Event-related potentials, cognition, and behavior: a biological approach.

The prevailing cognitive-psychological accounts of event-related brain potentials (ERPs) assume that ERP components manifest information processing operations leading from stimulus to response. Since this view encounters numerous difficulties already analyzed in previous studies, an alternative view is presented here that regards cortical control of behavior as a repetitive sensorimotor cycle consisting of two phases: (i) feedforward anticipation and (ii) feedback cortical performance. This view allows us to interpret in an integrative manner numerous data obtained from very different domains of ERP studies: from biophysics of ERP waves to their relationship to the processing of language, in which verbal behavior is viewed as likewise controlled by the same two basic control processes: feedforward (hypothesis building) and feedback (hypothesis checking). The proposed approach is intentionally simplified, explaining numerous effects on the basis of few assumptions and relating several levels of analysis: neurophysiology, macroelectrical processes (i.e. ERPs), cognition and behavior. It can, therefore, be regarded as a first approximation to a general theory of ERPs.

Maternal criticism, mother-child interaction, and bronchial asthma.

The study investigated maternal critical attitude (CA) and negative mother-child communication in families with an asthmatic child and in controls. Twenty-five children with bronchial asthma (7-13 yr) and 25 healthy children with their mothers participated in the project. Mothers were asked to describe their child (Five Minute Speech Sample; FMSS). Additionally mother and child discussed a mutual problem (Problem Discussion; PD). Videorecordings were taken. CA was assessed from the mothers' responses during FMSS. Negative verbal behavior during PD was coded for mother and child. During FMSS significantly more mothers of the asthmatic children than of the controls showed CA. During PD mothers of the asthmatic children made significantly more critical remarks than their controls. Within the asthmatic group, CA mothers showed significantly more criticisms than those with non-CA. Significantly more long sequences of negative verbal interaction occurred in mother-child-dyads with a CA mother than in those with a non-CA mother.

Lateralizing value of postictal automatisms in temporal lobe epilepsy.

PURPOSE: To describe clinical characteristics and lateralizing value of postictal automatisms in patients with temporal lobe epilepsy (TLE). METHODS: One hundred and ninety-three videotaped seizures of 55 consecutive patients with refractory TLE and postoperatively seizure-free outcome were analyzed. Ictal as well as postictal (manual, oral and speech) automatisms were monitored. RESULTS: Thirty-four (62%) of the 55 patients showed PA at least once during their seizures. Postictal automatism was observed in 70 (36%) attacks as manual (21%), oral (13%) or speech (9%) automatisms. Fifteen seizures contained a combination of two different postictal automatisms. The presence of postictal oral automatisms did not lateralize the seizure onset zone (p=0.834). Speech automatisms (repetitive verbal behavior) occurred more frequently after left-sided seizures (p=0.002). Postictal unilateral manual automatism showed no lateralizing value occurring by the ipsilateral hand in 10 and the contralateral upper limb in 6 seizures (p=0.454). CONCLUSION: : Postictal automatism is a relatively frequent phenomenon in TLE. Postictal speech automatism lateralizes the seizure onset zone to the left hemisphere. Our observation can help the presurgical evaluation of TLE because verbal perseveration frequently occurs spontaneously, even in seizures without appropriate postictal language testing.

Early language and intelligence development and their relationship to future criminal behavior.

The relationship between intelligence, measured regularly from the ages of 3 to 17 years, and registered criminality was investigated for boys (N = 122) in a birth-to-maturity study. Significant negative correlations appeared at several ages, even for intelligence assessed as early as at the age of 3. The hypothesis was advanced that the early language development of the boys would be negatively associated with future criminality. Information on language development, obtained by applying the Brunet-Lézine psychomotor developmental test for infants, substantiated this hypothesis. Significant correlations with registered criminality appeared for language development at 6, 18, and 24 months. Further support for the hypothesized link was provided by psychologists' ratings of children's verbal behavior and by maternal reports of their child's speech at the ages 3 to 5. The role of early language retardation in contributing to later criminality is discussed.

Videotape and verbal feedback in behavioral couple therapy: a review.

Reviewed the experimental evidence for the efficacy of videotape and verbal feedback in behavioral couple therapy; it is concluded that research to date does not permit definitive conclusions concerning the efficacy of either procedure. Studies on behavioral differences between happy and distressed couples also were summarized. The evidence indicates that it is, as yet, difficult to ascertain just how the communication behaviors of happy and distressed couples differ.

The expression and understanding of jealousy in children with autism.

We investigated the expression and understanding of jealousy in 16 high-functioning children with autism and 17 typically developing children matched for IQ, chronological age, gender, and maternal education. We examined the expression of jealousy via children's behaviors, verbalizations, and affects demonstrated during two jealousy-provoking triadic scenarios (drawing and playing) enacted among the child in the experimental group (autism or typical), that child's main caregiver (mostly mothers), and a familiar peer or sibling. The two scenarios corresponded with the two types of jealousy described in past studies: social-comparison jealousy (drawing scenario) and social-relational jealousy (playing scenario). To tap children's understanding, we asked them to identify jealousy from a picture, to provide examples of times they felt jealous, and to offer suggestions for coping with jealousy. The main results revealed that children with autism expressed jealousy in situations similar to their typical age mates but manifested it in different behaviors. Moreover, children with autism revealed a less coherent understanding of the feeling. We discuss the meaning of the gap between demonstrating and understanding jealousy in light of the two central theoretical views conceptualizing the core emotional deficit in children with autism.

Implementation of a scheduled toileting program in a long term care facility: evaluating the impact on injury risk to caregiving staff.

This study evaluated the impact of a scheduled toileting program on the risk of injury to caregivers and on resident agitation or aggressive behaviors. Injury data, ergonomic assessments, staff questionnaires, and resident agitation checklists were used to evaluate the program in a 75 bed unit, with a similar unit acting as a comparison. The program resulted in an increased percentage of residents toileted regularly in the intervention unit, while aggressive incidents declined in both groups. Staff in the intervention unit reported a significantly lower perceived risk of injury to the head and neck than the comparison group. Although the program resulted in increased workload to manage multitasking, monitor an additional aspect of scheduled care, and perform more toileting transfers, overall risk of physical injury was reduced. The toileting program, a shift toward resident focused care, and enhanced agitation awareness combined to reduce resident handling injuries and resident agitation expressed as verbal behaviors or emotional upset, but not as physical behaviors. Clear communication, mentoring, and monitoring were important for successfully changing care practices.

Patient trust: is it related to patient-centered behavior of primary care physicians?

BACKGROUND: Patients' trust in their health care providers may affect their satisfaction and health outcomes. Despite the potential importance of trust, there are few studies of its correlates using objective measures of physician behavior during encounters with patients. METHODS: We assessed physician behavior and length of visit using audio tapes of encounters of 2 unannounced standardized patients (SPs) with 100 community-based primary care physicians participating in a large managed care organization. Physician behavior was assessed via 3 components of the Measure of Patient-Centered Communication (MPCC) scale. The Primary Care Assessment Survey (PCAS) trust subscale was administered to 50 patients from each physician's practice and to SPs. We used multilevel modeling to examine the associations between physicians' Patient-Centered Communication during the SP visits and ratings of trust by both patients and SPs. RESULTS: Component 1 of the MPCC, which explored the patient's experience of the disease and illness, was independently associated with patient's rating of trust in their physician. A I SD increase in this score was associated with 0.08 SD increase in trust (95% confidence interval 0.02-0.14). Each additional minute spent in SP visits was also independently associated with 0.01 SD increase in patient trust. (95% confidence interval 0.0001-0.02). Component 1 and visit length were also positively associated with SP trust ratings. CONCLUSIONS: Physician verbal behavior during an SP encounter is associated with trust reported by SPs and patients. Research is needed to determine whether interventions designed to enhance physicians' exploration patients' experiences of disease and illness improves trust. Key Words: physician-patient relationship, patient-centered care, trust, physician behavior

Parasomnias.

Parasomnias are defined as unpleasant or undesirable behavioral or experiential phenomena that occur predominately or exclusively during the sleep period. Initially thought to represent a unitary phenomenon, often attributed to psychiatric disease, it is now clear that parasomnias are not a unitary phenomenon but rather are the manifestation of a wide variety of completely different conditions, most of which are diagnosable and treatable. The parasomnias may be conveniently categorized as "primary sleep parasomnias" (disorders of the sleep states per se) and "secondary sleep parasomnias" (disorders of other organ systems, which manifest themselves during sleep). The primary sleep parasomnias can be classified according to the sleep state of origin: rapid eye movement (REM) sleep, non-REM (NREM) sleep, or miscellaneous (i.e., those not respecting sleep state). The secondary sleep parasomnias can be further classified by the organ system involved. The underlying pathophysiology of many parasomnias is state dissociation-the brain is partially awake and partially asleep. The result of this mixed state of being is that the brain is awake enough to perform very complex and often protracted motor and/or verbal behaviors but asleep enough not to have conscious awareness of, or responsibility for, these behaviors.

"Spontaneous" transfer of stimulus control from tact to mand contingencies.

An important issue in teaching verbal behavior to persons with severe handicaps is the transfer of stimulus control from tact (e.g., naming) to mand (e.g., requesting) relationships. Previous research has shown that topographies taught as tacts frequently fail to appear as mands unless transfer between these two response classes is explicitly programmed. Procedures promoting this transfer would provide a necessary instructional tool. Transfer from tact to mand contingencies was investigated in two adults with severe mental retardation. Correct pointing responses to line drawing symbols depicting the utensils required to access previously requested food (beverage) items were assessed prior to and following tact intervention. Mands for two of three utensils emerged following tact intervention. The results suggest transfer from tact variables to the conditioned establishing operation may be facilitated by the prior development of a minimal mand repertoire.

Generalization of verbal conditioning to verbal and nonverbal behavior: group therapy with chronic psychiatric patients.

TWELVE CHRONIC HOSPITALIZED FEMALE PATIENTS RECEIVED TOKEN REINFORCEMENT CONTINGENT ON TWO SEPARATE CLASSES OF VERBALIZATIONS: (a) positive statements about optional activities available in the hospital setting, and (b) positive statements about people. Cross-class generalization of reinforced verbal responses about activities to overt behavior was tested by actual participation in activities; within-class generalization of verbal responses about people to verbalizations in another stimulus setting was assessed in a structured interview situation. A multiple baseline design with contingency reversals was employed to demonstrate experimental control of both classes of verbalizations in the group sessions. Positive statements about activities generalized to actual participation in activities, while generalization of positive statements about people to verbalization in the extragroup setting did not occur.

The validity of psychometric instruments for detection of dementia in the elderly general population.

OBJECTIVE: To compare the validity of different instruments for screening and diagnosis of dementia and to provide threshold scores for these purposes, ie screening focusing on a high sensitivity and diagnosis focusing on a high specificity. SETTING: 287 subjects from a general population sample who had completed more than one of these psychometric tests. METHODS: The performances of the Structured Interview for the Diagnosis of Dementia of the Alzheimer Type, Multi-Infarct Dementia and Dementias of Other Aetiology according to ICD-10 and DSM-III-R, the Mini-Mental State Examination, the Blessed Dementia Rating Scale, the Global Deterioration Scale, the Verbal Fluency Test, the Word list Learning Task, the Trail Making Test and the Labyrinth Test were compared using receiver operating characteristics analysis. RESULTS: The validity of composite instruments for the discrimination of dementia and cognitive health was higher than the validity of individual tests. However, some cognitive tests, ie verbal fluency and immediate recall of words, reached a high validity, making them useful and short screening instruments for dementia. CONCLUSION: There is no perfect instrument for screening and diagnosis of dementia. Different threshold scores for different purposes were provided in the present study. Recommendations for improving the validity of the Delayed Word List Learning Task for discriminating dementia and cognitive health include the expansion of list length and shortening of delay.
