Interfacing Apple and IBM computers for the analysis of clinical biofeedback

This paper demonstrates a method of transferring research data from a remote clinic to a large university mainframe for data manipulation and statistical analysis. Data collected by an Apple //e computer were transferred to an IBM 3031 mainframe by sending data files to an IBM PC by telephone modem or by direct hardwire connection to the PC. The IMB PC performed data-formatting routines and then uploaded the files to the mainframe for storage. Advantages and disadvantages of sending data over telephone lines via a modem are discussed.     

Single-subject statistical analysis of computer-assisted biofeedback

Single-subject statistics were used to analyze physiological data [electromyographic (EMG) temperature] recorded from two patients receiving computer-assisted biofeedback treatment in a clinic. When the data were analyzed by an ANOVA method or a regression technique, the results demonstrated that both patients learned to significantly reduce EMG levels. The rationale of using single-subject statistics is discussed, and the applicability of the statistical technique to the clinic population is illustrated.     

Ethnicity of Defendants and Jurors as Influences on Jury Decisions1

To assess the influence of ethnicity on jury decisions, 480 subjects viewed a videotaped trial of an Anglo or Hispanic defendant. Anglo or Hispanic majority 6-person juries deliberated until a unanimous verdict was reached. The juries that convicted the defendant were asked to determine sentence length and to provide a probation/ parole recommendation. Anglo majority juries convicted the defendant significantly more (M= 79%) than did the Hispanic majority juries (M= 52%), x²= 5.45, p < 0.02. No main effect of defendant ethnicity was obtained, but there was an interaction between the defendant and the jury's ethnicity, x²= 5.41, p < 0.02. Anglo majority juries were more lenient with the Anglo defendant, but the Hispanic majority juries did not differ in their conviction rates. No significant effects were obtained for sentence length. Differences in probation/parole recommendations were a function of jury ethnicity, F(l, 15) = 4.74, p < 0.05. Anglos were more likely to recommend that the defendant serve the full term of the sentence. These results are interpreted in terms of stereotyping and are discussed regarding their implications for a defendant's constitutional right to a fair trial.     

Assessment of attention deficit disorder using a thematic apperception technique

Attention deficit-hyperactivity disorder (AD-HD) is regarded as being relatively common among school-age children, but the literature reveals a number of confounding factors with standard assessment techniques of the disorder. Using a structured thematic apperception technique (the Tell-Me-A-Story [TEMAS] test) to measure attention to pictorial stimuli depicting characters, events, settings, and covert psychological conflicts, a study was conducted with 152 normal and 95 clinical Hispanic, Black, and White school-age children. Results reveal that the AD-HD children are significantly more likely than normal children to omit information in the stimuli about characters, events, settings, and psychological conflicts. Differences between the groups are large and persistent in the presence of structured inquiries by the test examiners. Results suggest the potential utility of structured thematic apperception techniques for the assessment of AD-HD, eventually to facilitate DSM-III-R (American Psychiatric Association, 1987) diagnosis, but also to invite closer scrutiny in carefully controlled validity studies.     

Interpersonal Psychotherapy—Adolescent Skills Training With Youth From Asian American and Immigrant Families: Cultural Considerations and Intervention Process

Although research has identified effective evidence-based depression prevention interventions for diverse youth, little is known about how the intervention process unfolds with immigrant family youth. This study utilized a qualitative approach to explore cultural and clinical differences in the implementation of Interpersonal Psychotherapy–Adolescent Skills Training (IPT-AST) in two schools, one serving youth from primarily immigrant, Asian American families and the second, youth from mostly nonimmigrant, non-Hispanic White families. A total of 131 IPT–AST sessions were audio recorded, transcribed, and coded for presence and patterns of cultural and clinical constructs. Results revealed that sessions with immigrant family youth were more likely to contain discussions of interpersonal problems characterized by estrangement, goals of spending time together with important others, mentions of emotion suppression and academic achievement expectations, conversations about acculturation, differences in value orientation, and discomfort with implementing new intervention skills. Dialogue from interventionist and youth exchanges is presented to illustrate how these themes emerged and were addressed by interventionists in a culturally responsive manner. The study highlights how IPT–AST with immigrant family and Asian American youth may unfold differently compared to youth from nonimmigrant families. Implications of findings for providers are discussed.     

Emotional face recognition in autism and in cerebral visual impairments: In search for specificity

Autism spectrum disorder (ASD) is characterized by difficulties in the social domain, but also by hyper- and hypo-reactivity. Atypical visual behaviours and processing have often been observed. Nevertheless, several similar signs are also identified in other clinical conditions including cerebral visual impairments (CVI). In the present study, we investigated emotional face categorization in groups of children with ASD and CVI by comparing each group to typically developing individuals (TD) in two tasks. Stimuli were either non-filtered or filtered by low- and high-spatial frequencies (LSF and HSF). All participants completed the autism spectrum quotient score (AQ) and a complete neurovisual evaluation. The results show that while both clinical groups presented difficulties in the emotional face recognition tasks and atypical processing of filtered stimuli, they did not differ from one another. Additionally, autistic traits were observed in the CVI group and symmetrically, some visual disturbances were present in the ASD group as measured via the AQ score and a neurovisual evaluation, respectively. The present study suggests the relevance of comparing ASD to CVI by showing that emotional face categorization difficulties should not be solely considered as autism-specific but merit investigation for potential dysfunction of the visual processing neural network. These results are of interest in both clinical and research perspectives, indicating that systematic visual examination is warranted for individuals with ASD.     

Bracing for loss

People find unexpected bad news aversive and often brace themselves by predicting the worst. Three experiments examined whether the pessimism is influenced by personal need. Students who differed in financial need learned that a billing error meant that some students would receive an additional bill from their university. Financially needy students were consistently pessimistic in predicting their likelihood of receiving a bill, whereas non-needy students were not. In addition, the experiments reveal that (a) the pessimism occurred for potential losses but not potential gains, (b) needy students were pessimistic about their own chances but not the chances of a friend, (c) the pessimism was not attributable to needy students' being more readily primed by the news of a possible bill or to needy students' having more experience with billing errors, and (d) the pessimism was specific to monetary losses and did not generalize to other events.     

Does the contextual interference effect last over extended transfer trials?

The contextual interference effect (random practice yields better transfer and retention compared to blocked practice) detected in a study of 24 boys and 33 girls randomly selected (M age = 10.5 yr., SD = .6) performing a linear positioning motor task seemed to dissipate in extended transfer trials.     

Two measures of affect and emotion in Italian children aged 6 to 11 years

The authors investigated the relation between affective and cognitive processes in fantasy play and emotional understanding of 50 Italian children (25 boys and 25 girls) enrolled in regular elementary school in Northern Italy. Children were administered a standardized play task, the Affect in Play Scale, and answered questions about their understanding of emotions. Consistent, yet modest, relationships were found between dimensions of fantasy play and emotional understanding.     

How is emergent writing based on drawing? Analyses of children's products and their sorting by children and mothers

Writing and drawing produced by children 28-53 months old were compared. Israeli and Dutch preschoolers were asked to draw and write, to classify their products as drawing and writing, and to decide what they had drawn or written. Israeli and Dutch mothers classified the products. Scores on a scale for writing composed of graphic, "writing-like," and symbolic schemes showed improvement with age. Recognition of drawings as drawings preceded recognition of writings as writings. Scores on writing and drawing were substantially correlated, even with age partialed out, suggesting (a) that when children start drawing objects referentially, they write by drawing "print" and (b) that progress in object drawing involves progress in drawing print, so that their writing becomes more writing-like. Children unable to communicate meaning by writing spontaneously resort to drawing-like devices, indicating the primacy of drawing as a representational-communicative system.
