Mapping of the Anatomical Circuit of CaM Kinase-Dependent Courtship Conditioning in Drosophila

Globally inhibiting CaM kinase activity in Drosophila, using a variety of genetic techniques, disrupts associative memory yet leaves visual and chemosensory perception intact. These studies implicate CaM kinase in the plastic processes underlying learning and memory but do not identify the neural circuitry that specifies the behavior. In this study, we use the GAL4/UAS binary expression system to define areas of the brain that require CaM kinase for modulation of courtship conditioning. The CaM kinase-dependent neurons that determine the response to the mated female during conditioning and those involved in formation and expression of memory were found to be located in distinct areas of the brain. This supports the idea that courtship conditioning results in two independent behavioral modifications: a decrement in courtship during the conditioning period and an associative memory of conditioning. This study has allowed us for the first time to genetically determine the circuit of information flow for a memory process in Drosophila. The map we have generated dissects the behavior into multiple components and will provide tools that allow both molecular and electrophysiological access to this circuit.     

Phonological Short-term Memory and Foreign Language Learning

This study investigated links between short-term memory skills and children's abilities to learn the vocabulary of a foreign language taught in school. Forty-five Greek children who were learning English as a foreign language were assessed on their short-term memory in both languages, and on their knowledge of both native and foreign vocabulary. Knowledge of native and foreign vocabulary shared highly significant associations with the phonological short-term memory measures. However, vocabulary scores in the two languages shared a close relationship that could not be explained exclusively in terms of phonological loop capacity. Implications of these findings for theoretical accounts of how words are learned in the native and foreign language are considered.     

Linkages of School Structural and Socioenvironmental Characteristics to Parental Satisfaction With Public Education and Student Academic Achievement

This study examined school climate's relation to the sociodemographic composition of the school student population, school structural characteristics, parental involvement, classroom support in learning, parental satisfaction with public education, and student academic achievement all together at one time in a sample of 122 elementary schools. Parental satisfaction was best predicted by parental perceptions of a safe school and positive climate, followed by the school's informing parents of their child's educational progress and empowering parents. Student performance on a standardized achievement was best predicted by the percentage of students in the Free and Reduced Meals program, parental perceptions of a safe school, and parental involvement. Study results are discussed in terms of two general levels (school and classroom) and types (task support and interpersonal support) of the school's social environment.     

Human responses to various conditions of water temperature

Skin-surface temperatures on thehuman hand were obtained immediately following six exposure times ranging from 5 to 60 sec. for water temperatures varying in 5° increments from 10° to 40°C. The surface of the skin was found to respond rapidly and regularly to both the temperature and time of exposure. In a second study 30 Ss exposed a hand for 5 or 30 sec. to water temperatures ranging from 10° to 45°C. and made ratings on scales of pain and comfort as well as attaching a verbal label (cold, cool, tepid, etc.) to each experience. The experience of cold became more intense over these time intervals while the experience of warmth became less, and with the threshold constant taken into account the sensations of pain and discomfort were found to follow a psychophysical power law. The usefulness of these sorts of data for interpreting the effects of noxious stimuli in basic learning studies is discussed.     

Bediüzzaman Said Nursi and Louis Massignon in Pursuit of God's Word: A Muslim and a Christian on the Straight Path

Said Nursi (1876–1960) and Louis Massignon (1883–1962) were contemporaries. Both of them were men of God in whose lives dramatic turning points changed the direction of their thinking and led them to devote themselves to the cause of re-awakening the religious consciousness of the people of their time. This article explores the striking parallels in their personal journeys, offers a comparison of their leading ideas and describes the far-reaching effects their lives and works have had in their respective faith communities. The biographies of faithful witnesses in modern times in both Islam and Christianity have much to teach those of us in the twenty-first century who seek to find the way to a harmonious convivencia for our two, global faith communities.     

Psychological Factors Associated with Emotional Responses to Receiving Genetic Risk Information

This study identified levels of distress, and predictors of levels of distress, in women undergoing assessment for genetic risk of breast/ovarian cancer based on their family history. It comprised a cohort study following 154 women who completed questionnaires at entry into a cancer genetic assessment programme and following risk provision. Independent significant associates of anxiety following risk provision were age, neuroticism, feeling hopeless about developing cancer, a perceived lack of control over developing cancer, lack of a social confidant, and a coping response involving acceptance/resignation. Depression was associated with age, neuroticism, feeling hopeless about developing cancer, lack of social confidant, and a coping response involving acceptance/resignation. To avoid high levels of psychological morbidity in future cohorts undergoing cancer genetic risk assessment, information should be given that emphasises that some degree of control over health outcomes through behaviour change or increased surveillance is possible.     

Towards a rich view of auditory experience

In this paper I will argue that the gender properties expressed by human voices are part of auditory phenomenology. I will support this claim by investigating auditory adaptational effects on such properties and contrasting auditory experiences, before and after the adaptational effects take place. In light of this investigation, I will conclude that auditory experience is not limited to low-level properties. Perception appears to be much more informative about the auditory landscape than is commonly thought.     

Reform of statistical inference in psychology: The case of<Emphasis Type="Italic">Memory &; Cognition</Emphasis>

Geoffrey Loftus, Editor ofMemory & Cognition from 1994 to 1997, strongly encouraged presentation of figures with error bars and avoidance of null hypothesis significance testing (NHST). The authors examined 696Memory & Cognition articles published before, during, and after the Loftus editorship. Use of figures with bars increased to 47% under Loftus’s editorship and then declined. Bars were rarely used for interpretation, and NHST remained almost universal. Analysis of 309 articles in other psychology journals confirmed that Loftus’s influence was most evident in the articles he accepted for publication, but was otherwise limited. An e-mail survey of authors of papers accepted by Loftus revealed some support for his policy, but allegiance to traditional practices as well. Reform of psychologists’ statistical practices would require more than editorial encouragement.     

Rise in landing-related skydiving fatalities

The purpose was to assess whether adoption of potentially dangerous skydiving gear and skydiving practices has led to an increase in fatalities. Beginning in the early 1990s, civilian skydivers began to utilize high performance parachutes that fly much faster and are much more responsive than older style parachutes. Also, skydivers began to fly these parachutes in a more aggressive manner. An analysis of data from the 507 skydiving fatalities in the USA between 1986 and 2001 indicated that this shift toward high performance parachutes and aggressive flying techniques was temporally associated with an increase in parachute-landing deaths. During the same time period, the total number of fatalities remained fairly stable.     

The disclosure dilemma for gay men and lesbians: "coming out" at work

This study examined disclosing sexual orientation at work for 220 gay men and 159 lesbians. Self-acceptance, the centrality of one's identity, how "out" one is to friends and family, employer policies, and perceived employer gay-supportiveness were associated with disclosure behaviors at work for gay/lesbian employees. Disclosing at work and working for an organization perceived to be more gay supportive was related to higher job satisfaction and lower job anxiety. Reactions of coworkers to gay or lesbian workers mediated the relationship between disclosure and gay/lesbian workers' job attitudes. Implications and solutions for management are discussed.
