Oscillator-based memory for serial order

A computational model of human memory for serial order is described (OSCillator-based Associative Recall [OSCAR]). In the model, successive list items become associated to successive states of a dynamic learning-context signal. Retrieval involves reinstatement of the learning context, successive states of which cue successive recalls. The model provides an integrated account of both item memory and order memory and allows the hierarchical representation of temporal order information. The model accounts for a wide range of serial order memory data, including differential item and order memory, transposition gradients, item similarity effects, the effects of item lag and separation in judgments of relative and absolute recency, probed serial recall data, distinctiveness effects, grouping effects at various temporal resolutions, longer term memory for serial order, list length effects, and the effects of vocabulary size on serial recall.     

Reception and transmission of infant vocalizations with dedicated telephone lines

A remote control home amplifier is described that allows the investigator to use dedicated telephone lines between the laboratory and the home to record infant vocalizations and provide auditory stimulation to the infant. The procedure allows daily test sessions with the infant, and several infants can be studied each day with one set of laboratory equipment.     

Coping with interpersonal stress: role of big five traits

Seventy-one couples living in a stepfamily context reported interpersonal family stressors and related coping strategies daily for 1 week in a daily process study. The role of personality and of the stressful context in each of the spouse's coping was examined. Personality was assessed via the Five-Factor Model (Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness). Two types of stressors emerged as primary dimensions of stepfamily stress: marital conflict and child misbehavior. These were treated as contextual factors in multilevel modeling analyses examining the independent and interactive effects of personality and situation on coping. Nine subscales of coping were examined based on three main functions of coping: problem-, emotion- and relationship-focused. Both the situational context and the five dimensions of personality examined were significantly and independently related to coping-strategy use. Moreover, there were significant personality-by-context interactions. The present study highlights the importance of considering personality in context when examining coping behaviors.     

Assessing Emotional Reactivity: Psychometric Properties of the Perth Emotional Reactivity Scale and the Development of a Short Form

The Perth Emotional Reactivity Scale (PERS) is a 30-item self-report measure of trait levels of emotional reactivity. In this article, we examine the psychometric properties of the PERS subscale and composite scores in an adult community sample (N = 428), and develop an 18-item short form of the measure (PERS–S). The PERS and PERS–S are designed to assess the typical ease of activation, intensity, and duration of one's emotional responses, and do so for positive and negative emotions separately. Our confirmatory factor analyses supported that the PERS and PERS–S both had the same theoretically congruent factor structure, and that all subscale and composite scores displayed high internal consistency reliability. Correlations with scores from established measures of psychopathology and emotion regulation also supported the validity of PERS and PERS–S scores. Our data therefore suggest that the PERS–S subscale and composite scores retain the psychometric strengths of their longer PERS counterparts. We conclude that both forms of the measure have good utility. Clinical and research applications are discussed.     

Assessing Alexithymia: Psychometric Properties and Factorial Invariance of the 20-Item Toronto Alexithymia Scale in Nonclinical and Psychiatric Samples

The 20-item Toronto Alexithymia Scale (TAS-20) is a self-report questionnaire designed to measure the three components of alexithymia; difficulty identifying feelings in the self (DIF), difficulty describing feelings (DDF), and externally orientated thinking (EOT). We examined the scale’s psychometric properties in Australian nonclinical (N = 428) and psychiatric (N = 156) samples. In terms of factorial validity, confirmatory factor analyses found the traditional 3-factor correlated model (DIF, DDF, EOT) to be the best and most parsimonious solution, but it did not reach adequate levels of goodness-of-fit in either sample. Several EOT items loaded poorly on their intended factor, and a reverse-scored item method factor was present; the factor structure of the scale was invariant across both samples. A higher-order factor model (with a single higher-order factor) was slightly inferior to the correlated models, but still tenable. The total scale score and DIF and DDF subscales displayed sound internal consistency, but the EOT subscale did not. We conclude that the TAS-20 has, for the most part, adequate psychometric properties, though interpretation should focus only on the total scale score and DIF and DDF subscales; we recommend the EOT subscale score not be used. Implications for clinical use and future revision of the scale are discussed.     

Family Resilience and the Management of Fibromyalgia: Implications for Family Therapists

Fibromyalgia Syndrome (FMS) is one of the most troubling rheumatic disorders for patients, significant others, and the health care providers who treat them. Responses from 150 participants provided valuable information on the relationship between family resilience and the management of fibromyalgia. Self reported family stressors, strains, and distress were significantly associated with an increase in health problems/functional disability, whereas family hardiness and family social support were associated with a decrease. Family stressors and family strains were also positively associated with the frequency of medication use. Medical family therapy interventions that consider the familial context are recommended for treatment. Additional implications for clinical practice and future research are discussed. J.
