Results of EMG analysis using the Polish mini-computer ANOPS

During a study tour of the Neurological Clinic in Warsaw, the automatic EMG analysis procedure by means of the Polish computer ANOPS was tested, standard values worked out and their diagnostic information value tested on patients with neuromuscular diseases. To obtain normal values, leads from four muscles of each of 21 healthy persons were made and the electromyograms of each muscle described by five different parameters. For a differentiated neuromuscular diagnosis it is significant that the computer not only calculates the mean values of each EMG parameter but provides histograms from which further statistical indices and diagnostic information can be obtained.     

Examining Links Between Infant Parasympathetic Regulation during the Still-Face Paradigm and Later Callous-Unemotional Traits

Research on Child and Adolescent Psychopathology - Although research suggests that callous-unemotional (CU) traits are underpinned by deficits in social affiliation and reduced sensitivity to...     

Choices and preferences: Evidence from implicit choices and response times

We present a new experimental paradigm where choice-induced preference change is measured for alternatives which are never compared directly, but rather confronted with other alternatives in a way which keeps choices predictable without exogenously manipulating them. This implicit-choice design improves on the free-choice paradigm, avoiding the recently criticized selection bias. Rating and ranking spreads in two experiments show that preference-based choices feed back into and alter preferences even if choices are not directly among similarly evaluated alternatives. In agreement with recent brain-imaging evidence, response time measurements for direct choice pairs in our experiments indicate that reappraisal processes are already triggered during decision making, with larger post-choice spreads (sharper attitude change) being associated to quicker decisions.     

The phonotactic influence on the perception of a consonant cluster /pt/ by native English and native Polish listeners: A behavioral and event related potential (ERP) study

The effect of exposure to the contextual features of the /pt/ cluster was investigated in native-English and native-Polish listeners using behavioral and event-related potential (ERP) methodology. Both groups experience the /pt/ cluster in their languages, but only the Polish group experiences the cluster in the context of word onset examined in the current experiment. The /st/ cluster was used as an experimental control. ERPs were recorded while participants identified the number of syllables in the second word of nonsense word pairs. The results found that only Polish listeners accurately perceived the /pt/ cluster and perception was reflected within a late positive component of the ERP waveform. Furthermore, evidence of discrimination of /pt/ and /p?t/ onsets in the neural signal was found even for non-native listeners who could not perceive the difference. These findings suggest that exposure to phoneme sequences in highly specific contexts may be necessary for accurate perception.     

Structure of the Personality Beliefs Questionnaire-Short-Form: Smallest Space Analysis

Butler et al. (Cognitive Therapy and Research 31:357?C370, 2007) developed the Personality Beliefs Questionnaire-Short Form (PBQ-SF), from an earlier longer version (Beck and Beck 1991), to assess the types of schemata associated with different personality disorders. This study explored the structure of PBQ-SF using Guttman??s Smallest Space Analysis. Participants were 228 students who volunteered for the study. The two facets (each with two subsets) suggested by the analysis to characterize the structure of the personality disorder subscales were Ego Concerns (self-enhancement versus self-protection) and Control Concerns (feelings lack of control versus need for control). Clinical implications of the findings include targeting major dysfunctional thinking, as suggested by the aforementioned two facets and their subsets, in the treatment of personality disorders.     

Differentiation of Assaultive Delinquents with the Hand Test

The AOS score on the Hand Test significantly differentiated assaultive from non-assaultive delinquents, correctly categorizing 78 percent of the subjects.     

Differentiation of Aggressive Behavior of Institutionalized Schizophrenics with the Hand Test

Changes and trends in personality assessment documented through examination of the first issues of the Journal of Personality Assessment (JPA) for the years 1937 to 1997 revealed the following: (a) compared to the Journal of Personality and PsychologicalReview, JPA published more women first authors and coauthors in every issue except in 1987; (b) of the total 8,524 individuals whose assessment protocols comprised data sets in the 7 issues, l,6 15 (19%) were patients and 4,839 (57%) were undergraduate college students; (c) combining patients and nonpatients, the average age of children under 13 was 12.24 years, the average age of high school students was 15.28 years, and the average age of adults was 24.20 years; (d) only 6% of the participants were identified as African American, Mexican American, Asian Americans, or other; and (e) in the 74 articles examined, 98 different tests, techniques, or tasks to assess personality were discussed. We suggest that future research should include a more diverse group of participants that includes more older people and more people of color.     

Preschoolers' Inhibition in Their Home: Relation to Temperament

Researchers assessed 58 preschoolers' reactions to an unfamiliar person and unfamiliar objects in their familiar home environment. Children participated in a 30-min procedure designed to elicit behavioral inhibition, including (a) a free-play period with a stranger present, (b) a structured interaction with the stranger, and (c) uncertainty-eliciting tasks. Behaviors representing the child's reactions toward the mother, stranger, and novel objects were coded. Mothers completed a temperament scale. Preschoolers exhibited behaviors indicative of inhibition toward unfamiliar social and nonsocial stimuli; behaviors remained stable across increasingly intrusive episodes. The approach/withdrawal component of temperament was related to behavioral inhibition. Individual differences in mood did not appear to be related to differences in inhibition. Parent reported temperament was related to researcher-observed behaviors.
