Development and evaluation of an inventory to assess adult stutterers'' communication attitudes

The purpose of this study was to develop and evaluate a procedure to assess adult stutterers' communication attitudes. To this end, the investigation was divided into two phases. In Phase I, an assessment inventory based on a tripartite attitudinal model was developed and administered to 107 adult stutterers. Reliability and validity of these procedures were examined, and the inventory was refined. In Phase II, reliability and validity of the attitude assessment procedures were reassessed, and the attitudes of 26 stutterers and 56 nonstutterers were examined. Assessment procedures involved a self-report inventory, which obtained ratings of items in 13 situational subscales representing different speaking situations. These situations were rated using four response scales reflecting behavioral, affective, and cognitive aspects of attitude. Situational responding, response scale scores, and response scale interrelationships are examined. Findings are discussed in terms of the potential value of the inventory and future investigations.     

Cognition and Self-Control: Cognitive Control of Painful Sensory Input

Eighty Ss were first tested for base-level response to a pain-producing stimulus and then were re-tested on the same pain stimulus after receiving 1 of 8 experimental treatments. The 8 treatments were arranged in a 2 x 2 x 2 factorial design: presence or absence of hypnotic induction procedure; presence or absence of instructions for anesthesia; and presence or absence of demands for honest reports. Neither the hypnotic-induction procedure nor the demands for honesty affected the Ss'reports of the degree of pain experienced. The anesthesia instructions--"think of the hand as numb and insensitive as if it were a piece of rubber..."--produced an equal degree of pain reduction in hypnotic and non-hypnotic Ss and in Ss who were and those who were not exposed to demands for honesty. The results indicate that (a) Ss' reports of pain are less affected by demands for honesty and are more closely related to their actual experiences than has been previously assumed and (b) instructions which direct Ss to exercise cognitive control over painful sensory input are effective (with or without 'hypnosis') in reducing the experience of pain.     

Change after long-term psychoanalytic psychotherapy

Psychoanalytic psychotherapy in clinical practice is traditionally a long-term treatment conducted by well-trained psychotherapists. However, very few studies have been published that evaluate the effects of such treatment. To redress this lack of studies, 55 individuals selected for long-term psychoanalytic psychotherapy (average, 3 years) were invited to participate in a naturalistic study. The psychotherapists had a mean of 15 years of professional experience. The 36 patients who completed psychotherapy manifested a substantial reduction in symptomatic suffering and decreased levels of character pathology, as measured by the Karolinska Psychodynamic Profile (KAPP) and the Karolinska Scales of Personality. Generally, such changes were not found in the individuals who did not engage in treatment. In the therapy group, improvements were found on eight KAPP subscales defining different aspects of character: Intimacy and Reciprocity, Frustration Tolerance, Regression in the Service of the Ego, Coping with Aggressive Affects, Conceptions of Bodily Appearance and their Significance for Self-esteem, Sexual Function, Sexual Satisfaction, and Personality Organization. The results indicate that individuals who engaged in psychotherapy improved their capacity to handle crucial aspects of life and reduced their symptomatic suffering.     

Spontaneous and learned turning behaviour in food- or water-restricted hooded rats

Some laboratory studies have suggested that whereas food restriction in animals leads to response alternation (behavioural flexibility), water restriction induces perseverative, stereotyped responding. Hooded rats, restricted to 1 hour per day access to either food or water, were tested on a radial-arm maze (using a procedure that eliminates algorithmic response strategies), for alternation in a 3-arm maze (both when the maze was familar and unfamilar, and with or without differential reward) and a 2-choice maze in which some animals were taught to alternate direction of turn, and others to perseverate. Both groups performed the radial-arm maze task competently and spontaneously alternated at a high rate. In the learned task, food-restricted rats were slower than water-restricted to reverse a consistent direction of turn; in the alternation condition, water-restricted rats developed a temporary, but strong, directional bias when making their first choice each day. Water-restricted subjects took water more readily than food-restricted took food when initially introduced to the apparatuses, but there was no consistent difference in motivation in the two conditions. The results provide little support for the notion that distinct cognitive-motivational states or behavioural strategies are induced by food- and water-restriction.     

Influence of spatial environment on maze learning in an African mole-rat

In subterranean species where excavation is energetically expensive, efficient spatial navigation is vital to reducing the costs of locating important resources such as food and mates. While spatial navigational ability is positively correlated with sociality in subterranean mammals, we have a less clear understanding of the role of habitat complexity on navigational ability. We tested spatial navigational ability and memory in 12-18-month captive Natal mole-rats (Cryptomys hottentotus natalensis) maintained in a simple environment with no environmental enrichment and newly captured wild individuals from natural, complex burrow systems. In maze trials, mole-rats captured freshly from the wild made significantly fewer navigational errors, were more likely to successfully navigate the maze, travelled shorter distances and as a consequence, completed the maze in less time. Male mole-rats from both experimental treatments were more likely to complete the maze than females. Memory retention of the maze was tested on day two, seven, 30 and 60, respectively. The results were variable, although both groups showed a significant memory retention 60?days after testing. Our results highlight the potential importance of the environment (microhabitat complexity) on spatial cognitive performance in mole-rats.     

Addressing Challenges in Individual Psychotherapy with Delusional Patients: A Case Study

Although cognitive-behavioral treatments for schizophrenia and other psychotic disorders demonstrate strong results in clinical trials, not all patients respond to these treatments. Common challenges in psychotherapy with delusional patients include a mismatch between the therapist’s and the patient’s expectations about the purpose of therapy, the patient’s lack of motivation to reduce delusional beliefs in service of other goals, and the patient’s dependence on the delusions in order to preserve an intact sense of self. This case highlights the value of integrating a psychodynamic perspective with cognitive-behavioral interventions to address challenges in psychotherapy with chronically delusional patients.     

THE INFLUENCE OF MOTIVATING OPERATIONS ON GENERALIZATION PROBES OF SPECIFIC MANDS BY CHILDREN WITH AUTISM

We investigated the influence of motivating operations on the generalization of newly taught mands across settings and communication partners for 3 children with autism. Two conditions were implemented prior to generalization probes. In the first condition, participants were given access to a preferred item until they rejected the item (i.e., abolishing operation). In the second condition, the item was not available to participants prior to generalization probes (i.e., establishing operation). The effects of these conditions on the generalization of newly taught mands were evaluated in a multielement design. Results indicated differentiated responding during generalization probes in which more manding with the target mand was observed following the presession no‐access condition than in the presession access condition. These results support the consideration of motivating operations when assessing generalization of target mands to various untrained contexts.     

Process timing and its relation to the coding of tonal harmony

Advances in auditory research suggest that gamma-band synchronization of frequency-specific cortical loci could be responsible for the integration of pure tones (harmonics) into harmonic complex tones. Thus far, evidence for such a mechanism has been revealed in neurophysiological studies, with little corroborative psychophysical evidence. In six experiments, we observed a rate- and time-specific response-time advantage for a sequence of target pips when the defining frequency of the target was a fractional multiple of a priming frequency. The effect was only observed when the prime and target sequences were presented at 33 pips per second and when the interstimulus interval was approximately 100 and 250 ms. This evidence implicates oscillatory gamma-band activity in the representation of harmonic complex tones and suggests that synchronization with precise temporal characteristics is important for disambiguating related harmonic templates. An outline of a model is presented, which accounts for these findings in terms of fast resynchronization of relevant neuronal assemblies.     

Attachment and Mother-Child Communication in Adjustment to the Death of a Father Among Cambodian Adolescents

This study examined quality of attachment to the mother and child-mother communication in adolescents' adjustment to the death of a father. Forty-eight Cambodian adolescents whose father had died within the previous 3 years completed a set of measures that included attachment, communication, grief, and self-esteem. Results showed that quality of attachment to the mother and whether the adolescent communicated with the mother about the father and found this to be helpful were positively related to adaptive grief and self-esteem. Moreover, support was shown for an indirect effect of quality of attachment to the mother on adaptive grief as mediated by communication. Implications of the findings for quality of attachment in adjustment to bereavement in a non-Western cultural context are discussed.
