On the development of knowledge during problem solving

A person might solve a problem progressing very quickly after an initial period of very little progress, as if new insight was suddenly gained, without that person possessing anything that merits being called insight. This is demonstrated in a series of studies as an extension of the experiments of Kotovsky and Simon (1990). A total of 68 undergraduate students solved an isomorph of the Chinese Ring Puzzle. The first study showed that the verbal protocols of participants thinking aloud contained accumulating explicit knowledge. In the second study, the participants' move records were analysed in a novel way, and it was shown that the choices of moves gradually improved. In the third study the knowledge about the puzzle was tested after the puzzle was solved. The participants demonstrated that they knew, although imperfectly, which move was possible in a given situation. The fourth study showed that verbalising did not alter problem solving profoundly. Together, the four studies demonstrated that solving the puzzle took place after a gradual development of knowledge, instead of a flash of insight.

A Cross-Cultural Comparison of Social Phobia Symptoms

This study examined two forms of social anxiety or phobia, social phobia as defined by DSM-IV and Taijin Kyofusho (TKS, a Japanese form of social anxiety), in relation to their respective culturally prescribed self-construals as independent and interdependent. Japanese university students (N = 124) and U.S. university students (N = 123) were administered the Social Interaction Anxiety Scale, the Social Phobia Scale, the TKS Scale, and the Self-Construal Scale. From the results of a hierarchical regression analysis, TKS symptoms are more likely to be expressed by individuals who are Japanese and individuals who construe themselves low on independence but high on interdependence. In addition, social phobia symptoms are more likely to be expressed by individuals who construe themselves low on independence but high on interdependence irrespective of culture. Implications for therapists from each culture who have clients who present social anxiety or phobia symptoms are discussed.     

Two sets of twins with selective mutism: neuropsychological findings.

Neuropsychological data are reviewed from two sets of dizygotic twins presenting with selective mutism characterized by situation specific anxiety, extreme passive behavior, lack of responsivity, lack of peer interaction, and a chronic course of selective mutism. Both sets of twins had a history of prematurity and delayed speech development. One set of twins presented with normal intelligence and normal receptive language skills but with expressive language and oral motor sequencing difficulties. The second set of twins presented with Verbal IQ deficits and significant receptive and expressive language deficits. A summary of current conceptualizations regarding etiology and treatment of selective mutism is provided.     

Overcoming Barriers to Collaboration Between Basic Behavioral Scientists and Public Health Scientists in Research on Mental Disorders

The behavioral and public health sciences both have a long and rich history supporting basic, translational, and applied research aimed at improving human lives and reducing human suffering. Through the complementary expertise of these disciplines, investigators have contributed to significant, worldwide improvements in mental and physical health. Further gains can be achieved through collaborative research among scientists in these 2 fields. Unfortunately, there are a number of barriers to such collaboration originating in different intellectual traditions, research methods, and the structure and values of academia. We identify these barriers and potential strategies for overcoming them. Several areas for future collaborative research appear promising, especially comorbid mental and physical disorders, adherence to interventions, stigma, and emotional processes. Theory-guided preventive interventions may represent especially fertile areas of collaborative effort.

Improving Health Care Utilization, Improving Chronic Disease Utilization, Health Status, and Adjustment in Adolescents and Young Adults with Cystic Fibrosis: A Preliminary Report

We conducted a randomized clinical trial of a 3-session written self-disclosure intervention for patients with cystic fibrosis (CF). Patients (n = 39) who were at least 15 years of age and diagnosed with CF participated in the intervention. Participants in the intervention arm were asked to write in the health care setting about an important emotionally distressing issue of personal significance for a 20-min period of time and two additional 20-min writing episodes at the patient's home, which were prompted by telephone calls. Patients in the control condition received standard care alone. Findings revealed that the intervention resulted in a reduction of the number of days patients spent in the hospital over a 3-month period. The intervention did not have an impact on physiological (Forced Expiratory Volume and Body Mass Index or subjective markers of health status. These findings extend those of Pennebaker's (cf., J. Smyth, 1998) demonstrating an effect of the written-self-disclosure intervention on health care utilization. These preliminary findings are promising and justify further investigation of the modified intervention in other chronic illness populations.     

A Study of Panic Attacks in University Students of Iran

This study examined the parameters of panic, fear, and avoidance among university students in Iran. Data were collected from 347 students using Farsi translations of the Panic Attack Questionnaire, Beck Depression Inventory, Taylor Manifest Anxiety Scale, State-Trait Anxiety Inventory, and Anxiety Sensitivity Index. Thirty-eight percent of participants reported panic attacks in the past year and 21.4% reported panic attacks in the past 4 weeks when prompted by a broad definition of panic. Men and those with unexpected panic reported greater panic severity whereas women with panic attacks reported greater situational fear and avoidance. Panickers who satisfied DSM-III-R panic disorder (PD) criteria reported greater lifestyle restriction and general psychopathology. The findings provide tentative support for cross-cultural similarity in panic phenomenology and the validity of DSM-III-R PD criteria among university students in Iran. The results are discussed by reference to nonclinical panic research and general themes of Iranian culture.
