Bias effects in word fragment completion in young and older adults

Young and older adults were tested on a word fragment completion task in which correct solutions were studied words, words orthographically similar to studied words, or new words. In Experiments 1 and 2, the standard production version of the word fragment completion task was used; older adults had reduced benefits of prior exposure to target words and slightly decreased costs. However, costs and benefits did not differ across age in a forced-choice version of the task (Experiment 3). At a behavioral level, the results are contrary to predictions that age differences in word fragment completion priming effects will be greater when there is a strong competitor for the correct solution and that age differences in both costs and benefits will be smaller for identification than for production tasks. Theoretical implications of these findings are considered.     

Lexical representations of written nouns and verbs in Italian

This study investigates the differences in the input representations of verbs and nouns in the Italian mental lexicon. One visual lexical decision experiment in which the stem homograph effect (Laudanna, Badecker, and Caramazza, 1989) was evaluated on noun and verb targets is reported. Strong inhibitory effects on verb targets preceded by stem homographs relative to nonhomographic word pairs were found. The effects on verb targets were also much more reliable than the effects on noun targets. The pattern of results provides support for the hypothesis that noun and verbs are differently represented in the orthographic input lexicon.     

Body Dissatisfaction in Women and Men: The Role of Gender-Typing and Self-Esteem

Body dissatisfaction was studied in 589 predominately middle class, European American, college students, classified as masculine-typed, feminine-typed, androgynous, or undifferentiated using the Personal Attributes Questionnaire. Body dissatisfaction was defined as the discrepancy between a drawing selected as describing the individual's body and their selection of drawings representing: (1) their ideal body; (2) the body they believed members of their sex preferred; and (3) the body they believed members of the opposite sex preferred. Two separate studies found that women classified as feminine-typed or undifferentiated were more dissatisfied with their bodies than were women classified as masculine-typed or androgynous. Similar results were found for men. Both studies also found that women, regardless of gender-type, had thin ideals and greatly overestimated male preferences for slender female bodies. The theoretical implications of these results for gender schema theory and two other theories of gender typing were discussed. It was concluded that it is unnecessary to appeal to complex theories of gender-mediated socialization in order to explain differences in body dissatisfaction in women or men. Instead, these differences are most parsimoniously understood as the consequences of differences in global self-esteem.     

Young Children's Descriptions of God: Influences of parents' and teachers' God concepts and religious denomination of schools

This study extends prior research on antecedents of individual differences in God concepts in early childhood by examining relations of parents' and teachers' God concepts and religious denomination of schools with children's God concepts. Participants were 165 preschoolers (mean age 63 months), 107 of their parents and 16 teachers. These subjects were distributed over eight elementary schools belonging to four different religious denominations, i.e. Catholic, Dutch Reformed, Orthodox Reformed and State schools. The God concepts of children, parents and teachers were measured using interviews and questionnaires. Results showed that both parents' and teachers' God concepts were predictive of children's God concepts, but each in a different way. Parents seem to influence the relational component of children's God concepts particularly. Teachers especially contribute to biblical content of children's God concepts. Religious denomination of schools had independent effects on children's God concepts, controlling for parental denomination.     

Psychological Contours of Multicultural Feminist Hermeneutics: Han and Relationality

The two key psychological contours, han and relationality, in interpreting and understanding biblical texts among Korean/Asian North American women are discussed. The Old Testament biblical narrative of Jephthah’s daughter (Judges 11) is employed in order to demonstrate how the concepts and the interconnectedness of han and relationality are being played out in the minds of Korean/Asian North American women. Some practical suggestions are offered for preachers, Bible teachers, pastoral counselors, and caregivers in assisting Korean/Asian North American women with their hermeneutical processes.

Prospective memory and pediatric traumatic brain injury: effects of cognitive demand.

This study investigated the effects of pediatric traumatic brain injury (TBI) on prospective memory. Fourteen children and 14 adolescents with TBI were compared with 25 and 23 noninjured children and adolescents, respectively. Based on a prefrontal model, the cognitive demand on the ongoing component of a prospective-memory task was manipulated. Overall, those with TBI had poorer prospective-memory performance than their noninjured peers. Performance was worse in a high cognitive-demand condition than a low, and younger children performed worse than adolescents. Decreases in performance from the low- to high-demand conditions were not significantly different between the two children's groups but were between the two adolescents' groups. Furthermore, the age and injury effects were reflected in the performances on executive function tests: the Self-ordered Pointing Task (SOPT), and the Stroop Color Word Interference Test. The Tower of London (TOL), which did not produce age or injury effects, was nevertheless found to be an important predictor of performance on the high-demand task in those with TBI. Although previous research has demonstrated impaired prospective memory performance in children with TBI, this study attempted to explain why this might occur, specifically that the prefrontal regions might be implicated.     

Active avoidance conditioning in zebrafish (Danio rerio)

The zebrafish represents a potentially useful organism for studying genes involved in learning and memory function in vertebrates, because a number of genetic techniques in zebrafish have been developed to produce a wide variety of genetic mutants. While zebrafish mutants are being developed, behavioral studies on learning and memory function in zebrafish are in urgent need. The present study investigated active avoidance conditioning in normal zebrafish. Zebrafish were trained to swim from a lighted (CS) compartment to a dark compartment to avoid an electrical body shock (US) in a shuttle-box that consisted of a water-filled tank separated by an opaque barrier into two equal compartments. By varying the number of trials per training session and the duration of the intertrial interval, Experiments 1 and 2 showed that, with the CS, US, and intertrial interval being 12s, zebrafish learned avoidance responses within a training session consisting of 30 trials and retained the avoidance responses. Experiment 3 showed that zebrafish learned avoidance responses following the association between the CS of light and the US of shock in the avoidance conditioning paradigm. Using the avoidance conditioning paradigm, Experiment 4 investigated the amnestic effects of N-methyl-D-aspartate receptor antagonist MK-801 and nitric oxide synthase inhibitor L-NAME in zebrafish. Experiment 4 showed that post-training injection of L-NAME significantly impaired retention of avoidance responses while MK-801 did not, confirming previous results with other vertebrates. The results of the present study suggest the similar involvements of neurochemicals in learning and memory among vertebrates. Thus, future studies with zebrafish mutants may identify genes involved in learning and memory in vertebrates.     

Prolonged exposure therapy for chronic combat-related PTSD: a case report of five veterans

Prolonged exposure (PE) therapy has been found efficient in reducing posttraumatic stress disorder (PTSD) symptoms mostly among rape victims, but has not been explored in combat-related PTSD. Five patients with severe chronic PTSD, unresponsive to previous treatment (medication and supportive therapy) are described. Patients were evaluated with the PTSD Symptom Scale-Interview, and Beck Depression Inventory, before and after 10-15 sessions of PE therapy. All five patients showed marked improvement with PE, with a mean decrease of 48% in PTSD Symptom Scale-Interview score and 69% in Beck Depression Inventory score. Moreover, four patients maintained treatment gains or kept improving 6-18 months after the treatment. The results suggest that PE was effective in reducing combat-related chronic PTSD symptoms.     

Effects of reactivity to observations on staff performance

We examined reactivity of staff behavior to observations of their work performance. After training 2 job coaches to reduce completion of break activities for supported workers, we evaluated job-coach behavior using both conspicuous and inconspicuous observations. Results indicated that both coaches completed none of the activities when observations were conspicuous but most of the activities when observations were inconspicuous. Subsequently, job coaches were taught to self-record their performances, and their completion of activities remained low with inconspicuous observations. Implications of reactivity are discussed for investigations that target staff behavior.     

How time flies: a study of novice skydivers

Although time distortion is commonly reported during a traumatic experience, there is little research addressing the phenomenon. This study investigated the role of affect in time perception in a very stressful experience by indexing novice tandem skydivers' (N=76) levels of fear and excitement before the skydive and soon after landing. Estimations of how long skydivers thought their experience lasted were obtained after landing. Whereas increased fear was associated with the perception of time passing slowly, increased excitement was associated with the perception of time passing quickly. These data support models of time perception based on avoidance and approach motivations influencing time distortion.
