistic cues. Specifically, the retrieval of subjective recognition precedes that of an objective probabilistic cue and occurs at little to no cognitive cost. This retrieval primacy gives rise to 2 predictions, both of which have been empirically supported: Inferences in line with the recognition heuristic (a) are made faster than inferences inconsistent with it and (b) are more prevalent under time pressure. Suspension of the heuristic, in contrast, requires additional time, and direct knowledge of the criterion variable, if available, can trigger such suspension.

Musical training-induced functional reorganization of the adult brain: functional magnetic resonance imaging and transcranial magnetic stimulation study on amateur string players.

We used the combined technique of functional magnetic resonance imaging (fMRI) and transcranial magnetic stimulation (TMS) to observe changes that occur in adult brains after the practice of stringed musical instruments. We carried out fMRI on eight volunteers (aged 20-22 years): five novices and three individuals who had discontinued practice for more than 5 years. The motor paradigm contained a repetitive lift-abduction/fall-adduction movement of the left/right little finger, carried out with maximum efforts without pacing. The sensory paradigm was to stimulate the same little finger using a string. In parallel to the fMRI acquisition, TMS motor maps for the little finger were obtained using a frameless stereotactic neuronavigation system. After the baseline study, each participant began to learn a stringed instrument. Newly developed fMRI activations for the left little finger were observed 6 months after practice at multiple brain regions including inferior parietal lobule, premotor area (PMA), left precuneus, right anterior superior temporal gyrus, and posterior middle temporal gyrus. In contrast, new activations were rarely observed for the right little finger. The TMS study revealed new motor representation sites for the left little finger in the PMA or supplementary motor area (SMA). Unexpectedly, TMS motor maps for the right little finger were reduced significantly. Among new fMRI activations for sensory stimuli of the left little finger, the cluster of highest activation was located in the SMA. Collectively, these data provide insight into orchestrated reorganization of the sensorimotor and temporal association cortices contributing to the skillful fingering and musical processing after the practice of playing stringed instruments.

Perceptual priming for upright and inverted faces in infants and adults.

Based on recent models of the ontogeny of memory (Nelson, 1995), we hypothesize that 6-month-old infants should show evidence of repetition priming. Event-related potentials were recorded from 11 scalp sites to novel and primed upright and inverted faces. In Experiment 1 (n = 24), 6-month-old infants viewed faces that were repeated after 6 to 12 images. Overall, repeated faces demonstrated greater negativity than novel faces and upright faces demonstrated greater negativity than inverted faces. In order to ground these results in an adult model, a group of adults (n = 30) was tested in a similar experiment. Here we observed effects of repetition at an early positive component labeled the P150 as well as at the P300, with repeated images being more positive than novel images. These data support the idea that infants at 6 months are capable of revealing electrophysiological evidence of perceptual priming.

Anatomical functional and cognitive determinants of semantic memory disorders.

Contemporary debates on the 'semantic memory' construct revolve around three main topics: (1) the functional and anatomical relationships between episodic and semantic memory; (2) the format of semantic representations and their relationships with the underlying sensory-motor processes; (3) the categorical organization of semantic memory. The aim of the present review is to demonstrate that there is a common thread linking these different aspects of semantic memory. This thread is represented by the interdependence of mechanisms involved in the construction of semantic memory and the content of semantic representations. In particular, I suggest there is a continuity between: (a) the mechanisms of acquisition of episodic and semantic memory; (b) semantic representations and sensory-motor processes preliminary to the acquisition of these representations. This continuity has important implications for the format of semantic representations and the brain structures subserving the organisation of various categories of knowledge.

Semantic relevance, domain specificity and the sensory/functional theory of category-specificity.

According to the sensory/functional theory of semantic memory, Living items rely more on Sensory knowledge than Non-living ones. The sensory/functional explanation of category-specificity assumes that semantic features are organised on the basis of their content. We report here a study on DAT patients with impaired performance on Living items and tests of Sensory knowledge, and show that this impairment not only disappears after parcelling out semantic relevance, but is also reversed if this parameter is appropriately manipulated. Although semantic relevance model predicts these results [Sartori, G., & Lombardi, L. (2004). Semantic relevance and semantic disorders. Journal of Cognitive Neuroscience, 16, 439-452], they run counter to both the sensory/functional theory and the domain-specific theory of category-specific impairment.

Salivary alpha-amylase response to competition: relation to gender, previous experience, and attitudes.

This study examined individual differences in salivary alpha-amylase response to competition in relation to gender, previous experience, behavior, attitudes, and performance. Participants were 42 (21 women) members of a collegiate crew team. Saliva samples were collected before, 20- and 40-min post-ergometer competition and at the same times on a non-competition day for comparison. Samples were assayed for salivary biomarkers of sympathetic nervous system (alpha-amylase) and hypothalamic-pituitary-adrenal axis (cortisol) activity. Behavioral assessments included self-reports of dominance, competitiveness, bonding with teammates, competition-related strategic thinking, and performance. On average, salivary alpha-amylase increased 156% in response to the ergometer competition. By comparison, cortisol increased 87% across the same time period. Salivary alpha-amylase was higher across the competition for varsity than for novice athletes, and was positively associated with performance and interest in team-bonding. Regression analyses revealed that alpha-amylase reactivity explained individual differences in dominance and team bonding above and beyond that associated with cortisol reactivity, and that joint inactivation in alpha-amylase and cortisol reactivity to competition (low-low) was associated with high perceived dominance. The findings are among the first to integrate salivary alpha-amylase into the study of competition and reveal that intra-individual change in alpha-amylase may be influenced by a confluence of factors that include contextual, behavioral, and psychological factors and processes.
